Siderail system for a bed
A siderail assembly for a bed, the bed having a patient support assembly, the siderail assembly comprising: a siderail disposed in a siderail plane; a mounting member for mounting to the patient support assembly; at least two parallel connecting arms, each connecting arm having a first end pivotably connected to the mounting member and a second end pivotably connected to the siderail, each connecting arm being adapted to pivot relative to the siderail about a first pivot axis and to pivot relative to the mounting member about a second pivot axis to allow the siderail to pivot along an arcuate path relative to the mounting member, the first and second pivot axes being parallel to each other and angled relative to the siderail plane to allow the siderail to move in a direction perpendicular to the siderail plane when pivoting.
1. A siderail assembly for a bed, the bed having a patient support assembly, the siderail assembly comprising: a siderail disposed in a siderail plane; the siderail comprising an outer face and an inner face, wherein the inner face includes a top portion that is generally planar and generally parallel to the siderail plane and a bottom portion that is angled towards the patient support assembly; a mounting member for mounting to the patient support assembly; at least two parallel connecting arms, each connecting arm having a first end pivotably connected to the mounting member and a second end pivotably connected to the bottom portion of the inner face of the siderail, each connecting arm being adapted to pivot relative to the siderail about a first pivot axis and to pivot relative to the mounting member about a second pivot axis to allow the siderail to pivot along an arcuate path relative to the mounting member and to move in a direction perpendicular to the siderail plane when pivoting, wherein at least one connecting arm is disposed in an arm plane, the arm plane being angled outwardly from the patient support assembly when the connecting arm is in a raised position.
2. The siderail assembly as claimed in claim 1 , wherein the connecting arms are adapted such that the first and second pivot axes are parallel to each other and angled downwardly relative to a horizontal plane to allow the siderail to pivot between a raised position in which the siderail is in a first siderail plane and a lowered position in which the siderail is in a second siderail plane parallel to the first siderail plane and spaced therefrom.
3. The siderail assembly as claimed in claim 1 , wherein each connecting arm is disposed in an arm plane, the arm plane being angled relative to the siderail plane.
4. The siderail assembly as claimed in claim 1 , wherein the siderail plane is vertical.
5. The siderail as claimed in claim 1 , wherein said siderail motion assembly includes a damper connecting the mounting member to at least one of the at least two connecting arms for damping the pivoting of the siderail.
6. The siderail assembly as claimed in claim 1 , further comprising a locking assembly movable between a locked position preventing the pivoting of the siderail and an unlocked position allowing the pivoting of the siderail.
7. The siderail assembly as claimed in claim 1 , further comprising an indicator for providing an indication of whether the locking assembly is in the locked position or the unlocked position.
8. The siderail assembly as claimed in claim 1 , further comprising a nudging assembly for preventing the siderail from remaining at an intermediate position in which a centerline of the connecting arms is at an angle of 90 degrees relative to the horizontal.
