Description

The present invention relates to a mobile partition device for partitioning an office, an exhibition hall, a conference hall, etc. into predetermined sections for use.

The moving partition device is a wall surface in which partition panels that are suspended by a suspension body having wheels that can travel on a traveling surface formed on a traveling rail provided on the ceiling and that can move along the traveling rail are connected in a row. It is used for the purpose of partitioning indoor spaces such as offices, exhibition halls, and conference halls into predetermined sections. Further, in order to increase the degree of freedom of layout in the interior space, an intersection where the traveling surfaces of a plurality of traveling rails intersect with each other is formed, and the moving direction of the partition panel is switched at the intersection to form a wall surface by the partition panel. There is a moving partition device that allows the position to be changed.

The moving partition device shown in Patent Document 1 has a moving wall (partition panel) suspended by a crane (suspension support body) capable of traveling along a rail member (running rail) and a plurality of rail members orthogonal to each other. The rail member and the direction changing member are provided with a direction changing member (intersection of traveling rails) to be connected to each other, and a pair of traveling surfaces are formed on the rail member and the direction changing member with a slit portion opened downward. The suspension wheel is arranged on each side surface of the base portion, which holds the upper end portion of the connecting rod connected to the moving wall via the slit portion, the upper plate and the bottom plate fixed above and below the base portion, and the base portion. It is mainly composed of wheels that are installed and can rotate around the horizontal axis.

Further, when the suspension wheel that suspends and supports the moving wall is moved along one rail member and passes through the intersecting portion of the slit portion having a cross shape in a plan view formed on the direction changing member, the wheel of the suspension wheel is formed in the slit portion. In order to prevent the ball from falling into the intersection, hemispherical recesses are formed at each corner of the running surface forming the intersection of the slits, and the upper surface of the ball (sphere) arranged in the recess is exposed. The structure is such that the bottom plate of the suspension wheel rides on the upper surface of the ball by being tumblably held by the ball holding piece in the state of being moved. Furthermore, by interposing a plurality of small balls between the ball and the recess, the ball can easily roll when the suspension vehicle moves on the upper surface of the ball, and the moving direction of the moving wall can be smoothly switched. can.

It is mainly composed of an outer rectangular traveling roller support portion 95c that is pivotally supported, and the traveling roller support portion 95c functions as a vertical spacer between the upper plate 95a and the bottom plate 95b. Further, the upper plate 95a and the bottom plate 95b are formed with notches formed in the substantially central portions of the front, rear, left and right side end portions, which are recessed in a substantially rectangular shape toward the substantially central side of the upper surface view of the upper plate 95a or the bottom plate 95b. Traveling rollers 90A, 90B, 90C, 90D are arranged in the notch.

With reference to FIG. 3, the upper ends of the traveling rollers 90A, 90B, 90C, 90D pivotally supported by the traveling roller support portion 95c project upward from the upper plate 95a of the main body portion 95. Similarly, the lower end protrudes downward from the bottom plate 95b. In this embodiment, although the amount of protrusion upward and downward is the same, the amount of protrusion may be different and is not limited.

Next, the rail unit 3 will be described. As shown in FIG. 1, the rail unit 3 includes a substantially linear horizontal rail 30 extending in the left-right direction and a pair of left-right vertical rails 31 and 32 substantially orthogonal to the horizontal rail 30, and the rails 30, 31, 32, respectively.

The vertical rail 32 on the left side is composed of the rail member 4G, the connecting member 5B, and the rail member 4E in this order from the front to the rear.

Next, the rail member 4A will be described. Since the other rail members 4B, 4C, ..., 4G have substantially the same configuration as the rail member 4A, the description thereof will be omitted or simplified in the following description.

With reference to FIGS. 2 and 3, the rail member 4A is a C-shaped channel member facing downward in the front view by extrusion molding of metal (see FIGS. 1 and 3), and an opening formed substantially in the center of the lower end portion. It has a pair of rail portions 41, 41 formed on the same plane with each other's traveling surfaces 41a sandwiching the portions 40 (see FIG. 2). Further, a pair of left and right guide grooves 43 are formed inside the ceiling wall on the upper side of the rail member 4A, and the guide rollers 91A, 91B, 91C, 91D of the suspension support member 9 can be loosely fitted ( (See FIG. 3).

As shown in FIG. 3, the opening 40 of the rail member 4A is formed so that the connecting rod 92 can be inserted.

Next, the connection member 5A on the right side will be described. Since the connection member 5B on the left side has substantially the same configuration as the rail member 4A, the description thereof will be omitted or simplified in the following description.

With reference to FIGS. 1 to 4, the connecting member 5A includes a rectangular plate-shaped ceiling plate 52 provided above and square columns 56, 56, 56, 56 extending downward from the four corners of the ceiling plate 52, respectively. It is composed of (see FIGS. 2 to 4) and four rectangular plate-shaped rail plates 51, 51, 51, 51 (see FIGS. 2 to 4) fixed to the lower ends of each square support 56. The rail plates 51, 51 adjacent to each other in the left-right or front-rear direction are separated by a certain distance in the left-right or front-rear direction, and openings are formed between the rail plates 51, 51, 51, 51 in a substantially cross shape in the front-rear, front-rear, and left-right directions. The portion 50 is formed. The width of the opening 50 is formed so that the connecting rod 92 can be inserted (see FIG. 3).

Further, as shown in FIG. 3, the straight portion extending in the front-rear direction of the opening 50 communicates with the opening 40 of the rail member 4A in a state where the rail member 4A is connected to the connecting member 5A.

With reference to FIGS. 2 and 3, the separation dimension between the square columns 56 and 56 adjacent to each other in the left-right or front-rear direction is longer than the front-rear dimension or the left-right dimension of the suspension support member 9. Further, the square columns 56, 56, 56, 56 function as spacers between the ceiling plate 52 and the rail plates 51, 51, 51, 51, and the ceiling plate 52 and the rail plates 51, 51, 51, 51 The separation dimension is longer than the vertical dimension of the traveling rollers 90A, 90B, 90C, 90D (see FIG. 3). As a result, the suspension member 9 can pass between the pair of square columns 56, 56 adjacent to each other in the left-right or front-rear direction, and between the ceiling plate 52 and the rail plates 51, 51, 51, 51.

With reference to FIGS. 3 and 4, a pair of left and right guide grooves 53, 53 that are recessed in a substantially rectangular cross-sectional view from the bottom to the top are formed at the lower end of the ceiling plate 52, and the pair of left and right guide grooves 53, 53 extends substantially parallel to each other in the front-rear direction of the ceiling plate 52. Further, although not shown directly, a pair of front and rear guide grooves 53, 53 having substantially the same shape as the pair of left and right guide grooves 53, 53 and substantially orthogonal to the pair of left and right guide grooves 53, 53 are also formed. .. The guide grooves 53, 53, 53, 53 can be loosely fitted with the guide rollers 91A, 91B, 91C, 91D of the suspension support member 9 (see FIG. 3).

Further, as shown in FIG. 3, the pair of left and right guide grooves 53, 53 communicate with the guide grooves 43, 43 of the rail member 4A in a state where the rail member 4A is connected to the connecting member 5A.

As shown in FIGS. 2 to 4, the rail plate 51 includes a traveling surface 51a, and the traveling surface 51a is formed in a plane shape having a substantially L-shape in top view (see FIG. 2). As a result, in the connecting member 5A, the traveling surfaces 51a, 51a, 51a, 51a extending along the horizontal rail 30 and the traveling surfaces 51a, 51a, 51a, 51a extending along the vertical rail 31 intersect ( (See FIG. 2). Further, the traveling surfaces 51a and 51a on the front end side form substantially the same surface as the traveling surfaces 41a and 41a of the rail member 4A in a state where the rail member 4A is connected to the connecting member 5A (see FIG. 3).

Further, as shown in FIGS. 2 and 4, the rail plate 51 has a concave portion that is hemispherically recessed downward from the traveling surface 51a at a corner portion located on the central portion side of the connecting member 5A in view of the upper surface (see FIG. 2). 54, a through hole 55 (see FIG. 4) penetrating from the lower end of the recess 54 to the lower end (outside) of the rail plate 51 is formed, and the recess 54 complements the outer surface 11b of the cap 11 of the ball unit 10 described later. The ball unit 10 can be inserted into the ball unit 10 (see FIGS. 4 and 6). It should be noted that the recess 54 may be inserted as long as the ball unit 10 can be inserted, and it is not necessary to perform precision polishing or quenching on the recess 54 as in the conventional case, so that the manufacturing cost can be suppressed.

Next, the ball unit 10 to be inserted into the recess 54 of the rail plate 51 will be described. With reference to FIGS. 5 and 6, the ball unit 10 is made of a metal formed into a sphere on a bowl-shaped cap 11 (resin receiving material) which is integrally formed by injection formation of a resin and has a small friction coefficient and a hollow inside. It is configured by inserting the ball 15 of the above. Since the cap 11, which is the receiving structure of the ball 15, can be integrally molded, the productivity is good and the manufacturing cost can be suppressed.

As shown in FIGS. 5 and 6, the cap 11 has a hemispherical portion 12 (see FIG. 6) formed in a hemispherical plate shape having substantially the same plate thickness, and a strip-shaped portion arranged in a substantially six-equal arrangement in a top view. 13 (upper end portion of the resin receiving material) (see FIG. 5) is provided, and a slit 14 is formed between the adjacent strip-shaped portions 13, 13. The inner surface 11a of the cap 11 is formed in a continuous spherical shape complementary to the spherical surface of the ball 15.

Further, the substantially vertical inner dimension from the lower end of the inner surface 11a of the cap 11 to the upper end of the strip-shaped portion 13 is formed to be shorter than the diameter which is the maximum diameter of the ball 15 and longer than the radius. The upper end of the ball 15 inserted in the cap 11 is exposed from the cap 11.

The strip-shaped portion 13 has a shape that extends substantially vertically upward from the upper end of the hemispherical portion 12 with substantially the same wall thickness and protrudes toward the inner diameter side and the outer diameter side at the upper end portion to increase the wall thickness. For details, refer to FIG. 6, and in a cross-sectional view, the outer diameter side lower vertical surface extending substantially vertically upward from the outer peripheral surface of the hemisphere portion 12, and the outer diameter direction from the upper end portion of the outer diameter side lower vertical surface. Outer diameter side downward inclined surface that inclines upward and extends linearly, outer diameter side upper vertical surface that extends substantially vertically upward from the upper end of outer diameter side lower inclined surface, upper end portion of outer diameter side upper vertical surface Outer diameter side upward inclined surface extending linearly in the inner diameter direction and upward, inner diameter side upward inclined surface extending linearly in the inner diameter direction and downward from the upper end of the outer diameter side upper inclined surface, inner diameter side One of the inner surfaces 11a of the cap 11 which is provided with an inner diameter-side downwardly inclined surface extending from the lower end of the upwardly inclined surface in the outer diameter direction and curved downward, and the inner diameter side downwardly inclined surface is continuous with the inner peripheral surface of the hemisphere portion 12. It is a department. Further, the outer surface 11b of the cap 11 has a strip-shaped portion 13 having a continuous lower vertical surface on the outer diameter side on the outer peripheral surface of the hemispherical portion 12, and the outer contour is formed in a U-shape in a side view.

Further, the upper end portion of the strip-shaped portion 13 is composed of a part of the above-mentioned outer diameter side lower inclined surface, outer diameter side upper vertical surface, and outer diameter side upper inclined surface, and has an outer diameter from the outer diameter side lower vertical surface. A collar portion 13a projecting to the side is formed.

Next, attachment / detachment of the ball 15 to / from the cap 11 will be described. With reference to FIG. 5, the ball 15 can be inserted into the cap 11 by pushing the ball 15 placed on the inner diameter side upward inclined surface of the strip portion 13 toward the hemisphere portion 12. Specifically, the strip-shaped portion 13 is divided into substantially six equal parts and can be elastically deformed in the outer diameter direction. Since the inner dimension between 13 and 13 in the horizontal direction temporarily expands, the ball 15 can be easily inserted.

Further, when the ball 15 is pushed into the cap 11, the band-shaped portion 13 elastically deforms and expands in the radial direction, after which the maximum diameter portion of the ball 15 is on the inner diameter side composed of the inner diameter side upper inclined surface and the inner diameter side downward inclined surface. By being located below the protruding portion of the ball 15, the elastic deformation of the band-shaped portion 13 of the cap 11 is settled, and the inner surface 11a of the cap 11 is brought into close contact with the spherical surface of the ball 15 to fit the ball 15 into the cap 11. can.

Regarding the state in which the ball 15 is inserted in the cap 11, the inner dimension between the inner diameter side downward inclined surfaces of the opposing strips 13 and 13 in the horizontal direction is shorter than the maximum diameter of the ball 15. Therefore, it is possible to prevent the ball 15 from coming out and hold it.

Further, in order to take out the ball 15 from the inside of the cap 11, the strip-shaped portion 13 can be taken out by elastically deforming in the outer diameter direction and temporarily expanding the dimension in the inner diameter direction. As described above, when the ball 15 is inserted into the cap 11, the band-shaped portion 13 holds the ball 15 in the gripped state, so that the ball 15 is prevented from being unintentionally pulled out from the cap 11.

Next, attachment / detachment of the ball unit 10 to / from the recess 54 of the connecting member 5A will be described. With reference to FIG. 6A, the ball unit 10 is inserted into the recess 54, and the lower end of each crossguard 13a of the cap 11 is brought into contact with the traveling surface 51a of the connecting member 5A in a circumferential shape. The ball unit 10 can be easily inserted into the recess 54 in the positioned state. That is, the collar portion 13a can prevent the ball unit 10 from being tilted and inserted.

Further, as shown in FIG. 6A, since the crossguard portion 13a protrudes upward from the traveling surface 51a in the state of being mounted on the recess 54, the crossguard portion 13a is inserted from the start to the completion of the insertion work. Since the work can be performed by gripping, the insertion work is easy and the positioning is also easy to be stable.

With reference to FIGS. 2 and 3, the dimensions between the outer ends of the ball units 10 and 10 adjacent to each other in the left-right or front-rear direction are the inner ends of the pair of left-right traveling rollers 90B and 90D or the pair of front-rear traveling rollers 90A and 90C. The traveling rollers 90A, 90B, 90C, and 90D are arranged to be shorter than the dimension between them, and can travel on the traveling surface 51a of the rail plate 51 without contacting the ball unit 10.

Further, referring to FIG. 3, the protruding dimension of the ball 15 from the traveling surface 51a of the rail plate 51 in the state where the ball unit 10 is mounted in the recess 54 is such that the lower ends of the traveling rollers 90A, 90B, 90C, 90D are used. The dimensions are substantially the same as the dimensions protruding downward from the bottom plate 95b of the main body 95.

Further, in the ball unit 10 inserted in the recess 54, since the cap 11 is stopped by the collar portion 13a, it is possible to prevent the ball 15 and the cap 11 from rotating together. In addition, the recess 54 has a shape complementary to the outer surface 11b of the cap 11 whose outer contour is formed in a U-shape in a side view, and is in surface contact with the outer surface 11b of the inserted cap 11. Therefore, the cap 11 is prevented from rotating around the horizontal axis.

Further, since the recess 54 has a shape complementary to the outer surface 11b of the cap 11 and is in surface contact with the outer surface 11b of the inserted cap 11, the outer shape of the cap 11 is held by the recess 54. Therefore, it is possible to prevent deformation of the spherical shape on the inner surface 11a of the cap 11. Similarly, elastic deformation of the strip portion 13 in the outer diameter direction can be prevented.

As shown in FIG. 6B, when the ball unit 10 is taken out from the recess 54, the rod 6 is inserted from below the through hole 55 of the connecting member 5A, and the ball unit 10 is easily taken out by pushing up from below. be able to. This facilitates maintenance work.

Further, as shown in FIG. 3, the outer dimensions of the cap 11 are shorter than the width of the openings 40 of the rail members 4A, 4B, ..., 4G and the openings 50 of the connecting members 5A, 5B. Since the ball unit 10 can be taken out through the opening 40 or the opening 50, maintenance and repair are easy.

As described above, since it is easy to grip the crossguard 13a in the state where the ball unit 10 is inserted into the recess 54, the crossguard 13a is gripped and the ball unit 10 is taken out from the recess 54. You may.

Next, the movement of the suspension member 9 will be described based on an example of moving from the rail member 4B along the horizontal rail 30 to the rail member 4D via the connecting member 5A. The duplicated explanation will be omitted or simplified.

With reference to FIG. 2, the suspension member 9 is suspended and supported on the rail member 4B by placing a pair of front and rear traveling rollers 90A and 90C on the traveling surfaces 41a and 41a of the rail member 4B. By pushing the partition panel 2 (see FIG. 1) to the left on the paper surface, the traveling rollers 90A and 90C roll on the traveling surfaces 41a and 41a and move to the left along the horizontal rail 30.

At this time, since the pair of left and right traveling rollers 90B and 90D are located on the opening 40 of the rail member 4B, they are prevented from hindering their movement.

Further, when the guide rollers 91A, 91B, 91C, 91D come into contact with the inner walls of the guide grooves 43, 43 (see FIG. 3) of the rail member 4B, the movement of the suspension member 9 is guided and the partition panel 2 is guided. Shaking and tilting are prevented.

As shown in FIG. 7A, in the suspension member 9 moving to the left side, a pair of front and rear traveling rollers 90A and 90C are front and rear of the right end portion of the connecting member 5A from the traveling surfaces 41a and 41a of the rail member 4B. As shown in FIG. 7B, the bottom plate of the main body 95 of the suspension member 9 is transferred onto the pair of traveling surfaces 51a and 51a and further moved to the left on the traveling surfaces 51a and 51a. 95b comes into contact with the upper surfaces of the balls 15 and 15 of the pair of front and rear ball units 10 and 10 arranged at the right end of the connecting member 5A. For convenience of explanation, the square columns 56 and 56 on the front side are not shown in FIG. 7.

At this time, the impact due to the contact between the suspension member 9 and the ball 15 is received by the elastic force of the cap 11, and the impact is buffered between the ball 15 and the cap 11, so that the suspension support generated by this contact is generated. The vibration of the material 9 and the ball 15 is absorbed. Similarly, the impact generated between the ball 15 and the cap 11 is also buffered by the elastic force of the cap 11. Therefore, it is possible to reduce the noise and vibration transmitted through the partition panel 2 and the connecting member 5 based on the vibration of the suspension member 9 and the ball 15 itself.

Further, as described above, since the inner surface 11a of the cap 11 is in close contact with the spherical surface of the ball 15, an impact is less likely to occur between the ball 15 and the cap 11.

Further, since the ball 15 is covered near the upper surface of the ball 15 by the band-shaped portion 13 of the cap 11, it is difficult for the impact sound when the suspension member 9 is transferred to the upper surface of the ball 15 to escape to the outside. In addition to this, since the upper end portion of the strip-shaped portion 13 is exposed from the traveling surface 51a of the rail plate 51, the cap 11 can also absorb and buffer the vibration of the surrounding air. That is, it also functions as a sound absorbing material.

Further, as described above, the upper end of the ball 15 protrudes from the running surface 51a by substantially the same dimension as the lower end of the running rollers 90A, 90B, 90C, 90D protrudes from the bottom plate 95b of the main body 95. , The height difference between the upper end of the ball 15 and the lower end surface of the bottom plate 95b is unlikely to occur. As a result, when the partition panel 2 is pushed to move the suspension member 9 to the left side, the pair of front and rear traveling rollers 90A and 90C remain in contact with the traveling surfaces 51a and 51a of the rail plates 51 and 51. , The bottom plate 95b of the main body 95 rides on the balls 15 and 15 that are in contact with each other.

Further, when the partition panel 2 is pushed to move the suspension member 9 to the left side, the connecting rod 92 of the suspension member 9 is arranged at the center of the connecting member 5A as shown in FIG. 7 (c). In the suspension member 9, each corner of the bottom plate 95b of the main body 95 is transferred onto the ball 15 of the ball unit 10, and the traveling rollers 90A, 90B, 90C, 90D are above the opening 50 of the connecting member 5A. It is held at a height position substantially the same as when it is placed on the traveling surface 51a.

With the connecting rod 92 of the suspension member 9 arranged at the center of the connecting member 5A, the partition panel 2 is pushed to the left to push the pair of front and rear traveling rollers 90A and 90C to the left side of the connecting member 5A. Transfer onto a pair of front and rear traveling surfaces 51a, 51a at the end.

Further, when the partition panel 2 is pushed to the left, the suspension support member 9 has a pair of left and right traveling rollers 90A and 90C transferred to the traveling surfaces 41a and 41a of the rail member 4D. In this way, the suspension member 9 can be moved along the rail unit 3.

If the protruding dimension of the ball 15 is relatively large due to design tolerances and aged use, the bottom plate 95b will be transferred to the ball 15 after the bottom plate 95b comes into contact with the vicinity of the upper end of the ball 15 from the side. However, even in this case, vibration and sound can be reduced by the cap 11. Similarly, when the protruding dimension of the ball 15 is relatively small, when the pair of left and right traveling rollers 90A and 90C approach the opening 50, the bottom plate 95b abuts on the bottom plate 95b from above the upper end of the ball 15 and is transferred to the ball 15. However, even in this case, vibration and sound can be reduced by the cap 11.

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

For example, in the above embodiment, the inner surface 11a of the cap 11 has been described as having a continuous spherical shape complementary to the spherical surface of the ball 15, but the present invention is not limited to this, and the spherical surface of the sphere is formed by a set of a plurality of lines or points. A spherical shape complementary to the above may be formed.

Further, although the cap 11 has been described as a mode in which the outer contour is formed in a U-shape in a side view, the cap 11 is not limited to this, and may be in a rectangular shape in a side view. In this embodiment, the concave portion can be formed in a rectangular shape when viewed from the side according to the outer shape of the cap, and the cap 11 itself can regulate the rotation with a simple structure.

Further, the cap 11 has been described as being inserted into a recess 54 that is hemispherically recessed downward from the traveling surface 51a, but the present invention is not limited to this, and the support portion that projects upward from the traveling surface 51a and can hold the cap 11. May be formed, and is not limited. Further, the holding of the cap 11 may be fixed to the rail plate 51 by fixing the cover covering the upper end portion of the cap 11 to the rail plate 51, and the holding is not limited to the insertion.

The band-shaped portion 13 has been described as being divided into substantially six equal parts by slits 14, 14, ..., But the present invention is not limited to this, and the strip-shaped portion 13 may be formed in four equal parts or eight equal parts, and is elastically deformed. It may be changed as appropriate to balance ease of use and support strength. Further, the strip-shaped portion may be continuous in the circumferential direction without forming a slit.

Although the recess 54 has been described as having a shape complementary to the outer surface 11b of the cap 11, the inner dimension in the horizontal direction may be slightly shorter than the outer dimension of the cap 11. .. In this embodiment, when the cap is inserted, the cap is pressed in the inner diameter direction, and an elastic recovery force is generated in the cap. Therefore, the holding force of the cap with respect to the concave portion can be increased and the cap can be held. Since the inner dimension in the horizontal direction is narrowed, the holding force of the ball 15 is also improved.
