Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a clamping tool that is attached to a sheet material such as cloth, leather, paper, or a synthetic resin board and used to clamp an object.

[Prior art] A clamping tool conventionally used for paper clipping, etc. consists of a base fixed to a substrate such as cardboard and a presser joined in a hinged manner, and the presser is moved in a direction overlapping the base using a coil spring or the like. A biased type is common, but since a spring is required to bias the presser, the structure tends to be complicated and thick.

As an improvement to this, a plate-shaped pedestal and a plate-shaped presser are rotatably connected in a hinged manner by a shaft part provided on one side and a support part provided on the other side. However, a holding tool has been proposed in which an object is held between the base and the holding tool (Japanese Patent Application No. 57-095630 (Japanese Unexamined Patent Publication No. 58-45097)). This clamping tool separates the joint end of either one of the pedestal and the presser into a plurality of parallel strips by a plurality of cuts made from the end toward the middle section, and these strips are separated into a plurality of parallel strips. At least one of the strips is an elastic piece (abutment plate part) that bends into a cantilever shape when subjected to an external force, and the other strip is a shaft part or a support part that is a coupling device, and the above-mentioned pedestal and The other of the holding devices is provided with a coupling device on the opposite side that is coupled to the coupling device, and is provided with a protruding piece that contacts the elastic piece and receives a reaction force from the elastic piece in a direction to clamp the article. Become.

[Problems to be solved by the invention] The hinge-type clamping tool described above can be made relatively thin, but the clamping force for clamping the article depends on the elasticity of the strip-shaped elastic piece (the contact plate part). Therefore, there was a problem in that the clamping force was not sufficient and the shaft part easily came off from the support part during opening and closing operations.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a clamping tool having the following configuration. That is, the clamping tool according to the present invention includes a first plate serving as a pedestal and a second plate serving as a presser, and the end of the first plate is formed by a vertical cut. It is divided into a plurality of strip-shaped small pieces, and at least one of these small pieces has its tip curved into a gutter shape to serve as a support part, and the other small pieces adjacent to this support part serve as a flat plate-like backing part. None, a lateral cut is made in the end of the second plate to form a shaft that fits into the gutter-like recess of the support, and the first plate and the second plate are connected to each other. in a clamping tool in which a shaft portion, a support portion, and a contact plate portion are connected in a hinged manner so as to be freely openable and closable, and a reinforcing plate for supporting the contact plate portion is fixedly provided on the back surface of the first plate body. In addition, the reinforcing plate is characterized in that a stepped portion is formed so that a portion outside the free end of the abutment plate portion is raised toward the surface side of the abutment plate portion.

[Function] Since the reinforcing plate that supports the contact plate is provided on the back surface of the first plate, the contact plate, which is an elastic piece, is reinforced and a sufficient clamping force can be obtained. In addition, since a stepped portion that protrudes toward the surface of the plate portion is formed at the portion where the free end portion of the abutment plate portion is located, deviation of the shaft portion is less likely to occur.

[Example] Figure 1 and the following figures show examples of the present invention. This clamping tool 1 has a base 2 that is a first plate, a presser 3 that is a second plate, A reinforcing plate 4 is integrally connected to the back side of the pedestal 2 by caulking. The pedestal 2 is made of an elastic metal plate (in this example, a SUS301 stainless steel plate, hardness 500 HV, tensile strength 180 Kgf/mm ² ). , 5, ... are inserted, and these cuts 5, 5, ... make the end part into a rectangular 2
It is divided into two contact plate parts 6, 6 and three support parts 7, 7, 8 curved in the shape of a gutter. A caulking hole 9 is bored in the fixing plate portion 2a of the base 2.

The reinforcing plate 4 is formed to be longer than the pedestal 2, and a stepped portion 4a is formed at the free end of the abutment plate portion 6 so that the tip thereof bulges toward the surface of the pedestal. Further, two reinforcing grooves 4b, 4b are formed in the reinforcing plate 4 in the vertical direction, with the pedestal side being concave and the back side being convex.

The presser 3 consists of a core material such as a metal plate and a covering layer, most of the core material being the plate body 3a, and the connecting end 3b to the pedestal 2 being bent in a dogleg shape (in the illustrated example, θ=approximately 120 Every time). At the above joint end,
Lateral cuts 10, 10 are provided from both sides, and an intermediate cut 11 is provided on the same line at a distance from these cuts 10, 10. In addition,
A cutout portion 11a that further cuts into the plate portion 3a side is provided at this intermediate cutout 11 portion. A portion on the distal side of these cuts 10, 11, 10 serves as a shaft portion 12 for coupling. The shaft portion 12 is connected to the main body of the presser 3 by two legs 13, 13, which are the space between the cuts, and the end edge 12
a is formed as a straight line.

The plate portion 3a of the presser 3 is provided with a coating layer 15 made of a rubber material. The covering layer 15 has a height of 1
Although minute protrusions 15a for preventing slippage of less than mm are integrally formed, these protrusions 15a are not necessarily necessary. The covering layer may be formed of a synthetic resin other than rubber material, and may not be provided depending on the case. A plurality of round holes 17 are bored in the plate part 3a, and the coating layers on both sides are connected through the round holes 17, so that the adhesiveness is high.

A plurality (four in the figure) of cylindrical projections 20, 20, . This protrusion 20 has an outer diameter and a height of 3 to 5 mm.
It is preferable that The shape of the projection may be a conical projection 20' as shown in FIG. 3, or may be prismatic or other shape.

As shown in FIG.
By fitting between 7 and 8 and the contact plate parts 6 and 6, they are connected in a hinged manner so that they can be opened and closed. The clamp 1 thus obtained is used by fixing its base 2 and reinforcing plate 4 to a plate, leather, cloth, etc. using fixing means such as rivets.

A coating layer of molybdenum disulfide lubricant (H Group HTP-2 manufactured by Sumitomo Metal Mining Co., Ltd.) is formed on the surface of the contact plate 6 of the pedestal 2 on the sliding portion 6a with the shaft 12.

In order to hold an object using the clamping tool 1, the holding tool 3, which is open with respect to the base 2, may be rotated so as to clamp the object and overlap it with the base 2. The shaft portion 12 of the holding tool 3 is formed into a plate shape with a width larger than its thickness, and when the holding tool is in an open state, it extends along the contact plate portion 6 within the support portions 7 and 8. However, when the presser 3 is rotated in the closing direction from this state, the width of the shaft portion 12 deforms the support portions 7, 8 and the contact plate portion 6 so that they are pushed apart from each other. Since it can be used, pedestal 2
Due to the elasticity of the material, the presser 3 receives a strong reaction force in the closing direction. Therefore, the article is firmly held between the presser 3 and the pedestal 2.

This clamping tool 1 is integrally provided with a reinforcing plate 4 for backing up the contact plate part 6 on the back side of the pedestal 2, so that strong clamping pressure can be obtained. Also, presser tool 3
A rubber coating is applied to the surface of the pedestal 2, and a protrusion 20 is provided near the free end of the side facing the pedestal 2 so as to protrude so as to intersect with the plate surface of the pedestal 2 or its extended surface when nothing is interposed therebetween. presser foot 3.
An object such as a belt held between the presser holder 3 and the pedestal 2 is effectively prevented from deviating from the free end side of the presser 3. In this case, the plate portion of the presser 3 has a protrusion 20
The pedestal 2 is brought into contact with the plate surface of the pedestal 2 or the surface of the sheet material to which it is attached.
is supported almost parallel to the In particular, the presser 3 is formed longer than the pedestal 2, and as shown by the chain line in FIG.
If it is configured to fit into the side, it is extremely difficult for the object held between the presser 3 and the base 2 to come off.

In addition, in this clamping tool 1, the shaft portion 12 of the holding tool 3
The edge of is formed in a straight line as mentioned above,
Since a lubricant layer is formed on the surface of the contact plate 6 on which the shaft portion slides, rattling and squeaking are effectively prevented during rotation during opening and closing. Further, since the reinforcing plate 4 is provided with a stepped portion 4a, which is raised near the free end of the abutment plate portion 6, the shaft portion 12 is effectively prevented from coming off the support portions 7, 8.

Next, FIG. 5 shows an example in which this clamp holder 1 is attached to a pocket bell case 30 made of leather. This case 30 can be held by the clamp holder 1 with a pager 31 for calling stored therein.
As shown in FIG. 6, it is attached to the belt 33 of pants. In this example, the base 2 and the reinforcing plate 4 are fixed to the inside of the outer skin 30a of the case 30, and the presser 3
A joint between the case 30 and the pedestal 2 is exposed to the outside through a slit 37 provided on the back surface of the case 30. In this way, since the reinforcing plate 4 extending above and below the joint portion of the pedestal 2 is integrally provided, the end of the pedestal 2 does not protrude outward from the slit 37 of the outer skin 30a. Further, since the protrusion 20 at the tip of the presser 3 is pressed so as to bite into the outer cover 30a, a space 40 closed by the outer cover 30a and the presser 3 is formed, and the belt 33 passed through this space 40 is has become extremely difficult to deviate from. In the figure, 41 is a lid that can be opened and closed, and 42 is a lid 41.
This is a Velcro tape for chucks that holds it in the closed position.

FIG. 7 shows an embodiment different from the above-mentioned clamping tool 1', in which the tip of the plate part 3a of the holding tool 3 protrudes from the coating layer 15, and this part is curved to form a protrusion 20''. Also, pedestal 2
includes a receiving part 2 that elastically engages with the projection 20''.
0a is provided. Note that the protruding stripes 15a' of the coating layer 15 are formed to have a width of about 3 mm and a height of about 3 mm, making the anti-slip effect even greater. The pedestal 2 is fixed to a reinforcing plate 4 in which reinforcing rib-like vertical grooves 4a are formed, and has excellent strength.

In the clamping tool 1', the protrusion 20'' and the receiving part 20a are elastically engaged in the closed state, so the clamping force is extremely strong, and it will not fall off from the clamped object such as a belt during use. To remove it, just pull it in the opening direction with your fingers.

FIGS. 8 and 9 show a further different embodiment, in which the protrusion of this clamping tool 1'' is formed into a plate shape, and a magic tape (cross check) 42 as shown in FIG. 5 is attached to the surface of the protrusion. One side (male side) is attached. That is, a shallow rectangular recess 50 is formed on the surface of the protrusion 45, and a base fabric portion of Velcro tape is adhered to the recess 50. 45 comes into contact, for example, the pager case 3 in FIG.
0 has the other side (female side) of the magic tape 42 attached. In this way, the protrusion 45 of the clamping tool
If a Velcro tape is attached to the surface of the holder and the part where the protrusion contacts in the closed state, the holder can be held more securely. Note that a groove 52 having an arcuate cross section is formed inside the projection 45 in the illustrated example.

In addition, instead of magic tape like this,
A plastic magnet (so-called plastic magnet) may be provided at the portion where the presser 3 and the presser 3 contact each other in the closed state, and the holding force may be used to ensure the clamping.

FIG. 10 shows an example in which a plurality of pairs (two pairs in the illustrated example) of pedestal 2 and presser plate 3 are attached to one reinforcing plate 4', and the stepped portion 4a is common. If a plurality of sets of pedestals and presser plates are provided on one reinforcing plate 4' in this way, it becomes convenient for holding wide items.

[Effects of the invention] As is clear from the above explanation, the clamping tool according to the present invention has a thin thickness, a high clamping force, a joint between the presser part and the base that is difficult to separate, and is also strong. It has become highly practical.
