Embodiment Construction

[0029] The present invention will be described more fully below in terms of an electrically adjustable mattress frame for a bed. However, it should be appreciated that the present invention is not so limited.

[0030] Such as figure 1 As shown, the mattress support comprises a frame 1 in which are mounted a backrest section 2 and a hinged footrest section 3 with a solid middle section between them. In this frame, a transverse shaft 4 for the backrest part 2 is mounted, said shaft 4 having a short arm 5 for fixing to this shaft 4 . Correspondingly, the axle 6 with the short arm 7 is configured for the footrest part 3 .

[0031] through as figure 2 Dual actuators 16 are shown to cause the movement of the backrest and footrest parts 2 , 3 . figure 2 An actuator system 17 is shown comprising a power off switch 14 shown in dashed box and an intermediate cable 13 connecting the power off switch to a control box 15 of the actuator 16 . The control box 15 is shown in dashed box...

Abstract

An off-mains switch (14) and a control box (15) for electrically adjustable articles of furniture, such as beds, chairs or tables, which automatically interrupt the connection to the power supply when the article of furniture is not adjusted, such that this will not constantly be under the mains voltage. These off-main switches require a multi-part cable which is rigid and thick. In the present structure (14, 15) a single two-part cable (13) is sufficient, as the off-mains switch (14) is configured such that the control signals between control unit / control box (15) and the off-mains switch are transmitted through a mains cable (13). A standard cable having two conductors is then sufficient. This means in turn that standard plugs may be used, and thus that the cable (13) may be connected to the power supply via an ordinary plug. Since, hereby, the off-mains switch may appear as a separate unit, production and logistics are facilitated.

Description

technical field [0001] The present invention relates to an off-mains switch and control box for an actuator system for use in conjunction with electrically driven articles of furniture. Background technique [0002] In order to avoid constantly supplying the mains voltage to local transformers of electrically adjustable and / or electrically driven furniture items such as beds, chairs or tables, so-called mains cut-off switches have been developed, When regulated, the mains shutdown switch automatically cuts the connection between the mains and the local transformer. Cut-off can take place via a relay located in the mains shut-off switch or a unit with a corresponding relay function. [0003] When adjusting the furniture, such as by operating a function key on a manual control associated with the furniture installation, or by separate actuation of the power cut-off switch via the manual control and / or directly to the power cut-off switch Facility to perform a function such a...
