Description

[Detailed description of the invention] Boat plate presser springs are attached to the left and right sides of the warp presser boat plate of a loom, respectively, to the lower mounting shaft for elastic traction, but they may break, and if the springs break, A major drawback is that the broken spring springs up due to its elasticity, gets entangled with the warp threads, and breaks the warp threads.

As shown in Fig. 3, the conventional boat board holding spring has a ring formed by extending the lower end of a spiral wound spring body, and a ring formed by rounding the prong end with a single line extending from the upper end of the spring body. was formed.

Therefore, since there are the above-mentioned drawbacks, the present invention aims to eliminate the drawbacks and obtain a spring for boat boards easily and inexpensively, which does not cut the warp even if the spring breaks and can be immediately replaced even if the spring breaks. That is.

In the present invention, the upper and lower ends of a spring 1 made of steel wire are formed into spiral winding rings 6 with two or more windings rising from each end. Then, the distal end of the winding ring 6 is pushed out, and the bases 7, 7 of the ring body 3 formed by two bent lines and the ring body 2 are inserted between it and the other winding ring. By pushing forward the ring body 3 or the ring body 2, the roots 7, 7 of the ring body and the ring body 2 can be inserted and multiplied into the circular space of the winding ring 6, and this action can be carried out in the reverse order. However, it is also possible to remove the ring body 2 etc. from the inside of the winding ring 6.

The spring 1 is a tube 5 made of a soft material such as vinyl chloride and has a length approximately twice that of the spring 1.
An annular body 2 housed within the tube 5 and connected to the lower end of the spring 1 is attached to the lower end of the tube 5 so as to pass through the lower end.

The extension range of the spring 1 is such that even at maximum extension, the upper end of the spring 1 does not come out of the opening of the tube 5, and even if it is cut, the spring 1 is unlikely to jump out of the tube 5, and even if it should. Even if something happens, the spring 1 will have finished its contraction operation at that time, and the spring 1 that has finished its contraction operation will not bite other objects.

In addition, as shown in Fig. 5, the present invention inserts hoop portions 4 at both ends of the boat board to create drooping tension, and since there is a further distance to the warp, in the event that the spring 1 pops out, the warp does not reach the warp. I will not bend down and bite this.

Further, even if the spring 1 is cut, the spring 1, ring body 2, and ring body 3 can be attached and detached by the winding ring 6, so that the upper and lower parts can be freely removed and the spring replaced.

However, the conventional method is extremely troublesome because the entire structure must be replaced.

Furthermore, since the synthetic resin tube 5 is coated with the spring 1 with a gap provided therebetween, it has no effect on the spring force of the spring 1, and is an extremely useful device as a spring for a boat board of a loom.
