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

  In recent years, an opening frame having a composite structure in which a resin frame material is mounted on the interior 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 in which a shoji is attached to an opening frame of a composite structure so as to be openable and closable toward the outdoor side.

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

JP, 2014-163077, A

  However, in the configuration of Patent Document 1 described above, since the indoor-side finding surface of the hollow portion formed in the resin frame material is 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 serves as 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 dimension of the hollow portion must be set to the minimum, and the improvement of the heat insulation 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 while securing the heat insulating performance and the appearance quality while mounting the receiving component for the lock member in the opening frame of the composite structure using metal and resin. The object is to provide a fitting that can be used.

  The fitting according to the present invention is a fitting in which a shoji holding a face material by a frame is attached to the opening of the opening frame so as to be openable and closable, and the shoji advances and retreats from the frame toward the opening frame. A receiving part that has a lockable member and that locks the lock member is brought into contact with a wall that forms the prospective surface of the opening, and a part of the receiving part is provided in a space formed on the back side of the wall. It is characterized in that it is installed in a buried state, and a rib that projects toward the opening is provided on the indoor-side finding surface that constitutes the space.

  ADVANTAGE OF THE INVENTION According to this invention, the prospective dimension of the hollow part provided in a resin frame material can be fully expanded, sufficient heat insulation performance can be ensured, but the installation space of a receiving component can be ensured. Moreover, when viewed from the inside of the room, the receiving part and the lock member locked to the receiving part are not conspicuous, and the appearance quality is high.

  As shown in FIGS. 1 to 3, the fitting 10 includes an opening frame 12 that is fixed to an opening of a building frame, and a shoji 14 that is openably and closably attached to the opening 13 of the opening frame 12. This embodiment exemplifies a fitting 10 of a vertical sliding window in which a shoji 14 is vertically slidable to the outside of the vertically long opening frame 12 in the prospective direction.

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

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

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

  As shown in FIG. 2, the metal upper frame 16a has a resin upper frame 18a attached to the indoor side portion of the inner prospective surface 22. The outdoor side portion of the inner prospective surface 22 becomes a shoji disposing portion 23 in which the shoji 14 is arranged. The upper metal frame 16 a has a projecting piece 24 that projects inward from a substantially center of the inner prospective surface 22 in the indoor / outdoor direction, and an engagement portion 25 provided at the indoor end of the inner prospective surface 22.

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

  As shown in FIG. 2, the shoji disposing 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 the hollow portion 29, and the outdoor-side finding surface 30 serves as a door stop for the shoji 14.

  As shown in FIG. 3, the shoji disposing portion 23, the protruding piece 24, and the engaging portion 25 are also provided on the inner prospective surface 22 of the metal vertical frames 16c and 16d. The engagement portion 26, the protruding piece 27, the hollow portion 29, and the outdoor side finding surface 30 are also provided on the prospective surface 28 of the resin vertical frames 18c and 18d. A rib 32 that projects inward toward the opening 13 is provided at an inner peripheral side end of the indoor-side finding surface 31 of each 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 screen 14. In the resin vertical frame 18d forming the vertical frame 12d, the receiving component 34 is attached to the prospective surface 28 formed by the wall of the hollow portion 29. The receiving part 34 is a metal fitting that locks a latch piece (lock member) 35a of a cam latch handle (cam latch) 35 provided on the shoji screen 14.

  FIG. 4 is an enlarged exploded perspective view of a main part showing a 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 of the prospective surface 28 is notched by the notch 28a. The wall portion forming the hollow portion 29 of the upper frame 12a is inserted into the cutout portion 28a. As a result, the upper frame 12a and the vertical frame 12d are connected in a state where the end 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 also 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. In other words, the opening frame 12 has a vertical win frame structure in which the upper frame 12a and the lower frame 12b, which are horizontal frames, are inlay-connected inside the vertical frames 12c and 12d.

  The shoji screen 14 has a structure in which a frame 38 holds a face member 38.

  The frame 36 is formed by assembling an upper frame 36a, a lower frame 36b, and vertical frames 36c and 36d around four frames to hold a face member 38. Each of the frames 36a to 36d has a composite structure in which a resin frame member 41 serving as a ridge is mounted on the indoor side of the metal frame member 40 arranged on the outdoor side. The metal frame member 40 is an extruded shape member made of metal such as aluminum. The resin frame member 41 is an extruded shape member of resin such as vinyl chloride resin (PVC).

  The frame body 36 holds the outer peripheral edge portion of the face material 38 in an inward opening groove 42 formed by the metal frame material 40 and the resin frame material 41 of each of the frames 36a to 36d. A gasket 44 is interposed between the opening groove 42 and the face material 38.

  The shoji 14 can be opened and closed in a prospective direction by connecting the upper frame 36a and the lower frame 36b to the upper frame 12a and the lower frame 12b via the arm 45, respectively. The shoji 14 has one vertical frame 36c on the suspension base side and the other vertical frame 36d on the door tip side. A handle base 46, which rotatably supports the cam latch handle 35, is connected to the indoor-side finding surface of the resin frame member 41 which constitutes the vertical frame 36d on the door end side. The cam latch handle 35 is manually rotated to move the cam latch handle 35 forward and backward toward the vertical frame 18d facing the latch piece 35a at the tip. Thereby, the shoji 14 can be locked by closing the shoji 14 and locking the latch piece 35a to the receiving part 34.

  As shown in FIGS. 2 and 3, the fitting 10 includes a screen door device 48 capable of opening and closing the indoor side of the opening 13 of the opening frame 12. The screen device 48 is provided on the indoor side of the prospective surface 28 of each of the frames 18a to 18d. In the case of the present embodiment, the screen door device 48 is a raising / lowering roll screen door capable of winding and delivering the net 48b by the upper rotary roll 48a. The screen door device 48 has left and right vertical rails 48c that guide the screen 48b so as to be vertically movable. The left and right vertical rails 48c are fixed to the indoor-side finding surfaces 31 of the indoor-side walls that form the hollow portions 29 of the resin vertical frames 18c and 18d using double-sided tape or the like. The screen door device 48 is not shown in FIG.

FIG. 6 is an enlarged perspective view of an essential part showing the mounting structure of the cam latch handle 35 and the receiving component 34.

  As shown in FIGS. 5 and 6, the handle base 46 of the cam latch handle 35 is attached to the inner surface of the resin frame member 41 with the liner plate 50 interposed therebetween. A pair of upper and lower hole portions 51 are formed on the indoor side finding surface of the resin frame member 41. The liner plate 50 is also formed with holes 50a having the same pitch as the pair of holes 51. An L-shaped back plate 52 is fixed to the metal frame member 40 with screws on the rear surface (on the side of the opening groove 42) of the resin frame member 41 on the indoor side (see FIG. 3). The cam latch handle 35 is attached and fixed to the frame body 36 by fitting a pair of bosses 52a of the back plate 52 into the handle base 46 through the holes 51 and 50a and fixing them with screws.

  The receiving part 34 is a metal fitting having a case 34b having a surface plate 34a and an arcuate concave portion 34c opening in the surface plate 34a. The surface plate 34a is arranged on the prospective surface 28 of the resin vertical frame 18d. A mounting hole 54 communicating with the hollow portion 29 is formed in the prospective surface 28. Locking protrusions 34d are formed on both side surfaces of the case 34b in the prospective direction. The case 34b is arranged in the hollow portion 29 through the mounting hole 54. Further, the surface plate 34a is placed on the prospective surface 28, and the locking projection 34d is locked on the back surface of the wall portion of the resin vertical frame 18d having the mounting hole 54 formed therein. As a result, the receiving component 34 is attached and fixed to the resin vertical frame 18d by snap-in.

  As described above, the fitting 10 according to the present embodiment is a shoji that holds the face member 38 with the frame 36 with respect to the opening 13 of the opening frame 12 in which the resin frame member 18 is mounted on the indoor side of the metal frame member 16. This is a configuration in which 14 is attached so as to be openable and closable. In the fitting 10, the shoji 14 has a latch piece 35a that is a lock member that can advance and retreat from the frame 36 toward the opening frame 12, and the resin frame member 18 has a hollow portion 29 and the opening portion 13 of the opening portion 13. A receiving component 34 for locking the latch piece 35a is attached to the wall of the hollow portion 29 forming the prospective surface 28.

  In this manner, the fitting 10 mounts the receiving component 34 that locks the latch piece 35 a on the shoji 14 side to the wall of the hollow portion 29 that forms the prospective surface 28 of the opening 13. For this reason, it is possible to secure an installation space for the receiving component 34 while sufficiently enlarging the prospective dimension of the hollow portion 29 and sufficiently securing the heat insulating performance. In addition, since the fitting 10 is provided with the receiving component 34 on the prospective surface 28, the receiving component 34 and the latch piece 35a engaged with the receiving component 34 are not conspicuous when viewed from the indoor side, and the appearance quality is high.
