DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
The invention relates to a brake for a fishing reel, in particular for fly fishing, wherein the crank can only be turned in one direction, and the brake preferably only works in the unwinding direction.
2. Prior Art
The device has the purpose of increasing the preset braking force when the line is reeled in. Up to now, with reels of the "anti-reverse" type, the brake acts with equal strength when pulling off the line and when reeling it in against the resistance of the fish. This has negative effects when drilling, i.e. fighting the fish, since a required change of the braking force can only take place by adjusting the brake adjustment nut.
To do this it is necessary to let go of the crank, which can mean the loss of the fish (DE 43 02 840 C1).
Fishing reels are known (U.S. Pat. No. 4,715,555), which attempt to remedy this disadvantage by bridging the brake, in that the crank is directly coupled with the reel by means of an interlocking detent device.
The possible blocking of the line, because the brake is no longer effective, is disadvantageous in connection with this embodiment. Because of this there is the danger that the line will break. Another disadvantage lies in the transition from the braking effect to blocking since, if there is a pull on the line, the device does not yet correctly block during this moment of switching, and the brake no longer works effectively. The hard shocks being created in the process can also lead to breaking of the line.
OBJECT AND SUMMARY OF THE INVENTION
It is therefore the object of the invention to improve a reel of the above mentioned type in such a way that the disadvantages of the known embodiment are prevented by the most simple means.
This object is attained in accordance with the invention in that a pressure element is associated with the axially movable, but fixed against relative rotation, disk of a disk brake, which is provided with tongues on one side which are located, axially displaceable, in the groove of the hollow shaft, and which is provided on the other side with several inclined planes on the front, on whose respectively lowest point revolving bodies, for example balls, are located, which in turn are supported on the inclined planes of a crank located rotatably on the hollow shaft, to which balls have been assigned on the opposite side, which are supported by a ring fastened on the hollow shaft.
By means of this attainment of the object a disk brake is made possible, which has an adjusted braking force when the line is pulled off by the fish and which, when actuating the crank against the pull of the line, provides an increased braking force on the brake disk by means of the the revolving bodies rolling off on the inclined planes and the additional pressure generated by this.
The increase of the braking force which can be metered without the danger of blocking is particularly advantageous.
In an advantageous embodiment of the described attainment of the object, an elastic ring is disposed between the pressure element and the hollow shaft, which cancels the additional axial force when the crank force is reduced. Then the brake only acts with the previously set force.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the invention represented in the attached drawings will be explained in what follows.
Shown are in:
FIG. 1, a cross section through the brake,
FIG. 2, the roll-off of the inclined planes of the pressure element 8 and the crank 9 with the revolving bodies, and
FIG. 3, the section along the line A--A in FIG. 1.
The basic structure of fly reels is known per se. For this reason it will not be discussed here.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) OF THE INVENTION
The brake of a fly reel, shown in detail in the drawings, acts on a reel 1, on which the line, not represented here, is received. The reel has friction surfaces 2 and an axially movable disk 3, whose protrusions engage the grooves 4 of the hollow shaft 5 and are fixed against relative rotat
