Description

  The present application relates to a wear prevention thimble with a hook connected to a lifeline tip provided in a safety belt to be worn on a body for an altitude worker to prevent falling.

  In the past, safety belts have been installed to prevent falling, and work has been carried out at high places. For these safety belts, three-strand ropes, eight-strand ropes, and narrow belts are used as winders. A lifeline of a winding system is connected, and a locking hook provided at the tip of the lifeline is locked to the structure to prevent a fall from a high place.

As shown in FIGS. 7 and 8, the end portion of the conventional belt-like lifeline is designed to prevent wear with the hook H by inserting the bag woven belt 7.
However, since the folded portion is sewn after inserting the belt front end portion into the connecting hole of the hook H for assembly, the hook becomes in the way of sewing and the workability is poor.
Further, the heat-shrinkable tube 5 is put on the sewn portion to protect the thread of the sewn portion. Even during this heat-shrinking operation, the hook H is obstructive and the workability is poor.
Further, the step difference between the belt-shaped lifeline B and the bag-woven belt 7 is large, and even if it is protected by the heat-shrinkable tube 5, it becomes an uneven shape, and the appearance is poor. Further, the heat-shrinkable tube 5 may be damaged when the convex and concave portions hit a structure or the like.

As a conventional one, there is a design registration No. 1111055.
This is a protective thimble of a synthetic resin belt that is inserted into the end of the safety band, and after the protective thimble is inserted into the connecting hole of the hook for assembly, the folded portion is sewn. Similarly, hooks are attached at the time of processing, and workability is poor.
Design registration No. 1111055

  The present application was invented for the purpose of easily performing the end processing of the belt-shaped lifeline of the safety belt for preventing crash.

In the present application, the resin thimble is divided into two parts, a female member 1 and a male member 2, and after the end of the lifeline is sewn, the resin thimble is fitted to the end ring-shaped portion.
Specifically, a substantially cam-shaped inner cylinder provided with a through hole and a keyhole-shaped hole provided with a recess coupled to the hole, and an outer wall provided with an open portion outside the inner cylinder, A female member provided with a belt insertion portion between the inner cylinder and the outer wall;
From an inner cylinder that fits into a through-hole provided with a convex portion corresponding to the concave portion, an outer wall that provides an open portion on the outside of the inner cylinder, and a male member that provides a belt insertion portion between the inner cylinder and the outer wall Of the structure

As mentioned above, by post-assembling the divided resin thimbles at the end of the belt-shaped lifeline, the workability of the belt end sewn and heat-shrinkable tube is greatly improved, and there is no stock of hooks Even a lifeline can be processed.
In addition, even if it is assembled, it is possible to replace the hook by removing the rivet, and it is possible to quickly respond to the number of orders for different model numbers of the hook, and it is easy to manage inventory.

Detailed examples of the present application:
As shown in the figure, a round hole 12 penetrating inside, a substantially cam-shaped inner cylinder 11 provided with a keyhole-like hole provided with a recess 13 coupled to the round hole 12, and on the outside of the inner cylinder 11 A female member 1 provided with an outer wall 15 provided with an open portion 14, and provided with a belt insertion portion 16 between the inner cylinder 11 and the outer wall 15,
An inner cylinder 21 that fits into a through-hole 12 provided with a projection 23 corresponding to the recess 13, and an outer wall 25 that is provided with an open portion 24 outside the inner cylinder 21 are provided between the inner cylinder 21 and the outer wall 25. And a male member 2 provided with a belt insertion portion 26.

  The female member 1 has a substantially cam-shaped inner cylinder 11 provided with a round hole 12 that penetrates and a recess 13 that protrudes into the round hole 12 to provide a keyhole-like hole, and the outer side of the inner cylinder 11 Further, an outer wall 15 provided with an open portion 14 is provided, and a belt insertion portion 16 is provided between the inner cylinder 11 and the outer wall 15.

  The male member 2 is provided with an inner tube 21 that fits into the round hole 12 of the female member 1 and a convex portion 23 that fits into the recess 13 partway, and an outer wall that has an open portion 24 outside the inner tube 21. 25, and a belt insertion portion 26 is provided between the inner cylinder 21 and the outer wall 25.

The thimble for the terminal part of the belt-like lifeline of the present application is configured such that the terminal part of the belt-like lifeline B is folded to sew the overlapping portion, and the sewing thread is protected by the heat shrinkable tube 5.
As shown in FIGS. 4 and 5, after processing of the belt-like lifeline B, the female member 1 and the male member 2 can be fitted to the folded ring-shaped portion, and the hook H can be attached by the U ring 3 and the rivet 4. is there.

  FIG. 6 shows another embodiment of the thimble for the terminal part of the belt-like lifeline of the present application, in which the convex part is not provided on the side wall part, the U ring 3 is rotated, The effect is equivalent.
