A moving body 14, an elastic body 15 that elastically deforms and urges the moving body 14 in the length direction of the step tree, and a cord 16 that pulls the moving body 14 in a direction opposing the elastic recovery force of the elastic body 15. , A guide 17 for guiding the cord 16 in a direction intersecting the length of the step tree, a stopper 19 having a recess 18 for fitting the cord 16, and a foot switch 2
0, the elastic body 15 and one end of the cord 16 are connected to the moving body 14, and the other end of the cord 16 is guided to the lower side of the step tree through the guide 17 to the rotating body 11. The stopper 19 is attached to the tread 12 at a position where the recess 18 is fitted into and retracted toward the cord 16 and engaged with the moving body, and the electric device 13 is connected to the tread 12. It is characterized by comprising a motor 21 for rotating the rotating body 11 in response to an instruction signal from the twelve foot switch 20.

[0006]

The present invention will be described below with reference to the illustrated embodiments. The tip of the stepper 12 is pin-joined to a support shaft 26 supported in the width direction of the hand loom so as to swing and rotate, and an intermediate portion thereof is connected to a heddle 27, and a leaf spring is provided at its rear end. A foot switch 20 which is elastically biased (not shown) and whose tip is pushed up is pin-joined so as to swing and rotate. A spiral spring 15 having a cylindrical moving body 14 joined to the tip thereof is attached to the rear end of the stepping tree 12.
A cord 16 is joined to the tip of 4. Code 16
Is pulled out to the lower side of the tread 12 through a guide 17 provided in the middle portion of the tread 12, and when the tip of the cord 16 is pulled, the moving body 14 is pulled out to the guide 17. There is. Directly below the guide 17, there is a rotating body 11 attached to a rotary shaft 28 that is driven to rotate in the forward and reverse directions by a motor 21, and the tip of a cord 16 pulled out from the guide 17 is joined to the rotating body 11. For this reason, when the rotating body 11 rotates forward, the cord 16 moves
1, the movable body 14 is pulled out to the guide side 17, and the rotary body 11 is reversely rotated, the cord 16 is rewound and the movable body 14 is pulled back by the elastic recovery force of the spiral spring 15.

A stopper 19 projects downward from the tip of the foot switch 20. The lower end of the stopper 19 is a recess 18 that fits into the cord 16. When the foot switch 20 is depressed, the cord 16 fits into the recess 18, and when the foot switch 20 is depressed further, the switch is turned on. The motor 16 rotates forward and the cord 16 is wound around the rotating body 11. When the cord 16 is fitted into the recess 18, the moving body 14 pulled by the cord 16 is caught by the stopper 19 and stops, and the rear end portion of the tread 12 is as much as the cord 16 is wound into the rotating body 11. The cord 16 pulls it toward the rotary shaft 28, and as a result, the stepper 12 swings around the support shaft 26 and descends, forming an opening 29 between the warps.
A sensor 23 is installed below the footstep 12. The sensor 23 is a safety device that stops the motor 21 by detecting the abnormal fall of the stepping tree. This type of sensor may be installed on the upper side of the tread 12, so that the tread 12 that is inadvertently pushed up can be detected. In addition, a sensor that stops the motor 21 when pets get in is installed under the tread 12, so that the pet may fall under the tread 12. It is better not to.

A large number of rotating bodies 11 corresponding to a plurality of step trees 12 are attached to the rotating shaft 28, and these rotating bodies 11 rotate integrally. Therefore, when the switch 20a of the step tree 12a necessary for the opening is stepped on, all the rotating bodies 11 rotate simultaneously, but the switch 20b is not stepped on the other step tree 12b. The body 14 is not caught by the stopper 19 but is pulled by the cord 16 and moves to the guide side 17. As a result, those unstepped treads 12b are not attracted to the rotation shaft side 28 and maintain their original state apart from the rotation shaft 28, and therefore the healds 27 connected to these treads 12b descend. do not do.

Reference numeral 22 is a solenoid, and reference numeral 24 is a hand push switch provided for each step tree. The solenoid 22 and the motor 21 of each step tree can be operated by a push switch 24. That is, the push switch 24
When the switch is turned on, the stopper 19 is attracted to the solenoid 22, and the moving body 14 is caught by the stopper 19, and at that time, the motor 21 rotates to turn on the footstep 12a corresponding to the hand push switch 24 which is turned on. Descend,
The remaining treads 12b corresponding to the remaining hand-operated switches 24 do not descend, and an opening 29 is formed between the warp threads corresponding to the descended treads 12a and the warp threads corresponding to the treads 12b that do not descend. Become.

Reference numeral 25 is a release switch for releasing the ON state of the foot switch 20 and the hand push switch 24 to reversely rotate the motor 21. Thus, the opening 29 is formed by either the foot switch 20 or the hand push switch 24, and is closed by the release switch 25. In that case, the motor 21 is
When the cord 16 is reversely rotated and is rewound, the cord 16 is pulled by the spiral spring 15 and the moving body 14 is returned to the original position. As such, the cord 16 is in a tensioned state in which its rear end is pulled by the spiral spring 15 via the moving body 14 and always extends straight. A counter is incorporated in the motor 21, and the motor 21 rotates forward and backward by the number of rotations required to move the tread 12 up and down and stops.

In the event of a power failure, the tread 12 can be deeply depressed to form the opening 29 as in the conventional handloom, and in that case, the cord 16 is simply loosened to allow the tread 12 to move.
Does not interfere with the exercise of.

The cord 16 according to the present invention is the moving body 14
Anything that can be flexed such that the direction is changed from the length direction of the tread 12 to the rotation shaft side 28 with the guide 17 as a boundary, and rope (string), wire, chain (chain), etc. is used for that You can do it. Further, the elastic body 15 in the present invention, as shown by the spiral spring 15, returns the moving body 14 pulled out by the cord 16 in the longitudinal direction of the tread 12 to the original position. Any material that can be elastically deformed in the depth direction may be used, and a rubber string may be used instead of the spring.

FIG. 4 exemplifies a case where a coil spring is used as the elastic body 15. The moving body 14 is guided and moved by a pipe rail 30 provided in the length direction of the step tree. There is. Two coil springs 15a and 15b are fitted on the pipe rail 30 so as to sandwich the moving body 14, and when the moving body 14 moves to the guide side 17, the front coil spring 15a pushes back and the rear coil spring 15b pulls back. Thus, the moving body 14 is elastically biased.

The stopper 19 may be any one that prevents the movement of the moving body 14 that is pulled by the cord 16 and moves. Therefore, the stopper 19 is like a projecting branch that appears and disappears along the moving path of the moving body 14. May be. FIG. 5 illustrates a stopper 19 operated by a manual switch,
The solenoid 22 is adapted to project and retract toward the passage in which the moving body 14 moves.

In the handloom equipped with the stepping device of the present invention, the shedding motion can be automatically controlled by incorporating the hand-push switch 24 and the release switch 25 in the computer.

[0016]

According to the present invention, the footstep 12 of the footstep 12 is lightly stepped on the foot switch 20 attached to the footstep 12 or the footswitch 2.
It is operated only by pushing 4, and the operation of the opening movement of the warp threads is semi-automated, thereby reducing the labor of hand-weaving work and obtaining a hand-loom suitable for a limb training device for physically handicapped persons.

The opening 29 is kept open until the foot switch 20 is lightly stepped on or the manual switch 24 is pressed and then the release switch 25 is pressed, so that the weft insertion operation can be carried out easily over time.

The cord 16 does not hinder the movement of the tread 12 by merely loosening when the tread 12 is deeply depressed, and the opening 29 is formed by such a deep depression of the tread 12, so that in the case of power failure It can be used in the same manner as a hand loom, and the function of the hand loom is not impaired by implementing the present invention.

Since the stepping device of the present invention can be made compact by incorporating a foot switch, a stopper, a moving body, a cord, a solenoid, etc. into the stepping tree, the practicing of the present invention does not make the handloom difficult to handle.
