DETAILED DESCRIPTION OF THE DRAWINGS

[0288] In the below detailed description of the various embodiments described with reference to the drawings, the same reference numerals are used throughout the figures identifying identical components described only once in the first occurrence of the element. Elements or components serving the same purpose or being configured similar to previously described components or elements, respectively, are designated the same reference numeral as previously indicated, however, added a marking to identify the geometrical difference from the previously described component or element, still, to the use of the same integer identifying the correspondence as to function and structure. It is further contemplated that elements or components from one embodiment described below may readily be combined with another embodiment with reference to a different figure, as the various variants of embodiments are readily interchangeable and/or elements or components from one embodiment being readily substituted with or by components or elements of another embodiment.

[0289] FIG. 1A shows a perspective view of a first embodiment of a pelt board 10 in the contracted state. The pelt board 10 comprises a lower part 12 and an upper part 14. The lower part 12 comprises a first arched wall element 16, a second wall element 18, a third wall element 20, a fourth wall element 22 which together define a cavity 24 in which an elongated core element 26 is located. The first arched wall element 16, the second wall element 18, the third wall element 20 and the fourth wall element 22 are shown here schematically as being solid, it is however understood that for optimal drying of the pelt, they should be louvered for allowing ventilation air to pass from the pelt board to the pelt. The upper part 14 comprise a fifth wall element 28 and a sixth wall element 30, both which in the present case are arched and tapered but which also may be made non-arched and non-tapered. The elongated core element 26 extends into the upper part 14 in the form of a core extension element 26.

[0290] The first wall element 16 and the second wall element 18 comprises respective peripheral elements 16 16 18 18, which are flexibly connected to the center elements of the respective first wall element 16 and the second wall element 18. The third wall element 20 will in the present contracted state overlap the peripheral elements 16 18 and the fourth wall element 20 will in the present contracted state overlap the peripheral elements 16 18. The fifth wall element 28 and a sixth wall element 30 both mutually overlap each other. An extension element 32 is interconnecting the lower part 12 and the upper part 14.

[0291] FIG. 1B shows a perspective view of the first embodiment of the pelt board 10 in the expanded state. By pushing the elongated core element 26 in a longitudinal direction as shown by the arrows, the wall elements are all forced in outwardly oriented directions as shown by the arrows. The first wall element 16 and the fifth wall element 28 are moved along a first radial dimension while the second wall element 18 and the sixth wall element 30 are moved along the first radial dimension but in the opposite direction, the first radial dimension being perpendicular to the longitudinal direction defined by the elongated core element 26. The third wall element 20 and the fourth wall element 22 are forced in opposite directions along a second radial direction as shown by the arrows, which second radial direction is perpendicular to both the first radial dimension and to the longitudinal dimension. The peripheral portions 16 16 18 18 of the respective first wall element 16 and second wall element 18 move along both the first and second radial dimensions such that the expanded pelt board 10 form a smooth outer surface.

[0292] FIG. 2A shows a cut-out perspective view of another embodiment of a pelt board 10 in the contracted state. The third wall element 20 and the fourth wall element 22 comprise actuator members 34 along the longitudinal dimension and the elongated core element 26 comprise cooperating members 36 along the longitudinal dimension. The actuator members 34 and cooperating members 36 define opposing wedges. In the contracted state of the pelt board 10, the sloping surfaces of the opposing wedges are non-overlapping or overlapping such that no outwardly oriented force is generated, i.e. that the protruding portions of the opposing wedges are non-overlapping.

[0293] The fifth wall element 28 and the sixth wall element 30 comprise actuator members 34 along the longitudinal dimension and the elongated core element 26 comprise cooperating members 36 along the longitudinal dimension. The actuator members 34 define curved grooves along the longitudinal dimension of the fifth wall element 28 and the sixth wall element 30 whereas the cooperating members 36 define pins of the core extension element 26.

[0294] FIG. 2B shows a cut-out perspective view of the pelt board 10 in the expanded state. The sloping surfaces of the opposing wedges are now overlapping such that an outwardly oriented force is achieved, i.e. the protruding parts of the opposing wedges are overlapping causing the third wall element 20 and the fourth wall element 22 to move outwardly in opposite directions.

[0295] When the core extension element 26 moves together with the elongated core element 26 along the longitudinal dimension, the pins constituting the cooperating members 36 move along the curved grooves constituting the actuator members 34 and thereby causing the fifth wall element 28 and the sixth wall element to move outwardly in opposite directions.

[0296] The movement of the first wall element 16 and the second wall element 18 will be explained in detail in the following figures.

[0297] FIG. 3 shows a perspective view of a further embodiment of a pelt board 10. In the present embodiment, the fifth wall element 28 and the sixth wall element 30 are substantially flat in order to be able to accommodate the neck part of the animal pelt. The surface of the arched wall elements 16 18 20 22 have ribs 38 for allowing the pelt to be properly fixated to the pelt board 10. Further all of the wall elements 16 18 20 22 have ventilation holes 40.

[0298] FIG. 4 shows a perspective view of the upper part 14 of the pelt board 10. It shows in detail how the fifth wall element 28 and the sixth wall element 30 both connect to the core extension element 26. The actuator elements 34 in form of curved grooves connect to the cooperating members 36 in the form of pins. By longitudinal movement of the core extension element 26, the pins will follow the path defined by the curved grooves and thus cause the fifth wall element 28 and the sixth wall element 30 to move outwardly along the curve defined by the interaction between the curved grooves and the pins.

[0299] FIG. 5 shows a perspective view of the lower part 12 of the pelt board 10. In the present embodiment the first wall element 16 is composed of two elements designated the reference numerals 16A and 16B which are interconnected by means of a snap fit connection 42. Also, the second wall element 18 is composed of two elements designated the reference numerals 18A and 18B and which are interconnected by means of a snap fit connection 42.

[0300] FIG. 6A shows a perspective view of the lower part 12 of the pelt board 10. The present view especially shows a close-up view of the elements 16A 16B 18A 18B making up the first wall element 16 and the second wall element 18, respectively. In order to make the first wall element 16 and the second wall element 18 move in the first radial direction, the snap fit mechanisms 42 42, when assembled, define actuator members 34 in the form of pins. The elongated core element 26 defines cooperating members 36 in the form of curved grooves. The working principle of the curved groove and the pin is the same as for the upper part of the pelt board 10. The pins are guided by the curved grooves and forced inwardly/outwardly according to the longitudinal movement of the elongated core element 26. Thereby, the first wall element 16 and the second wall element 18 move along the first radial dimension and at the same time the first wall element 16 and the second wall element 18 are held by the elongated core element 26.

[0301] The wall elements 16A 16B 18A 18B also each comprise a number of respective peripheral parts 44 which are flexibly connected to its corresponding wall elements 16A 16B 18A 18B.

[0302] FIG. 6B shows a perspective view of the lower part 12 of the pelt board 10 when assembled. When interconnected, each of the snap fit mechanism 42 42 will form a pin 34 to be guided in the curved groove of the elongated core element 26. The peripheral parts 44, which will be described in detail below, form a substantially smooth and continuous surface together with it corresponding wall element 16 18.

[0303] FIG. 7A shows a close up view describing the functional principle of the elongated core element 26, the wall element 16A and the corresponding peripheral part 44. The present view represents the contracted state of the pelt board. The elongated core element 26 comprises a further cooperating member 36 constituting a wedge and which is adapted to cooperate with an actuator member 34 constituting a protrusion on the peripheral part 44.

[0304] FIG. 7B shows the setup of FIG. 7B when in the expanded state. The elongated core element 26 moves in the longitudinal direction relative to the wall element 16a and causes the wall element 16A to move outwardly in the first radial direction as shown by the arrows. The outwardly movement of the wall element 16A is caused by the interaction between the cooperating member 36 and the actuator member 34. The longitudinal movement of the elongated core 26 causes the actuator member 34 constituting a protrusion to slide on the cooperating member 36 constituting a wedge and thereby the peripheral part 44 is caused to move outwardly in both the first and second radial directions as shown by the arrow.

[0305] FIG. 8A shows a perspective view illustrating how the third wall element 20 and the fourth wall element 22 are fastened together and to the elongated core element 26. The third and fourth wall elements 20 22 each comprise further actuator members in the form of fastening members 46, which are cooperating with corresponding tracks 48 of the elongated core element 26. The third and fourth wall elements 20 22 are in the present embodiment additionally joined together via corresponding clip-on mechanisms 50 50 at the bottom end of the pelt board.

[0306] FIG. 8B shows the lower part 12 of the pelt board when the third wall element 20 and the fourth wall element 22 are fastened together and to the elongated core element 26.

[0307] FIG. 9A shows a close-up view illustrating the working principle of the third wall element 20 and the fourth wall element 22. The third wall element 20 and the fourth wall element 22 each comprise actuator members 34 and the elongated core element 26 comprises cooperating members 36. The actuator members 34 and the cooperating members 36 define wedges having sloped in opposite direction. In the present contracted state, the wedges of the actuator members 34 and the cooperating members 36 are located such that the protruding parts of the wedges are non-overlapping, allowing the third wall element 20 and the fourth wall element 22 to define a small distance between themselves. The fastening members 46, described in detail in the previous figure, will in the present case be interacting with the corresponding tracks 48 of the elongated core element 26 such that each of the third wall element 20 and the fourth wall element 22 are pulled inwardly towards the elongated core element 26.

[0308] FIG. 9B shows a close-up view illustrating the working principle of the third wall element 20 and the fourth wall element 22 when in the expanded state. In the present expanded state, the wedges of the actuator members 34 and the cooperating members 36 are located such that the protruding parts of the wedges are overlapping, causing the third wall element 20 and the fourth wall element 22 to define a larger distance between themselves. The moving principle of the third wall element 20, the fourth wall element 22 and the elongated core element 26 is illustrated by the arrows.

[0309] FIG. 9C shows a close-up view illustrating the working principle of the fastening member 46 when the pelt board is in the expanded state. The fastening member 46 has a wedged shape for controlling the distance between the elongated core element 26 and the respective third wall element 20 and the fourth wall element 22 depending on the longitudinal position of the elongated core element 26. The fastening member 46 of the respective third wall element 20 and the fourth wall element 22 grasps the track 48 of the elongated core element 26 which is located opposite the third wall element 20 of which the present fastening member 46 is part of.

[0310] FIG. 9D shows a close-up view illustrating the working principle of the fastening member 46 when the pelt board is in the expanded state. The contraction of the wall third wall element 20 and the fourth wall element 22 may be controlled in that the slope of the fastening member causes the third wall element 20 and the fourth wall element 22 to move closer to the elongated core element 26 when the pelt board is assuming the contracted state.

[0311] FIG. 10A shows the mounting principle of the upper part 14. In the first step, the fifth wall element 28 and the sixth wall element 30 are positioned in a partial overlapping position about the core extension element 26. In the next step, the cooperating members 36, which constitute pins, are positioned through the actuator members 34, which constitute curved grooves, and through the center of the core extension element 26.

[0312] FIG. 10B shows a perspective view of the upper part 14 when mounted and when in the expanded state.

[0313] FIG. 11A shows the moving principle of the upper part 14 of the pelt board. The cooperating members 36 are guided in the actuator members 34 for causing the fifth wall element 28 and the sixth wall element 30 to minimize the radial dimension between themselves and relative to the core extension element 26.

[0314] FIG. 11B shows the moving principle of the upper part 14 of the pelt board. The cooperating members 36 are guided in the actuator members 34 for causing the fifth wall element 28 and the sixth wall element 30 to increase the radial dimension between them and relative to the core extension element 26 when the core extension element 26 is moved in the longitudinal direction as shown by the arrows.

[0315] FIG. 12A shows a perspective view of a further embodiment of a pelt board 10. The pelt board 10 resembles the pelt boards of the previous embodiments however in order to be able to adjust the length of the pelt board 10, there has been included intermediate sections 52 in-between the upper part 14 and the lower part 12. The intermediate sections 52 constitute elliptic cylindrical spacer elements which are non-expandable. The intermediate sections 52 may be made non-expandable since the pelt is most likely to stick to the upper part 14 and the lower part 12. However, the intermediate sections 52 may of course also be made expandable similar to the lower part 12 or the upper part 14. For large pelts, a plurality of intermediate sections 52 may be used. A core connecting element 26 may be used for interconnecting the elongate core element of the lower part 12 and the core extension element of the upper part 14.

[0316] FIG. 12B shows a perspective view of a third embodiment of a pelt board 10 and illustrates how the lower part 12 and the upper part 14 is expanding as shown by the arrows, while the intermediate sections remain constant in circumference.

[0317] FIG. 13 shows a perspective view of a fourth embodiment of a pelt board 10.sup.IV. The present pelt board 56 comprises a number of ribs 56 which contribute to holding the pelt on the pelt board. Further, a number of ventilation holes 40 are present for allowing the pelt to dry quickly. The pelt board 10.sup.IV is of elliptical configuration and the third and fourth wall elements 20 22, having an arched configuration, may overlap the first and second wall elements 16 18 in order to assume the expanded state and the contracted state. The elongated core element has in the present view been omitted. A large opening 58 is present at the bottom end of the pelt board 10.sup.IV for allowing a large amount of dry ventilation air to enter the pelt board 10.sup.IV.

[0318] FIG. 14 shows the bottom end of the lower part 12 of the pelt board. The lower ends of the third wall element 20 and the fourth wall element 22 are fixated by means of cooperating clip-on mechanisms 50 50 such that the third wall element 20 and the fourth wall element 22 cannot move in relation to each other adjacent the lower end of the pelt board. Typically, the pelt does stop a few centimeters above the lower end, otherwise a longer pelt board should be used. Thus, it is not necessary that the third wall element 20 and the fourth wall element 22 are movable adjacent the lower end of the pelt board. A connecting element 60 is used for moving the elongated core element 26 in the longitudinal direction. Also shown are first locking protrusions 62 located on each of the third wall element 20 and fourth wall element 22. Second locking protrusions 64 are located on the connecting element 60. The locking protrusions 62 64 are used to lock the elongated core element 26 in the expanded state. This will be explained further below.

[0319] FIG. 15 shows the lower part 12 of the pelt board when it has been assembled. The connecting element 60 extends from an opening 58 at the lower end of the pelt board. The opening 58 is preferably large for allowing a large flow of air to enter the interior of the pelt board 10 and most preferably the opening 58 defines the greater part of the entire bottom surface of the pelt board 10. The opening 58 typically constitutes the limiting flow surface which determines the amount of air which will flow through the pelt board. A small opening 58 would limit the flow which would cause a less efficient drying of the pelt.

[0320] FIG. 16 shows a perspective close up of the connecting element 60 and the locking principle employed to lock the pelt board in the expanded state. The third and fourth wall elements comprise first locking protrusions 62, whereas the connecting element 60 comprises second locking protrusions 64. The connecting element 60 is flexible in the first radial direction in relation to the third and fourth wall elements. The present locking mechanism is located adjacent the bottom end of the pelt board and together with the friction between the internal moving parts of the pelt board, i.e. the actuator members and the cooperating members, it will eliminate the need of any further locking mechanisms inside the pelt board. The present locking mechanism should be located adjacent the bottom end of the pelt board in order to avoid it being jammed by fatty substances which may come from the pelt. The change from expanded state to contracted state may preferably be made when the bottom end of the elongated core element is attached to the drying unit, e.g. by tilting the pelt board sideways, thereby also taking advantage of the leverage provided by the pelt board for overcoming the friction between the first and second protrusions.

[0321] FIG. 17A shows the locked position of the pelt board. The first locking protrusions 62 are located below the second locking protrusions 64. The first locking protrusion 62 thus prevents the longitudinal movement of the connecting element 60 and thus of the elongated core element.

[0322] FIG. 17B shows the unlocking of the pelt board. By moving the connecting element 60 in the first radial direction, the second locking protrusion 64 is free to move past the first locking protrusion 62.

[0323] FIG. 17C shows the movement from expanded state to contracted state of the unlocked pelt board. By moving the connecting element 60 in the longitudinal direction, such that the second locking protrusion 64 moves past the first locking protrusion 62, the state may be altered from the expanded state to the contracted state.

[0324] FIG. 17D shows the connecting element 60 when the pelt board is in the contracted state. By releasing the connecting element 60, it flexes back to its central relaxed position.

[0325] FIG. 18A shows a perspective view of a further embodiment of a pelt board 10.sup.V when in the contracted state. The pelt board 10.sup.V comprises movable wall elements 16, 16, 16, 18, 18, 18, 20, 22 which together do not cover the complete circumference of the pelt board. In-between the wall elements 16, 16, 16, 18, 18, 18, 20, 22 fixed wall elements 54 are located. When in the contracted state, the wall elements 16, 16, 16, 18, 18, 18, 20, 22 form an even outer surface together with the fixed wall elements 54.

[0326] FIG. 18B shows a perspective view of a further embodiment of a pelt board 10.sup.V when in the expanded state. When in the expanded state, the wall elements 16, 16, 16, 18, 18, 18, 20, 22 move outwardly and form contact surfaces for the pelts. The moving principle of the wall elements 16, 16, 16, 18, 18, 18, 20, 22 have not been shown, however, preferably the same principles are used as for the previous embodiments.

[0327] FIG. 19 shows the pelt board during drying when connected to a drying unit 66. The drying unit 66 has a ventilator 68 and a number of ventilation apertures 70. The ventilator produces a flow of air which is led via the ventilation apertures 70 into the pelt board 10 through the openings 58 at the lower part 12 of the pelt board 10.

[0328] FIG. 20A shows a perspective view of a further embodiment of the pelt board 10.sup.VI, in which the first wall element 16 is integrally joint to the third wall element 20 as indicated by a line of junction 17 and similarly, the second wall element 18 is integrally joint to the fourth wall element 22 through a line of junction 19. The embodiment of the pelt board 10.sup.VI shown in FIGS. 20A-20C presents the further feature of allowing the pelt board to be expanded in two alternative and separate directions; a first direction shown in FIG. 20B as indicated by arrows, according to which expansion the third wall element and the fourth wall element 22 are separated from one another for expanding the pelt board in a first transversal direction and likewise in FIG. 20C, the expansion of the pelt board 10.sup.VI caused by shifting the first wall element 16 and the second wall element 18 relative to one another for expanding the pelt board in a direction indicated by arrows in FIG. 20C, which direction is orthogonal to the direction of expansion shown in FIG. 20B.

[0329] FIGS. 21A and 21B illustrate in greater details the expansion of the pelt board 10.sup.VI in the first transversal direction indicated in FIG. 20B and similarly, in FIGS. 22A and 22B, the expansion in the second transversal direction is illustrated in greater details.

[0330] As is indicated in FIG. 20B and FIG. 20C and likewise in FIGS. 21A and 22A, the expansion in the second transversal direction is accomplished as a further movement of the elongated core element 26 as the movement of the central core element 26 from the position shown in FIG. 20A to the position shown in FIG. 20B accomplishes the expansion of the pelt board in the first transversal direction and further motion of the central core element 26 as indicated in FIG. 20C creates the further expansion in the second transversal direction. By modifying the actuator members 34, 36 and 46, 48 or repositioning them relative to one another, the shifting from the non-expanded state to the full expansion shown in FIG. 20C may be accomplished in a different way by firstly shifting the first and second wall element 16, 18 relative to one another and then afterwards shifting the third and fourth wall elements 18 and 20 relative to one another. In a still further variant of the pelt board 10.sup.VI, the shifting of the pelt board from the non-expanded state to the first or the second expanded states shown in FIGS. 20B and 20C, respectively, may be accomplished selectively by shifting the central core element 26 sidewise in order to contact the one set of actuators 34, 36 shown in FIG. 21B, or alternatively the second set 46, 48 shown in FIG. 22B.

[0331] FIGS. 24-27 illustrate a 3-component embodiment of the pelt board 10.sup.IV, which embodiments constitutes the presently preferred embodiment of the pelt board according to the present invention.

[0332] In FIG. 24, the two shell parts 28 and 29 are shown exposing the exterior surfaces of the two shell parts and in addition, in the left hand part of FIG. 24 exposing the upper ends of the two shell parts, which upper ends serve to catch and fixate a part of the pelt at the head of the pelt. As is evident from the enlarged views of FIG. 24 at the left hand side of FIG. 24, the upper ends are provided with catching claws or teeth serving to fixate the head of the pelt relative to the pelt board.

[0333] In FIG. 25, the two shell parts 28 and 30 are shown in disassembled state exposing the central elongated core element 29 having at its lower end an outwardly protruding part serving to cooperate with a conventional tanning machine and a conventional drying machine.

[0334] In FIGS. 26 and 27, further details illustrated in enlarged views A-G of the pelt board is shown. In A and B, the outer surface of the top part of the pelt board is shown illustrating the longitudinal ridges of the pelt board and edgewise located apertures. In C, the upper end of the shell part 28 is shown illustrating the catching teeth, also shown in FIG. 24. In D, the cam surfaces of the elongated element 29 are shown in greater details and in E, the inner locking elements of the shell part 30 are shown. In F, the lower outwardly extending or protruding element constituting a so-called stubby element is shown, and in G, the locks of the shell part 30 are shown in greater details.

[0335] In general, the above described presently preferred embodiment 10.sup.VI of the pelt board according to the present invention fulfill the following features characteristic of the embodiment. The shell parts 28 and 30 are forcedly guided relative to the elongated core element 29 at a total of six locations along the shell parts, as the forcedly guiding or controlling is established during expansion of as well as during collapsing of the pelt board. The locks of the pelt board serve as a frictional lock preventing collapsing and expansion of the pelt board until an outer force generated by a pelt position on the pelt board activates the lock. The expansion in both transversal directions and likewise the collapsing in both transversal directions is forcedly controlled and guided. The above stubby elements together with the lower end of the shell parts serve to center the pelt board in a drying box or drying machine and provides a stop in the drying box. Further, the stubby element, as distinct from previously used stubby elements serving to catch and lock in the tanning machine and in the drying box or drying machine provides gripping flanges or elements for an improved fixation. For providing individual recordal of the pelt received on a specific pelt board, the pelt board is further provided with an internal holder for receiving an RFID (Radio Frequency Identification Device).

[0336] The shell parts further exhibit the following additional features by providing holes for the drying of the back part of the pelt and providing an increased air through flow as compared to conventional and commercially available pelt boards. In the longitudinal direction of the pelt board, the shell parts are reinforced every 60 mm and transversal bands are further provided every 30 mm. The overall surfaces of the two shell parts prevent vertical shifting of the pelt relative to the pelt board, and the teeth at the upper ends of the two shell parts fixate the upper end, i.e. the head of the pelt relative to the pelt board. The number of teeth for catching the head of the pelt may be constituted by any arbitrary numbers such as 2, 4, 6, 8 or even further teeth as the presently preferred embodiment exhibit a total of four teeth in each of the two shell parts 28 and 30. The assembled pelt board 10.sup.VI shown in FIGS. 24-27 further provide the advantage of collapsing the pelt board in its entire length and allows for machinery operated removal of the pelt from the pelt board. The overall cross section of the pelt board is similar to the geometry of an ellipse in the non-expanded or collapsed state, which provides an improved function as to easy mounting of the pelt and easy removal of the pelt after collapsing the pelt board. The high number of air apertures serving to allow air to circulate through the pelt board and further through the pelt allows for the drying air to be passed from the inside of the pelt board to the outside. The overall opening air layer of the overall transversal opening area of the pelt board is approximately 1200 mm.sup.2 calculated as the open area. In the drying of the pelt, the air is, as is evident from FIGS. 25 and 26 guided inside the pelt board along approximately 60% of the overall length of the pelt board and then transferred to the outer surface of the pelt board through the apertures shown in the enlarged views A and B of FIG. 26.

[0337] FIG. 28A shows a perspective view of a part of a further embodiment of a pelt board 10.sup.VII in its contracted or non-expanded state. The pelt board 10.sup.VII resembles the above described embodiments 10.sup.VI shown in FIGS. 20A, 20B, 20C, 21A, 21B, 22A, 22B, 23A, 23B and 23C. The part of the pelt board 10.sup.VII shown in FIG. 28A constitutes the lower part 12.sup.I of the pelt board, which is shown in FIGS. 31A and 31B, which will be described in greater details below.

[0338] The lower part 12.sup.I of the pelt board 10.sup.VII is composed of a total of three components, namely two identically shaped shell parts 72 and 74 and a central elongated core element 26.

[0339] Each of the shell parts 72 and 74 comprise a major low curvature wall part 22.sup.I and 20.sup.I, respectively, and a minor high curvature wall part 18.sup.I and 16.sup.I, respectively. The major low curvature wall parts 22.sup.I and 20.sup.I are joint to the minor high curvature parts 18.sup.I and 16.sup.I, respectively, through imaginary lines 17.sup.I and 19.sup.I, respectively.

[0340] The embodiment of the pelt board 10.sup.VII shown in FIG. 28A is of a structure, in which the two identically shaped shell parts 72 and 74 in the contracted or non-expanded state shown in FIG. 28A constitute an almost perfectly configured elliptical cross sectional configuration as the longitudinal edges of the oppositely positioned shell parts 72 and 74 join one another in a basically unbroken elliptically cross sectional configuration. The elliptical cross sectional configuration of the pelt board 10.sup.VII shown in FIG. 28A is believed to improve the ability of the pelt board to allow an easy removal of the pelt from the pelt board after the tanning of the pelt as the outer surface of the pelt board 10.sup.VII in its contracted or collapsed state is almost perfectly uniform without any substantive discontinuities.

[0341] In FIG. 28B, the embodiment of the pelt board 10.sup.VII is shown in its expanded state, in which the two shell parts 72 and 74 are caused to be shifted away from one another establishing a gap between the edges of the oppositely positioned shell parts 72 and 74. The shift of the shell parts 72 and 74 away from one another as illustrated in FIG. 28B and indicated by arrows is accomplished by shifting the central elongated core element 26 in a direction also indicated by an arrow inwardly into the interior of the pelt board 10.sup.VII forcing the shell parts 72 and 74 away from one another.

[0342] The separation or the shifting of the shell parts 72 and 74 is accomplished by means of cooperating actuator elements 34 and 36 shown in FIG. 28C identical to the actuator elements 34 and 36 shown in FIG. 21B and described above, the actuator elements 34 being constituted by triangularly shaped bodies extending inwardly from the central part of the major low curvature wall part 22.sup.I of the shell part 72 and likewise from the major low curvature wall part 20.sup.I of the shell part 74, and the central elongated rod 26 is provided with actuator members 36 defining cooperating sloping cam surfaces with which the actuator members 34 cooperate for pushing the shell parts 72 and 74 away from one another to the expanded state shown in FIG. 28C.

[0343] In FIGS. 29A, 29B and 29C, a further embodiment of the pelt board 10.sup.VIII is shown having the same shell parts 72 and 74 as illustrated in FIGS. 28A, 28B and 28C as described above and the central elongated core element 26. Whereas in FIGS. 28B and 28C, the expansion of the pelt board is established as a vertical separation by pushing the shell parts away from one another, the second embodiment shown in FIGS. 29A, 29B and 29C establishes the expansion of the pelt board by shifting the shell parts 72 and 74 sidewise as illustrated in FIG. 29B and as accomplished by the cooperation between actuator members 34.sup.I and 36.sup.I shown in FIG. 29C. To be more precise, in FIG. 29B, the shell part 72 is shifted to the right and similarly, the shell part 74 is shifted to the left relative to the central elongated core elements 26.

[0344] In FIGS. 30A, 30B and 30C, a modified or alternative embodiment of the further embodiment 10.sup.IX shown in FIGS. 29A, 29B and 29C, respectively, is illustrated differing from the above described further embodiment 10.sup.VIII in that the modified embodiment shifts the shell parts 72 and 74 in opposite directions as compared to the shifting shown in FIG. 29B and as illustrated in FIG. 30B, the shell part 72 is shifted to the left and simultaneously, the shell 74 is shifted to the right as accomplished by the modified cooperating actuator members 34.sup.II and 36.sup.II.

[0345] In FIGS. 31A and 31B, the entire pelt board 10.sup.VII is shown having in addition to the lower part 12.sup.I shown in FIG. 28A, an upper part 14 constituting a geometrical extension and continuation of the lower part 12.sup.I and having a tapering configuration. The upper part 14.sup.I also comprises two shell parts 28.sup.I and 30.sup.I which, like the shell parts 72 and 74 of the lower part 12, are caused to be separated similar to the separation of the shell parts 72 and 74 of the embodiment 10.sup.VII described above with reference to FIGS. 28A, 28B and 28C. It is readily understood that the separation of the two shell parts 28.sup.I and 30.sup.I of the upper part 28.sup.I is accomplished in the same manner as described above with reference to FIGS. 28A, 28B and 28C in relation to the lower part 12.sup.I of the pelt board 10.sup.VII, and like the further embodiment 10.sup.VIII shown in FIGS. 29A, 29B and 29C and the modified embodiment 10.sup.IX shown in FIGS. 30A, 30B and 30C, the complete pelt board 10.sup.VII shown in FIGS. 31A and 31B may be modified into establishing the sidewise expansion described above with reference to FIGS. 29A, 29B and 29C and also FIGS. 30A, 30B and 30C.

[0346] FIG. 32 and FIG. 33 illustrate in greater details a further embodiment 10.sup.X of the pelt board according to the present invention, which embodiment exhibits the highly advantageous feature of being composed of no more than three components, namely two identically shaped shell parts 72.sup.I and 74.sup.I and the central core element 36. The shell parts 72.sup.I and 74.sup.I integrally comprise the shell parts 72, 72 and 28.sup.I, 30, respectively, of the embodiment 10.sup.VII of the pelt board, as the shell parts 72 and 72 and similarly the shell parts 28.sup.I and 30.sup.I of the lower and upper parts 12.sup.I and 14.sup.I, respectively, of the pelt board 10.sup.VII are constituted by a single integral component 72.sup.I and 74.sup.I, respectively. Likewise, the central elongated core element serving to shift in a forced manner the shell parts 72.sup.I and 74I from the contracted or non-expanded state to the expanded state and vice versa serve to engage with the actuator elements of the shell parts 72.sup.I and 74.sup.I.

[0347] FIG. 34 shows a perspective view of a pelt board 10.sup.II which is accommodating a pelt 76. The pelt 76 is stretched on the board and fastened in the stretched position by a clip 94 adjacent the tail part of the pelt 76. The clip 94 is positioned above ribs 38 of the pelt board 10.sup.II which ribs 38 interacts with the clip 94 for retaining the pelt 76 on the pelt board 10.sup.II.

[0348] FIG. 35A shows a perspective view of the clip 94 of the previous figure. The clip 94 constitutes a strip of plastic material which is clamped onto the pelt 76 on the board 10.sup.II. The clip 94 is straight when not applied to the pelt board. The clip 94 comprise a pair of opposing rigid fastening sections 96 96, a pair of opposing flexible sections 98 98 each connected to a fastening section and a rigid section 90 interconnecting the flexible sections 98 98. The flexible sections 98 98 may easily be bent such that the fastening sections 96 96 meet about the pelt board 10.sup.II. The fastening sections 96 96 may be joined together by a screw or similar via a hole 96. The combination of rigid sections and flexible sections allow the clip 94 to assume a substantially uniform fixation pressure on the pelt 76. The clip 94 comprise gripping members 100 having a small spacing in-between themselves and the flexible section 98 98 of the clip 94 comprise a larger spacing 92 between gripping members 100 in order to allow the flexible sections 98 98 to be easily bent.

[0349] FIG. 35B shows a close-up view of the clip 94. The clip 94 comprises a plurality of gripping members 100 intended to face the pelt on the pelt board. The gripping members 100 define a small distance between themselves allowing hair to pass in between the gripping members 100. Each of the gripping members 100 have a T-shape, i.e. a short and slender element extending outwardly from the clip 94 and a contact element extending parallel to the clip 94 at the outward end of the short and slender element and intended to be facing the pelt board 10.sup.II.

[0350] FIG. 35C shows a close-up view of the clip 94 and the pelt 76. The clip 94 comprises gripping members 100 having the T-shape facing the pelt board 10.sup.II. The T-shape of the gripping members 100 allow the gripping members 100 to penetrate the hair 102 of the pelt 76 such that the inwardly oriented fixation pressure generated by the clip 94 is applied to the leather of the pelt 76 and not the hair of the pelt 76. Thus, any deformation of the hair 102 of the pelt is avoided.

[0351] FIG. 35D shows a close-up view of the clip 94 at the flexible section 98 of the clip 94 comprising rounded gripping members 100 and spacing 92 between the gripping members to prevent squeezing of the hair 102 of the pelt 76 when the flexible section 98 are bend.

[0352] FIG. 36 is a view similar to the view of FIG. 34 illustrating the pelt 76 onto which a fixation bag 106 is applied prior to the application of the strip onto the pelt 76.

[0353] Although the present invention has above been described with reference to several advantageous embodiments, it would be evident to a person having ordinary skill in the art that numerous modifications and variants of the above technical disclosure may be deduced without deviating from the overall inventive concept as defined in the appending claims, and it would be evident to a person having ordinary skill in the art to deduce variants of the above described advantageous embodiments by combining the embodiments, i.e. by including features of one embodiment into a different embodiment.
