Description

[Detailed description of the invention] The present invention relates to a guide device for inserting the end of a drawstring into a pulley case as shown in Japanese Utility Model Applications Nos. 57-162791 and 57-162792.

In order to hang the folded part of the drawstring around the pulley of the motor mount as described above, it is necessary to pass both ends of the drawstring from behind the pulley on both the left and right sides, and then insert it inside the left and right throttling wheels. It is quite difficult to insert a rigid pull string such as a rope into the inside of the throttle wheel through the outside of the pulley while bending it in the middle because it may bounce during the operation.

This invention was devised for the purpose of making it easier to insert the drawstring by providing a guide device between the pulley and the throttle wheel.The structure is explained with reference to the drawings. Figure 1 shows the plane of the pulley case of the invention. 2 is a sectional view taken along the line A-A in FIG. 1, and FIG. 3 is a perspective view of the seat plate provided with a guide.

In the drawings, reference numeral 1 denotes a pulley case body, which is shaped like a box elongated in the front and back direction with the front, rear, and upper surfaces open, and has an insertion part 2 for the end of the curtain rail 11 in the front part, and a flat pulley 3 in the center of the rear part. The left and right throttling wheels 4, 4 are pivoted between the pulley and the insertion part, and the seat plate 5 is inserted between the pulley 3 and the pulley case body 1, and the seat plate 5 is attached to the case body. At the same time, the left and right guide plates 6, 6 are erected so as to be substantially parallel to the outside of the drawstring that is hung between the pulley and the throttle wheel at positions opposite to the left and right sides of the front part of the pulley on the seat plate. It is something. In the figure, 12 is a motor mounting surface, 13 and 14 are fixed plates, and 15 is a wire rope presented as an example of a drawstring.

In order to fix the seat plate 5 on the case body, there are other means such as gluing or screwing, but as shown in the figure, a fitting part 7 for the pulley shaft seat is provided in the center of the seat plate, and the left and right dimensions of the plate are provided. If it is made the same as the dimension between the insides of the case body, rotation can be prevented and the left and right guide plates 6, 6
is held in place.

To attach the drawstring to the proposed pulley case, first
As shown in the figure, when both ends of the drawstring 15 are pushed into both left and right sides of the pulley 3 from the rear of the case, both ends of the string are guided by the guide plates 6, 6, pass through the opposite sides of the throttle wheels 4, 4, and pass through the front of the pulley 3. It will be pulled out, so you can just insert it into the curtain rail.

As mentioned above, the pulley case of this invention makes it easy to hang the pulley and the throttle wheel, and especially when hanging a rigid wire rope etc. It has the advantage of being able to operate accurately without having to judge where the tip is going.
