Description

  The present invention relates to a brake device that prevents a wall surface from being hit with a large impact when the moving wall is pulled out of a storage unit and arranged, and a suspension vehicle for the moving wall.

  The partition has a structure in which a panel is installed and fixed at a predetermined position, and a moving wall that can move the place. The moving wall is constructed so that it can be suspended from the ceiling rail and can be moved to partition a large space in the building as needed. I can do it. When partitioning a large space, it is suspended along a ceiling rail and arranged in a straight line, and when stored, a plurality of moving walls are arranged in parallel at a predetermined interval.

  There are various types of moving walls, from large heavyweights to small lightweight ones, and there are various types of suspension vehicles that suspend and move the moving walls on the ceiling rails. By the way, these moving walls are stored in a storage section provided at one corner of the room, and are pulled out one by one from the storage section and arranged at predetermined positions. At this time, the side edges of the moving walls are gently pressed. However, it may be pressed with great force. As a result, the wall surface is hit with a large impact, the wall surface is scratched, and the suspension car and the suspension bolt may be damaged.

  In view of this, there is also known a technique in which the moving wall that is pulled out of the storage unit and moves does not hit the wall surface of the room with a large impact. For example, the “moving wall brake device” according to Japanese Patent Laid-Open No. Hei 8-232534, when moving the moving wall, even if it is pressed strongly, it travels away from the hand and exerts a large impact force on the wall surface. This is a moving wall brake device that does not collide with it. Therefore, a friction member is attached to the upper end of the moving wall so as to be movable up and down, and the friction member is urged by a spring force to always push upward, and the friction member is an operation unit provided at the side end of the moving wall. At the same time, it works to press the ceiling rail with spring force.

  In addition, the “traveling control device for moving wall” according to Japanese Patent Laid-Open No. 2003-13662 is a travel that prevents the moving speed from increasing when a large moving wall suspended from a ceiling rail is moved in and out of the storage location. It is a control device. Therefore, a damper having a piston lot that expands and contracts is attached on the ceiling rail, and a slider is pivotally supported via a support member at the tip of the piston lot and the slider swings within a certain range. It is possible to control the running speed by contracting the piston lot with the suspension wheel hitting the tip of the slider.

Incidentally, the “moving wall brake device” according to the above-mentioned Japanese Patent Application Laid-Open No. 8-232534 and the “moving wall travel control device” according to Japanese Patent Application Laid-Open No. 2003-13662 have a complicated structure, and therefore the manufacturing cost is It will be high. Of course, when the structure is complicated, the brake operation and the travel control operation are often not stable.
"Moving wall brake device" according to Japanese Patent Application Laid-Open No. 8-232534 “Movement control device for moving wall” according to Japanese Patent Laid-Open No. 2003-13662

  As described above, the brake device provided in the conventional moving wall has the above-described problems. The problems to be solved by the present invention are these problems, so that the brake is automatically applied when the moving wall moving along the ceiling rail approaches the wall surface, so that it does not collide with the wall surface with a large impact. A moving wall brake device and a moving wall suspension vehicle are provided.

  The basic structure of the moving wall is the same as the conventional structure, and is suspended from a ceiling rail attached to the ceiling via a suspension car. The suspension car is attached to both sides of the upper end of the moving wall, and the moving wall is connected to the lower end of the suspension bolt hanging from the suspension car. Here, even if the model of the suspension vehicle is a horizontal wheel model in which two horizontal wheels are rotatably supported with a predetermined interval between suspension bolts, the wheel is rotatably supported on the side surface of the rectangular parallelepiped block body. It may be a vertical wheel type.

  A plate is attached to the inner side surface of the guide portion of the ceiling rail, a resin roller such as urethane is fitted to the suspension bolt, and a hard bush such as metal is fitted to the hole through which the bolt passes. The plate has a certain length and is structured so as to sandwich the roller fitted to the suspension bolt along the guide portion. Here, at least one of the plate and the roller has a friction surface, and when the moving wall moves, it can be slightly compressed to generate a frictional force. The plate is provided in front of the wall surface and functions to act on the moving wall approaching the wall surface.

  Here, the material of the plate is not particularly limited, but urethane rubber is generally used. Urethane rubber has excellent wear resistance and generates a stable frictional force. And the surface which mutually contacts should just be a friction surface to the last, and it can also be set as the structure which bonded friction materials, such as urethane rubber, to the metal plate or the hard resin plate. In the case of the plate, it may be attached to the guide via a spring in order to maintain an appropriate contact pressure with the roller.

  In the moving wall brake device according to the present invention, a plate is attached to the inner side surface of the guide portion of the ceiling rail, and when the moving wall moves and approaches the wall surface, the roller fitted to the suspension bolt is sandwiched between the plates. Sliding friction occurs between them and the brake acts on the moving wall. The length of the plate and the outer diameter of the roller must be appropriate. However, since the structure is very simple, the manufacturing cost is low, the operation is always stable, and there is no fear of failure.

  The roller fitted on the suspension bolt and supported by the shaft is generally made of a relatively soft material having a high coefficient of friction such as urethane rubber. A metal bush or a hard bush corresponding to metal is provided in the hole of the roller. The thread of the suspension bolt will not bite into the inner surface of the hole.

  The roller fitted to the suspension bolt does not contact the left and right plates evenly when moving the moving wall, so it rotates in contact with the plate with the larger frictional force. If it bites into the inner surface of the hole, the roller rises as the roller rotates. As a result, it is impossible to pass through the guide groove of the branch portion (intersection) of the ceiling rail whose width is reduced, but in the present invention, the hard bushing is fitted in the roller hole to prevent the thread from biting in. As a result, the roller is prevented from rising.

  FIG. 1 is a front view showing a general moving wall 1. Suspension wheels 2 and 2 are attached to both sides of the upper end of the moving wall 1, and the suspension wheels 2 and 2 and the moving wall 1 are connected by suspension bolts 3 and 3. The suspension vehicle 2 can be moved by being freely fitted on a ceiling rail laid on the ceiling, and the moving wall 1 can be suspended by the suspension vehicles 2 and 2 and moved together with the suspension vehicles 2 and 2.

  FIG. 2 shows a section of the moving wall 1 suspended from the ceiling rail 4. The suspension wheel 2 is a horizontal wheel model, and the two horizontal wheels 5 a and 5 b are spaced from the suspension bolt 3 by a predetermined distance. And is pivotally supported. The ceiling rail 4 has a running piece 6a on one side wall 7a, and a running piece 6b on the other side wall 7b. The outer periphery of the horizontal wheel 5a is placed on the running piece 6a, and the outer circumference of the horizontal wheel 5b. Is on the traveling piece 6b.

  Since the traveling surfaces of the traveling pieces 6a and 6b are inclined inward, the lower outer periphery of the horizontal wheels 5a and 5b can be rotated in contact with the traveling surface. Since each horizontal wheel 5a is close to the side wall portion 7a and the horizontal wheel 5b is close to the side wall portion 7b, the suspension wheel 2 can move along the ceiling rail 4 without lateral displacement.

  A suspension bolt 3 extending downward from the suspension wheel 2 extends downward through a guide space between both guide portions 8, 8 formed as a part of the ceiling rail 4, and the lower end of the suspension bolt 3 is connected to the moving wall 1. It is fixed. Support portions 9 and 9 projecting outward are provided at the lower ends of the guide portions 8 and 8, and the edges of the ceiling panel are placed on and supported by the support portions 9 and 9.

  Further, upper pressure contact members 10, 10 are provided on both sides of the suspension bolt 3 on the upper portion of the moving wall 1. If the upper pressure contact members 10, 10 are lifted, they are pressed against the support portions 9, 9. The moving wall 1 is fixed. Of course, the lower part of the moving wall 1 is provided with a lower pressure contact member, and the lower end of the moving wall 1 is fixed to the floor surface via the lower pressure contact member. That is, the moving wall 1 is suspended from the ceiling rail 4 and can change its position, and also swings even when placed at a predetermined position. Therefore, the upper pressure contact member 10 and the lower pressure contact member are generally used. Fixed with.

  By the way, plates 11 and 11 are attached to the inner side surfaces of the guide portions 8 and 8 of the ceiling rail 4 along the guide portions 8 and 8, and a roller 12 is fitted to the suspension bolt 3. The material of the plate 11 is urethane rubber, and the roller 12 can also be urethane rubber. Urethane rubber has a high friction coefficient and excellent wear resistance, and friction is generated when the roller 12 contacts the plates 11 and 11. Accordingly, the brake acts on the moving speed of the moving wall 1.

  FIG. 3 shows a specific example of the roller 12 attached to the suspension bolt 3 alone. The roller 12 has an outer diameter D and a height H, and a bush 19 is fitted in a hole 18 having an inner diameter d. The bush 19 is a metal metal bush. A flange 20 is formed on the upper end of the bush 19 and is placed on the upper end of the roller 12. In order to attach to the suspension bolt 3 with the bush 19 fitted, the suspension bolt 3 passes through the bush hole.

  The suspension bolt 3 has a thread on its outer periphery, but this thread is protected by the metal bush 19 fitted in the roller hole and does not bite into the inner peripheral surface of the roller hole. If the moving wall 1 rolls, the outer wall of the roller is sandwiched between the plate 11 and the suspension bolt 3 and the thread bites into the inner peripheral surface of the hole, but this can be prevented.

  Here, the material of the bush is not necessarily limited to a metal, and may be a resin bush as long as it is hard enough to prevent a screw thread from entering. However, since a large impact force acts when the suspension bolt 3 swings together with the moving wall 1, the material must be able to withstand this impact force.

  FIG. 4 is a schematic view of a brake device according to the present invention, showing a cross section. Plates 11 and 11 are fixed to the inner side surfaces 13 and 13 of the guide portions 8 and 8, and a roller 12 is fitted to the suspension bolt 3. Of course, since the bush 19 is fitted in the roller hole 18, the suspension bolt 3 does not directly hit the roller hole 18. The figure shows a state in which the roller 12 is sandwiched between both plates 11, 11. The surfaces 14, 14 of the plates 11, 11 are slightly depressed, and the contact portion of the roller 12 is also slightly depressed.

  Thus, when the roller 12 contacts the plates 11 and 11, a frictional force is generated between the plates 11 and 11 when the roller 12 moves. Incidentally, there is a slight clearance between the plate surfaces 14 and 14 and the roller 12. Or it is a state of clearance 0 and is not a minus clearance.

  When the roller 12 enters between the plates 11, 11, the moving wall 1 rolls and the roller 12 contacts the plate 11. Even if a clearance of 1 mm is provided, it is practically impossible for the roller 12 to pass without contacting the plate 11. Of course, even if the roll does not roll, the suspension bolt 3 is slightly tilted due to the deviation of the core, so that the roller 12 comes into contact with the plate 11.

  If the clearance between the roller 12 and the plates 11 and 11 is a minus clearance, excessive friction is generated when the roller 12 enters the plates 11 and 11, and the moving wall 1 may stop at that position. Here, the size of the clearance is not particularly limited, but generally a clearance of about 0 to 2 mm is suitable.

  Thus, when the moving wall 1 passes, the roller 12 comes into contact with the surface 14 of the plate 11 to generate sliding friction, and a brake acts on the moving wall 1. In this case, the roller 12 having a slight clearance between the plates 11 and 11 does not contact both the plates 11 and 11 at the same time, and slides on the one plate 11 to cause sliding friction. As a result, the roller 12 rotates somewhat due to the frictional force, but the metal bush 19 is fitted in the roller hole 18, so that the thread of the suspension bolt 3 does not bite into the inner peripheral surface. Moreover, the roller 12 does not rise with the rotation.

  FIG. 5 shows a case where the moving wall 1 is suspended by a vertical wheel type suspension wheel 2. The vertical wheel type suspension wheel 2 rotatably supports vertical wheels 16, 16... On both sides and front and rear of a rectangular block main body 15. In the figure, the vertical wheels 16, 16... On both sides roll on the running pieces 17, 17 of the ceiling rail 4, and a roller 12 is fitted to the suspension bolt 3 that hangs downward from the suspension wheel 2. Of course, the bush 19 is also fitted in the hole of the roller 12 so that the thread of the suspension bolt 3 does not bite into the inner peripheral surface of the roller hole.

  And the plates 11 and 11 are being fixed to the inner surface of the guide parts 8 and 8 extended below from the running pieces 17 and 17. FIG. In this case as well, there is a slight dimensional clearance between the plates 11 and 11 and the roller 12, but when the moving wall 1 moves, a roll is generated and the roller 12 becomes a plate. 11 to generate friction.
