Description

  The present invention relates to a louver window protector and a method for reinforcing the louver window.

2. Description of the Related Art Conventionally, as a window device for a bathroom or kitchen, for example, a louver window that can be easily opened and closed from the indoor side and can be easily ventilated is known.
The louver windows are arranged at equal intervals in the vertical direction on the inner surfaces of the pair of left and right vertical frames, and the window frame that is framed in a rectangular shape from the upper and lower frames and the pair of left and right vertical frames, and swings up and down on the inner side surfaces. A plurality of louver supports that are freely pivoted, louver blades that are supported with both left and right ends fitted to the louver supports, and an indoor side for simultaneously swinging the louver supports vertically (Refer to patent document 1).

For this reason, in the louver window, when the drive mechanism is operated in the closing direction, each louver support swings in the vertical direction, and the upper and lower ends of the louver blades are in a closed posture, and the drive mechanism is opened. When the operation is performed, each louver support swings in the horizontal direction, and the upper and lower end portions of the louver blades are separated from each other.
In addition, in order to improve the crime prevention property of such louver windows, a louver window is provided that prevents a thief from entering the room even if the louver window is destroyed by installing a lattice window on the indoor side of the louver window.

In the louver window, if the front end wall portion of the louver support exposed to the outside of the room is broken, the louver blade can be extracted from the outside of the room, and this point is regarded as a security weakness of the louver window. Yes.
As described above, although the front end wall portion of the louver support that supports the louver blade is a weak point for crime prevention, the front end wall portion of the louver support only covers the front end surface of the louver blade by so-called caulking. There is a louver window with a hanging structure. In the case of a louver window having such a louver support, the louver blade can be easily pulled out to the outdoor side by bending the front end wall of the louver support with a general tool such as a screwdriver. It was particularly vulnerable above.

  On the other hand, as described in Patent Document 2, if a lattice window is installed on the indoor side of the louver window, an intruder can be prevented from entering by removing the louver blade from the outdoor side. However, there is a problem that the installation is large and expensive, and the indoor space is narrowed by the installation of the lattice window.

  Therefore, an object of the present invention is to prevent the louver blade from being extracted from the outdoor side by a simple method, and to improve the security of the louver window at a low cost.

  The present invention is a protector for a louver window that solves the above-mentioned problems, and this protector can cover the front end wall portion of a louver support pivotably mounted on the inner side surface of a vertical frame constituting the louver window. A front plate, a top plate extending rearward from the upper end of the front end plate and having substantially the same length in the front-rear direction as the louver support, and a rear plate extending from the lower end of the front end plate and the louver support And a fastening part for fastening the rear ends of the top plate and the bottom plate to each other on the indoor side of the louver window.

In order to mount the protector on the louver window, the protector formed in a frame shape that can circulate along the outer peripheral surface of the louver support is inserted into the louver support from the outdoor side toward the indoor side. The fastening portion at the rear end portion of the protector may be fastened on the indoor side of the louver window.
At this time, since the front end wall portion of the louver support is covered with the front end plate of the protector, even if there is a thief who breaks the front end wall portion and pulls out the louver blade, the front end wall portion is broken. Therefore, it takes time and effort. For this reason, the probability that the thief will give up pulling out the louver blade is increased, and the crime prevention property of the louver window is improved.

  Further, according to the present invention, since the louver blade can be prevented from being pulled out from the outdoor side only by attaching the louver protector to each louver support, the material cost is also higher than when the lattice window is installed on the indoor side. Construction work is also inexpensive, and the security of the louver window can be improved at a low cost.

In the protector according to the present invention, the fastening portion includes an upper fastening plate extending downward from a rear end of the upper surface plate, and an upper portion extending upward from a rear end of the lower surface plate and overlapping the upper fastening plate. It can comprise from the lower fastening plate which can be screwed as a state.
In this case, the fastening operation of the fastening portion is completed simply by screwing the fastening screws from the indoor side to the upper and lower fastening plates in a superposed state, and therefore, the indoor work for attaching the protector is extremely difficult. It becomes simple.

Further, the protector according to the present invention is configured such that the upper surface plate can be changed to either an open leg position in which the upper and lower fastening plates are separated from each other or a closed leg position in which the upper and lower fastening plates are overlapped with each other. It is preferable that the lower plate and the lower plate are bendable and deformable with respect to the front end plate.
In this case, since the protector inserted into the louver support in the state of the open leg posture can be easily put into the closed leg posture, the mounting operation of the protector becomes easier.

  Furthermore, in the protector according to the present invention, the upper plate or the lower plate is provided with a latch piece that is hooked on the outer end surface of the louver support to prevent the louver window protector from being moved toward the center of the louver window. Alternatively, if provided on both of them, the protector after being mounted is prevented from being laterally displaced and detached from the louver support, and the crime prevention function of the protector is more reliably maintained.

  As described above, according to the present invention, it is possible to prevent the louver blade from being pulled out from the outdoor side only by attaching the louver protector to each louver support, so that the security of the louver window can be improved at a low cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a louver window to which the protector of the present invention is applied.
The louver window 1 includes a metal window frame 2 made of an aluminum extrusion-molded product or the like framed in a rectangular frame shape. The window frame 2 includes a pair of upper and lower upper frames 3 and 4 and these And a pair of left and right vertical frames 5 that connect the left and right ends of each other.

The louver window 1 according to the present embodiment includes the window frame 2, a plurality of louver supports 6 arranged at equal intervals in the vertical direction on the inner surfaces of both vertical frames 5 constituting the window frame 2, and both left and right ends. Louver blades 7 that are supported in a state in which the portions are fitted to the left and right louver supports 6, and a drive mechanism 8 that is disposed on the indoor side for simultaneously swinging the louver supports 6 up and down. I have.
Each of the plurality of louver supports 6 is formed by bending a metal plate such as a steel plate, and includes a pair of upper and lower clamping plates 10 and 11, an outdoor front end wall portion 12, and an indoor rear end. And a wall portion 13.

The front end wall portion 12 of the louver support 6 is so-called caulked by bending the front end portion of the upper clamping plate 10 downward. For this reason, in the louver window 1 of the present embodiment, the front end surface of the left and right end portions of the louver blade 7 inserted between the sandwiching plates 10 and 11 is hooked by the front end wall portion 12 by caulking. The louver blade 7 is fixed to the louver support 6.
In addition, although the louver blade | wing 7 of this embodiment is glass, it is reinforced so that a thief cannot break easily by sticking the metal reinforcement plate 14 on the lower surface.

It is pivotally attached to the relative rotation.
The drive mechanism 8 is composed of a box body having an operation lever 17 that can be freely rotated, and this box body is attached to the indoor side surface of the vertical frame 5. Inside the box body, there is provided a motion conversion mechanism such as a gear mechanism for converting the rotational motion of the operation lever 17 into the vertical linear motion of the interlocking bar 16.

  For this reason, when the operation lever 17 of the drive mechanism 8 is rotated, the interlocking bar 16 linearly moves up and down, and thereby each support arm 15 swings up and down. Accordingly, when the operation lever 17 of the drive mechanism 8 is operated in the closing direction, each louver support 6 swings in the vertical direction via the interlocking bar 16 so that the upper and lower ends of the louver blades 7 overlap each other. It becomes. On the other hand, when the operation lever 17 of the drive mechanism 6 is operated in the opening direction, each louver support 6 swings in a horizontal direction via the interlocking bar 16 and the upper and lower ends of the louver blades 7 are separated from each other. It becomes.

  As shown in FIGS. 1 to 3, the louver window protector 30 of the present embodiment is formed in a frame shape that can circulate along the outer peripheral surface of the louver support 6, and the front end of the louver support 6. A front end plate 19 capable of covering the wall portion 12, a top plate 20 extending rearward from the upper end of the front end plate 19 and having substantially the same length in the front-rear direction as the louver support 6, and rearward from the lower end of the front end plate 19 And a fastening portion 22 for fastening the rear ends of the top plate 20 and the bottom plate 21 to each other on the indoor side of the louver window 1. And.

The protector 30 of the present embodiment is formed by bending a metal plate such as a steel material, for example, and integrally includes the front end plate 19, the upper surface plate 20, the lower surface plate 21, and the fastening portion 22. Among these, the front end plate 19 has a vertical dimension substantially corresponding to the front end wall portion 12 and a width dimension substantially corresponding to or slightly larger than the front end wall portion 12.
Further, the upper surface plate 20 substantially corresponds to the upper holding plate 10 or has a slightly larger width, and the lower surface plate 21 corresponds to the lower holding plate 11 or has a slightly larger width. Have dimensions.

In addition, the upper surface plate 20 and the lower surface plate 21 of the protector 30 are formed with step portions at appropriate positions so as to conform to the outer peripheral shape viewed from the side surface of the louver support 6 (see FIG. 2). The material of the protector 30 is sufficient if it is strong enough that it cannot be easily broken by a thief. For example, FRP, other hard plastics, or the like can be used.
The fastening portion 22 includes an upper fastening plate 23 that extends downward from the rear end of the upper surface plate 20 and a screw that extends upward from the rear end of the lower surface plate 21 and is superposed on the upper fastening plate 23. And a possible lower fastening plate 24.

Of the upper and lower fastening plates 23, 24, the upper fastening plate 23 is located on the indoor side in the overlapped state, and has a screw insertion hole at the center. On the other hand, the lower fastening plate 24 is located on the outdoor side in a superposed state, and has a screw threaded portion formed by burring or the like at the center.
For this reason, when the protector 30 of the present embodiment is placed in the closed leg posture (the phantom line state in FIG. 2), the upper and lower fastening plates 23 and 24 are superposed on each other, and in this state, the fastening screw 25 (see FIG. 1). ) Are screwed together so that the fastening plates 23 and 24 can be connected to each other.

As shown in FIG. 2, the protector 30 of the present embodiment has an open leg posture (solid line state in FIG. 2) in which the upper and lower fastening plates 23, 24 are separated from each other, and the upper and lower fastening plates 23, 24 are superposed on each other. The upper surface plate 20 and the lower surface plate 21 can be bent and deformed with respect to the front end plate 19 so that the posture can be changed to either the closed leg posture (the phantom line state in FIG. 2).
As shown in FIGS. 2 and 3, a latching piece 26 extending downward is formed on one end side in the width direction of the upper surface plate 20, and the latching piece 26 is formed on the outer end surface of the louver support 6 ( It has a function of preventing the protector 30 after being attached to the center side of the louver window 1 from being hooked on the edge in the width direction of the upper clamping plate 10.

Next, a method for reinforcing the louver window 1 using the protector 30 having the above-described configuration and the function and effect of the protector 30 will be described.
First, in order to attach the protector 30 of the present embodiment to the louver window 1, as shown by the arrow in FIG. 1, the protector 30 in the open leg position is moved from the outdoor side to the indoor side with respect to the louver support tool 6.
