Description

Control handle with entry monitoring system

Technical Field

The present invention relates to a control handle, such as a door handle or a window handle.

Background

A door or window usually functions as a closing mechanism for closing a building opening in the form of a door opening or a window opening, to prevent foreign objects from entering from the outside, or to prevent weather effects. If the closure mechanism is not locked, the closure mechanism can be operated from the inside by means of the control handle. It is known to design the control handle in lockable mode if the window handle on the inside of the window is to be locked.

Mechanical keys can be inconvenient to use, particularly for larger buildings, if not all windows can be opened at all times. The associated window handle must be locked separately and opened with its key. The installation of an electronic locking system operated by a transponder or a key card can be complicated because the reading unit for reading the transponder data must always be powered on.

A need has arisen to provide a control handle, particularly in the form of a window handle or door handle, which can be easily and conveniently retrofitted, which can be flexibly and conveniently locked without the use of a mechanical key.

Disclosure of Invention

The invention proposes a control handle for fixing to a window, comprising a locking mechanism for locking and unlocking the control handle. There is also a lock control system connected to the locking mechanism for controlling the locking mechanism. The control handle is characterized in that it is an insert connected to the locking control system. The locking control system is designed such that when the insert is actuated by the control unit, the control handle is to be interrogated for its opening authorization and, if this is the case, the control locking mechanism is unlocked.

A control handle is understood to mean a device for opening and closing a door or window. It is particularly useful for the present invention to provide a member that is movable by the user, which member can be locked by a locking mechanism. This means that the control handle is locked at least in one position and is locked before further movement. Thus, the control handle may particularly relate to a movable window lock. Of course, the control handle may also be used for the door.

The locking mechanism is a mechanical device configured to lock or unlock the control handle. Various solutions are known for this function. These solutions have in common that a locking bar or similar movable means is placed and moved from the unlocked position into the locked position or vice versa when required. By this movement, the operational capability of the elements of the control handle can be locked or released. The specific structure of the locking mechanism depends to a large extent on the installation space present, the element to be locked and the expected force. In order to be able to operate such a locking mechanism, a drive unit is also required. The motor is particularly suitable for this purpose.

To control the locking mechanism, a locking control system is used. The control system is designed in particular as an electronic device which is connected to the drive unit. Thus, the locking control system may cause the locking mechanism to execute a movement. By supplying power to the drive unit, the drive unit can be put into operation to move the mechanical element.

One feature of the control handle of the present invention is that it is an insert that is connected to the locking control system. The insert may comprise, for example, a push button, a toggle switch, or another mechanical, electrical, or combination sensor. It initiates a query open rights process if necessary. The insert can also be designed to be contactless.

In the present invention, the management unit is a device that can provide information on the opening authority. For this purpose, the management unit can have a memory for storing identifiers or other identification data of a plurality of control handles and associating them with preset or predefined opening rights. Wherein the opening rights are not necessarily static but can be modified regularly, in particular when used in a home control system. Thus, by querying the administration unit for the opening right, the current opening right can be checked and reported to the lock control system.

The locking control system may maintain the locking mechanism in a locked state or actively unlock the locking mechanism based on the requested opening authority.

Therefore, the control handle according to the present invention is a mechanism that is convenient to use, and a user can restrict operations according to an externally designated opening authority. There is no need to control the handle, for example by means of a key (mechanical or electronic). Modern control systems for buildings can make the operation very convenient and change the details of the rights.

The management unit may be arranged outside the control handle, and the control handle may comprise a communication device for connecting to the management unit. The management unit may be, for example, a component of a building management system. Such devices are often located in a central space together with the switching and control of a bus system. This has the advantage that the control handle has a communication device which can be connected to the management unit. Communication devices with relatively large transmission distances, but with low power consumption, seem to make sense. However, the required data rate is very low. The communication device may in particular be wireless, which may simplify the rear fitting of the control handle.

Preferably, at least one first sensor is provided for detecting the position of the handle member. At least the first sensor may not necessarily be able to determine the exact position of the handle member. It is sufficient that it is able to detect the individual discrete operating positions. Feedback, in particular to the management unit, can thus be made in this way. If it is assumed that the position of the handle is actually associated with the opening state of the associated window or door, the opening state can be detected without equipping the window or door with a corresponding sensor.

In an advantageous embodiment, the at least first sensor has at least one reed sensor arrangement connected to the handle part and the stationary part, which arrangement has at least one reed magnet and at least one reed sensor. This is particularly advantageous for contactless detection of states. This increases the reliability of the sensor device. This is advantageous in particular for arrangements of handles which may be handled somewhat crudely.

The at least one first sensor may have a two reed contact arrangement with two reed magnets and two reed sensors to identify three different positions of the handle portion. Control handles, in particular for windows, usually allow three positions, corresponding to the window being closed, the window being fully open and tilted, respectively. Thus, a total of three identifiable positions can be determined using two reed magnets. It should be noted in this connection that the two magnets preferably have different field strengths and that the reed sensors do not have the same detection plane.

The lock control system may preferably be constructed such that: the locking structure completes the locking after the handle portion is moved to the closed position. This may relate to, for example, a point in time of leaving a room, for example at the end of a working day in an office building. In particular, since the operating frequency of a window is generally not as high as that of a door, it may be designed such that: if the window is not actively opened, it is always in a locked state.

It is advantageous if the locking mechanism has a locking bar and the locking bar is movable to selectively engage an element connected to the handle member between at least two longitudinally spaced positions. The handle is generally coupled to a drive shaft, which is located within a pin bearing. The drive shaft or another drive shaft coupled thereto may extend into a window mechanism or a door mechanism. The locking bar moves in a rotatable element which is directly mechanically coupled to the window or door mechanism, enabling a reliable locking of the control handle and thus the window or door.

The locking mechanism may include a gear box having at least two gears, one of the gears having a cam radially spaced from the axis of rotation of the respective gear, the cam being connected to the locking bar to move the locking bar. The use of a gearbox with gears can produce a higher torque and thus a higher moving force for the locking bar. The motor can be made very small and in particular be arranged with high speed. In addition, gearboxes with gears are technically mature and can produce high forces or torques even if they are made in very small form.

The handle part can preferably be connected to a rotatably mounted bearing element which has a radial cutout in a circumferential section, into which a locking lever of the locking mechanism for blocking the rotation of the bearing element can be inserted. The bearing member may support a drive shaft that is directly connected to the handle. The bearing element can be an integral part of the pin bearing. By inserting the locking lever into the cutout, the bearing member can be effectively prevented from rotating.

The width of the radial cut-out may preferably also exceed the width of the locking lever which can be inserted into the radial cut-out. Due to the large width of the cut-out, it is not always necessary to align the handle portion very precisely when manipulating the control handle. The locking mechanism allows the handle to be positioned inaccurately without losing its functionality.

The bearing piece can be used in particular for supporting parts of the bearing of the drive shaft. This has been explained briefly above. The bearing member may form a pin bearing similar to a ball bearing or the like surrounding the bearing member.

In particular, it is preferred to couple the locking lever to the locking mechanism at least in the direction of movement of the locking mechanism via a spring. The direction of movement may particularly relate to a movement from a locked position to an unlocked position. If the user asks for the opening right and moves the control handle before the actual unlocking starts, the locking lever may tilt. In order to protect the locking mechanism, a spring can be used as coupling element at least in this direction of movement. The locking mechanism may then cause the spring to compress, creating a force on the locking bar, which then moves the locking bar when it is no longer tilted. This can effectively protect the locking mechanism from injury with the user.

Furthermore, at least one second sensor is preferably provided, which is designed to detect the locked state. Therefore, when accurate feedback on the current position is known, the lock control system can accurately control the driving device. The detected position may also be communicated to the management unit.

In an advantageous embodiment, the locking control system is switched off after each activation. In particular, for control handles that can be retrofitted, it is possible to arrange for them to be driven by batteries. For technical devices that operate for long periods of time, such as smoke alarms, there are very durable lithium-based batteries. Such batteries may also be used in the control handle to which the present invention relates. With advantageous energy management, the running time can be expected to be up to several years, depending on the number of operations.

This may also include that the locking control system is first activated by operating the insert.

Detailed Description

Fig. 1 shows a brake handle 2 in a simplified exploded view, wherein the main components of the brake handle 2 are visible. First, a bearing unit 4 can be seen, which has a pin bearing 6 for supporting a first bolt 8 and a second bolt 10. In the example both

pins

8 and 10 are designed as squares and function to introduce and transmit torque.

Furthermore, a locking unit 12 is shown, which locking unit 12 can be integrated as a separate module on the storage unit 4. For this purpose, the bearing unit 4 has an interface surface 14, which is in engagement with the locking unit 12 at a fastening portion 16. For locking the locking unit 12 in the interface surface 14, two oppositely situated pressure plates 18 are shown by way of example, whose outer extremities are provided with lugs 20 as positioning means which can engage in corresponding lateral sections of locking openings 22 of the bearing unit 4.

The latch 24 mechanically inhibits movement of the first bolt 8 which extends from the lock unit 16 as will be described in further detail below. The locking unit 16 furthermore has an insert 26, which insert 26 is provided with an input device 28 in the form of a trigger button. For this purpose the locking unit 16 can be screwed to the bearing unit 4 using threaded bolts 28 in the schematic drawing. For this purpose, the bearing unit 16 has a through-hole in the drawing, while the bearing unit 4 has a threaded hole, not shown here.

To form a closed control handle 2, a housing 34 is provided having a first section 36 for passing through the first bolt 8. The handle member 38 is finally secured thereto, which makes it possible for the user to move the second bolt 10, which second bolt 10 can be mechanically connected to a window or door.

In fig. 2, the bearing unit 4 and the locking unit 16 are separated from each other and shown from another angle. Here, a latching hole 40 is shown at a point directed toward the engagement surface 14 of the pin bearing 6, through which opening the latch 24 can be inserted into the pin bearing 6. A part rotatably mounted in the pin bearing 6 can thus be locked or released as required by means of the latch 24, which part will be described in further detail below. Whereby the locking unit 16 is able to lock the movement of the handle portion 38 by means of the latch 24. For the sake of completeness, in this figure, a threaded hole 42 can be seen in the interface surface 14, which threaded hole 42 serves for the installation of the above-mentioned threaded bolt 30 and serves for fixing the locking unit 16.

Fig. 3 shows the locking unit 16 in fig. 1 in 3D, but slightly enlarged. The locking unit 16 has a housing 44 which houses the mechanical parts of the locking unit itself and is enclosed by a housing cover plate 45. The detent button 28 is connected to a latch control system, not shown here. Here too, an external control unit is not shown, which has access to the right to open the brake handle 2. If there is an opening authorization, the locking unit 16 is controlled to be unlocked, that is to say the latch 24 in the extended state is retracted into the locking unit 16 here. More details are set forth in the following description of the figures.

Fig. 4 again shows the locking unit 16 and the bearing 4 in an integrated state from another angle. It is shown that the locking device 20 is locked in the opening 22 and the screw 30 on the picture is inserted into the hole 32. This results in a complete individual that can be fixed to a door or window via the mounting holes 46 and 48 (see fig. 2). In this case the locking unit 16 is fixed to the bearing 6. The control handle 2 of the present invention does not have to be fixed using holes in the window or door.

In fig. 5a and 5b a partial section of the bearing 6 is shown. The bearing element 50 is held in the recess 52 by a rotationally fixed bolt 8 and can be screwed into the bearing 6. The plug 10 which can be inserted into the recess 52 from the other side is not shown here (see fig. 4).

To control the locking of the handle 2, a radial cut 54 is provided in the bearing part 50, in which the locking pin 24 can be displaced longitudinally along the cut 55. The locking pin 24 fits completely flush with the radial cut surface 54 in fig. 5 a. In fig. 5b, the locking pin 24 is moved downwardly to slide out of the radial cut 54 so that the bearing assembly is in a rotatable condition. In fig. 5b, the bearing member 50 is non-rotatable, so in this case the user is unable to rotate the handle 38 in fig. 1.

In fig. 6a and 6, another plan view of the bearing 6 is shown, in which case the cut surface 54 can be shown more precisely. For example, the radial cut 54 does not extend from the inside to the outside with a uniform width, but rather extends outward through an outward opening angle α. This is chosen so that the bearing member 50 and handle 38 need not be held in the closed position precisely, but will have a slight angle of inclination so that the cut surface 54 can slide in. The locking mechanism may therefore allow imprecise operation of the handle.

Fig. 7 shows an exploded view of all the elements of the locking mechanism 16. First temporarily, the lock control system 56 is assembled from a number of components on a circuit board. The system is mounted on a circuit board carrier 58 that can be screwed into the housing 44. The housing 44 may be locked behind with a back plate 59 and a locking mechanism 60 may also be hidden behind.

The locking mechanism 60 houses a gear assembly 62 comprising a gear 64 and a gear 66.

Gears

64 and 66 are engaged with each other as shown in the other figures and are associated with latch 24. On the back of the gear 64 is a cam which is embedded in a base 68 associated with the latch 24. The small electric motor for operating the gear transmission 62 cannot be shown in fig. 7.

The insert 70 is mounted in the form of a key on the lock control system 56. As shown in fig. 7, the operation button 28 is directly placed on the operation unit 16, is connected to the lower insert 70, and can control the pressing of the key 70.

Inset 8 is an enlarged depiction of the locking mechanism 60. It is clear that there is a position base 68 and a movable latch associated with a spring 72, from which a latch 74 can be pushed in or ejected.

Fig. 9 and 10 are each an exploded view of the locking mechanism for better depiction of each component. Depicted on the front of inset 9 is the back of each member of inset 10. A latch 74 is mounted on position base 68 and indicates the association of spring 72 with a pin 76. The spring bears against the lower edge of the seat 68, causing an upward movement, that is to say the direction of the detent 24.

Inset 10 shows an eccentric cam 82 on gear 64 that contacts a lower contact surface 84 of position base 68 and an upper contact surface of latch 74. The first gear wheel 64 can cause the latch 74 to be moved in a first direction or to be positioned in a base-flipped direction by the cam 82. The force of spring 72 acts on the position base by moving latch 74 so that position base 68 follows latch 74. Moving the latch 24 in both directions of movement of the position base 68 via the latch linkage 86 prevents damage to the locking mechanism 60 by the one-way indirect linkage between the first gear 64 and the latch 24 when the handle portion 38 is operated, although the latch or disconnect is not yet fully latched.

The illustrations 11a to 11c show one possible movement process. The first gear 64 is shown covered and only the cam 82 is visible, and the latch 24 is shown in a retracted position in figure 11 a. The locking pin 24 is thus in the unlocked position. The cam 82 is therefore also in the braking position of the bearing arrangement. By rotating the first gear wheel 64 the cam 82 is moved towards the bearing device 4, causing the cam 82 to act on the lower contact surface 84 of the position base. The position base 68 is thus moved towards the bearing arrangement 4 so that the locking pin 24 can be brought up against the bearing member (not shown here).

The unlocking action is now performed and the locking pin 24 must be moved from this position back to the position shown in the inset 11 a. Depicted in the insets 11b and 11 c. The first gear 64 will continue to rotate. Of course, at this point in time, the handle portion 38 is already in motion and the detent 24 is placed over the edge of the radial opening 54. A simple retraction of the locking pin 24 is no longer possible. The first gear 64 will continue to drive and gear 64 and gear 66 will engage. To prevent overloading of the

gears

64 and 66, the cam 82 in this case can be pressed away from the bearing arrangement away from the upper contact face of the detent 74. In that position the seat 68 cannot follow because the position edge, the spring 72 will be compressed in that position, and once the detent 24 leaves its edge, the seat 68 will move away as the user moves the handle portion 38 back and forth, through the compression spring 72 and then away from the bearing means to the unlocked position (see inset 11 c). The lock pin 24 is unlocked from the radial port 54 and the bearing member.

This correlation involves the cams only rotating in one direction. Whereby the resultant movement of the position base 68 adjusts the locked position or unlocks the lock in accordance with the cam 82.

Inset fig. 12a and 12b depict the locking control system 56 as being relatively movable in position with respect to the base 68. By installing three

position sensors

86a,86b,86c, previously referred to as (second sensors), in appropriate locations on the locking control system 68, the current position of the positional base 68 can be located. The

second sensors

86a,86b and 86c, which are another form of limit switches, may in this example show at least three discrete positions. This directly results in the locking control system 56 regarding the current locked state and the possibility of controlling the motor and gear drive.

The inset 12a position the base 68 is in position to the bearing arrangement 4 so that the two

sensors

86a and 86c are in an unactuated free state. In particular, the free state second sensor 86a is described below, the operating handle 2 being locked. While cam 82 is in the unlocked position, latch 74 is in the second sensor coverage. An unlocking action should be performed, as should the position of the lower cam 82 and the motor at the position where the latch 74 is open.

The inset 12b, in contrast, is covered by all of the

second sensors

86a,86b, and 86c, which can be closed thereby, leaving the cam 82 and the lock pin 24 in the unlocked position. The lock control system 56 is therefore able to precisely control the motor and the lock mechanism 60 in this case and additionally to obtain the state of the lock mechanism.

The inset fig. 13a to 13c show each of the different states of the locking control system 56. Inset 13a does not depict the locking feature in order to be able to show an overview of the location of the

second sensors

86a,86b and 86 c.

The inset 13b is that all of the

second sensors

86a,86b, and 86c are uncovered and must be able to perform a productive latch. To latch, the motor drive gear 64 and gear 66 are closed and the lockout control system may be closed.

The base 68 operates in the opposite position to that of the inset 13c, and all of the

second sensors

86a,86b and 86c are covered and must be able to perform unlocking. If an unlocked state is desired, the motor is also turned off.

The previously depicted lock control system 56 may be connected to additional administrative units in accordance with the control minimum input unit 70 in order to retrieve open rights. The locking control system 56 in this regard is a communication device. Integrated circuits can also be included. The locking control system 56 communicates the status of the locking mechanism to the administrative unit via the communication device in this case.

In addition to this, the lock mechanism 60 also focuses on the positional state of the grip portion 38. Knowledge in this respect will also make use of delayed closing of the operating handle 2, in particular in sensitive areas. The inset fig. 14a to 14d show the bearing member 50 with two

different reed magnets

88 and 90 mounted in two opposite horizontal positions. The relative positions of the

reed magnets

88 and 90 to lock the operating system are changed by rotation of the handle portion 38. The reed magnet 88 is a little larger and has a larger magnetic field strength than the reed magnet 90.

Corresponding reed sensors

92 and 94, mounted on the back of the lock control system 56, can also house an array of reed sensors.

Inset 14b shows magnet 90 mounted closer to the lock control system, with reed 94 closer to handle portion 38 closed and gap sensor 92 open. This switch combination can illustrate the lock control system 56 state and the handle portion 38 can be in a vertically downward position, typically for closing a window. The closed position can be detected more accurately due to the small magnetic field.

The inset 14c is for the bearing member 50 to be twisted 90 degrees so that the

reed magnets

94 and 94 are not activated. This state is to present the handle portion 38 horizontally open.

Insert 14d the reed magnet 88 with the stronger magnetic field, and nearby

reed magnet sensors

92 and 94, which can be triggered based on the larger magnetic field, this condition can be used as a third of the handle portion for the necessary angled opening window, as illustrated (see also insert 15 a).

The

reed magnets

88 and 90 are also positioned in other and particular inverted installations and logic changes are made to the lockout control system 56 in response thereto. A larger magnet 88 is mounted closer to the lock control system like fig. 14b to close the reed sensor 94 closer to the grip portion 38, keeping the spacing sensor 92 open. This switch combination can illustrate the lock control system 56 state and the handle portion 38 can be in a vertically downward position, typically for closing a window. The handle portion 38 can be rotated to a 180 degree position to match the angled window to adjust to a smaller magnet closer to the lock control system 57.

Inset figures 15a,15b and 15c show a complete cross-sectional view of the simulated control handle. Insert 15a shows the third position of the handle portion 38, which is a tilt-open window arrangement. The locking pin 24 is in the unlocked position. Fig. 15b also shows the locking pin 24 in the unlocked position, with the radial opening 54 open, and with the bearing member 50 providing access to the handle portion 38. Fig. 15c shows the locking pin in the locked position, with the bearing member 50 and handle portion 38 not being movable within the radial opening.

Finally, inset 16 shows the assembled control handle 2 depicted stereoscopically. A communication device 98 is shown diagrammatically, with which the management unit can communicate. The control handle 2 can be operated by the control of the minimum input unit 26, and the communication device retrieves the opening authority of the management unit 96 and unlocks the lock if necessary.

The present invention is not limited to the above structural form but may be modified into various forms.

The markings and advantages which appear from the description and drawings, including details of construction, arrangement of parts and process steps, are all indispensable for the respective combination according to the invention.
