    • Elevator guide shoe for guiding an elevator car along guide rails in an elevator shaft, said guide shoe comprising a supporting frame (2) attached to the elevator car (1) and guides (4) resting against a guide rail (3). According to the invention, the guide shoe comprises an intermediate frame (5), to which the guides (4) are attached. In addition, the supporting frame (2) and the intermediate frame (5) are provided with permanent magnet bars (6a, 6b, 7a, 7b, 8a, 8b) arranged to maintain a horizontal distance between the supporting frame and the intermediate frame. Moreover, the guide shoe comprises vertical suspension (9) between the supporting frame and the intermediate frame to damp the propagation of sound in the structures.
    • 电梯导板,用于沿电梯井道中的导轨引导电梯轿厢,所述导靴包括附接到电梯轿厢(1)的支撑架(2)和靠在导轨(3)上的导轨(4)。 根据本发明,导靴包括中间框架(5),引导件(4)附接到该中间框架。 此外,支撑框架(2)和中间框架(5)设置有用于保持支撑框架和中间框架之间的水平距离的永久磁棒(6a,6b,7a,7b,8a,8b)。 此外,导靴包括在支撑框架和中间框架之间的垂直悬架(9),以阻尼声音在结构中的传播。

    • An elevator without counterweight may Include an elevator car suspended by a hoisting rope, a traction sheave operatively connected to the elevator car by the hoisting rope, and a brake structure configured to engage with the traction sheave in a braking operation in an upward motion and a downward motion of the elevator car. The brake structure may include first and second brake elements. The first brake element may include a surface engageable with the traction sheave, and first contact and sliding surfaces. The second brake element may include second contact and sliding surfaces. The first sliding surface may slide along the second sliding surface relative to the second brake element when the elevator car moves with the upward motion. The second contact surface may contact the first contact surface to stop a sliding motion of the first brake element when the elevator car moves with the downward motion.
    • 没有配重的电梯可以包括由提升绳索悬挂的电梯轿厢,通过提升绳可操作地连接到电梯轿厢的牵引滑轮,以及构造成在向上运动的制动操作中与牵引滑轮接合的制动结构, 电梯轿厢向下运动。 制动结构可以包括第一和第二制动元件。 第一制动元件可以包括可与牵引滑轮接合的表面,以及第一接触和滑动表面。 第二制动元件可以包括第二接触和滑动表面。 当电梯轿厢以向上运动移动时,第一滑动表面可相对于第二制动元件沿着第二滑动表面滑动。 当电梯轿厢以向下运动移动时,第二接触表面可接触第一接触表面以停止第一制动元件的滑动运动。
