    • Disclosed is an expansible fastening device (10) for placement in a hole preformed in a base member for use in attaching a component part to the base using a conventional nut (24) and bolt (26). The fastening device includes a fastener body (12) having two body sections (28a, and 28b). The body sections when positioned together form a central cavity (30) within the fastener body which encloses and retains the nut and a wedge (14). Each longitudinal section includes a fin (16) which extends longitudinally and projects radially outward from the central region of each body section. Further, each body section includes primary and secondary teeth (18 and 20) which extend circumferentially about the outer surface of the sections. In operation the bolt is engaged with the nut and rotated, pushing the wedge from the fastening device. As the wedge is driven away from the nut, the teeth and fins are driven into the base member.
    • 公开了一种可膨胀的紧固装置(10),用于放置在预先形成在基件中的孔中,用于使用常规螺母(24)和螺栓(26)将部件附接到基座。 紧固装置包括具有两个主体部分(28a和28b)的紧固件主体(12)。 定位在一起的主体部分形成在紧固件主体内的中心腔(30),其包围并保持螺母和楔形件(14)。 每个纵向部分包括一个纵向延伸并从每个主体部分的中心区域径向向外突出的翅片(16)。 此外,每个主体部分包括围绕部分的外表面周向延伸的主齿和副齿(18和20)。 在操作中,螺栓与螺母接合并旋转,从紧固装置推动楔形件。 当楔形件从螺母驱动时,齿和翅片被驱动到基座构件中。

    • A playground apparatus (10) for children to slide across while hanging by their hands is disclosed. The apparatus includes a support structure (12, 16, and 20) holding multiple rails (18), preferably five, horizontally above the ground and above the heads of the children. The rails are generally parallel one to another and include gentle curves along their length. Handhold assemblies (22) are slidably coupled to each of the rails and include two grips (40) on each assembly for users' hands. The grips are disposed below the rails and the handhold assemblies include partitions (46) between the rails and the grips to protect the children's hands from the rails. The handhold assemblies include channels (44) in which the rails are received and allowed to slide. The channels are wider in their middle portions than at their ends to accommodate the curves in the rails. Platforms (26) are constructed at the ends of the support structure to provide a place for the children to stand when reaching the handhold assemblies.
    • 公开了一种用于儿童在双手悬挂的情况下滑过的操场设备(10)。 该装置包括一个支撑结构(12,16和20),该支撑结构保持多个轨道(18),优选地五个在水平地上方和儿童的头部上方。 导轨大致相互平行,并且包括沿其长度的平缓曲线。 手柄组件(22)可滑动地联接到每个轨道并且在用于用户的手的每个组件上包括两个把手(40)。 把手设置在轨道下方,并且手持组件包括在轨道和把手之间的隔板(46),以保护儿童的手不受轨道的影响。 手柄组件包括通道(44),轨道被容纳在其中并被允许滑动。 通道在其中间部分比在其端部更宽以适应轨道中的曲线。 平台(26)在支撑结构的端部构造,以便在到达手持组件时为孩子们提供一个放置位置。

    • In accordance with the present invention, a playground carriage (10) is provided for moving people (100) from one play area to another. The playground carriage comprises a rotatable support pipe (12) having a first end (14) and a second end (16). The support pipe extends between a first vertical column (18) and a second vertical column (20). A manually-operated crank extends between the first vertical column and a third vertical column (48). The first end of the crank is coupled to the first end of the support pipe so that manually turning the crank rotates the support pipe. A carriage (28) for carrying people is mounted to the support pipe. The carriage is advanced along the support pipe by a carrier assembly (102). The carrier assembly comprises a carrier (30) which propels the carriage and a brake (104) which is capable of bringing the carriage to a stop.
    • 根据本发明,提供了一个用于将人(100)从一个游戏区域移动到另一个游乐区的操纵台架(10)。 游乐场托架包括具有第一端(14)和第二端(16)的可旋转支撑管(12)。 支撑管在第一垂直柱(18)和第二垂直柱(20)之间延伸。 手动操作的曲柄在第一垂直柱和第三垂直柱(48)之间延伸。 曲柄的第一端连接到支撑管的第一端,从而手动转动曲柄使支撑管旋转。 用于携带人的托架(28)安装到支撑管上。 托架通过托架组件(102)沿着支撑管推进。 托架组件包括推动滑架的托架(30)和能够使托架停止的制动器(104)。

The first end of the crank is coupled to the first end of the support pipe so that manually turning the crank rotates the support pipe. A carriage (28) for carrying people is mounted to the support pipe. The carriage is advanced along the support pipe by a carrier (30). The carrier comprises a set of wheels (31) oriented along an outer surface (34) of the support pipe so that the wheels follow a helical, thread-like path along the support pipe and, thus, propel the carrier along the support pipe. A plurality of handrails (36) extend downwardly from the carrier and attach to a platform (37) so that the platform is suspended below the carrier. A protective housing (88) encapsulates the carrier. A guide rail (43) is located immediately below the platform of the carriage and extends parallel to the support pipe between the first vertical column and the second vertical column. In addition, a guide (38) is attached to a lower surface (35) of the platform and engages the guide rail in order to prevent the carriage from swinging excessively as it moves along the support pipe.
    • 根据本发明,提供了一个用于将人(100)从一个游戏区域移动到另一个游乐区的操纵台架(10)。 游乐场托架包括具有第一端(14)和第二端(16)的可旋转支撑管(12)。 支撑管在第一垂直柱(18)和第二垂直柱(20)之间延伸。 还包括具有第一端(24)和第二端(26)的手动操作的曲柄(22)。 手动曲柄在第一垂直柱和第三垂直柱(48)之间延伸。 曲柄的第一端连接到支撑管的第一端,从而手动转动曲柄使支撑管旋转。 用于携带人的托架(28)安装到支撑管上。 托架通过托架(30)沿着支撑管推进。 载体包括沿着支撑管的外表面(34)定向的一组轮(31),使得轮沿着支撑管沿着螺旋状的螺纹状路径,并因此沿着支撑管推动载体。 多个扶手(36)从托架向下延伸并且附接到平台(37),使得平台悬挂在托架下方。 保护壳体(88)封装载体。 导轨(43)位于滑架的平台的正下方,并平行于第一垂直柱和第二垂直柱之间的支撑管延伸。 此外,引导件(38)附接到平台的下表面(35)并且接合导轨,以便防止滑架在沿着支撑管移动时过度地摆动。
