Description

[Detailed Description of the Invention] This invention relates to a support stand, and particularly relates to an improvement of a tie support stand equipped with a cloth clamping device that can be operated with one hand.

Traditionally, when sewing or doing handicrafts, a part of cloth is held in place and stretched with a hook tied to it and a stand is used.

That is, as shown in FIG. 1, the box base 1 is simply a vise, and its U-shaped body 2 is fixed to a work table 4 with a tightening screw 3, and a string 5 is connected to the end of the tightening screw 3. The needle movement is performed by tying a hand strap 6 and holding the cloth 7 in its mouth, but when changing the direction of hand movement, etc., when re-holding the cloth 7 in a different position, Since both hands are required to open and close the holder and to hold the cloth 7 in the grip, it is necessary to take one's hands off the needle 8, which may cause the needle 8 to fall out or the thread 9 to fall out from the needle. , causing a decrease in work efficiency.

In addition, when the cloth is spread flat on the chifur and the hands are moved horizontally, the hook 6 is tied to the part of the stake 1 that rises from the table surface via the string 5, so it is unstable and unstable. Conventionally, this required extra effort such as placing a weight on the cloth in such cases.

This idea was made to solve the above-mentioned conventional problems; it allows cloth to be clamped flat on the table surface without using a hook, and the clamping and release can be done with one hand. This is an attempt to provide a one-touch tying table.

Next, this invention will be explained with reference to the illustrated embodiment! 2.3
, 4, 5.6, the U-shaped fixing body 10 is assembled with a tightening screw 12 screwed into the lower side 11, and the upper side 13
The movable metal fitting 15 and the coil spring 16 are fitted to cover the main body 10 from the back side, and constitute a vise for holding the table 4 etc. between the inner surface of the main body 10 and the upper bracket 14 of the tightening screw 12. A serrated claw piece 18 attached to the main body 10 via a leaf spring 17 constitutes a stand for the one-touch knot of the present invention.

The end of the tightening screw 12 is formed into an annular knob 19, so that when it is fixed to a table upside down from the illustration, it can be used in the same way as a conventional knot holder.

As shown in FIG.
are screwed together.

In the illustrated example, the upper part 13 of the fixed body 10 has a planar shape of L.
It has a protruding part 21 in the shape of a letter, and its inner surface faces the receiving metal fitting 14 and serves as a vice clamping surface for holding a chiffle or the like therebetween, and the outer surface (upper surface) is covered with anti-slip rubber 22. It is being

The body part 23 between the upper and lower sides of the fixed body 10 has a slide guide elongated hole 24 at the top and a claw exposing hole 25 at the bottom. A serrated claw piece 18 is supported by a leaf spring 17 to which a portion is fixed, and a serrated claw piece 18 is disposed so that the claw teeth protrude from the back surface of the main body body.

Additionally, both sides of the flat end of the claw piece exposing hole 25 are formed into wide portions 26 having a width larger than the width of the movable metal fitting 15 for fitting and assembling the movable metal fitting 15, which will be described later.

The movable metal fitting 15 has a similar planar shape facing the upper part 13 of the fixed main body 10, and of course also has an overhang 2γ.
8, and a lower part 29 having a width that can be inserted from the wide width part 26, and thus has a U-shaped shape and is fitted over the fixed main body 10 from the back side as shown in the figure.

The lower part 29 of the movable metal fitting 15 has recesses 30 on both sides of its base (FIG. 5), and the recesses 30 fit into both edges of the claw exposing hole 25 when the fixed body 10 is engaged with the fixed body 10. Therefore, the movable metal fitting 15 can be slid up and down with respect to the fixed main body 10 in a fitted state.

In order to regulate the vertical stroke range of this slide and to guide the slide, a headed bolt 31 is inserted into the elongated hole 24.
It is screwed into the movable main body 15 from the inner side through.

There is an opening 3 in the body 32 of the movable metal fitting 15 in the lower part of the bolt 31 into which the claw of the serrated claw piece 18 enters.
3 is provided, and engagement teeth 34 that mesh with the claws of the claw pieces 18 are provided at the lower end thereof in the form of a bridge.

Furthermore, an opening 35 is provided from the lower part of the engagement tooth near the tip of the lower part 29, and the opening 35 functions as a hole through which the tightening screw 12 passes, as shown in FIG.

A coil spring 16 is disposed between the lower legs 11 and 29, and the movable metal fitting 15 is elastically biased upward by this coil spring 16.

The girder and stand of the present invention having the above-mentioned configuration is used by being fixed to a table upside down from the conventional example (FIG. 1), as shown in FIG.

That is, the table 4 is held between the upper end 13 of the main body 10 and the upper end of the clamping screw 12 and the receiving metal fitting 14, and the tightening is fixed by the tightening screw 12, and the upper end 13 of the main body and the movable metal fitting 15 are fixed. When the movable metal fitting 15 is pushed down against the coil spring 16 by placing the cloth 7 between it and the upper part 28, both upper parts 1
During 3.28, the cloth 7 is clamped through the rubber 22, and the movable metal fitting 15 is pressed down so that its engaging teeth 34 engage with the claws of the serrated claw pieces 18 at the depressed position, and the movable metal fitting 15 does not return upward. ,
Therefore, not only can the cloth 7 be clamped with one hand, but also the clamping position is almost at the height of the top surface of the table 4, and the clamping is done at a fixed point, which is more stable than the conventional clamping method using a rope. This allows for clamping.

To release the above-mentioned clamping, the lower end button 36 of the serrated claw piece 18 is pushed in using the elasticity of the leaf spring 170, so that the claw retracts into the interior, so that the engaging teeth 34 are disengaged from the claw piece 18, and the coil is released. Due to the elasticity of the spring 16, the movable metal fitting 15 returns upward, opening the upper part 13.29.

Therefore, this release operation can also be performed with one finger of one hand.

Furthermore, by providing the protruding parts 22 and 27 on the upper part 11.29 and peeling the planar shape into an L-shape, the protruding parts 22 and 27 allow the cloth 1' to be held in different directions as shown in FIG. .2
7, the girder can further increase the usability of the stand.

As mentioned above, the one-touch girder of the present invention can stably grip the cloth without using a conventional beam, and the gripping height can be lowered to the same level as the work table surface. Therefore, it is convenient when sewing with the fabric laid flat on the work table, and since you can operate the grip and release with one touch with one hand, you do not have to take the needle away from your other hand. This eliminates any possibility of deterioration in work efficiency.
