Description

The present invention relates to a door provided with a security according to the preamble of claim 1.

Commonly used doors include usually a panel hinged in a frame around of a joint. This type of door presents a risk major accident when, for any reason, the hinged panel closes violently in the frame. In indeed, a person, especially a child, who would have his hand on the amount of the frame which is opposite the joint, might see his fingers violently trapped between said frame and said panel Speak clearly.

It is well known in the state of the art of devices intended to brake the closing of the panel articulated so the risk of getting your fingers caught is greatly decreased. However, these devices are quite complicated and expensive to manufacture since they often include means such as jacks for brake. Similarly, these devices do not prevent not completely closing the door so that a no one can ever get their hand caught between the frame and the door.

Document DE-C-341 286 discloses a device for lock a window in the open position. However, after unlocking the window from its open position, nothing prevents it from closing completely suddenly hurting someone.

Document DE-A-26 14 822 discloses a device for prevent accidental complete closing of a door, which comprises a movable member movable directly by the user enters his two positions. The device is therefore not automatic and if security is not activated beforehand, the risk of accident is not deleted.

Documents US-A-2,846,713 and US-A-4,261,140 also disclose devices of this type.

The object of the present invention is to provide a safety device for a door that is simple and inexpensive to make. The present invention also intended to provide such a safety device for a door that automatically prevents closing complete accidental door. The present invention also aims to provide such a device for security for a door that automatically and all the knocks that fingers placed on the frame of the door are accidentally stuck when closing of it.

The present invention therefore relates to a door fitted with a safety device to prevent automatically an accidental complete closure of said door comprising at least one panel provided with a handle and articulated in a frame, said device comprising a movable member movable between a position security, in which it prevents closing complete door and a closed position in which the door can be closed, said movable member being connected to an actuator so that actuation of the actuator moves said member movable to its closed position, characterized in that said actuating member is formed by the Door handle.

So there is a need for intervention of a person on the actuator to be able to close the door completely. This is a guarantee against all possibilities of accident since the person who acts on the actuator will have previously removed his hand from the frame.

Preferably, in the safety position of the movable member, the edge of the hinged panel which is opposite the door hinge and the amount corresponding to the frame define a spacing of at least minus a few inches, so the fingers of a hand cannot be pinched between said edge and said amount.

So, if the door closes violently, under for example the effect of a draft, a person who would have his hand placed on the frame on the side opposite to the door hinge would not risk get your fingers caught since the door would be stopped by said movable member, the minimum spacing which is defined by the invention corresponding approximately to the thickness of a person's hand.

Advantageously, said movable member is disposed at level of the upper edge of the hinged panel of the door.

Advantageously, said movable member, in its safety position, extends beyond the upper edge of the hinged panel so that it cooperates with the frame or an element integral with said frame to prevent closing the door completely, and in its position closing, is arranged below the upper edge hinged panel so that the door can be closed.

Preferably, said movable member is biased towards its safety position by a spring.

Advantageously, said movable member and said spring are arranged in a hollow cylinder fixed in said hinged door panel.

Advantageously, said movable member is connected to said cable actuator.

Preferably, said movable member, in its position safety, cooperates with a stop element fixed on the frame lintel.

Advantageously, the door frame is standard and has a standard rebate.

Other characteristics and advantages of the present invention will appear during the following detailed description, given by way of nonlimiting example with reference to the accompanying drawings, in which:

FIG. 2 is a schematic sectional view of the device according to an embodiment of the invention,

FIG. 3 is a schematic front view of a device according to an embodiment of the invention,

FIG. 4 is a schematic sectional representation of a door handle incorporating a device according to the invention, and

Figure 5 is a schematic top view of a door handle incorporating a safety device according to the invention.

With reference to FIGS. 1 and 2, the door according to one mode embodiment of the invention comprises an articulated panel 2 which fits into a frame. Panel 2 is hinged around a hinge 8. The frame includes a lintel 6 which connects two uprights 4 and 5. The upright located near articulation 8 of panel 2 will be designated subsequently per carrying amount 4 and the amount opposite articulation 8 of panel 2 will be designated subsequently per non-carrying amount 5. As visible in particular in Figures 1 and 2, the frame can be standard and may include a rebate of the conventional type. The panel articulated 2 comprises an actuating member 3 which is advantageously formed by a handle intended to actuate the door.

According to the invention, there is provided a movable member 10 which moves between a safety position in which prevents the complete closing of door 1 and a closed position in which it allows the door 1 is completely closed. This movable member 10 is preferably arranged at the upper edge of the hinged panel 2 of door 1, as shown in the Figures 2 and 3. Advantageously, this movable member, in its safety position shown in FIGS. 2 and 3, projects above the top edge of the panel hinged 2 so that it prevents the complete closing of the door by cooperating with either the lintel 6 of the frame itself, either with an element 7 integral with said lintel 6. In with reference to FIGS. 1, 2 and 3, provision is made advantageously a stop element 7 which is fixed on the lintel 6 of the frame with which said movable member 10 cooperates to stop door 1 in the event of closure accidental. As can be seen more particularly on the Figure 1, when the movable member 10 cooperates with said stop element 7, a minimum spacing E is defined between the edge 2a of the hinged panel 2 which is opposite to the articulation 8 and the non-bearing amount 5 of the frame, of so that a person who would have his fingers laid on this place wouldn't risk getting caught even during an accidental or even violent closure of the panel 2.

According to the invention, said movable member 10 is connected to door handle 3 so that the actuation of the handle 3 moves said member 10 from its position safety towards its closed position. Advantageously, said movable member 10 is connected to the handle 3 by a cable 20. This cable can be of any type and can especially be similar to a bicycle cable. Advantageously, said movable member 10 is biased towards its safety position by a spring 11, or any other equivalent elastic means, so that without intervention on the handle 3 of the door, the movable member 10 is in its safety position and abuts against the element of stop 7 to prevent complete closing of the door. Complete closure only becomes possible after actuation of the handle which, via the cable 20 moves the movable member 10 against the force of the spring 11 towards its closed position. Advantageously, the movable member 10 and possibly the spring 11 are placed in a hollow cylinder 15, fixed in said panel hinged door 2. This implementation allows a reinforcement at said movable member 10 so that in the event of violent closure of the articulated panel 2, said hollow cylinder absorbs part of the forces of inertia to avoid damage to the door, particular of the upper edge of the panel 2.

Cable 20 can be fixed in any way known desired to the movable member 10 on the one hand, and to the handle 3 on the other hand. Possibly, means of adjustment to precisely adjust the fixing of the cable 20 on the movable member 10 and the handle 3 can be provided at both ends of said cable 20.

The operation of the device according to the invention is so very simple: when the panel 2 of door 1 is closes, the movable member 10 protrudes above the hinged panel 2, so that it will cooperate with the stop element 7 fixed on the lintel 6 of the frame for prevent the door from closing completely and guarantee the minimum distance E between the articulated panel 2 and the non-bearing amount 5 of the frame. To close completely the door, it is necessary to operate the handle 3, particular to lower it, which as depicted on the Figure 4 exerts traction on the cable 20, this traction being transmitted to the movable member 10, against the force of the spring 11 so that the movable member 10 moves to its closed position where it is arranged completely inside the hollow cylinder 15 fixed in the hinged panel 2 of the door. So the door can be completely closed and the risk of getting caught fingers during this process sucks.

Although the present invention has been described in reference to a particular embodiment of the invention, it is understood that all other variants equivalents which fall within the scope of the claims could be used. So the organ mobile 10 can cooperate directly with lintel 6 of frame to prevent the door from closing. Moreover, the movable member can be arranged at the edge top of panel 2, outside of it.
