  By the way, the connection assisting member 105 includes a slit-like opening 164 that connects the screw portion 165b of the bolt 165 with the head 165a inserted into the inner back portion 166 provided on the front side of the stay 106, and an annular shape. It is configured to project outward through a bolt hole 155 provided in the wall portion 152, and to fasten a nut 167 to the projecting screw portion 165b. The inner back portion 166 and the opening 164 connected thereto constitute a slide groove for sliding the bolt 165. The nut 167 and the head 165a function as a clamping unit that clamps the annular wall 152 and the stay 106.

  The bolt 165 is attached to the stay 106 so as to be movable in the vertical direction by inserting the head 165a into the inner back 166 from the end of the inner back 166. The inner back 166 and the opening 164 As shown in FIG. 15, the center in the width direction of the inner back portion 166 and the center in the width direction of the opening portion 164 coincide, and the width dimension of the inner back portion 166 has a hexagonal shape. The width is set to be slightly larger than the width of the narrow portion 165a. Therefore, when the head portion 165a is inserted into the inner back portion 166, the head portion 165a is inserted into the inner back portion 166 if the narrow width portion of the head portion 165a is not aligned parallel to the width direction of the inner back portion 166. Since this is not possible, an operation for rotating the head 165a functioning as the clamping portion around its axis and aligning it with the inner back portion 166 is required, and improvement in workability has been desired.

  The present invention has been made in order to solve such a problem of the prior art, and an operation of aligning the clamping portion with respect to the inner back portion can be omitted, and workability can be improved. The purpose is to provide an installation base for air conditioner outdoor units.

  According to a first aspect of the present invention, in the air conditioner outdoor unit installation base having the first connecting member and the second connecting member that are connected to each other by the connecting tool, the connecting tool has two holding parts and an interval between the holding parts. The first connecting member includes an opening through which the shaft portion of the connector can be inserted, and one of the holding portions on the back side of the opening. Each of the sandwiching portions has a plurality of pairs of side surfaces opposed to each other with the shaft center of the sandwiching portion interposed therebetween, The inner back portion is formed so as to be biased in the width direction with respect to the opening portion, and is provided at a position where it collides with the top portion between adjacent ones of the side surfaces or the vicinity thereof when one of the holding portions is inserted. The first side wall formed and one of the clamping portions is rotated around the axis by the collision. And having a second side wall which is provided in a position that allows the rotation.

  According to a second aspect of the present invention, in the air conditioner outdoor unit installation stand according to the first aspect, the distance from the first side wall to the opening is such that the top portion of one of the clamping portions and the top portion of the shaft The opening portion is shorter than a value obtained by subtracting the diameter of the shaft portion from the dimension between the top portions on the opposite side across the center and the distance from the first side wall to the opening portion. The distance obtained by adding the width dimension is shorter than the length obtained by adding the diameter of the shaft to the half value, and the distance from the second side wall farther from the opening to the opening is It is the same as the half value or longer than the half value.

  According to a third aspect of the present invention, in the air conditioner outdoor unit installation stand according to the second aspect, the width dimension of the opening portion is set to the dimension between the side surfaces between a pair of side surfaces facing each other across the axis. It is characterized by being shorter than a half value of the dimension including the diameter of the part.

The invention according to claim 4 is the installation stand of the air conditioner outdoor unit according to claim 2 or 3,
The distance obtained by adding the width dimension of the opening to the distance from the first side wall to the opening is shorter than half of the dimension obtained by adding the diameter of the shaft to the dimension between the tops, and the dimension between the side surfaces. It is characterized in that it is at least half the value of the dimension including the diameter of the shaft.

  In the present invention, the inner back portion is formed so as to be biased in the width direction with respect to the opening, and when one of the sandwiching portions is inserted into the inner back portion, one top portion of the sandwiching portion or its vicinity If it is a state which faces the edge of the 1st side wall, the top part or its vicinity part collides with the edge of the 1st side wall, and one of the clamping parts rotates based on the collision. This rotation continues until the top no longer strikes the first side wall. And when a top part stops colliding with the 1st side wall, one side of a clamping part is inserted in an inner back part. Therefore, the operation of aligning the clamping part with respect to the inner back part becomes unnecessary, and workability can be improved.

  According to the invention of claim 2, when the shaft portion contacts the edge on the first side wall side of the opening, the distance from the first side wall to the opening is a dimension obtained by subtracting the diameter of the shaft portion from the dimension between the tops. Therefore, the top of one of the sandwiching portions or the vicinity thereof collides with the end of the first side wall. On the other hand, when the shaft is in contact with the edge of the opening on the second side wall, the distance obtained by adding the width of the opening to the distance from the first side wall to the opening is half the value of the shaft. Since it is shorter than the length dimension added with the diameter, the top part in one side of the clamping part or its vicinity collides with the end of the 1st side wall. At this time, since the distance from the second side wall far from the opening to the opening is the same as the half value or longer than the half value, the collision with the end of one first side wall of the clamping unit Along with this, one of the sandwiching portions reliably rotates around the axis, and one of the sandwiching portions enters the inner back portion. Further, the rotation around the axis of one of the sandwiching portions stops when the next top portion on the downstream side in the rotational direction comes into contact with the first side wall close to the opening, and both the sandwiching portions are clamped when the two sandwiching portions are fastened. The parts are prevented from co-rotating.

  In the case of the invention according to claim 3, even if one of the sandwiching portions rotates around the axis, and the side surface exposed to the opening is substantially parallel to the width direction of the opening, one of the sandwiching portions is It can be prevented from coming out of the opening.

  According to the fourth aspect of the present invention, the side surface on one side of the clamping portion can be brought close to the first side wall and substantially parallel. Preferably, the distance from the edge of the opening close to the second side wall to the first side wall is close to a value that is half the dimension obtained by adding the diameter of the shaft part to the dimension between the side surfaces. By doing in this way, the contact area of one of the clamping parts and an inner back part increases, and the fastening strength by both clamping parts can be improved.

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 mounting base assembled and installed as described above.

  Next, each structure of the opening part 64 of the slide groove, the inner back part 66, the head part (clamping part) 65a of the bolt, and the shaft part 65c of the bolt 65 and the mutual positional relationship will be described with reference to FIGS. To do.

  FIG. 9 shows that the head portion 65a of the bolt enters the inner back portion 66 as the stay 6 described above is inserted into the through hole portion 51 of the connection auxiliary member 5 from above or below (FIG. 8B). It is explanatory drawing regarding reference. FIG. 10 is a diagram showing the relationship between the parts when the shaft 65c of the bolt 65 contacts the edge of the opening 64 on the first side wall 66a side, and FIG. 11 shows the relationship between the parts of the bolt 65 and the second side wall of the opening 64. FIG. 12 is a diagram showing the relationship between the respective parts when contacting the edge on the 66b side, and FIG. 12 is a side view 65a-2 (strictly speaking, the bolt head 65a rotates around the axis 65d and is exposed to the opening 64. FIG. 13 is a diagram showing a dimensional relationship that prevents the head 65a from coming out of the opening 64 even when the edge of the side 65a-2 is substantially parallel to the width direction of the opening 64. FIG. It is a figure which shows the relationship of each part which makes 65a-2 approach the 1st side wall 66a, and can make it substantially parallel.

  In this embodiment, as shown in FIG. 9A, when the stay 6 is inserted into the through hole 51 of the connection assisting member 5 from above or below, the top 65a-1 of the bolt head 65a is If it is in a state facing the end of the first side wall 66a, the top portion 65a-1 or its vicinity collides with the end of the first side wall 66a, and as a result, the head 65a is moved as shown in FIG. Rotate. This rotation continues until the top 65a-1 does not collide with the first side wall 66a.

L1 <L2 (= (W1-D) / 2) (1)
L3 (= L1 + W2) <L4 (= L2 + D) (2)
L5 ≧ L2 (3)
Next, even if the head portion 65a of the bolt rotates around the axis and the second width portion 65a-2 becomes substantially parallel to the width direction of the opening portion 64, the head portion 65a does not come out of the opening portion 64. As shown in FIG. 12, the width dimension W2 of the opening 64 is obtained by adding the diameter D of the shaft 65c to the dimension W3 between the pair of side surfaces 65a-2 facing each other across the shaft center 65d. The condition is shorter than the half value ((W3 + D) / 2) (hereinafter referred to as the second condition).

  The second condition is expressed by the following (4).

W2 <(W3 + D) / 2 (4)
The half ((W3 + D) / 2) is equivalent to a value (L6 + D) obtained by adding D to a value L6 which is half of the value obtained by subtracting D from W3, as shown by the following equation (5).

(W3 + D) / 2 = L6 + D (5)
Furthermore, as shown in FIG. 9C, the condition that the side surface (side surface on the first side wall 66a side) of the second width portion 65a-2 is brought close to and substantially parallel to the first side wall 66a is as shown in FIG. As shown, the distance L3 obtained by adding the width dimension W2 of the opening 64 to the distance L1 from the first side wall 66a to the opening 64 is half of the dimension obtained by adding the diameter D of the shaft portion 65c to the inter-top dimension W1. The condition (hereinafter, the third condition) is shorter than the value ((W1 + D) / 2) and is not less than half the value ((W3 + D) / 2) of the dimension obtained by adding the diameter D of the shaft portion 65c to the inter-side dimension W3. Called).

  The third condition is expressed by the following formula (6).

(W3 + D) / 2 ≦ L3 (= L1 + W2) <(W1 + D) / 2 (6)
In addition, the half value ((W1 + D) / 2) of the former (the right side of the expression (6)) in the third condition is a dimension (W1-D) obtained by subtracting D from W1 as shown in the following expression (7). Is equivalent to a value obtained by adding D to a half value L2 (L2 + D), and a half value ((W3 + D) / 2) of the latter (the left side of the expression (6)) in the third condition is (8 This is equivalent to a value (L6 + D) obtained by adding D to half L6 of the dimension (W3-D) obtained by subtracting D from W3 as shown by the equation (1).

(W1 + D) / 2 = L2 + D (7)
(W3 + D) / 2 = L6 + D (8)
