Device for measuring surface dimensions of an object
View Patent ↗The invention relates to a device for measuring surface dimensions of an object, comprising an elongate flexible material piece, which is supported on a roller in such a way that the material piece can be unwound and on the end of which a probe is provided, wherein the roller is connected to a base of the device in such a way that the roller can be rotated about a vertical axis, and wherein two sensors are provided, by means of which the unwound length of the material piece and the angle of the roller with respect to the base can be detected, wherein the base consists of a planar bottom plate and the roller is arranged on the side facing away from the contact surface of the bottom plate.
1. A device for measuring surface dimensions of an object, having an elongated flexible material piece that can be unrolled, supported on a roller, on the end of which a probe is provided, wherein the roller is connected to a base of the device such that it can rotate about a vertical axis, and wherein two sensors are provided, by means of which the unrolled section of the material piece and the angle of the roller in relation to the base can be detected, characterized in that the base consists of a flat base plate, and the roller is disposed on the surface of the base plate facing away from the supporting surface, wherein the roller is connected to a base of the device such that it can rotate about a vertical axis, and wherein the roller is supported on a swivel arm, by means of which the axis of the roller can be repeatedly moved toward the base.
2. The device according to claim 1 , characterized in that a pre-tensioning means, preferably a spring, is provided, with which a force is exerted on the elongated flexible material piece for winding it onto the roller.
3. The device according to claim 1 , wherein the elongated flexible material piece is a tape measure.
4. The device according to claim 1 , wherein the base plate exhibits a stop angle for aligning the device with an edge of an object.
5. The device according claim 1 , wherein the probe is designed as a handpiece.
6. The device according to claim 1 , wherein the probe exhibits a pointed tip.
7. The device according to claim 6 , wherein the tip of the probe is designed as a ball bearing mounted scanning roller, the roller axis of which runs parallel to the vertical axis of the device.
8. The device according to claim 1 , wherein the vertical axis runs through a releasable, preferably magnetic, bearing block connected to the base plate.
9. The device according to claim 1 , wherein at least one of the sensors is a magnetic sensor.
10. The device according to claim 1 , wherein the device can be controlled with a remote control.
11. The device according to claim 1 , wherein the device exhibits a transmitting means, preferably an electronic transmitting means, in particular a Bluetooth transmitter, with which the measurement values can be transmitted to a processing unit.
