Device for converting benches into berths, in particular for railway compartments.

The invention relates to the overall arrangement of the device for the design of couchette compartments in railroad cars.

In general, two fundamentally different arrangements for couchette compartments are used in railroad cars, which yuf move into first or second class compartments.

As is known, the main difference between the two arrangements is that the first class compartments ge two berths arranged one above the other and the second class compartments each with three berths arranged one above the other on the long walls of the compartments.

This difference increases the comfort of the first class compartments in that the free space above the berths is noticeable

is larger than in the second class compartments.

To use the compartments just as well during the day as at night In the second class, the middle and upper mattresses are folded down against the long wall of the.-ib part during the day, with the lower mattress ice bench and the middle one Mattress serves as a backrest.

As the number of available lying areas in one move in advance is given, it can often happen, for unforeseen circumstances, that a large number of the berths, especially the second class remains unoccupied when the train departs. Then the comfort of the hoist can be in spite of the lower price these compartments cannot be improved because it is not possible to increase the free space above the mattresses.

To remedy this disadvantage, the invention proposes a new device ₉ to change the same design of the compartment into a compartment with 2x3 berths or one with 2x2 berths, with the upper and middle mattresses for use during the day can be folded away as backrests.

The compartment designed according to the invention with four or six berths for the night has on each long side of the compartment a top mattress that is in two horizontal, firm layers for the night, one higher and one lower and one for the day Backrest position can be brought, also a middle mattress, in a fixed, horizontal position, in an upwardly inclined position and in a downward one for the use of the. Compartment can be folded during the day «, After all, that has., Bteil a fixed or adjustable lower mattress is more common Kind as a bench.

According to FIGS. 1, 2 and 3, the two long sides of the compartment each carry three mattresses 1, 2 and 3 lying one on top of the other.

The lowermost mattress 1 serves as a bench during the day and is by a fixed base 4 on the floor 5 as well as on the Bedding 6 of the compartment attached. TJm the usual / .. outside To correspond to the lower mattress, the lower mattress 1 can be arranged so that it can be moved horizontally Transverse direction is possible.

The middle mattress 2 is at the level of the head cushion 7 and is folded down around a pin 8 during the day as a backrest. The pin 8 is on the one hand on the Longitudinal frame 9 of the mattress 2 and on the other hand attached to the longitudinal wall 6 of the compartment. This joint 8 has a locking device for the pivoting movement of the mattress 2, which is not shown in the drawing. It allows three positions the mattress 2, namely an ötwa vertical position (see Fig. 3), a horizontal position (see Fig. 1) and a upwardly inclined position (see Fig. 2). The locking device can be supported by a handlebar 10, which has one end is hinged to the center of gravity 11 of the mattress 2 and at the other end to a point on the side wall of the compartment, which lies under the pin 8.

This locking device can, as the drawings show, have a slide rail 13 with notches to support the handlebar 10, in which a slider attached to the lower end of the handlebar 10 slides.

The upper mattress 3 is through on the longitudinal wall of the compartment a mechanical device attached, which makes it possible that the mattress 3 a high horizontal position (see Fig. 1), a deep horizontal position (see Fig. 2) and a vertical position

(see p. 3).

In the illustration according to S ¹ Ig. 1 the three mattresses are in the use position for the night, which corresponds to a compartment with 2x3 mattresses. The top mattress 3 is in its high horizontal position and the middle mattress 2 is in a horizontal position. In this position, the space between the mattresses 1, 2 and 3 and the distance between the top mattress 3 and the ceiling of the compartment is approximately the same.

TIm from the arrangement according to * 'ig. 1 to that according to S ¹ Ig. 2, which corresponds to a compartment with 2x2 berths, only the top mattress 3 and the bottom mattress 1 are used. The top mattress 3 is brought into its somewhat lower horizontal position by removing it from the ceiling of the compartment. Then the unused mattress 2 is tilted upwards, thus increasing the free space above the bottom mattress 1.

The position at days according to FIG. 3 is obtained by the. brings top mattress 3 into its top horizontal position and then around the axis 12, which lies on the compartment wall and serves as the pivot point of the mattress 3, folds down. The postponement the .Mattress 3 is required so that the top mattress 3 does not overlap over the mattress 2 after one this has folded down around the tilting device 8.

It should be noted that the middle mattress 2, which then serves as the backrest, is slightly inclined. This can be achieved, for example, by placing the slide on the lower End of the handlebar 10 in the lowermost notch of the slide rail 13, limiting the movement downward, engages and the bottom mattress 1 has removable armrests 14 that can be attached to the Days can hang.

Figs. 4, 5, 6, 7 and 8 show the on the two ötirnseiten ■ the mattress 3 arranged mechanism through which the top Mattress 3 can occupy the two fixed horizontal layers and the position folded against the partition wall. He exists essentially consists of two slide rails 16 and 17 »the. vertical or slightly inclined to the vertical. They are staggered in their altitude, one with respect to the other, i.e. an upper slide rail 16 and a lower slide rail 17 are provided, in each of which a slide 18 and 19 slide can ·

The slide rails 16 and 17 have one at each of their ends lock 20, 21, 22, 23 to be actuated for the sliding piece assigned to each slide rail.

The slider 18 (Fig. 6) is rotatable about an axis 24 on the top mattress 3 attached in the vicinity of its longitudinal frame 25. The slider 19 includes an axis 26 around which the lower The end of the lever 27 rotates, the other end of which pivots about an axis 28 which is fixedly arranged in the center of gravity of the mattress 3.

The arrangement and proportions of the slide rails 16 and 17, of lever 27 and axles 24 and 28 are dimensioned so that: in the case where the sliders 18 and 19 are fixed to the upper ends of the slide rails 16 and 17, the mattress in the upper horizontal position (Fig. 4), in the case where the sliders 18 and 19 are at the lower ends the slide rails 16 and 17 lie, the mattress 3 in the lower horizontal position is located (Fig. 8) and in the case in which the slider 18 at the upper end of the slide rail 16 and the slide 19 are fixed to the lower end of the slide 19, the mattress is in the vertical position, (Fig. 6).

in Fig. 9 an embodiment of the mechanism is shown,

one of which is attached to each end face of the top mattress 3. In this embodiment it is possible to set two horizontal positions and one backrest position of the mattress 3 as required. The lower end of the slide rail 16 and the upper end of the slide rail 17 are delimited accordingly by an oblique round recess 30, y \ in the form of a saddle button, which are arranged opposite each other in the space between the two slide rails 16 and 17.

The lower end of the slide I7 is rounded limited to acting as an end stop of the movement of the slider 19 serves, while the upper end of the slide rail 16 a Latch (Fig. 10) which is secured by a latching device is operated. This carries an approximately semicircular bolt 32 which is arranged to be rotatable about an axis 33 which is attached to the compartment wall 6 * This latch 32 can by a lever 34- (Fig. 9) via a connecting rod 35 are actuated, the actuation being counteracted by a spring 36, which closes the bolt 32 in the locked position keep looking. The movement of the bolt 32 is limited and in the locked position by a bend 37 on the longitudinal edge of the slide rail 16.

This device works as follows: In the horizontal lower position (FIG. 9, dashed lines) the slider 18 lies in the recess 30 of the slide rail 16, while the slider 19 rests on the rounded portion 38, the its downward movement is limited in the track rail I7. There the hold of the slider 18 in the recess 30 is secured is, in terms of the horizontal transverse force resulting from the Moment of vertical downward forces exerted on the mattress, e.g. the weight of the mattress and of the traveler result, secured by the axis 26 and the lever 27.

, The transition of Matr _a Tze 3 from the lower horizontal position in the back tilted position by first exerting a horizontal thrust in the direction of the partition wall 6 on the mattress, such that the slider comes out of its recess 30 out 18th A vertical downward pressure is then exerted on the outer edge 39 of the mattress 3 in order to pivot it about the axis 28. The purpose of this pivoting is first of all to push the sliding piece 18 upwards along the sliding rail 16 until it latches into the lock at the end of its path. During this movement, the lever 27 pivots about its axis 26 and leans itself against the side wall 6 of the compartment at the same time as the mattress 3.

The stability of the reclined position of the upper mattress 3 is ensured by its own weight, its torque , which is fixed with respect to the axis 24 by the lock, tends to push the mattress 3 against the longitudinal wall 6 to keep the compartment ajar.

In order to bring about the high horizontal position of the mattress 3 starting from the position of the backrest, it is pivoted mn the axis 24, which is determined by the lock, upwards. The slide 19 slides in the slide 17 up to its upper end and comes into the recess at the end of its way 31 to the intervention. The weight of the mattress 3 and possibly that of the passenger will suffice to place the slider in the recess 31 and the mattress 3 in the uppermost horizontal Able to hold.

Moving the mattress back from the top horizontal position into the folded back position of the backrest is achieved by first pressing on d. < ^Λ luattress exerts a push upwards in order to loosen the sliding piece 19 * "« of the recess 31. Then you can

- 9 509819/0858

tilt the mattress back, pivoting about the axis 24.

In order to bring about the lower horizontal position of the mattress starting from this position, it is sufficient to move the sliding piece 18 to be unlocked by means of the lever 34 ·, in which case the mattress comes into the low horizontal position by itself.

It should be noted that the mattress, in order to get from one horizontal position to the other, necessarily through the backrest position must go through.

It should also be noted that for uniform movement of the The lever 27 is fixed by a transverse rod 41 on the arrangements of the mechanism provided on both end faces of the mattress are connected. To save space, this crossbar 41 is offset from the side wall of the compartment, namely by angled extensions which are made in one piece with the lever 27.

FIG. 10 shows schematically the locking mechanism for FIG. 9 on an enlarged scale. The semicircular bar 32 is over its sand is extended by a three-angled piece 42, the central angle 43 of which is in the axis of symmetry of the bolt 32 lies.

This bolt 32 has a penetrating one in its center Axis 33 in a bearing 45 which is provided in a support piece 46 which is firmly attached to the slide rail 16, wherein the support piece 46 and the slide rail 16 of the side wall 6 of the compartment are fixed. The bolt 32 also carries a vertical bolt 36 'around a connecting rod 35 One end is pivotably attached, the other End is hinged to the lever 34 (Fig. 9).

A spring 36 is attached to the connecting rod 35, which

- 10 5G9 819/0858

seeks to hold the bolt 32 in the locking position. The path of the bolt 32 is limited, with the bend 37 on the longitudinal edge of the slide rail 16 in contact ■ is coming.

To facilitate understanding of the "interlocking device, it is in the state of locking in solid lines and shown in dashed lines in the unlocking.

When locking, the bolt 32 lies over the slide rail 16 and holds the slide 18 firmly. The unlocking takes place in that the connecting rod 35 by means of the Lever 34. (Pig, 9) moved downwards, this movement rotates against the resistance of the spring 36 the bolt 32 until the Edge 47 of the bolt is against the lateral bend 37 the slide 16 sets. In this position, the slider 18 is freely movable and can move along the slide rail 16 slide along.

It is useful to make it clear that the bolt 32 when plucking an action on the lever 34, through the action of the Spring 36 is in the locking position.

An important advantage of this arrangement is that the locking of the slide 18 is automatically maintained, without actuation of the lever 34 necessary for the case that an adjustment operation of the device enables the uppermost mattress 3, for example from the lower horizontal one To move into the leaning position.

In fact, the slide 18 moves along the slide 16 upwards and comes to a stop on the end face 47 of the angular part 42 of the bolt 32 »by

- Π 509819/08 5 8

it this against the action of the spring 36, by this rotates into the open position and the slide 18 is the path free, its movement finally through the upper Part of the slide 16 is limited. In this position of the slide, the seal 32 returns to the locking position by the action of the spring 36.

The two levers 34 that lead to the two actuating devices Belonging to the top mattress are firmly connected by a connecting rod that allows smooth movement the bolt 32 secures. The simultaneity of solving the Locking can then be achieved in that the end face of the two semicircular bolts 32 in the The longitudinal direction of the lateral bends of the slide rails 16 concerned brings about a certain for the lever Bring about the opening position.

It should also be noted that for the middle mattress 2, instead of the pivoting device, a device similar to that of FIG locking described here e.g. after #ig. 9 use k'inn, with which the middle mattress is two horizontal, in its height can assume different »positions and a reclined position of the backrest. In this case the middle one is Cattress 2 in the lower horizontal position if you need an Alieil with 2x3 berths; but she is except for use, in their higher position when you have a compartment with 2x2 berths required.
