Description

BACKGROUND OF THE INVENTION

Technical Field

This invention relates generally to heavy equipment machinery, and particularly to foot pedal guards for heavy equipment machinery, including backhoes.

State of the Art

Some types of heavy equipment, including certain types of backhoes, have an inherently dangerous condition in the foot pedal control system. In particular, some foot pedals are openly exposed on the floorboard of the equipment. The foot pedals are used to control any of various hydraulic systems, including raising and lowering attachments, such as loader bucket arms, backhoe booms, and the like. Because the foot pedals are openly exposed, it is possible to inadvertently engage the pedals, thereby operating the hydraulic systems to move the attachments. Many deaths, and thousands of injuries have occurred as a result of a laborer placing a tool, such as a saw, a chain, a water jug, or the like, into the cab of such a backhoe, while standing outside of the cab between the backhoe boom and the outrigger, due to the tool falling onto and engaging a pedal.

Accordingly, what is needed is a safety guard to cover the pedals to prevent inadvertent engagement of the pedals, while allowing free access to the pedals by an operator of the equipment.

SUMMARY OF THE INVENTION

The present invention relates to heavy equipment machinery, and particularly to foot pedal guards for heavy equipment machinery, including backhoes.

Embodiments of a pedal guard may comprise a generally U-shaped body having parallel inner and outer plates, the inner plate being disposed vertically between the foot pedal of a backhoe and the center control lever console, and the outer plate being disposed vertically between the foot pedal and the outermost inner surface of the cab. A front cross member plate is coupled between the front edges of the inner and outer plates, such that the inner plate, the front cross member, and the outer plate, enclose the inner and outer sides and the front edge of the right foot pedal of the backhoe, leaving open access to the foot pedal by an operator from the rear. The front cross member may be slanted over the pedal, such that the upper edge thereof is disposed directly above the pedal. The pedal guard is configured for attachment to the frame, the floorboard, the cab, or other suitable portion of the backhoe, or combination thereof, such as by welding, mounting hardware, or the like.

Some embodiments of a pedal guard may comprise a single unitary body configured to protect both the right- and left-side pedals of a backhoe. Such embodiments may comprise a single front cross member that extends across the entire width of the front edge of the floorboard of the backhoe, such that it protects the front edge of both the left and right foot pedals. The front cross member may be L-shaped, having a vertical portion that protects the front of the foot pedals and a horizontal portion that extends over the tops of the foot pedals. The horizontal portion may have an opening through which the center control lever console of the backhoe extends.

The foregoing and other features and advantages of the present invention will be apparent from the following more detailed description of the particular embodiments of the invention, as illustrated in the accompanying drawings.

Referring to the drawings, FIGS. 1 and 6 illustrate a pair of right- and left-side pedal guards 10 in accordance with an embodiment. FIGS. 2-5 are left-side, front, right-side, and top views, respectively, of a right-side pedal guard 10, in accordance with the embodiments of FIGS. 1 and 6. As shown, a pedal guard 10 may comprise a generally U-shaped body 12, the body 12 having substantially parallel inner and outer plates, 14 and 16, of steel sheet material, or other suitable material. As shown in FIGS. 6 and 7, while in use, the inner plate 14 may be disposed vertically between the foot pedal 28 and the center control lever console 24 of a backhoe, and the outer plate 16 may be disposed vertically between the foot pedal 28 and the outermost inner surface 26 of the cab of the backhoe. A front cross member 18 of similar steel sheet material, or other suitable material, may be coupled between the front edges 20 and 22 of the inner and outer plates, such that the inner plate 14, the front cross member 18, and the outer plate 16, essentially enclose the foot pedal 28 of the backhoe, leaving open access to the foot pedal 28 by an operator from the rear. The front cross member 18 may be slanted over the pedal 28, wherein the lower edge 30 thereof is disposed in front of and slightly below the front edge 32 of the pedal 28, or in direct contact with the floorboard 34 in front of the pedal 28, and the upper edge 36 thereof is disposed directly above the pedal 28.

In some embodiments, each of the inner and outer plates 14 and 16, as well as the front cross member 18, may be, without limitation, rectangular. In the embodiment shown in FIGS. 1-7, each of the inner and outer plates 14 and 16 has a corner removed to form resting surfaces 42. Resting surfaces 42 are configured to allow pedal guard 10 to rest on the floorboard 34 of a backhoe in such a manner as to allow the front cross member 18 to be slanted over the pedal 28, as described above and as shown in the drawings.

The pedal guard 10 may further comprise at least one of any of a variety of brackets 38 configured for securing the pedal guard 10 to any of the frame, the floorboard 34, the cab, or other suitable portion of the backhoe, or combination thereof, such as by welding, mounting hardware, or the like. For example, as shown in FIGS. 1-6, pedal guard 10 comprises a bracket 38 coupled thereto and configured for securing pedal guard 10 to the center control lever console 24 of a backhoe. Bracket 38, as shown, comprises an aperture 40 therethrough through which a mounting bolt may be inserted for the purpose of securing pedal guard 10 to the center control lever console 24.

It should be understood, that a pair of pedal guards, 10, according to the embodiment shown in FIGS. 1-7, comprise left and right pedal guards 10, wherein a left pedal guard 10 is a similar or identical mirror-image of a right pedal guard 10, the left pedal guard 10 being configured for use over a left-side foot pedal 28 of a backhoe and the right pedal guard 10 being configured for use over a right-side foot pedal 28 of a backhoe.

While in use, the pedal guards, thus disposed, as shown in FIGS. 6 and 7, thereby protect the foot pedals 28 from inadvertent engagement, such as by the dropping of a tool onto a pedal 28, while allowing free access to the pedals 28 by an operator from the rear.

As shown in FIGS. 8-11, an alternative embodiment of a backhoe pedal guard 50, in accordance with the present invention, may comprise a single unitary body configured to protect both the right- and left-side pedals of a backhoe. As shown in these figures, an embodiment may comprise a single front cross member 52, having opposed left and right ends 54 and 56, configured to extend across the entire width of the front edge of the floorboard 34 of the backhoe in a vertical disposition, to protect the front edges of both the left and right foot pedals 58 and 60. A pair of opposed left and right outer plates 62 and 64 are coupled to the left and right ends 54 and 56 of the cross member 52, respectively. When in use on a backhoe, the left and right outer plates 62 and 64 are disposed vertically to protect the outer edges of the left and right foot pedals 58 and 60, respectively. In addition, a pair of left and right top plates 66 and 68 are coupled to the left and right outer plates 62 and 64, respectively, as well as to the cross member 52, proximate the left and right ends 54 and 56 thereof, respectively, such that the left top plate 66 is orthogonal to the left outer plate 62 and orthogonal to the cross member 52 and the right top plate 68 is orthogonal to the right outer plate 64 and orthogonal to the cross member 52. When in use on a backhoe, the left and right top plates 66 and 68 are disposed above the left and right foot pedals 58 and 60, respectively, to protect the pedals from above. In this embodiment, the inner plates 14, of the embodiment shown in FIGS. 1-7, are not necessary, as the center control lever console 24 of the backhoe serves to protect the inner edges of the foot pedals 58 and 60.

Some embodiments may comprise left and right recesses 70 and 72 in the left and right rear edges 74 and 76 of the left and right top plates 66 and 68, respectively, as shown in FIGS. 9 and 11, for example, to accommodate the lower legs of an operator. Left and right shin guards 78 and 80 may be coupled to each of the left and right top plates 66 and 68 and partially surrounding the left and right recesses 70 and 72 thereof. The shin guards 78 and 80 each provide a substantially vertical surface 82 and 84 which an operator's lower legs may engage to protect the operator's lower legs from injury otherwise due to contact with the rear edges 74 and 76 of the left and right top plates 66 and 68. Embodiments with left and right recesses 70 and 72 are thereby able to cover and protect the tops of the foot pedals 58 and 60, while still allowing uninhibited access to the pedals by an operator.

Embodiments of a backhoe pedal guard 50, as shown in the embodiment of FIGS. 8-11, may further comprise a plurality of brackets 38 coupled thereto for securing the backhoe pedal guard 50 to a backhoe.
