  • Patent number: 11554935
    Abstract: An elevator car has a balustrade arranged on a roof of the elevator car, wherein the balustrade includes posts, that are attached on a horizontal upper side of the roof, and post-connecting crossmembers. For each post, a docking element is arranged on the upper side of the roof, and the post can be docked on the docking element. The docking element has form-fitting elements in the form of fingers for accommodating the post in a form-fitting manner and the post has slots or apertures, that are complementary to the fingers, the fingers engaging in the slots or the apertures. The docking element is a flattened component made up of two stacked plates and is screwed to the roof. The balustrade is secured by obliquely running supporting profiles extending between the handrail and the roof.

  • Patent number: 9695011
    Abstract: An elevator car guided at guide rails has a safety brake exerting a braking force on the guide rails in the event of non-compliance of a safety criterion. A housing of the safety brake has a wedge-shaped opening into which the guide rail is introduced, a brake body in the opening between a surface of the housing bounding the opening and a guide surface of the guide rail, an activating mechanism for transmitting an activation force to the brake body to press the brake body against the bounding surface and the guide surface, and a release mechanism connected indirectly or directly with the brake body for keeping the brake body in a rest position against the activation force. The release mechanism includes an articulated arm movable into an extended position for holding the brake body in the rest position and into a folded position for releasing the activation force.

  • Patent number: 7905328
    Abstract: A brake device of an elevator car with a brake unit that is mounted on the elevator car. The brake drive includes a flexible tension member that passes around two tension-members reversing-sheaves. One end of the tension members extends parallel to the travel path of the elevator car and is coupled to an actuating element of the brake unit, and thereby also to the elevator car, so that in normal operation the tension member moves synchronously with the elevator car. A blocking device, at least on overspeed of the elevator car, brakes the tension member, as a consequence of which the tension member, via the actuating element, activates the brake unit. A monitoring device detects failure of the coupling between the tension member and the elevator car.

  • Patent number: 7475756
    Abstract: In relation with this mechanism for stopping an elevator car is, for the monitoring of the speed of the elevator car, an overspeed governor provided which works based on the swing lever principle, whereby the movement of the elevator car will be transferred by means of a governor rope to the overspeed governor. The governor rope extends itself over the entire shaft height and will be returned at the lower shaft end by means of a deflection sheave and stretched by means of counterweight as well as guided at the upper shaft end over a pulley of the overspeed governor. The ends of the governor rope are fastened on a release mechanics arranged on the elevator car and such release mechanics operates in an emergency a safety gear arranged on the elevator car. With the overspeed of the elevator car a rope brake is released upwards.

  • Patent number: 7128189
    Abstract: A tripping device for engaging an elevator lift cage safety brake has actuating levers arranged at a rotary axle for engaging safety brake wedges of the safety braking device. Each actuating lever has a longitudinal slot matched to the diameter of the rotary axle, wherein the actuating lever is freely movable in the direction of the rotary axle and in the direction of the length of the actuating lever. A torsion spring fixes the actuating lever about the rotary axle. One spring end presses the actuating lever downwardly, wherein the movement of the actuating lever is limited by a lower abutment. The other spring end is detachably connected to a support. An upper abutment limits the movement of the actuating lever upwardly. The lower abutment and the upper abutment are each held at a respective end of a T-shaped shackle, wherein the shackle is fixedly connected to the rotary axle.

  • Patent number: 6823969
    Abstract: A braking device acts on a guide rail and consists of a housing that is arranged at an elevator car yoke and serves as a support for spring packets and/or for adjusting packets. The housing also serves as a support and guide for chock guide elements that in turn retain and guide brake chocks with brake linings. Pushrods engage at one end at the brake chocks, and at the other end are pivotably connected to an actuating fork. Upon braking of the elevator car, the actuating fork is moved at the pushrod end in the direction of the braking device. The guided brake chocks with the brake linings slide in the braking device. At the same time the brake linings are moved at the guide leg of the guide rail. The brake chocks are moved in the braking device and the spring and adjusting packets are stressed, whereby a braking force for stopping an elevator car or a counterweight is generated.

  • Patent number: 6719101
    Abstract: A safety brake for braking a load receiving portion of an elevator has at least one brake wedge that penetrates a gap between a resiliently supported pressure body and a guide rail for the load receiving portion of the elevator and thereby generates a braking force. A stroke limiting device limits the penetration stroke of the brake wedge and controls the braking force in dependence on the retardation value of the load receiving portion of the elevator.
