Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to accompanying drawings .

Accompanying FIGS. 1 to 3 are diagrams illustrating a construction of a detachable handle for cookware to be realized by the present invention.

As shown, the detachable cookware handle 100 of the present invention is detachably coupled to a lateral edge 52 of a vessel body 50 and is used for the purpose of safely moving the vessel body 50. The vessel body 50 has a space that is opened at its upper end in a cylindrical shape and can contain food inside. The detachable cookware handle 100 form an external form by a pair of handle bodies 10 divided as two parts of the same structure and coupled to each other by a bolt 11.

A catcher 12 is configured to bend downward at a front end of the handle body 10. A space 14 is provided inside the catcher 12 to fit the lateral edge 52 of the vessel body 50.

A guide groove 16 and a housing part 18 each are provided within the handle body 10.

An attachment/detachment means is built in the handle body 10 and detachably couples the handle 100 to the vessel body 50.

The attachment/detachment means includes a slider 20, a rotary part 28, an activation part 38, and a pressure part 42.

With being fitted into the guide groove 16 of the handle body 10, the slider 20 slides and moves along the guide groove 16 according to an operation that a user pulls a button part 22 formed at an upper end of the slider 20, thus withdrawing restriction on the rotary part 28. The slider 20 has a catching protrusion 24 at its front end. The catching protrusion 24 is inserted into a coupling groove 30 provided at an end of the rotary part 28 and restricts operation of the rotary part 28.

A coil spring 26 is installed within the guide groove 16 into which the slider 20 is fitted. The coil spring 26 is contracted with the movement of the slider 20 and then, at the same time when a pulling force for the button part 22 is released, is elastically expanded and restores the slider 22 to an initial state.

The rotary part 28 is fitted and coupled by a hinge 32 to the housing part 18 provided to open its upper end in the handle body 10. The rotary part 28 rotates centering on the hinge 23 according to an operation of the slider 20 and operates the activation part 38 and the pressure part 42 that extends from the activation part 38. A coupling groove 30 is provided through depression at an end of the rotary part 28 and fits the catching protrusion 24 of the slider 20.

A first spring 34 is fitted to the hinge 32 coupled to the rotary part 28. The first spring 34 is caught at its one end by the rotary part 28 and is caught at the other end by the handle body 10. In this state, the first spring 34 generates a tension force and automatically rotates the rotary part 28, at the same time when the catching protrusion 23 of the slider 20 is released from the coupling groove 30 of the rotary part 28. An insertion part 36 is provided through depression in front of the rotary part 28. A stopper 37 is protruded and formed at one side of the insertion part 36.

The activation part 38 is fitted into the insertion part 36 provided in front of the rotary part 28. In this state, the activation part 38 operates in combination with rotary operation of the rotary part 28 and pulls the pressure part 42 that presses the lateral edge 52 of the vessel body 50 inside. The activation part 38 is coupled at its one end to the hinge 32 coupled to the rotary part 28. The activation part 38 has a connection fragment 40 extended and formed at its lower end. The pressure part 42 is integrally extended and formed at a front end of the connection fragment 40. The activation fragment 38 is fitted into the insertion part 36 of the rotary part 28 and is caught at its one side by the stopper 37 of the rotary part 28. In this state, if the rotary part 28 rotates and operates, the activation fragment 38 rotates and operates centering on the hinge 32 together and pulls the pressure part 42 inside.

The pressure part 42 is integrally extended at a front end of the connection fragment 40 formed at a lower end of the activation part 38 and is bent downward. The pressure part 42 has a greater width than the connection fragment 40 and is positioned in the space 14 provided inside the catcher 12 of the handle body 10. If the activation part 38 rotates centering on the hinge 32, the pressure part 42 is pulled inside and fits the lateral edge 52 of the vessel body 50 into the space 14 inside the catcher 12. If the activation part 38 is restored to an initial state, the pressure part 42 is pushed outside and presses a circumference surface 52a of the lateral edge 52 of the vessel body 50 that is fitted into the space 14 inside the catcher 12. Although the vessel body is manufactured to have a lateral edge of a great thickness, the pressure part 42 can press the thickly manufactured lateral edge of the vessel body by a tension force of a second spring 44 described later, thus being capable of coupling the handle 100 irrespective of the kind of the vessel body.

The second spring 44 is separately installed in the connection fragment 40 at which the pressure part 42 is extended and formed. In construction, the second spring 44 is caught at its one end by an end of the connection fragment 40 and is caught at the other end by the rotary part 28. When the pressure part 42 is pushed back due to a thickness difference in a process of coupling the handle 100 to the vessel body 50 whose lateral edge is thickly manufactured, the second spring 44 elastically supports the pressure part 42. By doing so, the second spring 44 presses and fixes the pressure part 42 to the circumference surface 52a of the lateral edge 52 of the vessel body 50, thus being capable of coupling the handle 100 of the present invention. Its detailed description is made below in the following operation description. A process of coupling a detachable handle for cookware according to the present invention is described below with reference to FIGS. 4A and 4B.

As shown in FIG. 4A, if the button part 22 is pulled so as to couple the cookware handle 100 of the present invention to the vessel body 50, the slider 20 moves back along the guide groove 16 of the handle body 10 and releases the inserted catching protrusion 24 of the slider 20 from the coupling groove 30 of the rotary part 28.

Simultaneously, the rotary part 28 coupled by the hinge 32 with the handle body 10 rotates centering on the hinge 32 by a tension force of the first spring 34 fitted to an external diameter of the hinge 32, and is lifted upward.

With being caught by the stopper 37 of the rotary part 28, the activation part 38 fitted into the insertion part 36 provided in front of the rotary part 28 rotates centering on the hinge 32 together in combination with the rotary operation of the rotary part 28. Accordingly, the pressure part 42 connecting with the activation part 38 through the connection fragment 40 is pulled inside according to the rotation of the activation part 38.

Next, as shown in FIG. 4B, the lateral edge 52 of the vessel body 50 is fitted into the space 14 provided inside the catcher 12 of the handle body 10. In this state, if the rotary part 28 is pressed, the rotary part 28 rotates centering on the hinge 32 and is restored to the initial state .

At the same time when the rotary part 28 is restored, the slider 20 slides and moves to the front by a tension force of the coil spring 26 and inserts the catching protrusion 24 provided at a front end of the slider 20 into the coupling groove 30 of the rotary part 28, thus fixing the rotary part 28. By doing so, the rotary part 28 maintains the initial state without being lifted although a tension force according to contraction of the first spring 34 acts.

Next, according to an initial restoration operation of the activation part 38 that operates in combination with the rotary part 28, the pressure part 42 is pushed outside and then, presses the circumference surface 52a of the lateral edge 52 of the vessel body 50 fitted into the space 14 inside the catcher 12 of the handle body 10, thereby coupling the handle 100 to the vessel body.

Meantime, the vessel body 50 is manufactured to have a lateral edge of a diversity of thickness depending on its kind. For instance, when it is intended to couple the handle 100 of the present invention to a vessel body 150 manufactured to have a thick lateral edge 152, as shown in FIG. 5, the pressure part 42 is pushed back by a thickness of the lateral edge 152 of the vessel body 150 at the same time when the handle 100 is coupled to the lateral edge 152 of the vessel body 150, and rotates the connection fragment 40 and the activation part 38. At this time, the second spring 44 caught by the connection fragment 40 elastically supports the back movement of the pressure part 42, thereby being able to firmly couple the handle 100 of the present invention on the vessel body 50 or 150 manufactured at a diversity of thickness, irrespective of a thickness.

While the present invention has been described and illustrated herein with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made therein without departing from the spirit and scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of this invention that come within the scope of the appended claims and their equivalents .
