Description

[Detailed explanation of the idea] This invention relates to a building material adjusting device for fittings.

When installing shutters or other fittings, gaps may be created at window or doorway openings due to dimensional errors or distortions in the construction of the rectangular frame, where the fittings do not fit with the opening frame. In many cases, metal fittings, etc., are required to be adjustable.

Conventional building material adjustment devices involve screwing an abbreviated-shaped fixing fitting onto the inner surface of a vertical stile, screwing an adjustment screw into the horizontally protruding part of the fixing fitting, and touching the tip of the adjustment screw to the lower stile. A structure in which the lower stile can be adjusted vertically is generally known.

Although this conventional device has a simple structure, since the adjustment screw is supported only in two places, the adjustment screw may wobble when the screw is operated, making it difficult to perform the adjustment operation, or the wobbling may cause the threaded part and screw to sway. There is a high risk of deformation and damage to the mating hole, and this becomes more serious as the adjustment screw head moves away from the screw support.

Furthermore, since the tip of the adjustment screw is in direct contact with the stile etc., local deformation and damage to the stile etc. is caused, and rust and corrosion occur from the damaged portion.

In addition, if the weight of the fittings is large, due to the structure of the conventional device, the weight will be concentrated around the adjustment screw, which will not only cause the adjustment position of the building material to go out of order, but in severe cases, it will deform and become unusable. .

Furthermore, in the conventional device, an L-shaped connector is used to connect the vertical stile and the lower stile, and the horizontal part is fixed to the lower stile, and the vertical part is simply inserted into the vertical stile, and there is no need for adjustment. Since it is only in contact with the lower stile, there is no means of restraining the lower stile, and therefore there is a risk that the lower stile will come off and fall, which will hinder the adjustment work.

In this regard, in the conventional device, only forward rotation (clockwise rotation) of the adjusting screw is effective for adjusting the screw feed.

In other words, since the adjustment operation using the adjustment screw is effective only by pushing down the lower stile, it is difficult to make fine adjustments.

In addition, in other examples, in order to prevent the lower stile from falling, a through hole is provided on the outer surface of the stile, and a fixing screw is inserted through this hole to fix the L-shaped connector and the stile. Providing through holes on the outside surface is not desirable, as it allows rainwater to enter, leading to corrosion, and also makes it look unsightly.

On the other hand, the adjustment screw is relatively stable because it is supported at the hinge point, but this spasticity adjustment device requires an inner frame in addition to the lower frame, making the shutter heavy and costly. There are disadvantages such as being expensive.

This invention will be explained below with reference to illustrated embodiments.

First, a first example will be described. (Figures 1 to 5
(See figure) Figure 1 is an elevational view of the shutter 1.

The hollow vertical stile 2 and the lower stile 3 are connected by a synthetic resin-shaped corner block 4.

That is, the horizontal part 5 of the corner block 4 is screwed to the lower stile 3 with screws 56, and the vertical part 6 is slidably fitted inside the lower end of the vertical stile 2, whereby the lower stile 3 is attached to the vertical stile 2.
It is connected so that it can move up and down.

Note that the corner blocks 4 have the role of reinforcement as well as connection.

Further, the screws 56 that fasten the corner block 4 and the lower stile 3 with screws also fasten an auxiliary metal fitting 9, which will be described later, to the lower stile 3 with screws.

23 is a door roller.

In the above configuration, the spasticity adjusting device 7 is connected to the L-shaped fixture 8 fixed to the inner wall surface of the lower end of the vertical stile 2, the auxiliary bracket 9 (movable member) fixed to the lower stile 3, the fixture 8 and the auxiliary bracket 9. Adjustment screw 10, auxiliary metal fitting 9 and lower frame 3 installed over
It is composed of a synthetic resin type auxiliary block 11 (loosening prevention element) interposed between.

Then, the adjusting screw 10 is inserted into the screw 10 as shown in FIG.
a, and a non-threaded portion 16 having a smaller diameter than the threaded portion 10a and having no cage threads.

The support part 12 of the fixture 8 and the hook-shaped receiving part 13 provided at the upper end of the auxiliary fixture 9 are provided parallel to the lower stile 3 and facing each other.

The support part 12 has a long groove-shaped locking hole 14 cut out from the tip side.
Correspondingly, a tapped hole 15 is provided in the receiving portion 13.

A non-threaded portion 16 provided at the neck of the adjustment screw 10 is fitted into the locking hole 14 so as to be rotatable in the circumferential direction, so that the adjustment screw 10 can only rotate in the circumferential direction (that is, cannot move in the axial direction). Fixed.

The threaded part 10a is screwed into the threaded hole 15 of the receiving part 13, and by rotating the adjusting screw 10, the vertical movement of the lower stile 3 can be adjusted arbitrarily indirectly via the auxiliary metal fitting 9. ing.

In other words, the adjustment screw 10 connects the auxiliary metal fitting 9 and the fixing metal fitting 8 in a screwed state, so the lower stile 3 will not come off and fall, and depending on the rotation direction of the adjustment screw 10, the lower frame 3 will not fall off. The lower stile 3 can be moved up and down freely.

Further, protrusions 17.1 are provided at both ends of the receiving portion 13 of the auxiliary metal fitting 9.
8 is provided.

On the other hand, the protruding piece 17 (locking element) is engaged with a vertically elongated guide hole 19 (locking element) provided in the inner wall of the vertical stile 2 so as to be slidable up and down.

The long diameter of the guide long hole 19 is the threaded portion 1 of the adjustment screw 10.
The adjustment screw 10 is formed to be shorter than the length of 0a, and this restricts the amount of vertical movement of the auxiliary fitting 9.
Adjustment errors such as the lower stile 3 coming off due to excessive rotation can be prevented.

The other protruding piece 18 fits into the auxiliary block 11, thereby integrating the auxiliary block 11 and the auxiliary metal fitting 9.

The auxiliary block 11 has a protrusion 21 fitted between the support part 12 and the receiving part 13 on the upper part of the main body part 20.
0 is fitted between the receiving portion 13 and the lower stile 3, thereby dispersing the dead weight of the fittings transmitted via the adjusting screw 10.

Therefore, since the auxiliary block contacts the horizontal stile with a wide contact surface, the thrust of the adjustment screw 10 is effectively transmitted.
This contributes to preventing local deformation (bending, etc.) of the auxiliary metal fitting 9.

In addition, the auxiliary block 11 has a through hole or screw hole 22 that serves as a guide into which the adjustment screw 10 is inserted, thereby preventing the adjustment screw 10 from rattling in the lateral direction. This prevents local stress concentration (particularly on the neck of the adjustment screw) due to displacement of the adjustment screw 10.

Next, a second embodiment shown in FIGS. 6 to 10 will be explained.

FIG. 6 is an elevational view of the shutter 31. In the figure, 32 is a hollow vertical stile, 33 is a lower stile, and the vertical stile 32 and the lower stile 33 are connected by a corner block 34.

In the figure, 54 is a door roller. The corner block 34 is made of synthetic resin and is formed into a substantially rectangular shape with a horizontal portion 35 and a vertical portion 36.

The horizontal part 35 is fixed to the lower stile 33 with screws 53, and the vertical part 36 is slidably fitted inside the lower end of the vertical stile 32, thereby connecting the vertical stile 32 and the lower stile 33.

A building material adjustment device 37 is installed at a part of the corner of the vertical stile 32 and the lower stile 33.

The auxiliary metal fitting 39 has a mounting part 46 at the lower end, and a receiving part 47 located below and parallel to the support part 41 of the fixing metal fitting 38 at the upper end.
It is formed into a substantially U-shape.

A vertically elongated hole 48 is bored in the middle of the auxiliary metal fitting 39 in correspondence with the screw hole 44 of the fixing metal fitting 38.

The length of the major axis of this vertically elongated hole 48 is adjusted by the threaded portion 4 of the screw 40.
If the length corresponds to the length of 0 a, it is possible to restrict the vertical movement range of the lower stile 33 to the maximum, and it is possible to prevent the lower stile 33 from falling due to excessive turning of the adjustment screw 40.

The receiving portion 47 is provided with a screw hole 49 that communicates with the locking hole 43 of the fixture 38 .

Note that 50 is a through hole for tightening the screw 45.

The above-mentioned auxiliary metal fittings 39 are fixed to the lower frame 3 with screws at the mounting portion and are set upright.

At this time, the fixing screw 53 of the corner block 34 is also used for fixing.

The intermediate part of the auxiliary fitting 39 is attached to the bulging part 42,
At this attachment portion, a tightening screw 51 is screwed into the tapped hole 44 from the vertical hole 48, so that the auxiliary metal fitting 39 is fixed to the fixing metal fitting 38 so as to be movable up and down.

A non-threaded portion 52 is provided at the neck of the adjustment screw 40, and this non-threaded portion 52 is fitted into the locking hole 43 of the support portion 41, so that the adjustment screw 40 can only rotate in the circumferential direction (that is, cannot move in the axial direction). It is fixed as .

The threaded part 40 a of the adjustment screw 40 is the receiving part 4 of the auxiliary metal fitting 39
7 is screwed into the screw hole 49, thereby fixing the fixture 38.
The auxiliary fitting 39 is connected to its support portion 41 and receiving portion 47 so that the vertical distance can be adjusted.

In the figure, reference numeral 55 denotes an auxiliary block, which serves to prevent the adjustment screw 40 from rattling.
