[Prior art]
Conventionally, as a technology to improve the security of the face grid attached to the outside of the window of a building such as a house, when fixing the bracket to the wall of the house, a screw or a normal screwdriver that cannot be turned without a special tool In some cases, a screw having a special shape such as a screw that can only be turned in the tightening direction is used. That is, by using this specially shaped screw, the risk of removing the face grid from the outside has been reduced, and crime prevention has been improved.
[0003]
However, specially shaped screws and special tools usually have the disadvantage of being costly. In addition, because there are few people who are accustomed to using specially shaped screws and special tools, the surface grid is attached using screws and tools that are generally used as much as possible. Work efficiency is improved. Furthermore, since the screws for fixing the bracket to the wall surface are exposed to the outside when the surface grid is attached, there is a concern that the aesthetics may be impaired.
[0004]
Therefore, in the prior art, a bracket that is fixed to the window sash when the face grid is attached in order to prevent the face grid from being removed from the outside without using specially shaped screws or the like. There is a mounting structure of a surface grid using a bracket shaped so that the base is covered with the surface grid (see, for example, Patent Document 1). According to the technique described in Patent Document 1, it is possible to provide a surface grid mounting structure with excellent crime prevention and design.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the first embodiment and the second embodiment of the bracket of the present invention will be described with reference to the drawings.
[0027]
FIG. 1 shows an example of a usage state of the bracket of the present invention. As shown in the figure, a method of increasing crime prevention by attaching a face grid 20 to the outside of a residential window 22 has been widely used. Here, when the conventional bracket is used, there is a problem that a fixing member such as a screw for fixing the bracket to the wall surface 21 is exposed to the outside. The present invention uses the bracket 1 having a shape to which the bracket cap 10 can be easily attached, thereby preventing the member for fixing the bracket 1 to the wall surface from being exposed to the outside, and improving the aesthetics of the surface lattice. It is characterized by improving crime prevention.
[0028]
FIG. 2 is a diagram illustrating a configuration of the bracket 1 according to the first embodiment. Here, FIG. 2A shows the state of the bracket 1 before attaching the bracket cap 10 as the cover member of the present invention, and FIG. 2B shows the state of the bracket 1 after attaching the bracket cap 10. Is shown. FIG. 3 is a diagram showing an example of a surface grid mounting structure using the bracket 1.
[0029]
First, the configuration of the bracket 1 according to the present embodiment will be described with reference to FIGS. 2 and 3. The bracket 1 in the present embodiment is made of stainless steel, and includes a fixed piece 6 fixed to the wall surface 21 of the residence, a lattice attachment piece 4 to which the surface lattice 20 is attached, and the fixed piece 6 and the lattice attachment piece 4. It is comprised with the connection piece 5 to connect. As shown in the figure, the fixed piece 6, the connecting piece 5, and the lattice mounting piece 4 are bent at a substantially right angle therebetween. However, the bending angle is not necessarily 90 degrees, and an appropriate bending angle can be set in consideration of the place where the bracket 1 is used, the strength required for the bracket 1, and the like.
[0030]
In the present embodiment, the fixing piece 6 constitutes the fixing portion of the present invention, the connecting piece 5 constitutes the connecting portion of the present invention, and the lattice attaching piece 4 constitutes the lattice attaching portion of the present invention. Further, the arrangement of the fixed piece 6, the connecting piece 5, and the lattice mounting piece 4 is not limited to the above-described configuration, and variations in the shape of the bracket 1 can be increased by changing the bending angle or the like. is there. For example, it is possible to make the bracket 1 L-shaped by arranging the grid mounting piece 4 and the connecting piece 5 on the same plane. When this L-shaped bracket is used together with the bracket 1, it becomes possible to fix one end of the surface grid to a wall surface and the other end to a wall surface orthogonal to the wall surface. The degree of freedom is improved.
[0031]
The lattice mounting piece 4 is a rectangular plate-like member with rounded corners, and is disposed on one end side of the bracket. Alternatively, the lattice attachment piece 4 has holes 9a into which screws 8 for fastening the surface lattice 20 and the lattice attachment piece 4 are inserted. As shown in FIG. 3, when the surface lattice 20 is attached to the lattice attachment piece 4, the lattice attachment piece 4 is fixed to the surface lattice 20. At this time, a part of the frame of the surface lattice 20 and the lattice attachment piece 4 are sandwiched and fixed by the screws 8 and the back plate 7.
[0032]
A plate-like fixing piece 6 is disposed on the other end side of the bracket 1. The fixing piece 6 has a hole 9b into which a screw for fixing the bracket 1 to the wall surface 21 is inserted. The fixing piece 6 is formed with a locking recess 3 having a trapezoidal cross section at the front. In this embodiment, the locking recess 3 constitutes the first locking portion of the present invention. As shown in FIG. 3, a fixing member such as a screw is inserted into the hole 9b of the fixing piece 6 and the fixing member is screwed into the wall surface, thereby fixing the fixing piece 6 to the wall surface.
[0033]
The connecting piece 5 is a member for connecting the lattice mounting piece 4 and the fixed piece 6 described above. As shown in the figure, the connecting piece 5 has a rectangular plate shape. Further, the connecting piece 5 has a long hole-like locking hole 2 formed at a predetermined height from the lower end thereof. In the present embodiment, the locking hole 2 constitutes the second locking portion of the present invention.
[0034]
FIG. 4 shows a configuration of the bracket cap 10 attached to the bracket 1. As shown in the figure, the bracket cap 10 in the present embodiment has a bucket shape in which a hard resin material is used and a wall plate in one direction is missing. That is, the bracket cap 10 includes a rectangular plate-like cover portion 15 with rounded corners and a wall plate 16 extending from three sides of the cover portion 15 so as to be orthogonal to the surface of the cover portion 15.
[0035]
The bracket cap 10 has a hook portion 12 for locking at an end portion of the cover portion 15 where the wall plate 16 is not formed. A locking projection 13 is formed at the end of the wall plate 16 extending from the side opposite to the side where the locking hook portion 12 is formed. In the present embodiment, the locking hook portion 12 constitutes the second cover side locking portion of the present invention, and the locking protrusion 13 constitutes the first cover side locking portion of the present invention. Here, since the locking hook portion 12 and the locking projection 13 are formed in parallel to each other, the locking portion on the bracket 1 side formed so as to be opened in a predetermined direction as will be described later. Can be easily engaged.
[0036]
When the bracket cap 10 is attached to the bracket 1, the bracket cap 10 is attached in the direction indicated by the arrow in FIG. On the other hand, the locking hole 2 and the locking recess 3 formed on the bracket 1 side are both in the direction opposite to the mounting direction of the bracket cap 10 (in the direction opposite to the arrow in the figure) and are formed on the wall surface 21. Open in parallel direction. Here, the term “open” means that there is no obstacle such as a wall plate in a predetermined direction (in this case, the direction opposite to the arrow in the figure), and the locking hole 2 and the locking recess 3 from the predetermined direction. This means that you can go in and out freely. As described above, the locking hole 2 and the locking recess 3 are open in a predetermined direction parallel to the wall surface 21 even when the fixed piece 6 is fixed to the wall surface 21. This is because the bracket cap 10 is engaged with the hole 2 and the recess 3 for locking.
[0037]
When the bracket cap 10 is attached to the bracket 1 while moving in the direction of the arrow in the drawing, the locking hook portion 12 is accommodated in the locking hole 2 to form an engagement state, and the locking projection 13 And an engagement recess 3 are also formed. As a result, the bracket cap 10 is fixed in a state of being engaged with the bracket 1, so that the fixing piece 6 of the bracket 1 is covered with the bracket cap 10 as shown in FIG. It can prevent that the fixing member which is fixing is exposed to the outside.
[0038]
FIG. 5 shows variations in the shape of the bracket used in the present embodiment. As shown in the figure, the present invention can also be applied to the case where the connecting piece 5 is provided with an expansion / contraction mechanism so that the connecting piece 5 can be extended and retracted. In addition, as a telescopic mechanism shown in the drawing, a conventionally used configuration can be applied, and the description thereof is omitted here.
[0039]
In addition, if the same pattern and color are given to the bracket 1 and the bracket cap 10 or the same texture is given, the aesthetics of the bracket 1 is improved. Further, in order to give an impression that it is difficult to remove the bracket 1 from the wall surface 21 only by preventing the fixing member that fixes the bracket 1 to the wall surface 21 from being exposed to the outside, the surface is obtained by removing the fixing member. It is possible to reduce the number of cases where the grid 20 is removed. Furthermore, it is possible to improve the corrosion resistance by protecting the fixing member and the like with the bracket cap 10.
[0040]
FIG. 6 shows a configuration of a bracket 1 ′ according to the second embodiment of the present invention. FIG. 6 (a) shows a state before the bracket cap 10 ′ is attached to the bracket 1 ′, and FIG. 6 (b) shows a state where the bracket cap 10 ′ is attached to the bracket 1 ′.
[0041]
As with the bracket 1 in the first embodiment, the bracket 1 ′ is made of a stainless steel material, and includes a lattice mounting piece 4, a connecting piece 5, and a fixed piece 6. However, unlike the bracket 1 in the first embodiment, the bracket 1 ′ is arranged so that the connecting piece 5 is inclined with respect to the fixed piece 6 at a predetermined angle.
[0042]
As in the first embodiment, the lattice attachment piece 4 is attached with the surface lattice 20 via a fastening member. The connecting piece 5 has a trapezoidal plate shape, and is formed such that the interval (width) between both side ends becomes narrower as it goes from the fixed piece 6 side to the lattice mounting piece 4 side. The fixing piece 6 is fixed to a wall surface (not shown) via a fixing member. A locking recess 3 is formed at the end of the fixed piece 6 on the surface side that comes into contact with the wall surface when fixed. The locking recess 3 is formed to open in a predetermined direction parallel to the wall surface. Further, since the locking recess 3 does not appear on the side of the fixed piece 6 opposite to the surface that contacts the wall surface, it does not stand out even when the bracket cap 10 ′ is not attached.
[0043]
FIG. 7 shows a configuration of the bracket cap 10 ′ in the second embodiment. As shown in the figure, the bracket cap 10 ′ includes a cover portion 15 that covers the fixed piece 6, and a wall plate 16 that is disposed at both ends of the cover portion 15 so as to be orthogonal to the cover portion 15.
[0044]
A locking projection 13 is formed at the end of the cover portion 15. Further, a pair of hook-shaped engagement pieces 14 extend from the end portions of the pair of wall plates 16 formed so as to face each other at both end portions of the cover portion 15.
[0045]
When the bracket cap 10 ′ is attached to the bracket 1 ′, the connecting piece 5 is connected to the both ends of the connecting piece 5 on the grid attaching piece 4 side by using the tapered shape of the connecting piece 5. The bracket cap 10 ′ is slid on the fixed piece 6 side of the piece 5. At this time, when the bracket cap 10 'is slid until the locking projection 13 engages with the locking recess 3, the mounting of the bracket cap 10' is completed.
[0046]
However, the connecting piece 5 is not necessarily formed in the above-described tapered shape. For example, when attaching a relatively large surface lattice 20 to the wall surface 21, an intermediate bracket may be used. Usually, the intermediate bracket has a connecting piece 5 having a constant interval between both ends, that is, a rectangular plate shape. May be used.
[0047]
In such a case, when the pair of engaging pieces 14 in the bracket cap 10 ′ are pressed against the connecting piece 5, the distance between the pair of engaging pieces 14 is exerted by the pressing force from both end portions of the connecting piece 5. Has an elastic force so that the distance between the pair of engagement pieces 14 returns to the original state when the engagement state between both end portions of the connection piece 5 and the pair of engagement pieces 14 is formed. By doing so, the bracket cap 10 'can be pressed against the bracket 1' from the front and attached. In order to obtain the above-described action, the pair of engaging pieces 14 need to have a resilient force at least in the surface direction of the connecting piece 5.
[0048]
As shown in the above-described embodiment, the bracket 1 of the present invention has the same appearance as a normal bracket even when the bracket cap 10 is not attached, and after the bracket 1 is fixed to the wall surface 21, Since it is possible to attach the bracket cap 10 in various ways, it is possible to use various methods when attaching the surface grid 20.
[0049]
Finally, regarding the stability of the engagement state between the bracket 1 and the bracket cap 10, since the connecting piece 5 is bent at a predetermined angle with respect to the fixed piece 6, the locking recess 3 and the locking hole 2 are The bracket cap 10 can be engaged with the bracket 1 in a more stable state as compared with the case where they are arranged on the same plane.
[0050]
