FR2647847A1 - Protective device for door edges - Google Patents

Abstract

Device with which it is possible to prevent any risk of the fingers being severed during closure of the door. When this security door is placed against the door frame, a free or empty space of approximately 20 mm is left on the two lateral sides (hinges and lock). This gap or space is filled by activating a spacing mechanism which pushes two internal frames 4 and 8 from both sides until they press against the door frame 1. The spacing mechanisms can be eccentric multiples - pinion, rack - or others controlled manually, electrically, electronically or by other means.

Description

 Which of us, in our lifetime, has not seen or heard of an accident caused by a door? Perhaps he was the victim himself! Often benign but always painful, the wounds by door mainly affect young children, without sparing adults and the seriousness of these traumas, goes from the simple crushing of the finger with very often loss of the uncle, to the total cutting of a or more phalanges.

 The traditional door has the external dimensions of the internal dimensions of the frame that receives it. Thereby. a door open at 4V relative to the frame, reveals a Day of about 10 mm between itself and the frame. At closing, this day turns into a real shear which unfortunately every year kills many people.

 The present invention makes it possible to remedy this, by completely eliminating the risks of severing of the fingers.

 The present invention relates to a self-sliding interior distribution door, making it possible, by its operation, to avoid any risk of fingers being cut.

This door, of simple design includes 2 sliding parts which move apart each side by means of a mechanical means controlled manually (door handle) or electrically
iSwitch). Each sliding part is pressed against the door square.

The device of this sliding car door includes five essential parts -:
- 2 exterior door covers
- 2 guided sliding frames (sandwiched between the two
skins
- 1 device for controlling the lateral movement of the chassis
Figure 1 shows an exterior view of the door in position * not locked *
Figure 2 shows the device in the so-called open position
The sliding frames (4) and (8) are retracted
* +
Figure 3 shows the device in the so-called closed position
The sliding frames (4) and (8) are plated on either side of the door frame
Figures 4 and 5 show in cross section through the door handle, the two positions described above
the assembly according to the invention comprises a frame (i) on which a leaf is mounted by means of the hinges (7). The leaf has two door covers. two laterally guided sliding frames (4) and (P) sandwiched between the two linings over the entire height of the door and a device for controlling the lateral movement of the frames (4) and (8). The control device consisting of a handle this maneuver introduced into a square (6) causing an eccentric cen
tral (2) and two eccentrics (2) one in the high position the other in the low position. These two eccentrics being connected to the central eccentric by a system of rods (5). Each eccentric is connected to the sliding frames (4) and (8) by connecting rods (3). The door comprising guides (9)
Selor. the invention. the lateral movement of the sliding frames is created by means of a handle secured to an eccentric; The latter, by means of two rods transmits its own movement to two other identical exer.tric located, one in the lower part of the door, 1 other in the upper part
In the closed position the eccentrics separate the two sliding frames (4) and (8) until they are placed on either side of the door frame
Each eccentric is also linked to the sliding frames by means of 2 small connecting rods. this in order to bring these blackcurrants inward, ie er. open position
Other movement transformation systems can replace the eccentrics. One can imagine for example. a gable / chain link system which would undoubtedly be better suited to the mazes wear view bridge, as well as smooth control.

The sliding frames are guided during their movement and it can be made very soft by interposing teflor strips. between parties in contact
The present invention materializes a principle of implementation and simple operation or reliability can be of high level depending on the materials used for the realization of the whole.
The essential object of the device according to the invention is to avoid accidents due to the shearing effect of the conventional door with its frame.

Claims (5)
