Description

The present invention relates to a fitting that limits movement of a shoji with respect to a frame by engaging a lock operation member provided on the frame with an engagement member provided on the shoji.

For fittings where the shoji moves along the length of the frame material that makes up the frame, such as lift-down windows and double-sliding windows, the opening and closing movement of the shoji is restricted by operating the lock operation member provided on the frame. There is something I tried to do. For example, in a lift-down window in which the shoji moves up and down along the length of the vertical frame with respect to the frame, a lock operation member is provided on the vertical frame, and a lock operation member is provided at a position corresponding to the lock operation member on the vertical stile of the shoji. The engagement member is provided to protrude, and by engaging the lock operation member with the engagement member, it is possible to restrict vertical movement of the shoji with respect to the frame (for example, , see Patent Document 1).

By the way, the prospective surface of the vertical stile, which serves as a guide when moving the shoji relative to the frame, is always covered by the vertical frame. Therefore, it is not possible to screw the screw member into the vertical stile of the shoji screen built into the frame, and it is also difficult to attach the engaging member. For this reason, it is necessary to attach the engaging member to the prospective surface before installing the shoji in the frame, which causes problems such as the subsequent work of erecting the shoji into the frame becomes complicated. There is a risk of In addition, the above-mentioned problem also applies to fittings in which the shoji moves left and right relative to the frame, as well, between the prospective surface of the horizontal stile that serves as a guide when moving the shoji relative to the frame, and the horizontal frame. can occur.

In view of the above-mentioned circumstances, the present invention provides a fitting in which an engaging member can be attached to a projected surface that serves as a guide when moving a shoji, without complicating the work of erecting the shoji into a frame. With the goal.

In order to achieve the above object, the fittings according to the present invention are provided such that a shoji is movably arranged along the length of the guide frame with respect to a frame constructed by assembling guide frame materials and end frame materials four times. The fitting is configured to limit movement of the shoji with respect to the guide frame by engaging a lock operation member provided on the guide frame with an engagement member provided on the shoji, the fitting comprising: The engaging member and the prospective surface of the shoji that opposes the guide frame material are engaged with each other by moving along the extending direction of the prospective surface, and the tip end of the engaging member An engaging portion is provided to prevent movement in a direction away from the prospective surface, and the engaging member is fixed by screwing a screw member to the prospective surface facing the end frame member of the shoji. It is characterized by being provided with a fixing part that is fixed.

According to the present invention, the engaging part is engaged by inserting the engaging member from the end of the shoji along the extending direction of the prospective surface facing the guide frame material, and then the end frame member is engaged with the shoji. By screwing the screw member into the prospective surface facing the shoji, the fixed portion is fixed to the shoji, and relative movement of the engaging member with respect to the shoji is prevented. Thereby, even after the shoji is built into the frame, the engagement member can be provided on the prospective surface of the shoji that faces the guide frame material. Therefore, there is no need to erect the shoji with the engaging members attached, and the work can be prevented from becoming complicated.

There is.

Hereinafter, the attachment structure of the engaging member 42 to the inner shoji 20A will be explained in detail, and the characteristic parts of the present invention will also be explained. First, as shown in FIG. 8, when attaching the engaging member 42 to the inner sash 20A, before installing the inner sash 20A on the door frame 10, first, attach the engaging member 42 to the outer periphery of the vertical stile 24A facing the door vertical frame 13. The mounting plate 43 is attached to the prospective surface in advance. The mounting plate 43 is made by attaching the mounting board portion 43a to the outer peripheral side of the metal stile portion 25M of the vertical stile 24A before assembling the upper stile 22A, lower stile 23A, and vertical stile 24A four times around the inner sash 20A. If the screw member 44 is screwed into the screw hole 43b of the mounting board part 43a from the inner peripheral side of the metal frame part 25M through the screw insertion hole 25Ma, it becomes possible to attach it to the vertical stile 24A.

After attaching the mounting plate 43 to the vertical stile 24A, an upper stile 22A, a lower stile 23A, and a vertical stile 24A are attached to the four circumferences of the double-glazed glass 21A, and the inner stile 20A is constructed by connecting them to each other. do. Even when the upper stile 22A, lower stile 23A, and vertical stile 24A are assembled four times, if the sliding piece 27 is left in the state before the sliding piece 27 is attached, the inner sash 20A can be moved to the left and right sides of the door frame 10 as shown in FIG. It can be easily built into the

Here, when the inner sash 20A is built into the door frame 10, the outer circumferential surfaces of the left and right vertical frames 24A are covered by the door vertical frames 13 and 14, respectively. However, the upper surface of the upper stile 22A and the lower surface of the lower stile 23A can be exposed by appropriately moving the inner sash 20A up and down with respect to the door frame 10. Therefore, as shown in FIG. 8, the engaging member 42 is inserted into the gap between the vertical frame inner circumferential cover member 13C of the door vertical frame 13 and the vertical stile 24A from the upper side of the inner sash 20A, and the insertion piece 42c is inserted into the vertical frame 24A. By moving it along the extending direction of 24A, it is possible to perform the work of inserting it into the insertion hole 43e of the mounting plate 43. At this time, if the inner sash 20A is moved inside the door frame 10 toward the door vertical frame 14 on the opposite side, the gap between the vertical frame inner circumferential cover member 13C and the vertical frame 24A can be expanded, The above-mentioned work can be facilitated. Furthermore, as shown in FIG. 9(a), if the engagement member 42 is tilted so that the upper end is separated from the vertical stile 24A, the positioning protrusion 43c and the engagement base plate 42a will not come into contact with each other. The operation of inserting the insertion piece 42c into the insertion hole 43e can be easily performed.

After the insertion piece 42c is inserted into the insertion hole 43e, as shown in FIG. 9(b), if the upper end of the engagement plate portion 42d is brought close to the vertical stile 24A, the positioning protrusion 43c aligns with the positioning notch 42e. At the same time, the fixing plate portion 42b comes into contact with the upper surface of the upper stile 22A. Therefore, as shown in FIGS. 9 and 10, if the screw member 27a is screwed into the screw hole 22Aa of the upper stile 22A through the screw insertion hole 42f of the sliding piece 27 and the fixed plate part 42b, the sliding piece 27 At the same time, the engagement member 42 can be fixed to the inner sash 20A with the engagement plate portion 42d protruding from the guide groove 26 of the vertical stile 24A. In this state, the positioning protrusion 43c is inserted into the positioning notch 42e, thereby preventing the engagement member 42 from moving relative to the vertical stile 24A in the expected direction, and the insertion piece 42c is inserted into the insertion hole 43e. This prevents the engagement member 42 from moving relative to the stile 24A along the perspective direction and from moving away from the perspective surface of the stile 24A. Furthermore, when the positioning protrusion 43c is inserted into the positioning notch 42e, the attachment position of the engaging member 42 to the vertical stile 24A is accurately defined. Thereby, for example, if the fitting part 41b of the lock operation member 41 is inserted into the engagement hole 42h with the inner shovel 20A closed with respect to the door frame 10, the inner shovel 20A can be inserted through the engagement member 42. will be prevented from moving upward.

It is also possible to prevent movement along the top and bottom. Furthermore, when the inner shoji 20A and the outer shoji 20B are moved downward from the fully open state, the fitting portion 41b comes into contact with the guide inclined portion 42g provided on the engagement member 42, and the guide inclined portion 42g is inclined. Due to this action, the fitting portion 41b moves toward the indoor side against the spring force of the return spring. Thereafter, when the inner shoji 20A moves until the position of the engagement hole 42h coincides with the engagement part 41b, the engagement part 41b penetrates into the engagement hole 42h due to the spring force of the return spring. Therefore, if the inner shoji 20A is closed without operating the lock operation member 41, it is possible to prevent the inner shoji 20A from moving thereafter.

Note that the sliding pieces 28 may be attached to the inner shoji 20A and the outer shoji 20B at an appropriate timing, for example, after the engagement member 42 is attached to the inner shoji 20A. In this case, similarly to the sliding piece 27, screw members are screwed together from above the upper stile 22B and from below the lower stile 23B, so that it can slide against the outer shoji 20B built into the door frame 10. The moving piece 28 can be easily attached. After the sliding pieces 27 and 28 are attached, the gap between the door vertical frames 13 and 14 and the vertical door facing wall portions 13A2a and 14A2a is reduced. Therefore, movement of the ventilation shoji 20A, 20B along the left and right sides with respect to the door frame 10 is restricted. Therefore, even when the vertical stile 24A, 24B of one of the ventilation shoji 20A, 20B is moved so as to be close to the vertical frame 13, 14 of one door, the vertical stile 24A, 24B of the other door There is no fear that the ventilation shoji 20A, 20B will remain covered by the vertical frames 13, 14 and accidentally fall off from the door frame 10.

In this way, according to the above-mentioned fittings, the insertion piece 42c is inserted into the insertion hole 43e by inserting the engagement member 42 from the end of the inner sash 20A along the extending direction of the vertical stile 24A, and then, By screwing the screw member 27a onto the upper surface of the inner shoji 20A, the fixing plate portion 42b is fixed to the inner shoji 20A, and relative movement of the engagement member 42 with respect to the inner shoji 20A is prevented. Thereby, even after the inner sash 20A is built into the door frame 10, it is possible to provide the engagement member 42 on the vertical stile 24A of the inner sash 20A. Therefore, there is no need to erect the inner shoji 20A with the engaging member 42 attached, and the work can be prevented from becoming complicated.
