Description

DETACHABLE HANDLE FOR COOKING VESSELS

Technical Field

[1] The present invention relates to a detachable handle for cooking vessels, and more particularly, to a detachable handle for cooking vessels, which has a simple structure that the handle can be detachably mounted on cooking vessels of various kinds through a simple manipulation, and which can prevent accidents by preventing separation of the handle from the cooking vessels due to a user's carelessness, thereby enhancing convenience in use.

Background Art

[2] In general, cooking vessels such as pots or frying pans are used when a user heats and cooks foods using a heating device such as a burner or a gas range. Such a cooking vessel has a handle attached on a side or both sides for enabling the user to easily lift the heated cooking vessel and to easily carry it.

[3] However, since the handle is fixed on the cooking vessel, when the cooking vessel is heated at high temperature for a long time using the heating device, the heat of high temperature may be transmitted to the handle. In this instance, since the user may get burnt in the hand when the user grasps the handle with his or her hand, the user has to lift the cooking vessel using a dish cloth or a thick glove, and in this case, the user may frequently drop down the cooking vessel since the user grasps the cooking vessel in a unstable state.

[4] In addition, since the handle attached on the cooking vessel protrudes outwardly, the cooking vessel occupies a space unnecessarily during safekeeping and is unsanitary since foreign matters may be stained on the handle during washing.

[5] Meanwhile, since some of the cooking vessels, for instance, earthenware bowls, have no handle, separate nippers are equipped in restaurants for carrying the cooking vessels. However, if the nippers are not correctly fixed to the cooking vessel, in which cooked food is contained, since the nippers are inclinedly fixed to the circumference of the cooking vessel after the nippers are simply put on the circumference of the cooking vessel, if the nippers are not correctly fixed to the cooking vessel, in which cooked food is contained, the user may drop the cooking vessel, and in this instance, hot food is sputtered and may cause the user's burn. Moreover, if the user frequently carries the cooking vessels using the nippers in the restaurant, the user may frequently drop the cooking vessels due to reduction of the user's grasping power, and transmit excessive power to the user when the user uses the nippers for a long time, and so, the nippers cause inconvenience in use.

[6] Recently, to solve the above problems, a detachable handle which can be detachably mounted on a cooking vessel whenever it is needed after the handle is manufactured separately from the cooking vessel has been continuously developed. For an example, Korean Utility Model Registration No. 0,303,457 discloses a detachable handle for cooking vessels as shown in FIGS. 1 and 2.

[7] FIG. 1 is an exploded perspective view of a prior art detachable handle for cooking vessels, and FIG. 2 is a sectional view showing an assembled state of FIG. 1.

[8] The prior art detachable handle 100 for cooking vessels, as shown in FIGS. 1 and

2, includes a body part 110 having the inner space located longitudinally when upper and lower portions of the body part 110 are assembled with each other into one, a fixing part 120 mounted on the front end of the body part 110, a locking part 130 accommodated in the inner space of the body part 110, and a sliding part 140 mounted beneath the body part 110 via a support piece 143.

[9] The fixing part 120 has a fixing plate 121 formed on the front end thereof and bent downwardly. Moreover, the locking part 130 has a locking plate 131 formed on the front end thereof and bent downwardly, and a rack 135 and a stopping gear 136 are formed beneath the locking part 130 longitudinally in order. In addition, the locking part 130 further has an elongated slot formed on the upper surface thereof and a returning spring 133 mounted in the elongated slot.

[10] The sliding part 140 is generally in the form of a bar, and has a gear 141 formed on the top thereof and interacting with the rack 135.

[11] A wedge type stopper 151 is rotatably mounted on the body part 110 along a direction of plate surface, and a spring 153 and a releasing pin 152 are mounted on the body part 110 at both sides of a tail portion of the stopper 151. Here, the releasing pin 152 is mounted on the body part 110 in such a way as to be pressed from the outside.

[12] The prior art detachable handle for cooking vessels can be used to the cooking vessel by performing the following process. First, after the handle approaches the upper portion of the cooking vessel, the circumference of the cooking vessel, namely, a side of a jaw is inserted into the handle.

[13] After that, the handle 142 of the sliding part 140 is pressed backwardly, the rack

135 of the locking part 130 and the gear 141 of the sliding part 140 are interacted, and the locking plate 131 is moved toward the fixing plate 121. Here, the pressurizing action of the sliding part 140 is continued till the jaw of the cooking vessel is compressed by the locking plate 131 and the fixing plate 121. As described above, when the pressurizing action of the sliding part 140 is finished, the compression action of the locking plate 131 and the fixing plate 121 can be kept in stable by engagement (the engaged state is maintained by the spring) between the front end of the stopper 151 and the stopping gear 136 of the locking part 130, and thereby, the handle can be attached to the cooking vessel. [14] In the above state, when the user pressurizes the releasing pin 152, the engagement between the front end of the stopper 151 and the stopping gear 136 of the locking part 130 is released while the spring 153 is compressed.

[15] When the engagement between the front end of the stopper 151 and the stopping gear 136 of the locking part 130 is released, the locking plate 131 is returned to its original position by elasticity of the returning spring 131 mounted on the locking part 130, and thereby, the handle is separated from the cooking vessel.

[16] However, as described above, the prior art detachable handle for cooking vessel can properly regulate a separation distance between the fixing plate 121 and the locking plate 131 corresponding to the thickness of the circumference of the cooking vessel, but has the following problems.

[17] First, since the distance between the fixing plate 121 and the locking plate 131 is gradually changed by a saw pitch of the gear 141 formed on the sliding part 140, the prior art detachable handle cannot be stably applied to cooking vessels which do not have the circumference thickness not corresponding to the distance between the fixing plate 121 and the locking plate 131.

[18] Second, when the prior art detachable handle is used to the cooking vessel having a thick circumference, the handle may be tightly locked to the thick circumference, and in this instance, the detachable handle may not be separated from the cooking vessel in spite of the pressurizing action of the releasing pin 152.

[19] Third, since the releasing pin 152 is exposed to the side of the body part 110, when the user grasps the handle attached to the cooking vessel or due to the user's carelessness in a state where the user correctly grasps the handle, the releasing pin 152 may be pressurized. In this instance, since the cooking vessel is separated from the handle and drops down and hot food is sputtered in all directions, a burn may be caused.

[20] Fourth, the prior art detachable handle for cooking vessels has a complicated structure that the rack and the gear means are adopted to the locking part 130 and the sliding part 142 for operation of the handle.

[45] As shown in FIGS. 3 and 5, the detachable handle 10 for cooking vessels according to the present invention has a predetermined length so that a user easily grasps it with the hand, and has an ergonomic outward appearance. The handle 10 includes a body part injection-molded of synthetic resin. The body part is divided into an upper member 11 and a lower member 12, and the lower member 12 has coupling holes 12f and 12g respectively formed at the front end portion and the rear end portion thereof. The upper member 11 and the lower member 12 are assembled with each other by inserting and fastening coupling means 13 and 14 such as screws or bolts through the coupling holes 12f and 12g. Here, not shown in the drawings, but coupling holes respectively formed at the front end portion and the rear end portion of the upper member 11 are located at positions corresponding to the coupling holes 12f and 12g of the lower member 12, but, the coupling holes of the upper member 11 are not completely perforated but formed to a predetermined length from the lower surface of the upper member 11.

[46] A sliding part 20 which is detachable to the cooking vessel and made of metal is slidably mounted on the lower member 12 of the body part in a longitudinal direction.

[47] As shown in FlG. 4, the sliding part 20 includes a sliding plate 21 having predetermined length and thickness, a detachably piece 22 bent downwardly from the front end portion of the sliding plate 21, a fitting portion 22 protruding from the rear end portion of the sliding plate 21 for fitting an end of a first elastic spring 24 thereto, and stepped portions 2Ia-I and 21a-2 formed in such a way that both sides located between the front end portion and the rear end portion of the sliding plate 21 protrude outwardly.

[48] Here, a second elastic spring 24 mounted at the rear end portion of the sliding plate 21 always pushes the rear end portion of the sliding plate 21 forwardly, and the detachable piece 22 is in close contact with the inner circumference of the cooking vessel 50, and detachably combined to the cooking vessel 50 together with a stepped surface 12c of the lower member 12. The detachable piece 22 and the stepped surface 12c are inclined at a predetermined angle in order to enhance combining force to the cooking vessel 50.

[49] Furthermore, the sliding plate 21 includes a vertical guide hole 21b of a predetermined length formed on a side of the plate surface, on which the stepped portions 2Ia-I and 21a-2 are formed, and first and second horizontal guide holes 21c and 21d of a predetermined length respectively formed in front and rear directions from the vertical guide hole 21b. The second horizontal guide hole 21d has an approximately round hole 2Id-I (see FIG. 6) formed at the front portion thereof and a narrow guide hole 21d-2 extending longitudinally from the rear portion of the round hole 2Id-I to communicate with the round hole 2Id-I and being narrower than the round hole 2Id-I.

[50] Meanwhile, a rotary-type working part 30 is mounted at the front of the upper member 11 of the body part in order to easily and simply move the sliding plate 21 of the sliding part 20 in forward and backward directions in a state where the user grasps the body part.

[51] The rotary-type working part 30 includes: a disc type rotating portion 31 seated on the upper surface of the upper member 11 of the body part and having a through hole 31a formed on the center thereof and coupled with the coupling hole 1 Ic of the upper member 11 via coupling means 35 such as a screw or a bolt, the rotating portion 31 ; a pressurizing portion 32 directing from a side to the other side of the upper surface of the rotating portion and horizontally protruding from the other side of the rotating portion in a state where the pressurizing portion 32 is spaced apart from the upper surface of the upper member 11 ; and a support piece 33 formed on the bottom surface of the rotating portion 31 and inserted and supported to the vertical guide hole 21b of the sliding plate 21 through an arc-shaped hole 1 Ia-I formed on the upper member 11. As described later, it is preferable that the support piece 33 is accommodated in a bush 34 for preventing abrasion of the outer circumference thereof when the rotary-type working part 30 is rotated.

[52] By the above structure, when the user pushes the pressurizing portion 32 in the clockwise direction or pulls it in the counterclockwise direction by a simple manipulation using the thumb without applying great power in a state where the user grasps the body part of the detachable handle with one hand (for instance, when the user grasps the handle while the user's the back of the hand directs the right or the top of the handle, the detachable piece 22 of the sliding part 20 can be combined to or separated from the cooking vessel. [53] As described above, when the user applies pressurizing power to the pressurizing portion 32 of the rotary-type working part 30, the rotating portion 31 of the working part 30 slidably moves the sliding plate 21 in forward and backward directions while rotating to 90 ° in the clockwise or counterclockwise direction along the arc-shaped hole 1 Ia-I by the support piece 33 supported in the vertical guide hole 21c of the sliding plate 21 of the sliding part 20 based on the coupling means 35.

[54] For a smooth sliding action of the sliding plate 21 in forward and backward directions from the lower member 12. The lower member 12 has receiving recesses 12a-l and 12a-2 of a predetermine depth for receiving and seating the sliding plate 21 of the sliding part 20 thereon.

[55] Additionally, the first recess 12a-l of the receiving recesses has a width corresponding to the width ranging from the stepped portion 2Ia-I to the stepped portion 21a-2 of the sliding plate 21 and is longer than the stepped portions 2Ia-I and 21a-2, but the second recess 12a-2 is narrower than the first recess 12a-l and extends from the first recess 12a-l backwardly.

[56] Moreover, the receiving recesses 12a-l and 12a-2 have a structure that the first recess 12a-l has an arc-shaped groove 12b-l corresponding to the arc-shaped hole 1 Ia-I of the upper member 11 and being deeper than the first recess 12a-l so that an end portion of the support piece 33 of the rotary-type working part 30 is inserted and supported through the vertical guide hole 21b formed on the sliding plate 21 of the sliding part 20 and a mounting groove 12b-2 to which the first elastic spring 24 is mounted is formed from a side of the arc-shaped groove 12b-l toward the second recess 12a-2 and longer than the second recess 12a-2.

[57] The first elastic spring 24 is mounted in the mounting groove 12b-2.

[58] In addition, at the rear end portion of the upper member 11, a groove 1 la-2 (see

FIGS. 9 and 10) is formed in correspondence to the mounting groove 12b-2.

[59] Meanwhile, as shown in FIGS. 5 to 10, the pin member 40 includes: a pressing portion 40a inserted through the lower end portion of the first pin hole lib formed on the upper member 11 of the body part and exposed to the upper surface of the upper member 11 from the first pin hole 1 Ib, the pressing portion 40a having a ring-shaped holding jaw 4Oa-I held to the lower end portion of the pin hole lib; and a support portion 40b extending from the lower end portion of the pressing portion 40a, having the outer diameter smaller than the outer diameter of the pressing portion 40a, and inserted and supported to the second pin hole 12d formed on the lower member 12, the second elastic spring 41 being mounted on the outer circumference thereof.

[60] Moreover, a recess 40c is formed between the pressing portion 40a and the support portion 40b. The recess 40c is inserted into the second horizontal guide hole 21d of the sliding plate 21 and fit to the inner periphery of the second horizontal guide hole 2 Id. Furthermore, a ring-shaped jaw portion 4Od protrudes from the lower end portion of the recess 40c in a circumferential direction and has the outer diameter corresponding to the inner diameter of the round hole 2Id-I of the second horizontal guide hole 2 Id. The ring-shaped jaw portion 4Od prevents a forward movement of the sliding plate 21 by being held on the inner periphery of the round hole 2Id-I of the second horizontal guide hole 21d when the detachable piece 22 of the sliding part 20 is combined to the cooking vessel by the operation of the rotary-type rotating part 30.

[61] The pin member 40 serves as a stopper for preventing the forward movement of the sliding plate 21 of the sliding part 20 when the detachable piece 22 of the sliding part 20 is combined to the cooking vessel, whereby it can be surely prevented that the detachable piece 22 is separated from the cooking vessel 50. In addition, the pin member 40 also serves as a releasing pin for releasing the combined state between the detachable piece 22 of the sliding part 20 and the cooking vessel 50.

[62] In more detail, as shown in FIG. 6, when the user does not use the handle according to the present invention, namely, when the pressurizing portion 32 of the rotary-type working part 30 is located at right angles to the longitudinal direction of the body part, since the stepped portion 2Ia-I and 21a-2 of the sliding plate 21 are held at the front end portion of the first recess 12a-l of the lower member 12 by restoring force of the first elastic spring 24 elastically supported at the rear end portion of the sliding plate 21, the detachable piece 22 of the sliding part 20 protrudes forwardly in a state where it is spaced apart from the stepped surface 12c of the lower member 12. In this instance, as shown in FIGS. 6 and 10, the pin member 40 is caught at the end of the rear guide hole 21d-2 of the second horizontal guide hole of the sliding plate 21 by the recess 40c formed on the outer periphery thereof.

[63] In this state, to apply the handle of the present invention to the cooking vessel 50, in other word, to combine the detachable piece 22 of the sliding part 20 to the cooking vessel 50 (see FIG. 11), when the pressurizing portion 32 of the rotary-type rotating part 30 is rotated at 90 D in the counterclockwise direction, as shown in FIG. 7, the support piece 33 formed on the bottom surface of the rotating part 30 pushes a side wall of the vertical guide hole 21b backwardly along the arc-shaped hole 1 Ia-I and the arc-shaped groove 12b-l respectively formed on the upper and lower members 11 and 12, and thereby, the sliding plate 21 is moved backwardly while the first elastic spring 24 is compressed. In this instance, while the sliding plate 21 is moved backwardly along the first horizontal guide hole 21c and the guide hole 21d-2 of the horizontal guide hole by the coupling means 13 and the recess 40c of the second horizontal guide hole, the round hole 2Id-I of the second horizontal guide hole is in contact with the outer periphery of the second pin member 40 and the round hole 2Id-I and the pin member 40 are arranged at right angles to each other. Thereby, the pin member 40 is lifted upwardly to a predetermined distance (d), as shown in FlG. 9, by elasticity of the second elastic spring 41 mounted at the rear end portion thereof, and then, the outer periphery of the ring-shaped jaw portion 4Od of the pin member 40 is caught to the round hole 2Id-I with a sound of locking.

[64] Therefore, since the location of the sliding plate 21 is fixed by interaction between the ring-shaped jaw portion 4Od of the pin member 40 and the round hole 2Id-I, the sliding plate 21 is not moved forwardly, whereby the detachable piece 22 of the sliding part 20 can be firmly and securely combined to the cooking vessel 50.

[65] In addition, in the above combined state, as shown in FlG. 7, since the pin member

40 is covered by a hemispheric protrusion 32d protruding from a side of the pressurizing portion 32 of the rotary-type rotating part 30, there is no possibility that the user touches the pin member 40 through the user's carelessness, and also, the user cannot press the pin member 40 intentionally, so that the above combined state can be kept more safely.

[66] Meanwhile, when the detachable piece 22 of the sliding part 20 is combined to the cooking vessel 50, even though the pressurizing portion 32 of the rotary-type working part 30 is rotated to about 15 D in the clockwise direction by pressurizing force (see FlG. 8), the combined state is not released. That is, the rotary-type working part 30 can be freely rotated in a state where the pin member 40 is fixed at the round hole 2Id-I of the second horizontal guide hole even though the pin member 40 is rotated to about 15 D in the clockwise direction by the dimensional tolerance between the vertical guide hole 21b and the second horizontal guide hole 21d of the sliding plate 21.

[67] As described above, to release the combined state between the handle and the cooking vessel 50, first, the user rotates the pressurizing portion 32 of the rotary-type working part 30 to about 15 D in the counterclockwise direction, and then, presses the pin member 40 exposed by the rotation. Thereby, since the sliding plate 21 fixed by the pin member 40 is moved, the user second rotates the pressurizing portion 32 of the rotary-type working part 30 in the same direction. Therefore, in the state where the handle is combined to the cooking vessel 50, if the user does not want, the handle is never separated from the cooking vessel 50, and to release the combined state, the user has to manipulate the handle in two stages. So, the user can use the detachable handle of the present invention in more safe than the prior art.

[68] In addition, when the user converts the non-used state of the handle as shown in

FlG. 6 into the used state shown in FlG. 7 by the dimensional tolerance, once the user rotates the pressurizing portion 32 of the rotary-type working part 30 to about 75 D in the counterclockwise direction, the pin member 40 is completely caught to the round hole 2Id-I of the second horizontal guide hole of the sliding plate 21, so that the combined state can be kept securely. [69] As described above, it is preferable that the inner and outer surfaces of the detachable piece 22 is coated with silicon resin 22a (see FlG. 11) so as to prevent transmission of heat of high temperature to the detachable piece 22 by a heating device such as a burner or a gas range and to increase combining force against to the cooking vessel 50 when the detachable piece 22 of the sliding part 20 is combined to the cooking vessel 50.
