A telescopic bracket has a retracted state and an extended state. The telescopic bracket comprises a fixed assembly, a moving member, and a spring. The moving member is movably coupled to the fixed assembly to move along an axial direction of the fixed assembly, causing the telescopic bracket to switch between the retracted state and the extended state. The spring is disposed between the fixed assembly and the moving member to provide an elastic restoring force to the moving member, and the cross section of the spring could be a trapezoidal shape, a rectangular shape, a square shape, a parallelogram shape, or an unequal quadrilateral shape. An open-up device using the telescopic bracket is also provided.

A foldable bed frame includes left and right longitudinal stands. Each of the left and right longitudinal stands includes first and second longitudinal bars pivotally connected to a third longitudinal bar at first and second pivotal points, respectively. Each of the left and right longitudinal stands also includes first, second and third vertical legs fixedly coupled to or integrally formed at the first, second and third longitudinal bars, respectively. The distance between the first vertical leg and the first pivot point is different than the distance between the second vertical leg and the second pivot point such that when folded, one of the first and second vertical legs is disposed in an interior side of the folded left or right longitudinal stand with respect to the other of the first and second vertical legs.

The disclosure relates to a height-adjustable bed, in particular a hospital and/or nursing bed, comprising a bed frame, two bed end pieces, which accommodate the bed frame between said bed end pieces, and two telescopic lifting columns, which each interact with one of the two bed end pieces and have a supporting segment and a moving segment, wherein the lifting columns are arranged on the associated bed end pieces on the outside of the bed by means of the supporting segments of the lifting columns, and wherein the moving segment of a lifting column has a lifting column base, on which a supporting roller that can rotate about the vertical axis thereof is arranged, wherein the distance between the articulation point of the supporting roller and the associated bed end piece exceeds the rotation radius that can be described by the supporting roller about the vertical axis thereof.

A connector assembly for connecting a linear actuator to a telescopic housing includes an adapter part and a connector part. The linear actuator includes a telescopic tube system having an outer tube surrounding an inner spindle system. The telescopic housing has first, second, and third telescopic members arranged coaxially, with the third telescopic member arranged at least partially inside the first telescopic member and at least partially outside the second telescopic member. The adapter part is provided for attachment to the third telescopic part. The connector part is provided for attachment to the outer tube. The adapter part and the connector part have mechanical formations for producing a positive connection in the axial direction, which is arranged for connecting the outer tube to the third telescopic part.

A bracket is provided for an adjustable bed base that distributes the load of an actuator across a moveable panel of the adjustable bed. The bracket is coupled to a moveable panel of the adjustable bed, and has a width that is greater than one-third the width of the moveable panel.
