Description
Background of the Invention
There are numerous types or styles of bicycle carrier racks for automobiles. However, most of such racks have several disadvantages. Many such known bicycle carrier racks require considerable space for storage and are not readily portable when not in use. Other known bicycle carrier racks are difficult and/or time-consuming to assemble or to mount or to attach to an automobile. Most known bicycle carrier racks may be easily stolen from an automobile. Therefore, both the carrier rack and each bicycle supported thereby may be easily stolen.
Other known bicycle carrier racks are so mounted that the trunk lid or cover cannot be moved to open position when the bicycle carrier rack is fully and completely attached to an automobile for support thereby.
Other known bicycle carrier racks are not capable of firm and strong support of a bicycle or a plurality of bicycles.
It is an object of this invention to provide a bicycle carrier rack which can be readily collapsed into a folded condition to occupy minimum space when not in use. Thus, the bicycle carrier rack can be readily stored or transported when not in use.
Another object of this invention is to provide such a bicycle carrier rack which can be readily and easily and quickly attached to an automobile for support thereby.
Another object of this invention is to provide such a bicycle carrier rack which is locked to the automobile when the bicycle carrier rack is mounted upon and supported by the automobile.
Another object of this invention is to provide such a bicycle carrier rack which does not interfere with opening of the trunk cover or lid when the bicycle carrier rack is completely attached to the automobile.
Another object of this invention is to provide such a bicycle carrier rack which is capable of firm and strong support of one or more bicycles.
Another object of this invention is to provide a rack which is attachable to an automobile for support of objects, devices, and materials other than bicycles.
Other objects and advantages of the bicycle carrier rack of this invention reside in the construction of parts, the combination thereof, the method of production, and the mode of operation, as will become more apparent from the following description.
Brief Summary of the Invention
A bicycle carrier rack for automobiles of this invention comprises a pair of elongate main support members. A pair of connector members are pivotally attached to each of the main support members. The connector members are pivotally attached one to the other. The bicycle carrier rack also includes means for securing the angular relationship between the connector members. A cross-member has a pivotal portion pivotally connected to one of the main support members and a clamping portion engageable with the other main support member. An extension member is joined to the second connector member and is engageable with a trunk portion of the body of an automobile. The trunk cover is closeable upon a part of the extension member and secures the bicycle carrier rack to the automobile. The bicycle carrier rack also includes a pair of laterally extending support members, each of which is rigidly attached to one of the main support members. The laterally extending support members are adapted to support one or more bicycles.

Detailed Description of the Invention
A bicycle carrier rack 14 of this invention comprises a pair of elongate support members 16 and 20. A stem 22 is attached to the support member 16 intermediate the ends thereof. The stem 22 is substantially normal to the support member 16 and has an engagement member 24 at the end thereof. Attached to the support member 16 adjacent the lower end thereof is a stem 26 which is normal to the support member 16 and has an engagement member 28 at the end thereof.
Attached to the support member 20 intermediate the ends thereof is a stem 30, normal to the support member 20, and having an engagement member 32 at the end thereof. Attached to the support member 20 adjacent the lower end thereof is a stem 34 which is normal to the support member 20 and has an engagement member 36 at the end thereof.
Pivotally attached to the stem 22 is an elongate connector member 40. Pivotally attached to the stem 30 is an elongate connector member 42. A pin 44 intermediate the ends of the connector members 40 and 42 pivotally attaches together the connector members 40 and 42. Adjacent the end of the connector member 40 is a socket 48. Pivotally attached to the connector member 42 by means of a pin 50 is a bracket 52 which has a lug 54 attached thereto. A spring 56 is attached to the connector member 42 and to the bracket 54 and urges pivotal movement of the bracket 54 toward the pin 44. A handle 58 is attached to the connector member 42, for pivotal movement thereof.
Pivotally joined to the support member 16 by means of a pin 60 is a cross-member 62. Rotatively attached to the cross-member 62 at the end thereof and in axial alignment therewith is a shaft 66. Secured to the shaft 66 adjacent the end thereof is a cam 68. Secured to the shaft 66 and extending laterally therefrom is an extension member 67 having an arcuate end portion 69. Attached to the support member 20 intermediate the ends thereof is a bracket 70. Adjacent the bracket 70 is a protuberance 72. Adjacent and below the protuberance 72 is a fixed cam surface 74.
Adjacent the upper end of the support member 16 is a laterally extending support arm 80. Adjacent the upper end of the support member 20 is a laterally extending support arm 82.
Operation
FIG. 2 shows a bicycle carrier rack 14 of this invention in a folded or collapsed condition. Thus, the bicycle carrier rack 14 can be stored or transported in a relatively small space.
FIGS. 1, 3, 6, 7, and 8 illustrate a portion of an automobile 90 which has a trunk cover or lid 92, a substantially vertical lower trunk panel or wall 94, and a rear bumper 96. When it is desired to mount the bicycle carrier rack 14 of this invention upon an automobile, such as the automobile 90, the elongate support members 16 and 20 are moved in directions one from the other as the connector members 40 and 42 are pivotally moved with respect thereto to position the connector members 40 and 42 in substantially aligned relationship. In this position of the connector members 40 and 42, the lug 54 of the bracket 52, which is attached to the connector member 42, is positioned within the socket 48 of the connector member 40. Then the support members 16 and 20 are angularly moved as the upper portions thereof are initially moved one from the other, and with such relative angular movement of the support members 16 and 20, the lower portions of the support members 16 and 20 are brought into engagement with the bumper 96, as the upper portions of the support members 16 and 20 are moved in directions one toward the other. The support members 16 and 20 are angularly moved to position the engagement members 24, 28, 32, and 36 in engagement with the inner surface of the bumper 96, as the support members 16 and 20 are in engagement with the outer surface of the bumper 96, as illustrated in FIG. 3.
Then the cross-member 62, which is attached to the support member 16, is pivotally moved toward the support member 20, as illustrated in FIG. 6. The cross-member 62 is pivotally moved until the end of the shaft 66 rests within the bracket 70 which is attached to the support member 20, as illustrated in FIG. 7. In this position the extension member 67 extends in a direction from the automobile 90, as illustrated in FIG. 7.
Then the extension member 67 is moved toward the automobile 90, as the shaft 66 is rotatively moved. When this occurs, the lid or cover 92 of the trunk of the automobile is in a raised position. The arcuate portion 69 of the extension member 67 is moved into a position over the upper edge of the lower trunk panel 94, as illustrated in FIG. 8. Then the trunk lid or cover 92 is moved to closed position and is in engagement with the upper edge of the lower panel of the trunk. When the lid or cover is closed and locked, the extension member 67 is secured to the trunk portion of the automobile 90, between the lower trunk panel 94 and the cover 92.
When the extension member 67 is pivotally moved from the position thereof shown in FIG. 7 to the position shown in FIG. 8, the shaft 66 is rotatively moved. Thus, the cam 68 is rotatively moved. Thus, the cam 68 rotates in engagement with the cam surface 74 and moves from the position thereof shown in FIG. 9 to the position thereof shown in FIG. 10. Such movement places tensional forces upon the shaft 66 and the cross-member 62, urging the upper portions of the support members 16 and 20 one toward the other. Such urging of the upper portions of the support members one toward the other, increases the clamping forces of the support members 16 and 20 upon the bumper 96. Thus, the support members 16 and 20 are clamped and secured to the bumper 96.
In the rotative position of the cam 68 as shown in FIG. 10, the cam 68 is below the protuberance 72 and cannot be lifted therefrom without rotative movement of the shaft 66. Thus, when the arcuate portion 69 of the extension member 67 is locked under the trunk cover 92, the cross-member 62 is locked in the position shown in FIG. 8. Furthermore, the entire bicycle carrier rack 14 is thus locked or secured to the automobile 90 and cannot be removed therefrom until the cover 92 is lifted and the extension member 67 rotatively moved in a direction from the automobile 90.
FIG. 1 illustrates use of the bicycle carrier rack 14 of this invention in which a bicycle is supported by the support arms 80 and 82.
The support arms 80 and 82 are adapted to support devices, articles and materials other than a bicycle or bicycles.
Although the preferred embodiment of the bicycle carrier rack of this invention has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof, and the mode of operation, which generally stated consist in a structure within the scope of the appended claims.
