Abstract

PROBLEM TO BE SOLVED: To facilitate a mounting work and reinforce mounting strength in a muntin type mount member of room air conditioner. SOLUTION: This mount member constitutes a mount by assembling an upper angle 10 and a lower angle 20 freely. An arc-shaped bending part 12 and a horizontal projecting part 13 are formed on the upper end of the upper angle 10 by bending a vertical part 11 to the front side while a slot screw hole 16 is formed, which leads to the projecting part 13 from the vertical part 11 by way of the bending part 12. An arc-shaped bending part 22 and a projecting part 23 are formed on the lower end of the lower angle 20 by bending the vertical part 21 to the front side while a long and screwed hole 26 is formed, which lead to a projecting part 23 from the vertical part 12 by way of the bending part 22. In the case when a screw is screwed through the screw holes 16 and 26, the screwing work can be simplified. The projecting parts 13 and 23 and the vertical parts 11 and 21 are firmly bonded with the mounting surface. It is, therefore, possible to prevent the angle from being floated up resultant from screwing work by slanting the upper end of the upper angle 10 and the lower end of the lower angle 20 to the rear side.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical rail type room air conditioner mounting tool used for mounting a room air conditioner on a wall surface between a peripheral edge and a gate.

[0002]

2. Description of the Related Art When installing a room air conditioner in a Japanese-style room,
A vertical mounting is used. This fixture is shown in FIG.
As shown in FIG. 2, two sets of vertical bars 3 are fixed between the peripheral edge 1 and the gate 2. Each vertical bar 3 has a telescopic structure in which a pair of upper and lower angles 4a, 4b are slidably combined in the longitudinal direction, and the open ends of the angles 4a, 4b, that is, the upper end and the lower end of the upper angle 4a. Angle 4
At the lower end of b, horizontal protruding portions 6 and 6 formed by bending the end of the vertical portion 5 at right angles to the front side and integrally forming the same are provided. The projections 6, 6 have angles 4a, 4
A pair of left and right screw holes 7, 7 (see FIG. 7) are provided for screwing b.

When a room air conditioner is mounted by using a vertical rail-type mounting tool, the length of the vertical rails 3 is determined according to the length between the peripheral edge 1 and the Kamoi 2. In this state,
Then, screw the air conditioner installation plate 8 called the back plate.
Upper and lower angles 4a, 4b by air conditioner installation plate 8
Are connected, and the length of the vertical rail 3 is fixed. And FIG.
As shown in FIG. 5, each vertical rail 3 is applied to the wall surface between the peripheral edge 1 and the gate 2, and the screw 9 is screwed into the lower surface of the peripheral edge 1 and the upper surface of the gate 2 through the screw holes 7, 7.

[0004] Thus, even in the case of a Japanese-style room where the screw 9 does not work on the wall surface, the air conditioner installation plate 8 can be attached to the wall surface, and the room air conditioner can be installed.

[0005]

In such a vertical beam type mounting device, the projecting portions 6, 6 of the upper and lower angles 4a, 4b are securely screwed on the lower surface of the peripheral edge 1 and the upper surface of the Kamoi 2 which are screwed surfaces. It is necessary to stop. However, that screw 9
Cannot be screwed at right angles to the screwing surface,
It will be inclined to the front side at a considerable angle. On the other hand, the projections 6, 6 are parallel to the threaded surface. Therefore, when looking at the propulsion direction of the screw 9, the screw hole 7 becomes elliptical, and depending on the inclination angle of the screw 9, the periphery of the screw hole 7 becomes an obstacle and the screw 9 cannot be screwed to the root. (See FIG. 7).

For this reason, in this type of attachment, it is necessary to make the screw 9 perpendicular to the screwing surface as much as possible. However, since the distance from the wall is short, the screwing operation is essentially difficult. is there. If the screw 9 cannot be screwed to the root, sufficient mounting strength cannot be obtained and the screw 9 is not screwed in smoothly.
Screwing work becomes more difficult. Also, depending on the situation,
There is a case where the vertical portion 5 is required to be in close contact with the wall surface.

[0007] In order to solve these problems, as shown in FIG. 8, a fixture in which the protruding portion 6 is inclined with respect to the vertical portion 5 is already partially used. With this fixture, the screwing is easier and smoother than with the previous fixture. In addition, the vertical portion 5 can be brought into close contact with the wall surface with a relatively large force. However, if the inclination angle of the projection 6 and the inclination angle of the screw 9 do not match, it is difficult to screw in again. Also, even if the screwing is done securely,
Since the protruding portion 6 has only an edge in linear contact with the mounting surface, there remains a problem that sufficient mounting strength is not ensured.

The present invention has been made in view of the above circumstances, and can easily and smoothly screw in a screw regardless of the screwing angle thereof, and can secure sufficient mounting strength. It is another object of the present invention to provide a vertical beam-type room air conditioner mounting fixture that can make a vertical portion adhere to a wall surface with a large force.

[0009]

SUMMARY OF THE INVENTION A room air conditioner mounting device according to the present invention is a vertical beam type room air conditioner mounting device which supports a room air conditioner by being bridged between a peripheral edge and a gate, and the like. It is provided with two sets of telescopic vertical rails in which the lower angle is slidably combined in the longitudinal direction, and at least one of the upper angle and the lower angle is on the open end side of the vertical part and the front side via the curved part. It is characterized in that it has a horizontal protruding portion bent inward, and a screw hole provided at an end portion for screwing is a long hole formed at least in the curved portion along the curve.

This curved end structure is preferably used for both the upper angle and the lower angle, but may be used for only one of them. Further, it is preferable that the end having the curved structure is inclined to the back side with respect to a portion other than the end. The upper angle and the lower angle are usually combined with the vertical bar and bridged between the surrounding rim and the Kamoi,
Only one of them can be used alone by hanging it around the periphery.

The elongated screw hole can be formed only in the curved portion of the angle. Further, it can be formed at a portion from the curved portion to the protruding portion or at a portion from the vertical portion to the curved portion. Further, it may be formed at a portion from the vertical portion to the projecting portion via the curved portion. Preferably, it is formed at least at a portion from the curved portion to the projecting portion, that is, a portion from the curved portion to the projecting portion, or a portion from the vertical portion to the projecting portion via the curved portion.

In the room air conditioner mounting device according to the present invention, since the screw hole is a long hole formed along at least the curved portion of the angle along the curve, when the screw is screwed into the screwing surface, how the screw is formed Even when inclined, the longitudinal end around the screw hole does not hinder screwing. Therefore, the screw can be smoothly screwed to the base regardless of the inclination angle of the screw. Since the protrusion is horizontal and comes into surface contact with the mounting surface, sufficient mounting strength is ensured. By pressing the curved portion with the screw, the vertical portion comes into close contact with the wall surface with a large force.

When the end having the curved structure is inclined rearward with respect to the portion other than the end, the lifting of the opposite end from the wall surface due to the screwing of the end is effective. Avoidance. This structure is particularly effective when only one of the upper angle and the lower angle is used alone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a vertical rail showing the configuration of a main part of an example of a room air-conditioner mounting device embodying the present invention, FIG. 2 is a diagram showing an AA line in FIG. 1, and FIG. FIG. 4 is a perspective view showing a use state of the room air conditioner fixture, and FIG. 5 is a longitudinal side view of an angle end showing a screwed state.

[0015] The room air conditioner fixture has a pair of right and left vertical rails. As shown in FIG. 1, each of the vertical rails has a telescopic structure in which upper and lower angles 10, 20 are slidably combined in the longitudinal direction.

The upper angle 10 includes a long vertical portion 11 extending along the wall surface, a curved portion 12 formed by bending an upper end portion of the vertical portion 11 in an arc toward the front by approximately 90 °, and a distal end side of the curved portion 12. And a horizontal protruding portion 13 which is provided continuously. The vertical portion 11 of the upper angle 10 has a portion excluding the upper end portion bulged in a trapezoidal shape toward the front side, leaving edges on both sides. A large number of screw holes 14 are formed at the top surface of the bulging portion at intervals in the longitudinal direction for mounting a mounting plate. These screw holes 14 are provided on one side of the top surface partly, and a relief hole 15 extending in the longitudinal direction is formed on the other side of the top surface part.

At the upper end of the upper angle 10, a pair of screw holes 16 for mounting the upper angle 10 are formed on both sides. Each screw hole 16 is a long hole that reaches the protruding portion 13 from the vertical portion 11 via the curved portion 12. Therefore,
The screw hole 16 is formed from three parts, a vertical part, a curved part, and a horizontal part. Below each screw hole 16 is a circular round screw hole 1.
7 are provided. There is a protrusion 1 between the screw holes on both sides.
An arc-shaped bulging rib 18 reaching the bulging portion of the vertical portion 11 from the tip end of the third portion 3 is formed. Reference numeral 17 'denotes an anchor hole used when there is an indoor unit anchor bolt.

The upper end of the upper angle 10 is also shown in FIG.
As shown in the figure, the projecting portion 13, the curved portion 12, and the vertical portion 11
The portion above the bulging portion is inclined to the rear side at an angle of θ with respect to the portion below the bulging portion. Although the inclination angle θ is not particularly limited, for example, 2 to 5 degrees is sufficient.

Like the upper angle 10, the lower angle 20 includes a long vertical portion 21 along the wall surface, and a curved portion 22 formed by bending the lower end of the vertical portion 21 in an arc shape toward the front side by approximately 90 °. The vertical portion 21 overlaps the rear side of the vertical portion 11 of the upper angle 10.

As shown in FIG. 2, the vertical portion 21 of the lower angle 20 has a portion excluding the lower end portion, which corresponds to the vertical portion 11 of the upper angle 10, and swells in a trapezoidal shape toward the front. It has been processed. On the other hand, both side edges of the vertical portion 11 of the upper angle 10 are curved in a U shape inward, and the lower angle 20
Of the vertical portion 21 are formed with slide grooves 19, 19 in which the side edges 29, 29 are fitted. As a result, the angles 10, 20 relatively move in the longitudinal direction, and the length of the vertical rail can be adjusted.

On the top surface of the vertical portion 21, a number of screw holes 24 are formed at intervals in the longitudinal direction for mounting a mounting plate. These screw holes 24 are located on the back side of the escape holes 15 provided in the vertical portion 11 of the upper angle 10. Also, the vertical portion 1 of the upper angle 10
A relief hole 25 extending in the longitudinal direction is formed on the back side of the screw hole 14 provided in the first hole 1.

At the lower end of the lower angle 20, a pair of screw holes 26, 26 for mounting the lower angle 20 are formed. Each screw hole 26 extends from the vertical portion 21 to the curved portion 2 similarly to the screw hole 16 formed in the upper angle 10.
It is a long hole that reaches the protruding portion 23 through 2. Therefore, the screw hole 26 is also formed of three parts, a vertical part, a curved part, and a horizontal part. Above each screw hole 26, a circular round screw hole 27 is provided. Between the screw holes on both sides, an arc-shaped rib 28 reaching the bulging portion of the vertical portion 21 from the tip of the projecting portion 23
Are formed. An anchor hole 27 'is used when there is an indoor unit anchor bolt.

As shown in FIG. 3 (b), the lower end of the lower angle 20 has a lower portion than the bulging portion of the projecting portion 23, the curved portion 22 and the vertical portion 21 with respect to a portion above it. To the rear side at an angle of θ. The inclination angle θ is not particularly limited, but 2 to 5 degrees is sufficient.

Next, the method of using the room air conditioner attachment will be described for a case where the room air conditioner is mounted on the wall surface between the periphery and the gate.

FIG. 4 (a) shows the fixture for the room air conditioner.
As shown in FIG. 4, one of the following methods is used: a method of supporting the room air conditioner by the peripheral edge 1 and the Kamoi 2 and a method of mounting the room air conditioner by suspending the room air conditioner as shown in FIG. be able to.

In the former case, the length of the vertical rails on both sides is determined by moving the upper angle 10 and the lower angle 20 in the longitudinal direction according to the length between the peripheral edge 1 and the gate 2.
In this state, the air conditioner installation plate 8 called a back plate is screwed to the upper angle 10 and the lower angle 20. At this time, the screw 3 is inserted into the screw hole 14 for the upper angle 10.
1 is screwed into the lower angle 20 and the screw 31 is screwed into the screw hole 24. However, in a portion where the upper angle 10 and the lower angle 20 overlap, the lower angle 20 is inserted through the escape hole 15 of the upper angle 10. A screw 31 is screwed into the screw hole 24, and the screw 31 screwed into the screw hole 14 of the upper angle 10 projects through the clearance hole 25 of the lower angle 20 to the rear side.

When the upper and lower angles 10 and 20 are connected by screwing the air conditioner installation plate 8 and the length of the vertical rail is fixed, as shown in FIG. And a screw 30 is screwed into the lower surface of the surrounding edge 1 through the screw hole 16 of the upper angle 10. Further, a screw is screwed into the upper surface of the gate 2 through the screw hole 26 of the lower angle 20. At this time, the screw 30 inclines to the front side with respect to the lower surface of the peripheral edge 1 and the upper surface of the Kamoi 2 which are the screwing surfaces. However, the screw holes 16 and 26 extend from the vertical portions 11 and 21 of each angle via the curved portions 12 and 22 to the projecting portions 13 and 2.
It is a long hole reaching 3. Therefore, even when the inclination angle of the screw 30 is large, the longitudinal ends around the screw holes 16 and 26 do not hinder the screwing, and each screw 30 is smoothly screwed to the root regardless of the inclination angle.

The screw 30 screwed to the root hits both sides of the curved portions of the screw holes 16 and 26, and the fixing force is effectively dispersed in the direction parallel to the direction perpendicular to the screwing surface. The vertical portion 11 is firmly pressed against the lower surface of the peripheral edge 1 and is firmly pressed against the wall surface between the peripheral edge 1 and the Kamoi 2. Further, since the protrusions 13 and 23 are both horizontal, they come into surface contact with the lower surface of the peripheral edge 1 and the upper surface of the Kamoi 2. Therefore, even when the vertical bar cannot be directly fixed to the wall surface between the peripheral edge 1 and the Kamoi 2, the vertical bar is firmly fixed between the peripheral edge 1 and the Kamoi 2 by a simple operation. In addition, circumference 1 and Kamoi 2
If the vertical beam can be fixed directly to the wall between
6, 26 vertical portions and round screw holes 17, 27 are used.

In this room air conditioner fixture, the curved portion 1
When the upper end of the upper angle 10 is screwed first, the lower end of the lower angle 20 tends to rise from the wall surface between the peripheral edge 1 and the gate 2 from the relation that the upper and lower ends of the upper angle 10 are screwed. However, the upper end of the upper angle 10 is inclined rearward with respect to the lower portion, and the upper angle 10
When viewed from the upper end portion, since the lower portion is inclined to the back side, the floating is suppressed.

When the latter mounting method is adopted, that is,
As shown in FIG. 4 (b), in the case of mounting the room air conditioner by hanging it on the peripheral edge 1, the upper end of the upper angle 10 is screwed to the peripheral edge 1 so that the lower end of the upper angle 10 is connected to the peripheral edge 1. The tendency to float up from the wall surface between the two is particularly strong, but the inclination of the upper end portion toward the back side can also effectively suppress the rising.

In the case of adopting the former mounting method, even if the lower end of the lower angle 20 rises from the wall surface between the peripheral edge 1 and the Kamoi 2, the lower end is screwed to the Kamoi 2 so as to be lifted. Will not hinder the subsequent installation of the air conditioner, but when this latter mounting method is used, if this rise occurs, the air conditioner installation plate 8 will jump up, and the air conditioner installation work on the air conditioner installation plate 8 will be hindered. Cause trouble. The inclination of the angle end is particularly effective when the latter mounting method is adopted.

Although the upper angle 10 is used in FIG. 4B, the room air conditioner can be hung on the peripheral edge 1 by using the lower angle 20. In this case, the inclination of the lower end of the lower angle 20 is effective.

[0033]

As described above, the room air conditioner mounting fixture according to the present invention has a horizontal projection bent to the front side through a curved portion at the open end side of the vertical portion of each angle constituting the vertical bar. The screw hole provided at the end for screwing is an elongated hole formed at least along the curve in the curved portion, so that the screw is rooted regardless of the inclination angle of the screw. It can be screwed up smoothly. Therefore, the installation work of the air conditioner is very simple. In addition, since the protruding portion is horizontal and comes into surface contact with the screwed surface, sufficient mounting strength is secured. Further, by pressing the curved portion with a screw, the vertical portion can be brought into close contact with the wall surface with a large force.

Further, when the angle end is inclined to the rear side, the lifting of the angle caused by pressing the curved portion with the screw can be suppressed, and the work of mounting the air conditioner can be facilitated.
