Embodiment Construction

[0023] Exemplary embodiments relate to a hand control for a nursing care cot having adjustable back and leg sections. figure 1 The upper part 1 of the hand control is shown, which is assembled with the lower part (not shown in the figure) by ultrasonic welding. As shown, the hand control is equipped with 6 keys arranged in pairs, of which the two top keys 2a, 2b activate the back part and the two middle keys 3a, 3b activate the leg part. The two bottom keys 4a, 4b activate the back and leg sections simultaneously. The right row of keys 2a, 3a, 4a raises the section, while the left row of keys 2b, 3b, 4b lowers the section. The front of the upper part 1 is covered with a sheet indicating keys.

[0024] Such as figure 2 As shown, the elastic parts 2'a, 2'b, 3'a, 3'b are used as parts of the key, that is, the circular brick-shaped block 5 at the end of the handle 1 is arranged in the upper part under the thin sheet.

[0025] Below the key there is a small switch 7 in the for...

Abstract

In electrically adjustable hospital and nursing beds there is a varying need for blocking certain adjustments of the bed. This blocking option is incorporated in the handset for the bed. The handset comprises a plurality of electrical switches (7) having an axially movable activating means (7") in a housing (7'), said activating means protruding a distance from the top of the housing. Above the activating means there is a likewise axially movable key which when being pushed down toward the switch steps on the activating means and presses it inwards toward the housing to activate the switch. A blocking means (12) may be moved from a parking position to a locked position, in which it partly rests on the upper side of the housing of the switch and partly serves as a stop for the overlying key at a level above the activating means of the switch in the rest position.

Description

technical field [0001] The invention relates to an electronic hand control device, especially for an electronically adjustable hospital bed or nursing bed. Background technique [0002] For examples of adjustable hospital beds, reference is made to patent EP 0 488 552 A1 to Huntleigh Technology plc and US 4 425 673 to B-W Health Products, Inc. Typically, there are two control methods for the bed, one is the manual control device, through which the patient can adjust the mattress support structure to the desired position, and the other is the controller at the end of the bed, through which the medical staff can The controller enables adjustments to the couch, including adjustments beyond those the patient is able to perform. At the same time, the medical staff can prevent medically impermissible adjustments for a particular patient, so that the patient cannot inadvertently move into an impermissible position, for example lifting a leg part if the leg bone is fractured.
