Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a hanging rope terminal device used for connecting a hanging rope of an elevating type lighting device to a winch side rope material, etc.

[Background technology]

Conventionally, in lighting fixtures installed on high ceilings of stages, gymnasiums, etc., for ease of maintenance, the lighting fixtures 51 are connected to hanging cables 52 as shown in FIG.
There is one that is suspended so that it can be raised and lowered. 53 and 54 are pulleys, and 56 is a hand-wound winch. Hanging rope 5
As shown in FIG. 11, the ends of the cables 2 and 2 are tied together with a binding device 58 to form a loop portion 52a, which is engaged with the hook 59 of the rope material 57 on the winch 56 side.

Since the length of the hanging rope 52 on the side of the lamp 51 varies depending on the ceiling height of the installation site and the horizontal distance from the position of the winch 56, the end portion cannot be pretreated at the factory. Therefore, as a binding tool 58 for forming the loop portion 52a, a screw type binding tool 58 ₁ shown in FIGS. 13 and 14 is used.
Alternatively, a caulking type binding tool ₅₈₂ shown in FIG. 15 is used.

Screw-type binding device 58 ₁ in FIGS. 13 and 14
This is provided with a binding main body 61 through which the hanging rope 52 is passed, and nuts 62 through which the hanging rope 52 is passed on both sides of the loop portion 52a, and the hanging rope 52 is prevented from coming off by tightening the nuts 62.

However, the holding force varies greatly depending on the insertion length of the terminal end 52a of the hanging rope 52 and the tightening force of the nut 62, and the hanging rope 52 may come off.

The caulking-type binding tool ₅₈₂ in FIG. 15 is sleeve-shaped, and the hanging rope 52 is passed through and fixed by caulking. 59' is a hanger.

However, a special tool is required for the caulking work of the caulking type binding tool ₅₈₂ , and it is very inconvenient to prepare such a special tool at the construction site.

[Purpose of invention]

This invention provides a sling terminal that can easily form the loop part of the sling without using special tools, can firmly hold the loop part without coming off, and has excellent operability. The purpose is to

[Disclosure of invention]

The hanging rope terminal device of this invention is provided with a terminal device main body having two rows of cable insertion holes penetrating the front and back sides, each row having a plurality of cable insertion holes in each row, and the terminal portion of the hanging rope is inserted from one end of the terminal device main body into one row. Pass the cable through each cable insertion hole alternately from front to back.
After the insertion, form a loop portion and pass it alternately from the other end of the terminal device main body through each cable insertion hole in the other row in the same manner as above, so that the most end portion of the hanging rope is connected to the terminal device body of the hanging rope. They are bound together with a binding tool along parallel to the non-insertion part and concealing the terminal end part.

According to the configuration of this invention, since the hanging ropes are passed through the plurality of cable insertion holes in the terminal body on both sides of the loop portion alternately on the front and back sides, the hanging ropes and the inner surface of the cable insertion holes are large when a load is applied. Frictional force acts. In addition, since the end of the sling cable is tied parallel to the non-inserted part of the sling cable, the sling cable is held down along the surface of the terminal body, making it even larger at the outlet of the cable insertion hole. Frictional force is obtained. Therefore, strong holding without the loop portion coming off can be achieved. In this way, since the terminal device main body can provide the force to prevent the device from coming off, the binding tool may be a simple one that does not require any force to prevent the device from coming off.

In addition, to form the loop part, all you have to do is insert the hanging cable through the cable insertion hole in the terminal body and fasten the end part with a simple binding device that does not require any pulling force, so no special tools are required. , can be easily formed in the field. Furthermore, since the most terminal part of the hanging rope is hidden within the binding tool, the hanging rope terminal part does not get jammed during operation.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 6. This hanging rope terminal device is provided with a terminal device main body 3 having two rows of cable insertion holes 1 and 2 that penetrate through the front and back sides, and a terminal portion of the hanging rope 4 is inserted from one end of the terminal device main body 3 to one side. Pass through each cable insertion hole 1 in the row alternately from front to back in turn, form a loop portion 4a after insertion, and pass alternately from the other end of the terminal main body 3 through each cable insertion hole 2 in the other row in the same manner as above, The terminal end portion 4b of the suspension rope 4 is tied in parallel with the non-insertion portion 4c of the suspension rope 4 into the terminal main body 3, and the terminal end portion 4b is concealed and tied with a binding device 5.

The hanging rope 4 is made of wire rope or the like. The terminal main body 3 has a flat plate shape as shown in FIG.
The thickness t is, for example, 4 to 6 mm. The cable insertion holes 1 and 2 have chamfered portions 6 on both ends, and the inner diameter d is
3.5 to 6 mm, and the chamfered portion 6 is set to c0.3 to 0.8.

As shown in FIGS. 4 and 5, the binding device 5 consists of a threaded cylindrical binding device main body 5A and a nut 5B, and two small holes 7 are provided in the end wall of the nut 5B. The hanging rope 4 is passed through the small hole 7 of the nut 5B and inserted into the inside of the binding main body 5A. By tightening the nut 5B in this state, the suspension rope 4 is tightened by the nut 5B.
It is held between the inner surface of the end wall and the tip of the binding tool main body 5A.

FIG. 2 shows a lighting device using this hanging rope terminal. The light fixture 8 is attached to the hanging rope 4 hung from the pulleys 10 and 11 on the ceiling 9, and the hanging rope terminal A of the hanging rope 4 is attached to the wall surface 1.
It is connected to the suspension rope 15 of the winch 14 of No. 3 via a hook 16. The winch 14 is of a hand-wound type and has a handle 17.

As shown in FIG. 6, the hanger 16 consists of two bending plates 16A and 16B that are passed through the rope portion 15a of the winch-side cable material 15.
The tips of A and 16B are connected with bolts 18 after passing through the rope portion 4a on the hanging rope 4 side. 19 is a bolt insertion hole, and 20 is a screw hole.

According to this configuration, since the suspension rope 4 is passed through the plurality of cable insertion holes 1 and 2 of the terminal main body 3 alternately on the front and back sides on both sides of the loop portion 4a, when a load is applied, the suspension rope 4 and the cable insertion hole 1 are passed through each other alternately. A large frictional force acts on the inner surfaces of , 2 and 2. Moreover, since the terminal end 4b of the hanging rope 4 is tied parallel to the non-insertion part 4c of the hanging rope 4, the hanging rope 4 can be tied as shown by arrow Q in FIG. 5A.
It is pressed inward along the surface of the terminal device main body 3, and an even greater frictional force is obtained at the exit portions P of the cable insertion holes 1 and 2. Therefore, the suspension rope 4 does not slip, and the loop portion 4a can be firmly held without coming off.

The binding device 5 is used to protect the terminal end portion 4b of the hanging rope 4 and to bring it together to the non-insertion portion 4c of the hanging rope 4. Even if tension is applied to the hanging rope 4, all the force is applied to the terminal device main body 3 and the hanging rope 4, and does not act on the binding tool 5.

Therefore, the binding tool 5 only needs to be provided so that it does not shift from the suspension rope 4 without any load, and strong fixing is not required, making installation very simple. Further, the connection between the hanging rope 4 and the terminal main body 3 can be easily performed by simply passing the hanging rope 4 through the cable insertion holes 1 and 2. Therefore, the rope portion 4a of the hanging rope 4 can be easily made on site without requiring any special tools.
Further, since the end portion 4b of the hanging rope 4 is hidden within the binding tool 5, the hanging rope 4 does not get caught on a guide or the like when the lamp 8 is raised or lowered, and smooth operation is possible. Moreover, since the end portion 4b is tied with the binding tool 5, the binding of the hanging rope 4 becomes even stronger.

7 to 9 show other embodiments. In this example, a binding device 5' is used in which the terminal end portion 4b and non-insertion portion 4c of the suspension rope 4 are directly held down by a set screw 29. The binding main body 20 has a two-width suspension cable insertion hole 21 and a set screw threading hole 22. Although the terminal main body 3' has a planar shape different from the example shown in FIG. 4, cable insertion holes 1 and 2 are similarly provided therein. Even with this configuration, the same effects as in the embodiment described above can be obtained.

In the above embodiment, the terminal main bodies 3, 3' are plate-shaped, but they may also be block-shaped. Moreover, three or more cable insertion holes 1 and 2 may be provided in each row. Further, the binding tool 5 may be a cylindrical member or a band member that can be crimped manually or with a simple tool.

[Effect of idea]

In the cable terminal of this invention, the cable is passed alternately from front to back through the multiple cable insertion holes in the terminal body on both sides of the loop part, so that when a load is applied, the cable and the inner surface of the cable insertion hole are connected to each other. A large frictional force acts. In addition, since the end of the sling cable is tied parallel to the non-inserted part of the sling cable, the sling cable is held down along the surface of the terminal body, making it even larger at the outlet of the cable insertion hole. Frictional force is obtained. Therefore, strong holding without the loop portion coming off can be achieved. In this way, since the terminal device main body can provide the force to prevent the device from coming off, the binding tool may be a simple one that does not require any force to prevent the device from coming off.

In addition, to form the loop part, all you need to do is to insert the suspension cable into the cable insertion hole of the terminal device body and fasten the end part with a simple binding device that does not require any pulling force, so no special tools are required. , can be easily formed in the field. Furthermore, since the end portion of the hanging rope is hidden within the binding tool, there is an effect that the hanging rope can be operated smoothly without becoming tangled.
