FR2918474A1 - Internal stop for pivot connection in outdoor game machine, has flexible elastomers and circular arc shaped movable stop part rotatably driving one of flexible elastomers contacting with fixed stop part - Google Patents

Abstract

The stop has flexible elastomers (3) and a circular arc shaped movable stop part (1) rotatably driving one of the elastomers contacting with a circular arc shaped fixed stop part (2). Amplitude angle of rotational movement of a pivot connection is equal to the sum of values of angles of rotational movements generated by the movable and fixed stop parts subtracted from 360 degree while considering size and elasticity modulus of the elastomers. The pivot connection is provided between movable parts of an outdoor game machine.

Description

Our invention relates to an inner stop for stopping in

rotation of a pivot link.

  Traditionally, outdoor games did not have moving parts. Two parts moving relative to each other produce a hazard that has no solution on existing outdoor game devices. Our invention makes it possible to stop the desired rotation while not exposing the user to hypothetical pinches of fingers. Our stop is actually composed of a moving part, a fixed part and elastomers present in order to limit the shocks during the rotational stop of the pivot connection. The stops of the fixed and mobile parts are in the shape of an arc of a circle

  According to the applications of achievements: - the movable stop can be carried out in the base housing or welded thereto. - The angle of the amplitude achieved by the movement (y) of the pivot connection depends on the angle a (angle generated by the sides of the fixed stop) and the angle p (angle generated by the sides of the movable stop) (see Figure 1). The elastomers must be made of flexible material in order to slow down the movement of the pivot connection before stopping it completely. - The elastomer is not attached to one of the two parts. 2918474 - 2 -

  The accompanying drawings show the invention: - Figure 1 shows a diagram with the useful angles and the operation of the system. FIG. 2 represents a side view of the invention FIG. 3 represents a 3D view of the device

  With reference to these drawings, our system comprises a movable stop (1) which, by its movement, will rotate one of the elastomers (3) which itself will come into contact with the fixed stop (2). Thanks to the properties of the material of the elastomer, the stoppage of movement will not be clear and avoid any shocks that can prematurely degrade the system by matting. The amplitude of the rotational movement (y) will be 360 minus the value of that generated by the surfaces of the fixed stop (a) plus the value of that generated by the movable stop (P) (y = 3600- ( a + (3)). (See Figure 1. It will also be necessary to take into account the size of the elastomers (3) and the coefficient of elasticity of these in the angle calculations.) According to the needs and means, the stops can be made directly in their respective bodies by mass machining or be made in two parts and welded to their body thereafter.

  This invention is intended in particular for outdoor sports machines which comprise movable parts in pivot connection between them.
