Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a laminate holding device for pressing down laminates such as stacked boards so that they stick together and do not come apart.

[Conventional technology]

At a construction site, etc., when cutting or cutting an original board to obtain a board with the same shape as a board with a predetermined shape, the two boards are overlapped and then cut along the shape of the board with the predetermined shape. It is common to cut or cut with a saw or drill, but at this time, two
It is necessary to prevent the two planks from shifting, so a work assistant may hold the planks in place to prevent them from shifting, or they may be secured with wire, needles, or screw clamps. It is fixed to a table.

[Problem that the invention attempts to solve]

However, with the conventional method, a separate worker is required, the use of wire or needles damages the board and additional work is required to remove it, and additional work time is required. The problem with tools is that they may become loose due to swinging due to the use of the tool during cutting or cutting, and may become unusable.

[Means for solving problems]

This idea was developed in view of the above-mentioned circumstances, and its specific means include a fixed column fixed to the base plate, and a fixed column that is biased toward the base plate by an elastic body. a moving member that moves the moving member in a direction opposite to the base plate against a biasing force; It is constructed of a presser bar that is prevented from moving away from the base plate by engaging claws provided on the movable member with the formed teeth.

[Effect]

According to the above means, the stacked laminate is placed between the base plate and the presser bar separated from the base plate, the presser bar is moved toward the base plate and brought into contact with the laminate, and then the release lever is moved. Therefore, when the movable member is moved in the direction opposite to the base plate, only the movable member moves in the direction away from the base plate while the lower end of the presser bar remains in contact with the laminate due to its own weight. Next, when the separation lever is loosened, the moving member is urged toward the base plate by the elastic body. At this time, the claw provided on the movable member meshes with the teeth formed on one side of the presser bar and presses the presser bar toward the base plate by the elasticity of the elastic body, so that the laminated material is moved between the base plate and the presser bar. held by.

To remove the clamped laminate, it is only necessary to rotate the presser bar within the moving member to disengage the teeth and pawls, and then move the presser bar in the opposite direction to the base plate.

〔Example〕

Embodiments of this invention will be described in detail below based on the drawings.

As shown in FIG. 1, the laminate holding device 1 of this embodiment includes a base plate 2 having a predetermined shape and size;
An inverted L-shaped fixed column 3 is fixed near one end of the base plate 2, and a support cylinder 4 is fixed to the end of the fixed column 3 on the side parallel to the base plate 2. A moving member 6 that is biased in a direction, a separation lever 12 that moves the moving member 6 in a direction opposite to the base plate 2 against the biasing force, and a separation lever 12 that moves the movable member 6 in the direction opposite to the base plate 2, and The main structure is a presser bar 7 which is provided so that it can be moved away from and approached.

The moving member 6 is an L-shaped hollow member, and its vertical rod 6a is rotatably inserted in the support cylinder 4 in the direction of the base plate 2, and its horizontal rod 6b is urged toward the base plate 2 by the spring 5. This spring 5 is externally fitted between the parallel side of the fixed column 3 and the horizontal rod 6b of the center rod 9, one end of which is inserted into a hole 8 drilled through the parallel side of the fixed column 3. And this center bar 9
The other end side is fixed to the horizontal rod 6b, and a locking protrusion 10 is fixed to the tip protruding from the fixing column 3 on one end side, and a fixing column is further fixed to support the upper and lower ends of the externally fitted spring 5. A spring support 11 is externally fitted on the 3 side and the horizontal rod 6b side.

A lifting ring 12a formed at one end of the separation lever 12 is fitted onto the tip of the center rod 9, and a locking protrusion 10 prevents it from coming off upward. Furthermore, a presser plate 12b is formed at the other end of this separation lever 12, and this presser plate 1
2b and the lifting ring 12a are in contact with the upper surface of the parallel side of the fixed column 3, so that when the holding plate 12b is manually pressed in the direction of the base plate 2, the lifting ring 12a As a result, the center rod 9 is lifted up against the elasticity of the spring 5.

A mounting member 14 having a through hole 13 concentric with the through hole 13 formed in the vertical rod 6a of the moving member 6 is provided at the upper end portion of the moving member 6 that protrudes from the support cylinder 4.
is fixed. This mounting member 14 has both ends of a pawl 15 that engages with teeth 7a formed on one side of a presser bar 7 inserted into the through hole 13 so as to be able to approach and separate from the base plate 2. A protruding piece 16 is fixed to support it so as not to rotate in the direction of rotation. The tip of the claw 15 is urged toward the presser rod 7 by a spring 17 whose one end is supported by a protruding piece 16.

An abutting cap 7b that contacts the laminate A is provided at the lower end of the presser bar 7 on the side of the base plate 2, and an abutment cap 7b is provided at the upper end protruding from the through hole 13 of the mounting member 14, and a cap 7b is provided at the lower end of the presser bar 7 on the base plate 2 side. A rotating lever 7c is formed so as to be easily rotated within the hole 13.

The operation of this embodiment having the above configuration will be explained.

When holding a stacked laminate A between the base plate 2 and the presser bar 7, as shown in Fig. 2,
Operate the rotation lever 7c of the presser bar 7 to open the through hole 13.
As shown in FIG. 4, the other side of the presser bar 7 on which the teeth 7a are not formed is directed toward the pawl 15, and then the rotating lever 7c is moved in the direction opposite to the base plate 2. As a result, the presser bar 7 is lifted and a gap is created between the abutment cap 7b provided at the lower end of the presser bar 7 and the base plate 2, and the laminate A is inserted into this gap. Thereafter, when the rotary lever 7c is released, the presser bar 7 falls downward in the through hole 13 due to its own weight, comes into contact with the laminate A, and stops. In this state, by rotating the rotary lever 7c,
By rotating one side of the presser bar 7 on which the teeth 7a are formed, in the direction of the claw 15, one tooth 7a is formed as shown in FIG.
mesh with. Since the teeth 7a are urged toward the presser bar 7 by the spring 17, they mesh with any of the teeth 7a or come into contact with the presser bar 7 between the teeth 7a. Then, the separation lever 1
When the presser plate 12b of No. 2 is pressed in the direction of the base plate 2, the lifting ring 12a at the other end rotates upward around the support protrusion 12c, so that the center rod 9 is lifted up against the elasticity of the spring 5. The moving member 6 is also lifted up within the support cylinder 4 in the direction opposite to the base plate 2. However, since the presser rod 7 is only inserted into the through hole 13, it does not lift up, and the contact cap 7b at the lower end remains in contact with the laminate A due to its own weight. That is, in this state, the pawl 15 meshes with one or more teeth 7a above the teeth 7a of the presser bar 7 that are in mesh with each other. Then, when you release your hand from the presser plate 12b, the center rod 9 is urged downward by the spring 5, so the moving member 6
However, at this time, the claw 15 is engaged with the teeth 7a of the presser bar 7, so the presser bar 7 is pressed downward, that is, in the direction of the laminate A, and as a result, the spring 5 The laminate A is moved to the base plate 2 by the force of
and the abutment cap 7b.

To release the clamping of the laminate A due to the elasticity of the spring 5, either rotate the rotary lever 7c to disengage the teeth 7a of the presser bar 7 and the pawl 15, or temporarily release the separation lever 12. After pressing the press plate 12b and releasing the pressing force of the pawl 15 against the teeth 7a, the rotary lever 7c is rotated to release the pressing force.

[Effect of idea]

As is clear from the above explanation, according to the laminate presser of this invention, even if the laminate is placed between the presser bar and the base plate and the separation lever is pressed,
Since the laminate can be held down by the elasticity of the spring, even if the laminate vibrates, the pressing force will not loosen and the stacked state can be reliably maintained.
