Description

[Detailed description of the invention] This invention relates to a toy loom that weaves plainly by intersecting one warp and one weft.

Conventionally, this type of toy loom has been equipped with two distaffs at the front and rear ends of the loom frame, on which a large number (for example, about three warps) of warp threads are wound and stretched at parallel intervals. Two thread guide plates with thread insertion holes for vertically moving every other warp thread are arranged adjacent to each other in the middle of the machine frame located between the bobbins, and the thread guide plates can be moved up and down alternately by operating a lever. While moving
It is known to have a structure in which the weft threads are passed between the vertical threads of the warp threads for plain weaving, but in this conventional weaving machine toy, the distaff is used to tie and secure a large number of warp threads one by one. However, the warp yarns had a disadvantage in that attaching the warp yarns to the distaff pin was troublesome and time consuming.

This invention was made to solve the above-mentioned conventional drawbacks, and a rubber plate with thread insertion cuts for fixing the ends of the warp threads with elastic force is attached to the outer periphery of the distaff pin, facing in the length direction. The gist of this invention is to enable the ends of a large number of warps to be easily and reliably fixed to the spool pin.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, reference numeral 1 indicates a machine frame molded from plastic, and a pair of left and right brackets 2a, 2b, and 3 are attached to the front and rear ends of the upper surface of the machine frame.

A pair of left and right upright plates 5°6 having two vertical guide grooves 5aw 5b and 6a, 6b are protruded from and spaced apart from each other on the machine frame intermediate platform 4 which is closer to the sides a and 3b. .

Incidentally, at the upper ends of the bracket pairs 2at 2b, 3a, and 3b, there is a shaft stopper 1at 1be 8 that closes the U-shaped bearing part.
at 8b is fixed with screws.

Reference numerals 9 and 10 denote a pair of front and rear pincushion pins that are rotatably supported by the pair of brackets 2a, 2b and 3at3b, each having a screw 1 at both ends.
1, a rotary operation knob 12 and a screw tightening knob 13 screwed together.
It is supported as shown in FIG. 5 so that rotation can be stopped by tightening the screw, and it can also be rotated by loosening the screw tightening knob 13.

These pincushion rods 9 and 10 are made of rectangular rods with a cross-sectional shape as shown in FIG. ，
17 is formed.

The rubber plates 14 and 15 are relatively thick band-shaped ones, and have thread insertion cuts 14 that protrude from the outer peripheral surfaces of the distaff pins 9 and 10 and fix the ends of a large number of warp threads A with elastic force.
a* 15a are cut at equal intervals in the length direction.

18.19 are two thread guides having a thread insertion hole 20 and a thread vertical movement elongated hole 21 for moving up and down every other warp thread A, which is wound and stretched between the bobbins 9 and 10. The vertical guide grooves 5ay6a, 5b, 6b of the machine frame upright plates 5, 6 are plates.
The racks 22, 23 and pinions 24 are interlocked to alternately move up and down.

Note that the guide plates 18 and 19 are thread guide stoppers 18.
The thread guide plate 18.1 is provided with thread guide lids 2B and 29 that are locked by the thread guide lids 2B and 29, which are locked by the thread guide lids 2B and 29 held by the thread guide lids 2B and 29, which are opened to both sides with the pivot pins 30.31 as fulcrums.
Insert the warp threads A one by one into the shallow grooves 20a and the deep grooves 21a that coincide with the threading direction of No. 9 as shown in FIG.
The structure is such that the thread is threaded by covering the threads B and 29 and locking them with the stoppers 18a and 19a.
0a and the protruding pieces 20b of the thread guide lids 2B and 29, the thread vertical movement elongated holes 21, which are secured in the form of a small rectangle and coincide with each thread insertion hole 20 in the threading direction, are located on both guide plates 1.
It is formed by the deep grooves 21a of the thread guide lids 28 and 29, and the cut grooves 2mb between the protrusions of the thread guide lids 28 and 29 (clearly shown in FIGS. 6 and 7).

The racks 22 and 23 are integrally provided at the center of the lower side of the yarn guide plate 18 and 19, projecting downward through the slit holes in the intermediate platform section 4 of the machine frame, and extend from the inner guide strips 25 of the platform section 4.
, 26 as shown in FIG.

The pinion 24 that meshes with the opposing teeth of both racks 22 and 23 is connected to a square shaft 27 that is rotated by a rotation lever 27.
It is fixed at a.

The rotating lever 27 is located on both sides of the machine frame 1, and has a built-in spring component 37 as a locking/disengaging means for locking the vertical movement limit of the thread guide plate 18, 19 (see FIG. 2). .

Note that the reference numeral 38 shown in FIG. 3 designates one of the two engaging step portions exposed to the outside with which the spring end hook portion 37 at 37 b of the spring component 37 is removably engaged. shows.

Further, reference numeral 38 shown in FIG. 1 is a weft thread threading tool, 39 is a comb-like tightening plate, and 40 is a rod-shaped cover having a U-shaped cross section that is fitted on the outside of the rubber plate 15 of the thread winding pin 10.

For example, the length of the item you want to weave is 1rrL.
In this case, prepare the required number of warp threads A (for example, 3 pots) cut into lengths (length of about 1.2rrL) and wrapping paper (not shown) cut to the desired length and width for weaving. Set it as follows.

■ First, open the thread guide lids 2B and 29 on both sides and rotate the rotating lever 27 to the intermediate position to remove the thread guide plate 18.
．． Leave 19 at the same height.

■ Cut one end of the warp thread A beforehand and insert it into the rear distaff 1.
Insert and fix into the cut ends 15a of the rubber plate 15 one by one from the end of the rubber plate 15.

■ All the warp yarns A inserted into the rubber plate 15 are passed through the yarn guide plate 1.
Insert them one by one into the grooves 20a and 21a of Nos. 8 and 19 from the end.

■ When all the warp threads A have been threaded, open the thread guide lid 28.
29 is closed and latched with thread guide stoppers 18a and 19a so as not to come off.

(2) Fix the end of the wrapping paper (not shown) prepared earlier to the rubber plate 15 of the thread winding pin 10 by inserting the cover 40, making sure that the end of the threaded warp thread A does not get mixed up.

■ Loosen the screw tightening knob 13, and while lightly pressing the warp thread A with your left hand, turn the thread winding pin 10 clockwise (clockwise) with your right hand, and wind the warp thread A together with the wrapping paper around the thread winding pin 10. Go.

(2) When this winding is completed to the point where the warp yarn A can be stretched tightly between the bobbin pins 9 and 10, the knob 13 is tightened to fix the rear bobbin pin 10 so that it does not rotate.

(2) Set the rubber plate 14 of the front spool pin 9 to a position protruding diagonally upward, and then tighten the screw tightening knob 13 of the spool pin 9.

In this state, the other end of the warp thread A is inserted into the cut end 14a of the rubber plate of the thread winding pin 9 and fixed so that each warp thread A is taut.

③ After completing the preparation work ② to ② above, move the lever 27 to check whether the warp threads A have come off or not, and then perform plain weaving using the following weaving method.

[Phase] Thread the threading tool 38 (two large and small sizes are available, but the larger one is shown as an example in Fig. 1).
(not shown) several dozen times.

0 By operating the rotation lever 27, the two thread guide plates 18
．． 19 is moved up and down to displace every other warp thread A to create a difference in height.

@ Threading tool 38 is placed in the upper and lower spaces where the warp threads A are alternately displaced.
from the right side to the left side, and the woven weft thread is passed through the tightening plate 39.
Tighten it toward you.

0 Next, turn the lever 27 in the opposite direction, move every other warp yarn upside down, pass the threading tool 3B through the gap from the left side to the right side, and then pass the weaving weft yarn through the tightening plate 39.
Tighten it toward you.

QΦ From now on, this operation is repeated to finish the weaving in order. In this case, when the weaving is completed to the vicinity of the thread guide plates 18 and 19, the woven fabric is wound onto the distaff 9 and the same plain weaving operation as above is carried out again. It is natural to do this.

The toy loom of this invention has the structure described above, and a rubber plate with thread insertion cuts is attached to a distaff that winds and tensions a large number of warp threads. This has the advantage that the warp threads of a book can be fixed very easily and reliably using rubber elasticity.
