  The upper frame 12 is provided with an upper cover plate 13 at a position on the outer surface of the side wall portion 12b. The upper cover plate 13 is a thin plate-like member having a dimension along the finding direction larger than that of the side wall portion 12b, and is arranged so as to be slidable in a direction perpendicular to the upper wall portion 12a with respect to the side wall portion 12b. The upper cover plate 13 can cover a gap generated between the upper cover plate 13 and the lintel E1 by appropriately sliding the upper frame 12 when the upper frame 12 is attached to the lintel E1. In addition, the code | symbol 23 in FIG. 3 is the cap arrange | positioned at the both ends of the space (henceforth guide space) enclosed by the upper wall part 12a, the side wall part 12b, and the middle wall part 12c. As can be seen from the figure, a portion of the cap 23 exposed to the outside from the end face of the upper frame 12 is provided with a relief portion 23a between the upper wall portion 12a.

  As shown in FIGS. 4 and 5, the vertical frame 11 has a prospective wall portion 11a and a pair of side wall portions 11b. The prospective wall portion 11 a is a part that is attached to the intermediate column (frame) E <b> 2 of the opening E and constitutes the prospective surface of the vertical frame 11. A pair of receiving grooves 11c are formed in the prospective wall portion 11a along the longitudinal direction. The accommodation groove 11c is a recess provided for disposing the door stopper 30 that serves as a cushion when the shoji 20 abuts, and is formed in the entire length of the portion of the vertical frame 11 that faces each shoji 20. It is.

  As shown in FIG. 4, in the present embodiment, the housing groove 11c has the first rib 11d facing inward at the opening edge and the second rib 11e having a larger protruding amount behind the first rib 11d. Is formed in the vertical frame 11, and the door stopper 30 is held by the first rib 11d and the second rib 11e. The door stopper 30 is a long member that is continuous upward from the lower end of the vertical frame 11, and is slightly lower than the lower surface of the side rail portion 12d provided on the upper frame 12, as shown in FIG. It ends at the position. As shown in FIG.4 and FIG.5, the side wall part 11b is extended toward the outer peripheral side from the both-sides edge part of the prospective wall part 11a. Side cover plates 14 are disposed on the side wall portions 11b at positions corresponding to the outer surfaces. The side cover plate 14 is a thin plate-like member having a dimension along the finding direction larger than that of the side wall portion 11b, and is arranged so as to be slidable in a direction perpendicular to the prospective wall portion 11a with respect to the side wall portion 11b. . The side cover plate 14 can cover a gap generated between the side cover plate 14 and the intermediate column E2 by appropriately sliding the vertical frame 11 when the vertical frame 11 is attached to the intermediate column E2.

  As shown in FIG. 3, elastic engagement members 40 are disposed in the portions where the accommodation grooves 11 c are formed in the upper end portion of the vertical frame 11. The elastic engagement member 40 is a metallic thin plate member having a width that can be accommodated in the accommodation groove 11 c, has a clip portion 42 at the upper end of the substrate portion 41, and a contact piece portion at the lower end of the substrate portion 41. 43. The clip portion 42 is a flat plate-like portion that extends downward from the upper end of the substrate portion 41 and then extends downward. The substrate portion 41 is inclined with respect to the clip portion 42 so as to gradually approach the clip portion 42 as it goes downward, and further, the lower end portion thereof extends so as to be substantially parallel to the clip portion 42. The contact piece portion 43 is a portion extending upward after being bent in a direction away from the clip portion 42 from the lower end of the substrate portion 41. The contact piece portion 43 is inclined so as to be gradually separated from the substrate portion 41 as it goes upward. The upper end of the contact piece 43 is set to a length located below the upper end of the substrate portion 41 when the clip portion 42 is disposed substantially vertically. The elastic engagement member 40 is held by the vertical frame 11 by inserting the upper end of the vertical frame 11 between the substrate portion 41 and the clip portion 42, and as shown in FIG. 3 and FIG. The upper end of the piece 43 protrudes from the prospective surface of the vertical frame 11 beyond the accommodation groove 11c.

  When assembling the opening frame 10 of the joinery configured as described above, as shown in FIG. 7A, the vertical frame 11 is first formed along each side edge with respect to the opening E of the partition wall W. Install. Specifically, as shown in FIG. 4, the vertical frame 11 is fixed to the intermediate column E2 by screwing screws B into the intermediate column E2 of the opening E through the accommodation groove 11c. At this time, if the elastic engagement member 40 is disposed in advance at the upper end of the vertical frame 11, the clip portion 42 of the elastic engagement member 40 is sandwiched between the upper end of the vertical frame 11 and the lintel E1. Thus, even when an external force is received from below, the elastic engagement member 40 does not fall off the vertical frame 11. When the vertical frame 11 is attached, the attachment work can be performed with the lower end of the vertical frame 11 placed on the floor surface. Therefore, it is easy to position the vertical frame 11 with one hand, and the construction can be performed by one person. Is possible.

  After the vertical frames 11 are attached to both side edges of the opening E, the upper frame 12 is disposed between the vertical frames 11 in a posture along the left-right direction, and the end surfaces of the upper frame 12 are respectively the prospective surfaces of the vertical frame 11. The upper frame 12 is moved upward in a state of being opposed to. When the upper frame 12 is moved upward, as shown in FIG. 8 (a), the upper wall portion 12a of the upper frame 12 eventually reaches the contact piece 43 of the elastic engagement member 40 protruding from the housing groove 11c. Abut. When the upper frame 12 is further moved upward from this state, the contact piece 43 is elastically deformed toward the inside of the receiving groove 11c, and as shown in FIG. The upper frame 12 can be moved upward beyond the upper end of the piece 43. When the upper frame 12 moves upward beyond the upper end of the contact piece 43, the contact piece 43 protrudes from the receiving groove 11c by the elastic restoring force and faces the lower surface of the upper wall 12a. . At this time, since the escape portions 23a are formed in the caps 23 disposed at both ends of the upper frame 12, there is no possibility of interference with the cap 23 when the contact piece 43 is elastically restored. 43 reliably protrudes to a position facing the lower surface of the upper wall portion 12a.

  In this state, when the upper frame 12 is moved downward, the lower surface of the upper wall portion 12a is the upper end of the contact piece portion 43 as shown in FIGS. 7B, 8B, and 9. Then, the upper frame 12 is locked to the vertical frame 11 without dropping even when the hand is released from the upper frame 12. Here, the elastic engagement member 40 receiving the load of the upper frame 12 is deformed. However, the contact piece portion 43 of the elastic engagement member 40 is inclined so as to be gradually separated from the substrate portion 41 as it goes upward. Therefore, the deformation of the elastic engagement member 40 due to the load of the upper frame 12 becomes a direction in which the contact piece 43 protrudes from the receiving groove 11c, and acts in a direction that reliably prevents the upper frame 12 from moving downward. .

  Thus, when the upper frame 12 is locked to the upper portion of the vertical frame 11 via the elastic engagement member 40, it is easy to position the upper frame 12 with respect to the lintel E1 with one hand. Become. Thereby, even if the width | variety of the opening frame 10 is large and the dimension along the longitudinal direction of the upper frame 12 is as large as 3000-4000 mm, it becomes possible to construct an assembly work alone. In addition, the elastic engagement member 40 for locking the upper frame 12 is such that only the upper end of the contact piece 43 protrudes from the prospective surface of the vertical frame 11, and the upper frame 12 is moved upward from below with respect to the vertical frame 11. When it is moved to the position, it is elastically deformed toward the inside of the receiving groove 11c. Accordingly, the end surface of the upper frame 12 can be moved upward while being in sliding contact with the prospective surface of the vertical frame 11, and the gap between the prospective surface of the vertical frame 11 and the end surface of the upper frame 12 is set as small as possible. In this state, the upper frame 12 can be attached so as to span between the upper end portions of the vertical frame 11. Further, after the upper frame 12 is attached to the lintel E1, the contact piece 43 of the elastic engagement member 40 is covered by the side wall portion 12b of the upper frame 12, and the appearance quality may be greatly impaired. Absent.

  In the above-described embodiment, the elastic engagement member 40 is disposed on each of the vertical frames 11 attached to both side edges of the opening E. However, in the present invention, only at least one vertical frame 11 is provided. The elastic engagement member 40 may be provided. For example, in the first modification shown in FIG. 10, the block member 50 is disposed in the accommodation groove 11 c of one vertical frame 11 so as to protrude from the prospective surface. The block member 50 is formed of, for example, a resin material, and is attached to the receiving groove 11c of the vertical frame 11 so that the position slightly separated from the lower surface of the lintel E1 is the upper surface. Although not shown in the drawing, in the accommodation groove 11c of the other vertical frame 11, an elastic engagement member 40 is disposed at the upper end of the accommodation groove 11c as in the first embodiment.

  Also in the first modification, the upper frame 12 is slightly tilted, and the upper wall portion 12a at one end is first inserted between the upper surface of the block member 50 and the lintel E1, and then the other end of the upper frame 12 is inserted. If the end portion is moved upward, the upper frame 12 can be locked to the upper portion of the vertical frame 11. Therefore, the upper frame 12 can be easily positioned with respect to the lintel E1 with one hand, and the assembly work can be performed even when the width of the opening frame 10 is large and the dimension along the longitudinal direction of the upper frame 12 is large. It will be possible to work alone. Further, as in the first embodiment, the elastic engagement member 40 is such that only the upper end of the abutting piece 43 protrudes from the prospective surface of the vertical frame 11 and the upper frame 12 is moved upward from below with respect to the vertical frame 11 In such a case, it is configured to elastically deform toward the inside of the accommodation groove 11c. Accordingly, the end surface of the upper frame 12 can be moved upward while being in sliding contact with the prospective surface of the vertical frame 11, and the gap between the prospective surface of the vertical frame 11 and the end surface of the upper frame 12 is set as small as possible. In this state, the upper frame 12 can be attached so as to span between the upper end portions of the vertical frame 11. As for the block member 50 disposed in the receiving groove 11c, the contact piece 43 of the elastic engagement member 40 is covered by the side wall portion 12b of the upper frame 12 after the upper frame 12 is attached to the lintel E1. Thus, the appearance quality is not greatly impaired.

  Further, in the above-described embodiment, the elastic engagement member 40 is provided with the clip portion 42, and the upper end of the vertical frame 11 is inserted between the substrate portion 41 and the clip portion 42 so that the elastic engagement member 40 is placed in the vertical frame. However, the present invention is not limited to this. For example, as in the second modification shown in FIG. 11, the elastic engagement member 140 may be attached to the accommodation groove 11 c of the vertical frame 11 with a screw 150. In this case, the elastic engagement member 140 does not need to have a clip portion. For example, the elastic contact member 140 is inclined so as to be gradually separated from the substrate portion 141 as it goes upward from the upper end of the substrate portion 141. What has the contact piece part 143 should just be applied.

  As a portion to which the screw 150 for attaching the elastic engagement member 140 is screwed, a screw hole may be directly formed in the vertical frame 11, but a bracket plate 151 having a large plate thickness is separately prepared. A screw hole 151 a may be formed in the plate 151. As the bracket plate 151, one having a width wider than the mutual interval of the second ribs 11e is applied, and if this is arranged at the back of the second rib 11e, the screws 150 are screwed together, The elastic engagement member 140 is attached to the receiving groove 11c with the second rib 11e sandwiched between the elastic engagement member 140 and the elastic engagement member 140.

  In the above-described embodiment, the first modification, and the second modification, the assembly structure of the opening frame is described in which the shoji is supported by being hung on the upper frame via the door wheel. It is not restricted to what is supported in the state suspended from the upper frame. Further, although the opening frame not provided with the lower frame is illustrated, it is of course applicable to the case of assembling the opening frame provided with the lower frame.
