JP 2005-299953 A

  As described above, in the air conditioner stand described in Patent Document 1, the joint member (corner bracket) 110 for connecting the horizontal frame 120 and the vertical frame 130 to the support column 100 is a hexagon socket head cap screw with respect to the fixing surface 105 of the support column 100. The structure is fixed by 108. For this reason, the surroundings of the bolt insertion hole 108b of the support column 100 and the bolt insertion hole 113 of the joint member 110 may be deformed, and the air conditioner table may be easily deformed. In particular, there is a problem in strength in the case of using an extrusion mold material made of aluminum or aluminum alloy as in recent years. In addition, the nut 108a fastened to the hexagon socket head bolt 108 is inserted in a sliding manner while being held by the holder body 107, and the bolt 108 must be tightened from the inside of the corner portion of the air conditioner stand, so that assembly work Was troublesome. In addition, the structure for fixing the joint member 110 and the structure for attaching the horizontal frame 120 and the vertical frame 130 are complicated, which causes a cost increase. Further, the horizontal frame 120 and the vertical frame 130 have a structure in which the joint insertion portions 114 and 115 are inserted into the respective end portions, and at this time, the locking piece portions 124 and 131 are engaged with the engagement portions 116 and 117. For this reason, it has been difficult to avoid rattling due to the clearance around the joint insertion portions 114 and 115.

  The present invention has been made based on such a background, and an object of the present invention is to provide an air conditioner stand that improves the strength of the mounting portion of the corner bracket, improves the assembly workability, and reduces the cost.

  The air conditioner stand according to the present invention solves such problems, and includes a cylindrical column, a corner bracket that is slidably attached to the cylindrical column in the height direction, and a corner bracket. An air conditioner pedestal comprising a horizontal frame attached to a support portion projecting inwardly in the left and right directions and a vertical frame attached to a support portion projecting inwardly in the front and rear direction of the corner bracket, wherein the corner bracket slides the support column An annular wall portion having a predetermined height to be freely inserted, a slit portion in which a slit having a predetermined width is formed in the height direction in the annular wall portion, and a gap between the slits from the wall surface of the annular wall portion is maintained in the slit portion. And a pair of opposing fastening pieces projecting substantially orthogonally, and a pair of fastening pieces by a fastening member spanned between the fastening pieces Wherein the in is fixed to the tightened by the struts so as to narrow the space dimension.

  According to the air conditioner mounting table according to the present invention having such a structural feature, the corner brackets are opposed to each other in a pair of protrusions that project substantially orthogonally from the wall surface of the annular wall portion at the slit portion. The fastening pieces are fixed by fastening them so as to narrow the distance between the pair of fastening pieces. For this reason, the corner bracket is firmly attached to the cylindrical column at a predetermined height position using the frictional force and elastic force between the inner peripheral surface of the annular wall portion and the outer peripheral surface of the column. Compared to the conventional case, a large force is prevented from acting on the mounting bolt hole, and the lack of strength around the mounting bolt hole is solved. Further, since the corner bracket is attached by fastening the fastening member spanned between the fastening pieces, the workability is improved. Further, it is not necessary to form a conventional groove portion in the cylindrical support column or the outer surface portion of the corner bracket, so that the structure is simplified and the cost is reduced.

  The fastening piece may also be used as a support portion protruding inwardly in the left-right direction or a support portion protruding inwardly in the front-rear direction. In this case, it is not necessary to separately form a support part protruding inward in the left-right direction or a support part protruding in the front-rear inward direction on the side where the fastening piece of the corner bracket is formed, so that the structure is simplified. Thus, the cost can be further reduced.

  In this case, the fastening member spanned between the fastening pieces may have a structure in which a horizontal frame or a vertical frame is attached and the fastening pieces are fastened together so as to be fastened. In this case, since the fastening member for attaching the corner bracket and the fastening member for attaching the horizontal frame or the vertical frame are unified, the workability can be further improved and the cost can be reduced. it can.

  The corner bracket has a horizontal frame mounting support portion that protrudes inward in the left-right direction and the fastening piece that protrudes in the front-rear inward direction, and the fastening piece also serves as a support portion for the vertical frame mounting. The vertical frame is formed in a U-shaped cross section composed of an upper wall, a side wall, and a lower wall, and an inner surface of the side wall of the vertical frame is in contact with an outer surface of the fastening piece. May be fastened together by a fastening member for fastening the fastening piece. If comprised in this way, since the fastening member which fastens a fastening piece to the side surface of an air-conditioning stand is used, a fastening member becomes difficult to stand out. In addition, the vertical frame can be attached with the upper wall placed on the support portion, and the fastening member can be operated from the inner side surface of the vertical frame. The workability of the work and the installation work of the vertical frame can be improved.

  Further, the horizontal frame may have a cylindrical portion extending over the entire length of the left and right, and the support portion may be inserted and attached into the cylindrical portion. In this case, when the horizontal frame is attached, the attachment work can be performed in a state where one end of the horizontal frame is supported by the support portion, so that workability is good.

  Further, the support column is formed in a substantially square cylindrical cross-sectional shape, and the fastening piece has an outer wall surface of the fastening frame that extends from the left and right outer surfaces or the front and rear outer surfaces of the corner bracket to the side wall of the vertical frame or the horizontal frame. The vertical frame or the horizontal frame is positioned on the inner side of the fastening piece by a dimension approximately equal to the dimension obtained by adding the dimension corresponding to the wall thickness and the dimension corresponding to R at the corner of the corner bracket. While contacting the outer surface, the end surface of the side wall may be attached so as to contact the outer peripheral wall surface of the corner bracket. In this case, the force acting on the corner bracket via the vertical frame or the horizontal frame is supported in a state where the force acts on the thick portion of the wall portion orthogonal to the wall portion forming the fastening piece in the annular wall portion. The force on the wall portion forming the fastening piece in the corner bracket is reduced, the deformation is reduced, and the strength of the annular wall portion is improved.

  Further, in this case, the support portion has a dimension and a corner corresponding to the thickness of the side wall of the vertical frame or the horizontal frame from the left and right outer surfaces or the front and rear outer surfaces of the corner bracket. The vertical frame or the horizontal frame is positioned on the inner side by a dimension approximately equal to the dimension obtained by adding the dimension corresponding to R at the corner of the bracket. It is preferable that the end surface of the side wall of the frame or the horizontal frame is attached so as to contact the outer peripheral wall surface of the corner bracket. In this case, the force acting on the corner bracket via the vertical frame or the horizontal frame is supported in a state where the force acts on the thick portion of the wall portion orthogonal to the wall portion forming the support portion in the annular wall portion. The force with respect to the wall part which forms the support part in a corner bracket decreases, the deformation | transformation is reduced, and the intensity | strength of an annular wall part improves.

  In addition, the support column has a pilot hole for a positioning tapping screw or a screw hole for a positioning screw formed on the left and right outer surfaces at predetermined intervals in the vertical direction, and the corner bracket is positioned on the left and right outer wall portions. You may make it have a through-hole which penetrates a tapping screw for positioning or a positioning screw. If comprised in this way, the mounting height position of the corner bracket attached to the support | pillar of four corners will be changed in steps by specifying the positioning screw hole to be used, and the height placement will be made uniform easily. be able to.

  Further, instead of such a stepwise positioning configuration of the corner bracket, a positioning tapping screw pilot hole may be provided on the left and right outer wall portions of the corner bracket. If comprised in this way, the front-end | tip part of a tapping screw can be screwed with respect to the support | pillar in which the lower hole of the positioning tapping screw or the screw hole of the positioning screw is not provided by screwing a tapping screw in a corner bracket. Therefore, after positioning the corner bracket at an arbitrary position, the fastening piece can be tightened to fix the corner bracket.

  The corner bracket may be attached to a plurality of positions in the height direction with respect to the support column, and the horizontal frame and the vertical frame may be attached in a plurality of stages. In this way, when applied to a multi-stage air conditioner stand, the work of attaching the corner bracket to the middle height position of the column is as good as the case of attaching the corner bracket to the upper end of the column. Assembling workability is improved.

  In addition, a cap that covers the upper end end surface of the support column is attached to the upper end portion of the support column, and the cap is configured by an insertion portion that is inserted into the support column and a top wall portion that covers the end surface of the support column. May be. In this case, since the strut is formed as a simple cylindrical member, the structure of the fitting portion of the cap is simplified.

  Further, it is preferable that the support column, the corner bracket, the horizontal frame, and the vertical frame are formed from an extruded mold member made of aluminum or aluminum alloy, and are formed so that the basic shape has the same cross-sectional shape in the extrusion direction. . By comprising in this way, cost reduction and weight reduction can be achieved, and the appearance of appearance can be improved.

  According to the air conditioner stand according to the present invention, the corner bracket has a predetermined height with respect to the cylindrical column using the frictional force and the elastic force between the inner peripheral surface of the annular wall portion and the outer peripheral surface of the column. Since it is firmly attached to the position, it is possible to avoid a large force acting on the mounting bolt hole as compared with the conventional case, and to solve the problem of insufficient strength around the mounting bolt hole. Further, since the corner bracket is attached by fastening the fastening member spanned between the fastening pieces, the workability is improved. Further, it is not necessary to form a conventional groove portion in the cylindrical support column or the outer surface portion of the corner bracket, thereby simplifying the structure and reducing the cost.

Therefore, the force acting on the corner bracket 20 via the vertical frame 50 is supported in a state of acting on the thick portion of the wall portion 21 orthogonal to the wall portion 25 forming the fastening piece 28 in the annular wall portion 20A. The force with respect to the wall part 25 which forms the fastening piece 28 in the corner bracket 20 is reduced, the deformation is reduced, and the strength of the annular wall part 20A is improved.

  (9) Similarly to the case of the fastening piece 28, the support portion 31 has a dimension y 2 whose outer wall surface corresponds to the thickness of the side wall of the lateral frame 40 from the front and rear outer surfaces of the corner bracket 20 and the corner bracket 20. It is formed so as to be located on the inner side by a dimension y1 that is substantially equal to a dimension obtained by adding a dimension y3 corresponding to R at the corner of the. The lateral frame 40 is attached such that the inner surface of the side wall abuts on the outer surface of the support portion 31 and the end surface of the side wall of the lateral frame 40 abuts on the outer peripheral wall surface of the corner bracket 20. Therefore, since the force acting on the corner bracket 20 via the horizontal frame 40 is supported in a state of acting on the thick portion of the wall portion 22 orthogonal to the wall portion 24 forming the support portion 31 in the annular wall portion 20A, The force with respect to the wall part 24 which forms the support part 31 in the corner bracket 20 decreases, the deformation | transformation is reduced, and the intensity | strength of 20 A of annular wall parts improves.
