Abstract

The present invention provides a two-piece temporary fence support. The support member has: a base having a pair of apertures therethrough disposed proximate a midpoint of the base; a plate having a pair of apertures disposed therethrough, the pair of apertures being sized to mate with the base; a pair of stakes extending vertically from the plate, each stake allowing a fence panel to be mounted thereon; and a pair of fasteners disposed through the apertures of the base and the plate to secure the plate to the base.

Description

Two-piece temporary fence support

Technical Field

The following relates generally to physical barriers and more particularly to a two-piece temporary fence support.

Background

For example, construction sites, festivals, events, etc., it is often necessary to erect the barrier quickly or temporarily. These barriers may be used to prevent ingress and egress to a particular location, or to guide the flow of people. An example of a conventional barrier is a temporary fence. Conventional temporary fencing typically includes a series of posts interconnected by fence panels (panels). Traditionally, temporary enclosures are freestanding, or otherwise self-supporting, that are not permanently attached to the ground.

Conventional temporary fence panels are supported by a support having a transverse base for placement along the ground and a vertical member incorporating one or more stakes that support the panel. The vertical member most commonly has two stakes that each support an end of one panel and that together support adjacent ends of two panels. The support is most commonly made of metal, such as steel. In these cases, the vertical members are typically welded to the base to maximize strength and rigidity.

Due to the nature of the use of temporary fencing, fence panels are often moved frequently, whether intentionally or not. Inadvertent contact with the panel can result in shear forces being applied to the vertical member. Eventually, the vertical member will become bent or broken.

The industry has only accepted this problem of continuous fracture through normal wear. A common method of repairing the base is to grind off the damaged part and then weld on a new vertical part. If this operation is done by the fence supplier, the cost of grinding and welding new parts is about $ 7-10 (as of the date written), plus the time, effort, skill and expense required.

It is therefore an object of the present invention to provide a fence support in which the above disadvantages are eliminated or mitigated and which contributes to achieving the desired attributes.

Other definitions for terms may be set forth herein; as will be understood from reading this specification, these other definitions apply to previous and subsequent examples of those terms.

Referring first to fig. 1, a fence support (100) according to the present invention is shown. The rail support includes a first part that is a base (102) and a second part that is a vertical member (104). Each of the base (102) and the vertical member (104) is preferably made of metal and preferably steel. The base (102) and vertical member (104) may additionally be coated with enamel to reduce wear. The base (102) shown is a longitudinally extending, generally flat metal plate; that is, its length is typically much longer than its width. The base (102) is also substantially symmetrical about its midpoint (106) in the longitudinal and transverse axes so that it can be rotated 180 ° without interfering with use. However, these physical characteristics can be altered so long as the base is sufficient to support the fence panel mounted thereon.

From the midpoint (106), the first aperture (108) is disposed a small distance from the midpoint, preferably midway along the lateral axis of the base (102). In alternative embodiments, a single aperture may be provided along the base (102), which may preferably, but not necessarily, be located at or a small distance from the midpoint of the base. The aperture (108) may be circular, but is preferably non-circular in shape and is designed to cooperate with a non-circular portion of the fastener to prevent relative movement between the fastener and the aperture (108) for reasons that will be described later. The non-circular shape shown in the figures is a square, but may be other suitable polygonal shapes such as a hexagon, octagon, etc.

The base (102) is then generally solid. Optionally, the elliptical aperture (110) may be formed proximate an end of the seat (102), also preferably midway along a transverse axis of the seat (102). The oval aperture (110) allows the base to be secured to a heavy or non-movable structure (not shown), such as a concrete weight or the ground. For example, fixation in this manner may be achieved by fasteners (not shown), such as screws, nails, stakes, or bolts.

The vertical member (104) comprises a plate (112), and two vertical posts (114, 116) stand from the plate (112). The plate (112) shown is generally square and contains two apertures (118) that match the apertures of the base; that is, they are equally spaced from the aperture (108) of the base (102). These apertures (118) may be circular or any other shape that allows a fastener to pass therethrough. As with the base (102), there may be only one or more than two apertures (118). Two or more such apertures provide benefits such as preventing rotation between the plate (112) and the base (102).

Further, the plate (112) may contain only a single stud (114, 116) rising from the plate. This may be beneficial for using the terminal post at the end of the installation of the modular fence panel. In this case, it is preferable to use the post (116) instead of the post (114) to increase stability. In addition, it is possible to provide more than two studs (114, 116) to facilitate more complex structures.

The plate (112) may then be secured to the base (102) by using fasteners. The fastener shown contains two sets of bolts (120), washers (122), and nuts (124). In this way, the fastener not only replaces the welding of prior art solutions, but also allows easier replacement of broken or damaged vertical components (104). The use of two fasteners also prevents relative rotation of the plate (112) and the base (102).

As previously mentioned, the bolt (120) preferably includes a non-circular portion along its length that is selected to mate with the aperture (108) to prevent relative rotation therebetween. This allows a person to tighten the nut (124) without having to manually hold/secure the bolt on the bottom of the base (102), as the base (102) performs such a function on the nut.

Figure 2 shows the support after assembly.

Referring now to fig. 3 and 4, the vertical posts (114, 116) may take any cross-sectional shape that allows for support of the corresponding fence panels (300, 302). Without limiting the invention, such panels may have square vertical stakes (304) with hollow interiors. In this case, the vertical post (116) preferably also has a square cross-section and fits tightly within the hollow interior to prevent relative rotation between the vertical post (116) and the panel. The panels are typically mounted over the piles and are held in place by a combination of gravity, mass and friction fit.

The cross-sectional shape of the vertical post (114) may also be square. However, because such a shape would allow adjacent fence panels to be provided only in a collinear or vertical arrangement, the vertical posts (114) are preferably circular such that one panel supported by the vertical post (116) is held securely in place while an adjacent panel supported by the vertical post (114) is rotatable to a desired angle.

While both vertical posts (114, 116) may be circular in cross-section, this is not a preferred arrangement as relative rotation with the two panels may cause the entire base to rotate so that it is no longer perpendicular to the panels, thereby reducing stability.

Applicants recognize the intended advantages of the embodiments described herein; for example, damaged fence supports can be repaired more easily and inexpensively, and damage to vertical supports is prevented. The spare parts of the previous embodiment may be about 25% of the repair costs of the existing solution (about $ 2.50). Accordingly, applicants' novel support is more cost effective and solves the above problems by allowing for quick replacement.

While the present invention has been described with reference to certain particular embodiments, various modifications thereof will be apparent to those skilled in the art without departing from the spirit and scope of the invention as outlined in the claims appended hereto. The entire disclosures of all references cited above are incorporated herein by reference.
