The present invention relates generally to a rail barricade including pivotable feet and a plurality of vertical spokes which is attachable to another rail barricade to create a barrier.
Rail barricades are often used in concerts and events to restrict a crowd to a certain area and to prevent the crowd from entering restricted areas. Prior art rail barricades are attached together by a rod and loop attachment to create a barrier of a desired length. Each rail barricade includes a plurality of loops on one side and a vertical rod on the opposing side. To attach the rail barricades, the vertical rod of one of the rail barricades is inserted into the plurality of loops on the other barricade. A plurality of rail barricades are attached in this manner to create a barrier of the desired length.
The frame of the prior art rail barricade is formed of a pair of vertical rails and a pair of horizontal rails which are welded together. A plurality of vertical spokes between the vertical rails are welded at opposing ends to the horizontal rails. The prior art rail barricade also includes a pair of feet perpendicular to the frame of the rail barricade.
A drawback to the rail barricade of the prior art is that each of the rail barricades must be lifted and angled relative to each other to assemble and disassemble the rail barricades, making connection and disconnection of the rail barricades difficult. Finally, as the feet of the prior art rail barricade are perpendicular to the frame, storage and transport of the rail barricade is difficult.
The rail barricade of the present invention includes a bottom rail and a U-shaped body frame having a top rail and a pair of vertical rails. A plurality of vertical spokes are located between the vertical rails.
The bottom rail includes a plurality of bottom holes and the top rail includes a plurality of top holes. In one example, each vertical spoke is inserted into one of the top holes and one of the bottom holes, and the connections of the vertical spokes, the top rail, and the bottom rail are welded. Alternately, the bottom rail includes a plurality of holes each having a curved surface and a flat portion and the top rail includes a plurality of circular top holes. Each vertical spoke includes a lower end with a flattened portion and an upper end with a circular cross-section. When assembled, the lower end of the vertical spoke is positioned in a bottom hole such that the flattened portion of the lower end engages the flat surface of the bottom hole, preventing rotation of the vertical spoke without welding.
The bottom rail further includes an opposing pair of curved ends each having a projection and a curvature equal to the curvature of the vertical rails. The projection of the bottom rail is received in a notch in the vertical rail. The connection is welded, securing the ends of the bottom rail to the vertical rail.
A first foot is pivotally attached to the bottom of one vertical rail, and a second foot is pivotally attached to the bottom of the other vertical rail. The second foot has a length and a height greater than the length and the height of the first foot. The feet are pivotal 90° between an in use position and a storage position. In the in use position, the feet are perpendicular to the bottom rail. In the storage position, the feet are parallel to the bottom rail.
Hooks are attached to one of the vertical rails to attach the rail barricade to a second rail barricade. The second rail barricade is angled approximately 30° from the rail barricade, and the vertical rail of the second rail barricade is positioned in the hooks of the rail barricade. The second rail barricade is then pivoted 30° to align with the rail barricade. When the rail barricades are to be detached, the second rail barricade is again pivoted 30° to allow detaching of the second rail barricade.
These and other features of the present invention will be best understood from the following specification and drawings.
The various features and advantages of the invention will become apparent to those skilled in the art from the following detailed description of the currently preferred embodiment. The drawings that accompany the detailed description can be briefly described as follows:
As shown in
The feet 40 and 44 are pivotal 90° between an in use position shown in
Although only the first foot 40 has been illustrated and described, it is to be understood that second foot 44 includes the same features and is pivotally attached to the vertical rail 30 in the same manner. Additionally, it is to be understood that both the first foot 40 and the second foot 44 can be manually pivoted to other angles besides 90°. Finally, the feet 40 and 44 can be attached to the vertical rail 28 and 30, respectively, by a friction fit, a horizontal slot, without pins, or by other suitable types of attachment.
Returning to
The lower end 114 of each vertical spoke 36 is inserted into one of the bottom holes 100 of the bottom rail 22, and the upper end 116 of each vertical spoke 36 is inserted into one of the top holes 112 of the top rail 26. The connections of each vertical spoke 36 with both the top rail 26 and the bottom rail 22 are then welded to secure the vertical spoke 36 to the top rail 26 and the bottom rail 22.
The bottom rail 22 further includes a projection 106 at each end 32 and 34 of the bottom rail 22. The projection 106 or the bottom rail 22 is received in a hole 112 in the vertical rail 28, shown in
Although the lower end 114 of the vertical spoke 36 and the bottom hole 100 of the bottom rail 22 are illustrated as being flat, it is to be understood that other shapes which prevent rotation of the vertical spokes 36 are possible. Alternatively, the upper end 116 of the vertical spokes 36 and top holes 112 of the top rail 26 can include the flattened portion.
When assembling the rail barricade 20, the circular upper ends 116 of the vertical spokes 36 are inserted into the top holes 112 of the top rail 26. The bottom rail 22 is then assembled on the rail barricade 20 such that the flattened portion 118 of the vertical spokes 36 engage with the flat surface 104 of the bottom holes 100. The projections 106 and 108 of the ends 32 and 34, respectively, of the bottom rail 22 are then inserted into the corresponding notch 110 of the vertical rails 28 and 30, respectively, and the connection is welded. The holes 100 and 112 are formed in the bottom rail 22 and top rail 26, respectively, prior to the assembly of the rail barricade 20, and the plurality of vertical spokes 36 can be easily inserted into the holes 100 and 112 for assembly. The simple assembly of the rail barricade 20 does not require the assembly fixtures required by the prior art rail barricade.
As shown in
The rail barricade 20 is then pivoted to align with the rail barricade 120. When aligned, the second foot 44 of the rail barricade 20 is parallel to the first foot 140 of the rail barricade 120, as shown in
When the rail barricades 20 and 120 are to be detached, the rail barricade 20 is pivoted 30°, returning the rail barricades 20 and 120 to the position of
A plurality of rail barricades 20 are attached to form a barrier of a desired length. As shown in
When the rail barricade 20 is to be transported from one location to another, the feet 40 and 44 are pivoted to be generally parallel to the bottom rail 22. The rail barricade 20 can then be positioned on a transport and moved to a desired location for use or storage. During transport or storage, the rail barricades 20 can be easily stacked as the feet 40 and 44 are generally parallel to the bottom rail 22. Once the rail barricade is to be used, the feet 40 and 44 are pivoted to return to the in use position.
