Definitions
- the invention relates to a device for holding the log transmitter of boat speedometers with a sleeve body fixedly arranged in a perforation of the boat hull with a central longitudinal opening in which the like with an impeller.
- Loggers equipped as a pulse link are separable, insertable and durable.
- a log transmitter which is accommodated in a boat-fixed sleeve body and has a rotatable impeller which can be influenced by the water, is used to generate measuring pulses which are fed to a display via electrical conductors.
- suspended and floating substances in the water often interfere with or inhibit the movement of the impeller, in particular after the boat has been idle for a long time, which makes cleaning or repair work necessary. To do this, it is necessary to remove the logger from the sleeve body. During the removal and the subsequent insertion work of the logger, larger amounts of water each pass into the boat interior via the central opening of the sleeve body, which can often only be removed in a cumbersome manner.
- the sleeve body at the end facing away from the water tightly carries a head part which has a coaxial central opening of the same cross-sectional size that is closely connected to the central longitudinal opening of the sleeve body, the longitudinal and central openings together tightly seal the logger record and that the longitudinal and central openings can be blocked or released depending on the positions of the logger by a locking slide that can be moved tightly in the head part.
- the locking slide can be pushed into the closed position for the central openings or when the logger is subsequently inserted and the logger is approximately reached
- the isolating slide prevents the inflow of water through the longitudinal and central openings into the interior of the boat over the duration of the short-term withdrawals or insertion movements.
- the head part is provided directly or by means of a head part fixed
- the head part - in a recess coaxial with the central opening - has a sliding ring accommodated with axial play against spring force, which together with a flat annular body fixedly arranged on the head part and carrying a further sealing ring limit the locking slide plane on the top and bottom
- the slide ring is preferably arranged on a sealing ring which provides the spring force and is arranged in the recess, for example an O-ring made of resiliently elastic Material tightly supported and displaceable and durable by material stresses of the sealing ring in the direction of the ring body in order to be moved out of this position by a component of the plug-in force of the locking slide acting on the sliding ring transversely to the direction of movement of the locking slide to release the locking slide plane.
- the ring body is expedient from a rigid, for. B. formed metallic material and provided with a groove in the area of the gate valve plane for receiving the further sealing ring.
- sealing ring acting on the slide ring from any other suitable material, preferably a resilient plastic, e.g. to form a foamed plastic.
- Sealing rings of this type are expedient at low immersion depths of the hull, while greater immersion depths of the hull can be achieved by means of spring forces and seals, e.g. Make coil springs necessary.
- the device in a further embodiment of the device it is provided to connect the log transmitter to the head part by means of a cover having an axial control curve, for example a screw thread, and to fix it in the longitudinal and central openings of the sleeve body and the head part by means of the cover. By rotating the cover, the log transmitter can be removed from or inserted into the device with little effort.
- An alternative embodiment of the device for solving the problem is proposed according to another invention by the measures of claim 10.
- the locking slide which can be moved into or out of the locking position is replaced by a pivoting locking element.
- Embodiments of the modified device can be found in claims 11 to 17.

- FIG. 1 shows a section 1 of a boat hull wall, on which the device 2 is fixed by a screw connection 3.
- the device has a sleeve body 4 with an external thread 5, which extends through an opening 6 of the hull wall 1 in the direction of the boat interior, is supported with a flange 7 on the underside 1 ′ of the hull wall 1 and by a Threaded nut 8 is fixed.
- a head part 9 is connected to the sleeve body 4 via a threaded ring 9 '.
- the head part 9 has a cylindrical central opening 10 which extends coaxially to a central longitudinal opening 11 of the sleeve body 4.
- the Mittelöf opening 10 and the longitudinal opening 11 together serve to accommodate a logger 12, which is inserted tightly into the openings 10, 11 using O-rings 12 '.
- the log transmitter 12 has a rotatable impeller 13 as a pulse generator for speed measurements.
- the log generator 12 is connected to a display device (not shown) via a cable 2 '.
- the head part 9 is further provided with a recess 14 coaxial to the central opening 10 (FIG. 2), into which a sliding ring 15 (FIG. 8) is guided with axial play, which, under the action of a spring force, for example a sealing ring formed from foamed plastic 16 stands.
- the slide ring 15 lies on the bottom 14 'of the recess 14 supported sealing ring 16 and is displaceable by this in the direction of the lower end of the head part 9.
- the head part 9 is further provided with an annular body 17 (FIGS. 1 and 5) which has a central opening 18 which is coaxial with the openings 10, 11 and an annular groove 19 for accommodating an O-ring 20.
- the sliding ring 15 and the ring body 17 form a parting plane into which a locking slide 21 (Fig. 9) formed by a flat prismatic sheet metal part can be inserted.
- the parting plane is delimited on both long sides of the locking slide 21 (FIG. 3) by guide surfaces (22).
- the log transmitter 12 has a collar 23 which can be supported in the head part 9, preferably in a cover 29 provided with a thread 29 ', with the interposition of a sealing ring 29''.
- An additional ring-shaped seal 24 in the cover 29 prevents liquid spills within the head part 9.
- the cover 29 has to be unscrewed from the head part and pulled out together with the log transmitter 12 from the sleeve body 4 and head part 9.
- the central openings 10, 11 can be blocked by inserting the blocking slide 21 from the fully drawn position into the position shown in dashed lines (FIG. 1).
- the sealing ring 16 Due to the resilience of the sealing ring 16, the sliding ring 15 presses on the locking slide 21 and at the same time the O-ring 20 of the ring body 17 bears against the underside of the locking slide 21, which means that the openings 10, 11 are sealed off by means of the locking slide 21 is effected.
- the locking slide 21 After the log transmitter 12 has been cleaned, it is to be pushed into the openings 10, 11 in the opposite direction of movement, the locking slide 21 being moved outwards by the log transmitter shortly before the separation level is reached. In both directions of movement of the log transmitter 12, the locking slide 21 prevents water from escaping from the device.
