Description

  The present invention relates to a sliding door frame structure that houses a sliding door in an opening of a house or the like so as to be opened and closed.

  Such a sliding door frame structure is configured to include a left and right vertical frame, a duck laid across the upper ends of the left and right vertical frames, and a sill constructed on the floor foundation between the lower ends of the left and right vertical frames. . A rail that extends along the length direction (opening width direction) of the sill is formed with a Kamoi groove extending in the length direction (opening width direction). Is provided by integrally forming or by fitting a rail member in the sill groove, and by placing a door wheel attached to the lower end of the sliding door so as to be able to travel, the opening / closing of the sliding door is guided. In addition, the left and right vertical frames are extended with a door jacket along the length direction (height direction), and the door end of the sliding door is housed in a closed end (patent document). 1, 2).

  The door jacket is formed with a groove width slightly larger than the sliding door thickness corresponding to the thickness of the sliding door, whereas the Kamoi groove is formed with a groove width that accommodates the upper end convex part of the sliding door. Therefore, a gap member (an upper gap member 6b in FIG. 2 of Patent Document 1) having a groove corresponding to the groove shape of the Kamoi groove is fitted to the upper end of the door jacket. When the sliding door is closed and the sliding door is closed, the upper end convex portion of the sliding portion of the sliding door is accommodated in the concave groove of the gap member so as to be held free of rattling.

  By the way, a floor material is constructed on the floor base, and a sill is provided at a height corresponding to the upper surface (floor surface). However, the sills shown in Patent Documents 1 and 2 are made of a single member having a certain thickness, and can only deal with one kind of flooring. For this reason, when it becomes necessary to use floor materials having different thicknesses in the renovation, the sill has to be replaced, which requires a lot of labor, labor and cost.

  Patent Document 3 discloses a construction material that can be used as a sill composed of two members, an upper member having a rail that guides the traveling of a door cart and a lower member that is constructed on a floor base. In the case of, these two members are used in combination (Fig. 3), and in the case of a thin floor material, only the upper member is used (Fig. 4). I try to let them. However, Patent Document 3 does not mention any gap concealing member. As described above, the gap concealment member used to conceal the gap between the door jacket and the sill must be fitted in the lower edge groove of the door jacket with its upper surface approximately flush with the upper surface of the sill. However, the height of the top surface of the sill changes when the two members are used in combination and when only the upper member is used, and the gap concealing member also has a different height in the bottom groove of the door cover. Must be placed in position.

  When the gap concealment member is fitted and fixed in advance at a predetermined height position in the lower end groove of the door jacket, and assembled so that the upper surface of the sill is substantially flush with the upper surface (see FIG. 2 and FIG. 9 of Patent Document 2) and is fixed to the sill side so as to protrude from the butt end of the sill, and this is fitted to a predetermined height position in the bottom groove of the door cover and assembled. Cases (see paragraph 0021 of Patent Document 1 and FIG. 1 of Patent Document 2). In the former case, since the height position of the gap concealing member is fixed, it is not possible to cope with changing the usage of the sill member according to the thickness of the flooring as disclosed in Patent Document 3. In the latter case, if the gap concealing member is fixed so that the upper surface is substantially flush with the top surface of the upper member in a two-member sill as shown in Patent Document 3, the thickness of the flooring can be increased. Accordingly, when the usage of the sill member is changed, the height position of the gap concealing member is also changed, and the upper surfaces thereof can be kept substantially flush with each other. However, in this case, the position in the depth direction of the gap concealing member that is fixed to the top surface of the upper member must be strictly determined in relation to the door cover, and it is difficult to attach with high accuracy. If the gap concealing member fixed to the top end of the upper member is fixed at a position shifted from the door cover, the mounting position of the sill with respect to the vertical frame is also shifted.

  Accordingly, the problem to be solved by the present invention is that the upper and lower two members are used in the sliding door frame structure using the sill member composed of the upper and lower two members so as to correspond to the thickness of the floor material. The positioning of the sill member is easy through the gap concealment member that is fitted to the door cover, both in the case of using a combination of the above and in the case of using only the upper member to correspond to a thin floor material, and In addition, the positioning of the flooring material should be easy and accurate.

  In order to solve this problem, the present invention according to claim 1 is a three-way frame in which a duck is horizontally mounted on the upper ends of a pair of left and right vertical frames, a sill member constructed on a floor base, and at least one vertical frame. In the sliding door frame structure configured to have a gap concealment member that conceals the gap between the door jacket and the sill member formed on the inner surface of the door, the gap concealment member is a vertical frame. The sill member is a flooring material to be constructed on the floor base, having a fitting part that fits into a door-jam on the inner surface and a protruding part that protrudes horizontally from one side of this fitting part Depending on the thickness of the upper member, the upper member and the lower member can be used in two ways: a first usage in which the upper member is combined and a second usage where the upper member is used alone, and the surface of the upper member Is provided with a rail that guides the lower end of the sliding door so that it can run, and is provided with a protrusion fitting hole. A projection fitting groove is provided on the surface of the material, and both the projection fitting hole in the upper member and the projection fitting groove in the lower member have substantially the same width as the projection portion of the gap concealing member. The upper member and the lower member have substantially the same width dimension, and the protrusion fitting hole and the protrusion fitting groove are formed at positions corresponding to the width direction in the upper member and the lower member. A sliding door frame structure characterized by

  According to a second aspect of the present invention, in the sliding door frame structure according to the first aspect, the protruding portion of the gap concealing member is inserted into the protruding fitting hole in the upper member, and the lower surface of the protruding portion is set to the bottom surface of the protruding fitting hole. When fixed, the surface of the upper member is substantially flush with the surface of the fitting portion of the gap concealing member.

  According to a third aspect of the present invention, in the sliding door frame structure according to the first or second aspect, a rail fitting groove for removably fitting the rail member is formed on the surface of the upper member, and the rail fitting groove has a rail. A protrusion fitting hole is formed in the back of the rail fitting groove when the member is fitted.

  According to this invention which concerns on Claim 1, the clearance gap concealment member which hides the clearance gap between the door jacket and the sill member of the inner surface of a vertical frame comprises the fitting part fitted by a door pocket, and a sill member. Since it has the protrusion part which fits and is fixed to the protrusion fitting hole formed in the upper member, the planar positional relationship between the vertical frame and the sill member is determined by the gap concealing member. Since the protrusion of the gap concealment member can be inserted into the protrusion fitting groove of the lower member, first, the lower member is positioned with respect to the vertical frame via the gap concealment member during construction. Thus, the flooring material can be laid, and the installation work of the sill member and the laying work of the floor board can be easily performed.

  In addition, the sill member is a first usage in which the upper member and the lower member are combined and a second usage in which the upper member is used alone, depending on the thickness of the floor material to be constructed on the floor base. Therefore, there is no need to replace the sill when renovating, and there is an effect that it can be applied to floor materials of different thicknesses by a simple operation.

  According to the second aspect of the present invention, when the protrusion of the gap concealment member is inserted into the protrusion fitting hole in the upper member and the lower surface of the protrusion is fixed to the bottom surface of the protrusion fitting hole, Since the surface and the surface of the fitting portion of the gap concealing member are substantially flush with each other, the surface of the gap concealing member is the surface of the sill member (upper member) regardless of the usage of the sill member It has the effect of being able to hide the gap between the door jacket and the sill member nicely.

  According to the third aspect of the present invention, the rail fitting groove for removably fitting the rail member is formed on the surface of the upper member, and in the state in which the rail member is fitted in the rail fitting groove, the inner side thereof Since the projection fitting hole is formed using the remaining space, the projection fitting hole can be formed without requiring troublesome processing work, and the upper member is arranged with the rail member removed at the time of construction. Since the gap concealing member can be arranged so that the protruding portion is placed on the protruding fitting hole later, there is an effect that the construction is facilitated.

  First, the sliding door frame structure according to the present invention will be outlined. The sliding door frame structure is provided at the opening of the building, and has a three-sided frame in which the duck is horizontally mounted on the upper ends of a pair of left and right vertical frames, a sill member constructed on the floor base, and an inner surface of at least one vertical frame It has a gap concealing member that conceals the gap between the formed door jacket and the sill member. Depending on the structure and size of the opening of the building where the sliding door frame is installed, it can be applied as various types of sliding door frame structures such as a single-drawing type, a sliding type, a drawing type, a three-drawing type, and a four-drawing type. There are no particular restrictions on the material of the vertical frame and the duck that make up the three-sided frame, but in general, wood-based materials such as sawn timber, plywood, fiberboard, particleboard, glulam, and single-ply laminates are laminated individually or arbitrarily A composite material that is used for a base material as a material or that is optionally laminated with a base plate, a single plate, a synthetic resin sheet, a metal sheet, or the like may be used. These base materials may be used as they are, but at least a decorative material such as a veneer veneer, decorative paper, and a synthetic resin sheet may be attached to the part exposed to the outside after construction, or any pattern printing / coloring coating, etc. It is preferable to apply makeup.

  The sliding door provided inside the sliding door frame so as to be openable and closable is movable along a rail provided on the surface of the sill member. The number of sliding doors provided in the sliding door frame varies depending on the type of the sliding door frame. A door cart that runs along the rails of the sill member is attached to the bottom of the sliding door as necessary. When the sliding door is completely closed, the end of the sliding door's closed end is housed in a door plow formed in the vertical frame, and light leakage from the gap between the sliding door and the vertical frame and airflow are removed. To prevent. Therefore, the door jacket is formed by extending in the length (height) direction of the vertical frame on at least the inner side surface of the vertical frame facing the closed end of the sliding door. It has dimensions according to the number of types or the number of sliding doors.

  In this way, when a door scraper is formed on the inner side surface of the vertical frame to accommodate the closed side end of the sliding door, a gap is formed between the lower end and the sill member. Used. The gap concealing member has a fitting part that fits into the doors on the inner surface of the vertical frame, and a protruding part that protrudes horizontally from one side of this fitting part, and is made of wood, synthetic resin, metal An arbitrary material such as a material is formed by cutting or extrusion. The fitting portion has at least the upper end portion (upper end surface) substantially the same shape as the cross-sectional shape of the door jacket, and the fitting portion is plugged into the door jacket to close the gap between the sill member. Can do. The shape of the fitting portion other than the upper end portion is not particularly limited as long as it can be fitted and accommodated in a door. The protruding portion protrudes horizontally from one side surface of the fitting portion, and can be fitted into the protrusion fitting hole of the upper member and the protrusion fitting groove (both described later) constituting the sill member, and It is formed in such a shape and size that a sufficient bonding area is secured when it is bonded and fixed to the protrusion fitting hole of the member. When a plurality of protrusion fitting holes on the upper member and a plurality of protrusion fitting grooves on the lower member are provided, the protrusions are formed so that they can be inserted into at least one of them, and in order to obtain a stable mounting state, two or more It is preferable to form the protrusion so as to be able to be inserted into the protrusion fitting hole / projection fitting groove.

  The sill member is composed of an upper member and a lower member. These upper and lower members are all made of solid wood, plywood, wood fiberboard, particle board, flake board, oriented strand board, stick board, laminated wood, plastic, foam plastic, wood powder mixed plastic, etc. Using a synthetic resin material such as steel, metal materials such as steel, aluminum, and stainless steel, and other optional materials, it is formed to a length suitable for horizontal mounting at the bottom of the left and right vertical frames by cutting and extrusion molding. The If necessary, a makeup material such as a veneer veneer, decorative paper, or a synthetic synthetic resin sheet is attached, or optional makeup is applied by pattern printing or coloring.

  A rail fitting groove for fitting the rail member is formed on the surface side of the upper member. Rail fitting grooves are provided in a number corresponding to the number of sliding doors provided in the sliding door frame. The rail member allows the sliding door to be opened and closed smoothly. When the door is attached to the lower end of the sliding door or the lower end of the sliding door from any material such as a synthetic resin material or metal material, a predetermined shape that can fit the door Formed. The rail fitting groove has a depth sufficient to form a protrusion fitting hole in the back in a state where the rail member is fitted. The protrusion fitting hole is formed to have substantially the same width as the protrusion of the gap concealing member, and has a height substantially equal to or greater than the thickness of the protrusion so that the protrusion can be inserted. The

  A protrusion fitting groove is formed in the center in the width direction of the surface of the lower member. Similar to the protrusion fitting hole formed in the upper member, the protrusion fitting groove is formed to have substantially the same width as the protrusion of the gap concealing member, and has a height substantially equal to or greater than the thickness of the protrusion. And is formed so that the protrusion can be inserted.

  In the present invention, the sill member is a first usage in which the upper member and the lower member are combined in accordance with the thickness of the floor material to be applied to the floor base, and the upper member is used alone. 2 can be used in two ways, but in any of the usages, in the sliding door frame after construction, the projection of the gap concealment member is fitted in the projection fitting hole of the upper member It is fixed with. During the construction, the lower member is positioned in a plane with respect to the vertical frame by fitting the fitting portion of the gap concealing member into the door and by fitting the protruding portion into the protruding fitting groove of the lower member. A floor material can be applied to the lower member, and in order to realize this, a protrusion fitting groove into which the fitting portion can be fitted is formed in the lower member. In the case of using the first usage in which the upper member and the lower member are used in combination, after fixing the lower member to the floor base, the upper member is fixed thereon to form a sill member, and the second usage is used alone. When the floor material is used, the lower member is removed, the lower member is removed, the upper member is disposed in the vacant portion, and is fixed to the floor base to form a sill member.

  The upper member and the lower member are formed with equal width dimensions. Here, the width dimension of the upper member and the lower member is a width dimension defined by both side surfaces of the upper member and the lower member with which the floor of the floor material is abutted during construction, and when the upper member is provided with a flange portion This collar portion is not included. By forming the upper member and the lower member to have substantially the same width in this way, after the floor material is constructed based on the lower member in the second usage, the upper member is fitted between the floor materials at the location where the lower member is removed. Can be arranged.

  Further, the protrusion fitting hole in the upper member and the protrusion fitting groove in the lower member are formed so that the positions in the width direction coincide with each other. Thus, after positioning the lower member by fitting the projection of the gap concealing member fitted to the door cover into the projection fitting groove of the lower member, the projection is moved to the upper member (in the first usage). The upper member disposed on the lower member, and in the second usage, the upper member disposed in place of the lower member) can be fitted without causing a displacement in the width direction. . The height position of the upper member is different between the case of the first usage and the case of the second usage. In this way, the projection fitting hole of the upper member and the projection fitting groove of the lower member are aligned in the width direction. Therefore, even if the height changes, the upper member and the lower member can be attached with high accuracy in correspondence with the position of the door.

A rail fitting groove 215 is formed over the entire length in the center in the width direction, and the rail member 216 is fitted into the rail fitting groove 215. The rail fitting groove 215 has a groove depth larger than the height of the rail member 216. Therefore, in a state where the rail member 216 is fitted, a space is left below the rail member 216, and this space is the gap concealment member 30 described above. This is a projection fitting hole 217 into which the projection 32 is fitted. Although the dimension of the upper member 21 is not limited, in this embodiment, the thin plate-like main body 211 has a width Wc (not including the collar portions 213 and 213) of 50 mm, a thickness of 3.0 mm, and a length of 3200 mm. The height of the leg portions 212, 212 (= depth of the recesses 214, 214) corresponds to the thickness of the floor material used when only the upper member 21 is used alone as the sill member 20, and in this embodiment, 7.0 mm. A bottom surface 218 at the center in the width direction having the rail fitting groove 215 is flush with the tips of the legs 212 and 212. The protrusion fitting hole 217 has a width Wd = 7.1 mm and a height of 2.0 mm, and the thin plate-like protrusion 32 (width Wb = 7.0 mm, height (thickness) = 1) of the gap concealing member 30. .5 mm) is suitable for fitting. In addition, the upper member 21 is created as a long material, and is used by cutting it to a required length on site according to the dimension between the vertical frames 11 and 11.

  Referring to FIG. 6, the lower member 22 has a symmetrical shape with respect to the center line X in the width direction, and protrusions 222, 222 are formed over the entire length near the left and right ends of the upper surface of the thin plate body 221. A projection fitting groove 223 is formed over the entire length in the center of the direction. When the lower member 22 is used in combination with the upper member 21 (FIGS. 1, 2, and 7), the protrusions 222 and 222 are fitted into the recesses 214 and 214 between the leg portions 212 and 212 of the upper member 21. In order to maintain this fitted state and not easily disengage, the inner surfaces of the leg portions 212 and 212 and / or the outer surface of the ridges may be provided with fine irregularities as shown in the figure. preferable. Moreover, when the lower member 22 is combined with the upper member 21, both side surfaces in the width direction of these both members are flush with each other (FIG. 7). The protrusion fitting groove 223 fits the thin plate-like protrusion 32 of the gap concealing member 30 described above. As long as these are satisfied, the size of the lower member 22 is not limited, but in this embodiment, the width is the same as the thin plate-like main body 211 of the upper member 21, Wc = 50 mm, thickness 5.0 mm, length 3200 mm. The protrusions 222 and 222 have a width of 5.0 mm and a height of 5.5 mm, and the protrusion fitting groove 223 has a width Wd = 7.1 mm and a depth of 2.0 mm.

It fits in the chest 14 (FIGS. 8B and 9). As a result, the lower member 22 is positioned at a predetermined position in a plane with respect to the vertical frames 11, 11. After fixing the lower member 22 to the floor base 4 with screws (not shown) at this position, The floor materials 5 and 5 are laid on the floor base 4 while the thick floor materials 5 and 5 are abutted against the both ends of the floor material 5 (FIG. 8C). In this way, it is possible to easily position the floor materials 5 and 5 with the lower member 22 as a reference.

  Thereafter, the gap concealing member 30 fitted in the door jacket 14 and the protrusion fitting groove 223 is once removed, and the upper member 21 is fitted and fixed on the lower member 22 fixed to the floor base 4 and integrated. To do. More specifically, an adhesive is applied to the back surface of the thin plate-like main body 211 of the upper member 21 and / or the upper surface of the thin plate-like main body 221 of the lower member 22 with the rail member 216 removed, and the leg portions 212, By fitting the protrusions 222, 222 of the lower member 22 into the recesses 214, 214 between the two members 212, these two members are fixed together. In addition to adhesion and fitting, it may be firmly fixed using screws (not shown). After the upper member 21 is fixed and integrated with the lower member 22 in this way, an adhesive is applied to the groove bottom of the rail fitting groove 215 opened on the upper surface of the upper member 21 and is removed from the lower member 22. The fitting portion 31 of the gap concealing member 30 is fitted to the door pocket 14, the protrusion 32 is fitted into the rail fitting groove 215, and is fixed to the groove bottom, and the rail member 216 is fitted thereon. Then, the adhesive is fixed with an adhesive (FIG. 8D). Alternatively, after the rail member 215 is fitted and bonded and fixed in the rail fitting groove 215 of the upper member 21, the protruding portion 32 of the gap hidden member 30 removed from the lower member 22 is left below the rail member 216. It fits in the joint hole 217 and is bonded and fixed to the groove bottom, and then the upper member 21 is bonded and fixed to the lower member 22 so that the fitting portion 31 of the gap concealing member 30 is fitted to the door jacket 14. Also good.

  In this way, the gap concealment member 30 is attached in the state as shown in FIGS. 2 and 3, and the gap between the sill member 20 is hidden by the fitting portion 31 fitted to the door scraper 14. Can do. In this state, the upper end portion 31 a of the fitting portion 31 of the gap concealing member 30 is flush with the upper surface of the thin plate-like main body 211 of the upper member 21 constituting the sill member 20. Further, as described above, in the combined sill member 20, the height to the lower surface of the collar portion 213 of the upper member 21 is the same as the thickness of the floor material 5, so that the collar portions 213 and 213 are connected to the floor material 5, 5 can be covered while being in close contact with the surface.

  Next, when a thin flooring 6 (thickness 7 mm) is constructed, the upper member 21 is used alone as the sill member 20 as shown in FIG. As described above, the height (Hb = 7 mm) of the leg portions 212 and 212 protruding from the lower surface of the thin plate-like main body 211 in the upper member 21 is the same as the thickness of the floor material 6. , 212, the collar portions 213 and 213 can be covered with the surfaces of the floor materials 6 and 6 in close contact with the outer surfaces 219 and 219 of the floor materials 6 and 216. At this time, the gap concealing member 30 has a fitting portion 31 fitted into the door scraper 14 of the vertical frame 11 and a protruding portion 32 formed at the center in the width direction of the upper member 21. It is in the state fitted in the hole 217 (FIGS. 3 and 10).

  The construction method in this case will be described. In this case, only the upper member 21 is finally used as the gap concealing member 30, but in this case also, the lower member 22 is used as a reference member for positioning, and the thick flooring 5 is applied. Similarly to the case where the protrusions 32 of the gap concealing member 30 are fitted in the protrusion fitting grooves 223 of the lower member 22 (FIG. 8A), the fitting part 31 of the gap concealing member 30 is vertically moved. It is made to fit in the door punch 14 of the frame 11 (FIG.8 (b), FIG.9). As a result, the lower member 22 is positioned at a predetermined position in a plane with respect to the vertical frames 11, 11, so that the floor materials 6, 6 are attached to the opposite side surfaces 224, 224 while abutting the ends of the thin floor materials 6, 6. It is laid on the floor base 4 (FIG. 12 (a)). In this manner, the floor materials 6 and 6 can be easily positioned with the lower member 22 as a reference.

  In this case, since the lower member 22 is not screw-fixed to the floor base 4, after the floor materials 6 and 6 are constructed, the lower member 22 and the gap concealing member 30 are removed (FIG. 12B), and the upper member 21 is removed. An adhesive is applied to the back surface of the floor, and is fitted between the flooring materials 6 and 6 and fixed to the floor base 4. In addition to the adhesive, screws (not shown) may be used to firmly fix the adhesive. After fixing the upper member 21 to the floor base 4 in this way, an adhesive is applied to the bottom of the rail fitting groove 215 opened on the upper surface of the upper member 21 from which the rail member 215 has been removed in advance. The fitting portion 31 of the gap concealing member 30 removed from the lower member 22 is fitted to the door jacket 14, the projection 32 is fitted into the projection fitting hole 217, and is adhered and fixed to the groove bottom. The rail member 216 is fitted and fixed with an adhesive (FIG. 12C). Alternatively, after the rail member 215 is fitted and bonded and fixed to the rail fitting groove 215 of the upper member 21, the protruding portion 32 of the gap hidden member 30 removed from the lower member 22 is left below the rail member 215. It fits into the hole 217 and is bonded and fixed to the groove bottom, and then the upper member 21 is fixed to the floor base 4 so that the fitting portion 31 of the gap concealing member 30 is fitted to the door jacket 14. good.

  In this way, the gap concealing member 30 is attached in the state as shown in FIGS. 11 and 2, and the gap between the sill member 20 (upper member 21) by the fitting portion 31 fitted to the door scraper 14. Can hide the gap. In this state, the upper surface of the fitting portion 31 of the gap concealing member 30 is flush with the upper surface of the thin plate body 211 of the upper member 21. Further, as described above, in the combined sill member 20, the height to the lower surface of the collar portion 213 of the upper member 21 is the same as the thickness of the floor material 6, so that the collar portions 213 and 213 are connected to the floor material 6, 6 can be covered while closely contacting the surface.

  The gap concealing member 30 used in the sliding door frame structure 10 includes a fitting portion 31 having at least an upper end portion 31 a having a planar shape substantially the same as the cross-sectional shape of the door scraper 14 on the inner surface of the vertical frame 11, and the upper member 21. It is essential that the projection fitting hole 217 or the projection portion 32 that protrudes in the horizontal direction so as to be fitted in the projection fitting groove 223 in the lower member 22 is configured. If it is, it can have various shape variations. For example, like a gap concealing member 30A shown in FIG. 13, a rectangular columnar downward projecting part 31d projecting downward from the center of the lower surface of the elongated plate-like upper end part 31a is made more than the downward projecting part 31b of the gap concealing member 30 shown in FIG. It may be formed wide.

  Further, the protruding portion 32 does not necessarily protrude from the lower end of the fitting portion 31, and a square protruding downward from the center of the lower surface of the elongated plate-shaped upper end portion 31a as in the gap concealing member 30B shown in FIG. The height of the columnar lower protrusion 31e may be increased so that the protrusion 32 protrudes horizontally from the middle in the height direction. In this way, there is an advantage that the protrusion 32 is not easily broken and easily damaged. In addition, when employ | adopting the shape which made the projection part 32 protrude from the height direction middle of the fitting part 31 like FIG. 14, when using the upper member 21 independently as a sill member (FIG. 10, FIG. 11). The height position of the lower surface 32a of the projecting portion 32 (the height to the lower surface 31c of the fitting portion 31) is the thickness of the bottom portion of the upper member 21 (from the bottom surface 218 at the center portion in the width direction) so as not to buffer the floor base 4. The height of the rail fitting groove 215 up to the groove bottom surface is not exceeded. Further, the height from the lower surface 32a of the protruding portion 32 to the upper surface of the fitting portion 31 is the same as that of the gap concealing member 30 in FIG. 4, and the protruding portion 32 is fitted and fixed to the protruding fitting hole 217 of the upper member 21. When this is done, the height positional relationship is secured so that the upper surfaces of the gap concealing member and the upper member 21 are flush with each other.

  Since the sliding door frame structure 10 of the embodiment described above is a single-drawing type, the upper member 21 of the sill member 20 has one rail fitting groove 215, and one rail member 216 is fitted into this. There is also one protrusion fitting hole 217 that is fixed and formed in the rail fitting groove 215, and therefore the gap concealing member also has one protrusion 32, which is connected to the protrusion fitting hole 217 of the upper member 21. It is inserted into and fixed by adhesion. However, if the type of sliding door frame is different, the number of rail fitting grooves 215 and projection fitting holes 217 provided in the upper member 21 is changed accordingly, and the number corresponding to the number of projection fitting holes is also provided in the gap concealing member. Can be provided. For example, in the case of a sliding type sliding door frame structure, the upper member 21 is provided with two rail fitting grooves 215 and two projection fitting holes 217. It is preferable to provide two protrusions. An example of the gap concealing member is shown in FIG. 15, and two rectangular pillar-shaped lower projecting portions 31b and 31b project from the lower surface of the wide thin plate-shaped upper end portion 31f at a predetermined interval, and each of the lower projecting portions 31b On one side surface, a thin plate-like protrusion 32 projects horizontally from the lower end to form a gap concealing member 30C. Although the shape of the downward protrusion 31b and the protrusion 32 is substantially the same as that of the gap concealing member 30 in FIG. 4, it is needless to say that these shapes may be modified as shown in FIGS. It is.

  When the upper member 21 has a plurality of protrusion fitting holes 217, it is not always necessary to provide the same number of protrusions 32 as the protrusion fitting holes 217 in the gap concealing member 30, and the number of protrusion fitting holes 217 (n1) And the number of protrusions 32 (n2) may satisfy the relationship (n1 ≧ n2). When the number (n2) of the protrusions 32 is smaller than the number (n1) of the protrusion fitting holes 217, two protrusions positioned at least at both ends in the width direction among the protrusion fitting holes 217 formed in the upper member 21. When the protrusions 32 and 32 are provided in the gap concealing member 30 so as to fit into the fitting holes 217 and 217, respectively, the gap concealing member 30 can be stably fixed to the wide upper member 21. Since the upper surfaces thereof are flush with each other and the gap between the door jacket and the sill can be clearly and concealed, this is a preferred embodiment. FIG. 16 shows a gap concealing member 30D as an example. This gap concealing member 30D has a thin plate-like upper end 31g formed wider than the upper end 31f of the gap concealing member 30C of FIG. 15, and similarly formed downward projecting portions 31b, 31b and projecting portions 32, 32. However, it is needless to say that these shapes may be modified as shown in FIGS.

  In the illustrated embodiment, a rail fitting groove 215 is provided on the surface of the upper member 21, the rail member 216 is detachably fitted thereto, and the rail member 216 is fitted in the rail fitting groove 215. The protrusion fitting hole 217 is formed by utilizing the space left behind, but instead, the rail member is fixed to the upper member, or the lower end of the sliding door or the cart can be driven A rail for guiding to the upper member 21 may be integrally formed on the surface of the upper member 21. In the case of adopting such an embodiment, the protrusion is fitted so as to have substantially the same width direction / height direction dimensions at substantially the same width direction / height direction position as the protrusion fitting hole 217 in the above-described embodiment. A joint hole is formed so that the protrusion 32 of the gap concealing member 30 can be inserted. In this case, the protrusion fitting hole may be formed so as to extend over the entire width (Wc) of the upper member 21, but the protrusion length of the protrusion 32 is substantially equal to both ends in the width direction where the protrusion 32 is inserted. You may dent so that it may have the same or more depth. Further, as a construction method in this case, the lower member 22 is fixed to the floor base 4 while being positioned in the width direction with respect to the door jacket 14 via the gap concealing member 30 (first usage) or simply disposed (first). 2), the protrusions 32 of the gap concealment member are inserted into the protrusion fitting holes at both ends in the width direction of the upper member 21 on which the rail is fixed or integrated, and then bonded and fixed to the groove bottom. The upper member 21 is bonded and fixed to the lower member 22 so that the fitting portion 31 of the gap concealing member 30 is fitted to the door jacket 14.

  In addition, the protrusion fitting groove 223 formed in the lower member 22 is also formed to extend over the entire width (Wc) of the lower member 22 in the illustrated embodiment. Similar to the protrusion fitting hole 217 of the member 21, it is for fitting the protrusion 32 of the gap concealing member 30 so that it is substantially the same as the protrusion length of the protrusion 32 at both ends in the width direction where the protrusion 32 is inserted. You may make it recessed so that it may have the above depth.
