Abstract

A boring device for coconut comprises a tube member (1) having a sharpened edge (111) at a first end (11) and a cylindrical handle (2) fixed on the second end (12), a flange element (4) fixed on a proper position spaced from the sharpened edge (111), a striking member (3) slidably movable between the handle (2) and the flange (4) thereby an impact action can be exerted to the flange (4) manually to have the sharpened edge (111) cut through the shell of coconut; a rod member (8) inserted in the tube member (1), which having a head (5) fixed on the end adjacent to the handle (2) and being biased to space from the handle (2) by a helical spring (9) mounted around the rod member (8) beneath the head (5), thereby the waste portion retained in the tube member (1) after boring can be pushed out by pressing the head (5). <IMAGE>

Description

SPECIFICATION A boring device for coconut This invention relates to a boring device, more particularly to a boring device for coconut.

The shell of coconut is thicker than most of the other fruits. In addition to it, a thick layer of fibrous exocarp makes the withdrawing of coconut milk rather difficult. Therefore, a device for easily taking out the coconut milk is attempted.

It is an object of the present invention to provide a boring device for coconut by which an easier and more efficient boring practice will be effected.

In accordance with the present invention, a boring device for coconut comprises of a tube member having a boring element at a first end thereof including a handle fixed to a second end and a flange element fixedly mounted around near the first end; a striking member capable of being operated by an external force to provide an impact action on the flange, slidably sleeved on the tube member whereby the boring element can be driven into the shell of coconut by the impact pressure applied to the flange element; as well as a longitudinal member having a head fixed at an end thereof slidably inserted in the tube member for extruding the waste portion of coconut cut off by the boring element inserted into the first end of tube.

It is preferred that the longitudinal member is provided an helical spring for biassing the head spaced from the handle.

Advantageously, the handle element of the boring device has an enlarged portion at the end opposed to the striking member to provide a restraining function with respect to the striking member, and the striking member has two enlarged cross section ends.

The presently preferred exemplary embodiment will be described in detail with respect to the following drawings, wherein: Fig. 1 is a perspective view of a boring device for coconut according to the present invention; Fig. 2 is a longitudinal section view schematically showing the relative position of a boring device for coconut and the coconut to be bored.

Fig. 3 is a withdrawing device for coconut according to the present invention.

Referring now to Fig. 1 and 2, the present invention is disclosed embodied in a boring device.

for coconut which comprises a tube member 1 having a sharpened edge 111 for boring at a first end 11 and a handle 2 screwed on a second end 12. The latter is provided on the lower end with an enlarged cross section 21. A striking member 3 slidably sleeved on the tube member 1 is limited to move upwardly by the handle 2; Striking member 3 is preferably formed by a hollow cylindrical central portion 31 and two enlarged cross section ends 31 1, 31 2. A flange element 4 is screwed on the tube 1 near a first end 1 The external diameter of tube 1 beneath the flange 4 is expanded to support the flange 4.

The outer surfaces of the handle 2 and striking member 3 are knurled so as to be easily grasped.

A rod member 8 having an end screwed with a head 5 and being biased to space from the handle 2 by a helical spring 9 fitted around the rod member 8 is inserted into the tube 1. The other end of the rod member 8 is covered by a cap 7 with a diameter corresponding to that of the expanded section of tube 1 beneath the flange 4 so that the movement of the cap 7 is limited by a shoulder portion 13.

The boring of coconut is operated manually by exerting an impact pressure successively on the flange 4 by the striking member 3 and the sharpened edge 111 of tube 23 will be driven into the shell as well as the fibrous exocarp of the coconut. The waste portion of coconut remaining in the tube can be pushed out by the cap 7 when pressing the head 5 against the helical spring 9.

A withdrawing device 6 for coconut adapted for use in combination with the boring device for coconut is disclosed hereinafter with reference to Fig. 3. A tube member 61 has about the same outer diameter as that of the tube 1 of boring device and a similar sharpened edge 63. A flange 62 is fixed to the tube member 61 in an appropriate position. A plurality of orifices 631 are provided on and distributed within a length of the tube wall which is sufficient to extend into, and expose the orifices to the interior space of coconut. When the sharpened edge is driven into the shell of coconut until the flange 62 abutting against the shell, the coconut milk contained can then be poured out through the tube member 61 by turning the coconut to a proper inclination.

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims which scope is to be accorded the broadest interpretation so as to encompass all such modification and equivalent structures.

1. A boring device for coconut, comprising: a tube member having a boring element at a first end thereof including a handle fixed to a second end and a flange element fixedly mounted around near said first end; a striking member capable of being operated by an external force to provide an impact action on said flange, slidably sleeved on said tube member whereby said boring element can be driven into the shell of coconut by the impact pressure applied to said flange element.

2. A boring device for coconut according to claim 1 , further comprising a longitudinal member having a head fixed at an end thereof slidably inserted in said tube member for extruding the waste portion of coconut cut off by said boring
