Summary of the Invention
Problems to be Solved by the Invention
[0004] In the case of the above-described fitting, when mounting the screen door, it is not possible to visually check the engaging groove of the lower frame and the engaging fin portion on the lower frame side, and there may be a case where it cannot be confirmed that the engaging fin portion on the lower frame side is accommodated in the engaging groove of the lower frame. At this time, when there is a portion that protrudes toward the indoor side from the engaging fin portion, there is a problem that the engaging fin portion on the lower frame side may not be accommodated in the engaging groove, and the lower frame may be placed on the portion that protrudes toward the indoor side of the engaging fin portion and may not be correctly mounted.
[0005] The present invention has been made in view of such problems, and an object thereof is to provide a fitting in which a screen door mounted in a cantilevered manner is more reliably mounted.
Means for Solving the Problem
[0006] The main invention for achieving such an object is a fitting having a screen door mounted in a cantilevered manner on the indoor side of a window frame, and having a regulating member attached to a lower frame constituting the window frame to regulate the mounting position of the screen door. The lower frame has a prospective surface along the prospective direction, a screen door mounting piece protruding upward from the prospective surface on which the screen door is placed, and a protruding portion protruding toward the indoor side from the prospective surface inside the screen door mounting piece. The regulating member has a regulating member finding surface disposed on the indoor side of the protruding portion, and an indoor inclined surface that is connected above the regulating member finding surface and has an inclination that decreases in height toward the indoor side. The lower frame constituting the screen door has a recess provided at the lower end and recessed upward into which the screen door mounting piece is inserted, and a guide piece that is connected to the recess and extends toward the outdoor side to guide the screen door mounting piece into the recess. The distance in the prospective direction between the indoor side end of the recess and the lower end of the guide piece is narrower than the distance in the prospective direction between the regulating member finding surface and the indoor side end of the protruding portion. The fitting is characterized by this. Other features of the present invention will be clarified by the description in this specification and the attached drawings.

The lower prospect surface portion 17a has an overhanging portion 17c overhanging indoor - side from the upward protruding piece 17b, and a lower finding surface portion 17d having a finding surface extending downward from the indoor - side end of the overhanging portion 17c and facing indoor is provided.
[0015] As shown in Fig. 1, regulating members 5 for preventing mis - installation of the screen door 4 are provided at both ends in the left - right direction of the lower finding surface portion 17d. The regulating member 5 has an indoor regulating portion 5a disposed on the indoor - side of the lower finding surface portion 17d of the indoor lower frame 17, and an upper regulating portion 5b connected to the indoor regulating portion 5a and located above the lower prospect surface portion 17a.
[0016] As shown in FIGS. 4 and 5, the indoor regulating part 5a has a fitting piece 5c that protrudes to the outdoor side and fits into a fitting hole (not shown) provided in the lower finding surface part 17d. When the fitting piece 5c fits and is attached to the lower finding surface part 17d, a regulating member finding surface 5d is formed on the indoor side from the lower finding surface part 17d.
[0017] The upper regulating part 5b is provided so as to cover the indoor part of the protruding part 17c connected from the regulating member finding surface 5d. The upper regulating part 5b has an indoor inclined surface 5e and an outdoor inclined surface 5f whose heights decrease from approximately the center in the prospective direction toward the indoor side and the outdoor side, respectively.
[0018] As shown in FIG. 3, the indoor vertical frame 19 is an extrusion-shaped member with the vertical direction as the extrusion direction and has a vertical finding surface part 19a having a finding surface facing the indoor side. The vertical finding surface part 19a faces the vertical frame 42 of the attached screen door 4 in the prospective direction.
[0019] As shown in FIGS. 1 and 2, the screen door 4 has a frame body 43 in which an upper frame 40, a lower frame 41, and left and right vertical frames 42, all of which are extrusion-shaped members with the longitudinal direction as the extrusion direction, are framed in a rectangular shape, and a net material 44 is stretched across the opening inside the frame body 43. At the upper end of the upper frame 40, there are an upper wall part 40a having a finding surface facing the upper frame 11 over substantially the entire width in the left-right direction, and engaging pieces 40b provided near both ends in the left-right direction and facing the upper wall part 40a with a space in the prospective direction. In the state where the screen door 4 is attached, each engaging piece 40b is inserted into and engaged with two engaging holes 15d provided in the indoor upper frame 15, and the upper wall part 40a faces and is close to or in contact with the indoor protruding part 15c of the upper prospective surface part 15a in the prospective direction.
[0020] As shown in FIG. 4, at the lower end of the lower frame 41, there are a flat part 41a located on the indoor side, a concave part 41b provided adjacent to the flat part 41a on the outdoor side and recessed upward from the flat part 41a, and a guide piece 41c provided connected from the end on the outdoor side of the concave part 41b.
[0021] The lower frame 41 has a lower frame finding surface portion 41d that is connected to the indoor-side end of the flat surface portion 41a and has a finding surface facing the interior. The corner formed by the flat surface portion 41a and the lower frame finding surface portion 41d becomes the indoor-side corner (hereinafter referred to as the lower-end indoor corner) 41f of the screen door 4.
[0022] The recessed portion 41b is formed by a pair of groove wall portions 41g, 41h facing each other in the prospective direction, and a connecting portion 41i connecting the upper ends of the pair of groove wall portions 41g, 41h. The groove wall portion 41g that is the indoor-side end of the recessed portion 41b is connected to the flat surface portion 41a. The corner formed by the flat surface portion 41a and the indoor-side groove wall portion 41g becomes the outdoor-side corner (hereinafter referred to as the lower-end outdoor corner) 41j of the screen door 4.
[0023] The prospective-direction widths of the lower frame finding surface portion 41d and the indoor-side groove wall portion 41g are formed narrower than the interval between the outdoor-side end of the upper regulating portion 5b and the upper protruding piece 17b. The groove wall portion 41h that is the outdoor-side end of the recessed portion 41b has its lower end extended to the position of the flat surface portion 41a, and a guide piece 41c is provided at the tip of the outdoor-side groove wall portion 41h.
[0024] The guide piece 41c extends downward from the lower end of the outdoor-side groove wall portion 41h and is inclined so as to be positioned on the outdoor side downward. For this reason, the guide piece 41c extends below the flat surface portion 41a and is inclined in the direction away from the recessed portion 41b in the prospective direction.
[0025] And the interval W1 in the prospective direction between the lower end 41k of the guide piece 41c and the indoor-side groove wall portion 41g of the recessed portion 41b is configured to be narrower than the interval W2 in the prospective direction between the regulating member finding surface 5d and the lower finding surface portion 17d that is the indoor-side end of the protruding portion 17c.
[0026] As shown in FIGS. 6 and 7, the lower-end portion of the lower frame 41 is provided with the lower frame finding surface portion 41d, the flat surface portion 41a, and the indoor-side groove wall portion 41g over the entire width of the screen door 4 in the left-right direction. The connecting portion 41i and the outdoor-side groove wall portion 41h are not provided at both ends of the screen door 4 in the left-right direction, and the guide piece 41c is provided only at the left and right ends of the outdoor-side groove wall portion 41h.
[0027] More specifically, the lower frame finding surface portion 41d, the flat surface portion 41a, and the indoor side groove wall portion 41g are provided up to a position facing the regulating member 5 provided on the indoor lower frame 17 in the left - right direction in the prospective direction, and the left - right ends of the connecting portion 41i, the outdoor side groove wall portion 41h, and the guide piece 41c are located on the center side in the left - right direction rather than the position where the regulating member 5 is arranged.
[0028] The vertical frame 42 is connected to the upper wall portion 40a of the upper frame 40 and has a vertical wall portion 42a provided over substantially the entire length in the vertical direction. The vertical wall portion 42a faces the indoor vertical frame 19 in the prospective direction with the screen door 4 attached to the window frame 1.
[0029] The method of attaching the screen door 4 of the fitting 3 is attached in a kendon - style with the window frame 1 to which the shoji 2 is attached being in a mounted state. Specifically, first, as shown in Fig. 8(a), with the screen door 4 tilted such that the upper side is on the outdoor side, that is, on the shoji 2 side, from the lower side, the upper end of the screen door 4 is arranged below the upper prospective surface portion 15a of the indoor upper frame 15.
[0030] Next, as shown in Fig. 8(b), the screen door 4 is lifted obliquely upward, and the left and right engaging pieces 40b are inserted into the engaging holes 15d of the indoor upper frame 15. At this time, the upper wall portion 40a is located on the indoor side of the indoor protruding portion 15c of the indoor upper frame 15. Then, with the engaging pieces 40b inserted into the engaging holes 15d, the lower end side of the screen door 4 is moved to the outdoor side, and the screen door 4 is made to assume a posture along substantially the vertical direction, as shown in Fig. 8(c).
[0031] Next, as shown in Fig. 8(d), the screen door 4 is moved downward, the upward protruding piece 17b is inserted into the concave portion 41b, and the connecting portion 41i is placed on the upward protruding piece 17b, whereby the screen door 4 is attached. Here, the upward protruding piece 17b corresponds to a screen door mounting piece that protrudes upward from the lower prospective surface portion 17a of the lower frame 12 along the prospective direction and on which the screen door 4 is placed.
[0032] When the screen door 4 is lifted obliquely upward and then in a substantially vertical posture, the flat portion 41a of the lower frame 41 is located above the regulating member 5. When the screen door 4 is moved downward, if the lower inner corner portion 41f at the lower end of the screen door 4 is located between the upward protruding piece 17b and the upper regulating portion 5b of the regulating member 5, the upward protruding piece 17b enters the recess 41b of the screen door 4 and the screen door 4 is mounted.
[0033] Also, when the screen door 4 is moved downward, as shown in Fig. 9(a), when the lower inner corner portion 41f at the lower end of the screen door 4 contacts the outdoor inclined surface 5f of the regulating member 5, the downward movement of the screen door 4 is restricted by the outdoor inclined surface 5f. At this time, with the lower inner corner portion 41f in contact with the outdoor inclined surface 5f, the guide piece 41c is located above the upward protruding piece 17b. Then, the screen door 4 in which the lower inner corner portion 41f contacts the outdoor inclined surface 5f moves outward by the outdoor inclined surface 5f, and the lower end 41k of the guide piece 41c moves outward from the upward protruding piece 17b, so that the upward protruding piece 17b is accommodated in the recess 41b and the screen door 4 is mounted.
[0034] On the other hand, when the screen door 4 is moved downward, as shown in Fig. 10(a), when the lower outer corner portion 41j at the lower end of the screen door 4 abuts against the indoor inclined surface 5e of the regulating member 5, the lower end of the screen door 4 is guided by the indoor inclined surface 5e and moves inward along the indoor inclined surface 5e. Along with the movement of the lower end of the screen door 4, as shown in Fig. 10(b), the lower end 41k of the guide piece 41c moves inward from the protruding portion 17c, and the lower outer corner portion 41j moves inward from the indoor inclined surface 5e, and the screen door 4 is not supported by the window frame 1 and is not mounted while being held by the operator.
[0035] According to the fitting 3 of this embodiment, the screen door 4 has, at the lower end of the lower frame 41, a recess 41b into which the upward protruding piece 17b of the lower frame 12 is inserted, and a guide piece 41c that is connected to the recess 41b and extends to the outdoor side to guide the upward protruding piece 17b into the recess 41b. Therefore, when being mounted by the tipping method, when the upward protruding piece 17b located below the screen door 4 moves the screen door 4 downward in a state of being positioned between the indoor groove wall portion 41g of the recess 41b and the lower end 41k of the guide piece 41c in the expected direction, the upward protruding piece 17b is received in the recess 41b, and the screen door 4 is correctly mounted.
[0036] Further, when the screen door 4 mounted by the tipping method comes into contact with the indoor inclined surface 5e of the regulating member 5 when being moved downward, the screen door 4 is guided indoors from the regulating member contact surface 5d by the indoor inclined surface 5e. At this time, since the distance W1 in the expected direction between the indoor groove wall portion 41g of the recess 41b and the lower end 41k of the guide piece 41c is configured to be narrower than the distance W2 in the expected direction between the regulating member contact surface 5d of the regulating member 5 and the lower finding surface 17d which is the indoor side end of the overhanging portion 17c, the screen door 4 guided indoors from the regulating member contact surface 5d will not have the guide piece 41c placed on the overhanging portion 17c. For this reason, since the guide piece 41c is not mistakenly placed on the overhanging portion 17c, it becomes possible to more reliably mount the screen door 4 mounted by the tipping method.
[0037] Further, the regulating member 5 has an outdoor inclined surface 5f on the outdoor side of the indoor inclined surface 5e, the height of which decreases toward the outdoor side. When the lower end indoor corner portion 41f of the screen door 4 that has been moved downward when the screen door 4 is mounted by the tipping method comes into contact with the outdoor inclined surface 5f, the downward movement of the screen door 4 is restricted, and the lower end of the screen door 4 is guided to the outdoor side. At this time, since the guide piece 41c is located above the upward protruding piece 17b, when the screen door 4 with the lower end indoor corner portion 41f in contact with the outdoor inclined surface 5f moves to the outdoor side, the lower end 41k of the guide piece 41c moves to the outdoor side from above the upward protruding piece 17b. Then, since it is guided by the guide piece 41c and the upward protruding piece 17b is received in the recess 41b, it becomes possible to easily mount the screen door 4 in the correct position.
[0038] In addition, since the regulating member 5 and the guide piece 41c are provided at positions that do not face each other in the expected direction, when mounting in a swinging manner, it is not necessary to lift the guide piece 41c to a height where it does not contact the regulating member 5. For this reason, it is possible to reduce the amount of vertical movement of the screen door 4 when mounting it in a swinging manner, and it is possible to increase the size of the screen door 4, so it is possible to secure a larger opening area of the screen door 4.
[0039] The above-described embodiment is for facilitating the understanding of the present invention and is not for limiting and interpreting the present invention. It goes without saying that the present invention can be changed and improved without departing from its gist, and equivalents thereof are included in the present invention.
[0040] This embodiment includes at least the following inventions. Aspect 1: A fitting having a screen door mounted in a swinging manner on the indoor side of a window frame, the fitting having a regulating member attached to a lower frame constituting the window frame to regulate the mounting position of the screen door, the lower frame having a prospective surface portion along the prospective direction, a screen door mounting piece protruding upward from the prospective surface portion on which the screen door is placed, and a protruding portion protruding inward from the prospective surface portion on the indoor side of the screen door mounting piece, the regulating member having a regulating member finding surface disposed on the indoor side of the protruding portion and an indoor inclined surface connected above the regulating member finding surface and having an inclination decreasing in height toward the indoor side, the lower frame of the screen door having a recess provided at the lower end and recessed upward into which the screen door mounting piece is inserted, and a guide piece connected to the recess and extending outward to guide the screen door mounting piece into the recess, the distance in the prospective direction between the indoor-side end of the recess and the lower end of the guide piece being narrower than the distance in the prospective direction between the regulating member finding surface and the indoor-side end of the protruding portion.
[0041] According to the fitting of Mode 1, the screen door has, at the lower end of the lower frame, a recess into which the screen door placement piece of the downwardly recessed lower frame is inserted, and a guide piece that is connected to the recess and extends to the outdoor side to guide the screen door placement piece into the recess. Therefore, when the screen door is mounted in the tipping manner, the screen door placement piece located below the screen door is in a state of being positioned between the indoor-side end of the recess of the screen door and the lower end of the guide piece in the expected direction. When the screen door is moved downward, the screen door placement piece is received in the recess, and the screen door is correctly mounted. Further, when the screen door mounted in the tipping manner contacts the indoor inclined surface of the regulating member when moved downward, the screen door is guided indoors from the finding surface of the regulating member by the indoor inclined surface.
[0042] At this time, the distance between the indoor-side end of the recess and the lower end of the guide piece in the expected direction is configured to be narrower than the distance between the finding surface of the regulating member and the indoor-side end of the protruding portion in the expected direction. Therefore, the screen door guided indoors from the finding surface of the regulating member will not have the guide piece placed on the protruding portion. For this reason, the screen door is not arranged in an incorrect state where the guide piece is placed on the protruding portion, so it is possible to more reliably mount the screen door mounted in the tipping manner.
[0043] Mode 2: The fitting according to Mode 1, wherein the regulating member has an outdoor inclined surface that forms an inclination with a decreasing height toward the outdoor side on the outdoor side of the indoor inclined surface, and the screen door is characterized in that the lower end contacts the outdoor inclined surface and the guide piece is located above the screen door placement piece.
[0044] According to the fitting of Mode 2, the regulating member has an outdoor inclined surface with a decreasing height toward the outdoor side on the outdoor side of the indoor inclined surface. When the lower end of the screen door that has been moved downward when the screen door is mounted in the tipping manner contacts the outdoor inclined surface, the downward movement of the screen door is regulated, and the lower end of the screen door is guided to the outdoor side. At this time, since the guide piece is located above the screen door placement piece, when the screen door with the lower end contacting the outdoor inclined surface moves to the outdoor side, the guide piece moves to the outdoor side from the screen door placement piece. Then, guided by the guide piece, the screen door placement piece is received in the recess, so it is possible to easily mount the screen door in the correct position.
[0045] Aspect 3: The fitting according to Aspect 1 or Aspect 2, characterized in that the restricting member and the guiding piece are provided at positions not facing each other in the prospective direction.
[0046] According to the fitting of Aspect 3, since the restricting member and the guiding piece are provided at positions not facing each other in the prospective direction, when mounting in a slamming manner, it is not necessary to lift the guiding piece to a height where it does not contact the restricting member. For this reason, it is possible to reduce the amount of vertical movement of the screen door, and the size of the screen door can be increased, so that a larger opening area of the screen door can be ensured.
