DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a safety device for equipping, over at least a part of their height, the vertical edge of a door and the adjacent jamb, on the hinge side, for preventing babies and young children from putting their fingers or hands in the passage left free between said door and said jamb, when the door is open.
The closure of doors by a third person, or even by an air current, daily causes accidents ranging from a simple traumatism of the phalanges by crushing to sectioning thereof: this is the most frequent cause of accidents occurring to small children.
Different devices have been proposed for remedying this situation and among them devices formed of a rigid or semi-rigid elongate piece having longitudinal subdivision lines defining two marginal strips and a central zone of variable geometry, said marginal strips being adapted to be fixed respectively on the jamb and on said vertical edge of the door whereas the variable geometry zone projects freely outside the jamb, said variable geometry zone being able to pass from a configuration which is at least relatively flattened, in the closed position of the door, to an opened out configuration in the open position of the door.
Such devices are described for example in FR-A-2 282 032, GB-A-2 203 473 and GB-A-2 019 475.
These known devices have a common drawback, that of being cumbersome to store and awkward to pack.
In fact, the device described in FR-A-2 282 032 is, as the applicant himself defines it, a bellows which involves a folded construction by manufacture.
The device described in GB-A-2 203 473 is a plastic V shaped strip, like the device described in GB-A-2 019 475 which, in addition, is provided with tongues at the free ends of the V and, outwardly, at the tip of the V.
The aim of the present invention is to overcome this drawback, which aim is reached in that a device is provided which has a flat configuration before fitting.
In a first embodiment, the strips and the variable geometry zone of the elongate piece forming the device are independent elements joined to a flexible material layer forming a common lining and, advantageously, the strips and the variable geometry zone are joined to the flexible material layer by an adhesive.
In a second embodiment, the strips and the variable geometry zone are formed in a single piece and defined by zones of material of lesser thickness allowing their articulation.
In a third embodiment, the strips and the variable geometry zone are independent elements included in a common envelope made from a flexible material.
In a fourth embodiment, the marginal strips and the variable geometry zone are independent elements joined together by a bridge of flexible material having high flexion strength.
In a first variant of the fourth embodiment, the longitudinal edges of each flexible material bridge merges with those of the adjacent strips.
In a second variant, each flexible material bridge has an H profile, the edge of the strips to be joined together being housed between the vertical bars of the H on each side of the horizontal bar thereof.
In a third variant, each flexible material bridge has a T profile, an edge of the strips to be joined together being housed along the two parts of the horizontal bar of the T on each side of the vertical bar thereof.
To facilitate articulation, one of the faces of the material bridge is advantageously concave.
Preferably, the marginal strips and the variable geometry zone are made from a rigid or semi-rigid plastic material, for example from polyvinyl chloride and the material bridges are made from a flexible plastic material for example from an alkylene (preferably butylene) terephthalate copolymer, having glycol polyether chains such as the product commercialized under the trademark Hytrel by E. I. Dupont de Nemours.
In practice, the variable geometry zone may be formed by at least two central strips.
In a preferred embodiment, the device is adapted to be placed on the external face of the door such as seen with respect to its opening direction, for it is from t
