Description

  The present invention relates to partitions.

Conventionally, as shown in Patent Document 1 below, a partition having a base and a plurality of foldable panels is known. In this partition, a traveling body such as a caster is attached to a base, and the entire partition can be moved in a state where a plurality of panels are folded.
In this type of partition, generally, the mass of the base is relatively large in order to stabilize the posture when the panel is expanded.

Unexamined-Japanese-Patent No. 4-272351

By the way, in this type of partition, it is required to make it easy to move the partition in a folded state of the panel. In order to meet such requirements, the center of swing of the first panel located closest to the base side is offset from the center position of the base in the width direction of the panel in the folded state, so that the center of gravity of the panel and the base It is conceivable to bring the center of gravity closer.
However, when the swing center of the first panel is shifted from the center position of the base as described above, the posture of each panel when the panels are expanded tends to be unstable.

  The present invention has been made in consideration of such circumstances, and it is an object of the present invention to provide a partition capable of further stabilizing the posture of each panel in the unfolded state.

  In order to solve the above problems, the partition according to the first aspect of the present invention is between a folded state in which the panel faces face each other and an expanded state in which the angle between the panel faces is expanded from the folded state. A plurality of panels which can be changed in position, and a swing support portion fixed to the base and swingably supporting the first panel located closest to the base among the plurality of panels; And the swing support portion is a first end portion on one side in the panel width direction of the first panel when the direction in which the first panel extends in the folded state is the panel width direction in top view When it is positioned on the one side in the panel width direction with respect to the central portion of the base in the panel width direction, when viewed in a direction orthogonal to the panel width direction, The second end of the other side of the panel width direction of the panel, in the deployed state than the central portion of the panel width direction of the base are positioned on the other side of the panel the width direction.

  According to the first aspect, when each panel is in the unfolded state, the first panel is arranged to straddle the central portion of the base in the panel width direction. In this manner, by arranging the first panel to straddle the center of gravity of the large-mass foundation in the panel width direction, the moment acting on the foundation when the first panel attempts to fall in the panel width direction is reduced. , The posture of each panel can be stabilized.

  Here, the swing support portion is disposed in a pair so as to sandwich the first panel in the vertical direction, and the pair of swing support portions respectively swings the first panel with respect to the base by a predetermined amount or more. An angle limiting portion for regulating may be provided.

  In this case, when the operation to bring the first panel into the unfolded state is performed by restricting the swing angle of the first panel with respect to the base by the angle limiting portions respectively provided to the pair of upper and lower swing support portions. The force applied to the first panel or the swing support can be dispersed. Therefore, it is possible to suppress the application of a large force locally to the first panel or the swing support portion, and it is possible to further stabilize the posture of each panel while enhancing the strength of the partition.

  In the top view, a length from the center of swing of the first panel with respect to the base to the second end is a, and a center of the base in the panel width direction and the center of swing A> b> 0 and θ ≦ arc cos (b / a), where b is the distance in the panel width direction between them, and θ is the maximum angle of the first panel with respect to the panel width direction that the angle limiting unit permits. ) May be satisfied.

  By designing each dimension of the partition so as to satisfy a> b> 0 and θ ≦ arc cos (b / a), the second end of the first panel, which becomes a free end in swinging with respect to the base, It can be located on the other side in the panel width direction than the central portion of the base in the width direction.

  In addition, when the plurality of panels are in the expanded state, a straight line connecting end portions on one side in the panel width direction of the panels excluding the first panel among the plurality of panels in top view Is a straight line L1 and the straight line connecting the end portions on the other side in the panel width direction is a straight line L2, the second end of the first panel in the unfolded state is the straight line L1 and the straight line L2. Or on the straight line L2.

  In this case, in the unfolded state, the second end of the first panel, which is a free end in the swinging movement with respect to the base, is positioned within the range where the plurality of panels are positioned in the panel width direction. It can be stabilized reliably.

  According to the present invention, it is possible to provide a partition capable of further stabilizing the posture of each panel in the unfolded state.

It is a perspective view in the unfolded state of the partition concerning this embodiment. It is a top view of the partition of FIG. It is a front view of the partition of FIG. FIG. 5 is a top view of the partition in a folded state. (A) is an upper side figure of the rocking | fluctuation support part vicinity of FIG. (B) is a front view of (a). It is an enlarged view of FIG.

(Swing support)
The pair of rocking support portions 22 have the same configuration as each other. Hereinafter, the configuration of the upper swing support portion 22 will be described by representing the pair of swing support portions 22 as a representative. As shown in FIG. 5B, the lower surface of the upper swing support portion 22 is formed with a recess 22a that is recessed upward. The concave portion 22 a is formed from the end on the −X side of the rocking support portion 22 to the central portion in the orthogonal direction of the rocking support portion 22. The swing support portion 22 is provided with an angle limiting portion 22b that limits the swing of the first panel 40A with respect to the base 10 by a predetermined amount or more. As shown in FIG. 5A, the angle limiting portion 22b of the present embodiment is a part of the inner surface of the recess 22a, and extends toward the -X side gradually toward the -Y side and toward the + Y side. It is an inclined surface. The rocking support portion 22 is provided with a pin P extending in the vertical direction. At least a portion of the pin P is located in the recess 22a, and the lower end of the pin P is loosely fitted in a hole (not shown) of the first panel 40A. With this configuration, the swing support portion 22 swingably supports the first panel 40A, and the central axis of the pin P is the swing center of the first panel 40A.

  Further, in FIG. 5A, the first panel 40A in the unfolded state is indicated by a solid line, and the first panel 40A in the folded state is indicated by a two-dot chain line. As shown by the solid line in FIG. 5A, when the first panel 40A is in the unfolded state, an upper frame 43 described later of the first panel 40A abuts on the angle limiting portion 22b. With this configuration, the angle limiting portion 22b regulates the swing of the first panel 40A with respect to the base 10 by a predetermined amount or more.

As described above, each rocking support portion 22 is formed with a recess 22a recessed from the inner end surface in the vertical direction toward the outer side in the vertical direction, and at least a part of the inner surface of the recess 22a is on the -Y side. The angle limiting portion 22b extends gradually toward the −X side as it moves toward the + Y side. Further, each swing support portion 22 is provided with a pin P extending in the vertical direction, and the inner end in the vertical direction of the pin P is loosely fitted in a hole (not shown) of the first panel 40A. With this configuration, the pair of swing support portions 22 swingably supports the first panel 40A.
In addition, the structure of the rocking | swiveling support part 22 is not limited above. For example, the swing support portion 22 may have a hinge or the like that swingably connects the first panel 40A to the offset member 21.

(Panel group)
As shown in FIG. 1, the panels 40A to 40C are connected in a bellows shape, and are configured to be deployable in the orthogonal direction. A caster 50 is provided on a lower end portion of at least a part of the panels 40A to 40C via a shaft 51.
The first panel 40 </ b> A is located closest to the base 10 in the panel group 30. The first panel 40A is swingably supported by the swing support portion 22 with respect to the base 10 and the support 20. The swing support portion 22 supports a first end 46 (see FIG. 6) on the −Y side of the first panel 40A. The first panel 40A and the second panel 40B, the second panel 40B and the sub panel 40C, and the sub panel 40C are pivotably connected to each other by a hinge (not shown).

  Since each of the panels 40A to 40C has the same configuration, the configuration of the first panel 40A will be described by representing the panels 40A to 40C. As shown in FIG. 3, the first panel 40 </ b> A includes a frame 41 formed in a rectangular frame shape, and a panel main body 42 fitted in the frame 41. The frame 41 includes an upper frame 43, a pair of vertical frames 44, and a lower frame 45. The upper frame 43 is located above the panel body 42, and the lower frame 45 is located below the panel body 42.

The pair of vertical frames 44 extends in the vertical direction, and connects both ends of the upper frame 43 and the lower frame 45 in the panel width direction.

  As shown in FIG. 1, the sub operation unit 70 is provided on the sub panel 40 </ b> C located closest to the −X side in the panel group 30. The sub operation unit 70 includes a gripping portion 71 extending in the vertical direction, and a pair of connecting portions 72 connecting the upper and lower end portions of the gripping portion 71 and the sub panel 40C. The sub operation unit 70 may be the same type of component as the operation unit 60. For example, in a state where the locking mechanism of each caster 50 provided on the base 10 is operated to fix the base 10, the panel group 30 can be expanded by gripping the sub operation unit 70 and pulling it to the -X side. .

  Here, the dimensional relationship of each part of the partition 1 of this embodiment will be described with reference to FIG. 6 which is a top view showing a case where the panel group 30 is in the expanded state. An alternate long and short dash line (hereinafter referred to as a center line C) shown in FIG. 6 is a straight line passing through the center of the base 10 in the panel width direction and extending in the orthogonal direction. As shown in FIG. 6, in the top view, the second end 47 on the + Y side of the first panel 40A is located on the + Y side of the center line C. Therefore, when viewed from the orthogonal direction orthogonal to the panel width direction, the second end 47 in the unfolded state is located on the + Y side of the central portion in the panel width direction of the base 10. On the other hand, the first end 46 on the -Y side of the first panel 40A is located on the -Y side relative to the center line C. That is, the first panel 40A is arranged to straddle the center line C in the panel width direction. The center line C is a straight line passing the center of the base 10 in plan view along a direction perpendicular to the direction in which the longitudinal beam portion 11 of the base 10 extends.

  In FIG. 6, the dimension a is a length from the swing center (central axis of the pin P) with respect to the base 10 of the first panel 40A to the second end 47 of the first panel 40A. The dimension b is a distance in the panel width direction from the center line C to the swinging center. The angle θ is the maximum angle with respect to the panel width direction of the first panel 40A that the angle limiting unit 22b allows. In the present embodiment, the angle limiting portion 22b, which is an inclined surface, is inclined at an angle θ with respect to the panel width direction.

Here, the above a, b and θ satisfy the following equations (1) and (2).
a>b> 0 (1)
θ ≦ arccos (b / a) (2)
Equations (1) and (2) are requirements for the second end 47 of the first panel 40A in the unfolded state to be located on the + Y side of the center line C.

  Further, as shown in FIG. 2, in a top view, a straight line connecting the end portions on the -Y side of the panels 40B and 40C in the unfolded state is L1, and a straight line connecting the end portions on the + Y side is L2. At this time, the second end 47 of the first panel 40A in the unfolded state is located between the straight line L1 and the straight line L2 or on the straight line L2 in top view.

  Next, the operation of the partition 1 configured as described above will be described.

  When the panel group 30 is expanded, the angle limiting portion 22b is placed on the + Y side of the base 10 so that the second end 47 is positioned on the + Y side of the center in the panel width direction of the base 10 when viewed from the orthogonal direction. 1 Regulating the swing of the panel 40A by a predetermined amount or more. Therefore, when the panel group 30 is in the unfolded state, the first end 46 of the first panel 40A is located on the -Y side of the center line C in top view, and the second end 47 of the first panel 40A is It is located on the + Y side of the center line C. That is, the first panel 40A is disposed so as to straddle the center line C in the panel width direction. As described above, the first panel 40A acts on the base 10 when the first panel 40A attempts to fall in the panel width direction by arranging to straddle the center of gravity of the base 10 having a large mass in the panel width direction. The moment is reduced. Therefore, the attitude of the first panel 40A and the attitudes of the panels 40B and 40C connected to the first panel 40A can be stabilized.

  In addition, by restricting the swing angle of the first panel 40A with respect to the base 10 by the angle limiting portions 22b respectively provided to the pair of upper and lower swing support portions 22, an operation for bringing the first panel 40A into the unfolded state is performed. When it is received, the force applied to the first panel 40A or the swing support portion 22 can be dispersed. Therefore, the application of a large force locally to the first panel 40A or the swing support portion 22 is suppressed, and the posture of each of the panels 40A to 40C can be further stabilized while the strength of the partition 1 is increased.

  Further, the swing support portion 22 swingably supporting the first panel 40A is disposed at a position apart from the central portion of the base 10 in the panel width direction in the panel width direction. Thus, as described above, the center of gravity of the panel group 30 and the center of gravity of the base 10 may be arranged at the same position in the panel width direction while making the first panel 40A substantially the same width as the other panels 40B and 40C. It becomes possible. This can improve the stability when moving the partition 1.

  Further, by designing each dimension so as to satisfy θ ≦ arccos (b / a), the second end 47 of the first panel 40A, which is a free end in the swinging with respect to the base 10, is It can be located on the + Y side.

  Further, the second end 47 of the first panel 40A in the unfolded state is located between the straight line L1 and the straight line L2, or on the straight line L2. As a result, the second end 47 of the first panel 40A, which is a free end in swinging with respect to the base 10, is positioned within the range in which the sub panel 40C in the unfolded state is positioned in the panel width direction. The posture of 40 C can be stabilized more reliably.

  Further, in the present embodiment, the widths of the first panel 40A, the second panel 40B, and the plurality of sub panels 40C are substantially equal to one another. For this reason, it is possible to make the components constituting these panels 40A to 40C common while making the appearance of the first panel 40A similar to the appearance of the second panel 40B and the subpanel 40C. Therefore, the manufacturing cost of the partition 1 can be reduced.

  Further, a pair of swing support portions 22 is disposed to sandwich the first panel 40A in the vertical direction, the upper end portion and the lower end portion of the support 20 extend in the panel width direction, and the pair of swing support portions 22 A pair of supporting offset members 21 are provided. According to this configuration, the first panel 40A can be swingably connected to the support column 20, and the appearance of the first panel 40A can be made equal to the appearance of the other panels 40B and 40C.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

  For example, although the partition 1 of the said embodiment is equipped with five subpanels 40C, the number of subpanels 40C can be changed suitably. For example, the sub panel 40C may not be provided, or four or less or six or more sub panels 40C may be provided.

  In addition, it is possible to replace components in the above-described embodiment with known components as appropriate without departing from the spirit of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
