摘要:
A device for closing a passageway, which device comprises a closing body that can be moved by means of a motor along a guiding from a closed position to an open position and vice versa, wherein the body is provided with a safety sensor interrupting the motor feed, is incorporated in a circuit with separate feed connected fixedly to the movable body and the circuit is provided with a conductor which extends in the direction of movement and which is guided slidably along at least one fixed coil disposed close to the guiding, which coil is a part of the control circuit for the motor, wherein the safety sensor comprises one or more break contacts connected in series, and further connected in series with a capacitor in the circuit so being able to measure the frequency change in the circuit, instead of operating on the usual measuring of a resistance or power change when the sensor is activated.

A device for manufacturing a fence post of mouldable material and provided with a reinforcement (12), which device comprises at least a multipart mould (1) with infeed (5) and air release opening (6), wherein the mould (1) is embodied with a lost part (11) on a longitudinal partition plane thereof, which lost part (11) forms a part of the end product, whereby as fence post this product can easily be provided with fixing members, for instance for fence wire mesh, and which end product is light in weight and easy to place in the ground.
摘要:
Ein Tor zum Abschliessen eines Durchgangs, das im wesentlichen aus mindestens einem Pfosten (4) und einem bezüglich dieses Pfostens (4) bewegbaren Teil besteht, der durch ein Gebilde von aufrechtstehenden, durch eine Querverbindung verbundenen Stäben (2) gebildet wird, wobei die Querverbindung aus einem Träger (1) mit Öffnungen zur Aufnahme eines jeweiligen Stabs besteht, wobei jeder Stab mittels einem im Träger untergebrachten Vorspannelement (6) zur Befestigung am Träger versehen ist, damit die Konstruktion nunmehr auf nahezu einen Hauptträger und vertikale Stäbe beschränkt ist, sodaß der Transport des Tors im nicht montierten Zustand erfolgen kann, und die endgültige Montage an der Gebrauchsstelle durchgeführt werden kann.

摘要:
A method for manufacturing a fence consisting of two posts standing at a mutual distance and a lower and upper beam with a mesh of intersecting wires supported therebetween, which is distinguished by
aranging in or on the posts and/or the beams a channel-like fixing member provided with outward converging walls. sliding an edge strip of the mesh into the opening of the channel, tensioning the mesh by exerting a tensile force on the parallel channel-like members, mutually fixing the posts while maintaining the tensile force, and releasing the tensile force, with which method a fence is obtained which makes any further strengthening in the section unnecessary.
摘要:
Connection of two tubular elements, such as a rail (3) and an upright (4) of a fence assembly or gate, which are placed onto each other at an angle, wherein the one element is placed in a suitable hole in the side wall of the other element and is connected to the other element by bulging of the wall of the one element, and wherein a strip (9) extending to the expanded part is provided on the edge of the hole in order to reduce the surface tensions between the edge of the hole and the one element.
摘要:
A device for attaching a picket (3') to a rail (1), particularly suitable for fence assemblies and the like, which rail (1) is at least embodied as a tubular profile and has at least a hole (6) in a wall thereof for receiving the picket (3'), wherein the picket has a transverse through-hole (8) for receiving a pin (9) of a length such that the pin (9) protrudes on either side of the picket (3'), said pin (9) being of sufficient stiffnes to connect the picket (3') to the tube without the need of additional heat treatments, such as welding, or complicated assembly operations, in conjunction with screw connections so deminishing transport and assembling costs.
