  However, in the above-described male screw anchor system, as shown in FIG. 6B, the male screw 800 protrudes toward the angle member 200 side, so that the slide bolt is attached after the angle member 200 is attached to the outer wall surface G. 900 cannot be attached to the angle member 200. That is, before attaching the angle member 200 to the outer wall surface G, it is necessary to attach the sliding bolt 900 to the angle member 200. However, the sliding bolt 900 is not shown in FIG.

  Further, in the case of the female screw anchor system, as shown in FIG. 6A, the slide bolt 900 can be attached to the angle member 200 after the angle member 200 is attached to the outer wall surface G. However, the sliding bolt 900 must be inserted and slid from the end of the angle member 200 to be installed at a predetermined position. If the end portion of the angle member 200 attached to the outer wall surface G is blocked by another housing facility such as a rain gutter, the sliding bolt 900 cannot be attached to the angle member 200. It is necessary to attach the sliding bolt 900 to the angle member 200 before attaching to the outer wall surface G.

  The present invention was devised in view of the above circumstances, and a sliding bolt that can securely attach a sliding bolt to an angle member even if the angle member is first attached to a wall surface such as an outer wall surface, It aims at providing the installation stand for the used outdoor unit.

  The sliding bolt according to the present invention is a sliding bolt that is slidably fitted into an angle member having a substantially C-shaped cross section fixed to a wall surface or the like, and can be fitted inward from the opening groove of the angle member. It has a main body part and a bolt part erected on the main body part, the main body part has a substantially parallelogram shape, and the height dimension in a state where the short opposite side of the opposite sides is the bottom side is The obtuse angle part of the substantially parallelogram is set to be slightly smaller than the inner width dimension of the angle member, and a leaf spring part protruding outward is formed, and the dimension between the diagonal leaf spring parts is applied by an external force.

  A sliding bolt 100 according to an embodiment of the present invention is a sliding bolt that is slidably fitted into an angle member 200 having a substantially C-shaped cross section fixed to an outer wall surface, and an opening groove 210 of the angle member 200. A main body part 110 that can be fitted inwardly, and a bolt part 120 erected on the main body part 110. The main body part 110 has a substantially parallelogram shape, and is short of the opposite sides. The height dimension H1 (see FIG. 3A) with the opposite side 111S as the base is set slightly smaller than the inner width dimension W (see FIG. 4A) of the angle member 200, and is substantially parallelogram-shaped. The obtuse angle portion is formed with a leaf spring portion 113 protruding outward, and the dimension H2 (see FIG. 3 (A)) between the diagonal leaf spring portions 113 is the inner side when no external force is applied. Width Greater than W, it is in a bent state the leaf spring portion 113 inwardly is smaller than the inner width W.

Prior to the description of the sliding bolt 100 according to the embodiment of the present invention, the angle member 200 to which the sliding bolt 100 is attached will be described.
The angle member 200 is the same as that used in a conventional outdoor unit mounting base, and as shown in FIGS. 5 and 6, a bottom surface portion that is a surface facing one surface where the opening groove 210 is formed. 220 is formed in a substantially C-shaped cross section that is flat. The reason why the bottom surface portion 220 of the angle member 200 is flat is that the bottom surface portion 220 is in contact with the outer wall surface.
Further, the front edge portion 230 is extended from the upper edge and the lower edge of the opening groove 210, so that the angle member 200 has a substantially C-shaped cross section.

In addition, the angle member 200 has a plurality of long holes 221 formed at equal intervals in the bottom surface portion 220. The angle member 200 is attached to the outer wall surface using the long hole 221. Note that the angle member 200 may be attached to the outer wall surface by either the male screw anchor method or the female screw anchor method.
In addition, as shown in FIG. 4A, the inner side width dimension W of the angle member 200 is a side surface that is two surfaces other than the surface on which the bottom surface portion 220 that is in contact with the outer wall surface and the opening groove 210 are formed. The dimension between the parts 240 shall be pointed out.

The angle member 200 constitutes a part of a stationary table 1000 for attaching an outdoor unit of an air conditioner to an outer wall surface. The stationary table 1000 includes two angle members 200 attached to the outer wall surface of the house in parallel in two upper and lower stages, four slide bolts 100 attached to the two angle members 200, and the slide bolt 100. Two connecting rods 300 that connect the two angle members 200 and two arms 400 that are connected and attached to the connecting rod 300 in a state of projecting substantially at right angles to the outer wall surface. doing.

The slide bolt 100 according to the embodiment of the present invention used for the mounting base 1000 is composed of the main body 110 and the bolt 120 that is erected on the main body 110 as described above.
The main body 110 is formed by bending a steel plate, and includes a substantially parallelogram central piece 111 and two kinds of four bent pieces 112 bent in an orthogonal direction from each side of the central piece 111. Are integrally formed.

  A through hole 111 </ b> A through which a shaft part 121 of a bolt part 120 described later passes is formed in the central part of the central piece 111, that is, the central part of the main body part 110. In addition, three recesses 111B are formed around the through hole 111A at intervals of 120 degrees. Since the concave portion 111B is formed, three convex portions 111C are formed around the through hole 111A on the back surface side of the central piece 111. The convex portion 111 </ b> C exerts a function to prevent the bolt portion 120 from rotating freely by contacting the outer periphery of the hexagonal head portion 123 (see FIG. 5) of the bolt portion 120.

The bent piece 112 includes a long bent piece 112A bent from the long opposite side 111L of the central piece 111 and a short bent piece 112B bent from the short opposite side 111S.
The long folded piece 111A is set to be narrower than the short folded piece 111B.
The width of the short bent piece 112B is such that when the sliding bolt 100 is fitted into the angle member 200, the short bent piece 112B is on the bottom surface portion 220 of the angle member 200, and the central piece 111 is the front edge portion 230 of the angle member 200. It is set so that each may contact the back of each. On the other hand, the long folded piece 112 </ b> A is set so as not to contact the bottom surface portion 220 of the angle member 200. This is to prevent the sliding of the sliding bolt 100 within the angle member 200 from being obstructed by contacting the bottom portion 220 not only the short bent piece 111B but also the long bent piece 112A.

  A plate spring 113 is provided at each of the pair of obtuse angle portions of the main body 110. The leaf spring 113 is extended from the long bent piece 111L, and a tip portion 113A of the leaf spring 113 protrudes slightly outward from the short bent piece 112B.

  Further, the main body 110 has a height dimension H1 in a state where the short opposite side 111S of the opposite sides is the base (the state shown in FIG. 3A) is set slightly smaller than the inner width dimension W of the angle member 200. ing. Further, the dimension H2 between the pair of leaf spring portions 113 is larger than the inner width dimension W when no external force is applied, and is larger than the inner width dimension W when the leaf spring portion 113 is bent inward. Get smaller.

The bolt part 120 is attached to the main body part 110 configured as described above to form the sliding bolt 100. As for the bolt part 120, the shaft part 121 is inserted into the through hole 111B of the main body part 110 from the back side, and the head part 123 of the bolt part 120 is brought into contact with the convex part 111C. The bolt part 120 is fixed to the main body part 110 by further screwing the nut part 122 with the shaft part 121 inserted in the main body part 110.
Thus, the slide type bolt 100 in which the bolt part 120 is erected on the main body part 110 is obtained.
The bolt part 120 may be fixed to the main body part 110 by a fixing method other than the fixing by the nut part 122, such as welding.

  Next, a procedure for attaching the sliding bolt 100 to the angle member 200 will be described. It is assumed that the angle member 200 is attached to the outer wall surface in advance with the opening groove 210 on the front side. The angle member 200 is attached by the male screw anchor method in FIG. 4, but there is no particular problem even if it is attached by the female screw anchor method.

As shown in FIG. 4A, the sliding bolt 100 is fitted inward from the front side through the opening groove 210 of the angle member 200. At this time, the long opposite side 111 </ b> L is the bottom surface, and the shaft part 121 of the bolt part 120 is protruded from the opening groove 210.
The sliding bolt 100 in this state can be freely slid inside the angle member 200.

  As shown in FIG. 4 (B), the leaf spring portion 113 of the obtuse angle portion is rotated while contacting the inner side surface of the side surface portion 240 of the angle member 200. At the time of this rotation, the leaf spring portion 113 is given an external force from the angle member 200 and bends inward, so that a resistance is generated in the rotation but is not hindered. This is because the leaf spring portion 113 is extended from the long bent piece 112A of the long opposite side 111L, and the tip of the leaf spring portion 113 is located on the short bent piece 112B side.

As shown in FIG. 4C, the sliding bolt 100 that has finished rotating is in a state where the short opposite side 111S is the bottom side. Since the height dimension H1 of the sliding bolt 100 in a state where the short opposite side 111S is the bottom side is set to be slightly smaller than the inner width dimension W of the angle member 200, the sliding bolt 100 in this state has a main body portion. Since the obtuse angle part 110 is caught by the front edge part 230 extended from the upper edge and lower edge of the opening groove | channel 210 of the angle material 200, it cannot remove from the near side of the opening groove | channel 210 of the angle material 200. Moreover, the sliding bolt 100 in this state can be freely slid inside the angle member 200.

To remove the sliding bolt 100 in this state, the sliding bolt 100 is rotated so that the long opposite side 111L becomes the bottom surface. That is, the state shown in FIG. However, this rotation does not go smoothly because the leaf spring portion 113 is in the obtuse angle portion. This is because the leaf spring portion 113 is extended from the long bent piece 112A of the long opposite side 111L, and the tip end portion 113A of the plate spring portion 113 is located on the short bent piece 112B side. That is, when the sliding bolt 100 is to be rotated, the tip end portion 113A of the leaf spring portion 113 bites into the inner side surface of the side surface portion 240 of the angle member 200 and is difficult to rotate.
However, if a force of a certain level or more is applied, the leaf spring portion 113 bends inward, and the dimension H2 between the leaf spring portions 113 becomes smaller than the inner width dimension W. Therefore, the sliding bolt 100 can be rotated. become able to.

Next, the outdoor unit mounting base 1000 using the above-described sliding bolt 100 will be described with reference to FIG.
The outdoor unit mounting base 1000 includes an angle member 200 having a substantially C-shaped cross-sectional view that is fixed to an outer wall surface, a slide bolt 100 that is slidably fitted into the angle member 200, and the slide bolt 100. A connecting rod 300 attached to the angle member 200, and an arm 400 attached to the connecting rod 300 and projecting in a substantially orthogonal direction with respect to the outer wall surface.

  The angle member 200 in the outdoor unit mounting base 1000 is attached to the outer wall surface in parallel in two upper and lower stages. The angle member 200 is the same as that described above, and thus detailed description thereof is omitted.

  As shown in FIG. 5, the connecting rod 300 is a portion to which the angle member 200 that is parallel in two upper and lower stages is connected and the arm 400 is attached. The connecting rod 300 has a shape in which one surface of the quadrangular prism is open, and two surfaces corresponding to the shaft portion 121 of the bolt portion 120 of the sliding bolt 100 are provided on the surface 310 facing the open surface. The heel side opening 311 is opened. In addition, arm attachment holes 321 for attaching the arm 400 are formed on both side surfaces 320.

  As shown in FIG. 5, the arm 400 is formed by bending a single steel plate. The upper surface 410 is flat, and a triangular side surface 420 that is substantially long in side view extends from the upper surface 410. Yes. Two long holes 411 are formed in the upper surface 410. The long hole 411 is a portion for fixing the insulating rubber 430 interposed between the outdoor unit to be installed. Further, two arm side openings 421 corresponding to the arm mounting holes 321 of the connecting rod 300 are formed on the base end side of the side surface 420. A protective cap 440 made of a soft material is attached to the tip of the arm 400.

A procedure for assembling the mounting table 1000 for the outdoor unit composed of the above-described parts will be described.
Two angle members 200 are attached to the outer wall portion in parallel in two upper and lower stages. Two sliding bolts 100 are attached to one angle member 200 by the procedure described above. The mounting position of these sliding bolts 100 is determined according to the position of the arm 400 that should support the outdoor unit.

The shaft portion 121 of the bolt portion 120 of the sliding bolt 100 attached to the upper and lower two-stage angle members 200 is inserted into the connecting rod side opening 311 of the connecting rod 300 and fixed with the nut 150. Thus, the two connecting rods 300 are attached in a state in which the upper and lower two-stage angle members 200 are connected.
The arm attachment hole 311 on the base end side of the connecting rod 300 and the arm side opening 421 of the arm 400 are aligned, and the arm 400 is attached to the connecting rod 300 with a bolt 450 and a nut 451.

In the above-described embodiment, the sliding bolt 100 is described as being used for the outdoor unit mounting base 1000 , but it is needless to say that the present invention is not limited to this.

  In addition, since the mounting base 1000 for the outdoor unit is attached to the outer wall surface, the angle member 200 is also attached to the outer wall surface. Needless to say, the material 200 is attached to the inner wall surface.
