  The present invention relates to a roof stand of an air conditioner outdoor unit, and in particular, a rear seat plate arranged at a position on the high side of the roof, a front seat plate arranged at a position on the low side of the roof, a rear seat plate and a front seat plate, The present invention relates to a roof mount for an air conditioner outdoor unit including a pair of support members that are spanned between the two.

Conventionally, in such an outdoor unit roof mounting table, the support member is installed between a base disposed substantially horizontally for mounting the air conditioner outdoor unit, and a front end portion of the base and a front seat plate, And a stay for supporting the front end portion of the base at a predetermined height position. Further, in the conventional outdoor unit roof mounting table, a mechanism is provided for adjusting the height of the front end portion of the base so that the roof can be installed on a roof having various inclination angles. This mechanism is configured such that the front end of the base is bent downward, the stay is slidable in the height direction while covering the bent portion from the front, and the stay is bolted to the bent portion of the base at an arbitrary position ( The following is known as prior art A). Separately, the stay itself is composed of two parts, an upper stay and a lower stay, and the lower stay is slidable in the height direction while covering the upper stay from the front. A structure in which the stay is bolted to the upper stay (hereinafter referred to as Conventional Technology B) is known.

JP-A-9-236287 Japanese Patent Laid-Open No. 10-170031 JP 2001-235186 A JP 2001-355879 A JP 2006-125584 A JP 2006-145090 A

  However, in any conventional system, a long hole in the height direction is formed in the front wall of the stay or the lower stay that covers from the front, and the bent portion of the base on the covered side or the upper stay has a bolt A hole is formed, and a bolt is inserted over the long hole and the bolt hole to be fastened with a nut. For this reason, in a state where the air conditioner outdoor unit is placed on the base, a force in the axial direction acts on the bolt due to a moment due to the load of the air conditioner, and the peripheral portion of the bolt penetration part (which fixes the bolt by this force ( In this case, the hole edge of the long hole is easily deformed or damaged. As a result, there is a problem that the life of the stay or the lower stay is shortened. In addition, since the bent portion or the upper stay of the base front end is formed to a certain length, the height position of the base front end cannot be made equal to or less than the length of the bent portion of the base front end or the upper stay. For this reason, applications where the inclination angle between the position where the rear seat plate is supported and the position where the front seat plate is supported are gentle, for example, a gently inclined roof, and a gentle slope like a dog running around the building. It was difficult to use it on the ground.

  The present invention has been made in view of such a problem of the conventional product, and has a structure in which a large force does not act on the peripheral portion of the bolt penetrating portion in the stay, thereby extending the life of the stay. The object is to provide a roof stand for outdoor units. Moreover, this invention is providing the roof stand of the air-conditioner outdoor unit which can be used over a wide range from a gently inclined roof, the ground, etc. to a steep roof.

  The roof stand of the air conditioner outdoor unit according to the present invention solves the above-described problems, and includes a rear seat plate disposed on the high side of the roof, a front seat plate disposed on the lower side of the roof, and the rear seat. And a pair of support members for placing an air conditioner outdoor unit installed between the front plate and the front seat plate. In addition, the support member mounts an air conditioner outdoor unit in which a lower end is supported by the front seat plate and a rear end is supported by the rear seat plate and the front end is supported by the stay and is disposed substantially horizontally. And a connecting member attached to the front end of the base for connecting and fixing the stay and the base. Further, in the state where the connecting member is attached to the front end portion of the base, a through hole portion is formed in front of the front end portion of the base so that the stay is vertically penetrated to change the penetrating position in a sliding manner. At the same time, it can be fixed to the stay at an appropriate penetrating position.

  According to the roof stand of the air conditioner outdoor unit according to the present invention having the above-described configuration, the stay is penetrated into the through hole portion of the connecting member so as to be slidable and fixable. By setting, the height of the front end portion of the base can be adjusted to a predetermined position. Further, in this case, the moment due to the load of the air conditioner placed on the base is supported by the front and rear wall surfaces that form the through-hole portion, so that it is a case where bolting is performed as in the conventional case. However, no force acts locally around the bolt. For this reason, the deformation | transformation and damage of a stay or a connection member by local force can be avoided. As a result, the lifetime can be extended without forming a complicated reinforcing structure. In addition, by reducing the height of the connecting member, the height of the front end of the base can be adjusted to a low position, so it can be used in a wide range of applications from gently sloping roofs to the steep roofs. Can be applied to.

  Further, the base is made of a mold material having at least an upper wall and left and right side walls, and the connecting member includes an annular wall portion in which the wall is annularly arranged so as to form the through hole portion, and the annular wall portion.

The through hole is formed in a shape corresponding to the flat cross-sectional shape of the stay, and the pair of attachment pieces are inserted into the base and fixed to both side walls of the base. preferable. If comprised in this way, since the through-hole part of a connection member is formed in an annular wall part, the intensity | strength and rigidity of a connection member will become large.

  Moreover, it is preferable that the connection member is formed with a step portion between the annular wall portion and the pair of attachment pieces, and the annular wall portion is formed wider than the inner dimension width of the base. If comprised in this way, since the insertion position to the base of a connection member is positioned by this step part, the assembly workability | operativity of a roof stand improves.

  Moreover, it is preferable that the height dimension of the connecting member is substantially the same as the height dimension of the base. In this way, the height position of the front end portion of the base can be lowered to the extent that the lower surface of the base is attached to the upper surface of the front seat plate, so that the lower limit of the inclination angle of the installation location can be reduced. Therefore, the use range can be expanded over a wide range from a gently inclined roof, the ground, and the like to a steep roof.

  Moreover, it is preferable that the said connection member is made into the extrusion type | mold material extruded in the height direction. If the connecting member is manufactured by sheet metal bending, it is difficult to form the planar shape of the through hole portion into a square shape, and it becomes difficult to form the flat cross-sectional shape of the stay into a square shape. For this reason, restrictions on the appearance design become large, and it becomes difficult to form an appearance that looks good. However, when the connecting member is made of an extrusion mold in this way, a through hole having a desired planar shape can be easily formed. Therefore, it is possible to make the connecting member look good and to make the stay slide smoothly.

  Further, the connecting member has a bolt hole in a front wall forming a through hole portion, and the stay has a slit extending in a longitudinal direction in the front wall, and is inserted across the slit and the bolt hole. It is preferable that the connecting member and the stay are fixed by the bolts so that the front end portion of the base and the stay are fixedly connected. If it does in this way, since a bolt fastening operation can be performed from the front, the assembly workability | operativity of a roof stand improves.

  Further, in this case, the stay is made of a cylindrical extrusion mold member having a front wall, left and right side walls, and a rear wall, and the slit is formed in the front wall, and further, inside the slit in the front wall. It is preferable that a groove for accommodating the head of the bolt in a sliding manner is formed. When the stay is configured in this way, the strength of the stay is improved, the appearance is improved, and the bolt position is easily adjusted, so that the fastening operation is facilitated. Moreover, it becomes easy to set the external shape of a stay to the shape corresponding to the through-hole part of a connection member, and the slide of a stay with respect to the through-hole part of a connection member can be made smooth.

  The base has an upper wall, left and right side walls, and a lower wall, and the cross-sectional shape is substantially square, and the upper wall is formed with a slit in the longitudinal direction for mounting a vibration isolator for mounting an outdoor unit. It is preferable to consist of the extruded mold material. In this way, the appearance of the base can be improved and the strength of the base can be improved. In addition, when the connecting member is attached, when the attaching portion of the connecting member is inserted into the base, the connecting member is temporarily held at the attachment position with respect to the base, so that the assembling workability of the roof mounting base is improved.

  According to the roof mount of the air conditioner outdoor unit according to the present invention, when the air conditioner is mounted, a large force does not act on the plate material around the bolt head for fixing the stay or the nut, so that the life of the roof mount can be extended. . In addition, by reducing the height of the connecting member, the height of the front end of the base can be lowered, so that it can be applied to a wide range of applications from a gently sloping roof, the ground, etc. to a steep roof. be able to.

And the fixing position with the stay 6 with respect to the connection member 5 is defined according to the inclination | tilt angle of a roof, and the connection member 5 and the stay 6 are fixed at that position like FIG.

  Next, the connecting member 5 is attached to the front end portion of the base 4. As shown in FIGS. 1 and 6, the attachment is performed by inserting a pair of attachment pieces 53 of the connecting member 5 into the base 4 and confirming that the stepped portion 56 contacts the front end of the base 4. Since the height dimension of the connecting member 5 is formed so as to substantially match the inner dimension height of the cylindrical base 4, the side wall of the base 4 is in a state where the stepped portion 56 is in contact with the front end of the base 4. The screw hole 47 of 42 and the tapping screw hole 54 of the mounting piece 53 substantially correspond. Here, the connecting member 5 is attached to the front end portion of the base 4 with a tapping screw 57. Thereby, the stay 6 and the front end portion of the base 4 are connected and fixed, and the temporary assembly of the support member is completed.

  Next, the rear end of the temporarily assembled support member 3, that is, the rear end of the base 4 is attached to the rear seat plate 1, and the front end of the temporarily assembled support member 3, that is, the lower end of the stay 6 is attached. Attach to the front seat plate 2.

  As shown in FIGS. 3 and 4, the rear seat plate 1 is attached to the rear seat plate 1 so that the screw portion 15 b of the bolt 15 for attaching the base 4 protrudes upward. The head portion 15a of the bolt 15 is accommodated in one groove portion 14, and is slid to a predetermined position. Next, the threaded portion 15 b of the bolt (hexagon bolt) 15 is inserted into the bolt hole 48 formed in the lower wall 43 at the rear end portion of the base 4. Next, the nut 16 is fastened from above. In this way, the rear end portions of the pair of support members 3 are temporarily fixed to the rear seat plate 1.

  Next, the front end portion of the support member 3 is attached to the front seat plate 2 by placing the horizontal end surface of the square-shaped cutout portion 68 at the lower end portion of the stay 6 along the connecting wall portion 22. Prior to this placement, the head 25a of the bolt 25 is inserted into the groove 24, and the tip of the screw portion 25b is passed through the slit 64 provided in the front wall 61 of the stay 6 during placement. 3 and 5, the nut 26 is fastened at a substantially predetermined position in the longitudinal direction of the front seat plate 2 to attach the lower end portion of the stay 6 to the front seat plate 2. In this manner, the front end portions of the pair of support members 3 are temporarily fixed to the front seat plate 2.

  The roof mounting table temporarily assembled as described above is lifted on the roof R, and the roof mounting table is placed so that the rear seat plate 1 and the front seat plate 2 are arranged at predetermined positions. Next, the roof legs 19 and 29 are attached to the portions of the rear seat plate 1 and the front seat plate 2 that contact the roof. The roof legs 19 and 29 are attached to the first protrusions 17 and 27 and the second protrusions 18 and 28 of the contact walls 13 and 23 by engaging the engaging portions at the ends of the roof legs 19 and 29. Next, as shown in FIG. 2, the rear seat plate 1 is tethered and held on the wall surface of the building by the wire 71. One end of the wire 71 is fixed to the wall surface of the building by a hot nail 72, and the other end is wound around the rear seat plate 1 and fixed. Then, the height of the stay 6 is finally adjusted so that the base 4 is held horizontally corresponding to the inclination of the roof R. Further, it is confirmed whether or not the support member 3 is fixed at a predetermined position, and final adjustment is performed. The anti-vibration material 44 is fixed to the upper surface of the base 4 in the roof pedestal assembled and installed as described above.

  The air conditioner roof stand according to the present embodiment is installed in the state as shown in FIGS. 2 and 3 when installed on the roof R having a large inclination angle, but on the roof R or the ground having a small inclination angle. When installing, as shown in the side view of FIG. 9, the fixed position with respect to the stay 6 of the connection member 5 is set below. That is, as can be seen from FIGS. 3 and 9, by increasing the fixing position of the connecting member 5 with respect to the stay 6, it is possible to cope with installation on the roof R having a large inclination angle, and the stay 6 of the connecting member 5. By lowering the fixed position with respect to, it is possible to cope with installation on the roof R or the ground having a small inclination angle. Even if the inclination angle of the installation place such as the roof R or the ground changes, the base 4 is held horizontally and the stay 6 is held in the vertical direction. Is always in the horizontal direction, and the mounting wall portion 21 of the front seat plate 2 is always in the vertical direction. And if the inclination angle of installation places, such as roof R and the ground, changes, the contact part with the roof R, the ground, etc. in the contact wall part 13 of a backseat board and the contact wall part 23 of a front seat board will change. ing.

According to the roof mount of the air conditioner outdoor unit configured as described above, the following effects can be achieved.
(1) Since the stay 6 is penetrated into the through hole 51 of the connecting member 5 so as to be slidable and fixable, the height of the front end of the base 4 is set to a predetermined value by setting the through position to be fixed. Can be adjusted to the position.

  (2) In this case, the moment due to the load of the air conditioner placed on the base 4 is the front wall 52a and the rear wall 52b of the annular wall 52 forming the through hole 51 (see FIG. 7), the force does not act locally around the bolt even when bolted as in the prior art. For this reason, deformation or breakage of the stay 6 or the connecting member 5 due to local force can be avoided. As a result, the lifetime can be extended without forming a complicated reinforcing structure.

  (3) Moreover, since the height dimension of the connecting member 5 is formed small, that is, the height dimension of the connecting member 5 is substantially the same as the inner dimension height dimension of the base 4, the base 4 The height position of the front end portion of the base 4 can be lowered to such an extent that the lower surface of the base 4 comes into contact with the upper surface of the front seat plate 2. As a result, the lower limit of the inclination angle of the installation place can be reduced, and the use range can be expanded.

  (4) Moreover, since the connection member 5 is comprised from the annular wall part 52 and the pair of attachment pieces 53 in which the wall was arrange | positioned cyclically | annularly so that the through-hole part 51 may be formed, strength of the connection member 5 and Increases rigidity.

  (5) Since the connecting member 5 has a stepped portion 56 formed between the annular wall portion 52 and the pair of mounting pieces 53, the annular wall portion 52 is formed wider than the inner dimension width of the base 4. The step portion 56 can position the insertion of the connecting member 5 to the base 4 and improve the assembling workability of the roof stand.

  (6) Moreover, since the connection member 5 is formed as an extrusion mold material extruded in the height direction, a planar through-hole portion 51 that matches the planar shape of the stay 6 can be easily formed. The stay 6 can be smoothly slid in the through hole 51. Further, the connecting member 5 can be formed with good appearance.

  (7) The connecting member 5 has a bolt hole 55 in the front wall 52a of the annular wall portion 52, and the stay 6 has a slit 64 extending in the longitudinal direction in the front wall 61. The connecting member 5 and the stay 6 are fixed by a bolt 65 that is inserted across the base 64, whereby the front end of the base 4 and the stay 6 are fixedly connected.
