DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an upper frame of a door shoji,
The present invention relates to a door shoji support tool for slidably supporting the inside of a groove formed on the lower surface of a Kamoi gate or along a rail protruding from the lower surface of a Kamoi gate.

[0002]

2. Description of the Related Art As shown in FIG. 6, a door shoji, such as a shoji or a sliding door, is provided with a ridge 12 continuously in a longitudinal direction of an upper end of an upper frame 10 corresponding to a horizontal frame at an upper end thereof. On the other hand, Kamoi 20 which is the horizontal pillar of the building supporting the upper frame 10 of the door shoji
In the longitudinal direction of the lower surface, a groove 22 for slidably inserting the protrusion 12 at the upper end of the upper frame is formed.

As shown in FIG. 7, a sliding door or other sliding door has a narrow groove 11 continuously formed in a longitudinal direction of an upper frame 10 corresponding to a horizontal frame at an upper end thereof. On the other hand, Kamoi 2 which is the horizontal pillar of the building supporting the upper frame 10 of the door shoji
In the longitudinal direction of the lower surface 0, a rail 24 is slidably fitted and locked inside the narrow groove 11 at the upper end of the upper frame 10.

[0004]

However, with the above-described support structure, the upper frame 10 of the door shoji is placed along the inside of the groove 22 formed on the lower surface of the Kamoi 20 or along the rail 24 protruding from the lower surface of the Kamoi 20. When slidably supported by
If the Kamoi 20 is longer than two spaces (approximately 3.6 m), etc., when the door shoji is moved left and right between the Kamoi 20 and the opposite threshold (not shown), The ridge 12 formed at the upper end of the frame 10 falls off from the inside of the groove 22 formed on the lower surface of the Kamoi gate 20, or the ridge 12 is formed on the lower surface of the Kamoi 20 from the inner side of the narrow groove 11 formed at the upper end of the upper frame 10 of the door. The protruding rail 24 has fallen off. Then, the door shoji cannot be smoothly moved to the left and right between the upper frame 10 and the opposing Kamoi 20 or the door shoji falls off the upper frame 10 and the opposing Kamoi 20. I have done it.

[0005] The reason is that Kamoi 20 is, as described above, 2
If the length is longer than the distance, the middle part of the gate 20 is largely bent downward. For this reason, the distance between the long dwelling gate 20 whose midway portion is greatly bent and the opposing sill greatly differs between the midway portion 20 and the midway portion and the end of the sill. Then, in order to move the door shoji smoothly between the long-formed Kamoi 20 and the threshold without any resistance, a gap between the upper end of the upper frame 10 and the lower end of the lower stile (not shown) of the door shoji is provided. The upper edge of the upper frame 10 of the door and the upper edge of the ridge 12 formed on the upper frame 10 so that the distance between the upper frame 10 and the lower frame 20 is substantially equal to the distance between the narrow gate 20 and the opposing sill. This is because the edge and the lower edge of the lower frame are cut off by a predetermined length. Then, the length of the entire door shoji is adjusted to be short. Alternatively, the distance between the upper end of the upper frame 10 and the lower end of the lower frame of the door shoji is substantially equal to the distance between the narrowly spaced Kamoi 20 portion and the opposing threshold portion. This is because the length is adjusted to be short. As a result, the upper end of the upper frame 10 of the sliding door and the upper end of the ridge 12 and the lower end of the lower frame 14 formed on the upper frame 10 with respect to the distance between the wide interval Kamoi portion 20 and the opposite sill portion. This is because the distance between them becomes too short. Then, when the door shoji was moved between the wide interval Kamoi portion 20 and the threshold portion, the protruded ridges 12 of the upper frame 10 of the door shoji were cut down and formed on the lower surface of the Kamoi 20. This is because they fall off from the inside of the groove 22. Alternatively, when the door shoji is moved between the wide interval Kamoi 20 portion and the threshold portion, the lower length of the door 11 is adjusted from the inside of the groove 11 formed at the upper end of the upper frame 10 of the door shoji whose length is adjusted to be low. This is because the rails 24 protruding from the rails fall off.

The present invention is intended to solve such a problem. Even when a door shoji is moved between a wide-spaced dwelling part and a threshold part facing the dwelling part, the dwelling part is not moved. It is an object of the present invention to provide a door shoji support that can reliably prevent a door shoji from falling off from a sill.

[0007]

In order to achieve the above object, a door shoji support according to the present invention is characterized in that the upper frame of the door shoji is formed by inserting the upper frame of the door shoji into the inside of a groove formed in the longitudinal direction of the lower surface of the Kamoi or the Kamoi.

A continuous groove formed in a loop shape, wherein a continuous groove for fitting and locking a rail protruding from the lower surface of the headgate is provided.

In this door shoji support, the base of the door shoji can be fixed upright on the upper end of the upper frame of the door shoji. And
The elevating unit, which is inserted vertically into the cylindrical space provided at the base and which can be moved up and down from the upper end opening thereof, can be brought up and down in the cylindrical space of the base. And the upper part of the raising / lowering part can be made to be able to protrude above the base or be buried inside the base.

In this case, an urging force for raising the elevating portion to raise the cylindrical space of the base above the base can be applied to the elevating portion by the urging means. Then, when the door shoji is moved between the wide gap of the gate section and the opposing threshold section, the lifting section and the cylindrical space of the base are urged in the direction of the Kamoi section located above it. By means, it can be raised above the base. Then, the upper part of the elevating part can be protruded long above the base in accordance with the height of the duck portion located above. Then, the raised upper part of the elevating part,
Along with the roller supported inside the recess at the upper end of the elevating unit, the roller can be appropriately fitted and locked into the inside of a groove formed on the lower surface of the duck portion located above the roller so that it does not easily fall off. Or, a roller supported inside the depression at the upper end of the elevating unit protruded long above the base, and located inside the continuous groove formed on the peripheral surface of the roller upper part protruded above the elevating unit, The rail protruding from the lower surface of the duck gate portion can be appropriately fitted and locked so that the rail does not easily come off and fall off.

[0010] Conversely, when the door is moved between the narrowly-spaced gate and the sill opposite to the door, the bottom of the groove engraved on the lower surface of the lower door is located below the door. The peripheral surface of the upper part of the roller protruding above the elevating unit can be pushed downward. Alternatively, the peripheral surface of the upper part of the roller protruding above the elevating unit can be pushed downward by the rail by projecting from the lower surface of the lower part of the lower part located below the lower part. Then, the elevating section supporting the roller is lowered to the inside of the base against the urging force of the urging means, by adjusting the cylindrical space of the base to the height of the duck portion located thereunder. Can be. Then, the upper part of the elevating part can be made to protrude shortly above the base in accordance with the height of the duck portion located therebelow. Then, the upper portion of the elevating portion that is protruded short, together with the roller supported inside the recess at the upper end of the elevating portion, is appropriately long so as not to easily fall off the inside of the groove formed on the lower surface of the duck portion located thereunder. It can be fitted and locked. Alternatively, the rail protruding from the lower surface of the duck portion located under the inside of the continuous groove formed in the roller peripheral surface supported inside the recess at the upper end of the raising and lowering which is shortly protruded above the base is easily removed. The length can be appropriately fitted and locked so as not to fall. And
It is possible to move the door shoji easily and laterally between the sill and the sill opposite the sill between the sill and the sill with a small resistance so as to prevent the sash from easily falling off the sill.

Further, when the door shoji is moved left and right between the gate and the threshold, a roller rotatably pressed against the inner bottom surface of the recess at the upper end of the elevating unit is frictionally attached to the inner bottom surface of the groove on the lower surface of the door. It can be rolled with low resistance. Alternatively, the roller rotatably supported inside the recess at the upper end of the elevating unit can be rolled on a rail protruding from the lower surface of the headgate with low frictional resistance. Then, the door shoji supported on the inside of the groove on the lower surface of the Kamoi through the roller, or the door shoji supported on the rail on the lower surface of the Kamoi through the roller, smoothly move to the left and right of the Kamoi with less frictional resistance. Becomes possible.
