English -English (FI) (5 * 0 Device for lifting net or hook wire under ice -

Anordning för lyftning av nät- eller kroklinan under isen

The invention relates to a device for lifting a net or hook wire from under a gutter, which device comprises an upper arm provided with a handle and a lower arm connected to it by means of a central joint to the hook head.

Lifting devices of this type are used in winter fishing to reach and lift fishing nets, hooks, seines and other fishing gear from under the ice. One device of this type is known from Finnish patent publication 51260.

However, there is one serious drawback to the net or hook wire hoist shown above. When pushing the device under the ice, its lower end tends to press naturally towards the bottom due to gravity, so that pushing the lower arm sideways under the ice is not very easy. Thus, such a device is not able to hook the net or hook wire from very long outside the opening.

61263

The object of the invention is to eliminate the above drawback. The invention is characterized in that the lower arm is lighter than water so that it rises upwards when it enters the water. The net or hook wire can then be hooked from the opening even further under the ice when using the device according to the invention. The lower arm rises by itself against the ice thanks to the lighter structure of the lower arm and the central joint included in the lifting device. At the same time, the device is light and easy to handle.

In a preferred embodiment of the invention, a measuring scale is formed on the arm of the device to measure the strength of the ice.

The invention will now be described in detail by means of an exemplary embodiment with reference to the accompanying drawing, in which Figure 1 shows a device according to the invention in use and Figure 2 shows a device according to another embodiment of the invention.

In the embodiment shown in Figure 1, the device according to the invention is used for reaching and lifting the hook wire 7 under ice. The device comprises an upper arm 2 provided with a handle 1 and connected via a central joint 3 to the lower arm 4. The central joint 3 allows the lower arm 4 to rotate freely relative to the upper arm 2. The lower arm 4 further comprises a hook 5 by means of which the line 7 can be easily reached and pulled onto the ice from the opening 8.

According to the invention, the lower arm 4 is made of hollow plastic and lighter than water. Due to its light weight, the lower arm 4 with its hook head 5 rises automatically against the ice when the lifting device is pushed into the water from the opening 8. In this case, the knot wire 7 is easy to reach even further, always from the distance of the lower arm 4 from the opening 8.

A measuring scale 6 is further formed on the arm 2, 4 of the hook device. The purpose of the measuring scale 6 is to facilitate the measurement of ice thickness, which can be done with the device according to the invention by pushing the arm 4 under ice and reading the ice thickness from the scale.

In the embodiment shown in Figure 2, the hook head 5 is connected to the upper arm 2 substantially fixedly, whereby the device can be used advantageously as a fish hook or the like.
