Description

The present invention relates to a wiring box having a storage portion for storing wiring equipment such as an outlet and a switch, and being attached to a stud provided in a building structure such as a house.

The wiring box as described above includes a box body in which the box opening opens to the front, and a contact portion that comes into contact with the wall portion of the lightweight steel material (stud) is provided on the left wall of the box body. In addition, there is a case in which a protrusion extending to the left outer side of the box body and having a back surface located substantially on the same plane as the opening surface of the box opening is provided on the box opening side of the contact portion. (See, for example, Patent Document 1).

When the above wiring box is attached to the lightweight steel material, the contact portion is brought into contact with the wall portion (lip portion) of the lightweight shaped steel material, and the back surface of the protruding portion is brought into contact with the side plate portion of the lightweight shaped steel material. As a result, the positions of the wiring box in the front-rear direction and the left-right direction with respect to the lightweight shaped steel material can be appropriately positioned. Then, if the protruding portion of the wiring box positioned in this way is sandwiched between the thumb of the hand that grips the lightweight shaped steel material from the back plate portion side and the side plate portion of the lightweight shaped steel material, the lightweight shaped steel material can be used. The protruding part of the wiring box can be grasped by hand together with the lightweight shaped steel while maintaining the positioning state. Then, in the state of being grasped in this way, by screwing the left side wall of the box body to the wall portion of the lightweight steel material, the opening surface of the wiring box is positioned on substantially the same plane as the outer wall surface of the side plate portion. It can be fixed to a lightweight shaped steel material in the state. Then, after this fixing, the wall material can be fixed to the side plate portion of the lightweight shaped steel material by separating the protruding portion from the box body using a screwdriver or pliers.

Japanese Patent No. 4138829

In the wiring box described in Patent Document 1, the left side wall of the box body is screwed to the wall portion of the lightweight steel material. Therefore, when this screwing work is performed, the right side wall facing the left side wall of the box body is used. Becomes an obstacle and makes it difficult to perform screwing work. In particular, since the wiring box is positioned and held with respect to the lightweight shaped steel material with one hand, the screwing work with the other hand is hindered by the right wall of the box body, and the posture of the screw with respect to the left wall becomes unstable. However, since the posture of the screw cannot be stabilized with one hand, it may take time to screw the box body to the lightweight shaped steel material.

Further, the protrusion is only for allowing one hand to position and hold the wiring box with respect to the lightweight steel material, and after the box body is screwed to the lightweight steel material, it is separated from the box body and is a waste material. As the number of wiring boxes provided in building structures such as houses increases, the number of protrusions to be treated as waste materials also increases, and the time and effort required for disposal also increases.

In view of this situation, a main problem of the present invention is to make it easier to properly attach the wiring box to the studs while eliminating the trouble of disposing the positioning portion of the wiring box to the studs as a waste material.

The first characteristic configuration of the present invention is in a wiring box.
A box-shaped box body having an open front surface and a connecting body connected to one left and right side surface of a stud are connected to each other via a separating portion that enables the box body and the connecting body to be separated from each other. It is integrally formed in a shape extending vertically or substantially vertically from one end surface of the box body toward the outside.
An engaging portion that enables engaging connection with the connecting body is formed on either the left or right side plate of the box body.
One end of the box body pressed against the left and right side surfaces of the stud in a state of being positioned in the front-rear direction with respect to the stud when the one end surface of the box body is pressed against the front surface of the stud. The engaging portion is located on the opposite side of the one end portion and the connecting portion connected to the left and right one side surface of the stud in a positioned state by the one end surface and the one end portion with respect to the stud. Is provided with an engaged portion to which the studs are engaged and connected.
The box body is separated from the connecting body connected to the left and right side surfaces of the studs, and in a state where the engaging portion is engaged and connected to the engaged portion, the front end surface of the box body and the box body are described. The point is that the front surface of the stud is set to be flush with or substantially flush with the front surface.

According to this configuration, when the wiring box is attached to one left and right side surface of the stud, one end surface of the box body to which the connecting body is connected is pressed against the front surface of the stud to make surface contact, and one end portion of the connecting body is brought into surface contact. Press against the left and right sides of the studs to bring them into contact. As a result, the wiring box can be easily and stably positioned with respect to the studs in a state where the positions of the connecting body in the front-rear direction and the left-right direction with respect to one side surface of the studs are appropriate. Then, while holding the wiring box positioned in this way in the positioned state with one hand, the connecting body is connected to one left and right side surface of the stud with the other hand, whereby the connecting body is connected to the stud. It can be easily fixed at an appropriate position in the front-rear direction and the left-right direction with respect to one left and right side surface. Then, after this fixing, the box body is separated from the connecting body and the engaging portion of the box body is engaged with the engaged portion of the connecting body, so that the front end surface of the box body and the front surface of the stud are flush with each other. The box body can be easily attached to the left and right sides of the studs via a connecting body in an appropriate state of being substantially flush with each other. As a result, when a wall material such as gypsum board is attached to the front surface of the studs, the attachment can be performed satisfactorily without being hindered by the front end surface of the box body.

That is, in this configuration, one end surface of the box body is used as a positioning surface for positioning the connecting body in the front-rear direction with respect to one left and right side surface of the stud, and the positioned connecting body is used on the left and right sides of the stud with a connecting tool. Since it is connected to the side surface, for example, when the side plate of the box body is connected to one left and right side surface of the stud with a connecting tool, the side plate on the opposite side facing the side plate on the connecting side in the box body becomes an obstacle. There is no inconvenience such as difficulty in connecting with a connecting tool.

Then, after connecting the connecting body to one left and right side surface of the stud, the box body used for positioning is separated from the connecting body, and the separated box body is engaged and connected to the connecting body and attached to one left and right side surface of the stud. For example, when the wiring box is provided with a dedicated positioning unit for positioning the box body in the front-rear direction with respect to the studs, after the box body is attached to the studs, the dedicated positioning unit is separated from the box body and used as waste material. No need to process.

As a result, it is possible to further facilitate proper attachment of the wiring box to the studs while eliminating the trouble of treating the positioning portion of the wiring box with respect to the studs as waste material.

The second characteristic configuration of the present invention is
The connecting body is formed in a plate shape extending outward from one end surface having the same or substantially the same extension length as the front-rear width of either the left or right side plate on which the engaging portion is formed. There is a point.

According to this configuration, it is possible to widen the contact area when one end of the connecting body is pressed against one left and right side surface of the stud and brought into contact with each other. As a result, the positioning state of the wiring box with respect to the studs in which one end surface of the box body is brought into surface contact with the front surface of the studs and one end portion of the connecting body is brought into contact with the left and right side surfaces of the studs is more stably maintained. Can be done. Therefore, it is possible to more easily connect the connecting body to the left and right side surfaces of the studs by the connecting tool.

Further, when the engaging portion of the box body is engagedly connected to the engaged portion of the connecting body, the contact area between the side plate of the box body and the connecting body can be widened. As a result, the side plates of the box body can be engaged and connected to the connecting body with better stability.

As a result, the box body can be properly attached to the studs in a more stable state while being attached to the left and right sides of the studs via a connecting body.

The third characteristic configuration of the present invention is
The engaged portion and the engaged portion include a guide portion that slides and guides the box body between the front surface side and the rear surface side of the stud, and the engaged portion is engaged with the engaged portion. A regulating portion that regulates the sliding movement of the box body to the rear surface side and a retaining portion that prevents the sliding movement of the box body from the engaging connection position to the front surface side are provided. There is a point.

According to this configuration, when the box body separated from the connecting body is engaged and connected to the connecting body connected to one left and right side surface of the stud, the box body is connected from the front side to the rear surface side of the stud according to the guide portion. When the sliding movement of the box body reaches the engaging connection position with the engaged part of the connecting body, the sliding movement to the rear surface side of the box body is restricted by the regulating part. , The sliding movement from the engaging connection position of the box body to the front side is blocked by the retaining portion.

That is, simply by sliding the box body from the front side to the rear side of the stud according to the guide portion with respect to the connecting body connected to the left and right sides of the stud, the box body can be pulled out to an appropriate position with respect to the left and right sides of the stud. Can be installed in a stopped state.

As a result, the proper attachment of the wiring box to the studs can be further facilitated.

The fourth characteristic configuration of the present invention is
At the end of the connecting body on the box body side, there is a matching mark that enables alignment with the mark marked on the front surface of the stud so as to indicate the mounting height position of the box body with respect to the stud. Formed,
An opening is formed between the box body and the connecting body to enable visual alignment of the alignment mark with respect to the mark.

According to this configuration, when positioning the connecting body with respect to one left and right side surface of the stud, the mark of the stud and the matching mark of the box body can be visually observed from the opening between the box body and the connecting body. They can be easily aligned. As a result, in the positioning state of the wiring box with respect to the studs in which one end surface of the box body is brought into surface contact with the front surface of the studs and one end portion of the connecting body is brought into contact with one left and right side surface of the studs, the height of the connecting body with respect to the studs is high. The stud position can also be properly positioned. As a result, the height position with respect to the studs of the box body engaged and connected to the connecting body can also be adjusted appropriately.

That is, since the positioning of the connecting body with respect to one left and right side surface of the stud can be easily and appropriately performed in the height direction in addition to the front-rear direction and the left-right direction with respect to the stud, the wiring box can be attached to the stud more easily and appropriately. Can be done.

The fifth characteristic configuration of the present invention is
The connecting body extends outward from the outer end surface of the side plate on which the engaging portion is formed.
In the state where the box body is separated from the connecting body, the separation position is set so that the separating portion remains on the connecting body side.

For example, if the separating portion remains on the box body side in a state where the box body is separated from the connecting body, the separating portion is located on the outer end surface of the side plate on which the engaging portion is formed in the box body. Then, when the engaging portion of the box body separated from the connecting body is engaged and connected to the engaged portion of the connecting body, the engaging connection may be hindered by the separating portion remaining on the outer end surface of the side plate. , It is necessary to add a configuration to avoid this inhibition.

On the other hand, according to this configuration, when the box body is separated from the connecting body and the engaging portion of the box body is engaged and connected to the engaged portion of the connecting body, the side plate on which the engaging portion is formed is formed. Since the separating portion does not remain on the outer end surface of the above, it is possible to avoid the possibility that the engaging portion is hindered by the separating portion.

That is, the possibility that the engaging connection of the engaging portion with respect to the engaged portion is hindered by the separating portion can be avoided without incurring the complexity of the configuration by adding the configuration for avoiding the hindrance.

It has a recess 33Cb.

At the front end, which is the end on the box body 10 side of the connecting body 30 connected to the right side surface 1A of the stud 1, the front surface 1B of the stud 1 indicates the mounting height position of the box body 10 with respect to the stud 1. A stud 34 is formed that enables alignment with the mark 1C marked with (see FIG. 3). The mark 1C marked on the front surface 1B of the stud 1 is a mounting reference line drawn horizontally on the front surface 1B of the stud 1 so as to indicate the mounting height position of the upper and lower center points of the box body 10 with respect to the stud 1. (See FIGS. 2-3 and 7). The alignment mark 34 of the connecting body 30 is a ridge extending to the left and right at the upper and lower center points of the front end portion of the connecting body 30 (see FIGS. 2, 5, and 7). An opening 41 is formed between the box body 10 and the connecting body 30 in the wiring box A to enable visual alignment of the alignment mark 34 with respect to the mark 1C (see FIG. 3). The opening 41 has a function as a space that allows the box body 10 to be bent toward the connecting body 30 with respect to the connecting body 30, and enables the box main body 10 to be separated from the connecting body 30 by this bending.

The connecting portion 32 is formed with a first through hole 32A for connecting to the stud 1 made of lightweight steel and a second through hole 32B for connecting to the wooden stud 1. The through holes 32A and 32B are subjected to countersunk processing to prevent the countersunk screws 2 from protruding.

Each separating portion 40 has a substantially triangular shape in a plan view in which the front-rear width (front-rear width based on the front-rear direction of the box body 10) becomes wider toward the connecting body 30 side and the front-rear width becomes narrower toward the box body 10 side. (See FIG. 4). As a result, in the wiring box A, when the box body 10 is separated from the connecting body 30 (see FIGS. 5 to 7), the separation position 42 (FIG. 1) so that each separating portion 40 remains on the connecting body 30 side. , See FIG. 4) is set.

Between the connecting portion 32 of the connecting body 30 and the upper and lower separating portions 40, each outer end surface 14A of the left side plate 14 of the box body 10 is in surface contact with the front surface 1B of the stud 1, and the contact surface of the connecting body 30. Upper and lower engaging claws 35 that engage the bent portion 1D between the right side surface 1A and the front surface 1B of the stud 1 in the positioning state of the wiring box A with respect to the stud 1 in which 31 is in surface contact with the right side surface 1A of the stud 1. Is formed (see FIGS. 1, 3-5, 7).

The box body 10 is separated from the connecting body 30 connected to the right side surface 1A of the stud 1, and each engaging portion 21 is engagedly connected to each engaged portion 33 of the connecting body 30 (see FIG. 7). ), The front end surface 10A of the box body 10 and the front surface 1B of the stud 1 are set to be flush with each other or substantially flush with each other.

With the above configuration, when mounting the wiring box A on the right side surface 1A of the stud 1, first, a mark (mounting reference line) 2C indicating the mounting height position of the box body 10 with respect to the stud 1 is placed on the front surface 1B of the stud 1. (See FIG. 2). Next, each outer end surface 14A of the left side plate 14 of the box body 10 is pressed against the front surface 1B of the stud 1 to make surface contact, and the contact surface 31 of the connecting body 30 is pressed against the right side surface 1A of the stud 1 to make surface contact. (See FIGS. 3 and 4). As a result, the wiring box A can be easily and stably positioned with respect to the stud 1 in a state where the positions of the connecting body 30 with respect to the stud 1 in the front-rear direction and the left-right direction are appropriate. Since the connecting body 30 is formed in a plate shape having the same or substantially the same extending length as the front-rear width of the left side plate 14 in the box body 10, the contact surface 31 of the connecting body 30 is on the right side of the stud 1. The contact area when contacted with the surface 1A can be increased. As a result, the connecting body 30 of the wiring box A can be positioned more stably with respect to the right side surface 1A of the stud 1. At this time, the mark 1C of the stud 1 and the alignment mark 34 of the box body 10 can be visually recognized from the opening 41 between the box body 10 and the connecting body 30, and their alignment can be easily performed. (See Fig. 3). As a result, in the positioning state of the wiring box A with respect to the stud 1, the height position of the connecting body 30 with respect to the stud 1 can also be appropriately positioned.

Then, while holding the connected body 30 positioned in this way in the positioned state with one hand, a countersunk screw is used with the other hand on the right side surface 1A of the stud 1 using the first through hole 32A of the connected body 30. Connect at 2. As a result, the connecting body 30 can be easily fixed at an appropriate position with respect to the right side surface 1A of the stud 1. Further, by connecting the connecting body 30 to the right side surface 1A of the stud 1 with the countersunk screw 2, for example, the left plate 14 of the box body 10 is connected to the right side surface 1A of the stud 1 with the countersunk screw 2. In addition, the connecting body 30 is easily fixed to the right side surface 1A of the stud 1 without causing the inconvenience that the right side plate 13 of the box body 10 becomes an obstacle and it becomes difficult to connect the left side plate 14 with the countersunk screws 2. be able to.

After this fixing, when the box body 10 is bent toward the connecting body 30 with respect to the connecting body 30, the box main body 10 is easily separated from the connecting body 30 with each separating portion 40 left at the front end of the connecting body 30. Can be done (see FIGS. 4-5). As a result, each separating portion 40 does not remain on the outer end surface 14A of the left side plate 14 on which the engaging portion 21 is formed in the box body 10, so that the engaging portion 21 of the connecting body 30 with respect to the engaged portion 33 It is possible to avoid the possibility that the engagement connection is hindered by each separation portion 40.
