    • Such invention concerns a ladder (1) of the transportable type comprising: A frame (2, 3, 4) suitable for allowing the arrangement of one or more supporting surfaces (6) through which a user can reach one or more different heights from the ground; At least a wheel (19) forming a support point to the ground, said wheel being suitable for allowing the movement of the ladder; A braking device (5, 10, 15, 20) to lock the wheels. According to the invention, such braking device comprises a braking body (5') cooperating with said wheel, said wheel being arranged in such a manner to result movable between an extended position, wherein it emerges respect to the braking body, contacting in use the ground, and a retracted position wherein, in use, the braking body contacts the ground exerting a braking action and wherein, further, pushing means (10) are comprised and configured in such a manner to maintain said wheel in said extended position for force values that act on it, in the direction of movement towards the retracted position, that are below to a predetermined threshold value and allow a movement of the wheel towards the retracted position, when reached or exceeded this threshold force value, in such a manner that when the wheel is retracting, the braking body moves to contact the ground.
    • 本发明涉及一种可移动类型的梯子(1),包括:框架(2,3,4),其适于允许布置一个或多个支撑表面(6),用户可通过该支撑表面 从地面到达一个或多个不同的高度; 至少一个轮子(19)形成对地面的支撑点,所述轮子适合于允许梯子的移动; 制动装置(5,10,15,20)锁定车轮。 根据本发明,这种制动装置包括与所述车轮配合的制动体(5'),所述车轮以这样的方式布置,使得所述制动体在相对于制动体出现的延伸位置和在使用中接触 地面和缩回位置,其中在使用中,制动体接触施加制动作用的地面,并且其中推力装置(10)被构造和构造成使得所述车轮保持在所述伸展位置以获得力值 在朝向缩回位置的运动方向上作用于其上的,低于预定阈值的力,并且当达到或超过该阈值力值时,允许车轮朝缩回位置移动,使得当 车轮正在收缩,制动体移动到接触地面。

    • A wheel and tire assembly for recreational vehicles, such as mountainboards, motorized carts and pedaled carts is provided. The tire comprises a tire made of substantially inelastic material that will not stretch under a load. Thus, the tire will flatten under a load to provide a high level of traction on soft and irregular surfaces, as well as on hard and flat surfaces. The tire includes protrusions on its inner diameter surface for securely engaging the wheel. The wheel includes a rim that supports the tire and includes protrusions for engaging the protrusions of the tire in an interdigitating manner. The interdigitating engagement of the protrusions on the tire with the protrusions on the wheel prevents slippage and rotation of the tire relative to the wheel. The wheel also includes support flanges that extend radially inward from the rim in order to protect the tire from damage as the tire deforms under a load.
    • 提供了一种用于休闲车辆的车轮和轮胎组件,例如山地车,电动车和踏板车。 轮胎包括由基本上非弹性材料制成的轮胎,其不会在负载下拉伸。 因此,轮胎将在负载下变平,以在柔软和不规则的表面上以及在硬和平的表面上提供高水​​平的牵引力。 轮胎在其内径表面上包括突起,用于牢固地接合车轮。 车轮包括支撑轮胎的轮辋,并且包括用于以交错方式接合轮胎的突起的突起。 轮胎上的突起与轮上的突起的叉指接合防止轮胎相对于车轮的滑动和旋转。 车轮还包括从轮辋径向向内延伸的支撑凸缘,以便在轮胎在负载下变形时保护轮胎免受损坏。
