Description

[Technical Field]

[0001] The present disclosure relates to a fastener that is secured to a wall stud. [Background technology]

[0002] Generally, studs are used to form partitions within buildings. A stud is hollow, with a long slit-shaped opening in the vertical direction formed on one side, and a hook portion that protrudes inward from the edge of the opening is formed along the edge of the opening.

[0003] Wiring boxes and the like are sometimes fixed to partition walls. For example, Patent Document 1 discloses a fixing bracket for fixing a wiring box to a partition wall. The fixing bracket in Patent Document 1 has, as a stud fixing portion that is fixed to the partition wall, a connecting plate that is placed on the outside of the partition wall and a clamping plate that is inserted into the interior of the partition wall through an opening in the partition wall. The clamping plate is formed with a fitting portion that fits into the hook portion from the inside of the partition wall. With the fitting portion fitted into the hook portion, the connecting plate and the clamping plate are fastened with screws to clamp the hook portion inward and outward from the partition wall, thereby fixing the fixing bracket to the partition wall. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4025603 Summary of the Invention [Problem to be solved by the invention]

[0005] However, there are multiple types of stud hooks with different dimensions, including those with narrow and wide hooks. In the case of the fastening fixture described in Patent Document 1, the fitting portion of the clamping plate is fitted to the hook portion from the inside of the stud. Therefore, if the fitting portion is designed to be wide to accommodate a wide hook, it cannot be fitted to a narrow hook. Conversely, if the fitting portion is designed to be narrow to accommodate a narrow hook, play will occur between the hook and fitting portion when fitting to a wide hook. If play occurs, when the connecting plate and clamping plate are fastened with screws, the connecting plate and clamping plate will tilt in the direction of the screw rotation, making it difficult to position the fastening fixture. In short, in the case of the fastening fixture described in Patent Document 1, it is necessary to manufacture dedicated fittings for narrow hooks and dedicated fittings for wide hooks, which increases the variety of fastening fixtures and results in higher costs.

[0006] The present disclosure has been made in consideration of the above points, and its purpose is to provide a fixing bracket that can be fixed in a predetermined position to each of a plurality of types of studs having different hook portion widths. [Means for solving the problem]

[0007] To achieve the above object, one aspect of the present disclosure can be based on a fixing bracket that is fixed to a partition wall having a vertically extending slit-shaped opening formed on one side thereof and a hook portion formed thereon. The fixing bracket is inserted into the partition wall through the opening in the partition wall and has an inner plate that abuts against the hook portion from the inside of the partition wall, and includes a first member that includes: a first support plate that is located on one widthwise end of the inner plate and protrudes toward the base end of the hook portion; a second support plate that is located on the other widthwise end of the inner plate on the opening side of the partition wall and protrudes outward from the opening; and a protrusion that protrudes toward the base end of the hook portion from an intermediate portion of the widthwise inner plate; a second member that has an outer plate that abuts against one side of the partition wall from the outside of the partition wall; and a fastening member that screw-fastens the first member and the second member inward and outward directions of the partition wall.

[0008] According to this configuration, when fixing the fixing bracket to a stud, the first and second members are left unfastened. The inner plate portion of the first member is inserted through the opening in the stud and abuts against the hook portion of the stud, while the second member is abutted against one side of the stud from the outside. Then, by fastening the first and second members together with the fastening member, the first support plate portion, the second support plate, and the outer plate portion of the inner plate portion clamp the hook portion of the stud, thereby fixing the fixing bracket to the stud. In other words, as a reaction force to the tightening force of the fastening member, the first support plate portion abuts against the inner surface of the hook portion, and the end face of the second support plate abuts against the outer plate portion, thereby horizontally attaching the fixing bracket to the hook portion. It is not necessary for the first support plate portion to abut against the inner surface of the hook portion. For example, if the protruding plate portion is longer than the protruding length of the first support plate portion, the protruding plate portion will abut against the inner plate portion.

[0009] In this case, the protrusion of the first component is formed at the widthwise intermediate portion of the inner plate component, and the protrusion of the inner plate component is positioned so as to abut against the inside or outside of the hook component depending on the width or length of the hook component, so that when the stud hook component is wide, the protrusion engages with the tip of the hook component from the inside, thereby positioning the fixing device; conversely, when the stud hook component is narrow, the protrusion engages with the tip of the hook component from the outside, thereby positioning the fixing device. In other words, by forming a protrusion that protrudes toward the base end of the stud hook component at the widthwise intermediate portion of the first component, the fixing device can be fixed in a positioned state relative to the stud without tilting in the direction of rotation of the fastening member during fastening, whether the hook component is wide or narrow, making it possible to fix one type of fixing device to multiple types of studs.

[0010] Furthermore, an abutment plate portion can be formed on the edge of the inner plate portion, extending in the direction in which the hook portion projects along the inner surface of the stud and coming into contact with the inner surface of the stud.

[0011] According to this configuration, the fixing bracket can be stabilized by bringing the contact plate portion of the first member into contact with the inner surface of the stud.

[0012] The inner plate portion may be formed with a pair of upper and lower guide portions for guiding the outer plate portion of the second member to a predetermined position.

[0013] With this configuration, when fastening the second member, the outer plate portion of the second member can be easily guided to a predetermined position between the upper guide portion and the lower guide portion, and because the outer plate portion is restrained from the top and bottom directions, the inner plate portion and the outer plate portion can be attached in a state where they are parallel in the width direction, and can be stably clamped to the hook portion of the partition post.

[0014] Furthermore, a connecting portion that connects the second support plate portion of the inner plate portion to the outer plate portion can be formed.

[0015] With this configuration, the outer plate portion is connected to the inner plate portion with a connecting portion, and the two are loosely fastened together with a fastening member, so that the first and second members can be attached to the hook portion of the partition wall in a pre-assembled, integrated state, eliminating the risk of the members falling off and reducing the hassle of installation. [Effects of the Invention]

[0016] As explained above, the first support plate portion is positioned inside the hook portion at one widthwise end of the inner plate portion that abuts against the hook portion of the partition from the inside and protrudes toward the base end of the hook portion, and the second support plate portion is positioned on the opening side of the partition at the other widthwise end and protrudes outward from the opening, and a protrusion is formed in the middle widthwise portion, so that the fixing bracket can be fixed in a predetermined position to multiple types of partition studs with hook portions of different widths.

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0019] FIG. 1 is a perspective view showing a state in which a box B is fixed to a stud 100 using a fixing bracket 1 according to an embodiment of the present invention. Box B is a box to which, for example, a switch or an outlet is fixed. The structure and shape of box B are not limited to those shown in the figure and may have any structure or shape. Furthermore, a member other than box B may be fixed to the stud 100 using fixing bracket 1.

[0020] Before describing the fixing bracket 1, we will first explain the stud 100. The stud 100 is a component used to form a partition inside a building (not shown), and extends vertically while being installed in multiples at intervals horizontally. As shown in Figure 2, each stud 100 is a hollow component with a roughly rectangular cross section, i.e., a rectangular tubular component.

[0021] Because the partition 100 is composed of a rectangular cylindrical member, the partition 100 has four side surfaces 101, 102, 103, and 104. The width and depth directions of the partition 100 are defined as shown in each drawing, but this definition is for ease of explanation. According to this definition, the side surfaces 102 and 104 extend in the depth direction from both widthwise edges of the side surface 101. Furthermore, the side surfaces 101 and 103 extend in the width direction of the partition 100 and are parallel to each other, and the side surfaces 102 and 104 extend in the depth direction of the partition 100 and are parallel to each other.

[0022] Of the four side surfaces 101, 102, 103, and 104, side surface 101 corresponds to one side surface of the present invention. The width direction of one side surface 101 coincides with the width direction of the partition wall 100. One side surface 101 has a slit-shaped opening 101a that extends in the vertical direction. The width of opening 101a is the same from the top end to the bottom end.

[0023] As shown in Figure 2, a hook portion 101b is formed on each edge of the opening 101a on one side surface 101. The hook portion 101b has a base portion 101c that extends in the width direction of the stud 100 and also in the vertical direction, and a protruding plate portion 101d that protrudes from the edge of the base portion 101c toward the inside of the stud 100. The protruding direction of the protruding plate portion 101d coincides with the depth direction of the stud 100.

[0024] The hook portion 101b is available in two types: wide (shown by a solid line in FIG. 2) and narrow (shown by a virtual line in FIG. 2). The width of the hook portion 101b is the width of the base portion 101c. That is, the hook portion 101b with a wide base portion 101c is the wide hook portion 101b, and the hook portion 101b with a narrow base portion 101c is the narrow hook portion 101b. There are studs 100 with wide hook portions 101b and studs 100 with narrow hook portions 101b, and in this embodiment, the same fastener 1 can be used to fasten the box B to either type of stud 100.

[0025] Next, the structure of the fixing bracket 1 that is fixed to the stud 100 configured as described above will be described in detail. Fig. 3 is an exploded perspective view of the fixing bracket 1. As shown in Fig. 3, the fixing bracket 1 includes a clamping member (first member) 10, an arm member (second member) 20, and a fastening member 30 for fastening the clamping member 10 and the arm member 20 together. The fastening member 30 is formed from a screw, and has a shank 30a with a threaded groove formed therein and a head 30b that engages with a tool such as a screwdriver or socket. The fastening member 30 is a member that fastens the clamping member 10 and the arm member 20 together in the inward and outward directions of the stud 100.

[0026] As also shown in Figure 1, the arm member 20 has an outer plate portion 21 that abuts against one side surface 101 of the partition wall 100 from the outside of the partition wall 100, and a box mounting plate portion 22 to which the box B is attached with screws or the like, and is formed by pressing a plate material such as a steel plate.

[0027] The outer plate 21 extends widthwise along one side surface 101 of the stud 100 and also extends vertically. The widthwise dimension of the outer plate 21 is set to be longer than the widthwise dimension of the opening 101a. Therefore, the outer plate 21 extends from the base portion 101c of one hook portion 101b to the base portion 101c of the other hook portion 101b.

[0028] An insertion hole 21a, through which the shaft 30a of the fastening member 30 is inserted, is formed in the middle of the width of the outer plate 21 so as to penetrate the thickness of the outer plate 21. The dimension of the insertion hole 21a in the width direction of the outer plate 21 is longer than the dimension in the up-down direction, and the insertion hole 21a has a shape that is long in the width direction of the outer plate 21. Therefore, when the clamping member 10 and the arm member 20 are temporarily assembled with the fastening member 30, the inner plate 11 can open obliquely relative to the outer plate 21, and the inner plate 11 can be inserted inside the hook portion 101b. This also allows for manufacturing errors in the stud 100 and each component.

[0029] The outer plate portion 21 is formed with first screw holes 21b and second screw holes 21c, through which screws (indicated by reference numeral 40 in FIG. 8) other than the fastening member 30 are inserted, so as to penetrate the thickness direction of the outer plate portion 21. The first screw hole 21b is located on one side of the insertion hole 21a of the outer plate portion 21 in the width direction. The second screw hole 21c is located on the other side of the insertion hole 21a of the outer plate portion 21 in the width direction. Therefore, the first screw hole 21b and the second screw hole 21c are located so as to sandwich the insertion hole 21a. The first screw hole 21b and the second screw hole 21c can be circular, but may also be elongated holes that are long in the width direction of the outer plate portion 21. Furthermore, since the center of the insertion hole 21a and the centers of the first screw hole 21b and the second screw hole 21c are at the same height, the first screw hole 21b, the insertion hole 21a, and the second screw hole 21c are formed side by side in the width direction of the outer plate portion 21.

[0030] The box mounting plate 22 extends from the widthwise end of the outer plate 21 in a direction perpendicular to one side surface 101 of the stud 100 and also extends in the vertical direction. The box mounting plate 22 is provided with a scale 22a (shown in FIG. 3) that indicates the distance from the base end of the box mounting plate 22. The length and shape of the box mounting plate 22 can be set as desired.

[0031] Like the arm member 20, the clamping member 10 is formed by pressing a plate material such as a steel plate. The clamping member 10 is inserted into the inside of the stud 100 through the opening 101a in the stud 100, and has an inner plate portion 11 that abuts against one hook portion 101b from the inside of the stud 100. As shown in Figure 4, the inner plate portion 11 extends in the vertical direction and in the width direction of the stud 100.

[0032] As shown in Figure 3, at one widthwise end of the inner plate portion 11, a first support plate portion 13 is formed above and below the abutting plate portion 12. The first support plate portion 13 protrudes toward the base end of the hook portion 101b and abuts against the inner surface of the hook portion 101b. The first support plate portion 13 is located on the other widthwise side of the stud 100 than the abutting plate portion 12, and is spaced apart from the inner surface on the side surface 104 side of the stud 100. When fastened with the fastening member 30, the tip of the first support plate portion 13 abuts against the inner surface of the base portion 101c of the hook portion 101b.

[0033] A second support plate 14 is formed at the other widthwise end of the inner plate 11 so as to protrude in the same direction as the first support plate 13 and extend in the vertical direction. The second support plate 14 is formed continuously from the upper end to the lower end of the inner plate 11.

[0034] 4 and 5, an abutment plate portion 12 is formed in the vertical middle portion of the edge of the inner plate portion 11. The abutment plate portion 12 extends along the inner surface of the side surface 104 of the stud 100 in a direction parallel to the protruding direction of the hook portion 101b, and is the portion that comes into contact with the inner surface of the side surface 104 of the stud 100. The abutment plate portion 12 comes into contact with the inner surface of the side surface 104 of the stud 100, thereby stabilizing the fixing bracket 1.

[0035] 3 and 4, a screw hole 11a is formed in the inner plate portion 11 so as to penetrate the inner plate portion 11 in the thickness direction. The screw hole 11a is located in the middle of the inner plate portion 11 in the width direction and also in the middle of the inner plate portion 11 in the up-down direction. A thread is formed on the inner peripheral surface of the screw hole 11a, into which the shaft portion 30a of the fastening member 30 is screwed.

[0036] A plurality of protrusions 11b are formed in the widthwise intermediate portion of the inner plate portion 11, protruding toward the base end side of the hook portion 101b. The protrusions 11b are formed simultaneously with the press-forming of the steel plate, and therefore the backside portions of the protrusions 11b on the inner plate portion 11 are recessed to form recessed portions. In this embodiment, two protrusions 11b are formed spaced apart from each other in the vertical direction. The number of protrusions 11b is not limited to two, and may be one, or three or more.

[0037] 5, in plan view, protrusion 11b is formed between contact plate 12 and screw hole 11a. That is, protrusion 11b is positioned away from contact plate 12 on the other widthwise side of stud 100, and is positioned away from screw hole 11a on one widthwise side of stud 100.

[0038] The protrusion amount of the protrusion 11b is set so that it is greatest at the center of the width of the protrusion 11b and becomes smaller as it approaches both ends of the width of the protrusion 11b. By setting the protrusion amount of the protrusion 11b in this manner, the surface of the protrusion 11b as a whole is configured as a curved surface that bulges out from the surface of the inner plate portion 11.

[0039] Therefore, when engaging the protrusion 11b with the tip of the hook portion 101b, the protrusion amount of the protrusion 11b is greatest at the center of the width direction and becomes smaller as it approaches both ends of the width direction, so that the protrusion 11b can be securely engaged on the inside or outside of the hook portion 101b.

[0040] 5, when the hook portion 101b of the stud 100 is wide, the tip of the protruding plate portion 101d abuts against the side of the protrusion 11b that is closer to the screw hole 11a. By setting the position of the protrusion 11b in this way, the fixing bracket 1 can be positioned on the stud 100 that has the wide hook portion 101b.

[0041] On the other hand, as shown in Figure 6, when the hook portion 101b of the stud 100 is narrow, the tip of the protruding plate portion 101d abuts on the side of the protruding portion 11b closer to the first support plate portion 13. By setting the position of the protruding portion 11b in this way, it is possible to position the fixing bracket 1 on a stud 100 having a narrow hook portion 101b.

[0042] 4, the upper protrusion 11b is disposed at the same height as the vertical middle portion of the upper first support plate 13, and is spaced apart on the other widthwise side from the upper first support plate 13. The widthwise separation distance between the upper protrusion 11b and the upper first support plate 13 is set to be longer than the thickness dimension of the protruding plate portion 101d of the hook portion 101b.

[0043] Like the upper protrusion 11b, the lower protrusion 11b is disposed at the same height as the vertical middle portion of the lower first support plate 13, and is spaced apart on the other widthwise side from the lower first support plate 13. The widthwise separation distance between the lower protrusion 11b and the lower first support plate 13 is set to be longer than the thickness dimension of the protruding plate portion 101d of the hook portion 101b.

[0044] A pair of upper and lower guide portions 15 are formed on the inner plate portion 11 to guide the outer plate portion 21 of the arm member 20 to a predetermined position. The upper guide portion 15 protrudes in the same direction as the second support plate portion 14 from a portion of the inner plate portion 11 above the first support plate portion 13. The lower edge of the upper guide portion 15 is inclined so that it is positioned higher as it approaches the tip in the protruding direction. The lower guide portion 15 protrudes in the same direction as the second support plate portion 14 from a portion of the inner plate portion 11 below the first support plate portion 13. The upper edge of the lower guide portion 15 is inclined so that it is positioned lower as it approaches the tip in the protruding direction. Therefore, the distance between the lower edge of the upper guide portion 15 and the upper edge of the lower guide portion 15 increases as it approaches the tip in the protruding direction.

[0045] Furthermore, the distance between the lower edge of the upper guide portion 15 and the upper edge of the lower guide portion 15 is set to be approximately equal to the vertical dimension of the outer plate portion 21 of the arm member 20 at the base end in the protruding direction of the guide portion 15. By forming the pair of upper and lower guide portions 15 as described above, when fastening the outer plate portion 21, the outer plate portion 21 can be easily guided to a predetermined position between the upper guide portion 15 and the lower guide portion 15 by the upper guide portion 15 and the lower guide portion 15.

[0046] 3 and 4, a hook portion 14a is formed on the outer plate portion 21 for hooking onto the second support plate portion 14. The hook portion 14a is configured as a claw-shaped portion that protrudes toward the other widthwise side from a vertically intermediate portion at the end of the second support plate portion 14. As shown in Fig. 5, when the hook portion 14a is inserted into the second screw hole 21c of the outer plate portion 21, the hook portion 14a protrudes along the outer surface of the outer plate portion 21 toward the base end of the box mounting plate portion 22, so that the hook portion 14a is hooked onto the peripheral edge of the second screw hole 21c of the outer plate portion 21 and locked.

[0047] (How to fix the fixing bracket 1 to the stud 100) When fixing the fixing bracket 1 configured as described above to a stud 100, first, the shank 30a of the fastening member 30 is inserted through the insertion hole 21a of the arm member 20 and screwed into the screw hole 11a of the clamping member 10. At this time, as shown in FIG. 7 , the hook portion 14a is hooked onto the periphery of the second screw hole 21c of the outer plate portion 21, and the fastening member 30 is loosely screwed into the screw hole 11a so that the clamping member 10 can move relative to the arm member 20—specifically, so that the inner plate portion 11 can be tilted relative to the outer plate portion 21. This state is called the untightened state. In this way, the clamping member 10 and the arm member 20 can be temporarily assembled using the fastening member 30 in the untightened state, which prevents the fastening member 30 and the clamping member 10 from falling off when the clamping member 10 is attached to the stud 100.

[0048] Then, the inner plate portion 11 of the clamping member 10 is inserted into the stud 100 through the opening 101a in the stud 100. In the case of a wide hook portion 101b, the tip of the protruding plate portion 101d is positioned on the side of the protrusion 11b closer to the screw hole 11a, as shown in FIG. 5 . As the fastening member 30 is tightened, the hook portion 14a hooks onto the peripheral edge of the second screw hole 21c of the outer plate portion 21, so the inner plate portion 11 of the clamping member 10 and the outer plate portion 21 of the arm member 20 move closer to each other, and the hook portion 101b, which is located between the inner plate portion 11 and the outer plate portion 21, is clamped by the inner plate portion 11 and the outer plate portion 21. In this state, the tip of the protruding plate portion 101d abuts against the side of the protruding portion 11b closer to the screw hole 11a, and further, the first support plate portion 13 abuts against the inner surface of the base portion 101c of the hook portion 101b. Also, the abutment plate portion 12 abuts against the inner surface on the side of the side surface 104 of the stud 100. Note that in the case of a narrow hook portion 101b, as shown in FIG. 6, with the hook portion 101b sandwiched between the inner plate portion 11 and the outer plate portion 21, the tip of the protruding plate portion 101d abuts against the side of the protruding portion 11b closer to the first support plate portion 13.

[0049] 8, the arm member 20 can also be fixed to a stud 300 that does not have an opening. In this case, the arm member 20 is fixed to the stud 300 with two screws (tapping screws) 40, without using the clamping member 10 and the fastening member 30. That is, after determining the fixing height of the arm member 20, pilot holes for the screws 40 are drilled in the stud 300. The screws 40 are then inserted into the first screw hole 21b and the second screw hole 21c, respectively, and screwed into the pilot holes in the stud 300. In this way, the second screw hole 21c can be used as a screw insertion hole because it is a hole through which the screw 40 can be inserted, but it can also be used as a hole into which the hook portion 14a can be inserted and hooked, as shown in FIG.

[0050] (Effects of the embodiment) As described above, in this embodiment, when fixing the fixing bracket 1 to the stud 100, the clamping member 10 and the arm member 20 are temporarily assembled, and the inner plate portion 11 of the clamping member 10 is inserted into the stud 100 through the opening 101a in the stud 100. Then, as shown in Fig. 5, the protrusion 11b of the clamping member 10 is formed in the middle portion of the inner plate portion 11 in the width direction, so that when the width of the hook portion 101b is wide, the protrusion 11b engages with the tip of the hook portion 101b from the inside of the hook portion 101b, thereby positioning the fixing bracket 1; and when the width of the hook portion 101b is narrow, the protrusion 11b engages with the tip of the hook portion 101b from the outside of the hook portion 101b, thereby positioning the fixing bracket 1.

[0051] Thus, according to this embodiment, whether the hook portion 101b is wide or narrow, the same fixing bracket 1 can be fixed in a positioned state relative to the stud 100, making it possible to fix one type of fixing bracket 1 to multiple types of studs 100.

[0052] The above-described embodiments are merely examples in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Industrial Applicability]

[0053] As described above, the fixing bracket according to the present disclosure can be used, for example, when fixing a box for fixing a switch, an outlet, etc. to a stud. [Explanation of symbols]
