Description

[Technical field]

[0001] The present invention relates to an appliance mounting plate used for mounting appliances such as electrical appliances. [Background technology]

[0002] The above-mentioned appliance mounting plate is used to mount an electrical appliance, such as an electricity meter, on a target mounting location such as a wall surface, and is provided with a rectangular plate-shaped main body made of synthetic resin, in which screw-receiving recesses are formed for fixing set screws that mount the electrical appliance (see, for example, Patent Document 1).

[0003] The appliance mounting plate described in Patent Document 1 has many screw-in recesses that are continuous in the vertical and horizontal directions of the main body, making it easy to align the fixing position of a set screw with one of the many screw-in recesses. When mounting an electrical appliance, a set screw that has passed through a mounting hole or the like of the electrical appliance is aligned with one of the screw-in recesses, and the set screw is fixed in the screw-in recess, thereby mounting the electrical appliance in the desired mounting position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 2620747 Summary of the Invention [Problem to be solved by the invention]

[0005] In the instrument mounting plate described in Patent Document 1, screw-insertion recesses for fixing set screws are formed on the front and back surfaces of the main body, but if the screw-insertion recesses are placed too close to each other, problems such as weakening of the strength around the screw-insertion recesses can occur. Therefore, a new configuration must be provided to solve this problem, which may lead to a more complicated configuration and increased costs.

[0006] Furthermore, the required size of such an instrument mounting plate varies depending on the mounting conditions, such as the size and number of instruments to be mounted, the size of the installation space, etc., and it is required to be able to accommodate changes in the required size. In order to meet this demand, it is conceivable to manufacture main bodies of multiple sizes, but increasing the number of sizes would increase manufacturing costs, leading to increased costs.

[0007] In view of this situation, a main object of the present invention is to provide an instrument mounting plate that can flexibly accommodate changes in required size while simplifying the configuration and reducing costs. [Means for solving the problem]

[0008] A first characteristic configuration of the present invention is a plate-shaped unit body made of resin, and a positioning groove is formed in the unit body so as to expose the positioning line and extend in a first direction along the positioning line, The unit main body has a front surface and a back surface as attachment surfaces for an appliance, The positioning grooves are formed at a predetermined constant pitch in a second direction perpendicular to the first direction on both the front and back surfaces of the unit main body, The feature is that a connecting portion is provided that can freely connect a unit main body portion for surface portion attachment, whose front portion is the attachment surface portion of the device, and a unit main body portion for back portion attachment, whose back portion is the attachment surface portion of the device, in a state where they are adjacent to each other in the second direction.

[0009] According to this configuration, since the positioning groove is for making the positioning line appear, it can be, for example, a simple shape that is merely recessed, or a shallow groove. This eliminates the need to make the positioning groove itself a complex shape or to provide holes that weaken the strength, making it difficult for problems such as weakening the strength around the positioning groove to occur, and does not require a new configuration to solve the problem.

[0010] Moreover, since a connecting portion is provided that can connect the unit main body portion for mounting on the front surface portion and the unit main body portion for mounting on the back surface portion, the size of the instrument mounting plate can be changed by changing the number of unit main body portions to be connected according to the size required for the instrument mounting plate. Of course, the instrument mounting plate can also be constructed from a single unit main body portion, so that it can flexibly respond to changes in the required size.

[0011] When a unit main body part for mounting on the front side and a unit main body part for mounting on the back side are connected by a connecting part, positioning grooves are present at a predetermined constant pitch in the second direction across the unit main body part for mounting on the front side and the unit main body part for mounting on the back side on both the front side and the back side of the two connected unit main body parts. As a result, not only when an instrument mounting plate is formed with one unit main body part, but also when an instrument mounting plate is formed by connecting a unit main body part for mounting on the front side and a unit main body part for mounting on the back side by a connecting part, the positioning grooves are similarly present at a predetermined constant pitch in the second direction. Therefore, the positioning of the instrument to be mounted and a fixing device such as a set screw can be easily and appropriately performed using the positioning line parts that appear by the positioning grooves, so that the installation work of the instrument using the instrument mounting plate can be easily and appropriately performed.

[0012] A second characteristic configuration of the present invention is that the connecting portions are arranged at both ends of the unit main body portion in the second direction, and the positioning groove portions are formed at a predetermined constant pitch in the second direction in the connecting portions as well, in a state where they are continuous with the positioning groove portions formed in the unit main body portion.

[0013] According to this configuration, the connecting parts are disposed at both ends of the unit main body parts in the second direction, and the connecting parts have positioning grooves formed therein in a state continuous with the positioning grooves formed in the unit main body parts. This allows the positioning lines to be made to appear even in the connecting parts that serve as connecting points for connecting the unit main body parts together, and the positioning lines can be used to easily and appropriately position the fixture to be attached, or a fixing device such as a set screw.

[0014] A third characteristic configuration of the present invention is that the connecting portion is provided with a groove forming portion at the edge portion in the second direction, and when the unit main body portion for attachment to the front surface portion and the unit main body portion for attachment to the back surface portion are connected by the connecting portion in a state in which they are adjacent to each other in the second direction, the positioning groove portion is formed at the joint by the groove forming portion.

[0015] According to this configuration, when a unit main body part for mounting on the front surface part and a unit main body part for mounting on the back surface part are connected by a connecting part while being adjacent to each other in the second direction, a positioning groove part is formed at the joint by the groove forming part, so that the positioning groove part is not interrupted even at the joint part between the unit main body parts, and the positioning groove part can be present at a predetermined constant pitch in the second direction throughout the entirety of the multiple connected unit main body parts. Therefore, since a fixing device such as a set screw can be appropriately positioned not only at the joint part but also at the joint part, the position at which the fixing device is positioned can be freely selected, and the efficiency of the positioning work of the fixing device can be improved.

[0016] A fourth characteristic configuration of the present invention is that the connecting portion is configured as an engagement type connecting portion that engages and connects the unit main body portion for attachment to the front surface portion and the unit main body portion for attachment to the back surface portion.

[0017] According to this configuration, the connecting portion is of an engagement type that connects the unit main body parts by engaging them with each other, so that the unit main bodies can be connected simply by engaging them with each other, which simplifies the connecting work while allowing the unit main body parts to be accurately connected to each other.

[0018] A fifth characteristic feature of the present invention is that the unit main body portion is formed of a foamed resin molded product obtained by foaming a foamed resin material.

[0019] According to the present invention, by forming the unit main body portion from a foamed resin molded product, it is possible to reduce the weight of the unit main body portion while ensuring sufficient strength. [Brief description of the drawings]

[Figure 6] FIG. 1 is an exploded perspective view showing an electrical appliance being attached to an appliance mounting plate; [Figure 7] FIG. 1 is a perspective view showing an electrical appliance attached to an appliance mounting plate; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an instrument mounting plate according to the present invention will be described with reference to the drawings. 7, this appliance mounting plate 1 is used for mounting an electric appliance 11, such as a watt-hour meter, to a mounting location 12, such as a wall or a pillar. In this way, when mounting the electric appliance 11 to the mounting location 12, the electric appliance 11 is not mounted directly to the mounting location 12, but is mounted to the mounting location 12 via the appliance mounting plate 1.

[0022] As shown in Fig. 1, the instrument mounting plate 1 is provided with a resin plate-like unit body 2. The unit body 2 is formed in a rectangular shape and is composed of a foamed resin molded product formed by extruding and foaming a foamed resin material. The unit body 2 is formed with a positioning groove 4 extending in a first direction (the up-down direction in Figs. 1(A) and (B)) along the positioning line 3 to make the positioning line 3 appear.

[0023] 6, when mounting an electric appliance 11 on an appliance mounting plate 1, the electric appliance 11 is mounted on the appliance mounting plate 1 using a set screw 6. The positioning line portion 3 is used to determine the fixing position of the set screw 6. The positioning line portion 3 can be used not only to position the set screw 6, but also to position the electric appliance 11, for example, by installing the electric appliance 11 along the positioning line portion 3.

[0024] 1 and 2, the unit main body 2 has a front surface 2a and a back surface 2b formed in the same plane. Since an electric appliance 11 (see FIG. 7) can be attached to the front surface 2a of the unit main body 2 or to the back surface 2b of the unit main body 2, both the front surface 2a and the back surface 2b of the unit main body 2 are provided as surfaces to which the electric appliance 11 can be attached.

[0025] 1(A), (B) and 2, the positioning grooves 4 are formed at a predetermined constant pitch (e.g., 5 mm) in a second direction perpendicular to the first direction (left-right direction in Figs. 1(A) and (B)) not only on the front surface 2a of the unit main body 2 but also on both surfaces, that is, the front surface 2a and the back surface 2b. As shown in the enlarged downward view in Fig. 1(D), the positioning grooves 4 are formed in a semicircular cross-sectional shape (e.g., semicircular shape with a radius of 0.5 mm) with the front surface 2a or the back surface 2b recessed toward the opposite side, and are formed in a straight line extending along the first direction (up-down direction in Figs. 1(A) and (B)).

[0026] In this way, by forming the positioning grooves 4 on both sides of the front surface 2a and the back surface 2b, the positioning grooves 4 are present at a predetermined constant pitch in the second direction, whether the unit body 21 (the unit body 2 on the left in FIG. 3) for front surface mounting is used with the front surface 2a of the electrical appliance 11 (see FIG. 7) or the unit body 22 (the unit body 2 on the right in FIG. 3) for back surface mounting is used with the back surface 2b of the electrical appliance 11 (see FIG. 7). Therefore, in both cases, whether the unit body 21 (the unit body 2 on the left in FIG. 3) for front surface mounting is used or the unit body 22 (the unit body 2 on the right in FIG. 3) for back surface mounting is used, the fixing position of the set screw 6 can be determined by using the positioning line 3 that appears in the positioning grooves 4.

[0027] As shown in Fig. 3, the unit body parts 2 are provided with a connecting part 5 that allows the unit body parts 2 to be freely connected to each other in a state in which they are adjacent to each other in the second direction (the left-right direction in Fig. 3). When connecting the unit body parts 2 to each other, the connecting part 5 connects the unit body part 21 for attachment to the front surface part (the unit body part 2 on the left side in Fig. 3) and the unit body part 22 for attachment to the back surface part (the unit body part 2 on the right side in Fig. 3).

[0028] As shown in FIG. 1, the connecting portion 5 is disposed at both ends of the unit body portion 2 in the second direction (left-right direction in FIGS. 1(A), (B) and (D)) over the entire length in the first direction (up-down direction in FIGS. 1(A) and (B)). As shown in FIGS. 1(D) and 4, the connecting portion 5 is provided with a recess 51 and a protrusion 52 arranged adjacent to each other in the thickness direction (front-back direction) of the unit body portion 2, with the recess 51 disposed on the front surface 2a side of the unit body portion 2 and the protrusion 52 disposed on the back surface 2b side of the unit body portion 2. The connecting portion 53 connecting the recess 51 and the protrusion 52 is formed in an inclined shape inclined with respect to the second direction. Incidentally, FIG. 4 shows an enlarged view of the connecting portion 5 in FIG. 3.

[0029] As shown in Fig. 3 and Fig. 4, when the unit body part 21 for mounting on the front surface and the unit body part 22 for mounting on the back surface are connected, the unit body part 22 for mounting on the back surface is reversed with respect to the unit body part 21 for mounting on the front surface, so that the positions of the recessed part 51 and the protruding part 52 in the connecting part 5 are opposite to each other between the unit body part 22 for mounting on the back surface and the unit body part 22 for mounting on the back surface. As a result, the recessed part 51 of the connecting part 5 on the unit body part 21 for mounting on the front surface is engaged with the protruding part 52 of the connecting part 5 on the unit body part 22 for mounting on the back surface, and the protruding part 52 of the connecting part 5 on the unit body part 21 for mounting on the front surface is engaged with the recessed part 51 of the connecting part 5 on the unit body part 22 for mounting on the back surface, thereby connecting the unit body part 21 for mounting on the front surface and the unit body part 22 for mounting on the back surface. In this way, the connecting part 5 is configured as an engaging type connecting part 5.

[0030] Incidentally, when connecting the unit main body part 21 for attachment to the front surface part and the unit main body part 22 for attachment to the back surface part using the connecting part 5, the unit main body part 21 for attachment to the front surface part and the unit main body part 22 for attachment to the back surface part can be fixed in a connected state using the connecting part 5 by nailing or screwing the connecting points, or by applying adhesive to the connecting points in advance, etc.

[0031] 3 shows a case where two unit body parts 2 are connected, but since the connecting parts 5 are disposed at both ends in the second direction of the unit body part 2, it is also possible to connect, for example, three unit body parts 2 by connecting unit body parts 22 for back surface attachment to both sides of one unit body part 21 for front surface attachment. In this way, by changing the number of unit body parts 2 connected by the connecting parts 5 according to the size required for the instrument mounting plate 1, it is possible to change the size of the instrument mounting plate 1, and it is possible to flexibly respond to changes in the required size.

[0032] As shown in Figures 3 and 5, the positioning grooves 4 are formed in the connecting portion 5 at a predetermined constant pitch in the second direction, continuing from the positioning grooves 4 formed in the unit body portion 2. Figure 5 is an enlarged view of the connection portion by the connecting portion 5 in Figure 3. The positioning grooves 4 are formed in the convex portion 52 of the connecting portion 5 at a predetermined constant pitch in the second direction. As a result, even if the fixing position of the setscrew 6 when mounting the electric appliance 11 (see Figure 6) to the appliance mounting plate 1 corresponds to the connecting portion 5, the fixing position of the setscrew 6 can be determined by using the positioning grooves 4 formed in the connecting portion 5.

[0033] As shown in a plan view of an enlarged portion of FIG. 4, the connecting portion 5 is provided with a groove forming portion 7 at an edge portion in the second direction (left-right direction in FIG. 4). When the unit body portion 21 for attachment to the front portion and the unit body portion 22 for attachment to the back portion are connected by the connecting portion 5 in a state in which they are adjacent to each other in the second direction, a positioning groove portion 4 is formed by the groove forming portion 7 at a joint portion 8. The groove forming portion 7 is provided as a notch portion formed by cutting out an edge portion in the second direction of the unit body portion 2 in an inclined manner. When the unit body portion 21 for attachment to the front portion and the unit body portion 22 for attachment to the back portion are connected, a V-shaped positioning groove portion 4 is formed by the groove forming portion 7 of the unit body portion 21 for attachment to the front portion and the groove forming portion 7 of the unit body portion 22 for attachment to the back portion.

[0034] In this way, the positioning grooves 4 are formed at a predetermined constant pitch in the second direction also in the connecting portion 5 and also in the joint regions 8 between the unit body portions 2, so that the positioning grooves 4 are not interrupted even in the connecting portion 5 and the joint regions 8 between the unit body portions, and the positioning grooves 4 can be present at a predetermined constant pitch in the second direction throughout the entirety of the multiple connected unit body portions 2. Therefore, the position at which the set screw 6 is to be positioned can be freely selected, and the efficiency of the positioning operation of the set screw 6 can be improved.

[0035] When mounting an electric appliance 11 on the appliance mounting plate 1, the electric appliance 11 is mounted at a desired position on the appliance mounting plate 1 using a set screw 6, as shown in Fig. 6. In Fig. 6, the appliance mounting plate 1 is made up of two unit body parts 2, a unit body part 21 for mounting on the front side and a unit body part 22 for mounting on the back side. Also, although a case where a watt-hour meter is mounted as the electric appliance 11 is shown, this is merely an example, and various other electric appliances 11 can be mounted.

[0036] In the example shown in Fig. 6, the watt-hour meter as the electric appliance 11 is provided with, for example, a mounting plate 11a and a storage cover 11b covering the front side of the mounting plate 11a, and the watt-hour meter is provided inside the storage cover 11b. The set screw 6 is inserted through the mounting hole 11c of the mounting plate 11a, and the fixing position on the appliance mounting plate 1 is determined using the positioning line 3, and the set screw 6 is fixed to the determined fixing position. The storage cover 11b is attached to the mounting plate 11a attached to the appliance mounting plate 1 in a state in which the watt-hour meter is stored inside. In this manner, the electric appliance 11 is attached to the mounting location 12 via the appliance mounting plate 1.

[0037] Regarding the method of attachment to the attachment location 12, for example, the appliance mounting plate 1 can be attached to the attachment location 12 first, and then the electric appliance 11 can be attached to the appliance mounting plate 1. Conversely, the electric appliance 11 can be attached to the appliance mounting plate 1 first, and then the appliance mounting plate 1 can be attached to the attachment location 12 together with the electric appliance 11.

[0038] Here, regarding the mounting location 12, for example, when mounting in a collective housing such as an apartment building, the mounting location 12 may be inside a pipe shaft in which various pipes are arranged, the space behind the ceiling of the residence, or the inside of an instrument room in which various instruments are installed. Since the use of electrical appliances 11 is required in various construction works, temporary materials such as supports and wall surfaces at temporary construction sites can also be the mounting location 12. Even outdoors, such as in a coin parking lot, the mounting location 12 can be a support or wall surface. In this way, various locations can be applied for the mounting location 12.

[0039] The electrical appliance 11 is not limited to the watt-hour meter shown in Figures 6 and 7, but may be any of a variety of electrical appliances such as high-voltage meters, other meters, switch boxes, fuse boxes, etc. In this case, the number of unit main bodies 2 constituting the appliance mounting plate 1 can be changed depending on the size and number of the electrical appliances 11 to be mounted.

[0040] [Another embodiment] Other embodiments of the present invention will be described below. Note that the configurations of the embodiments described below are not limited to being applied alone, but may also be applied in combination with the configurations of other embodiments.

[0041] (1) In the above embodiment, the connecting portion 5 is configured as an engagement type connecting portion, but this is not limited to the engagement type, and various types can be adopted, such as a type in which the end portions are butted together to connect them, or a fitting type.

[0042] (2) In the above embodiment, the unit main body portion 2 is made of a foamed resin molded product made by foaming a foamed resin material. However, the unit main body portion 2 is not limited to a foamed resin molded product and may be made of a resin product manufactured by other methods, etc. [Explanation of symbols]
