Description

BACKGROUND

This invention relates to a column protector for an industrial facility.

Warehouses, distributions centers, factories, and similar facilities often have large stock handling equipment such as fork trucks which frequently move stock into, out of, and around the facility. In some examples, facilities may have columns (e.g., support columns) which are located in areas commonly traversed by the stock handling equipment.

SUMMARY

As an operator navigates stock handling equipment through a facility, it is possible for the operator to cause the equipment to collide with a support column, potentially causing damage to the column and/or the equipment.

In a general aspect, a column protection apparatus includes a number of impact absorbing members, each impact absorbing member including a protrusion and a protrusion receiving opening. The protrusion of each impact absorption member is inserted into the protrusion receiving opening of another, different impact absorption member such that a column-receiving opening is formed through the impact absorbing members.

Aspects may include one or more of the following features.

At least some of the protrusions of the impact absorption members may be partially inserted into a protrusion receiving opening of another, different impact absorption member. Each impact absorbing member may include one or more grooves for receiving a portion of a securing strap. A top surface of each impact absorbing member may have a rounded shape. Each impact absorbing member may be substantially L-shaped. The protrusion of each impact absorbing member may include a protrusion alignment member and the protrusion receiving opening of each impact absorbing member may include an opening alignment member configured to interact with the protrusion alignment member to align the protrusion in the protrusion opening. The protrusion alignment member may include a groove and the opening alignment member may include a groove configured to receive the groove to align the protrusion in the protrusion opening.

At least one of the impact absorbing members may include a recess for accommodating a strap tightening tool. The impact absorbing apparatus may include a proximity sensing alarm for alerting approaching vehicles of an impending collision with the impact absorbing apparatus. The impact absorbing apparatus may include a rotatable outer shell for impact deflection. The impact absorbing members may be formed from a high density polyethylene (HDPE) material. One or more of the impact absorbing members may include a strengthening rib on an outer surface thereof.

Aspects may have one or more of the following advantages.

Among other advantages, the adjustable column protector is configured for snug and secure installation onto a wide range of column sizes.

The adjustable column protector is easily installed and offers 360 degree protection of a column from collisions.

The adjustable column protector provides damage prevention in that it protects the column, protects the equipment that hits may hit a column, it protects equipment operators, and it avoids scratching equipment and the associated equipment repainting.

The adjustable column protector can be used indoors or outdoors.

The adjustable column protector is abrasion resistant.

Other features and advantages of the invention are apparent from the following description, and from the claims.

DESCRIPTION

Referring to FIG. 1, an adjustable column protector 100 is installed on a column 102 (e.g., an I-beam support column). The adjustable column protector 100 includes four corner sections 104 (with only three visible in FIG. 1), sometimes referred to as ‘impact absorbing members,’ nested within one another such that a portion of the column 102 is fully enveloped by the adjustable column protector 100. The column protector 100 covers and protects both the corners and the sides of the portion of the column 102.

As is described in greater detail below, the column protector 100 can be adjusted to closely fit any column that has a size within a predetermined range (e.g., 8″ to 12″ columns) while still maintaining coverage and protecting both the corners and the sides of the portion of the column 102.

In some examples, the four corner sections 104 are held together using one or more straps 106 (e.g., ratchet ties, Velcro straps, cam straps, etc.) that are disposed in one or more grooves 108 of the corner sections 104.

Referring to FIG. 2, a side view of the adjustable column protector 100 shows two corner sections 104 abutting one another at a central plane 107. In this configuration, the column protector is adjusted to its smallest size (e.g., to fit an 8″ column). Each of the corner sections 104 has a flat bottom surface 105 such that the column protector 100 rests flatly on the ground.

Referring to FIG. 3, a top view of the adjustable column protector 100 shows the four corner sections 104 adjusted to closely fit the column 102, with little or no clearance between the column and the inner surfaces 314 of corner sections 104.

Referring to FIG. 4, each corner section 104 is a substantially L-shaped member having an outer surface 412, an inner surface 414, a protrusion 416, and a bumper 418 having a top surface 410 including a protrusion receiving slot 420.

In some examples, the outer surface 412 has a rounded shape for increased impact deflection. The inner surface 414 forms a right angle and is configured to rest against the column 102 when the adjustable column protector 100 is installed. The bumper 418 is configured to face away from the column 102 and to protect the corner of the column from the force of collisions with stock handling equipment. In some examples, the top surface 410 of the bumper 418 is rounded to prevent accumulation of debris and liquids (e.g., water).

In general, the protrusion 416 of each corner section 104 is configured for partial or full insertion into the protrusion receiving slot 420 of another, different corner section 104. Similarly, the protrusion receiving slot 420 of each corner section 104 is configured for partially or fully receiving the protrusion 416 of another, different corner section 104. In some examples, each corner section 104 is identical.

When the protrusion 416 is only partially inserted into the protrusion receiving slot 420 (e.g., when installed on a larger column), the sides of the column 102 are covered and protected by the protrusion 416.

In some examples, the protrusion receiving slot 420 includes one or more alignment ridges 422 for ensuring proper alignment of the corner sections 104 when the protrusion 416 of one corner section 104 is inserted into the protrusion receiving slot 420 of another corner section.

Referring to FIG. 5, in some examples, the protrusion 416 includes one or more alignment grooves 524 for receiving the alignment ridges 422 of the protrusion receiving slot 420 of another corner section 104 in order to ensure proper alignment of the two corner sections 104 when assembled.

Referring to FIG. 6, a top view of the corner section 104 shows the substantial L-shape of the member as well as the relative thicknesses of the protrusion 416 and the bumper 418.

Referring to FIG. 7, when the adjustable column protector 100 is installed, the four corner sections 104 are assembled such that each corner section 104 has its protrusion 416 in the protrusion receiving slot 420 of another, different corner section 104. Similarly, each corner section 104 has the protrusion 416 of another, different corner section 104 in its protrusion receiving slot 420. In general, the degree to which the protrusions 416 are inserted into the protrusion receiving slots 420 depends on the dimensions of the column 102.

In FIG. 7, since the adjustable column protector 100 is installed on a larger column (e.g., an 11″ column), the protrusions 416 of the corner sections 104 are only partially inserted into the protrusion receiving slots 420 of the other corner sections 104. However, the portion of the column 102 is still fully enveloped by the adjustable corner guard 100, with the protrusions covering the sides of the portion of the column 102 and the bumpers 418 covering the corners of the portion of the column 102.

Referring to FIG. 8, a side view of the adjustable column protector 100 shows two corner sections 104 with the protrusion 416 of one corner section 104 partially inserted into the protrusion receiving slot 420 of another corner section. In this configuration, the column protector is adjusted to a larger size, to fit a larger column 102 (e.g., an 11″ column).

Referring to FIG. 9, a top view of the adjustable column protector 100 shows the four corner sections 104 adjusted to have the inner surfaces 414 of the bumpers 418 closely fit the column 102, with little or no clearance between the corners of the column and the inner surfaces 418. In some examples, a space exists between the sides of the column 102 and the inner surfaces 630 of the protrusions 416.

Referring to FIG. 10, another example of an adjustable column protector 100 is installed on a column 102. The adjustable column protector includes four corner sections 104 (as is the case in the examples described above) nested within one another such that a portion of the column 102 is fully enveloped by the adjustable column protector 100. One or more of the corner sections 104 includes a strengthening rib 109 on its outer surface 412. In general, the strengthening ribs 109 increase the rigidity of the corner sections 104 and provide an alternative aesthetic appearance for the column protector 100.

In some examples the corner sections are made from a plastic material such as high density polyethylene (HDPE).

In some examples, a strap tightening tool can be used to tighten the straps 106 and secure the adjustable column protector 100 onto a column 102. In some examples the adjustable column protector 100 includes recesses for accommodating such a tool during a tightening process.

In some examples, all surfaces of the column protector, including surfaces other than the top surface 419 of the bumper 418, are shaped to ensure that liquids and debris shed off of the column protector.

In some examples, the column protector includes an exterior shell that can rotate upon impact in order to further dissipate the force of collisions.

In some examples, the column protector includes a proximity sensing alarm for warning equipment operators of an impending collision.

In some examples, extender members, each having a substantially planar shape, have an opening configured to receive a protrusion 416 of one of the corner sections 104 and a protrusion configured for insertion into a protrusion receiving slot 420 another of the corner sections 104. Such planar extender members serve to protect columns or other objects whose dimensions preclude the use of corner sections 104 alone.

While the above column protector is described as having only four corner sections 104, in some examples, a similar design using more or fewer corner sections can be used for other column shapes.

It is to be understood that the foregoing description is intended to illustrate and not to limit the scope of the invention, which is defined by the scope of the appended claims. Other embodiments are within the scope of the following claims.
