Description

[Detailed Description of the Invention] The present invention relates to a fixed screen door mounting device that is fixedly attached to a louver window or a casement window.

Conventionally, screen doors that are fixedly attached to louvered windows or casement windows generally have a configuration in which the four circumferences of the frame are screwed to the sash frame, which requires the work of screwing together numerous screws one by one. It required a lot of effort. On the other hand, in order to eliminate the above-mentioned installation effort, some systems employ a structure in which the screen door is attached to the sash frame by a fitting method, but the sash frame does not meet the specified dimensions due to the shape error of the window opening. Therefore, this fitting method has the disadvantage that it is very difficult to adjust dimensional errors.

The present invention was made in view of the above points, and by equipping the frame of the screen door with height and width adjustment functions, it is possible to fully accommodate the specified dimensional error of the sash frame to which it is attached, and The present invention proposes a fixed screen door mounting device that has a simple structure, allows the above-mentioned adjustments, and can be extremely easily attached to a sash frame.

An embodiment of the present invention shown in the drawings will be described in detail below. FIG. 1 is a longitudinal sectional view of this embodiment in use, FIG. 2 is a cross-sectional view of FIG. 1, FIG. 3 is a partial front view of the screen door, and FIG. 4 is an exploded view of the screen door upper stile.

In the above figures, the fixed screen door mounting device of this embodiment is a fixed screen door 1 that is mounted on the four circumferential side wall pieces 11 of a sash frame 10, and includes a locking member 5 provided on the screen door upper stile 2A, and a screen door lower stile 2B. are provided with locking pieces 6 and 7,
In addition, the side portions 8 of both vertical frames 2C of the screen door 1 are brought into contact with the indoor side wall pieces 11C of the sash vertical frame 10C, and the locking pieces 6, 7 of the upper and lower frames 2A, 2B of the screen door 1 are brought into contact with each other.
are secured to the indoor side wall pieces 11a, 11b of the upper and lower sash frames 10A, 10B.

The sash frame 10 in this embodiment is an upper frame 10A.
The lower frame 10B and both vertical frames 10C are used as a frame, and the louver blade body 12 is attached to the linking body 13 within this frame.
It is attached so that it can be opened and closed by a handle 14 through the handle. However, in addition to the louver blades, a casement window body or the like may be installed within the frame.

The screen door 1 that is attached and fixed to the sash frame 10 has four circumferences of the screen portion 1a, an upper stile 2A, a lower stile 2B, and both vertical stile 2.
It is constructed by assembling a frame body 2 consisting of C.

As shown in FIGS. 3 and 4, the upper stile 2A of the screen door 1 described above has an elastic member 4 inside a recess 3 with an open top surface.
The locking member 5 is fitted and attached via the locking member 5. The locking member 5 in the embodiment has a cross section of approximately L.
It has a letter-shaped shape, is fitted into the recess 3 against the elasticity of an elastic member 4, and has an upper portion projecting upwardly from the recess 3 so as to be vertically movable due to the elasticity. Since a protrusion 3a projecting laterally is provided in the recess 3, the locking member 5 is prevented from detaching from the recess 3 by being engaged by the same protrusion 5a.

As shown in FIG. 3 as an example, the elastic member 4 is attached by bending a spring plate piece into a curved shape, and fitting supporting parts 4a at the ends to both ends of the locking member 5, respectively. By integrally attaching the elastic member 4 to the locking member 5 in this manner, attachment to the recess 3 of the upper stile 2A becomes easy. The elastic member 4 attached in this manner allows the height of the screen door 1 to be freely adjusted by moving the locking member 5 up and down a fixed height from the recess 3. The elastic member 4 may be constructed by embedding a wavy spring plate piece in the recess 3, or may be constructed from a soft synthetic resin block.

The locking member 5 described above is integrally provided with a hook-shaped locking piece 6 that projects from the side of the upper end toward the side wall piece 11a of the sash upper frame 10A. This hook-shaped locking piece 6 is removably locked from the indoor side to the lower end of a side wall piece 11a provided in a hanging manner on the indoor side surface of the upper frame 10A. Since this locking piece 6 is constructed integrally with the locking member 5, it moves up and down by the elasticity of the elastic member 4 and locks onto the lower end portion of the side wall piece 11a.

Lower frame 10B and both vertical frames 1 in the sash frame 10
0C is provided with protruding side wall pieces 11b and 11c of the same shape within the same peripheral surface as the side wall piece 11a of the upper frame 2A.
Therefore, a sash frame opening 21 is formed on the indoor side surface of the sash frame 10, and is surrounded by side wall pieces 11a, 11b, and 11c. The screen door 1 is attached to this sash frame opening 21 from the indoor side.

Next, on the outside of the lower end room of the screen door lower stile 2B, a sash lower frame 10B is placed in correspondence with the locking piece 6 of the upper stile 2A.
A hook-shaped locking piece 7 protruding toward the side wall piece 11b of the
is installed protrudingly. This locking piece 7 has a downward hook shape and locks onto the upper end portion of the side wall piece 11b of the lower stile 10B. Since this locking piece 7 is integrally molded with the lower stile 10B, it is easy to manufacture.

As mentioned above, the upper and lower frames 2A and 2B of screen door 1
The sash frame 10 is provided with locking pieces 6 and 7, respectively.
The vertical frame 2C is fixed to the side wall pieces 11a and 11b of the vertical frame 10C, while the side surfaces of both vertical frames 2C are brought into contact with the respective side wall pieces 11c of the vertical frame 10C. The side surfaces of both vertical frames 2C are each provided with a protruding piece 8 whose outdoor side surface protrudes laterally, and this abuts against each side wall piece 11c from the indoor side, and is fixed at a constant level with respect to the side wall piece 11c. The contact surface has a width of . This contact surface is designed to absorb dimensional errors between the sash frame 10 and the screen door frame 2. In addition, the above-mentioned projecting pieces 8, 8 are such that the locking pieces 6, 7 of the upper and lower frames 2A, 2B are connected to the side wall pieces 11a, 11.
b is configured to abut against the side wall piece 11c in the state of being locked. Note that the side surface of the vertical stile 2C may have a structure in which the main body having a hollow cross section directly contacts the side wall piece 11c without forming the projecting piece 8. In addition, the above-described frame body 2, locking member 5, etc.
Mainly constructed from extruded aluminum.

Next, a method of attaching the screen door to the sash frame in the above embodiment will be explained. First, with the locking member 5 fitted to the upper stile 2A via the elastic member 4, the locking piece 7 of the screen door lower stile 2B is attached to the sash lower frame 10.
Then, the side surfaces 8 of both vertical frames 2C are brought into contact with the side wall pieces 11c of the sash vertical frame 10C, and at the same time, the locking pieces 6 of the upper stile 2A are secured to the elastic members. The screen door 1 is attached to the sash frame 10 by pushing it down against the elasticity of the sash upper frame 10A and locking it to the end of the side wall piece 11a of the sash upper frame 10A. At this time, the locking piece 6 of the upper stile 2A moves up and down to adjust the dimension in the height direction within the vertical movement width, and the side surface 8 of the vertical stile 2C comes into contact with the side wall piece 11c of the vertical frame 10C. Dimensions in the left and right direction will be adjusted within the width of the abutting surfaces. In the above embodiment, an example was shown in which a screen door is attached to a louver window, but it can also be attached to a double sliding shoji window.In this case, side wall pieces are provided around the outside side of the sash frame, A screen door with a similar configuration will be attached to the side wall piece.

The fixed screen door installation device of the present invention is as described above.
The vertical stile has a projecting piece protruding laterally from the side surface in contact with the indoor side wall piece of the sash frame, the lower stile has a locking piece that locks, and the upper stile has a locking piece that can move up and down. Since the locking piece is configured to lock, even if a specified dimensional error occurs in the sash frame to which a specific screen door is attached, the dimensional error in the height direction will be covered by the vertically movable upper locking piece. The width can be adjusted using the projecting pieces of the vertical stile, making it possible to freely deal with dimensional errors in the sash frame. Moreover, despite having the above-mentioned dimensional error adjustment function, the device of the present invention locks the lower locking piece to the side wall piece of the lower frame, and pushes up the upper locking piece against the side wall piece of the upper frame against the elastic force. Since this can be done with a one-touch locking operation, it has the advantage of being extremely easy to install.
