Definitions
- 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.
- 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.
- Safety bars or weather protection hoods when they are in the fully open or fully closed end position, must be kept stable in this position, which can be done on the one hand by gravity and the other supported by springs or locking mechanisms.
- the invention is therefore an object of the invention to provide a device with which protective devices are securely held in a particular position and yet under
- Protrusions is resiliently mounted and that are arranged on the projections sliding surfaces which a sliding past the Allow projections in both directions.
- the force of the one projection can be adjusted relatively accurately, which is required to move the safety bar from its closed end position to the open position.
- the safety bar is biased by a spring, for example a tension spring in the open position, which is the opening of the safety bar
- 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 only at a
- the spring force of the projection must exert a holding force, which a total force of about 50 to 60 N (measured at the front of
- the device according to the invention also prevents the safety bar from unintentionally falling into the end position and being held therein. Namely, if the safety bar by vibrations or other forces or, for example, the automatic closure of the weather protection hood (in empty vehicles), which moves the safety bar, moves toward the lower end position, then prevents the device or the abutting projections the achievement of the fully closed end position, since the spring force of a resilient projection is not overcome.
- the safety bar can thereby automatically reopen or create on the closed weather protection hood and
- Fig. 1 shows a part of an armchair of a chairlift in
- Fig. 2 shows a detail of Fig. 1 in an oblique view in
- Fig. 3 is a side view of the device in blocked
- Fig. 4 is a view corresponding to Fig. 3 in the dissolved state of the device.
- a frame part 1 is shown, which is either attached to the frame of a chairlift or itself forms part of the frame.
- 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.
- 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 the form of an inclined "A" aligned.
- the safety bar 2 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
- the bracket 5 is made of plastic, but can also be made of spring steel or a
- the resilient bracket 5 is slightly biased in the position shown in FIGS. 1 to 3, so that he
- Safety bar 2 pushes down into the closed end position. He may also be tension-free in this position, since the safety bar 2 is held positively.
- the safety bar 2 can be moved unhindered upwards into the other open end position.
- 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 bracket 5 must be overcome for a further closing movement until the safety bar 2 or
- the device according to the invention is particularly preferably used in armchairs of chairlifts, which are a spring,
- Safety bar 2 automatically moved to the open position to compensate for the weight of the safety bar 2.
- 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.
- Safety bar 2 acting, external forces, such as wind forces, vibrations and the like, overcompensated
- 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 in a row
- 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.
- a further projection IIa 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 IIa finally in its final position. It is understood that the second projection IIa need not be present or on the bracket 5, a further projection could be present.
- Protective device such as a safety bar 2 or a weatherproof hood, a chair for a chairlift, has cooperating projections 7, 11, IIa, one of which with a frame of the chair and the other with the
- At least one of the projections 7 is resiliently mounted and on the projections 7, 11, IIa Sliding surfaces 8, 9; 12, 13 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, IIa to each other in both directions.
