摘要： A self-locking slider mechanism for holding telescoping relatively-movable inner and outer tubular members in adjusted lengthwise position and which requires a greater force manually applied lengthwise of the members to decrease the over-all length of the members than to increase the over-all length thereof. The members can be used as a stand to provide a load-carrying capacity for the stand while still enabling adjustment of stand height with minimal effort. The slider mechanism has a body member attached to one tubular member and having an internal recess extending lengthwise thereof and opening to one side of the body with an inclined ramp plate mounted within the recess and associated with a ramp member movable therealong and which has a friction member engageable with the other tubular member. A plurality of compression springs are associated with the ramp plate and the ramp member and the ramp plate is inclined whereby a force tending to lower the height of the stand as by a load carried by the stand is reacted against relatively stiff compression springs associated with the ramp plate. A force tending to increase the over-all length of the tubular members is resisted by a lesser spring force acting on the ramp member and the ramp member moves downwardly along the inclined ramp plate to reduce the pressure applied by the friction member.
摘要翻译： 一种自锁滑动器机构，用于保持可调节的相对移动的内部和外部管状构件在调节的纵向位置，并且需要更大的力来手动地施加构件的纵向以减少构件的整体长度，而不是增加全部 长度。 这些构件可以用作支架，以便为支架提供承载能力，同时仍然能够以最小的努力调整支架高度。 滑动器机构具有本体部件，该主体部件附接到一个管状部件，并且具有沿其长度方向延伸的内部凹部，并且在主体的一侧开口，并具有安装在凹部内的倾斜斜面板，并与可沿其移动的斜面部件相关联， 构件可与另一管状构件接合。 多个压缩弹簧与斜面板和斜面构件相关联，并且斜面板倾斜，由此通过支架承载的负载倾向于降低支架的高度的力与相对较大的压缩弹簧 斜坡板。 趋向于增加管状构件的全部长度的力被作用在斜坡构件上的较小弹簧力抵抗，并且斜坡构件沿着倾斜坡道向下移动以减小由摩擦构件施加的压力。

摘要： A portable shell of a lightweight construction usable as a room divider, display panel, or acoustical or visual enclosure detachably connectable to the framework for mounting in either a support position or a storage position. The leg structure includes a pair of legs each having a pivotally-mounted foot movable between an operative position or a storage position. Additionally, the shell has a canopy panel hinged to one end thereof for extending the height of the shell and the legs can be attached at different positions on the framework for providing different effective shell heights.
