Description

[Technical Field]

[0001] The present invention relates to an opening / closing door, a door stop member, and a method for exposing a part of the tip surface of a panel member covered by the door stop member. [Background technology]

[0002] 2. Description of the Related Art Sliding doors or other doors with doorstops attached to their door edges are widely used at entrances and exits to the interior and exterior of buildings or to partitioned spaces within buildings. The door stop member is integrally molded from a long, hollow rubber member that is easily elastically deformed and restored, and is attached across the entire vertical edge of the door-front end face of the panel member that constitutes the main part of the sliding door. Some sliding doors are suspended from an upper frame that supports the door, allowing them to move in the opening and closing directions. In such suspended sliding doors, a recessed suspension member that supports a suspension roller is detachably attached to the upper end of the door leading side of the panel member in a direction perpendicular to the end face of the panel member (i.e., horizontally). With this configuration, when maintenance or the like is desired on the recessed type hanging member including the hanging roller, the recessed type hanging member is removed and, after the maintenance is completed, is fitted into the fitting portion of the panel member. Even in the case of a sliding door having a recessed-type suspension member as described above, the conventional door stop member integrally covers the entire door-leading end face of the panel member, including the recessed-type suspension member. Summary of the Invention [Problem to be solved by the invention]

[0003] With conventional sliding doors, when it is necessary to remove the door stop, such as when attaching or detaching a recessed-type hanging member, the sliding door must be removed from the upper and lower frames. Particularly when the sliding door is a hanging type, it is necessary to release the hanging roller from the sliding door and remove the hanging roller from the hanging rail, which is a very cumbersome process. Therefore, the present invention provides a door that can be opened and closed easily, with a portion of the door-leading end surface of the panel member easily exposed. [Means for solving the problem]

[0004] The opening and closing door of the present invention comprises a panel member that opens and closes an opening in a side wall of a building, and a door stop member provided on the tip surface of the panel member, the door stop member being configured with a plurality of divided bodies, each of which has a separate divided body that can be attached and detached in a direction away from the tip surface. According to this configuration, by providing the separation divided body, it is possible to expose a part of the tip end surface of the panel member.

[0005] The plurality of partitions of the opening / closing door of the present invention may include a sliding partition attached to be freely movable up and down along the tip surface of the panel member, and the sliding partition may be provided adjacent to and immediately above the separating partition. According to this configuration, the separation partition is provided at a location other than the location where the tip surface of the panel member is desired to be exposed, and the tip surface can be easily exposed by removing the separation partition and moving the sliding partition.

[0006] The separated divided body of the opening and closing door of the present invention may be configured to include the lowermost end of the door stop member. According to this configuration, the separation divided body that is detachably attached to the tip end surface of the panel member can be formed in a location that is less noticeable overall.

[0007] The opening and closing door of the present invention may be provided with a recessed hanging member at the upper end of the panel member on the door edge side, which is connected to a hanging roller that moves the panel member horizontally while it is suspended, and the separation partition body may be formed to be larger in the vertical direction than the vertical dimension of the recessed hanging member. This configuration makes it easy to attach and detach the recessed type hanging member.

[0008] A base portion having a threaded hole into which a screw can be screwed is fixed to the door-front end face of the panel member of the opening and closing door of the present invention, and the separation divided body has a through hole through which a screw can be inserted and screwed into the threaded hole formed in the base portion, and the screw passes through and screws into the through hole and the threaded hole, thereby fixing the separation divided body to the panel member in a removably attachable manner. According to this configuration, the separated divided body can be stably and firmly attached to the tip end surface of the panel member, and the attachment and detachment can be easily performed.

[0009] The through hole of the opening and closing door of the present invention may be provided with a cover member that allows the through hole to be opened and closed. This configuration can prevent foreign objects from entering the interior of the door stop member through the through-hole, or prevent mischief such as inserting foreign objects into the through-hole.

[0010] The door stop member of the present invention has a separation divided body provided on any one of the above-described opening and closing doors.

[0011] A method for exposing a portion of the tip surface of a panel member covered by a door stop member constituting an opening / closing door of the present invention includes the steps of using any of the opening / closing doors described above, removing a separation partition from the panel member, and, after removing the separation partition, moving the sliding partition up and down along the end surface. [Effects of the Invention]

[0012] The opening and closing door of the present invention has the advantage that the door stop member can be attached and detached to easily expose a part of the tip surface of the panel member. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a door and a method for attaching and detaching a door stop member of the door according to the present invention will be described below with reference to the drawings.

[0015] As shown in Figure 1, the sliding door (opening and closing door) 1 of the present invention is suspended from a middle horizontal frame (hereinafter referred to as the "middle horizontal frame") 3 of an opening W1 formed in a side wall W of a building, and moves between vertical frames 2, 2 fixed to both the left and right ends of the opening to open and close the opening W1.

[0016] In this embodiment, a pair of vertical frames 2, 2 on the left and right, an upper horizontal frame 4, and a middle horizontal frame 3 are provided in an opening W1 in a side wall W of a building, and shoji windows 5, 5 and the like are installed between the upper horizontal frame 4 and the middle horizontal frame 3. Sliding doors 1, 1 are installed between the vertical frames 2, 2, the middle horizontal frame 3, and the floor F (or a lower horizontal frame without a transom in some cases). Note that in openings where there are no shoji windows 5, 5, the sliding doors 1 are hung directly on the upper frame 4.

[0017] The vertical frame 2 is a crosspiece member having a length from the upper end to the lower end of the opening W1 of the frame, and is fixed to the left and right inner end faces of the opening W1 with screws or the like. The upper horizontal frame 4 is attached so as to face the upper surface of the opening W1, for example by fixing both ends to the upper ends of the vertical frame 2.

[0018] As shown in FIG. 2, upper and lower shoji rails 7a and 7b are fixed to the lower surface of the upper horizontal frame 4 and the upper surface of the middle horizontal frame 3, respectively, and shoji windows 5 and 5 are fitted between the upper and lower shoji rails 7a and 7b.

[0019] The central horizontal frame 3 is formed in a roughly rectangular C-shape when viewed in the longitudinal direction (i.e., the direction into the paper of FIG. 2). The central horizontal frame 3 is made of a material such as a steel plate having a predetermined thickness. Hanger rails 8, 8 for suspending the sliding door are fixed to the central horizontal frame 3 using bolts or the like. The sliding doors 3, 3 shown in FIG. 1 are hung from the hanger rails 8, 8 via hanger rollers 9, 9 so as to be movable in the longitudinal direction of the rails.

[0020] As shown in Fig. 3, the sliding door 1 comprises a panel member 10 that covers almost half of the left and right direction of the opening, and a door stop member 11 attached to the door leading end of the panel member 10. For the sake of convenience in explaining the present invention, Fig. 3 is a diagram in which the door stop member 11 and the panel member 10 of the sliding door 1 are partially broken away to expose the inside and to clearly show the fixation of a separation divided body 21, which will be described later (the same applies to Figs. 6 to 9). 1 or 2, the panel member 10 is formed in the shape of a substantially rectangular plate having a certain thickness. Specifically, the panel member 10 is a plate member in which two thin rectangular surface materials 12, 12 are arranged parallel to each other with their plate surfaces facing each other, and the space between them is filled with, for example, a paper core to form a filling portion 13.

[0021] As shown in Figure 4, the leading end portions 12a of the two surface materials 12, 12 are bent in a direction to cover the leading end surface (leading end surface) 10a of the door. Each leading end portion 12a is bent so as to cover the end surface by several millimeters. The bent tip end 12a serves as a locking portion that locks the door stop member 11. The locking portion is provided continuously across the upper and lower ends of the panel member 10. Between the tip ends 12a, 12a, a locking portion of the door stop member 11 (described later) is provided. Mounting part 22 A certain interval is provided so that the holding portion 25 of the holder 25 protrudes from the inside.

[0022] As shown in FIG. 3, the panel member 10 is provided with a fixing portion 10k at the upper corner on the door leading side, to which a recessed type hanging member 14 can be fixed. The recessed type hanging member 14 is configured so that it can be detachably engaged with the rectangular cutout portion at the upper corner of the panel member 10 by pushing it horizontally toward the door end.

[0023] As shown in Figure 4, U-shaped reinforcing members 15 that form approximately rectangular recesses are attached to the top, bottom, left, and right ends of the panel member 10, excluding the portions where the recessed-type hanging members 14 are attached, along the respective tip surfaces 10a, etc. The reinforcing member 15 is a long rod-like member having a U-shaped (or substantially U-shaped) cross section perpendicular to the longitudinal direction. The reinforcing members 15 are fixed to the upper, lower, left and right ends of the panel member 10 so that the recesses are open to the outside.

[0024] As shown in FIG. 3, a base portion 16 made by bending a rectangular steel plate into a so-called hat shape is fixed to a reinforcing member 15 at the lower part of the door-front end surface 10a of the panel member 10. As shown in Figure 3 or Figure 5, the base portion 16 has a flange portion 16a formed at both longitudinal ends of the strip shape and abutting against the reinforcing member 15 to fix it, and a protrusion portion 16b formed in an approximately rectangular U-shape inside the flange portion 16a.

[0025] The protruding portion 16b has female screw holes 16h formed at intervals in the longitudinal direction, into which screws are screwed. The two flanges 16a are firmly fixed to the reinforcing member 15 so as to be aligned longitudinally with a gap between them. The fixing method for the flanges 16a is not important as long as they are fixed so as not to easily come off the reinforcing member 15, but in this embodiment, they are fixed by welding.

[0026] As shown in FIG. 3, a door stop member 11 is attached to the door-front end surface 10a of the panel member 10. The door stop member 11 is composed of a sliding partition 20 that can move up and down along the door-leading end face 10a of the panel member 10, and a separation partition 21 that is detachably attached in a direction away from the door-leading end face 10a (i.e., in an approximately vertical direction).

[0027] As shown in Figure 4, the sliding division body 20 has an attachment part 22 that is attached to the tip end 12a of the surface material 12 of the panel member 10 so as to be freely movable up and down, and a buffer part 23 that is fixed to the attachment part 22 and protrudes from the surface materials 12, 12 to cushion the door contact. The mounting portion 22 has a clamped portion 24 that is formed to be approximately convex in a cross-sectional view perpendicular to the longitudinal direction and is sandwiched between the surface materials 12, 12, and a holding portion 25 that is provided at the tip of the clamped portion 24 and engages and holds the buffer portion 23.

[0028] The clamped portion 24 has a locking portion 24a that is pressed against the opposing inner surface 15k of the tip of the reinforcing member 15, and a constricted portion 24b that extends in a J-shape and an inverted J-shape from the tip of the locking portion 24a toward the center thereof. The holding portion 25 has a protruding portion 26 that extends from the tip of the constricted portion 24b to close the space between the tip ends 12, 12 of the surface material 12 and further extends in a direction away from each other, and a locking recess 26a provided at the tip of the protruding portion 26.

[0029] The protruding portion 26 extends linearly. The tip portion 12a of the surface material 12 and the tip of the reinforcing member 15 are fitted into a groove formed between the constricted portion 24b and the protruding portion 26, and can be fixed thereto. The locked recesses 26a are formed facing in opposite directions so as to open in the direction in which the protruding portion 26 extends. The attachment portion 22 is formed to be line-symmetrical in a cross section perpendicular to the longitudinal direction, and extends in the longitudinal direction (the depth direction of the paper in FIG. 4).

[0030] The buffer portion 23 is formed in a generally convex shape with an opening on the base end side in a cross section perpendicular to the longitudinal direction. The buffer portion 23 is formed hollow with a generally constant thickness. The shape of the buffer portion 23 is not particularly limited as long as it can absorb the pressure or impact caused by the door edge of the sliding door 1. A protruding strip 23 a that fits tightly into the locking recess 26 a of the mounting portion 22 is formed on the inner surface of the base end of the buffer portion 23 . With the above-described configuration, the sliding division body 20 is configured to be able to move up and down along the door-front side end surface 10a of the panel member 10 while being held by the surface members 12, 12 and the reinforcing member 15.

[0031] As shown in Figure 6, the separation partition 21 is formed to have the same shape as the sliding partition 20 in a cross-sectional view perpendicular to the longitudinal direction, except that fastener holes (through holes) 30a, 30b are formed that penetrate toward the panel member 10. The fastener holes 30a, 30b are formed in the buffer portion 23 and the protruding portion 26, respectively. The fastener hole 30 formed in the buffer portion 23 is referred to as the first hole 30a, and the fastener hole 30 formed in the protruding portion 26 is referred to as the second hole 30b. The first hole 30a is formed with a diameter that allows the head of the screw 35 to pass through. The second hole 30b formed in the protruding portion 26 is formed with a diameter dimension that allows the body of the screw 35 to pass through but not the head.

[0032] The first hole 30a and the second hole 30b are formed in the center of the width direction when viewing the separation partition 21 in a direction viewing the end face 10a of the panel member 10 from the front, and are formed so as to face the female screw hole 16h formed in the base portion 16 and to be concentric with the female screw hole 16h. The separated divided body 21 is fixed to the base portion 16 by a screw 35 that passes through the first hole 30a, the second hole 30b, and the female screw hole 16h of the base portion 16.

[0033] The separated divided body 21 is formed to be line-symmetrical in a cross section perpendicular to the longitudinal direction, and extends in the longitudinal direction. The separated divided body 21 covers the lower part of the panel member 10 including the lowest end, with a length D2 that is the same as or slightly larger than the vertical length D1 of the recessed type hanging member 14 shown in FIG.

[0034] The sliding division body 20 is adjacent to and above the separation division body 21, and covers the entire end face 10a of the panel member 10 other than the end face 10a covered by the separation division body 21. The door stop member 11, i.e., the sliding divided body 20 and the separation divided body 21, are formed from an elastic material that can absorb the impact when the door edge hits an object or a person when the sliding door 1 moves (especially when closing). Specifically, rubber, elastomer, etc. are preferably used as the material for the door stop member 11.

[0035] Next, a method of using the sliding door 1 of the present invention, as well as its functions and effects, will be described. To expose a portion of the tip surface 10a of the panel member 10 using the door stop member 11 of the hanging sliding door 1 shown in Figure 2, remove the screws 35 that have been inserted and tightened through the fastener holes 30a, 30b of the separation partition 21 and the female screw hole 16h of the base portion 16, as shown in Figure 7.

[0036] The separation divided body 21 is removed from the door-front end of the panel member 10, and a movement space for the sliding divided body 20 is formed below the panel member 10 where the separation divided body 21 was attached. As shown in FIG. 8, the sliding division body 20 is moved downward along the door-front end surface 10a of the panel member 10 to expose the recessed type hanging member 14.

[0037] This allows the recessed type hanging member 14 to be removed and moved horizontally, so the recessed type hanging member 14 can be removed, maintenance can be performed as needed, and then the member can be reattached to the panel member 10 in the specified position. After the recessed type hanging member 14 is attached, the door stop member 11 is attached to cover the entire end surface 10a of the panel member 10 by following the above procedure in reverse.

[0038] As described above, according to the sliding door 1 of the present invention, the separation divided body 21 can be easily attached and detached without damaging the door stop member 11 by forcibly peeling it off from the panel member 10, or without the trouble of removing the sliding door 1. Therefore, the sliding door 1 has the effect that, particularly when the panel member 10 has a recessed-type hanging member 14, the door stop member 11 can be removed very easily to easily perform maintenance on the panel member 10 or a part thereof.

[0039] In the above embodiment, the separation divided body 21 is provided at the lower part including the lowest part of the sliding door 1, but the position where the separation divided body 21 is formed is not limited to the above part. In other words, the separation divided body 21 only needs to have the vertical dimension of the part of the panel member 11 such as the recessed type hanging member 14 that is desired to be exposed, and be provided directly above or below the part that is desired to be exposed.

[0040] For example, as shown in Fig. 9, when the end face 10a of the panel member 10 to be exposed is in a region S in the middle in the longitudinal direction (i.e., the up-down direction), the separation division 21 may be formed with dimensions equal to or slightly larger than the longitudinal dimension of the region S, and provided immediately above or below the region S. In this case, the sliding division 20 covering the region S may be formed as a first sliding division 20A formed with dimensions equal to the longitudinal dimension of the separation division 21, and may be formed to be slidable separately from the portion of the sliding division 20 adjacent thereto (referred to as a "second sliding division 20B").

[0041] If the area directly above or below the region S does not have the length required for the separation divided body 21, the separation divided body 21 is provided on the side that has that length. Sliding divided bodies 20 are attached to all areas other than the area where the separation divided body 21 is provided.

[0042] Even with the door stop member 11 of this type, the same functions and effects as those of the above-described embodiment can be obtained by removing the separation partition 21 and moving the first sliding partition 20A upward or downward.

[0043] Furthermore, the first hole 30a formed in the separation divided body 21 does not necessarily have to be formed to a size equal to or slightly larger than the diameter of the head of the screw, as long as a tool such as a screwdriver can be inserted therein to screw in the screw. The sliding door 1 may also have a cover member that closes the first hole 30a.

[0044] Furthermore, the present invention can be widely applied not only to sliding doors 1 consisting essentially of a single panel, such as those in the above-described embodiments and their variations, but also to opening and closing doors 1 of a type in which the portion including the door stop member 11 and the door leading end surface 10a can move along the horizontal frame of the opening W when opening and closing. Specifically, for example, the present invention can be suitably applied to the door edge of a so-called folding door, in which the opening door 1 is mainly composed of two adjacent panels and can open and close the opening W by folding the two panels at the center in the width direction. As another example, the present invention can be applied to the door edge of a so-called accordion-type opening door 1, which is mainly composed of multiple panels or flexible sheet members and can be opened and closed by zigzag folding or expanding and contracting bellows.
