Description

[Detailed description of the invention] This invention relates to an elevating device that moves an elevating type lighting device to a desired height, and aims to facilitate the assembly of a reinforcing plate provided at the end of the take-up reel and improve the assembly strength. That is.

The take-up reel of a conventional lifting device has a cross-sectional shape of a letter or a U-shape, and the inside is hollow to accommodate functional parts such as a mainspring, thereby reducing the size of the device.

The take-up reel is provided with a wire to cover the opening and serve as a lid for the functional components housed inside, a wire to be fixed, and a reinforcing plate to reinforce the end face of the take-up reel.

Conventionally, the take-up reel and the reinforcing plate were attached by passing a wire through the end face of the take-up reel and the reinforcing plate in a meandering manner. There was a drawback that the work was difficult to do because the position of the board was misaligned.

The present invention is intended to fundamentally eliminate the above-mentioned drawbacks, and will be explained below based on embodiments.

In the drawings, reference numeral 1 denotes a take-up reel made of synthetic resin and has locking portions 2, 2 having claws on its end surfaces.

Reference numeral 3 denotes a metal reinforcing plate which is attached to the end face of the winding rule 1.

This attachment is completed by inserting and locking the locking portion 2゜2 of the take-up reel 1 into the locking portions 4, 4, which are holes formed in the reinforcing plate 3, and temporary assembly can be completed. .

5 is a wire, and the winding start portion thereof is passed through a hole 6 formed in the end face of the take-up reel 1, and then passed through a hole 7 formed in the reinforcing plate 3.
further passes through the notch 8 of the reinforcing plate 3 and the take-up reel 1.
Pass through the notch groove 9 and hole 10 at the end of the take-up reel 1, insert into the pocket 11 at the end of the take-up reel 1, and then tie the knot 12.
This knot 12 is placed in the pocket part 11 and passed through the end face of the take-up reel 1 and the reinforcing plate 3 in a serpentine shape.
It is firmly attached to the end face of the locking member 2, thereby reinforcing the temporary assembly of the locking portions 2, 2 and the locked portions 4, 4 described above.

The wire 5 is then wound around the winding surface 13 of the winding rule 1.

The work of passing the wire 5 through the hole 7 etc. is performed using the reinforcing plate 3.
Although it is easier to attach the reinforcing plate 3 to the take-up reel 1, it is also possible to attach the reinforcing plate 3 to the take-up reel 1 after passing through the reinforcing plate 3 first.

Even in the latter case, if the reinforcing plate 3 is temporarily assembled on the take-up reel 1 after the work of threading the wire 5 is finished, the reinforcing plate 3 will not come off during the work of tightening the wire 5, making the work easier. .

Note that the convex portion 14 at the end of the take-up reel 1 is connected to the hole 7 of the reinforcing plate 3.
Furthermore, the convex portion 15 at the end of the take-up reel 1 fits into the notch 8 of the reinforcing plate 3, and the pocket portion 11 fits into the notch 16 of the reinforcing plate 3.

In FIG. 2, internal mechanical parts such as a spiral spring and a ratchet mechanism are shown, but their explanation will be omitted.

Further, a reinforcing plate 3' similar to the reinforcing plate 3 is attached to the other end surface of the take-up reel 1, and has a structure similar to that described above.

With the above configuration, the present invention has a take-up reel 1, a reinforcing plate 3,
3' is assembled with the locking part 2 and the locked part 4, and
Since the wire is passed through the take-up reel 1 and the reinforcing plates 3, 3' in a meandering manner, the assembly strength of the take-up reel 1 and the reinforcing plates 3, 3' can be greatly improved, and the assembly work is easy. It has the characteristic of becoming.
