Description

  The present invention relates to an adhesive-type fixing tool having an adhesive material as a fixing element, a fixing method thereof, and a handrail structure provided with the adhesive-type fixing tool.

  Regarding the adhesive-type fixing tool of the present invention, the suction disk of Patent Document 1 is known, and the fixing tool is fixed to a wall surface or the like by the suction action of the suction board and the adhesive action of the adhesive material. Specifically, a disc-shaped pedestal, a suction lip housed on the inner surface of the pedestal, a decompression cam that moves up and down an operation shaft fixed to the center of the suction lip, and a re-adhesive adhesive that is attached to the inner edge of the pedestal The suction disk (fixing tool) is composed of a sheet or the like. The suction lip is composed of an elastomer layer and an adhesive layer provided on the suction surface side of the elastomer layer. The adhesive layer and the operating shaft are inserted and integrated in the process of forming the elastomer layer. This suction disk is made by pressing the adhesive layer of the suction lip and the adhesive sheet provided on the pedestal against the wall at the same time, and then operating the operating shaft supported by the pedestal with a decompression cam to make the suction surface of the suction lip a dish-like shape. It is kept in a fixed state by being recessed and decompressed.

  Although the fixing tool of the present invention fixes the fixing tool to the wall surface only by the adhesive action of the adhesive material, a similar adhesive-type fixing tool is disclosed in Patent Document 2, for example. There, there are a fixing ring, a disk that is rotatably supported on the inner surface of the fixing ring and that is supported so as to be movable toward and away from the wall surface, a pressure-sensitive adhesive layer provided on the bonding surface of the fixing ring, and a bonding surface of the disk. A fixing tool is constituted by a hot melt adhesive layer provided on the substrate. In use, the fixing ring is pressed against the wall surface to temporarily bond the entire fixing tool. In addition, the drive bit of the electric drill is engaged with the socket hole provided in the center of the outer surface of the disk, and the hot melt adhesive layer is melted with frictional heat and fixed by rotating the disk while pressing the disk against the wall surface. Secure the tool to the wall. That is, the fixing tool of Patent Document 2 fixes the fixing tool to the wall surface with the adhesive force of the pressure-sensitive adhesive layer and the adhesive force when the hot melt adhesive layer is solidified.

JP 2006-308025 A (paragraph numbers 0028 to 0029, FIG. 1) Japanese National Patent Publication No. 10-510032 (page 15, lines 1 to 26, FIG. 2)

  According to the suction disk of Patent Document 1, the suction disk can be firmly fixed to the wall surface by the vacuum suction action of the suction lip and the adhesive action of the adhesive layer and the adhesive sheet. However, when the suction disk is fixed to the wall surface, the pressure-sensitive adhesive layer provided on the suction lip is also recessed in a dish shape together with the elastomer layer, so that the reduced pressure state is easily destroyed depending on the surface condition of the wall surface. The pressure-sensitive adhesive layer with the adsorber fixed is in close contact with the wall only at the peripheral edge, but the decompression state breaks down when the wall has gentle irregularities across the previous contact surface in the radial direction. There is a risk of being. Therefore, in consideration of safety, wall surfaces to which the suction disk can be applied without problems are limited to relatively flat wall surfaces such as tile walls and glass surfaces.

  In that respect, since the pressure-sensitive adhesive layer and the hot melt adhesive layer are each concentrically bonded to the wall surface, the adhesive-type fixing device of Patent Document 2 can be fixed to the wall surface in a stable state. Moreover, the range of applicable wall surfaces can be expanded. However, since the hot melt adhesive layer is melted and fixed by frictional heat with the wall surface, there is a problem in that the fixing strength of the fixing tool to the wall surface tends to vary. The coefficient of friction varies greatly depending on the surface properties of the wall surface, and the melt state of the hot melt adhesive layer changes in various ways. Further, the melting degree of the hot melt adhesive layer varies depending on the experience of the operator. It is.

  Unlike the adhesive-type fixing tool of Patent Document 2, the adhesive-type fixing tool according to the present invention presses each of a circular adhesive part and an endless frame-like adhesive part surrounding the adhesive part against the wall surface. Although it adheres, even in this kind of all-adhesive type fixing tool, there is a problem that the fixing strength tends to vary. In many cases, when the adhesive part is pressed against the wall surface, each adhesive part is not pressed with sufficient force, the pressing force is locally biased, and each adhesive part is pressed. The cause is that air is stuck in the adhesive surface.

  The adhesive-type fixing tool of the present invention is applied as an attachment structure for handrails installed in, for example, entrances, toilets, bathrooms, etc. It is required to have safety and reliability. In order to be able to exhibit a high degree of safety and reliability in an all-adhesive type fixing tool, it is the most basic matter that the fixing strength of the fixing tool fixed to the wall surface is sufficient. However, as mentioned earlier, the adhesive strength of adhesive-type fasteners varies depending on the presence or absence of the operator's experience at the time of construction, and the adhesive strength after construction satisfies the design strength. Not a few situations have occurred.

The object of the present invention is to enable anyone to properly fix an adhesive-type fixing tool regardless of whether there is work experience or not, and to exhibit sufficient fixing strength, with high safety and excellent reliability. It is to provide an adhesive-type fixing tool.

It is. As shown in FIG. 1, the air chamber 16 is formed in a recess in the direction away from the fixing surface W near the center of the adhesive surface 10 a of the first adhesive material 10.

  The spacer 29 is formed of an elastic body that can be elastically deformed in the axial direction of the fastening shaft 14. In a state where the second adhesive tool 6 is fixed by the fixing tool 41, the spacer 29 is compressed and deformed within its own elastic deformation limit.

  A circular first adhesive material 10 is disposed on a first adhesive base 8 formed in a disk shape of the first adhesive tool 5. On the second adhesive base 18 formed in the polygonal shape of the second adhesive 6, a circular second adhesive material 20 whose outer peripheral shape is a polygon and whose inner peripheral shape surrounds the first adhesive material 10 is disposed.

  As shown in FIG. 8, the fixture for fixing the second adhesive 6 is constituted by a pressing cam 41 that is connected to the fastening shaft 14 via a pin 55 so as to be able to fall down. The pressing cam 41 includes a first cam surface 58 and a second cam surface 59 that respectively contact the cam receiving surface 60 on the outer surface of the second adhesive base 18. The spacer 29 is compressed and deformed by tilting the pressing cam 41 from the standby position where the first cam surface 58 contacts the cam receiving surface 60 to the operating position where the second cam surface 59 contacts the cam receiving surface 60. Then, the bonding surface 20a of the second adhesive 6 is bonded to the fixing surface W.

  The fixing tool according to the fixing method of the present invention includes a first adhesive tool 5 that is pressed and adhered to the fixing surface W, a second adhesive tool 6 that is assembled to a fastening shaft 14 provided on the first adhesive tool 5, and a cover 7. And a spacer 29 that is disposed between the first adhesive tool 5 and the second adhesive tool 6 and holds the second adhesive tool 6 in the adhesion standby state. The adhering method is a primary adhering process in which only the adhesive surface 10a of the first adhesive 5 is pressed against the adhering surface W in a state where the second adhesive 6 is held in the adhesion standby state. The second adhesive 6 is displaced toward the fixing surface W by the fixture 41 assembled to the fastening shaft 14, and the adhesive surface 20 a of the second adhesive 6 is bonded to the fixing surface W while compressing and deforming the spacer 29. Secondary bonding process. This includes a pressing and holding process in which the cover 7 is pressed against the second adhesive 6 by the fixing tool 42 assembled to the fastening shaft 14 and the adhesive surface 20a of the second adhesive 6 is strongly pressed against the fixing surface W.

  The handrail structure provided with the adhesive type fastener according to the present invention includes a plurality of adhesive type fasteners 1, 1, a plurality of handrail brackets 2, 2 assembled to each of the fasteners 1, 1, The handrail rod 3 supported by the handrail brackets 2 and 2 is provided. The fixing tool 1 includes a first adhesive tool 5 and a second adhesive tool 6 that are pressed against and adhered to the fixing surface W, and a cover 7 that covers the outer surface of the second adhesive tool 6. The second adhesive 6 is fixed to the first adhesive 5 with a fastening shaft 14 provided on the first adhesive 5 and a fixture 41 assembled to the fastening shaft 14. Between the first adhesive tool 5 and the second adhesive tool 6, a spacer 29 that holds the second adhesive tool 6 in the adhesion standby state is disposed. In a state where only the adhesive surface 10a of the first adhesive tool 5 is adhered to the fixing surface W, the second adhesive tool 6 is displaced toward the fixing surface W while the spacer 29 is compressed and deformed by the fixing tool 41, so that the second adhesive The adhesive surface 20a of the tool 6 is bonded to the fixing surface W. The handrail bracket 2 is fixed to the first adhesive 5 via the second adhesive 6 together with the cover 7 with a nut 42 screwed onto the fastening shaft 14.

  In the present invention, the first adhesive tool 5, the second adhesive tool 6, the cover 7, the spacer 29 arranged between the two adhesive tools 5, 6, and the fastening shaft for fixing the second adhesive tool 6 and the cover 7. 14 and the fixtures 41 and 42, etc., constitute the fixture 1. When the fixing tool 1 is fixed to the fixing surface W, only the adhesive surface 10a of the first adhesive tool 5 is bonded to the fixing surface W in a state where the second adhesive tool 6 is held in the bonding standby state by the spacer 29. . Further, the second adhesive tool 6 is displaced toward the fixing surface W by the fixing tool 41, and the adhesive surface 20 a of the second adhesive tool 6 is bonded to the fixing surface W while compressing and deforming the spacer 29.

  As described above, in the fixing tool 1 of the present invention, the first adhesive tool 5 bonded to the fixing surface W is used as a base, and the second adhesive tool 6 is supported by the fastening shaft 14 provided on the first adhesive tool 5. Then, the second adhesive tool 6 is mechanically displaced by the fixing tool 41 so as to adhere to the fixing surface W. In this way, when the two bonding tools 5 and 6 are sequentially bonded to the fixing surface W, the pressing force is insufficient and the pressing force is reduced as compared with the case where one bonding tool having the same bonding area is bonded to the fixing surface suddenly. Local bias or air entrainment can be avoided as much as possible. When the first adhesive tool 5 is bonded to the fixing surface W, the second adhesive tool 6 is held in the adhesive standby state by the spacer 29, so that only the first adhesive tool 5 needs to be bonded. This is because the adhesive 5 can be accurately pressed against the fixing surface W. In addition, since the second adhesive tool 6 supported by the fastening shaft 14 is mechanically displaced by the fixing tool 41 and the second adhesive tool 6 is adhered to the fixing surface W by the pressing force of the fixing tool 41, 2 because the adhesive 6 can be bonded accurately with a sufficient pressing force.

  Therefore, according to the fixing tool of the present invention, regardless of whether or not there is work experience, anyone can fix the adhesive-type fixing tool 1 properly and exert a sufficient fixing strength, and in particular, support the human weight. When the fixture 1 is used as a fixture mounting structure, safety and reliability can be improved. Further, since each of the first adhesive tool 5 and the second adhesive tool 6 is adhered and fixed to the fixing surface W, there is also an advantage that the fixing tool 1 can be attached irrespective of the difference in surface properties of the fixing surface W. .

  According to the fixing tool 1 that presses the second adhesive tool 6 against the fixing surface W with the pressing body 35 provided in the cover 7 in the assembled state of the cover 7, the pressing of the fixing tool 41 acting on the second adhesive tool 6 is performed. The pressure and the pressing force of the fixture 42 that acts on the cover 7 can be simultaneously applied to the adhesive surface 20a. Further, the pressing body 35 can be pressed and held by the pressing body 35, and the pressing body 35 can regulate the peeling of the adhesive surface 20 a from the fixing surface W. Therefore, the fixing tool 1 can be further firmly fixed to the fixing surface W, and the safety and reliability of the fixing tool 1 can be further improved.

  If the air chamber 16 is formed in a recess near the center of the adhesive surface 10a of the first adhesive material 10, when the first adhesive tool 5 is pressed against the fixing surface W and bonded, the first adhesive material 10 and the fixing surface W The air sandwiched between them can be moved to the air chamber 16. Thereby, all the adhesive surfaces 10a of the first adhesive material 10 excluding the air chamber 16 can be adhered to the fixing surface W, and the fixing strength of the first adhesive device 5 can be enhanced, and the fixing strength of the first adhesive device 5 can be increased. The second adhesive 6 and the cover 7 can be fixed in a more stable state by the larger amount.

  According to the fixing tool 1 in which the spacer 29 is formed of an elastic body elastically deformable in the axial direction of the fastening shaft 14 and the second adhesive tool 6 is fixed, and the spacer 29 compressively deforms within its own elastic deformation limit. In this case, it is possible to repeatedly attach and detach the fixing tool 1 to and from the fixing surface W. For example, when the position of the fixing device 1 fixed to the fixing surface W is not appropriate, when the fixing state by the fixing devices 41 and 42 is released, the spacer 29 can be expanded and returned to the state before compression. The attachment and detachment with respect to the fixing surface W can be repeated repeatedly. Incidentally, the spacer 29 can be formed of a material that is plastically deformed and crushed in a state in which the second adhesive tool 6 is fixed by the fixing tool 41. In this case, the fixing position of the fixing tool 1 with respect to the fixing surface W is fixed. Each time is changed, it is necessary to replace the spacer 29 with a new one, which takes extra time.

  In the fixing device 1 in which the second adhesive base 18 is provided with the polygonal second adhesive material 20 containing the first adhesive material 10, the outer surface of the second adhesive base 18 is covered with the pressing body 35 provided on the inner surface of the cover 7. When pressed, the entire second adhesive material 20 can be firmly pressed against the fixing surface W. In particular, it is possible to increase the fixing force of the fixing tool 1 by firmly pressing the vicinity of the corners of the polygonal second adhesive material 20 where the pressing force by the fixing tool 41 hardly acts with the pressing body 35.

  According to the fixing tool 1 in which the fixing tool is constituted by the pressing cam 41, the spacer 29 is compressed and deformed by a one-touch operation of simply tilting the pressing cam 41 from the standby position to the operating position, and the adhesive surface of the second adhesive tool 6. 20a can be bonded to the fixing surface W. Accordingly, the second adhesive tool 6 can be easily fixed to or removed from the fixing surface W, and the fixing force of the pressing cam 41 is always constant, so that the second adhesive tool 6 is always fixed with a sufficient fixing force. It can be fixed properly.

  In the fixing method of the present invention, only the first pressure-sensitive adhesive tool 5 is bonded to the fixing surface W in the primary bonding process, and the second pressure-sensitive adhesive tool 6 is bonded to the fixing surface W with the fixing tool 41 in the secondary bonding process. During the pressing and holding process, the cover 7 is pressed against the second adhesive 6 by the fixing tool 42 so that the adhesive surface 20a is strongly pressed against the fixing surface W. As described above, when the first adhesive tool 5, the second adhesive tool 6, and the cover 7 are sequentially operated to fix the fixing tool 1 to the fixing surface W, one adhesive tool having the same bonding area is suddenly fixed. Compared with the case where the adhesive is adhered, it is possible to avoid a pressing force shortage, a local uneven pressing force, or air entrainment as much as possible. Therefore, according to the method for fixing the adhesive type fixing tool of the present invention, anyone can properly fix the adhesive type fixing tool 1 and exhibit sufficient fixing strength, regardless of whether there is work experience or not. When the fixture 1 is used as a mounting structure for an instrument that supports a person's weight, safety and reliability can be improved.

  In the handrail structure according to the present invention, the first adhesive tool 5 bonded to the fixing surface W is used as a base, the second adhesive tool 6 is bonded to the fixing surface W, and then the handrail bracket 2 and the cover 7 are both connected by the nuts 42. The handrail bar 3 is connected to the handrail bracket 2 by being mechanically fixed to the adhesive tools 5 and 6. Thus, when the handrail structure is constructed by using the first adhesive tool 5 and the second adhesive tool 6 bonded to the fixing surface W as a support structure, the fixing tool 1 is not affected by the surface properties of the fixing surface W. Can be securely fixed to the fixing surface W, so that the range of application of the handrail structure can be expanded. Further, since the second adhesive tool 6, the handrail bracket 2, and the cover 7 are mechanically fixed by operating the fixing tool 41 and the nut 42, anyone can use the adhesive-type fixing tool regardless of whether or not there is work experience. Can be adequately fixed to exhibit sufficient fixing strength, and the safety and reliability of the handrail structure provided with the adhesive-type fixing tool can be improved.

  In the secondary bonding process, the adhesive surface 20 a of the second adhesive tool 6 is pressed against the fixing surface W with a nut (fixing tool) 41 assembled to the fastening shaft 14 and bonded. Specifically, the second adhesive 6 can be brought close to the fixing surface W while the spacer 29 is compressed and deformed by screwing the nut 41 temporarily assembled to the fastening shaft 14. In a state where the nut 41 is sufficiently screwed as shown in FIG. 7B, the adhesive surface 20 a of the second adhesive tool 6 can be forcibly pressed and adhered to the fixing surface W by the fastening force of the nut 41.

  As described above, the first adhesive tool 5 previously fixed to the fixing surface W is used as a base, and the second adhesive tool 6 is fixed to the fixing surface W with the nut 41 using the fastening shaft 14 fixed to the first adhesive tool 5. When the pressure is too high, the second adhesive 6 can be accurately fixed to the fixing surface W regardless of the experience of the operator. At this time, as shown in FIG. 7B, a circular area concentric with the adhesive surface 10 a of the first adhesive tool 5 is firmly bonded to the fixing surface W among the adhesive surfaces 20 a formed in a square shape. The spacer 29 in a state where the second adhesive tool 6 is fixed to the fixing surface W is compressed and deformed within its own elastic deformation limit. Therefore, when the nut 41 is loosened, it can be expanded to return to the state before compression.

  In the pressing and holding process, the cover 7 is fixed to the second adhesive 6 with a plastic nut (fixing tool) 42 assembled to the fastening shaft 14. Specifically, as shown in FIG. 7C, the cover 7 is inserted into the fastening shaft 14, and the insertion hole 50 of the fastening seat 49 is fastened in a state where the connecting seat 48 of the bracket body 46 is externally fitted to the boss 21. The shaft 14 is inserted. Further, the plastic nut 42 is screwed into the fastening shaft 14 via a plain washer, and the bracket body 46 and the cover 7 are fixed to the second adhesive tool 6. In a state where the plastic nut 42 is sufficiently tightened, the connecting seat 48 of the bracket body 46 and the receiving seat 32 of the cover 7 adjacent to the connecting seat 48 are in close contact with each other, and the pressing body 35 provided on the inner surface of the cover 7 Strong pressure is applied to the outer surface of the second adhesive tool 6. Thereby, the adhesive surface 20 a of the second adhesive tool 6 can be reliably pressed against the fixing surface W by the circular rib 36 and the square rib 37. In particular, the four corner regions of the pressure-sensitive adhesive surface 20a, which tends to have insufficient pressing force in the secondary bonding process, can be securely bonded to the fixing surface W by strongly pressing the corner ribs 38.

  After the handrail bracket 2 is integrated with the fixing tool 1, the fastening block 52 fixed to the end of the handrail rod 3 is inserted into the connecting tube portion 45 of the bracket body 46, and the screw 53 inserted through the screw seat 51 is connected to the fastening block 52. The handrail rod 3 can be fixed by screwing it into (see FIG. 1). Similarly, the handrail structure can be attached to the fixing surface W by fastening the other end of the handrail bar 3 to the bracket body 46 with the screw 53.

  According to the adhesive-type fixing tool described above, after the first adhesive tool 5 having a relatively small area is bonded to the fixing surface W, the nut 41 screwed into the fastening shaft 14 using the first adhesive tool 5 as a base. Thus, the second adhesive 6 can be mechanically pressed against the fixing surface W. Therefore, it is possible to eliminate the variation in the fixing force of the first adhesive tool 5 and the second adhesive tool 6 to the fixing surface W by the operator. Further, the first adhesive tool 5 and the second adhesive tool 6 are not locally pressed against the fixing surface W. Further, when the first adhesive 5 is bonded to the fixing surface W, the air sandwiched between the first adhesive material 10 and the fixing surface W is moved to the air chamber 16 so that the first adhesive excluding the air chamber 16 is removed. All of the adhesive surface 10a of the material 10 can be brought into close contact with the fixing surface W.

  Therefore, regardless of whether or not the operator has experience, anyone can properly fix the adhesive-type fixing tool 1 to the fixing surface W and exhibit sufficient fixing strength. Further, even if the fixing tool 1 is applied as a support structure for an instrument that supports the weight of a person, the fixing tool 1 can be fixed to the fixing surface W in a state satisfying a high degree of safety and reliability. Unlike the fixing tool that melts the hot melt adhesive layer by frictional heat with the wall surface, the adhesive surfaces 10a and 20a of the first and second adhesive tools 5 and 6 are bonded to the fixing surface W, respectively. Therefore, there is an advantage that the fixing tool 1 can be reliably fixed to the fixing surface W without being influenced by the difference in the surface properties of the fixing surface W.

  8 and 9 show another embodiment of the fastener. There, the second adhesive tool 6 can be fixed to the first adhesive tool 5 with a pressing cam (fixing tool) 41 that is tiltably connected to the fastening shaft 14 via a pin 55. The pressing cam 41 is integrally provided with a pair of cam plates 56 sandwiching the fastening shaft 14 and an operation boss 57 that bridges the cam plates 56, and a first cam surface 58 is provided on the circumferential surface of the cam plate 56. A second cam surface 59 is formed.

  A flat cam receiving surface 60 for receiving both cam surfaces 58 and 59 is formed at the outer end of the boss 21 of the second adhesive base 18. As shown in FIG. 9, the pressing cam 41 is in a standby position where the first cam surface 58 contacts the cam receiving surface 60, and the second cam surface 59 contacts the cam receiving surface 60 as shown in FIG. It can be tilted around the pin 55 between the positions. In a state where the pressing cam 41 is tilted to the operating position, the adhesive surface 20a of the second adhesive tool 6 can be bonded to the fixing surface W with one touch while the spacer 29 is contracted and deformed. As shown in FIG. 9, the posture of the pressing cam 41 is switched by the operation shaft 61 inserted into and engaged with the operation boss 57. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  In the above embodiment, the cover 7 is fastened together with the bracket body 46 by the plastic nut 42, but this is not necessary, and a structure corresponding to the connecting seat 48 and the fastening seat 49 of the bracket body 46 is formed integrally with the cover 7. Then, the cover 7 can be directly fastened with the plastic nut 42. In addition, the latching hook or the hanging ring can be fastened together with the cover 7 with the plastic nut 42, and the latching hook and the hanging ring can be fixed to the fixing surface W through the fixing tool 1.

  In the above embodiment, the spacer 29 is formed of a rubber molded product that can be elastically deformed. However, the spacer 29 is not necessary, and can be formed of a compression coil spring, a disc spring, a torsion coil spring, or the like. The spacer 29 can be formed of a material that is plastically deformed and crushed when the nut 41 is tightened to the end. In that case, after the second adhesive 6 attached to the fixing surface W is once removed from the first adhesive 5, a new spacer 29 is assembled to the fastening shaft 14 to fix the fixing tool to the fixing surface W. 1 can be mounted without hindrance.

  The external shape of the second adhesive tool 6 can be formed in a circular shape, an elliptical shape, or a polygonal shape other than a square shape. Since the structure of the pressing body 35 should be changed as appropriate according to the difference in the outer shape of the second adhesive tool 6, it is not limited to the structure described in the embodiment. For example, when the outer shape of the second adhesive tool 6 is circular, the corner ribs 38 can be omitted and the pressing body 35 can be formed with double circular circular ribs.
