Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to a door installation adjustment device.

[Conventional technology]

Generally, after years of use, the tip of a door may sag under its own weight, making it impossible to open and close smoothly, and it is necessary to adjust the installation each time as necessary.

Conventionally, this type of installation adjustment involves screwing an adjustment screw onto the tip of the door upper stile so that the tip comes into contact with the top edge of a panel such as glass in the door frame, and then adjusting the adjustment screw by rotating it. It used force to correct the sagging of the tip of the door.

[Problem that the invention attempts to solve]

However, although this type of construction adjustment is sufficient for relatively small doors such as doors for residential buildings, it may not be structurally possible to use for large doors used for entrances and exits of department stores, etc. There is. Since large type doors are generally quite heavy, simply connecting the upper and lower horizontal stiles and the left and right vertical stiles with screws is not strong enough, so the upper and lower horizontal stiles and the left and right vertical stiles are connected inside the upper and lower horizontal stiles. Insert the connecting bolt into the
This is because it is connected by connecting both ends to the left and right stiles.

This invention was mainly devised for this type of door, and can also be used for large type doors, and is a door installation adjustment that makes it extremely easy to adjust the installation of this type of door. The purpose is to provide

[Means for solving problems]

In this invention, an outer metal fitting is provided in the tip of the upper door stile, and a rectangular cylindrical inner metal fitting that penetrates the door upper stile in the longitudinal direction is disposed inside the outer metal fitting so as to be movable up and down.
and vertically threading an adjustment screw into the upper end of the outer metal fitting, and abutting the tip of the adjustment screw against the inner metal fitting;
Furthermore, the above object is achieved by attaching a shaft member to the lower end of the inner fitting with its tip end in contact with the upper end of the panel within the door frame.

〔Example〕

Hereinafter, this invention will be explained with reference to an illustrated embodiment.
4, a connecting bolt 6 is inserted into the hollow part 5 of the upper and lower horizontal frames 2, 3 having a rectangular cross section, and both ends of the connecting bolt 6 are passed through both the upper and lower ends of the left and right vertical frames 4, 4. They are connected by screwing a connecting nut 7 into the male threaded portion 6a of the penetrating portion. A panel 18 made of glass or the like is fitted between the upper and lower horizontal frames 2 and 3 and the left and right vertical frames 4 and 4.

Inside the hollow part 5 at the tip of the upper stile 2 is an installation adjustment device A.
is provided. Installation adjustment device A is external metal fitting 8
It consists of an inner metal fitting 9 inside this outer metal fitting 8.

The outer fitting 8 is one size smaller than the inner diameter of the hollow part 5, and has an upper wall 8a, side walls 8a extending from both sides of the upper wall 8a,
It is formed in a groove-shaped cross section that opens downward from 8b.

Further, vertically long guide grooves 10, 10 are formed in the center of both side walls 8b, 8b of the outer metal fitting 8, and a plurality of protrusions 1 are formed on both sides of the guide grooves 10, 10.
1 and 11 are provided in contact with the inner surface of the hollow part 5 of the upper stile 2, so that the outer metal fitting 8 does not wobble within the hollow part 5.

Further, a screw hole 12 is formed in the center of the upper wall 8a of the outer fitting 8. And this screw hole 1
2, an adjusting screw 13 is vertically screwed through a through hole 14 bored in the upper surface of the hollow part 5 of the upper stile 2 in correspondence with the screw hole 12. The tip of the adjustment screw 13 is
It passes through the screw hole 12 and abuts against the center of the upper surface of the inner fitting 9.

The inner metal fitting 9 is formed into a substantially rectangular square tube shape that has an inner diameter approximately equal to the inner diameter of the outer metal fitting 8 and extends through the upper stile 2 in the longitudinal direction. The connecting bolt 6 passes through the hollow part of the inner fitting 9 at the tip of the upper frame 2. In addition, guide pieces 1 are provided at the center of both sides of the inner fitting 9.
5, 15 are formed, and the guide pieces 15, 15 are engaged with the guide grooves 10, 10. The inner fitting 9 can be smoothly moved up and down by the functions of the guide groove 10 and the guide piece 15.

Furthermore, a shaft member 16 of a predetermined length is attached to the center of the lower end of the inner fitting 9 so as to hang vertically.

The tip of the shaft member 16 protrudes to the outside of the hollow portion 5 through a through hole 17 formed in the bottom surface of the hollow portion 5 of the upper stile 2 corresponding to the shaft member 16, and comes into contact with the upper end surface of the panel 18. There is.

Note that a buffer cap 19 made of a soft material such as rubber is attached to the shaft member 16.
This prevents damage to the panel 18 due to

In such a configuration, when the adjusting screw 13 is rotated in the screwing direction, the inner fitting 9 engages the guide groove 1 of the outer fitting 8.
The shaft member 16 is guided by 0 and 10 and descends downward.
Since the tip of presses the tip of the panel 18,
As a result, only the upper and lower horizontal stiles 2 and 3 and the door end side vertical stile 4 move upward, and the sagging of the front end of the door 1 can be corrected.

[Effect of idea]

Since this invention consists of the above configuration, it produces the following results.

It can also be used for large-sized doors that have connecting bolts inserted into the upper and lower horizontal stiles to connect the upper and lower horizontal stiles and the left and right vertical stiles, and it is also extremely easy to correct the sagging of these types of doors. can do.

Furthermore, even if the cross-sectional size of the upper stile of the door changes, it can be handled simply by changing the length of the adjustment screw, making it extremely adaptable.

Furthermore, installation is extremely simple as it can be installed by simply forming holes in the upper and lower parts of the upper stile.
