Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the case of the above-described gate-type barrier, for example, the visibility is poor, especially from large vehicles with a high vehicle height, and there is a possibility that a vehicle may try to enter the parking lot by mistake even in a situation where entry is restricted. As a result, the barrier malfunctions and becomes unusable, and vehicles get stuck at the entrance and exit of the parking lot. If the parking lot is operating during business hours, it may cause congestion in the vicinity of the parking lot.

[0006] Therefore, in view of such a situation, the present invention provides an access control device with good visibility and capable of enhancing the effect of restricting vehicle entry.

Means for Solving the Problems

[0007] An entry restriction device according to one aspect of the present invention is an entry restriction device installed on a passageway at the entrance to a target area into which vehicles can enter, for restricting the entry of the vehicle into the target area, and comprises a vertical column extending upward from the passageway and a horizontal column extending in the width direction of the passageway above the passageway, a sheet-like member suspended downward from the horizontal column and positioned in the space between the passageway and the horizontal column, and a weight member provided at the lower part of the sheet-like member.

[0008] In the above-described entry restriction device, both edges of the sheet-like member in the direction of the passage width may be positioned away from the vertical column.

[0009] In the above-described entry restriction device, the sheet-like member may have, at least in its lower portion, a plurality of sheet pieces separated in the passage width direction and arranged in the passage width direction.

[0010] In the above-described entry restriction device, the sheet-like member has slits formed between the sheet pieces, extending upward from the bottom, and separating the sheet-like member into multiple sections. These slits may be formed from the bottom up to an intermediate height position within a range of more than half of the total height of the sheet-like member.

[0011] In the above-described entry restriction device, the sheet-like member may have a continuous region above the plurality of sheet pieces, which spans the plurality of sheet pieces in the direction of the passage width.

[0012] In the above-described entry restriction device, fixing members may be provided between adjacent sheet pieces in the passage width direction to secure the sheet pieces together.

[0013] In the above-described entry restriction device, the fixing member may fix the sheet pieces together such that they separate when the vehicle comes into contact with them.

[0014] In the above-described entry restriction device, a housing for accommodating the weight member is provided at the lower part of the sheet-like member, and the housing is provided separately in the direction of the passage width for each sheet piece, and the fixing member may fix the housings together.

[0015] The above-mentioned entry restriction device may further include a drum mounted on the horizontal column that rotates about an axis extending in the direction of the passage width, enabling the winding and unwinding of the sheet-like member.

[0016] The above-mentioned entry restriction device may further include a drive unit that is mounted on the vertical column and connected to the drum, and that rotates the drum.

[0017] In the above-described entry restriction device, the horizontal column is a drum cover having a downward opening that houses the drum inside and on which the sheet-like member is positioned. A flexible housing is provided at the lower part of the sheet-like member that houses the weight member. The dimension of the horizontal column in the thickness direction, which intersects the width direction of the passage and is aligned with the direction of travel of the vehicle, may be larger for the housing than for the opening.

[0018] In the above-described entry restriction device, when the housing approaches the opening, the opening may be covered by the housing.

[0019] In the above entry restriction device, the housing may have a thickening material arranged on the outer circumference of the weight member to increase the dimension of the weight member in the thickness direction of the horizontal column.

[0020] In the above-described entry restriction device, a protruding member may be provided on a portion of the surface of the sheet-like member in the passage width direction, which protrudes from the surface of the sheet-like member and extends in the height direction. [Effects of the Invention]

[0021] According to the above-described embodiment of the entry restriction device, visibility is improved and the effectiveness of restricting vehicle entry is enhanced.

Modes for Carrying Out the Invention

[0023] Embodiments of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 5 are examples of embodiments of the present invention. The entry restriction device 100 of this embodiment is a device installed on a passage R at the entrance and exit of an entry target area and restricts vehicle entry into the entry target area by blocking or opening the passage R. The entry target area is not particularly limited, but may include, for example, a parking lot, a predetermined area on a road where vehicle entry must be temporarily restricted due to construction, or an underpass during flooding.

[0024] (Overall structure) As shown in Figure 1, the entry restriction device 100 comprises a horizontal column 2 supported by a vertical column 1 provided in the passageway R, a sheet-like member 3 suspended from the horizontal column 2, a weight member 4 provided at the bottom of the sheet-like member 3, a drum 5 for winding and unwinding the sheet-like member 3, and a drive unit 6 for driving the drum 5.

[0025] (Horizontal pillar) The horizontal column 2 is erected in the passageway R and supported by the vertical column 1, which extends upward in the height direction from the passageway R, and is positioned above the passageway R. A pair of vertical columns 1 are provided spaced apart in the passageway width direction. The horizontal column 2 also extends in the passageway width direction. In a front view from the front side in the horizontal column thickness direction, which intersects the passageway width direction and is aligned with the direction of vehicle travel, the pair of vertical columns 1 and the horizontal column 2 form a gate shape. Note that the front side here refers to the front side of the paper in Figure 1. Also, as shown in Figure 2, the horizontal column 2 is attached to the vertical column 1 on the front side in the horizontal column thickness direction.

[0026] As shown in Figure 3, the horizontal column 2 has a downward opening 2a. Also, as shown by the dashed line in Figure 3, the horizontal column 2 has an inspection cover 20 at its lower part so that the opening area of ​​the opening 2a can be enlarged. The inspection cover 20 is designed to rotate around an axis O2 extending in the direction of the passage width by a rotating member such as a hinge (not shown). When the inspection cover 20 rotates, the edge 20a on the front side in the direction of travel is moved downward, enlarges the opening area of ​​the opening 2a of the horizontal column 2, and makes it possible to inspect the members installed inside the horizontal column 2.

[0027] (drum) The drum 5 is housed within the horizontal column 2. Therefore, in this embodiment, the horizontal column 2 serves as a drum cover. The drum 5 is rotatably mounted relative to the horizontal column 2 about an axis O extending in the direction of the passage width. In this embodiment, a pair of drums 5 are spaced apart at the center of the passage width direction (see Figure 1).

[0028] (Sheet-like material) Returning to Figure 1, the sheet-like member 3 is suspended downward from the horizontal column 2, with its upper part supported by the drum 5. A pair of sheet-like members 3 are provided at spaced intervals at the center of the horizontal column 2 in the direction of the passage width, corresponding to each drum 5 arranged in the direction of the passage width. The edges of the sheet-like member 3 in the direction of the passage width are also positioned away from the vertical column 1. Since the pair of sheet-like members 3 have the same configuration, we will describe one of the sheet-like members 3 in detail below.

[0029] The sheet-like member 3 is positioned in the space between the passageway R and the horizontal column 2. The sheet-like member 3 is made of a flexible material such as a cloth sheet or a resin sheet. The sheet-like member 3 is wound upward and unwound downward by the rotation of the drum 5. As will be described in more detail later, as shown in Figure 4, when the sheet-like member 3 is wound onto the drum 5, the sheet-like member 3 is housed within the horizontal column 2.

[0030] As shown in Figure 5, the sheet-like member 3 is formed by separating into multiple (three in this embodiment) sections in the passage width direction at its lower part. Specifically, the sheet-like member 3 has slits 3a that extend upward from the lower part and separate the sheet-like member 3 into multiple sections. The slits 3a are formed from the lower part (lower end) of the sheet-like member 3 to an intermediate height position in the sheet-like member 3. It is preferable that the slits 3a are formed from the lower part of the sheet-like member 3 to a range of more than half of the total length in the height direction of the sheet-like member 3 (see Figure 1). With this configuration, the sheet-like member 3 has multiple sheet pieces 30 arranged in the passage width direction with the slits 3a in between. Furthermore, the sheet-like member 3 has a continuous region 31 above the multiple sheet pieces 30 that is arranged across the multiple sheet pieces 30 in the passage width direction. Therefore, the multiple sheet pieces 30 are separated from each other in the passage width direction at the lower part and are separated from each other in the passage width direction at the upper part. It is integrated into it.

[0031] Furthermore, a protruding member 8 is provided on a part of the surface of the sheet-like member 3 (in this embodiment, the front surface in the thickness direction of the horizontal column). The protruding member 8 is strip-shaped, protruding from the surface of the sheet-like member 3 towards the front in the thickness direction of the horizontal column and extending in the height direction. In this embodiment, multiple protruding members 8 are provided at intervals in the width direction of the passage. More specifically, the protruding members 8 are arranged alternately with the slits 3a at intervals from each other in the width direction of the passage. For example, blocks made of resin material can be used for the protruding members 8. Note that the protruding members 8 may also be provided on the back surface in the thickness direction of the horizontal column. Also, the protruding members 8 are not limited to being strip-shaped, but may be a combination of multiple block-shaped members arranged at intervals in the height direction. As shown in Figure 6, when the sheet-like member 3 is wound up by the drum 5, the protruding members 8 are positioned between the surfaces of the sheet-like member 3.

[0032] Furthermore, a housing 32 is provided at the lower part of the sheet-like member 3. The housing 32 is positioned above the road surface of the passage R when the sheet-like member 3 is fully unrolled (see Figure 1). A housing 32 is also provided for each sheet section 30. Therefore, multiple housings 32 are provided, separated in the passage width direction. Returning to Figures 3 and 4, each housing 32 is cylindrical in shape extending in the passage width direction and is provided integrally with the sheet-like member 3. The housing 32 has an outer cylindrical body 33, an inner cylindrical body 34, and a thickening material 35 provided between the outer cylindrical body 33 and the inner cylindrical body 34.

[0033] A weight member 4, described later, is housed inside the inner cylinder 34. Although detailed illustrations are omitted, both ends of the inner cylinder 34 in the passage width direction are fixed by sealing devices such as buttons, stitching, or eyelets, but it can also be closed and opened using sealing devices such as zippers (linear fasteners), hook-and-loop fasteners, or screws (jigs). The thickening material 35 is arranged on the outer circumference of the weight member 4 or the inner cylinder 34. The thickening material 35 is a member that increases the dimension in the thickness direction of the horizontal column, and is a cushioning material made of a flexible resin material such as urethane foam. The outer cylinder 33 and the inner cylinder 34 are formed from the same material as the sheet-like member 3, that is, a flexible material such as a cloth sheet or a resin sheet, and are provided integrally with the sheet-like member 3. Therefore, the housing 32 as a whole is flexible.

[0034] As shown in Figure 4, the dimension W2 in the thickness direction of the horizontal column in the housing 32 is larger than the dimension W1 in the thickness direction of the horizontal column in the opening 2a of the horizontal column 2. Therefore, when the drum 5 winds up the sheet-like member 3, the housing 32 approaches the horizontal column 2, and the opening 2a of the horizontal column 2 is covered by the housing 32. Furthermore, as the drum 5 winds up the sheet-like member 3, the housing 32 is pressed against the edge of the opening 2a of the horizontal column 2, causing the housing 32 to deform, and in a cross section perpendicular to the axis O of the drum 5, the housing 32 closes the opening 2a of the horizontal column 2.

[0035] As shown in Figure 5, a fixing member 7 is provided at the lower part of the storage body 32, positioned between adjacent storage bodies 32 in the passage width direction, to secure these storage bodies 32 together. In this embodiment, the fixing member 7 is a hook-and-loop fastener provided on the inner surface of the outer cylindrical body 33, but it is not limited to this, and may be a member that secures the storage bodies 32 together, for example, by a button, zipper (linear fastener), or screw (jig). The sheet pieces 30 adjacent to each other in the passage width direction are then detachably fixed together by the fixing member 7.

[0036] (Weight component) The weight members 4 are individually inserted into the inner cylindrical bodies 34 of each housing 32 so as to be removable from the direction of the passage width. Therefore, the weight members 4 are provided at the bottom of the sheet-like member 3 and have the function of positioning the bottom of the sheet-like member 3 in a predetermined position by gravity. The material of the weight member 4 is not particularly limited, but it is preferable that it has a higher density than the sheet-like member 3 and has enough weight to prevent the bottom of the sheet-like member 3 from moving due to rain and wind, etc., but to be movable when a vehicle comes into contact with it. Specifically, the weight member 4 may be, for example, a container made of a flexible material such as a cloth sheet or a resin sheet containing sand or water, or a combination of several short cylindrical metals arranged at intervals in the direction of the passage width to form a cylindrical flexible material.

[0037] (Drive unit) Returning to Figure 1, one drive unit 6 is provided on each of the pair of vertical columns 1. Each drive unit 6 rotates a pair of drums 5 that are arranged in the width direction of the passageway. As shown in Figure 7, each drive unit 6 has a cylindrical case 61 that extends in the height direction, a drive source 62 housed in the case 61, a control device 63 that controls the drive source 62, and a transmission mechanism 64 that connects the drive source 62 and the drums 5.

[0038] Case 61 is attached to the vertical column 1 via bracket 61a on the front side in the thickness direction of the horizontal column (see Figure 1). The upper part of case 61 is connected from below to the end of the horizontal column 2 in the width direction of the passage (see Figure 1). The drive source 62 is, for example, an electric motor. The control device 63 controls the operation of the drive source 62. The transmission mechanism 64 has a rotating shaft 64a that is rotated by a drive source 62. The rotating shaft 64a is rotatable about an axis O6 that extends in the height direction. A portion of the rotating shaft 64a protrudes downward from the drive source 62. A handle 66 is detachably attached to the portion of the rotating shaft 64a that protrudes from the drive source 62. The handle 66 is provided for manually rotating the drum 5 when the operation of the drive source 62 is stopped. Furthermore, as shown in Figures 8 and 9, the transmission mechanism 64 also has a coupling 67 that connects the rotating shaft 64a and the drum 5 when the case 61 is connected to the end of the passage width direction in the horizontal column 2. The coupling 67 has a drum-side member 67a that is connected to the drum 5 and protrudes downward from the horizontal column 2, and a drive source-side member 67b that is connected to the rotating shaft 64a and is located inside the case 61. As shown in Figure 8(a), the horizontal column 2 and the case 61 are brought close together in the height direction, and as shown in Figure 8(b), the horizontal column 2 and the case 61 are connected, thereby connecting the drum-side member 67a and the drive source-side member 67b. At this time, it is preferable that the drum-side member 67a and the drive source-side member 67b are connected with a small gap S in the height direction so that thermal deformation of the rotating shaft 64a, etc., can be absorbed. As shown in Figure 9, the drum-side member 67a has a circular base 68 when viewed from below, and multiple (three) teeth 69 that protrude downward from the base 68 and are spaced apart in the circumferential direction. Although not shown in the figure, the drive source-side member 67b has a similar structure to the drum-side member 67a.

[0039] In the control device 63, the upward stopping position and downward stopping position of the sheet-like member 3 are set in advance by program, and the amount of rotation of the drum 5 is detected using the counter 63a. When it is determined that the sheet-like member 3 has reached the upward stopping position or the downward stopping position, the drive source 62 is controlled to stop. Here, the upward stopping position refers to the position where the opening 2a of the horizontal column 2 and the housing 32 at the lower end of the sheet-like member 3 are close together, as described above. Note that "close" includes cases where the housing 32 does not completely contact the lower part of the opening 2a of the horizontal column 2 (the exit side of the sheet-like member 3), but preferably it refers to cases where it is in contact with the exit side of the opening 2a.

[0040] The control method for the drive source 62 by the control device 63 is not particularly limited, and the drive source 62 may be stopped by detecting an inverter trip of the drive source 62. Specifically, when the drive source 62 is operated to rotate the drum 5 and the sheet-like member 3 is wound onto the drum 5 as shown in Figure 4, the housing 32 is pressed against the horizontal column 2. This causes the drive source 62 to become overloaded, and the control device 63 detects a trip in the inverter (not shown) of the drive source 62. The control device 63 then stops the operation of the drive source 62 in response to the detection of the inverter trip. For example, an inverter trip is detected when the sheet-like member 3 rises about 10 cm further after the housing 32 has contacted the horizontal column 2.

[0041] (Effects and Benefits) The entry restriction device 100 of this embodiment described above employs a simple structure in which a sheet-like member 3 is suspended from a horizontal column 2, resulting in excellent visibility, ease of installation, and reduced manufacturing costs. Furthermore, since a weight member 4 is provided at the bottom of the sheet-like member 3, it is possible to prevent the sheet-like member 3 from bending due to rain, wind, etc., and if a vehicle attempts to enter the entry area and comes into contact with the sheet-like member 3, the lower part of the sheet-like member 3 moves, minimizing damage to the vehicle.

[0042] Furthermore, both edges of the sheet-like member 3 in the direction of the passage width are positioned away from the vertical column 1 and are not fixed to the vertical column 1. Therefore, when a vehicle comes into contact with the sheet-like member 3, the sheet-like member 3 is more likely to flex, further reducing damage to the vehicle upon contact.

[0043] Furthermore, the sheet-like member 3 has multiple sheet pieces 30. Therefore, when a vehicle comes into contact with the sheet-like member 3, the sheet pieces 30 can move apart from each other in the direction of the passage width with the slit 3a in between, thereby reducing damage to the vehicle when it comes into contact with the member.

[0044] Furthermore, the sheet pieces 30 are integrated at the top by a continuous region 31, making it easier to attach them to the drum 5 compared to when the sheet pieces 30 are completely separate from each other, and reducing the effort required when installing the entry restriction device 100.

[0045] Furthermore, by a simple method such as forming a slit 3a in a single sheet-like member 3 up to a certain height, multiple sheet pieces 30 can be formed on the sheet-like member 3, thereby reducing manufacturing costs.

[0046] Furthermore, by forming the slit 3a from the bottom of the sheet-like member 3 to a range of more than half of the total length of the sheet-like member 3 in the height direction, the height dimension of the sheet piece 30 can be secured, and when the vehicle comes into contact with it, the sheet piece 30 can move more easily, further reducing damage to the vehicle.

[0047] Furthermore, fixing members 7 are provided between the sheet pieces 30, so that the sheet pieces 30 are normally integrated. This prevents the sheet pieces 30 from moving freely in different directions due to the effects of rain and wind, etc., while if a vehicle comes into contact with the sheet-like member 3, the fixing of the sheet pieces 30 by the fixing members 7 is released, allowing the sheet pieces 30 to move freely in different directions, thereby reducing damage to the vehicle. In particular, in this embodiment, the fixing members 7 fix the sheet pieces 30 together by fixing adjacent storage bodies 32 together. Therefore, the sheet pieces 30 can be fixed together at the bottom by the fixing members 7, further enhancing the effect of suppressing the free movement of the individual sheet pieces 30 under normal conditions.

[0048] Furthermore, since the drum 5 can be used to wind up and unwind the sheet-like member 3, if it is not necessary to block the passage R, the sheet-like member 3 can be wound onto the drum 5 and moved upward, or the lower part of the sheet-like member 3 can be positioned at a desired height.

[0049] Furthermore, in this embodiment, since the horizontal column 2 serves as a drum cover, the sheet-like member 3 can be housed inside the horizontal column 2 when it is wound onto the drum 5. Therefore, the possibility of the sheet-like member 3 being exposed to rain and wind when the entry restriction device 100 is not in use is reduced, which helps to prevent deterioration of the sheet-like member 3.

[0050] Furthermore, since the dimension of the housing 32 in the thickness direction of the horizontal column is larger than the opening 2a of the horizontal column 2, and the housing 32 is flexible, when the housing 32 approaches and comes into contact with the opening 2a, the opening 2a is covered by the housing 32 and the opening 2a can be closed. Thus, the inside of the horizontal column 2 can be closed by the housing 32, further reducing the possibility that the drum 5 and the sheet-like member 3 wound on the drum 5 will be exposed to rain and wind. Also, in this embodiment, a cushioning material as a thickening material 35 is provided on the outer circumference of the weight member 4, so that the thickening material 35 is opposed to the edge of the opening 2a of the horizontal column 2 and pressed against the opening 2a together with the weight member 4. Thus, it is possible to close the opening 2a without increasing the volume of the weight member 4, the weight of the weight member 4 is reduced, the stress (tension) generated in the sheet-like member 3 by the weight member 4 is reduced, and the deterioration of the sheet-like member 3 is reduced.

[0051] Furthermore, by providing the protruding member 8 on the surface of the sheet-like member 3, surface contact between the surfaces of the sheet-like members 3 can be avoided when the sheet-like members 3 are wound onto the drum 5, thereby preventing dirt from adhering to the surface of the sheet-like members 3 or the surfaces of the sheet-like members 3 from adhering to each other during repeated winding and unwinding of the sheet-like members 3.

[0052] Although embodiments of the present invention have been described in detail above with reference to the drawings, the configurations and combinations thereof in the above embodiments are merely examples, and additions, omissions, substitutions, and other modifications are possible without departing from the spirit of the present invention. Furthermore, the present invention is not limited by the embodiments, but only by the claims.

[0053] For example, the sheet-like member 3 does not necessarily have to have a slit 3a. That is, the sheet-like member 3 does not necessarily have to have a sheet piece portion 30. Alternatively, the slit 3a may be formed over the entire height of the sheet-like member 3. That is, the sheet-like member 3 may not have a continuous region 31 and may consist only of sheet pieces 30.

[0054] Furthermore, the fixing member 7 is not limited to fixing the storage sections 32 together, but may also be provided across the sheet pieces 30 to fix adjacent sheet pieces 30 in the aisle width direction.

[0055] Furthermore, the containment body 32 is not necessarily provided, and the weight member 4 may be directly attached to the sheet-like member 3.

[0056] Furthermore, the drum 5 does not necessarily have to be housed within the horizontal column 2; the drum 5 may be exposed from the horizontal column 2. Also, the drive unit 6 may be provided on the horizontal column 2, for example, instead of the vertical column 1. [Industrial applicability]
