Swings within the angle and slides on the support plate
In the prior art of a certain cutting cloth holding device, a fixing release handle is extended at an end of an arbitrary position fixing floating plate on a side where a plate-shaped elastic machine and a floating cloth holding plate are not provided; and In addition, the outer edge of the floating cloth holding plate always has a small width protruding portion as appropriate from the outer edge of the fixed cloth holding plate, and slides down without applying force to the arbitrary position fixing floating plate when the cloth is held. When the plate is brought into contact with the fixed cloth holding plate, the floating cloth holding plate and the fixed cloth holding plate abut only on the outer edge of the fixed cloth holding plate, and the space between the lower surface of the floating cloth holding plate and the upper surface of the fixed cloth holding plate is appropriately adjusted. Both of the preservation of the minute gap are the main means for solving the problem.

[0013] Under these two main means for solving the problems, the structural rigidity is further increased, and the position is fixed at will.
Position fixation without losing the degree of fixation when fixing the floating plate
In order to solve problems such as facilitating sliding of the floating plate for use , a supporting plate, a fixing cloth holding plate, and a fixing cloth holding formed so as to protrude from the fixing cloth holding plate in a direction in which the supporting plate extends. The plate back edge is integrally formed, and the plate surface area is extended around the boundary between the support plate and the fixed cloth holding plate back edge, and fixed at an arbitrary position.
Semakei portion is formed on the strut plate inserted range of titration, floating plate, if the longitudinal guide hole to migrate guiding the narrow neck Ru drilled in the post plate
In order to facilitate the member fitting, solid optionally position
The member from the narrow neck of the fixed floating plate to the handle for fixing release is
It has a thickness and shape that can be inserted into the vertical guide hole,
The distance from the upper end of the vertically elongated guide hole to the fixed cloth holding plate surface is from the edge of the floating cloth holding plate to the side edge of the arbitrary position fixing floating plate closer to the opposite side of the floating cloth holding plate. or a longer structure than the distance ranging, or the upper portion of the strut plate is slightly oblong shape than struts plate executives, Sui the lateral length shaped portion
Meaning the position fixing floating plate can be inserted a floating plate fitted hole is bored in horizontal, vertical guide hole is a structure which extends to the optionally position fixing floating plate fitted hole.

[0014] Note that the main solution, in the dependent issues solution, the plate-like bullet machine in the prior art as a leaf spring symmetrically mountain-shape, Kagigoana having a predetermined length at both foot of the mountain part of the prior art similar plate spring Are formed and hook projections are formed in both end regions of the floating cloth holding plate, and the leaf spring accumulates resilience in the direction toward the top of the chevron, while the hook springs project from the hook engagement holes to the hook projections. As a configuration to be fitted or as a means for solving a new problem, a leaf spring and a loose cloth holding plate are integrally formed.
The configuration that is molded may also Rukoto newly coupled <br/> the means of the problem solution.

Further, according to the present invention, in order to make it difficult for an undesired impact and sliding wrinkles to be applied to the cloth to be held when the cloth is fixedly held and released, a floating plate for fixing an arbitrary position or a part connected thereto is provided. shock absorbing means at optional position fixing floating plate release is provided, the specific means for solving the problems, optionally position
An end area having an insertion portion of the floating plate for placing and fixing or the floating plate for fixing the optional position with the support plate is made of a material having high flexibility and elasticity, and the material portion constitutes a shock absorbing means. either, or above shock absorbing means, solid optionally position
The structure is that of an ammunition interposed between the upper surface of the fixed floating plate and the upper end region of the support plate.

According to the above construction, the cloth to be cut is sandwiched between the fixed cloth holding plate and the floating cloth holding plate, and the floating cloth for fixing the arbitrary position is fixedly connected to the floating cloth holding plate via the plate-like elastic machine. Is slid in the direction of the fixed cloth holding plate in the direction of the support plate or the vertically long guide hole formed in the support plate, and the plate-shaped elastic machine is pressed from above so that the cloth is held between the two cloth holding plates.

At this time, a "f" -shaped free movement for fixing an arbitrary position is provided.
The plate receives an upward spring from the floating cloth holding plate and a plate-like elastic machine connected to the plate, and has a long side portion having an “ H ” shape, that is, a side having no insertion portion with the support plate. The plate is pressed upward.
And for optional position fixing floating plate can be遊揺at a predetermined angle, the moment occurs in the strut plate insertion portion, the solid optional position
The contact edge with the support plate on the upper surface of the fixed floating plate is the surface of the support plate.
Surface and at the same time on the lower surface of the floating plate
The contact edge with the support plate is pressed against the back surface of the support plate, respectively.
The floating plate for fixing the desired position is fixed and stationary. The operation so far is the same as in the prior art.

[0017] those optional position fixing floating plate is fixed stationary strut plate inserting portion, in the procedure turn releases the Sui
A lifting force is applied to a fixing release handle extending from an end of the floating plate for fixing a desired position on a side where the plate-shaped elastic machine and the floating cloth holding plate are not provided.

When a lifting force is applied to the handle for fixing and releasing, the floating plate for fixing the arbitrary position can swing at a predetermined angle, so that a force in the direction opposite to the rotational direction of the moment is optionally applied.
Joined to the support plate inserting portion of the position fixing floating plate, solid optionally position
The contact edge with the support plate on the upper surface of the fixed floating plate is the surface of the support plate.
Pressing on the surface and below the floating plate for fixing the optional position
The contact edge with the support plate on the surface was added to the back surface of the support plate
The pressing is lost instantaneously at the same time, so that the floating plate for fixing the optional position is released with the impact caused by the ejection of the plate-shaped ammunition, and the floating plate for fixing the optional position is drilled in the support plate or the support plate. The cloth, which has been fixed and held, can be removed from the two cloth holding plates.

The fixing and releasing of the floating plate for fixing the optional position is performed by attaching the fixing cloth holding plate to a portion having the function of a handle for fixing and releasing at the end of the floating cloth holding plate of the floating plate for fixing the optional position as in the prior art. Direction, that is, unlike the case of applying downward pressing, the lifting is performed by applying a lifting force to the fixing release handle extended to the end on the side where the plate-shaped elastic machine and the floating cloth holding plate are not mounted, hardwired ration plate, never directly adding pressing the sandwiched fabrics in loose fabric holding plate and optionally the position
For applying a rotational direction opposite to the direction of the force moment working on fixing the floating plate fixed at rest from behind across the strut panel optional position fixing floating plate, solid optionally positioned over the prior art
The force to be applied when the fixed floating plate is fixed and released is extremely small.

[0020] Thus, in the present invention, incidental prior art
The undesired impact, which is likely to be applied to the cloth to be clamped which occurred during the release of the floating plate for fixing the desired position , and the wrinkles which are likely to be generated due to the pressing of the floating cloth holding plate connecting portion of the floating plate for fixing the arbitrary position are remarkable. Less likely to occur.

Along with such an effect, unlike the conventional example, a portion having the function of a fixing release handle extends at the end of the movable position fixing floating plate on the side where the floating cloth clamping plate is provided. In addition, since there is no protruding portion near the cutting line at the time of cutting the cloth, the work in the cutting step can be performed very smoothly.

On the other hand, the means for solving the second main problem in the present invention, that is, the outer edge of the floating cloth holding plate always has a portion which projects a minute width appropriately from the outer edge of the fixed cloth holding plate, and is optionally provided when the cloth is held. When the floating cloth holding plate is slid down without applying force to the position fixing floating plate and the floating cloth holding plate is brought into contact with the fixed cloth holding plate, the floating cloth holding plate and the fixed cloth holding plate contact only at the outer edge of the fixed cloth holding plate. From the means of solving the problem of a structure in which a fine gap of an appropriate angle is reserved between the lower surface of the floating cloth holding plate and the upper surface of the fixed cloth holding plate, at the time of fixing and holding the fabric,
Conventionally, cloth clamping is mainly biased to the portion of the floating cloth clamping plate closest to the column and to the vicinity of the back edge of the fixed cloth clamping plate. The loosening of the floating cloth between the floating cloth clamping plate and the fixed cloth from the fixed cloth clamping plate to the clamped cloth or the outer edge of the fixed cloth clamping plate There is an effect that stronger pressurization is performed diagonally downward toward the inside of both cloth holding plates.

According to the means for solving the second main problem, when the paper pattern is placed on the upper surface of the cloth and the cloth is clamped by the fixed cloth clamping plate and the floating cloth clamping plate together, the clamping pressure applied to the cloth by the cutting line is obtained. Because, due to the elasticity of the paper pattern, the pinching pressure and the stress effect due to this are moderately weaker than at or near the outer edge of the fixed cloth holding plate, so even when cutting near the holding part of the elastic cloth, The undesired irregularities in the fabric cutting section that are likely to occur hardly occur.

As described above, the clamping pressure from the floating cloth clamping plate to the clamped plate from the floating cloth clamping plate or the fixed cloth clamping plate is equalized, or both cloth clamping plates are arranged on the outer edge of the fixed cloth clamping plate from the floating cloth clamping plate. By applying a stronger pressure diagonally downward toward the inside of the fabric, the stress of these pressurized fabrics produces a synergistic effect with the elasticity of the fabric, and the fabric is more inwardly directed toward both fabric holding plates. In order to obtain the force toward the fabric, the degree of clamping and fixing of the fabric is significantly increased as compared with the prior art, so that the displacement of the fabric and the falling off of the fabric are less likely to occur.

If the fine gap is set in accordance with the characteristics of the fabric, in particular, the elasticity, the air content per unit volume, etc., a more excellent state of the fixed holding plate of the fabric is realized.

Further, according to the present invention, the fixed cloth holding plate, which is a separate member, the back edge portion thereof, and a fixed connection of a screw or the like thereto.
Since the three members of the pillar plate fixed by the fixture are formed as an integral body, even if the fixing and holding by the floating plate for fixing the optional position and the repetition of the release are repeated, there is a conventional occurrence near the fixing joint. There is no easy and inconvenient swing gap.

The above three members were molded as one piece.
With only the thing, there is a tendency that plastic deformation is likely to be caused at the portion corresponding to the joint, but in the present invention, in accordance with the above configuration, the plate surface area is extended around the border of the strut plate and the back edge of the fixed cloth holding plate. Therefore, for the left and right impact applied to the support plate,
In addition to the fact that the member is unlikely to be deformed, aesthetically, there is an effect that a way of providing a design is opened in this plate surface area.

By adopting such a configuration,
Since the head or end of the screw does not protrude to the fixed cloth holding plate side, the edge of the cut cloth is aligned with the back edge of the fixed cloth holding plate, and the cut cloth does not become uneven.

In the present invention, an arbitrary position is fixed as in the prior art.
Titration, not so constructed that strut plate inserting hole of bored in the floating plate is inserted, Semakei portion is formed on the strut plate inserted range of optional position fixing floating plate, migration of the narrow neck since the elongated guide hole for guiding has a structure which is formed in the strut plate, inserted guide friction strut plates considerably smaller than in the prior art, optionally position
Up and down sliding of the stationary floating plate is also smooth. In addition, because of such a structure, the plate surface area can be extended around the boundary between the support plate and the back edge of the fixed cloth holding plate as described above.
Although the load on the narrow neck is certainly increased, the use of a reinforced material in this portion does not cause any particular problem.

The main components of the present invention are integrated.
A fixing member composed of a fixed cloth holding plate, a back detail thereof, and a support plate, which are formed by molding , and a floating cloth holding plate, a plate-shaped elastic machine, and a floating plate for fixing an arbitrary position , which are mutually connected. And the same applies to the prior art. However, from the viewpoint of production or maintenance, it is desirable that these two main members be easily mounted and interchangeable, and the present invention meets this demand.

That is, a member from the narrow neck portion of the floating plate for fixing the optional position to the handle for releasing the fixing has a thickness and a shape that can be inserted into the vertically long guide hole, and the surface of the fixed cloth holding plate is formed from the upper end of the vertically long guide hole. the distance up to the long long structure is than the distance from the edge of the floating cloth holding plates up to the optional position fixing floating plate side edge, and vertically the floating member with respect to the stationary cloth holding plates, optionally The floating plate for fixing the position is inserted through the vertical guide hole, the narrow neck is interposed between the holes of the vertical guide hole, and then the floating member is rotated to set the floating cloth holding plate almost parallel to the fixed cloth holding plate. The mounting is completed in a very simple procedure of sliding down the vertical guide hole.

When both the length of the floating cloth holding plate and the length of the fixed cloth holding plate are considerably longer than the length of the vertically long guide hole or the support plate, the upper portion of the support plate is slightly longer than the support plate trunk. Shape, and a free position fixing
Rotation plate is inserted can optionally position fixing floating plate inserted fitting holes Horizontal bored, if structure Vertical guide hole is extended to the optional position fixing floating plate inserting hole, fixing the floating member Even if it cannot be inserted vertically into the vertically long guide hole with respect to the cloth holding plate, the mounting is completed by holding the floating member horizontally, inserting it into the floating plate insertion hole for fixing the optional position and sliding down as it is.

The plate-shaped elastic machine is a leaf spring having a bilaterally symmetric mountain-shaped shape. As in the prior art, a hooked hole having a fixed length is formed at both skirts of the leaf spring, and a floating cloth is pinched. Hook protrusions are formed in both end regions of the plate, and the plate spring is fitted into the hook protrusions from the hook holes while accumulating resilience in the direction of the mountain top. Even or new
A means of problems solved, the leaf spring and the idler fabric holding plate and is one
Even in the case of a configuration molded as a body, the resilient direction of the plate-shaped ammunition and the above-described effects are substantially the same.

However, in the latter case, not only the resilient direction of the leaf spring is up and down, but also the resilient effect in the front and rear oblique directions occurs.
When combined with the means for solving the main problem of the present invention, it is slightly longer in terms of shock reduction at the time of fixing and releasing the floating plate for fixing the optional position and ease of fixing and releasing the floating plate for fixing the optional position . However, the former case, Yu for voluntary position fixing
If a material having a relatively large flexibility and elasticity is used for the narrow neck portion of the moving plate, the same effect as that of the latter can be obtained, and the degree of fixed clamping tends to be generally high because the direction of rebound is fixed.

In the present invention, an arbitrary position fixing floating plate or an optional position fixing plate provided at a portion connected thereto is provided .
Shock absorbing means when the idler plate release, i.e. specifically, Sui
It positions without fixing the floating plate meaning the end region having a insertion portion of the strut plate optional position fixing floating plate, a flexible and configuration of resilient strong material, the material portion occurs in the insertion portion Since it functions as a leaf spring against the moment that is present, a restraining force is applied to keep the moment in the reverse rotation direction, which causes an impact, to a small value, and the floating plate for releasing the floating position is released, which bounces upward. The impact of the time is greatly reduced.

In addition, the above-mentioned shock absorbing means is provided with an optional position fixing play.
Even in the case of a structure in which an elastic body is interposed between the upper surface of the moving plate and the upper end region of the support plate, the elastic body often becomes a flexible leaf spring in a concrete implementation stage. But voluntary
It has the function of directly suppressing mainly upward movement of the support plate insertion portion of the stationary floating plate .

In this manner, the optional position fixing play
By reducing the impact that occurs when the moving plate is fixed and released,
Undesirable impacts on the clamped fabric are considerably mitigated, so that undesired sliding wrinkles on the fabric and displacement of the stacked fabrics are substantially avoided.

As shown in FIG. 4 (c), the fixation of the voluntary position fixing floating plate 7 is released with an impact generated by the repulsion of the leaf spring 8, and the voluntary position fixing floating plate 7 is cut into the support plate 2. The cloth 10a which has been fixed and held between the fixed cloth holding plate 1 and the floating cloth holding plate 6 by sliding up and down the vertically long guide hole 5 can be detached from the two cloth holding plates.

However, the floating plate 7 for fixing the optional position slides up and down the vertically long guide hole 5 because the material near the narrow neck 7a is subjected to surface quenching, so that the elasticity, flexibility, Rich in resilience, and the shock of sudden sliding is considerably reduced.

[0054] Optionally position fixing releasing fixing the floating plate 7 is carried out by adding a lift with finger pressure to the fixing release for handle 9, Sui
It does not directly apply pressure to the leaf spring fixing portion 7b of the floating plate for fixing the desired position or the fabric 10a held between the fixed cloth holding plate 1 and the floating cloth holding plate 6, and the floating for fixing the arbitrary position.
A force in the direction opposite to the rotational direction of the moment acting when the plate is stationary is applied from behind the support plate 2 of the floating plate 7 for fixing the optional position, and the plate is released. Floating plate for fixing position
Narrow for cervical and less friction with the peripheral edge of the elongated guide hole 5, the force applied during the prior art as compared to the optional position fixing floating plate fixing released, suffice a very small force.

Therefore, in the present embodiment, the prior art
Optionally position fixing Yu in optional position fixing floating plate fixing release
The undesired impact that is likely to be applied to the held cloth caused by the sliding movement of the moving plate 7 and the wrinkles that are likely to be generated by the pressing of the floating cloth holding plate connecting portion of the floating plate 7 for fixing the optional position hardly occur.

In addition to the above-described functions and effects, since there is no projecting portion near the cutting line at the time of cutting the cloth as in the conventional example, the operation in the cutting step near the cloth holding portion according to the present embodiment can be smoothly performed. It becomes possible.

On the other hand, in the fixed holding plate of the fabric 10a, in this embodiment, the cloth holding is performed by the loose cloth by setting the minute gap E which is retained between the fixed cloth holding plate 1 and the floating cloth holding plate 6 when not in use. Pressure is not applied to the portion of the holding plate 6 closest to the column plate and to the vicinity of the back edge 1a of the fixed cloth holding plate 1, but to the other parts, especially to the vicinity of the outer edge of the loose cloth holding plate 6 and the fixed cloth holding plate 1. Is not weakened, or the clamping pressure is equalized over the entire surface, or a stronger strength is applied to the outer edge of the fixed cloth clamping plate 1 obliquely downward from the floating cloth clamping plate 6 toward the inside of both cloth clamping plates. Pressure is applied.

When the paper pattern 10b is placed on the upper surface of the cloth 10a and the cloth is held between the fixed cloth holding plate 1 and the floating cloth holding plate 6, the pressing force applied to the cloth 10a by the cutting line is as follows.
Due to the elasticity of the paper pattern 10b, the pinching pressure and the stress effect due to the pinching are appropriately weakened more than the outer edge of the fixing cloth holding plate or its vicinity. Therefore, even when cutting near the holding portion of the elastic cloth, the pinching stress is generated. Unfavorable unevenness in the close cloth cutting section hardly occurs.

As described above, the cloth 10a and the pattern 10b held by the floating cloth holding plate 6, the fixed cloth holding plate 1, and the like.
Nip pressure to become entirely uniform or, some have a fixed cloth holding plates 1
Is applied to the outer edge of the cloth 10 obliquely downward from the floating cloth clamping plate 6 toward the inside of both cloth clamping plates, so that the stress of the pressurized cloth 10a is reduced.
In order to produce a synergistic effect with the elasticity of a, and the fabric obtains a force F directed inward of both cloth holding plates, the fabric 10a
It is difficult for the present embodiment to fall off to the outside, and the degree of clamping and fixing is very strong.

The setting of the minute gap E retained between the fixed cloth holding plate 1 and the floating cloth holding plate 6 when not in use is described below.
Since it is set in accordance with the characteristics of the fabric 10a, particularly the elasticity, the air content per unit volume, and the like, an excellent fixed and sandwiched state of the fabric is realized.

And formed by bending or continuous forming.
A plate surface area 3a is provided on the periphery of the boundary between the back edge portion 1a and the fixed cloth holding plate back edge 1a.
Due to the extension of 3b, deformation of the integrally formed member hardly occurs in response to left and right impacts applied to the support plate 2. In addition, since the head or end of the fixing tool such as a screw does not protrude toward the fixed cloth holding plate, the edge of the cloth 10a is aligned with the back edge 1a of the fixed cloth holding plate, and irregularities are not found in the cut cloth. Does not occur.

In addition, the friction between the movable position fixing floating plate holding neck portion 7a and the arbitrary position fixing floating neck 7a is considerably small and the vertical sliding of the optional position fixing floating plate 7 is smooth. In addition, because of such a structure, the plate surface area can be extended around the boundary between the support plate 2 and the back edge 1a of the fixed cloth holding plate as described above. With respect to the increase in the burden on the neck portion 7a, since a strengthening treatment is configured by applying a surface quenching step, no particular trouble occurs in strength.

The fixing member and the floating member are set so that the floating member is perpendicular to the fixing cloth holding plate 1 and the floating member for fixing the optional position is provided.
The moving plate 7 is inserted into the vertically long guide hole 5 from the portion of the handle 9 for fixing and releasing, the floating plate narrow neck portion 7a for fixing the optional position is interposed between the vertically long guide holes 5, and then the floating member is rotated. The mounting is completed in a very simple procedure of setting the loose cloth holding plate 6 substantially parallel to the fixed cloth holding plate 1 and sliding down the vertically long guide hole 5. The disassembly is only the reverse procedure, and it is very simple as well as the mounting.

[0064] Optionally the position fixing floating plate clamping neck 7a, because you have a quenching process, a flexible, elastic, and since has become a material rich in restoring force, for the moment occurring in the interpolation fitting portion It functions as a leaf spring, which applies a restraining force to keep the reverse rotational moment, which causes an impact, at a small value, thereby fixing and releasing the floating position fixing floating plate 7 which rebounds upward. The impact of the time is greatly reduced.

In this manner, the impact generated at the time of fixing and releasing the floating plate for fixing the arbitrary position is reduced, so that the fabric 1
0a, the undesired impact applied to the pattern 10b is considerably reduced, and as a result, undesired wrinkles are given to the fabric 10a,
Even if the fabrics 10a are piled up fabrics, there is little chance of misalignment.
