FR2650329A1 - Mechanical device for the emergency opening from outside of articulated (folding) doors of all types and on all vehicles - Google Patents

Abstract

The invention relates to a mechanical device making it possible to open, without effort and from the outside if needs be, an articulated (folding) door actuated by a control system, the force of which is electrical, pneumatic or some other force, independently of these normal service forces. The device consists of a set of eight main components comprising, in particular, a support 1 holding a hand grip 2 which is accessible from outside the vehicle and connected by a connecting rod 3 to a lever 4 fixed to the same support as before and which actuates a ring 5 which uncouples the original systems as they are, or modified.

Description

The swinging doors of vehicles are actuated by devices whose service force is electric, pneumatic or other.

To my knowledge, there was no simple and reliable methane device allowing to open "by the second", in the event of an emergency, per the outside of a vehicle with its swinging door, the usual service force being assumed become unusable.

The present invention relates to such a device, very simple, the principle of which is as follows
A particularly rigid support maintains a handle accessible from outside the vehicle and located in a housing arranged in the body of said vehicle. This handle is connected by a link with two ball joints È a lever held by the same support ue previously. The lever actuates a ring yes itself, either ctisnne the internal mechanical opening system pre-existing, or uncouples the original system modified as below ex pli @ ué.

 The invented device is constituted by an ansamble of eight main parts including a support (1) holding a handle (2) accessible Far outside the vehicle and connected by a link (3) to a lever (4! Fixed on the same support that previously and which activates a ring (5) which uncouples the control origin systems of the swinging doors, taken as existing or mafified.

When the sliding door control system does not have an internal and mechanical safety opening device, the door arm will be cut at the exit of the driving group. The removed section of the arm will be replaced by a notched section in two parts: as, each fixed to the two new sections of the aforementioned arm. The two sections or door arms are coupled by the ring of the invented device, and uncoupled by the same ring if necessary.

The reduction of the invented device is such that the action on the external handle does not require any particular effort. The handle is pulled from bottom to
The invented device will have different dimensions depending on the vehicles and the control system with which they are fitted.

Consequently, in the present patent filing, there is an example of a device applied to a very specific type of vehicle.

Any device of the invention comprises eight main parts as follows: pieces n 1 - rigid sup @ ort piece n 2 - external handle piece n 3 - link with two ball joints pie ce n0 4 - lever piece n 5 - ring piece n 6 - handle pin and accessories part no. 7 - lever axis and accessories part no. 8 - ring axis and accessories
The present invention relates only to any control system for swinging doors on all vehicles: ... / ...
