摘要： A locking device for protecting the contents of a container from theft includes an extension member having an adjustable length and a lock for inhibiting adjustment of the extension member's length when the lock is engaged. To secure the contents of a container from theft, the locking device is installed between two opposing surfaces, such as between two vertical wall surfaces, with the extension member extending across the container door with the door in its closed position. The locking device is installed by simply inserting each end of the extension member into suitable cavities formed in the opposing surfaces, or in brackets attached to the opposing surfaces, adjusting the length of the extension member as necessary. Thereafter, the lock can be engaged to prevent adjustment of the extension member's length, and thereby prevent removal of the ends of the extension member from the surface openings. With the locking device so installed, and the extension member extending across and perhaps contacting a portion of the container door, the container door cannot be opened by prying or otherwise without first removing the locking device. Because the locking device cannot be removed without adjusting the length of the extension member, which in turn requires possession of the correct key or combination to disengage the lock, unauthorized access to the container contents is prevented.

摘要翻译： 用于保护容器的内容物免于盗窃的锁定装置包括具有可调节长度的延伸构件和用于在锁定接合时阻止延伸构件长度的调节的锁。 为了将容器的内容物从盗窃中固定，锁定装置安装在两个相对的表面之间，例如在两个垂直的墙壁表面之间，延伸构件延伸穿过容器门，门处于关闭位置。 锁定装置通过简单地将延伸构件的每个端部插入形成在相对表面中的合适的空腔中，或者在附接到相对表面的托架中来安装，根据需要调整延伸构件的长度。 此后，锁可以被接合以防止延伸构件的长度的调节，从而防止延伸构件的端部从表面开口移除。 通过如此安装锁定装置，并且延伸构件延伸穿过并且可能接触容器门的一部分，则容器门不能通过撬动或以其他方式打开而不首先移除锁定装置。 因为锁定装置不能在不调整延伸构件的长度的情况下被移除，而延伸构件又需要拥有正确的钥匙或组合以使锁脱开，所以防止对容器内容物的非法访问。

摘要： A shovelling tool has a flexible portion at the base of the handle that helps prevent the risk of injury when shovelling by absorbing the initial shock when digging or by adjusting gradually to a different load when shovelling. This tool, which is preferably telescopic, is particularly useful for removing snow and ice.

摘要： A van wall brace for reinforcing a truncated pillar of a van wall which has been cut in order to accommodate a retrofitted window. The van wall brace connects to the severed end of truncated pillar and is tied into adjacent intact pillars so as to lend structural integrity to the truncated pillar, thereby restoring strength to the van wall. The van wall brace is preferred to be formed of a single piece of heavy gauge sheet metal stock of elongate shape. Each end of the sheet metal stock is stamped with a predetermined reciprocal pillar contour or contours for engaging the intact pillars located on either side of the truncated pillar or pillars. The sheet steel stock is further stamped between the ends thereof so as to provide another predetermined reciprocal pillar contour or contours for engaging each truncated pillar or pillars. The stamping location of each reciprocal pillar contour is predetermined so that the completed van wall brace will engage each of the aforesaid pillars of the particular van that has been modified. Between each of the aforesaid reciprocal pillar contours the sheet metal stock is preferred to be stamped to include edge flanges, thereby providing high strength against bending. The van wall brace is secured to the aforesaid pillars either by a standard fastener or by welding.

摘要： An apparatus for passive extension and flexion of at least one finger of a patient with an upper arm unit, a lower arm unit, and at least one connective line. The apparatus is configured such that elbow extension of the patient promotes finger flexion. This is accomplished by taking advantage of the geometry of the arm, where the distance from a point on the patient's humeral area to the patient's fingers is greater when the patient's arm is in extension than when it is in flexion. In one aspect, the upper arm unit is configured to connect to a portion of the patient's arm between the patient's elbow and shoulder and the lower arm unit is configured to connect to a portion of the patient's arm intermediate the patient's hand and elbow.

摘要： A hand tool comprises: a body; a handle extending from the body; a hand-operable lever pivotally connected to the body and pivotable from a resting position towards the handle to a working position; a shaft extending through the body along a longitundal axis, and movable between forward and reverse directions along the axis relative to the body; a shaft drive mechanism mounted to the body and operatively connected to the shaft and lever such that pivoting of the lever to the working position causes the shaft drive mechanism to incrementally advance the shaft only in the forward direction; and a shaft release mechanism mounted to the body and comprising a shaft locking member operatively connected to the shaft and lever, wherein the shaft locking member is movable by the lever between a locking position and an unlocking position, and wherein movement of the lever from the resting position away from the working position moves the shaft locking member to the unlocking position and enables the shaft to be moved in the reverse direction.
