摘要： A lightweight caster is described that is resistant to ingress of debris into a caster bearing. The caster has a monolithic fork having an annular wheel-supporting portion and a chair-supporting portion. The wheel-supporting portion has a pass-through aperture for receiving a retainer. A rotational bearing is supported on the wheel-supporting portion, which supports a wheel rim such that the wheel rotates in the vertical plane. The rim has a pass-through aperture aligned with the pass-through aperture of the fork, and a ring at an inside edge of the bearing to retain the bearing between the rim and the fork and to inhibit debris from contacting the bearing. A retainer retains the rim on the fork and has an aperture aligned with the fork pass-through aperture. The retainer also has a bearing-retaining portion at an outside edge of the bearing to retain the bearing and to inhibit debris from migrating inwardly.

摘要： The invention relates a lockable caster wheel. The lockable caster wheel can be widely used in shopping carts, luggage carts, strollers, turnover carts, stretcher cars and many other trolleys. The controlling mechanism of the lockable caster wheel comprises a controller which comprises a signal receiving device and a locking device which is controlled by the controller. The locking mechanism further comprises a revolving damper which comprises a shell having a restricting structure and a damping wheel located inside the shell. The shell, through its restricting structure, separates from or connects with the locking device to form unlocked or locked states. The damping wheel connects with the wheel assembly. The caster wheel uses a damper. Beyond the allowed area of use, the trolleys can be slowly pushed for a few of meters because of the damper effect, but it will not suddenly stop completely. Therefore it will not present danger to the users. It can also prevent the casters from being damaged by a forceful push when they are locked.
摘要翻译： 本发明涉及可锁定脚轮。 可锁定脚轮可广泛用于购物车，行李车，婴儿推车，周转车，担架车和许多其他手推车。 可锁定脚轮的控制机构包括控制器，该控制器包括由控制器控制的信号接收装置和锁定装置。 锁定机构还包括一个旋转阻尼器，它包括具有限制结构的壳体和位于壳体内部的阻尼轮。 壳体通过其限制结构与锁定装置分离或连接以形成解锁或锁定状态。 阻尼轮与车轮组件连接。 脚轮使用阻尼器。 超过允许的使用范围，手推车可以缓慢推动几米，因为阻尼效应，但不会完全停止。 所以不会给用户带来危险。 它也可以防止脚轮在锁定时被强力推动而损坏。

摘要： A caster includes a yoke for retaining a wheel, a bearing housing connected to the yoke and a replaceable shielded bearing occupying the bearing housing. The inner wall of the bearing housing is provided with a groove into which a retaining ring may be inserted to prevent the shielded bearing from escaping. A caster mounting assembly having a connecting member which passes through a central opening of the shielded bearing is configured to connect the yoke and the bearing housing to a rollable article, such as chair or table. In the event that the shielded bearing needs to be replaced, the caster may be disassembled, the retaining ring removed from the groove, a new shielded bearing substituted for the old shield bearing, the retaining ring replaced in the groove, and the caster reassembled.

摘要： A scarf hides the upper portion of a made bed from view. The scarf includes a portion of material having a length and a width, opposite first and second ends and opposite top and bottom edges. The length of the scarf is sufficient to cover pillows placed on a made bed of standard size, with the opposite first and second ends reaching opposite first and second edges of the bed. The width of the scarf is sufficient so that its top edge hides the top edge of a pillow on the made bed, and the bottom edge hides the bottom edge of the pillow on the made bed. The scarf may be used to cover up the top edge of a bed sheet, blanket or bedspread on a made bed so as to hide said top edge of the bed sheet, blanket or bedspread.

摘要： A castor includes a main body, two rollers, a plurality of rolls, two retaining members, and two covers. Thus, the rolls are rotatably mounted between the main body and the respective roller, so that each of the rollers is rotatable on the main body smoothly. In addition, the rolls and the rollers are made of the same material to reduce the friction between the rolls and the rollers during rotation of the castor, so that the rolls and the rollers are not easily worn out during a long-term utilization. Further, the rollers are covered by the covers so that only the through hole of the main body is exposed outwardly from the covers and the rollers, thereby enhancing the aesthetic quality of the castor.

摘要： A caster has a stationary hub with a bearing between the hub and a floor engaging wheel ring which allows the wheel ring to rotate relative to the hub. Torsional elastomeric elements mount the hub between spaced support arms radially inward of the bearing and are positioned eccentrically relative to the axis of rotation of the wheel ring so as to suspend the hub resiliently between the arms. In an alternate embodiment, the hub is cantilevered from a single support arm.

摘要： A carriage for a mobile storage system, including a frame having an inverted U-shaped cross section, including two downwardly depending sides extending the length of the frame. A drive shaft is journaled to the frame and rotated by a prime mover. A drive wheel affixed to the drive shaft rotates with it. A driven shaft, journaled to the frame and oriented parallel to the drive shaft, carries a driven wheel within the frame, for moving the carriage along the rails. A drive chain or belt is provided for transmitting power from the drive wheel, via the driven shaft, to the driven wheel. The driven shaft is journaled to the frame by means of flangette bearings, each bearing affixed to a respective offset mounting bracket. Each bracket is affixed to one of the frame sides, there being insufficient clearance between the driven wheel and the frame sides for the placement of the flangette bearings. The tension of the drive chain or belt is adjusted by a tensioning bracket slidably connected to the frame, permitting sliding movement of the tensioning bracket transverse to the drive chain or belt. A tensioning block is affixed to the bracket, and a bolt is threaded to the frame for sliding the tensioning block toward and away from the drive chain or belt.
