Description

The present invention relates to an upper frame installed in a retractable door, a retractable door structure using the upper frame, and a construction method thereof.

When installing a sliding door in an opening formed in a wall that partitions two adjacent rooms or spaces so that the opening can be opened and closed, the door is stored in one wall adjacent to the opening when the door is opened. A so-called pull-in door provided with a space (door pocket) for this purpose is performed (Patent Document 1). According to this sliding door structure, when the door is opened, the door cannot be seen from either side of two adjacent rooms or spaces, so that a clean and open impression can be given.

The construction of such a retractable door has conventionally been performed by attaching an upper frame to the upper surface of the opening, as well as an opening-side vertical frame, a door-seat-side door-contacting member (vertical material), a duck (or duck rail), and a sill (or sill rail). After fixing the door pocket, etc., fix the gypsum board on the door pocket, hang the sliding door on the Kamoi (or Kamoi rail), attach the stand on the opening edge of the door pocket, and finally put a cloth on the plaster board. It is carried out. When a cloth is pasted on a gypsum board, it is necessary to apply a caulking agent to a joint between a member (such as an upper frame) attached to the opening and the cloth. Although it is possible to attach a caulking agent by attaching a member such as an upper frame to the opening after pasting the cloth, the caulking agent is applied by an interior contractor as part of the cloth pasting process. Yes, it is inefficient to perform the work of applying the cloth and applying the caulking agent separately. Therefore, as described above, the operation of pasting the cloth and applying the caulking agent is performed as the final finishing operation after all necessary members such as the upper frame are attached to the openings.

However, since the upper frame as a joinery member is generally decorated with a decorative sheet or the like, if the cloth is pasted after attaching it to the upper surface of the opening, the makeup of the upper frame peels off or the upper frame is damaged In some cases, repair work or replacement work is required. The upper frame is fixed to the upper surface of the opening with screws or adhesive. To repair or replace the upper frame, remove the fixed upper frame, and then install the repaired upper frame or a new upper frame. It was necessary and required a lot of work. In addition, in order to prevent scratches, the upper frame is covered with a curing sheet, but this work takes extra time. Also, when it becomes necessary to repair or replace the sliding door, the fixed upper frame must be removed and then attached again, which requires a lot of work.

Therefore, the problem to be solved by the present invention is that even when the retractable doors are constructed in the above-mentioned construction order, the makeup of the upper frame is not impaired when the cloth is pasted, and the upper frame and the sliding door are repaired or replaced. It is an object of the present invention to provide a novel upper frame structure that allows easy removal and attachment of the upper frame.

In order to solve this problem, the present invention according to claim 1 is an upper frame that is attached to the upper surface of the opening portion of the retractable door, and the upper frame that is attached to the upper surface of the opening portion on the door pocket side of the retractable door is not subjected to makeup. An opening-side upper frame with a makeup attached to the upper surface of the opening on the door-end side, a door-bag-side mooring rail fitted and fixed to the mooring rail mounting recess on the lower surface of the door-side upper frame, and an opening-side upper frame The door-side rails fitted and fixed to the head-side rail mounting recesses on the lower surface of the door, and when the door frame side upper frame and the opening side upper frame are connected to form a linearly continuous upper frame, these door pockets A vertical storage recess for storing verticals on both sides in the width direction is formed between the side upper frame and the opening side upper frame.

According to a second aspect of the present invention, in the upper frame according to the first aspect, when the doorcase side upper frame and the opening side upper frame are connected to each other, the doorcase side head rail and the opening side head rail are connected. These seams are all located within the range of the vertical accommodating recess.

According to a third aspect of the present invention, in the upper frame according to the first or second aspect, the seam when the doorcase-side upper frame and the opening-side upper frame are connected to each other, and the door-bag-side heading rail and the opening-side heading rail are connected. In this case, the seam is in a substantially coincident position.

The present invention according to claim 4 is a retractable door structure having the upper frame according to any one of claims 1 to 3, wherein the doorcase-side upper frame and the opening-side upper frame are connected to form a straight line. In the upper frame formed as a continuous frame, the vertical frame is stored in the vertical storage recesses formed on both sides in the width direction between the door-side upper frame and the opening-side upper frame.

The present invention according to claim 5 is a construction method of the retractable door structure having the upper frame according to any one of claims 1 to 3, wherein the top of the door on the side of the door is not decorated. After attaching the frame, fitting and fixing the doorcase side rail to the bottom rail mounting recess on the bottom side of this doorcase side frame, pasting wall material and cloth on the bottom of the doorcase, applying makeup to the top of the door opening The upper frame that is opened is connected and connected to the door frame side upper frame to form a linearly continuous upper frame, and the open side rail is fitted and fixed to the lower rail mounting recess on the lower surface of the upper frame. And it is characterized by forming the Kamoi rail which continues linearly by connecting with the door pocket side Kamoi rail.

According to the present invention, the upper frame installed on the upper surface of the opening portion of the retractable door structure is divided into the door pocket side upper frame and the opening side upper frame, and the door rail on the door pocket side which is attached to the door pocket side upper frame and the opening. Since it is divided into the opening-side Kamoi rail attached to the side upper frame, attach the opening-side upper frame and the opening-side Kamoi rail after attaching the door pocket-side upper frame and the door-bag side Kamoi rail and performing the cross-pasting work. Can do. Therefore, there is no possibility of makeup peeling or damage due to the opening-side upper frame being damaged during the cloth pasting operation. Although the doorcase side upper frame is already attached at the time of the cross-pasting operation, no makeup is applied to the doorcase side upper frame, so there is no need to cover with a curing sheet to prevent damage.

In addition, if the opening-side upper frame or opening-side duck rail is damaged after repair, the opening-side upper frame or opening-side duck rail can be removed without breaking the door pocket. Repair and replacement work can be performed, and the labor and time are reduced.

Also, when the upper frame on the doorcase side and the upper frame on the opening side are connected to form a linearly continuous upper frame, the vertical frame is accommodated on both sides in the width direction between the upper frame on the doorcase side and the upper frame on the opening side. Since the vertical housing recess is formed, the vertical frame can be accommodated in the vertical housing recess and vertically attached to the upper frame, so that the upper frame and the duck rail located in the range of the vertical storage recess The seam can be concealed on the side face.

Also, the seam when the doorcase side upper frame and the opening side upper frame are connected, and the seam when the doorcase side heading rail and the opening side heading rail are connected, are both located within the range of the vertical accommodation recess. By comprising so, these seams are concealed by the vertical installed so as to be accommodated in the vertical accommodating recess, and are not visible from the outside (front side) of the door pocket, and the appearance is not impaired. Moreover, if these seams are configured so as to be substantially flush with the front face of the vertical frame, the work of attaching the opening-side upper frame continuously to the door-seat-side upper frame, and the opening-side heading rail to the door-siding side heading The operation | work which attaches to a rail continuously or the operation | work which removes them can be performed easily.

Further, by configuring the joints so as to be positioned substantially coincident with each other, when it is necessary to remove the once installed opening-side upper frame, it can be easily removed together with the opening-side head rail. If these seams do not match, the Kamoi rail protrudes from the upper frame on the opening side or the upper frame on the door pocket side, so when removing the upper frame on the opening side, there is a risk of catching and damaging the protruding part. Work efficiency is reduced, and work efficiency is reduced.

As described above, the connecting groove 262 is formed at a position that coincides with the connecting groove 256 of the lower local 25 when the makeup stand 26 is combined with the lower local 25.

In this embodiment, the decorative stand 26 has a length of 2469 mm, a width (a distance between the outer surface 263c and the inner surface 263g) of 33 mm, a thickness (a distance between the front surface 263a and the rear surface 263f) of 30 mm, and the connecting groove 262 having a depth of 7 mm. The surfaces 263d and 263e forming the notch 261 have a width of 5 mm and a width of 9 mm, respectively, and the rear surface 263f has a width of 18 mm. The makeup stand 26 is formed to have a width smaller than that of the lower local stand 25 in order to give a sense of unity in accordance with the width of the facing makeup vertical frame 132 and to make the appearance in a clear and inconspicuous manner. .

Referring to FIG. 6, the connecting member 27 is a thin plate-like long member formed of a synthetic resin, and unevenness 271 is formed on the front and back thereof, and one of the width directions is a connecting groove 256 of the lower local 25. The other is a fitting portion 273 that fits in the connecting groove 262 of the decorative frame 26. The front and back irregularities 271 are formed in the fitting portions 272 and 273 so as to incline in the insertion direction and project in a sharp tip shape, and the tips of the fitting portions 272 and 273 are also formed in a sharp angle shape. This makes it easy to fit the fitting portions 272 and 273 into the connecting grooves 256 and 262, and once the fitting is made, the unevenness 271 bites into the groove inner surfaces of the connecting grooves 256 and 262 and does not easily come off. A state is obtained.

The thickness of the connecting member 27 is substantially the same as or slightly larger than the width of the connecting grooves 256 and 262 (3 mm in this embodiment), and the width (the total length of the fitting portions 272 and 273) is connected. The dimension is substantially the same as or slightly smaller than the total depth (14 mm) of the grooves 256 and 262. In this embodiment, the connecting member 27 has a length of 2469 mm, a width of 14 mm, and a thickness (including unevenness 271) of 4 mm. The connecting member 27 may be integrally formed of a single synthetic resin, but a soft resin is provided from the front ends of the fitting portions 272 and 273 to a part of the front and back surfaces while mainly using a hard resin. It may be formed.

The construction of the retractable door structure 10 shown in FIGS. 1 and 2 will be described with reference to FIG. FIG. 14 (a) shows the base process, in which the base vertical frame 131 is attached to the pillar 11, the door stop member 14 is attached to the pillar 12, and the door-case side upper frame 33 is attached to the upper surface of the opening 29. A door pocket base material 19 composed of a door pocket base plate 17 and a door pocket base rail 18 is attached to the lower surface and the pillar 12, and a gypsum board 21 is attached to the outer surface of the door pocket base material 19 to form door pockets 23, 23 on the front and back sides. A lower local 25 is attached to the opening end. At this time, the side surface of the door pocket base material 19 and the side surface 333a (FIG. 9A) of the stepped portion 333 of the door pocket side upper frame 33 are flush with each other, and the rear surface 253h of the lower locality 25 comes into contact therewith, A part of the local 25 is accommodated in the stepped portion 333 of the door pocket side upper frame 33. The lower locality 25 is fixed to the side surface of the door pocket base material 19 with screws (not shown), but does not contact the stepped side surface 333b (FIG. 9 (a)) of the door pocket side upper frame 33. A gap of about 1 to 3 mm is provided in the front. By doing in this way, even if the processing precision of the lower locality 25, the opening side upper frame 32, etc. is bad, construction of the lower locality 25 in a predetermined position is not prevented. The door pocket side upper frame 33 may be attached to the upper surface of the opening 29 after the door pocket side head rail 242 is fitted and fixed in advance and integrated. A gypsum board 21 is attached to the outer surface of each door pocket base material 19, its end is placed in the notch 255 of the lower locality 25, and a putty (not shown) is filled in the gap 28, and the seam with the outer surface 253 d of the lower locality 25 Is substantially flat.

(You can do this any time before you do). That is, on the door pockets 23 and 23 side, the cloth 22 is pasted so as to completely cover the protrusion outer surface 253d and the front surface 253c of the lower locality 25 from the surface of the gypsum board 21. Since the depth of the notch 255 in the lower locality 25 (the interval between the protrusion outer surface 253d and the base body outer surface 253g) is substantially equal to the thickness of the gypsum board 21, it extends from the surface of the gypsum board 21 to the outer surface 253 of the lower locality 25. When the cloth 22 is continuously pasted, a smooth decorative surface having no step is obtained even at the joint between the gypsum board 21 and the lower locality 25. Similarly, on the side of the pillar 11, the cloth 22 is attached so as to cover the outer surface and the front surface of the base vertical frame 131 from the surface of the gypsum board 21.

Next, as shown in FIG. 14C, the vertical frame 13 is formed by attaching the decorative vertical frame 132 to the base vertical frame 131 on the column 12 side, and the opening-side upper frame 32 is continuous with the doorcase-side upper frame 33. Is attached to the upper surface of the opening 29 to form the upper frame 15, and the opening side rail 241 is attached so as to be continuous with the door pocket side head rail 242 to form the head rail 24. The opening-side upper frame 32 may be attached to the upper surface of the opening 29 after the opening-side head rail 241 is fitted and fixed in advance. Although not shown, a sill rail 31 is attached to the floor 30 immediately below the duck rail 24. Further, the fitting portion 272 of the connecting member 27 is fitted into the connecting groove 256 of each lower locality 25, and the other fitting portion 273 is projected from the opening 29.

FIG. 14 (d) shows the finishing process. The sliding door 16 is suspended from the Kamoi rail 24, and the fitting portion 273 of the connecting member 27 in the protruding state in FIG. The makeup stand 26 is attached to the lower locality 25 by being inserted into the connecting groove 262 and fitting. Alternatively, in FIG. 14C, the connecting member 27 is not fitted into the connecting groove 256 of the lower local 25, and the fitting portion 273 of the connecting member 27 is fitted into the connecting groove 262 in FIG. By bringing the makeup stand 26 in the closed state close to the lower locality 25 and inserting the protruding fitting portion 272 into the connecting groove 256 of the lower locality 25 so as to integrate them. Also good. The stand 20 obtained by integrating the lower locality 25 and the makeup stand 26 as described above includes a tip end surface 322 of the opening-side upper frame 32 and stepped side surfaces 333a and 333b of the door-case side upper frame 33. It is housed in the vertical housing recess 34 (FIG. 12) to be formed. That is, the rear surface 253h of the lower local stand 25 abuts against the stepped side surface 333a of the door pocket side upper frame 33, and the front surface 263a of the makeup stand 26 abuts against the front end surface 322 of the opening side upper frame 32, and these inner surfaces 253i. , 263 g are flush with each other, and a part (inner part) of the lower local 25 and the makeup stand 26 is received in the stand receiving recess 34. As shown in FIG. 1, the makeup stand 26 is fixed to the opening-side upper frame 151 in a so-called vertical winning manner.

At this time, the front surface 253a of the lower district 25 and the rear surface 263f of the makeup stand 26 are in contact with each other, and the inner surface 253i of the lower district 25 and the inner surface 263g of the makeup stand 26 are substantially flush with each other. Form. Further, the protruding portion 252 of the lower local 25 is housed in the notch 261 of the makeup stand 26, but from the dimensional relationship described above, the protruding portion side surface 253b and the front surface 253c of the lower local 25 are notched surfaces of the makeup stand 26. 263d and 263e are maintained in a non-contact state, and a gap is secured between these surfaces. That is, in the lower locality 25, the distance from the upper surface of the connecting groove 256 to the protruding portion side surface 253b is a1, the width of the protruding portion side surface 253b is a2, and in the decorative stand 26, from the upper surface of the connecting groove 262 to the notch surface 263e. Is b1, and the width of the cut-out surface 263 is b2, a1> b1 and b2> a2 (FIG. 3). Therefore, when the makeup stand 26 is assembled and integrated with the lower locality 25 as described above, even if the processing accuracy of the lower locality 25 and / or the makeup stand 26 is poor, the connecting grooves 256 thereof. , 262 are matched with each other and can be connected by the connecting member 17. Further, the cloth 22 attached so as to completely cover the outer surface 253d, the inclined surface 253e and the front surface 253c of the lower locality 25 and the surfaces 263g, 263a to 263e of the makeup stand 26 are completely covered with The decorative sheet 264 attached so that both ends wrap around the rear surface 263f is not damaged.

According to this construction method, the cover 22 is attached (FIG. 14 (a)) after the doorcase-side upper frame 33 to which makeup is not applied is attached (FIG. 14 (b)), and then the opening is applied with makeup. Since the upper frame 15 is completed by attaching the side upper frame 32 and continuing to the doorcase side upper frame 33 (FIG. 14 (c)), the opening side upper frame 32 is damaged when the cloth is pasted. Does not cause peeling or damage. Although the doorcase side upper frame 33 is already attached at the time of the cross-pasting operation, since the makeup is not applied to the doorcase side upper frame 33, it is not necessary to cover with a curing sheet to prevent damage.

Moreover, in the retractable door structure 10 constructed as described above, if the opening-side upper frame 32 or the opening-side head rail 241 is damaged and needs to be repaired or replaced after the construction, the door pocket 23 is not broken. However, it is possible to perform repair or replacement work simply by removing the opening-side upper frame 32 and the opening-side head rail 241, thereby reducing work effort and work time.

The joint J1 between the opening side upper frame 32 and the door pocket side upper frame 33 and the joint J2 between the opening side head rail 241 and the door pocket side rail 242 are both outside the door pocket 23 (inside the opening 29). ), It is easy to attach / remove the opening-side upper frame 32 and the opening-side head rail 241.

Further, as described above, the lower local stand 25 and the makeup stand 26 are the vertical accommodation recesses formed by the tip end surface 322 of the opening-side upper frame 32 and the stepped side surfaces 333a and 333b of the door-case upper frame 33. 34 (FIG. 12), and the joint J1 between the opening side upper frame 32 and the door pocket side upper frame 33 and the joint J2 between the opening side head rail 241 and the door pocket side rail 242 are both makeup methods. Since the front surfaces 263a of the uprights 26 and 26 are substantially flush with each other and are positioned at the approximate center in the width direction of the makeup stand 26 and 26, these joints J1 and J2 are concealed by the make-up stand 26 and 26 and the door pocket. It becomes invisible from the outer side (front side) of 23, and appearance is not impaired.

The retractable door structure 10 shown in FIGS. 15 and 16 is similar to the retractable door structure 10 of the first embodiment. However, the retractable door structure 10 is composed of the vertical frame 13, the upper frame 15, the Kamoi rail 24, and the vertical 20 that are constituent members thereof. There is a difference. Hereinafter, these will be mainly described, and the description of the same components and operations as those of the first embodiment will be omitted. In addition, the same reference numerals are given to members and elements that are the same as or correspond to those in the first embodiment.

The vertical frame 13 is shown as consisting of two members, a base vertical frame 131 and a decorative vertical frame 132. In this embodiment, the vertical frame 13 has a shape and a configuration in which these are combined and integrated, It is a single member having a decorative sheet 136 affixed to at least the exposed surface during construction. The vertical 20 is also shown in the first embodiment as being composed of two members, the lower local 25 and the decorative vertical 26, but in this embodiment, the shape is a combination of these two. And a single member having a decorative sheet 201 affixed on at least the exposed surface during construction.

The upper frame 15 is also composed of two members, the opening-side upper frame 32 and the door-bag-side upper frame 33, as in Example 1, in this embodiment, but in Example 1, these have the same length. On the other hand, in this embodiment, the opening side upper frame 32 is formed longer than the door pocket side upper frame 33. That is, as shown in FIG. 17, the opening-side upper frame 32 of this embodiment has a substantially rectangular shape in plan view, but the tip is formed narrowly via the step portions 320, 320 on both sides in the width direction, and the wide portion 32A and the narrow part 32B. The total length including the wide portion 32 </ b> A and the narrow portion 32 </ b> B is substantially half of the left-right width of the opening 29. The width of the wide portion 32 </ b> A is smaller than the opening-side upper frame 32, and is large enough to fit between the front and back door pocket base materials 19, 19. The cross-sectional shape of the opening-side upper frame 32 is substantially U-shaped through the wide portion 32A and the narrow portion 32B, and the door of the opening-side head rail 242 to be described later is located in the center in the width direction of the surface 326 that is the lower surface in the construction state. The Kamoi rail attachment recessed part 325 including the groove | channel 324 which fits and accommodates the running groove 244 is formed. The groove 324 is recessed so as to continuously extend linearly over the entire length in the longitudinal direction of the opening-side upper frame 32 through the wide portion 32A and the narrow portion 32B. The thickness of the wide portion 32 </ b> A is the same as the thickness of the door pocket side upper frame 33.

On the other hand, the door pocket side upper frame 33 of this embodiment is formed by cutting out the narrow portion 335 of the door bag side upper frame 33 of Example 1 and including only the wide portion 334, as shown in FIG. . If necessary, the cut-off narrow part 335 is made continuous with the distal end side of the opening-side upper frame 32 of Example 1 to form a narrow part 32B, whereby the opening-side upper frame 32 of this embodiment is formed. . As an example of the length, the opening side upper frame 32 is 790 mm (the wide part 32A is 734 mm, the narrow part 32B is 56 mm), the door side upper frame 33 is 774.5 mm, the opening side head rail 241 is 762 mm, the door side The Kamoi rail 242 is 802.5 mm.

The opening-side Kamoi rail 241 and the door-bag side Kamoi rail 242 constituting the Kamoi rail 14 are the same planar shape and cross-sectional shape as the opening-side Kamoi rail 241 (FIG. 8) and the door-bag side Kamoi rail 242 (FIG. 10) of the first embodiment. The width and height (depth) dimensions are the same, but the length relationship with respect to the opening side upper frame 32 and the door pocket side upper frame 33 is different. That is, in Example 1, since the opening side upper frame 32 and the opening side head rail 241 are the same length, and the door pocket side upper frame 33 and the door pocket side head rail 242 are the same length, the opening side upper frame 32 is the same. Is the same position as the joint J1 (FIG. 19) when the door-side upper frame 33 is continuous with the joint J2 when the opening-side head rail 241 is connected to the door-side head rail 242 (FIG. 12). In this embodiment, the opening-side head rail 241 is shorter than the opening-side upper frame 32, and the door-bag side head rail 242 is longer than the door-bag-side upper frame 33, so that the opening-side upper frame 32 is made continuous with the door-bag-side upper frame 33. The seam J1 is different from the seam J2 when the opening side head rail 241 is connected to the door pocket side head rail 242 (FIG. 20).

The seam J1 between the upper frames 32 and 33 is substantially flush with the rear surfaces of the vertices 20 and 20, and is located at the approximate center in the width direction of the vertices 20 and 20, so that it cannot be seen from the outside and has a good appearance. To maintain. Moreover, since the joint J2 between the Kamoi rails 241 and 242 is also located at the approximate center in the width direction of the vertical towers 20 and 20, the appearance is not impaired. Moreover, since the joint J2 between the Kamoi rails 241 and 242 is located at the thickness range of the verticals 20 and 20 and substantially in the center in the width direction, it is not visible from the outside and maintains a good appearance.
