Description

TECHNICAL FIELD The present invention relates to a movable partition device, and more particularly to a movable partition device having a partition panel with a door.

A room such as an office, a conference room, a showroom, a store, etc. is suspended and supported by rails provided on the ceiling, and partition panels movable along the rails are connected to divide the rooms into desired small compartments. Layout is implemented. In such a moving partition device, there is known one in which a partition panel with a door is used at a predetermined position to enable movement between two partitioned spaces (see Patent Document 1). ).

A partition panel with a door disclosed in Patent Document 1 includes an inverted L-shaped frame and a door attached to the frame by hinges. A rod is vertically guided and mounted so as to be movable up and down. A sealing member arranged at the bottom of the frame moves up and down toward the floor according to the vertical movement of the operating rod. When fixing the frame to the floor, the operating rod is lowered to seal The members are fixed by pressing them against the floor surface.

Further, a substantially triangular link is pivotally attached to the operating rod, one end of the link is pivotally supported and attached to the frame, and the other end of the link is a horizontally extending connecting rod. A bar is pivotally attached. The link moves the connecting rod horizontally by rotating around a shaft supported by the frame as the operating rod moves up and down. That is, the link attached to the operating rod converts the vertical motion of the operating rod into horizontal motion. Therefore, when the operation rod is lowered, the sealing member of the frame is lowered to be pressed against the floor surface, and the connecting rod is protruded in the direction of the door body to press the pressing part horizontally protruding from the door body. A sealing member arranged on the lower part of the body is lowered.

The frame includes a conversion member between the pressing portion and the operation rod,
The converting member is characterized by comprising a slidable contact surface that is in slidable contact with the operating rod and a contact surface that can contact the pressing portion.
According to this feature, when the operating rod moves up and down, the operating rod comes into sliding contact with the inclined sliding contact surface, the conversion member is moved in the horizontal direction, and the contact surface is brought into contact with the pressing portion. Since the conversion members can move in a state in which they are not restrained, and the load is not likely to concentrate on a part of the conversion members even if they are used repeatedly, by lowering the operation rod, the frame is fixed to the floor and the door is fixed. It is possible to provide a highly durable movable partition panel with a door while lowering the sealing member.

One end of the converting member is rotatably supported by the frame, and the other end of the converting member is arranged to face the pressing portion.
According to this feature, the amount of vertical movement of the operating rod can be used to amplify the lateral movement width of the other end.

A sliding contact surface of the converting member is set at an angle of 45 degrees or less with respect to the operating direction of the operating rod.
According to this feature, the efficiency of converting the vertical movement of the operating rod to the horizontal direction is good, and the operability is good.

The inclined state of the sliding contact surface is gradually changed from a predetermined angle of 45 degrees or less to 0 degree with respect to the operating direction of the operating rod.
According to this feature, once the sliding contact surface of the converting member is slidably contacted by the operating rod and becomes 0 degrees, the angle of the converting member does not change even if it is slidably contacted by the operating rod thereafter. Excessive intrusion into the door side can be prevented.

The lower end of the operating rod is characterized in that it is a French drop that is inserted through a hole provided on the floor surface.
According to this feature, the frame and the floor can be firmly fixed by lowering the operating rod.

The inclined surface of the operating rod is inclined at 45 degrees or less with respect to the operating direction of the operating rod.
According to this feature, the conversion member can be brought into contact with the conversion member smoothly, and the conversion member can be swung left and right.

When the projection 87a of the rotary drive portion 87B is adjusted to the 0 o'clock position by a crank handle (not shown), the middle plate 85 rises and the bar member 83 rises together, so that the dropping rod 86a is disengaged from the receiving member 86b. be done. At the same time, the left end portions of the pair of swinging members 81, 81 are raised and the right end portions are lowered, so that the plate member 82 is lowered and engaged with the engagement groove 73a (see FIG. 3).

FIG. 7(b) shows a state in which the movable partition panel 1 with a door is erected on the floor surface F. As shown in FIG. At this time, the movable partition panel 1 with a door is fixed to the floor surface F while being moved until it comes into contact with the wall W (see FIG. 1). When the projection 87a of the rotation drive portion 87B is turned to the 6 o'clock position by a crank handle (not shown), the middle plate 85 is lowered and the bar member 83 is lowered together, so that the drop rod 86a is inserted into and engaged with the receiver 86b. . At the same time, the left end portions of the pair of swinging members 81, 81 are lowered and the right end portions are raised, so that the plate member 82 is raised and disengaged from the engagement groove 73a (see FIG. 3).

Referring to FIG. 8, the sliding rod 88 has a pair of horizontally projecting protrusions 88d, 88d integrally formed at the lower end of the right side surface of a hard material formed into a prism shape. formed in the shape of Through holes 88a, 88a are formed through the sliding rod 88 from a vertical surface 88b on the right side to a vertical surface on the left side. It is installed parallel to the longitudinal direction and on the door body 7 side. (See Fig. 9)

Below the vertical surface 88b side of the sliding rod 88, a slit portion 88e is formed which is recessed inwardly, ie, leftwardly. The slit portion 88e is partitioned by an inwardly recessed inclined surface 88c and inner flat surfaces 88f, 88f of the protrusion 88d, and the length from the inner flat surface 88f on one side to the inner flat surface 88f on the other side is a is slightly wider than the length b from an inner flat surface 89d on one side of the conversion member 89 to be described later to an inner flat surface 89d on the other side. (a>b) Therefore, the conversion member 89 can be inserted into the slit portion 88e. In addition, inner flat surfaces 88f, 88f that define the slit portion 88e restrict movement of the conversion member 89 in the front-rear direction.

The converting member 89 is made of hard material formed into a prism shape, and a rubber cap 89c is attached to the lower end of the right side thereof. ing. A shaft 92 is inserted through the through hole 89a, and both ends of the shaft 92 are attached and fixed to the front and rear plate portions of the vertical square tube 25b, so that the conversion member 89 swings in the vertical square tube 25b toward the door 7. movably arranged. A flat sliding surface 89b on the opposite side to which the rubber cap 89c of the converting member 89 is attached can contact the flat inclined surface 88c and the vertical surface 88b of the sliding rod 88. As shown in FIG.

9(a) and 9(b), the rotation driving portion 87B (see FIG. 7) is operated to lower the lower rod 86 and the drop rod 86a so that the lower closing member 13 of the frame 2 and the door 7 are separated from each other. A mode of lowering the lower closing member 12 to the floor surface F and inserting the drop rod 86a into the receiver 86b will be described.

As shown in FIG. 9(a), when the lower rod 86 and the drop rod 86a are raised, a slit (see FIG. 6) is formed below the vertical square tube 25b on the side of the lower rod 86. Therefore, the sliding rod 88 is driven by the downward movement of the lower rod 86 in the vertical tube 25b with the headed screws 88g, 88g connected to the lower rod 86. As shown in FIG.

A lower frame 75 of the door 7 includes a lower closing member 12, a leaf spring 76a as a lower advancing/retreating mechanism for advancing and retreating the lower closing member 12, and a leaf spring 76a connected to pivotally support the lower closing member 12. A pivoting mechanism 76d, an urging mechanism 76b connected to the end of a plate spring 76a on the frame 2 side, and an urging mechanism 76 can be horizontally moved into and out of the urging mechanism 76 on the frame 2 side. A rod-shaped pressing portion 76c to be connected is provided. As shown in FIG. 9A, when the lower rod 86 and the drop rod 86a are raised, the leaf spring 76a is in a natural state extending to the left and right, and the pressing mechanism connected to the biasing mechanism 76b is in a natural state. The portion 76c presses the rubber cap 89c of the conversion member 89 by receiving the biasing force toward the frame 2, and tilts the conversion member 89 at a predetermined angle θ1 of 40 degrees with respect to the operating direction of the lower rod 86 and drop rod 86a. It is designed to let

As shown in FIG. 9(b), in the state where the lower rod 86 and the drop rod 86a are lowered, the lower rod 86 and the drop rod 86a are externally fixed to the lower rod 86 as they are lowered. The ring member 91 moves the adjuster 90 with a spring (not shown) downward, and the lower end of the adjuster 90 is attached to the lower end of the frame 2. The member 13 is brought into pressure contact with the floor surface F. The tip of the lowered drop rod 86a is inserted into a receiver 86b that forms a French drop together with the drop rod 86a arranged in a hole drilled in the floor surface F.

Further, as the lower rod 86 and the drop rod 86a are lowered, the slide rod 88 connected to the lower rod 86 is also lowered. The conversion member 89 tilted at the predetermined angle θ1 swings when it comes into sliding contact with the vertical surface 88b of the sliding rod 88, and the tilt angle approaches 0 degree. The swinging conversion member 89 presses the pressing portion 76c on the side of the door 7 to the right because the rubber cap 89c is moved in the horizontal direction. The pressed pressing portion 76c presses the end of the plate spring 76a in the biasing mechanism 76b, and the plate spring 76a receives the biasing force and bends downward. When the plate spring 76a is bent downward, the pivot mechanism 76d attached to the substantially central portion of the plate spring 76a and the lower closing member 12 pivotally supported by the pivot mechanism 76d are directed toward the floor surface F. It is designed to be lowered.

The operation of the sliding rod 88 and the conversion member 89 will be described in detail with reference to FIGS. 10(a) to 10(d). When the lower rod 86 and the drop rod 86a are raised as shown in FIG. 10(a), the boundary line 88h (see FIG. 8) between the vertical surface 88b and the inclined surface 88c of the sliding rod 88 is the conversion member. The conversion member 89 is positioned C1 above the center of rotation of the conversion member 89, and is inclined at a predetermined angle θ1 by being pressed by the pressing portion 76c.

As described above, the boundary line 88h (see FIG. 8) is located above the rotation center of the conversion member 89 by C1, so that the sliding contact surface 89b of the conversion member 89 is reliably brought into surface contact with the inclined surface 88c. The position of the conversion member 89 can be regulated by moving it.

When the lower rod 86 and the drop rod 86a are lowered from the state shown in FIG. After that, the sliding contact surface 89b of the converting member 89 separates from the inclined surface 88c of the sliding rod 88, and the lower end of the vertical surface 88b of the sliding rod 88 and the upper side of the sliding contact surface 89b of the converting member 89 slide. The member 89 is swung toward the door 7, and the boundary line 88h of the sliding rod 88 shown in FIG. At this time, the pressing portion 76c is pressed rightward by the rubber cap 89c being moved rightward.

When the lower rod 86 and the drop rod 86a are further lowered from the state of FIG. 10(b), and the boundary line 88h of the sliding rod 88 is positioned C3 below the rotation center of the conversion member 89 (C3>C2). 10(c), the vertical surface 88b of the sliding rod 88 and the sliding contact surface 89b of the converting member 89 become parallel, and the converting member 89 is in a vertical state. The rubber cap 89c included in the conversion member 89 presses the pressing portion 76c to lower the lower closing member 12 of the door 7, thereby completing closing of the lower portion of the door 7. As shown in FIG.

When the lower rod 86 and the drop rod 86a are further lowered from the state of FIG. 10(c), the boundary line 88h of the sliding rod 88 is positioned further than the rotation center of the conversion member 89 as shown in FIG. 10(d). Positioned downward by C4 (C4>C3), the drop rod 86a is in a state in which it penetrates by a predetermined amount or more into the receiving member 86b arranged in the hole drilled in the floor surface F, and is securely engaged with the receiving member 86b. As they are brought together, the lower closing member 13 of the frame 2 abuts against the floor surface F with a predetermined pressing force. In this way, the blockage of the lower part of the frame 2 and the French drop are completed.

In FIG. 10(c), the vertical surface 88b of the sliding rod 88 slides against the sliding surface 89b of the converting member 89, so that the converting member 89, which is in a vertical state, is thereafter moved to the lower rod 86 and the dropper. Even if the rod 86a is lowered, since the vertical surface 88b of the sliding rod 88 is formed vertically, it is only slidably contacted by the sliding contact surface 89b and does not tilt or swing. From FIG. 10(c) to FIG. 10(d), the lower closing member 12 of the door 7 maintains its position. In this way, the sliding rod 88 and the converting member 89 are independently operable, and the swinging of the converting member 89 that is not proportional to the drop margins of the lower rod 86 and the drop rod 86a is possible. The rubber cap 89c provided on the member 89 can be prevented from excessively entering the door body 7 side.

Next, opening and closing of the door 7 will be described with reference to FIG. In FIG. 11, for convenience of explanation, the gear hinge 5 is indicated by a double-dotted dashed line, and the vertical rectangular tube 25b on the side of the door 7 is cut away.

As shown in FIG. 11(a), when the door 7 and the gear hinge 5 connected to the door 7 are closed, the pressing portion receives a leftward biasing force from the biasing mechanism 76b (see FIG. 9). 76c is in pressure contact with the rubber cap 89c provided in the conversion member 89 on the frame 2 side, so that the lower closing member 12 of the door 7 is in contact with the floor surface F, preventing sound and light. It is designed to prevent leakage. (Same state as in FIG. 10(d))

As shown in FIG. 11(a), when the door 7 and the gear hinge 5 connected to the door 7 are opened, the opening margin of the door 7 is opened counterclockwise around the gear hinge 5. Accordingly, the pressing portion 76c that receives the leftward biasing force from the biasing mechanism 76b gradually protrudes leftward. As the pressing portion 76c protrudes leftward, the plate spring 76a (see FIG. 9) connected to the biasing mechanism 76b tries to return to its natural state from the bent state, and the pivot attached to the plate spring 76a is released. The support mechanism 76d and the lower closure member 12 attached to the pivot mechanism 76d are moved upward. When the door 7 is opened so that the pressing portion 76c can protrude by a predetermined width, the lower closing member 12 of the door 7 is accommodated in the lower frame 75 (see FIG. 9).

As described above, the frame 2 includes the conversion member 89 between the pressing portion 76c and the sliding rod 88. The converting member 89 has a sliding contact surface 89b that is slidably contacted with the sliding rod 88 in an inclined state, Since the rubber cap 89c that can contact the pressing portion 76c is provided, the vertical movement of the sliding rod 88 causes the sliding rod 88 to slide on the inclined sliding contact surface 89b, and the conversion member 89 moves horizontally. Since the rubber cap 89c is brought into contact with the pressing portion 76c, the sliding rod 88 and the conversion member 89 can move in a state in which they are not restrained, and the load is concentrated on a part of the conversion member 89 even after repeated use. Therefore, by lowering the sliding rod 88, the fixing of the frame 2 to the floor surface F and the lowering of the lower closing member 12 of the door 7 are performed in conjunction with each other. A moving partition panel 1 with body can be provided.

In addition, since the sliding rod 88 and the conversion member 89 can move without being constrained, it becomes easy to adjust the pressing force of the lower closing member 12 of the door 7 and the lower closing member 13 of the frame 2 individually. there is

A series of operations for raising and lowering the lower rod 86 interlocks the closed state of the lower closing member 12 of the door 7 and the insertion/removal state of the drop rod 86a, so that workability is excellent. Furthermore, the insertion and removal of the lower closing member 13 of the frame body 2 are linked by a series of operations for raising and lowering the lower rod 86, so that workability is extremely excellent.

A through hole 89a of the conversion member 89 is pivotally supported by the frame 2 by a shaft 92, and a rubber cap 89c included in the conversion member 89 is disposed so as to face the pressing portion 76c. Therefore, the amount of vertical movement of the sliding rod 88 can be used to amplify the lateral movement width of the other end.

The conversion member 89 swings when the boundary line 88h (see FIG. 8) of the sliding rod 88 is positioned below the rotation center of the conversion member 89 (between FIGS. 10A and 10B). The distance C3 between the boundary line 88h (see FIG. 8) at the position (FIG. 10(c)) where the swinging is completed and the center of rotation of the converting member 89 is Since it is sufficiently smaller (C3<L) than the distance L (see FIG. 8) from the center to the rubber cap 89c, the lateral movement width of the other end side of the conversion member 89 can be amplified by the so-called lever principle. there is Considering the reliability of operation, L should be three times or more, preferably ten times or more, the length of C3.

Since the sliding contact surface 89b of the converting member 89 is set at an angle of 45 degrees or less with respect to the operation direction of the sliding rod 88, the vertical movement of the sliding rod 88 can be efficiently converted to the horizontal direction, and the operation is improved. Good nature. From the viewpoint of reliable operability, the angle is preferably 20 degrees or less.

Since the inclination of the sliding contact surface 89b is gradually changed from a predetermined angle of 45 degrees or less to 0 degree with respect to the operating direction of the sliding rod 88, the sliding of the conversion member 89 is When the contact surface 89b is slidably contacted by the sliding rod 88 and becomes 0 degrees, the angle of the conversion member 89 does not change even if it is slidably contacted by the sliding rod 88 thereafter. Excessive intrusion to the side can be prevented.

Since the sliding rod 88 is provided with the inclined surface 88c, when the lower rod 86 is raised, the sliding contact surface 89b of the conversion member 89 comes into surface contact, and the movement of the conversion member 89 can be stably restricted. can.

Since the lower end of the drop bar 86a is a French drop inserted through a hole provided in the floor surface F, the frame 2 and the floor surface F can be firmly fixed by lowering the drop bar 86a.

Since the inclined surface 88c of the operating rod 88 is inclined at an angle of 45 degrees or less with respect to the operating direction of the operating rod 88, the converting member 89 can be brought into contact with the converting member 89 smoothly, and the converting member 89 can be swung from side to side. can be made

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any changes or additions within the scope of the present invention are included in the present invention. be

For example, a structure in which the sliding rod 88 is not provided and the lower end or the side end of the lower rod 86 directly swings the conversion member 89 may be employed. If the slide rod 88 is provided separately, the lower rod 86 does not need to have a special shape.

Further, although the conversion member 89 has been described as having a plate shape, it may have a sliding contact surface that is in slidable contact with the sliding rod 88, and may be fan-shaped or triangular in plan view, for example.

Further, although the conversion member 89 is pivotally supported by the shaft 92 and provided to be swingable, it is not essential that the conversion member 89 is provided to be swingable. may

Moreover, although the conversion member 89 has been described as an example in which most of it is accommodated within the vertical square tube 25b, it may be attached outside the vertical square tube 25b.
