Abstract

<P>PROBLEM TO BE SOLVED: To provide a molding capable of being restuck without making any separation mark when the molding is mounted by sticking. <P>SOLUTION: A sticky gel 7 is attached to a mounting face 21 of a clamp 1, a surface 71 of the gel 7 is coated with a synthetic resin sheet 8, and the synthetic resin sheet 8 is provided with an opening portion 81 for exposing the gel 7. As the surface of the gel 7 is coated with the synthetic resin sheet 8, it is prevented from being stuck without reason, or the attachment of dust can be prevented. When the force is applied to the mounting face 21 so that it is pressed to a mounted side in a state of keeping the synthetic resin sheet 8, the gel 7 is extruded from the opening portion 81 and stuck to the other side, thus the clamp 1 can be temporarily fixed. Then the synthetic resin sheet 8 is stripped off to expose the surface 71 of the gel 7, and the gel 7 is stuck to the other side, so that the clamp1 can be mounted. As the clamp 1 can be separated even after mounting, it can be stuck again. Further the separation mark is not left. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention belongs to the technical field of synthetic resins or metal molded products.

  For example, there are synthetic resin or metal molded products that are used by attaching to a wall surface, a sheet metal, a casing of an electronic device, or the like. As an example, there is a clamp described in Japanese Utility Model Laid-Open No. 57-104081 (Patent Document 1). In addition, there are spacers interposed between the casing of the electronic device and the printed circuit board.

These are common in that they have attachment bases for attachment to other objects such as wall surfaces, although the functional parts for performing functions as clamps, spacers, and the like are different from each other.
Japanese Utility Model Publication No. 57-104081 (FIG. 3)

In order to attach a molded product shown as a conventional example to a wall surface, for example, there is a fixing method such as screwing, but a double-sided adhesive tape is often used.
However, double-sided pressure-sensitive adhesive tapes have drawbacks that it is difficult to reapply and that marks remain when peeled off.

The molded product according to claim 1 is:
A synthetic resin or metal molded article comprising an attachment base having an attachment surface for attachment to another object, and a functional part connected to the attachment base;
An adhesive gel is attached to the mounting surface,
The surface of the gel opposite to the mounting surface is coated with a thin material,
The thin material is provided with an opening for exposing the gel.

The molded product of claim 1 is provided with an attachment base, and the attachment base is provided with an attachment surface. The mounting surface may be a curved surface, but a flat surface is more versatile.
An adhesive gel is attached to the mounting surface.

  A gel is a polymer material having a three-dimensional network structure in which a large number of polymers are partially connected to each other by bonding of specific parts on the chain. It is preferable that a softening agent (for example, an oil component) is included in the gap between the network structures of the base polymer to have lost fluidity.

  Examples of the base polymer include various thermoplastic elastomers such as styrene, olefin, ester, amide, and urethane, and hydrogenated or other modified products thereof, or styrene, ABS, and olefin. Type, vinyl chloride type, acrylic type, carbonate type, acetal type, nylon type, halogenated olefin type (tetrafluoroethylene type, fluorinated ethylene chloride type, fluorinated ethylene propylene type, etc.), cellulose type (ethylcellulose type, etc.) ), And rubber modified products of these resins. In addition, these various thermoplastic resins may be used independently, or 2 or more types may be blended and used.

  Examples of the softener include various rubber or resin softeners such as mineral oil, vegetable oil, and synthetic. Examples of mineral oils include paraffinic, naphthenic, and aromatic process oils, and vegetable oils include castor oil, cottonseed oil, linseed oil, rapeseed oil, soybean oil, palm oil, coconut oil, peanut oil, wood wax, Examples include pine oil and olive oil. These softeners may be used alone or in combination of two or more having good compatibility with each other. In addition, since the hardness of a gel becomes so low that there is much addition amount of a softening agent, what is necessary is just to prepare so that it may become desired hardness.

  Moreover, tackiness can be imparted or adjusted by using various tackifiers (tackifier) such as coumarone resin, coumarone-indene resin, phenol resin, terpene resin, petroleum resin, rosin resin and the like.

  Furthermore, in addition to the base polymer, softener, and seed tackifier, additives such as known resin components can be used in combination for improving various properties. As the resin component, for example, a polyolefin resin or a polystyrene resin can be used in combination. By adding these, workability and heat resistance can be improved. Examples of the polyolefin resin include polyethylene, isotactic polypropylene, and a copolymer of propylene and a small amount of other α-olefin (for example, propylene-ethylene copolymer, propylene / 4-methyl-1-pentene copolymer). ), Poly (4-methyl-1-pentene), polybutene-1, and the like.

As other additives, antibacterial agents, hindered amine light stabilizers, ultraviolet absorbers, antioxidants, inorganic fillers, and colorants can be added as necessary.
There is no limitation on the method of attaching the gel to the mounting surface, but outsert is simple.

  The gel may be attached to the entire surface of the mounting surface, or may be attached to a part or a part thereof. There is no particular limitation on the adhesion thickness of the gel, but if it is too thin, it will be difficult to compensate for surface irregularities of the other side to be adhered by deformation of the gel, and even if it is too thick, only the amount used will be excessive, There is naturally a suitable range.

  Since the gel is sticky, if it is left exposed, it will stick unnecessarily at the time of storage, etc. or dust will adhere. However, since the surface opposite to the gel mounting surface is covered with a thin material, such a problem is prevented.

The material of the thin material is not particularly limited, and for example, a plastic film, a plastic sheet, a release paper, or the like can be used.
The thin material is provided with an opening for exposing the gel. The opening is provided as a hole or notch, but the shape is not limited. However, when the opening area becomes large, there is a risk of sticking unnecessarily, or dust or the like may adhere to it. The number of openings is not limited, but if the number increases depending on the specification, the total opening area increases, so that the temporary fixing force can be improved.

  Since the thin material is provided with an opening that exposes the gel, if a force is applied to the mounting surface against the mounting partner while the thin material is applied, the gel is generated by the pressure generated between the mounting surface and the counterpart. Is pushed out of the opening and sticks to the other party. And even if this force is released, the gel remains adhered to the other party, so that the molded product is temporarily fixed to the other party. This temporary fixing can be easily released, and there is no trace left on the other party. Moreover, it can also be temporarily fixed temporarily.

  After determining the mounting position of the molded product by temporary fixing, or omitting temporary fixing, the thin material is peeled off to expose the surface of the gel, and the gel can be adhered to the other party. The molded product can be attached. At this time, if a force is applied so as to press the mounting surface against the mounting counterpart, adhesion by the gel becomes more reliable.

Even after mounting in this manner, the molded product can be peeled off, so that it can be re-applied. Moreover, there are no traces removed.
The functional unit varies depending on the application of the molded product. To name a few, a functional unit for gripping a long object (Japanese Patent No. 1615563, Japanese Patent Laid-Open No. 11-351451, Design Registration No. 978223) No.), a support function part (design registration No. 701407) for supporting a plate material such as a printed circuit board at a distance from the chassis, a protection function part (design registration No. 978223) for protecting the edge portion, and the like.

  The opening may be a hole or a notch as described in claim 2. As for the shape, a circular shape, a rectangular shape, a triangular shape, a polygonal shape, a star shape, and an elliptical shape are exemplified in the case of forming a hole.

  The dimensional relationship between the gel and the mounting surface is such that the projected size of the gel onto the mounting surface is equal to or smaller than the mounting surface, that is, the gel is on the side of the mounting surface. It is better to have a configuration that does not protrude.

If the projected dimension of the gel onto the mounting surface is made equal to the mounting surface, the above-described temporary fixing can be performed using the side surface of the gel.
If the projected dimension of the gel on the mounting surface is made smaller than that of the mounting surface, the side surface of the gel can be prevented from sticking to other objects during storage or operation.

  The dimensional relationship between the gel and the thin material is such that the projected dimension of the gel onto the thin material is smaller than that of the thin material, that is, the gel does not protrude from the thin material. Then, it is possible to prevent the side surface of the gel from sticking to other objects during storage or operation.

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example]
In this embodiment, the molded product of the present invention is embodied as a clamp.

  As shown in FIG. 1, the clamp 1 includes a plate-shaped mounting base 2, a band portion 3 connected to the plate-shaped mounting base 2, a locking elastic portion 4 connected to the tip of the band portion 3, and a locking connected to the mounting base 2. A main body 6 having a portion 5 and the like, a gel 7 attached to the attachment surface 21 of the attachment base 2, and a synthetic resin sheet 8 (corresponding to a thin material) covering a surface 71 opposite to the attachment surface 21 of the gel; Consists of.

  The main body 6 is a synthetic resin (polypropylene resin in this embodiment, but synthetic resin such as nylon, polyethylene, POM, polycarbonate, acrylic, PBT, PET, etc., TPE (olefin, styrene, polyamide, polyester, nitrile). Elastomers such as chlorinated polyethylene, SEBS, etc.) can also be used.

The belt part 3 is formed in a C shape as a whole. The four node portions 31 are thinner than the other portions, and are easily bent and stretched at the node portions 31.
The locking elastic portion 4 is substantially U-shaped, and one end of the U-shape is connected to the tip of the band portion 3.
A knob piece 41 extends outwardly from the other end, and a movable side locking projection 42 is provided between the knob piece 41 and the U-shaped bottom. An auxiliary piece 32 extends from the band 3 in parallel with the knob piece 41.

The locking portion 5 has a box shape with an accommodation hole 51 provided inside, and a fixed-side locking projection 52 is provided on the inner periphery thereof.
The locking portion 5 is provided to lock the locking elastic portion 4. When the locking elastic portion 4 is inserted into the receiving hole 51, the locking elastic portion 4 is elastically deformed by the movable side locking projection 42 coming into contact with the fixed side locking projection 52, and the movable side locking projection 42 is fixed on the fixed side. When it passes through the locking projection 52, it is elastically repelled and the movable side locking projection 42 is locked to the fixed side locking projection 52.

  As described above, when the locking elastic portion 4 is locked to the locking portion 5, an annular body is formed by the band portion 3, the locking portion 5 and the attachment base portion 2. With this annular body, a long object such as a tube or a cable can be gripped.

The gel 7 is plate-shaped, but as shown in an enlarged view in FIG. 2B, a circular recess 72 is formed at the center thereof.
The synthetic resin sheet 8 is provided with an opening 81 having a diameter larger than that of the recess 72, and the recess 72 and its periphery are exposed to the opening 81.

The procedure for attaching the gel 7 to the mounting surface 21 is as follows.
First, as shown in FIG. 3, the cavity 6 is defined by the mounting surface 21 of the mounting base 2 and the inner peripheral surface 73 of the mold by holding the body 6 of the clamp 1 on one side (for example, the movable side) of the mold. C is formed, and the synthetic resin sheet 8 is placed on the mating surface 74 of the mold so that the opening 81 communicates with the cavity C.

  Then, by closing the mold, the other side (for example, the fixed side) of the mold is brought into close contact with the synthetic resin sheet 8, and the synthetic resin sheet 8 is sandwiched between the movable side and the fixed side. As a result, the cavity C is hermetically sealed, and the gel 7 is discharged from the nozzle that has entered the cavity C through the opening 81 to fill the cavity C with the gel 7. The gel 7 filled in the cavity C adheres to the mounting surface 21 due to its adhesive force. The gel 7 discharged from the nozzle is heated to an appropriate temperature in order to improve fluidity. After waiting for a time for the gel 7 to cool, it is opened and the clamp 1 is removed.

  In the clamp 1, the adhesive gel 7 is attached to the mounting surface 21, the surface 71 of the gel 7 is covered with the synthetic resin sheet 8, and the synthetic resin sheet 8 is provided with an opening 81 that exposes the gel 7. ing.

  Since the gel 7 is sticky, if it is left exposed, it will stick unnecessarily during storage or dust will adhere. However, since the surface of the gel 7 is covered with the synthetic resin sheet 8, such a problem is prevented.

  Moreover, since the synthetic resin sheet 8 is provided with the opening 81 that exposes the gel 7, a force is applied to press the mounting surface 21 against the mounting counterpart (for example, a sheet metal or a housing) while the synthetic resin sheet 8 is attached. Is applied, the gel 7 is pushed out from the opening 81 by the pressure generated between the mounting surface 21 and the counterpart and adheres to the counterpart. And even if this force is released, the gel 7 remains adhered to the other party, so the clamp 1 is temporarily fixed to the other party. This temporary fixing can be easily released, and there is no trace left on the other party. Moreover, it can also be temporarily fixed temporarily.

  After determining the mounting position of the clamp 1 by temporary fixing, or omitting the temporary fixing, the synthetic resin sheet 8 is peeled off to expose the surface 71 of the gel 7 and the gel 7 is adhered to the other side to clamp 1 Can be attached. At this time, if a force is applied to press the mounting surface 21 against the mounting partner, the adhesion by the gel 7 becomes more reliable.

Even after mounting in this manner, the clamp 1 can be peeled off, so that it can be re-attached. Moreover, there are no traces removed.
In the present embodiment, a clamp having a gripping function unit for gripping a long object is illustrated. However, the function part is, for example, a gripping function part for gripping a long object (Japanese Patent No. 1615563, Japanese Patent Laid-Open No. 11-351451). Design registration No. 978223), support function part (design registration No. 701407) for supporting a plate material such as a printed circuit board with a distance from the chassis, protection function part (design registration No. 978223) for protecting the edge portion, etc. Yes, but there are no particular limitations.

Further, in this embodiment, a synthetic resin molded product is illustrated, but for example, a metal molded product such as a piping stopper described in Japanese Utility Model Publication No. 59-8049, described in Design Registration No. 387105. The present invention is also applicable to molded products such as electric wire supports, electric wire fasteners described in Design Registration No. 638279, and the like.
[Various examples of openings]
The position of the opening can be provided, for example, at the center of the thin material or other than the center. Although a plurality of openings can be provided, it is desirable to arrange them so as to improve the overall balance. When three or more openings are provided, the balance is good if they are arranged at equal intervals.

  When making an opening into a notch, the structure by which an opening is provided in the at least 1 edge part of a thin material is preferable. In that case, the balance is good when the opening portion which is a notch is provided at substantially the center of the opposite edge portions of the thin material.

An example of the shape and arrangement of such openings is shown in FIG.
As shown in FIG. 4A, a circular opening 81 is provided at the center of the synthetic resin sheet 8, or the opening 81 is point-symmetric or line-symmetric as shown in FIGS. 4B and 4C. Or three or more openings 81 can be arranged at equal intervals as shown in FIG.
