DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, the embodiment of the sliding door and the installation method of the sliding door according to the present invention will be described in detail with reference to the attached drawings. First, [I] the basic concept of the embodiment will be described, then [II] the specific contents of the embodiment will be described, and finally, [III] modified examples of the embodiment will be described. However, the present invention is not limited to the embodiment.

[0024] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment generally relates to a sliding door including a frame body provided at an opening of a building, the frame body being located above the opening and including a hollow upper frame member with an open lower end, a plurality of opening / closing bodies that slide within the frame body to open and close the opening, and movement assisting means that are provided at positions corresponding to each opening / closing body within the upper frame member and that assist the sliding movement of each opening / closing body while suspending each opening / closing body, and a method for installing the sliding door.

[0025] Here, the term "building" refers to any specific structure or type, but is a concept that includes, for example, public facilities, commercial facilities, detached houses, collective housing such as apartments and condominiums, etc. Also, an "opening in a building" is an opening formed in a part of the framework of a building (for example, a wall, etc.) for installing an entrance / exit.

[0026] Moreover, the term "sliding door" refers to a structure installed at an opening, which is for restricting or limiting entry and exit through the opening. The opening and closing structure of the sliding door is arbitrary, and includes, for example, a single-opening sliding door having multiple opening and closing bodies that move open and close in unison, and a single-opening sliding door having multiple opening and closing bodies that move open and close without being interlocked.

[0027] In the following embodiment, a sliding door will be described as a single-opening sliding door provided on the wall on the aisle side of a specific room in a building such as a public facility, and having multiple opening and closing bodies that open and close in conjunction with each other.

[0028] [II] Specific Contents of the Embodiments Next, the specific contents of the embodiment will be described.

[0029] (composition) First, the configuration of the sliding door according to the embodiment will be described. In the following description, the X direction in Fig. 1 is referred to as the left-right direction of the sliding door (-X direction is the left direction of the sliding door, and +X direction is the right direction of the sliding door), the Y direction in Fig. 2 is referred to as the front-rear direction of the sliding door (+Y direction is the front direction of the sliding door (toward the outside of the room) and -Y direction is the rear direction of the sliding door (toward the inside of the room)), and the Z direction in Fig. 1 is referred to as the up-down direction of the sliding door (+Z direction is the up direction of the sliding door, and -Z direction is the down direction of the sliding door).

[0030] As shown in FIG. 1, the sliding door 1 is provided in an opening 3 of a frame 2 (specifically, a wall) of a room (building), and is generally provided with a frame 10, a door pocket panel 14, a door-leading side opening / closing body 20, a door-tailing side opening / closing body 30, a door-leading side movement assisting part 40, a door-tailing side movement assisting part 50, a door-leading side vibration stopping part 60, and a door-tailing side vibration stopping part 70. The door-leading side opening / closing body 20 and the door-tailing side opening / closing body 30 are slid in tandem in the left-right direction (horizontal direction) inside the frame 10, thereby opening and closing the opening 3 with the door-leading side opening / closing body 20 and the door-tailing side opening / closing body 30. However, the configuration of the sliding door 1 that is not specifically mentioned is the same as that of the conventional one, and the description thereof will be omitted. In addition, the above-mentioned "door-leading side opening / closing body 20" and "door-tailing side opening / closing body 30" correspond to "multiple opening / closing bodies" in the claims.

[0031] Here, the "open / closed state of the leading-door side opening / closing body 20 and the trailing-door side opening / closing body 30" is a concept that includes, for example, a "fully closed state", a "fully open state", and a "half-open state".

[0032] Among these, the "fully closed state" is a state in which the opening 3 is fully closed by the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 as shown in FIG. 3(a), and in the embodiment, the positions of the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 in the fully closed state are referred to as the "fully closed position". Also, the "fully open state" is a state in which the opening 3 is fully opened by the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 as shown in FIG. 3(b), and in the embodiment, the positions of the opening / closing body in the fully open state are referred to as the "fully open position". Also, the "half-open state" is a state in which the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 are positioned between the fully closed position and the fully open position, and the positions of the opening / closing body in the half-open state are referred to as the "half-open position".

[0033] The method of mounting (or connecting) the various components constituting the sliding door 1 is arbitrary. For example, a method of mounting (or connecting) the component on the mounting side to the component on the mating side through mounting holes (e.g., rivet holes, screw holes, screw holes, etc.) formed in the component on the mounting side or the component on the mating side using fasteners (e.g., rivets, mounting screws, screws, etc.), welding, adhesives, double-sided tape, etc. is used.

[0059] (Configuration - Door end opening / closing body - Door end opening / closing body frame) Returning to Fig. 2, the trailing edge side opening / closing body frame 31 is mainly responsible for the rigidity of the trailing edge side opening / closing body 30. This trailing edge side opening / closing body frame 31 is constructed substantially similarly to the leading edge side opening / closing body frame 21, and as shown in Fig. 2, is composed of a pair of vertical force bones (not shown) on the left and right and a pair of upper and lower horizontal force bones 31a.

[0060] (Composition - door bottom side opening / closing body - door bottom outdoor surface material, door bottom indoor surface material) The trailing edge exterior surface material 32 and the trailing edge interior surface material 33 are intended to cover the trailing edge side opening / closing body frame 31 and the trailing edge side core material 34, and are arranged to cover the trailing edge side opening / closing body frame 31 and the trailing edge side core material 34, as shown in Figure 2.

[0061] (Configuration - Door end opening and closing body - Door end core material) The trailing edge side core material 34 is filled inside the trailing edge side opening / closing body 30, and is filled in the space surrounded by the trailing edge side opening / closing body frame 31, the trailing edge exterior surface material 32, and the trailing edge interior surface material 33, as shown in Figure 2.

[0062] (Configuration - Door end side opening and closing body - Door end side door stop part) Returning to FIG. 1, the trailing edge side door stop portion 35 is intended to cushion the impact when an object passing through is pinched between the trailing edge side end of the trailing edge side opening / closing body 30 and the trailing edge side frame material 12, and is provided over almost the entire trailing edge side end of the trailing edge side opening / closing body 30, as shown in FIG. 1 and FIG. 3.

[0063] (Configuration: Door end movement support section) Returning to FIG. 1, the configuration of the door-end side movement assisting portion 40 will now be described.

[0064] The door-end side movement assisting part 40 is a movement assisting means that assists the sliding movement of the door-end side opening / closing body 20 while suspending the door-end side opening / closing body 20. As shown in Figs. 1 and 2, the door-end side movement assisting part 40 is provided in a position corresponding to the door-end side opening / closing body 20 in the upper frame member 13 (in Fig. 2, it is a position between the upper frame member 13 and the door-end side opening / closing body 20, and is a position on the outside of the room in the upper frame member 13), and includes a door-end side rail part 41, a door-end side wheel part 42, a door-end side connection part 43, an automatic closing part 44, a part for maintaining a fully open state (not shown), a first braking part 45, and a second braking part 46.

[0065] (Configuration - Door end side movement support part - Door end side rail part) Returning to Fig. 1, the leading-side rail section 41 is a rail means for sliding the leading-side roller section 42 in the left-right direction. The leading-side rail section 41 is configured, for example, using a known long rail member for sliding doors (as an example, an aluminum rail member) or the like, and is formed so that the left-right length of the leading-side rail section 41 is longer than the length of the movement range of the leading-side roller section 42.

[0066] Furthermore, as shown in Figures 1 and 2, the longitudinal direction of this door-end side rail portion 41 is arranged along the left-right direction within the upper frame material 13, and is fixed by a fastener or the like to the first connecting member 13h attached to the interior facing surface piece 13b.

[0067] (Configuration - Door end side movement support part - Door end side door roller part) Returning to Fig. 1, the leading-side roller section 42 is a moving means for enabling the leading-side opening / closing body 20 to slide. This leading-side roller section 42 is configured, for example, using a known roller for a sliding door (the same applies to other rollers), and as shown in Figs. 1 and 2, a plurality of rollers are provided on the rail surface of the leading-side rail section 41 at intervals within the upper frame member 13 (two rollers are provided in Fig. 1).

[0068] In the following, where necessary, the leading side roller section 42a located on the leading side will be referred to as the "first leading side roller section 42a," and the leading side roller section 42b located on the trailing side will be referred to as the "second leading side roller section 42b."

[0069] (Configuration - Door end side movement support part - Door end side connection part) Returning to Fig. 1, the door-end side connection part 43 is a door-end side connection means for connecting the door-end side roller part 42 and the door-end side opening / closing body 20. This door-end side connection part 43 is configured, for example, using a known connection member for sliding doors (for example, a steel connection member with an L-shaped side shape), and specifically, as shown in Figs. 1 and 2, includes a first door-end side piece 43a connected to the door-end side roller part 42, a second door-end side piece 43b connected to the door-end side opening / closing body 20, and a third door-end side piece 43c connecting the first door-end side piece 43a and the second door-end side piece 43b.

[0070] Furthermore, as shown in Figures 1 and 2, this door-leading side connection portion 43 is provided within the upper frame material 13 at a position corresponding to each door-leading side roller portion 42, and is connected to the corresponding door-leading side roller portion 42 via a rotating shaft material (not shown), and is also connected to the door-leading side opening / closing body 20 by a fixing device or the like.

[0071] With this type of door-leading side connection part 43, the door-leading side opening / closing body 20 can be slid while being suspended from the door-leading side rail part 41 via the door-leading side wheel part 42.

[0072] In the following, as necessary, the door-end side connection part 43d located on the door-end side will be referred to as the "first door-end side connection part 43d", and the door-end side connection part 43e located on the door-end side will be referred to as the "second door-end side connection part 43e".

[0073] (Configuration - Door end movement support part - Automatic closing part) Returning to Fig. 1, the automatic closing section 44 is an automatic closing means for automatically closing the leading-door opening / closing body 20 and trailing-door opening / closing body 30. This automatic closing section 44 is configured, for example, using a known automatic closing device for sliding doors (as an example, an automatic closing device having a winding section (not shown) that winds out and winds up the wire 43h), and is provided in the upper frame material 13 at a position near the first leading-door connecting section 43d as shown in Figs. 1 and 2.

[0074] Specifically, it is fixed to the first door end connection part 43d by a fixture or the like, and is connected via a wire 43h to a wire connection part 43g (for example, a known connection metal fitting or the like) provided on a second connecting member 13i attached to the indoor side facing surface piece 13b. Note that this "second connecting member 13i" corresponds to a part of the components of "one facing surface" in the claims.

[0075] In addition, the specific operation of the automatic closing unit 44 is arbitrary, but for example, when an operator performs an opening operation to switch the open / closed state of the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 from a fully closed state to a fully open state (or a half-open state) via the gripping unit 25, the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 are moved to open. Then, accompanying this opening movement, the wire 43h is unwound from the winding unit of the automatic closing unit 44, and the stored force is stored in the winding unit by the opening operation. After that, when the operator releases the gripping unit 25, the wire 43h is wound up by the stored force in the winding unit, and the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 are automatically moved to close in conjunction with each other.

[0076] (Configuration - Door end movement support unit - Fully open state maintenance unit) Returning to Fig. 1, the fully open state maintaining part is a means for maintaining the fully open state. As shown in Figs. 1 and 2, this fully open state maintaining part is provided in the upper frame material 13, and is configured using, for example, a known fully open stop device for a sliding door.

[0077] Specifically, it comprises an interlocking portion provided on the first door end side connection portion 43d or the second door end side connection portion 43e, and an interlocking portion provided on the indoor facing surface piece 13b or the second connecting member 13i, which is capable of interlocking with the interlocking portion (both not shown).

[0078] In addition, the specific operation of the fully open state maintaining unit is arbitrary, but for example, when the opening and closing state of the leading edge side opening and closing body 20 and the trailing edge side opening and closing body 30 is switched from the fully closed state (or half-open state) to the fully open state by the operator via the gripping unit 25, the corresponding locked parts are locked by the locking parts. In this case, the leading edge side opening and closing body 20 and the trailing edge side opening and closing body 30 move in a linked manner to close by the automatic closing unit 44, but since the locking force between the locked parts and the locking parts is greater than the accumulated force of the winding part, the locking between the locked parts and the locking parts is maintained, and the fully open state is maintained. In addition, when the operator performs a closing operation to switch the opening and closing state of the leading edge side opening and closing body 20 and the trailing edge side opening and closing body 30 from the fully open state to the fully open state (or half-open state) via the gripping unit 25 in the fully open state, the locking between the locked parts and the locking parts is released, and the leading edge side opening and closing body 20 and the trailing edge side opening and closing body 30 move in a linked manner to close.

[0079] (Configuration: Door end side movement support part - First braking part, second braking part) Returning to Fig. 1, the first braking portion 45 and the second braking portion 46 are braking means for braking the opening and closing movement of the door-end side opening / closing body 20. The first braking portion 45 and the second braking portion 46 are configured using, for example, a known braking device for a sliding door, and are provided at a distance from each other within the upper frame member 13 as shown in Fig. 1.

[0080] In addition, the specific operation of the first braking unit 45 and the second braking unit 46 is arbitrary, but for example, when the opening and closing state of the leading end side opening and closing body 20 and the trailing end side opening and closing body 30 is switched from a fully open state (or a half-open state) to a fully closed state, the first braking unit 45 reduces the speed of the closing movement of the leading end side opening and closing body 20 compared to the speed of the closing movement before the switching, so that the impact of the leading end side opening and closing body 20 contacting the leading end side frame material 11 is mitigated. In addition, when the opening and closing state of the leading end side opening and closing body 20 and the trailing end side opening and closing body 30 is switched from a fully closed state (or a half-open state) to a fully open state, the second braking unit 46 can reduce the speed of the opening movement of the leading end side opening and closing body 20 compared to the speed of the opening movement before the switching.

[0081] (Configuration: Door end side movement support part) Next, the configuration of the trailing edge side movement assisting portion 50 will be described.

[0082] The trailing edge side movement assisting part 50 is a movement assisting means that assists the sliding movement of the trailing edge side opening / closing body 30 while suspending the trailing edge side opening / closing body 30. As shown in Figures 1 and 2, this trailing edge side movement assisting part 50 is provided in a position corresponding to the trailing edge side opening / closing body 30 in the upper frame member 13 (in Figure 2, it is a position between the upper frame member 13 and the trailing edge side opening / closing body 30, and is a position on the indoor side of the room in the upper frame member 13), and includes a trailing edge side rail part 51, a trailing edge side wheel part 52, a trailing edge side connection part 53, and an interlocking part 54.

[0083] (Configuration - Trailing edge side movement support part - Trailing edge side rail part) Returning to Fig. 1, the trailing edge side rail portion 51 is a rail means for sliding the trailing edge side roller portion 52 in the left-right direction. The trailing edge side rail portion 51 is configured using, for example, a known long rail member for a sliding door (as an example, an aluminum rail member) and is formed so that the left-right length of the trailing edge side rail portion 51 is longer than the length of the movement range of the trailing edge side roller portion 52.

[0084] 1 and 2, the trailing edge rail portion 51 is provided below the leading edge rail portion 41 within the upper frame member 13. Specifically, on the trailing edge side within the upper frame member 13, the longitudinal direction of the trailing edge rail portion 51 is provided along the left-right direction, and the trailing edge rail portion 51 is fixed by a fastener or the like to the second connecting member 13i attached to the interior facing surface piece 13b.

[0085] (Configuration - Trailing side movement support part - Trailing side wheel part) Returning to Fig. 1, the trailing edge side roller section 52 is a moving means for enabling sliding movement of the trailing edge side opening / closing body 30. As shown in Figs. 1 and 2, a plurality of trailing edge side roller sections 52 are provided on the rail surface of the trailing edge side rail section 51 at intervals within the upper frame member 13 (two are provided in Fig. 1).

[0086] (Configuration - End-of-door movement support part - End-of-door connection part) 1, the trailing edge side connection part 53 is a trailing edge side connection means for connecting the trailing edge side roller part 52 and the trailing edge side opening / closing body 30. The trailing edge side connection part 53 is configured using, for example, a known connecting member for sliding doors (as an example, a steel connecting member having an L-shaped side shape), and specifically, as shown in Figs. 1 and 2, includes a first trailing edge side piece 53a connected to the trailing edge side roller part 52 and a second trailing edge side piece 53b connected to the trailing edge side opening / closing body 30.

[0087] As shown in Figures 1 and 2, this trailing edge side connection portion 53 is provided within the upper frame material 13 at a position corresponding to each trailing edge side roller portion 52, and is connected to the corresponding trailing edge side roller portion 52 via a rotating shaft material (not shown), and is also connected to the trailing edge side opening / closing body 30 by a fixing device or the like.

[0088] With this trailing edge side connection portion 53 , the trailing edge side opening / closing body 30 can be slid while being suspended from the trailing edge side rail portion 51 via the trailing edge side roller portion 52 .

[0089] (Configuration - Door end side movement support part - Interlocking part) Returning to Fig. 1, the interlocking portion 54 is an interlocking means for interlocking the leading-side opening / closing body 20 and the trailing-side opening / closing body 30 to open and close. The interlocking portion 54 is configured, for example, using a known interlocking unit for sliding doors (as an example, an interlocking unit having a pulley 54a), and is provided in the upper frame member 13 at a position adjacent to each trailing-side wheel portion 52, as shown in Figs. 1 and 2.

[0090] (Configuration: Door end side stopper) Returning to Fig. 1, the door-end side vibration-stopping portion 60 is a door-end side vibration-stopping means for suppressing vibration in the prospective direction of the door-end side opening / closing body 20. As shown in Figs. 1 and 2, the door-end side vibration-stopping portion 60 is provided below the door-end side opening / closing body 20, and includes a door-end side vibration-stopping rail portion 61 (e.g., a known rail member) provided over substantially the entire length of the lower end of the door-end side opening / closing body 20, a door-end side vibration-stopping roller portion 62 (e.g., a known roller member) provided within the door-end side vibration-stopping rail portion 61, the door-end side vibration-stopping roller portion 62 arranged so as to be able to abut against the visible surface of the door-end side vibration-stopping rail portion 61, and a door-end side vibration-stopping support portion 63 connected to the door-end side vibration-stopping roller portion 62 and the door-end side opening / closing body 30, and supporting the door-end side vibration-stopping roller portion 62.

[0091] (Configuration: Door end side vibration stopper) Returning to Fig. 1, the trailing edge side anti-vibration part 70 is a trailing edge side anti-vibration means for suppressing the vibration of the trailing edge side opening / closing body 30 in the prospective direction. As shown in Figs. 1 and 2, the trailing edge side anti-vibration part 70 is provided below the trailing edge side opening / closing body 30, and includes a trailing edge side anti-vibration rail part 71 (for example, a known rail member) provided over substantially the entire length of the lower end of the trailing edge side opening / closing body 30, and a trailing edge side anti-vibration roller part 72 provided within the trailing edge side anti-vibration rail part 71 and fixed to the floor surface 4 by a fixture or the like, and arranged so as to be able to abut against the prospective surface of the trailing edge side anti-vibration rail part 71.

[0092] (Configuration-damage avoidance structure) Returning to FIG. 1, next, the damage avoidance structure of the door-end side opening / closing body 20 will be described.

[0093] The sliding door 1 is provided with a damage avoidance structure for avoiding damage to the door-end opening / closing body 20 caused by contact between the door-end opening / closing body 20 and the upper frame material 13 when an external force acts on the door-end opening / closing body 20 from the forward direction, and the features of this damage avoidance structure are as follows in the embodiment. Note that "external force" refers to, for example, natural forces such as wind, and non-natural forces such as people and objects.

[0094] (Configuration - Damage avoidance structure - First feature) First, regarding a first feature of the damage avoidance structure, as shown in FIGS. 1 to 3, the damage avoidance structure includes a first contact prevention portion 80 and a second contact prevention portion 90. As shown in FIG.

[0095] (Configuration - Damage avoidance structure - First feature - First contact prevention part) Returning to Fig. 1, the first contact prevention part 80 is a first contact prevention means for preventing contact between the door-end side opening / closing body 20 and the upper frame material 13 by contacting one of the two visible surfaces of the upper frame material 13 (specifically, the blocking part 13j) with the first contact prevention part 80 when a first external force acts on the door-end side opening / closing body 20. As shown in Figs. 1 to 4, this first contact prevention part 80 is provided in the upper frame material 13, and includes a first contact prevention main body 81 and a first mounting part 82.

[0096] Here, the "first external force" refers to, for example, a pulling force acting on the door-end opening / closing body 20 from one side in the prospective direction (specifically, the inside side of the room) and a pushing force acting from the other side in the prospective direction (specifically, the outside side of the room).

[0097] (Configuration-Damage avoidance structure-First feature-First contact prevention part-First contact prevention body) Returning to Fig. 2, the first contact-prevention body 81 is the basic structure of the first contact-prevention part 80. This first contact-prevention body 81 is configured using, for example, a known contact-prevention member (one example is a guide roller member made of rubber (or made of other resin than rubber) or the like), and as shown in Figs. 2 and 3, is provided at a position where it can come into contact with the second connecting member 13i provided on the interior side facing surface piece 13b, and is rotatably connected to the first mounting part 82 by a fixture or the like.

[0098] (Configuration - Damage avoidance structure - First feature - First contact prevention part - First mounting part) Returning to Fig. 2, the first attachment portion 82 is a first attachment means for attaching the first contact prevention body 81 to the door-end side opening / closing body 20. This first attachment portion 82 is formed of a substantially flat steel plate-like body, and is provided below the first contact prevention body 81, as shown in Figs. 2 and 3.

[0099] Further, the specific shape and size of the first attachment portion 82 are arbitrary, but in this embodiment, they are set as follows.

[0100] That is, as shown in Figures 3 and 4(a), the planar shape of the first mounting portion 82 is set to be approximately L-shaped, and specifically, it has a first main body side mounting piece 82a located on the first contact prevention main body 81 side, and a first opening / closing body side mounting piece 82b located on the door end side opening / closing body 20 side.

[0101] The left-right length of the first body-side mounting piece 82a is set to be approximately the same as the left-right length of the first contact-prevention body 81. The front-rear length of the first body-side mounting piece 82a is set to be longer than the front-rear length of the door-end side opening / closing body 20 and shorter than the front-rear length of the upper frame material 13.

[0102] The left-right length of the first opening / closing body side mounting piece 82b is set to be longer than the left-right length of the first main body side mounting piece 82a and shorter than the left-right length of the end-side opening / closing body 20. The front-to-rear length of the first opening / closing body side mounting piece 82b is set to be shorter than (or approximately the same as) the front-to-rear length of the end-side opening / closing body 20.

[0103] Further, the first mounting portion 82 may be installed in any manner, but in this embodiment, the first mounting portion 82 is arranged so as to be approximately perpendicular to the indoor side facing surface piece 13b. Specifically, as shown in Fig. 2 and Fig. 3, the first mounting portion 82 is arranged approximately horizontally so that the longitudinal direction (specifically, the front-to-rear direction) of the first main body side mounting piece 82a is approximately perpendicular to the indoor side facing surface piece 13b in each of the side view and the plan view.

[0104] Such an installation makes it easier for the contact surface of the first contact prevention main body 81 and the second connecting member 13i to come into surface contact, thereby making it possible to suppress bending deformation of the first attachment portion 82 during the surface contact.

[0105] (Configuration - Damage avoidance structure - First feature - Second contact prevention part) Returning to Fig. 2, the second contact prevention part 90 is a second contact prevention means for preventing contact between the door-end side opening / closing body 20 and the upper frame material 13 by contacting the other of the two visible surfaces of the upper frame material 13 (specifically, the inspection cover 13g) with the second contact prevention part 90 when a second external force different from the first external force acts on the door-end side opening / closing body 20. This second contact prevention part 90 is formed separately from the first contact prevention part 80, and is provided in the upper frame material 13 as shown in Figs. 2, 3 and 5, and includes a second contact prevention main body 91 and a second mounting part 92.

[0106] Here, the "second external force" refers to, for example, a pushing force acting on the door-end opening / closing body 20 from one side in the prospective direction (specifically, the indoor side of the room) and a pulling force acting from the other side in the prospective direction (specifically, the outdoor side of the room).

[0107] (Configuration-Damage prevention structure-First feature-Second contact prevention part-Second contact prevention main body) Returning to Fig. 2, the second contact prevention body 91 is the basic structure of the second contact prevention part 90. This second contact prevention body 91 is configured using, for example, a known contact prevention member (one example is a guide roller member made of rubber (or made of other resin than rubber) or the like), and is provided at a position where it can come into contact with the inspection cover 13g as shown in Figs. 2 and 3, and is rotatably connected to the second attachment part 92 by a fixture or the like.

[0108] (Configuration - Damage avoidance structure - First feature - Second contact prevention part - Second mounting part) Returning to Fig. 2, the second mounting portion 92 is a second mounting means for mounting the second contact prevention body 91 to the door-end side opening / closing body 20 or the first mounting portion 82. This second mounting portion 92 is formed of a substantially flat steel plate-like body, and is provided below the second contact prevention body 91 as shown in Figs. 2 and 3.

[0109] Further, the specific shape and size of the second attachment portion 92 are arbitrary, but in this embodiment, they are set as follows.

[0110] That is, as shown in Figures 3 and 5(a), the planar shape of the second mounting portion 92 is set to be approximately linear, and specifically, it has a second main body side mounting piece 92a located on the second contact prevention main body 91 side, and a second opening / closing body side mounting piece 92b located on the door end side opening / closing body 20 side.

[0111] Moreover, the left-right length of the second body side mounting piece 92a is set to be approximately the same as the left-right length of the second contact-prevention main body 91. Moreover, the front-rear length of the second body side mounting piece 92a is set to be approximately the same as (or longer than) the front-rear length of the second contact-prevention main body 91.

[0112] The left-right length of the second opening / closing body side mounting piece 92b is set to be approximately the same as the left-right length of the second contact prevention main body 91. The front-rear length of the second opening / closing body side mounting piece 92b is set to be shorter than (or approximately the same as) the front-rear length of the end-side opening / closing body 20.

[0113] Further, the second mounting portion 92 may be installed in any manner, but in this embodiment, the second mounting portion 92 is disposed so as to be substantially perpendicular to the exterior-facing surface piece 13a. Specifically, as shown in Fig. 2 and Fig. 3, the second mounting portion 92 is disposed substantially horizontally so that the longitudinal direction (specifically, the front-rear direction) of the second opening / closing body side mounting piece 92b is substantially perpendicular to the inspection cover 13g in both side and plan views.

[0114] Such an installation makes it easier for the contact surface of the second contact prevention main body 91 and the inspection cover 13g to come into surface contact, thereby making it possible to prevent bending deformation of the second attachment portion 92 during the surface contact.

[0115] (Configuration - Damage avoidance structure - First feature - Other configurations) Returning to Figure 2, the specific configurations of the first contact prevention part 80 and the second contact prevention part 90 are arbitrary, but in the embodiment, the first contact prevention part 80 and the second contact prevention part 90 are provided within the upper frame material 13 at a position near the upper end part of the door end side opening / closing body 20.

[0116] 2 and 3, the first contact prevention part 80 is provided above the door-end side opening / closing body 20, and more specifically, is arranged so as to abut against the upper surface of the second door-end side piece 43b of the door-end side connection part 43. The second contact prevention part 90 is provided so that the second mounting part 92 is located above the first mounting part 82, and more specifically, is arranged so as to abut against the upper surface of the first mounting part 82.

[0117] This prevents the first contact prevention part 80 and the second contact prevention part 90 from being exposed to the outside, and effectively suppresses the shaking of the door end side opening / closing body 20 in the forward direction by the first contact prevention part 80 and the second contact prevention part 90, thereby improving the usability of the sliding door 1.

[0118] Due to this first feature, regardless of whether a first external force or a second external force acts on the door-end side opening / closing body 20, contact between the door-end side opening / closing body 20 and the upper frame material 13 can be prevented, and damage to the door-end side opening / closing body 20 can be avoided.

[0119] (Configuration - Damage avoidance structure - Second feature) As for the second feature of the damage avoidance structure, as shown in Figs. 3 and 4, the first attachment portion 82 is provided with a first connection portion 83, a first adjustment portion 84, and a notch portion 85.

[0120] (Configuration - Damage avoidance structure - Second feature - First connection part) The first connection part 83 is a first connection means for detachably connecting the first attachment part 82 or the second attachment part 92 to the door-end side opening / closing body 20. The first connection part 83 is configured using, for example, a known connection member (such as a bolt, for example) that can be detachably connected, and connects the first opening / closing body side attachment piece 82b to the door-end side opening / closing body 20 via an insertion hole (not shown) formed in the first adjustment part 84 and the second door-end side piece 43b of the door-end side connection part 43 and a connection member (such as a nut) provided on the door-end side opening / closing body 20, as shown in FIG.

[0121] This type of first connection portion 83 allows the first mounting portion 82 and the door-end side opening / closing body 20 to be freely connected and detached, and the first mounting portion 82 can be attached and detached from the door-end side opening / closing body 20 depending on the situation.

[0122] (Configuration - Damage avoidance structure - Second feature - First adjustment section) The first adjustment portion 84 is a first adjustment means for adjusting at least the relative position in the prospective direction between the first contact prevention portion 80 or the second contact prevention portion 90 and the door-end side opening / closing body 20. This first adjustment portion 84 is a long cutout, and specifically, the length of the short side of the first adjustment portion 84 is set to be approximately the same as the diameter of the first connection portion 83, and the length of the long side of the first adjustment portion 84 is set to be longer than the diameter of the first connection portion 83 (for example, about two to three times the diameter of the first connection portion 83).

[0123] 3 and 4(a), a plurality of first adjustment parts 84 are formed on the first opening / closing body side mounting piece 82b (two are formed in FIG. 3). Specifically, the first adjustment parts 84 are arranged such that the longitudinal direction of each first adjustment part 84 is approximately aligned with the front-rear direction.

[0124] Such a first adjustment part 84 makes it possible to adjust the relative positions of the first contact prevention part 80 and the door-end side opening / closing body 20 at least in the prospective direction, thereby improving the ease of installation of the first contact prevention part 80 and the door-end side opening / closing body 20.

[0125] (Configuration - Damage avoidance structure - Second feature - Notch) Returning to Fig. 3, the cutout 85 is for preventing contact between the first mounting part 82 and the third door end piece 43c of the door end connection part 43 when installing the first mounting part 82 on the door end side opening / closing body 20. This cutout 85 is a long cutout, and specifically, the length of the cutout 85 in the short direction is set to be thicker than the thickness of the third door end piece 43c, and the length of the cutout 85 in the long direction is set to be longer than the width of the third door end piece 43c.

[0126] 3 and 4(a), the notch 85 is formed in the first opening / closing body side mounting piece 82b. Specifically, the lengthwise direction of the notch 85 is disposed so as to be substantially aligned with the left-right direction.

[0127] Such a second feature can improve the usability of the first contact-preventing portion 80.

[0128] (Configuration - Damage avoidance structure - 3rd feature) Returning to FIG. 3, and as for the third feature of the damage avoidance structure, as shown in FIGS. 3 and 5, the second attachment portion 92 is provided with a second connection portion 93 and a second adjustment portion 94.

[0129] (Configuration - Damage avoidance structure - Third feature - Second connection part) 3, the second connection portion 93 is a second connection means for detachably connecting the first attachment portion 82 and the second attachment portion 92. The second connection portion 93 is configured using, for example, a known connection member (such as a bolt, for example) that is detachably connectable, and connects the first attachment portion 82 and the second attachment portion 92 as shown in FIG.

[0130] Specifically, the first mounting portion 82 (specifically, the first opening / closing body side mounting piece 82b) and the second mounting portion 92 (specifically, the second opening / closing body side mounting piece 92b) are connected via a mounting hole 86 (e.g., a screw hole, etc.) formed in the second adjustment portion 94 and the first opening / closing body side mounting piece 82b.

[0131] The second connection portion 93 allows the first mounting portion 82 and the second mounting portion 92 to be detachably connected, and either the first mounting portion 82 or the second mounting portion 92 can be attached or detached from the other depending on the situation. In addition, since the first mounting portion 82 and the second mounting portion 92 are connected via the second connection portion 93 so that the second mounting portion 92 is located higher than the first mounting portion 82, the second mounting portion 92 can be easily attached and detached via the inspection hatch 13f compared to when the first mounting portion 82 is located higher than the second mounting portion 92, and the installability of the second mounting portion 92 can be improved.

[0132] (Configuration - Damage avoidance structure - Third feature - Second adjustment section) The second adjustment portion 94 is an adjustment means and a second adjustment means for adjusting the relative positions at least in the prospective direction between the first contact prevention portion 80 and the second contact prevention portion 90. The second adjustment portion 94 is a long through hole, and specifically, the length of the second adjustment portion 94 in the short side direction is set to be approximately the same as the diameter of the second connection portion 93, and the length of the second adjustment portion 94 in the long side direction is set to be longer than the diameter of the second connection portion 93 (for example, about two to three times the diameter of the second connection portion 93).

[0133] 5(a), a plurality of second adjustment parts 94 are formed on the second opening / closing body side mounting piece 92b (two are formed in FIG. 5(a)). Specifically, the longitudinal direction of each second adjustment part 94 is arranged substantially along the left-right direction, and each second adjustment part 94 is arranged so that a part of the second adjustment part 94 overlaps with the mounting hole 86.

[0134] Such a second adjustment portion 94 makes it possible to adjust the relative positions of the first contact prevention portion 80 and the second contact prevention portion 90 at least in the prospective direction, thereby improving the ease of installation of the first contact prevention portion 80 and the second contact prevention portion 90.

[0135] Such a third feature can improve the usability of the second contact prevention portion 90.

[0136] (Configuration - Damage avoidance structure - 4th feature) Returning to FIG. 2, and with regard to the fourth feature of the damage avoidance structure, as shown in FIGS. 2 and 3, the upper frame material 13 is provided with a first contact avoidance portion 101 and a second contact avoidance portion 102.

[0137] (Configuration - Damage avoidance structure - Fourth feature - First contact avoidance part) Returning to Fig. 2, the first contact avoidance part 101 is a first contact avoidance means for avoiding direct contact between the first contact avoidance part 80 and the indoor side visible surface piece 13b by directly contacting the first contact avoidance part 101 and the first contact prevention part 80 when a first external force acts on the door end side opening / closing body 20. This first contact avoidance part 101 is formed of, for example, a steel plate (as an example, a stainless steel plate), and as shown in Fig. 2, is provided on one of the two visible surfaces of the upper side frame material 13 (specifically, the second connecting member 13i), and is connected to the second connecting member 13i by a fixture, adhesive, or the like.

[0138] Further, the specific shape and size of the first contact avoidance portion 101 are arbitrary, but in this embodiment they are set as follows.

[0139] That is, as shown in FIG. 2, the side shape of the first contact avoidance part 101 is set to a bent shape so as to be able to come into contact with the first contact prevention main body 81. As shown in FIG.

[0140] Moreover, the length of the first contact avoidance part 101 in the left-right direction is set to be longer than the opening / closing movement distance of the door-end side opening / closing body 20. Moreover, the length of the first contact avoidance part 101 in the up-down direction is set to be longer than (or shorter than, or substantially the same as) the length of the first contact prevention main body 81 in the up-down direction.

[0141] In addition, the first contact avoidance part 101 may be installed in any manner, but in this embodiment, it is arranged in a position where it can come into contact with the first contact prevention body 81 regardless of the open / closed state of the leading-side opening / closing body 20 and the trailing-side opening / closing body 30. Specifically, as shown in Fig. 2, it is arranged in a portion of the second connecting member 13i that corresponds to the portion between the leading-side rail part 41 and the upper end of the leading-side opening / closing body 20.

[0142] (Configuration - Damage avoidance structure - Fourth feature - Second contact avoidance part) Returning to Fig. 2, the second contact avoidance part 102 includes a second contact avoidance means for avoiding direct contact between the second contact avoidance part 90 and the inspection cover 13g by directly contacting the second contact avoidance part 102 and the second contact prevention part 90 when a second external force acts on the door-end side opening / closing body 20. The second contact avoidance part 102 is formed, for example, of a steel plate (as an example, a stainless steel plate), and is provided on the other of the two visible surfaces of the upper frame member 13 (specifically, the inspection cover 13g) as shown in Figs. 2 and 3, and is connected to the inspection cover 13g by a fixture, adhesive, or the like.

[0143] Further, the specific shape and size of the second contact avoidance portion 102 are arbitrary, but in this embodiment, they are set as follows.

[0144] That is, as shown in FIG. 2, the side shape of the second contact avoidance portion 102 is set to be substantially linear.

[0145] The length of the second contact avoidance part 102 in the left-right direction is set to be longer than the opening / closing movement distance of the door-end side opening / closing body 20. The length of the second contact avoidance part 102 in the up-down direction is set to be longer than (or shorter than, or substantially the same as) the length of the second contact prevention main body 91 in the up-down direction.

[0146] The second contact avoidance part 102 may be installed in any manner, but in this embodiment, it is arranged in a position where it can come into contact with the second contact prevention body 91 regardless of the open / closed state of the leading-edge side opening / closing body 20 and the trailing-edge side opening / closing body 30. Specifically, as shown in Fig. 2, it is arranged in a portion of the inspection cover 13g that corresponds to the portion between the trailing-edge side rail part 51 and the upper end of the leading-edge side opening / closing body 20.

[0147] This fourth feature makes it possible to avoid direct contact between each of the first contact prevention portion 80 and the second contact prevention portion 90 and the visible surface of the upper frame material 13, thereby preventing damage to the visible surface of the upper frame material 13.

[0148] (Sliding door action) Next, the operation of the sliding door 1 configured as described above will be described.

[0149] That is, for example, when a first external force acts on the door-end side opening / closing body 20 in the fully closed state (or the fully open state or the half-open state), the first contact prevention main body 81 and the first contact avoidance portion 101 come into direct contact, thereby preventing contact between the door-end side opening / closing body 20 and the upper frame material 13 (specifically, the blocking portion 13j) and relatively suppressing shaking of the door-end side opening / closing body 20 in the forward direction.

[0150] Furthermore, for example, when a second external force acts on the door-end side opening / closing body 20 in the fully closed state (or the fully open state or the half-open state), the second contact prevention body 91 and the second contact avoidance portion 102 come into direct contact with each other, thereby preventing contact between the door-end side opening / closing body 20 and the upper frame material 13 (specifically, the first lower side surface piece 13d) and relatively suppressing shaking of the door-end side opening / closing body 20 in the forward direction.

[0151] (How to install sliding doors) Next, a method for installing the sliding door 1 configured as described above will be described.

[0152] This installation method of the sliding door 1 is a method for installing the sliding door 1 in the opening 3, and includes a first installation step, a second installation step, a hanging step, a first adjustment step, and a second adjustment step.

[0153] (How to install sliding doors - First installation step) First, the first installation step will be described.

[0154] The first installation step is a step of providing the frame 10 in the opening 3.

[0155] Specifically, first, the leading edge frame material 11, trailing edge frame material 12, and upper frame material 13 are fixed to the frame body 2 by fasteners or the like. Note that the first contact avoidance portion 101 and the second contact avoidance portion 102 may be fixed to the upper frame material 13 in advance at a factory (or on-site) by fasteners or the like.

[0156] (How to install sliding doors - second installation step) Next, the second installation step will be described.

[0157] The second installation step is a step of providing the first contact prevention part 80 and the second contact prevention part 90 to the door-end side opening / closing body 20 after the first installation step (or before the first installation step).

[0158] Specifically, the first contact prevention part 80 is provided on the door-end side opening / closing body 20 by connecting the first attachment part 82 and the door-end side opening / closing body 20 via the first connection part 83 (specifically, temporary connection or final connection). In addition, the second contact prevention part 90 is provided on the door-end side opening / closing body 20 by connecting the first attachment part 82 and the second attachment part 92 via the second connection part 93 (specifically, temporary connection or final connection).

[0159] (How to install sliding doors - hanging process) Next, the hanging process will be described.

[0160] The hanging process is a process that takes place after or during the first installation process, in which a leading-side movement assist part 40 and a trailing-side movement assist part 50 are provided between the upper frame material 13 and each opening / closing body (specifically, the leading-side opening / closing body 20 and the trailing-side opening / closing body 30), and each opening / closing body is hung from the corresponding movement assist part.

[0161] Specifically, first, before the second installation step (or after the second installation step), the leading edge side rail portion 41 and the trailing edge side rail portion 51 are provided on the upper frame material 13. During the second installation step, the leading edge side roller portion 42 and the leading edge side opening / closing body 20 are connected via the leading edge side connection portion 43. Also, before the second installation step (or after the second installation step), the trailing edge side roller portion 52 and the trailing edge side opening / closing body 30 are connected via the trailing edge side connection portion 53.

[0162] Next, by providing the leading-side roller part 42 on the rail surface of the leading-side rail part 41, the leading-side opening / closing body 20 is suspended from the leading-side rail part 41 via the leading-side roller part 42 and the leading-side connecting part 43. Also, by providing the trailing-side roller part 52 on the rail surface of the trailing-side rail part 51, the trailing-side opening / closing body 30 is suspended from the trailing-side rail part 51 via the trailing-side roller part 52 and the trailing-side connecting part 53. After that, the automatic closing part 44, the fully open state maintaining part, the first braking part 45, the second braking part 46, and the interlocking part 54 are provided on the upper frame material 13, etc.

[0163] (How to install sliding doors - First adjustment step) Next, the first adjustment step will be described.

[0164] The first adjustment process is a process of adjusting the relative position between the first contact prevention part 80 and the door end side opening / closing body 20 at least in the prospective direction via the first adjustment part 84 provided on the first contact prevention part 80 after the second installation process and the hanging process.

[0165] Specifically, immediately after the second installation step and the hanging step (or after the second adjustment step), the first contact prevention part 80 is moved in the front-rear direction through the inspection hatch 13f to adjust the relative position in the above-mentioned projection direction, thereby adjusting the distance between the first contact prevention main body 81 and the second connecting member 13i. Alternatively, the door end side opening / closing body 20 is moved in the front-rear direction through the inspection hatch 13f to adjust the relative position in the above-mentioned projection direction, thereby adjusting the distance between the door end side opening / closing body 20 and the second connecting member 13i (or the blocking part 13j or the first lower side surface piece 13d).

[0166] (How to install sliding doors - second adjustment process) Next, the second adjustment step will be described.

[0167] The second adjustment process is a process of adjusting the relative positions of the first contact prevention part 80 and the second contact prevention part 90 at least in the prospective direction via the second adjustment part 94 provided on the second contact prevention part 90 after the second installation process and the hanging process.

[0168] Specifically, immediately after the second installation step and the hanging step (or after the first adjustment step), the first contact prevention part 80 is moved in the front-rear direction through the inspection hatch 13f to adjust the relative position in the above-mentioned projection direction, thereby adjusting the distance between the first contact prevention main body 81 and the second connecting member 13i. Alternatively, the second contact prevention part 90 is moved in the front-rear direction through the inspection hatch 13f to adjust the relative position in the above-mentioned projection direction, thereby adjusting the distance between the second contact prevention main body 91 and the inspection cover 13g (or the first lower side surface piece 13d). This completes the installation of the sliding door 1.

[0169] With this installation method, after the second installation step and the hanging step, the relative position between either the first contact prevention part 80 or the second contact prevention part 90 and the door-end side opening / closing body 20 can be adjusted at least in the projection direction, and the relative position between the first contact prevention part 80 and the second contact prevention part 90 can be adjusted at least in the projection direction. In particular, by performing the second adjustment step after the first adjustment step, the work of this step can be performed efficiently. Therefore, the first contact prevention part 80, the second contact prevention part 90, and the door-end side opening / closing body 20 can be accurately installed, and damage to the door-end side opening / closing body 20 can be avoided.

[0170] (Effects of the embodiment) Thus, according to the embodiment, there is a first contact prevention portion 80 provided on the door-end side opening / closing body 20, which prevents the door-end side opening / closing body 20 and the upper frame member 13 from coming into contact with one of the two visible surfaces of the upper frame member 13 when a first external force acts on the door-end side opening / closing body 20, and a second contact prevention portion 90 provided on the door-end side opening / closing body 20, which prevents the door-end side opening / closing body 20 and the upper frame member 13 from coming into contact with each other when a first external force acts on the door-end side opening / closing body 20. The upper frame material 13 has a second contact prevention portion 90 for preventing contact between the door-end side opening / closing body 20 and the upper frame material 13 when the first external force or the second external force acts on the door-end side opening / closing body 20, thereby preventing contact between the door-end side opening / closing body 20 and the upper frame material 13, and avoiding damage to the door-end side opening / closing body 20.

[0171] Furthermore, since the first contact prevention portion 80 and the second contact prevention portion 90 are provided within the upper frame material 13 at a position near the upper end of the door-end side opening / closing body 20, the first contact prevention portion 80 and the second contact prevention portion 90 are prevented from being exposed to the outside, and the first contact prevention portion 80 and the second contact prevention portion 90 can effectively suppress shaking of the door-end side opening / closing body 20 in the forward direction, thereby improving the usability of the sliding door 1.

[0172] In addition, the first contact prevention part 80 and the second contact prevention part 90 are formed separately from each other and are provided with a first adjustment part 84 for adjusting the relative position between the first contact prevention part 80 and the door-end side opening / closing body 20, at least in the prospective direction, and a second adjustment part 94 for adjusting the relative position between the first contact prevention part 80 and the second contact prevention part 90, at least in the prospective direction.This makes it possible to adjust the relative position between the first contact prevention part 80 and the door-end side opening / closing body 20, at least in the prospective direction, and the relative position between the first contact prevention part 80 and the second contact prevention part 90, at least in the prospective direction, thereby improving the ease of installation of the first contact prevention part 80 and the second contact prevention part 90.

[0173] In addition, the first mounting portion 82 is provided with a first connection portion 83 for detachably connecting the first mounting portion 82 to the door-end side opening / closing body 20, and a second connection portion 93 for detachably connecting the first mounting portion 82 to the second mounting portion 92. Therefore, the first mounting portion 82 can be detachably connected to the door-end side opening / closing body 20, and the first mounting portion 82 and the second mounting portion 92 can be detachably connected. Depending on the situation, the first mounting portion 82 can be attached and detached from the door-end side opening / closing body 20, and either the first mounting portion 82 or the second mounting portion 92 can be attached and detached from the other.

[0174] In addition, the first mounting portion 82 and the second mounting portion 92 are each formed from a substantially flat plate-like body, with the first mounting portion 82 positioned so as to be substantially perpendicular to one of the visible surfaces, and the second mounting portion 92 positioned so as to be substantially perpendicular to the other visible surface.This makes it easier to bring the contact surfaces of the first contact prevention main body 81 and the second contact prevention main body 91 into surface contact with the visible surface of the upper frame material 13, thereby preventing the first mounting portion 82 or the second mounting portion 92 from bending and deforming during the surface contact.

[0175] In addition, the upper frame material 13 is equipped with an inspection hatch 13f formed on the other visible surface and an inspection cover 13g for covering the inspection hatch 13f, and the first mounting portion 82 is connected to the door end side opening and closing body via the first connection portion 83, and the first mounting portion 82 and the second mounting portion 9 are connected via the second connection portion 93 so that the second mounting portion 9 is positioned higher than the first mounting portion 82.Therefore, the second mounting portion 92 can be easily attached and detached via the inspection hatch 13f compared to when the first mounting portion 82 is positioned higher than the second mounting portion 92, and the installability of the second mounting portion 92 can be improved.

[0176] In addition, since the upper frame material 13 is provided with a first contact avoidance portion 101 provided on one visible surface and a second contact avoidance portion 102 provided on the other visible surface, direct contact between each of the first contact prevention portion 80 and the second contact prevention portion 90 and the visible surface of the upper frame material 13 can be avoided, and damage to the visible surface of the upper frame material 13 can be avoided.

[0177] The method further includes a first installation step of providing the frame body 10 in the opening 3, a second installation step of providing the first contact prevention part 80 and the second contact prevention part 90 in the door-end side opening / closing body 20, a suspension step of providing a movement assisting means between the upper frame member 13 and each opening / closing body after or during the first installation step, and suspending each opening / closing body from the corresponding movement assisting means, and a relative movement between the first contact prevention part 80 and the door-end side opening / closing body 20 at least in the prospective direction via a first adjustment part 84 provided in the first contact prevention part 80 after the second installation step and the suspension step. Since the method includes a first adjustment step of adjusting the position, and a second adjustment step of adjusting the relative position of the first contact prevention part 80 and the second contact prevention part 90 at least in the prospective direction via the second adjustment part 94 provided in the second contact prevention part 90 after the second installation step and the hanging step, the relative position of the first contact prevention part 80 and the door-end side opening / closing body 20 at least in the prospective direction can be adjusted after the second installation step and the hanging step, and the relative position of the first contact prevention part 80 and the second contact prevention part 90 at least in the prospective direction can be adjusted. Therefore, the first contact prevention part 80, the second contact prevention part 90, and the door-end side opening / closing body 20 can be accurately installed, and damage to the door-end side opening / closing body 20 can be avoided.

[0178] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

[0183] In the above embodiment, the sliding door 1 is described as a single-opening sliding door, but is not limited thereto. For example, the sliding door may be a double-opening sliding door having two sets of a leading-side opening / closing body 20 and a trailing-side opening / closing body 30 that move in conjunction with each other to open and close.

[0184] (About the upper frame material) In the above embodiment, it has been described that the upper frame material 13 has a first contact avoidance portion 101 and a second contact avoidance portion 102, but this is not limited to this, and for example, at least one of the first contact avoidance portion 101 or the second contact avoidance portion 102 may be omitted.

[0185] Further, in the above embodiment, the inspection hatch 13f and the inspection cover 13g are described as being provided on the exterior sight piece 13a, but this is not limiting, and they may be provided, for example, on the interior sight piece 13b.

[0186] (First contact prevention part, second contact prevention part) In the above embodiment, the first contact prevention part 80 and the second contact prevention part 90 are described as being formed separately, but this is not limiting, and for example, they may be formed integrally. In this case, the first connection part 83, the first adjustment part 84, the second connection part 93, and the second adjustment part 94 may be omitted, and the first contact prevention part 80 and / or the second contact prevention part 90 may be fixed to the door-end side opening / closing body 20 by a fixing device or the like.

[0187] In the above embodiment, the first contact prevention part 80 is configured so that the first contact prevention body 81 can contact the second connecting member 13i provided on the interior side visible surface piece 13b, and the second contact prevention part 90 is configured so that the second contact prevention body 91 can contact the inspection cover 13g, but this is not limited thereto. For example, the first contact prevention part 80 may be configured so that the first contact prevention body 81 can contact the inspection cover 13g, and the second contact prevention part 90 may be configured so that the second contact prevention body 91 can contact the second connecting member 13i.

[0188] In the above embodiment, the first contact prevention part 80 and the second contact prevention part 90 are described as being provided in the upper frame member 13 at a position adjacent to the upper end of the door end side opening / closing body 20, but this is not limited thereto. For example, they may be provided in a position other than the position adjacent to the upper end of the door end side opening / closing body 20 in the upper frame member 13 (as an example, a position adjacent to the upper end of the upper frame member 13). Alternatively, the first contact prevention part 80 or the second contact prevention part 90 may be provided so that a part of them is exposed to the outside.

[0189] In the above embodiment, the first contact-prevention body 81 and the second contact-prevention body 91 are described as guide roller members, but are not limited to this and may be, for example, sliding members.

[0190] In the above embodiment, the second contact prevention part 90 is described as being provided so as to abut against the upper surface of the first contact prevention part 80, but this is not limited thereto. For example, the second contact prevention part 90 may be arranged so as to abut against the upper surface of the door end side opening / closing body 20 or the upper surface of the second door end side piece 43b of the door end side connecting part 43. In this case, the second adjustment part 94 may be omitted. Alternatively, instead of the second adjustment part 94 and the second connecting part 93, the second contact prevention part 90 may be provided with a first adjustment part 84 for adjusting the relative position between the second contact prevention part 90 and the door end side opening / closing body 20 at least in the prospective direction, and a first connecting part 83 for detachably connecting the second attachment part 92 and the door end side opening / closing body 20.

[0191] (Regarding the second adjustment part) In the above embodiment, the second adjustment portion 94 is provided on the second attachment portion 92, but this is not limited thereto. For example, instead of the second adjustment portion 94, a through hole that cannot adjust the relative positions of the first contact prevention portion 80 and the second contact prevention portion 90 in the prospective direction may be provided (note that the same applies to the first adjustment portion 84). In this case, the second adjustment step (or the first adjustment step) may be omitted in the installation method.

[0192] In the above embodiment, the second adjustment unit 94 is described as being capable of adjusting the relative position between the first contact prevention unit 80 and the door end side opening / closing body 20 in the projection direction, but this is not limited thereto.
