[0079] In a perspective illustration, FIG. 1 represents a drive device 1 in an exemplary arrangement. The drive device 1 includes a straight planar underside 25 of a lower housing part 2. Circumferential roundings 8 laterally adjoin the lower housing part 2, which roundings merge for example into straight lateral sections 9, which are configured to be essentially offset by 90 to the underside 25. FIG. 1 clearly illustrates that the drive device does not include any protruding housing parts. Border areas 15, which surround the underside 25, adjoin the roundings 8 via radii in the corner areas. The area of the roundings 8 may simultaneously also include a light band 3, preferably a circumferential one. Such a light band 3, which is able to effect different lighting designs, which translates into different illumination colours, is achieved by means of control boards 32, 33, which are contained within the drive device 1. A drive track 4 is disposed at a frontal side 17 of the drive unit 1.
[0080] FIG. 2 shows an upper housing part 18, which is connected to the lower housing part 2 by means of a plug-in connection. A transitioning area 11, configured in a curved form and extending as far as to the area of a housing upper side 7, may adjoin the lateral sections 9. In this exemplary embodiment, the housing upper side 7 may be configured as well by means of a part of a mounting base 5 with a connected adjoining area 6 for the drive track 4. The form design of the entire housing of the drive device 1 clearly shows that in particular also dominant, respectively protruding housing parts or the like have been foregone for the upper housing part 18, with the intention to reduce manufacturing costs. The adjoining area 6 includes an extension 10, which allows for a connection to the drive track 4 at a frontal side 17 of the drive device 1, without having to configure here any further protruding housing parts, as known from the state-of-the-art.
[0081] In the preferred exemplary embodiment according to FIG. 3, the housing upper side 7 does not include any additional structural components, such as the mounting base 5 or the adjoining area 6. In this case, the housing upper side 7 is configured to be straight and, in the area of an arresting member 102, is interrupted by means of attachment bores 16 and 39 as well as attachments 20. Furthermore, the upper housing part 18 is different in that a service access 12 is represented at the frontal side opposite the extension 10.
[0082] The service access 12 includes plug-in connections 14 and a mains power supply 13. The service access 12 is closed by means of a non-illustrated removable covering.
[0083] FIG. 3 clearly shows once more, that no protruding structural components or the like are located neither at the housing upper side 7 nor at the underside 25. Herein, the housing of the drive device 1 is distinguished by means of a flat, slender housing in a harmonious shape with lateral roundings. The connection of the drive track 4 realized at the frontal side 17 does not interfere with the entire structure of the housing.
[0084] FIG. 5 shows a sectional illustration transversely through the drive device 1. In this case, a motor 26 can be seen, which is flanged to a gearbox 27 and is secured by means of a motor attachment 24. An electrical motor connector 21 supplies the motor with electrical energy from the control system 123. The approach and thereby the ingenious incorporation of two motors 26, 28 at the gearbox 27 is again illustrated in the longitudinal section of FIG. 6. In this case, the motor 26 is disposed at a motor connector 58 via the motor attachment 24 and the motor 28 is likewise connected via a separate motor attachment 24 to the gearbox 27 via a motor connector 57.
[0085] FIG. 6 reveals the arrangement of the motors 26 and 28, which can be employed selectively or together with the gearbox 27, depending on the power requirements.
[0086] FIG. 7 underlines this circumstance, which shows a view into the upper housing part 18, wherein the gearbox 27 with the motors 26 and 28 connected thereto is illustrated in the upper housing part 18. Furthermore, a transformer 30 is provided for the control boards 32 and 33. A cut-out for the ingress of the drive track 4 is located at the frontal side 17 of the upper housing part 18. The gearbox has been immobilized via attachments 66 within the upper housing part 18. In the same manner, the other structural components have been also clipped into the assigned areas of the upper housing part 18. This type of mounting, as well as the placement of the structural components, can be seen in FIG. 8. Unlike FIG. 7, the drive track 4 is not connected. At the head side, the drive track 5 comprises a transmitting part with a linking part 34, which part has been separated from the part, referred to as the driving part, of the gearbox 27. The linking part 34 includes a linking plate 40, which serves for the direct connection to the drive track 4. By means of guiding webs 35, a precise-fitting placement of the transmitting part in the gearbox 27 is realized via a linking part reception 38. The guiding webs 35 are pushed into guiding receptions 37. The proper seating of the transmitting part may also be additionally assisted by means of at least one projection 36 provided at the linking part 34, which projection engages into a complementary recess within the gearbox housing.
[0087] FIG. 9, which illustrates a rotation by 180 of both the drive track 4 and the upper housing part 18, reveals that the linking part 34 also includes attachment bores 44 as well as 41. It is via the bores 44 that a fixation of the transmitting part within the drive device 1 is furthermore assisted in conjunction with the bores 16, 39 within the housing upper side 7. In this case, the linking part 34 has been manufactured as a moulded part, for example made from plastic material or from metal, and includes an axis reception 56.
[0088] In FIG. 10, an axis 60 has been inserted into the axis reception 56, and likewise a drive wheel 61 for a force transmitting means 46, as well as transmitting wheel 48 which are likewise located above the axis 60. A covering 42 covers a portion of the transmitting wheel 48, wherein also an axis bearing for the axis 60 is provided at the end side within the covering 42. The covering 42 is attached via screw connections 43, which penetrate into the attachment points 41 located there below.
[0089] While in FIG. 10 the view is directed to the underside of the drive track 4, in FIG. 11, the same embodiment is represented, just in a view onto the opening side of the drive track 4, in which Figure also the force transmitting means 46 are revealed. This illustration reveals that the end of the drive track 4 abuts against an abutment web 45 of the linking part 34. Furthermore, struts 47 are illustrated within the drive track 4 for stabilizing the linking part 34.
[0090] FIG. 12 shows a gearbox 27, to which two motors 26, 28 are flanged. Furthermore, this illustration very clearly reveals the configuration of the linking part reception 38 within the gearbox. FIG. 13 represents how the transmitting part with the linking part 34 is located within the configuration of the linking part reception 38 and how the drive track 4 disposed thereat is located within the gearbox 27. The linking part 34 is connected to the gearbox housing 54 via the connecting screws 49. This configuration is likewise revealed in the illustration according to FIG. 14, in which the drive track 4 with the gearbox 27 and the motors 26, 28 have performed a rotation about 180. The covering 42 meets a top cover 74 of the rest of the housing, wherein a parting line 50 is created in order to be able to realize a simple mounting of the driving part to and dismounting from the transmitting part. So that a precise fitting alignment is possible when joining the driving part and the transmitting part, a projection 51 is provided both in the area of the covering 42 and of the top cover 74. So that in addition to the attachments 66 represented in FIG. 7 further attachments of the gearbox 27 can be embodied, attachment bores 53 are contained within the gearbox 27, through which the connecting elements pass, which are inserted into the attachments 20. Subsequently, a covering 102 is employed to be placed onto the projections 51 and to be simultaneously immobilized at the housing upper side 7 by means of the attachments 20 in conjunction with the attachment bores 53.
[0091] FIG. 15 represents once more the arrangement of the driving part of the gearbox 27 in an individual illustration. Herein, the linking part reception 38 with the guiding receptions 37 can be seen. The motors 26 and 28 are disposed at the motor connectors 57 and 56, which are conformed to the gearbox housing 54. The two motors 26, 28 are supplied each with electrical energy from the control system 123 via the respective electrical motor connectors 21.
[0092] FIG. 16 shows the gearbox housing 54 in conjunction with the linking plate 40 for the drive track 4. It is revealed herein that the axis receptions 55 and 56 are conformed into the bottom 129 of the gearbox housing 54.
[0093] Another preferred embodiment of the configuration of the transmitting part is represented in FIG. 17. In this case, the configuration of the connecting part 59 is represented in a modified embodiment. A spur gearing 32, which serves for supporting the transmitting wheel 48, is located on the axis 6. If the transmitting wheel 48 and the drive track 4 are removed, the illustration of FIG. 18 represents a view onto the redirection roller in the shape of a driving wheel 61. In this case, the force transmitting means 46 is wrapped around the driving wheel 61. The connecting part 59 is configured in that it includes the area for connecting to the gearbox 27 and moreover also contains the linking plate 40 for connecting to the drive track 4. In this case, projecting attachments 18, which, when joining with the drive track 4, guarantee a proper seating with the linking plate 40, are provided at the linking plate 40. In this case, the drive track 4 abuts against locating webs 45 at the end-side, in which also the bores 44 are contained.
[0094] The operation of joining the transmitting part to the drive track 4 and the driving part to the gearbox 27 is represented in FIG. 19. By placing the connecting part 59 into the linking part reception 38, the cooperation of the transmitting wheel 48 with the driving wheel 86 is illustrated. The gearbox 27 is inserted into the upper housing part 18 through the exterior attachments 66 and immobilized. Also this configuration of the transmitting part allows for inserting the drive device 1 without any problem into the extension 10 of the housing, as can be seen in FIG. 20.
[0095] The illustration of FIG. 21 represents the cooperation of the linking plate 40 with the gearbox 27 in a separate embodiment. In this exemplary embodiment, only one motor 26 has been flanged via the motor attachment 24. Hereby, the locating webs 45 reach abutment at the exit side 72 of the gearbox 27. The holding elements 63, which are configured to protrude and include an undercut 68, are represented within the linking plate 40. FIG. 22 represents the manner, in which the holding elements 63 engage into the section-wise illustrated through-openings 71. In this case, the illustrated holding elements 63 are inserted into the through-openings 71 and are displaced into the direction of the locating web 45. With the intention to achieve a precise-fitting positioning of the drive track 4, on the one hand a projection 141 is provided within a through-opening 70, and on the other hand, the strut 47 is provided in a further cut-out for stabilizing the position. The holding projections 63, which, after having placed the drive track 4, simultaneously reach an interlocking position following the displacement in the direction of the locating web 45, engage on each side into the through-openings 71, which are configured as oblong holes. Thereby, the oblong holes 71 together with the holding elements 63 produce a non-positive and positive connection between the linking plate 40 and the drive track 4. This arrangement is illustrated in FIG. 23 in a complete illustration of the embodiment of the drive track 4.
[0096] FIG. 24 represents a modified embodiment of a gearbox 83. In this case, the connection of the motors 28 and 26 is maintained in the above-described manner via the motor connectors 57 and 58. The gearbox 83 has a frontal-side exit 72 and presents an essentially rectangular shape, which is characterized by a sidewall 73 and on the opposite side by the extension 65. The extension 65 is located in the area of the motor connectors 57, 58 and includes the bearing of a worm 79 in the already described manner. The gearbox 83 is closed by means of connecting screws 49, wherein axes bearings for the axis 60 and an axis 76 are provided within the top cover 75 thereof.
[0097] The perspective illustration according to FIG. 24 reveals the connecting side 72 of the gearbox 83. It is via the connecting side 72, that the force transmitting means 46 is introduced into the gearbox 83 and redirected therein and again led to the outside.
[0098] The gearbox 83 illustrated in the FIGS. 25 and 26, is illustrated according to FIG. 26 as being attached to the mounting base 5. An adjoining area 6, in which the bores 78 are provided, which serve for the attachment to the drive track 4, is illustrated on one side at the mounting base 5. A drive housing 80, which is configured for the gearbox 83, is represented in FIG. 27. In this case, starting at the base bottom 84, which on the exterior has a smooth straight configuration, sidewalls 85 and 73 are provided. A frontal wall 140 is provided opposite the open exit side 72. The worm 79 is illustrated in the extension 65 via worm bearings 81. An opening 82, through which the teeth system of the worm 79 passes for reaching an operative connection with a worm wheel 110, is provided in the range of the worm 79. In the sectional illustration B-B according to FIG. 30, the cooperation of the structural gearbox components is revealed. The worm wheel 100 is supported on the axis 76 and, via an extension, includes a spur gearing 88, on which the driving wheel 86 is seated. The transmitting wheel 48, which is supported on the axis 60, is in operative connection with the driving wheel 86. Via the spur gearing 62, the driving wheel 61 for the force transmitting means 46 is located below the transmitting wheel 48. As can be seen furthermore in this illustration, the axis 76 and 60, in the shape of spindle inserts, are inserted into the base bottom 83 of the housing.
[0099] In a view onto the gearbox 83 without the covering according to FIG. 28, this arrangement is once more revealed. In this case, the driving wheel 86 is larger than the transmitting wheel 48; however, this can be configured differently according to the embodiment.
[0100] In the sectional illustration A-A according to FIG. 29, in particular the bearing of the worm 79 can be seen on the left side via an end-side bearing 93, which is configured as an axis reception and includes a spindle insert 90, which is connected to the rotor axis 90 of the motor 28. A ball bearing 97 is illustrated on the right side. Another spindle insert 96 engages into an axis reception 97 and is connected to the rotor axis 89 of the motor 26. At the end sides, the rotor axes 89 are supported in the motors 26, 28 in motor extensions of the motor housing 91. This arrangement can be seen once more in a detailed illustration of FIG. 31. The end of the worm 79 includes an axis reception 98, into which the spindle insert 92 engages on one side. In this case, the axis reception is supported within a bearing 97. Moreover, the spindle insert 92 is supported in a rotor bearing 93.
[0101] The perspective illustration according to FIG. 32 represents a portion of the drive device 1 and, at the frontal side 17, the connection to the drive track 4 via attachment means. The motor 26 is visible within the drive device 1. The force transmitting means 46 is guided within the drive track 4 and is redirected within the gearbox 83 via the driving wheel 61. A carriage 109, which is connected to a catch element 110 and displaceably supported within the drive track 4, is in operational connection with the force transmitting means 46. An arm assembly 120 is linked via the catch element 110. In this exemplary embodiment, the mounting base 5 is extended by an adjoining area 6. With the intention to achieve an attachment of the drive track 4 to the adjoining area 6, attachment means 105 are mounted laterally to the sidewalls 107 of the drive track 4. In the exemplary embodiment, the attachment means 105 are configured as angularly-shaped brackets, which include a base branch 108 and adjoined thereto a distancing branch. At the end of the distancing branch, a retaining claw 103 is provided, which overlaps the drive track 4 at least partially. This may be configured for example in that the retaining claw 103 engages into a groove 106 of the drive track 4. The attaching means 105 are immobilized at the adjoining area 6 via the attachments 111. In this case, the attachments 111 are embodied as screws. Thus, pre-mounting in the factory is possible, namely in that the attachment means 105 can be already pre-mounted. At the construction site, it is thereby possible to push the ends of the drive track 4 between the lateral attachment means 105. This illustration reveals as well that the drive track 4 is placed at the frontal side 17 of the drive device 1.
[0102] In a particular embodiment, the gearbox systems 27 and 83 may be equipped with a measuring device for counting the revolutions. For this purpose, FIG. 33 represents one possible example, in which a measuring wheel 87 is employed, which is connected to the worm wheel. In this case, the measuring wheel 87 includes projections 114 next to gaps 113. Such a measuring device consists for example of an incremental encoder, which counts the revolutions based on the different increments. Counting said increments is performed by means of a light barrier 112. In addition to said preferred embodiment, it is possible to embody other configurations of a measuring device as well, in particular using hall generators and rotating magnets.
[0103] The connection of the drive device 1 to the drive track 4, both to the casing area and to a ceiling or the like, can be seen in FIG. 34. In this case, in the casing area, an attachment 122 has been used, which is able to perform a rotational movement for compensating tolerances. The drive track 4 has a suspension 121, which by means of hanging means allows for building a precise fitting suspension and alignment of the entire structure. The same applies to the suspension 119, which is configured in the exemplary embodiment at the mounting base 5.
[0104] The drive device 1 described in the different embodiments may experience a further improvement by means of the light band 3 at the border area of the housing. In a preferred embodiment, it is possible to additionally enlarge, respectively to complete the drive track 4 with lateral drive track lateral parts 115. So to say in continuing the exemplary embodiment of the light band 3, said drive track lateral parts 115 may be embodied on each side by means of a light band 116.
[0105] FIG. 35 shows the embodiment of FIG. 36 from the backside and reveals that the design of the drive track lateral parts 115 is realized in continuation of the design of the drive unit 1. In a modified form, it is possible that, with a larger space requirement within the drive device 1, the upper housing part 18 is provided with an extension 118. Said extension 118 retracts with regard to the exterior edges and likewise continues as an extension 118 into the area of the drive track lateral parts 115.
[0106] FIG. 38 is intended to reveal that the drive track 4 can be also accommodated in a different way within the drive housing and attached by means of attachments 124. In this case, the drive track 4 enters the upper housing part 18 via the extension 10.
[0107] In a particular embodiment, the lower housing part 2 may be configured in that it simultaneously serves as an illumination apparatus. In this case, connecting receptions 126 can be formed for example into a border 29 of the upper housing part 18, which receptions cooperate with connecting projections 125 of an illumination unit 132, and may consist for example of a flat straight bottom 128, at which the lateral connecting projections 125 are disposed. A radiation unit 127 for emitting light rays is provided at least at one side. In this case, preferably the entire bottom 128 may be provided with a light-enforcing respectively light-reflecting coating or the like. The radiation unit 127 is supplied with electrical energy by means of the control system 123 of the drive device 1. The exterior termination may be formed for example by a covering 129 according to FIG. 40. The latter is connected to the lower housing part 2 by means of said projections 130 and is removable.
[0108] A particular embodiment of the illumination unit 132 may be seen in FIGS. 41, 42. The illumination unit 132 is illustrated in a perspective illustration with a straight planar radiation surface 131. A communications field 133 is illustrated within the radiation surface 131. The radiation surface 131 is delimited by a lateral edge 135. Electrical energy is supplied from the control system 123 to the illumination unit 132 via an electric connection 134. In addition to displays, the communications field 133 may include electronic touch fields.
[0109] The basic structure of the illumination unit 132 is represented in an exploded illustration in FIG. 42. In the lower part of the illustration, the radiation surface 131 is illustrated with a lateral circumferential border 135. The communications field 133 is illustrated within the radiation surface 131. In a preferred embodiment, it is possible that a reflector be provided behind the radiation surface 131. Said reflector 136 is terminated by means of a circumferential frame 137. Laterally at the frame 137, at least one radiation unit 127 may be affixed, in which the light-emitting diodes are accommodated. By supplying electrical voltage, said non-illustrated light-emitting diodes generate light, which effects a homogenous lighting of the radiation surface 131 by means of the configured reflector 136.
[0110] In a further preferred embodiment, it is possible to insert a light guide 139 behind the border 135 of the radiation surface 131. Said light guide 139 may be charged with electric voltage from the radiation unit 127. However, it is likewise possible to employ here an additional radiation unit 138. The light guide 139 is just located in the exterior area of the border 135, wherein the border 135, just like the entire radiation surface 131, may be transparent, respectively made from a translucent plastic material. When the light guide 139 is energized, light is emitted. The light guide 139 will be employed to illuminate the border area of the illumination unit 132. With the appropriate selection of light-emitting diodes, this may result in different illumination colours, preferably in a blue range.
