Abstract

(57) [Abstract] [Purpose] To provide a safety belt that has a function of absorbing and mitigating the impact of a drop impact on a ring and that is safe and can reliably prevent a fall. [Structure] Two or three sides 2 parallel to one side of the connecting side 1 are added, and both ends thereof are connected to each other to form a substantially date-shaped or eye-shaped belt mounting portion 3 and the connecting side 1. On the other side, a rope attachment part 5 with a semi-circular side 4 is provided, and the belt attachment part 3 and the rope attachment part
A configuration in which 5 and 5 are bent at a predetermined angle in the vicinity of the connecting side 6. [Effect] When dropped, the normal position of the ring is pulled so that the shock load is absorbed and relieved, and a safe and reliable fall prevention is possible.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present application relates to a safety belt worn by an aerial worker on the waist to prevent a fall, and particularly to a ring for connecting a rope with a hook at its tip to a belt of the safety belt.

[0002]

[Prior art]

 The ring used in the past has a D shape as shown in FIGS. 8 and 9. When connecting with the belt of the safety belt, after inserting the ring collar C on the connecting side, the D ring made of resin is used. The belt B was inserted through the stopper A. However, as shown in FIG. 9, the belt on the right side of the ring is inserted through the D ring stopper A alternately and is relatively firmly attached, but the belt on the left side of the ring is the D ring. Even if it passes through the stop slit once, the belt holds the ring by the tensile force applied to the belt when wearing it on the waist, but when there is no load, the belt rises to the ring side, Sometimes the ring loosened and moved. In addition to such a horizontal movement on the belt, if an operator should drop from a high place, the belt may be biased to one end (upper end or lower end) of the connecting side by a shock load and be biased. On the other hand, the rope attached to the semi-circular side is located at the other end of the connecting side, and a tensile load in the direction of the arrow is generated. Could not be done. (Shown in Figure 10)

[0003]

[Problems to be solved by the device]

 Therefore, the present application provides a safety belt ring that not only prevents a fall, but also absorbs and absorbs impact loads as described above, is safe, and can reliably prevent a fall.

[0004]

[Means for Solving the Problems] In order to absorb and relax the impact load in the ring, a special steel material is not used, but the shape of the ring is used. Is provided to prevent movement when inserting the belt, to prevent deviation of the belt to one side of the connecting side when falling, and to apply force to the normal position (center of the semi-circular portion of the rope attachment part). The extension of the mounting side absorbs and alleviates shock.

【Example】

 The present application will be described in detail.The present application is formed by punching or forging by press working, and includes a belt mounting portion 3 and a semi-arcuate rope mounting portion 5 bent at a predetermined angle from the belt mounting portion 3. Consists of The belt attachment part 3 is a part in which a flat side 2 having substantially the same length is added in the plane formed by the connecting side 1 connecting the both ends of the semi-circular side 4 and the both ends are connected. If two sides 2 are added, it becomes a substantially Japanese letter shape, and if three sides 2 are added, it becomes a substantially eye-shaped shape. The rope attachment part 5 connects the semi-circular arc side 4 at a predetermined angle to both ends of the connection side 1, and this angle D is about 60 ° to 70 ° and is expected to be deformed by an impact load. Is. FIGS. 1 and 2 show the first embodiment. Of the above ring, two sides 2 are provided so that the belt mounting portion 3 has a substantially date-like shape, and the connecting side 1 and the vicinity 6 are bent to one side. It is a thing. FIG. 3 is a front view of the second embodiment. The difference from the first embodiment is that the side 2 is provided with three sides 2 and the belt attachment portion 3 is formed in a substantially eye shape, and the belt insertion coupling is first It can be performed more strongly than the embodiment. FIG. 4 is a bottom view of the third embodiment. The difference from the first embodiment is that the rope attachment part 5 is bent in the vicinity of the center 7 and bent in a substantially Z shape. It prevents the rope attachment part 5 of the arcuate side 4 from protruding from the body part, and absorbs and relaxes the impact load by the extension of the two bent parts. A ring collar is not provided on the belt mounting portion 3 of the ring so that the side 2 can be easily bent and stretched to absorb and reduce impact load.

The ring of the present application is assembled in a safety belt as shown in FIG. 5, mounted on the waist of an operator, and hooks are hung on a structure or the like. In the event of a drop, the ring of FIG. Since the belt mounting portion 3 inserted into the belt B does not move like this, the belt B and the rope R pull the center portion of the ring in both directions without any deviation, and the side 2 and the semicircular side 4 are deformed. The extension (deformation) of the bent part near the connecting side 6 absorbs the drop impact load. Even if the ring of the third embodiment shown in FIG. 4 is used, the drop impact load is absorbed by the extension of the two bent portions in the same manner.

[0007]

[Effect of device]

 By adopting the ring of the present application as described above, it is possible to absorb and relieve the impact force of a fall, and it is possible to safely and reliably prevent a crash. Since it can be mitigated, it can prevent secondary disasters such as internal organ damage when it falls. In addition, since the ring is manufactured in the same manner as the conventional product, the cost does not increase, and in the conventional product, the ring may rotate in the ring collar and the upper ear portion of the belt may be worn. However, since the ring of the present application does not rotate, the ears are not worn and the belt is not deteriorated in strength.
