Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for adjusting the erection of metal fittings.

Generally, the dimensions of the sill and lintel are not constant.
For this reason, the installation condition of the fittings must be adjusted each time.

Conventional installation adjustments are made by adjusting the mounting height of the door roller, but the adjustment range is small;
Therefore, it is not possible to adequately deal with dimensional differences. Furthermore, in the conventional installation adjustment method, a hole is made in the prospective surface of the vertical stile for the screwdriver to pass through, resulting in an unsightly appearance.

The purpose of this invention is to provide a fitting that has a large adjustment range and has a good appearance without having to make any holes in the vertical stile. A vertical adjustment screw is provided, and the adjustment body can be moved up and down over a large range depending on the amount of rotation of this adjustment screw.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

The installation adjustment device 1 of the present invention has an upwardly directed recess 5 formed in the lower protruding portion of the adjustment body 4 that holds the adjustment crosspiece 2 and the door roller 3, and a screw insertion hole 6 drilled inside the recess 5. , insert the adjustment screw 7 into this screw insertion hole 6.
At the same time, a groove 10 intersecting the recess 5 from the outer surface is provided in the adjustment body 4, and a receiving part 9 having a driver insertion hole 8 inside the groove 10, for example, a receiving plate 9 separate from the main body 15. Insert the adjustment screw 7 to prevent it from coming off, and then tighten the adjustment screw 7.
For example, it is configured by being screwed into a screw hole 14 as a screw receiver bored in the lower surface of a connecting tool 13 that connects the vertical stile 11 and the lower stile 12.

The adjustment body 4 is made of plastic or the like, has an insertion hole 16 in the upper surface of a main body 15 that is approximately L-shaped when viewed from the side, and forms a block-shaped protrusion that fits inside the vertical stile 11. Further, a connecting portion 17 is provided on the other side surface perpendicular to this. The insertion piece 16 is slidably inserted between the facing inner wall of the vertical stile 11 and the auxiliary plate 18. Further, the connecting portion 17 is fitted into the adjustment bar 2 and is attached to the adjustment bar 2 with a mounting screw 19. Mounting screw 1
Reference numeral 9 indicates one mounting portion 2 of the door roller housing 20 at the same time.
1 is fixed. The other end portion of the door roller housing 20 is not fixed to the adjustment bar 2, and remains in a state in which the adjustment screw 22 is screwed therein. When the door roller 3 inside the door roller housing 20 receives a load, the tip of the adjusting screw 22 comes into contact with the inner wall surface of the adjusting bar 2. Therefore, by adjusting the amount of entry of the adjusting screw 22, the mounting height of the door wheel 3 can be adjusted within the screwing range.

Further, as shown in FIGS. 4 and 5, the recess 5 is formed on the lower surface of the main body 15 at a position closer to one facing surface, and the groove 10 is formed slightly above the recess 5 on one side. It fits into the internal recess 5 from the facing surface. A screw insertion hole 6 is bored in the upper bottom part of this recess 5, and the adjusting screw 7 inserted upward from below is inserted into the screw hole 14 bored in the lower surface of the connector 13. ing. After the adjustment screw 7 is inserted, the receiving plate 9 is tightly inserted into the groove 10. This receiving plate 9 is, for example, a metal plate, and the adjusting screw 7
It has a driver insertion hole 8 concentric with the axis of. The inner diameter of this driver insertion hole 8 is smaller than the outer diameter of the head 7a of the adjusting screw 7, but is large enough to allow the tip of the driver 23 to pass through.

Furthermore, as shown in FIGS. 1 and 2, the adjusting body 4 has a groove 24 extending vertically on one edge of the prospective surface.
and a pair of closing pieces 25 at the open end of the groove 24.
It is equipped with The pair of closing pieces 25 are molded with a thickness that can be deformed integrally with the adjustment body 4, and are located at the lower end of the vertical stile 11 when adjusting the adjustment body 4 up and down, and are equal to or equal to the projected surface of the vertical stile 11. In addition to closing the gap that is formed in that part when it is slightly protruding,
It also acts as a buffer.

As clearly shown in FIG. 1, the connector 13 is press-fitted between the auxiliary plate 18 of the vertical stile 11 and a pair of locking pieces 26 at the opening, and is secured to the auxiliary plate by the upper mounting screw 27. It is fixed at 18. An insertion portion 28 protruding from the inner surface fits into the opening at the end of the lower stile 11. This fit is ensured by mounting screws 30 screwed into the upper and lower pin holes 29.

The above-mentioned installation adjustment device 1 is also provided in a symmetrical manner in the other vertical stile portion.

Now, as for the installation adjustment, as already mentioned, the door roller 3
By rotating the adjusting screw 22, adjustment can be made within the range of the maximum screwing amount. In addition, when the door roller 3 is worn out, the door roller 3
can also be lowered. When the door roller 3 is lowered by the adjustment screw 22, one mounting portion 21 of the door roller housing 20 is bent into an F-shape to allow the door roller 3 to descend.

However, further installation adjustments are made by rotating the adjusting screw 7. When lowering the door roller 3 and the adjusting bar 2, the adjusting screw 7 is rotated counterclockwise. This operation is performed from the driver insertion hole 8 using the driver 23. In this way, the adjusting screw 7 retreats from the screw hole 14 of the connector 13 and pushes down the receiving plate 9 with its head 7a. As a result, the adjustment body 4 is displaced downward while holding the adjustment bar 2 and the door roller 3. Of course, if the adjustment screw 7 is rotated clockwise, the adjustment body 4 will move upward. The above adjustment amount is approximately equal to the length of the threaded portion of the adjustment screw 7. When the adjustment body 4 moves up or down, the pair of closing pieces 25 deform the vertical frame 1.
It is pushed by the inner wall surface of frame 11 and enters the inside of groove 24, but the other part is in the position of the prospective surface of vertical stile 11,
In addition to closing gaps in the sash frame and mating fittings (not shown), it also acts as a buffer when opening and closing.

Note that the shapes of the adjusting body 4, the connecting tool 13, etc. are not limited to those in the example, and the shapes of the vertical stile 11, the lower stile 1, etc.
2. It should change depending on the shape of the adjustment bar 2, etc. Also, the door wheel housing 20 has mounting screws 19.
It is also possible to use special mounting screws to secure the device. Moreover, although the screw hole 14 forms a screw receiver, this screw receiver may be provided in other parts of the coupling tool 13. Furthermore, the receiving plate 9 may be appropriately fixed to the bottom surface of the adjusting body 4 without using the groove 10.

According to the present invention, a vertical adjustment screw is provided between the connector and the adjustment body, and the installation can be adjusted within the length of this adjustment screw, so a large adjustment range can be secured. Since the adjustment screw can be rotated with a light force, the adjustment operation is easy, and since the screw portion can withstand a large load, the adjusted state can be maintained stably.
