Abstract

A handheld device, in particular a cartridge press and/or tubular bag press, for dispensing filling material into a joint, including: a handle assembly for manually gripping the handheld device and for moving the handheld device along a joint path, a dispensing device for dispensing the filling material into the joint, and a sensor device which is designed to detect an influencing quantity. The influencing quantity influences the body geometry of a filling material body formed by the filling material dispensed into the joint, in which the handheld device is adapted to adjust a dispensing rate (r) at which the dispensing device dispenses the filling material based on the detected influence quantity.

First claim

The invention claimed is:

1. A handheld device for dispensing filling material into a joint, comprising:
a handle assembly for manually gripping the handheld device and moving the handheld device along a joint path,
a dispensing device for dispensing the filling material into the joint, and
a sensor device adapted to detect an influence quantity influencing a body geometry of a filling material body formed by the filling material dispensed into the joint,
wherein the handheld device is configured to adjust, based on the detected influence quantity, a dispensing rate at which the dispensing device dispenses the filling material,
the handheld device further comprising an operating device for inputting specification information and/or a communication device for receiving the specification information, wherein the handheld device is configured to take the specification information into account when adjusting the dispensing rate.

2. The handheld device of claim 1 , wherein the influence quantity comprises a handheld device speed at which the handheld device is moved.

3. The handheld device according to claim 2 , wherein the handheld device comprises a dispensing element for dispensing the filling material into the joint, and the handheld device speed is the speed of the dispensing element relative to the joint path.

4. The handheld device according to claim 1 , wherein the influencing quantity concerns a joint geometry.

5. The handheld device according to claim 1 , wherein the handheld device is configured to adapt the dispensing rate on the basis of the detected influence quantity in such a way that the filling material body formed by the filling material dispensed into the joint has a predetermined body geometry.

6. The handheld device according to claim 1 , wherein the handheld device is configured to adapt the dispensing rate on the basis of the influencing quantity in such a way that the dispensing device outputs a predetermined quantity of filling material per unit length of the joint path along the joint path.

7. The handheld device according to claim 1 , wherein the handheld device is adapted to increase the dispensing rate of the filling material in response to an increasing detected handheld device speed and/or to reduce the dispensing rate of the filling material in response to a decreasing detected handheld device speed.

8. The handheld device according to claim 1 , wherein the sensor device for detecting the influence quantity comprises an acceleration sensor, an odometry unit, a laser unit, an image sensor, a LIDAR unit, a RADAR unit, and/or a touch sensor.

9. The handheld device according to claim 1 , comprising a drive device and a detachable attachment device attached to the drive device, wherein the attachment device comprises the dispensing device and the drive device is for driving the dispensing device.

10. The handheld device according to claim 1 , wherein the handheld device is a cartridge press and/or a tubular bag press.

11. The handheld device according to claim 3 , wherein the dispensing element is an applicator tip.

12. The handheld device according to claim 5 , wherein the handheld device is configured to adapt the dispensing rate on the basis of the detected influence quantity in such a way that the filling material body formed by the filling material dispensed into the joint has a predetermined width.

13. The handheld device according to claim 5 , wherein the handheld device is configured to adapt the dispensing rate on the basis of the detected influence quantity in such a way that the filling material body formed by the filling material dispensed into the joint has a constant width.

14. A handheld device for dispensing filling material into a joint, comprising:
a handle assembly for manually gripping the handheld device and moving the handheld device along a joint path,
a dispensing device for dispensing the filling material into the joint, and
a sensor device adapted to detect an influence quantity influencing a body geometry of a filling material body formed by the filling material dispensed into the joint,
wherein the handheld device is configured to adjust, based on the detected influence quantity, a dispensing rate at which the dispensing device dispenses the filling material,
the handheld device further comprising a display unit for displaying status information and/or specification information concerning the dispensing of the filling material.

15. A handheld device for dispensing filling material into a joint, comprising:
a handle assembly for manually gripping the handheld device and moving the handheld device along a joint path,
a dispensing device for dispensing the filling material into the joint, and
a sensor device adapted to detect an influence quantity influencing a body geometry of a filling material body formed by the filling material dispensed into the joint,
wherein the handheld device is configured to adjust, based on the detected influence quantity, a dispensing rate at which the dispensing device dispenses the filling material, and
wherein the handheld device is adapted to record a consumption of filling material as filling material consumption information.

16. The handheld device according to claim 15 , wherein the handheld device is adapted to store the filling material consumption information in association with an identifier of a filling material container.

17. The handheld device according to claim 15 , wherein the handheld device is adapted to store the filling material consumption information in association with location information concerning the location where the consumption occurs.

18. The handheld device according to claim 1 , wherein the handheld device is adapted to provide cutting opening information, the cutting opening information representing a recommendation to the user for a cutting of an applicator tip of the handheld device to be performed by the user.
