Definitions

  • the present invention relates to a prong tool.
  • Tools such as forks, pitchforks, etc. are known, which are equipped with one or more long and narrow teeth or prongs, usually named “tines", associated with a shank or ( handle.
  • tined tools in the form of large forks are used for instance for cooking food, in particular for cooking grilled food.
  • One of the drawbacks encountered when manufacturing such tined tools is the difficulty of reconciling the ability of the tool to retain the objects with the predisposition to release them when necessary.
  • a large kitchen fork for instance of the kind used for cooking grilled foods, must be capable of retaining the food, such as sausages, meat to be cooked on a skewer, etc. between the tines during cooking, and yet it must allow releasing the food without excessive difficulty, for instance for putting it on a tray.
  • the first characteristics is often favoured, in order to reduce the risk that the objects can be released, for instance by gravity or due to fortuitous impacts.
  • the tool predisposition to release the objects is unavoidably reduced, whereby it is often necessary to use a second tool, for instance of the same kind, in order to remove the object from the tines.
  • a first advantage of the invention is the possibility of moving the tines from an engagement configuration, in which the object is firmly retained on the tool, since the tines are parted or divergent, to a release position, in which the object can be removed from the tool.
  • the tines advantageously diverge by an angle of about 30° to 45° relative to the longitudinal axis of the handle.
  • the tool performance can be enhanced in respect of both the ability to retain the objects and the ability to easily release them without need to use other tools or supports.
  • FIG. Ia and Ib show a first exemplary embodiment of the invention, in idle and engagement configuration, respectively;
  • FIG. 2a and 2b show a second exemplary embodiment of the invention, in idle and engagement configuration, respectively;
  • - Figs. 3 a and 3b show a third exemplary embodiment of the invention, in idle and engagement configuration, respectively;

  • FIG. Ia and Ib there is shown a first exemplary embodiment of the tool according to the invention, generally denoted 11.
  • Tool 11 comprises an elongated flexible body formed by bending a metal wire, preferably stainless steel spring wire, so as to define a handle portion 11a and a pair of crossed tines lib, lie.
  • said tines are inclined by an angle of about 30° to 45° relative to the longitudinal axis of the handle portion.
  • Fig. Ia shows tool 11 in idle configuration, i.e. when no compression force is applied to handle 11a and tines 1 Ib, 1 Ic are not operating, with their respective ends 1 Id, lie close to each other.
  • Fig. Ib shows tool 11 in operating configuration, i.e. when a compression is transversally applied to handle 1 Ia in the direction indicated by arrows F to part tines 1 Ib, lie and cause their respective ends 1 Id, l ie, which preferably are pointed, to move away from each other.
  • the manner of using tool 11 is as follows.
  • Ends Hd, l ie of tines lib, lie are stuck into the body of the object to be seized with the tool, for instance a piece of meat to be grilled, while initially keeping tool 11 in the configuration shown in Fig. Ia.
  • handle 1 Ia is compressed in the direction indicated by arrows F, so as to make tines 1 Ib, lie part inside the body of the object, thereby firmly engaging it and making practically impossible for the tines to come out.
  • Hf, 1 Ig the inclination of which causes ejection of the object stuck onto the tool when the tines move back to the idle position.
  • tool 11 comprises a resilient rear portion 1 Ih, preferably defined by the bending of the wire from which the tool is obtained, which opposes the compression force applied onto handle 11a in the direction of arrows F, and allows therefore the tool 11 to autonomously resume the idle position shown in Fig,
  • FIGs. 2a and 2b there is shown a second exemplary embodiment of the invention, in which a tool 211, similar to the first one, is further provided with a coating 213 along the opposite arms of handle 211a.
  • Coating 213 is advantageously made of a flexible material, for instance plastics or rubber, at least in its rear portion, so as to follow the resilient flexion of curved rear portion 21 Ih of the wire the tool is made of.
  • the wire the tool is made of, preferably metal wire of spring stainless steel, defines tines 211b, 211c having points 21 Id, 21 Ie with curved end portions 21 If, 21 Ig, which cross so that the tine curvature is turned outwards from the tool in the operating configuration shown in Fig. 2b, and is turned inwards in the idle configuration shown in Fig. 2a. In this manner, the engagement with the object to be retained and the release thereof, respectively, are made easier.
  • tool 311 is made of bent wire, preferably spring metal wire of stainless steel, and is equipped with a stop 315 associated with handle 311a and limiting the handle extension determined by the resiliency of curved rear portion 31 Ih.
  • stop 315 is formed by a transverse member secured to one arm of handle 311a and it surrounds the opposite arm, thereby preventing the two arms from being spaced apart beyond a predetermined limit.
  • the wire forming tool 311 is advantageously covered with a coating 313 making the handle more comfortable.
  • Tines 31 Ib, 31 Ic moreover are pointed along the whole of their end portions 31 If, 31 Ig, in order they more easily penetrate into the objects to be seized.
  • tool 411 is obtained from a Y-bent wire, preferably spring stainless steel wire, associated with a support 417, for instance a base of wood or plastics, so as to be slidable between a retracted position, corresponding to the configuration shown in Fig.
  • support 417 is so shaped that it defines a handle portion 411a for grasping by the user.
  • support 417 can be inserted in a suitably shaped casing, having a handle and an opening through which the tines come out.
  • tool 411 by acting on handle rear portion 41 Ih, can take an engagement or operating configuration, shown in Fig. 4b, where tines 41 Ib, 41 Ic, preferably inclined by about 30° to 45° relative to the longitudinal axis of the handle, extend out of support 417 and their corresponding end portions 411 d, 411e are parted, and an idle configuration, where tines 411b, 411c are accommodated within support 417.
  • support 417 is equipped with a pair of oblique guides 419, arranged for instance to guide end portions 41 If, 411g of tines 411b, 411c during their sliding movement relative to support 417.
  • a central guide 421, secured to support 417, allows guiding the Y-shaped wire during its sliding movement relative to support 417.
  • the Y-bent wire can be associated with a drive knob accessible from the outside of the casing to allow making the Y-shaped wire slide relative to support 417.
  • a fifth exemplary embodiment of the invention in which tool 511, formed for instance by bending a steel wire, preferably of spring stainless steel, has a pair of crossed tines 511b, 511c of the kind disclosed with reference to the third embodiment of the invention.
  • the tines are preferably inclined by about 30° to 45° relative to the longitudinal axis of the handle portion but, as it can be better seen in Fig. 5b, they lie in a plane inclined, preferably by about 45°, with respect to the plane of tool handle 511a.
  • 51 Ig of tines 511b, 511c is particularly advantageous when the tool of the invention is used as a barbecue fork, since it allows seizing the objects, e.g. sausages, steaks, vegetables, etc., arranged on a flat surface, such as a grill or a tray, while keeping the hand in a substantially horizontal position, hence less exposed to heat or to hot oil sprays.
  • This exemplary embodiment also includes a coating 513 for making handle 511a more comfortable.
  • said coating 513 may also be made of rigid material, since it leaves resilient rear portion 51 Ih of the handle free and therefore it does not interfere with the resilient behaviour of the tool.
  • This exemplary embodiment also includes a stop 515 of the kind disclosed with reference to the third embodiment of the tool according to the invention.
  • Figs. 5c, 5d and 5e there are shown as many embodiments of a resilient member applied to tool 511 in order to determine the resilient force opposing handle compression or to increase the resilient force of rear portion 51 Ih in order to make release of the object from the tool easier, when the grasp on handle 51 Ia is released.
  • Fig. 5c shows a tool having a leaf spring 514a curved as an arc of a circumference, which is located in handle region 511a and has the concavity turned towards rear portion 511h of title tool.

  • Slide 625 has associated therewith a rod 627 bearing, at its forward end, a hook 629 equipped with tines 611b, 611c, preferably parted by about 30° to 45° relative to the longitudinal axis of the handle.
  • a first transverse plate 631 secured to guides 623 and having a central bore 633 for rod 627, allows guiding rod 627 during its longitudinal movement driven by the sliding of slide 625.
  • a coil spring 635 wound around rod 627 in correspondence of plate 631 and supported by a cup 637 secured to rod 627, allows bringing rod 627, and hence slide 625, back to the retracted position, corresponding to the retracted position of tines 61 Ib, 61 Ic.
  • a second transverse plate 639 is provided in correspondence with the forward end of guides 623 and has a pair of holes through which tines 61 Ib, 61 Ic pass.
  • a coating 613 is moreover provided on the elongated body in the region of handle 611a to facilitate the grasp on the tool and the drive of slide 625 with the thumb of the hand grasping the tool.
  • the sliding movement of slide 625 in the direction of arrow A causes tines 61 Ib, 61 Ic to completely come out through the holes provided in front plate 639, whereas the sliding movement of the slide in the reverse direction, denoted by arrow B, advantageously caused or assisted by return spring 635, brings tines 61 Ib, 61 Ic back inside guides 623.
