Description

The present invention relates to mounting members that are mounted on the surface of a finishing material that is exposed in a visible position in a building.

Conventionally, attaching other articles to a finishing material exposed at a visible position in a building has been performed by so-called DIY or by hand. As a technique related to this work, for example, the following Patent Document 1 discloses. The techniques used have been known. In this technique, other articles are locked to a mounting member fixed to the surface of the finishing material with a bug pin, and the other articles are attached to the finishing material.

Here, the insect pin has a configuration for pressing with a finger on the other end (also referred to as "head" in the present specification) of the rod-shaped fixing tool having one end piercing the object. However, it means that the effective slenderness ratio is relatively large. Of the rod-shaped fasteners with one end piercing the object, those having a structure for pressing the head with a finger are called "pushpins" or "pushpins". In addition, among rod-shaped fasteners with one end piercing the object, those that do not have a structure for pressing with a finger on the head and whose effective slenderness ratio is relatively small are called "nails". be called.

The difference between a bug pin and a nail appears in the method of piercing an object. In other words, the effective slenderness ratio of a nail is relatively small, and it hardly deforms even when a striking force (a large force applied momentarily) is applied. Therefore, when piercing an object, it hits the head of the nail. A method of applying force is adopted. On the other hand, the insect pin has a relatively large effective slenderness ratio, and when a force is applied to it, it often deforms as if it buckled or buckled. A method is adopted in which a pressing force large enough to prevent the pin from buckling is continuously applied to the head of the insect pin.

In the prior art described in Patent Document 1, the attachment member needs to have a shape that allows the other article to be locked in correspondence with the other article to be attached, and therefore can be attached. It was not very versatile for goods.

The present invention provides a mounting member with improved versatility for a mountable article.

According to one feature of the present invention, there is provided an attachment member that is attached to the surface of a finishing material, which is a member that is exposed in a visible position in a building. This mounting member forms a plate arranged along the surface of the finishing material, and includes a base material that can be stabbed to the surface by a bug pin. Further, the mounting member includes a fastener that protrudes from the base material in a direction away from the surface of the finishing material and is capable of fastening another fastening structure.

According to the above-mentioned attachment member, a state in which the fastener is projected from the surface of the finishing material can be realized, and an article of any shape having a fastening structure capable of being fastened to the fastener can be attached. As a result, the above-mentioned mounting member is improved in versatility for an article that can be mounted on the mounting member.

In the above mounting member, the fastener preferably has a screw thread that enables screwing another fastening structure into the fastener to fasten the fastener.

In this case, the fastener and the other fastening structure can be fastened by a simple operation of turning an article having the other fastening structure.

The above-mentioned mounting members preferably have an insertion structure into which the fastener can be inserted, and a base which is arranged so as to surround the periphery of the insertion structure and in a state where the fastener is inserted into the insertion structure. It is provided with a cap having an enclosure that allows other articles to be sandwiched between the material.

In this case, by inserting the fastener into the insertion structure of the cap and attaching the cap to the fastener, another article can be sandwiched and attached between the enclosure provided in the cap and the base material. As a result, the above-mentioned mounting member is improved in versatility for an article that can be mounted on the mounting member.

In this case, it is preferable that the fastener has a screwing structure that realizes that the fastener is screwed to the cap when the fastener is inserted into the insertion structure of the cap.

In this case, the attachment strength when attaching the cap to the fastener can be improved by the screwing structure, and the force for sandwiching another article between the enclosure portion provided on the cap and the base material can be increased.

In the above mounting member, the base material has a surface-like spread that is arranged so as to surround the root portion of the protrusion of the fastener on the front surface, which is the surface of the base material on the fastener side. Is preferable. In this case, the planar spread is arranged so as to spread in the direction along the surface of the base material when the back surface, which is the surface opposite to the front surface, faces the surface of the finishing material. Will be done. Further, the base material is provided with an inclined surface provided on the edge of the surface-like spread so as to spread from the front surface side to the back surface side of the base material. In addition, the base material is provided on the inclined surface in a state of being inclined toward the fastener side, and is provided with a through hole through which a bug pin for piercing the base material into the surface of the finishing material can be passed. ..

As described above, the insect pin pierces the object by continuously applying a pressing force large enough to prevent the insect pin from buckling to the head of the insect pin. In addition, the insect pin does not have a structure for pressing the head with a finger. Therefore, when the member forming the plate is pierced to the surface of the finishing material by the insect pin, the head of the insect pin is often pressed with a dent.

Here, in the above-mentioned mounting member, when the head of the insect pin passed through the through hole of the base material is pressed with a dent to prevent the base material from being pierced, the fastener and the dent interfere with each other. To avoid this, the tip of this dent should be tilted toward the fastener. Therefore, in the above case, the dent that has pushed the insect pin completely hits the inclined surface of the base material, and the ride from this inclined surface to the base material is induced. As a result, it is possible to reduce the possibility that the dent that has pushed the insect pin completely hits the surface of the finishing material and leaves a mark on the surface.

In this case, it is preferable that a plurality of through holes are arranged so as to surround the root portion of the protrusion of the fastener. In this case, the through holes have a positional relationship in which the insect pins that are passed through the through holes are tilted to one side in the circumferential direction surrounding the root portion of the fastener so that the insect pins are twisted to each other. To do. The through hole then positions these insect pins on one virtual hyperboloid with a constriction inside the finishing material.

In this case, in the plurality of insect pins that pierce the surface of the finishing material, the portion inside the finishing material has a hyperboloid structure in which the constriction is inside the finishing material as a whole. Thereby, the holding power of the plurality of insect pins to hold the base material on the surface of the finishing material can be improved. Further, since these insect pins have a positional relationship in which they are twisted with each other, it is possible to reduce the possibility of interference with other insect pins when the insect pin is inserted or pulled out.

The mounting member of the present invention can be provided as having improved versatility for a mountable article.

<First Embodiment>
First, the mounting member 10 according to the first embodiment will be described with reference to FIGS. 1 to 11. As shown in FIG. 1, the attachment member 10 is attached to the surface 90A of the finishing material 90, which is a member exposed at a visible position on the inner wall of the building, and another article (for example, a hole) is attached to the surface 90A. It is possible to attach the board 91). Here, the perforated board 91 shown in FIG. 1 is a plate material in which a large number of through holes 91A are formed in the plate surface at equal intervals.

As shown in FIG. 3, the mounting member 10 includes a base material 20, a plurality of (four in this embodiment) insect pins 13, a fastener 11, and a cap 12. .. The base material 20 forms a plate arranged along the surface 90A of the finishing material 90. The insect pin 13 pierces the base material 20 against the surface 90A of the finishing material 90. The fastener 11 is projected from the plate surface on one side of the base material 20. The cap 12 is detachably attached to the fastener 11. Here, in the following, the surface of the base material 20 on the fastener 11 side is referred to as the front surface 21, and the surface opposite to the front surface 21 is referred to as the back surface 20A.

As shown in FIGS. 4 and 11, the fastener 11 is a metal screw in which the head portion 11C is embedded in the plate of the base material 20. This structure can be made by insert molding in which the base material 20 is molded by filling the resin so as to wrap the head portion 11C of the fastener 11.

Further, in the state where the back surface 20A of the base material 20 faces the surface 90A of the finishing material 90 (see FIG. 4), the fastener 11 has a portion other than the head portion 11C separated from the surface 90A of the finishing material 90. It is arranged so as to protrude in the direction. As a result, as shown in FIG. 3, the fastener 11 is locked by hooking a hole or dent (specifically, for example, a through hole 91A of the perforated board 91) that can be locked to the protrusion, and thus the hole or the hole or a dent. It is possible to attach an article having a dent (specifically, for example, a perforated board 91) to the finishing material 90.

In the present embodiment, as shown in FIGS. 4 and 6, the fastener 11 has a male thread 11A at a portion other than the root portion 11B adjacent to the base material 20 when protruding from the base material 20. It is configured with. The screw thread 11A can be fastened by screwing another fastening structure into the fastener 11. For example, as shown in FIG. 12, the fastener 11 can fasten a hook 92 having a female screw fastening structure 92A by screwing the fastening structure 92A. Then, another article (not shown in FIG. 12) is hooked on the hook 92 to lock the hook 92, so that the other article can be attached to the finishing material 90.

As shown in FIGS. 4 and 6, the base material 20 has a configuration in which a planar spread 21A is arranged on the front surface 21 so as to surround the root portion 11B in the protrusion of the fastener 11. The planar spread 21A is arranged so as to spread in the direction along the surface 90A when the back surface 20A of the base material 20 faces the surface 90A of the finishing material 90 (see FIG. 4). It becomes.

Further, in the base material 20, the edge of the planar spread 21A is provided so as to spread from the front surface 21 side to the back surface 20A side of the base material 20 as shown in FIGS. 2 to 6. It is surrounded by an inclined surface 21B (see FIG. 3). As shown in FIGS. 4 and 6, a plurality of insect pins 13 (see FIG. 3) for sticking the base material 20 to the surface 90A of the finishing material 90 are passed through the inclined surface 21B (in the present embodiment). (For example, four) through holes 21C are arranged so as to surround the root portion 11B in the protrusion of the fastener 11 (see FIG. 6).

As shown in FIGS. 4 and 11, each of these through holes 21C is provided in a state of being inclined toward the fastener 11. Further, the through hole 21C tilts the insect pin 13 passed through each of the through holes 21C to one side (counterclockwise side in FIG. 11) in the circumferential direction surrounding the root portion 11B (see FIG. 4) of the fastener 11. It is provided as follows. As a result, the through holes 21C have the insect pins 13 passed through the through holes 21C in a positional relationship in which they are twisted to each other, and these insect pins 13 are arranged as one virtual single-leaf hyperboloid 10A (FIG. 3 to 5)). As shown in FIGS. 3 and 4, the constriction 10B of the single-leaf hyperboloid 10A is located inside the finishing material 90.

As shown in FIG. 10, the insect pin 13 has a tip 13A that pierces an object (for example, the finishing material 90 shown in FIG. 4) at one end of the body portion 13C having a long shaft shape, and the head 13B that is the other end. Is a locking projection that can be locked to another member (for example, the edge of the through hole 21C shown in FIG. 4). The head 13B has a disk shape (see FIG. 6) that is the same as the body 13C of the insect pin 13 and the central axis, but this disk is smaller in size than the fingers of a human hand (not shown). , It cannot be said that the configuration is for pressing with a finger. Further, the effective slenderness ratio of the body portion 13C of the insect pin 13 is increased to such an extent that the body portion 13C of the insect pin 13 is often deformed as if buckling or buckling was caused by applying an attack force.

Further, on the side surface of the body portion 13C, a plurality of rings 13D each having a truncated cone shape having a large diameter toward the other end side are connected in the longitudinal direction (vertical direction in FIG. 10) of the body portion 13C. It is provided. These rings 13D function as a stopper that makes it difficult for the insect pin 13 to come off from the object pierced by the insect pin 13. Further, when the insect pin 13 is pulled out from the object pierced by the insect pin 13, the ring 13D exerts a function of making the puncture mark inconspicuous by scratching and breaking the wall of the hole that becomes the puncture mark. The function of making the stab marks inconspicuous appears prominently in the insect pin 13 of the present disclosure in which the effective slenderness ratio of the body 13C is relatively large, but the effective slenderness ratio of the body is relatively large (for example, the impact force). It is so weak that it cannot be recognized with a small nail (to the extent that it hardly deforms even when acted on).

As shown in FIGS. 4 and 9, the cap 12 has four ribs of an insertion structure 12B into which the fastener 11 (see FIG. 4) can be inserted and an enclosure 12A surrounding the insertion structure 12B. It has a 12D connection. Here, the insertion structure 12B forms a bottomed cylinder in which a female screw fastening structure 12C is formed therein. Further, as shown in FIGS. 6 to 9, the enclosure 12A forms a bottomed cylinder having the same central axis and bottom as the insertion structure 12B, and the insertion structure 12B is housed in the bottomed cylinder. Is arranged in.

Further, as shown in FIGS. 6 and 9, the four ribs 12D surround the insertion structure 12B housed in the enclosure 12A at equal intervals and project radially from the outer surface of the insertion structure 12B. Make a board. In the present embodiment, the plates of the ribs 12D are arranged so as to extend in the direction in which the bottomed cylinders of the insertion structure 12B and the enclosure 12A extend (the direction perpendicular to the paper surface as seen in FIG. 9). ..

Here, the female screw fastening structure 12C in the insertion structure 12B and the male screw thread 11A in the fastener 11 form a screw structure that can be fastened by screwing as shown in FIG. This screwing structure realizes that when the fastener 11 is inserted into the insertion structure 12B of the cap 12, the fastener 11 is screwed to the cap 12.

Further, as shown in FIG. 3, the enclosure portion 12A is capable of sandwiching another article between the enclosure portion 12A and the base material 20 when the fastener 11 is inserted into the insertion structure 12B. For example, in a state where the through hole 91A of the perforated board 91 is caught and locked by the fastener 11, the fastener 11 is inserted into the insertion structure 12B and screwed to connect the base material 20 and the enclosure 12A. The space between them can be narrowed so that the edge of the through hole 91A in the perforated board 91 can be sandwiched between them.

In the above case, the perforated board 91, which is an article sandwiched between the surrounding portion 12A and the base material 20, is pressed by the surrounding portion 12A and follows the planar spread 21A of the base material 20. Located in. Therefore, the through hole 91A of the perforated board 91 is caught and locked by the root portion 11B without the screw thread 11A in the fastener 11.

According to the mounting member 10 described above, an article having an arbitrary shape having a fastening structure capable of realizing a state in which the fastener 11 protrudes from the surface 90A of the finishing material 90 and fastening the fastener 11 to the fastener 11 ( For example, the hook 92) having the fastening structure 92A shown in FIG. 12 can be attached. As a result, the mounting member 10 is improved in versatility for articles that can be mounted on the mounting member 10.

Further, in the above-mentioned mounting member 10, the fastening between the fastener 11 and the other fastening structure is as simple as turning an article having the other fastening structure (for example, the hook 92 having the fastening structure 92A shown in FIG. 12). It can be done by various operations.

Further, according to the mounting member 10 described above, by inserting the fastener 11 into the insertion structure 12B of the cap 12 and attaching the cap 12 to the fastener 11, the enclosure portion 12A provided on the cap 12 and the base material are provided. Another article (for example, the perforated board 91 shown in FIG. 3) can be sandwiched and attached between the 20 and the 20. As a result, the mounting member 10 is improved in versatility for articles that can be mounted on the mounting member 10.

Further, according to the mounting member 10 described above, the mounting strength when the cap 12 is mounted on the fastener 11 is the screw formed by the female screw fastening structure 12C in the insertion structure 12B and the male thread 11A in the fastener 11. It can be improved by the combined structure. As a result, the mounting member 10 can increase the force for sandwiching another article (for example, the perforated board 91 shown in FIG. 3) between the surrounding portion 12A provided on the cap 12 and the base material 20.

Further, according to the mounting member 10 described above, the fastener 11 has a configuration in which a hole or a dent (specifically, for example, a through hole 91A of a perforated board 91) is hooked and locked in a root portion 11B without a screw thread 11A. , The possibility that the thread 11A of the fastener 11 is crushed by the article having the hole or the dent (specifically, for example, the perforated board 91) can be reduced.

Here, in the mounting member 10 described above, the head 13B of the insect pin 13 passed through the through hole 21C of the base material 20 is pressed by the dent 93 (see FIG. 4) to prevent the base material 20 from being pierced. When this happens, the tip of the dent 93 is tilted toward the fastener 11 in order to avoid interference between the fastener 11 and the dent 93. Therefore, according to the mounting member 10 described above, the dent 93 that has pushed the insect pin 13 completely hits the inclined surface 21B of the base material 20, and the ride from the inclined surface 21B to the base material 20 is guided. As a result, it is possible to reduce the possibility that the dent 93 that has pushed the insect pin 13 completely hits the surface 90A of the finishing material 90 and leaves a mark on the surface 90A.

Further, according to the mounting member 10 described above, in the plurality of insect pins 13 for sticking the base material 20 to the surface 90A of the finishing material 90, the portion inside the finishing material 90 has a constriction 10B as a finishing material as a whole. It forms a hyperboloid structure inside the 90. Thereby, the holding force of the plurality of insect pins 13 to hold the base material 20 on the surface 90A of the finishing material 90 can be improved. Further, since these insect pins 13 have a positional relationship in which they are twisted with each other, it is possible to reduce the possibility of interference with other insect pins 13 when the insect pins 13 are inserted or pulled out.
