EMBODIMENT OF THE INVENTION Hereinafter, the preferred embodiment of the crane apparatus for wheelchair storage by this invention is described, referring drawings.

Fig. 1 is a view showing a situation where a wheelchair-mounted crane device of the present invention is installed in an automobile. In Fig. 1, a crane device 1 is attached to the trunk of an automobile. The crane device 1 is rotatably mounted to a hinge mechanism part (not shown), in which an arm 4 having a hanger part 3 at the distal end of the support post 2 is covered by a hinge cover 5, and the arm 4 is deployed when the wheelchair 6 is stored. The wheelchair 6 is suspended by the belt 7, and the wheelchair 6 is lifted by a motor (not shown) provided in the hanger 3 to move the arm 4 horizontally and to store the wheelchair 6 inside the vehicle interior. On the other hand, when the wheelchair is not stored in the vehicle interior, the arm 4 is stored as shown by the broken line.

The crane device 1 is equipped with an upper lock lever 에 on an upper portion of the periphery post 2 of the hinge mechanism portion, so that the arm 4 does not move unnecessarily when the arm 4 is unfolded or stored. In addition, the lower lock lever ９ is attached to the lower portion of the support, and the upper lock lever ８ and the lower lock lever 연결 are connected by a connecting means, and can be interlocked.

2 is a view showing a situation in which the upper lock lever ８ and the lower lock lever 장착 are attached, and as an example, shows a state when the arm 4 is deployed. In addition, although the same code | symbol is attached | subjected to the same part as FIG. 1, it is the same in subsequent drawings.

In Fig. 2, the hinge pipe 10 in the hinge mechanism part located at the upper part of the support 2 is formed with cutouts 11 and 12 of two parts, and as shown in the drawing, the lock engaging part 13, which is one end of the upper lock lever 이, is developed in the arm 4. At the time of engagement, it is engaged at the notch 11 and at the time of containment. The hinge pipe 10 is integrated with the movement of the arm 4 and the movement of the containment to rotate about the hinge pipe axis 14.

In addition, the upper lock lever 수 is able to rotate about the upper lock lever shaft 15. When the upper lock lever 회전 is rotated in the direction A of the arrow, the lock engagement portion 13 of the upper lock lever 지는 falls out of the cutout portion 11. The lock is released to allow the arm 4 to be stored. In order for the arm 4 to be stored, the lock engaging part 13 is engaged with the cutout part 12 of the hinge pipe 10 by rotating the upper lock lever 으로 in the direction of the arrow, and the arm 4 is locked in the storing state.

In addition, the upper lock lever ８ is equipped with a return spring 16 on the upper lock lever support shaft 15. Then, pressure is generated while one end of the return spring 16 contacts the inner side of the hinge cover 5, and this pressure prevents the rotational force in the direction A of the arrow of the upper lock lever ，, so that the upper lock lever 항상 is always By rotating on the hinge pipe 10 side (the direction of the arrow), the pressing force is added. As a result, when the upper lock lever 락 is locked, it is kept in a stable lock state. Also, the force to rotate the hinge pipe 10 in the direction of arrow A (clockwise) by the weight of the arm 4 and the weight of the suspended wheelchair 6 Since this rotational force and the force by the return spring 160 are added together, the locked state is further stabilized.

On the other hand, the lower lock lever 9 is provided at the lower portion of the support. The lower lock lever ９ is connected to the upper lock lever ８ by a connecting means 175, and the upper lock lever ８ and the lower lock lever 연동 interlock with each other by the connecting means 175. It becomes possible. The connecting means 175 can use rods, wires, springs, chains, etc., but there is no particular limitation as long as the upper lock lever ８ and the lower lock lever 수 can interlock. The means is preferably metal in strength.

The lower lock lever ９ is rotatable about the lower lock lever support shaft 18. When the lower lock lever 회전 is rotated in the direction A of the arrow, the upper lock lever ８ also connected by the connecting means 17, the arrow A direction. When the lower lock lever is rotated in the Ｂ direction of the arrow, the upper lock lever ８ also rotates in the Ｂ direction of the arrow, while the lock engagement portion 13 of the upper lock lever 부 에 is notched. Will be locked.

In addition, the side engaging with the hinge pipe 10 of the upper lock lever 측, the side connected with the connecting means 175 of the connecting means 173 and the lower lock lever 된다 are arranged inside the prop 2.

Since the lower lock lever 있는 is also provided at the lower part of the support 2 so that the arm 4 can be expanded and stored, the lower lock lever 수 can be operated even when the upper lock lever ８ is in a high position. It is not necessary to perform operations for developing and storing the arm 4, and the operability of the crane device is greatly improved.

By the way, the wheelchair deployment crane apparatus of this invention is equipped with the arm deployment means between the hinge mechanism part and the upper part of a support. FIG. 3 shows the hinge mechanism part of a crane apparatus, specifically, the upper part of the hinge pipe 10 and the support post 2. It is a figure which shows the situation that arm deployment means is attached between and.

Fig. 3A is a diagram showing the situation when arm 4 is being deployed. The arm deployment means can use, for example, elastic force by spring, elastic force by rubber, tensile force by weight, and the like. An example of using spring force as a means is shown, wherein the arm expansion means 18 is in a state where the length of the spring is the shortest, that is, the state where the elastic force is least working. The following figure 3 is the situation when the arm 4 is being stored. In this case, the arm deployment means is a state in which the length of the spring is the longest, that is, the spring is elongated so that the elastic force is the greatest. Therefore, when the arm 4 is stored, the spring of the arm developing means 1 e always extends in the same direction as arrow A for the state in which the elastic force is working the most. As a result, the arm 4 always has the arrow X and the arm 4 even when the arm 4 is stored. The force that tries to develop together works.

In this way, the arm deployment means 18 facilitates the deployment of the arm 4. For example, when the arm is long and the arm is heavy or the person with the weak force develops the arm, On the contrary, there is an advantage that the arm can be deployed even with a small force by using the force by the arm deploying means. Moreover, the arm deployment means 18 is also arranged inside the prop 2.

In addition, as described above, when the arm 4 is stored, the force 4 is always applied to the arm 4 as shown by the arrow Ｂ by the arm expansion means 1. As a result, the force 4 always tries to fall from the prop 2. The state in which the support 2 and the arm 4 contact each other can be avoided, so that the noise (noise) generated by the contact of the support 2 and the arm 4 due to vibration during driving can be suppressed, and the cutout portion 13 is cut out. Since 12 is in close contact, there is no gap between the lock engagement section 13 and the cutout section 12, and there is no fear of noise.

Here, the combination of the upper lock lever, the connecting means, and the lower lock lever and the arm deployment means can be installed alone in the crane device, respectively, but both can be installed at the same time. It is possible to develop and store the arm without using it, and to develop the arm with a smaller force than before, and it is possible to significantly increase the operability of the crane device.

By the way, the lock engagement part of the upper lock lever engaged with the cutout provided in the hinge pipe is provided with the claw (step) for preventing a lock omission (prevention of falling out). A diagram showing a situation engaged in the notch of. In addition, since FIG. 4 is a figure explaining the toenail for preventing a lock omission, only the part which is needed for this description is shown, and the unnecessary part is abbreviate | omitted.

Fig. 4A shows a case where the arm 4 is stored, and the lock engagement portion 13 of the upper lock lever X is engaged with the cutout portion 11 of the hinge pipe 10. As shown in Fig. 4A, the cutout portion of the hinge pipe 10 is shown. The lock engagement portion 13 of the upper lock lever 되고 which is engaged with 11 has claws 20, 21 on both sides. When the arm 4 is stored, the claw 20 enters the inner side of the hinge pipe 10 as shown in the drawing. This makes it difficult for the lock engagement portion 13 of the upper lock lever 빠 to come off and maintains a stable lock state.

On the other hand, when arm 4 is deployed, the lock engagement portion 13 of the upper lock lever 계 is engaged with the cutout portion 12 of the hinge pipe 10, but in this case, the claw 21 enters the inner side of the hinge pipe 10, so that the upper lock The lock engaging portion 13 of the lever 어 is hard to come out and a stable lock state is maintained.

FIG. 5 is a view for explaining a locked state when an unnecessary force is added to the arm 4, and shows a state when the arm 4 is stored. 5, only parts necessary for explanation are shown.

In Fig. 5A, the lock engagement portion 13 of the upper lock lever X is engaged with the cutout portion 11 of the hinge pipe 10. In this case, the lock engagement portion 13 is shown on the left side in the drawing of the cutout portion 11 of the hinge pipe 10. The claws 20 which are in contact with the part and which are broken by the dashed line enter the inside of the hinge pipe 100. Here, the claws 20 are shown by the broken line when the claws 200 are present (dashed line) and the claws are not present (lock shown by the solid line). This is for comparing and explaining the locked state with the engaging portion.

Fig. 5B shows a case where an unnecessary force is added to the arm 4, and the arm 4 is pressed against the support (not shown) side, and a slight gap is formed on the left side in the drawing of the cutout portion 11 of the lock engaging portion 13 and the hinge pipe 10. In this case, if there are no claws 20 (the lock engagement part indicated by the solid line), the lock can be released at any time. On the other hand, if there are claws 20 (shown with the broken line), the claw 20 is inside the hinge pipe 10. As it is still enough, it is still in a stable locked state.

Next, Fig. 5C shows a case where the force is added to the support side with respect to the arm 4 in the state of Fig. 5B. In this case, the gap between the lock engaging portion 13 and the cutout portion 11 of the hinge pipe 10 is completely separated, and the toenail 20 is If there is no lock, the lock is released. On the other hand, if there is a toenail 20, the lock state is still maintained because the toenail 20 still enters the inside of the cutout portion 11 of the hinge pipe 10 and stays there.

As is clear from the above description, in the absence of a toenail, the locked state is easily released. If there is a toenail, it is possible to maintain a locked state even when an inexperienced vibration or shock is added.

Also, when the arm 4 is unfolded, the same as when storing, but not shown, the toenail 21 is engaged with the cutout portion 12, and an involuntary vibration or shock is added to the lock engagement portion 13 and the cutout portion 12 of the hinge pipe 10. Even when a gap is formed between them, a stable lock state is maintained by the toenail 21.

Thus, by forming locks 20 and 21 on both sides of the lock engagement portion 13 of the upper lock lever 하게, stable locking is possible in both the deployment and the storage of the arm 4, and a large vibration is added to the arm 4. Even if an impact such as an object falling on the arm 4 by any cause is applied, the conventional concern that the lock is released is essentially eliminated.

In addition, the claws 20 and 21 are not released by the undesired vibration or shock applied to the crane device 1, but the force applied to the upper lock lever ８ or the lower lock lever 때에 during arm 4 deployment and operation of the containment. It should be a size that can be released without interference.

As described above, the crane device of the present invention has very excellent operability and can maintain a stable locked state at the time of deployment and storage of the arm.

Wheelchair storage crane device of the present invention has a very excellent operability, and can maintain a stable lock state at the time of deployment and storage of the arm, it can be applied to a wide range of vehicles, such as car, business, etc. ．
