Description

[Technical Field]

[0001] The present invention relates to a mounting bracket that enables security cameras, sensors, lighting fixtures, etc. to be attached to the sub-beams of a wire mesh ceiling or cable rack, for example. [Background technology]

[0002] A security camera mounting structure for mounting a security camera is described in Patent Document 1. This mounting structure uses a substantially L-shaped bracket 8 to which a bolt 12 is welded and attached to the side surface 13 of the elevator car.

[0003] This type of mounting structure allows security cameras to be installed in existing elevator cabs.

[0004] Meanwhile, a mounting structure for a mesh panel is described in Patent Document 2. This mounting structure is for mounting a mesh panel to a wall surface or the like, and is a structure in which the mesh panel is fixed to the wall surface using mounting bracket 4 having a front substrate 41 and a rear substrate 43.

[0005] This connecting structure makes it possible to selectively connect and fix mesh panels attached to a wall surface or the like via gaps. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-103580 [Patent Document 2] Patent No. 5731222 Summary of the Invention [Problem to be solved by the invention]

[0007] The security camera mounting structure described in Patent Document 1 can mount a security camera in an elevator car by using a substantially L-shaped bracket 8. However, it is difficult to mount this bracket 8 in other facilities.

[0008] That is, when installing security cameras or the like during structural construction, they are attached to the wire mesh ceiling, the sub-girders of the cable rack, etc. However, the bracket 8 in Patent Document 1 is designed specifically for the wall surface of the car room, etc., and is therefore not versatile, and cannot be installed in different locations.

[0009] Furthermore, the mounting structure described in Patent Document 2 is a structure for fixing a mesh panel to a wall surface, etc. Therefore, no consideration is given at all to mounting a security camera, a sensor, a lighting fixture, etc. on this mesh panel.

[0010] On the other hand, wire mesh ceilings used in structural construction, etc., come in a wide variety of wire diameters and wire pits. Therefore, when installing security cameras, sensors, lighting fixtures, etc. on wire mesh ceilings, custom manufacturing or on-site processing is required to fit the needs of the site.

[0011] Furthermore, depending on the site, security cameras and the like may be mounted on not only the wire mesh ceiling but also the sub-girders of the cable rack.

[0012] The present invention was created to solve the above-mentioned problems, and aims to provide mounting hardware that can be used to attach devices such as security cameras, sensors, and lighting fixtures to attachment targets such as wire mesh ceilings, cable racks, sub-girders and channel materials of ladder-type cable racks, etc. during structural construction work. [Means for solving the problem]

[0013] In order to achieve the above-mentioned object, the first means of the present invention is a mounting bracket for mounting equipment such as a surveillance camera, a sensor, or a light to an object to be mounted P, which comprises a mounting base 1 that is connected to the equipment, a clamping bracket 3 that clamps and holds the object to be mounted P together with the mounting base 1, and a fastening member for fastening the mounting base 1 and the clamping bracket 3.

[0014] The mounting base 1 of the second means has a plate-shaped mounting piece 2 that faces the clamping metal fitting 3 and clamps the mounting object P, and the mounting piece 2 has one round hole 2A and one notch 2B for screwing the clamping metal fitting 3 to the mounting piece 2.

[0015] The mounting object P of the third means is a mesh-like structure of intersecting linear materials, and the clamping fitting 3 is a plate member 3A, which clamps the mesh-like structure together with the mounting base 1 by covering the intersection points where the linear materials intersect or by covering multiple linear materials.

[0016] The fourth means is that the mesh structure is a wire mesh ceiling, the mounting base 1 is provided with a plate-shaped mounting piece 2 that faces the plate member and sandwiches the wire mesh ceiling, and at least one of the plate member 3A and the mounting piece 2 is formed with a fitting groove into which the wire P1 that constitutes the wire mesh ceiling fits.

[0017] In the fifth means, the mounting object P is a structure having an approximately rectangular cross section, the clamping fitting 3 is a U-shaped bolt 3B, and the U-shaped bolt 3B is clamped together with the mounting base 1 while straddling the structure having an approximately rectangular cross section.

[0018] The sixth means is such that the mounting object P is a sub-girder P2 of a cable rack, the U-shaped bolt 3B is a U-shaped bolt, the mounting base 1 has a mounting piece 2 facing the U-shaped bolt and clamping the mounting object, and the U-shaped bolt is connected to the mounting piece 2.

[0019] The seventh means is a mounting fixture that includes a plurality of types of clamping fittings 3 adapted to different mounting objects P, and that allows the clamping fittings 3 to be replaced depending on the mounting object P.

[0020] The eighth means is a mounting bracket for mounting a device such as a surveillance camera, a sensor, or a light to a mounting object P, the mounting object P being a wire P1 of a wire mesh ceiling or a sub-girder P2 of a cable rack, The device comprises a mounting base 1 on the underside of which the device is attached, a plate-shaped mounting piece 2 fixed to the upper surface of the mounting base 1 and abutting against the underside of the wire P1 or the sub-girder P2, and a clamping fitting 3 engaged with the upper surface of the wire P1 or the sub-girder P2, The clamping fitting 3 includes a plate member 3A that is engaged with the wire P1 and screwed in place with a connecting bolt 4, and a U-bolt 3B that is engaged with the sub-girder P2. Depending on the object P to be attached, the plate member 3A or the U-bolt 3B is selected and screwed to the attachment piece 2.

[0021] The mounting piece 2 of the ninth means has a fitting groove 2C into which the wire P1 is fitted, and the plate member 3A has a holding portion 3Aa that holds from above another wire P1 that crosses over the wire P1 fitted into the fitting groove 2C.

[0022] The tenth means is configured to form a round hole 2A and a notch 2B in the mounting piece 2, and to screw the plate member 3A or the U-bolt 3B to the mounting piece 2, and to temporarily fasten the connecting bolt 4 or the U-bolt 3B in the round hole 2A, and to insert the connecting bolt 4 or the U-bolt 3B from the side into the notch 2B.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention is a mounting bracket for attaching equipment such as a surveillance camera, a sensor, or a light to a mounting object P. The mounting object P is, for example, a wire P1 of a wire mesh ceiling (see FIG. 1), or, for example, a sub-girder P2 of a cable rack (see FIG. 2). In this case, the wire mesh ceiling may be another mesh structure, and the sub-girder P2 of the cable rack may also be changed to another structure having a substantially rectangular cross section.

[0027] The main components of the present invention include a mounting base 1, a mounting piece 2, and a clamping metal fitting 3, with the clamping metal fitting 3 used varying depending on the mounting object P (see Figs. 1 and 2). The mounting object P is clamped between the mounting piece 2 and the clamping metal fitting 3 and fastened with screws.

[0028] The mounting base 1 is a member on the underside of which a security camera, a sensor, a light, or other device is attached, and mounting pieces 2 are provided on the top surface of the mounting base 1 (see FIGS. 1 and 2).

[0029] The mounting piece 2 is a plate-like member having a support leg 2D erected on the upper surface of the mounting base 1 (see FIGS. 1 and 2). The support leg 2D is fixed to the mounting base 1 by screwing a connecting bolt 6 into a screw hole 2Da drilled in the bent lower end of the support leg 2D. The method of fixing the support leg 2D to the mounting base 1 is not limited to screwing as described above, and it may also be fixed by caulking, for example.

[0030] This mounting piece 2 is used by abutting it against the underside of the object P to be mounted. The plate surface of the mounting piece 2 is provided with a round hole 2A and a notch 2B (see FIG. 3(A)) in order to screw in the clamping fitting 3 (described later) with a connecting bolt 4 or a U-bolt 3B. With this configuration, when screwing the clamping fitting 3 to the mounting piece 2, after temporarily fastening one bolt in the round hole 2A, the other bolt can be inserted and fixed from the side into the notch 2B, improving workability and reducing the risk of the clamping fitting 3 falling off.

[0031] On the other hand, the clamping metal fitting 3 is a member that engages with the upper surface of the mounting object P (see Figures 1 and 2). The mounting base 1 can be attached to the mounting object P by clamping the mounting object P between the mounting piece 2 and the clamping metal fitting 3, and by attaching equipment such as a surveillance camera, sensor, or lighting to the mounting base 1, the equipment can be attached to the mounting object P.

[0032] Example 1 A case where the attachment object P is a mesh structure will be described using a wire mesh ceiling as an example.

[0033] In this case, a plate member 3A is used as the clamping metal fitting 3. This plate member 3A is in the form of a plate that is engaged with the upper surface of the wire P1, which is a linear material that constitutes the mesh structure (while sandwiching the wire P1) and overlaps with the mounting piece 2 (see FIG. 4(A)).

[0034] A pair of screw holes 3Ab for inserting connecting bolts 4 are formed in the plate surface of the illustrated plate member 3A (see FIG. 4(A)). This plate member 3A is provided with a holding portion 3Aa that holds the upper wire P1 of the crossed wires P1 from above (see FIG. 4(B)). This holding portion 3Aa is formed so as to curve along one longitudinal side edge of the plate member 3A. Here, the holding portion 3Aa functions as a fitting groove into which the wire P1 is fitted.

[0035] The mounting piece 2 of this embodiment has a fitting groove 2C into which the wire P1 is fitted (see FIG. 3(A)). This fitting groove 2C is recessed so as to intersect with the mounting piece 2 at the center in the longitudinal direction of the mounting piece 2 (see FIG. 3(B)).

[0036] Then, of the crossed wires P1, the lower wire P1 is fitted into the fitting groove 2C of the mounting piece 2 (see FIG. 3(b)). Furthermore, the upper wire P1 is covered with the holding portion 3Aa, and the crossed portion of the wire P1 is sandwiched between the plate member 3A and the mounting piece 2, and then the plate member 3A and the mounting piece 2 are screwed in place with the connecting bolt 4 (see FIG. 1).

[0037] As a result, even in the case of a wire mesh ceiling, where the wire diameters and wire pits of the wire P1 are various, common use is possible by clamping the intersection of the wire P1 between the plate member 3A and the mounting piece 2.

[0038] Furthermore, the operation of screwing the plate member 3A to the mounting piece 2 is performed with one of the connecting bolts 4 temporarily fastened in the round hole 2A (see FIG. 5). That is, after one of the connecting bolts 4 is temporarily fastened, the other connecting bolt 4 is inserted into the cutout 2B from the side, and each connecting bolt 4 is fixed with a wing nut 5. In this way, the operation of screwing the plate member 3A is simplified.

[0039] In this embodiment, plate member 3A is used as clamping fitting 3, and the parts where linear materials such as wires that make up the mesh structure intersect are clamped between plate member 3A and mounting piece 2, thereby preventing the mounting fitting from rotating or swinging. Furthermore, the mounting fitting can also be prevented from rotating or swinging by clamping plate member 3A and mounting piece 2 across multiple linear materials rather than at the parts where the linear materials intersect.

[0040] In this example, the holding portion 3Aa of the plate member 3A is formed so as to be curved along one longitudinal edge of the plate member 3A, but the position and number of holding portions 3Aa can be changed as appropriate. For example, they may be formed on both sides along the longitudinal edge, or along a direction perpendicular to the longitudinal direction. Figure 7(A) shows an embodiment in which holding portions 3Aa are formed on both sides along a direction perpendicular to the longitudinal direction. Figure 7(B) shows an embodiment in which the connecting bolt 4 is combined into one bolt, as shown in Figure 7(A), and a pair of engaging claws 3Ac that engage with the mounting piece 2 are formed on the opposite side perpendicular to the opposite side on which the pair of holding portions 3Aa are formed. This prevents the plate member 3A from rotating relative to the mounting piece 2.

[0041] In this embodiment, the fitting groove 2 is recessed so as to intersect with the mounting piece 2 at the center in the longitudinal direction of the mounting piece 2, but the forming positions and number of the fitting grooves 2 can be changed as appropriate.

[0042] Example 2 A case where the mounting object P is a structure having a substantially rectangular cross section will be described using a sub-girder P2 of a cable rack as an example.

[0043] In this case, a U-bolt 3B is used as the clamping metal fitting 3 (see Figure 2). This U-bolt 3B is locked in a state in which it straddles the sub-girder P2. Furthermore, both ends of the U-bolt 3B are screwed to the mounting pieces 2.

[0044] In this case, this is done with one side of U-bolt 3B temporarily fastened in round hole 2A of mounting piece 2 (see Figure 6). That is, after temporarily fastening one side of U-bolt 3B in round hole 2A, the other side of U-bolt 3B is inserted from the side into notch 2B of mounting piece 2 and fixed with wing nut 5 (see Figure 6). In this way, the screwing work of U-bolt 3B is also simplified.

[0045] Example 3 A mounting bracket kit that allows selection of clamping brackets 3 depending on the mounting object P will be described.

[0046] The kit of this embodiment includes at least the plate member 3A of Example 1 and the U-bolt 3B of Example 2 as clamping fittings 3, and further includes the mounting piece 2 and mounting base 1 of Example 1. The plate member 3A may include multiple types of plate members with different positions and numbers of holding portions 3Aa.

[0047] With the kit of this embodiment, it is possible to select a clamping fitting 3 that corresponds to the mounting object P, such as a surveillance camera, a sensor, or a light, depending on the site where the device is to be mounted. For example, if the mounting object P is a wire P1 on a wire mesh ceiling, a plate member 3A is selected as the clamping fitting 3 (see FIG. 1). If the mounting object P is a sub-girder P2 of a cable rack, a U-bolt 3B is selected as the clamping fitting 3 (see FIG. 2).

[0048] Furthermore, the shapes of each component of the present invention are not limited to the illustrated examples, and the configurations of the mounting base 1, mounting piece 2, clamping fitting 3, etc. can be freely modified in design within the scope that does not change the gist of the present invention.

[0049] It is also possible to use the plate member 3A when the object to be attached is a structure having a substantially rectangular cross section, such as the sub-girder P2 of a cable rack. In this case, a long connecting bolt 4 may be used. [Explanation of symbols]
