[0011] At least one of the members or parts described with a reference symbol is provided, unless otherwise specified by "one". In other words, unless otherwise specified by "one", the member may be provided in two or more. The partition stand shown in the present disclosure includes at least the components such as the members or parts described with a reference symbol, as well as the structural parts shown in the drawings.

[0012] (First embodiment) <1. Overview of Partition Stand> In this embodiment, as shown in FIG. 1, an example of a partition stand according to the present disclosure is applied to a partition stand 10 to which a belt partition 1 can be attached.

[0013] The belt partition 1 comprises a belt 2 for dividing a space and a take-up drum (not shown) for winding up the belt 2, and is used when determining "the direction people are lining up" or "territory marking", etc.

[0014] Fig. 1 shows an example of use in the case of "tie-up". Specifically, belt partitions 1 are attached to the upper ends of multiple partition stands 10, and the belts 2 of each belt partition 1 are connected to other partition stands 10.

[0015] <2. Configuration of the partition stand> <2.1 Overview of the partition stand> 2, the partition stand 10 includes at least a columnar pole 11 and a base 12. The pole 11 according to this embodiment is made of a hollow pipe material.

[0016] An attachment portion (not shown) to which the belt partition 1 can be detachably attached is provided at the upper end of the pole 11. The lower end of the pole 11 is fixed to a base 12. The base 12 holds the pole 11 in an upright position.

[0017] 3, at least one (in this embodiment, multiple) swivel caster 13 is provided on the underside of base 12. At least one of the multiple (in this embodiment, three) swivel casters 13 is provided with a locking device 14 (see FIG. 4).

[0018] <2.2 Details of the pedestal> 5, the base 12 is configured to include a weight portion 12A and a cover 12B. The weight portion 12A is a plate-shaped weight for preventing the partition stand 10 from falling over. A plurality of swivel casters 13 are fixed to the weight portion 12A.

[0019] The cover 12B is a covering member that covers the upper surface side of the weight portion 12A. The cover 12B according to this embodiment is detachably attached to the weight portion 12A by utilizing magnetic attraction. For this reason, in this embodiment, the cover 12B is made of metal, and a plurality of permanent magnets 12C are fixed to the outer periphery of the weight portion 12A.

[0020] <2.3 Swivel caster details> The three swivel casters 13 have the same configuration, except for the presence or absence of a locking device 14. Specifically, as shown in Fig. 6, each swivel caster 13 is configured to include a wheel 13A, a fork 13B, and a housing 13C.

[0021] The wheel 13A is a rotating body. The wheel 13A according to this embodiment is a cylindrical roller-shaped rotating body, and axles 13D are provided on one end side and the other end side in the central axis direction. The fork 13B is a member that supports each axle 13D and is rotatable with respect to the base 12.

[0022] In addition, the fork 13B according to this embodiment is connected to the housing 13C in a manner that allows it to turn while being housed in the housing 13C that is configured in a substantially cup shape. The housing 13C is fixed to the weight portion 12A by press-fitting or the like.

[0023] The pivot axis L1 of the fork 13B and the central axis L2 of the axle 13D are in a twisted relationship (see FIG. 4). Therefore, when the wheel 13A rotates and the base 12 moves in parallel, the fork 13B pivots so that the central axis L2 is located on the backward side of the pivot axis L1.

[0024] <2.4 Details of the locking device> The locking device 14 is a device that can switch between a locked state (see FIG. 7) that restricts the rotation of the wheel 13A and an unlocked state (see FIG. 4) in which the locked state is released. Specifically, the locking device 14 is configured to have at least a stopper 14A and a handle portion 14B.

[0025] The stopper 14A is a member that locks the wheel 13A by contacting the wheel 13A with a predetermined contact pressure or more (see FIG. 7). The stopper 14A is disposed at the center of rotation of the fork 13B and is displaceable in a direction parallel to the central axis L1 of rotation of the fork 13B.

[0026] Specifically, as shown in Fig. 8, the stopper 14A is a substantially cylindrical member and has at least a stopper main body 14C and a contact portion 14D, etc. The stopper main body 14C is a member made of resin or metal.

[0027] At least one (in this embodiment, multiple) radially protruding protrusion 14E is provided on the outer circumferential surface of the stopper body 14C. Each protrusion 14E according to this embodiment is formed of a fin-shaped protrusion extending along the longitudinal direction of the stopper body 14C.

[0028] A through hole (not shown) through which the stopper body 14C can pass is provided at a portion of the housing 13C that corresponds to the rotation center of the fork 13B. The stopper body 14C is slidably inserted into the through hole.

[0029] A groove (not shown) into which the protrusion 14E is slidably fitted is provided on the inner peripheral surface of the through hole. The groove extends in a direction parallel to the central axis L1 of rotation. Therefore, the stopper 14A can slide in a direction parallel to the central axis L1 of rotation while being restricted from rotating around the central axis L1 of rotation.

[0030] The contact portion 14D is made of a softer material than the stopper body 14C, such as rubber, and is a portion that comes into contact with the wheel 13A in the locked state. The contact portion 14D is provided at one end of the stopper body 14C in the longitudinal direction. Incidentally, the contact portion 14D according to this embodiment is fixed to one end of the stopper body 14C by fastening means such as a small screw.

[0031] At least one (in this embodiment, a plurality) spiral grooves 14F are provided on the other longitudinal end side of the stopper 14A. And, as shown in FIG. 4, the handle portion 14B is provided with a protrusion 14G slidably fitted into the groove 14F.

[0032] The handle portion 14B is a member that is rotated by a user. The handle portion 14B is restricted in displacement in a direction parallel to the pivot axis L1 by a restricting plate 14H (see FIG. 5), and is rotatable about the pivot axis L1.

[0033] As a result, when the handle portion 14B is rotated, the stopper 14A is displaced in a direction parallel to the central axis of rotation L1. In other words, when the handle portion 14B is rotated approximately 90 degrees from the state shown in Fig. 7, the stopper 14A is displaced due to the screw principle to the state shown in Fig. 4.

[0034] <3. Features of the Partition Stand According to the Present Embodiment> The partition stand 10 according to this embodiment includes a locking device 14 that can switch between a locked state that restricts the rotation of the wheels 13A and an unlocked state in which the locked state is released. This makes it possible to easily move the partition on the partition stand 10 without impairing the original function of the partition.

[0035] Stopper 14A is disposed at the center of rotation of fork 13B and is displaceable in a direction parallel to the rotation center axis L1 of the fork. As a result, locking device 14 projected onto a horizontal plane is housed within swivel caster 13 projected onto the horizontal plane. In other words, locking device 14 according to this embodiment fits compactly into swivel caster 13.

[0036] (Other embodiments) In the above-described embodiment, the configuration includes three swivel casters 13 and one locking device 14. However, the present disclosure is not limited to this. That is, the present disclosure may include, for example, a configuration including one swivel caster 13 and one locking device 14, or a configuration including three swivel casters 13 and three locking devices 14.

[0037] The stopper 14A according to the above embodiment is disposed at the center of rotation of the fork 13B. However, the present disclosure is not limited to this. That is, the stopper 14A may be disposed at a position offset from the center of rotation as long as the stopper 14A is in contact with the wheel 13A.

[0038] In the above embodiment, the handle portion 14B is rotated to switch between the locked state and the unlocked state. However, the present disclosure is not limited to this. That is, the present disclosure may be configured to switch between the locked state and the unlocked state by using, for example, a knock cam mechanism.

[0039] The contact portion 14D according to the embodiment described above is made of rubber. However, the present disclosure is not limited to this. That is, the contact portion 14D may be made of a material other than rubber as long as it can restrict the rotation of the wheel 13A.

[0040] The stopper 14A according to the above embodiment is substantially cylindrical. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that the stopper is, for example, a rotary cam that switches between a locked state and an unlocked state.

[0041] Furthermore, the present disclosure is not limited to the above-mentioned embodiments as long as it is consistent with the gist of the disclosure described in the above-mentioned embodiments. Therefore, the present disclosure may be a configuration in which at least two of the above-mentioned embodiments are combined, or a configuration in which any of the components illustrated or the components described with reference numerals in the above-mentioned embodiments are eliminated.
