Description

  The present invention relates to a fixture and an assembly-type fixture that can reliably hold a target fixing position and increase the working efficiency when the accessory is fixed to a support member via the fixture.

  Conventionally, as a fixture that can be attached to an arbitrary position of a support material, for example, the one described in Utility Model Registration No. 3105143 is known. Hereinafter, this fixture will be described with reference to FIGS. 4 and 5.

  FIG. 4 is an exploded perspective view showing a state in which the fixture is attached to the support member, and FIG. 5 is a cross-sectional view showing a state in which the fixture is attached to the support member.

  As shown in FIG. 4, a groove 114 is provided in the longitudinal direction of the support member 111, and a pair of a locking groove 112 and a locking protrusion 113 are formed on the inner surface of the groove 114. . On the other hand, the fixture 120 is provided with a plurality of screw holes 125 in the back plate portion 121, and a pair of wall surfaces 123 are provided from both side edges of the back plate portion 121. Locking ridges 124 are formed on the outer sides of the open ends of the pair of wall surfaces 123, respectively. Further, the inner side of the wall surface 123 is gradually narrowed toward the open end portion, and the inner surface of the open end portion of the wall surface 123 and the tip circumferential portion of the fixing screw 131 screwed into the screw hole 125. Are configured to contact each other.

  FIG. 5 shows a state in which the fixing device having such a configuration is attached to the support member 111. When the wall surface 123 is inserted inside the longitudinal groove 114 of the support member 111 with the locking protrusions 124 facing forward, the open ends of the pair of wall surfaces 123 come into contact with the locking protrusions 113 of the support material 111. The locking protrusion 124 of the wall surface 123 engages with the groove 114 of the support member 111. Next, when the fixing screw 131 is screwed into the screw hole 125 in this state, the tip circumferential portion comes into contact with the inner surface of the wall surface 123, and as described above, the inner side of the wall surface 123 gradually narrows toward the open end portion. Therefore, as the fixing screw 131 advances, the wall surface 123 expands to the inner facing wall surface of the groove 114 of the support material 111. As the fixing screw 131 is further screwed in, the expansion of the wall surface 123 proceeds, and eventually the outer surface of the wall surface 123 comes into pressure contact with the opposing wall surface of the groove 114 of the support member 111, thereby supporting the outer surface of the wall surface 123. The frictional force generated between the opposing walls of the groove 114 of the material 111 becomes strong, and the fixture is fixed to the support material 111.

  For example, when fixing a shelf board or the like to the support member using the fixture fixed to the support member 111 as described above, the screw hole 125 at a desired position among the screw holes 125 of the fixture is described above. Instead of the fixing screw 131, a locking screw (not shown) provided with a locking means is screwed, and the locking portion provided at the end of the shelf is locked by this locking screw. .

In such a fixture, the pair of wall surfaces 123 are fixed to the support material by being pressed against the inner facing wall surface of the groove 114 of the support material 111. The height of the shelf board can be selected freely.
Utility model registration No. 3105143

  However, in the conventional fixture, a pair of wall surfaces 123 are provided on both side edges of the back plate portion 121 over the entire length thereof, and a plurality of screw holes 125 are formed in the back plate portion 121. Since the fixing screws 131 are screwed into the screw holes 125 so as to spread the entire pair of wall surfaces 123 evenly, the wall surfaces 123 can be obtained simply by screwing a small number of fixing screws 131 into the screw holes 125. Cannot be sufficiently expanded, and the pressure contact force of the wall surface 123 with respect to the inner facing surface of the groove 114 of the support material 111 is insufficient, so that the fixed position is hardly held. Therefore, when a shelf board or the like is attached to the fixture fixed to the groove 114 of the support member 111, that is, when a large load in the direction perpendicular to the screwing direction is applied, the fixture is displaced in the groove 114, and the fixed position Can no longer hold.

  In addition, as described above, since the entire pair of wall surfaces 123 cannot be expanded evenly unless the fixing screws 131 are screwed into the plurality of screw holes 125, in other words, only one fixing screw 131 is provided. Since the pair of wall surfaces 123 cannot be expanded as long as they are screwed into the screw holes 125, it is necessary to use a plurality of fixing screws 131 when temporarily fixing the fixture to the support material. For this reason, there has been a problem that both the temporary fixing operation and the main fixing operation are extremely troublesome.

  Furthermore, the press contact of the wall surface 123 of the fixture with the inner facing surface of the groove 114 of the support member 111 is maintained by the tip circumferential portion of the fixing screw 131 contacting the inner surface of the wall surface 123 in a pressed state. The fixing screws may loosen and come off naturally over time, and there was a risk that accessories such as fixed shelf boards would fall off.

  Therefore, an object of the present invention is to provide a fixture that is extremely easy to fix to a support material and that does not risk dropping off, and an assembly-type fixture using the fixture.

  In order to solve the above-described problems, a fixing device according to the present invention includes a plurality of pairs of press-contacts that can be expanded on one surface of the back plate and can be press-contacted with the opposing wall surface of the locking groove and have a protruding edge on the inner surface. A fixing device main body in which the leg pieces are protruded in a row independently of each other, and screw holes are provided at a plurality of positions corresponding to the protruding positions of the pressure contact leg pieces on the back plate portion, and the fixing device main body A plurality of fixing screws that are screwed into the screw holes and are engaged with the protruding edge portions of the pressure contact leg pieces when being screwed to expand the pressure contact leg pieces and press-contact with the opposing wall surfaces of the locking grooves. It is characterized by that.

  According to the present invention as described above, since a plurality of pairs of pressure contact leg pieces pressed against the opposite wall surface in the locking groove provided in the support member are provided, each pressure contact leg piece is a conventional one. Expansion is extremely easy compared to the wall surface of the fixture. In addition, since screw holes are provided corresponding to the protruding positions of these pressure contact leg pieces, when temporarily fixing the fixture in the groove of the support material, either one pair of pressure contact leg pieces can be used. By screwing a fixing screw into the screw hole to be expanded, it can be easily expanded, and can be easily temporarily fixed in the groove of the support material. In addition, when the main fixing is performed, a fixing screw is screwed into each screw hole. As described above, since the pair of press contact leg pieces are expanded for each fixing screw, any screw is used. Entry work is also easy. In addition, since it is easy to expand each press contact leg piece, it is possible to obtain a reliable press contact force for each press contact leg piece, so that the fixing to the support member is ensured.

  In addition, by forcibly screwing the fixing screw between the protruding edge portions of the pressure contact leg piece through the screw hole, the fixing screw and the protruding edge portion are engaged with each other. Screws are prevented from loosening.

  In the fixture according to the present invention, the fixture main body may be made of aluminum die cast.

  The fixing screw may also serve as a mounting screw that engages with an object to be fixed.

  In this case, the fixing tool can be fixed to the support member and the fixed object can be engaged with the fixing tool with one mounting screw, and the number of parts can be reduced.

  In addition, the assembly type fixture according to the present invention can be expanded on one surface of the back plate portion and the plurality of support columns formed with the locking grooves along the axial direction, and can be pressed against the opposing wall surface of the locking grooves. In addition, a plurality of pairs of pressure contact leg pieces having protruding edges on the inner surface side are provided in a row independently of each other, and screws are provided at a plurality of locations corresponding to the protrusion positions of these pressure contact leg pieces on the back plate.

And a fixing tool main body in which screw holes are provided in a plurality of locations corresponding to the protruding positions of the pressure contact leg pieces of the back plate portion, and the screws of the fixing tool main body. A plurality of fixing screws which are screwed into the holes and engage with the protruding edge portions of the pressure contact leg pieces when being screwed to expand the pressure contact leg pieces and press-contact with the opposing wall surfaces of the locking grooves; When the fixing screws are screwed in, the pressure contact leg pieces corresponding to the screw holes are evenly expanded, and the pressing force toward the groove inner surface of the support member and the contact area become large. Fixing and main fixing operations are easy, and the fixed object is securely fixed to the support material. It is possible.

  Further, by screwing the fixing screw, the fixing screw expands the pressure contact leg piece and meshes with the protruding edge portion, so that there is no possibility that the fixing screw loosens and comes off.

  Furthermore, if it is made of aluminum die-casting, it becomes possible to cope with mass production in addition to being able to easily cope with processing of various shapes such as projecting edges.

  Further, if the fixing screw also serves as a mounting screw that engages with an object to be fixed, the fixing of the fixing tool to the support member and the engagement of the fixing object to the fixing tool can be performed with one mounting screw. Thus, the number of parts can be reduced and workability can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded perspective view showing an embodiment of a fixing device according to the present invention, and FIG. 2 is a cross-sectional view showing a state in which the fixing device is fixed to a support material.

  This fixing tool 20 is slidably inserted into a locking groove 12 provided in the support material 11, and is for fixing an object 60 (see FIG. 3) to the support material 11.

  This fixture 20 includes a die body 21 made of aluminum die cast and a plurality of fixing screws 31 (only one fixing screw 31 is shown in FIG. The screw is not shown.) On one surface of the back plate portion 22 of the fixture 20, a plurality of pairs of press contact leg pieces 23 are projected in a row independently of each other. Each of the pressure contact leg pieces 23 can be expanded and pressed against the opposing wall surfaces 13 and 14 of the locking groove 12. Further, projecting edge portions 24 and 25 that mesh with the fixing screw 31 are formed in parallel with the back plate portion 22 on the inner surface side of each pressure contact leg piece 23. Furthermore, a locking protrusion 27 that fits with the locking groove 12 provided at the deepest portion of the locking groove 12 of the support member 11 is parallel to the back plate portion 22 at the outer peripheral edge of each pressure contact leg piece. Is formed.

  The back plate portion 22 has a plurality of screw holes 26 penetrating in a row along the longitudinal direction. These screw holes 26 are provided so as to correspond to the protruding positions of the plurality of pairs of press contact leg pieces 23 and to be positioned at the center of the press contact leg pieces 23. In the illustrated example, one screw hole 26 is provided for the pair of press contact leg pieces 23, but the present invention is not limited thereto, and a plurality of screw holes 26 may be formed for the pair of press contact leg pieces 23.

  In the illustrated example, the back plate portion 22 of the fixture main body 21 is formed in a strip shape when viewed from the front so as to be fitted into the locking groove 12 of the support member 11, but is not limited thereto. If a plurality of pairs of pressure contact leg pieces 23 can be inserted into the locking groove 12 of the support member 11 and can be pressed against the opposing wall surfaces 13 and 14 of the locking groove 12, they float from the locking groove 12. In that case, it may be an arbitrary shape considering the design, such as an ellipse or a triangle.

  Further, the fixture main body 21 may be other than aluminum die-cast. In short, the press-contact leg piece 23 can be expanded, and sufficient friction is generated between the opposing wall surfaces 13 and 14 of the locking groove 12 of the support member 11. Any other metal or synthetic resin may be used as long as it is a material that can induce force and can mesh with the fixing screw 31.

  The fixing screw 31 is screwed into the screw hole 26 of the fixture main body 21 and meshes with the projecting edge portions 24 and 25 of the press contact leg piece 23 at the time of screwing. It is for making it press-contact to the 12 opposing wall surfaces 13 and 14. FIG.

  The number of the fixing screws 31 may be the same as the number of the screw holes 26 of the fixing device main body 21, and if the fixing device main body 21 can be reliably fixed in the locking groove 12 of the support member 11, It may be less than that.

  When the fixing screw 31 is screwed into the screw hole 26 of the fixture main body 21, the fixing screw 31 can surely engage with the projecting edge portions 24 and 25 of the press contact leg piece 23 and can expand the press contact leg piece 23. It is the length that can be. Further, as the fixing screw 31, a female screw is preferably employed so that the fixing screw 31 can be recessed in the screw hole 26 of the fixture main body 21. Further, the material of the fixing screw 31 is preferably one that does not allow reverse rotation when the meshing with the projecting edge portions 24 and 25 of the pressure contact leg piece 23 is carried out so as not to loosen after fixing.

  Next, a procedure for fixing the fixing tool 20 to the support member 11 will be described.

  First, the press-contact leg piece 23 of the fixture main body 21 is inserted into the locking groove 12 of the support member 11, and the locking groove 12 positioned at the deepest portion of the locking groove 12 and the locking protrusion of the fixing device main body 21 are inserted. 25 is engaged. As a result, the fixture main body 21 can slide in the locking groove 12 while being guided by the locking groove 12.

  Subsequently, the fixture main body 21 is slid in the locking groove 12 and is held at a fixed fixing position with one hand, and the fixing screw 31 is screwed into an arbitrary screw hole 26 in this state. Then, the tip end portion of the fixing screw 31 comes into contact with the protruding edge portion 24 of the press contact leg piece 23 corresponding to the screw hole 26, and the press contact leg piece 23 is expanded. Thereby, a pair of press contact leg pieces 23 out of a plurality of pairs are pressed against the opposing wall surface of the locking groove 12 of the support member 11 so that the fixture body 21 does not slide down in the locking groove 12 and fixed. The temporary fixing of the tool body 21 is completed.

  Next, when the fixing position of the fixing tool main body 21 is determined, the fixing screw 31 screwed in first is further screwed into the protruding edge portion of the press contact leg piece 23, and the press contact leg piece 23 is engaged with the locking groove. It is made to press-contact with 12 opposing wall surfaces. Similarly, the fixing screws 31 are screwed into the other screw holes 26, respectively, and the respective pressure contact leg pieces 23 are pressed against the opposing wall surfaces of the locking grooves 12.
