    专利说明:

    The invention relates to a device for locking a pivoting protective device, such as a safety bar, a chair for a chairlift, with cooperating projections, one of which is connected to the frame of the chair and the other with the protection device.
    Chairlift safety devices, such as safety bars or weather protection hoods, must be kept stable in this position when in the fully opened or fully closed end position, which can be done by gravity and supported by springs or locking mechanisms. Inadvertent opening or closing of the striker should be prevented anyway.
    A generally valid setting for a variety of versions of chair models, such as with and without weather protection hood, with or without locking system and the like, is practically impossible for many reasons. Such reasons include, for example, inclination differences, shocks and vibrations on the track, different weights, manufacturing tolerances, temperature changes and the like.
    The invention is therefore based on the object to provide a device with which protective devices are held securely in a certain position and yet can be opened under defined conditions.
    This object is achieved with a device having the features mentioned in the fact that at least one of the projections is resiliently mounted and that on the projections sliding surfaces are arranged, which allow a sliding past the projections to each other in both directions.
    For example, if a safety bar in the closed
    Position in which it extends across the legs of the passengers and thus secures them on the chair, is locked in this end position with the device according to the invention, then engage behind each other, the two projections, and the safety bar is held in this way. If the safety bar should be opened, the projections must be moved past each other, whereby the force of the one projection, the force can be adjusted relatively accurately, which is required to move the safety bar from its closed end position to the open position.
    According to the invention it is possible that the safety bar is biased by a spring, for example a tension spring in the open position, which facilitates the opening of the safety bar as soon as the projections were moved past each other. The system according to the invention can be set, for example, so that an opening force of about 20 to 30 N acts by the tension springs in the closed state of the safety bar. If the safety bar is to be opened only with an additional opening force or hand force of 30 N to be applied by the passengers, the spring force of the projection must exert a holding force of a total force of about 50 to 60 N (measured at the front of the safety bar on which the passengers attack) corresponds.
    At the same time, however, the device according to the invention also prevents the safety bar from unintentionally falling into the end position and being held therein. Namely, the safety bar by vibrations or other forces or, for example, the automatic closure of the weather protection hood (with empty vehicles), which moves the safety bar, moves towards the lower end position, then prevents the device or the abutting projections in reaching the whole closed end position, since the spring force of a resilient projection is not overcome. As a result, the safety bar can automatically reopen or rest against the closed weather protection cover and be opened again at the same time.
    Preferred embodiments of the invention are subject of the dependent claims.
    Further features and advantages of the invention will become apparent from the following description of a preferred
    Embodiment of the invention with reference to the accompanying drawings. It shows
    1 shows a part of an armchair of a chairlift in side view,
    2 is a detail of Fig. 1 in an oblique view on an enlarged scale,
    Fig. 3 is a side view of the device in the locked state and
    Fig. 4 is a view corresponding to Fig. 3 in the dissolved state of the device.
    In Fig. 1, a frame part 1 is shown, which is either attached to the frame of a chairlift or itself forms part of the frame.
    On the frame part 1, a safety bar 2 is pivotally mounted, wherein the safety bar 2 has a mounting plate 3 which is mounted on the frame part 1 via a hinge 4.
    On the frame part 1, a bracket 5 is fixed, for example screwed by means of screws 10 on the frame part 1. The bracket 5 has a spring arm 6, at the end of a projection 7 is arranged. The projection 7 has two sliding surfaces 8 and 9, which are substantially A-shaped, but asymmetrical, ie in
    Shape of a sloping "A", are aligned. On the mounting plate 3, a further projection 11 is arranged, which in turn has two sliding surfaces 12 and 13, which are also arranged in the form of an inclined "A".
    In the position shown in Figs. 1, 2 and 3, the safety bar 2 is in the closed end position, in which it extends across the legs of the passengers. In this position, the projection 11 of the mounting plate 3 is located at the free end of the bracket 5 adjacent sliding surface 8 at.
    The spring arm 6 of the bracket 5 has in the illustrated embodiment, an approximately I-shaped profile, whereby this can apply a large bending resistance torque at a low weight. Preferably, the bracket 5 is made of plastic, but may also consist of spring steel or a combination of these or other materials.
    Preferably, the resilient bracket 5 is slightly biased in the position shown in FIGS. 1 to 3, so that it presses the safety bar 2 in the closed end position down. He may also be tension-free in this position, since the safety bar 2 is held positively.
    If the safety bar 2 to be opened in the direction of arrow 14, the resilient bracket 5 must be pushed away in the direction of arrow 15 against its spring force, the tip of the projection 11 slides over the sliding surface 8 until the projections 7, 11 were moved past each other , as shown in Fig. 4.
    From this moment on, the safety bar 2 can be moved unhindered upwards into the other open end position.
    When the safety bar 2 is to be closed again, it is first moved to the position shown in Fig. 4 until the projection 11 comes to the mounting plate 3 in abutment against the sliding surface 9 on the resilient bracket 5. From this moment, the spring force of the resilient yoke 5 must be overcome for a further closing movement until the safety bar 2 or its mounting plate 3 has again reached the position shown in FIGS. 1 to 3.
    By the force that must be applied during closing on or through the safety bar 2, so that the spring force of the bracket 5 is overcome, accidental closing of the safety bar 2 can be prevented, so that it can be freely moved up again and it to no operational disturbances due to lack of clearances at the station passage of the armchair can come.
    The device according to the invention is particularly preferably used in armchairs of chairlifts which have a spring, for example a tension spring, which automatically moves the safety bar 2 into the open position in order to compensate for the weight of the safety bar 2. According to the invention, this spring force may be greater than it would be necessary to compensate for the weight of the safety bar 2, since the safety bar 2 is actively held by the bracket 5 in the closed end position.
    This makes it possible, in a further consequence, to build up a defined force system in which the outer forces, for example wind forces, vibrations and the like acting on the armchair and the safety bar 2, are counteracted overcompensated, whereby unstable equilibria of forces can be avoided which lead to movements or positions The protective device can lead, some of which may be undesirable, sometimes even irregular.
    By the device according to the invention can further be set a relatively accurate holding force of the safety bar 2, which must be overcome in order to open the safety bar 2, wherein the safety bar 2 then automatically supported by the mentioned spring force automatically opens automatically.
    In place of in the. Figures shown resilient yoke 5 also other measures can be taken so that at least one of the two projections 7, 11 can yield resiliently. It would be conceivable, for example, a lever with a projection, wherein the lever against the force of a tension or compression spring or torsion spring, a rubber-metal sleeve, a polymer element or the like, is pivotable. It would also be conceivable, for example, to hold a ball or a pin displaceable against a spring in a bore.
    In the drawings, a further projection 11a is optionally located next to the projection 11 on the mounting plate 3, which forms a second locking step for the safety bar 2. The safety bar 2 is thus locked when closing first by the projection 11 and subsequently by the projection 11 a finally in its final position. It is understood that the second projection 11a need not be present or on the bracket 5, a further projection could be present.
    In summary, an embodiment of the invention can be described as follows:
    A device for locking a pivoting protective device, such as a safety bar 2 or a weatherproof hood, a chair for a chairlift, has cooperating projections 7, 11, 11 a, one with a frame of the chair and the other with the
    Protective device is connected. At least one of the projections 7 is resiliently mounted and on the projections 7, 11, 11 a are sliding surfaces 8, 9; 12, 13 are arranged, which cause after application of a defined force on the safety bar 2, a deformation of the resilient bracket 5 and allow sliding past the projections 7, 11, 11a to each other in both directions.
