Description

Carriage with couch, use of a coil spring to support a rotary movement of a couch in a car

The invention relates to a car with a couch, in particular a railway carriage with a lounger and the use of a coil spring to support a rotational movement of a couch in a car, especially in a railway car according to the preamble of the independent claims.

It is known in cars with fold-down couches to support the couch in its rotational movement by a support mechanism to move the couch so easily from a lying position to a holding position can.

For example, US Pat. No. 4,279,203 A discloses a couch with a torsion spring. The torsion spring surrounds a hinge pin on which the couch is suspended and is connected at one end to the couch and connected at a second end to the partition wall of the carriage. As a result, the torsion spring supports the movement of the bed supported by the lying position in the holding position.

From DE 1135516 B a couch with a tension spring is known, which is connected via a chain on a couch so that the spring supports the couch in the movement from the lying position to the holding position.

A disadvantage of the known cars is the stress of space by attaching these support mechanisms and the connection of the spring with the lounger, which leads to a complex assembly of the lounger and the Unterstützungsmecha ^¬ mechanism in the car. It is the object of the present invention to provide a car with a couch, which avoids the disadvantages of the prior art and in particular to provide a carriage with a spring bed to support a rotational movement of the bed, in which the spring takes up little space and no complex installation of the lounger and spring in the car conditioned.

The object is achieved by a carriage with a couch and by the use of a coil spring to support a rotational movement of a couch in a carriage according to the independent claims.

According to the invention includes carriage of the carriage, in particular the rail, in particular a sleeping car, at least one deck, the special ^¬ a bed. The cart includes a support system for hanging the lounger. The support system rotatably supports the lounger. The Lie ^¬ ge is supported by a spring in the rotary motion. The spring is connected at a first end to the support system and connected at a second end to the couch. The spring is according to the invention wound in a plane.

Such a car has a reduction in the space required for the suspension of the lounger. In particular, the support system can be performed space-saving because of the wound in a plane, in particular in a plane perpendicular to the axis of rotation plane spring.

The connection of the second end of the spring with the couch can be designed as a direct connection or be designed as an indirect Ver ^¬ binding. In the direct connection, the spring is attached directly to the lounger. In the indirect Connection is the spring only indirectly, that is connected via other elements with the lounger.

In a preferred embodiment, the spring is designed as a spiral spring.

Thus, the spring can be accommodated to save space in the support system. In contrast to conventional springs, especially torsion springs, eliminates the comparatively long spring winding.

In one embodiment, the spring is made of spring steel.

The spring constant can be adjusted to the requirements by varying the spring thickness, width, the spring material used and the winding number.

The first end of the spring is mounted in a preferred embodiment ^¬ form directly on the support system.

The attachment of the first end of the spring on the support system allows a pre-assembly of the support system outside the car. Through this pre-assembly, the assembly in the car itself is simplified and shortened. The first end of the spring is angled in one embodiment.

By the angle of the first end of the spring, the spring can be supported on a support surface.

The support system in a preferred embodiment comprises a suspension plate. Thus, the support system is designed as a self-contained, independent element for suspending the bed. This allows easy mounting of the couch in the car. A suspension plate is an element which can be fixed by a buildin ^¬ actuating medium of another element, for example on a mounting structure.

In one embodiment, the support system has a pivot bearing for rotatably supporting a shaft.

The first end of the spring is in a preferred embodiment ^¬ form on a first support point, in particular part of the support system is on.

The spring is fixed on the support point by the pressure of the spring in the tensioned state. This allows a simple fixation of the spring at the support point, in particular on the support ^¬ system.

Thus, the connection of the first end of the spring with the support system can be particularly simple and space-saving. In a support point eliminates the need for additional, during installation manually attached parts, such as screws. Next, the number of parts of the support system are reduced, which in turn leads to a cost-effective support system.

The support system also includes a second support point in a preferred embodiment.

Thus, both right- as well as left-handed springs can be used with the support system. Depending on a sense of winding the Spring this is supported on the first or the other support point. The support system can thus - by choosing a corre ^¬ sponding Wickelsinns the spring - in beds that are rotated away from the right wall, as well as in couches, which are rotated away from the left wall, are used. This allows the same support system used for the entire car.

In one embodiment, the first support point and / or the second support point are formed in the suspension plate.

In one embodiment, the first support point and the second support point comprise substantially parallel surfaces, wherein the surfaces are arranged at a distance from each other, so that the first end of the spring can be positively inserted into the distance.

Thus, an additional hold of the spring is accomplished.

In a preferred embodiment, the first support point and / or the second supporting is formed by a projecting from the support point Tragsys ^¬ tem.

Thus, the support system is widened locally by the projecting support points and can support the angled first end of the spring at this point. The width of the rest of the support ^¬ system can thus be tailored exclusively to the diameter of the wound part of the coil spring. Thus, the support system can save space and cost-trained ^¬ to.

Alternatively, the width of the support system to the entire Fe ^¬ , ie on the angled first end and the disgusted part. The support points are then part of the support system and do not stand out from the support system.

In one embodiment, the first support point and / or the second support point are formed wider than the spring, so that they support the spring in its entirety.

The second end of the spring is mounted in a preferred embodiment ^¬ form on a part of the support system, which is connectable to the couch.

The attachment of the second end of the spring to a part of the support system allows the manufacture and assembly of the support system including the spring as an independent unit. An independent unit in turn allows easy installation of the couch in the

Cart, as the support system can be completed before the sunbed is installed.

The support system comprises in a preferred embodiment a rotatable shaft. The couch is connectable to the shaft and thus rotatably stored in the support system. The second end of the spring is attached to the shaft.

The attachment of the shaft in the support system allows easy connection of the spring to the shaft during assembly of Tragsys ^{¬ system} . The support system can be manufactured as a separate unit. When mounting the lounger in the car connecting the spring on the lounger is eliminated, whereby the assembly is simplified in the car.

In a preferred embodiment, the second end of the spring surrounds the shaft, in particular a driver of the shaft form-fitting and is attached to this. Thus, the second end is particularly simple, that is, without the use of an additional fastener, attached to the support ^¬ system, in particular to the shaft. This allows a simple design of the support system. The weakening of the shaft by a hole or a slot is eliminated, making the shaft can be made smaller and less space.

In one embodiment, the driver is formed by a rectangular section of the shaft.

Alternatively, the second end of the spring is inserted into a slot in the shaft and thus positively connected thereto. In one embodiment, the support system comprises a cover plate.

The cover plate closes the support system and protects it from contamination. In particular, the spring is covered by the cover plate.

In a preferred embodiment, the couch comprises a shaft tension set. The shaft of the support system can be inserted into the shaft tensioning set of the couch and can be connected to it.

The shaft tensioning set in the couch allows easy connection of the shaft of the support system to the couch. This simplifies the installation of the couch in the car. The shaft tensioning set further allows a simple, stepless adjustment of the spring tension of the springs of the support system, without the spring having to be accessible. Thus, the support system can be mounted in the car and then, when mounting the bed, the spring tension can be adjusted by the shaft tension set. Such a setting is infinitely possible by the use of a corresponding shaft clamping set. This makes a simple, quick installation of the couch in the car possible. Next, the spring preload can be easily and continuously adjusted during assembly.

In a further embodiment, the shaft is connected to the couch by a detachable, non-positive connection, such as a per-lock. In a further embodiment, the shaft is connected by a releasable, positive shaft-hub connection, for example by a coupling with the couch.

The couch can be rotated from a holding position to a lying position. The lounger is in the lying position perpendicular to a partition of the car. The couch is moved in the holding position against the partition, in particular, the couch is in the holding position parallel to the partition. In a preferred embodiment, a winding sense of the spring is formed so that the spring tension decreases in a rotation of the couch against gravity.

Thus, the rotational movement of the couch against gravity is supported by the spring force and thereby relieved. Such support of the rotational movement is particularly useful, since so the rotation of the couch can be made simplified. During a rotational movement of the couch with gravity, the spring tension increases.

In a further embodiment, the couch is folded up in the holding position against the partition, in particular, the couch is in the holding position parallel to the partition. In an alternative embodiment, the couch is folded down in the holding position against the partition, ^{insbesonde ¬} re is the couch in the holding position parallel to the partition.

In a preferred embodiment, the spring has less than 4 turns.

The design of the spring with less than 4 turns allows a particularly space-saving and cost-effective design of the Fe ^¬ and thus the support system.

In a preferred embodiment, the carriage further comprises a mounting structure. The support system can be attached to the mounting structure and the bed can be suspended from the mounting structure.

The mounting structure allows easy mounting of Tragsys ^{¬ system} in the car. In a further embodiment, at least two support systems can be attached one above the other to the mounting structure.

The mounting structure thus allows a simple design of the car with multiple couches.

Alternatively, the mounting structure comprises a first couch with egg ^¬ nem support system as described above and below and a second couch, which is rotatably suspended without the support system described above and below, in particular without spring. The second lounger is with a connecting element with the first

Lounger, which comprises a carrying system connected to a spring. A movement of the first couch and the second couch are coupled by the connecting member. This will be the second couch indirectly relieved by the first couch, in particular by the spring of the support system of the first couch.

Alternatively, one or more of the above and below mentioned couches is relieved on two sides by a respective support system with springs.

In one embodiment, a plurality of springs are connected in parallel in a support system.

This reduces the load on each spring. For example, a single spring can be made with fewer windings, thereby reducing the circumference of the spring.

Due to the double relief, the lounger can be moved very easily against gravity and / or the spring constants of the springs of the support systems can be made smaller. The mounting structure may be an integral part of the car and be attached, for example, to a carriage wall, in particular directly to the car body. A carriage may comprise a plurality of mounting structures, in particular comprising two mounting structures per carriage compartment.

In embodiments, the mounting structure is bolted, welded, riveted or glued to the body. Next to the ^{skilled ¬} man known connection ^types can be applied. Alternatively, the mounting structure may be attached to a partition wall. To solve the problem also leads to the use of a Spi ^¬ cal spring to support the rotational movement of a rotatably mounted couch in a car. The coil spring supports the rotational movement of the couch against a force acting on the couch gravity.

The support of the movement of the couch in a carriage by a coil spring allows a particularly space-saving execution of a rotational movement supporting mechanism.

The invention will be explained in more detail below with reference to Ausführungsbeispie ^¬ len in figures. Hereby show:

A wagon compartment 8 comprises a first partition 40 (shown on the left in FIG. 1), a second partition 41 (shown on the right in FIG. 1), and a carriage wall 43 perpendicular thereto Carriage compartment 8 further comprises a first mounting structure 46, which is connected to the carbody wall 43. At the ers ^¬ th mounting structure 46, a support system 14 is mounted. The support system 14 comprises a suspension plate 34 with Abstützflä- Chen 28, 30 for supporting a first end of a coil spring 19 (see FIG. 2).

The coil spring is covered by the suspension plate 34. A first end 20 of the coil spring 19 is mounted between the support surfaces 28, 30. The coil spring 19 is supported on the support surface 30.

By the support system 14, a couch 10 is rotatably suspended on the first mounting structure 46. At the first mounting structure 46, a further couch 10 is mounted analogously to the first couch 10 by a further support system 14. The further support system 14 corresponds in design and alignment to the already mentioned support system 14. The couch 10 are also on the other side, that is on the side towards the vehicle center, also rotatably ^¬ bar stored. The beds 10 can be so by a respective reclining position 38, in which the chairs 10 are substantially perpendicular to the partition wall 40 can be executed rotates against the partition 40 and so on depending on a stop position 36, in particular in a to the partition wall 40 in the We ^¬ sentlichen parallel holding position 36 are brought. A rotation 44 of this rotation is counter-clockwise and, viewed counter to the clockwise direction of rotation of the corresponding coil spring 18, from the first end 20 to a second end 22 of the carriage wall 43. The gravity of the bed 10 counteracting this rotation is at least partially compensated by the spring force of the spring 19. As a result, the rotational movement is relieved.

The couches 10 can from the holding position 36 against the rotation 44 and thus with the winding 42 of the corresponding Spiralfe- 19 are rotated back into the reclining position 38. In this case, the coil spring 19 is tensioned.

The carriage 1 comprises a further compartment 8 (in Fig. 1, right DAR provided) therein and a second mounting structure 47. At this second mounting structure 47 are two additional beds 10 supported by a respective support system 14 ^λ rotatable.

The couches 10 can be rotated by the reclining positions 38 against the direction of rotation 44 and against the winding 42 of the corresponding springs 18 by a clockwise rotation in the holding position 36. The counteracting this rotation of gravity of the bed is at least partially compensated by the spring force of the corresponding springs 19. As a result, the rotational movement is relieved.

The couches 10 of the second mounting system 47 can be rotated from the Hal ^¬ teposition 36 with the direction of rotation 44 and thus also with the Wickelsinn 42 of the corresponding coil spring 19 in the lying position 38 back. In this case, the coil spring 19 is clamped ^¬ . The two upper couches 10 of the first mounting system 46 and the second mounting system 47 each include a handle 48. With the help of the handles 48, the movement of the upper couch 10 can be made.
