The fixture described in Patent Document 1 includes a sash frame that is attached to an opening in a building, a shoji screen that is slidably attached to the sash frame, a handle that is attached to the inside of the shoji screen, a stopper that links to the handle, and a lock that stops at the stopper.

JP 2017-95923 A

According to the fittings described in Patent Document 1, the handle is attached to the vertical frame of a paper screen that is exposed to the outside air, and the locking part is located in a position where it is exposed to the outside air. Therefore, the heat of the outside air is transferred from the locking part to the handle, and there is a risk that the handle will become condensed when the outside temperature is low.

The purpose of this disclosure is to provide a fixture that prevents condensation on the handles attached to shoji screens.

In order to achieve the above-mentioned objective, the present disclosure provides a fitting comprising a shoji screen that slides relative to a sash frame, a handle for opening and closing the shoji screen, a handle fixing part that is attached to a vertical frame provided on the shoji screen and protrudes from a mounting surface facing the interior of the room, is located on the inner periphery of the mounting surface in the viewing direction and has a surface that intersects with the mounting surface, and fixes the handle to the surface that intersects with the mounting surface, a locking part that is provided on the handle fixing part and links to the handle, and a locking part that is fixed to the interior of the room than the interior surface of the vertical frame, and to which the locking part engages.

FIG. 2 is a plan cross-sectional view showing the structure of the fixture. FIG. 11 is a cross-sectional plan view showing the flow of outside air entering a fixture.

Below, we will explain the fittings according to an embodiment of the present invention with reference to the drawings.

As shown in FIG. 1, the fixture 1 comprises a sash frame 2, a shoji screen 10 attached to the sash frame 2, and a locking unit 20 for locking the shoji screen 10. The shoji screen 10 is, for example, a sliding door. The plan view will be described below.

The sash frame 2 is a frame that is attached to an opening in a building. The shoji screen 10 is attached to the sash frame 2 so that it can be opened and closed freely in a direction along the rail 3 (the x-axis direction in the figure). The shoji screen 10 slides relative to the sash frame 2. The shoji screen 10 is, for example, a double-glazed sash window with double glass panels G1 and G2.

The shoji screen 10 has a vertical frame 11 that contacts the vertical frame 2A of the sash frame 2 when closed. The vertical frame 11 is a frame member formed to extend in the up-down direction (z-axis direction in the figure). The vertical frame 11 is formed as a cylindrical body with a rectangular cross section. The vertical frame 11 is formed hollow by extrusion using aluminum material. The vertical frame 11 has a groove portion 12 for supporting the end of the glass sheet G. The vertical frame 11 has protrusions 11A and 11B that protrude toward the vertical frame 2A of the sash frame 2. Inside the vertical frame 11, a partition plate 13 that divides the internal space is formed along the x-axis direction. The partition plate 13 increases the strength of the vertical frame 11 and prevents the temperature of the outside air from propagating to the outside of the room.

A handle fixing part Q for fixing the handle P is attached to one end surface 14 of the vertical frame 11 facing the interior of the room. The handle fixing part Q is formed into a cylindrical body with a rectangular cross section. The handle fixing part Q is formed hollow by extrusion using aluminum material. This suppresses heat transmission from the shoji screen 10 to the handle P.

The handle fixing part Q has one end face Q2 formed facing the interior of the room. The handle fixing part Q has the other end face Q3 formed on the vertical frame 11 side opposite the one end face Q2. One side face Q4 and the other side face Q5 are formed facing each other in the perpendicular direction on both sides of the one end face Q2 and the other end face Q3. The other side face Q5 is formed on the vertical frame 2A side of the sash frame 2. The other end face Q3 of the handle fixing part Q is fixed to one end face 14 (mounting surface) of the vertical frame 11 by a screw Y or the like. The handle fixing part Q is fixed offset in the x-axis direction with respect to the vertical frame 11.

The handle fixing part Q is formed, for example, by combining a first member formed in an inverted L-shaped cross section with one end face Q2 and one side face Q4 integrally formed, and a second member formed in an L-shaped cross section with the other end face Q3 and the other side face Q5 integrally formed. The handle fixing part Q has a handle P fixed to one side face Q4 for opening and closing the shoji screen 10 from the inside of the room. The handle P is formed from a metal material or a resin material.

The handle P has a base end P1 fixed to one side Q4 of the handle fixing part Q. The handle P is fixed to a position on the side Q4 that is easy for a person to operate. The handle P is indirectly fixed to the vertical frame 11 via the handle fixing part Q. The handle P is disposed, for example, at a position at approximately the center height in the vertical direction of the one side Q4 of the handle fixing part Q. The handle P is formed by protruding from the base end P1 and bending so that the tip faces the inside of the room. The handle P is attached to the handle fixing part Q so that it can rotate freely around a rotation axis L that passes through the base end P1.

The handle P has its base end P1 connected to one end S1 of the shaft S by a screw T. The shaft S is rotatably attached to the handle fixing part Q. The shaft S rotates around a rotation axis L along the movement direction (x-axis direction) of the shoji 10. The other end S2 of the shaft S is formed with a locking part R that locks to the lock part 20. The locking part R is formed so that one end R1 is continuous with the other end S2 of the shaft S and the other end R2 protrudes from the other side surface Q5 of the handle fixing part Q. The locking part R is attached to the handle fixing part Q so as to be spaced away from one end surface 14 of the vertical frame 11 toward the inside of the room.

The engaging portion R has a claw portion (not shown) formed at its tip for engaging with the locking portion 20. The claw portion (not shown) rotates in conjunction with the rotation of the handle P. The claw portion (not shown) is inserted into the locking portion 20 when the screen 10 is in a closed state. The claw portion (not shown) is formed so as to be freely inserted and removed along the x-axis direction from a groove portion 23 formed in the locking portion 20 (described below) when the handle P is rotated to the unlocked position. The claw portion (not shown) is formed so as to be engaged with a groove portion 23 of the locking portion 20 (described below) when the handle P is rotated to the locked position.

The locking section 20 is fixed to the vertical frame 2A of the sash frame 2, spaced from one end face 14 (the surface facing the interior of the room) of the vertical frame 11 toward the interior of the room. The locking section 20 comprises a fixed base 21 fixed to the sash frame 2, and a locking member 22 fixed to the fixed base 21. The fixed base 21 is formed into a cylindrical body with a rectangular cross section. The fixed base 21 is formed hollow by extrusion using aluminum material. The fixed base 21 is formed on the vertical frame 2A of the sash frame 2, extending in the up-down direction.

The fixed base 21 has one end surface 21A facing the shoji screen 10, the other end surface 21B facing the one end surface 21A, and one side surface 21C and the other side surface 21D provided at both ends of the one end surface 21A and the other end surface 21B. The one side surface 21C and the other side surface 21D are formed in a direction perpendicular to the one end surface 21A and the other end surface 21B.

The fixed base 21 has a packing H attached to one end surface 21A, which fills the gap between the vertical frame 11. The packing H is made of an elastic material such as resin or rubber, which has a lower thermal conductivity than aluminum. The packing H is formed so as to deform upon point contact with the vertical frame 11. The fixed base 21 has one side surface 21C fixed to the sash frame 2. The fixed base 21 has a locking member 22 fixed to the other side surface 21D. The locking member 22 has one side surface fixed to the fixed base 21. The locking member 22 is formed in a rectangular parallelepiped. The locking member 22 has a groove portion 23 formed on the other side surface.

The groove 23 is formed so that the locking part R can be freely inserted and removed when the handle P is rotated to the unlocked position. The groove 23 is formed so that the locking part R can be locked when the handle P is rotated to the locked position.

As shown in FIG. 2, when the shoji screen 10 is closed, outside air A flows through the gap between the sash frame 2 and the vertical frame 11. Here, the area along the surface of the interior side of the shoji screen 10, including one end face 14 of the vertical frame 11, is the airtight line X. The outside air comes into contact with the protrusion 11A of the vertical frame 11, and the temperature is transmitted to the packing H. The packing H is formed so that the contact area with the protrusion 11A is small, so the temperature transmission is suppressed. The fixed base 21 to which the packing H is fixed is formed hollow, so the temperature transmitted from the packing H is suppressed from being transmitted to the locking member 22.

That is, because the locking unit 20 is separated from the airtight line X toward the indoor side, the outside air temperature is prevented from being transmitted to the locking unit 20. The engaging unit R, shaft S, and handle are attached to the handle fixing unit Q so as to be separated from the airtight line X toward the indoor side. Because the handle fixing unit Q is formed hollow, the outside air temperature is prevented from being transmitted to the handle P. Therefore, even when the outside air temperature is low and the temperature difference is large compared to room temperature, condensation on the handle P is prevented.

As described above, the fitting 1 prevents the temperature of the outside air from being transmitted to the handle P attached to the shoji screen 10, and prevents condensation on the surface of the handle P even when the outside temperature is low. The fitting 1 prevents the handle P from feeling cold even when touched when the outside temperature is low.

Although one embodiment of the present invention has been described above, the present invention can be modified or substituted as appropriate. For example, the structure for engaging the locking portion 20 with the engaging portion R is not limited to the above configuration, but may be composed of a cam and a latch.
