Description

[Technical field]

[0001] The present invention relates to a guide mechanism for a sliding door, a hanging door, and a booth. [Background technology]

[0002] Conventionally, booths for carrying out work and the like have been installed in offices, exhibition halls, public facilities, and the like (for example, see Patent Document 1). In particular, in recent years, the trend toward free address systems in offices and mobile work utilizing ICT (information and communication technology) such as mobile terminals and personal computers has progressed. As a result, there are an increasing number of opportunities to carry out work and the like in small booths at various destinations.

[0003] As the demand for booths has increased in recent years, there has been a demand for more compact booth doors. For example, in a booth with a hinged door, a space is required on the outside of the door for the door to open. If a horizontal sliding door is used instead of a hinged door, the space on the outside of the door is not required, but a space is required for the door to enter when opening, so an entrance space of the same width as the door is usually required next to the door.

[0004] In response to this, a booth that does not require a large amount of space on the outside or sides by using a swiveling sliding door is disclosed in, for example, Patent Document 1. With such a swiveling sliding door, if rails are provided on the floor inside the booth, there is a risk that objects may get caught in the rails or that booth users may trip over the rails. For this reason, for example, Patent Documents 2 and 3 disclose a suspended sliding door with a rail on the upper side.

[0005] In Patent Document 2, a guide member that supports the bottom surface of the door by magnetic force is provided on the floor surface located below the door in a suspended sliding door to prevent the door from swinging. In this case, the guide member is configured to be able to swing up and down so that users do not get their feet caught in the guide member when the door is not at the position of the guide member (when the door is open). Also, Patent Document 3 describes a structure in which a guide member remains engaged within the bottom frame of a suspended door in the closed position. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2021-008783 [Patent Document 2] Utility Model Registration No. 3208851 [Patent Document 3] JP 2020-066978 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the case of the above-mentioned Patent Document 2, since a guide member is provided on the floor surface, there is a risk that dirt or other objects may become caught in the guide member. Furthermore, in the case of Patent Document 3, the anti-sway function can only be performed where the guide member is present, and there was a problem in that the swing of the sliding door could not be sufficiently suppressed in positions where the guide member was not present. Therefore, there was a demand for a user-friendly door that would not have the inconvenience of users' feet getting caught or objects getting caught in the rails or guide members, as occurs when rails are installed on the floor, and that could also suppress the swinging of the sliding door as described above, and there was room for improvement in this regard.

[0008] Therefore, the present invention has been made in consideration of the above-mentioned circumstances, and provides a guide mechanism for a sliding door, a hanging door, and a booth that are easy to use and can regulate the movement of the sliding door at any position in the opening and closing movement direction, thereby suppressing the vibration of the sliding door. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention employs the following means. In other words, the sliding door guide mechanism of the present invention is a sliding door guide mechanism that opens and closes an entrance opening that communicates a first space and a second space, and includes a base provided below the sliding door, a guide holding member that extends from the lower part of the sliding door, passing through the second space side of the base and to the underside of the base, a guide member provided at the tip of the guide holding member, and a guide guide portion provided on the base and engaging the guide member movably along the opening and closing movement direction of the sliding door.

[0010] In the guide mechanism for the sliding door according to the present invention, a guide member is provided at a tip portion located below a guide holding member provided at the bottom of the sliding door, and as the sliding door moves to open or close, the guide member moves while being engaged with a guide portion disposed below the base and guided by the guide portion. In other words, the sliding door during opening and closing is supported by the guide portion via the guide member, so that the movement of the bottom of the sliding door is restricted, and it is possible to prevent the sliding door from coming out of the extension area of ​​the guide portion. Therefore, when the sliding door moves to open or close, or when it is stopped at any opening or closing position, it is possible to suppress the swing of the sliding door. In addition, in the present invention, the guide portion that engages with the guide member is located at the bottom of the base, and the top surface of the base does not have rails or the like arranged on the floor to guide the sliding door as in the past. Therefore, the guide mechanism of the present invention is easy to use and does not cause problems such as the user's feet getting caught in the rails or objects getting caught in the rails, which occurs when rails are arranged on the floor.

[0011] In addition, the guide mechanism for the sliding door of the present invention may be characterized in that an opening extending along the opening / closing movement direction is provided on the side of the base facing the second space, and the guide guide portion is a guide guide groove provided inside the opening and extending in the opening / closing movement direction.

[0012] In the guide mechanism for the sliding door constructed in this manner, the guide groove with which the guide member engages is provided on the inside of the opening provided in the base, so that the guide groove is not exposed to the second space, and it is possible to more reliably reduce problems such as objects getting caught in the guide groove or users getting their feet caught in it. Moreover, because the guide groove is located on the inside of the base, it is possible to improve the design.

[0013] Furthermore, in the guide mechanism for the sliding door according to the present invention, the guide guide groove may open downward, the guide holding member may be bent inward from the opening and extend below the guide guide groove, and the guide member may be a protrusion that protrudes upward from the tip of the guide holding member and engages with the guide guide groove.

[0014] In this case, since the opening of the guide groove faces downward, it is possible to prevent the movement of the guide member from being hindered by objects getting caught in the guide portion or by dust getting in. Therefore, the sliding door can be opened and closed in a stable position, and the swinging of the sliding door can be reliably suppressed. In addition, in the present invention, the tip of the guide holding member extends to the inside of the opening, and further the protrusion portion which is the guide member is engaged within the groove of the guide guide groove, so that the guide member is difficult to see from the second space side and is not exposed, which makes it easy to use and good from the standpoint of design.

[0015] Furthermore, the guide mechanism for the sliding door according to the present invention may be characterized in that a cutout recess is provided which communicates with the opening hole portion of the guide guide groove and is cut out on the second space side, the cutout recess is connected to the opening hole portion at a portion where the guide member cannot move after the guide member is fixed to the sliding door at the opening hole portion, and the protrusion provided on the guide holding member is arranged to be able to enter.

[0016] In the present invention, when the guide member is attached to the guide guide groove together with the guide holding member, the guide member enters the notch recess, and then the guide member is moved from the notch recess to a range of the opening hole of the guide guide groove in which the guide member can move after being fixed to the sliding door, so that the guide member can be movably arranged in the guide guide groove. Then, the sliding door can be installed by fixing the sliding door to the guide holding member with the guide member attached to the opening hole. Therefore, the notch recess is at a position that the guide member moving in the guide guide groove does not reach when the sliding door is opened and closed. Therefore, the guide member can be prevented from suddenly falling out of the guide guide groove when the sliding door is opened and closed.

[0017] In addition, the sliding door guide mechanism of the present invention may be characterized in that a height-adjustable adjuster is provided on the underside of the base, and the adjuster is provided in a position accessible from the opening.

[0018] In the guide mechanism for the sliding door constructed in this way, the opening under the base where the guide holding member is located can be used as the space required for adjusting the unevenness of the base. Therefore, the adjuster provided on the underside of the base can be accessed from the opening, and the height of the base can be adjusted by operating the adjuster.

[0019] In addition, in the guide mechanism for a sliding door according to the present invention, it is preferable that the guide holding member is provided at a door tip portion of the sliding door.

[0020] In the guide mechanism for the sliding door configured in this manner, the door end side of the sliding door is supported by the guide portion through the guide member, so that the sliding door can be stabilized. In addition, since the guide holding member and the guide member are disposed only on the door end side of the sliding door, when the sliding door is fully opened, the guide holding member and the guide member are positioned near the entrance opening. Therefore, the accommodation area secured for the passage of the guide holding member and the guide member can be reduced or eliminated, and the space efficiency of the first space can be improved.

[0021] In addition, in the guide mechanism for the sliding door according to the present invention, the opening and closing movement direction of the sliding door may be curved in an arc shape centered on a rotation axis located in the first space, and the sliding door may enter the first space in an open state by rotating about the rotation axis.

[0022] In the guide mechanism for the sliding door configured in this manner, when a pivoting sliding door is used, the open sliding door enters the first space, but there is no need to provide a separate groove-shaped accommodation section in the first space or the second space to accommodate the open sliding door. Moreover, even if the sliding door is a pivoting type, the guide member is supported by the guide guide section in a state in which it is engaged so as to be able to open and close, so the sliding door can be opened and closed in a stable position and the swinging of the sliding door can be suppressed.

[0023] In addition, in the guide mechanism for a sliding door according to the present invention, the sliding door may be a hanging door.

[0024] With the sliding door guide mechanism configured in this manner, it is possible to provide an excellent hanging door that can restrict the movement of the sliding door at any position in the opening and closing movement direction, thereby suppressing the swinging of the sliding door, as described above.

[0025] The hanging door according to the present invention is provided with the above-mentioned guide mechanism for the sliding door.

[0026] As described above, the present invention can provide an excellent hanging door that can restrict the movement of the sliding door at any position in the opening / closing movement direction and suppress vibration of the sliding door.

[0027] The booth according to the present invention is also provided with the above-mentioned guide mechanism for the sliding door.

[0028] As described above, the present invention can provide an excellent booth in which the movement of the sliding door can be restricted at any position in the opening / closing movement direction, thereby suppressing the swinging of the sliding door. Effect of the Invention

[0029] According to the guide mechanism for a sliding door, hanging door, and booth of the present invention, the movement of the sliding door can be restricted at any position in the opening / closing movement direction, thereby suppressing vibration of the sliding door.

[0040] Between a pair of pillars 31, 31 provided on the front side of the outer wall 3, there are a front wall 32A fixed to the left pillar 31, and an entrance opening E forming an entrance / exit for users, where a sliding door 4 is arranged so as to be able to open and close between the front wall 32A and the right pillar 31. The front wall 32A is erected on the upper surface of the floor 2, and the lower part of the front wall 32A and the lower part of the right pillar 31 are connected by the entrance / exit part 23 of the floor 2. The right wall portion 32B, the left wall portion 32C, and the rear wall portion 32D are erected on the upper surface of the floor portion 2, and both ends thereof are connected to the pillars 31.

[0041] As shown in FIG. 1, a top plate 71 used as a desk is provided on the rear side of the internal space K1 surrounded by the front wall 32A, the right wall 32B, the left wall 32C, and the rear wall 32D. That is, the top plate 71 is located opposite the entrance opening E with a chair (not shown) between them. The top plate 71 is attached to the inner wall surface of the rear wall 32D in contact with the rear wall 32D and is provided so as to extend forward from the rear wall 32D. The right edge of the top plate 71 is fixed to the right wall 32B, and the left edge is fixed to the left wall 32C. The height of the top plate 71 is set to a height that can be used by a user seated on a chair (not shown). The position of the top plate 71 in the booth 1 is not limited to the position opposite the entrance opening E as in this embodiment, and may be in another position or direction.

[0042] The ceiling wall 33 is supported from below by the columns 31 and the side walls 32, thereby closing off the internal space K1 from above. The ceiling wall 33 includes a ceiling frame (not shown) and a ceiling panel 33A. The ceiling frame is a frame-like member that surrounds the ceiling panel 33A in the horizontal direction and is connected to the periphery of the ceiling panel 33A, and is fixed to the upper ends of the columns 31 and the side walls 32. The ceiling panel 33A is a plate-like member that is supported by the ceiling frame and is arranged inside the ceiling frame in a plan view. In this embodiment, an equipment housing section 72 for housing a part of the booth equipment 7 is provided above the ceiling panel 33A.

[0043] As shown in FIG. 1, the sliding door 4 is a hanging door that is suspended and supported by an upper guide mechanism 5 so as to be movable to open and close. The sliding door 4 is a door body curved in an arc shape centered on the pivot axis C shown in Fig. 3, and is capable of opening and closing the entrance opening E by an upper guide mechanism 5. The sliding door 4 includes a glass panel 41, an upper edge frame 42, a lower edge frame 43, and a side edge frame 44 (see Figs. 4 and 5). The sliding door 4 pivots about the pivot axis C and enters the internal space K1 in an open state.

[0044] The glass panel 41 is a panel body made of glass and has a rectangular shape when viewed from the front and rear. Although the glass panel 41 is used to ensure the light transmittance of the sliding door 4, a panel body made of another material can be used if light transmittance is not required.

[0045] The upper edge frame 42 is a frame member joined to the upper edge of the glass panel 41. The lower edge frame 43 is a frame member joined to the lower edge of the glass panel 41. The side edge frames 44 are frame members joined to the right and left edges of the glass panel 41, and are fixed to the ends of the upper edge frame 42 and the lower edge frame 43 by bolts (not shown). Two such side edge frames 44 are provided in this embodiment. The upper edge frame 42, the lower edge frame 43, and the side edge frames 44 are formed of, for example, an aluminum alloy.

[0046] The sliding door 4 has a curved shape such that the center part bulges toward the external space K2 in a plan view. As shown in Fig. 3, the center part of the sliding door 4 protrudes toward the external space K2 from the outer wall surface of the front wall part 32A in a plan view when the sliding door 4 is placed in a closed position that closes the entrance opening E. In other words, as shown in Fig. 2, when the sliding door 4 is closed, the center part of the sliding door 4 protrudes forward from the outer wall surface of the front wall part 32A. Such a sliding door 4 is capable of pivoting about a pivot axis C along the vertical direction so as to open and close the entrance opening E.

[0047] As shown in FIG. 1, the upper guide mechanism 5 is suspended and supported on the front side of the ceiling wall 33, and is disposed above the entrance opening E provided in the front wall portion 32A. The upper guide mechanism 5 is a mechanism that supports the sliding door 4 so that it can slide in the circumferential direction centered on the pivot axis C shown in FIG. 3 along the vertical direction. That is, the upper edge frame 42 of the sliding door 4 is supported by the upper guide mechanism 5. For example, the upper guide mechanism 5 may be equipped with a linear motor (not shown) or the like. When the upper guide mechanism 5 is equipped with a linear motor in this way, the sliding door 4 is automatically moved.

[0048] As shown in Figures 4 to 7, the lower guide mechanism 6 comprises a base 60 provided below the sliding door 4, a guide holding member 61 extending from the lower part of the sliding door 4 through the external space K2 side of the base 60 to the underside of the base 60, a guide member 62 provided at the tip 61a of the guide holding member 61, and a guide guide groove 63 (guide guide portion) provided on the base 60 and engaging with the guide member 62 movably along the opening / closing movement direction S of the sliding door 4.

[0049] An opening 65 extending along the opening / closing movement direction S is provided on an outer surface 60a (side surface) of the base 60 facing the external space K2. The adjuster 22 provided on the lower surface 2a of the floor portion 2 is provided at a position accessible from the opening 65.

[0050] The guide groove 63 is disposed on the lower surface 60b of the base 60, inside the opening 65. The guide groove 63 is provided at a position overlapping with the sliding door 4 in a closed state when viewed from above, and extends in the same direction as the opening / closing movement direction S of the sliding door 4. That is, the guide groove 63 is curved in an arc shape centered on the pivot axis C located in the internal space K1. The guide groove 63 has an opening 63a that opens downward.

[0051] 2, 5 and 6, a notched recess 63c is provided on the lower surface 60b of the base 60, which is connected to the opening hole 63a of the guide guide groove 63 and is cut out on the external space K2 side. The notched recess 63c is connected to the opening hole 63a at a portion of the opening hole 63a that cannot move after the guide member 62 is fixed to the sliding door 4, and is provided so that a guide roller 621 provided on the guide holding member 61 can enter.

[0052] The guide holding member 61 is provided at the door end portion 4a of the lower edge frame 43 of the sliding door 4. The guide holding member 61 is made of a strip-shaped plate material and has a first member 611 extending outward from the lower portion of the sliding door 4, a second member 612 extending from the outer end of the first member 611 to the lower side of the base 60 passing through the outer surface 60a of the base 60 on the external space K2 side, and a third member 613 bending from the lower end of the second member 612 further toward the inside of the opening 65 and extending to the lower side of the guide guide groove 63. The tip portion 61a is located at the tip of the third member 613. The length of the third member 613 is set to a dimension longer than the length of the first member 611. The tip portion of the third member 613 (i.e., the portion to which the guide roller 621 is attached) protrudes toward the internal space K1 side more than the first member 611 in a top view.

[0053] 7, when attaching the guide holding member 61, the guide holding member 61 is laid down so that the upper side faces the front, and the guide roller 621 is inserted into the notched recess 63c from below. Then, when the guide holding member 61 is rotated so as to stand up, since the length of the second member 612 (the distance between the first member 611 and the third member 613) is slightly longer than the length in the height direction of the base 60, the notched recess 63c is on the front side (external space K2 side), so that the guide holding member 61 can be attached even if the length of the third member 613 is longer than the length of the first member 611.

[0054] The guide member 62 is a protrusion that protrudes upward from the tip 61a of the guide holding member 61 and engages with the guide guide groove 63. The guide member 62 has a guide roller 621 with a rotation axis in the up-down direction. The guide roller 621 is provided so as to be rotatable by contact with the inner surface of the guide guide groove 63 when the sliding door 4 moves to open or close.

[0055] In this way, by providing the notched recess 63c in the guide guide groove 63 and further making the length of the second member 612 of the guide holding member 61 greater than the height dimension of the base 60, the guide roller 621 can be easily inserted into the notched recess 63c. Therefore, when attaching the guide member 62 to the guide guide groove 63 together with the guide holding member 61, the guide roller 621 is inserted into the notched recess 63c, and then the guide roller 621 is moved from the notched recess 63c to the opening hole portion 63a of the guide guide groove 63, whereby the guide member 62 can be positioned within the movement range of the opening hole portion 63a.

[0056] When using the booth 1 of this embodiment, the sliding door 4 is automatically or manually moved in the opening direction so as to rotate about the rotation axis C, thereby opening the entrance / exit opening E. With the entrance / exit opening E open, a user enters the internal space K1, and the sliding door 4 is automatically or manually closed.

[0057] In the lower guide mechanism 6 provided in the booth 1 configured in this manner, a guide member 62 is provided at a tip portion 61a located below a guide holding member 61 provided at the bottom of the sliding door 4, and as the sliding door 4 moves to open or close, the guide member 62 moves while being guided by a guide guide groove 63 arranged below the base while being engaged with the guide guide groove 63. That is, the sliding door 4 during opening / closing movement is supported by the guide groove 63 via the guide member 62, and the movement of the lower part of the sliding door 4 is restricted, and it is possible to prevent the sliding door 4 from coming out of the extending area of ​​the guide groove 63. Therefore, when the sliding door 4 is opened / closed or stopped at any opening / closing position, it is possible to suppress the swinging of the sliding door 4.

[0058] In this embodiment, the guide groove 63 engaging with the guide member 62 is located at the bottom of the base 60, and no rails or the like for guiding the sliding door 4 are disposed on the floor 2 on the top surface of the base 60 as in the conventional configuration. Therefore, the lower guide mechanism 6 of this embodiment prevents the user's feet from getting caught in the rails or objects from getting caught in the rails as occurs when rails are provided on the floor, and provides good usability.

[0059] In this embodiment, the guide groove 63 with which the guide member 62 engages is provided inside the opening 65 provided in the base 60, so that the guide groove 63 is not exposed to the external space K2, and it is possible to more reliably reduce problems such as an object being caught in the guide groove 63 or a user's foot being caught in the guide groove 63. Moreover, because the guide groove 63 is located inside the base, it is possible to improve the design.

[0060] In addition, in this embodiment, since the opening of the guide groove 63 faces downward, it is possible to prevent the movement of the guide member 62 from being hindered due to an object being caught in the guide groove 63 or dust getting in. Therefore, the sliding door 4 can be opened and closed in a stable position, and the swinging of the sliding door 4 can be reliably suppressed. In addition, in this embodiment, the tip 61a of the guide holding member 61 extends to the inside of the opening 65, and further the guide roller 621 which is the guide member 62 is engaged within the groove of the guide guide groove 63. Therefore, the guide member 62 is not easily visible from the external space K2 side and is not exposed, which is convenient to use and also favorable from the standpoint of design.

[0061] In addition, in this embodiment, when the sliding door 4 is opened or closed, the guide rollers 621 rotate inside the guide grooves 63, so that the sliding door 4 can be opened and closed smoothly. In other words, since the movement of the guide member 62 consisting of the guide rollers 621 is prevented from being hindered, the sliding door 4 can be opened and closed in a stable posture, and the swinging of the sliding door 4 can be reliably prevented.

[0062] In this embodiment, a notched recess 63c is provided which is connected to the opening hole 63a of the guide guiding groove 63 and is cut out on the external space K2 side. The notched recess 63c is connected to the opening hole 63a at a portion of the opening hole 63a which cannot move after the guide member 62 is fixed to the sliding door 4, and is configured to allow the guide roller 621 provided on the guide holding member 61 to enter. As a result, when the guide member 62 is attached to the guide guide groove 63 together with the guide holding member 61, the guide member 62 is inserted into the notch recess 63c, and then the guide member 62 is moved from the notch recess 63c to a movable range of the opening hole portion 63a of the guide guide groove 63 in the guide member 62 after the guide member 62 is fixed to the sliding door 4, so that the guide member 62 can be movably disposed in the guide guide groove 63. Then, the sliding door 4 can be installed by fixing the guide member 62 to the guide holding member 61 with the guide member 62 attached to the opening hole portion 63a. Therefore, the notch recess 63c is a position that the guide member 62 moving in the guide guide groove 63 does not reach when the sliding door 4 is opened and closed. Therefore, the guide member 62 can be prevented from suddenly falling out of the guide guide groove 63 when the sliding door 4 is opened and closed.

[0063] In this embodiment, the opening 65 below the base 60 on which the guide holding member 61 is disposed can be used as a space required for adjusting unevenness of the base 60. Therefore, the adjuster 22 provided on the lower surface 60b of the base 60 can be accessed from the opening 65, and the height of the base 60 can be adjusted by operating the adjuster 22.

[0064] Furthermore, in this embodiment, since the door end side of the sliding door 4 is supported by the guide member 62 in the guide groove 63, the sliding door 4 can be stabilized. In addition, since the guide holding member 61 and the guide member 62 are disposed only on the door end side of the sliding door 4, when the sliding door 4 is fully opened, the guide holding member 61 and the guide member 62 are positioned near the entrance / exit opening E. Therefore, the accommodation area secured for the passage of the guide holding member 61 and the guide member 62 can be reduced or eliminated, and the space efficiency of the internal space K1 can be improved.

[0065] In addition, when a pivoting type sliding door 4 is used as in this embodiment, the open sliding door 4 enters the internal space K1, but there is no need to provide a separate groove-shaped accommodation section in the internal space K1 or the external space K2 to accommodate the open sliding door 4. Moreover, even if the sliding door 4 is a pivoting type, the guide member 62 is supported by the guide guide groove 63 in a state of being engaged so as to be openable and closable, so that the sliding door 4 can be opened and closed in a stable posture and the swinging of the sliding door 4 can be suppressed.

[0066] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0067] For example, in the embodiment described above, the booth 1 is taken as an example of an application target of the guide mechanism, with the inside of the booth being the internal space (first space) and the outside of the booth being the external space (second space), but the guide mechanism can also be applied to a sliding door provided on a partition of an entrance / exit opening where the inside and outside spaces are not clear, unlike the booth 1. For example, in the case of a sliding door provided on a partition between adjacent rooms within a room, the internal space of one room is the first space, and the internal space of the other room is the second space.

[0068] In addition, in this embodiment, the swingable sliding door 4 is taken as an example of an application of the guide mechanism, but the application is not limited to the swingable type. For example, the guide mechanism can be applied to a sliding door that can be opened and closed linearly in the width direction.

[0069] In this embodiment, the base 60 and the floor 2 of the lower guide mechanism 6 are separate bodies, but it is also possible for the base 60 and the floor 2 to be provided integrally as a base.

[0070] Furthermore, the opening 65 provided below the base 60 may be omitted.

[0071] In the present embodiment, the guide groove 63 opens downward on the lower surface 60b of the base 60, but is not limited to such a configuration. For example, the opening of the guide groove 63 may be located on the outer surface 60a of the base 60.

[0072] Furthermore, in this embodiment, the guide member 62 has a guide roller 621 protruding upward from the tip 61a of the guide holding member 61, but is not limited to the guide roller 621. For example, the guide member 62 may be a protruding member that simply protrudes upward from the tip 61a of the guide holding member 61.

[0073] In the embodiment, the booth 1 in which only one user can enter the internal space K1 has been described. However, the present invention is not limited to this, and may be applied to a booth in which multiple people can enter the internal space K1.

[0074] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
