JP 2005-299953 A

  As described above, in the air conditioner stand described in Patent Document 1, the joint insertion portions 114 and 115 having a two-part structure of the joint member 110 are inserted into the horizontal frame 120 and the vertical frame 130, and the horizontal frame 120 and the vertical frame 130 are formed. It was attached to the joint member 110. For this reason, for example, when the air conditioner base is deformed by receiving a force in the left-right direction, the upper or lower wall portion of the top portion of the joint insertion portion 114 that forms the hollow shape of the horizontal frame 120 or the lower wall portion. Press. This pressing force is combined with the fact that the joint insertion portion 114 is divided into two parts and the tip is sharp, so that the force acts locally on the hollow wall portion of the horizontal frame, and the horizontal frame is deformed. Therefore, there was a problem that the stability of the air conditioner stand was easily lost.

  The present invention has been made based on such a background, and an object of the present invention is to provide an air conditioner table in which the strength of the attachment portion between the horizontal frame and the corner bracket is improved.

  An air conditioner mount according to the present invention solves such a problem, and is an air conditioner mount including a support column, a corner bracket attached to the support column, a horizontal frame and a vertical frame attached to the corner bracket. The corner bracket includes a base fixed to the support column, and a support for attaching a horizontal frame formed so as to protrude inwardly from the wall surface constituting the base, and the horizontal frame includes the support A cylindrical section having a square cross-sectional shape so as to insert the section, and the support section has a pair of opposed walls formed at a predetermined height and projecting from a wall surface constituting the base of the corner bracket, and the opposed walls Formed in a loop shape in plan view by a connecting wall that connects the leading end portions of the horizontal frame, and the dimension between the outer surfaces is the inner side of the cylindrical portion in the horizontal frame. Is substantially equal to the dimension, further its height is characterized by being substantially equal to the inner height of the cylindrical portion of the transverse frame.

  According to the air conditioner mounting table according to the present invention having such a structural feature, the support portion protruding from the wall surface constituting the base portion of the corner bracket includes a pair of opposed walls formed at a predetermined interval and the opposed wall. The connecting wall that connects the tip portions is formed in a loop shape in plan view, and the dimension between the outer surfaces of the tip part is formed substantially the same as the width dimension inside the cylindrical part. Therefore, when the air conditioner base is deformed by receiving a force in the left-right direction, the area in contact with the wall portion constituting the cylindrical portion of the horizontal frame is larger than that of the conventional one, so that the local force concentration is reduced. This can be mitigated, and the deformation of the horizontal frame can be suppressed, and the stability of the air conditioner stand can be improved.

  The horizontal frame has a groove in the longitudinal direction at the upper part of the cylindrical portion so that a screw portion of a bolt for attaching a base frame for fixing an air conditioner projects upward. You may be allowed to. According to such a structure, the cylindrical part which inserts a support part can be made into a simple cylindrical structure, and the dimension of the front-back direction of a cylindrical part can be enlarged. As a result, it is possible to increase the area of the tip portion of the support portion that comes into contact with the upper and lower wall portions of the cylindrical portion, so that local force concentration can be easily suppressed. Moreover, since the groove part for base frame attachment is formed in the upper part of a cylindrical part, attachment of a base frame can also be made easy.

  In this case, the horizontal frame may be fixed by a fastening member in which a wall portion forming a cylindrical portion and the support portion are fastened in the horizontal direction. As described above, since the cylindrical portion into which the support portion is inserted has a simple cylindrical structure, the horizontal frame is fixed to the support portion by the fastening member that is fastened in the horizontal direction. Moreover, by fixing in this way, concentration of the force which acts on the wall part of the cylindrical part of a horizontal frame can be eased further.

  It is preferable that a spacer that fills a space between the opposing walls around the fastening member is disposed on the support portion. According to such a configuration, since the horizontal frame is fastened and fixed to the support portion in a state where the inside of the support portion formed in a loop shape is filled with the spacer, the support portion and the horizontal frame are attached when the horizontal frame is attached. Is prevented from being deformed. As a result, the horizontal frame and the corner bracket are firmly connected.

  In addition, the support portion is formed with a groove portion for screwing the tapping screw in the vertical direction so as to protrude from the surface of the connecting wall, and the wall portion forming the lower surface of the tubular portion of the horizontal frame is provided for the tapping screw. It is preferable that a through hole is formed, and the wall portion forming the lower surface of the cylindrical portion and the support portion are fixed by a tapping screw. According to such a configuration, the force transmitted from the distal end portion of the support portion to the wall portion of the cylindrical portion is reduced by the fixing with the tapping screw, and therefore the deformation of the cylindrical portion is reduced.

  The cylindrical portion of the horizontal frame has drain holes formed on the left and right sides of the through holes for tapping screws in the wall portion forming the lower surface. According to such a configuration, the moisture that has entered the loop-shaped support portion and the moisture that has entered the outside of the loop-shaped support portion can be discharged without hindrance in the horizontal frame.

  The spacer has an engaging protrusion formed on the surface of a substantially central portion when viewed from the front, and an engaging hole that engages with the engaging protrusion is formed in the opposing wall of the support portion. Preferably it is. If comprised in this way, a spacer can be easily inserted in a predetermined position in the support part currently formed in loop shape.

  Further, the column is formed in a cylindrical shape, and the corner bracket is formed with an annular wall portion having a predetermined height that allows the column to be slidably inserted as the base portion, and from the wall surface constituting the annular wall portion. It has a support part for attaching the vertical frame formed so that it may protrude inward, and it can comprise so that the said vertical frame may be fixed to this support part. If comprised in this way, while the base part which consists of an annular wall part can be attached to a suitable height position with respect to a support | pillar, since the support part which attaches a horizontal frame and a vertical frame to this base part is comprised, a horizontal frame In addition, the vertical frame can be easily connected to an appropriate position of the support column.

  Further, the support portion for fixing the horizontal frame has a dimension in which the outer wall surface of the support portion corresponds to the thickness of the side wall of the tubular portion of the horizontal frame from the front and rear outer surfaces of the corner bracket and the corner portion of the corner bracket. The lateral frame is positioned on the inner side by a dimension substantially equal to a dimension obtained by adding a dimension corresponding to R, and the inner surface of the side wall of the cylindrical portion abuts on the outer wall surface of the support portion, and the end surface of the side wall Is preferably attached so as to be in contact with the outer peripheral wall surface of the corner bracket. When configured in this way, in the corner bracket, the force acting on the corner bracket via the lateral frame acts on the thick portion of the wall portion orthogonal to the wall portion forming the support portion that fixes the lateral frame. A horizontal frame is supported. Thereby, the force which the front-end | tip part of this support part presses the upper and lower wall part of the cylindrical part of a horizontal frame is reduced. Further, since the force acting on the wall portion forming the support portion that fixes the horizontal frame via the horizontal frame is reduced, the deformation of the wall portion is reduced. As a result of this action, the strength of the air conditioner mount is improved.

  Further, in the support portion for fixing the vertical frame, the outer wall surface of the support portion adds the thickness of the side wall of the vertical frame from the left and right outer surfaces of the corner bracket and the dimension of approximately R of the corner portion of the corner bracket. The vertical frame is mounted so that the inner surface of the side wall abuts on the outer wall surface of the supporting portion and the end surface of the side wall abuts on the outer peripheral wall surface of the corner bracket. It is preferable to do. When configured in this manner, in the corner bracket, the force acting on the corner bracket via the vertical frame acts on the thick part of the wall portion orthogonal to the wall portion forming the support portion that fixes the vertical frame. A vertical frame is supported. As a result, the force acting on the wall portion forming the support portion for fixing the vertical frame via the vertical frame is reduced, so that the deformation of the wall portion is reduced and the strength of the air conditioner mounting base is improved.

  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 mounting base of the present invention, the support portion protruding from the wall surface constituting the base portion of the corner bracket is flat by a pair of opposed walls formed at a predetermined interval and a connecting wall that connects the distal end portions of the opposed walls. It is formed in a visual loop shape, and the dimension between the outer surfaces of the tip part is formed substantially the same as the inner width dimension of the cylindrical part. Therefore, when the air conditioner base is deformed by receiving a force in the left-right direction, the area in contact with the wall portion constituting the cylindrical portion of the horizontal frame is larger than that of the conventional one, so that the local force concentration is reduced. This can be mitigated, and the deformation of the horizontal frame can be suppressed, and the stability of the air conditioner stand can be improved.

  Further, the base frame 60 is formed symmetrically and symmetrically in the front-rear direction. Therefore, the left and right base frames 60 can be the same. The base frame 60 uses a mold made of aluminum or aluminum alloy whose longitudinal direction (front-rear direction) is the extrusion direction and whose basic shape is the same cross-sectional shape in the extrusion direction. The holes 63b and the like are pressed after extrusion molding.

  As shown in FIG. 3, the adjuster 70 has a rectangular horizontal wall portion 72 placed on the installation surface, and one end side (front side in FIG. 3) of two opposite sides of the horizontal wall portion 72. And a pair of opposing vertical wall portions 73 raised so as to sandwich the column 10 as an attachment member. The dimension in the front-rear direction of the upper end of the vertical wall part 73 is formed substantially the same as the dimension in the front-rear direction of the support column 10, and the dimension in the front-rear direction of the horizontal wall part 72 is formed larger than that. The horizontal wall portion 72 is formed with a bolt long hole 72a for passing an anchor bolt (not shown) at a position on the side of the support column 10, and a plurality of ribs 74 in the front-rear direction are formed on the lower surface.

Further, the end surface 73b on the bolt long hole 72a side in the vertical wall portion 73 is skewed so that the lower end position reaches substantially the center line of the bolt long hole 72a.

  Further, the adjuster 70 configured as described above sandwiches the lower end portion of the column 10 between a pair of opposed vertical wall portions 73 so that the bolt long hole 72a is inside the column 10 in the front-rear direction. Then, the cross-shaped hexagon bolt 71 is moved from the vertical wall 73 on the outer side in the left-right direction through the washer 71a, the bolt long hole 73a, the bolt insertion hole 18 of the column 10, and the through holes 19a, 19b of the column spacer 19. The nut 71c is fastened through the washer 71b through the inside. The bolt long hole 73a is for adjusting the effective height of the column 10 in accordance with the height change of the installation surface of the adjuster 70 by adjusting the penetrating position of the cross hole hexagon bolt 71.

  The adjuster 70 having the above configuration is formed symmetrically. Therefore, the adjusters 70 attached to the four corner posts 10 can be the same. The adjuster 70 uses an aluminum or aluminum alloy mold material having the same cross-sectional shape in the extrusion direction as the longitudinal direction (front-rear direction). 73b is pressed after extrusion molding.

  In the above configuration, a cap 80, which is a resin molded product for covering the upper end surface of the support column 10, is attached to the upper portion of the support column 10, as shown in FIG. The cap 80 includes a fitting portion 81 that is fitted into the support column 10, and a top wall portion 82 that covers the end surface of the support column 10. The insertion portion 81 is formed with a plurality of cuts 81a so as to be elastically reduced and inserted into the support column 10 and to be elastically engaged and held.

The air conditioner stand configured as described above is assembled as follows.
First, the supporting member 10 having the above-described configuration, the corner bracket 20, the horizontal frame 40, the vertical frame 50, the base frame 60, the adjuster 70, and other fastening members such as bolts are prepared so as to match the size of the air conditioner. Then, make a support assembly and horizontal frame assembly.

  The support assembly is a product in which an adjuster 70 is attached to the lower end of the support 10. In this case, the right front strut assembly product and the left rear strut assembly product are simply used in different directions, and the product itself is the same. Similarly, the left front support assembly and the right rear support assembly may be used in different directions, and the product itself is the same. As shown in FIG. 1, the column 10 is a positioning screw hole (in this embodiment, a tapping for positioning the corner bracket 20 in the wall portion 11 that forms the left and right outer surfaces when assembled as an air conditioner stand. A pilot hole 11a) for the screw 17 is present, and an arcuate wall 13 is disposed at the corners of the four corners.

  Moreover, as shown in FIG. 3, the column assembly 19 has a column spacer 19 inserted into the lower end of the column 10 and the adjuster 70 faces inward in the front-rear direction as shown in FIG. The lower end portion of the column 10 is inserted between the pair of opposing vertical wall portions 73 so as to be. And the hex bolt 71 with a cross hole is inserted from the vertical wall part 73 which becomes the left-right direction outer side through the washer 71a, the bolt long hole 73a, the bolt insertion hole 18 of the support | pillar 10, and the through-hole 19a or 19b of the support | pillar spacer 19. Then, it is temporarily assembled by fastening the nut 71c (see FIG. 1). If the temporarily assembled product is shipped at the manufacturer shipping stage, the number of work steps at the site can be reduced.

  On the other hand, the horizontal frame combination product is obtained by attaching the corner brackets 20 to the left and right of the horizontal frame 40. In this case, since the horizontal frame 40 is configured symmetrically as described above, the front and rear horizontal frames 40 are the same. Further, since the corner bracket 20 is also formed symmetrically in the height direction, the corner bracket 20 attached to the pillars 10 at the four corners is the same. Therefore, the front and rear horizontal frame combination products may be the same, and may be reversed left and right when assembling as an air conditioner stand. As for this horizontal frame assembly product, if the assembled product is shipped, the number of work steps in the field can be reduced.

  When the corner brackets 20 are attached to the left and right sides of the horizontal frame 40, the support portions 31 of the corner bracket 20 are inserted into the end portions of the horizontal frame 40 as shown in FIG. At this time, by inserting the left and right corner brackets 20 upside down, the fastening pieces 28 of the two corner brackets 20 can be inserted in the front and rear direction in the assembled air conditioner stand. In this assembly, the height dimension and the outer surface dimension of the support part 31 are formed so as to substantially coincide with the inner height dimension and the front-rear direction dimension of the tubular part 41 of the horizontal frame 40. Further, when the support portion 31 is inserted, the spacer 36 is inserted, and the rivet 44 is inserted, the through holes 37 and 38 are aligned with the rivet hole 45, and riveted. Further, the tapping screw 47 is inserted into the support portion 31 inserted at the end of the horizontal frame 40 from the lower through hole 48 for the tapping screw 47, and the tapping screw 47 is screwed into the groove portion 35 for screwing the tapping screw. Finally fix.

  Next, the four-column support assembly assembled as described above is prepared, and the horizontal frame assembly is attached to the support assembly. In this attachment, first, the attachment height position of the horizontal frame assembly is set, and the pilot hole 11a for the positioning tapping screw 17 is selected. Then, the annular wall portion 20A that forms the base of the corner bracket 20 attached to the horizontal frame 40 is inserted from the top of the column 10, and the tapping screw 17 is screwed into the selected lower hole 11a via the through hole 21a. Temporarily fix the frame assembly to a predetermined height position. Next, in a state where the inner surface of the side wall 52 of the vertical frame 50 is in contact with the fastening piece 28 of the corner bracket 20 attached to the front and rear struts 10, the bolts 29 are attached to the bolt holes 52a and 28a via the washers 29a. Insert the nut 29c from the inside of the vertical frame 50 through the washer 29b. As a result, the slit interval of the fastening piece 28 is narrowed, the annular wall portion 20A of the corner bracket 20 is fastened, the horizontal frame assembly is fixed to the support column 10, and the vertical frame 50 is further supported by the fastening piece 28 as a support portion. It is attached.

  Further, after the horizontal frame 40 and the vertical frame 50 are attached to the predetermined height position of the support assembly, the base frame 60 is attached between the front and rear horizontal frames 40. The left and right positions of the base frame 60 are adjusted according to the mounting position of the vibration isolator rubber of the air conditioner. This adjustment can be made by sliding and changing the position of the bolt 61 attached in the groove 42 of the lateral frame 40. Further, the position of the anti-vibration rubber 64 attached to the slit 65 of the base frame 60 in the front-rear direction can also be adjusted at the slit 65.

  In the final stage, the air conditioner stand assembled as described above corresponds to the situation of the installation surface by adjusting the position in the height direction of the hexagon bolt 71 with a cross hole passing through the bolt long hole 73a in the adjuster 70. To adjust the effective height direction of the column 10.

According to the air conditioner base according to the present embodiment configured as described above, the following effects can be obtained.
(1) The support portion 31 protruding from the wall surface constituting the base portion of the corner bracket 20 is a loop in plan view by a pair of opposing walls 32 formed at a predetermined interval and a connecting wall 33 that connects the distal ends of the opposing walls 32. In addition, the outer surface dimension of the tip portion is formed substantially the same as the inner width dimension of the tubular portion 41. Therefore, when the air conditioner mounting base is deformed to the left and right (L or R direction) by receiving the force in the left and right direction as shown in FIG. 8A, it contacts the wall portion constituting the cylindrical portion 41 of the horizontal frame 40. The area is getting bigger. FIG. 8B is an example of a corner bracket when the connecting wall 33 is not present, and is basically equivalent to the conventional product, but in this case, the upper and lower wall portions of the cylindrical portion 41 are arranged. The contact area is reduced. For this reason, the force which presses the upper and lower wall parts of the cylindrical part 41 from the front-end | tip part of the opposing wall 32 concentrates locally, and becomes a big force (F1). For this reason, the upper and lower wall portions of the cylindrical portion 41 are easily deformed, and the air conditioner mounting table is easily deformed. On the other hand, by providing the connection wall 33 as shown in FIG. 8C, the area that contacts the upper and lower wall portions of the tubular portion 41 is increased. For this reason, the force which presses the upper and lower wall parts of the cylindrical part 41 from the front-end | tip part of the support part 31 is disperse | distributed, and becomes a small force (F2). As a result, the concentration of local forces can be alleviated, the deformation of the horizontal frame 40 can be suppressed, and the stability of the air conditioner table can be improved.

  (2) Since the horizontal frame 40 is formed with a cylindrical portion 41 at the lower portion and a groove portion 42 for accommodating the head portion 61b of the base frame mounting bolt 61 is formed at the upper portion thereof, the cylinder into which the support portion 31 is inserted. The cylindrical portion 41 can have a simple cylindrical structure, and the longitudinal dimension of the cylindrical portion 41 can be increased. As a result, the area of the front end portion of the support portion 31 that contacts the upper and lower wall portions of the cylindrical portion 41 can be increased, and local force concentration can be easily suppressed. In addition, since the groove portion 42 for attaching the base frame is formed in the upper portion of the tubular portion 41, the attachment of the base frame 60 can be facilitated.

  (3) Since the cylindrical portion 41 into which the support portion 31 is inserted has a simple cylindrical structure, the horizontal frame 40 is supported by the fastening member (in this case, the rivet 44) fastened in the horizontal direction. It can be fixed to the part 31. Further, by fixing in this way, the concentration of force acting on the wall portion of the tubular portion 41 of the horizontal frame 40 can be further reduced.

  (4) The tapping screw 47 is screwed into the groove portion 35 for screwing the tapping screw in the vertical direction formed on the connecting wall 33 of the support portion 31 from the lower wall portion 46 of the tubular portion 41 of the horizontal frame 40, Since the wall portion 46 forming the lower surface of the tubular portion 41 and the support portion 31 are fixed by the tapping screw, the force transmitted from the tip portion of the support portion 31 to the wall portion of the tubular portion 41 is reduced. Therefore, the deformation of the tubular portion 41 is alleviated.

  (5) Since the water drain holes 49 are formed on the left and right sides of the through hole 48 for the tapping screw 47 in the wall portion 46 forming the lower surface of the cylindrical portion 41 of the horizontal frame 40, a loop is formed in the horizontal frame 40. The moisture that has entered the support portion 31 having a shape and the moisture that has entered the outside of the support portion having a loop shape can be discharged without hindrance.

  (6) Since the horizontal frame 40 is fastened and fixed to the support portion 31 in a state where the spacer 36 is inserted into the support portion 31 formed in a loop shape, The deformation of the horizontal frame 40 is suppressed. As a result, the horizontal frame 40 and the corner bracket 20 are firmly connected.

  (7) In addition, an engagement protrusion 39 is formed on the surface of the substantially central portion viewed from the front of the spacer 36, and an engagement hole 32 a that engages with the engagement protrusion 39 is formed in the opposing wall 32 of the support portion 31. Therefore, the spacer 36 can be easily inserted into a predetermined position in the support portion 31 formed in a loop shape.

  (8) The corner bracket 20 has an annular wall portion 20A that is slidably inserted into the cylindrical column 10 as a base portion, and a support portion that attaches the horizontal frame 40 and the vertical frame 50 so as to protrude from the base portion. Since it is formed, the horizontal frame 40 and the vertical frame 50 can be easily connected to the support column 10 at an appropriate height position.

  (9) The support portion 31 that fixes the horizontal frame 40 has an outer wall surface of a dimension y2 that corresponds to the thickness of the side wall of the horizontal frame 40 from the front and rear outer surfaces of the corner bracket 20 and a corner portion R of the corner bracket 20. It is formed to be located on the inner side by a dimension y1 that is substantially equal to the dimension obtained by adding the corresponding dimension y3. 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 which the distal end portion of the support portion 31 presses the upper and lower wall portions of the tubular portion 41 of the horizontal frame 40 is reduced. Further, since the force acting on the wall portion 24 forming the support portion 31 that fixes the horizontal frame 40 via the horizontal frame 40 is reduced, the force on the wall portion 24 forming the support portion 31 in the corner bracket 20 is reduced. , Its deformation is reduced. As a result of this action, the strength of the air conditioner mount is improved.

  Further, the fastening piece 28 as a support part for fixing the vertical frame 50 has a dimension x2 corresponding to the thickness of the side wall 52 of the vertical frame 50 from the left and right 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 x1 that is substantially equal to a dimension obtained by adding a dimension x3 corresponding to the corner R. The vertical frame 50 is attached so that the inner surface of the side wall 52 abuts on the outer surface of the fastening piece 28 and the end surface of the side wall 52 abuts on the outer peripheral wall surface of the annular wall portion 20A of the corner bracket 20. . 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 portion 25 forming the fastening piece 28 in the corner bracket 20 is reduced, the deformation thereof is reduced, and the strength of the air conditioner mount is improved.

The support column 10, the corner bracket 20, the horizontal frame 40, and the vertical frame 50 are formed from an extruded mold material made of aluminum or aluminum alloy, and are formed so that the basic shape has the same cross-sectional shape in the extrusion direction. Cost reduction and weight reduction can be achieved, and appearance can be improved.
