Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt partition stand for regulating passages by stretching partition belts drawn out from a head body between them.

2. Description of the Related Art Conventionally, in various facilities such as financial institutions and event venues, belt partition stands have been used to regulate passages for pedestrians. A belt partition stand generally includes a pedestal to be placed on the floor, a pillar standing from the pedestal, and a head body connected to the upper end of the pillar (see Patent Document 1, for example). In the belt partition stand disclosed in Patent Document 1, the head body (second pipe 4) houses a partition belt (21) wound around a winding shaft (21) in a payable state, as shown in FIG. 1 of the same document. The partition belt (21) is biased in the winding direction by biasing means (spiral spring 23). The head body is in the form of a closed case with an opening (belt lead-out portion 22) for letting out the partition belt (21).

When using the belt partition stand, the partition belt (21) is let out and the belt end (29) provided at the tip of the belt is engaged with the belt end receiving part (32) provided on the head body of another belt partition stand. As a result, the partition belt (21) is stretched between the adjacent belt partition stands, and the passage of pedestrians can be regulated.

However, the above-mentioned conventional belt partition stand is intended for indoor use, and outdoor use is not considered. For this reason, for example, when the belt partition stand is used outdoors in the rain and the partition belt containing moisture is wound around the head body, the water enters the inside of the head body. Also, water may enter the interior of the head body through the opening for the belt formed in the head body. As a result, the moisture inside the head body is not easily discharged and stays inside the head body, which may lead to problems such as the occurrence of rust in the constituent parts of the head body.

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

1 to 9 show an example of a belt partition stand according to the invention. A belt partition stand A1 of this embodiment includes a pedestal 1, a support 2 standing from the pedestal 1, a head body 4 connected to the support 2, a partition belt 5, and a belt end 6 provided at the tip of the partition belt 5.

The pedestal 1 is a member to be placed on the floor surface or the ground, and has a substantially truncated cone shape. The strut 2 is formed in a cylindrical shape. The details of the connection structure between the base 1 and the support 2 will be described later.

The head body 4 is connected to the upper end of the support 2 and can accommodate the partition belt 5 . The head body 4 includes a tubular portion 41 , a ceiling portion 42 , a connecting portion 43 and a belt support unit 44 . The cylindrical portion 41 has a substantially cylindrical shape, and has an open top end and a bottom end. As shown in FIGS. 1, 3, 7, etc., the tubular portion 41 as a whole is formed such that the cross-sectional dimension thereof decreases downward.

A belt opening 411 and a plurality of belt end receiving portions 412 are formed in the cylindrical portion 41 . The belt opening 411 is an opening through which the partition belt 5 is passed, and has a slit shape extending in the vertical direction. As understood from FIGS. 3, 5, etc., the upper end of the belt opening 411 is open. The plurality of belt end receiving portions 412 are positioned at three positions shifted by 90° in the circumferential direction of the cylindrical portion 41 with respect to the belt opening 411 . Each belt end receiving portion 412 is formed to have a substantially T-shaped cross section so as to extend for a certain length along the axial direction of the cylindrical portion 41 .

The ceiling portion 42 is arranged above the tubular portion 41 and covers the upper end opening of the tubular portion 41 . The ceiling portion 42 has a relatively large plan view size, and as shown in FIGS. 2 and 7, overlaps the entire tubular portion 41 (the tubular body portion excluding the belt end receiving portion 412) when viewed in the vertical direction. The upper surface of the ceiling portion 42 bulges upward at the center in a plan view and descends toward the periphery.

The connecting portion 43 is arranged below the cylindrical portion 41 . The connecting portion 43 has a cylindrical shape, and has an open top end and a bottom end. The connecting portion 43 has a cylindrical portion 431 formed in a cylindrical shape at its lower portion. An upper portion of the connecting portion 43 is tapered such that the diameter of the connecting portion 43 decreases downward. The cylindrical portion 431 is a portion connected to the upper end of the support 2 . The details of the connecting structure between the column 2 and the cylindrical portion 431 (connecting portion 43) will be described later.

The belt support unit 44 is arranged inside the cylindrical portion 41 and supports the wound partition belt 5 . More specifically, as shown in FIGS. 3-7, belt support unit 44 includes cylindrical housing 45 and reel 46 .

The cylindrical housing 45 has a substantially bottomed cylindrical shape and has a plurality of belt passage grooves 451 and 452 and a bottom plate 453 . As shown in FIGS. 3 and 4, the peripheral wall portion of the cylindrical housing 45 is open at appropriate locations. Further, as shown in FIGS. 3 to 5 and 8, a plurality of belt passage grooves 451 and 452 are formed in the peripheral wall portion of the cylindrical housing 45. As shown in FIGS. Each of the belt passage grooves 451 and 452 is a slit-shaped opening for allowing the partition belt 5 to pass therethrough. These belt passage grooves 451 and 452 have different widths. In this embodiment, the two belt passage grooves 451 and 452 are provided on opposite sides of the central axis of the cylindrical portion 41 . Also, the width dimension of the belt passage groove 451 is relatively small, and the width dimension of the belt passage groove 452 is relatively large. As shown in FIG. 8 , one belt passage groove 451 is positioned on a line segment connecting the center axis of the cylindrical portion 41 and the belt opening 411 .

As shown in FIGS. 4 to 6, a communication port 454 is formed in a bottom plate 453 of the cylindrical housing 45. As shown in FIG. The communication port 454 is a through hole that penetrates the bottom plate 453 in its thickness direction. 5, 6, etc., the inner space of the belt support unit 44 and the inner space of the connecting portion 43 communicate with each other via the communication port 454. As shown in FIG. In this embodiment, a plurality of (four in this embodiment) communication ports 454 are formed in the bottom plate 453 so as to be evenly distributed.

The reel 46 winds and holds the partition belt 5 . The reel 46 is arranged inside the cylindrical housing 45 and is rotatably supported by the cylindrical housing 45 . More specifically, the reel 46 has a winding shaft 461, an upper plate 462 and a lower plate 463, as shown in FIGS. The upper plate 462 and the lower plate 463 are disk-shaped and are connected to the upper and lower ends of the winding shaft 461 . When storing the partition belt 5 , the partition belt 5 is wound around the winding shaft 461 . 3 to 8, the wound partition belt 5 is omitted without being shown. By pulling the belt end 6 located outside the head body 4, the partition belt 5 is let out while the reel 46 rotates.

As shown in FIGS. 5 to 7, an urging means 47 is arranged above the belt support unit 44 . The biasing means 47 is composed of, for example, a spiral spring, and biases the partition belt 5 in the take-up direction. As a result, the partition belt 5 drawn out from the head body 4 is wound around the reel 46 (winding shaft 461) in a non-loaded state.

As shown in FIGS. 4 to 6, the belt support unit 44 (cylindrical housing 45) has its upper portion fixed to the lower portion of the ceiling portion 42 by appropriate means such as screw fastening. 4 and 7, the upper end of the tubular portion 41 is fitted into the lower end of the outer peripheral portion of the ceiling portion 42. As shown in FIG. Furthermore, the upper end of the outer peripheral portion of the connecting portion 43 is fitted onto the lower end of the cylindrical portion 41 . At the same time, the lower portion of the belt support unit 44 (cylindrical housing 45) and the upper portion of the connecting portion 43 are detachably connected by appropriate means such as screw fastening. In this manner, the cylindrical portion 41, the ceiling portion 42, the connecting portion 43 and the belt support unit 44 are assembled together.

The partition belt 5 has a substantially constant width and thickness and extends in a strip shape. As described above, the partition belt 5 can be extended out of the head body 4 through the slit-shaped belt opening 411 provided in the cylindrical portion 41 . Further, in this embodiment, the partition belt 5 wound inside the belt support unit 44 passes through the slit-shaped belt passage groove 451 .

The material of the partition belt 5 is not particularly limited, and various materials can be selected according to the application. It is appropriately set according to the thickness and length of the partition belt 5 and the material of the partition belt 5 . The material of the partition belt 5 is not particularly limited. Examples of the material of the partition belt 5 include a woven fabric sheet made of resin film such as polyethylene film, or synthetic resin fiber such as polyester fiber. Moreover, the partition belt 5 may be subjected to a water-repellent finish or the like, if necessary. The width of the partition belt 5 (dimension in the vertical direction during use) is, for example, about 45 to 50 mm. When the material of the partition belt 5 is a resin film, the partition belt 5 has a thickness of about 0.2 to 0.3 mm and a longitudinal dimension of about 4 to 6 m. When the material of the partition belt 5 is a woven fabric sheet, the partition belt 5 has a thickness of about 0.4 to 0.9 mm and a longitudinal dimension of about 1.5 to 3.5 m.

When the thickness of the partition belt 5 is relatively thin, the head body 4 is assembled so that the partition belt 5 passes through the belt passage groove 451 having a relatively small width dimension. On the other hand, when the partition belt 5 is relatively thick, the head body 4 is assembled so that the partition belt 5 passes through the belt passage groove 452 having a relatively large width dimension.

As shown in FIG. 8, a winding shaft 461 for winding the partition belt 5 has a vertically extending recess 461a and a vertically extending slit 461b connected to the recess 461a. The base end of the partition belt 5 is bag-shaped, and the lock shaft 7 is inserted through the bag-shaped portion positioned in the recess 461a while the base end of the partition belt 5 has passed through the slit 461b. As a result, the base end of the partition belt 5 is engaged with the winding shaft 461 to prevent the partition belt 5 from coming off.

A belt end 6 provided at the tip of the partition belt 5 has a substantially cylindrical shape. A groove having a substantially T-shaped cross section is formed from the lower end to the vicinity of the upper end of the belt end 6 . A belt end receiving portion 412 of the cylindrical portion 41 can be fitted into the groove of the belt end 6 . When the belt partition stand A1 is used, the partition belt 5 is let out and the groove of the belt end 6 is fitted with the belt end receiving portion 412 of the other belt partition stand A1. Thereby, the partition belt 5 can be stretched between the adjacent belt partition stands A1.

As shown in FIG. 9, the column 2 has a cylindrical shape as a whole, and has open top and bottom ends. The pedestal 1 includes a main body 11 and locking members 12 and 13 . A through hole 11a is formed in the center of the main body 11 so as to penetrate vertically. The locking member 12 has a substantially cylindrical shape and is fitted in the through hole 11a. A locking piece 121 extending radially outward is formed at the upper end of the locking member 12 , and the locking piece 121 contacts the upper end of the main body 11 .

The lower end of the post 2 is fitted inside the locking member 12 . In this embodiment, a pair of mounting holes 21 are formed in the lower end portion of the support 2 so as to face each other across the central axis of the support 2 . The locking member 13 has a substantially cylindrical shape and is fitted inside the lower end portion of the column 2 . As a result, the lower end of the post 2 is sandwiched between the locking members 12 and 13 . A nut member 14 is held by the locking member 13 , and a set screw 15 is inserted through the mounting hole 21 from the outside of the locking member 12 and screwed into the nut member 14 . Thereby, the lower end of the post 2, the locking member 12 and the locking member 13 are connected to each other. In the connecting structure between the pedestal 1 and the column 2 shown in FIG. 9, the lower end of the column 2 is inserted into the through hole 11a of the pedestal 1 (main body 11).

The cylindrical portion 431 of the connecting portion 43 is fitted inside the upper end portion of the support 2 . Further, in this embodiment, a pair of mounting holes 22 are formed in the upper end portion of the support 2 so as to face each other with the central axis of the support 2 interposed therebetween. A nut member 432 is held in the cylindrical portion 431 , and a set screw 433 is inserted through the mounting hole 22 from the outside of the column 2 and screwed into the nut member 432 . Thereby, the upper end portion of the column 2 and the cylindrical portion 431 (connecting portion 43) are detachably connected.

Next, the operation of this embodiment will be described.

In the belt partition stand A1 of this embodiment, the head body 4 includes a tubular portion 41, a ceiling portion 42, a connecting portion 43 and a belt support unit 44. The ceiling portion 42 is arranged above the tubular portion 41 and covers the upper end opening of the tubular portion 41 . The connecting portion 43 has a tubular shape and is arranged below the tubular portion 41 . The belt support unit 44 is arranged inside the cylindrical portion 41, and the belt support unit 44 (cylindrical housing 45) is formed with a communication port 454 that communicates from the inner space of the belt support unit 44 to the inner space of the connecting portion 43. For example, when the belt partition stand A1 is used outdoors in rainy weather and the partition belt 5 with water droplets or water is wound around the head body 4, water enters the inside of the belt support unit 44 (inside the head body 4). Also, water may enter the interior of the head body 4 through the belt opening 411 . According to the above configuration, water that has entered the interior of the belt support unit 44 flows down through the communication port 454 into the cylindrical connecting portion 43 and is discharged from the lower end of the connecting portion 43 . Therefore, water is prevented from staying inside the head body 4, and the belt partition stand A1 is also suitable for outdoor use.

The ceiling portion 42 overlaps the entire cylindrical portion 41 when viewed in the vertical direction. The tubular portion 41 as a whole is formed such that its cross-sectional dimension decreases downward. According to such a configuration, when the belt partition stand A1 is used outdoors in rainy weather, water flowing along the outer periphery of the ceiling portion 42 and the tubular portion 41 is prevented from entering the inside of the tubular portion 41 (the head body 4) through the belt opening 411. This makes the belt partition stand A1 more suitable for outdoor use.

The belt support unit 44 is formed with a plurality of slit-shaped belt passage grooves 451 and 452 for allowing the partition belt 5 to pass therethrough. These belt passage grooves 451 and 452 have different widths. The thickness of the partition belt 5 varies depending on the application. However, unlike the present embodiment, if the partition belt 5 has only a single belt passage groove, the width dimension of the belt passage groove needs to correspond to the case where the partition belt 5 is relatively thick. Then, when a partition belt 5 having a relatively thin thickness is used, the gap when the partition belt 5 is passed through the belt passage groove is relatively large, and when winding the partition belt 5, the partition belt 5 may be folded over. In this embodiment, as described above, a plurality of belt passage grooves 451 and 452 having different width dimensions are provided. According to such a configuration, the partition belt 5 can be used through one of the plurality of belt passage grooves 451 and 452 that is suitable for the thickness of the partition belt 5 . Therefore, the belt partition stand A1 of the present embodiment can be used for partition belts 5 with different thicknesses, and can be used by replacing the partition belts 5 with different thicknesses as necessary.

The belt support unit 44 (cylindrical housing 45 ) is integrally attached to the ceiling portion 42 . The upper end of the belt opening 411 of the cylindrical portion 41 is an open end. According to such a configuration, when assembling the head body 4, the belt support unit 44 can be arranged inside the tubular portion 41 while the partition belt 5 fed out from the belt support unit 44 is passed through the open end of the belt opening 411. Thereby, it is possible to easily assemble the head body 4 .

The column 2 has a tubular shape with an upper end and a lower end opened. A through hole 11a is formed in the pedestal 1, and the lower end portion of the column 2 is inserted into the through hole 11a. According to such a configuration, the water that once entered the interior of the belt support unit 44 (inside the head body 4) and then discharged from the lower end of the connecting portion 43 passes through the interior of the support 2 and the base 1 and is efficiently discharged from the lower end of the belt partition stand A1.

10 to 14 show a belt partition stand according to a reference example of the invention. A belt partition stand A2 of this reference example includes a pedestal 1, a support 2 standing from the pedestal 1, a head body 4 connected to the support 2, a partition belt 5, and a belt end 6 provided at the tip of the partition belt 5. The belt partition stand A2 of this reference example differs greatly in the configuration of the head body 4 from that of the belt partition stand A1 of the above-described embodiment, and the base 1 and the struts 2 are also appropriately changed. In the drawings after FIG. 10, the same reference numerals are given to the same or similar elements as in the above-described embodiment, and the description thereof will be omitted as appropriate.

In the belt partition stand A2, the pedestal 1 has a substantially circular plate shape in plan view. Although not shown, the support 2 is detachably connected to the pedestal 1 by fastening with screws, for example. A notch 101 having a constant width is formed in the base 1 . The width dimension of this notch 101 is slightly larger than the outer diameter of the support 2 . When storing a plurality of belt partition stands A2, the storage space can be reduced by fitting the strut 2 into the notch 101 of another belt partition stand A2.

The head body 4 includes a body portion 41A, a top plate 42A, a bottom plate 43A, and a belt support unit 44. A belt opening 411 and a plurality of belt end receiving portions 412 are formed in the body portion 41A in the same manner as the cylindrical portion 41 of the belt partition stand A1 of the above-described embodiment. In the belt partition stand A2, the body portion 41A, the top plate 42A, and the bottom plate 43A are formed in the shape of a closed case in which a belt opening 411 for letting out the partition belt 5 is formed. A connecting screw 431A extending downward is provided in the center of the bottom plate 43A. Although illustration explanation is omitted, the head body 4 (bottom plate 43A) is detachably connected to the upper end portion of the column 2 by screw fastening using a connection screw 431A.

The belt support unit 44 is arranged inside the trunk portion 41A. The configuration of the belt support unit 44 is substantially the same as that of the belt partition stand A1 described above.

In the belt partition stand A2 of this reference example, the belt support unit 44 is formed with a plurality of slit-shaped belt passage grooves 451 and 452 for allowing the partition belt 5 to pass therethrough. These belt passage grooves 451 and 452 have different widths. The thickness of the partition belt 5 varies depending on the application. However, unlike this reference example, if there is only a single belt passage groove, the width dimension of the belt passage groove must correspond to the case where the thickness of the partition belt 5 is relatively thick. Then, when a partition belt 5 having a relatively thin thickness is used, the gap when the partition belt 5 is passed through the belt passage groove is relatively large, and when winding the partition belt 5, the partition belt 5 may be folded over. In this reference example, as described above, the plurality of belt passage grooves 451 and 452 having different width dimensions are provided. According to such a configuration, the partition belt 5 can be used through one of the plurality of belt passage grooves 451 and 452 that is suitable for the thickness of the partition belt 5 . Therefore, the belt partition stand A2 of this reference example can be used for partition belts 5 with different thicknesses, and can be used by replacing the partition belts 5 with different thicknesses as necessary.

Although specific embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications can be made without departing from the spirit of the invention. The specific configuration of each part of the belt partition stand according to the present invention can be changed in various ways.
