Description

GERMAN

It is known to make the middle bed of three-bed sleeping car compartments so that it is not only Can be folded against the wall when not in use, but also in two different height positions able to take. Such a middle bed is in its lower position of use used when all three beds in the compartment are occupied. If, on the other hand, the upper bed is unoccupied and accordingly pivoted against the wall, then the middle bed is used in its upper position of use, so that ίο the user of the lower bed has more space available in height.

The invention relates to the central bed suspension for a three-bed room equipped in this way Sleeper compartment. The middle bed can thus in a known manner in a higher or a lower one Brought to the position of use and also folded against the partition wall when not in use, for which purpose it is mounted pivotably about a laterally offset web of a support bracket relative to the longitudinal center of the bed, which in turn, in order to reach the upper and lower position of use of the bed, it can be swiveled by approximately 180 ° the partition wall is mounted.

The conversion of the bed in question from one position of use to the other takes shape Difficult for the conductor because the bed frame has two degrees of freedom of movement during the conversion Has. It is particularly troublesome to move the folded up bed into the upper one with the carrying handle swiveled down Bring the position of use. Because the conductor has to hold the bed frame on both of its long edges grab and pull these edges off the wall first in the same direction. Then the outer edge must of the frame are settled, while at the same time the inner edge with unfavorable application of force on small Lever arm must be removed from the wall and lifted. In addition, the underbed den Prevents conductors from making their work easier by stepping close to the wall.

The invention is intended to make this work easier for the conductor. According to the invention attack the free ends of the legs of the support bracket in a known manner on springs that balance the weight of the bed, when the bed is moved from one position of use to the other. Through these feathers will be the forces that the conductor has to use to move the rear long edge of the bed frame with one hand moving up or down, so much diminished that the hand doing the work only needs to act in a guiding and controlling manner.

Beds for sleeping cars, in which weight compensation springs are provided for the movement from the position of use into the position of non-use, are known. These are beds that have a central bed suspension when not in use
for three-bed sleeping car compartments

Applicant:
Bremshey & Co., Solingen-Ohligs

Karl Heinz Eickhorn and Alfred Langer,

Solingen-Ohligs,
have been named as inventors

either folded against the wall or in a guide parallel to itself in one under the roof Subject to be promoted. In a bed of this latter type, a support bracket is provided between the legs of which the bed frame is pivotably mounted, but the pivot axis is centered on the bed frame and the bracket can be pivoted by about 90 °. All of these bed suspensions are however, beds that cannot be moved in two degrees of freedom and which therefore also provide compensation of the bed weight is not necessary when moving from one position of use to the other. in the In contrast to these known suspensions, the counterbalancing springs, which the invention provides, act not involved in moving the bed into the non-use position.

In one embodiment of the invention, which is characterized by structural simplicity, at least one is attached to the free end of one leg of the support bracket coaxially to its pivot axis Sheave provided for a pull rope attached to it at one end and that at the other End is connected to the anchored at a fixed point counterbalance tension spring.

An embodiment of the invention is shown schematically in the drawing. It shows

1 shows the middle bed of a three-bed sleeping car compartment in a perspective view and

2 shows the same bed in side view.

The bed is hinged on its long side 2 facing the partition wall on a support bracket, of two legs 5 arranged on both sides of the front edges of the bed frame and one of these rigidly interconnecting support rod 4 is made.

The free ends of the legs 5 are pivotably mounted on the partition wall 3 so that the support bracket 4.5 can optionally be brought into the lower or the dashed higher position of use drawn with full lines. Besides that, it can Bettl around the support rod 4 when not in use be folded up against the partition wall 3 and locked in this position. The support bracket 4, 5 is located is generally in its low position shown in Fig. 1. In the position of use, the bed 1 is on its front edge secured by folding hooks or other holding elements 7 on the side walls of the compartment.

In order to be able to easily move the bed 1 in the manner explained above, is at the free ends the legs 5 of the support bracket4, 5 each have a pulley8 provided, which is coaxial with the pivot axis 6 of the support bracket 4, 5. On the circumference of each pulley 8 is one end of a pull rope 9 is attached, the other end 10 of which is connected to a tension spring attached to a hook 12 of the compartment wall 3 is anchored. The pull rope 9 is wrapped around the pulley 8 once and the spring 11 so dimensioned that it is necessary to transfer the bed 1 from the lower to the higher position at least a considerable part of the necessary lifting work.

Because of the rigid connection of the legs 5 through the support rod 4, one can also use a single one stronger dimensioned tension spring and only one pulley 8 manage without the bed moving when moving canted. The parts 8, 9 and 11 of the weight compensation, which only take up little space, can be can easily be accommodated in the compartment niches and covered with cladding.

Claim 2 is a pure sub-claim which is only valid in conjunction with Claim 1 owns.

Claims (2)

. Patent claims: 1. Middle bed suspension for three-bed sleeping car compartments, where the bed can optionally be converted into a brought higher or lower position of use and also when not in use against the compartment wall can be folded, including a web offset laterally towards the longitudinal center of the bed a support bracket is pivotally mounted, which in turn to reach the upper and lower Usage position of the bed is mounted pivotable by approximately 180 ° on the partition wall, thereby characterized in that at the free ends of the legs (5) of the support bracket (4, 5) in per se known Way to attack springs (11) that balance the weight of the bed when the bed (11) is out of one position of use is brought into the other. 2. middle bed suspension according to claim 1, characterized by at least one on the free end of a leg (5) of the support bracket (4, 5) coaxially to its pivot axis (6) attached pulley (8) for one with its one end attached to it "pull rope (9), which with its other end with the at a fixed point (hook 12 - The compartment wall, 3) anchored weight compensation tension spring (11) is connected. . , Ia publications considered:
