The present invention relates generally to ramps, and more particularly, to an apparatus, such as a ramp insert that may be capable of providing a continuous surface between rungs of a ramp.
Numerous types of ramps are often used to assist in the loading and unloading of objects from transportation vehicles. Particularly, trucks, vans, trailers and the like may utilize ramps to assist in the loading of objects such as ATVs, motorcycles, lawnmowers, etc. One common type of ramp may consist of a plurality of rungs whereby each rung is separated from a successive rung by an open space. The rungs are connected at or near the ends by rails. The successive rungs and the rails form a series of frame-like structures surrounding the central openings, similar to a ladder. Such a structure allows for loading and unloading of objects, such as ATVs, motorcycles, lawnmowers and etc., as long as the diameter of the tires of such objects is greater than the gap or distance between the successive rungs. In other words, the tires of the objects to be loaded must be greater in size than the central openings between the successive rungs of the ramp so that the object can be moved along the ramp.
Users frequently load many different types of objects onto the transporting vehicle. For example, a user may desire to use a single ramp to load a motorcycle and an ATV onto the transporting vehicle. However, the ATV and the motorcycle may have different sized tires so that the single ramp is unable to allow a user to effectively load and unload the ATV and the motorcycle. Accordingly, a user must connect a first type of ramp to the transporting vehicle to load the motorcycle, disconnect the first type of ramp, and connect a second type of ramp to the transporting vehicle to load the ATV. In addition, in such an example, the user must transport both types of ramps in order to be able to unload the ATV and the motorcycle.
Even if a single ramp is able to accommodate a few different types of objects to be loaded, the central opening between the rungs often causes difficulty in the loading and unloading of those certain objects. For example, even if the object, such as an ATV, has tires with diameters greater than the length of the central opening of the ramp, the tires may be difficult to move from one central opening to another central opening along the length of the ramp. The user must apply sufficient force to move the object from one central opening of the ramp, over the ramp rung and into the next central opening of the ramp.
Advantageously, the present invention provides an apparatus for insertion between rungs of a ramp to provide a surface for unloading and loading objects. The central opening between the rungs may be partially, substantially or completely filled by the apparatus to ease the loading and unloading of the object for the user.
The present invention is directed to a ramp insert for insertion between rails and/or rungs of a ramp. An embodiment of the present invention includes a body that may have an adjustable length. The body may include a first section that may include a track portion and a second section that may include a groove portion. The groove portion may be capable of fitting together with the track portion. The first or second section may be capable of slidably moving with respect to the other section via the track portion and the groove portion. The ramp insert may be placed between the rails and/or rungs of the ramp whereby the ramp insert may be adjusted to various lengths. Since the ramp insert may be adjusted to various lengths, the ramp insert may fit many different kinds of ramps having various widths.
While the present invention is described with reference to embodiments described herein, it should be clear that the present invention is not limited to such embodiments. Therefore, the description of the embodiments herein is merely illustrative of the present invention and will not limit the scope of the invention as claimed.
With reference to
The ramp insert 10 may include a first section 12 and a second section 14, as shown in
In an embodiment, the second section 14 may retract into and extend from the first section 12. In such an embodiment, the length of the ramp insert 10 may change depending upon the amount of the second section 14 that may be extended from or inserted into the first section 12. To this end, the ramp insert 10 may have a minimum length where the second section 14 is at a retracted position within, below, or above the first section 12. The ramp insert 10 may have a maximum length where the second section 14 is at an extended position from the first section 12. It may be preferable to have at least a portion of one of the sections 12, 14 overlapping the other section 12, 14 to provide strength to the structure of the ramp insert 10. While shown and described where the second section 14 may retract into or extend out of the first section 12, the present invention should not be limited to such an embodiment, and it is clearly contemplated and will be appreciated that the first section 12 may retract into or extend out of the second section 14.
The first section 12, for example, may have a track portion 30 for slidably moving the first section 12 with respect to the second section 14, as best shown in
In an embodiment, the track portion 30 may include ribs 32. The ribs 32 may extend from the top surface 20 of the first section 12. The ribs 32 may be of any appropriate shape or size. The ribs 32 may be integrally formed with the first section 12 which along with the geometric shape of the ribs 32 may allow the ribs 32 to transmit the load from the center of the ramp insert 10 to the ends of the ramp 100 and, in turn, to the ground or vehicle in which the ramp 100 may be attached.
In such an embodiment, the groove portion 34 may include grooves 36. The grooves 36 may be of any appropriate shape or size, such as being substantially similar in size and shape to the ribs 32, such that the sections 12, 14 may be extended and/or retracted. As a result, the groove portion 34 may have a similar rib-like structure 38 located between the grooves 36. The ribs 38 of the second portion 14 may be integrally formed with the second portion 14.
The track portion 30 and the groove portion 34 may provide structural support, when the ramp insert 10 is in use, such as standing on, walking on, or loading vehicles, ATVs, etc. As a result of the track portion 30 and the groove portion 34, the load bearing on the ramp may be transferred in a perpendicular direction to the top surface 20 of the ramp insert 10 and may be dispersed or otherwise absorbed by the ramp 100, including the rails 102 and the rungs 104.
As best shown in
The ramp insert 10 may further include a locking mechanism 24. The locking mechanism 24 may secure the first section 12 to the second section 14 to prevent movement and to permit movement of the sections 12, 14 with respect to each other. The locking mechanism 24 may be of any appropriate type of device capable of securing and locking the first section 12 and the second section 14 so that the length of the ramp insert 10 may be maintained. In an embodiment, the locking mechanism 24 may include use of fasteners, such as a screw 26 and a nut 28, for example.
The screw 26 may be keyed and threaded into the nut 28, as best shown in
Rotation of the screw 26 in a first direction may permit movement of the first section 12 and/or the second section 14 to change the overall length of the ramp insert 10. At a predetermined length, the screw 26 may be rotated in a second direction, such as the opposite of the first direction, for example, to secure the first section 12 and the second section 14 and thereby prevent relative movement of the first section 12 and the second section 14.
The ramp insert 10 may include a recessed portion 60. The recessed portion 60 may be of any appropriate shape or size. The recessed portion 60 may include a first wall 62 and a second wall 64. The recessed portion 60 may provide access to the locking mechanism 24. The first wall 62 and the second wall 64 may be positioned at a distance from one another that may be substantially similar to the diameter of the nut 28. Accordingly, rotation of the nut 28 may be prevented by contact with the first wall 62 and the second wall 64. To this end, the user may engage and disengage the locking mechanism 24 without holding the nut 28.
The locking mechanism 24 may permit the user to change or adjust the overall length of the ramp insert 10 to correspond to the distance between the rails 102 of a ramp, such as the rails 102 of the ramp 100 shown in
The first section 12 and the second section 14 may include cutout portions 70, 72, as shown in
In an embodiment, each side of the ramp insert 10 may include the cutout portions 70, 72 such that there may be two support members 22 in the ramp insert 10. Due to movement of the first section 12 and the second section 14 to create different lengths of the ramp insert 10, support along the length of the ramp insert 10 and between the first section 12 and the second section 14 may improve the strength of the ramp insert 10. The support member 22 may be a tubular member, a solid-bodied member, an I-Beam member, or any other appropriate type of member capable of providing support for the first section 12 and the second section 14.
The support member 22 may be attached to the first section 12 or the second section 14 by any appropriate means, such as being fastened via fasteners, such as screws, rivets, adhesives or the like, fore example. In a preferred embodiment, the support member 22 may be attached to the first section 12 via fasteners 76 through the fastener holes 74, as best shown in
In an embodiment, the support member 22 may be positioned on a distal end 16 and a proximate end 18 of the ramp insert 10. One of ordinary skill in the art will appreciate that the support member 22 may be positioned at any appropriate location on the ramp insert 10 as well as be constructed in numerous other appropriate manners. The present invention should not be deemed as limited to any specific type of support member 22, any number of support members 22, or any location of the support member 22.
As shown in
The blocks 80 at the first position or at the second position may be secured to the rails 102 and/or the rungs 104 of the ramp 100, as shown in
To ensure proper installation of the ramp insert 10 on the ramp 100, the ramp insert 10 may include an indicator 90. The ramp insert 10 may include an indicator 90 on the first section 12 and/or the second section 14, as shown in
In a preferred embodiment, the shape and size of the apertures 82 may be capable of frictionally engaging the protrusions 84 of the ramp insert 10. In a preferred embodiment, the blocks 80 may be separable from the ramp insert 10. In use, the blocks 80 may be engaged on opposing sides by the rails 102, the ramp insert 10 and/or the rungs 104. For example,
The ramp insert 10 may be made of any appropriate type of material as will be appreciated by one of ordinary skill in the art. In an embodiment, the ramp insert 10 may be manufactured from polypropylene plastic, or other suitable thermoplastic material such as by injection molding, for example. In such an embodiment, the ramp insert 10 may include impressions 92, as best shown in
In use, the ramp insert 10 may provide a structurally supportive surface at least partially filling an opening between successive rungs 104 of a ramp 100. As shown in
The width of the ramp insert 10 may be adjusted by moving the first section 12 and/or the second section 14. When the width of the ramp insert 10 is extended to the distance between the rails 102 and positioned on or in the rails 102 and/or the rungs 104, the locking mechanism 24 may lock the first section 12 and the second section 14 and secure the ramp insert 10 to the ramp 100. Before locking the first section 12 to the second section 14, the user may ensure that the first section 12 and the second section 14 are sufficiently within the rails 102 (or the rungs 104) by ensuring that the indicator 90 is adjacent to, aligned with, or within the edges of the rails 102.
As a result, the ramp insert 10 may fill the gap between the successive rungs 104 of the ramp 100 for walking, standing and moving a vehicle or other object along the ramp 100. The description in this and the preceding paragraphs should not be deemed as limited to a required order for securing the ramp insert 10 to the ramp 100. The preceding steps to securing the ramp insert 10 may be accomplished in various orders within the spirit of the present invention.
The invention has been described with reference to the preferred embodiment. Obviously, modifications and alternations will occur to others upon a reading and understanding of this specification. The claim as follows is intended to include all modifications and alterations insofar as they come within the scope of the claim or an equivalent thereof.
