It is related with the fitting which supported the upper end part of the shoji so that it could slide with respect to a frame by making it slide-contact with.

  In fittings such as sliding windows and single-sided windows where the shoji is slidable with respect to the frame, a guide fin is usually provided on the upper frame member of the frame, and a guide groove is formed at the upper end of the shoji. Is provided. The guide fin portion is a plate-like portion protruding downward from the prospective surface of the upper frame member, and is provided along the longitudinal direction of the upper frame member. The guide groove is formed in a portion facing the guide fin portion on the upper surface of the upper collar member. The guide groove has a width larger than the thickness of the guide fin portion, and the guide rod located at the other end portion through the upper flange member from the upper end portion of the longitudinal member located at one end portion of the shoji.

Japanese Patent Laid-Open No. 2005-200932 JP 2007-255079 A

  By the way, in the joinery described above, the space between the upper frame member and the shoji is only supported by the guide fin portion and the sliding piece. For this reason, when a large wind load is applied to the shoji, this wind load is transmitted to the guide fin portion only through the sliding pieces at both ends in the longitudinal direction. Therefore, when a large wind load is received, the guide fin portion is damaged due to stress applied intensively through the sliding piece, which may greatly affect the sliding operability of the shoji. In recent years, buildings tend to be super-high, and the wind load applied to the joinery increases as the building becomes taller, so that the above-described problem becomes more prominent.

  Such a problem can be considered to increase the contact area with the guide fin portion, for example, by disposing the sliding piece also on the upper flange member. However, when a large number of sliding pieces are provided, the sliding resistance when sliding the shoji is increased according to the number of sliding pieces, there is a possibility that the sliding operability of the shoji is impaired.

  An object of this invention is to provide the fitting which can endure a big wind load, without impairing the sliding operativity of a shoji in view of the said situation.

  In order to achieve the above object, the joinery according to the present invention has sliding pieces, each having a sliding groove between a pair of sliding surfaces, arranged at both ends in the longitudinal direction of the guide groove provided at the upper end of the shoji. The upper end portion of the shoji is moved with respect to the frame body by slidingly contacting the sliding surface of the sliding piece with the guide fin portion provided on the upper frame member of the frame body being accommodated in the guide groove. The sliding door guide groove has a guide surface at each of the portions located on the outdoor side and the indoor side, and either one of the guide surfaces has the above-mentioned guide groove. While the distance between the guide fin portion and the guide fin portion is greater than the slide surface of the slide piece, the distance between the guide fin portion and the guide fin portion is greater than the slide surface of the slide piece. It is characterized by providing a support surface at a position smaller than the distance between .

  According to the present invention, when the shoji is subjected to a large wind load, the support surface provided between the sliding pieces comes into contact with the guide fin portion, so that it is possible to prevent a situation where the wind load is intensively applied to the guide fin portion. This eliminates the possibility of causing damage such as deformation to the guide fin portion.

  In the joinery described above, the present invention is characterized in that the support surface is provided over the entire length of the portion located between the sliding pieces on the one guide surface.

  According to the present invention, even when various sizes of shojis are configured, it is necessary to separately calculate the stress generated in the saddle member due to the wind load and prepare a necessary number of reinforcing parts. However, the wind load can be easily and reliably distributed to the guide fin portion.

  In the joinery described above, the present invention is characterized in that the support surface is configured by attaching a support member between the one guide surface and the guide fin portion.

  According to this invention, the shoji installed in a place with a large wind load and the shoji installed in a place with a small wind load can be shared depending on whether or not the support member is attached.

  In the joinery described above, the present invention is characterized in that a plurality of support protrusions are provided on a portion of the support surface facing the guide fin portion.

  According to the present invention, the contact area when the shoji comes into contact with the support surface when sliding the shoji can be reduced, and there is no possibility of affecting the slide operability.

  Moreover, the present invention is the above-mentioned joinery, wherein the shoji is provided with the upper eaves member between upper ends of a pair of eaves members, and the sliding piece is attached to each eaves member, The support surface is provided at a portion extending over the entire length of the upper collar member.

  According to the present invention, even when various sizes of shojis are configured, it is necessary to separately calculate the stress generated in the saddle member due to the wind load and prepare a necessary number of reinforcing parts. However, the wind load can be easily and reliably distributed to the guide fin portion.

  According to the present invention, when the shoji is subjected to a large wind load, the support surface provided between the sliding pieces abuts against the guide fin portion, thereby preventing a situation where the wind load is concentrated on the guide fin portion. can do. Therefore, there is no possibility of causing damage such as deformation to the guide fin portion, and it is possible to maintain good operability when sliding the shoji.

FIG. 4 is an enlarged vertical cross-sectional view of a main part showing a modification of the joinery shown in FIG.

  Hereinafter, preferred embodiments of a fitting according to the present invention will be described in detail with reference to the accompanying drawings. 2 and 3 show a joinery that is an embodiment of the present invention. The joinery illustrated here is a sliding window that includes two shojis 20 inside the frame 10 and that opens and closes the opening of the frame 10 by sliding the shojis 20 to the left and right.

  The frame 10 is configured by rectangularly forming an upper frame member 11, a lower frame member 12, and a pair of vertical frame members 13 by making a four-round frame. Each of the frame members 11, 12, 13 constituting the frame body 10 is an extruded shape member formed of aluminum or an aluminum alloy, and each has a substantially uniform cross-sectional shape over the entire length. As shown in FIG. 1, the upper frame member 11 of the frame 10 is provided with a pair of cover fin portions 11a and a pair of guide fin portions 11b on the prospective surface. The cover fin portion 11 a has a plate shape protruding downward from both side portions of the upper frame member 11, and is provided over the entire length along the longitudinal direction of the upper frame member 11. The guide fin portion 11b has a plate-like shape that protrudes downward from two portions of the prospective surface of the upper frame member 11 that are located on the outdoor side and the portion located on the indoor side. The entire length is provided along the direction. As is apparent from the figure, the guide fin portion 11b is configured to protrude slightly below the cover fin portion 11a and to have a larger plate thickness than the cover fin portion 11a.

  As shown in FIG. 2, the shoji 20 is configured by providing an upper collar member 22, a lower collar member 23, and a pair of vertical collar members 24 on the four circumferences of a rectangular face material 21. In the shoji 20 according to the present embodiment, the upper collar member 22 is disposed between the upper end portions of the vertical collar member 24. The saddle members 22, 23, and 24 constituting the shoji 20 are extruded shapes formed of aluminum or aluminum alloy, like the frame members 11, 12, and 13, and each has a substantially uniform cross-sectional shape over the entire length. ing. As shown in FIGS. 1 and 3, a guide groove 26 is provided at the upper end portion of each shoji 20, and a sliding piece 30 is attached to a portion that is at both ends of the guide groove 26.

  The guide groove 26 is a space formed in a portion extending from the upper surface of the upper collar member 22 to the upper surface of the vertical collar member 24. In the present embodiment, by projecting the groove fin portions 22b upward from the both side portions of the base portion 22a facing the end surface of the face member 21 in the upper collar member 22, the groove fin portions 22b are interposed between each other. A guide groove 26 of the upper collar member 22 is configured. More specifically, the groove fin portion 22b has a flat plate shape, and has rib portions 22c, 22d, and 22e at three locations facing each other. The rib portion provided at the upper end of the groove fin portion 22b (hereinafter referred to as “first rib portion 22c” for distinction) protrudes toward the opposite groove fin portion 22b, and then the protruding end portion extends downward. It is configured to be bent by approximately 90 ° toward it. After the rib portion provided below the first rib portion 22c in the groove fin portion 22b (hereinafter referred to as “second rib portion 22d” when distinguished) protrudes toward the opposite groove fin portion 22b, The protruding end portion is configured to be bent approximately 90 ° upward. A rib portion provided below the second rib portion 22d in the groove fin portion 22b (hereinafter referred to as “third rib portion 22e” when distinguished) is opposed from a position close to the base portion 22a of the upper collar member 22. It protrudes toward the groove fin portion 22b. As is apparent from FIG. 1, these rib portions 22c, 22d, and 22e are provided so that the projecting dimensions from the groove fin portions 22b are equal to each other, and virtual guides are provided at positions that connect the respective projecting ends. A surface 22f (a plane indicated by a two-dot chain line in FIG. 1) is formed, and a guide groove 26 is formed between the guide surfaces 22f.

  As shown in FIG. 3, the guide groove 26 of the vertical hook member 24 is configured by cutting away a portion corresponding to the guide groove 26 of the upper hook member 22 at each upper end portion. As shown in FIGS. 1 and 3, the guide groove 26 formed in the upper flange member 22 and the vertical flange member 24 has a width larger than the plate thickness of the guide fin portion 11 b provided in the upper frame member 11. The guide fin portion 11b can be accommodated.

  The sliding piece 30 is a block-like member attached to the vertical rod member 24 located at both ends of the guide groove 26, and is formed of a resin material that can slide smoothly with respect to the guide fin portion 11b. Each sliding piece 30 is provided with a sliding groove 31 in a portion corresponding to the guide groove 26 of the upper collar member 22. The sliding groove 31 is a narrow space formed between the pair of sliding surfaces 32, and is formed to have a width that can slidably accommodate the guide fin portion 11b.

  Further, as shown in FIG. 1, the upper collar member 22 of the shoji 20 is positioned so as to cover a guide surface (hereinafter referred to as “outer guide surface 22 fo” when distinguished) configured on the outdoor side of the guide groove 26. A support member 40 is provided. The support member 40 is an extruded shape member formed of aluminum or an aluminum alloy like the upper collar member 22, and has a uniform cross-sectional shape over the entire length. In the present embodiment, the support member 40 includes the prospective wall portion 41, the finding wall portion 42, the support wall portion 43, and the engagement wall portion 44.

  The prospective wall portion 41 is a flat plate portion disposed between the base portion 22a and the third rib portion 22e in a state along the base portion 22a of the upper collar member 22. The prospective wall portion 41 is configured to have a width that is larger than the distance between the guide grooves 26 and smaller than the distance from one guide surface 22f to the opposing groove fin portion 22b. The finding wall portion 42 is a flat plate-like portion that protrudes at a right angle upward from an edge portion located on the outdoor side of the prospective wall portion 41. The protruding dimension of the finding wall portion 42 from the prospective wall portion 41 is configured to be smaller than the distance from the base portion 22a of the upper collar member 22 to the second rib portion 22d. The support wall 43 is a flat plate portion that extends from the protruding end of the find wall 42 so as to be continuous with the find wall 42. As is clear from FIG. 1, the support wall portion 43 is configured to be offset toward the indoor side with respect to the finding wall portion 42. The offset amount of the support wall portion 43 is such that the distance from the surface facing the outdoor side of the finding wall portion 42 to the plane facing the indoor side of the support wall portion 43 (hereinafter referred to as “support surface 43a”) is from the outer guide surface 22fo. The sliding piece 30 is configured to be smaller than the distance to the sliding surface 32 located on the outdoor side. The engaging wall portion 44 protrudes in a direction perpendicular to the surface facing the outdoor side of the support wall portion 43 and then bends so as to become a right angle upward. The distance from the engagement wall portion 44 to the prospective wall portion 41 is smaller than the distance from the base portion 22a to the first rib portion 22c in the upper collar member 22, and larger than the distance from the base portion 22a to the second rib portion 22d. It is constituted as follows.

  The support member 40 configured as described above can be attached to the upper collar member 22 without dropping from the shoji 20 by inserting it from the end face of the upper collar member 22 in advance when assembling the shoji 20. That is, the prospective wall portion 41 is inserted between the base portion 22a of the upper collar member 22 and the third rib portion 22e, and the engagement wall portion 44 is inserted between the first rib portion 22c and the second rib portion 22d. Then, while the relative movement along the longitudinal direction of the support member 40 with respect to the upper collar member 22 is allowed, the movement along the finding direction and the prospective direction is restricted, so that the upper collar member 22 falls off. It is possible to mount the support member 40 without any problem. After the vertical hook members 24 are attached to both ends of the upper hook member 22, if the sliding pieces 30 are respectively attached to the upper end portions of the vertical hook members 24, the upper hook members 22 are brought into contact with the sliding pieces 30. The relative movement along the longitudinal direction of the support member 40 with respect to the member 22 is also restricted.

  As shown by the cross hatching in FIG. 2, the shoji 20 having the support member 40 attached to the upper collar member 22 has a sliding piece 30 attached to the upper end portion of the vertical collar member 24 on the outer guide surface 22fo of the upper collar member 22. The support wall portion 43 of the support member 40 is positioned over the entire length of the portion between the two. As shown in FIG. 1, the support surface 43 a of the support wall portion 43 is disposed at a position farther from the guide fin portion 11 b than the slide surface 32 positioned on the outdoor side of the slide piece 30. Therefore, if the shoji 20 is built in the frame 10 in this state, a gap is secured between the support surface 43a of the support wall 43 and the guide fin portion 11b of the upper frame member 11, and a large operating force is obtained. The shoji 20 can be slid without any need.

  Moreover, the distance between the support surface 43a and the guide fin portion 11b is between the guide surface (hereinafter referred to as “inner guide surface 22fi” when distinguished) and the guide fin portion 11b. It becomes a small state compared with the distance. Therefore, for example, even if a large wind load is applied to the shoji 20 by installing the joinery on the high floor of the skyscraper, the upper support member 22 slightly bends indoors to support the support surface 43a of the support member 40. Since it contacts the guide fin portion 11b, it is possible to prevent a situation in which wind loads are intensively applied to the guide fin portion 11b. Thereby, according to the said fitting, there is no possibility of causing damages such as deformation to the guide fin portion 11b, and the operability when sliding the shoji 20 can always be maintained well.

  In the above-described embodiment, since the support surface 43a is provided in the portion of the guide groove 26 that extends over the entire length between the sliding pieces 30, it is also generated in the eaves member by wind load even for fittings having different sizes. It is possible to always obtain the above-described effects without performing a complicated operation of separately calculating the stress and preparing the necessary number of reinforcing parts. However, in the present invention, the support surface 43a is not necessarily provided over the entire length, and for example, a plurality of support surfaces 43a may be provided at equal intervals.

  In the above-described embodiment, the support surface 43a is configured by mounting the support member 40, which is a separate body from the upper collar member 22, and therefore can be applied to existing joinery. In addition, by appropriately attaching and detaching the support member 40, the upper eaves member 22 can be shared with a joinery that is not likely to receive a large wind load, such as a joinery installed on a lower floor. . However, in the present invention, it goes without saying that a support surface may be provided integrally with the upper collar member.

  Further, in the above-described embodiment, the support surface 43a is illustrated as being flat, but the present invention is not necessarily limited to this. For example, as in the modification shown in FIG. The support surface 143a may be configured by providing a plurality of support protrusions 145 on the support wall portion 143 of the support member 140 having the 141, the finding wall portion 142, the support wall portion 143, and the engagement wall portion 144. In the case where a plurality of support protrusions 145 are provided, it is preferable that the protruding ends of the individual support protrusions 145 be positioned on the same plane parallel to the guide fin portion 11b. Even in a fitting in which the support surface 143a is configured by providing a plurality of support protrusions 145 on the support member 140, when a large wind load acts on the shoji 20, the upper collar member 22 slightly bends indoors. Thus, since the support surface 143a of the support member 140 contacts the guide fin portion 11b, it is possible to prevent a situation in which wind loads are intensively applied to the guide fin portion 11b. Thereby, according to the said fitting, there is no possibility of causing damages such as deformation to the guide fin portion 11b, and the operability when sliding the shoji 20 can always be maintained well. Moreover, even when the sliding screen 20 is slid, if the support protrusion 145 comes into contact with the guide fin portion 11b, the contact area with the guide fin portion 11b is smaller than that of the flat support surface. There is no risk of significant impact on In the modification shown in FIG. 4, the same reference numerals are given to the same components as those in the embodiment, and the detailed description is omitted.

  Furthermore, in the above-described embodiments and modifications, the support surface is provided only on the guide surface located on the outdoor side, but the present invention is not limited to this. For example, in a situation where negative pressure is applied, the support surface may be provided only on the guide surface located on the indoor side.
