Abstract
A lubrication cover, for a joint such as a hinge or other similar device, includes a body defining a cavity and at least one aperture. The body is made from a stretchable material and is sized to allow the cavity to fit snuggly around the hinge. The body preferably includes at least one tab to facilitate the placement of the cover around the hinge. In practice, a user places the cover around the hinge. Next, the user introduces a lubricant into the cavity through the aperture. The cover prevents the lubricant from being applied to an area other than on the joint itself, thereby eliminating the creation of a mess and damaging other objects. If left in place, the cover also ensures that the lubricant will be in close proximity with the hinge, and protects the hinge from foreign material such as dirt, water, and the like.
Description




TECHNICAL FIELD




The present invention relates to joints and more particularly, relates to lubrication and protection of joints such as hinges.




BACKGROUND INFORMATION




Noisy and squeaking joints, such as hinges, are a common and annoying problem. While it is possible to apply a lubricant to these noisy hinges, several problems still persist.




The first problem is that the lubricant, whether it is an aerosol or other spray type lubricant, a viscous grease type lubricant, oil, graphite, silicon, or white lithium grease, often creates a mess by dispersing to an area beyond the immediate hinge area. When applying the spray type lubricants, the user often applies too much, causing the lubricant to drip onto the door, doorframe, or flooring where it can permanently damage expensive carpets, woodwork, or tiles. While these spray type lubricants are easy to apply, the user often inadvertently sprays the lubricant on unintended areas such as the doorframe or the door itself, thus creating a mess or worse, damaging an expensive door or doorframe.




The viscous grease type lubricants also suffer from several problems. They are often very difficult and frustrating to apply, frequently forcing the user to apply the grease with his/her hands in order to get the grease into the desired location. Because of the difficulty in applying the grease, excess grease is frequently applied which can easily fall onto the floor or be smeared onto a passerby who accidentally brushes up against the hinge.




Accordingly, what is needed is a device to prevent the mess associated with the lubrication of joints such as hinges. The device should be relatively inexpensive, and should not require extensive modification or replacement of an existing joint. Moreover, the device should reduce the amount of maintenance involved in keeping a joint properly lubricated while protecting the immediate area from excess or overspray lubricant.




SUMMARY




The present invention features a lubrication cover for a joint. The cover prevents the mess associated with the lubrication of joints, such as hinges, and reduces the amount of maintenance involved in keeping a joint properly lubricated. The cover includes a body made from a stretchable material such as, but not limited to, rubber, plastic, neoprene, and synthetic materials. The body forms a cavity sized to fit snuggly over the joint when the cover is in a stretched position. The body also includes at least one aperture adapted to allow a user to have access to the cavity formed by the body.




Optionally, the body further includes at least one tab to facilitate or aid in the placement of the cover over the joint. In a preferred embodiment, the body includes a first and at least a second tab disposed on a first and at least a second end of the body respectively. The tab may be an integral element of the body or a separate element.




The aperture may include a lid, a cover, or a plug. Optionally, the aperture includes a raised protrusion such as, but not limited to, a conical shaped protrusion, to facilitate the introduction of a lubricant into the cavity. According to a one embodiment, the aperture includes an adapter adapted to be connected to a grease gun.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




A joint cover


10


,

FIGS. 1-2

, in accordance with the present invention, allows a user to easily and quickly lubricate a joint (not shown) such as, but not limited to, a hinge or any other device with moving parts. The joint cover


10


preferably includes a body


12


having at least one aperture


14


.




In practice, a user places the joint cover


10


around the intended joint. Using the aperture


14


, the user then introduces a lubricant into a cavity


16


formed by the body


12


. The joint cover


10


retains the lubricant in the cavity


16


, thus preventing the lubricant from creating a mess and damaging other objects such as walls, doors, doorframes, floors, clothing, and other objects. Once the lubricant has been applied, the cover may then be removed and used to lubricate another joint.




In another embodiment, the user may maintain the joint cover


10


on the joint thereby maintaining the lubricant in close proximity with the joint, thus ensuring that the joint will be properly lubricated and thereby reducing the amount of maintenance required to keep the joint in proper working condition. In this embodiment, the joint cover


10


also acts as a barrier to prevent foreign material such as dirt, water, and the like from coming in contact with and damaging the joint.




The body


12


is made from a stretchable material such as, but not limited to, plastic, rubber, neoprene, or any stretchable synthetic material. The body


12


forms a cavity


16


that is sized to be slightly smaller than the smallest joint that the joint cover


10


is intended to cover such that the joint cover


10


will fit snuggly around the joint. The exact dimensions of the joint cover


10


will depend on the dimensions of the intended joints to be covered, and are within the knowledge of one skilled in the art. Because the body


12


can stretch, a single joint cover


10


can fit a wide range of joints. As an example only, a joint cover


10


designed to cover a traditional residential door hinge could have a length of approximately 3.5-4.625 inches and a width of approximately 0.25-0.5 inches.




The body


12


may also include one or more tabs or protrusions


20


, FIG.


3


. The tabs


20


facilitate the stretching of the joint cover


10


around the joint. The tabs


20


may be molded into the body


12


, or may be a separate piece. While the tabs


20


are shown at the ends


22


of the body


12


, they


20


may also be disposed on the sides


24


as well.




The body


12


also includes at least one aperture


14


,

FIGS. 1-2

. The aperture


14


is used to introduce the lubricant into the cavity


16


. In one embodiment, the body


12


may include multiple apertures


14


(not shown) to facilitate even distribution of the lubricant within the cavity


16


when covering large joints or joints with complex elements. The aperture


14


may include a cover


18


such as, but not limited to, an opening, or a removable lid or plug to prevent the lubricant from escaping from the cavity


16


. Alternatively, the aperture


14


may be made from a resilient, stretchable material such that the aperture


14


forms a seal.




In a preferred embodiment, the aperture


14


,

FIGS. 3-4

, includes a raised opening. The raised preferably includes a conical-shape as shown. Alternatively, the conical-shaped raised opening may be inverted. The aperture


14


may include an adapter


26


, such as but not limited to a standard grease fitting, for connecting a grease gun (not shown) to facilitate the introduction of a grease-type lubricant into the cavity


16


. Alternatively, the adapter


26


may include an aperture (not shown) designed to facilitate the introduction of a spray tube of the type commonly found on aerosol type lubricants.




Accordingly, the present invention solves all the problems associated with the prior art. The joint cover


10


is easy to use and relatively inexpensive to manufacture. Moreover, the present invention can be used with existing joints without modification to the joint itself.




Modifications and substitutions by one of ordinary skill in the art are considered to be within the scope of the present invention, which is not to be limited except by the following claims.
