SUMMARY OF THE INVENTION
An object of the present invention includes a bicycle carrier for a vehicle in which the bicycle carrier includes tail lights operable to function in a neutral position and an operating position of the bicycle carrier.
In carrying out the above object and other objects, the present invention provides a bicycle carrier having a base holder mountable to a vehicle and a support holder for holding a bicycle. The support holder is movably connected to the base holder to be movable along a longitudinal direction of the vehicle between a neutral position in which the holders extend over one another and an operating position in which the support holder extends out from the base holder. A tail light(s) is movably connected to the support holder to be movable between a stored position in which the tail light is stowed in the support holder when the support holder is in the neutral position and a functional position in which the tail light extends out from the support holder and is orientated transversely to the longitudinal vehicle direction when the support holder is in the operating position.
Advantages achieved by a bicycle carrier in accordance with embodiments of the present invention are that the tail lights in the operating position of the carrier may be fixed in a functional position, and the function as tail lights may then be realized in a specific manner. In contrast, in the neutral position of the carrier the tail lights may be placed in a space-saving stored position. Quick-release devices which may be implemented by reasonable technical means are provided to move the tail lights between the stored and functional positions. A simple plug-in connection having a receiving element and an insertion element which may be easily operated is suitable for a quick-release device. This also applies to the fixing element for the quick-release device, which by a spring-loaded locking member positions the insertion element relative to the receiving element. The locking member is influenceable by an actuating mechanism. The spring element includes a compression spring. The actuating mechanism has a convertible actuating pin having a guide section enclosed by the compression spring. The actuating pin includes a first stop for a first end side of the compression spring. The compression spring is supported at a second end side on an inner side of a stop wall of a housing section. A bearing bolt designed as an extension of the actuating pin passes through the stop wall and also passes through a hand lever which can axially move the actuating pin. The hand lever has an ergonomic design which facilitates operation of the fixing element. An electrical switching device between the holders allows the tail lights to be switched off in the stored position in order to eliminate interfering light effects from the tail lights when in the stored position, and switched on in the functional position.
The above features, and other features and advantages of the present invention are readily apparent from the following detailed descriptions thereof when taken in connection with the accompanying drawings.

In order to enable support holder 7 to be movable relative to base holder 6, base holder 6 includes inner guide rails 8, 9 and support holder 7 includes corresponding outer guide rails 10, 11. Inner guide rails 8, 9 are transversely spaced apart from one another on respective sides of base holder 6 and run along longitudinal vehicle direction C-C. As such, inner guide rails 8, 9 are on respective sides of central longitudinal plane B-B. Likewise, outer guide rails 10, 11 are transversely spaced apart from one another on respective sides of support holder 7 and run along longitudinal vehicle direction C-C. As such, outer guide rails 10, 11 are on respective sides of central longitudinal plane B-B. Inner guide rails 8, 9 cooperate with outer guide rails 10, 11 to enable support holder 7 to move relative to base holder 6 along longitudinal vehicle direction C-C between neutral position Rs and operating position Bs.
A panel wall 14 is connected to support holder 7. Panel wall 14 closes off opening 3 on both sides of central longitudinal plane B-B when support holder 7 is in neutral position Rs. Tail lights 12, 13 are positioned on respective ends of panel wall 14. Each tail light 12, 13 has an approximately rectangular body. Tail lights 12, 13 are respectively connected to a vehicle electrical system by electrical cables 15, 16. Tail lights 12, 13 are movable between a functional position Wist when support holder 7 is in operating position Bs and a stored position Abst when support holder 7 is in neutral position Rs. FIG. 2 illustrates tail lights 12, 13 in functional position Wist. FIG. 3 illustrates tail lights 12, 13 in stored position Abst.
Tail lights 12, 13 stow in a storage compartment 17 of support holder 7. Tail lights 12, 13 are flatly folded and largely countersunk within storage compartment 17 when tail lights 12, 13 are stowed in storage compartment 17. From stored position Abst, an operator of vehicle 1 may manually move tail lights 12, 13 to functional position Wist.
Quick-release devices 18, 19 respectively associated with tail lights 12, 13 fix tail lights 12, 13 in place when tail lights 12, 13 are in functional position Wist. Tail lights 12, 13 are structurally and functionally similar and quick-release devices 18, 19 are structurally and functionally similar. As such, the description below regarding tail light 12 and quick-release device 18 corresponds to tail light 13 and quick-release device 19.
Referring now to FIGS. 4 and 5, with continual reference to FIGS. 1, 2, and 3, views of tail light 12 in functional position Wist and in the direction of arrow A of FIG. 4, are respectively shown.
