Bed or couch frame

The innovation "concerns a bed or couch frame with a subframe and an upper frame resting on this, the at least one electric motor via a spindle drive steplessly raised and lowered or inclined section.

The purpose of the innovation is to build such a grate relatively cheap and easy with simple means. According to the innovation, this purpose is achieved in that the person lying on the grate himself conveniently switches and switchable electric motor with attached worm gear, and the threaded nut, which can be set in rotation via this gear, are arranged on a crosspiece which is attached to the at least approximately around both Läxigssocketühlen of the subframe its longitudinal axis is hinged so that the position of the threaded nut of the spindle drive when lifting, lowering or Tilting process occurring changes in position with their upper end on the raised or lowered or inclined section of the Follow the upper frame attacking threaded spindle and thus prevent jamming of the spindle drive.

The drawing shows two embodiments of the innovation object namely in

and 2 denotes the frame-like upper frame, the one on the head side The end of the grate at 5 on the subframe is arranged so that it can be inclined is that it can be gnawed more or less as needed; A headrest 4 can be tilted on the upper frame 2 hinged, which can be adjusted to the desired position. Transverse to the upper frame and the headrest are parallel to each other arranged extending resilient wooden strips 5, on which the mattress, not shown, rests.

At a distance from the end of the upper frame 2 on the jpuss side transversely to the frame a piece of pipe 6, in each of the ends Pin 7 protrudes in such a way that the pipe can rotate on this pin. The pins 7 are in the longitudinal sides of the upper frame frame attached. In the middle of the tube, the upper end of a threaded spindle is perpendicular to its axis and directed downwards 8 attached, which together with a tubular threaded nut 3 forms the spindle drive. The nut 9 protrudes through a bearing bush 10, which is attached to a cross piece 11. A chain wheel 12, pushed onto the tubular nut 9 from below and fastened thereon, is supported with its belongings at the lower end of the bearing bush 10 and, together with a collar 13 at the upper end of the nut sleeve 9, prevents longitudinal connections & mebups mother.

In the vicinity of each end of the cross piece 11 carrying the nut 9 is the upper end of a so-called rubber metal bolt attached, the lower end of each of these two bolts 14 is respectively firmly connected to a sheet metal tab 15. Each of these tabs 15 sits on a small wooden block 16, which is attached to the Underside of the longitudinal legs of the subframe is attached. In this way, the crosspiece 11 is due to the flexibility of the two rubber bolts 14 suspended on the lower frame so that they can pivot, that the spindle nut 9 mounted in it is able to follow the changes in position of the spindle axis.

At the bottom of the crosspiece 11, an electric motor 17 is attached to the over a worm gear 18 is able to drive a sprocket 19. A chain indicated at 20 provides the drive connection between wheels 19 & 12. Switching on, off and toggling

of the electric motor can the person lying on the grate convenient to make. When the spindle nut 9 is rotated in one direction, the spindle 8 is raised. Doing so tends the upper frame supporting the mattress is stepless. When the desired incline is reached, the motor is switched off. When turning in the other direction, the foot end of the upper frame lowers.

In the second embodiment according to ffif. 3, a cross piece 11 is suspended from the subframe 1 in the same way as in the first example, which cross piece is designed in the same way as in the first example. Here, too, the upper end of the spindle 8 is attached to a cross tube S , in each of the ends of which a pin 7 protrudes. In the case of the second example, however, the two pins each sit on one side 21 of a joint parallelogram consisting of four iron straps 21, 22, 23 and 24. The tabs 24 of the two parallelograms are firmly connected to the longitudinal legs of the lower frame 1. The tabs 23 are attached to the sides of a tiltable central section 25 of the upper frame and the sides 22 are attached to the outside of the sides of the raised and lowered foot section 26 of the upper frame.

If the spindle 8 rises while the electric motor is running, it rises the foot section 26 of the upper frame and the middle section of this frame rise to a steeper position. If the spindle 8 is pulled downwards with the drive reversed, the foot section 26 and the inclination are lowered of the middle section 25 is reduced. As part of the innovation, a similar device for tilting can also be used the head section, the upper frame are provided.
