Abstract

Abstract A support for a top cover for a tanning bed using three redundant straps spaced such that any two of the three will support the cover in the event of a failure of one of the other straps. Controls are provided for electrically controlling the operation of the motor for the top cover. These controls have the ability to raise the top cover automatically after a certain time delay or only after a certain sequence of manual actuation to provide improved control of the operation of the power top cover.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 312 words
A tanning bed and an apparatus for supporting, raising and lowering a top cover of said tanning bed, comprising: a frame having an upper support structure supporting a top member; a bottom member on which a user reclines while in said tanning bed, said bottom member having a plurality of ultraviolet lights and being connected to said frame and located directly below said top member; a rotatable axle coupled to said frame at an upper region; a motor coupled to said axle for rotating said axle to lower or raise said top member; a plurality of reels attached to said axle said plurality of reels including a plurality of reels fixedly attached to said axle and a variable position reel; a plurality of flexible first support straps coupled to said fixed reels at one end thereof and to said top member at another end thereof, all of said first support straps being the same length; a flexible second support strap coupled at one end thereof to said variable position reel means, said variable position reel means capable of being fixed to said axle at a plurality of angular positions and to said top member at another end thereof, said second support strap being of a length longer than said first support straps, said first and second support straps being of such a length that if fully extended from said axle and coupled to said top member, permitting said top member to be in the lowest possible position, said top member is positioned a predetermined distance above said bottom member, said predetermined distance being greater than the expected size of a user's body when said user is reclined on said bottom member; and a locking member means for locking said variable position reel means in a desired fixed position on said axle, said second support strap being coupled to said variable position reel.
Claim 2
Dependent Claim 312 words
A tanning bed and an apparatus for supporting, raising and lowering a top cover of said tanning bed, comprising: a frame having an upper support structure supporting a top member; a bottom member on which a user reclines while in said tanning bed, said bottom member having a plurality of ultraviolet lights and being connected to said frame and located directly below said top member; a rotatable axle coupled to said frame at an upper region; a motor coupled to said axle for rotating said axle to lower or raise said top member; a plurality of reels attached to said axle said plurality of reels including a plurality of reels fixedly attached to said axle and a variable position reel; a plurality of flexible first support straps coupled to said fixed reels at one end thereof and to said top member at another end thereof, all of said first support straps being the same length; a flexible second support strap coupled at one end thereof to said variable position reel means, said variable position reel means capable of being fixed to said axle at a plurality of angular positions and to said top member at another end thereof, said second support strap being of a length longer than said first support straps, said first and second support straps being of such a length that if fully extended from said axle and coupled to said top member, permitting said top member to be in the lowest possible position, said top member is positioned a predetermined distance above said bottom member, said predetermined distance being greater than the expected size of a user's body when said user is reclined on said bottom member; and a locking member means for locking said variable position reel means in a desired fixed position on said axle, said second support strap being coupled to said variable position reel.
Claim 3
Dependent Claim 44 words
The apparatus of claim 1 wherein said variable position reel means is rotatable with said second support strap coupled between said variable position reel and said top member for taking up slack in said support member and placing said second support member in tension.
Claim 4
Dependent Claim 35 words
The apparatus of claim 1, further including a first rotary switch means coupled to said axle and to said motor for turning off said motor when said axle has rotated a predetermined number of times.
Claim 5
Dependent Claim 17 words
The apparatus of claim 1, further including a reduction drive coupled between said motor and said axle.
Claim 6
Dependent Claim 71 words
The apparatus of claim 1, further including a connecting plate means and a bracket means for connecting each of said flexible straps to said top member; and means for adjusting the vertical connection between each of said flexible straps and said top member independent of each other to permit the top member to be aligned vertically and horizontally over said bottom member even though said bottom member is not perfectly horizontal.
Claim 7
Dependent Claim 295 words
A tanning bed and an apparatus for supporting, raising and lowering a top cover of a tanning bed, comprising: a frame member having an upper support structure supporting a top member; a bottom member on which a user reclines while in said tanning bed, said bottom member having a plurality of ultraviolet lights and being connected to said frame and located directly below said top member; a rotatable axle coupled to said frame at an upper region: a motor coupled to said axle for rotating said axle to lower or raise said top member; a plurality of reels attached to said axle; a plurality of flexible first support straps coupled to fixed reels at one end thereof and to said top member at another end thereof, all of said first support straps being the same length; a flexible second support strap coupled to a reel at one end thereof and to said top member at another end thereof, said second support strap being of a length longer than said first support straps, said first and second support straps being of such a length that if fully extended from said axle and coupled to said top member, permitting said top member to be in the lowest possible position, said top member is positioned a predetermined distance above said bottom member, said predetermined distance being greater than the expected size of a user's body when said user is reclined on said bottom member; a manually actuated "raise" button means for turning on said motor to raise said top member; and a delay circuit means coupled in series with said "raise" button and said motor for requiring that said "raise" button be depressed for a predetermined time prior to turning on said motor to raise said top member.
Claim 8
Dependent Claim 295 words
A tanning bed and an apparatus for supporting, raising and lowering a top cover of a tanning bed, comprising: a frame member having an upper support structure supporting a top member; a bottom member on which a user reclines while in said tanning bed, said bottom member having a plurality of ultraviolet lights and being connected to said frame and located directly below said top member; a rotatable axle coupled to said frame at an upper region: a motor coupled to said axle for rotating said axle to lower or raise said top member; a plurality of reels attached to said axle; a plurality of flexible first support straps coupled to fixed reels at one end thereof and to said top member at another end thereof, all of said first support straps being the same length; a flexible second support strap coupled to a reel at one end thereof and to said top member at another end thereof, said second support strap being of a length longer than said first support straps, said first and second support straps being of such a length that if fully extended from said axle and coupled to said top member, permitting said top member to be in the lowest possible position, said top member is positioned a predetermined distance above said bottom member, said predetermined distance being greater than the expected size of a user's body when said user is reclined on said bottom member; a manually actuated "raise" button means for turning on said motor to raise said top member; and a delay circuit means coupled in series with said "raise" button and said motor for requiring that said "raise" button be depressed for a predetermined time prior to turning on said motor to raise said top member.
Claim 9
Dependent Claim 12 words
The apparatus of claim 6 wherein said predetermined time is 5 seconds.
