SEPARABLE COUPLING BETWEEN A HANDLE AND POTS AND PANS

Abstract: A removable coupling between a handle (14) and a pan (12) comprises a first member (11) fixed to the pan and a second member (13) fixed to the handle. The first member (11) comprises a projecting bracket (15) with a hole (16) therein and the second member (13) comprises a tongue (17) to be inserted in said hole (16) to lie parallel with and beneath the bracket. A cam member (19) is present in the second member (13) and is rotatable towards a locking position to press with its first cam surface (23) on an edge (25) of said hole (16) to scarf the bracket (15) between the first cam surface (23) and a facing projection (20) of the second member (13).

Description: "SEPARABLE COUPLING BETWEEN A HANDLE AND POTS AND PANS" The present invention relates to a separable coupling for removable engagement of a handle with a pan. The term • pan' refers to any utensil such as pans, casseroles, true pots and pans et cetera. The general purpose of the present invention is to make available a coupling low in cost, safe and easy to handle. In view of this purpose it is sought to provide in accordance with the present invention a removable coupling between a handle and a pan comprising a first member fixed to the pan and a second member fixed to the handle with the first member comprising a projecting bracket with a hole passing through it and the second member comprising a tongue which is inserted in said hole to traverse it and lie parallel with and beneath the bracket and a cam member is present in the second member and is rotatable towards a locking position to press with its own first cam surface on an edge of said hole to scarf said bracket between said first cam surface and a facing projection of the second member. TO clarify the explanation of the innovative principles of the present invention and its advantages compared with the prior art there is described below with the aid of the annexed drawings a possible embodiment thereof by way of non-limiting example applying said principles. In the drawings : - Fig. 1 shows a diagrammatic perspective view of a device in accordance with the present invention for coupling between a pan and a handle, - Fig. 2 shows a bottom view of the coupling of Fig. 1, and - Fig. 3 shows a cutaway view along plane of cut III-III of Fig. 2. With reference to the figures a coupling indicated as a whole by reference number 10 comprises a first engagement member 11 fixed on the pan 12 and a second member 13 fixed to the handle. The rest of the pan and the handle can have any known form and will not be further shown or described here. The member 11 has a rectangular bracket 15 projecting laterally from the pan and having a generally rectangular hole 16 for passage of a tongue 17 projecting forward from the second member 13. The second member 13 also comprises a cam member 19 driven by a lever 18 through a pin 27. As shown in Figs . 2 and 3 the engagement member on the handle has the front tongue 17 offset downward and has an extension permitting passage through the rectangular hole 16 in the engagement part fixed to the pan to lie parallel to and beneath the latter. The engagement part fixed to the handle has a rear projection 20 designed to be a striker for the leading edge 21 of the part 15 and a parallel front projection 24. The cam member 19 rotates between the front and rear projections 20, 24 and has a first cam end 22 and a second cam end 23 opposite. Upon rotation of the lever (18) towards the engagement locking position the cam member 19 moves from the broken line position to the solid line position shown in Fig. 2. The cam surface 22 presses against the front edge 24 while the cam surface 23 presses against an opposite rounded edge 25 of the hole 16 so as to press the edge 21 of the bracket 15 against the surface 20. The bracket thus is scarfed between the cam surface 23 and the projection 20. This prevents handle and pan movements against each other. The cam surface 22 prevents excessive stress on the pin 27. The cam 23 has a step 26 which in the locking position moves beneath the edge 25 so as to make withdrawal of the part 17 from the part 15 impossible. Advantageously in the releasing position the lever 18 projects laterally to the handle while in the locking position it is parallel to and inside the handle with the upper part projecting for movement to the releasing position. It is now clear that the preset purposes have been achieved. In the releasing position (Fig. 1) the handle is easily engageable with or disengageable from the pan while a simple rotation of the lever (18) towards the locking position (Figs. 2 and 3) ensures steady coupling with no possibility of even the smallest reciprocal movements. To reduce costs the first and second members can be advantageously made from blanked and bent sheet metal. Naturally the above description of an embodiment applying the innovative principles of the present invention is given by way of non-limiting example of said principles within the scope of the exclusive right claimed here. For example although the front engagement shown in the figures is preferable the engagement between the parts and the cam action direction can be different e.g. transversal to the handle extension as readily imaginable to one skilled in the art. The cam could also press from the outside of the bracket instead of from the inside of the hole therein. In addition the coupling members can be provided by die casting, pressing, blanking et cetera and of different materials. The tongue member can also be in a single piece with the handle. The handle itself can be of any shape and not necessarily the elongated type. For example it can be of the hand lever type. It is also possible to provide an interchangeable elongated handle and a hand lever on the same pan.

Claims: CLAIMS 1. Removable coupling between a handle (14) and a pan (12) comprising a first member (11) fixed to the pan and a second member (13) fixed to the handle with the first member (11) comprising a projecting bracket (15) with a hole (16) passing therein and the second member (13) comprising a tongue (17) to be inserted in said hole (16) to traverse it and lie parallel with and beneath the bracket and a cam member (19) is present in the second member (13) and is rotatable towards a locking position to press with its first cam surface (23) on an edge (25) of said hole (16) to scarf said bracket (15) between said first cam surface (23) and a facing projection (20) of the second member (13). 2. Coupling in accordance with claim 1 characterized in that the cam member (19) has a second cam surface (22) opposite the first and pressing when in locking position on a surface (24) of the second member which is opposite said projection (20). 3. Coupling in accordance with claim 1 characterized in that the cam member (19) has a step (26) beneath the first cam surface (23) and lies in locking position beneath the edge (25) of the hole (16) on which the first cam surface (23) presses. 4. Coupling in accordance with claim 1 characterized in that the edge (25) of the hole on which the first cam surface (23) presses is opposite the tongue (17) projecting from the second member. 5.
