Description

Door drive with device Connection.

The invention concerns a drive for a revolving door according to the preamble of claim one.

A drive of this kind for a revolving door is known, for example, from DE-OS 32 02 966 C1. There is described a so-called electro-hydraulic door closer that has a compression spring as an energy accumulator to close the door and a hydraulic pump with electric motor to perform a motorized opening. The door is opened completely automatically, to which end the piston is displaced hydraulically with the help of the hydraulic pump under compression of the spring of the door closer and the closing process is then carried out as in a conventional hydraulic door closer by purely mechanical means under the action of the spring of the door closer. The door drive and the opener drive are integrated in a construction unit inside a housing. A drive constituted in this way is in practice coupled with a motion warning. When a person approaches the door, the opening of the door is induced through the door control system. In this case, the door is opened even if the person does not want to go through the door at all, but only stops in the immediate vicinity of the door.
same.

In document DE 43 23 150 A1 has been described another rotary door leaf drive. The door closer electrohydraulic represented consists of a call servo door closer that favors the motor a manual opening process of the door. To this end, the pressure of the hydraulic medium in the door closer adapts during the opening process to the respective momentary restoring force of the spring of the door closer. In this form of execution the door closer hydraulically damped and electrohydraulic actuation of the opener with electric motor and pump are integrated in a construction unit inside a housing attached to the sheet of the door or door frame. The connection and disconnection of the Hydraulic pump is effected through one or more sensors, such as, for example, a motion alarm, a switch on the sheet of the door or a turn transmitter in the door closer shaft. He connection process is initiated by a person who wishes to go through the door, that is, according to the sensor execution, automatically when the person approaches or by actuation of the switch.

Document DE 195 18 396 describes a drive for a revolving door that can be traveled on both sides, with an engine to open and close the blade rotating and with a sensor device that monitors both sides of the revolving door leaf and it is intended to activate the motor. TO For this purpose, the sensor device has a motion alarm on each side of the rotating blade, cooperating the warning of Wireless movement by radio with the engine on the side of the door leaf that is far from the engine. In a second embodiment is arranged only on the motor side of the door leaf a motion warning that monitors the position of the door latch. The form of execution is free of cable feeds on the door leaf and is especially suitable for protection doors fires.

Document DE 296 03 917 U1 describes a surveillance device for a door or a window. Leaf The door features a tiltable handle mounted on a hardware for the same and an embedded interlocking part attached to the handle to drive a lock slip. A first device sensor located in the handle hardware detects the drive of the shooter and then supplies a first signal of surveillance. A second is placed in the handle hardware sensor device that detects the open position of the door and then supplies a second surveillance signal. Both surveillance signals serve as warning signals for a central of vigilance. The sensor device consists of a switch magnetic or a vibrating tongue contact switch.

It is known from GB 17 942 a drive to open and close a door, which comprises a gear and an interleaved clutch to transmit movement from the drive to the axis of rotation of the door leaf, where a slide is formed so that the door remains in Open position for a certain period of time before closing. The drive is connected by a switch that is arranged in the frame of the door inside the closing plate and cooperating With the slip of the lock.

The fact that, after the connection, the drive opens for the moment completely with independence of the door handle operation and returns to close after a certain time of remaining in an open position. The drive is switched off only in the position Closing the door leaf. The people located in the area from the door could eventually be knocked down by door leaf moving.

The purpose of the invention consists in develop a door drive that makes a maneuver possible safe from said drive by the user and present an especially simple and reliable connection device for the engine.

The problem is solved according to the invention by the fact that the connection device to maneuver the engine electric is fixedly arranged on the door leaf or staring at a door handle arranged on the door leaf, performing the maneuver of the connection device by means of a relative movement of the door handle with respect to the leaf. Therefore, a person who wants to go through the door and grab for this the shooter of the same necessarily produces a signal of connection for the electric motor.

The preferred application field of the device of connection are door leaves with a lock zone, where the door handle is arranged in the area of the lock and / or through it, and where the door handle maneuvers the slip of the lock. The connection device has a microswitch, a vibrating reed switch or similar, which is arranged in such a way that it trips when maneuvering and deflecting the door handle. A fitting in the hardware is possible of the handle in the area of the vertical rotation axis of the handle, such as also in the turning area of the latch rod that crosses the door leaf to activate the lock slip.

Executions are also possible for doors without Lock zone or doorknob. In this case, the shooter of the door is fixed partially elastic or partially mobile on a socket screwed with the door leaf. To the contact with the door handle occurs, it is deflected by the forces that then appear, maneuvering said shooter a microswitch or similar arranged in the socket.

In another form of execution they may be also arranged electrically conductive areas in such a way that come into contact with each other during a maneuver and the consequent deflection of the door handle. In particular, some components of the door handle, such as the fixing socket, can also be construction electrically conductive

Other details of the invention are related in claims 2 to 25 subordinates.

The invention is explained in more detail in the figures. They show in these:

Figure 4, a representation of an example of alternative execution in cross section;

Figure 5, a representation of an example of modified execution in cross section; Y

Figure 6, a front elevation of a door swivel according to 1 with a door handle.

The example of execution of figure 1 shows a single-leaf revolving door in a building with a drive 3 upper door of conventional construction class. He door drive 3 consists of a hydraulic drive 3 of revolving door with which the door is opened by motor or with engine assistance and is closed with low hydraulic damping the action of a door closer spring. This drive is constituted as a hydraulically damped door closer with door closer spring, combined with a door opener drive electrohydraulic with electric motor and pump (without representation). The door closer and the opener operation are integrated in a construction unit inside a housing 31 that is fixed on leaf 1 of the door near the upper horizontal edge. He output shaft 32 of the rotary door drive 3 is jointly joined in rotation with a sliding arm 33 of a known way. The sliding arm 33 presents at its free end a sliding part as a guide element, which goes guided in the slide rail 34 arranged in the crossbar upper vertical of the stationary frame 2. The free end of the sliding arm 33 attacks here on sheet 1 outside the axis of rotation of said sheet 1.

However, executions are also possible in which door drive 3 is mounted on frame 2 and the slide rail 34 is mounted on sheet 1 of the door. Also, the force transmission linkage may be also configured as a scissor arm and supported with its end free on a stationary tilt bearing or on the blade.

In the exemplary embodiment of Figure 1 the sheet 1 of the door is pivotally articulated by its edge left vertical, through two door bolts, in the left vertical beam of frame 2. Drive 3 of the revolving door is connected to a power line of feeding and control 38 extending from the side left 37 of drive 3 of the revolving door to a power connection 12 in the door frame 2. Sheet 1 of the door has a lock zone 5 represented with a line of strokes carried by a lock slip 51. The drive of the Slip 51 of the lock is made in this case by pushing on the door handle 13 or pulling it.

Activation of door drive 3 to open the latter is carried out according to the invention by means of a sensor disposed in the area of the handle 13, which is connected to the door control system, not shown. The door opens as a result of the sensor maneuver, initially under the motor and pump action, which pumps hydraulic medium towards the circuit of the hydraulic door closer, so that move the piston and the spring of the door closer is tensioned. The process subsequent closure is done only by harnessing energy accumulated in the spring of the door closer. For the opening process You can also choose a so-called servo operation in which the sheet 1 of the door can be opened by hand under the assistance of motor with or without a reduced opening resistance offered by the door closer spring.

Figure 2 shows a detailed representation of the handles 13 of the door of figure 1 on both sides of the sheet 1 of the door, but having removed sheet 1 from the door. The two handles 13 are constructed as handles of bow and are mounted on the handle hardware 14 so that they can swing around a respective vertical axis. The Tilt direction of both handles 13 is directed at opposite direction of one with respect to another. The shooter 13 has to be maneuvered each time in the direction of opening of the door, that is, pulling on one side of the door and pushing on the other side of the door The two hardware 14 of the handles are joined through two bolted joints 16 that cross the sheet 1 of the door and, therefore, are fixed on this sheet 1. The latch rod 17 rotatably mounted around a horizontal axis between the two handle fittings 14 serves to maneuver slip 51 of the lock. The lock, no represented, may correspond in its structure to document DE 43 17 564 C2 or be structured like another conventional lock, such like the one written in brochure K87 5187 E of the Fritz firm Fuss GmbH & Co.

The handle 13 shown in figure 3 in section Transversal corresponds to that of Figures 1 and 2. It serves as a control for the slide 51 of the lock in the lock zone 5 of leaf 1 of the door and activation element for the door drive 3 shown in figure 1. The hardware of plate-shaped handle 14 carries on its upper ends and lower two respective horizontal wings 14b arranged parallel within walking distance of each other. Two 13th square pins are mounted on the upper and lower ends of the handle hardware 14 with the possibility of rotating around a vertical axis within wings 14b, said pins passing through wings 14. The quadrangular pins 13a serve as a possibility of fixing and shaft of rotation for the door handle 13. The handle hardware 14 It presents a central recess for the passage of the light bulb of the lock.

Between the two horizontal wings 14b at the end top of the arc is arranged a gear 15 that converts a spinning movement of the arch and the square pin 13a in a turning movement of the latch rod 17. This rod 17 it goes through the handle hardware 14 between the two wings 14b and it is like this attached to the gear 15. A turning movement of the rod 17 of the latch leads in a known way to a mechanical maneuver of the Slip 51 of the lock, after which the door can be opened. Between the two horizontal wings 14b at the lower end of the handle hardware 14, a reaction support 18 is attached in solidarity with rotation with the square pin 13a. A leg spring rests, on the one hand, on this support of reaction 18 and, on the other hand, on the handle 14 of the handle. He leg spring is tensioned when performing a maneuver of the handle 13 and produce a turn of the square pin 13a. Accumulated energy then on the leg spring it serves to move the archery after his maneuver returning him to the starting position original.

According to the invention, in this embodiment, found between the two horizontal wings 14b at the lower end of the hardware 14 a sensor arrangement which, when maneuvering mechanically the door handle 13 and take place the concomitant release of the lock slip 51, activate the door drive 3 at the same time to open this motorized door or with motor assistance. The disposition of sensor preferably consists of a microswitch 6 that is disposed between the two wings 14b and whose connection contact 61 penetrates the movement path of a connecting pin 62. The connecting pin 62 is arranged on the support of reaction 18 looking radially outward. When the bow shooter and when the concomitant turning movement occurs of the square pin 13a and the reaction support 18, the pin of connection 62 collides with connection contact 61 of the microswitch 6 and emits an electrical signal. The tour of necessary connection to emit the signal can be regulated by a corresponding positioning of the microswitch 6 and the connection pin 62. The connection signal is fed to the door drive 3, which then connects the motor to open the motor door or with motor assistance. The Transmission of the connection signal can be done both through of a cable feed inside the door leaf 1 as by radio The connection device according to the invention is suitable also for use in FR doors and RWS doors.

Figure 4 shows an example of execution alternative of a door handle 13 to generate a signal from activation for the electrical activation of a drive 3 of revolving door. Unlike the preceding form of execution, the door handle 13 does not work here to maneuver a slip of lock 51. A socket 4 is fixed with a screwed connection 16 on the leaf 1 of the door, the diameter of the socket 4 being more smaller than the inside diameter of the tubular puller 13. Socket 4 It also has a supplement 14 on which the shooter is mounted tubular 13. To this end, the handle is plugged from the front over the supplement 43 and fixed there with a cylindrical pin 44 which cross the handle 13. transversely between the socket 4 and the supplement 43 is an elastic body or an element of spring that, on the one hand, joins the socket 4 and the supplement 43 staring at each other, but that nonetheless allows some mobility of socket 4 and supplement 43 one with respect to other.

On the outer sides of socket 4 are arranged or integrated two microswitches 6. In assembled state, the end of the handle 13 turned towards the door is within walking distance distance from both the door and the connection contacts 61 of the microswitches 6. When the handle 13 is touched by a person who wants to go through the door, takes place, due to the forces produced, a corresponding deformation of the piece elastic intermediate. According to the direction of the deformation, the free end of the handle 13 thus comes into contact with one of the two microswitches 6, after which a signal of activation to door drive 3. Similarly to the example of previous execution, the motor door is then opened or favors the manual opening process in the situation of Servo operation.

A form of execution of this class without members Mechanical transmission is also suitable for producing in parallel with the activation of the motor an electrical maneuver of the Slip 51 of the lock. In principle, the signal of microswitch 6 can be used for any purpose.

In the example of execution similarly structured of figure 5 the microswitch 6 maneuver is not performs by means of a tilting movement of the handle 13, but by pushing the handle 13 in the direction of the leaf 1 of the door. In this embodiment, a socket 4 is also fixed on the leaf 1 of the door by means of a screwed connection 16. By the on the contrary, the supplement 43 embraces the socket 4 and is guided on this in displaceable form in axial direction. Between socket 4 and the supplement 13 is a saucer spring 45 or a spring of compression or an elastic body, as in the case of previous execution.

A guide pin 46 is anchored with its end 46a in supplement 43 and extends with its other end 46b to through a hole inside socket 4. A widened end 46b on the side of the guide pin socket 46 prevents slippage out of the drill. At the same time, it prevents the Supplement 43 slide down from socket 4. In the socket 4 a microswitch 6 is arranged below the end widened Pushing the door handle 13, the guide pin 45 is pressed against the connection contact 61 of the microswitch 6. This in turn controls drive 3 of the Door in the manner described above.

Finally, figure 6 shows a door swivel according to figure 1 with a conventional door handle instead of a swinging handle 13 of arc form to maneuver the slip 51 of the lock and to control the engine. The invention is independent of the configuration of the handle 13 of the door. It can be archery handles or doorknobs conventional. The handles 13 can be of tubular construction or in the form of a plate. The handles 13 may be constructed in tiltable, swivel or draggable or pushable shape in direction perpendicular to the plane of the door leaf.

The use of the device according to the invention It is not limited to the examples of execution represented. In instead of a microswitch 6, a vibrating reed switch or any other kind of contact connection 61. To further reduce the construction size, the part of the base connected to the door and supplement 43 connected to the handle 13 may also be electrically constructed conductive When a contact occurs, it originates then immediately an electrical signal that is used to activate the drive

In other modified execution examples versus to the execution examples represented in the figures the signal transmission from door handle 13 to drive 3 it is done wirelessly through a transmitter and a receiver. The emitter is fixedly arranged in sheet 1, preferably in the area of the door handle 13 or the door handle 13. In a alternative execution example the fixed arrangement of the issuer It can also be done in the fence 2 of the door.

The receiver is preferably arranged in the area of the drive 3, preferably in or next to the housing 31 of the drive.

The power supply to the emitter and / or the receiver can be made through one or more accumulators. He accumulator to power the transmitter is arranged fixed on the sheet 1, preferably fixed on the door handle 13, being able to be arranged this accumulator in the emitter zone as a constructive unit with the transmitter.

In all the examples of execution the signal of activation can be configured as a pulse, preferably a single impulse, or as a permanent signal.

The drive can be connected during as long as the activation signal is applied, that is to say releasing the door handle or similar interrupts the process of the opening and / or closing of the motor revolving door leaf or with motor assistance or then only the process closing until the closed position is done by motor or with motor assistance or automatically through a spring door closer. However, as an alternative, it may be provided also that the process of opening and / or closing the sheet of revolving door with motor or with motor assistance be put in marching by the activation signal, preferably by a pulse, and the door leaf then perform motor or automatically An opening movement / full closing movement.
