Description

Mounting plate

Technical Field

The present invention relates to an attachment plate used for wall-mounted installation of an installation object.

Background

Conventionally, in mounting an installation object such as an air conditioner on a wall surface, a mounting plate is widely used. By pre-attaching an attachment plate designed according to the installation object to a wall surface, workability in installing the installation object is improved (for example, see patent document 1).

A structure in which a support portion for locking the installation object is provided on the upper edge of the mounting plate is widely used, and the portion other than the support portion is a substantially flat plate-shaped main body portion, so that the entire mounting plate is easily bent by applying a load to the support portion. This increases the gap between the installation object and the wall surface, and also considers the risk that the support portion deforms and the installation object falls off from the support portion.

Detailed Description

(first embodiment)

Hereinafter, an attachment plate according to a first embodiment of the present invention will be described with reference to the 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. 1.

The attachment plate 20 (first embodiment 1) according to the first embodiment of the present invention is formed of, for example, metal, has a substantially rectangular flat plate-like body portion 10, and is locked with an installation object (not shown) corresponding to the attachment plate 20. Fig. 1 and 2 show a state as viewed from a surface facing an installation object, and hereinafter, for the sake of explanation, a surface facing an installation object may be referred to as a front surface, and a surface on the opposite side may be referred to as a rear surface. That is, the mounting plate 20 is mounted so that the rear surface thereof is in contact with a wall surface of a building or the like.

For the sake of explanation, in the thickness direction (front-rear direction) of the attachment plate 20, a direction away from the wall surface may be referred to as a front direction D1, and a direction toward the wall surface may be referred to as a rear direction D2. Further, with the center of the front surface of the attachment plate 20 as a reference, a direction toward the upper edge may be referred to as an upward direction H1, a direction toward the lower edge may be referred to as a downward direction H2, a direction toward the left edge may be referred to as a left direction W1, and a direction toward the right edge may be referred to as a right direction W2. The chain line in fig. 2 is a center line CL that indicates the center in the left-right direction (left direction W1 and right direction W2) of the main body 10.

The main body 10 is provided with a first disposition region a1 along the upper edge, a second disposition region a2 along the lower edge, and a third disposition region A3 between the first disposition region a1 and the second disposition region a 2. The body 10 has a rectangular cutout at the center of the lower edge, and the second disposition region a2 is divided into two regions, i.e., a left edge side and a right edge side.

The main body 10 is provided with reinforcing portions (a first reinforcing portion 11 and a second reinforcing portion 12) protruding in the front direction D1. The reinforcing portion is formed by bending a flat plate by drawing or the like without changing the periphery and thickness. In the present embodiment, the reinforcing portion is formed as a convex groove protruding in the forward direction D1, but may be formed as a concave groove protruding 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 of the first arrangement region a1, and are provided at positions that are line-symmetrical with respect to the center line CL. The two first reinforcing portions 11 extend in directions inclined with respect to the vertical direction (the upward direction H1 and the downward direction H2). Specifically, the lower end of the first reinforcing portion 11 provided on the left direction W1 side (left edge side) with respect to the center line CL is inclined to the left direction W1 with respect to the upper end. On the other hand, the lower end of the first reinforcing portion 11 provided on the side of the center line CL in the right direction W2 (the right edge side) is inclined in the right direction W2 with respect to the upper end. That is, the first reinforcing portion 11 is inclined in a direction in which the upper end is closer to the center line CL and the lower end is farther from the center line CL. 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 lines HL shown in fig. 2 indicate straight lines respectively along the direction in which the two first reinforcing portions 11 extend.

The second reinforcing portions 12 are provided at two locations of the second arrangement region a2, and are provided at positions that are line-symmetrical with respect to the center line CL, as in the case of the first reinforcing portions 11. The two second reinforcing portions 12 are disposed in the second disposition region a2 on the left edge side and the second disposition region a2 on the right edge side, respectively. The two second reinforcing portions 12 extend in a direction inclined with respect to the vertical direction. That is, the lower end of the left edge side second reinforcing portion 12 is inclined in the leftward direction W1 with respect to the upper end, and the lower end of the right edge side second reinforcing portion 12 is inclined in the rightward direction W2 with respect to the upper end.

The second reinforcing portion 12 is substantially parallel to the direction in which the first reinforcing portion 11 extends, and extends along substantially the same straight line. That is, the second reinforcing portion 12 on the left edge side is arranged to overlap the auxiliary line HL along the first reinforcing portion 11 on the left edge side, and the second reinforcing portion 12 on the right edge side is arranged to overlap the auxiliary line HL along the first reinforcing portion 11 on the right edge side.

In the first disposition region a1, upper fixing portions 13 are provided at three locations along the upper edge. In the second disposition region a2, the lower fixing portions 14 are provided at two locations along the lower edge. The upper fixing portion 13 and the lower fixing portion 14 are mounting holes for mounting the mounting plate 20 on the wall surface, and the mounting plate 20 is fixed to the wall surface by inserting screws or the like into the mounting holes and embedding the screws into 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 shape of the mounting plate 20.

In the mounting plate 20, it may be difficult to provide the reinforcing portion over the entire surface due to restrictions or the like caused by the structure of the mounted installation object. In the present embodiment, the third disposition region a3 is formed in a flat shape as a region facing a projection or the like of the installation object, thereby avoiding interference with the installation object.

In the present embodiment, the reinforcing portions provided in the divided regions are arranged so as to be associated with each other, and the reinforcing portions are configured to be reinforced by the two reinforcing portions in cooperation with each other. This can effectively increase the rigidity of the main body 10 and suppress deformation of the main body 10.

In general, the weight of the internal components of the installation object is also substantially line-symmetrical with respect to the mounting plate 20 having a substantially line-symmetrical shape, and therefore, it is preferable that the reinforcing portions are also arranged in line-symmetrical. This can efficiently improve the rigidity of the mounting plate 20.

Fig. 1 and 2 schematically show the mounting plate 20, and the structure of the locking installation is omitted. The structure of the locking member may be applied to a general structure, and a protrusion, a hole, or the like may be formed in the first arrangement region a1 or the second arrangement region a 2.

Next, a first comparative example 2 and a second comparative example 3 in which the reinforcing portions are arranged differently from the first example 1 will be described with reference to the drawings, and the structures and the rigidities thereof will be compared.

Fig. 3 is a front view of the mounting plate of the first comparative example.

In the first comparative example 2, the arrangement of the second reinforcing portion 12 is different from that in the first example 1. Specifically, in the first comparative example 2, the second reinforcing portion 12 extends in the left-right direction. That is, the second reinforcement portion 12 is inclined with respect to the auxiliary line HL.

Fig. 4 is a front view of the mounting plate of the second comparative example.

In the second comparative example 3, the arrangement of the second reinforcing portion 12 is different from that in the first example 1. Specifically, in the second comparative example 3, the second reinforcing portion 12 extends so as to be orthogonal to the auxiliary line HL.

Next, rigidity was compared in the computer simulation for first example 1, first comparative example 2, and second comparative example 3. In the computer simulation, the distribution of the amount of deformation in each portion of the mounting plate 20 was evaluated in the case where the fixing portions (the upper fixing portion 13 and the lower fixing portion 14) of the mounting plate 20 were fixed and the first reinforcing portion 11 was extended in the forward direction D1.

Fig. 5 is a characteristic diagram showing the result of the rigidity evaluation in the first example, fig. 6 is a characteristic diagram showing the result of the rigidity evaluation in the first comparative example, and fig. 7 is a characteristic diagram showing the result of the rigidity evaluation in the second comparative example.

Fig. 5 to 7 show the amount of deformation in each part of the mounting plate 20, and the amount of deformation is divided into predetermined values. As for the deformation amount, the first region R1 is smallest, and the second region R2, the third region R3,.. and the ninth region R9 are gradually larger in order. The first boundary line KL1 to the eighth boundary line KL8 represent the boundary lines of the respective regions. That is, the first boundary line KL1 represents the boundary line between the first region R1 and the second region R2, and the second boundary line KL2 represents the boundary line between the second region R2 and the third region R3.

In the first embodiment 1, the outer periphery is the first region R1 in which the amount of deformation is small, and is distributed so that the amount of deformation gradually increases toward the center of the body 10. The portion of the third disposition region A3 that faces the portion excluding the second disposition region a2 is deformed the most amount, and becomes the eighth region R8.

In the first comparative example 2, the deformation amount of the outer periphery is small and distributed so as to gradually increase toward the center of the body 10. In the first comparative example 2, unlike the first example 1, a ninth region R9 having a larger deformation amount than the eighth region R8 exists at substantially the center of the body 10.

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

In fig. 8, the deformation amount represents the maximum value in each of fig. 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, the deformation amount of the first example 1 was "4.73 mm", and the rigidity ratio was "100%". The deformation amount of the first comparative example 2 was "4.89 mm", and the rigidity ratio was "97%". The second comparative example 3 had a deformation amount of "5.02 mm" and a rigidity ratio of "94%". The small amount of deformation means high rigidity, and from the results shown in fig. 8, it is clear that the first example 1 is an excellent structure having higher rigidity than the first comparative example 2 and the second comparative example 3.

(second embodiment)

Next, an installation plate according to a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, since the structure is substantially the same as that of the first embodiment, the same reference numerals are used and the drawings and the description thereof are omitted.

In the mounting plate 20 (second embodiment 4) according to the second embodiment of the present invention, the arrangement of the second reinforcing portion 12 is different from that of the first embodiment 1. Specifically, in the second embodiment 4, the second reinforcing portion 12 is disposed closer to the center line CL than the corresponding auxiliary line HL. That is, in comparison with the first embodiment 1, the second reinforcing portion 12 on the left edge side is disposed so as 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 so as to be shifted in the left direction W1 with respect to the auxiliary line HL.

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

In fig. 9, the first reinforcing portion 11 is disposed closer to the center line CL than the second reinforcing portion 12, but the present invention is not limited thereto, and the first reinforcing portion 11 and the second reinforcing portion 12 may be disposed at positions that are spaced from the center line CL by the same distance in the left-right direction.

Next, a third comparative example 5 in which the reinforcing portion is arranged differently from the second example 4 will be described with reference to the drawings, and the structure and rigidity thereof will be compared.

Fig. 10 is a front view of the mounting plate of the third comparative example.

In the third comparative example 5, the direction in which the second reinforcing portion 12 is offset is different from that in the second example 4. Specifically, in the third comparative example 5, the second reinforcing portion 12 on the left edge side is disposed so as to be offset in the left direction W1 with respect to the auxiliary line HL, and the second reinforcing portion 12 on the right edge side is disposed so as to be offset in the right direction W2 with respect to the auxiliary line HL.

Next, in the same manner as in the first embodiment, the rigidity of the second example 4 and the third comparative example 5 was compared by computer simulation.

Fig. 11 is a characteristic diagram showing the result of rigidity evaluation in the second example, and fig. 12 is a characteristic diagram showing the result of rigidity evaluation in the third comparative example.

In the second embodiment 4, the amount of deformation of the outer periphery is small and distributed so that the amount of deformation gradually increases toward the center of the body 10. In the second embodiment 4, the eighth region R8 exists at substantially the center of the body 10 as in the first embodiment 1, but the range of the eighth region R8 is smaller than that in the first embodiment 1.

In the third comparative example 5, the distribution of the deformation amounts is substantially the same as that in the first comparative example 2, and a ninth region R9 having a larger deformation amount than the eighth region R8 exists substantially in the center of the body 10.

Fig. 13 shows, for comparison, the ratio of the deformation amount to the rigidity in the first example 1, together with the second example 4 and the third comparative example 5. The rigidity ratio in fig. 13 is calculated from the reciprocal of the deformation amount based on the deformation amount of the first embodiment 1. As a result, the deformation amount of the second example 4 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%". As is clear from the results shown in fig. 13, the second example 4 is an excellent structure having higher rigidity than the first example 1 and the third comparative example 5.

(third embodiment)

Next, an installation plate according to a third embodiment of the present invention will be described with reference to the drawings. The same reference numerals are given to the components having substantially the same functions as those of the first and second embodiments, and the description thereof is omitted.

Fig. 14 is a perspective view of a mounting plate according to a third embodiment of the present invention, and fig. 15 is a front view of the mounting plate shown in fig. 14.

The mounting plate 20 (third embodiment 6) according to the third embodiment of the present invention has a substantially rectangular flat plate-like body portion 10 and a reinforcing portion formed therein, as in the first embodiment 1. In the third embodiment 6, a support portion 16 is formed along the upper edge. The support portion 16 is formed to protrude in the forward direction D1, and the installation object is hooked and held by the support portion 16. The installation object may be provided with a recess, an opening, or the like as appropriate according to the shape of the support portion 16.

The structure for holding the installation object is not limited to this, and a projection, a hole, a recess, or the like may be provided in a part of the attachment plate 20, and a part of the installation object may be fitted and held. However, the center of gravity of the installation object is located at a position distant from the wall surface (main body portion 10) in the forward direction D1, and the weight of the installation object acts so as to peel the installation object from the attachment plate 20 by applying a vertically downward force (downward direction H2). Therefore, in order to reduce the stress applied to the support portion 16, it is preferable to provide the support portion 16 near the upper edge of the mounting plate 20.

The main body 10 has substantially the same shape as that of the first embodiment 1, and is defined by a first disposition region a1 along the upper edge, a second disposition region a2 along the lower edge, and a third disposition region A3 between the first disposition region a1 and the second disposition region a 2. The body 10 has a rectangular cutout in the center of the lower edge, and the second disposition area a2 is divided into two regions, i.e., a left edge side and a right edge side.

In the third embodiment 6, a plurality of first reinforcing portions 11 are provided in the first arrangement region a1, and a plurality of second reinforcing portions 12 are provided in the second arrangement region a 2. The first reinforcing portion 11 and the second reinforcing portion 12 extend in a direction inclined with respect to the vertical direction. That is, the lower ends of the first reinforcing portion 11 and the second reinforcing portion 12 on the left edge side are inclined in the leftward direction W1 with respect to the upper ends, and the lower ends of the first reinforcing portion 11 and the second reinforcing portion 12 on the right edge side are inclined in the rightward direction W2 with respect to the upper ends. In addition, all of the first reinforcing portion 11 and the second reinforcing portion 12 may not be inclined in the same direction, and a reinforcing portion having a lower end inclined in the rightward direction W2 with respect to the upper end may be provided on the left edge side, or a reinforcing portion having a lower end inclined in the leftward direction W1 with respect to the upper end may be provided on the right edge side. In addition, a reinforcing portion parallel to the vertical direction may be formed together with a reinforcing portion inclined with respect to the vertical direction. Fig. 15 shows an auxiliary line HL extending along one of the first reinforcing parts 11 and a center line CL similar to that of the first embodiment.

The main body 10 is provided with an engraved area a4 where an imprint or the like is engraved. The mark is, for example, a character, a symbol, or the like, and indicates a description or the like when the mounting plate 20 or the installation object is installed. The imprint is formed by providing unevenness on the mounting plate 20 by drawing, and is preferably provided so as to avoid the reinforcing portion and the like. In fig. 15, the two-part imprint region a4 is shown in consideration of the ease of view of the drawing, but the present invention is not limited to this, and may be appropriately arranged in a plurality of parts.

Outer edge reinforcing portions 17 protruding in the forward direction D1 are provided at portions of the outer edge portions of the first arrangement region a1 and the second arrangement region a 2. The outer edge portions of the first arrangement region a1 and the second arrangement region a2 correspond to the outer edge of the mounting plate 20 itself or the boundary portion with the third arrangement region A3, and the reinforcing effect by the first reinforcing portion 11 or the second reinforcing portion 12 is weakened. Therefore, by providing the outer edge reinforcement portion 17, the rigidity can be effectively improved.

In the third arrangement region a3, the third reinforcement parts 15 are provided so as to protrude less in the forward direction D1 than the first reinforcement parts 11 and the second reinforcement parts 12. As described above, by providing the third reinforcing portion 15 to such an extent that the third reinforcing portion does not obstruct the installation of the installation object, the portion susceptible to the load can be reduced, and the rigidity can be further improved. The direction in which the third reinforcing portion 15 extends may be set as appropriate, and for example, any one of the third reinforcing portions 15 extends in parallel with the auxiliary line HL.

In the present embodiment, the upper fixing portions 13 are provided at five locations along the upper edge, and the lower fixing portions 14 are provided at three locations along the lower edge.

The first reinforcing portion 11, the second reinforcing portion 12, the third reinforcing portion 15, and the outer edge reinforcing portion 17 are provided in a plurality so as to be substantially line-symmetrical with respect to the center line CL. By disposing in this way, the load can be equally dispersed, and the torsional rigidity can be improved. The reinforcing portions may be formed in a winding or partially discontinuous shape so as to avoid the fixing portions, the notches, the embossed regions a4, and the like provided in the mounting plate 20.

Although not shown in fig. 14 and 15, the mounting plate 20 is provided with a plurality of through holes for weight reduction, assistance of a fixing portion, and the like. The through-hole may be provided so as to avoid the reinforcing portion, the mark, or the like, and may be appropriately arranged according to the shape of the mounting plate 20.

Fig. 16 is a schematic cross-sectional view showing the vicinity of the first reinforcing portion or the second reinforcing portion, and fig. 17 is a schematic cross-sectional view showing the vicinity of the third reinforcing portion.

The mounting plate 20 is a steel plate having a plate thickness of 0.5mm, and the protruding amount (first protruding length LN1) of the first reinforcing portion 11 and the second reinforcing portion 12 is 2 mm. The protruding amount of extrusion (second extrusion length LN2) of the third reinforcing portion 15 was 1 mm.

Next, a fourth comparative example 7 in which the reinforcing portion is arranged differently from the third example 6 will be described with reference to the drawings, and the structure and rigidity thereof will be compared.

In the fourth comparative example 7, the convex groove for reinforcing the mounting plate 20 is provided, for example, along the vertical direction or the horizontal direction of the mounting plate 20, like the vertical reinforcing portion 101.

Next, in the same manner as in the first embodiment, rigidity was compared in the third example 6 and the fourth comparative example 7 by computer simulation.

Fig. 19 is a characteristic diagram showing the result of rigidity evaluation in the third example, and fig. 20 is a characteristic diagram showing the result of rigidity evaluation in the fourth comparative example.

In the third embodiment 6, the amount of deformation of the outer periphery is small, and the distribution of the amount of deformation is gradually increased toward the center of the body 10. In the third embodiment 6, an eighth region R8 is present at a position slightly toward the left direction W1 from the substantially center of the body 10.

In the fourth comparative example 7, the amount of deformation progresses in a distribution similar to that of the third example 6, but there is a ninth region R9 having a larger amount of deformation than the eighth region R8 at a position slightly closer to the left direction W1 from the substantial center of the main body portion 10.

The rigidity ratio in fig. 21 is calculated from the reciprocal of the deformation amount based on the deformation amount of the third example 6. As a result, the deformation amount of the third example 6 was "6.76 mm", and the rigidity ratio was "100%". The fourth comparative example 7 had a deformation amount of "9.14 mm" and a rigidity ratio of "74%". As is clear from the results shown in fig. 21, the third example 6 is an excellent structure having higher rigidity than the fourth comparative example 7.

As described above, in the structure of the present invention, the reinforcement efficiency by the grooves (reinforcement portions) is better than that of the conventional structure, and therefore, the area ratio of the groove portions in the mounting plate 20 can be minimized. As a result, since a large space can be secured in the body 10 other than the groove, the fixing portion can be arranged from the ground, and the mounting plate 20 can be reduced in weight by providing a large hole.

Further, by using the mounting plate 20 of the present invention, the main body 10 can be thinned while maintaining the same rigidity. By making the thickness of the main body 10 thin, material cost and weight can be reduced, and workability during manufacturing and mounting operations can be improved.

Further, by minimizing the area ratio occupied by the groove portions, distortion of the periphery of the groove portions due to stretching by the stretching process and bending of the entire metal plate can be suppressed, and the quality at the time of manufacturing can be improved and stabilized.

The installation object installed by using the installation plate 20 of the present invention is not limited to the indoor unit of the air conditioner, and is applicable to a structure for holding a heavy object by using a plate material or an electrical product installed on a wall such as a wall-mounted television and a speaker. The mounting plate 20 can be used as a flat plate requiring rigidity while suppressing deformation due to external force. For example, the present invention can be applied to a metal plate outer cover, a top plate, a bottom plate, and a metal plate component for holding an internal motor, which are used in an outdoor unit of an air conditioner.
