Description

  The present invention relates to a mobile partition device, and more particularly to a mobile partition device in which a whole room from a ceiling to a floor surface can be closed or opened to partition a large room into small rooms.

  Conventionally, multiple movable panels can be moved in the direction parallel to the panel surface (in-plane direction) along the rail provided on the ceiling in the large room, and all the movable panels are connected to one end of the rail. Various types of mobile partition devices that can be rotated by 90 degrees in a section are provided. This type of movable partitioning device is a one-side end portion of the rail, and the movable panel is rotated 90 degrees so that the panel surface is orthogonal to the rail, and the surfaces are overlapped and stored compactly. And a mode in which the moving panel is rotated 90 degrees and pulled out from one end of the rail along the rail, each moving panel is connected in a straight line, and the large room is divided into small rooms To do. Then, when the movable panel is installed at a predetermined position, the movable panel is made immovable and the gap between the floor surface and the ceiling is closed.

  In Patent Document 1, a panel suspended from a ceiling rail and movable along the rail is pivotally attached to the other end of the rotating piece pivotally attached to the panel and to the headboard or baseboard. A partition panel press-contacting device is disclosed in which the other end of the rotating piece is connected to a pin, and a spring for holding the rotating pieces at a predetermined angle is provided on the shaft of the pin and the panel-side rotating piece. When the panel is movable, the headboard and baseboard are close to the panel, away from the ceiling rail and the floor, and the end of the headboard and baseboard protrudes from the front of the panel in the moving direction. Then, the panel is moved, and the end of the headboard and the baseboard collides with the wall or the end of the preceding panel, so that both the rotating pieces rotate against the elastic force of the spring and It is also disclosed that the baseboards are pressed against the ceiling rail and the floor, respectively, and fill the gaps. Here, in a state where the headboard and the baseboard are in pressure contact with the ceiling rail and the floor surface, respectively, the headboard and the baseboard are positioned above and below to fit within the lateral width of the panel.

  Patent Document 2 discloses a moving partition device that is supported by a rail installed on a ceiling and that partitions a room by a plurality of partition panels that move along a moving path formed by the rail. The upper and lower part closing member that closes the gap between the panel main body and the ceiling and floor by moving up and down from the upper and lower ends of the panel main body to the partition panel is always outside from one end of the panel main body. Moving partition device that protrudes toward the other side and is supported by being moved into the other side end side while being pushed into the panel main body by abutting the side end of the wall surface or other partition panel. Is disclosed. Here, the means for supporting the upper and lower closing member is pivotally attached at one end to the upper and lower closing member with a shaft facing in the front-rear direction, and a long hole provided at the other end is provided at the upper and lower ends of the panel body. Each end is locked to the pin and a part of the upper and lower closing member that is slightly separated from the shaft, and a direction in which they are separated from each other.

Here, the ones described in Patent Documents 1 and 2 are of a type that press-contacts the floor surface and the ceiling, and the press-contact mechanism is provided at the top and bottom of the panel and is a link mechanism, so the number of parts is large. As the number of assembly steps increases, the cost tends to increase, and the panel height is adjusted according to the distance between the ceiling and the floor to set the pressure contact strength, making construction difficult. There is a problem. In addition, after the headboard (upper closing member) and the baseboard (lower closing member) protruding in the direction of panel movement are abutted against the wall surface and the other end face on the front side of the panel, they are pushed in further and exceed the top dead center of the link member. If the panel is heavy, a large force is required. In particular, in a state where the angle of the link member is shallow, an especially large force is required, and a smooth operation cannot be expected.

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the lower load system in which the upper part of the movable panel is guided by the guide rail provided on the ceiling and the lower part travels on the floor surface, or the movable panel. A movable partition that is suspended from a guide rail provided on the ceiling by a guide roller provided at the upper end, and in which a plurality of movable panels are linearly aligned along the guide rail and then set in a movement restricted state It is a device that can be smoothly moved from a movement restricted state to a movable state after moving the movable panel to a predetermined position, or can be smoothly moved by a simple operation, and the number of parts is small. It is an object of the present invention to provide a mobile partition device that is easy to assemble and excellent in appearance.

  In order to solve the above-mentioned problem, the present invention travels on the floor surface with a rolling wheel provided at the lower end of the moving panel, and a guide roller or a guide slider provided at the upper end of the moving panel is provided on the ceiling. A movable partition device that moves and guides along a rail, aligns a plurality of moving panels along a guide rail, and then lifts a rolling wheel by a lift mechanism to enter a movement restricted state. The mechanism arranges a baseboard member in a recessed groove portion opened downward along the lower end of the panel body, and fixes a guide member whose bottom surface is an inclined guiding surface to the left and right sides of the recessed groove portion. A roller that rolls the inclined guide surface is provided on the upper surface side of both ends of the baseboard member, and a tension coil spring is engaged between an appropriate position in the concave groove portion and the baseboard member, and the roller is inclined and guided. Along the surface The base plate member is elastically urged diagonally upward in the upward direction, and the roller is controlled by the lateral external force applied to the panel body by restricting the movement of the base plate member and the lowermost part of the inclined guide surface. The movable partition device is configured such that the baseboard member is in pressure contact with the floor surface (claim 1).

  Here, when the baseboard member is in an unloaded state, the baseboard member is lifted so that the roller is positioned at the uppermost portion of the inclined guide surface, and one end portion of the baseboard member protrudes from the side end of the panel body. When the rolling ring fixed in the groove of the panel body is grounded to the floor surface through the opening of the baseboard member and the baseboard member is positioned directly below the panel body, the roller Is preferably located at the lowermost part of the inclined guide surface (claim 2).

  Further, the guide member is a block-shaped member in which a ridge portion is formed in the center portion of the lower surface, and the inclined guide surfaces are formed on both sides of the ridge portion, and the support attached to the upper surface side of the baseboard member It is preferable that a pair of the rollers that roll on both inclined guide surfaces is provided on both sides of the member.

  Further, the guide member is a block-shaped member in which an inclined hole penetrating front and back is formed in the central portion, the upper edge portion of the inclined hole is the inclined guide surface, and the lower edge portion of the inclined hole is a restricting portion. A pair of rollers is held by a rotating shaft on a support member attached to the upper surface side of the baseboard member, the rotating shaft passes through the inclined hole of the guide member, and the regulating portion is sandwiched between the rollers. It is also preferable that the rollers are positioned so that both rollers roll in contact with the inclined guide surface.

  Further, the inclined guide surface of the guide member is provided with a concave portion that engages the roller at the uppermost part and the lowermost part, and has a continuous shape with an inclined curved surface that smoothly changes between the concave parts, More preferably, the roller is engaged in a metastable state in the concave portion when rising and lowering.

  In the mobile partition device according to the first aspect of the present invention as described above, the roller provided on the baseboard member with the inclined guide surface provided on the fixed side of the panel body rolls, and the baseboard member is pulled with a coil spring. Since it is a simple structure that elastically biases upward, not only the operation of the baseboard member is smooth, but also the number of parts is small, so it is easy to assemble and the cost can be reduced. Since it is provided in the recessed groove part opened downward of the panel body, it is excellent in appearance. Further, even if the baseboard member is not operated, it is possible to realize the movement restricted state and the movable state by holding only the upper part of the movable panel and pushing along the guide rail, and the baseboard member is provided on the floor. In the state of movement restriction where the rolling wheel is lifted up on the surface, the baseboard member literally closes the gap between the panel main body and the floor as a baseboard, and the panel main body is located immediately above the baseboard member. As a result, a sense of unity without any discomfort can be achieved in terms of appearance.

  According to claim 2, when the baseboard member is in an unloaded state, the baseboard member is raised so that the roller is positioned at the uppermost part of the inclined guide surface, and one end of the baseboard member is on the panel body side. When the rolling wheel fixed in the concave groove of the panel body is grounded to the floor surface through the opening of the baseboard member, and the baseboard member is located directly below the panel body In addition, since the roller is positioned at the lowermost part of the inclined guide surface, it is not particularly necessary to hold the baseboard member, and the operation is highly reliable.

  According to claim 3, the guide member is a block-like member in which a ridge portion is formed at the center of the lower surface and the inclined guide surfaces are formed on both sides of the ridge portion, and the upper surface of the baseboard member. Since the pair of rollers that roll on both inclined guide surfaces is provided on both sides of the support member attached to the side, the baseboard member does not rattle in the front and back direction, and can be raised and lowered stably in an oblique direction. it can.

  According to claim 4, in a movable state in which the front end portion of the baseboard member protrudes from one end face of the panel body, a downward external force is unexpectedly applied, such as stepping on the protruding portion of the baseboard member with a foot. In addition, since the rotating shaft stops against the restricting portion of the guide member, the baseboard member is not greatly displaced downward.

  According to claim 5, the inclined guide surface of the guide member has a concave portion that engages the roller at the uppermost portion and the lowermost portion, and has a shape that is continuous with an inclined curved surface that smoothly changes between the concave portions. Since the roller is engaged in the metastable state in the concave portion when the baseboard member is raised and lowered, the state where the baseboard member is raised and lowered can be maintained in the metastable state.

  Next, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. 1 and 2 are explanatory views for explaining the operation principle of the mobile partition device according to the present invention, FIG. 3 is an exploded perspective view of the movable panel, and FIGS. 4 to 14 show the details thereof.

The guide rail 4 includes a direction changing portion 4A corresponding to one end portion and a series holding portion 4B other than the direction changing portion, and the direction changing portion 4A has a structure in which a lower half of the series holding portion 4B is cut out. Since there is a step 4C at the boundary, a smoother is provided at the upper end of the moving panel 1 on the front side in the moving direction so that the moving panel 1 can be smoothly moved from the direction changing portion 4A to the series holding portion 4B. 7 is provided. Then, the movable panel 1 is moved to a predetermined position and arranged in series, and the lift mechanism 5 floats the rolling wheels 2,. A stopper 8 that is locked to the floor surface F is provided at the lower end on the rear side in the direction.

  The movable panel 1 is constructed by attaching the rolling wheels 2,..., The guide roller 3, the lift mechanism 5, the smoother 7, the stopper 8 to the panel body 9 and rubber packings 10, 10 on both end faces. Here, in this embodiment, the panel main body 9 is constituted by a frame composed of vertical vertical frames 11 and 11, an upper frame 12, a lower frame 13 and a horizontal rail 14 made of an extruded aluminum material. It is a retained structure.

  The vertical frame 11 is a flat hollow member that forms a groove portion 16 for holding the panel plate 15 along the center of one side surface, and a pair of engagement members having an L-shaped cross section along both side portions on the other side surface. Stop pieces 17 and 17 are projected. Here, the bent portions of the front end portions of the locking pieces 17 and 17 are directed to face each other, and the rubber packing 10 is fitted to the locking pieces 17 and 17 and the stopper 8 can be slid up and down. Is engaged. The upper frame 12 and the lower frame 13 are the same mold material, and vertical plates 19 and 19 are formed on both sides of a flat hollow reinforcing rod 18 similar to the vertical frame 11, and a concave groove 20 is formed inside. A groove portion 21 for holding the panel plate 15 is formed on the outer surface of the reinforcing rod 18, and engagement grooves 22 and 22 are formed at the tip portions facing the recessed groove portions 20 of the vertical plates 19 and 19, respectively. Each is formed. The horizontal rail 14 is a hollow member that is flat in the vertical direction, and is formed with groove portions 23 and 23 that hold the panel plate 15 along the center of the vertical surface.

  The panel body 9 is connected to the inner side surfaces of the upper and lower ends of the vertical frame 11 using L metal fittings 24 in a state where the ends of the upper frame 12 and the lower frame 13 face each other. The end of the horizontal crosspiece 14 is abutted against the upper and lower intermediate portions of 11 and connected by appropriate means such as screws, and the edge portions of the panel plate 15 are held in the groove portions 16, 18 and 23 of these members. Here, it is an inner surface of the upper and lower ends of the vertical frame 11, cuts out a position where the ends of the upper frame 12 and the lower frame 13 are abutted, and is an outer surface of the upper and lower ends, At positions corresponding to the insides of the recessed groove portions 20 of the frame 12 and the lower frame 13, vertically long slit grooves 25, 25 are formed at the end portions at the outer positions of the both locking pieces 17, 17.

  As shown in FIGS. 2 and 5, the guide rail 4 is a long member having a substantially U-shaped cross-section with a downward opening and having hanging plates 27, 27 provided from both side edges of the upper plate 26. A pair of sliding pieces 28, 28 projecting from the inner surfaces of 27, 27 across the entire length. Further, as shown in FIG. 4, a guide roller 3 having a vertical rotating shaft 29 protrudes upward from the inside of the groove 20 of the upper frame 12 at the lateral center of the movable panel 1. Is held between both the hanging plates 27, 27 so as to be able to roll above the sliding pieces 28, 28. More specifically, as shown in FIGS. 3 and 4, the rotation shaft 29 of the guide roller 3 can rotate and slide up and down on a hat-type holding base 30 fixed in the recessed groove portion 20 of the upper frame 12. And a compression coil spring 33 is interposed between the locking ring 31 at the lower end of the rotating shaft 29 and the upper surface plate 32 of the holding table 30 so as to face downward with respect to the rising of the rotating shaft 29 and the guide roller 3. It is elastically biased. Further, as shown in FIG. 5, sliders 34, 34 are fitted into engagement grooves 22, 22 formed in both vertical plates 19, 19 of the upper frame 12, and the sliders 34, 34 are attached to the guide rail 4. The movable panel 1 can be smoothly moved by being in sliding contact with the outer surfaces of the both hanging plates 27 and 27.

  Although a guide slider can be used instead of the guide roller 3, it is preferable to use the guide roller 3 in order to move the moving panel 1 smoothly. Further, the sliders 34 and 34 may be provided on the outer surfaces of the both hanging plates 27 and 27 of the guide rail 4 and slidably contact the inner surfaces of both the vertical plates 19 and 19 forming the groove 20. From this point of view, it is preferable to provide the inner surfaces of both vertical plates 19 and 19 as in the present embodiment.

  More specifically, the guide rail 4 is formed of a long aluminum extrusion mold material in which the sliding pieces 28 and 28 are formed at the upper and lower intermediate positions of the both hanging plates 27 and 27, and the direction corresponding to the one side end portion. Both hanging plates 27, 27 below the sliding pieces 28, 28 of the conversion part 4A are cut out to form a notch 35, the moving panel 1 is in a vertical posture and the rolling wheel 2 is in contact with the floor F. In this state, the sliders 34 and 34 of the vertical plates 19 and 19 of the moving panel 1 are in sliding contact with the hanging plates 27 and 27 of the series holding unit 4B and the moving panel is moved from the hanging plates 27 and 27 of the direction changing unit 4A. The height is set so that one vertical plate 19, 19 becomes lower.

  Thereby, when the movable panel 1 is in a vertical posture and the rolling wheel 2 is in contact with the floor surface F, the vertical plates 19 and 19 of the movable panel 1 are placed on the hanging plates 27 and 27 of the series holding portion 4B of the guide rail 4. Since the sliders 34 are in sliding contact with each other, the movable panel 1 can be stably linearly moved along the guide rail 4 without rotating, and the plurality of movable panels 1 can be aligned on a straight line. (See FIG. 1 (a)). Further, in the direction changing portion 4A of the guide rail 4, a notch 35 is formed in the direction changing portion 4A, and the height is set so that the vertical plates 19, 19 of the movable panel 1 are lower than the hanging plates 27, 27. Therefore, the movable panel 1 can be rotated around the vertical rotation axis 29. In this way, in the direction changing portion 4A of the guide rail 4, the movable panels 1,... Can be rotated one after another and overlapped in parallel with each other and stored compactly (see FIG. 1B).

  Here, in order to secure a space for receiving each of the moving panels 1,... In the direction changing part 4 </ b> A at the wall side end of the direction changing part 4 </ b> A of the guide rail 4, An open / close panel 6 that can be rotated horizontally is provided. In the present embodiment, the opening / closing panel 6 is connected to one side end of the movable panel 1 located at the end by a hinge 36 so as to be rotatable. The reason why the open / close panel 6 is hinged to the movable panel 1 located at the end as in the present embodiment is that a plurality of the guide rails 4 are provided in parallel to the ceiling S of the room and the auxiliary guide intersects with them. This is because a rail is provided, and the movable panel 1,... And the opening / closing panel 6 are forwarded to the selected guide rail 4 by using the auxiliary guide rail, so that the compartment size of the indoor space can be adjusted.

  Then, in order to stably maintain the posture of the movable panel 1 moved to a predetermined position, the lift mechanism 5 provided at the lower end of each movable panel 1 is operated to press against the floor surface F, and the rolling wheels 2 are moved to the floor. Lift from surface F. FIG. 5 shows a state in which the movable panel 1 located in the series holding unit 4B is movable, and FIG. 6 shows a state in which the movable panel 1 located in the series holding unit 4B is levitated by the lift mechanism 5, respectively. . 7 and 8 show a state in which the movable panel 1 located in the direction changing portion 4A is movable, and FIGS. 9 and 10 show movement in which the movable panel 1 located in the direction changing portion 4A is levitated by the lift mechanism 5. Each indicates an impossible state.

  Here, even if the movable panel 1 positioned in the direction changing portion 4A is lifted by the lift mechanism 5, the upper ends of the vertical plates 19 and 19 of the upper frame 12 and the notches of the hanging plates 27 and 27 of the guide rail 4 are cut. Since there is a space between it and the portion 35, the closing member 37 is provided in the recessed groove portion 20 of the upper frame 12 so as to be adjustable in height so as to fill this space, and along the both side edges of the upper surface of the closing member 37. Thus, flexible contact members 38 and 38 are provided so as to abut on the lower surfaces of the sliding pieces 28 and 28. The outer surface of the closing member 37 is located on an extension line of the hanging plates 27 and 27 of the direction changing portion 4A and is similar in appearance to the hanging plates 27 and 27 of the series holding portion 4B. The presence of the notch 35 of the guide rail 4 is made inconspicuous.

  Next, an embodiment of the lift mechanism 5 will be described based on FIGS. 4, 5, 10, and 12. In this embodiment, the rolling wheels 2,... Are unitized, and the unit is mounted in the recessed groove portion 20 of the lower frame 13. The unit includes a fixing member 39 having a substantially U-shaped cross-section with a downward opening and a base board member 40 having a substantially U-shaped cross-section with an upward opening, which is fixed in the recessed groove portion 20 of the lower frame 13. It has rolling wheels 2,... Fixed to both ends and the center in the groove 41. The baseboard member 40 has a width that can be inserted into the concave groove 41 of the fixing member 39, and an opening 43 that passes through the rolling wheels 2 is formed on the lower surface 42. And the guide member 44 which formed the inclined guide surface 45 in the lower surface is attached to the right-and-left both ends of the said fixing member 39, and the roller 46 which rolls the said inclined guide surface 45 on the upper surface side of the said baseboard member 40 is attached. A tension coil spring 48 is provided between the fixing member 39 and the baseboard member 40 so as to be elastically biased between the fixing member 39 and the baseboard member 40. . When the fixing member 39 is mounted in the recessed groove portion 20 of the lower frame 13, the rolling wheels 2,... Protrude from the lower end of the panel body 9.

  More specifically, the guide member 44 is a block-like member in which a protrusion 49 is formed at the center of the lower surface and the inclined guide surfaces 45, 45 are formed on both sides thereof. The inclined guide surface 45 has recesses 50 and 50 that engage the roller 46 in a metastable state at the uppermost portion and the lowermost portion, and a continuous inclined curved surface therebetween. The support member 47 is a U-shaped member, and a pair of rollers 46 are provided on both sides thereof. The tension coil spring 48 elastically biases the baseboard member 40 obliquely upward so that the roller 46 engages with the uppermost recess 50. Here, when the baseboard member 40 is in an unloaded state, it is raised by the elastic biasing force of the tension coil spring 48, and the roller 46 is engaged with the uppermost recess 50 of the inclined guide surface 45, and the movable panel 1 is set so that one end of the baseboard member 40 protrudes laterally from a side end on the front side in the moving direction 1.

  As shown in FIG. 12 (a), when the baseboard member 40 is raised, the baseboard member 40 is received in the recessed groove portion 20 of the lower frame 13, and the compatible upper plates 51 and 51 are connected to the vertical frame 11. Are located in the slit grooves 25, 25. Further, the protruding end portion of the baseboard member 40 is provided with a hard synthetic resin contact member 52 whose end shape is the same as the outer shape of the rubber packing 10. Further, the engagement grooves 22 and 22 on the inner surfaces of the lower ends of the vertical plates 19 and 19 of the lower frame 13 are provided with sliders 53 and 53 slidably in contact with the outer surface of the baseboard member 40 to prevent back and forth rattling. Yes.

  And when the said movable panel 1 is moved along the said guide rail 4, and the contact member 52 of the protrusion part of the said baseboard member 40 is made to collide with the side end of the wall surface W or the other preceding movable panel 1, A lateral external force is applied so that the baseboard member 40 is pushed relatively below the panel body 9 by the impact force. Actually, the baseboard member 40 is stopped and restricted in movement, but a relative lateral external force acts by the inertial force of the panel body 9. Accordingly, as the roller 46 rolls down the inclined guide surface 45, the baseboard member 40 descends, and finally reaches the position where it engages with the lowermost recess 50, the baseboard member 40 Is positioned directly below the panel body 9. In other words, the guide member 44 having the inclined guide surface 45 auctions on the stationary roller 46 and the panel body 9 is lifted. As a result, the rolling wheels 2,... Float up and the baseboard member 40 comes into pressure contact with the floor surface F to enter a movement restricted state (see FIG. 12B).

  Here, in the movement restricting state where the baseboard member 40 is pressed against the floor surface F and located immediately below the panel body 9, the roller 46 is engaged in the metastable state with the concave portion 50 at the lowermost portion of the inclined guide surface 45. Furthermore, the elastic biasing force of the tension coil spring 48 acts in the direction in which the panel body 9 is retracted, that is, the concave portion 50 acts in the direction away from the roller 46. Since 40 is only in pressure contact with the floor F, it is difficult to say that it is stable. In particular, since the movable panel 1 located in the direction changing portion 4A is only supported by the guide roller 3 at the center of the upper end, there is a risk of rotating or shifting in the front-rear and left-right directions.

  Accordingly, as shown in FIG. 11, the cross-sectional shape of the rubber packing 10 is devised so that the rubber packings 10, 10 at the side ends of the adjacent moving panels 1, 1 are concavo-convexly fitted. A stopper 8 that engages with the floor surface F is provided at the lower end on the rear side in the movement direction.

  As shown in FIGS. 2 to 4 and 12 to 14, the stopper 8 is made of metal at the lower end of a main body portion 54 made of hard synthetic resin having the same cross-sectional shape as the outer cross-sectional shape of the rubber packing 10. The pins 55 are provided so that the longitudinal grooves 56 formed on both sides of the main body 54 are slidably engaged with the distal bent portions 57 57 of the pair of locking pieces 17 17 of the vertical frame 11. The main body 54 is lowered to drop the pin 55 into an engagement hole 58 formed in advance at a predetermined position on the floor surface F so as to be engaged. Here, the position where the stopper 8 is provided is ensured by shortening the lower end of the rubber packing 10, and when the stopper 8 is raised, the rubber packing 10 comes into contact with the outer appearance.

  Further, the stopper 8 is not lowered by its own weight due to the frictional force between the longitudinal grooves 56, 56 and the bent end portions 57, 57 of the locking pieces 17, 17, but as shown in FIG. A pin 59 may be provided on the upper end of the main body portion 54 so that the pin 59 is fitted into the hollow portion 60 of the rubber packing 10 and held.

  The main body 54 of the stopper 8 of the movable panel 1 arranged in series in advance is in contact with the contact member 52 at the tip of the baseboard member 40 of the subsequent movable panel 1 and the main body 54. Although the contact member 52 is displaced downward with the contact member 52 being in contact with each other, since it is made of a hard synthetic resin and has excellent slidability, a smooth sliding operation can be realized.

  In the case where the movable panel 1 is moved along the guide rail 4 and stored from the state where the rolling base member 40 is pressed against the floor surface F and the rolling wheels 2 are lifted (movement restricted state). First, the stopper 8 is lifted to remove the pin 55 from the engagement hole 58 of the floor F and pull it with the side of the panel main body 9 to disengage the lowermost recess 50 from the roller 46. The panel body 9 is lowered by the weight of the panel body 9 and the rolling wheels 2,...
