[0002] A conventional barricade with casters has been disclosed that has single-pipe support parts at the top and bottom of an A-shaped leg body, a caster with level adjustment means at the bottom end of one leg, and anti-slip means at the bottom end of the other leg (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 06-053622 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional barricades with casters, the entire barricade needs to be supported in an tilted position when being moved, which poses the risk of it losing balance and causing the barricade itself to fall over.

[0005] The present invention has been made in response to such problems, and aims to provide a barricade with casters that can be moved safely and easily. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the barricade with casters of the present invention comprises a barricade body, a first leg, a second leg, a link mechanism, a handle, and casters, wherein the first leg and the second leg are configured to support the barricade body, the link mechanism is attached to the handle, the first leg, and the casters, the handle has a lower position and an upper position, and when the handle is in the lower position, the casters are positioned at a height higher than the lower end of the first leg, and when the handle is in the upper position, the casters are positioned below the lower end of the first leg and are configured to support the first leg.

[0007] The caster-equipped barricade of the present invention can block an aisle with the barricade body. When the handle is positioned in the lower position, the casters can be positioned via the link mechanism at a height equal to or higher than the lower end of the first leg, allowing the first leg to be placed in an installed state. When the handle is positioned in the upper position, the casters support the first leg via the link mechanism, allowing safe and easy movement. The natural movement of lifting the handle allows movement on the casters, making the barricade easy to handle.

[0008] In the caster-equipped barricade of the present invention, it is preferable that the barricade body is attached to the second leg so that it can rotate along a horizontal plane around the second leg when the second leg is placed on a horizontal plane. In this case, the barricade body can be rotated along a horizontal plane around the second leg to change its installation position.

[0009] In the caster-equipped barricade of the present invention, it is preferable that the barricade body is attached to the first leg and the second leg so as to be rotatable about a horizontal axis when the first leg and the second leg are placed on a horizontal surface. In this case, since the barricade body can be rotated up and down relative to the first leg and the second leg, the first leg and the second leg can be installed at positions at different heights.

[0010] In the barricade with casters according to the present invention, it is preferable that the barricade body is configured to be extendable and contractible in the length direction between the first leg portion and the second leg portion. In this case, the barricade body can be extended or retracted to open or close the blocked passage or change the length of the blockage.

[0011] In the caster-equipped barricade of the present invention, the link mechanism has a first link, a second link, and a support part, the handle is attached to the upper end of the first link, the first link is attached to the first leg so as to be slidable vertically when the first leg is placed on a horizontal surface, the middle part of the second link is attached to the first leg so as to be rotatable around a horizontal first axis when the first leg is placed on a horizontal surface, the upper end of the second link is attached to the lower end of the first link so as to be rotatable around a second axis parallel to the first axis, and the lower end is attached to the support part so as to be rotatable around a third axis parallel to the first axis and slidable vertically relative to the third axis, and it is preferable that the support part is attached to the first leg so as to be slidable up and down, and the casters are swivel casters attached to the support part.

[0012] In this case, when the handle is positioned in the lower position, the caster is positioned at a height equal to or higher than the lower end of the first leg. When the handle is positioned from the lower position to the upper position, the first link slides upward relative to the first leg, the second link rotates about the first axis, the support part slides downward relative to the first leg, and the caster is positioned below the lower end of the first leg to support the first leg and facilitate movement. [Effects of the Invention]

[0013] According to the present invention, a barricade with casters that can be moved safely and easily can be provided. [Brief explanation of the drawings]

[Figure 5] FIG. 5 is a plan view showing the wheeled barricade of FIG. 4. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show a barricade with casters according to an embodiment of the present invention. As shown in FIG. 1, the barricade with casters has a barricade body 1, a first leg 2, a second leg 3, a link mechanism 4, a handle 5, and casters 6.

[0016] The barricade body 1 consists of two pipes 11 and 12. As shown in Figure 2, the first leg 2 has two legs 21, two connecting pipes 22 and 23, and a connecting member 24. The two legs 21 are the same length and are arranged on two equal-length sides of an acute isosceles triangle. The two connecting pipes 22 and 23 are different lengths and parallel, with both ends connected to the top and bottom of each leg 21 at the same height. The connecting member 24 is connected to each leg 21 at the same height, midway between the two connecting pipes 22 and 23.

[0017] The second leg 3 has the same shape as the first leg 2, and further has two legs 31. The two legs 31 extend in directions rotated 90 degrees from each leg 21 in a plan view. The first leg 2 and the second leg 3 have a tubular member 25 around each connecting pipe 22, 23. The tubular member 25 is rotatably mounted coaxially with the connecting pipes 22, 23. A clamp member 26 is fixed to the outer circumferential surface of the tubular member 25. The central axis of the clamp member 26 is parallel to or twisted with the central axis of the tubular member 25, and the clamp member 26 is rotatable about an axis extending in the diameter direction of the tubular member 25. The clamp member 26 can secure the tubular members 11, 12 with bolts and nuts. Note that a cam lock or other fixing member may be used instead of the clamp member to secure the tubular members 11, 12.

[0018] The first leg 2 and the second leg 3 support the barricade body 1 by fixing the ends of the pipes 11 and 12 with clamps 26. Each clamp 26 is made of a swivel clamp. This allows the barricade body 1 to rotate along the horizontal plane around the first leg 2 or the second leg 3 when the first leg 2 and the second leg 3 are placed on a horizontal surface. Furthermore, when the first leg 2 and the second leg 3 are placed on a horizontal surface, the barricade body 1 can rotate around a horizontal axis.

[0019] The link mechanism 4 has a first link 41, a second link 42, and a support portion 43. The handle 5 is attached integrally to the upper end of the first link 41. The first link 41 is bent in a crank shape. The connecting member 24 has a ring 24a in the center, which has a through hole in the vertical direction. The first link 41 is inserted into the ring 24a at an upper position below the handle 5, and is attached to the first leg 2 so as to be slidable in the vertical direction when the first leg 2 is placed on a horizontal surface. As a result, the handle 5 has a lower position and an upper position.

[0020] The second link 42 has an intermediate portion attached to the first leg 2 so as to be rotatable about a horizontal first axis 42a when the first leg 2 and the second leg 3 are placed on a horizontal plane. The second link 42 has an upper end attached to the lower end of the first link 41 so as to be rotatable about a second axis 42b parallel to the first axis 42a. The second link 42 has a lower end attached to the support portion 43 so as to be rotatable about a third axis 42c parallel to the first axis 42a and slidable in a direction perpendicular to the third axis 42c.

[0021] A rail member 27 that extends vertically when the first leg 2 is placed on a horizontal surface is fixed to the connecting pipe 23. One end of the support portion 43 is attached to the rail member 27 so that it can slide up and down when the first leg 2 is placed on a horizontal surface. The caster 6 is a swivel caster and is attached to the support portion 43. When the handle 5 is in the down position, the caster 6 is positioned at a height equal to or higher than the lower end of the first leg 2. When the handle 5 is in the up position, the caster 6 is positioned below the lower end of the first leg 2 and can support the first leg 2.

[0022] The caster-equipped barricade of the present invention can block an aisle with the barricade body 1. When the handle 5 is normally positioned in the down position, the caster 6 is positioned above the height of the lower end of the first leg 2, allowing the first leg 2 to be stably installed. When the handle 5 is lifted with one hand to move it from the down position to the up position, the first link 41 slides upward relative to the first leg 2, the second link 42 rotates about the first axis 42a, and the support part 43 slides downward relative to the first leg 2, so that the caster 6 is positioned below the lower end of the first leg 2 to support the first leg 2, allowing safe and easy movement. The caster 6 can be moved by the natural movement of lifting the handle 5, making the barricade easy to handle.

[0023] Furthermore, the barricade with casters can be positioned by rotating the barricade body 1 along a horizontal plane around the second leg 3. In addition, the caster-equipped barricade allows the barricade body 1 to be rotated up and down relative to the first leg 2 and the second leg 3, so that the first leg 2 and the second leg 3 can be installed at different heights, as shown in Figure 3.

[0024] 4 and 5 show a wheeled barricade according to another embodiment of the present invention. 4 and 5, the same parts as those in the barricade with casters shown in FIGS. 1 to 3 are denoted by the same reference numerals, and duplicated explanations will be omitted. As shown in Figures 4 and 5, the barricade with casters has a barricade body 1, an extendable barricade body 1a, a first leg 2, a second leg 3, a third leg 3a, a link mechanism 4, a handle 5, casters 6, and a slider member 7.

[0025] The barricade body 1 and the retractable barricade body 1a each consist of two pipes 11, 12. The first leg 2, the second leg 3, and the third leg 3a are configured in the same manner as the first leg 2 of the barricade with casters in accordance with the embodiment of the present invention. The second leg 3 and the third leg 3a support the barricade body 1 with clamp members 26a. The clamp members 26a are fixed to the second leg 3 and the third leg 3a, respectively. The link mechanism 4, the handle 5, and the casters 6 are attached to the first leg 2 in the same manner as the barricade with casters in accordance with the embodiment of the present invention.

[0026] The slider member 7 has an upper slider 71, a lower slider 72, a connecting member 73, and two clamp members 26a. The upper slider 71 and the lower slider 72 partially cover the barricade body 1 so that they can slide relative to the barricade body 1. The upper slider 71 and the lower slider 72 have wheels where they contact the barricade body 1 to facilitate sliding. The connecting member 73 connects the upper slider 71 and the lower slider 72. Each clamp member 26a is fixed to the side of the upper slider 71 and the lower slider 72 on the same side. Each clamp member 26a fixes and supports one end of the retractable barricade body 1a.

[0027] The first leg 2 supports the other end of the retractable barricade body 1a by fixing it with a clamp 26a. This allows the barricade body 1 and the retractable barricade body 1a to be retractable in the length direction between the first leg 2 and the second leg 3. In another embodiment of the barricade with casters of the present invention, the barricade body 1 and the extendable barricade body 1a can be extended and retracted to open and close the blocked passage and change the length of the blocked passage.
