System for attachment of portable motor module to surfboards
View Patent ↗A universal attachment system wherein harnesses are provided which can be installed on a broad variety of surfboards, other boards and light watercrafts not requiring any permanent fixtures or permanent special features on said boards and are suitable for the attachment under-board of a motor module. The attachment straps are equipped with tightening devices for example ratchets and tension measuring means such as for example piezo-luminescent coating. Either the whole harness or the motor module alone are provided with the quick release means either mechanical or magnetic. The detached motor module is equipped with a capability of homing in to the radio control transmitter or traveling to a designated GPS location.
1. An attachment system suitable for use on swimming boards comprising: an adjustable board attachment harness, said harness including a tension measuring device; and a motor module affixable to the harness, where said tension measuring device is implemented as pressure sensitive paint operative to change color responsively to tension change within a strap part of the harness.
2. The system of claim 1 , wherein said tension measuring device includes an elastic expandable element attached on two sides to the harness.
3. An attachment system suitable for use on swimming boards comprising:
an adjustable board attachment harness suitable for use on a variety of swimming boards; and
a motor module affixable thereto, said motor module including a satellite based positioning control system for traveling by means of directing movement to a designated geoposition.
4. An attachment system suitable for use on swimming boards, the system comprising:
a strap harness releasably connectable to the swimming board;
a motor module connected to the strap harness;
a release mechanism operative to release, from the swimming board, the strap harness together with the motor module connected to the strap harness,
said release mechanism including at least one electromagnet.
5. An attachment system suitable for use on swimming boards, the system comprising:
A strap harness releasably connectable to the swimming board;
a motor module connected to the strap harness;
a release mechanism operative to release, from the swimming board, the strap harness together with the motor module connected to the strap harness,
said release mechanism comprising at least one magnetic lock having
an interface of permanent magnets, wherein at least one of said magnets is rotatable relative to another.
6. An attachment system suitable for use on swimming boards, the system comprising:
a strap harness releasably connectable to the swimming board;
a motor module connected to the strap harness; and
a release mechanism operative to release, from the swimming board, the strap harness together with the motor module connected to the strap harness,
the harness comprising a front board tip enclosure and a rear board tip enclosure connected by at least one longitudinal strap.
7. An attachment system suitable for use on swimming boards, the system comprising:
a strap harness connected to the swimming board;
a motor module releasably connectable to the strap harness; and
a release mechanism operative to release the motor module from the strap harness while the harness remains connected to the board,
wherein the motor module includes a homing unit operative to drive the swimming board to a radio signal.
