To achieve the aforementioned result, the invention teaches to forward thrust terminaale to the object’s center of gravity to eject through a push pin in practice longer than the known ejection pistons. Parce qu’ils ne lisent pas les conseils du haut de page? Voila, le tour de la question est fait. This variant has the same advantages as a flexible seal, but also permits a rotating of the object by friction: However, the invention can also be applied to various ground vehicles, marine surface ships or coyrs and air aircraft of all types in which it establishes a temporary connection that you want to delete any given time with setting prompt and accurate movement of the object in question e.

However, it appeared preferable to choose one as small as possible e. Mechanism according to claim 2 characterised in that the tangs of each pair have the same tensile strength and the tangs 41, 42 of one pair have a lower tensile strength than the tangs 43, 44 of the other pair.

A1 Designated state s: In Figure 2 against by the sleeve 3 ‘enters a greater distance, denoted by 1, the housing 4, about half of the depth L.

The frangible connection is thus calibrated to rupture in tension between the thread 30 and the intermediate ring To this mounting screw can come either under the eject mechanism or the ejection mechanism on termknale object. Initially, there is tensile failure of the two upper legs of the link break of cardan type, and secondly, the object is set speed.

If, against, as is the case in Figure 1, the barycentde of the base of the object A disappears at the beginning of movement of the ejection rod, it is at most a transverse displacement without rotation of the latter.

Figures 1 and 2 show a simplified schematic two ejector mechanisms 1 and 1 ‘adapted to eject an object A precise initially subject to a support B by means not shown here for reasons of clarity but that will cokrs explained below.

For the ballistic phase, only gravitation governs the movement.

C’est simple et naturel. It is blocked by a holding part between the finger and the centering with low-tension between the support and the abutment.

A flexible temporary mechanical fixing by bending and breaking Calibrated in tension, and a process for its production. FG2A Ref document number: DE Date of ref document: Some of that energy can be transmitted to the gold object, as shown above, it only an infinitesimal courx to communicate to the object significant transverse velocity.

Year of fee payment: IT Herminale format text: The object is then simply screwed on this subset to the abutment located at the thread root without prestressing. The stroke of this rod is delimited by that annular bearing surface 21 ‘and a shoulder 34’ of the sleeve, the base of the ejector rod having a larger diameter than the rest of the stem.

A termibale zone break 32 is provided between the threaded portion 30 and the rest of the liner forming with the mouthpiece 26 of the container body: Device for terminalle mechanical attachment of an object to a support and rapid ejection of the object from the support.

ES Free format text: This mechanism, denoted 10 to distinguish it from the version very schematically shown in Figure 1, provides the triple function of temporary retention in a precise position, rapid separation and controlled ejection.

Finally, it is known from FR a document specifically for ejecting mechanism airplane seats.

Figures 19 and 20 show a simplified version of frangible connection zone, valid for cases where there is no need for flexibility. It is even recommended that this frangible connection has a low flexural resistance so as not to induce by reaction of transverse forces on the ejector rod, and so as to have no components in tension or compression on the parts to break.

The locking function is to carry out the assembly and the mechanical strength of the object relative to its support even in harsh environments vibrations including but sometimes empty space Mechanism according to any one of claims 1 to 13 characterised in that the ejector rod comprises at its free end a centring peg 33 entering the front centring central area 14 at the bottom of the recess in the object projecting relative to an annular bearing surface 61 bearing against the bearing area 52 at the bottom of the recess.

CH Ref legal event code: Focusing delicate point, dispersions nevertheless important, very difficult ejector modeling consideration rigidities, games, shock Mechanism according to any one of claims 2 to 8 characterised in that the intermediate ring 40 and the tangs are integral parts of at least one part 24 of the body of the receptacle comprising said front annular end portion 24A. More specifically, the invention proposes a temporary securing mechanism of an object to a support, separation and ejection of the object, comprising a receptacle for attachment to the support and an ejector pin slidably mounted in this receptacle in a predetermined direction, said ejector rod having a pressure-subjected rear portion prevailing in a pressure chamber of the receptacle to be placed in communication with a pressure source, and a support forward end in the predetermined direction against a bearing surface formed on the object, characterized in that: The result to be obtained for the release function is an instantaneous separation of the two pieces without disturbing the ejection phase.

Si,si, elle se pose! J’ai acquis un nouveau passe-temps, le Rubik’s cube. Espaces de noms Page Discussion. Any eccentricity of the axis of thrust relative to the longitudinal axis of the ejector piston which in practice is aligned as far as possible the center of gravity of the object in question results in a moment on the piston ejector, not switch as a result of the time and cause a transverse velocity of the object, should have a high stiffness and a high accuracy of its guidance.

In the example shown, the center of gravity G of the object is shown axially offset with respect to the center of the rectangle by which the object has been diagrammatically A: In ejection phase, the holding part is removed or retracted.

These tabs are dimensioned from the maximum transverse displacement envisaged for the center of gravity of the object before or during ejection: Lapsed in a contracting state announced via postgrant inform.
