FR3039847A1 - LATCH FOR ARTICULATED DOORS OF ALL SIZES TO OPEN THESE DOORS BY LIFTING A LEVER AND OBTAINING THEIR CLOSURE SIMPLY BY PUSHING THEM - Google Patents

Abstract

Device for opening the doors with a lever and closing them simply by pushing them. The invention relates to a device for faster handling of opening and closing doors of any kind. It consists of a handle operated latch actuated from the bottom up, fixed on the movable part of the door, and being embedded automatically when pushing the door in a lug fixed on the doorframe. It can be completed by a second lower lock, depending on the upper lock and opening and closing automatically when handling it. The device according to the invention can be used on all kinds of pivoting doors and of any size.

Description

The present invention relates to a device for opening the doors with a lever and close them simply by pushing them. The opening of the doors is traditionally performed using a latch that slides laterally in one direction to open and the other direction to close.

The device according to the invention makes it possible to remedy these maneuvers. It comprises in fact according to a first feature, a round lock eccentric at its end fixed to the door by two bearings, between these two bearings is fixed a handle, which, in the closed position, is vertical to the door downwards.

According to a second feature a lug is fixed on the door jamb in which engages the eccentric portion of the latch actuated by the handle.

The device can be completed by a second lower closure when its use requires it, especially with large doors and more particularly in a free animal farm building.

The accompanying drawings illustrate the invention:

Figure 1 shows the device seen from the front.

Figure 2 shows the device seen in profile, the latch in the engagement position.

Figure 3, in the upper position of engagement.

Figure 4 in the locked position, the control handle 2 resting on the door 14.

Figure 5 shows the double locking device seen from the front.

Figure 6 shows the device seen in profile and locked.

The round lock 3 is eccentric at its outer end of the door 14 by a part 4 connected to the latch 5 coming into the latch 6. For ideal operating conditions, since 3 and 5 have an equal diameter, the center of these rounds should be spaced 16 / 9th of their diameter. By way of example, as illustrated in FIG. 2, rounds 3 and 5 of diameter 18 mm should be separated at their center C and C 'by a distance D of 32 mm. A separation distance of less than 16: 9 would negatively impact the ease of use of the system. It can however be greater, which also facilitates the operation of the device but requires to enlarge the lug 6, fixed on the door jamb 15.

Referring to these drawings (Figure 2) where the latch 5 is in the attacking position on the inclined portion of the lug 6.

Referring to these drawings (Figure 3) the latch 5 is in the high position ready to descend into its closure housing in the latch 6. The Y slope of the latch can not be less than 45 °. The angle formed by an imaginary line X and X 'symbolizing the centers of the two locks 3 and 5 and the handle 2 must be 45 °.

Referring to these drawings (Figure 4) the latch 5 down into its housing of the latch 6, the handle 2 must necessarily be based on the door 14, so that any internal thrust triggers the latch 5.

Referring to these drawings (Figure 5) was added a lower closure comprising an iron spar 10 articulated on the door at 9, guided at 11 and locked in closing by a latch 13. This spar 10 is maneuvered for its engagement at the triggering by a rod 8 hinged on the gap 12 at the bottom, this rod 8 hinged at 7 on the lock 5.

The weight of the opening control handle 2 is important for the closure of the latch 5 when it is simple, it is less with this assembly since it brings a certain weight more. With reference to these drawings, FIG. 6 shows the closed double lock.

Claims (6)

1) Device for opening the revolving doors by simply lifting a lever and pushing to close them. 2) Characterized by a lever 2 whose weight must always bring the lock in the closed position 3) Characterized by a lug having a minimum angle of attack of 45 ° on which the lock slides before falling back into its closure housing 4) Characterized by a 45 ° angle between the opening handle and the offset lock 5 5) Characterized by its realization that can be manufactured in any dimension 6) Characterized by the addition of a double lower lock for large doors requiring it for their use and safety.
