Abstract
Abstract Bed guard rotatable between elevated and lowered positions and slidable from the latter to a position underneath the bed. While elevated, it prevents accidental falling off, and when underneath, it allows facile patient management and movement of the bed through narrow passageways. Where the bed incorporates one or more electric motors to alter its configuration, the guard may additionally or alternatively include the patient controls for the motors.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
139 words
In a guard structure for a bed having: A. body restraining means for preventing unintended egress of an occupant from said bed, said restraining means being movable between an elevated and a lowered position; B. retaining means coupled to said restraining means for holding said restraining means in an elevated position; and C. release means coupled to said retaining means for disengaging said retaining means and allowing said restraining means to descend, the improvement comprising moving means for permitting said restraining means to move between an inner limit toward the center and an outer limit away from the center of a bed to which affixed, said moving means prohibiting motion toward the center of said bed beyond a predesignated point located between said inner and outer limits when said restraining means occupies a position substantially above said lowered position.
Claim 2
Dependent Claim
139 words
In a guard structure for a bed having: A. body restraining means for preventing unintended egress of an occupant from said bed, said restraining means being movable between an elevated and a lowered position; B. retaining means coupled to said restraining means for holding said restraining means in an elevated position; and C. release means coupled to said retaining means for disengaging said retaining means and allowing said restraining means to descend, the improvement comprising moving means for permitting said restraining means to move between an inner limit toward the center and an outer limit away from the center of a bed to which affixed, said moving means prohibiting motion toward the center of said bed beyond a predesignated point located between said inner and outer limits when said restraining means occupies a position substantially above said lowered position.
Claim 3
Dependent Claim
51 words
The improvement of claim 1 wherein: a. said predesignated point is substantially at said outer limit, and b. said inner limit is located sufficiently close to the center of said bed that said restraining means, when moved to said inner limit, is situated substantially beneath the mattress support of said bed.
Claim 4
Dependent Claim
33 words
The improvement of claim 2 wherein said restraining means is substantially rigid and further including intermediate holding means for holding said restraining means at a position intermediate said elevated and said lowered positions.
Claim 5
Dependent Claim
26 words
The improvement of claim 2 in a structure for affixation to a bed having electrical facilities wherein said restraining means includes controls for said electrical facilities.
Claim 6
Dependent Claim
27 words
The improvement of claim 4 wherein said moving means maintains said restraining means at a constant angle with respect to the surface on which said bed sits.
Claim 7
Dependent Claim
138 words
The improvement of claim 5 wherein: a. said moving means includes separate guiding means having an operative position where it prohibits motion of said restraining means from said outer limit toward said inner limit and an inoperative position where it allows such motion; b. said restraining means is pivotally attached to each of two arms; c. said arms each attach to and rotate about an axis passing through a pivot pin; d. a timing arm connects to each pivot pin; e. a timing link connects to both timing arms and undergoes motion as said restraining means lowers or elevates; and f. when said restraining means substantially reaches said lowered position, said timing link abuts and moves said guiding means from its operative position to its inoperative position to allow said restraining means to move toward said inner limit.
Claim 8
Dependent Claim
59 words
The improvement of claim 6 wherein said guiding means includes two members abutting against each other when said restraining means is at said outer limit and not substantially at said lowered position, said timing link moving at least one of said members out of abutment with the other member when said restraining means is substantially at said lowered position.
Claim 9
Dependent Claim
38 words
In a guard structure for a bed having electrical facilities, said structure having body restraining means for preventing unintended egress of an occupant from said bed, the improvement wherein said restraining means includes controls for said electrical facilities.
Claim 10
Dependent Claim
38 words
In a guard structure for a bed having electrical facilities, said structure having body restraining means for preventing unintended egress of an occupant from said bed, the improvement wherein said restraining means includes controls for said electrical facilities.
Claim 11
Dependent Claim
30 words
The improvement of claim 8 in a bed having at least one electrical motor to alter the configuration of said bed wherein said controls include means to activate said motor.
Claim 12
Dependent Claim
18 words
The improvement of claim 9 wherein said restraining means is movable between an elevated and a lowered position.
Claim 13
Dependent Claim
32 words
The improvement of claim 10 wherein said structure includes moving means for permitting said restraining means to move, between inner and outer limits, towards and away from the center of said bed.
