1) is formed and the loop portion is hung on the hanging belt support rod (1), the hanging ring (A) is connected to the lower end portion of the hanging belt, and both end portions of the hanging belt are superposed at one place. Both sides of the lever overlapped portion are sandwiched between the seat plates (C) and (C1) and screwed and fixed by the fastening screw (D). (B) In place of the suspension ring (or handle) (A) in (a) above, both ends of the suspension belt hooked on the suspension belt support rod (1) should be inserted above a handle portion (not shown). A stop groove (10) is formed, the lower end portion of the suspension belt is inserted into the stop groove (10), and both are screwed at the insertion portion with a screw (D) that traverses the insertion portion, and the screw is inserted into the insertion portion. The hanging belt (B) is connected to the handle so as to penetrate the lower end of the hanging belt.
In addition, (C) the suspension ring (or handle) in (A) above (A)
In place of the above, the entire outer shape of the handle (not shown) is formed into a substantially triangular shape, and a hanging belt insertion hole is provided in the front-back direction of the upper portion of the handle, and the lower end of the hanging belt hooked on the hanging belt mounting rod is inserted through this hole. Then, both ends of the suspension belt are superposed at one place in the same manner as in (a) above, and the overlapping portion is clamped and fixed by a fastening screw.

On the other hand, the inventor of the present application is the Japanese Utility Model Publication No. 55-1458.
No. 3 hanging ring (or handle) in (a) above (A)
Instead of the suspension belt engaging groove (not shown), a suspending belt having an expanding portion at the lower end is provided with a suspending hole through which the suspending belt is inserted, and the suspending belt is inserted into the suspending hole. A lower end portion having a mounting hole is inserted between the holding pieces of the locking member that can be fitted into the locking hole, and the locking pin is crossed across the holding piece and penetrates through the mounting hole of the lower end portion of the suspension belt. The lower part of the loop part, which is to be attached to the hanging belt support rod (1), is held by being held by the expanded part of the locking hole of the locking part formed at the lower end of the locking member. In the same manner as in (a), there is one in which the hanging belt is sandwiched and fixed by screws and the lower end of the hanging belt is connected to the handle as a single structure as described above.

[Problems to be Solved by the Invention]

As shown in FIG. 4, the above-mentioned connecting structure of the lifting hand is such that the hanging belt (B) is attached to the hanging belt support rod (1) and the loop (B1) is connected to the holding hand (A). The suspension belt (B) has an overlapping portion (P) with the connecting portion, and the sheath (G) portion that binds the overlapping portion is configured to have a double structure (d) and the loop portion (B1). Since the lower part is formed in a triple structure (t), it is not possible to form the hanging belt material having a single structure and sufficient durability against the weight of the handle (A) into a double structure as described above. It is uneconomical because it has excessive quality characteristics, and requires auxiliary means such as a seat plate for fastening both ends of the hanging belt of the hanging, fastening screws and sheaths. However, the machining cost, installation, and removal were troublesome. Furthermore, it was not aesthetically pleasing.

By the way, in order to eliminate the above-mentioned conventional drawbacks, the inventor of the present application has previously mentioned, as mentioned above,
No. 14583 proposed that the suspension belt be connected to the handle as a single structure. However, also in this proposal, similarly to the above-mentioned conventional examples (a) to (c), the upper end mounting portion of the suspension belt with respect to the suspension mounting rod is folded back to form a loop portion and connected in a continuous ring shape. A double structure was formed, and the overlapping portion was screwed from both sides with metal fittings or the like. In addition, as shown in FIG. 4, in the conventional connecting structure of the hanging belt, in order to prevent the hanging hand held by the hanging belt supporting rod from being displaced from a predetermined position during operation, the top peripheral surface of the hanging belt supporting body is prevented. Since an auxiliary means for attaching the lifter movement prevention plate (E) is required, the installation structure of the vehicle lifter becomes very troublesome, and there has been a demand for simplification of installation from the viewpoint of maintenance management.

In order to eliminate the above drawbacks of the conventional vehicle hoist, the present invention makes the hoist belt a simple structure so that it can be easily attached to the hoist belt support rod and the unnecessary constituent materials are cut to suspend. It is an object of the present invention to provide a robust connecting structure for a vehicle hanging hand while reducing the manufacturing cost of the hand structure.

[0007]

In order to achieve the above-mentioned object, the present invention forms a suspension belt attachment groove continuous along the longitudinal direction on the lower peripheral surface of a suspension belt support rod (hollow tube), and A downward recessed groove is formed in a separate locking member that can engage with the opening edge of the mounting groove, and the upper end of the hanging belt is inserted into the recessed groove so as to be clamped and fixed so that it can be inserted and removed from the end face of the mounting groove. While being inserted, both side edge portions of the locking member are fitted to the opening edges of the mounting groove and are suspended in the mounting groove with a single structure, while the lower end portion of the suspension belt is gripped by a normal method. The gist of the configuration is that it is configured to be inserted and fixed in the locking groove provided at the upper end of the.

[0008]

In the connection structure of the hoisting device according to the present invention, one end of the hoisting belt is clamped and fixed in the concave groove of the engaging member that engages with the opening edge of the mounting groove of the hoisting belt support rod (hollow tube). The hanging belt is attached in the state of a single structure, and the other end is inserted and fixed in the locking groove of the handle, so that the hanging belt becomes a mounting part for the hanging belt support rod like a conventional hanging belt. It is not necessary to form a winding part in the loop part and hang it. For this reason, the suspension belt suspended on the suspension belt support rod has a structure in which the overlapping portion (double or triple structure) between the mounting groove and the handle is completely connected at both ends of the suspension belt, so that the suspension belt material is saved and the suspension belt is overlapped. Since it is not necessary to form a screw hole to be provided at a corresponding position corresponding to the part and to clamp and fix this portion with a screw, weakening of the hanging belt material can be prevented and screwing work by these mounting brackets can be omitted. Can be done. Further, the locking member to which the suspension belt is sandwiched and fixed at the opening edge of the mounting groove is engaged, and both side edges of the locking member are fitted to the opening edge of the mounting groove to stabilize the suspension belt support rod. It is attached to the hanger and the hanger is securely held, so there is no risk of it pulling out even if external force is applied.
Further, when both ends of the lifting belt are clamped and fixed to the locking member and the grip, the lifting belt of the clamping portion is folded back to be doubled, or a separate interposing member is additionally provided to clamp the clamping belt. It is possible to make the structure such that the hanging belt is not torn and broken vertically even when subjected to a concentrated load applied to the handle, which makes the life of the hanging hand extremely durable.
