DE19637585A1 - Speed measurement device for roller skates e.g. in-line skates - Google Patents

Abstract

The device comprises a sensor (2) for determining the number of roller rotations of a roller (4) and a display unit (1) for indicating the measured parameter. Both roller shoes each have at least one sensor mounted on them. A microprocessor evaluation unit determines the highest revolution rate from the detected rollers and feeds it to the indicator unit.

Description

The invention relates to a device according to the preamble of claim 1. With This device can cover the distance covered by roller skates and derived therefrom Sizes, especially the speed of a roller skate Person, identified and displayed.

Measuring process via the inductive query of the number of wheel revolutions using Permanent magnet and sensor in connection with a reading unit (microcomputer) that the Wheel revolutions with the help of the freely entered wheel circumference and an integrated Real-time clock evaluates. By recording the travel time (movement time) and the covered distance can u. a. query one or more of the following parameters and display:

• 1. Current driving speed,
• 2. average speed,
• 3. Actual travel time,
• 4. Kilometers traveled,
• 5. total kilometers traveled,
• 6. maximum speed reached,
• 7. time,

The data transmission (pulse transmission) between sensor and reading unit is both about Cable as well as wireless possible.

The reading unit is equipped with a liquid crystal display.

Power is supplied by the battery. All components are water-repellent (or waterproof).

As an option, the human heart rate and the Reading unit are transmitted. This gives u. a. one or more of the following Parameter:

• 1. Current heart rate
• 2. Setting a heart rate zone (upper and lower limit)
• 3. Optical and / or acoustic signal when the set value is exceeded or undershot Limits
• 4. Ability to query the individual times above, below and within the set time Limits.

It is known to use such measuring devices in the bicycle sector. With this use motion is queried on only one wheel.

With inline skaters, the movement-specific sequence (reciprocal Ground contact of the skater, braking, etc.) the speed with sufficient Accuracy cannot be determined by querying a single role.

The mounting and construction of the components (reading unit, sensor etc.) are for the Designed for mounting on bicycles.

The object of the invention is to provide a person moving with inline skaters display current driving speed and other of the parameters described above.  

It is possible to read the parameters during the movement sequence by using the Reading unit is worn similar to a wristwatch or integrated in the wrist protector.

Query of the rotations of at least one role of the left and the right In line skate shoes. Output of the higher number of revolutions by the evaluation module. The Evaluation module, which is responsible for the selection and transmission of the higher number of revolutions, can be integrated both in the sensor unit of a shoe and in the reading unit.

If the evaluation module is integrated in the reading unit, each sensor has one Schuhs wirelessly transmits the rotation frequencies directly to the reading unit.

If the evaluation module is integrated in one of the shoe sensors, one can Revolution frequency can be taken directly from this. The rotational frequency of the The role on the second shoe is transmitted wirelessly to the evaluation module in shoe one. From The evaluation module is then, via a second wireless connection, the higher of the two Frequencies transmitted to the reading unit (sketch appendix to A).

The wireless transmission links consist of transmitter and receiver and may be in do not affect their functionality.

Utilization of the details described in claim 1 for users of inline skaters.

Modification of the speedometer according to the state of the art to the conditions or movement sequence specific for in-line skaters
Determination of the speed of movement (and other parameters) by measuring at least two revolutions, ie attaching and querying at least one sensor to each shoe.

Reading the parameters during the movement for the user of inline skaters possible.  

The speed measurement system for inline skaters has the following features that correspond to the status of the Technology include:

• 1. Inductive query of the wheel revolutions by means of permanent magnet and sensor,
• 2. As an option additional sensor for heart rate detection,
• 3. Wireless data transmission path between sensor and reading unit,
• 4. Reading unit (microcomputer) that evaluates the wheel revolutions with the help of the wheel circumference that can be freely entered and an integrated real-time clock. The following parameters can be determined and displayed in whole or in part:
  Current driving speed
  Average speed,
  Actual travel time,
  mileage covered,
  Total kilometers traveled,
  Maximum speed reached,
  Time.
• 5. As an option evaluation of the heart rate
• 6. Energy supply with battery
• 7. Waterproof / waterproof design.

An inline skater has a rail that is firmly attached to a special shoe several rolls (usually four) attached in a line. Inline skaters make it possible the user to move on suitable surfaces (rolling). Of the The shape of the movement is similar to that of a skater.

The following is a more detailed description of exemplary embodiments of the invention. For Illustrations are sketches attached with the representations:

Fig. 1 view-line skate shoe,

Fig. 2 vertical section AA,

Fig. 3 view meter reading unit,

Fig. 4 first variant,

Fig. 5 second embodiment.

A permanent magnet (item 3 ) is attached to each roll (item 4 ) of the left and right shoe. There is a sensor (item 2 ) attached to the rail (item 5 ) of each shoe so that the rotating magnet (item 3 ) is at a distance of approx. 1- each time the roller (item 4 ) rotates. 2 mm past the sensor.

The reading unit (item 1 ) is worn by the user in the form of a wristwatch. Another variant would be integration in or on a wrist protector.

The data transmission between the sensors and the reading unit and between the Sensors with each other (depending on the variant) are wireless.  

Alternative designs execution

a) Complete set with universal fastening elements for Subsequent installation on inline skaters from various manufacturers.

• b) Extension components in the form of adapters for use on bicycle speedometers on the market (Fahr rad computer).
• c) OEM kit for integration into the product by the Manufacturer.
