Sweden-Sverige (SE) 3232/71 (71) Paul Herbert Brändström, Box 2269, 826 00 Söderhamn, Sweden-Sverige (SE) (72) Paul Herbert Brändström, Söderhamn, Tage Lennart Äsvärd, Spanga,

The present invention relates to a door and similar device for doors and the like which allows the door to be opened by acting directly on the handle using a lock fitted with a keyhole on one side of the door other than the lock pattern, and comprising, in the opening direction of the door, by twisting or pressing an actuating lock torsion device having at least one helical groove and pressing in the opening direction of the door a movable pin carrier having at least one pin gripped with the groove adapted to twist the groove or individual to which the groove is fitted or vice versa, which torsional movement enters the lock to open the door.

The invention relates to a combined handle and button intended for use with standard standard door locks.

German patent publication 233 757 discloses a door IuKlocking device, the handle or actuating member of which is a locking device torsion device which is actuated by pressing it in the opening direction of the door. The torsion device comprises a helical groove and a pin carrier movable in the opening direction of the door by pressing 2 58196 pins in grip with the groove. Since said handle is pushed in in the opening direction of the door, the part to which the groove is fitted is twisted. This torsional movement is transferred to the lock tongues to open the door.

Doors fitted with such a locking device may be opened and closed only from the other side of the door. In addition, this device must first be rendered inoperable, since pulling the handle otherwise causes the tongues to protrude into the locking position and thus the door cannot be closed.

It is a very common practice to equip doors with some kind of locks so that the door can be kept closed or opened if desired. Opening can e.g. happen only by using the right key or by pressing the door rib, handle or turning the button, or a combination of the above.

In this case, one drawback is that at least one hand or elbow must be available to open the door. In certain cases, it is not possible, not possible or not to install a push-down rib, which is why you are completely forced to turn the handle with one hand.

This is the case, for example, in the doors of electrical switchboards, which are opened on the outside with a key and which must be able to be opened quickly from the inside in a simple manner. Switchgear doors must always be kept closed in accordance with current regulations, including during work, such as inspections, repairs, troubleshooting, etc. However, in such cases there have been accidents where an electrician or other person in the switchgear has come into contact with live components. fire damage and in which case he has not been able to survive out of the switchgear himself, which is necessary due to the formation of toxic gases in such short circuits. The aggravating factor is that in such accidents, the person in question easily falls into the power of panic and rushes blindly against the door without getting it open, which can further aggravate the feeling of panic. Another example is the furnishing of homes for the disabled or disabled, where it is not known in advance in what way the future homeowner is disabled or disabled, but nevertheless, for cost or other reasons, efforts must be made to find as many standard closures as possible. Among other things, the door must be locked and thus also the doors can be closed and especially opened as independently of the degree of disability or inconvenience as possible.

The doors of other doors, such as cinemas, meeting rooms, meeting rooms, study rooms and other rooms that can be quickly emptied in certain circumstances, such as fire or the like, must also be equipped with door lock actuators that are panic-proof and disabled-friendly.

German patent publication 33429 discloses a door lock which can be opened on one side either by twisting or pressing a knob. Lm. during pressing, the pin in the first groove prevents the threaded spindle from turning. The threads of the spindle are in contact with the rotor, which rotates the weight - around the center of rotation, whereby the tongue of the lock is retracted. The same lock can also be opened exclusively by twisting the knob, causing the pin to move into another groove. The disadvantage of this lock is manifested in the situation _ where the knob is pressed lightly and then an attempt is made to open the door by turning the knob, in which case it cannot be opened. This is a very big drawback in panic situations, for example. The situation is exactly the same if the knob is first twisted slightly and then pressed.

The object of the invention is that the lock and with it the door must be able to be opened by pressing the actuating member on the elbow, hip, shoulder, back, knee or the like, it is on practically any part of the body, without the need to perform a gripping movement. And on the other side of the handle body, or the effect may not differ from the normal use of too much conventional practice door is opened.

The device according to the invention is characterized in that the groove is arranged in a hollow cylinder with a pin projecting centrally from one end thereof, intended to co-operate with a standard door type lock, so that the pin carrier can move in the hollow cylinder and has an axially projecting an shaft or the like for securing the handle of the lock and a non-rotating guide member arranged around the hollow cylinder, having at least one abutment extending substantially parallel to the opening direction of the door for a radially outwardly projecting outer end of the pin which allows the door to be opened by pressing in and twisting and twisting the lock formula k.

According to a particular embodiment in which the lock is a standard type cylinder lock, it is proposed that the control member be non-rotatably attachable to the cylinder lock and that the pin be adapted to co-operate with the cylinder lock rower. Such a structure can be very easily subsequently installed on doors with a cylindrical appearance. To this end, the existing handle or door handle and the plate-like lock fitting are removed. The device according to the invention is then fastened with the same screws, after which the plate-shaped lock fitting and external actuator or the previously removed knob or door handle is secured in place.The only detail that may need to be fitted is a pin that works with the cylinder lock rower, which may have a different shape in different lock products.

According to another embodiment, it is proposed that the abutment edge of the guide member for the radially projecting outer end of the pin forms a guide groove extending axially in the opening direction of the door and a free groove extending outside the rest position of the pin in the abutment direction to twist the door handle. In this case, preferably, the axial guide groove or the free groove in the guide member has an outer width or length corresponding to the torque angle required for the lock channel to be twisted with the lock key corresponding to the opening.

A particularly strong locking device is obtained if the two abutment edges or the corresponding guide grooves, possibly together with the free groove, are arranged in the counter member and are opposite each other and that the pin of the pin carrier protrudes through and out of the two opposite groove grooves at both ends.

In order to be able to use the device according to the invention for both left and right opening doors, it is further proposed that a free groove is arranged at both ends of each guide groove open towards the nearest end surface of the guide member and that the three grooves together form a uniform U-shaped groove.

It is further proposed that the pin carrier or the grooved part is loaded in the opening direction of the door or by a spring acting against the opening direction, which returns the handle to the open position when the handle is actuated in the opening direction.

Additional features and details of the invention will become apparent from the following description of an embodiment of the invention in connection with the accompanying drawing. Fig. 1 shows a cross-section of a door with a device according to the invention mounted on a cylinder lock, Fig. 2 shows an embodiment of the device according to the invention in side view and partially sectioned, Fig. 3 illustrates a hollow cylinder according to the embodiment shown turned 50 ° with respect to Fig. 2, Fig. 4 axially device, and a diagram £> schematically shows a part of the door in which the impact member has been moved from the lock.

Fig. 1 shows a door 1 in which a lock of standard manufacture 2 is installed. A special control member 4 is mounted between the door and the lock-shaped lock fitting 3. The door is opened in the figure with a key on the left and a handle, i.e. an external actuator 5, on the right. -on clockwise or pressed in horizontally to open the door. All the details shown in Fig. 1 are standard details and ordinary, commercially available except for the control element 4 and the special device according to the invention built into it.

Figure 2 shows in more detail an embodiment of the built-in mechanism of the control member 4. The hollow cylinder b resembling a goblet is provided at its other end surface with an axially projecting, square pin 7 intended to engage with a so-called rower of the door lock, which is not shown. A high pitch rail 8 is machined in the casing of the hollow cylinder 6. This pitch can be either constant or, according to an embodiment of the invention, increase in the direction towards the pin 7. In the latter case, the intention is to compensate for the increasing resistance with increasing printing. Adhering to the track 8 are two pins 1U projecting radially from the cylindrical pin carrier 9. The outer end 10 'of this pin is radially outside the circuit ~ of the hollow cylinder 6. The pin carrier 9 goes to the right of the axially projecting shaft 11, to which the external action member 5 is suitably attached.

The hollow cylinder 6 is surrounded by a fixed guide member 4. In the guide member 4, in Fig. 3, a stop edge 12 for the outer end 10 'of the pin 10 is marked with a broken line. This counter edge 12 can be formed in various ways. This exemplary embodiment will become apparent from Figures 2 and 4, in which the abutment edge 12 is formed by the second side wall of the guide track 12 ', in Figure 4, left. The guide track 12 'can be either substantially at right angles thereto, on the other side - in Figure 4, clockwise - Deep pin 10 from a rest position vapaaraiteesta 12 "or formed over a width which corresponds to a free track 12 shown in Figure 4," the length of the drawing plane. The guide member 4 is non-rotatably fastened to the door from the bores 16 therein and from the fitting 3 and the screws 58196 mounted on the door.

The operation of the device is as follows.

When the lock lever 5 is rotated in the direction of the arrow Py, this rotational movement is transmitted to the shaft 11, nastankantajalla 9, a pin 10, the track 8, onttosylinterillä 6 and 7 of the lock pin as a square rower. The outer end 10 'of the pin then rises off the abutment edge 12 and enters the free track 12 ". This path of operation can be compared to the conventional mode of operation.

Another but functionally equivalent way of working is achieved when the lock lever 5 is pressed in the arrow P direction. Then the shaft 11 and with it the pin carrier 9 with its pins 10 protrude to the left in the hollow cylinder b in Fig. 2 against the force of the spring 13 mounted inside the hollow cylinder 6. In this case, the pin 10 slides along the track 8 in the hollow cylinder 6. At the abutment edge 12, it is on the left side wall of the guide track 12 '(Fig. H), however, the pin 10 at its outer end 10 * is prevented from following the rise of the track 8. Instead, the hollow cylinder b pivots and with it a pin 7 and a door lock rower and a lock latch 16, which retracts and opens the door. This pressing against the lock handle 5, marked with an arrow P, can be performed on virtually any part of the body, with a carried object, a carriage or the like. In this case, it is important that no gripping movement needs to be performed. For example, a person struck by a panic can simply throw himself against the organ of influence and thus open the door.

Figure 5 again shows an alternative embodiment in which the device according to the invention is not attached to the door in the immediate vicinity of the lock, but is placed closer to the center.

The hollow cylinder 6 is then connected to an arm 1 * +, at one free end of which a support rod 15 is articulated, which in turn is articulated to the second arm 14 ', which acts on the rower of the lock.
