Description

[Detailed description of the invention] (Industrial application field) The sliding door shoji installation adjustment device according to this invention is
This is to ensure that the height of the window frame and the height of the sliding door shoji have an optimal relationship when erecting the sliding door shoji inside the window frame.

(Prior Art) When installing a sliding door shoji inside a window frame, first, the upper end of the sliding door shoji is engaged with a guide rail of the upper frame constituting the window frame. Next, lift the sliding door shoji a little extra, move the door roller attached to the lower stile of the sliding door shoji directly above the lower rail provided on the top surface of the lower frame, and then lower the sliding door shoji a little, so that the door roller and lower rail are aligned. engage.

When installing such sliding door shoji,
It is necessary that the relationship between the height of the window frame and the height of the sliding door shoji is appropriate. In other words, if the height of the sliding door shoji is too large relative to the height of the window frame, it will not be possible to erect the sliding door shoji inside the window frame, and even if it is installed, it will not be possible to move the sliding door shoji smoothly. I find myself unable to do anything. Furthermore, if the height of the sliding door shoji is too small relative to the height of the window frame, the sliding door shoji will fall off from inside the window frame.

For this reason, the height of the door roller attached to the lower stile of the sliding door shoji has been made adjustable to optimize the relationship between the height of the window frame and the height of the sliding door shoji.

In this way, various structures have been known for adjusting the installation of sliding door shoji by adjusting the height of the door roller, but many of them are Since the height of the door roller was changed using a driver inserted through a hole formed in the door, the height could not be adjusted when the sliding door shoji was closed, and the adjustment work was not necessarily carried out smoothly. I couldn't do anything.

In order to eliminate this inconvenience,
Publication No. 65176 discloses a structure in which the height of a door roller attached to the lower stile of a sliding door shoji is adjusted by a driver inserted from above into a through hole drilled in the lower stile.

(Problems to be Solved by the Invention) However, even in the sliding door shoji installation adjustment device described in the above-mentioned publication, the following problems still occur.

In other words, in the case of soundproof or highly airtight sashes that have become popular in recent years, when the sliding door shoji is closed, the indoor sides of the upper, lower, left, and right frames that surround the sliding door shoji are pressed against the packing attached to the window frame. ing.

In this way, in the case of soundproofing or highly airtight sashes that press the interior side of each stile against the packing when closed, the sliding door shoji can be moved easily by separating the packing from the interior side of each stile except when closing. You need to be able to do it by force.

For this reason, various pulling mechanisms have been conventionally provided that move the sliding door shoji in parallel toward the indoor side in conjunction with the locking operation of the sliding door shoji, but when such a pulling mechanism is provided, Since the lower stile of the sliding door shoji and the lower rail of the window frame are displaced relative to each other when the sliding door shoji is pulled in, the structure of the door roller attached to the lower stile must be able to tolerate this displacement.

However, the door roller described in the above publication does not have a structure that can tolerate the above displacement, so it is not suitable for soundproofing or
Alternatively, when used in a highly airtight sash, it is necessary to devise a separate structure to allow for relative displacement between the lower stile and the lower frame, which complicates the overall structure of the sash. Things are unavoidable.

The sliding door shoji installation adjustment device of the present invention solves the above-mentioned inconveniences.

b. Structure of the invention (means for solving the problem) The sliding door shoji installation adjustment device of the present invention can freely adjust the height of the door roller attached to the lower stile of the sliding door shoji, just like the conventional adjustment device. By doing so, the height of the sliding door shoji can be adjusted to match the height of the window frame.

The door roller to be incorporated into the installation adjustment device of the present invention has a pair of hanging walls extending downward from both sides of the top plate on the bottom surface of the board, and one end edge of the top plate. By locking the outer casing, the outer casing is swingably suspended below the board, and elasticity is imparted to the outer casing in the direction in which the bottom surface of the board and the top surface of the top plate come into contact. .

The pivot shaft provided between the ends of the pair of hanging walls of the outer casing has a shaft extending downward from both sides of the top plate.
It supports one end of an inner casing that forms a pair of hanging walls, and a central axis that spans between the centers of both hanging walls that make up this inner casing is attached to the inside of this inner casing.
It supports the wheels so that they can rotate freely.

The inner casing is provided with a spring that tends to rotate the inner casing upward about a pivot at the end, so that the inner casing supporting the door roller rises unless an external force is applied.

In the installation adjustment device of the present invention, the base plate of such a door roller is fixed to the lower surface of the lower stile of the sliding door shoji, and the base plate is formed on one side of the horizontal part of the lower stile that the base plate is in contact with. An adjustment screw is screwed into the screw hole from above.

The lower end of this adjustment screw passes through a through hole formed in the top plate of the outer casing, and is brought into contact with the top surface of the top plate of the inner casing, so that the lower end of the adjustment screw passes through a through hole formed in the top plate of the outer casing, and is brought into contact with the top surface of the top plate of the inner casing, so that the lower end of the adjustment screw is inserted into the upper horizontal part that is above the horizontal part of the lower stile. is provided with a through hole through which a driver for rotating the adjustment screw can be freely inserted, and which is closed by the lid when not adjusted.

(Function) When adjusting the height of the sliding door shoji according to the height of the window frame using the sliding door shoji installation adjustment device of the present invention configured as described above, a hole is drilled in the upper horizontal part of the lower stile. By inserting a screwdriver into the through hole from above,
Rotate the adjustment screw that is screwed into the horizontal part of the lower stile or the screw hole of the board that makes up the door wheel.

As the adjustment screw rotates, the length of the adjustment screw protruding from the bottom surface of the board changes, and the inner casing with the bottom end of the adjustment screw in contact with the top surface of the top plate moves around the pivot at the end. It swings, and the height of the wheels rotatably supported by this inner casing changes.

When no external force is applied to the wheels, the bottom surface of the board and the top surface of the top plate of the outer casing are in contact with each other due to the elasticity applied to the outer casing, and the inner casing is also in contact with the top surface due to the elasticity of the spring. Since it is rotated upward, the wheels will not hang down and interfere with the installation work when the sliding door shoji is being installed.

When the sliding door shoji is locked and pulled toward the packing attached to the window frame, the lower stile of the sliding door shoji and the lower rail on the window frame side will be displaced relative to each other. Accordingly, the outer casing constituting the door roller swings around the engagement portion between one end edge of the top plate portion and the base plate. Due to this swinging, the relative displacement between the lower stile and the lower rail is absorbed, and the sliding door shoji can be pulled in with light force without adopting a particularly complicated structure.

(Example) Next, the present invention will be explained in more detail by explaining the illustrated embodiment.

Figures 1 to 5 show an embodiment of the present invention, and Figure 1 is a front view of a door roller to be incorporated into the installation adjustment device;
2 is a plan view of the same, FIG. 3 is a right side view of the same, FIG. 4 is a left side view of the same, and FIG. 5 is a longitudinal sectional side view showing the door roller attached to the lower stile of a sliding door shoji.

The door roller 1 to be incorporated into the sliding door shoji installation adjustment device of the present invention is made of a substrate 2 made of a highly rigid metal plate such as a steel plate.
A pair of inverted L-shaped locking pieces 3, 3 are formed at an interval on the bottom surface of the board 2 by bending a part of the board 2 at a substantially right angle.
The upper end of the outer casing 4 is suspended between them.

The outer casing 4 has a pair of hanging walls 6a, 6b extending downward from both side edges of a flat top plate 5, and between the pair of locking pieces 3, 3 is a top plate. Part 5
By inserting one end edge, the outer casing 4 can be attached to the board 2.
It is suspended from the bottom so that it can swing freely. Like this,
In order to allow the top plate portion 5 to be inserted between the pair of locking pieces 3, 3, notches 7, 7 are provided at the upper part of one of the pair of hanging walls 6a, 6b. By providing this, the width of the upper part of this hanging wall 6a is slightly narrowed.

A pair of hanging walls 6a, 6b forming the outer casing 4
A pivot shaft 9 is provided so as to span between the ends of the wheels 10, and this pivot shaft 9 supports one end of an inner casing 11 for rotatably supporting a wheel 10. This inner casing 11 has a pair of hanging walls 14, 14 formed downward from both side edges of a top plate part 13, which has a notch part 12 formed in the middle part for passing the wheel 10 through. The inner casing 1 is connected by a central shaft 15 extending between the central parts of both hanging walls 14, 14.
A wheel 10 fitted inside the wheel 1 is rotatably supported.

A tension spring 1 is attached to a locking portion 16 formed on the lower edge of the end of the inner casing 11 located on the opposite side to the pivot shaft 9.
The lower end of 7 is locked, and this tension spring 1
The upper end of 7 is locked to a locking part 18 formed on the bottom surface of the substrate 2. For this reason, the inner casing 11 is given elasticity that tends to rotate the inner casing 11 upward around the pivot shaft 9 at the end, and unless an external force is applied, the inner casing supporting the wheels 10 will move. 11
is in an increased state. Furthermore, this tension spring 1
The elasticity 7 is transmitted to the top plate 5 of the outer casing 4 through a bent piece 8 formed by bending and bending the edge of the top plate 13 of the inner casing 11 on the side opposite to the pivot 9. The upper surface of this top plate portion 5 and the lower surface of the substrate 2 are brought into elastic contact.

A screw hole 19 is formed in a portion near the end of the board 2 and located on the opposite side of the pivot shaft 9 provided in the outer casing 4, and an adjustment screw 20 is screwed into this screw hole 19 from above. ing. The lower end of the adjustment screw 20 protruding from the lower surface of the board 2 is inserted through a through hole 21 bored in the top plate portion 5 of the outer casing 4, which is swingably suspended below the board 2, and the outer By contacting the top surface of the top plate part 13 of the inner case 11 that is swingably supported inside the case 4, the adjustment screw 20 rotates.
The inner casing 11 is made to swing around a pivot 9.

The door roller 1 to be incorporated into the construction adjustment device of the present invention is as follows:
Although it is configured as described above, when configuring the installation adjustment device, as shown in FIG.
By fixing to the lower surface of the intermediate horizontal part 24 of the lower stile 2
Attach door roller 1 to the inside of 3.

When performing this installation work, the adjustment screw 20 is pulled out from the screw hole 19 of the board 2, and after the board 2 is fixed to the intermediate horizontal part 24 of the lower frame 23, the adjustment screw 20 is screwed into the screw hole 19. The lower end of this adjustment screw 20 is brought into contact with the upper surface of the top plate part 13 of the inner casing 11, or as shown in the figure,
4 is provided with a through hole 26 through which the head 20a of the adjusting screw 20 can freely pass.

By rotating the adjustment screw 20 of the door wheel 1 attached to the lower stile 23 of the sliding door shoji 22 in this way,
In order to be able to adjust the height position of the wheels 10 even after fixing the base plate 2 to the intermediate horizontal portion 24, an upper horizontal portion 25 located above the intermediate horizontal portion 24 of the lower stile 23 is A through hole 27 is provided through which a driver for rotating the adjustment screw 20 can be inserted. This through hole 27 is closed with a cover body 28 made of an elastic material such as rubber during non-adjustment when there is no need to insert the driver.

The sliding door shoji 22 is assembled with the sliding door shoji 22 by the sliding door shoji installation adjustment device of the present invention, which is constructed by assembling the door roller 1 configured as described above to the lower stile 23 of the sliding door shoji 22 as described above.
When adjusting the height to match the height of the window frame, remove the lid 28 that covers the through hole 27 bored in the upper horizontal part 25 of the lower stile 23, and insert a screwdriver inserted into the through hole 27 from above. Accordingly, the board 2 that constitutes the door roller 1
The adjustment screw 20 screwed into the screw hole 19 is rotated.

As the adjustment screw 20 rotates, this adjustment screw 2
0 protrudes from the bottom surface of the board 2, and the inner casing 11 in which the lower end of the adjustment screw 20 is brought into contact with the upper surface of the top plate part 13 is attached to a pivot shaft that pivots the end of the inner casing 11. The height of the wheel 10, which swings about 9 and is rotatably supported by this inner casing 11, changes.

The end of the inner casing 11 opposite to the pivot 9 is pulled upward by the elasticity of a tension spring 17, and supports the wheel 10 when no external force is applied to the wheel 10. The inner casing 11 and the outer casing 4 fitted with this inner casing 11 have a tension spring 17.
Since the lower surface of the substrate 2 and the upper surface of the top plate portion 5 of the outer casing 4 are maintained in the raised state by the elasticity of For this reason, the sliding door shoji 22 is placed inside the window frame.
When erecting, the wheels 10 will not hang down below the lower stile 23 and will not interfere with the erecting work.

By locking the sliding door shoji 22, when the sliding door shoji 22 is pulled toward the packing attached to the window frame to the right in FIG. 5, the lower stile 23 of the sliding door shoji 22 and the lower rail 29 on the window frame side are displaced relative to each other.

As the lower stile 23 of the sliding door shoji 22 and the lower rail 29 on the window frame side are displaced relative to each other in this way, the fifth
As shown in the figure, the outer casing 4 constituting the door roller 1 swings around a support section formed by a pair of locking pieces 3, 3 provided on the base plate 2. Due to this swing, the lower stile 2
3 and the lower rail 29 is absorbed.
Even when the outer casing 4 swings in this way, the board 2
Since it is immovable, the adjustment screw 20 screwed onto this board 2 will not swing. For this reason, the size of the through hole 26 bored in the top plate portion 5 of the outer casing 4 is determined by the adjustment screw 20.
It is sufficient to make it slightly larger than the outer diameter of the When the adjustment screw 20 is screwed onto the outer casing 4 side as in the structure described in the above-mentioned publication, the adjustment screw 20 swings greatly when the outer casing 4 swings.
It becomes necessary to form the through hole through which the screw 0 is inserted considerably larger than the outer diameter of the adjusting screw 20.

For this reason, the sliding door shoji 22 is pulled in by the lower rail 2.
This can be done with light force without adopting a particularly troublesome structure such as changing the shape of 9.

c. Effects of the invention Since the sliding door shoji installation adjustment device of the present invention is configured and operates as described above, it is not only possible to adjust the sliding door shoji installation with the sliding door shoji closed. , applied to soundproofing or highly airtight sashes, it becomes possible to pull the sliding door shoji with light force without adopting a troublesome structure.
