That is, the carrier bridge 36 can be pulled to the side of the vehicle (the side on which the user is standing) to perform the lifting work and the detaching work of the bicycle 6 without interfering with the body of the automobile.

Next, the operation mode of the present embodiment having the above configuration will be described in more detail. (Unloading position → loading operation → loading position) As shown in FIG. 3, at the unloading position, the accumulator 14
24 is above the dead center D of the power transmission means 12. Therefore, the driving force of the accumulator 14 is absorbed by the stopper 18 via the first rocker 20, and the arm member 4 is stably held at this unloading position. The user holds the bicycle holder 8 in this state.
Securely attach the bicycle 6 to the (indicated by the solid line in FIG. 2). Then, in order to lift the bicycle 6 to the loading platform 2, the bicycle 6 is moved upward (the loading rotation direction 8 shown in FIG. 2).
Then, the accumulator 14 is rotated to position the force point 24 below the dead point D. This emphasis point 2
By the movement of 4, the rod 14a of the accumulator 14 held by the stopper 18 releases its driving force and projects from the accumulator 14, and then gives a pivotal force to the pivot arm 4a via the connecting member 44. . Therefore, the pivot arm 4a is sufficiently pivoted to the position shown by the imaginary line in FIG. 2, and the locking piece 28 is elastically abutted against the cushion member 52 at the loading position as shown in FIG. By engaging with the lock pin 26, the shared support 16 is securely held. Then, as shown in FIG. 1, the front and rear wheels of the bicycle 6 are attached to the carrier bridge 36.
The vehicle can be driven with the bicycle 6 placed on the luggage carrier 2 after being fastened with the band member 60.

(Loading position → unloading operation → unloading position) When the bicycle 6 is unloaded from the loading platform 2, the common support 1 is used.
After pulling the operation portion 6a (see FIG. 5) projecting from the side surface of 6 to release the holding means 10, the arm member 4 is moved to
It is rotated in the unloading rotation direction 82 shown in FIG. At this time,
As shown in FIG. 4, the weight of the bicycle 6 that is unloaded is such that the connecting member 44, the rotating shaft 22 (power point 24), and the rod 14a.
The amount of change in the potential energy of the bicycle 6 is transmitted to the accumulator 14 via the. That is, the weight of the bicycle 6 received by the user during the unloading process is reduced by the driving force of the accumulator 14 applied to the pivot arm 4a in the loading direction.
When the bicycle 6 approaches the unloading position, the accumulator 14 rotates and the force point 24 is located above the dead point D. As a result, the driving force of the accumulator 14 is absorbed by the stopper 18, and the original state (unloading position) shown in FIG. 3 is obtained. In this unloading position, the user can remove the bicycle 6 from the bicycle holder 8 while the arm member 4 is stably held.

(Operation of the device when the bicycle is not loaded) When the bicycle 6 is not loaded, when the arm member 4 is rotated with the driving force of the accumulator 14, the arm member 4 is moved in the loading process. While the turning force is applied more than necessary, inconvenience may arise in that the unloading process must be manually rotated against the driving force of the accumulator 14. However, in the present embodiment, the above problem can be solved by releasing the fixing means 50 between the pivot arm 4a and the second rocker 46 as shown in FIG. That is, when the arm member 4 is stored in the luggage carrier 2 after the bicycle 6 is removed at the unloading position, the arm member 4 is rotated in the load-up rotation direction 80 while holding the fixing lever 50a by hand. The engagement between the fixed lever 50a and the pivot arm 4a can be released.
As a result, the pivot arm 4a and the power transmission means 12 are separated from each other, and at the same time, the power transmission means 12 and the accumulator 14 are held in the state shown in FIG. 12, so that the arm member 4 can be freely moved regardless of the driving force of the accumulator 14.
Can be rotated.

(Effect of this embodiment) According to the bicycle lifting device of this embodiment, the bicycle 6 mounted on the arm member 4 via the bicycle holder 8 is placed at the loading position (the loading platform 2) and the unloading position. The arm member 4 can be moved up and down while drawing a predetermined locus as the arm member 4 rotates. Therefore, the bicycle 6 can be lifted and lowered more accurately as compared with the case where the bicycle 6 is manually held and lifted without the arm member.

Further, since the arm member 4 can be held on the loading platform 2 by the holding means 10 at the loading position where the bicycle 6 is placed on the loading platform 2, the held arm member 4 itself becomes an attachment. Therefore, it is not necessary to assemble the attachment and the bicycle on the luggage carrier 2 as in the conventional case, and the workability is improved.

Since the force required to lift the bicycle 6 can be applied to the bicycle 6 from the accumulator 14, the user can easily lift the bicycle 6 onto the luggage carrier 2. On the other hand, in the unloading process, the weight of the bicycle 6 received by the user is reduced, so it is not necessary to unload the bicycle 6 while supporting the entire weight of the bicycle 6,
The bicycle 6 can be easily unloaded from the loading platform 2.

On the upper side of the dead point D, the driving force of the accumulator 14 is applied to the power transmission device 12 and the arm member 4.
Since it brings about the effect of stabilizing the bicycle 6 in the stationary position, the user can attach and detach the bicycle 6 in a state where the bicycle 6 is stably stationary in the unloading position.

Further, since the bicycle 6 is in a standing state at each of the loading position and the unloading position, the user can place the bicycle 6 on the loading platform 2 in a normal posture (running / stopped state). In addition to being able to do so, it is possible to ride the bicycle 6 when it is unloaded.

Further, the locking piece 28 can be removed from the lock pin 26 only by pulling the operation portion 26a protruding from the side surface of the common support 16 toward you. At the same time, the operation unit 2
Since 6a and the lock pin 26 are composed of the same component, the holding means 10 can be simplified, the number of components can be reduced, and the device can be constructed at low cost.

8 On the other hand, the power transmission means 82 shown in FIG. 13 is one in which the second rocker 46 and the rod 14a are directly connected, and because of the configuration of the power transmission means 12, the first rocker 20 and the connecting member 44 are provided. The number of parts is reduced by omitting. The power transmission means 82 has three joints, and operates on the shared support 16 with the rotating shaft 38 as a fulcrum and the rotating shaft 84 as a force point 86. In FIG. 13, the loaded state is shown by a solid line, and the broken line shows the form of each component at the unloading position. Then, according to the power transmission means 82, at the unloading position, the power transmission means 82 is located above the dead point D connecting the rotating shaft 38 (fulcrum) and the force point 86. Further, when the pivot arm 4a is slightly rotated in the load-up rotation direction 80 from the unloading position, the force point 86 becomes the dead point D.
