Abstract

A landing net which incorporates mechanical or electrical measuring equipment and a weight indicator in the shaft or handle. Net support arms are pivotally mounted to the net handle and means are provided so that downward movement of the arms is transmitted to an indicator in the handle to determine the weight of fish in the net.

Description

COMBINATION LANDING NET 1. This invention relates to a combination landing net.

2. Most fishermen, having hooked and played a fish, remove it from the water by means of a landing net which may or may not be collapsible. Having thus landed the fish it is removed from the net for weighing and return to the water or keeping. Weighing is usually by means of a portable spring-balance.

3. According to the present invention there is provided a landing net with integral weight measuring equipment and a weight indicator visibly displayed in the shaft of the handle.

4. A specific embodiment of the invention will now be described with reference to the accompanying drawings in which: Drawing No 1 - illustrates the combination landing net.

Drawing No 2 - illustrates by cross section the location of a simple horizontal spring-balance by which the purpose of the invention may be achieved.

Drawing No 3 - illustrates by cross section the location of simple electrical circuitry and display by which purpose the invention may also be achieved.

Referring to Drawing No 1 the net comprises a hollow shaft to one end of which is attached a pair of arms supporting a mesh net in the currently common format. The arms are, in the case of this invention, supported by a pin-bearing or pivot fixed through the collar at point A allowing limited downward movement as illustrated by the arrow shown X. The degree of this downward movement varies according to the weight of the fish and this is measured and displayed visibly in the shaft of the handle at point B by means of mechanical or electrical equipment contained in the shaft between points A and B.

This section is clad in a transparent plastic waterproof sheath.

Referring to Drawing No 2 there is illustrated by cross-section the location of a simple spring-balance within the shaft of the handle whereby the downward movement of the arms of the net is transmitted by exaggerating gear at point I through return-spring resistance at point 2 to a simple pointer with calibrated perspex cover at point 3. The exact mechanics of this spring-balance do not form part of this invention.

Referring to Drawing No 3 there is illustrated by cross-section the location of a simple electrical circuit within the shaft of the handle whereby the downward movement of the arms of the net is measured by a strain-gauge at point A this measurement being translated by circuitry illustrated at point B for display by Liquid Crystal Display beneath perspex cover at point C. Spring-resistance is provided between points A and B. Power can be provided by photo-electric cells at point C or by batteries located elsewhere in the shaft. The details of this simple electrical circuitry do not form part of this invention.

Claims

1. A landing net with integral weight measuring equipment and weight indicator in the shaft of the handle whereby the weight of the contents of the net can be assessed prior to removal.

2. A landing net as claimed in claim 1 wherein measurement and indication of weight is achieved by means of a simple mechanical horizontal spring-balance and indicator.

3. A landing net as claimed in claim 1 wherein measurement and indication of weight is achieved by means of a simple electrical strain-gauge with attendant circuitry and a Liquid Crystal Display.
