Description

FIELD OF TECHNOLOGY. RELATED TO THE INVENTION

The present invention relates to a multifunctional door handle, in particular for fire exits equipped with a device for quickly opening a door by pressing a lever (anti-panic device), equipped on the inside.

KNOWN LEVEL OF TECHNOLOGY

Nowadays, and also referring to the prior art, multifunctional handles for fire exit doors usually use widely installed mechanisms on the external part of the door, which, when actuated, allow pulling back the valve of the anti-panic device located inside, when opening the aforementioned the door.

Many existing systems on the market allow the door to remain open or completely locked using the key in the corresponding lock cylinder located in the device, making it possible to pull back the slide bar valves for emergency exits, or without doing so. The movements of this mechanism in order to completely lock the door vary greatly in this type of system, but they all need additional components (usually spindles or screws), depending on which door handle is used. The mechanisms for opening or completely closing the door have three possible positions, two of which depend on the door handle, and thus, as soon as the latter is installed, the position of the mechanism that is not used (the one that corresponds to the other handle) must correspond to the “locked” position using additional components. This feature of existing multi-function fire door handles on the market makes them difficult to install and complicates the system.

DESCRIPTION OF THE INVENTION AND ITS ADVANTAGES

In view of this situation, the present invention relates to a multi-function handle for doors, in particular for fire doors, which includes an internal driven member from which a trip protrusion protrudes, which may be located on the right or left of the vertical axis of the multi-function handle in accordance with its assembled position, which depends on the opening rotation ("handle") of the door, and there is a cranked lever, which in a situation when the door is fully locked, is located at an angle to the vertical axis of the multifunctional handle on the side opposite to the position of the opening protrusion of the internal driven element, and the cranked lever can be connected by its side surfaces to the opening transmitter during the stage of transition of the door from fully locked to open or vice versa.

Thanks to this configuration, the multifunctional door handle is a device that can be used on both door handles having only two possible positions of the mechanism parts, without the need to add additional parts, such as screws or spindles for the locking position, which the mechanism would have if the handle would be installed on the other side. The use of an internal driven element and a cranked lever, which can have only two positions according to the opening turn, facilitates the installation of the mechanism and makes it less complicated. In addition, by acting with a key on the lock cylinder, it is very easy to change, going from the configuration when the door is fully locked to the open position or vice versa, since the crank lever performs a pendulum movement and its side surfaces are in contact with the opening transmitter, moving it horizontally so so that he takes the necessary position.

Another feature of the invention is that with its fingers, the locking lever can be connected to springs mounted in the transmission part.

Thanks to this configuration, there is no need to add any other parts to connect the locking lever to the mechanism, since the same springs are used that are installed in the transmission parts.

Another feature of the invention is that the supporting structure of the mechanism includes a flexible finger.

Thanks to this configuration, the supporting structure of the mechanism acquires the possibility of using a microswitch for cases where an electrical signal is required in the handle. It is not necessary to remove any part of the multi-function handle to insert the microswitch, since there is a flexible finger that can be pressed down to insert the microswitch, and the locking protrusion locks the position of the microswitch as soon as the compression of said flexible finger stops.

Another feature of the invention is that the supporting structure of the mechanism allows you to insert a microswitch that can be connected to the trigger protrusion that appears from the crank during the stage of transition of the door from fully locked to open or vice versa.

Thanks to this design, it is precisely the cranked lever that, with the help of the starting protrusion, activates and deactivates any microswitch inserted into the handle.

DESCRIPTION OF THE BEST MODE FOR CARRYING OUT THE INVENTION

With respect to the drawings and the above reference signs, a preferred embodiment of the invention is illustrated in the accompanying drawings regarding a multi-function handle for doors, in particular for fire doors, which includes an internal driven member (5) from which an opening protrusion (5c) arises, which can be located either to the right or to the left of the vertical axis (1a) of the multifunction handle (1) according to its assembled position, which depends on the opening rotation (“handle”) of the door, t the crank lever (4) is located, which, when the door is completely locked, is located at an angle to the vertical axis (1a) of the multi-function handle (1) on the opposite side of the opening protrusion (5c) of the inner driven element (5), the crank lever (4), which can be connected by its side surfaces (4b) to the opening transmitter (6) during the stage of transition of the door from the fully locked to the open position or vice versa.

FIG. 1a shows a mechanism with a fully locked door for a door handle with hinges to the left of the multifunction handle (1), consisting of a transmission part (3), a pair of springs (8), a locking lever (7), a cranked lever (4) that opens the transmitter (6 ) and the internal driven element (5). FIG. 1b depicts the same mechanism with a fully locked configuration for use on a door handle with hinges on the right. The position indicator (5b) of the inner driven member (5) shows on which side of the vertical axis (1a) of the multi-function handle (1) the opening protrusion (5c) is located. These two drawings depict only two possible configurations of the mechanism when it is completely locked, and you can see that no additional parts are required in order to use the multi-function handle (1) in various door handles.

In FIG. 3 shows a multi-function handle (1) in the initial position with the configuration of parts of its mechanism, ready to open the door. As seen in FIG. 4, acting on the handle (11), the external driven element in the form of a butterfly (12) comes into contact with the transmission part (3), forcing it to move down. The opening transmitter (6) is connected to said transmission part (3) by means of the guide projections (6a). The said guide projections (6a) of the opening transmitter (6) are located in the respective guide grooves (3a) provided in the transmission part (3). In addition, the fingers (7b) of the locking lever (7) are inserted into the springs (8) held by the transmission part (3) so that, since the transmission part (3) moves downward, the opening transmitter (6) and the locking lever (7) simultaneously moving down. The position of the opening transmitter (6) remains fixed due to the locking teeth (7a) included in the locking lever (7), which prevent the guide protrusions (6a) included in the said opening transmitter (6) from sliding along the guide grooves (3a) of the transmission part ( 3).

During the downward movement of the assembly of parts consisting of the transmission part (3), the locking lever (7) and the opening transmitter (6), with the multi-function handle (1) in the open position, the drive surface (6b) of the opening transmitter (6) comes into contact with the opening protrusion (5c), which appears from the internal driven element (5), forcing it to rotate. The said internal driven element (5) is a part connecting the multifunctional handle (1) with a mechanism that pulls back the valve of the device for quickly opening the emergency exit located on the inside of the door. Thus, since the inner driven member (5) is rotated, the retractor mechanism of the valve is actuated and the door opens.

In addition, if a key is used to act on the lock cylinder (10) located in the multi-function handle (1), the door is transferred from the opening state to the fully locked state, and the mechanism assumes the configuration shown in FIG. 5, i.e. in the initial state. When the key is rotated in the lock cylinder (10), the crank lever (4) performs a pendulum movement and moves to the other side of the vertical axis (1a) so that the movement of its side surfaces (4b) pulls the opening transmitter (6) forward, causing it to move horizontally. During this movement of the opening transmitter (6), the guide projections (6a) force each of the teeth (7a) of the locking lever (7) so that the latter moves downward and allows you to change the configuration of the mechanism.

As seen in FIG. 6, in the case of a fully locked door, acting on the handle (11), an external driven element such as a butterfly (12) forces the transmission part (3) to move down, thus pulling the locking lever (7) and the opening transmitter (6). The driving surface (6b) of the opening transmitter (6) does not collide with the opening protrusion (5c) of the internal driven element (5), since it is on the other side of the vertical axis (1a) of the multi-function handle (1). Thus, the internal driven element (5) remains stationary, and does not actuate the valve of the device for quickly opening the emergency exit, keeping the door locked.

It should be noted that there is also a device for the supporting structure of the mechanism (2) to place a flexible pin (2a) with mounting pins (2b) on its free end so that a microswitch can be easily placed if an electrical signal is required. The properties of the flexible finger (2a) allow it to be pushed down in order to insert said microswitch; when this is done, the mounting studs (2b) hold him in the necessary position so that he cannot jump out. In addition, the crank arm (4) at its rear has a trigger protrusion (4a) designed to activate or deactivate any microswitch that can be inserted into the supporting structure of the mechanism (2) when the crank arm (4) moves out of locked position to the open, or vice versa.
