An auto-lock assembly for a telescoping mast having a plurality of telescoping tube sections configurable between a retracted position and an extended position is disclosed herein. Also disclosed herein is a telescoping mast, which includes a plurality of telescoping mast sections including a base tube, an intermediate tube, and an end tube, the intermediate and end tube adapted to be telescopically received in the base tube, a base auto-lock having a collar for mounting to the base tube, and an intermediate auto-lock having a collar for mounting to the intermediate tube. Further disclosed herein is an auto-lock for use with a telescoping mast having a plurality of tube sections.

A retaining pin comprising a body section having an aperture therein and being provided with a suction cup. An actuation mechanism arranged at a first end of the body section and a pin is connected at a first end to the actuation means and extends therefrom, through the aperture of the body section. An outer sleeve is arranged around the pin and in contact therewith and the outer sleeve comprises an expandable section that, upon operation of the actuation means, can be expanded from a first dimension to a second dimension.

A securing element for a motor vehicle has a hermetic body made of plastic which encloses a cavity. The cavity is filled with a filling medium. The thermal expansion coefficient of the filling medium is, up to a softening temperature of the plastic, greater than the thermal expansion coefficient of the plastic. A cover for an interior mirror base of a motor vehicle includes such a securing element.

A pneumatic clamping component includes a clamping member having a main body portion, an abutting portion, and clamping arms. Each clamping arm has a connecting portion and a clamping portion. A base has an accommodating cavity in communication with an air opening. The abutting portion, the clamping arms and an inner wall of the accommodating cavity jointly form an air chamber in communication with the air opening. The air opening is used for entry of air and keeps the air in the air chamber. The clamping portion is located outside the air chamber. A gap is located between the two clamping arms. When the air does not enter the air chamber, two clamping portions are not in contact with the to-be-clamped object. When the air enters the air chamber, a to-be-clamped object is located in the gap, and the two clamping portions clamp the to-be-clamped object.

A ball-lock type fastening device for connecting a work piece to a structure is disclosed. The fastening device includes a number of features designed to improve the reliability, repeatability and strength of the locking mechanism compared to traditional ball-lock fasteners. The features include the shape of the locking balls, the shape of the retention housing which engages the locking balls, and mechanisms for controlling deployment and retraction of the locking balls.

An apparatus for binding to a select surface and a method of use thereof is provided. The apparatus comprises a body, a flexible member, and a recess. The body has a proximal surface configured with a fluid port. The flexible member has a cavity therein and is operatively coupled to the body to form a seal with the body. The flexible member is configured to expand responsive to an expansive pressure within the cavity. The recess is formed by the proximal surface and the flexible member. The fluid port is configured to facilitate generation of a binding pressure within the recess.

A remotely controllable fastening device for the detachable connection of components has a longitudinal axis and at least one fastening body for insertion into a fastening base, wherein the fastening body has an anchor which is insertable into the fastening base, wherein, for the form-closing and/or frictional anchoring of the fastening device in the fastening base, the anchor is moveable in at least a first direction, and wherein, for the disengaging of the fastening device, the anchor is respectively moveable in a second direction which is contrary to the first direction, and wherein the anchor is connected with a drive which is remote operatable and which is provided for operation with a fluid and which is internally arranged, the anchor being moveable by the drive in at least the second direction.

Workpieces that generate pressure by an extrusion media (6, 6a) and are deformed in this way for the secure connection of components (7, 8). In particular, an extrusion billet which comprises an extrudable material or material mixture in the interior thereof, which can be reversibly compressed by a compression die (4) penetrating into the material, such that billet can expand in diameter by increasing the internal pressure in the billet, which leads to a very secure, but reversible press fitting of the different types of components to be connected, in particular of shaft-hub connections for mechanical engineering.

A system for changing work tools on a loading crane includes a first coupling member on the work tool side or the loading crane side with a receiving opening and a second coupling member on the loading crane side or the work tool side with a guide member extending along a longitudinal axis. The guide member engages in the receiving opening by moving the first and second coupling members toward each other. The first coupling member comprises a support surface for axially abutting the second coupling member and the second coupling member comprises a bearing surface complementary to the support surface and a locking element which is movable by a drive between disengaged and engaged positions. The locking element has a clamping surface for frictionally abutting the first coupling member and the first coupling member has an abutment surface complementary to the clamping surface for zero-play axial clamping of the first and second coupling members.
