Description

  The present invention relates to a moving wall with a door in which a door is rotatably attached to a base frame supported by being suspended by a suspension device that travels on a rail.

In convention halls, banquet halls, conference rooms, training rooms, galleries, art galleries, museums, etc., a wide space is partitioned into a predetermined size by a movable wall that can be manually moved according to the purpose of use. The moving wall is a rectangular plate-like wall body that is suspended and supported by a suspension vehicle that travels while being guided by a rail laid on the ceiling.
Among the moving walls, there is a moving wall with a door in which a rectangular plate-like door is rotatably attached to a base frame that is suspended and supported by a suspension device that travels on a rail (see, for example, Patent Document 1). By installing a moving wall with a door at a predetermined location, the space partitioned by the moving wall can be moved back and forth.

  The movable wall with a door described in Patent Document 1 has an upper member that can be advanced and retracted upward from the upper end of the base frame and a lower member that can be advanced and retracted downward from the lower end of the base frame, and the upper member at a predetermined position. And a fixing mechanism for fixing the base frame by extending the lower member from the base frame and engaging it with the floor. In addition, a lock rod that locks the door in the closed state is provided on the base frame above the door so as to be movable in the vertical direction, and the lock rod extends from the base frame and engages with the door. Locked to the closed state. Furthermore, an interlocking mechanism that interlocks the lock rod and the fixing mechanism is provided. In the interlocking mechanism, when the upper member and the lower member extend from the base frame and the base frame is fixed, the lock rod contracts as the upper member and the lower member move (the length protruding from the base frame becomes shorter). When the locked state of the door is released, and the upper member and the lower member are contracted and the base frame is released, the lock rod extends from the base frame as the upper member and the lower member are moved. Is locked.

  Thereby, when the upper member and the lower member are retracted to the base frame, the lock bar is engaged with the door and the door is locked in the closed state. The door never opens. In order to install the movable wall with a door at a predetermined position, the base frame is fixed by extending the upper member and the lower member from the base frame and engaging the ceiling and the floor after moving to the predetermined position. The At this time, the lock rod contracts with the movement of the upper member and the lower member, and the locked state of the door is automatically released, so that the fixing of the base frame and the unlocking of the door can be performed in one operation. It becomes possible. And in order to move this fixed moving wall with a door to another, the fixation of a base frame is cancelled | released by shrink | contracting the upper member and lower member which were extended from the base frame, respectively. At this time, as the upper member and the lower member move, the lock rod extends and engages with the door, and the door is automatically locked in the closed state. It becomes possible to do it by operation.

Japanese Utility Model Publication No. 3-66376

By the way, in the moving wall with a door described in Patent Document 1, in order to move the moving wall with a door from a state where it is fixed at a predetermined position, the fixing of the base frame is released. Since the door is not fixed when the base frame is released because the release and the door are locked in one operation, the base frame can be released even when the door is not completely closed. For this reason, the door may move when the fixing of the base frame is released, and the door may open before the lock bar engages with the door. As a result, it is impossible to safely release the fixing of the base frame, and if the moving wall with the door is moved in this state, the door moves during the movement, so that the moving wall with the door cannot be moved safely.
In addition, the base frame is fixed after the movement to install the moving wall with the door at a predetermined position. However, in order to perform the fixing of the base frame and the unlocking of the door by one operation, the base frame is fixed. During the fixing operation, the door may be opened before the door is unlocked and the base frame is completely fixed. As a result, when the base frame is completely fixed, the door opens or the base frame is fixed, but when the base frame cannot be fixed, the door is unlocked during this operation and the door opens. Opening and moving walls with doors cannot be installed safely. That is, the safety of the moving wall with the door was not sufficient.
The problem to be solved by the present invention is to provide a movable wall with a door excellent in safety.

  In order to solve the above-mentioned problems, the moving wall with a door according to the present invention is a moving wall with a door in which a door is rotatably attached to a base frame that is suspended and supported by a suspension device that travels on a rail. The frame includes a horizontal frame body that is suspended and supported by the suspension device and extends in the horizontal direction, and a vertical frame body that extends downward from one end of the horizontal frame body, and the vertical frame includes the vertical frame. An upper member that can be advanced and retracted upward from the upper end of the body and a lower member that can be advanced and retracted downward from the lower end of the vertical frame body, and the upper member extends from the vertical frame body at a predetermined position and is engaged with the rail. And a fixing mechanism that extends the lower member from the vertical frame and engages the floor to fix the base frame, and moves the upper member and the lower member to release the fixing. A holding member for releasably engaging the frame with the door and holding the door in a closed state When the door is held closed by the holding member on the base frame, the base frame can be fixed and released by the fixing mechanism, and the base frame is fixed. In the state, when the holding member is locked in the closed state and the base frame is fixed by the fixing mechanism, the holding member holds the door in the closed state and releases the engagement to the door. This is characterized in that an interlocking mechanism is provided which locks the base frame when the door is disengaged by the holding member.

Thus, when the moving wall with the door is moved, the base frame is unlocked. This state is when the door is held in the closed state by the holding member, and at this time, the holding member is locked in the closed state. Therefore, the moving wall with the door can be moved safely without opening the door. Further, when storing the moving wall with the door, it is possible to store the moving wall with the door safely without opening the door by storing in the same state as when moving.
When installing the movable wall with the door at a predetermined position, the base frame is fixed after moving to the predetermined position, but the holding member is locked in the closed state when the base frame is unlocked. Therefore, unless the base frame is fixed, the engagement of the door by the holding member cannot be released. That is, since the door is unlocked after the base frame is fixed, the door is not unlocked and the door is not opened during the operation of fixing the base frame. Moreover, although the operation | movement which fixes a base frame was performed, when a base frame cannot be fixed, a door does not open. Therefore, the movable wall with a door can be installed safely. Further, since the fixing of the base frame is locked when the door is disengaged, the door can be opened and closed safely without the base frame moving.
To move the door-attached moving wall from a fixed state to another position, release the base frame, but the base frame is locked when the door is released from the holding member. Therefore, the base frame cannot be released unless the door is held closed by the holding member. That is, since the fixing of the base frame is released after the door is held in the closed state, the door does not open during the operation of releasing the fixing of the base frame. Therefore, the base frame can be safely released.
Therefore, the movable wall with a door according to the present invention is excellent in safety.

  Hereinafter, one embodiment of a moving wall with a door concerning the present invention is described based on an accompanying drawing. As shown in FIG. 1, the movable wall 1 with a door according to the present embodiment is provided so as to be able to go back and forth between the spaces partitioned by the movable wall 15 by being installed at a predetermined location. Similarly to the moving wall 15, the moving wall 1 with a door is provided with a suspension device 11 at the upper end in the vicinity of both sides in the width direction so that it can be manually moved along the rail 12 together with the two suspension devices 11. It has become. The rail 12 is formed with a basic shape having a slit having an opening at the center of the lower side of a substantially rectangular cylinder having a horizontally long cross section. The vehicle body provided with the wheel which is the main component of the suspension apparatus 11 travels in the rail 12. A moving wall 1 with a door is attached to a connecting portion 11 a (see FIG. 3) that extends downward from the lower surface of the vehicle body through a slit of the rail 12, and the moving wall 1 with a door is suspended and supported by the suspension device 11. . In addition, in FIG. 1, the code | symbol 16 has shown the moving wall with a door different from the moving wall 1 with a door of this embodiment arrange | positioned at the both sides or one side when partitioning with the some moving wall 15. FIG.

  The movable wall 1 with a door is attached to a connecting portion 11 a of a suspension device 11 that travels on a rail 12 and is supported by being suspended by the suspension device 11, and a door 3 that is rotatably attached to the base frame 2. And.

  As shown in FIG. 2, the base frame 2 includes a horizontal frame body 21 that is suspended and supported by the suspension device 11 and extends in the horizontal direction, a vertical frame body 22 that extends downward from one end of the horizontal frame body 21, and a vertical frame body 22. It has a receiving portion 23 that protrudes from the lower end of the frame body 22 toward the horizontal frame body 21 side. Although the base frame 2 has the receiving part 23, it is formed in the substantially L shape by the horizontal frame 21 and the vertical frame 22 as a whole. The base frame 2 is preferably formed so that the length in the height direction of the horizontal frame body 21 and the width (length in the horizontal direction) of the vertical frame body 22 are as short as possible so that the ratio of the door 3 is increased. Therefore, as shown in FIGS. 4, 5, 10 and 11, the base frame 2 has a pair of reinforcing plates 27 between the pair of surface panels 24 and the block body 25 (including the interior body 26). It is provided. The pair of surface panels 24, the pair of reinforcing plates 27, and the block body 25 are fixed to each other by screwing. In the corners of the base frame 2, on the extension line of the inner surface of the vertical frame body 22, that is, in the vicinity of one end portion of the horizontal frame body 21 and in the vicinity of the tip end portion that is the other end portion of the horizontal frame body 21. The suspension vehicle attachment members 18 for attaching the connecting portions 11a are fixed.

  Since the shape of the two suspension vehicle attachment members 18 and the structure of the horizontal frame body 21 to which the suspension vehicle attachment member 18 is fixed are substantially the same, only the corner side of the base frame 2 will be described, and the tip of the horizontal frame body 21 will be described. The explanation on the part side is omitted. The suspension vehicle attachment member 18 is formed in an elongated flat rectangular parallelepiped shape extending in the longitudinal direction of the horizontal frame body 21, and penetrates in the thickness direction (vertical direction) in the center portion, and the connection portion 11 a of the suspension vehicle device 11 is screwed together. A screw hole 18a is provided (see particularly FIG. 5). On both end surfaces (surfaces on both sides in the thickness direction of the door 3) extending in the longitudinal direction of the suspension vehicle mounting member 18, convex portions 18 b that protrude from the surfaces in a rectangular shape are provided. These two convex portions 18b are fitted and fixed to the fitting portions 27a of the pair of reinforcing plates 27, respectively. The portion where the suspension wheel mounting member 18 is fixed to the pair of reinforcing plates 27 is a portion where the upper portion is open and the lower portion is provided with a space between the block body 25 (in the illustrated example, a lock bar described later). 103 includes a portion where a rectangular hole 103a into which the lower portion of the connecting portion 11a can be inserted is provided. For this reason, the upper end near the both sides in the width direction of the movable wall 1 with the door by screwing the connecting portion 11a of the suspension device 11 from above into the screw holes 18a of the suspension vehicle mounting member 18 fixed to the pair of reinforcing plates 27. Are suspended and supported by the suspended vehicle device 11 at each of the two locations. Moreover, the position of the height direction (up-and-down) of the moving wall 1 with a door with respect to the connection part 11a of the suspension vehicle apparatus 11 is moved up and down by moving the screwing part of the connection part 11a of the suspension apparatus 11 to the suspension vehicle attachment member 18 up and down. Adjustment can be made. In FIG. 5, reference numeral 27 b denotes a protruding piece 103 b that is formed by protruding both side portions in the width direction of the portion where the hole 103 a of the lock bar 103 is provided so as to be slidable in the longitudinal direction of the lock bar 103. A recess is shown. The recess 27b acts as a guide for moving the lock bar 103 in the longitudinal direction.

  As shown in FIGS. 1 to 3, the door 3 is formed in a rectangular flat plate shape that is substantially the same as or slightly smaller than the rectangular shape of the width and height of the L-shaped inner side of the base frame 2. The door 3 is not particularly limited, but is preferably a glass door. The door 3 is formed, for example, by fitting the upper and lower sides of a rectangular flat glass plate 30 to upper and lower frames 31 and 32 having a concave cross section. The upper and lower frames 31 and 32 are paired between the pair of surface panels 33 and the block body 34 (see FIG. 6) or the interior body so that the length in the height direction is as short as possible, like the base frame 2. A reinforcing plate 35 is provided and formed. Thereby, since most of the doors 3 are the glass plates 30, they look good. Upper and lower frames 31 and 32, that is, a door 3 is rotatably attached to the base frame 2 via upper and lower rotary shafts 4 and 5. The door 3 may be rotatably attached to the base frame 2 using a hinge, but is preferably attached rotatably via the upper and lower rotating shafts 4 and 5. Moreover, in FIG.1 and FIG.2, the code | symbol 39 has shown the handle.

  As shown in FIGS. 3 to 5, the first rotating shaft 4 that is the upper rotating shaft is supported by being suspended in a rotatable manner within the horizontal frame body 21, and the lower portion is attached to the door 3. The first rotating shaft 4 is a screw member having a head 4a, for example, a hexagonal head 4a, and is a portion where the head 4a and the upper part are positioned in the horizontal frame 21, and from the horizontal frame 21 A thread groove is formed at the protruding portion to form a threaded portion 4b. The screw part 4 b may be formed on the upper part of the first rotating shaft 4. The upper portion of the first rotation shaft 4 is supported by the first rotation shaft support portion 41 of the horizontal frame body 21. The first rotating shaft support portion 41 is between the fixed portions to which the two suspension vehicle attachment members 18 of the horizontal frame body 21 are fixed, and in the vicinity of the fixed portion on the vertical frame body 22 side (corner side of the base frame 2). It is preferable to be provided. That is, it is preferable that the 1st rotating shaft 4 is arrange | positioned at the horizontal frame 21 of the vicinity of the suspension vehicle attachment member 18 by the side of the vertical frame 22.

  The first rotating shaft support portion 41 is formed by the block body 25 and a pair of reinforcing plates 27. That is, the block body 25 constituting the horizontal frame body 21 is composed of two block bodies 25 that are divided in the horizontal direction. The first rotating shaft 4 is fitted between the two block bodies 25 so as to be inserted from above. The upper surfaces of the two block bodies 25 facing each other are recessed on the stairs to form step portions 42 (see particularly FIG. 4). Rectangular holes 43a are respectively provided in the space where these stepped portions 42 are formed and the pair of reinforcing plates 27 corresponding to the space between these spaces (see particularly FIG. 5). The bottom surface for forming these holes 43 a is formed flush with the stepped portion 42 of the block body 25. The holes 43a of the pair of reinforcing plates 27 are substantially L-shaped, with rectangular holes 43a extending upward to, for example, double the height, and extending in the longitudinal direction of the horizontal frame 21 opposite to the vertical frame 22. Is formed. A first rotating shaft support portion 41 is formed by the L-shaped hole 43 of the pair of reinforcing plates 27 and the stepped portion 42 of the block body 25.

  A rectangular flat plate-shaped receiving plate 44 is placed on the bottom surface forming the stepped portions 42 of the two block bodies 25 and the holes 43 of the pair of reinforcing plates 27 (actually, the rectangular holes 43a). The receiving plate 44 is formed so that the length in the thickness direction of the reinforcing plate 27 is substantially the same as the length between the outer surfaces of the pair of reinforcing plates 27, and in the longitudinal direction of the horizontal frame body 21. The length is formed by a dimension slightly shorter than the length between the vertical surfaces formed by the step portions 42 of the two block bodies 25 and facing each other. Further, a screw portion 4b of the first rotating shaft 4 is inserted in the center portion of the receiving plate 44, and a hole having a diameter slightly larger than that of the screw portion 4b is provided. Accordingly, the receiving plate 44 is placed in a state of being fitted onto the bottom surfaces forming the step portions 42 of the two block bodies 25 and the holes 43 of the pair of reinforcing plates 27. The head 4 a of the first rotary shaft 4 is placed on the receiving plate 44 via a ring-shaped bearing 45. That is, the ring-shaped bearing 45 and the receiving plate 44 are sequentially passed from the front end of the first rotating shaft 4 to the outer periphery of the screw portion 4b, and the front end is inserted between the two block bodies 25 from above to be removed from the horizontal frame body 21. By projecting downward and placing the receiving plate 44 in a state of being fitted on the bottom surfaces forming the stepped portions 42 of the two block bodies 25 and the holes 43 of the pair of reinforcing plates 27, the receiving plate 44 is placed. The head portion 4a is placed on the ring-shaped bearing 45 above. As a result, the first rotating shaft 4 is suspended and supported by the horizontal frame 21 so that the position with respect to the horizontal frame 21 is not displaced, and the first rotating shaft 4 is supported by the screw portion 4b of the first rotating shaft 4. By attaching the door 3, the upper part of the door 3 is suspended and supported by the first rotation shaft 4 so as to be rotatable.

  Although attachment to the door 3 of the 1st rotating shaft 4 will not be specifically limited if it can attach to the door 3, It is preferable to be able to adjust the attachment position of the door 3 with respect to the 1st rotating shaft 4, for example, FIG. As shown in FIGS. 4 to 6, it is preferable to use a hinge nut 46 that engages with the door 3 and is screwed to the first rotating shaft 4, and a nut 47 that is screwed to the first rotating shaft 4.

  The hinge nut 46 is formed in a rectangular flat plate shape, and a screw hole 46a into which the first rotating shaft 4 is screwed is provided at the center. The length in the thickness direction of the door 3 of the hinge nut 46 is formed with substantially the same dimension as the length between the surfaces that are the outer surfaces of the pair of reinforcing plates 35 of the upper frame 31. The length in the width direction of the door 3 of the hinge nut 46 is the length in the longitudinal direction of the rectangular slide hole 36 elongated in the width direction of the door 3 provided to face the pair of reinforcing plates 35 of the upper frame 31. It is formed shorter than this. The thickness of the hinge nut 46 is formed to be slightly shorter than the length of the slide hole 36 in the height direction. Thereby, the hinge nut 46 is engaged with the slide holes 36 of the pair of reinforcing plates 35 of the upper frame 31 so as to be slidable in the longitudinal direction of the slide holes 36.

  The nut 47 is not particularly limited, and for example, a hex nut is used. After the nut 47 is screwed into the threaded portion 4 b of the first rotating shaft 4, the tip of the first rotating shaft 4 is inserted into a shaft hole 61 a of the first slide member 61 described later, and a pair of reinforcing plates 35 of the upper frame 31. The upper nut 31 and the first slide member 61 are fastened with the hinge nut 46 and the nut 47 so that the door 3 is attached to the first rotating shaft 4. The upper end in the vicinity of one corner is fixed. Further, when the upper frame 31 and the first slide member 61 are fastened by the hinge nut 46 and the nut 47, the screwing position of the hinge nut 46 and the nut 47 with respect to the first rotating shaft 4 is moved up and down, thereby The position of the door 3 in the height direction (up and down) with respect to the rotating shaft 4 can be adjusted.

  Moreover, it is preferable that the door 3, that is, the upper frame 31, is provided with the first shaft adjusting portion 6 that adjusts the position of the first rotating shaft 4 in the width direction of the door 3. The first axis adjusting unit 6 includes a first slide member 61 provided on the upper frame 31 so as to be slidable in the width direction of the door 3, and a first adjuster member that slides the first slide member 61. The first slide member 61 is formed in an elongated flat rectangular parallelepiped shape extending in the width direction of the door 3. The length in the thickness direction of the door 3 of the first slide member 61 is formed to have substantially the same dimension as the length between the surfaces that are the outer surfaces of the pair of reinforcing plates 35 of the upper frame 31. The first slide member 61 is placed on the upper end surfaces of the pair of reinforcing plates 35 of the upper frame 31. A shaft hole 61 a penetrating in the up-down direction in which the first rotating shaft 4 is inserted is provided on the end portion side on the horizontal frame body 21 side which is one end portion of the first slide member 61. The diameter of the shaft hole 61 a is formed to be slightly larger than the diameter of the screw portion 4 b of the first rotating shaft 4. At the center in the longitudinal direction of the first slide member 61 and the other end side, elongated holes 61b penetrating in the vertical direction and extending in the longitudinal direction are provided. A slide bolt 62, which is a first fixing member having a head, is inserted into each elongated hole 61b from above, and these slide bolts 62 are provided in two screw holes 34a provided in the block body 34 of the upper frame 31. Are screwed together. Accordingly, the first slide member 61 is fixed to the upper frame 31 of the door 3 by the head of the slide bolt 62 and the block body 25 by rotating the slide bolt 62 in the tightening direction with respect to the screw hole 34a. It has become. In addition, the slide bolt 62 is rotated in the direction in which the slide bolt 62 is detached from the screw hole 34a within a range in which the slide bolt 62 is not detached from the screw hole 34a, and the head of the slide bolt 62 and the block body 34 are not tightened. By setting the state, the first slide member 61 can slide in the width direction of the door 3.

  The first adjuster member is, for example, the first adjustment screw 63. On the end surface of the first slide member 61 opposite to the horizontal frame body 21 (on the opposite side to the first corner portion, which is a corner portion near the horizontal frame body 21 above the door 3), A screw hole 61c that extends in the longitudinal direction and penetrates through the long hole 61b (the long hole 61b on the end portion side) and is screwed with the first adjustment screw 63 is provided. The first adjustment screw 63 is screwed into the screw hole 61c so that the tip of the first adjustment screw 63 comes into contact with the slide bolt 62 inserted into the elongated hole 61b. As a result, in a state where the two slide bolts 62 are loosened, the first adjustment screw 63 is rotated with respect to the screw hole 61c so that the length of the first adjustment screw 63 protruding from the long hole 61b is increased. The position of the first rotating shaft 4 in the width direction with respect to the door 3 slides in the second width direction (the width direction from the first corner of the door 3 to the second corner opposite to the first corner). It moves in two width directions. Conversely, by rotating the first adjusting screw 63 with respect to the screw hole 61c so that the length protruding from the long hole 61b is shortened, the first slide member 61 is moved in the second width direction by the weight of the door 3. It slides in the 1st width direction of the opposite direction, and the position of the width direction with respect to the door 3 of the 1st rotating shaft 4 moves to a 1st width direction. Therefore, the position of the first rotating shaft 4 in the width direction with respect to the door 3 can be adjusted by rotating the first adjusting screw 63 with respect to the screw hole 61c. The slide range of the first slide member 61, which is the range of movement in the width direction of the first rotating shaft 4 with respect to the door 3, is the range in which the slide bolt 62 can move through the long hole 61b or the hinge nut 46 moves through the slide hole 36. Since this is the range to be obtained, the slide range of the first slide member 61 can be adjusted by adjusting the lengths of the long holes 61b and the slide holes 36 in the longitudinal direction.

  As shown in FIG. 7, the second rotating shaft 5, which is a lower rotating shaft, is attached to the receiving portion 23 of the base frame 2 so that the lower portion of the door 3 can rotate. The 2nd rotating shaft 5 is formed in the column shape. The second rotating shaft 5 may be attached in the vicinity of the lower corner portion of the lower end of the door 3 on the first corner portion side, but is preferably attached to the receiving portion 23. The receiving portion 23 is formed, for example, in a substantially rectangular shape in cross section that protrudes in parallel with the horizontal frame body 21 from the lower end of the vertical frame body 22 toward the horizontal frame body 21 side. Although the protrusion length of the receiving part 23 is arbitrarily set from the range in which the 2nd rotating shaft 5 can be attached, it is preferable to form in the dimension as short as possible. The second rotating shaft 5 is fixed and attached to the receiving portion 23 so that the shaft is parallel to the vertical direction of the door 3 and protrudes upward from the upper surface of the receiving portion 23.

Upper and lower connecting pins 285a and 285b are provided at the upper and lower ends of the rack member 283, respectively. These upper and lower connecting pins 285a and 285b are respectively inserted into two guide holes 286a and 286b provided in the vertical frame 22 so as to extend in the vertical direction. As a result, the rack member 283 moves in the vertical direction within a range in which the upper and lower connecting pins 285a and 285b are guided in the vertical direction in the guide holes 286a and 286b, respectively. The upper and lower connecting pins 285a and 285b are positioned at the bottom of the guide holes 286a and 286b when the pressing bar 83 and the moving bar 82 are positioned at the retracted position, and the pressing bar 83 and the moving bar 82 are fixed positions. The positions and lengths of the guide holes 286a and 286b are set so that the guide holes 286a and 286b are positioned at the top of the guide holes 286a and 286b.

  The lower end of the upper interlocking bar 287 is attached to the upper connecting pin 285a. The upper interlocking bar 287 is connected to the lower end of the press contact bar 83 through one or more connecting bars 288. The upper interlocking bar 287 and the connecting bar 288 are provided on the vertical frame 22 so as to be movable in the vertical direction. When the upper connecting pin 285a moves in the vertical direction, the upper interlocking bar 287 and the upper connecting bar 288 are moved. The pressure contact bar 83 moves up and down. The connection between the upper interlocking bar 287 and the connecting bar 288, the connection between the connecting bars 288, and the connection between the connecting bar 288 and the press-contact bar 83 are connected to each other using a connecting pin, and these can be rotated. The connecting pins are respectively inserted into the guide holes, and the movement of the upper interlocking bar 287 and the connecting bar 288 in the vertical direction of the vertical frame body 22 is guided by the guide holes.

  The upper end of the first lower interlocking bar 381 is attached to the lower connecting pin 285b. The lower end of the first lower interlocking bar 381 is connected to the first side 382a of the direction changing bar 382. The direction changing bar 382 converts the vertical movement in the opposite direction, is formed in a bent shape, and is rotatably attached to the vertical frame body 22 with a corner portion formed by being bent as an axis. The direction changing bar 382 is arranged such that two sides are directed downward when the lower connecting pin 285b is positioned at the bottom of the guide hole 286b (see particularly FIG. 13). The lower end of the first lower interlocking bar 381 is connected to one first side 382a of the direction change bar 382, in the illustrated example, the tip of the left side, and the other second side 382b, the tip of the right side in the illustrated example. The upper end of the second lower interlocking bar 383 is connected to the part. Further, the direction changing bar 382 rotates clockwise in the illustrated example when the lower connecting pin 285b moves from the bottom of the guide hole 286b to the top, and the tip of the first side 382a becomes an arc shape in the illustrated example. Moves upward and is positioned above the rotation axis of the direction change bar 382, and the tip of the second side 382b moves downward in an arc shape and moves vertically below the rotation axis of the direction change bar 382. (That is, it is formed so as to stop when the tip of the second side 382b slightly exceeds the lowermost (lowermost) position in the vertical direction) (see particularly FIGS. 14 and 15). The movement of the first side 382a and the second side 382b is performed by the connecting pins 386a and 386b being guided by the guide holes 385a and 385b. Thus, when the lower connecting pin 285b moves from the bottom to the top of the guide hole 286b, the direction change bar 382 rotates and is connected to the tip of the second side 382b. The bar 383 moves downward.

  The second lower interlocking bar 383 is connected to the upper end of the moving bar 82 via one or more connecting bars 384 provided on the vertical frame 22 so as to be movable in the vertical direction, and the lower connecting pin 285b. Is moved in the vertical direction, the moving bar 82 is moved in the vertical direction opposite to the connecting pin 285b through the first lower interlocking bar 381, the direction changing bar 382, the second lower interlocking bar 383, and the connecting bar 384. It has become. Thus, an operation jig such as a tool is fitted and inserted into the operation hole 284 to rotate the pinion 282, and guide the upper and lower connecting pins 285a and 285b positioned at the bottom of the guide holes 286a and 286b. When moved to the top of the holes 286a and 286b, the pressure contact bar 83 and the moving bar 82 are interlocked to move the pressure contact bar 83 from the retracted position to the fixed position, and the moving bar 82 moves from the retracted position to the engaged position. It is supposed to be. Further, when the pinion 282 is rotated by the operation jig and the upper and lower connecting pins 285a and 285b positioned at the top of the guide holes 286a and 286b are moved to the bottom of the guide holes 286a and 286b, the pressure contact bar 83 and the moving bar 82 are interlocked so that the pressure contact bar 83 moves from the fixed position to the retracted position, and the moving bar 82 moves from the engaging position to the retracted position. The connection between the second lower interlocking bar 383 and the connection bar 384, the connection between the connection bars 384, and the connection between the connection bar 384 and the moving bar 82 are connected to each other using connection pins, respectively, and These connecting pins are inserted into the guide holes, respectively, and the movement of the second lower interlocking bar 383 and the connecting bar 384 in the vertical direction of the vertical frame body 22 is guided by the guide holes.

  The connecting bar 384 that connects the second lower interlocking bar 383 and the moving bar 82 is provided with a biasing means that biases the connecting bar 384 upward. The biasing means is, for example, a coil-shaped biasing spring 387. The urging spring 387 is mounted so as to be wound around the outer periphery of the connecting bar 384, one end abuts on a receiving seat 388 fixed to the vertical frame body 22, and the other end is fixed to the connecting bar 384. The connection bar 384 is always urged upward by contacting the contact seat 389. As a result, the direction of the direction change bar 382 that is biased changes when the tip of the second side 382b is positioned at the lowest position. That is, the tip of the second side 382b on the side different from the side where the tip of the first side 382a is located, with the border surface being a vertical surface including the rotation axis of the direction change bar 382 as a boundary, in the illustrated example, from the lowest position to the right Is positioned so that the tip of the second side 382b rotates counterclockwise in the illustrated example, that is, the tip of the first side 382a is biased to move downward. Thus, when the pressure contact bar 83 and the moving bar 82 are respectively positioned at the retracted position, they are respectively held at the retracted position by the biasing force of the biasing spring 387 (see FIG. 13). Conversely, when the tip of the second side 382b is located on the same side as the tip of the first side 382a with respect to the boundary surface, in the illustrated example, on the left side from the lowest position, the second side 382b is rotated clockwise in the illustrated example. The tip of the side 382b is biased to rotate, that is, the tip of the first side 382a is biased to move upward, so that the pressure contact bar 83 and the moving bar 82 are moved to the fixed position and the engagement position. When positioned, they are held in the fixed position and the engaged position by the biasing force of the biasing spring 387 (see FIGS. 14 and 15). That is, a holding mechanism that includes the direction changing bar 382 and the urging spring 387 that is urging means and holds the pressure contact bar 83 and the moving bar 82 in the fixed position, the engagement position, or the retracted position is configured.

  In addition, the movement range of the tip of the second side 382b of the direction change bar 382 is almost on the right side of the boundary surface, and is less on the left side of the boundary surface. The range on the left side includes a case where the press contact bar 83 and the moving bar 82 are located at the fixed position and the engagement position, or a case immediately before being located at these positions. For this reason, the pressure contact bar 83 and the moving bar 82 extend from the vertical frame body 22 respectively, and the positioning pin 85 of the pressure contact plate 84 of the pressure contact bar 83 engages with the engagement hole 14a of the pin receiving plate 14 attached to the rail 12. Further, the pressure contact plate 84 comes into surface contact with the pin receiving plate 14 so that the upper portion of the base frame 2 is fixed to the rail 12, and the engagement protrusion 82 a of the moving bar 82 is inserted into the engagement hole 19 a of the floor 19. Thus, the lower part of the base frame 2 (vertical frame body 22) is positioned on the floor 19 and is fixed with its movement suppressed, that is, the press contact bar 83 and the moving bar 82 are completely fixed and engaged. If the base frame 2 is not fixed and is not fixed, the position of the tip of the second side 382b of the direction changing bar 382 is on the right side of the boundary surface, and the base frame 2 is not completely fixed. Operation jig When the operation is stopped and the force on the pinion 282 and the rack member 283 is released, the urging force of the urging spring 387 causes the direction changing bar 382 to rotate counterclockwise, so that the pressure contact bar 83 and the moving bar 82 are in the retracted position, respectively. It is supposed to be located in. Thereby, it can be easily grasped whether or not the base frame 2 is fixed.

  Further, as shown in FIGS. 3 and 10 to 15, the horizontal frame body 21 is rotatably provided with a holding member 9 that holds the door 3 in a closed state so that the door 3 can be released. The holding member 9 is preferably a hanging member that suspends and supports the door 3 when the door 3 is held in the closed state. That is, the holding member 9 suspends and supports the door 3 and holds it in the closed state. The holding member 9 is engaged with a support pin 90 attached to the door 3 to suspend and support the door 3, and a release position where the engagement with the support pin 90 is released and the door 3 can be opened and closed. Is provided on the horizontal frame 21 so as to be rotatable between the two. It is preferable that the holding member 9 is provided in the vicinity of the fixed portion on the second corner portion side of the door 3 between the fixed portions to which the two suspension vehicle mounting members 18 are fixed. That is, it is preferable that the holding member 9 is disposed at a position of the horizontal frame 21 in the vicinity of the suspension vehicle mounting member 18 on the side away from the vertical frame 22.

  The holding member 9 is formed in a substantially rectangular flat plate shape close to a substantially rectangular parallelepiped shape extending in the height direction. The upper end portion of the holding member 9 is a base portion, and a shaft hole 9c into which a rotating member 91 that rotatably supports the holding member 9 is inserted and engaged is provided in the base portion. Further, the vertical frame body 22 side of the upper end surface of the holding member 9 is formed as a stepped portion 93 that is recessed downward. A notch 95 extending in the horizontal direction is provided near the lower end portion of the side surface of the holding member 9 on the second corner portion side, and the lower end portion of the holding member 9 is formed as a hook portion 94. On the back side of the notch 95 forming the hook portion 94, a recess 95a wider than the opening is formed. Thereby, when the support pin 90 is inserted into the notch 95 of the hook portion 94, that is, when the hook portion 94 is engaged with the support pin 90, the recess 95 a is formed in the notch 95. Since the support pin 90 is difficult to be removed from the notch 95, the engagement of the hook portion 94 with the support pin 90 can be maintained. Further, the opening side of the hook portion 94 on the tip surface that is the lower end surface of the holding member 9 is formed as a stepped portion 96 that is depressed.

  The holding member 9 is preferably formed by superimposing the two suspension plates 9a and 9b and fixing them with, for example, two screws. In this case, a slit 9d extending in the width direction from one side surface is formed in one suspension plate 9a, and a slit 9e extending in the width direction from the other side surface is formed in the other suspension plate 9b. When the plates 9a and 9b are overlapped, the shaft hole 9c is formed by both the slits 9d and 9e. The rotating member 91 inserted into the shaft hole 9c is formed in a columnar shape. Engaging portions 91 a parallel to each other are provided at locations corresponding to the shaft holes 9 c of the rotating member 91.

The fixing member 191 is attached while being sandwiched between the pair of reinforcing plates 35 of the upper frame 31.

  The upper portion of the pair of reinforcing plates 35 positioned below the holding member 9 is recessed in a long and narrow rectangular shape in the width direction of the door 3, and the lower portion on the side of the horizontal frame body 21 is recessed in the horizontal direction to the back. A substantially L-shaped fitting recess 193 formed as the recess 193a is provided. The length in the width direction of the portion where the restriction recess 193a of the fitting recess 193 is not provided is formed to be slightly longer than the length in the width direction of the mounting portion 191a of the fixing member 191. Further, the length in the height direction of the fitting recess 193 is formed to be shorter than the length in the height direction of the support portion 191 b of the fixing member 191. Below the fitting recess 193 of one of the reinforcing plates 35, two holes 194a are provided corresponding to the through holes 191c of the mounting portion 191a of the fixing member 191. It has been. Screw holes 194b into which mounting screws are respectively screwed are provided at locations corresponding to the through holes 191c of the mounting portion 191a of the fixing member 191 of the other reinforcing plate 35. The fixing member 191 is clamped between the pair of reinforcing plates 35 of the upper frame 31 by using mounting screws in a state where the holes 194 a and the screw holes 194 of the pair of reinforcing plates 35 are aligned with the through holes 191 c of the fixing member 191. The supporting portion 191b of the fixing member 191 is positioned between the fitting recesses 193 of the pair of reinforcing plates 35, and the upper surface of the supporting portion 191b is positioned above the upper end surface of the reinforcing plate 35. It is formed as follows.

  The moving member is formed by a pair of moving plates 192 that are respectively fitted in the fitting recesses of the pair of reinforcing plates 35. The pair of moving plates 192 are formed in a substantially L-shaped plate shape in which the upper end surface on the side of the vertical frame body 22 in the shape of a rectangular flat plate elongated in the width direction of the door 3 is protruded upward and formed as a pin mounting portion 192a. Yes. The thickness of the moving plate 192 is formed with substantially the same dimension as the thickness of the reinforcing plate 35. The length in the height direction of the portion where the pin mounting portion 192a of the moving plate 192 is not provided is longer than the length in the height direction of the fitting recess 193 and in the height direction of the support portion 191b of the fixed member 191. The dimension is shorter than the length. The length in the width direction of the moving plate 192 is formed to be slightly shorter than the length in the width direction of the fitting recess 193 at a location where the limiting recess 193 a is not provided. The moving plate 192 fits in the fitting recess 193. It is supposed to be combined.

  On the lower part of the end surface on the pin mounting portion 192a side of the moving plate 192, a convex portion 192b that protrudes in a rectangular shape in the width direction and is positioned in the limiting concave portion 193a when fitted to the fitting concave portion 193 is provided. The protruding length of the convex portion 192b, that is, the length in the width direction of the moving plate 192 where the convex portion 192b is provided is greater than the length in the width direction of the fitting concave portion 193 where the limiting concave portion 193a is provided. It is formed with slightly short dimensions. The length of the convex portion 192b in the height direction is shorter than the length of the limiting concave portion 193a in the height direction. Thereby, when the moving plate 192 is fitted to the fitting recess 193, the movement of the moving plate 192 on the pin mounting portion 192a side of the moving plate 192 in the height direction is such that the convex portion 192b moves up and down within the limiting concave portion 193a. It is performed within the range that can move.

  Two holes 192c are provided at positions corresponding to the long holes 191d of the fixed member 191 of the one moving plate 192 to pass the adjusting screw and accommodate the head of the adjusting screw. In addition, two screw holes 192d into which adjustment screws are screwed are provided at positions corresponding to the long holes 191d of the fixing member 191 of the other moving plate 192. As a result, when the moving plate 192 is fitted in the fitting recess 193, the moving plate 192 on the side where the pin mounting portion 192a of the moving plate 192 is not provided is moved in the height direction by adjusting the adjustment screw with the long hole 191d. Is performed in a range that can move up and down. This moving range is preferably formed so that the convex portion 192b of the moving plate 192 is substantially the same as the range in which the convex portion 192b can move up and down within the limiting concave portion 193a. Therefore, the movable plate 192 is provided so as to be movable in the vertical direction. This movement is within a range in which the adjustment screw can move in the long hole 191d or a range in which the convex portion 192b of the movable plate 192 can move in the limiting concave portion 193a. Therefore, the range of movement up and down of the moving plate 192 can be adjusted by adjusting the length of the long hole 191d, the convex portion 192b of the moving plate 192, and the limiting concave portion 193a.

  In addition, a holding plate 195 is attached to the upper surface of the support portion 191b of the fixing member 191 in a surface contact state with an attachment bolt 196.

In this state, the holding member 9 can hold the door 3 in the closed state and release the engagement with the door. When the door is released from the holding member 9, the base frame 2 is locked. It is configured to be. That is, when the door 3 is held in the closed state by the holding member 9, the interlocking mechanism 10 can fix the base frame 2 by the fixing mechanism 8 and release the fixing, but the base frame 2 is released from the fixing state. In this state, since the holding member 9 is locked in the closed state, the door 3 cannot be unlocked until the base frame 2 is fixed. Further, when the base frame 2 is fixed, the interlocking mechanism 10 can hold the door 3 in the closed state by the holding member 9 and release the engagement with the door 3, and the engagement of the door 3 by the holding member 9. Since the fixing of the base frame 2 is locked in the released state, the fixing of the base frame 2 can be performed only after the door 3 is held in the closed state.

  The interlocking mechanism 10 is provided on the horizontal frame 21 so as to be rotatable between a first lock position that locks the holding member 9 in the engagement position and a second lock position that locks the pressure contact bar 83 in the fixed position. 101 is provided on the horizontal frame 21 so as to be rotatable between a first position allowing the movement of the pressure contact bar 83 from the retracted position to the fixed position and a second position locking the pressure contact bar 83 at the fixed position.

An end portion in the width direction opposite to the horizontal frame body 21 of the lock cam 101 is rotatably attached to the horizontal frame body 21 via a rotation shaft 101a. From the position below the rotation shaft 101 a of the lock cam 101 to the first surface 105 a that is the lower surface of the cam portion 105, a shape that can come into surface contact with the upper end surface of the holding member 9 is formed. That is, the first surface 105 a of the cam portion 105 of the lock cam 101 is in contact with the step portion 93 on the upper end surface of the holding member 9. The boundary between the end surface of the lock cam 101 on the side of the horizontal frame 21 and the cam portion 105 is formed as a cam surface 105 b parallel to the width direction of the door 3. The second surface 105c, which is the remaining surface other than the first surface 105a of the cam portion 105, is inclined so as to be a vertical surface parallel to the height direction when the lock cam 101 is in the second lock position. When the holding member 9 is positioned at the engagement position, the lock cam 101 has a longitudinal direction substantially parallel to the width direction of the door 3, a part of the lower surface and the first surface 105 a of the cam portion 105 on the upper surface of the holding member 9. It is located in the 1st lock position for contacting and locking the holding member 9 in an engagement position. When the holding member 9 is rotated from the engagement position to the release position, the lock cam 101 rotates from the first lock position to the second lock position as the holding member 9 rotates. That is, when the holding member 9 is rotated from the engagement position to the release position, first, the first surface 105a of the cam portion 105 of the lock cam 101 is pushed up by the stepped portion 93 on the upper end surface of the holding member 9 to rotate the lock cam 101. Then, when the location where the first surface 105a of the holding member 9 is pushed up moves from the stepped portion to the side end surface and the holding member 9 rotates about 90 ° and is accommodated in the upper frame 31 to reach the release position, the rotation of the lock cam 101 is performed. Stops. This stop position is the second lock position for locking the pressure contact bar 83 to the fixed position. Further, when the holding member 9 is rotated from the release position to the engagement position, the lock cam 101 rotates by its own weight from the second lock position to the first lock position and returns naturally.

  The link cam 102 is provided between a fixing portion where the suspension wheel mounting member 18 is fixed in the vicinity of the corner of the base frame 2 and the engagement piece 86 of the press contact bar 83. The link cam 102 extends in the vertical direction, and the upper part is rotatably attached to the base frame 2 via a rotation shaft. A lower portion of the side surface of the link cam 102 on the side where the suspension vehicle mounting member 18 is fixed is formed as an abutting portion 102a with which the lock bar 103 abuts. Further, below the side surface of the link cam 102 on the side opposite to the contact portion 102a, a cam portion 106 that protrudes in a substantially rectangular shape obliquely downward is provided when the pressure contact bar 83 is located at the retracted position. . The leading end surface of the cam portion 106 is formed as a first surface 106a, and the upper surface of the cam portion 106 is formed as a second surface 106b. The link cam 102 has a first position in which the first surface 106a of the cam portion 106 is in contact with the distal end surface of the engagement piece 86 of the press contact bar 83 and allows the press contact bar 83 to move from the retracted position to the fixed position. When the 83 is moved from the retracted position to the fixed position, the lower surface of the engagement bar 86 of the press contact bar 83 comes into contact with the second surface 106b of the cam portion 106 and the second position for locking the press contact bar 83 to the fixed position It is provided so that it can rotate between them.

  The lock bar 103 is formed of a rod-like member extending in the longitudinal direction in the horizontal frame body 21 whose one end engages with the lock cam 101 or is positioned in the vicinity of the lock cam 101 and the other end contacts the contact portion 102a of the link cam 102. Has been. For example, the lock bar 103 is provided so as to be movable in the longitudinal direction in the horizontal frame body 21 while being placed on the interior body 26. The lock bar 103 is provided in the horizontal frame 21 so as to be movable in the longitudinal direction. The lock bar 103 has one end engaged with the cam surface 105b of the cam portion 105 of the lock cam 101 when the lock cam 101 is positioned at the first lock position and the press contact bar 83 is positioned at the retracted position, and The first surface 106a of the cam portion 106 is in contact with the contact portion 102a of the link cam 102 where the first surface 106a is in contact with the front end surface of the engagement piece 86 of the press contact bar 83, and the lock cam 101 is locked in the first lock position. It is formed with the length to obtain. Further, the lock bar 103 is brought into contact with a contact portion 102a of the link cam 102 in which the second surface 106b of the cam portion 106 is in contact with the lower surface of the engagement piece 86 of the pressure contact bar 83 with the pressure contact bar 83 positioned at a fixed position. When the other end abuts, the second end is allowed to rotate the lock cam 101, and when the lock cam 101 is positioned at the second lock position, the one end surface is perpendicular to the cam portion 105 of the lock cam 101. Engagement in which the second surface 106b of the cam portion 106 of the link cam 102 is in contact with the lower surface of the engagement piece 86 of the pressure contact bar 83 even if the second surface 105c is opposed to the second surface 105c. It is also formed in a length that does not release the state. As a result, the lock bar 103 has one end engaged with the lock cam 101 and the other end abutted against the link cam 102 to lock the lock cam 101 in the first lock position and the other end in the second position. Link cam lock that abuts the link cam 102 and allows one end to allow the rotation of the lock cam 101 and prevents the movement from the other end to the one end when the lock cam 101 is in the second lock position and locks the link cam 102 to the second position. The horizontal frame 21 is provided so as to be movable between positions.

  The lock bar 103 is urged from one end to the other end side. The biasing means for performing the biasing is not particularly limited, and for example, a coiled biasing spring 107 is used. The urging spring 107 is mounted so as to be wound around the outer periphery of the lock bar 103, and has one end in contact with the receiving seat 108 and the other end in contact with the contact seat 109. The receiving seat 108 is formed in a flat plate shape having a through hole 108a through which the lock bar 103 passes, and both sides are fitted into the fitting holes 27c of the pair of reinforcing plates to form the fitting holes 27c. It is in contact. The abutment seat 109 has a through hole 109a through which the lock bar 103 passes and a contact piece 109b with which the engagement hook 104 contacts, and is formed in a flat plate shape that fits into the fitting hole 27c. Abut. Thus, the lock bar 103 is always urged from one end to the other end side by the urging force of the urging spring 107. The receiving seat 108, the biasing spring 107, and the contact seat 109 are attached so as to be positioned above the holding member 9 in the release position. Further, the protrusion 103c of the lock bar 103 is inserted into a guide hole 27d that communicates with the fitting hole 27c and moves the lock bar 103 in the longitudinal direction.

  The urging spring 107 urges the link cam 102 so that the other end of the lock bar 103 abuts against the abutting portion 102 a of the link cam 102 and the cam portion 106 is pressed against the pressing bar 83. Thereby, when the pressure contact bar 83 is positioned at the retracted position and the first surface 106a of the cam portion 106 of the link cam 102 is in contact with the front end surface of the engagement piece 86 of the pressure contact bar 83, one end of the lock bar 103 is locked to the lock cam. 101 is engaged with the cam surface 105b of the cam portion 105, so that the holding member 9 cannot be rotated and the door 3 is locked unless the pressure contact bar 83 is positioned at a fixed position, that is, the base frame 2 is fixed. The state is maintained (see FIG. 13). Further, when the pressure contact bar 83 is moved from the retracted position to the fixed position, that is, when the base frame 2 is fixed, the pressure contact bar 83 moves upward and the cam portion 106 of the link cam 102 contacts the engagement piece 86 of the pressure contact bar 83. Moves from the front end surface to the lower surface, and the portion of the cam portion 106 that contacts the engagement piece 86 also moves from the first surface 106a to the second surface 106b, that is, the urging force of the urging spring 107 causes the lock bar 103 to move. It moves from one end to the other end side and is positioned at the link cam lock position. At this time, the engagement between the one end of the lock bar 103 and the cam surface 105b of the cam portion 105 of the lock cam 101 is released (see FIG. 14). That is, when the base frame 2 is fixed, the door 3 can be unlocked. In this state, when the holding member 9 is rotated from the engagement position to the release position, the lock cam 101 is also rotated with this rotation, and the lock cam 101 is moved from the first lock position to the second lock position. In addition, the figure shown by C of FIG. 14 is a figure which shows the state in the middle of rotation of this holding member 9. FIG. When the lock cam 101 is moved from the first lock position to the second lock position, the second surface 105c of the lock cam 103 is opposed to the second surface 105c of the cam portion 105 of the lock cam 101. Even if the one end surface comes into contact with 105c, the engagement state where the second surface 106b of the cam portion 106 of the link cam 102 is in contact with the lower surface of the engagement piece 86 of the press contact bar 83 is not released, and the press contact bar 83 is locked. It is held (see FIG. 15). That is, when the door 3 can be opened and closed (when the support of the door 3 is not supported by the holding member 9), the base frame 2 is locked in a fixed state and cannot be released. It is like that. By rotating the holding member 9 from the release position to the engagement position from this state, the press contact bar 83 can be moved from the fixed position to the retracted position.

  The engagement hook 104 is provided in the lateral frame body 21 on the link cam 102 side from the contact seat 109 in the vicinity of the contact seat 109. The engagement hook 104 is formed as a contact portion 104b in which the upper end of the base portion 104a extending in the vertical direction bends to a side orthogonal to the contact seat 109 side and the tip can contact the contact piece 109b of the contact seat 109. Further, the lower end of the base portion 104a is formed in a substantially U-shape formed as an engaging portion 104c protruding in a right triangle shape inclined downward toward the contact seat 109 side. The upper side of the center portion of the base portion 104a of the engagement hook 104 is rotatably attached to the horizontal frame body 21 via a rotation shaft 104d. The engagement hook 104 has a length between the contact portion 104b and the engagement portion 104c that is longer than the length in the width direction of the holding member 9 excluding the step portion 96 on the lower end surface of the holding member 9. Become.

  As a result, when the lock bar 103 is positioned at the link cam 102 lock position, the contact piece 109b of the contact seat 109 opposite to the side on which the biasing spring 107 is in contact with the contact portion 104b. In this state, when the holding member 9 is rotated from the engagement position to the release position, the lower corner portion of the holding member 9 where the step portion 96 is not provided is in contact with the engagement portion 104c during the rotation. The hook 104 is rotated about the rotating shaft 104d against the urging force of the contact portion 104b and rotated counterclockwise in the illustrated example, and the lower end of the holding member 9 excluding the step portion 96 is from the engaging portion 104c. When the holding member 9 reaches the release position by reaching the upper side, the engaging hook 104 rotates in the reverse direction by the urging force of the urging spring 107, and the engaging portion 104 c engages with the surface of the holding member 9 forming the step 96. The holding member 9 is in the release position Tsu is adapted to be click. Further, when a force larger than the urging force of the urging spring 107 is applied in the direction in which the holding member 9 is released from the release position from the state where the holding member 9 is locked at the release position, the holding member 9 rotates and engages. The hook 104 also rotates to release the engagement by the engagement hook 104 so that the holding member 9 reaches the engagement position. That is, the engagement hook 104 is rotatably provided between a lock position that locks the holding member 9 in the release position and a release position that releases the engagement of the holding member 9.

  Now, the moving wall 1 with a door is connected with the connecting portion 11a of the suspension device 11 at the upper end near both sides in the width direction, like the moving wall 15, that is, the moving wall 15 without the door 3. It can be moved to a predetermined location along the rail 12 together with the two suspension vehicle devices 11. Therefore, when dividing by the plurality of moving walls 15, the door-attached moving wall 1 is moved to a predetermined position. After the movement, the operating jig is inserted into the operating hole 284, and the operating hole 284 is inserted into the vertical frame. The pressure bar 83 extends from the vertical frame 22 and engages with the rail 12, and the moving bar 82 extends downward from the vertical frame 22 and engages with the floor 19 to fix the base frame 2. To do. Thereby, the movable wall 1 with a door is installed in a state where it is fixed at a predetermined position (see FIG. 1), and the door 3 can be opened and closed when the door 3 is opened and closed. Since the door 3 is rotatably attached to the horizontal frame body 21 and the receiving portion 23 of the base frame 2 via the first rotating shaft 4 and the second rotating shaft 5, when the door 3 is opened, the door 3 is also on the near side. The door 3 can also be rotated in both directions on the back side. Further, by providing the door closer 20 between the upper frame 31 of the door 3 and the horizontal frame body 21, the door 3 is automatically closed after being opened.

  The first rotating shaft 4 for rotatably attaching the door 3 to the base frame 2 is attached to the upper end of the door 3, and the upper portion of the first rotating shaft 4 is supported in a suspended manner in the horizontal frame body 21. ing. The 2nd rotating shaft 5 is attached to the receiving part 23, and is supported by the door 3 so that rotation is possible. In this way, the door 3 is attached to the base frame 2 so as to be rotatable via the first rotating shaft 4 and the second rotating shaft 5 while being supported by being suspended from the first rotating shaft 4. The horizontal frame 21 of the base frame 2 is provided with a holding member 9 that supports the door 3 so that the door 3 is releasably suspended and held in a closed state. The holding member 9 is interlocked with the fixing mechanism 8 by the interlocking mechanism 10. For this reason, the safety of the movable wall 1 with a door becomes high.

  That is, when the moving wall 1 with the door is moved, the base frame 2 is unfixed, and this state is when the door 3 is suspended and supported by the holding member 9 and held in the closed state. At this time, the door 3 is locked in the closed state. Specifically, when the moving wall 1 with the door is moved, the holding member 9 is engaged with the support pin 90 so that the door 3 is suspended and supported by the holding member 9 so that the door 3 is not opened and closed. The door 3 is locked and the fixing of the base frame 2 by the fixing mechanism 8 is released, that is, the press contact bar 83 and the moving bar 82 are positioned at the retracted position. Only in this state, the movable wall with door 1 can be moved. At this time, since the pressure contact bar 83 is positioned at the retracted position and the first surface 106a of the cam portion 106 of the link cam 102 is in contact with the front end surface of the engagement piece 86 of the pressure contact bar 83, one end of the lock bar 103 is locked to the lock cam 103. The cam surface 105b of the cam portion 105 of 101 is engaged. For this reason, unless the pressure contact bar 83 is positioned at a fixed position, that is, the base frame 2 is not fixed, the holding member 9 cannot be rotated and the door 3 cannot be opened or closed while the door 3 is locked (FIG. 13). reference.). Therefore, the movable wall 1 with a door can be safely moved without the door 3 being opened. At this time, the pressing bar 83 is held at the retracted position by the biasing force of the biasing spring 387. Therefore, the pressing bar 83 does not move while moving the moving wall 1 with the door. The wall 1 can be moved. Moreover, when storing the moving wall 1 with a door, the moving wall 1 with a door can be safely stored without opening the door 3 by storing in the same state as when moving.

  Further, after the door-mounted moving wall 1 is moved to a predetermined position, the operation jig is inserted into the operation hole 284 and the operation hole 284 is rotated with respect to the vertical frame 22 to press the bar. 83 is extended from the vertical frame body 22 and engaged with the rail 12, and the moving bar 82 is extended downward from the vertical frame body 22 and engaged with the floor 19 to fix the base frame 2. Thereby, the movable wall 1 with a door is installed in the state fixed to the predetermined position. At this time, the pressure contact bar 83 is held at the fixed position by the urging force of the urging spring 387, so that the movable wall with door 1 is securely fixed at that position.

  As described above, when the pressure contact bar 83 is moved from the retracted position to the fixed position, that is, when the base frame 2 is fixed, the pressure contact bar 83 moves upward, and the cam portion 106 of the link cam 102 is moved along with this movement. The portion in contact with the engagement piece 86 moves from the front end surface to the lower surface, and the portion in contact with the engagement piece 86 of the cam portion 106 also moves from the first surface 106a to the second surface 106b. That is, the lock bar 103 is moved from one end to the other end side by the urging force of the urging spring 107 and is positioned at the link cam lock position, and is engaged with the cam surface 105b of the cam portion 105 of the lock cam 101 at one end of the lock bar 103. Is released (see FIG. 14).

  As a result, the holding member 9 can be rotated from the engagement position to the release position, that is, the door 3 can be unlocked. The operating member is engaged with the engaging portion 92a of the operating lever 92, and the operating lever 92 is rotated about the rotating member 91 so that the holding member 9 is in the release position. Then, the holding member 9 is rotated from the engagement position to the release position by the rotation member 91. With this rotation, the lock cam 101 also rotates and the lock cam 101 moves from the first lock position to the second lock position. At this time, since one end surface of the lock bar 103 is opposed to the second surface 105c of the cam portion 105 of the lock cam 101, the cam of the link cam 102 even if the one end surface abuts on the second surface 105c. The engagement state in which the second surface 106b of the portion 106 is in contact with the lower surface of the engagement piece 86 of the press contact bar 83 is not released, and the press contact bar 83 is held in a locked state (see FIG. 15). That is, the fixing of the base frame 2 is locked. Therefore, since the door 3 cannot be opened or closed unless the base frame 2 is fixed, the door 3 is not unlocked during the operation of fixing the base frame 2 and the door 3 does not open. The wall 1 can be installed. Moreover, although the operation | movement which fixes the base frame 2 was performed, when the base frame 2 cannot be fixed, the door 3 does not open. Furthermore, since the base frame 2 is always fixed when the door 3 is opened and closed, the door 3 can be opened and closed safely without the base frame 2 moving. When the holding member 9 is positioned at the release position, the holding member 9 is locked at the release position via the engagement hook 104 by the biasing force of the biasing spring 107, so that the door 3 can be opened and closed more safely. .

  In addition, when the door 3 can be opened and closed, that is, when the support of the door 3 is not supported by the holding member 9, the base frame 2 is locked in a fixed state, and the base frame 2 cannot be fixed. For this reason, when the door 3 is opened and closed, the fixing of the base frame 2 is not accidentally released, so that the door 3 can be opened and closed more safely.

  For example, when the door 3 is not opened or closed at night or the like while the movable wall 1 with the door is installed at a predetermined position, the operating member is engaged with the engaging portion 92a of the operating lever 92. 92 is rotated around the rotating member 91 so that the holding member 9 is in the engaged position. Then, the holding member 9 is rotated from the release position to the engagement position by the rotation member 91, the holding member 9 is engaged with the support pin 90 of the door 3, and the door 3 is supported by being suspended. Thereby, it is possible to prevent the door 3 from being opened and closed while the base frame 2 is fixed.

  Further, in order to move the moving wall 1 with the door installed at a predetermined position to another position, the holding member 9 is rotated from the release position to the engaging position to be engaged with the support pin 90 and the door 3 is also suspended by the holding member 9. Lower and support. When the holding member 9 rotates in this way, the lock cam 101 rotates by its own weight from the second lock position to the first lock position, and the second surface 105 c of the cam portion 105 of the lock cam 101 is close to one end surface of the lock bar 103. The canceled state is released. This state is the state shown in FIG. In this state, the operation jig is inserted into the operation hole 284 while being inserted, and the operation hole 284 is rotated with respect to the vertical frame body 22 so that the pressure contact bar 83 is retracted to the vertical frame body 22 and And the moving bar 82 is retracted to the vertical frame body 22 to release the engagement with the floor 19 and the fixing of the base frame 2 is released. Thus, since the fixing of the base frame 2 is locked in the state where the engagement of the door 3 by the holding member 9 is released, the base frame 2 is fixed unless the door is held in the closed state by the holding member 9. Since it cannot be released, the door does not open during the operation of releasing the fixing of the base frame 2. Therefore, the base frame 2 can be safely released.

  Therefore, the movable wall 1 with a door of this embodiment is excellent in safety.

  Further, when the moving wall 1 with the door is moved or stored, the door 3 is suspended and supported by the horizontal frame 21, that is, the base frame 2, by the two members of the first rotating shaft 4 and the holding member 9. Is distributed to the first rotating shaft 4 and the support pin 90, the total load of the door 3 does not act only on the first rotating shaft 4. Further, since the position of the support pin 90 with respect to the door 3 can be moved or adjusted in the vertical direction, the load applied to the first rotating shaft 4 can also be adjusted.

  Further, when the base frame 2 is fixed and the door 3 is opened and closed, the suspension support of the door 3 by the holding member 9 is released. It can be performed only after the base frame 2 is fixed by extending from the body 22 and engaging with the rail 12 and extending the moving bar 82 downward from the vertical frame body 22 and engaging with the floor 19. For this reason, when the door 3 is opened and closed, the second rotary shaft 5 is attached to the receiving portion 23 protruding from the vicinity of the vertical frame body 22 engaged with the floor 19. A part of the load is supported, and the total load of the door 3 does not act only on the first rotating shaft 4.

  As described above, in the movable wall 1 with a door according to the present embodiment, the entire load of the door 3 does not act only on the first rotating shaft 4. The door 3 can be supported sufficiently.

  The interlock mechanism 10 is provided on the horizontal frame 21 so as to be rotatable between a first lock position that locks the holding member 9 in the engagement position and a second lock position that locks the press contact bar 83 in the fixed position. Provided in the horizontal frame 21 so as to be rotatable between the lock cam 101 and the first position allowing the pressure bar 83 to move from the retracted position to the fixed position and the second position locking the pressure bar 83 to the fixed position. The link frame 102 is provided on the horizontal frame 21 so as to be movable between a link cam 102, a lock cam lock position that locks the lock cam 101 in the first lock position, and a link cam lock position that locks the link cam 102 in the second position. By adopting a configuration having the lock bar 103 and the engagement hook 104 that locks the holding member 9 in the release position, the safety of the movable wall 1 with a door is reliably ensured with a simple structure. Door can be.

  In addition, when the press contact bar 83 is extended from the vertical frame body 22 and engaged with the rail 12 to fix the upper portion of the base frame 2, the press contact plate urged upward by the press contact spring 180 at the tip of the press contact bar 83. 84, and the two positioning pins 85 provided on the pressure contact plate 84 are inserted into the engaging holes 14a of the pin receiving plates 14 attached to the lower surfaces of the pair of lower sides of the rail 12, respectively, so that positioning is performed. Can be reliably positioned at a predetermined position. At this time, the reduced diameter portion 85a is provided above the positioning pin 85, and the engagement hole 14a of the pin receiving plate 14 is gradually expanded from the opening on the rail 12 side toward the opening on the pressure contact plate 84 side. As a result, the positioning pin 85 can be reliably inserted into the engagement hole 14a. Then, after the positioning pin 85 is inserted into the engagement hole 14a of the pin receiving plate 14, the press contact plate 84 comes into surface contact with the pin receiving plate 14 and the upper portion of the base frame 2 is fixed. At this time, the press contact plate 84 is biased upward by the press contact spring 180, so even if an error occurs in the height to the location where the rail 12 is provided, the error is caused by the bias force of the press contact spring 180. The upper part of the base frame 2 can be securely fixed.

  Further, since the holding mechanism including the direction changing bar 382 and the urging spring 387 as the urging means is provided on the fixing mechanism 8, the pressing bar 83 and the moving bar 82 at the retracted position can be respectively held at the retracted position. In addition, the pressing bar 83 at the fixed position and the moving bar 82 at the engaged position can be held at the fixed position and the engaged position, respectively. Further, when the pressure changing bar 382 or the moving bar 82 moves from the retracted position to the fixed position and the engaged position, the tip of the second side 382b moves downward in an arc shape in the direction changing bar 382 formed in a bent shape. By forming the direction change bar 382 so as to stop at a position slightly beyond the lowest position in the vertical direction of the rotation axis, the pressure contact bar 83 and the moving bar 82 are completely in the fixed position and the engagement position. If the frame 2 is not fixed, the direction changing bar 382 is rotated by the urging force of the urging spring 387, and the pressing bar 83 and the moving bar 82 are moved to the retracted position. That is, when the base frame 2 is not completely fixed, the press contact bar 83 and the moving bar 82 return to the retracted position, so that the fixed state of the base frame 2 can be easily grasped.

  In addition, a first axis adjusting unit 6 that adjusts the position of the first rotating shaft 4 in the width direction of the door 3 and a second axis adjusting unit 7 that adjusts the position of the second rotating shaft 5 in the width direction of the door 3. , The positions of the first rotating shaft 4 and the second rotating shaft 5 can be adjusted, respectively, and the door 3 can be adjusted to rotate smoothly with respect to the base frame 2.

The first adjustment screw 63 is moved in the second width direction opposite to the first width direction, and the first adjustment screw 63 is moved toward the first slide member 61 in a direction approaching the screwing position of the first slide member 61. Since the upper part of the door 3 is moved in the first width direction with respect to the first rotating shaft 4 by rotating the door 3 by its own weight, the position of the first rotating shaft 4 can be reliably adjusted with a simple structure. .

  The second shaft adjustment portion 7 is slid on the lower frame 32 so as to be slidable in the width direction of the door 3, the second fixing member 72 fixed on the door 3, and the second slide member 71 is slid As a configuration including the second adjusting screw 73 to be rotated, the second adjusting screw 73 is rotated with respect to the second fixing member 72 in a direction in which the tip is separated from the screwing position with the second fixing member 72. The lower part moves in the second width direction with respect to the second rotating shaft 5, and the second adjusting screw 73 is moved relative to the second fixing member 72 in the direction in which the tip approaches the screwing position of the second fixing member 72. Since the lower part of the door 3 is moved in the first width direction with respect to the second rotation shaft 5 by its own weight, the position of the second rotation shaft 5 can be reliably adjusted with a simple structure.

  The first rotating shaft 4 is between two fixing points of the horizontal frame body 21 to which the suspension vehicle attachment member 18 to which the connecting portion 11a of the suspension device 11 is attached is in the vicinity of the fixing point on the vertical frame body 22 side.
