Description

Technical Field

[0001] The present invention relates to a structure and a construction method for a two-sided frame for constructing a two-sided frame in an opening extending from a floor surface to a ceiling surface formed on an interior wall.

Background Art

[0002] In recent years, in buildings such as houses, a fitting device (so-called high door) that opens and closes an opening reaching from the floor surface to the ceiling surface without providing a descending wall in the opening has been widely used. Further, in order to finish this type of fitting device beautifully, there is a method of constructing so that the upper frame of the three-sided frame is embedded in the ceiling, making it appear as if a two-sided frame has been constructed (see, for example, Patent Document 1 below).

[0003] In the fitting device disclosed in Patent Document 1, before constructing the ceiling material, the three-sided frame is assembled and fixed in the opening, and then the ceiling material is constructed so that the lower surface of the ceiling material is flush with the lower surface of the upper frame. In the fitting device disclosed in Patent Document 1, by constructing the three-sided frame in such a way that the upper frame is embedded in the ceiling, it appears as if a two-sided frame without an upper frame has been constructed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the configuration of the above-described fitting device, although it is possible to make it appear as if a clean two-sided frame without an upper frame has been constructed, the work of fixing the ceiling material while adjusting the position so that the lower surface of the ceiling material and the lower surface of the upper frame are flush is not easy, and it is also necessary to separately construct members for position adjustment, resulting in a problem that the construction work becomes complicated.

[0006] The present invention has been made in view of such circumstances, and an object thereof is to enable easy construction of a two-sided frame in an opening extending from a floor surface to a ceiling surface.

Means for Solving the Problems

[0007] In order to achieve the above object, in the present invention, a construction structure is configured in which a connecting member that removably fixes at least the upper end portions of a pair of vertical frames forming a two-sided frame is removably fixed.

[0008] Specifically, a first invention is a construction structure for a two-sided frame for constructing a two-sided frame in an opening extending from a floor surface to a ceiling surface formed in an indoor wall, and includes a pair of vertical frames forming the two-sided frame, and a connecting member that connects at least the upper end portions of the pair of vertical frames in a vertical overlapping manner, and the connecting member is removably fixed to each of the vertical frames.

[0009] In the first invention, in order to construct a good-looking two-sided frame without an upper frame, a construction structure in which a connecting member that connects at least the upper end portions of a pair of vertical frames forming the two-sided frame in a vertical overlapping manner is removably fixed is used. According to such a construction structure, after fitting the construction structure into an opening extending from a floor surface to a ceiling surface formed in an indoor wall and fixing a pair of vertical frames, a good-looking two-sided frame without an upper frame can be easily constructed in the opening simply by removing the connecting member without performing complicated alignment.

[0010] A second invention is the first invention, wherein grooves for providing a door stop are formed on the inner surfaces of the pair of vertical frames facing each other, and the connecting member extends from the groove in one of the pair of vertical frames to the groove in the other of the pair of vertical frames and is removably fixed to each of the vertical frames.

[0011] In the second invention, a connecting member is removably bridged across a groove provided for a door stop of a pair of vertical frames. According to such a configuration, for example, even if a nail-shaped member such as a screw is used for fixing the connecting member, after removing the connecting member, the holes left by the nail-shaped member are hidden by the door stop and become invisible. Therefore, according to the second invention, a good-looking two-sided frame without an upper frame can be easily constructed in the opening without impairing the design.

[0012] A third invention is characterized in that, in the second invention, the connecting member is removably fixed to each of the vertical frames by a nail-shaped member driven so as to penetrate the connecting member from the space side sandwiched by the pair of vertical frames toward the inner surface of the groove.

[0013] By the way, the construction structure is fixed in the opening by being fixed to columns installed on both sides of the opening. Therefore, in the construction structure, if the connecting member is fixed to each vertical frame by driving a nail-shaped member from the outside of the pair of vertical frames toward the end of the connecting member, the nail-shaped member cannot be pulled out after the construction structure is constructed in the opening.

[0014] Therefore, in the third invention, the nail-shaped member for fixing the connecting member to each vertical frame is driven so as to penetrate the connecting member from the space side sandwiched by the pair of vertical frames toward the inner surface of the groove for the door stop into which the end of the connecting member fits. By driving the nail-shaped member in such a direction, it becomes possible to pull out the nail-shaped member after fixing the construction structure in the opening, and it becomes possible to remove the connecting member.

[0015] A fourth invention is characterized in that, in the second invention, the connecting member is provided so as to connect the upper end portions and the lower end portions of the pair of vertical frames, respectively.

[0016] In the fourth invention, the upper and lower ends of the pair of vertical frames are respectively connected by two connecting members, so that the pair of vertical frames can be easily and aesthetically constructed into the opening while maintaining a parallel positional relationship.

[0017] The fifth invention is a method for constructing a two-sided frame by constructing a two-sided frame from the floor surface to the ceiling surface formed between two columns on the wall inside the room. The method includes a fixing step of arranging the construction structure according to the first invention at a predetermined construction position within the opening and fixing the pair of vertical frames to the two columns installed on both sides of the opening, and a removing step of removing the connecting member from the construction structure fixed to the two columns.

[0018] The sixth invention is a method for constructing a two-sided frame by constructing a two-sided frame from the floor surface to the ceiling surface formed between two columns on the wall inside the room. The method includes a fixing step of arranging the construction structure according to any one of the second to fourth inventions at a predetermined construction position within the opening and fixing the pair of vertical frames to the two columns installed on both sides of the opening, a removing step of removing the connecting member from the construction structure fixed to the two columns, and a door stop construction step of respectively providing the door stops in the grooves of the pair of vertical frames.

[0019] In the fifth and sixth inventions, the construction structure is used for constructing the two-sided frame. After arranging the construction structure at a predetermined construction position within the opening and fixing the pair of vertical frames to the two columns installed on both sides of the opening, the connecting member is removed from the construction structure, so that only the pair of vertical frames that form the two-sided frame are constructed within the opening. According to such a construction method, a good-looking two-sided frame without an upper frame can be easily constructed within the opening without performing complicated alignment as in the prior art.

[0020] In the sixth invention, after removing the connecting member, a doorstop is provided in the grooves of a pair of vertical frames over which the connecting member was spanned. Therefore, for example, even if a nail-shaped member such as a screw is used for fixing the connecting member, after removing the connecting member, the holes left by the nail-shaped member are hidden by the doorstop and become invisible. Accordingly, according to the sixth invention, a good-looking two-sided frame without an upper frame can be easily constructed in the opening without impairing the design.

Effects of the Invention

[0021] As described above, according to the present invention, since a construction structure is configured in which a connecting member that removably fixes at least the upper end portions of a pair of vertical frames forming a two-sided frame is fixed in a vertically overlapping manner, it becomes possible to more easily construct a good-looking two-sided frame without an upper frame in an opening extending from the floor surface to the ceiling surface than in the prior art.

Modes for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the embodiments is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses in any way.

[0024] <<Embodiment 1 of the Invention>> FIG. 1 is a front view of a fixture device 1 including a two-sided frame 10 and a door (fixture) 50 constructed by the construction method of the two-sided frame according to the present invention within a rectangular opening O formed in an indoor wall W. FIG. 2 is a cross-sectional view of the fixture device 1, and FIG. 3 is a longitudinal sectional view of the fixture device 1. Hereinafter, for convenience of explanation, the left side, right side, upper side, and lower side of FIG. 1 will be described as "left", "right", "upper", and "lower", respectively. Also, the front side and the rear side in the direction perpendicular to the plane of FIG. 1 will be described as "front" and "rear", respectively.

[0025] As shown in FIGS. 1 to 3, the wall W is a wall of a large wall structure and is configured by fixing a plurality of wall base materials 3,..., 3 on both the front and rear sides of columns (including intermediate columns) 2,..., 2. The ceiling C is a suspended ceiling, and a plurality of ceiling materials (such as gypsum boards) 7,..., 7 are fixed to the lower ends of a plurality of ceiling edges 6,..., 6 fixed to a plurality of ceiling edge receivers 5,..., 5 fixed to a plurality of hanging woods (not shown), with the plurality of ceiling edges 6,..., 6 being fixed orthogonally to the plurality of ceiling edge receivers 5,..., 5. The opening O is formed between two columns 2, 2 within the wall W. The upper end of the opening O is demarcated by a ceiling surface Cs (the lower surface of a ceiling finishing material such as a cross) which is the decorative surface of the ceiling C, and the lower end of the opening O is demarcated by a floor surface Fs which is the decorative surface of the floor F. That is, the opening O is formed from the floor surface Fs to the ceiling surface Cs.

[0026] In the first embodiment, the fitting device 1 includes a two-sided frame 10 installed in the opening O of the wall W and a door 50. The door 50 is swingably attached to the two-sided frame 10 by upper and lower hinges 51, 51, and a lever 52 for opening and closing operations is attached thereto. The features of the present invention are a construction structure A and a construction method for easily constructing the two-sided frame 10. Hereinafter, the two-sided frame 10, the construction structure A, and the construction method will be described in detail in order.

[0027] -Detailed Configuration of the Two-Sided Frame- The fitting frame 10 is a two-sided frame without an upper frame and a lower frame, including a pair of vertical frames 11, 11. The fitting frame 10 is attached to the left and right ends of the wall W partitioning the opening O. In the first embodiment, the fitting frame 10 is attached to the inner surfaces (the surfaces on the opening O side) of the two columns 2, 2 in the wall W partitioning the opening O via spacers 4. The spacer 4 is composed of a long wooden plate material with a width equal to or less than the thickness of the wall W and a thickness of 10 to 20 mm. The fitting frame 10 is attached to the left and right ends of the wall W including the spacers 4. In the first embodiment, a pair of parting materials 12, 12 and a door stop 13 are attached to each vertical frame 11.

[0028] As shown in FIGS. 2 and 3, the pair of vertical frames 11, 11 have the same cross-sectional structure and are arranged symmetrically. The vertical frame 11 is, for example, a long wooden plate-like member extending in the vertical direction composed of a wooden material such as wood, plywood, medium-density fiberboard, particle board, or laminated wood, and has an H-shaped cross-section. The front and rear width (prospective dimension) of the vertical frame 11 is shorter than the thickness of the wall W, the thickness (found dimension) is 18 to 30 mm, and the vertical length is the same as the vertical length of the opening O (the distance between the floor surface Fs and the ceiling surface Cs). The vertical frame 11 is arranged in the opening O so that the outer surface abuts against the end face of the wall W (in the first embodiment, the inner surface of the spacer 4), and is fixed to the column 2 via the spacer 4 by an adhesive and nail-like members 41 such as nails, pin nails, and screws. Note that the vertical frame 11 may be composed of a resin material or a steel material.

[0029] On the front and rear surfaces of the vertical frame 11, grooves 15 extending vertically are formed in the middle in the left - right direction (the finding direction). The groove 15 is formed so as to extend from the upper end to the lower end of the vertical frame 11. The ends of a pair of partition members 12, 12 are inserted into the groove 15.

[0030] Also, on the inner surface of the vertical frame 11 (the surface where the pair of vertical frames 11, 11 face each other), a groove 16 extending vertically is formed in the middle in the front - rear direction (the prospective direction). The groove 16 is formed so as to extend from the upper end to the lower end of the vertical frame 11. The support leg 13b of the door stop 13 is inserted into the groove 16.

[0031] The partition member 12 is, for example, a long wooden plate - shaped member extending in the vertical direction composed of a wooden material such as wood, plywood, medium - density fiberboard, particle board, laminated wood, etc. The length in the vertical direction is formed to be the same as the length of the vertical frame 11. The partition member 12 has a vertical plate portion 12a extending in the prospective direction and a horizontal plate portion 12b extending in the finding direction from the end of the vertical plate portion 12a, and is formed in an L - shaped cross - section. The partition member 12 is arranged and fixed at a position where the end of the vertical plate portion 12a is inserted into the groove 15 formed in the front and rear surfaces of the vertical frame 11 and the end of the horizontal plate portion 12b abuts against the end of the wall W. The partition member 12 covers the joint between the vertical frame 11 and the end of the wall W. The partition member 12 may be composed of wood, or may be composed of a resin material or a steel material.

[0032] The door stop 13 is a long member extending in the vertical direction made of a resin material such as an ABS (Acrylonitrile Butadiene Styrene) resin, etc., and the length in the vertical direction is formed to be the same as the length of the vertical frame 11. The door stop 13 has a main body portion 13a and support legs 13b. The main body portion 13a has a U-shaped cross section. The support legs 13b are composed of two support legs protruding outward from the two ends of the main body portion 13a respectively. The two support legs are composed of plate-like pieces extending in the vertical direction and the finding direction (left and right direction), and are opposed to each other in the prospective direction (front and back direction). Engagement protrusions that engage with the inner surface of the groove 16 of the vertical frame 11 are formed at the outer ends of the two support legs. The door stop 13 is fixed to the vertical frame 11 with an adhesive or the like in a state where the support legs 13b are inserted into the groove 16 formed on the inner surface of the vertical frame 11.

[0033] Incidentally, although details will be described later, in the first embodiment, in addition to the role as a normal door stop, the door stop 13 also has the role of hiding the screw holes (nail holes) of the screws (nail-like members) 31 for fixing the connecting member 14 of the construction structure A to be described later.

[0034] -Construction structure for the two-sided frame- In the first embodiment, the construction of the two-sided frame 10 is facilitated by constructing the two-sided frame 10 using the construction structure A shown in FIGS. 4 to 6.

[0035] The construction structure A includes a pair of vertical frames 11, 11 that will form the two-sided frame 10, and a connecting member 14 that connects the pair of vertical frames 11, 11 in a vertically overlapping manner in a parallel state.

[0036] In Embodiment 1, the connecting member 14 is composed of a strip-shaped member extending in the left-right direction. The connecting member 14 is formed such that the thickness in the prospective direction (front-rear direction) is slightly thinner than the width in the prospective direction of the groove 16 so that the left and right ends fit into the grooves 16 provided for the door stops 13 formed on the inner surfaces of the vertical frames 11. The length of the connecting member 14 in the finding direction (left-right direction) is such that when the left and right ends of the connecting member 14 are inserted until they contact the groove bottoms in the grooves 16, 16 of the pair of vertical frames 11, 11 and fixed to each vertical frame 11, the pair of vertical frames 11, 11 are connected at a desired installation interval (the interval designed to allow the pair of vertical frames 11, 11 to be installed within the opening O).

[0037] In Embodiment 1, the pair of vertical frames 11, 11 are connected by two connecting members 14, 14. One of the two connecting members 14, 14 is provided so as to span between the upper end portions of the pair of vertical frames 11, 11 and connects the upper end portions. The other one of the two connecting members 14, 14 is provided so as to span between the lower end portions of the pair of vertical frames 11, 11 and connects the lower end portions.

[0038] Also, in Embodiment 1, each connecting member 14 extends from the groove 16 provided for the door stop 13 of one vertical frame 11 of the pair of vertical frames 11, 11 to the groove 16 provided for the door stop 13 of the other vertical frame 11 and is removably fixed to each vertical frame 11. By fixing each connecting member 14 to each vertical frame 11 with the left and right end faces of each connecting member 14 in contact with the groove bottom surfaces of the grooves 16, 16 of the pair of vertical frames 11, 11, the pair of vertical frames 11, 11 are connected with the above-described desired installation interval therebetween.

[0039] In Embodiment 1, the connecting member 14 is removably fixed to each vertical frame 11 with screws (nail-shaped members) 31.

[0040] Specifically, as shown in FIGS. 4 and 6, the connecting member 14 is fixed to each vertical frame 11 by driving screws 31 through the left and right ends of the connecting member 14 from the space S side sandwiched by the pair of vertical frames 11, 11 toward the inner surface of the groove 16. In this way, instead of driving the screws 31 from the outside of the pair of vertical frames 11, 11 toward the connecting member 14, by driving the screws 31 from the space S side sandwiched by the pair of vertical frames 11, 11 toward the inner surface of the groove 16, after the construction structure A is arranged in the opening O and the pair of vertical frames 11, 11 are fixed to the columns 2, 2, the screws 31 can be pulled out. The connecting member 14 can be removed from the pair of vertical frames 11 by pulling out and cutting the screws 31. In the first embodiment, the left and right ends of the connecting member 14 are fixed to the pair of vertical frames 11 with the screws 31 as described above, so that the connecting member 14 is removably fixed to each vertical frame 11.

[0041] -Construction method of the two-sided frame- Next, the construction method of the two-sided frame 10 will be described. As described above, in the first embodiment, the two-sided frame 10 is constructed using the construction structure A in which the pair of vertical frames 11, 11 are connected by the connecting member 14.

[0042] First, the construction structure A is assembled (assembly step). Specifically, as shown in FIG. 4, the left and right ends of the connecting member 14 are inserted into the grooves 16, 16 for providing the stoppers 13 of the pair of vertical frames 11, 11 until the end faces contact the bottom surfaces of the grooves, and the screws 31 are driven through the left and right ends of the connecting member 14 from the space S side sandwiched by the pair of vertical frames 11, 11 toward the inner surface of the groove 16, thereby removably fixing the connecting member 14 to each vertical frame 11.

[0043] After the assembly step, as shown in FIG. 7A, the assembled construction structure A is arranged at a predetermined construction position in the opening O, and the pair of vertical frames 11, 11 of the construction structure A are fixed to the columns 2, 2 installed on both sides of the opening O. Specifically, spacers 4 are inserted between each vertical frame 11 and each column 2, and screws 41 are driven from the inner surface side of each vertical frame 11 toward the column 2, thereby fixing each vertical frame 11 to the corresponding column 2 via the spacer 4.

[0044] After the fixing work, as shown in FIG. 7B, the connecting member 14 is removed from the construction structure A fixed to the columns 2, 2 installed on both sides of the opening O (removing step). Specifically, the screws 31, 31 driven into the left and right end portions of the connecting member 14 are pulled out and removed from the pair of vertical frames 11, 11. In Embodiment 1, after pulling out the screws 31, 31, the connecting member 14 is cut and removed.

[0045] After the removing step, as shown in FIG. 7C, a doorstop 13 is provided on the pair of vertical frames 11, 11 (doorstop construction step). Specifically, an adhesive is applied into the grooves 16, 16 of the pair of vertical frames 11, 11, and the narrow portion 13b of the doorstop 13 is inserted and fixed.

[0046] Through the above steps, the two-sided frame 10 is constructed inside the opening O.

[0047] Note that the partition material 12 is attached to the pair of vertical frames 11, 11 after the construction of the wall base materials 3,..., 3. The partition material 12 is inserted with the end portion of the vertical plate portion 12a into the grooves 15 formed on the front and rear surfaces of the vertical frame 11, and after being arranged at a position where the end portion of the horizontal plate portion 12b abuts against the end portion of the wall W (the end portion of the wall base material 3), it is fixed to the vertical frame 11 with a nail-like member such as a pin nail.

[0048] - Effects of Embodiment 1 - In this Embodiment 1, in order to construct the good-looking two-sided frame 10 without an upper frame, a construction structure A is used in which a connecting member 14 that removably fixes at least the upper end portions to the pair of vertical frames 11, 11 that form the two-sided frame 10 is fixed. According to such a construction structure A, after fitting the construction structure A into the opening O extending from the floor surface Fs to the ceiling surface Cs formed in the indoor wall W and fixing the pair of vertical frames 11, 11, by simply removing the connecting member 14, it is possible to easily construct the good-looking two-sided frame 10 without an upper frame inside the opening O without performing complicated alignment.

[0049] Also, in the first embodiment, the connecting member 14 is detachably bridged across the groove 16 provided in the door stop 13 of the pair of vertical frames 11, 11. According to such a configuration, for example, even if screws (nail-like members) 31 are used to fix the connecting member 14, after the connecting member 14 is removed, the holes left by the screws (nail-like members) 31 are hidden by the door stop 13 and become invisible. Therefore, according to the first embodiment, the aesthetically pleasing two-sided frame 10 without an upper frame can be easily constructed in the opening O without impairing the design.

[0050] By the way, the construction structure A is fixed in the opening O by being fixed to the columns 2, 2 installed on both sides of the opening O. Therefore, in the construction structure A, if the connecting member 14 is fixed to each vertical frame 11 by driving a screw (nail-like member) 31 from the outside of the pair of vertical frames 11, 11 toward the end of the connecting member 14, the screw (nail-like member) 31 cannot be pulled out after the construction structure A is constructed in the opening O.

[0051] Therefore, in the first embodiment, the screw (nail-like member) 31 for fixing the connecting member 14 to each vertical frame 11 is driven so as to penetrate the connecting member 14 toward the inner surface of the door stop groove 16 into which the end of the connecting member 14 fits from the space S side sandwiched by the pair of vertical frames 11, 11. By driving the screw (nail-like member) 31 in such a direction, it becomes possible to pull out the screw (nail-like member) 31 after the construction structure A is fixed in the opening O, and it becomes possible to remove the connecting member 14.

[0052] Also, in the first embodiment, the upper and lower end portions of the pair of vertical frames 11, 11 are connected by two connecting members 14, 14 respectively, so that the pair of vertical frames 11, 11 can be easily and aesthetically constructed in the opening O while maintaining a parallel positional relationship.

[0053] In addition, in the construction method of the first embodiment, a construction structure A is used for the construction of the two-sided frame 10. After the construction structure A is arranged at a predetermined construction position within the opening O and a pair of vertical frames 11, 11 are fixed to the columns 2, 2 installed on both sides of the opening O, the connecting member 14 is removed from the construction structure A, so that only the pair of vertical frames 11, 11 that form the two-sided frame 10 are constructed within the opening O. According to such a construction method, a visually appealing two-sided frame 10 without an upper frame can be easily constructed within the opening O without performing complicated alignment as in the prior art.

[0054] Further, in the construction method of the first embodiment, after the connecting member 14 is removed, a door stop 13 is provided in the grooves 16, 16 of the pair of vertical frames 11, 11 across which the connecting member 14 was spanned. Therefore, for example, even if screws (nail-like members) 31 are used for fixing the connecting member 14, after the connecting member 14 is removed, the holes left by the screws (nail-like members) 31 are hidden by the door stop 13 and become invisible. Therefore, according to the construction method of the first embodiment, a visually appealing two-sided frame 10 without an upper frame can be easily constructed within the opening O without impairing the design.

[0055] 《Other Embodiments》 In the above-described first embodiment, in the construction structure A, the pair of vertical frames 11, 11 were connected by two connecting members 14, 14. However, the number of connecting members 14 is not limited to this. The number of connecting members 14 only needs to be able to connect at least the upper end portions of the pair of vertical frames 11, 11 with the connecting member 14, and may be one or three or more.

[0056] In addition, in the above-described first embodiment, the connecting member 14 was composed of a strip-shaped member, but it may be composed of a non-elongated rectangular plate-shaped member whose left and right end portions are inserted and fixed into the grooves 16, 16 of the pair of vertical frames 11, 11.

[0057] In the above-described Embodiment 1, in the construction structure A, the connecting member 14 was removably fixed to each vertical frame 11 using screws 31 (nail-like members). However, the means for removably fixing the connecting member 14 to each vertical frame 11 is not limited to the screws 31, and it may be fixed with nail-like members other than the screws 31, such as nails or pin nails.

[0058] Furthermore, the means for removably fixing the connecting member 14 to each vertical frame 11 may be other than nail-like members. For example, a dowel groove may be formed on the lower surfaces of the left and right ends of the connecting member 14, and the connecting member 14 may be removably fixed to each vertical frame 11 using a dowel. Also, engaging members may be embedded in the corresponding portions of the left and right ends of the connecting member 14 and a pair of vertical frames 11. After inserting the left and right ends of the connecting member 14 until they abut against the groove bottom surfaces of the grooves 16, 16 of the pair of vertical frames 11, 11, when the screws inside the engaging member on the connecting member 14 side are tightened, the connecting member 14 may be removably fixed to each vertical frame 11 using a knockdown fitting or the like in which the engaging member on the connecting member 14 side and the engaging member on the vertical frame 11 side engage. When using a dowel or a knockdown fitting, it is preferable to embed the dowel and the engaging member in the grooves 16, 16 of the vertical frame 11. This is because after removing the connecting member 14, by simply providing the door stop 13, the dowel holes and the embedding holes for the engaging members can be hidden by the door stop 13.

[0059] In the above-described Embodiment 1, the connecting member 14 was provided so as to be spanned between the groove bottom surfaces of the grooves 16 of the pair of vertical frames 11, 11. However, the connecting member 14 may be spanned between portions other than the grooves 16, 16 on the inner surfaces of the pair of vertical frames 11, 11 and be removably fixed to each vertical frame 11.

[0060] In the above-described Embodiment 1, one groove 16 into which two support legs constituting the support leg portion 13b are inserted for one door stop 13 is formed on the inner surface of each vertical frame 11. However, two grooves 16 may be formed so that the two support legs are inserted separately. In this case, for example, the connecting member 14 is placed in a state where the left and right end portions abut between the two grooves 16, 16 on the inner surface of each vertical frame 11, and the screw 31 (nail-like member) is inserted from the space S side sandwiched by the pair of vertical frames 11, 11 toward the two grooves 16, 16 and between the two grooves 16, 16 so as to penetrate the connecting member 14, and then it may be detachably fixed to each vertical frame 11.

[0061] In the above-described Embodiment 1, the door stop 13 is configured to have the main body portion 13a and the support leg portion 13b. However, the door stop 13 may have any configuration as long as it can serve as a door stop and hide the screw hole (nail hole) of the screw 31 (nail-like member) as described above. For example, the door stop 13 may be a hollow member extending in the vertical direction having a wide portion with a long width (length in the expected direction) and a narrow portion with a short width without having two support legs, and the cross section is formed in a convex shape, and the narrow portion is fixed to the vertical frame 11 with an adhesive or the like in a state of being inserted into the groove 16.

[0062] Also, the shape of the vertical frame 11 is not limited to the shape of Embodiment 1, and may be any shape. The vertical frame 11 may not have the groove 15 formed and may not be provided with the partition members 12, 12.

[0063] Also, the door stop 13 and the groove 16 are not limited to the shapes of Embodiment 1, and may be any shape.
