Definitions

  • This invention relates to a device for cutting a coconut, and in particular, to a device for cutting a coconut into two approximately equal halves with minimal manual input.
  • coconut is the fruit of the coconut palm. It is made up of a thick fibrous fruit coat known as the husk, a hard protective endocarp or shell (hereafter called shell) and a fleshy middle layer known as the kernel. While the present invention may be used with both husked and de-husked coconuts, the term "coconut” is generally used herein to refer to a de-husked coconut.
  • the shape of a de-husked coconut varies from elongated oval to almost spherical, with variation in length and width.
  • the coconut has three eyes at one end and a seam running between any two of the eyes to the opposed end.
  • the two opposed ends of the coconut can be considered its "poles” and a line around its circumference equidistant between the poles its “equator”. If a cut is made along this "equator” the coconut is cut into two approximately equal halves.
  • domestic methods for cutting a coconut into two halves include hitting the coconut with a heavy knife or hitting the coconut against a hard surface.
  • a device for cutting a coconut comprising a support structure; a coconut clasper, movably mounted on the support structure, the coconut clasper including at least a pair of opposed jaws, to clasp opposing ends of a coconut, each jaw of the pair of opposed jaws being rotatable about an axis to permit rotation of the coconut clasped between the pair of opposed jaws; a cutter, mounted on the support structure for cutting the coconut clasped between the pair of opposed jaws; and a drive arrangement for driving the coconut, wherein the drive arrangement comprises at least one driving gear, structured to operationally mesh with at least one jaw of the pair of opposed jaws, to regulate controlled rotation of the coconut relative to rotation of a cutting blade of the cutter.
  • each jaw of the pair of opposed jaws of the coconut clasper comprises: a jaw base, connectable to a clasper body; a jaw back, rotatably secured to the jaw base; and a jaw gear abutting the jaw base and the jaw back, the jaw gear being connectable to the jaw back and mesh with the at least one driving gear, wherein rotation imparted by the at least one driving gear to the jaw gear rotates the coconut clasped between the pair of opposed jaws.
  • the coconut clasper comprises at least one guide spring unit connectable to the jaw back, wherein the at least one guide spring unit comprises: a guide spring shaft circumferentially seated in a cavity defined in the jaw back; and a guide spring, mounted on the guide spring shaft, the guide spring being configured to urge the coconut onto to the coconut clasper.
  • the guide spring comprises a guide spring top and a guide spring bottom, forming a predefined profile about a lateral direction of the jaw gear, wherein, the guide spring bottom is configured to urge the coconut along an axial direction of rotation of the pair of opposed jaws, and the guide spring top is configured to urge the coconut in a radial direction of rotation of the pair of opposed jaws, such as to securely hold and align the coconut in the pair of opposed jaws.
  • the jaw gear of each of the pair of opposed jaws is defined with gear teeth to mesh with gear teeth of at least one driving gear for controlled rotation of the coconut in the coconut clasper in a direction opposite to the direction of rotation of the cutting blade.
  • a length of the at least one driving gear is structured such as to maintain engagement of the gear teeth of at least one driving gear with each gear teeth of the jaw gear even when the pair of opposed jaws are farthest and closest from each other, while the pair of opposed jaws clasp opposing ends of the coconut.
  • a depth of each gear teeth of at least one jaw gear and a depth of each gear teeth of at least one driving gear are structured such as to maintain engagement with each other even when a distance between respective jaw gear and the at least one driving gear varies as the coconut clasper moves vertically up and down the support structure, while the cutting blade is engaged with the coconut to cut it.
  • the jaw gear of each of the pair of opposed jaws is engageable by a slotting spring
  • the slotting spring comprises: a spring stem laterally fixed to the jaw gear of the coconut clasper; and a spring bulb extending from the spring stem, the spring bulb resiliently deforms between at least two gear teeth of the jaw gear, wherein deformation of the spring bulb maintains alignment of the gear teeth of one jaw gear of one of the pair of opposed jaws with gear teeth of another jaw gear of other jaw of the pair of opposed jaws.
  • the cutting blade is coupled to a driving member.
  • at least one driving gear is operable by at least one of an actuator, the driving member, and a handle.
  • the support structure includes a clasper body slider, to receive and vertically guide the coconut clasper relative to the cutter, such as to vertically align the coconut in the pair of opposed jaws with the cutting blade of the cutter.
  • the device further comprises a reduction mechanism engageable between the driving member and the at least one driving gear, wherein the reduction mechanism is structured to step down a rotational speed of the coconut to less than a speed of rotation of the cutter.
  • the jaw base of the coconut clasper is defined with a connecting portion, connectable to the support structure.
  • the jaw back and the jaw gear are defined with a jaw gear hole to align the gripping unit and impart rotational movement of the jaw gear to the jaw back.
  • a device for cutting a coconut comprising a support structure; a coconut clasper mounted on the support structure and having a pair of opposed jaws, hereinafter also replaceably referred to as “jaws" or “opposed jaws', adapted for clasping opposed ends of a coconut, each jaw being rotatable about an axis to permit rotation of a coconut clasped in the jaws; and a cutter mounted on the support structure and positioned for cutting a coconut clasped in the jaws, wherein the device includes a coconut centring mechanism to cause simultaneous movement of the jaws to align the mid-point of the coconut clasped in the jaws with position of the cutter, such that, in use, the cutter acts at approximately the mid-point of the coconut.
  • the coconut clasper hereinafter also replaceably referred to as “clasper”, mounted on the support structure is able to move linearly in direction either perpendicular or substantially perpendicular to axis of rotation of the jaws.
  • Such movement of the jaws allow for the coconut clasper to move linearly in direction perpendicular or substantially perpendicular to axis of rotation of the jaws while the coconut is being cut.
  • This linear movement of the coconut clasper is needed in order to accommodate variability in shape and/or dimension of the coconut along its equator while the coconut rotates when being cut along the equator and also for the cutting blade to enter the shell while the coconut is being cut.
  • a simple device in accordance with the invention is able to clasp the coconut and cut it into two approximately equal halves with minimal manual input.
  • the cutter is preferably structured so as to cause rotation of the coconut clasped in between the jaws as it acts on the coconut. This may, for example, be achieved with a circular cutting blade. Rotation of the coconut as the cutter acts on it enables the cutter to cut along entire circumference of the coconut without changing position. Rotation by the cutter also eliminates need for motorized or manual rotation of the coconut. Alternatively, the coconut may be rotated by means including at least one of a manual rotating handle, a driving member, an actuator and a motor.
  • the cutter may include driving teeth as well as cutting teeth, the cutting teeth being structured and arranged so as to cut through the coconut, and the driving teeth being adapted to engage with the surface of the coconut clasped in the jaws such as to cause the coconut to rotate at a predetermined speed.
  • the driving teeth can also be configured to engage with the opposed jaws of the coconut clasper such as to cause the jaws to rotate the coconut at a predetermined speed.
  • the opposed jaws may include jaw gears which are engaged to control gears. The control gears being adapted to engage with the jaw gears of the opposed jaws such as to cause the coconut to rotate at a predetermined speed.
  • control gears and/or the jaw gears can derive power to rotate from the same source as that driving the cutter or from a different source which is motorised or manual. It will be appreciated that controlled rotation of the coconut is important to ensure that entire circumference of the coconut is cut by a cutting blade of the cutter.
  • the coconut clasper can have a slotting spring in order to ensure the teeth of both the jaw gears are in perfect mirror alignment with each other.
  • Such alignment of the jaw gears ensures that the teeth of each of the jaw gears are aligned with the teeth of the opposed jaws and engage at the same angle with the cutter engage gears, which mitigates twisting between the coconut and the opposed jaws while engaging.
  • the cutter preferably includes adjustable limiting means structured so as to limit depth of cut that the cutting blade may cut into the coconut clasped in the jaws.
  • adjustable limiting means can be configured, for example, to ensure that kernel of the coconut is not cut through, thus retaining the water in the coconut.
  • preservation of the kernel structure also means that the coconut can remain securely clasped in the jaws of the coconut clasper, even after the shell is cut through.
  • the coconut clasper mounted on the support structure could have small slack to allow it to wobble while being cut.
  • the coconut clasper may include a locking means adapted to reversibly lock the opposed jaws in a clasping position.
  • the locking means comprises a ratchet and pawl mechanism to allow controlled and incremental tightening of the opposed jaws.
  • the coconut clasper may include a release mechanism, resiliently biased such as to cause the opposed jaws to separate.
  • the release mechanism preferably comprises a spring arranged such that it is compressed as the opposed jaws are brought together.
  • the coconut centering mechanism may comprise a rack and pinion mechanism. When a rack and pinion mechanism is used, simultaneous movement of the opposed jaws is smooth and easily controlled.
  • the opposed jaws may be mounted on the rack and pinion mechanism such that one or both of the jaws is detachable.
  • the opposed jaws may be shaped such as to permit the opposed ends of a coconut to be visible when the coconut is clasped in the jaws. This may, for example, be achieved using ring-shaped jaws. When ring- shaped jaws are used, the user can align the coconut by centring the poles of the coconut in the middle of the ring.
  • the opposed jaws may include guide springs structured and arranged such as to grip the coconut tighter in a direction perpendicular to the axis of rotation of opposed jaws when the opposed jaws are brought together as well as create a pressure linearly between the opposed jaws and coconut, a kind of urging mechanism.

  • Support structure 300 has a slide support 301 and from below support base 302
  • rotational source power shaft 303 provides the rotational power needed to power the cutter and the other rotating parts.
  • This rotational power can be any source.
  • Rotational source power shaft 303 is connected to a first bevel gear 204a, a second bevel gear 204b and a bevel gear shaft 204c.
  • the bevel gear shaft 204c is connected to cutting blade 201 in a tight fit and it rotates at high speed.
  • the bevel gear shaft 204c passes loosely through limiting roller 202 so that it doesn’t rotate but when a coconut is being cut by the cutting blade 201 it limits the depth to which the cut is made. The difference between the radius of the cutting blade 201 and limiting roller 202 will limit the depth to which the coconut is cut. Ideally it is recommended to just cut the shell of coconut 10 and not the kernel. This ensures water does not leak out of coconut 10.
  • the rotational source power shaft 303 also connects worm gear set 205 which reduces the rotational speed considerably and is connected to a driving gear 203 through a gear set 207.
  • a driving gear shaft 208 connects both the driving gear 203 so they rotate in sync.
  • This arrangement ensures that the cutting blade 201 , which is used to cut coconut 10, rotates in high speeds which is recommended in the range of 1000 to 30000 rpm and driving gear 203, which is used to rotate the coconut 10 to be cut at a controlled speed rotates at speeds in a recommended range of 60 to 600 rpm.
  • Step 1 Referring to figures 10-11 which illustrates how a coconut 10 is placed between opposed jaws 115 of coconut clasper 100 and when moved towards each other the coconut is clasped between them. As explained earlier this is done with the combined support of the guide spring 115_5 and the lock lever 101_3. Let us call this coconut clasper 100 loaded with coconut 10.
  • depth of each gear teeth of at least one jaw gear 112_2 and depth of each gear teeth of at least one driving gear 203 are structured such as to maintain engagement with each other even when distance between respective jaw gear 112_2 and the driving gear 203 vary as the coconut clasper 100 moves linearly, i.e. in vertical direction, up and down the support structure (300), while the cutting blade 201 is engaged with the coconut 10 during cutting operation. This is structured to accommodate the largest and smallest coconuts.
