FR2848199A1 - Conical object grasping device for use at accident spot, has bridles with wide diameter orifice to allow entry of object, membrane held at interior of tube to define volume held in pressure for obtaining strain on walls of object - Google Patents

Abstract

The device has two bridles (1) with a wide diameter orifice (6) to permit entry of a conical object and a tube (2) squeezed by the bridles. The tube has increased external diameter and has a laterally netted hole (5) to receive a valve. A membrane (4) is held at an interior of the tube to define a volume held in pressure for obtaining a strain on walls of an object. A shoulder (9) allows centering of the object.

Description

i

  The present invention is a conical object gripping system for handling it mechanically.

  Handling is traditionally done by hand and in a place where vehicles circulate.

  The manipulation of this conical object in places where vehicles and workers on foot coexist is a source of incident, this gripping system associated with a mechanism makes it possible to limit this cohabitation and therefore to limit the number of risks.

  This device has a large diameter orifice into which the object of conical shape can be introduced, a membrane inside is pressurized in order to obtain a force on the walls of the object of conical shape.

  Method of realization: A cylindrical membrane (2) is stretched inside a tube (2), two flanges (1) of bevelled shape, tightened between them come to maintain and ensure the tightness of the iS assembly.

  The flanges (1) can receive a fixing system, a suitable shoulder (9) ensures protection of the membrane (4) and centering of the object in conical shape (10). The tube (2) has a specific shape with an increase in the outside diameter (7), it has a threaded hole (5) lateral to receive a valve.

  Four rods (3) ensure the tightening.

  The accompanying drawings illustrate the invention: The drawings illustrating the device are shown in sectional view of the assembled head. Referring to Figure 1 the device comprises 2 flanges (1) provided with a large diameter orifice and four holes (11) of smaller diameter.

  A tube (2) of specific shape with a threaded hole (5) placed in the center of the two flanges (1) Four clamping rods (3) A membrane (4) is stretched inside the tube (2) A hole ( 5) A large diameter orifice (6) An increase in the external diameter (7) of the tube (2) A change in internal diameter (8) of the flanges (1) A shoulder (9) 2 An object of conical shape (10) is shown 2 A clamping hole (11) The two flanges (1) and the tube (2) are made of plastic or a suitable metal.

  The membrane will be made of rubber or a flexible material. By way of nonlimiting example, the mounted head will have an overall dimension of 23 cm and 12 cm in height, with reference to FIG. 1.

Claims (5)
