A self contained patient transferring device for attachment to a transfer cart having a height-adjustable, horizontal platform sufficient to hold a patient and wheels for ease of moving the transfer cart from place to place, said patient transferring device comprising: a pair of slider mechanisms; a plurality of parallel disposed rollers outlining an upper track and a plurality of parallel disposed rollers outlining a lower track, all of said rollers journaled to and between said pair of slider mechanisms, the length of said rollers being sufficient to support a patient in a prone position along his length and the rollers of the upper track being displaced along the slider mechanism sufficient to support his width; a pair of superposed endless belts, one of said endless belts stretched around the plurality of rollers outlining the upper track and a second of said endless belts stretched around the pluraliTy of rollers outlining the lower track, both of said endless belts being of sufficient width to cover the rollers; said pair of slider mechanisms, the pairs of parallel disposed rollers and the pairs of superposed endless belts forming a rectangular frame member having a top and bottom and ends; a common drive means mounted on said frame member connected to said plurality of rollers outlining the upper track and said plurality of rollers outlining the lower track to selectively rotate the upper and lower tracks, said lower track rotating to drive both tracks to and from an extended position via said slider mechanism and said upper tracks rotating to place and remove the patient from the patient transferring device, a plurality of universal joining means, one for each of the plurality of rollers of both tracks and all located in the same vertical plane thereby forming two sections of the upper and lower tracks; and means to raise and support one section of the upper and lower tracks while keeping the second section in the horizontal position.
Claim 3
Dependent Claim
50 words
A patient transferring device according to claim 1 wherein the plurality of rollers of the upper track and the plurality of rollers of the lower track are located on the outer edge of the upper and lower endless tracks to support the patient without having rollers directly beneath the patient.
Claim 4
Dependent Claim
301 words
A patient transferring device for attachment to a transfer cart having a height-adjustable platform of a length and width sufficient to support a patient, a section of the platform being hinged across its width, and wheels for ease of moving the transfer cart from place to place, said patient transferring device comprising: a pair of slider mechanisms, each including an end plate and at least one slider cooperating with the end plate; means for fastening the slider of each of the pair of slider mechanisms to each end of the platform of the transfer cart along its width; a plurality of parallel disposed rollers outlining an upper track and a plurality of parallel disposed rollers outlining a lower track, all of said rollers journaled to and between the end plate of said slider mechanisms and each joined by universal joints at the hinged section of the platform of the transfer cart; a pair of superposed endless belts, one of said endless belts stretched around the plurality of rollers outlining the upper track and a second of said endless belts stretched around the plurality of rollers outlining the lower track, both of said endless belts being of sufficient width to cover the rollers and divided at the universal joints of the rollers to form a first and second section of the upper and lower tracks; drive means connected to said plurality of rollers outlining the upper track and said plurality of rollers outlining the lower track to selectively rotate the upper and lower tracks, said lower track rotating to drive both tracks to and from an extended position via said slider mechanism and said upper tracks rotating to place and remove the patient from the patient transferring device; and means to support the hinged section of the platform in the raised position.
Claim 5
Dependent Claim
301 words
A patient transferring device for attachment to a transfer cart having a height-adjustable platform of a length and width sufficient to support a patient, a section of the platform being hinged across its width, and wheels for ease of moving the transfer cart from place to place, said patient transferring device comprising: a pair of slider mechanisms, each including an end plate and at least one slider cooperating with the end plate; means for fastening the slider of each of the pair of slider mechanisms to each end of the platform of the transfer cart along its width; a plurality of parallel disposed rollers outlining an upper track and a plurality of parallel disposed rollers outlining a lower track, all of said rollers journaled to and between the end plate of said slider mechanisms and each joined by universal joints at the hinged section of the platform of the transfer cart; a pair of superposed endless belts, one of said endless belts stretched around the plurality of rollers outlining the upper track and a second of said endless belts stretched around the plurality of rollers outlining the lower track, both of said endless belts being of sufficient width to cover the rollers and divided at the universal joints of the rollers to form a first and second section of the upper and lower tracks; drive means connected to said plurality of rollers outlining the upper track and said plurality of rollers outlining the lower track to selectively rotate the upper and lower tracks, said lower track rotating to drive both tracks to and from an extended position via said slider mechanism and said upper tracks rotating to place and remove the patient from the patient transferring device; and means to support the hinged section of the platform in the raised position.
