Abstract

The invention relates to a device (10) for simplifying the adjustment of a rotatable adjusting element (204) of a furniture fitting (200), wherein the device (10) can be connected to a screw tool (104).

Description

[0001] The invention relates to a device according to the preamble of patent claim 1, a system according to the preamble of patent claim 12, a method according to the preamble of patent claim 13 and a computer program product according to the preamble of patent claim 16.

[0002] To ensure the proper functioning of various pieces of furniture, such as cabinets and drawers with different opening options and fitting systems, it is necessary for the fittings to be precisely adjusted. Typically, the furniture fittings can be adjusted via a rotating adjustment element using a screw tool. This allows, for example, a desired load-bearing capacity, opening angle, counter-torque, and / or stop to be individually adjusted to the respective piece of furniture and adapted to the needs of the furniture operator.

[0003] In practice, however, it has been found that manually adjusting furniture fittings by means of rotating adjustment elements with a screwing tool by an operator is often imprecise and unreliable and that a passable result is often only achieved after a long adjustment process or, in some cases, an unsatisfactory adjustment cannot be achieved at all.

[0004] The object underlying the invention is therefore to simplify and improve the adjustment of a rotatable adjusting member of a furniture fitting.

[0005] The object is achieved with a device of the type mentioned at the outset, wherein the device comprises a sensory revolution counting device with at least one sensory detection device for detecting sensor data relating to the revolutions of the screwing tool, wherein the sensory detection device is configured to detect the sensor data relating to the revolutions of the screwing tool independently of a fixed reference point.

[0006] Because the device comprises a sensory revolution counting device with at least one sensory detection device for detecting sensor data relating to the revolutions of the screwing tool, when adjusting a furniture fitting via a rotatable adjustment member by means of a screwing tool, the number of revolutions the screwing tool performs when adjusting the furniture fitting can be detected, so that an operator of the device can know at any time during the adjustment of the furniture fitting how many revolutions the screwing tool and thus the rotatable adjustment member of the furniture fitting has already performed and / or when an intended number of revolutions has been reached.By knowing the exact number of revolutions of the screwing tool, especially in combination with the knowledge of a change in the setting of the furniture fitting that corresponds to the number of revolutions, it is possible to adjust the furniture fitting quickly, precisely and reliably as desired.

[0007] Because the sensory detection device is capable of detecting the sensor data relating to the rotations of the screwing tool independently of a fixed reference point, the device is suitable for simplifying the adjustment of a rotatable adjusting element of a furniture fitting individually on many different screwing tools suitable for adjusting furniture fittings, regardless of the selected screwing tool, and for detecting sensor data relating to the rotations of the screwing tool. This makes the device suitable for retrofitting any screwing tool and can therefore be used to adjust any rotatable adjusting element.

[0008] The adjustment member of the furniture fitting is preferably designed as an adjustment screw. The screwing tool preferably comprises a rotary blade that is permanently connected to the screwing tool or a reversibly replaceable, non-destructively replaceable rotary blade that can be connected to the screwing tool. The rotary blade is preferably designed to rotate the adjustment member designed as an adjustment screw to adjust the furniture fitting. The device and / or the sensor-based revolution counter device preferably comprises an electrical energy storage device, for example one or more replaceable batteries or one or more rechargeable batteries for supplying power to the revolution counter device. The screwing tool can be designed as a screwdriver, in particular as a hand screwdriver, and / or as a pneumatic or electric screwing machine, in particular as a cordless screwdriver.The screwing tool can also be designed as a ratchet, wrench, socket wrench, and / or torque wrench. Furthermore, the screwing tool can be designed as a screwdriver insert, in particular as a bit, and / or as a hex key. Furthermore, the screwing tool can be designed as a bit holder for holding interchangeable bits with different rotary blades or as a rotary blade holder with a non-interchangeable rotary blade.

[0009] The rotary blade can be designed as a special tool for adjusting a furniture fitting, in particular with a non-standardized rotary blade, wherein the rotary blade can, for example, have a shape that specifically corresponds to the adjustment element of the furniture fitting, in particular to an adjustment element designed as an adjustment screw. The rotary blade can also be designed as a standardized rotary blade, for example as a Phillips-head or slot-shaped rotary blade.

Measuring the rotations of the screwdriving tool using a gyroscope sensor is particularly advantageous because a gyroscope sensor can detect the revolutions without relying on a fixed reference point or reference object. Therefore, no adaptation or special calibration of the revolution counter to a specific type of screwdriving tool is necessary, meaning that the revolution counter with a detection device designed as a gyroscope can be universally used and / or retrofitted to any screwdriving tool for counting revolutions.

[0028] The Fig. 1 shows a device 10 according to the invention, which is arranged on a screwing tool 104, during an adjustment process of a furniture fitting 200 by means of the screwing tool 104, wherein the screwing tool 104 is designed as a bit holder which carries a rotary blade 12 and is clamped at its end opposite the rotary blade 12 into a drill chuck 102 of an electric screwing machine 100, which is designed as a cordless screwdriver. By means of the electric screwing machine 100, the screwing tool 104 clamped in the drill chuck 102 is set in rotation to rotate the rotary blade 12, wherein the screwing tool 104 extends sectionally through the device 10 between the rotary blade 12 and the drill chuck 102 and the device 10 is fastened to the screwing tool 104 in such a way that the device 10 rotates in the rotation direction R at the same rotational speed as the screwing tool 104 and the rotary blade 12.

[0029] During the illustrated adjustment process, the furniture fitting 200 is individually adjusted by rotating an adjustment member 204 of an adjustment mechanism 202 of the furniture fitting 200 by means of the rotary blade 12 and the screwing tool 104.

[0030] The Fig. 2 shows a device 10 according to the invention in a schematic perspective view from the outside. The device 10 comprises a housing 32 which accommodates all mechanical and / or electronic components of the device 10 and protects them from external influences, in particular from mechanical stress and / or environmental influences such as moisture.

The connection socket 34 can be designed, for example, as a USB socket and can be used to connect the device 10, for example, to an external power supply for charging and / or to supply electrical energy and / or to a data transmission cable for data transmission. The receiving opening 20 is designed to accommodate the screwing tool 104.The screwing tool 104 can be pushed through the receiving opening 20, in particular partially or completely, through the device 10.

[0031] The Fig. 3 shows the device 10 from the Fig. 2 in an open state, in which the housing 32 and the remaining components arranged within the housing 32 in the closed state of the device 10 are shown separately. The device 10 comprises a revolution counter 14, which in the closed state of the device 10, as shown in Fig. 2 is shown, is arranged in the interior of the housing 32. By means of the revolution counter 14, which is designed as a sensory revolution counter 14, revolutions of the device 10, in particular the revolutions of a screwing tool 104 which extends through the receiving opening 20 of the device 10, as well as the revolutions of a rotary blade 12 which may be connected to the screwing tool 104, can be detected. In particular, by means of the sensory revolution counter 14, revolutions in the direction of rotation R about the longitudinal axis of the device 10 can be detected, wherein the longitudinal axis of the device 10 is preferably identical to the longitudinal axis of a screwing tool 104 in the receiving opening 20.

[0032] The sensory revolution counter 14 comprises a detection device 16, which is designed as a sensory detection device 16, in particular as an acceleration sensor and / or a gyroscope, by means of which acceleration data and / or rotation data relating to the revolutions of the screwing tool 104, the device 10, and / or the rotary blade 12 can be detected. Using the sensory detection device 16, it is possible to detect acceleration data and / or rotation data relating to the revolutions, from which a number of revolutions can be derived, without the need for prior adaptation and / or calibration of the revolution counter 14 to a specific type and / or type of screwing tool. In this way, it is possible to use the device 10 with the sensory revolution counter 14 universally on any screwing tool and / or to retrofit it later.

[0033] Furthermore, the sensory revolution counter 14 of the device 10 comprises an electronic data processing device 22, an electronic control device 30, and an electronic communications unit 28. The data processing device 22, the communications unit 28, and the control device 30 can be arranged together in a computing unit embodied as a chip or can be configured separately from one another as independent computing units. The control device 30, the communications unit 28, the data processing device 22, and the sensory detection device 16 can each be interconnected in a signal-conducting manner.The sensor data acquired by the sensory detection device 16, in particular the acquired acceleration data and / or rotation data, are transmitted from the sensory detection device 16 to the electronic data processing device 22 for evaluation. The electronic data processing device 22 evaluates the sensor data, in particular the acceleration data and / or rotation data, wherein, in particular, a number of revolutions is derived from the data by means of the data processing device 22. The number of revolutions derived from the sensor data corresponds to the number of revolutions of the screwing tool 104 in the rotation direction R, which are performed, for example, during an adjustment process of a furniture fitting 200.

[0034] The number of revolutions of the screwing tool 104 derived by the data processing device 22 can be output, for example, by the output unit 26 in the form of a illuminated LED and / or on a display device embodied as a display. Furthermore, the sensor data and / or the derived number of revolutions can be transmitted via the connection socket 34 by means of a cable and / or by means of the electronic communication unit 28 wirelessly, for example via mobile radio and / or Bluetooth, to an external data processing device 302, an external control device 304, an external input unit 306, and / or an external output unit 308.In addition, the sensor data acquired by the sensory detection device 16 and / or the number of revolutions derived by the electronic data processing device 22 can be transmitted to the electronic control device 30 of the revolution counter 14, wherein the control device 30 can control a screwing machine 100, by means of which the screwing tool 104 is set in rotation, based on the acquired sensor data and / or the number of revolutions. The data processing device 22 can derive control specifications for the control device 30 based on the sensor data and transmit them to the control device 30, on the basis of which a screwing machine 100 can be controlled.If an operator of the device 10 has specified an intended target number of revolutions via the input unit 24, the data processing device 22 can compare a current number of revolutions of the screwing tool 104 derived from the sensor data of the sensor detection device 16 with the intended target number of revolutions and, upon reaching the target number of revolutions, derive control specifications which cause the control device 30 to stop the screwdriving machine 100. In this way, a target number of revolutions matching a desired setting of a furniture fitting 200 and corresponding to this desired setting can be specified by an operator via the input unit 24, wherein the screwdriving machine 100 is automatically stopped by the control device 30 upon reaching the number of revolutions of the screwing tool 104 matching the setting of the furniture fitting 200.In this way, the desired adjustment of the furniture fittings is achieved easily, precisely and reliably.

[0035] By means of the electronic communication unit 28, the device 10 can also communicate wirelessly with an external control device 304 in the screwdriving machine 100, so that control specifications derived from the data processing device 22 can be wirelessly transmitted to the screwdriving machine 100 for control. Furthermore, by means of the communication unit 28, derived numbers of revolutions can be transmitted to an external output unit 308 arranged on the screwdriving machine 100, for example a display on the screwdriving machine 100 or an LED on the screwdriving machine 100, so that the current number of revolutions or a current machine status, for example a signal when the target number of revolutions is reached, is signaled to the screwdriving machine 100. Furthermore, the sensory revolution counter device 14 comprises an energy storage device 18, which can be designed in particular as a rechargeable battery, in particular as a lithium battery.The energy storage device 18 can be used to supply electrical energy to the electrical components of the sensor-based revolution counter, in particular the data processing device 22, the communication unit 28, the control device 30, and the sensor-based detection device 16. The energy storage device 18 can be recharged via the connection socket 34, via which, for example, a USB cable can be connected.

[0036] The Fig. 4 shows the device 10 from Fig. 3 in an open state, wherein the device 10 is shown in an exploded view so that the schematically illustrated structure of the device 10, in particular of the sensor-based revolution counter 14, is more clearly visible. The data processing device 22, the communication unit 28, and the control device 30 are arranged together with the connection socket 34 on an electrical circuit board. It is also possible for the connection socket 34, the data processing device 22, the communication unit 28, and the control device 30 to be arranged separately and / or spaced apart from one another instead of on a common circuit board.

[0037] The Fig. 5 shows a furniture fitting 200, which can be adjusted via an adjustment mechanism 202 that is adjustable by means of a rotary blade 12. The furniture fitting 200 is designed as a furniture fitting 200 for a furniture front 212 for opening and closing a cabinet, wherein the furniture front 212 can perform a pivoting movement for opening and closing the cabinet by means of the furniture fitting 200. The furniture front 212 is attached to support arms 210, wherein the support arms 210 connect the furniture front 212 to the adjustment mechanism 202.

[0038] The furniture fitting 200 is adjustable by means of the adjustment mechanism 202. In particular, a load-bearing capacity and / or a counter-torque and / or an opening angle and / or an inclination for the furniture front 212 of the cabinet can be adjusted via the adjustment mechanism 202, so that the cabinet opens and closes as intended. In order to precisely and reliably adjust the furniture fitting 200 by means of a rotary blade 12 via the adjustment mechanism 202, knowledge of the revolutions of the rotary blade 12 when adjusting the adjustment mechanism 202 is necessary, since an intended setting of the furniture fitting, for example an intended load-bearing capacity, corresponds to a defined number of revolutions of an adjustment screw 204 of the adjustment mechanism 202.

[0039] For example, if the intention is to adjust the furniture fitting 200 via the adjustment mechanism 202 using a screwing machine 100, the number of revolutions of the rotary blade 12 during an adjustment process of the furniture fitting 200 with a device 10 according to the invention can be detected by counting the revolutions of the screwing tool 104 in order to precisely and reliably implement a desired adjustment of the furniture fitting 200 using the sensory revolution counting device 14 of the device 10. Using the sensory revolution counting device 14 of the device 10, the revolutions of the rotary blade 12 can be detected by counting the revolutions of the screwing tool 104, so that the adjustment process of the furniture fitting 200 can be stopped when an intended number of revolutions is reached.A suitable number of revolutions for a particular furniture fitting 200 when adjusting the furniture fitting 200 via the adjustment mechanism 202 can be taken, for example, from an online database or from the operating instructions for the furniture fitting 200.

[0040] The Fig. 6 and 7each show a detailed view of the adjustment mechanism 202 of the furniture fitting 200 in different adjustment states. The adjustment mechanism 202 comprises a spring 208, wherein the spring 208 is connected at a first end of the spring 208 to one of the support arms 210 and at its other end to an adjustment screw 204. By means of the adjustment screw 204 of the adjustment mechanism 202, the preload of the spring 208 can be adjusted by adjusting a tensile force on the spring 208. By adjusting the preload force of the spring 208, which is connected to the support arm 210 to which the furniture front 212 is attached, the opening torque and / or the load-bearing force and / or the counter-torque and / or the opening angle of the furniture fitting 200 can be individually adjusted.

[0041] To adjust the preload force of the spring 208 and thus to adjust the furniture fitting 200, the adjusting screw 204 of the adjusting mechanism 202 has a crown wheel 206, wherein the adjusting screw 204 can be rotated via the crown wheel 206 by means of a rotary blade 12, wherein by rotating the adjusting screw 204 by means of a rotary blade 12 the end of the spring 208 connected to the adjusting screw 204 travels a travel path V along the adjusting screw 204, wherein the preload force of the spring 208 changes by moving the spring end along the adjusting screw 204.

[0042] In the Fig. 6 a setting state of the furniture fitting 200 is shown, in which a low preload force of the spring 208 is set, so that a low counter torque of the furniture fitting 200 results. Fig. 7 The position of the adjustment mechanism 202 shown results in a high preload force of the spring and thus in a high counter-torque of the furniture fitting 200.

[0043] In order to be able to precisely and reliably adjust the adjustment mechanism 200 to a suitable setting intended for a particular furniture fitting 200, it is advantageous if the adjustment screw 204 is rotated via the crown gear 206 with a previously defined and intended number of revolutions. Since the number of revolutions of the adjustment screw 204 corresponds to the number of revolutions of a rotary blade 12 and thus of a screwing tool 104, the use of a device 10 according to the invention with the revolution counting device 14 can be used to count the number of revolutions when adjusting the furniture fitting 200, thus ensuring at all times that the furniture fitting 200 is correctly adjusted with the required number of revolutions.

[0044] The operating instructions for a furniture fitting 200 may, for example, already contain information about how many turns of the adjusting screw 204 are required to set a desired setting of the furniture fitting 200 via the adjustment mechanism 202 in order to set a counter-torque suitable for the furniture and / or a suitable opening angle of the furniture front 212. An operator who adjusts the furniture fitting 200, for example using a screwing machine 100, can use a device 10 according to the invention with a sensory revolution counter 14 to adjust the furniture fitting 200. This device counts the revolutions of the screwing tool 104 and thus the revolutions of the rotary blade 12 and the revolutions of the adjusting screw 204 when adjusting the furniture fitting 200 via the adjustment mechanism 202.By reading the number of revolutions, for example, using an output unit 26, the operator can determine when the required number of revolutions of the adjusting screw 204 has been reached. Consequently, a furniture fitting 200 can be adjusted quickly, easily, and precisely as intended using the device 10 with sensory revolution counter 14. Furthermore, using the device 10 with sensory revolution counter 14, other furniture fitting systems than the one shown with spring 208 can be adjusted, provided a number of revolutions of the screwing tool 104 corresponds to an intended adjustment of the furniture fitting system. For example, using the device 10 with sensory revolution counter 14, fitting systems can also be adjusted which comprise at least one oil damper instead of a spring 208.

[0045] The Fig. 8 shows a mobile terminal 300, which is designed in particular as a smartphone or tablet and comprises an external data processing device 302, an external control device 304, an external input unit 306, an external output unit 308, and an external communication unit 310. Preferably, a computer program product, in particular a mobile application, is executed on the mobile terminal 300, by means of which an operator can set, configure, and / or control the device 10, in particular the sensory revolution counter 14 of the device 10, as well as retrieve and / or transmit data. The mobile terminal 300 can communicate with the communication unit 28 of the device 10 by means of the external communication unit 310 of the mobile terminal 300, which can be designed, for example, as a Bluetooth module or mobile radio module of the mobile terminal 300.In particular, control specifications and / or sensor data and / or the number of revolutions derived from the sensor data can be exchanged between the communication unit 28 of the device 10 and the external communication unit 310 of the mobile terminal 300. The external input unit 306 and / or the external output unit 308 can be configured as a touch-sensitive display, in particular as a touchscreen, of the mobile terminal 300. By means of the external output unit 308, the number of revolutions currently derived from the sensor data of the detection device 16 can be displayed on the mobile terminal 300 during an adjustment process of a furniture fitting 200.By means of the external input unit 306, an operator can make inputs via the mobile terminal 300; in particular, desired settings of the furniture fitting 200, in particular intended target rotational speeds for the screwing tool 104, can be specified via the external input unit 306 via the touchscreen of the mobile terminal 300.

[0046] Inputs made by means of the external input unit 306, in particular predetermined target rotational speeds, can be transmitted via the communication unit 310 of the mobile terminal 300 to the revolution counter 14 of the device 10 and evaluated there, in particular by the data processing device 22. The number of revolutions derived by the data processing device 22 of the device 10 can be transmitted to the mobile terminal 300 via the communication unit 28 and displayed there for an operator by the external output unit 308. Numbers of revolutions derived by the data processing device 22 and / or derived control specifications can also be transmitted to the mobile terminal 300 and further processed there by the external data processing device 302 and / or the external control device 304.In addition, sensor data, in particular acceleration data and / or rotation data, acquired by means of the acquisition device 16 can be further processed to the external data processing device 302 and / or the external control device 304 for deriving a number of revolutions and / or for deriving control specifications and / or for controlling, in particular, the screwing machine 100, in the mobile terminal.

[0047] In addition, the mobile terminal 300 can be configured to transmit control specifications to the screwdriving machine 100 via the communication unit 310 in order to control the screwdriving machine 100 based on the number of revolutions of the screwdriving tool 104. The mobile terminal 300 can also have a data memory on which sensor data acquired by the detection device 16, the number of revolutions and / or control specifications derived from the data processing device 22 or the data processing device 302, as well as target revolution numbers specified by means of the input unit 306 and / or by means of the input unit 24 can be stored.In addition, prefabricated profiles, for example, profiles with different target rotation speeds for different furniture fittings 200, can be stored in the data memory of the mobile device 300, so that an operator can select a profile suitable for their furniture fitting 200. A suitable profile and / or a suitable target rotation speed for the furniture fitting 200 is selected, and control specifications are derived based thereon, for example. Furthermore, the mobile device 300 can be used to access, for example, a database, in particular an online database, in which prefabricated profiles and / or suitable target rotation speeds for different furniture fittings 200 are stored and retrievable.In addition, the operating instructions for a furniture fitting 200 can contain scannable barcodes and / or QR codes, which can be scanned with a camera of the mobile device 300 and from which suitable target rotation speeds for the respective furniture fitting 200 can be derived.
