Definitions

  • the field of the present invention is tongs principally used for food items.
  • Tongs have long been used to handle hot food items in a kitchen environment.
  • Kitchen tongs commonly referred to as a pair of tongs, frequently employ two arms pivotally attached to one another at one end and having jaws at the other.
  • a resilient spring biasing the arms to an open position allows the user to conveniently compress the arms together to grip food items for manipulation and transport.
  • a lock to retain the two arms closed together principally for purposes of storage has been found useful.
  • Such locking mechanisms include simple rings which may be drawn along the arms of a pair of tongs away from the pivot until the arms are retained in close proximity.
  • the present invention is directed to a pair of tongs including pivotally engaged arms having jaws at one end and a pivotal engagement at the other.
  • a locking sleeve having a channel therethrough is slidable onto the arms about the pivotal engagement to retain the arms together in a locked position.
  • a closure cooperates with the locking sleeve to prevent juices and other cooking liquids from migrating down the arms and flowing from the pivotal end of the tongs.
  • the closure may be engageable for removal and cleaning and the locking sleeve helps to retain such liquids until cleaning.
  • the locking sleeve offers a flat surface perpendicular to a central axis for standing the pair of tongs vertically on a horizontal surface.
  • one or more tracks extend longitudinally in the channel of the locking sleeve.
  • the track or tracks can cooperate with an extended pivot pin of the pivotal engagement to limit the extent of movement of the locking sleeve and prevent its complete separation from the pair of tongs.
  • a stop may be provided at the other end of the channel adjacent the end closure and extending across the track or tracks. This position blocking the track or tracks prevents interference of the pivotal engagement end of the arms with the closure.
  • the stop may be an annular element having an opening which is conterminous with the channel to avoid blocking food elements carried along by cooking liquids. This stop extends across the track or tracks to also limit movement of the locking sleeve.
  • an outer profile on each arm is curved inwardly toward the pivotal engagement across which the one end of the locking sleeve slides onto the arms. This profile cooperates with the locking sleeve to reduce the travel of the locking sleeve between fully open and fully locked positions to better accommodate placement of the channel closure.
  • the pivotal engagement of the arms of the tongs includes a pin and oblong holes in the arms to receive the pin.
  • the arms are biased apart by a resilient element.
  • the channel of the locking sleeve is slidable onto the arms with the arms compressed toward one another at the pivotal engagement. With the arms released at the pivotal engagement, the arms can retain the locking sleeve with the arms in an angular range of closed positions and the locking sleeve is retained in position as well.
  • any of the foregoing separate aspects may be combined to further advantage. Accordingly, it is a principal object of the present invention to provide an improved pair of tongs. Other and further objects and advantages will appear hereinafter.
  • Figure 1 is perspective view of a pair of tongs.
  • Figure 2 is an exploded perspective view of the pair of tongs of Figure 1.
  • Figure 3 is a front end view of the pair of tongs of Figure 1.
  • Figure 4 is a cross-sectional view of the pair of tongs taken along the centerlines of the arms.
  • Figure 5 is a cross-sectional detail view of the pair of tongs showing a second embodiment of the cap on the locking sleeve.
  • Figure 6 is a cross-sectional detail view of the pivotal engagement.
  • Figure 7 is a cross-sectional view of the pivotal engagement taken along line 7-7 of Figure 5.
  • a pair of tongs generally designated 10, includes two elongate arms 12, 14 which are associated through a pivotal engagement at one end of the arms 12, 14. Jaws 16, 18 are located at the ends of the arms 12, 14 displaced from the pivotal engagement. These jaws are shown to be covered by temperature resistant silicone grips 20.
  • each arm 12, 14 includes two spaced apart lugs.
  • the lugs 22 of arm 12 are nested inwardly of the lugs 23 of arm 14 with holes aligned to receive a pin 24 therethrough.
  • the lugs 22, 23 with the pin 24 define the pivotal engagement.
  • the arms 12, 14 and the lugs 22 are arranged in this preferred embodiment to have 2mm gaps in the assembled pivotal engagement between elements to facilitate complete cleaning.
  • a resilient element 26 is wrapped about the pin 24 and extends to engage the inside surfaces of the arms 12, 14.
  • the element 26 is a formed plate spring including an arcuate mid section with radiating arms. The element 26 may be under some precompression with the radiating arms not fully released even with the pair of tongs in the fully open position.
  • a locking sleeve 28 is arranged at the pivot end of the pair of tongs 10.
  • the locking sleeve 28 is slidable onto the arms about the pivotal engagement.
  • a channel 30 extends fully through the locking sleeve 28.
  • the locking sleeve 28 and channel 30 define a central axis through the tongs 10.
  • the channel 30 in this embodiment is substantially square in cross section.
  • the end of the channel 30 toward the arms 12, 14 operates to engage the outer surfaces of the arms 12, 14 to force them toward one another as the locking sleeve 28 is moved onto the arms 12, 14.
  • the outer surfaces of the arms 12, 14 curve inwardly toward the pivot. This outer profile allows a wider, fully open position of the arms without having to fully withdraw the locking sleeve 28 from around the pivotal engagement.
  • the locking sleeve 28 includes tracks 32 on opposed sides of the channel 30. These tracks 32 receive the ends of the pin 24. The tracks 32 do not extend fully to the end of the channel 30 toward the arms 12, 14. In this way a stop is created at one end of the tracks 32. The stop thus created prevents the locking sleeve 28 from being disassembled from the pivotally engaged arms 12, 14 by interfering with the ends of the pin 24 riding in the tracks 32.
  • the holes 33 in the lugs 22, 23 through which the pin 24 extends, defining the pivotal engagement, are oblong in cross section.
  • the short dimension of these holes 33 is that of the diameter of the pin 24 with operative clearance.
  • the long dimension of the holes 33 is preferably less than twice the diameter of the pin 24. This dimension is best determined empirically as the outer profile of each arm 12, 14 and the size of the channel 30 impact the amount of compression of the arms 12, 14 toward one another for optimal operation.
  • the long dimension of each oblong hole 33 is oriented perpendicular to the elongate arm 12, 14 through which it extends.
  • An annular stop 34 is retained at the distal end of the locking sleeve 28. This annular stop 34 can be employed to prevent the two arms 12, 14 from moving too far through the channel 30. This stop 34 extends across the tracks 32 to engage the pin 24 moving in the tracks 32. The stop 34 is positioned to limit movement of the locking sleeve 28 to prevent interference of the pivotal engagement end of the arms 12, 14 with the closure, again, described below.
  • An opening 36 is provided through the middle of the annular stop 34. This opening 36 preferably has a surface which is conterminous with the channel 30 to avoid food items and other substances from becoming hung up in the channel 30.
  • the locking sleeve 28 can be moved relative to the arms 12, 14 to insure at least a 2mm gap therebetween for cleaning purposes.
  • the pin 24 may be more tightly constrained in the tracks 32; but it can be moved along the tracks 32 to facilitate cleaning.
  • the locking sleeve 28 can include a cup 38 to provide a closure at the end of the pair of tongs 10. This cup can slide over and close the channel 30 of the locking sleeve 28 with a resilient interfering fit and yet be removable for cleaning.
  • the sidewall 40 of the cup 38 provides this resilience. The sidewall 40 also becomes the retainer of cooking liquids as the cup 38 is taken from the locking sleeve 28.
  • the locking sleeve 28 and/or the closure of the locking sleeve 28, defined in the preferred embodiment by the cup 38, may have a surface 42 in a plane perpendicular to the center axis of the locking sleeve 28.
  • a surface 42 may be defined by the entire surface of the locking sleeve 28 or cup 38, an annular edge or raised portion thereon or even as little as three points in a triangular pattern all lying in a plane perpendicular to the center axis of the locking sleeve 28. This enables the pair of tongs 10 to be positioned vertically on a horizontal surface, advantageous for convenient manual purchase.
  • the locking sleeve 28 and cup 38 can retain cooking liquids which flow down the tongs when in that vertical position.
  • a plug 44 may be included to provide a controlled release of accumulated liquids from the channel 30 of the locking sleeve 28.
  • the tongs 10 may be stored with the locking sleeve 28 retaining the elongate arms 12, 14 together.
  • the resilient element 26 forces the arms 12, 14 outwardly at the pivotal engagement against the locking sleeve 28 which retains the sleeve 28 in place even if the elongate arms 12, 14 are pinched together.
  • the arms 12, 14 may be pinched together at the pivotal engagement to release the locking sleeve 28.
  • the locking sleeve 28 can be directly forced toward the end of the tongs 10 to release the arms 12, 14.
  • the arms 12, 14 can be pinched together at the pivotal engagement and the tongs 10 can be placed standing up on a horizontal surface.
  • the oblong holes 33 accommodating the compressing of the elongate arms 12, 14 toward one another at the pivotal engagement.
  • a user can easily grasp the closed tongs 10 resting vertically, open the tongs by squeezing the elongate arms 12, 14, employ the tongs 10 with the locking sleeve 28 held in the open position by the expanded arms 12, 14 under the bias of the resilient element 26 and then replace the tongs in rest position by squeezing the arms 12, 14 and setting the tongs down on the surface 42.
  • the tongs 10 will hold items at substantially all positions of the arms 12, 14 by advancing the locking sleeve 28 onto the arms 12, 14 with the arms compressed toward one another and then allowing the arms 12, 14 to expand apart under the bias of the resilient element 26 against the locking sleeve 28.
  • an improved kitchen pair of tongs has been disclosed. While embodiments and applications of this invention have been shown and described, it would be apparent to those skilled in the art that many more modifications are possible without departing from the inventive concepts herein. The invention, therefore, is not to be restricted except in the spirit of the appended claims.
