FIELD OF THE INVENTION
The invention is in the art of a support for a person in a kneeling position that facilitates movement of the person from an upright position to a kneeling position and arising from the kneeling position to an upright position.
BACKGROUND OF THE INVENTION
Kneeler devices have been used to provide support when a person is kneeling and performing tasks such as cleaning a floor or object, painting, gardening or meditation. These kneeler devices have platforms or boards having cushions to support a person in a comfortable kneeling position. Handles associated with the platforms provide structures for aiding a person using the kneeler device in assuming a kneeling position and arising therefrom. Examples of kneeling aids and stools are disclosed in U.S. Pat. Nos. 2,318,416 and 4,850,069.
Bacterial touch surface contamination in hospital and medical clinic is associated with inadequate cleaning of equipment and rooms. Studies have been conducted to assess whether a lower environment bio-burden on critical touch surfaces would result in a lower risk of contracting an infection while hospitalized. Kneeler devices have not addressed bacterial contamination during use, transport and storage of the kneeler devices. There is a continuing need for a kneeler device that is easy to assemble without tools and effective to minimize microorganism contamination in an environment, including hospitals, medical clinics and physical therapy facilities.
The inability of a person to kneel after knee surgery is a cause of dissatisfaction. Kneeling can be a painful experience for persons with degenerative conditions of the knee both before and after surgery. No kneeling after surgery limits a person's ability to perform the activities of daily living. Some persons may need to kneel to return to perform to full employment and other persons may need to kneel to care for children or undertake leisure activities such as gardening and home improvement. Some religions have ceremonies that include the ability to kneel. All these activities contribute to improving a person's quality of life. Physical therapy intervention can improve a person's kneeling ability following knee surgery. Experienced therapist during routine clinic visits can provide a person with clear advice and instructions on kneeling and use of a kneeling device. Barriers to kneeling include scar position, numbness, range of flexion, involvement of other joints and pain. Kneeling ability with a therapist and a kneeling device can mitigate these barriers to a person's kneeling.
SUMMARY OF THE INVENTION
The kneeler of the invention has a platform and handles attached to opposite ends of the platform. The platform supports a cushion which functions as a rest for the knees of a person in a kneeling position. Bosses on corners of the platform have upwardly converging conical pockets. Feet attached to the handles have cone members located in the pockets that are in compression engagement with the bosses to firmly mount the handles on the platform. The handles can be removed from the platform by releasing the feet from the bosses. The assembly and release of the handles relative to the platform is accomplished with tools and separate connecting structures. The handles have antimicrobial copper alloy legs which substantially destroys microorganisms that adhere on the legs. The platform can also have antimicrobial materials that inhibit microorganism contamination. The kneeler has three components, the platform and two handles attached to feet, that can be assembled and taken apart in a minimum amount of time without tools or extra hardware. The handles can be identical or have different lengths for special needs. The kneeler has numerous uses, including but not limited to gardening, home and institutional cleaning, painting and carpet installation. Further use of the kneeler includes physical therapy exercising and assistance for infirmed and elderly persons.

Feet 461, 462 and 463 mounted on bosses 421, 423 and 424 have the same structure as foot 454.
Handles 412 and 413 are assembled on platform 411 by inserting the front feet 454 and 461 down through openings 441 and 436 to locate feet 454 and 461 below platform 411. Feet 462 and 463 are also located below platform 411. Handles 412 and 413 are separately moved laterally to locate the lower ends of the legs of handles 412 and 413 into adjacent pockets 433, 434, 438 and 439. Platform 411 is then moved down located the stems of feet 454, 461, 462 and 463 in tight compression engagement with bosses 421, 422, 423 and 424. Handles 412 and 413 are separated from platform 411 by moving platform 411 in an upward direction to release the holding action of the stems of feet 454, 461, 462 and 463 on bosses 421, 422, 423 and 424. Handles 412 and 413 are then laterally moved to move the legs of the handle out of pockets 433, 434, 438 and 439. Front feet 454 and 461 are then lifted up through openings 441 and 436 to separate handles 412 and 413 from platform 411.
