Abstract  (EN)

The invention relates to a buckling study device consisting of two guide columns, connected by a table which guarantees the stability of the device when carrying out tests. At the top, they are connected by a fixed load crossbar. The loading device fixed on the crosspiece consists of a threaded rod. At the end of the rod is attached a force measuring dynamometer with a digital display. The lower crosspiece is mobile, guided in translation by two pivot links sliding in the two columns. The latter is connected by a cable, this cable is connected to the dynamometer (14). Hence the rotation of the nut causes the rise of the rod. A compressive force is applied to the test specimen via this translation. A dial gauge displays the lateral deflection of the bar.

Abstract (EN)

The invention concerns the design and production of a vehicle windshield assembly and positioning trolley, called “ TRANS-CHARBARV1". Generally, the operations of installing and removing windows and windshields are carried out manually by two, three, and sometimes even four people, with the need for scaffolding, ladders, and/or stepladders to put on and fix the windshield breaks at their exact position. This trolley has the advantage of being mobile, adjustable, and therefore ergonomic, which can be handled by a single person, thanks to its modular structure. It is composed of a mobile and adjustable suction cup head using a linear module, an articulated structure with 4 bars, and a robust chassis composed of telescopic arms to guarantee the stability of the system. It is designed to facilitate the positioning (installation and removal) of windshields on vehicles and means of public transport. It is particularly useful in the case of industrial vehicles, buses,
