DETAILED DESCRIPTION OF THE INVENTION
(22) In the following, description of the invention, the same reference signs are used for identical and identically functioning elements.
(23) FIGS. 1 to 4 respectively show embodiments of a musical instrument stand 1 respectively having three (FIG. 1), four (FIGS. 2 and 3) or only one (FIG. 4) pair of support elements 20a, 20b according to the invention with a respectively identical functionality.
(24) Musical instrument stand 1 depicted in FIG. 1 consists of a rack 10 and a contact bracket 14 connected to it. Rack 10 has a support frame 11, which is formed by two parallel running support rails 12a, 12b, and crossbars 19 connecting support rails 12a, 12b. Support elements 20a or 20b are respectively pushed onto support rails 12a, 12b (see FIG. 4), wherein all three pairs of a total of six identical support elements 20a, 20b are mounted in a first support arrangement S1 on support rails 12a or 12b FIG. 1. Support elements 20a, 20b can have a one-piece or multi-piece design, particularly consisting of multiple materials. Thus, e.g. up to three similar guitars can be held in musical instrument stand 1. Support elements 20a, 20b have a shell-like design and serve to support the body of a musical instrument 2, for example an electric or acoustic guitar or a bass guitar. Mounted support elements 20a, 20b have the same length, wherein support elements 20a, 20b are capable of being independently mounted and are interchangeable. Support elements 20a, 20b of different lengths can be mounted. Contact bracket 14 is connected to support frame 11 via two swivel joints 18. Contact bracket 14 comprises two lateral support arms 16, 17, which are connected to a contact rail 15 running parallel to support rails 12a, 12b via connecting elements. Three contact elements 30 are pushed onto contact rail 15, which form contact surfaces 31 with lateral contact surfaces 32, 33 for resting the neck of a musical instrument 2 supported in a support element 20a, 20b. Oil a rear side, support frame 11 has base elements 10 in order to be able to set musical instrument stand 1 up in a folded position.
(25) The front two pairs of a total of four pairs of support elements 20a, 20b are mounted in a second support arrangement S2, while the rear two pairs are mounted in a first support arrangement S1 in the embodiment of musical instrument stand 1 depicted in FIG. 2. Support elements 20a, 20b can be switched back and forth by repositioning them between both support arrangements S1, S2. This can be done either by interchanging both support elements 20a and 20b of a pair, i.e. by mounting support elements 20a and 20b on respectively other support rail 12b or 12a, or through a reverse assembly of each support element 20a, 20b onto respective support rail 12a or 12b, i.e. by pushing on support element 20a or 20b that is rotated by 180. All eight support elements 20a, 20b have the same length in FIG. 2.
(26) Each support element 20a, 20b has a center support snake 210a or 210b and lateral support surfaces 220a, 220b or 230a, 230b. Support surfaces 210a, 210b run respectively diagonally to support rails 12a or 12b and, in doing so, define bearing planes E tilted towards each other (see FIGS. 5, 6, 7a, and 7b). Two support surfaces 210a, 210b are respectively aligned towards each other, i.e. in a V-shape, in first support arrangement S1. In a second support arrangement S2, support surfaces 210a, 210b are respectively aligned away from each other, i.e. in an A-shape. First support arrangement S1 is particularly suitable for supporting a guitar with a round body shape, while second support arrangement S2 is particularly suitable for supporting a guitar with a V-shaped body. Lateral support surfaces 220a, 220b, 230a, 230b are formed by support edges 27 that are formed by support elements 20a, 20b, which protrude with respect to bearing plane E or support surface 210a, 210b. Lateral support surfaces 220a, 220b, 230a, 230b prevent rested musical instruments 2 from being able to turn sideways in support elements 20a, 20b. Thus, musical instruments 2 are also unable to bump into each other and become damaged.
(27) An embodiment corresponding to FIGS. 1 and 2 having a total of four pairs of support elements 20a, 20b is depicted in FIG. 3, wherein the from two pairs are shorter, e.g. 120 mm long, than both rear pairs, which are, e.g. 180 mm long. Shorter, or narrower, support elements 20a, 20b are particularly suitable for supporting electric guitars or bass guitars, while longer, or wider, support elements 20a, 20b are particularly suitable for acoustic guitars, which typically have a deeper, or wider, body. Both rear contact elements 30 are designed to match this with a double indentation having an intermediate center protrusion, which have suitable contact surfaces 31 and lateral contact surfaces 32, 33 for the neck of an acoustic guitar in respectively one of the two possible resting positions.
(28) The assembly process or the adjustment of a musical instrument stand 1 can, be found in FIG. 4. Support rails 12a, 12b are designed as aluminum profiles having a non-rotationally symmetrical cross-section shape Q1in this case, as square hollow profileswhich are inserted into passage openings 190 in crossbars 19 and fastened with screws on the front. Crossbars 19 are preferably made of a plastic, such polyamide, for example of PA6, although they could also consist of metal, e.g. aluminum. Stand elements 191 are inserted from the bottom and base elements 110 are screwed on from behind. Analogous to support rails 12a, 12b, contact rail 15 made of an aluminum profile having a square cross-section shape Q2 is screwed to support frames 16 and 17 via connecting elements. Support elements 20a, 20b and support elements 30 are pushed on in the longitudinal direction of support rails 12a, 12b or of contact rail 15. Alternatively, they can also be clamped onto support rails 12a, 12b from the top or laterally. For this purpose, support elements 20a, 20b and contact elements 30 have mounting recesses 24 or/and 30, which are matched to cross-section shape Q1 or Q2 or positively correspond to them. Support elements 20a, 20b and contact elements 30 can be mounted through mounting recesses 24 or 34 on support rails 12a, 12b or contact rail 15 in an orientation set by means of rotation such that they are secured from turning. Additional mounting elements can therefore be eliminated. FIG. 4 clearly illustrates that support elements 20a, 20b could be respectively inversely pushed onto support rails 12a, 12b or are interchangeable with each other in order to be positioned in either first support arrangement S1 or second support arrangement S2. This provides great flexibility when using the musical instrument stand, particularly adaptability for different types of musical instruments 2, especially guitars having round or V-shaped bodies.
(29) Embodiments of a support element 20a according to the invention is depicted in FIGS. 5 and 6, which would have to be respectively inversely depicted for a support element 20b, wherein two embodiments of a support element 20a are depicted in FIG. 5 with respectively different lengths. Support element 20a has a three-piece design with a center element 21a and two side elements 22a, 23a. Side elements 22a, 22b are made from a thermoplastic, such as polyamide, e.g. PA 6, so that they are bend-resistant and torsion-resistant, while center element 21a is made of a thermoplastic elastomer (TPE) that is soft and elastic. Thus, side elements 22a, 23a are made from a different material, which is particularly more rigid, than center element 21a. Side elements 22a, 23a respectively have a basic triangular form, wherein mounting recess 24 is designed with respect to a center axis M in the area of a lower corner. Mounting recess 24 is designed as a passage opening matched to cross-section shape Q1 of support rails 12a, 12b and enables side elements 22a, 22b to be positively mounted on a support rail 12a, 12b so that they are secured against rotation. Center element 21a is designed as a hollow body 25, wherein support surface 210a or diagonal support surface E defined by this is designed on an outer side 26. Support surface 210a passes laterally to side support surfaces 220a or 230b, which are designed through inner side surfaces 272 of crescent-shaped support edges 27. Side elements 22a, 23b can be attached laterally to or inserted into center element 21a, wherein a positive connection between both side elements 22a, 23a and center element 21a that is secured against rotation is achieved by surrounding stepped edge profiles 210 or 220. Bearing plane E is rotated by 45 with respect to symmetrical axes A of mounting recess 24 or cross-section shape Q1. Thus, bearing planes E run rotated towards each other in first and second support arrangement S1 or S2 (see FIGS. 7a and 7b).
(30) A musical instrument stand 1 with a musical instrument 2 rested therein is depicted in FIGS. 7a and 7b. In FIG. 7a, a guitar having a round body is supported by support elements 20a, 20b mounted in first support arrangement S1 and leaned against contact element 30, while in FIG. 7b a guitar having a V-shaped body is supported by identical support elements 20a, 20b mounted in second support arrangement S2.
(31) A swivel joint 18 of rack 10 of a musical instrument stand 1 is depicted in FIGS. 8a and 8b, wherein swivel joint 18 is equipped with a locking mechanism 50. A joint head of contact bracket 14, which is made for example from a fiber-reinforced plastic and connected to support arm 16 or 17, has a first engagement device 141 in the form of two locking grooves designed along the peripheral contour. In first end position P1 of contact bracket 14 (FIG. 8a), support arm 16 is pivoted in a vertical direction, i.e. folded out. In second end position P2 of contact bracket 14, support arm 16 is pivoted in an essentially horizontal direction, i.e. collapsed or folded, and runs essentially parallel to crossbar 19. A bending element 51 is connected to support frame 11, which is cast on as a plastic bending element on an inner side of support frame 11 and has a degree of bending freedom in the direction of pivot axis B (from the bottom upwards in FIGS. 8a and 8b). Bending element 51 has a second engagement device 53 in the form of a locking tab designed to fit first engagement device 141, which respectively engages in another of both first engagement devices 141 in first or second end positions P1 or P2 in order to lock contact bracket 14 in the respective position. A spring 53 supported on an inner side of support frame 11 engages on the bottom of bending element 51 and in a groove 56 and impinges second engagement device 53 with a locking spring tension in the direction of first engagement device 141. Spring 53 is designed as a wire clip, for example with a diameter of 3 mm, having two pairs of contact tongues 54 and a crossbar 55 connecting both pairs of contact tongues 54, which snaps into groove 56 of bending element 51. Axis 180 of swivel joint 18 is inserted laterally in axis openings of support frame 11, wherein contact tongue ends 57 engage in a circumferential groove 181 of hollow axis 180 in order to secure it axially from slipping out. The assembly process of swivel joint 18 with locking mechanism 50 is depicted through arrows in FIG. 9, wherein spring 53 is first inserted into a mounting opening of crossbar 19 and contact bracket 14 from the top and then axis 180 is pushed in laterally. Spring 53 and thus bending element 51 is pre-tensioned in an installed state by bending contact tongue pairs 54 slightly upwards. A musical instrument stand 1 is depicted in FIG. 10 with contact bracket locked in second end position P2. In position P2, musical instrument stand 1 can, for example, be transported practically, folded up to save space and set up particularly on base elements 110. In addition, two or four floor rollers on rack 10 can be provisioned for pulling or pushing musical instrument stand 1.
(32) An embodiment of musical instrument stand 1 is depicted in FIGS. 11, 12, and 13 with telescopic support arms 16, 17. Support arms 16, 17 comprise respectively one out support arm profile 41 and one inner support arm profile 42, which are arranged so that they can slide in each other and be set relative to each other in a telescoped or collapsed position via locking mechanisms 41. A telescoped position is depicted in FIG. 11. Telescopic support arms 16, 17 enable a smaller upright dimension or packing size of musical instrument stand 1, as is seen in the comparison of FIGS. 10 and 13. For example, the overall length of support arms 16, 17 can be shortened by approx. 20 to 35 cm when musical instrument stand 1 is folded up.
(33) An alternative embodiment of a support element 20a or 20b is depicted in FIGS. 14a and 14b, which has an inner support element 28 designed to be bend and torsion-resistant with a mounting recess 24 matched to cross-section shape Q1 of support rail 12a, 12b. Inner support element 28 can be assembled in various supporting arrangements S1 and S2 on support rails 12a or 12b, as previously described in conjunction with FIGS. 1 to 4. A preferably soft elastic cover element 29 designed as one-piece can be positively attached or placed on inner support element 28, preferably on both sides, in order to support a musical instrument 2. Fasteners are provisioned on the back of cover element 29, which are adapted to inner support element 28. Cover element 29 has a lateral rail recess 290 to enable support rail 12a, 12b to be ted through in the assembled state.
(34) A musical instrument stand 1 is depicted in FIG. 15 with four pairs of support elements 20a, 20b of a varying, length, which are assembled in two different support arrangements S1 and S2 in order to receive a total of three different types of musical instruments 2.
(35) A musical instrument stand 1 or its assembly (see arrow in FIG. 16a) is depicted in FIGS. 16a and 16b with five pairs of support elements 20a, 20b, which functionally correspond to support elements 20a, 20b described in conjunction with FIGS. 1 to 4 but have an alternative form. Support elements 20a, 20b have dual curved hearing surfaces 210a, 210b, wherein the curvature is vertical to support rails 12a, 12b outwards (convex) and parallel to the direction of support rails 12a, 12b inwards (concave). This produces a smaller bearing surface of a musical instrument 2 on support elements 20a, 20b. Support elements 20a, 20b have a one-piece design and have a formed mounting recess 24 on their bottom side, which corresponds to cross-section shape Q1 of support rails 12a, 12b.
(36) A musical instrument stand 1 according to the invention has the advantage of being able to be used more flexibly and therefore being easily adaptable to the individual needs of the musician, particularly in order to be able to safely hold various types of musical instruments 2, preferably guitars with round and V-shaped bodies.
(37) At this point, it should be indicated that all aspects of the invention described above, viewed separately on their own and in each combination, particularly the details depicted in the drawings, are claimed as essential for the invention. Specialists are familiar with changes thereof.
