Description

  The present invention relates to an electric device mounting base member used for mounting an electric device such as a remote controller of a water heater or a flat-screen television on a desired wall such as a bathroom or kitchen, and an electric device mounting structure including the same.

  For example, a technique using a stay pipe is often used as a technique for attaching an electric device such as a remote controller of a water heater to a wall of a bathroom (for example, see Patent Document 1). Here, the stay pipe is a pipe that is directly or indirectly connected to an electric device to be attached to a wall and can directly or indirectly support the electric device, and is a wiring of the electric device. Can be passed inside. In the method using the stay pipe, the stay pipe is connected to an electric device, and then inserted into an opening provided on the wall of the bathroom to be fixed, thereby fixing and supporting the electric device. The equipment wiring can be pulled out of the bathroom while being protected by the stay pipe.

  However, in the past, there was room for improvement as described below.

  That is, as schematically shown in FIG. 6, conventionally, the stay pipe 8 is often connected to a case 90 as a base member for mounting the electrical equipment 9. In this connection, the stay pipe 8 is connected to the case. The distal end opening 8a of the stay pipe 8 is disposed in the case 90, for example, through the back plate 90a of the 90. On the other hand, when the electric device 9 is attached to the front side of the case 90, the electric device 9 cannot be disposed in front of the stay pipe 8 and may be biased vertically or horizontally with respect to the stay pipe 8. For example, as shown in the figure, when there are two electrical devices 9, both of the two electrical devices 9 cannot be arranged in front of the stay pipe 8.

  However, in the case where the electric device 9 is arranged so as to be biased with respect to the stay pipe 8 as described above, the electric device 9 is arranged on the front side by an appropriate dimension L1 or more than the tip opening 8a of the stay pipe 8. There is a need. The reason is that it is necessary to secure a space for guiding the wiring 91 connected to the back surface portion of the electrical device 9 into the tip opening 8a of the stay pipe 8, and the above-described dimension L1 is reduced to reduce the space. This is because it is difficult to arrange the wiring 91 in this portion neatly and workability is deteriorated. For this reason, conventionally, it is necessary to increase the volume of the case 90, and the overall size tends to increase. Therefore, there is still room for improvement from the viewpoint of facilitating the routing of the wiring 91 while promoting the downsizing of the entire mounting structure of the electrical device 9. In particular, as shown in the figure, when two electrical devices 9 (for example, a remote controller for a water heater and a flat-screen TV) are attached together, the total number of those wires increases, and the whole is bulky. As the size of the electric wire becomes larger, the handling of the electric wiring becomes more troublesome.

JP 2004-53221 A

The present invention has been conceived under the circumstances as described above, and is intended to reduce the overall size of the mounting structure of a remote controller for a water heater and other desired electrical equipment and improve the workability. It is an object of the present invention to provide an electric device mounting base member that can be used, and an electric device mounting structure including the same.

  In order to solve the above problems, the present invention takes the following technical means.

The electric device mounting base member provided by the first aspect of the present invention is capable of mounting a plurality of electric devices on the front surface side, and is arranged on the wall portion so that the rear surface side faces a desired wall portion.

A plurality of wiring holes for passing wirings of the plurality of electrical devices to the back side of the base member main body , and the stay pipe connecting portion is formed on the back side of the base member main body. A plurality of projections located between the plurality of wiring holes and projecting from the base member main body toward the back thereof, and the stay pipes are provided in the plurality of projections. By providing a screw part for screwing and connecting to the middle part of the plurality of protrusions, there is a gap between the tip part of the stay pipe and the back part of the base member main body part. is formed, and portions between each other said plurality of projections, said being a plurality of openings communicating with said gap and positioned around the gap, the plurality of electric devices of wires, said plurality The portion that is passed through the wiring hole and disposed on the back side of the base member main body is configured to be able to enter the gap through the plurality of openings and pass through the stay pipe. It is characterized by being.

According to such a structure, about the wiring of the several electric equipment attached to the front side of a base member main-body part, after letting it pass the several wiring hole of a base member main-body part, it passes through the said several opening part. By guiding to the gap, it can be properly passed through the stay pipe. When mounting a plurality of electrical devices on the front side of the base member main body, so as to be positioned on the rear side of the base member body wiring of a plurality of electric devices as it passes through the wire hole, a plurality of electric devices May be directly attached to the base member main body, and it is not necessary to secure a space for routing the wiring between the plurality of electric devices and the base member main body. On the other hand, although the stay pipe connecting portion is provided on the back side of the base member main body portion, the stay pipe connecting portion itself does not need to be formed so large. Therefore, as compared with the prior art described with reference to FIG. 6, it is possible to reduce the size of the entire mounting structure of a plurality of electric devices. Further, according to the present invention, all the work of guiding the wiring of the plurality of electric devices into the stay pipe can be performed collectively on the back side of the base member main body, and as in the prior art, the case Compared with the case where a plurality of wires are passed through the stay pipe in the shaped member, the wiring is also facilitated and the workability of the installation work is improved.
Furthermore, according to the said structure, the connection part for stay pipes is implement | achieved by the simple structure using the several projection part which provided the thread part, and it suppresses the complexity of a structure, a big rise in manufacturing cost, etc. This is preferable.
Furthermore, it becomes possible to easily attach a plurality of electric devices using the base member.

  In the present invention, preferably, a rib projecting toward the back of the base member main body is provided between the wiring hole and the stay pipe connecting portion on the back side of the base member main body. The rib is provided with a notch recess for locking a part of the wiring.

  According to such a configuration, a portion of the wiring disposed on the back side of the base member main body portion through the wiring hole is locked and positioned in the notch recess, and when the wiring is routed, This wiring can be prevented from being inadvertently displaced. Moreover, the rib provided with the said notch recessed part also exhibits the role which reinforces a base member main-body part.

An electrical equipment mounting structure provided by the second aspect of the present invention includes a base member attached to a desired wall portion, and a plurality of electrical equipments attached to the front side of the base member. The mounting structure is characterized in that the base member for mounting electrical equipment provided by the first aspect of the present invention is used as the base member.

  According to such a configuration, an effect similar to that described for the electric device mounting base member provided by the first aspect of the present invention can be obtained.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

It is a perspective view which shows an example of the attachment structure of the electric equipment which concerns on this invention. It is II-II sectional drawing of FIG. It is a disassembled perspective view of the attachment structure of the electric equipment shown in FIG. FIG. 2 is an exploded cross-sectional view of a main part of the electric device mounting structure shown in FIG. It is a back perspective view of the base member used for the attachment structure of the electric equipment shown in FIG. It is sectional drawing which shows an example of a prior art typically.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  1 to 5 show an embodiment of an electric equipment mounting structure to which the present invention is applied. As shown well in FIG. 1, the electrical equipment mounting structure S of the present embodiment uses a base member B and a remote control of a TV unit 6A and a water heater (not shown) on a wall portion 7 standing in a bathroom. 6B is attached.

  2 to 4, the television unit 6A includes a television body 60A and a cover body 61A attached to the television body 60A from the front side. Similarly, the remote controller 6B includes a remote controller main body 60B and a cover body 61B attached to the remote controller main body 60B from the front side. As the television unit 6A and the remote controller 6B, known ones can be used as appropriate, and the description thereof is omitted.

  The base member B corresponds to an example of an electric equipment mounting base member to which the present invention is applied. The base member B is made of a synthetic resin which is relatively hard as a whole, and has a substantially rectangular base member main body 1 in front view, and a back surface thereof. It has the connecting part 2 for stay pipes provided. As shown in FIG. 3, the base member main body 1 has a plate-like portion 10 having a flat front surface, and two wiring holes 11 are formed vertically on the plate-like portion 10. It is provided at intervals. These wiring holes 11 are for passing the wirings 62A and 62B of the TV unit 6A and the remote control 6B to the back side of the base member main body 1.

  A plurality of screw holes 12 are provided on the peripheral edge of the base member main body 1. The television body 60A and the remote control body 60B can be fixed to the front side of the base member body 1 by using the screw body 99 screwed into the screw hole 12. The cover bodies 61A and 61B are attached to the television body 60A and the remote controller body 60B after they are attached to the base member B. As shown in FIG. 2 and FIG. 4, a seal member 63 made of a loop-like elastic member that surrounds the bases of the wirings 62A and 62B is attached to the back surfaces of the TV main body 60A and the remote control main body 60B. Yes. When the seal member 63 comes into contact with the plate-like portion 10 of the base member B, a water-stop seal of this portion is achieved. As a result, even if water enters between the TV main body 60A and the base member main body 1 or between the remote control main body 60B and the base member main body 1, this water is the base of the wirings 62A and 62B. Proceeding toward is properly prevented.

  The stay pipe connecting portion 2 is configured by integrally forming a pair of projecting portions 20 on the back surface portion of the base member main body portion 1. As clearly shown in FIG. 5, the pair of projections 20 are opposed to each other with a pair of slit-like gaps 21 therebetween, and the cylindrical projection is divided into left and right parts. It is the same composition as. A screw portion 22 for screwing a screw portion 50 on the outer periphery of the distal end portion of the stay pipe 5 is provided on the inner peripheral surfaces of the pair of protrusions 20. However, the screw portion 22 is provided only in the range of the middle height from the tip side of each projection portion 20, and is not provided in the vicinity of the base portion of each projection portion 20. As a result, as shown in FIG. 2, when the screw portion 50 of the stay pipe 5 is screwed into the screw portion 22, the distal end portion of the stay pipe 5 does not advance to the proximal end of each projection portion 20. A gap 30 is formed between the tip of the stay pipe 5 and the back surface of the base member main body 1. The gap 30 is a portion that allows the wires 62A and 62B to enter the tip opening without closing the tip opening of the stay pipe 5. As a means for forming the gap 30, instead of providing the screw portion 22 to a midway height, for example, when the tip of the stay pipe 5 has advanced to a midway height of each projection 20, the stay pipe 5 A means for providing a stopper (not shown) in contact with the base member main body 1 may be employed.

  As shown in FIG. 2, when the stay pipe 5 is connected to the stay pipe connecting portion 2, two openings 21 a that allow the gap 30 to communicate with the external space are formed. These openings 21a are a part of the two slit-like gaps 21 shown in FIG. 5 (a part of the gap 21 that is not closed by the stay pipe 5). The wirings 62A and 62B pass through the two wiring holes 11 and are arranged on the back side of the base member main body 1. The wirings 62A and 62B pass through the opening 21a and enter the gap 30. After entering, the state is set to be passed through the stay pipe 5. In the assembly procedure of the electrical equipment mounting structure S, it is not necessary to pass the wires 62A and 62B through the stay pipe 5 after the stay pipe 5 is connected to the stay pipe connecting portion 2. It goes without saying that the stay pipe 5 may be connected to the stay pipe connecting portion 2 after the wires 62A and 62B have been passed through the stay pipe 5 first. The stay pipe 5 is inserted and fixed in a hole 70 provided in the wall 7 of the bathroom. The wires 62A and 62B pass through the stay pipe 5 and are drawn out of the bathroom.

As clearly shown in FIG. 5, on the back side of the base member main body 1, a frame-shaped convex portion 13 having a rectangular loop-shaped sealing member 80 attached thereto, reinforcing ribs 14 and 15, and ribs 15. Are provided with a plurality of notch recesses 16 and a flange 4 serving also as a reinforcing rib.

  The frame-shaped convex part 13 protrudes toward the back from the outer peripheral edge part of the plate-shaped part 10 so that it may appear well in FIG. 2 and FIG. When the base member B is attached to the wall portion 7, the seal member 80 is sandwiched between the frame-shaped convex portion 13 and the wall portion 7, and a water sealing is achieved. This suppresses water from entering between the wall portion 7 and the base member B. The frame-shaped convex portion 13 and the seal member 80 are provided with screw body insertion holes 19 for enabling the base member B to be screwed to the wall portion 7. If such a screwing means is provided, the mounting strength of the base member B can be made higher than when the base member B is fixed using only the stay pipe 5, and the stay pipe 5 is not used. Mounting is also possible, providing excellent flexibility.

  The reinforcing rib 14 is located between the pair of protrusions 20 and has a form extending in a direction in which the pair of protrusions 20 face each other. The stay pipe connecting portion 2 and its peripheral portion may receive a relatively large force from the stay pipe 5, but the presence of the ribs 14 can efficiently reinforce those portions.

  As the ribs 15, there are a plurality of vertical ribs extending in the vertical direction and a plurality of horizontal ribs extending in the left and right substantially horizontal directions, and these are crossed and connected. According to such a structure, the wide area of the base member main-body part 1 can be reinforced efficiently. The plurality of ribs 15 include two ribs 15 a located between the wiring hole 11 and the stay pipe connecting portion 2, and a notch recess 16 is provided in these ribs 15 a. As shown in FIG. 2, the notch recess 16 is a portion for allowing a part of the wirings 62 </ b> A and 62 </ b> B to enter and be locked. This makes it possible to position the wirings 62A and 62B when the mounting structure S is assembled.

  Even if water enters between the upper part of the base member main body 1 and the wall 7, the flange 4 is a part for appropriately dealing with this. The flange 4 is located near the upper portion of the base member main body 1 so as to be positioned above the two wiring holes 11 and the stay pipe connecting portion 2, and is similar to the reinforcing ribs 14 and 15. The rib shape protrudes toward the back of the base member main body 1. As shown in FIG. 2, the height H <b> 1 of the flange portion 4 is preferably a height at which the tip of the flange portion 4 comes into contact with or approaches the wall portion 7. When water enters between the wall portion 7, the water can be received by the upper surface 40. Although the height H1 of the collar part 4 is so preferable that it is so high that the clearance gap between the collar part 4 and the wall part 7 becomes small, the specific value is not ask | required. However, it is desirable that the height H1 of the collar portion 4 is higher than at least the height H2 of the gap 30. If H1> H2, the upper part of the wirings 62A and 62B that are not inserted into the stay pipe 5 is appropriately covered with the flange part 4, and water can be prevented from flowing directly to the part. It is.

  As shown in FIG. 5, the collar portion 4 is inclined in a substantially square shape so that the substantially central portion 4a in the left-right width direction is the highest and the height gradually decreases as it goes to the width direction both end portions 4b. It has a form. Thereby, the water received by the upper surface 40 of the collar part 4 flows toward both or one side of the both ends 4b, as shown by the arrow N1. Both end portions 4b of the flange portion 4 are located on the outer side in the left-right width direction of the base member B with respect to the plurality of reinforcing ribs 15, and the water that has reached the both end portions 4b is indicated by an arrow N2. It passes through the outer side of the outermost vertical rib 15b and falls onto the receiving part 17 located near the lower part of the base member main body part 1.

The receiving portion 17 is constituted by a part of the frame-like convex portion 13 and is connected to intersect with the lower edge portion of the plate-like portion 10. A pair of drainage holes 18 are provided at both ends in the width direction of the lower edge of the plate-like portion 10. Preferably, similarly to the flange portion 4, the receiving portion 17 is inclined so that the height gradually decreases as it proceeds from the substantially central portion in the left-right width direction to both end portions, and is received by the receiving portion 17. Water is configured to smoothly flow into the drain hole 18. As shown by an arrow N3 in FIG. 2, the water received by the receiving portion 17 passes through the drainage hole 18 and flows to the front side of the base member main body portion 1, and then below the base member main body portion 1. It is supposed to flow down. Preferably, the upper surface of the receiving portion 17 is inclined in a front-down manner, so that the water flows into the hole portion 18 more smoothly. As shown in FIG. 2, the remote controller 6 </ b> B is disposed so as to cover the front surface of the hole 18 while being provided so as not to close the hole 18. In this way, if the front surface of the hole 18 is covered by the remote controller 6B, the risk of water entering the hole 18 from the front surface can be eliminated or reduced.

  Next, the operation of the electrical equipment mounting structure S described above will be described.

  First, the wires 62A and 62B of the TV unit 6A and the remote controller 6B of the water heater are passed through the two wiring holes 11 to the back side of the base member B and enter the gap 30 through the opening 21a, so that the stay pipe 5 can be set appropriately. The TV unit 6A and the remote control 6B may be attached by contacting or approaching the front surface of the base member B so that the bases of the wirings 62A and 62B face the wiring holes 11. By changing the position of the wiring hole 11, the arrangement of the TV unit 6A and the remote controller 6B can be freely changed. In addition, unlike the prior art, it is not necessary to provide a space for guiding the wires 62A and 62B into the stay pipe 5 between the TV unit 6A or the remote controller 6B and the base member B. Therefore, it is possible to appropriately avoid the television unit 6A and the remote controller 6B being provided in a large and bulky state on the front side of the base member B.

  On the other hand, although the stay pipe connecting portion 2 is provided on the back side of the base member B, the stay pipe connecting portion 2 itself is configured by using a pair of protrusions 20, The height of the reinforcing rib 15 can be a small size equal to or lower than the height of the reinforcing rib 15 or the like. Therefore, although the structure on the back side of the base member B is somewhat complicated, the entire electrical equipment mounting structure S is based on the fact that it is not necessary to provide a space for arranging the wirings 62A and 62B on the front side of the base member B. It is possible to reduce the size.

  The operation of passing the wires 62A and 62B through the stay pipe 5 can be performed collectively on the back side of the base member B. Therefore, the work becomes easy. In particular, in the present embodiment, the wirings 62A and 62B are locked to the notch recess 16, so that the wirings 62A and 62B can be prevented from inadvertently moving when the wirings 62A and 62B are routed. , The operation is made easier. The notch recess 16 is rational because it is provided using the reinforcing rib 15a of the base member B. Further, since the base member B is also provided with the ribs 14 and the flange portion 4 that exhibits a reinforcing function, it is possible to ensure sufficient strength while reducing the thickness of each part of the base member B. .

In the present embodiment, the water stop seal using the seal members 63 and 80 prevents water from entering a predetermined portion, thereby appropriately protecting the electric system. When the seal member 80 is deteriorated or the surface of the wall 7 is tiled and the joint portion of the tile has a deep concave shape, the upper part of the base member B and the wall 7 During this period, water can enter, but as described below, such a situation can be appropriately dealt with. That is, as indicated by arrows N1 to N3 in FIGS. 5 and 2, the water described above is received by the flange 4 and then guided toward the end 4b and flows down from the end 4b, and thereafter Is received by the receiving part 17, passes through the drain hole 18, and is discharged below the base member B. Therefore, the wirings 62A and 62B are more thoroughly prevented from getting wet. Moreover, it is also avoided appropriately that much water accumulates in the lower part of the base member B. Furthermore, if water is dropped and discharged from the front surface side of the base member B, unlike the case where water is discharged along the surface of the wall portion 7, the effect of making it difficult for water stains to occur on the surface of the wall portion 7 is also achieved. I can expect.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the electric device mounting base member and the electric device mounting structure according to the present invention can be varied in design in various ways.

  The electric device mounting base member of the present invention is suitable for attaching a plurality of electric devices to the wall portion together, but is not limited to this, and is also applicable to, for example, mounting one electric device to the wall portion. Is possible. Even when one electric device is attached to the wall, the wiring base of the electric device cannot be arranged in front of the stay pipe, depending on the construction conditions, and the wiring base and the stay pipe In some cases, the present invention is significant.

  As a connecting structure between the stay pipe connecting portion and the stay pipe, an engaging means that does not use the screw portion may be used instead of the screwing means using the screw portion. As an example, there is a system in which the stay pipe is inserted into a recess formed as a stay pipe connecting portion and rotated by an appropriate angle so that the both engage and connect.

  As the electric device, various devices other than the television unit and the remote controller of the water heater can be applied. Needless to say, the wall part to which the electric device is attached is not limited to the wall part of the bathroom, but can be a wall part of a kitchen or other various rooms or places.
