Abstract

Bird trapper, structured in one or more tubular launchers (4) that have captive shuttles (5) of the capturing network (3); characterized in that each tubular launcher (4) internally disposes a first spring (8a) of very high elastic constant and externally a second spring (8b) of lower elastic constant that act together when firing the shuttles (5).

Description

Bird catcher

The present invention concerns a grabber of birds used, for example, to capture (without injuring) pigeons in an open place (park, square or garden); although his  application to capture (without injuring) other types of birds or small animals, without altering the essence of the invention.

In the current state of the art already known devices of this type to catch birds. For example, and enter others:

-

the US4912869 patent, which adapts to a conventional hunting shotgun several tubular with shuttles that, when firing the weapon expand a network;

-

the Utility Models ES 1033830 and ES 1046406, both of its own applicant, who achieve the goal of expanding the network with purely mechanical solutions (without using shotguns or other weapons hunting).

A problem not solved in the devices known capturers is the speed of launch (problem that it becomes apparent even when, as in the aforementioned Models of the same applicant, the problem of the Simultaneity of firing in all tubular launchers).

The fundamental object of the invention is to achieve a greater immediacy of the launch in this type of capturers of birds. For this, the bird catcher according to the invention, being of the structured in one or several tubular launchers that they have captive shuttles of the capture network, it is characterized because each tubular pitcher:

to)

internally has a first spring of very high elastic constant and externally a second spring of lower elastic constant;

b)

means to retain compressed to the first spring inside the tubular pitcher and means for position expanded to the second spring outside the tubular pitcher with the shuttle in firing position;

C)

both of them Springs act together when firing the shuttles.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 represents an overview schematic in profile of a bird catcher according to the invention, with detail of the shuttle (5) on the lower floor.

Figure 2 represents a section of one of the tubular launchers (4), with its components and corresponding shuttle (5) in firing position -figure 2a- and in position triggered -figure 2b-.

An example of practical, non-limiting embodiment of the present invention.

The present invention relates to an apparatus for capture birds and other small animals without causing them harm. Be structure in one or several tubular launchers (4) that have shuttles (5) captives (31) of the capture network (3); so that, when the shuttles are fired (5) the net (3) expands on the birds or other animals, to capture them without causing harm.

Each tubular pitcher (4) forms a window torn (4a) in its mouth, to allow the passage of the rope or cable (31) that holds the shuttle (5) captive to the net (3).

In accordance with the invention, each tubular launcher (4) internally has a first spring (8a) and externally a second spring (8b).

The inner spring (8a) is very high elastic constant and in relation to said spring (8a) the captor object of the invention involves means to retain it compressed inside the tubular pitcher (4) while the corresponding shuttle (5) is housed in said tubular (4) in firing position.

The outer spring (8b) is less constant elastic than the spring (8a) and in relation to said spring exterior (8b) the grabber object of the invention involves means for retain it expanded outside the tubular caster (4) in both the corresponding shuttle (5) is housed in said tubular (4) in firing position.

When firing, both springs (8a), (8b) act jointly and simultaneously on the shuttle (5), producing its quasi-instantaneous shot / launch.

According to the embodiment shown, those cited means for retaining compressed spring (8a) inside the tubular pitcher (4) with the shuttle (5) in the position of shot are:

-

a head (50) that functions as a latch latch at the base of the shuttle (5);

-

a hole-window (40) in the tubular caster (4), Y

-

a trigger (83) mounted externally on the tubular 5 launcher (4) which, through the hole-window (40) retains the shuttle (5) by its head-latch (50) compressing the spring (8a) -see figure 2a- that is released and expanded when shooting-see figure 2b-.

According to the embodiment shown, those cited means for retaining expanded spring (8b) outside the tubular pitcher (4) with the shuttle (5) in the position of shot are:

-

a base-stop (41) to which the spring (8b) is fixed by one of its ends, and

-

a inextensible cable (81) that fixes its two ends to the end opposite of the spring (8b).

Said inextensible cable (81) is guided in the tubular pitcher (4) by means of rings (42) and guided in the trigger head (50) of the shuttle (5) by some pockets (51); so that, in the firing position of the shuttle (5), most of the cable (81) is inside of the tubular pitcher (4) and the spring (8b) expanded occupying outwardly most of the tubular pitcher (4) -see figure 2a- which is compressed when firing, when the cable (81) becomes occupied this area -see figure 2b-.

Claims (3)

1. Bird catcher, of those structured in one or several tubular launchers (4) that have captive shuttles (5) of the capture net (3); characterized in that each tubular pitcher (4):

to)

internally has a first spring (8a) of very high elastic constant and externally a second spring (8b) of lower elastic constant;

b)

means to retain compressed to the first spring (8a) inside the tubular pitcher (4) and means for positioning expanded to the second spring (8b) in the outside of the tubular pitcher (4) the shuttle (5) being in firing position;

C)

both of them Springs (8a), (8b) act together when firing the shuttles (5).

2. Bird catcher, according to the preceding claim, characterized in that said means for retaining a compressed spring (8a) inside the tubular pitcher (4) with the shuttle (5) in the firing position are:

to)

a head (50), which functions as a latch latch on the base of the shuttle (5);

b)

a window hole (40) in the tubular caster (4) Y

C)

a trigger (83) which, through the hole-window (40) retains the head-latch (50) and releases it at shoot.

3. Bird catcher, according to claim 1, characterized in that said means for retaining expanded spring (8b) outside the tubular launcher (4) with the shuttle (5) in firing position are:

to)

a base-stop (41), to which the spring (8b) is fixed by one of its ends;

b)

a inextensible cable (81) fixed to the spring (8b) at its other end and guided in the tubular pitcher (4) which, for this purpose, involves two rings (42) and on the head (50) of the shuttle (5) that, to such an effect, it involves cashier-guide paths (51).
