Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a steady rest and a detachment prevention member for a sliding screen door installed on the outdoor side of a sliding shoji screen.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Application No. 54-137245,
A steady rest member having a groove formed in the upper part to receive the upper rail for the screen door provided in the sash frame, and a stopper member for regulating the depth of the groove are formed of synthetic resin molded products, and both of the members are made of synthetic resin. There is known a shoji slip-off prevention and steady rest device in which a sliding shoji door is rotatably tightened with a screw, and a steady rest member is fixed to the upper end of a vertical stile of a sliding shoji door.

[The problem that the idea aims to solve]

With the conventional device described above, it is almost impossible to change the depth regulation dimension of the concave groove of the steady rest member using the stopper member, so the door roller fixed to the lower stile of the screen door installed using the Kendon method may come off the rail while running. However, once the screen door is fitted, the dimensions cannot be adjusted, so there is a problem that the screen door cannot be easily removed.

In addition, in the above-mentioned conventional anti-seismic and steady-rest devices, both the anti-stable member and the anti-seizure member are made of synthetic resin molded products, which increases the cost of the mold and makes it expensive. When used for screen doors, there was also the problem that it was difficult to obtain sufficient rigidity due to the small size.

The present invention solves the above-mentioned problems, makes it possible to accurately adjust the dimensions in the vertical direction, reliably prevents the screen door from coming off, has sufficient rigidity, and is inexpensive. It is an object of the present invention to provide a screen door steady rest and a detachment prevention member that are easy to install at a screen door installation site.

[Means to solve the problem]

The screen door steady rest and removal prevention member according to the present invention consists of a steady rest member 1 made of synthetic resin and a removal prevention member 2 made of a metal plate. A groove 6 is formed to receive the upper rail 23 for the sliding screen door 14 provided in the screen door 14, and a round hole 9 is formed in the lower part 5 of the screen door 14 supported by the vertical stile 15. A guide protrusion 10 for the retaining member 2 is provided in a protruding manner, and a cutout groove 8 is formed in the upper part of the side on which the guide protrusion 10 is formed, the lower end of which is open via a step 30 and extends upward. The retaining member 2 has a long hole 1 extending in the vertical direction.
1, and an operating protrusion 12 bent outward at the lower end.
and a guide protrusion 13 for regulating the depth of the groove 6 at the upper end, a guide protrusion 10 in the elongated hole 11, and a guide protrusion 13 in the groove 6, respectively. The anti-slip member 2 is fitted onto the steady rest member 1 so as to be slidable in the vertical direction.

[Effect]

The screen door steady rest and removal prevention member according to the present invention are shipped from the factory with the removal prevention member in the lowered position and tightened with screws to the vertical stile together with the steady rest member. Up,
After fitting the top and bottom of the screen door stile to the bottom rail, loosen the screws, raise the retaining member by the required amount using the operating protrusion, and tighten the screws again.
Since the screen door can be used without fear of coming off the upper and lower rails, the installation operation at the installation site is easy, and the removal prevention member can be positioned vertically relative to the screw and steady rest member within the size of the long hole. Can be adjusted.

Therefore, the depth of the groove is appropriately regulated by the guide protrusion provided at the upper end of the retaining member, and an appropriate distance between the door roller attached to the lower stile of the screen door and the upper end of the retaining member is maintained. This makes it possible to reduce vertical rattling of the screen door and reliably prevent the screen door from coming off.

Furthermore, since the retaining member is made of a metal plate, it is less expensive than conventional products in which the retaining member is formed of a synthetic resin molded product, and the rigidity can be increased, and the screen door can be moved easily.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In Figures 1 and 2, 1 is a vertically elongated steady rest member made of an integrally molded synthetic resin such as polyethylene that has some degree of elasticity, and 2 is a stamped and bent product of a metal plate such as a stainless steel plate. This is a vertically elongated retaining member.

As shown in FIGS. 3 to 5, the steady rest member 1 includes an upper part 3 and a plate-shaped lower part 5 connected to each other via a step 4, and the upper part 3 is formed with a groove 6 that opens on the upper surface. A narrow groove 7 is formed on both side surfaces of the groove 6 in an extending direction of the inner surface of the lower part 5 over the entire length of the upper part 3 in the vertical direction.

Reference numeral 8 denotes a notched groove, and as shown in FIG. The groove 7 is formed parallel to the narrow groove 7 and extends upward.

In the upper part 3, thick parts 3a and 3b are formed on one side and a part of the other side of the groove 6. Further, the lower portion 5 is formed with a round hole 9 and a guide protrusion 10 for stopping the sway, which is located above the round hole 9 and protrudes outward. This guide projection 10 has a rectangular plate-shaped head 10b integrally formed at the tip of a guide portion 10a having a circular cross section.

On the other hand, the retaining member 2 is shown in FIGS. 6 and 7.
As shown in the figure, a long hole 11 is formed along the vertical direction, an operating protrusion 12 is formed at the lower end, and a guide protrusion 13, which also serves as a steady rest, is bent outward at a right angle and protrudes at the upper end. It is set up.

In the relationship between the guide protrusion 10 and the elongated hole 11, the retaining member 2 is
The guide portion 10a of the guide protrusion 10 is formed with an outer diameter that fits without any gaps, and the head portion 10b is formed with a long width and length in the vertical direction.
The width of the steady rest member 1 is formed to be somewhat shorter than the width of the steady rest member 1.

Hereinafter, the order of assembling the stopper member 2 and the steady rest member 1 to the screen door frame will be explained.

First, the retaining member 2 is attached to the outer surface of the lower part 5 of the steady rest member 1, with the longitudinal directions perpendicular to each other as shown by the chain lines in FIG. 10a, and the upper part of the steady rest member 1 is elastically deformed so as to expand toward the front near the opening of the notch groove 8, and in this state, the anti-sway member 2 and the steady rest member 1 are
By rotating these by about 90° so that their longitudinal directions coincide, the guide protrusion 13 of the retaining member 2 can be fitted into the groove 6.

Next, by fitting both side edges of the upper part of the retaining member 2 into the notch groove 8 without any gaps, the guide protrusion 13 of the retaining member 2 comes into contact with the bottom of the groove 6, as shown in FIG. With the upper edge of the elongated hole 11 in contact with the guide portion 10a of the guide protrusion 10 at the lower limit position,
The anti-slip member 2 is superimposed on the outer surface of the lower part 5 of the steady rest member 1. In this state, the groove 6 and the guide protrusion 1
3 work together to act as a guide for the screen door rail.

In addition, as shown in FIGS. 2 and 9, an uncut portion 1 is formed on the outer wall 16 of the hollow portion at the upper end of the vertical stile 15 of the screen door 14.
6a to form a notch 16b, and as shown in FIG.
18 to form the screen door 14. Then, as shown in FIG. 8, the steady rest member 1 with the detachment prevention member 2 assembled is inserted into the vertical stile 15 from above, and the narrow groove 7 is inserted into the uncut portion 16a of the outer wall 16 as shown in FIG. The screw 19 is passed through the elongated hole 11 and the round hole 9, and the screw 19 is fitted into the hole 20 (see FIG. 10) in the lower part of the uncut portion 16a of the outer wall 16, and the steady rest is attached to the outer wall 16. The lower part 5 of the member 1 and the retaining member 2 are tightened and fixed together.

As described above, the steady rest and the stopper member are provided at the upper end corner 15a of the left stile 15 of the screen door 14, but by using the steady rest member and the stopper member with opposite left and right hands, the right stile 15 top corner 1
5b is also provided with a steady rest and a stopper member.

Screen door 14 shipped from the factory as described above
is carried to the installation site, and the upper frame 2 of the sash frame 21 that has been erected in the building in advance is installed as shown in Fig. 1.
By fitting the concave groove 6 of the steady rest member 1 into the upper rail 23 for the screen door provided in 2, and fitting the door roller attached to the lower end of the stile of the screen door 14 onto the lower rail for the screen door (not shown) to support it. , attach the screen door 14 to the frame 21
Attach to.

At the time of this installation, as shown in FIG. 8, since the retaining member 2 is at its lower limit,
3 and the upper rail 23, the screen door 14 can be easily attached to the sash frame 21.

Next, loosen the screw 19 slightly, push the operating protrusion 12 upwards with a screwdriver, etc., and raise the retaining member 2 by the required amount to narrow the gap between the upper rail 23 and the guide protrusion 13, and create a concave groove. By appropriately regulating the depth of 6 and tightening screw 19 again,
To reduce rattling in the vertical direction of a screen door 14 and prevent the screen door 14 from coming off from the upper and lower rails.
Furthermore, when the screen door 14 is opened and closed, both sides of the concave groove 6 of the steady rest member 1 come into sliding contact with both sides of the screen door upper rail 23, so the screen door 14 does not rattle.
You can get smooth and stable running.

In this embodiment, the opening end 7a of the narrow groove 7 is inclined so that the opening side widens as shown in FIG. It can be easily inserted into the

In addition, as shown in FIG. 3, both sides of the groove 6 of the steady rest member 1 are inclined so that the upper part of the groove 6 is slightly wider, so that the steady rest member 1 can be placed at the upper end of the vertical stile 15. When fitted, it has good adhesion with the vertical frame 15, and when the groove 6 is engaged with the upper rail 23 for the screen door, the groove 6 has the same width in the vertical direction, but due to elastic restoring force. Since the groove 6 tends to expand upward, engagement can be facilitated.

Furthermore, as shown in FIG. 6 and FIG. The screen door 14 is in sliding contact with the screen door 14 to facilitate the installation work to the screen door 14 and to reduce sliding resistance.

If only one of the guide protrusion 13 and the guide protrusion 10 is provided as necessary, the two-point support with the screw 19 will allow the retaining member 2 to be moved around the axis of the screw 19 relative to the steady rest member 1. Since the guide protrusion 13 can be moved vertically with almost no vibration, one of the guide protrusions 13 can be omitted.
Since the screen door upper rail 23 may come into contact with the screen door upper rail 23, the contact area is widened to make the screen door 14 run smoothly.
This helps to prevent the upper end of the retaining member 2 from colliding with the other member and damaging it.
