Description

The present invention is a pressing tool used for attaching a fitting such as a decorative panel or an interior panel that is fitted only by fitting such as hooking a locking portion into a groove without using a screw or bolt. It is about.

  Interior panels and decorative panels in the interior of various vehicles such as railway vehicles, cars, airplanes, etc., or to hide the internal structure from passengers of the vehicle or those who use the building Etc. are attached. In particular, special trains such as express trains are designed so that screws, bolts, etc. are not as conspicuous as possible so that passengers can have a comfortable stay or have a clean, luxurious interior. ing. As one of them, as shown in FIG. 16, a screw concealment (fitting) 51 for concealing the head of the screw 50 is attached in place.

In general, a screw that is fixed to a position that can be visually recognized by a human being may be a flat head screw that prevents it from popping out and standing, and may be fixed to the plate on the structure side. The part of the groove was visible and was not good looking. Therefore, the above-described screw concealment 51 is used to conceal the head portion of the screw.
The screw concealment 51 is formed of a hard plastic, for example, in a belt shape (belt shape), and two claw portions (locking portions) 51a are formed on both sides along the longitudinal direction. . Then, by pushing the two claw portions 51a into the two long grooves 52a formed in the plate 52, the claw portions 51a are deformed by their own elasticity in the grooves 52a and are hooked and fitted. . As a result, the screw concealment 51 is attached to the plate 52 by fitting and fixing. By attaching the screw concealment 51, even the head portion of the screw 50 can be surely concealed from human eyes.
In addition, since the back surface 51b of the screw concealment 51 contacts the pressing surface 52b of the plate 52 at the time of fitting and fixing, the posture after attachment is in a stable state.

  In particular, the screw concealment 51 is frequently used everywhere since it is easy to use because it is simply fixed by simply pushing the claw portion 51a into the groove 52a. By the way, the screw concealment 51 is attached at the final stage of the restoration work after, for example, maintenance of the railway vehicle, and has been attached by a skilled worker. This is because, as described above, the screw concealment 51 is made of hard plastic and has a certain degree of hardness (elastic force), so that it is difficult to push the two claw portions 51a into the groove 52a. This is because of the need for knowledge and experience. Moreover, since the screw concealment 51 used in the interior of a railway vehicle or the like is formed in a long strip shape, it is also difficult to handle.

From these points, a skilled worker attaches, but even a skilled worker cannot easily push the claw portion 51a into the groove 52a and fix it. For example, a bamboo spatula or the like The current situation is that you are pushing in by using both hands while using.
Since the conventional method of attaching the screw concealment 51 is merely performed by a skilled worker using a bamboo spatula or the like as described above, publicly known documents describing such methods are currently available. Has not been found and cannot be disclosed.

However, the conventional method for attaching the screw concealment 51 has the following problems.
That is, since a skilled worker attached using a bamboo spatula or the like, a difference was made in the finish according to the skill of the worker, and the appearance was uneven.
In addition, when the claw portion 51a is pushed into the groove 52a and pushed into the groove 52a, the bamboo bevel slips by mistake, and there is a risk that the screw concealment 51 will be cracked, scratched or deformed. It was. On the other hand, if the work is performed carefully, it takes time for the mounting work and the work efficiency is poor.
Furthermore, when using a bamboo spatula or the like, sliding the bamboo spatula against the claw part 51a and pushing the claw part 51a, the screw concealment 51 is somewhat stretched. Therefore, it is necessary to calculate the length of extension in advance and adjust the length of the screw concealment 51, which is not easy for anyone to do, but requires experience.

  The present invention has been made in view of the above-described problems of the prior art, and the object thereof is to hardly attach scratches and the like, and it is possible to efficiently attach a fitting such as a screw concealment to an attachment object in a short time. At the same time, it is an object of the present invention to provide a pushing tool that can be mounted with a uniform finish regardless of the skill of the operator.

In order to achieve the above object, the present invention provides the following means.
The invention according to claim 1 is an indentation tool for use in attaching a belt-like fitting object in which a locking portion is pushed into a groove formed in an attachment object and is fitted and fixed by its own elastic force. A gripping portion extending in one direction with a constant thickness, and an arm portion having a pair of protrusions connected to at least one end of the gripping portion and arranged to face each other with the tips spaced apart from each other. , Arranged in a state of being sandwiched between the pair of protrusions, and fixed to each of the pair of protrusions so as to be rotatable about a rotation axis orthogonal to the protrusion direction, and the outer edge portion is outward of the protrusions. A pressing roller tool that is formed so that the outer edge side is thinner than the rotation center side and the outer edge is a curved surface. To do.

In the pushing tool according to the present invention, the operator grasps the gripping part with one hand and presses the roller part rotatably fixed to the pair of projecting parts at the tip of the arm part against the locking part. A stop part can be pushed in in a groove | channel and it can fit together, and a strip | belt-shaped fitting thing can be easily attached to an attachment target object.
For example, in the case of attaching a screw concealment that is formed in a band shape (belt shape) and has two claw portions (locking portions) to a plate that is an attachment object in which two long grooves are formed. This will be described in detail. First, the operator pushes the entire one of the concealed claw portions into the one groove of the plate by hand as in the prior art. Next, the screw concealment is held so that the other claw portion is positioned in the opening of the other groove of the plate. In this state, the operator grasps and grasps the grip portion, presses the roller portion fixed to the tip of the arm portion against the other claw portion, and pushes it into the groove.
Thereby, the nail | claw part of the part which is contacting the roller part is pushed in in a groove | channel with this roller part, and it deform | transforms and catches in a groove | channel by own elasticity. At this time, since the outer edge side of the roller part is formed thinner than the rotation center side, the nail part is not compressed when the nail part is pushed into the groove, and the pushing operation is affected. There is no.

Next, the operator moves the grip portion along the other groove while pushing the roller portion. Thereby, a roller part rotates around a rotating shaft and pushes the nail | claw part which has not been pushed in into a groove | channel one after another. The claw portions pushed in one after another are deformed in the grooves by their own elasticity like the claw portions pushed in first, and are successively hooked and fitted together.
As a result, the entire other claw portion can be pushed all the way into the other groove, and the screw concealment can be fitted to the plate and fixed by fixing.

In particular, since the roller portion is circular, the claw portion can be reliably pushed in without rotating and smoothly rotating, and uneven fitting can be eliminated. Further, since the roller portion is circular and is formed so that the outer edge is a curved surface, it is difficult to damage the screw concealment during pushing and rotation. Furthermore, since the roller part once pushed in is rotated, even if a force is applied, the roller part is difficult to slip. For this reason as well, it is difficult to damage the screw concealment.
In addition, the claw can be easily and reliably pushed into the groove by simply moving the grip portion along the groove, so that, unlike using a conventional bamboo spatula, regardless of the skill of the operator. Screw concealment can be attached with a uniform finish.
Furthermore, since the roller portion rotates, unlike the case where a conventional bamboo spatula is used, there is no elongation in the screw concealment. Therefore, since it is not necessary to adjust the length according to the elongation in advance, the experience is unnecessary and the attachment becomes easier.

As described above, according to the pressing tool of the present invention, the circular roller portion is moved along the groove while being pressed against the locking portion, so that it is difficult to be damaged and the screw is efficiently fitted in a short time. An object can be attached to an attachment object, and attachment can be performed with a uniform finish regardless of the skill of the operator.

Hereinafter, 1st Embodiment of the pushing tool which concerns on this invention is described with reference to FIGS.
As shown in FIGS. 1 and 2, the pushing tool 1 of the present embodiment has two claw portions (locking portions) in two long grooves 2 a formed on a plate 2 that is an attachment object. The belt-shaped screw concealment (fitting object) 3 which is inserted and fixed by its own elastic force when 3a is pushed in is used when attaching.
In the present embodiment, a case where the screw concealment 3 is attached to the plate 2 fixed inside the railway vehicle will be described as an example.
In this plate 2, two long grooves 2a are formed parallel to the longitudinal direction with a space therebetween, and a flat pressing surface 2b is formed between the two grooves 2a. In addition, screw holes that are countersunk at regular intervals are formed in the pressing surface 2b. And the plate 2 is being fixed indoors by attaching the countersunk | screw 4 to this screw hole.

  The screw concealment 3 is formed of a hard plastic in the shape of a band, and has two claw portions 3a that fit into the two grooves 2a. At this time, when the two claws 3a are respectively pushed into the grooves 2a, the two claws 3a are deformed so as to be opened outward by their own elastic force, and are hooked and fixed to the grooves 2a. Yes. At this time, the screw concealment 3 is stabilized in posture by the back surface 3b coming into contact with the pressing surface 2b and more reliably catches the claw portion 3a.

  As shown in FIGS. 3 and 4, the pushing tool 1 is connected to a grip portion 10 extending in one direction with a constant thickness T, and is connected to at least one end side of the grip portion 10, and the tips are spaced apart from each other. It is arranged in a state sandwiched between a pair of protrusions 11, 12 and an arm part 13 having a pair of protrusions 11, 12 opposed to each other in a state, A circular roller portion 14 that is fixed to be rotatable around a rotation axis X orthogonal to the protruding direction and whose outer edge portion is exposed to the outside of the protruding portions 11 and 12 is provided.

The grip portion 10 is made of aluminum, which is a metal material. For example, the grip portion 10 is formed in a rod shape with rounded corners having a thickness T of 15 mm and a width H of about 25 mm. Also. The grip portion 10 is provided with a grip 15 whose surface is partially coated with a resinous material.
In the present embodiment, the arm portion 13 is configured integrally with the grip portion 10 and is formed to extend along the axial direction L of the grip portion 10 from one end side. In other words, the grip portion 10 and the arm portion 13 are both made of aluminum and have a rod shape extending in the axial direction L. The arm portion 13 is formed to be narrower than the grip portion 10 and to be thinner as it goes to the tip.

Further, as shown in FIGS. 3 and 5, the tip of the arm portion 13 is bifurcated with an interval of about 5 mm. ing. A bearing 16 such as a micro bearing that rotatably supports a shaft (rotary shaft member) 18 to be described later is provided on the opposing surfaces of the pair of protrusions 11 and 12. That is, the line connecting the centers of the bearings 16 is the rotational axis X. The pair of protrusions 11 and 12 are formed with insertion holes 11a and 12a through which the shaft 18 can be inserted along the rotation axis X.
The bearing 16 is attached in a state of being inserted into the pair of protrusions 11 and 12 from the outside of the pair of protrusions 11 and 12.

  The roller part 14 is made of stainless steel, which is a metal material. For example, the roller part 14 is formed to have a diameter of 20 mm (within a range of 15 mm to 25 mm) and a central axis side thickness of 3 mm (within a range of 1 mm to 5 mm). Has been. Moreover, the roller part 14 is formed so that the thickness of an outer edge side may become thinner than the rotation center side. Specifically, as shown in FIG. 5, it is formed so that the thickness gradually decreases toward the outer edge, that is, has a tapered cross section. Further, the outer edge of the roller portion 14 is formed to be a curved surface with R so as not to be sharpened.

Further, an insertion hole 14 a is formed at the center of the roller portion 14 through which the shaft 18 disposed along the rotation axis X is inserted. The shaft 18 is a round bar formed of stainless steel, for example, with a diameter of 4 mm, and is formed so that the length is longer than the width of the pair of projecting portions 11 and 12. That is, the shaft 18 has the roller portion 14 sandwiched between the pair of protruding portions 11 and 12, and the insertion hole 11 a of the one protruding portion 11, the insertion hole 14 a of the roller portion 14, and the insertion of the other protruding portion 12. The pair of protrusions 11 and 12 can be inserted through the hole 12a.
At this time, the shaft 18 is inserted into the bearing 16 provided in each of the pair of projecting portions 11 and 12 and the insertion hole 14a of the roller portion 14 in a press-fitted state. As a result, the roller portion 14 rotates about the rotation axis X together with the shaft 18 and is supported by the bearing 16 via the shaft 18.

  Further, on both sides of the roller portion 14, contact portions 14b that are in surface contact with the inner ring portion of the bearing 16 are formed so as to surround the opening of the insertion hole 14a. By this contact part 14b, the roller part 14 rotates smoothly around the rotation axis X in a state where lateral blur is suppressed.

  Further, a reduced diameter portion 18a having a small diameter is formed at both ends of the shaft 18, and an E ring 19 made of stainless steel is detachably attached to the reduced diameter portion 18a. The E-ring 19 is formed with a larger diameter than the insertion holes 11a and 12a of the pair of protrusions 11 and 12. The E-ring 19 restricts the movement of the shaft 18 in the direction of the rotation axis X so that it does not fall out of the pair of protrusions 11 and 12. Conversely, the roller portion 14 can be removed by removing the E-ring 19 and pulling the shaft 18 from the pair of projecting portions 11 and 12. That is, the roller unit 14 is configured to be detachable.

The case where the screw concealment 3 is attached to the plate 2 attached to the inside of the railway vehicle and the head portion of the screw 4 fixed to the plate 2 is concealed by the pushing tool 1 configured as described above will be described.
First, as shown in FIG. 6, the operator pushes the entire one claw portion 3 a of the screw concealment 3 into the one groove 2 a of the plate 2 by hand as in the conventional case. Next, the screw concealment 3 is held in a slightly rounded state so that the other claw portion 3 a is positioned at the opening of the other groove 2 a of the plate 2. In this state, the operator grasps and grasps the grip portion 10 and presses the roller portion 14 fixed to the tip of the arm portion 13 against the other claw portion 3a as shown in FIG. Push into.
In addition, it is preferable to push in the nail | claw part 3a as close as possible to the edge part of the screw concealment 3 at this time.

  Thereby, the claw part 3a in contact with the roller part 14 is pushed into the groove 2a together with the roller part 14, and is deformed and caught in the groove 2a by its own elasticity. At this time, since the outer edge side of the roller portion 14 is formed thinner than the rotation center side, the pressure on the claw portion 3a can be suppressed as much as possible when the claw portion 3a is pushed into the groove 2a. .

Next, the operator moves the grip portion 10 along the other groove 2a while pressing the roller portion 14. Thereby, the roller part 14 rotates around the rotation axis X, and pushes the claw part 3a that is not yet pushed into the groove 2a one after another. The claw part 3a pushed in one after another is deformed in the groove 2a by its own elasticity like the claw part 3a pushed in first, and is hooked and fitted one after another. As a result, the entire other claw portion 3a can be pushed all the way into the other groove 2a, and the screw concealment 3 can be fitted to the plate 2 and fixed thereto.
In addition, since the back surface 3b contacts the pressing surface 2b of the plate 2, the screw concealment 3 is securely fitted and fixed by its own elastic force without being out of position.

  In particular, since the roller portion 14 is circular, the claw portions 3a can be pushed in one after another by smoothly rotating (without leaving an interval), and uneven fitting can be eliminated. Moreover, since the roller part 14 is circular and formed so that the outer edge is a curved surface, it is difficult to damage the screw concealment 3 during pushing and rotation. Furthermore, since the roller part 14 once pushed in is rotated, the outer edge part of the roller part 14 moves in a state guided by the groove 2a. Therefore, even if force is applied, the roller part 14 is difficult to slip. This also makes it difficult to damage the screw concealment 3.

Further, by simply moving the grip portion 10 along the groove 2a, the entire claw portion 3a can be easily and surely pushed into the groove 2a to attach the band-shaped screw concealer 3. Unlike the case of using, the screw concealment 3 can be attached with a uniform finish regardless of the skill of the operator.
Further, since the screw concealment 3 is pushed in by the rotation of the roller portion 14, the screw concealment 3 does not stretch unlike the case of using a conventional bamboo spatula. Therefore, it is not necessary to calculate the elongation in advance and adjust the length of the screw concealment 3. For this reason, no experience is required, and anyone can easily attach the screw concealment 3.

Moreover, since the roller part 14 is supported by the bearing 16 via the shaft 18, rotation is smooth and it is hard to damage the screw concealment 3 etc. In addition, since the rotation of the roller portion 14 is smooth, the grip portion 10 can be easily moved, and the working efficiency can be further improved.
In particular, since the roller portion 14 is gradually thinned so as to have a tapered cross-section toward the outer edge, the outer surface of the roller portion 14 is a smooth surface having no steps. Therefore, when the roller part 14 is pushed in or rotated, the screw concealment 3 and the plate 2 can be prevented from being caught as much as possible, and the reliability of the work is improved.

Furthermore, since the roller part 14 is formed in 20 mm whose diameter is in the range of 15 mm to 25 mm, the stability at the time of rotation is excellent and even if there is a wall surface in the vicinity of the plate 2, Installation can be performed with minimal influence from the wall surface.
For example, when the diameter of the roller portion 14 is larger than the above range, the distance between the center of the rotation axis X and the outer edge becomes large, so that when the force is applied, the roller portion 14 is easily displaced and lacks stability. Moreover, when the plate 2 exists in the wall surface vicinity, when the roller part 14 contacts a wall surface, it will become impossible to press the screw concealment 3 of the wall surface vicinity into the groove | channel 2a. Therefore, such a problem can be eliminated as much as possible by keeping the diameter of the roller portion 14 within the above range.
On the other hand, when the diameter is made smaller than the above range, the strength is reduced and the exposed portion of the roller portion 14 is reduced. For example, the pair of projecting portions 11 and 12 themselves are in contact with the screw cover 3 or the like. Although it may occur, such a problem can be eliminated as much as possible by keeping it within the above range.

  Moreover, since the roller part 14 is formed in 3 mm whose thickness of the rotation center side is in the range of 1 mm to 5 mm, it is possible to maintain a certain strength and to eliminate pressure on the screw concealment 3 as much as possible. . For example, when the thickness is larger than the above range, the taper becomes tight, and the roller portion 14 is likely to come into contact with the screw concealment 3 and the like when the roller portion 14 is pushed in and rotated, thereby increasing the pressure. As a result, the screw concealment 3 is easily damaged. Further, when the thickness is made smaller than the above range, the strength is lowered and the outer edge becomes sharper, so that it becomes easy to scratch. Therefore, by setting the thickness within the above range, such a problem can be eliminated as much as possible.

  In addition, since the grip portion 10, the arm portion 13, the roller portion 14, and the shaft 18 are formed of a metal material such as aluminum or stainless steel, even if a force is applied with high rigidity, there is no backlash and the stability is maintained. Is done. Therefore, it is easy to attach the screw concealment 3.

  Further, since the grip portion 10 is provided with a grip 15 coated with a resinous material, the grip portion 10 is easy to grip, is not easily fatigued, and is not easily slipped. In addition, for example, by using a thermosetting resin for the grip 15, it is possible to provide insulation and flame retardancy, and it is possible to improve electric shock prevention and safety. That is, even if the work is performed in a place close to an environment where sparks are scattered, such as welding work and grinder work, it is safe. Further, by using fluorine resin, silicon resin, or the like for the grip 15, antifouling and antistatic can be achieved. Thus, by using various resinous materials for the grip 15, it is possible to have a function according to the purpose and to further increase the added value.

  Moreover, since the roller part 14 is a structure which can be attached or detached, even if it uses for a long period and wears out, it can be replaced | exchanged for a new thing. Therefore, it is easy to use and excellent in convenience.

  As described above, according to the pushing tool 1 of the present embodiment, the circular roller portion 14 is moved along the groove 2a while being pressed against the claw portion 3a. The cover 3 can be attached to the plate 2 and can be attached with a uniform finish regardless of the skill of the operator. As a result, it is possible to reduce the maintenance cost associated with the attachment / detachment of the screw concealment 3.

  In the first embodiment, the roller portion 14 is formed so that the thickness gradually decreases toward the outer edge. However, the present invention is not limited to this, and for example, the roller portion 14 is formed so as to be thin in a step shape. It doesn't matter.
