A boarding and/or entry aid for vehicles for carrying passengers is described, having a rectangular frame (3) and a step plate (2) supported movably in it. The frame (3) has two parallel lateral parts (4), which are joined together at rear ends by an end profile (5) and in a region spaced apart from it by at least one bracing strut. The lateral parts (4), end profile (5) and bracing strut are provided according to the invention with positioning means (14, 15) that engage one another in form-locking fashion.

Elements, couplers, systems, and methods for joining two or more trough members. A locking element for coupling a coupler to a trough member can include a main body, a clip member configured to couple the main body to the coupler, a first arm extending from the main body, the first arm being configured to flex relative to the main body, and a first barb coupled to the first arm, wherein the first barb extends to a first point configured to engage an exterior surface of a first trough member.
摘要:
A joining arrangement for use in the construction of stud frames and for releasable attachment of a first structural member to a second structural member forming part of the frame. The first member includes in at least one side wall a female recess which, when the members are joined, engages a corresponding male protrusion in at least one wall of the second member. The respective formations in the first and second members engage such that they are generally in alignment thereby securing the first member to the second member and wherein the first member is a stud and the second member is a plate.

摘要:
Couplers for a cable trough system including a spacing defined by first and second guiding surfaces, the spacing being sized to receive the terminal end of a trough member into the spacing. One or more springs are carried on the couplers and may be at least partially disposed within the spacing between the first and the second guiding surfaces. The springs urge the terminal end of the trough member against the coupler upon insertion of the terminal end into the spacing. One or more locking elements are coupled adjacent to the springs to move between a locking position and a released position. The locking elements may slide longitudinally or move perpendicularly to the couplers. A first trough member may be released from the couplers independent from a second trough member coupled to the couplers. Methods for use of the couplers are also provided.

A fastening bracket system for connecting two abutting members at a fixed angle includes a locking bracket having a flange and attached to one member and a channel bracket having a channel and attached to the other member. The channel or the flange, or both, is tapered. The flange is inserted into the channel until it becomes locked. Multiple locking brackets and channel brackets may be used in series to form longer joints. A method of assembling a joint from two abutting members at a fixed angle includes the steps of attaching at least one locking bracket having a flange to one of the members and at least one channel bracket having a channel to the other member, either the flange or the channel being tapered; positioning the members in the desired angle; and inserting the flange into the channel until it is locked, thereby locking the brackets together and securing the two members in position.

A connecting rod includes first and second ball joints made of ball-shanks and holders tiltably connected with the ball-shanks. A connecting portion, which connects the holders of the first and second ball joints, adjusts the distance between the centers of the ball-shanks. The connecting portion includes first and second connecting arms integrally formed with the holders of the first and second ball joints and on which a plurality of positioning concaves and convexes which are meshed with each other are respectively arranged in a longitudinal direction. A fixing device engages the first and second connecting arms with each other in the condition where the positioning concaves and convexes of the first and second connecting arms mesh with each other.

A structure includes an electronic device support, an electronic device, and a fastener for the electronic device support and the electronic device. There is a first dovetail slot in the electronic device support and a second dovetail slot in the electronic device. The first dovetail slot and the second dovetail slot are in a facing relationship. A bar of a shape-memory alloy in the recovered state is received into the first slot and the second slot and has a cross sectional shape with V-shaped grooves on its opposing lateral sides engaging the first dovetail slot and the second dovetail slot.
