Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a screen frame structure of a screen door that is assembled to a doorway of a building or the like.

[Problems to be Solved by Conventional Techniques and Inventions] Generally, this type of screen door may be installed side by side with an existing sliding door or the like for ventilation. At this time, the screen door frame is attached to the existing door frame. However, such existing door frame has variations in the building dimensions, and the screen door frame of the standard size cannot often be used as it is. Therefore, conventionally, for example, as shown in Japanese Utility Model Laid-Open No. 59-168497, a screen frame is
It is composed of an inner member and an outer member that is fitted and inserted on the outer side of the inner member, and the outer member is projected and retracted inward and outward by turning the adjusting screw,
There is one that allows adjustment of the outer dimensions of the screen frame. However, in order to cover the gap between the corners of the upper frame and the vertical frame that occurs when the outer member is projected, this is a corner plate that can be retracted between the inner member and the outer member, as shown in FIG. 17 is inserted, the corner plate 17 is projected to a position where it covers the gap in the corner portion, and then fixed by the screw 18. For this reason, screws and screw holes need to be machined, these are exposed to the outside, which is not desirable in appearance, and the corner members must be adjusted at the screen door frame installation site. It has the drawback of being time-consuming.

[Means for Solving the Problems] The present invention was conceived in view of the above circumstances to provide a screen frame structure capable of eliminating these drawbacks, and constitutes a screen frame. In a screen door frame having a double frame structure in which each of the vertical and horizontal frames is composed of a fixed frame member and a movable frame member that is slidable inward and outward relative to the fixed frame member, one of the vertical and horizontal frames Although it moves integrally with the movable frame member in the moving direction in the accommodating portion formed at the end of the movable frame member, it becomes slidable in the moving direction of the other vertical and horizontal movable frame member orthogonal to this. While the corner plate is fitted inside, the corner plate is fitted in the engaging groove formed in the other vertical and horizontal movable frame member and integrally moves in the moving direction of the other vertical and horizontal movable frame member. An engaging piece that is slidable in the moving direction of one movable frame member that is orthogonal to It is characterized by being present.

Further, according to the present invention, when the movable frame member is slid inward / outward, the present invention eliminates the need for adjusting the corner plate.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, 1 is a screen door frame to which a folding door type screen door 2 is assembled, and the screen door frame 1 is composed of an upper frame 3, a lower frame 4, left and right vertical frames 5, 6, and the like.

Now, taking the upper frame 3 (corresponding to the lateral frame of the present invention) as an example, the upper frame 3 has a fixed upper frame (corresponding to a fixed frame member of the present invention) 7 having a substantially sectional shape and a substantially sectional shape. And a movable upper frame (corresponding to the movable frame member of the present invention) 8 having a double frame structure. The movable upper frame 8 is fitted onto the fixed upper frame 7 in a vertically slidable state. is doing. That is, on the inside of the frame at the left and right ends of the upper side 8a forming the movable upper frame 8,
Omitted in side view The shaped adjustment liner 9 is screwed to the upper piece 9a 10
It is attached integrally by being done. A screw hole 9c is formed in the bottom surface 9b of the adjusting liner 9, and an adjusting screw 11 is screwed into the screw hole 9c from below with the screw head 11a facing downward.

On the other hand, on the inner side of the frame of the lower side 7b forming the fixed upper frame 7, two front and rear bispokes 12 extending in the left-right direction are formed to face each other. Screws 13 for forming a frame and the frames 5a and 6a are screwed into the frame. And this pair of biscuits 12
Have openings on the opposite sides facing each other in a groove shape. The screw head 11a of the adjusting screw 11 is fitted and locked in the opening groove 12a so that the screw head 11a is allowed to rotate around the shaft center and is prevented from moving back and forth in the shaft center direction.

Further, the lower side 7b of the fixed upper frame 7 is provided with a tool hole 7c for rotating the adjusting screw 11. And adjusting screw
When the screw head 11a is rotated with an appropriate tool, the movable upper frame 8 moves the adjustment liner 9 up and down without moving back and forth in the axial direction with respect to the fixed upper frame 7. It is configured to be able to slide up and down.

To assemble the movable upper frame 8 to the fixed upper frame 7, use the screw head.
The movable upper frame 8 may be slid from one of the left and right sides of the fixed upper frame 7 by fitting the front and rear edges of the fixed upper frame 7 into the opening groove 12a. 5a, 6a
The front end of the frame screw 13 for forming the frame just comes into contact with the screw head 11a of the adjusting screw 11, whereby the movable upper frame 8 moves in the left-right direction with respect to the fixed upper frame 7. It is configured to be positioned.

In addition, the left and right vertical frames 5, 6 are fixed vertical frames 5a, like the upper frame 3,
It has a double frame structure consisting of 6a and movable vertical frames 5b and 6b.
The movable vertical frames 5b and 6b are adapted to slide in the left-right direction by the rotation of the adjusting screw 11. And these movable upper frames 8
By sliding the movable vertical frames 5b and 6b inward and outward, the outer dimensions in the height direction and the left-right direction of the screen frame 1 can be adjusted according to the building dimension.

Furthermore, one side surface portion of the movable upper frame 8 projects outward, and a storage portion 14 is formed between it and one side surface portion of the fixed upper frame 7, and the storage portion 14 has a corner plate. 15 is slidable in the left-right direction and is fitted so as to move integrally in the up-down direction. On the other hand, the outer edge of the corner plate 15 is formed with an engaging piece 15a protruding from the edge of the movable upper frame 8, and the engaging piece 15a is formed on the movable vertical frames 5b and 6b. The groove 16 is slidable in the vertical direction, but is engaged in the horizontal direction so as to move integrally. When the movable upper frame 8 is slid in the vertical direction, the corner plate 15 moves up and down integrally with the vertical movement of the movable upper frame 8. At this time, the engagement piece 15a is engaged with the engaging groove 1a.
As it slides inside 6, the amount of protrusion of the corner plate 15 from the movable upper frame 8 is maintained as it is, and the gap between the corner portions generated between the movable vertical frames 5b and 6b is closed. On the other hand, when the movable vertical frames 5b and 6b are slid in the left-right direction, the corner plate 15 has the engaging pieces 15a whose movable vertical frames 5b and 6b.
It is engaged with the engaging groove 16 of the upper frame 3 and moves integrally with the movable vertical frames 5b and 6b in the left-right direction.
The gaps formed at the corners between the vertical frames 5 and 6 can be automatically closed by the corner plates 15.

In the embodiment of the present invention constructed as described above, as described above, the upper frame 3 and the vertical frames 5, 6 are fixed frame members 7, 5a, 6a.
And the movable frame members 8, 5b, 6b have a double frame structure. By rotating the adjusting screw 11 and sliding the movable frame members 8, 5b, 6b inward and outward, the height of the screen frame 1 is increased. The outer dimensions in the horizontal and horizontal directions can be adjusted, but at this time the upper frame 3
The gap between the corners of the vertical frames 5 and 6 can be automatically covered by the corner plate 15.

That is, the storage portion 14 between the fixed upper frame 7 and the movable upper frame 8 of the upper frame 3.
A corner plate 15 is slidably inserted in the left and right directions, and the corner plate 15 further includes an engaging groove 16 of the movable vertical frames 5b and 6b.
An engagement piece 15a that engages with is formed. Therefore, when the movable vertical frames 5b and 6b are slide-adjusted in the left-right direction, the corner plate 15 follows this and slides in the left-right direction, while the movable upper frame 8 is slide-adjusted in the vertical direction. Also in this case, the corner plate 15 moves integrally with the movable upper frame 8 in a state of covering the corner portion where the amount of protrusion from the movable upper frame 8 is maintained.

In the present invention, the corner plate 15 is used to close the corner portion.
Also, the movable vertical frames 5b and 6b are automatically moved in accordance with the inner and outer movements of the movable vertical frames 5b and 6b to cover the gaps formed at the corners between the upper frame 3 and the vertical frames 5 and 6, and thus, are conventionally required. In addition to the fact that screws and screw holes for fixing the corner plates are not required, the troublesome work of moving and fixing the corner plates 15 to the position that covers the gap is required at the installation site of the screen frame 1. Since it is not necessary to do it, it can greatly contribute to the improvement of workability.

Needless to say, the present invention is not limited to the above-described embodiment, and can be implemented by reversing the vertical and horizontal relationships.

[Advantages] In summary, since the present invention is configured as described above, the horizontal frame and the vertical frame have a double frame structure of a fixed frame member and a movable frame member, and the movable frame member is inside and outside. By sliding it in the direction, the outer dimensions of the screen frame in the height direction and the left-right direction can be adjusted, but at this time, the corner plate moves following the movable frame material of the horizontal frame and the vertical frame, Will automatically cover the gap between the vertical frame and the corner. Therefore, it is not permissible to eliminate the need for screws and screw holes for fixing the corner plate, which was conventionally required, and it is possible to avoid exposing these members to the outside and making them unsightly.
Further, it is not necessary to carry out the troublesome work of moving and fixing the corner plate to the position covering the gap at the installation site of the screen frame, which can greatly contribute to the improvement of workability.
