Description

The present invention relates to a fitting in which a shoji is attached to the opening of an opening frame so as to be openable and closable.

In recent years, a composite structure opening frame in which a resin frame material is attached to the indoor side of a metal frame material has been adopted in many fittings for heat insulation performance and prevention of dew condensation. For example, Patent Document 1 discloses a fitting for a vertical sliding window having a structure in which a shoji is attached to an opening frame having a composite structure so as to be openable and closable toward the outdoor side.

In such a vertical sliding window or a fitting for a sliding window, a receiving component for receiving a latch piece of a cam latch handle provided on a shoji is attached to an opening frame. In the configuration of Patent Document 1, the receiving component is attached to the indoor side finding surface of the hollow portion formed in the resin frame material, and this indoor side finding surface is configured as the lock surface of the latch piece (lock member).

Japanese Unexamined Patent Publication No. 2014-163077

However, in the configuration of Patent Document 1, since the indoor side finding surface of the hollow portion formed in the resin frame material is used as the lock surface, the size of the hollow portion cannot be expanded in the prospective direction. That is, the hollow portion is a portion that becomes a heat insulating layer of the resin frame material, and its size greatly affects the heat insulating performance. However, in the configuration of Patent Document 1, the expected size of the hollow portion must be set to the minimum, and the improvement of the heat insulating performance is limited. Moreover, in the configuration of Patent Document 1, since the latch piece is arranged on the indoor side finding surface of the resin frame material, the number of parts when viewed from the indoor side is large, and the appearance quality is low.

The present invention has been made in consideration of the above-mentioned problems of the prior art, and secures the heat insulating performance and the appearance quality while attaching the receiving component for the lock member to the opening frame of the composite structure using metal and resin. The purpose is to provide fittings that can be used.

The fitting according to the present invention is a fitting in which a shoji holding a face material with a frame is attached to the opening of the opening frame so as to be openable and closable, and the shoji moves forward and backward from the frame toward the opening frame. A receiving component having a possible locking member and locking the locking member abuts on a wall portion forming a prospective surface of the opening, and partly in a space formed on the back side of the wall portion. It is installed in a buried state, and is characterized in that a rib protruding toward the opening is provided on the indoor side finding surface constituting the space.

According to the present invention, it is possible to sufficiently expand the expected dimensions of the hollow portion provided in the resin frame material to sufficiently secure the heat insulating performance and secure the installation space for the receiving parts. Moreover, when viewed from the indoor side, the receiving parts and the locking members locked to the receiving parts are not conspicuous, and the appearance quality is high.

In this embodiment, a fitting 10 for a vertically sliding window in which a shoji screen 14 is vertically slid out to the outside of the room in the prospective direction of a vertically long opening frame 12 is illustrated.

The opening frame 12 is formed by forming a rectangular opening 13 by framing the upper frame 12a, the lower frame 12b, and the left and right vertical frames 12c and 12d in four directions. The opening frame 12 has a composite structure in which a metal frame material 16 arranged on the outdoor side and a resin frame material 18 arranged on the indoor side are combined (see FIGS. 2 and 3). The metal frame material 16 is an extruded metal frame material such as aluminum. The resin frame material 18 is an extruded profile material of a resin such as vinyl chloride resin (PVC).

In the present application, the prospective direction means the indoor / outdoor direction of the fitting 10 (the direction indicated by the arrow Z in the figure), and the prospective plane means a plane extending along the prospective direction. The finding direction is a direction orthogonal to the prospective direction, and in the case of vertical frames 12c, 12d, etc., which are long in the vertical direction, the vertical direction (the direction indicated by the arrow Y in the figure) which is the longitudinal direction thereof, and the horizontal direction. In the case of a long upper frame 12a, lower frame 12b, etc., it means the left-right direction (direction indicated by the arrow X in the figure) which is the longitudinal direction thereof. The finding surface is a surface along the finding direction. The inside (inner circumference) of the opening frame 12 means the portion on the opening 13 side where the shoji 14 is arranged, and the outside (outer circumference) of the opening frame 12 means the portion on the opposite side of the opening 13 side. ..

The upper frame 12a is obtained by assembling the resin upper frame 18a of the resin frame material 18 to the metal upper frame 16a of the metal frame material 16. The lower frame 12b is formed by assembling the resin lower frame 18b of the resin frame material 18 to the metal lower frame 16b of the metal frame material 16. The vertical frames 12c and 12d are formed by assembling the resin vertical frames 18c and 18d of the resin frame material 18 to the metal vertical frames 16c and 16d of the metal frame material 16, respectively. Each of the frames 12a to 12d is fixed to the building frame by using a fixing tool 20 such as a nail or a screw.

As shown in FIG. 2, in the metal upper frame 16a, the resin upper frame 18a is mounted on the indoor side portion of the inner prospective surface 22. The outdoor portion of the inner prospective surface 22 is the shoji arranging portion 23 in which the shoji 14 is arranged. The metal upper frame 16a has a protruding piece 24 protruding inward from substantially the center of the inner prospective surface 22 in the indoor / outdoor direction, and an engaging portion 25 provided at the indoor side end portion of the inner prospective surface 22.

The resin upper frame 18a has an engaging portion 26 provided at the outdoor end portion of the outer prospective surface, and a protruding piece 27 protruding outward from the indoor side end portion of the outer prospective surface. The engaging portion 26 and the protruding piece 27 are engaged with the protruding piece 24 and the engaging portion 25 of the metal upper frame 16a, respectively. As a result, the resin upper frame 18a is connected to the metal upper frame 16a. In the resin upper frame 18a, the inside prospective surface of the opening frame 12, that is, the prospective surface 28 of the opening 13 is formed by the wall portion of the hollow portion 29. The outdoor finding surface 30, which is the outdoor wall of the hollow portion 29, serves as a door stop for the shoji 14 arranged in the shoji arranging portion 23.

As shown in FIG. 2, the shoji arranging portion 23, the protruding piece 24, and the engaging portion 25 are also provided on the inner prospective surface 22 of the metal lower frame 16b. The engaging portion 26 and the protruding piece 27 are also provided on the prospective surface 28 of the resin lower frame 18b. The resin lower frame 18b does not have a hollow portion 29, and its outdoor side finding surface 30 serves as a door stop for the shoji 14.

Ribs 32 protruding inward toward the opening 13 are provided at the inner peripheral side ends of the indoor side finding surfaces 31 of the resin vertical frames 18c and 18d. The rib 32 extends over the entire length of the resin vertical frames 18c and 18d.

One vertical frame 12d is on the door end side of the shoji 14. In the resin vertical frame 18d constituting the vertical frame 12d, the receiving component 34 is attached to the prospective surface 28 formed by the wall portion of the hollow portion 29. The receiving component 34 is a metal fitting for locking the latch piece (lock member) 35a of the cam latch handle (cam latch) 35 provided on the shoji 14.

FIG. 4 is an enlarged exploded perspective view of a main part showing the mounting structure of the upper frame 12a and the vertical frame 12d.

As shown in FIG. 4, in the vertical frame 12d, the upper end portion of the prospective surface 28 is cut out by the notch portion 28a. A wall portion forming the hollow portion 29 of the upper frame 12a is inserted into the notch portion 28a. As a result, the upper frame 12a and the vertical frame 12d are connected in a state where the end portion of the upper frame 12a is hidden behind the indoor side finding surface 31 of the vertical frame 12d (see FIG. 1). At this time, since the rib 32 extends over the entire length of the vertical frame 12d, the rib 32 also hides the upper frame 12a. The connection structure between the other end of the upper frame 12a and the vertical frame 12c is the same, and the connection structure between both ends of the lower frame 12b and the vertical frames 12c and 12d is also the same. That is, the opening frame 12 has a vertical winning frame structure in which the upper frame 12a and the lower frame 12b, which are horizontal frames, are in-row coupled inside the vertical frames 12c and 12d.

The shoji 14 has a structure in which the face material 38 is held by the frame 36.

The face material 38 is a two-layered double glazing in which a pair of glass plates 38a and 38b are arranged facing each other at a distance from each other via a spacer 39. The face material 38 may be composed of one layer or three or more layers of glass plates.

The stile body 36 holds the face material 38 by assembling the upper stile 36a, the lower stile 36b, and the vertical stiles 36c and 36d in four directions.
