Description

Mounting plate

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a mounting plate used for wall hanging installation of an installation.

Conventionally, when attaching an installation such as an air conditioner to a wall surface, the use of a mounting plate is widely adopted. By installing a mounting plate designed in accordance with the installation on a wall in advance, the workability at the time of installing the installation is improved (see, for example, Patent Document 1).

The mounting plate has a widely adopted structure in which a support is provided on the upper edge to lock the installation, but most of the parts other than the support are flat plate-like main parts, and the load is applied to the support By this, the entire mounting plate is easily bent. As a result, the gap between the installation and the wall increases, and there is also a possibility that the support may be deformed and the installation may fall off the support.

Hereinafter, the installation board concerning a 1st embodiment of the present invention is explained with reference to drawings.

FIG. 1 is a perspective view of a mounting plate according to a first embodiment of the present invention, and FIG. 2 is a front view of the mounting plate shown in FIG.

The mounting plate 20 (the first embodiment 1) according to the first embodiment of the present invention is made of, for example, metal, etc., has a substantially rectangular flat-plate shaped main body 10, and corresponds to the mounting plate 20. The installation (not shown) is locked. 1 and 2 show the state viewed from the side facing the installation, and for the purpose of the description, the side facing the installation may be called the front and the opposite side may be called the rear. . That is, the mounting plate 20 is attached such that the rear surface is in contact with the wall surface of a building or the like.

In the following, in the thickness direction (front-rear direction) of the mounting plate 20, the direction away from the wall surface may be referred to as the front direction D1, and the direction toward the wall surface may be referred to as the back direction D2. With reference to the center of the front surface of the mounting plate 20, the direction toward the upper edge is referred to as the upward direction H1, the direction toward the lower edge is referred to as the downward direction H2, and the direction toward the left edge is referred to as the left direction W1. The direction toward the edge may be referred to as the right direction W2. The alternate long and short dash line in FIG. 2 is a center line CL that represents the center of the main body 10 in the left-right direction (left direction W1 and right direction W2).

The main body portion 10 includes a first arrangement area A1 along the upper edge, a second arrangement area A2 along the lower edge, and a third arrangement area A3 between the first arrangement area A1 and the second arrangement area A2. Is set. The main body portion 10 is provided with a rectangular notch at the center of the lower edge, and the second placement area A2 is divided into two parts, the left edge side and the right edge side.

The main body portion 10 is provided with reinforcing portions (the first reinforcing portion 11 and the second reinforcing portion 12) which project in the forward direction D1. The reinforcing portion is formed by bending a flat plate by drawing or the like without changing its thickness from the periphery. In the present embodiment, the reinforcing portion is a convex groove projecting in the forward direction D1, but may be a concave groove projecting in the backward direction D2. The cross section of the reinforcing portion will be described in detail with reference to FIG. 16 described later.

The first reinforcing portions 11 are provided at two locations in the first arrangement region A1, and are provided at positions that are line-symmetrical with respect to the center line CL. In addition, each of the two first reinforcements 11 is drawn in a direction inclined with respect to the vertical direction (upward direction H1 and downward direction H2). Specifically, the lower end of the first reinforcing portion 11 provided on the left direction W1 side (left edge side) of the center line CL is inclined such that the lower end is directed to the left direction W1 than the upper end. On the other hand, the lower end of the first reinforcing portion 11 provided on the right direction W2 side (right edge side) from the center line CL is inclined such that the lower end is directed to the right direction W2 than the upper end. That is, the upper end of the first reinforcing portion 11 approaches the center line CL, and the lower end is inclined in the direction away from the center line CL. Further, the first reinforcing portion 11 on the left edge side and the first reinforcing portion 11 on the right edge side are inclined at substantially the same angle with respect to the vertical direction. The auxiliary line HL shown in FIG. 2 represents a straight line along the direction in which each of the two first reinforcements 11 is drawn.

The 2nd reinforcement part 12 is provided in two places of the 2nd arrangement field A2, and like the 1st reinforcement part 11, it is provided in the position which serves as line symmetry to central line CL. The two second reinforcements 12 are disposed in each of the second placement area A2 on the left edge side and the second placement area A2 on the right edge side. And each of the two 2nd reinforcement parts 12 is extended in the direction which inclined to the up-and-down direction. That is, the lower end of the second reinforcing portion 12 on the left edge side is inclined so that the lower end is directed to the left direction W1 than the upper end, and the lower end of the second reinforcing portion 12 on the right edge is directed to the right direction W2 than the upper end It is inclined to

The second reinforcing portion 12 is substantially parallel to the first reinforcing portion 11 and extends along substantially the same straight line.

Further, lower fixing portions 14 are provided at two places along the lower edge in the second arrangement area A2. The upper fixing portion 13 and the lower fixing portion 14 are attachment holes for attaching the mounting plate 20 to the wall surface, and screws and the like pass through the mounting holes and are embedded in the wall surface, and the mounting plate 20 is fixed to the wall surface. The number of the upper fixing portions 13 and the lower fixing portions 14 is not limited to this, and may be appropriately changed according to the size and the shape of the mounting plate 20.

In the case of the mounting plate 20, it may be difficult to provide the reinforcing portion on the entire surface due to the restriction due to the structure of the installation object to be attached. In the present embodiment, the third arrangement area A3 has a flat shape and is an area facing the protrusions of the installation object, etc., so as to avoid interference with the installation object.

In the present embodiment, reinforcement portions provided in separated regions are arranged in association with each other, and two reinforcement portions reinforce each other. Thereby, the rigidity of the main body portion 10 can be effectively enhanced, and the deformation of the main body portion 10 can be suppressed.

In addition, in general, the weight of the internal parts of the installation is also substantially line-symmetrical to the mounting plate 20 having a substantially line-symmetrical shape, so it is preferable that the reinforcing portions be also arranged in line-symmetrical manner. . Thereby, the rigidity of the mounting plate 20 can be efficiently enhanced.

1 and 2 schematically show the mounting plate 20, and the structure for locking the installation is omitted. A general structure may be applied as a structure for locking the installation, and a protrusion, a hole, or the like may be formed in the first arrangement area A1 or the second arrangement area A2.

It is a characteristic view which shows the evaluation result of the rigidity in a comparative example.

FIGS. 5 to 7 show the amount of deformation of each part of the mounting plate 20, and the amount of deformation is divided into predetermined values. The deformation amount is smallest in the first region R1, and gradually increases in the order of the second region R2, the third region R3, ..., and the ninth region R9. The first boundary line KL1 to the eighth boundary line KL8 indicate the boundaries of the respective regions. That is, the first boundary line KL1 indicates the boundary between the first region R1 and the second region R2, and the second boundary line KL2 indicates the boundary between the second region R2 and the third region R3.

In the first embodiment, the outer periphery is a first region R1 having a small amount of deformation, and the amount of deformation gradually increases toward the center of the main body portion 10. The amount of deformation of a portion facing the portion where the second arrangement area A2 is cut out, which is the center of the third arrangement area A3, is the largest, and is an eighth area R8.

In the first comparative example 2, the amount of deformation of the outer periphery is small, and the amount of deformation gradually increases toward the center of the main body portion 10. In the first comparative example 2, unlike the first example 1, a ninth area R9 having a larger deformation amount than the eighth area R8 is present substantially at the center of the main body portion 10.

In the second comparative example 3, the distribution of the deformation amount is substantially the same as that of the first comparative example 2, and the range of the ninth region R9 is wider than that of the first comparative example 2.

FIG. 8 is a characteristic chart showing the relationship between the amount of deformation and the rigidity ratio in the first embodiment, the first comparative example, and the second comparative example.

In FIG. 8, the deformation amount indicates the maximum value in each of FIGS. 5 to 7, and the rigidity ratio is calculated from the reciprocal of the deformation amount based on the deformation amount of the first embodiment 1. As a result, in the first example 1, the deformation amount was “4.73 mm” and the rigidity ratio was “100%”. The first comparative example 2 had a deformation amount of “4.89 mm” and a rigidity ratio of “97%”. The second comparative example 3 had a deformation amount of “5.02 mm” and a rigidity ratio of “94%”. The smaller the amount of deformation, the higher the rigidity, and the result shown in FIG. 8 shows that the first embodiment 1 has an excellent structure with higher rigidity than the first comparative example 2 and the second comparative example 3. It is understood that

In the installation board 20 (2nd Example 4) which concerns on 2nd Embodiment of this invention, arrangement | positioning of the 2nd reinforcement part 12 differs with respect to 1st Example. Specifically, in the second embodiment, the second reinforcing portion 12 is disposed at a position closer to the center line CL than the corresponding auxiliary line HL. That is, compared with the first embodiment, the second reinforcing portion 12 on the left edge side is disposed to be shifted in the right direction W2 with respect to the auxiliary line HL, and the second reinforcing portion 12 on the right edge side is disposed with respect to the auxiliary line HL. It is disposed to be shifted in the left direction W1.

As described above, one of the first reinforcing portion 11 and the second reinforcing portion 12 which is far from the center line CL is disposed closer to the center line CL than the straight line (auxiliary line HL) extended along the other. ing. Therefore, the deformation of the main body 10 can be further suppressed by bringing the reinforcing portion closer to the center where the load is concentrated.

In FIG. 9, the first reinforcing portion 11 is disposed at a position closer to the center line CL than the second reinforcing portion 12, but the present invention is not limited to this. The first reinforcing portion 11 and the second reinforcing portion 12 However, in the left and right direction, they may be disposed at positions equally spaced from the center line CL.

FIG. 10 is a front view of a mounting plate according to a third comparative example.

The third comparative example 5 is different from the second example 4 in the direction in which the second reinforcing portion 12 is shifted. Specifically, in the third comparative example 5, the second reinforcing portion 12 on the left edge side is disposed to be shifted in the left direction W1 relative to the auxiliary line HL, and the second reinforcing portion 12 on the right edge side is disposed relative to the auxiliary line HL. It is disposed to be shifted in the right direction W2.

In FIG. 13, the deformation amount and the rigidity ratio of the first embodiment 1 are shown together with the second embodiment 4 and the third comparative example 5 for comparison. The rigidity ratio in FIG. 13 is calculated from the reciprocal of the amount of deformation based on the amount of deformation of the first embodiment. As a result, in the second example 4, the deformation amount was “4.43 mm” and the rigidity ratio was “107%”. The third comparative example 5 had a deformation amount of “4.92 mm” and a rigidity ratio of “96%”. From the results shown in FIG. 13, it can be seen that the second embodiment 4 has an excellent structure with higher rigidity than the first embodiment 1 and the third comparative example 5.
