Description

[Detailed Description of the Invention] The present invention relates to a door roller attachment device that is attached to the lower rail of a screen door in order to smoothly slide the door.

The width of the lower frame of the screen door, especially the adjuster of the lower stile, is generally narrow, so the door roller that is attached to the narrow interior of the screen via a support bracket is even thinner, allowing the screen door to maintain a stable state and slide smoothly. Moreover, since the adjuster is narrow, it requires a lot of effort to attach the door roller via the support bracket.

Therefore, in this invention, by supporting the screen door roller with a single plate piece, the width of the door roller is made as thick as possible to achieve stable sliding, and the support of the door roller is supported by a cantilever. By doing it in a combined manner,
The object of the present invention is to propose a door roller mounting device that can be easily assembled and mounted and eliminates the above-mentioned conventional drawbacks.

An embodiment of the present invention shown in the drawings will be described below.

Fig. 1 is a front view of the lower end of the screen door with a part cut away. 1 shows the lower stile of the screen door, and an adjuster 2 with a U-shaped cross section is attached to the lower stile 1 of the lower stile of the screen door. It is mounted so that it can freely move up and down with the space 3 facing downward.

Reference numeral 4 denotes a bracket consisting of a vertical piece 5 and a horizontal piece 6 formed from an elastic plate.A U-shaped locking hole 7 is formed in the horizontal direction at approximately the center of the vertical piece 5, and the horizontal piece 6 has a mounting hole 7. A hole 8 is drilled for the purpose.

The locking hole 7 has an expanded guide portion 7a at its side opening.
By providing this, it is possible to easily insert and engage the pin 13, which will be described later.

Further, the locking hole 7 may be formed so that the U-shaped portion faces upward or downward instead of being formed so as to face laterally.

As shown in Figures 1 and 2, the bracket 4 is attached to the adjuster 2.
It is attached to the space 3 by fixing the screw 9 into the hole 8.

This bracket 4 is attached in close contact with the inner surface of the space 3 of the adjuster 2.

Of course, when the adjuster 2 is not used as a lower stile, the bracket 4 will be directly attached to the lower stile as a lower stile.

10 shown in Figures 2 and 3 is a wheel with a deep recess 1 on the circumferential surface.
1 is formed, and a through hole 12 is bored laterally in the center.

It is desirable that the width of the wheel 10 has a thickness that approximately matches the inner width of the space 3 of the adjuster 2 to which the bracket 4 is attached.

By increasing the width of the wheel, the recess 11 can be formed deep without affecting the strength.

13 shown in FIG. 5 is a pin that becomes the axle of the wheel 10,
It is inserted into the through hole 12 of the wheel 10, and the groove part 14 formed at the - side end is inserted and engaged with the locking hole 7 of the bracket 4 from the lateral direction, and the support parts 15 and 16 at both end parts are respectively inserted. The wheel 10 is inserted into circular shaft holes 17, 17 formed on the side surface of the adjuster 2, and is rotatably attached to the space 3 of the adjuster 2.

Due to this engagement of the groove portion 14 with the locking hole 7, the pin 13 is firmly supported by the bracket 4 even though it is cantilevered.

Next, the assembly and installation of the door roller mounting device of the present invention will be explained.

First, the pin 13 is inserted into the through hole 12 of the wheel 10, and the groove 14 of the pin 13 is engaged with the locking hole 7 of the bracket 4, and the bracket 4 is adjusted as shown in FIGS. Attach the adjuster 2 to the space 3 in such a way that the vertical piece 5 and the horizontal piece 6 are in close contact with the inner wall surface, and hold the adjuster 2 in a slightly expanded state by hand and insert the support parts 1 at both ends of the pin 13.
The wheel 10 is rotatably attached to the adjuster 2 by inserting the wheels 5.16 into the shaft holes 17, 17 of the adjuster 2.

As described above, in the present invention, the wheels are supported in a cantilevered manner via pins using a bracket consisting of a vertical piece and a horizontal piece using thin plate pieces, so that the internal width space of the lower crosspiece can be fully occupied. By using this method, the width of the wheels can be made thicker, and the screen door using the wide door roller can run and slide smoothly in a stable state.

Furthermore, when attaching the pin to the bracket, the groove of the pin is engaged with the engagement hole of the bracket, so that it can be firmly attached even though it is supported in a cantilevered manner.

Further, since the bracket is engaged with the pin only on one side as described above, the engagement operation becomes easy.

Furthermore, the locking of the pin in the locking hole has the effect of making the locking operation extremely easy, since the groove portions can be brought into alignment while the pin is engaged with the guide portion of the locking hole. .
