Embodiment Construction

[0014] This embodiment relates to a hand control for electrically adjustable nursing and hospital beds with actuators for raising and lowering the backrest and footrest as well as raising and lowering the bed as a whole. For this purpose, the hand control is equipped with keys arranged in pairs, one for raising and the other for lowering.

[0015] The hand control comprises a trough-shaped plastic housing 1 in which is mounted a printed circuit 2 with a touch switch 3 , above which is a plate 4 with tongue-shaped keys 5 . The top side of the housing is fitted with a foil cladding 6 with graphics 3' which locate the key and its function. As a specific example, the hand control device has a locking function for the switch 3 , wherein the locking is effected by turning the knob 7 . Locking is effected in that the knob with two diametrically opposite legs actuates the electrical contacts of each other, thereby breaking the circuit of the two switches arranged opposite each other....

Abstract

An electric hand control, especially for electrically adjustable hospital and care beds and comprising a housing (1) constructed as a single trough shaped shell with a bottom and side walls, and wherein a printed circuit (2) with switches is mounted and above the switches there is a plate with tongue like shaped keys, and finally there is a cover foil (6) with indication of the keys and secured to the upper edge of the sides of the shell. As the housing is a single shell for one thing manufacturing of two difficult parts is avoided, for another assembling of these are avoided in the assembling process, and finally an assembling with a risk of leak is avoided. By further equipping the printed circuit and the cable with a plug (12a) the assembly is made easier. In this connection it is expedient that the spout (10) is equipped with an oval through going hole, so that the plug at the end of the cable can be led through the spout.

Description

technical field [0001] The invention relates to an electric hand control device, in particular for electrically adjustable hospital and nursing beds, as stated in the preamble of claim 1 . Background technique [0002] This hand control is made of two plastic shells combined to form a closed housing. Assembly can be done with screws, glue or ultrasonic welding. Before the housings can be connected together, it is necessary to plug in the printed circuit with the switch and the cable soldered on the printed circuit, which is led to a slot in the back of the hand control. In the upper plastic housing, there is usually a key in the form of an elastic tongue, and a foil cladding is mounted on top with a graphic that locates the key and its function. For hospital beds and nursing beds, when the hand control device is placed together with the hospital bed and nursing bed in a cleaning pipeline specially designed for cleaning and disinfection for cleaning and disinfection, it is ...
