1. Field of the Invention
This invention pertains to support pads to protect the knee when kneeling.
2. Description of the Related Art
Occasionally, a driver to must bend and kneel on the ground to inspect or clean the tires or wheels on his or her motor vehicle. When inspecting or cleaning the tires or wheels outdoors, many drivers prefer to place a protective rug or pad on the ground to protect their knees form dirt and water and to provide comfort. For some drivers, kneeling down and standing up can also be troublesome.
Earlier, the inventor attempted to solve these problems by developing a portable kneeling pad that includes a rectangular shaped rigid pad with a fixed support pole perpendicularly aligned at one end. Attached to the distal end of the support pole is a horizontal aligned hand grip, (see U.S. Design Pat. No. D592,411, issued on May 19, 2009). Although not relevant to the overall ornamental shape, the support pole was securely attached to one end of the pad and fixed in length creating an L-shaped structure that is difficult to store in the jack storage area in the trunk of a motor vehicle or on the shelf in a cabinet with other cleaning products.
Patients with back problems are told to rest horizontally on the floor. When they have to stand up, they are instructed to slowly roll to one side, tuck one knee under and then slowly rise and support themselves with their arms against a rigid support object or surface. When lying in the middle of a room, a rigid support object or surface to support the patient when trying to stand up is not always available. A flat kneeling pad with a rigid support pole that includes a horizontal grip handle at one end that a patient with back problems may use to help them move from a prone to a standing position would be highly desirable.
It is an object of the present invention to provide a portable kneeling support pad used to relieve discomfort on a person's knee when kneeling. The support pad includes a flat rectangular base with a resilient top surface. Attached near one end of the base is a detachable, perpendicularly aligned, support pole with a horizontally aligned grip handle attached to the pole's distal end. The base includes a support pole bore with a coaxially aligned stub partially inserted therein that extends upward and perpendicular to the base's stop surface. In one embodiment, the stub is designed to slide over the proximal end of the support pole thereby holding the support pole in a perpendicular alignment over the base. Attached to the distal end of the support post is a handle with a horizontal gripping member that enables the user to press against when standing to an upright position.
Disposed around the upper end of the stub is an adjustable clamp that when loosened, allows the user to selectively rotated the support pole 360 degrees around the stub and to selectively lower and raise the support pole into the stub to decrease or increase the height of the hand grip over the base to a desired amount. When the support pole is removed from the stub, the support base may be longitudinally aligned on the base and stacked against the top surface and an strap may be wrapped around the base and the support pole to hold them together.
In one embodiment, the pad's resilient top surface is made of chemical resistant material, such as nitrile rubber.
Referring to the accompanying
The support pad 10 includes a flat rectangular base 12 with two parallel side surfaces 14, 16, two parallel end surfaces 18, 20, a flat bottom surface 22 and a resilient top layer 24. Attached near one end of the base 12 is a perpendicularly aligned support pole 30 with a horizontally aligned grip handle 60 attached to the distal end of the support pole 30.
The support pole 30 is removably attached to the base 12 thereby enabling the support pad 10 to be disassembled and stored in a compact, space saving configuration. The support pole 30 includes an upper tube section 32 that is longitudinally aligned and mounted on a perpendicularly aligned stub 34 that extends upward from a bore 26 formed in the base 12. The stub 34 is hollow and longitudinally aligned and extends upward from the bore 26. A suitable adhesive 28 is used to securely attach the lower end of the stub 34 to the bore 26.
As shown more clearly in
In a second embodiment, of the support pad, indicated by the reference number 10′ is shown in
Attached to the stub 34′ is an adjustable clamp 50 that when activated, forces the stub 34′ inward causes the inside surface to press against the outside surface of the upper tube section 32′ of the support pole 30′ thereby fixing the support pole 30′ at a fixed location with respect to the stub 34′. As shown in
The grip handle 60 includes a horizontal support surface 62 designed to act as a gripping structure and as a support structure that will support the user when standing up. As stated above as and shown in
In both embodiments, the base 12 is made resilient material. In the preferred embodiment, the resilient material is made of nitrile rubber which resists caused by petroleum based liquids commonly found around a motor vehicle.
The base 12 is approximately 1 to 1½ inches thick and measures 12 to 18 inches in length and 5 to 8 inches in width. The stub 34 and support poles 30 and 30′ are both made of aluminum tubing approximately 1 to 1⅛ inches in diameter. The above description describe and the Figs. show the support pole 30 and 30′ sliding into the stub 34 and with the clamp attached to the stub 34. It should be understood, however, that alternatively the stub 34 and support pole 30 could be modified so that stub 34 slides into the support pole 30.
The pad 10 is distributed with an adjustable strap 75. The strap 75 may be wrapped and stored on the griping handle 60 or unfolded as shown in
In compliance with the statute, the invention described herein has been described in language more or less specific as to structural features. It should be understood however, that the invention is not limited to the specific features shown, since the means and construction shown, is comprised only of the preferred embodiments for putting the invention into effect. The invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted in accordance with the doctrine of equivalents.
