Description

GERMAN

The subject of patent 847 958 is a double couch frame, which consists of two tubular steel frames of the same Dimensions, one of which after folding in the foot stirrup under the one with unfolded Stirrups standing other frame can be pushed. According to the patent 847 958, the foot stirrups are divided and the parts below the frame are hinged together so that they are after In the middle of the frame. There is an articulated connection between the stirrup parts from a tongue seated on the lower part, which engages in a longitudinal slot in the upper part and a Has elongated hole through which a pivot pin fastened in the upper part extends. To relieve the The pivot pin also has the lower part of a cup-shaped disc on which the lower end of the The upper part supports when the lower part is swung out.

The present invention seeks the articulated connection between the lower part and the upper part to enhance. It consists in the fact that in the upper part an outwardly displaceable, the pivot pin for the Lower part supporting joint bracket is guided and at the upper end of the lower part with an opened Position of the lower part in a corresponding conical bore of the upper part, conical pins that can be inserted is arranged. The conical pin creates a belt-free connection when the lower part is opened of high strength created between the two parts while relieving the joint, like the one with the cup-shaped disc according to the patent 847 958 can not be achieved. While in the design after the patent 847 958 the tube forming the upper part must be slit on one side so that the Lower part can be swiveled in, you get in the design according to the invention without slitting the Rohres and thus has the prerequisite for an unyielding, unyielding one that is closed on all sides on its circumference Conical connection.

In a known bed frame, the end supports have a detachably attached bracket. To the Shake-free connection of the two parts are provided by pins on the temple ends, on which elastically yielding ones Strips are attached to the side. These pins are inserted into parts of the end supports made of pipe, where the resilient strips fit snugly against the inner wall of the tube. With this type of construction however, the articulated connection between the two parts is missing. An articulated connection is also known between the frame and the legs of a bed frame with elongated holes at the top end of the legs have through which a pivot pin seated on the frame extends. In the position of use, the legs are held by shoulders, between the upper ends of the legs put a double coupon frame

will. This design does not provide any relief for the pivot pin and is therefore also part of the invention than the type according to patent 847 958.

In the frame according to the invention, the hinge bracket on its bearing the hinge pin is expedient End guided in a bushing of the upper part, which also contains the conical bore, while on at the other end a piston leading into your upper part is attached. Furthermore, the tops have at their upper ends bushings with conical bores, which are used to insert the with accordingly designed, conical pegs with removable brackets for mattress pads or the like. Such removable retaining brackets are known per se.

■ In the frame according to the invention, the height of the retaining bracket can also be greater than that when pushed underneath Distance measured between the upper end of the upper parts of the rack Frame and the frame of the frame above. Finally being useful about the mattress A blanket is stretched over the top frame and hangs over the edge of the mattress and has openings has through which the pins arranged on the retaining brackets or at the upper end of the upper part reach.

I ΌΒβ340 Fig. 3 on a larger scale the foot ends of the frame, partly in vertical section. The frame 1 of each couch frame, which is provided with an elastic covering, has stirrups 10 at its ends, which consist of vertical tubular upper parts 2 and lower parts to be described below. In each of the upper parts 2 bushings 3 and 4 with conical bores 5 and 6 are pressed in at the top and bottom. The bores 5 and 6 are used to receive conical pins 7 and 8, at the ends of the upper bracket 9 and the foot bracket 10, which have the flat crank 11 and form the lower parts. The pins 8 of the stirrups 10 have hinge pins 12 for the articulated connection of hinge plates 13, at the upper ends of which pistons 14 are attached, which are guided in the upper parts 2. The hinge plates 13 are dimensioned so that the pistons 14 are located close to the upper sleeves 3 when the foot stirrups 10 are pushed in. In this way, an elongated double guide is created in each upper part 2, one support of which is formed by the bore of the sleeve 6 guiding the hinge bracket 13 and extends over a length 15, while the second support is provided by the piston 14. The guidance is also retained when the parts 10, 12 and 13 are pulled apart and the foot stirrups 10 are folded in towards the center of the frame. One of the frames can be slid under the other, with rollers 16 on the stirrups 10 making it easier to move, as in the 847 958 patent. The relatively tall retaining brackets 9 are primarily suitable for supporting the mattresses 17 and bedding during night use and the armrests 18 during daytime use. The armrests 18 can be relatively high. The retaining brackets 9 are removed before the sub-couch is pushed in. The distance measured on the sub-frame between the upper end of the upper part 2 of the sub-frame and the frame 1 of the frame above it can therefore be significantly smaller than the height of the bracket 9. The nested couch frames are in daily use under one according to FIG Throw cover 19, which is provided with openings 20 through which the pins 7 of the retaining brackets 9 engage. As a result, the throw cover 19 is held and stretched. The conical pegs 7: can also be arranged at the upper ends of the upper parts 2 and the bushings 3 at the ends of the retaining brackets 9 in order to facilitate the placing of the cover 19 by pushing the openings 20 onto the pegs 7. If the removable Hältebügeli 9 are so low that 'they find space below the upper frame, their removal can be delayed. Patent claims: 1.
