    • A high strength, engineered collapsible support has separate shear bearing surfaces and pivot elements which permit efficient manufacture and higher strength. Unitary brace attachment is achieved with designs which can be molded and yet both efficiently manufactured and made acceptably strong such that heavy items such as performance or commercial speakers can be mounted stably. An extendible sleeve permits adjustment; a semiautomatic as well as manual clutch assembly permits quick securement of the top mast to the tripod; compression rings allow a secure fitting to be established between various pieces; leg upper end caps allow the legs of the tripod to be coupled to the main mast of the tripod; an end plug can serve to reduce the number of parts necessary to couple the various leg braces to the bottom of the main mast. Strength is achieved through multiple shear surfaces located at a distance from a pivot retention element and with parallel braces.
    • 高强度,可设计的可折叠支架具有独立的剪切支承表面和枢轴元件,可以有效地制造和提高强度。 通过可以模制的设计实现单体支撑附件,并且可以有效地制造和制造可接受的强度,使得可以稳定地安装诸如性能的商品或商业扬声器等重物品。 可扩展的套筒允许调整; 半自动和手动离合器组件允许将顶部桅杆快速固定到三脚架上; 压缩环允许在各个部件之间建立牢固的配件; 腿上端帽允许三脚架的腿连接到三脚架的主桅杆; 端塞可以用于减少将各种支腿连接到主桅杆底部所需的部件数量。 强度通过位于与枢转保持元件一定距离并具有平行支架的多个剪切表面实现。

    • In at least one embodiment, an apparatus (1) that comprises a compression sleeve element (2) established at least partially around portions of a first elongated member (6) that telescopes from a larger elongated member (8) in which it may nest. A relative motion obstruction element (4) may disallow only certain types of motion, e.g., rotational and axial, of the compression sleeve element relative to the elongated members around which it may be at least partially established. As it may be the compression enhancement element (3) —which may be used to generate a retaining compression force element—that prevents perpendicular displacement of the compression sleeve element, deactivation and effective disengagement of the compression enhancement element may allow for a quick removal of the compression sleeve element without requiring that it be slid off an end of either elongated member.
    • 在至少一个实施例中,一种装置(1)包括压缩套筒元件(2),该压缩套筒元件(2)至少部分地围绕从其可嵌套的较大细长构件(8)伸缩的第一细长构件(6)的部分。 相对运动阻塞元件(4)可以不允许压缩套筒元件相对于可以至少部分地建立的细长构件的某些类型的运动,例如旋转和轴向运动。 由于压缩增强元件(3)可以被用于产生保持压缩力元件,其可防止压缩套筒元件的垂直位移,所以压缩增强元件的失活和有效的分离可允许快速移除 压缩套筒元件,而不需要从一个细长构件的端部滑动。

    • A system for conveniently storing a wheel, tire or similar object. The invention allows a user to easily insert such an object into a support stand and establish a three point support of the object. Furthermore, the system has an actuation feature that allows a support stand to be easily and compactly configured for storage and shipment. The system uses a rotating support surface to establish contact with a wheel, tire or other similar object. In this fashion, a normal force can be exerted against the object while the support surface is free to turn. This allows an object with a rough surface area to be positioned by the force while not allowing the rough surface area to effect such positioning. A mechanism accommodates tires of different sizes, thereby allowing tires to be positioned on support settings unique to each sized tire. A self adjusting feature allows the movement arm to move in response to the tire size, thereby establishing the appropriate settings. A rotating support is disclosed that provides greater flexibility to a support stand in interfacing with tires of rough surface areas by preventing those surface areas from interfering with the support establishment process.
    • 一种用于方便地存放车轮,轮胎或类似物体的系统。 本发明允许用户将这样的物体容易地插入到支撑架中并建立物体的三点支撑。 此外,该系统具有致动特征,其允许支撑架容易且紧凑地构造用于存储和运输。 系统使用旋转的支撑表面来建立与轮,轮胎或其它类似物体的接触。 以这种方式,当支撑表面自由转动时,能够对对象施加法向力。 这允许具有粗糙表面积的物体通过力定位,而不允许粗糙表面区域实现这种定位。 机构适应不同尺寸的轮胎,从而允许轮胎定位在每个尺寸轮胎独特的支撑设置上。 自调整功能允许移动臂响应于轮胎尺寸移动,从而建立适当的设置。 公开了一种旋转支撑件,其通过防止这些表面区域干扰支撑建立过程而使得支撑台与粗糙表面区域的轮胎接合提供更大的灵活性。
