Description

DEVICE FOR ATTACHING A CONNECTOR MEMBER TO A HANDLE OF A KITCHEN CONTAINER The present invention relates to a device for attaching a connector member to a handle of a kitchen container. Kitchenware handles, particularly those made of heat-curing resin such as bakelite, are known to be connected to the cooking vessel by means of a metal connection means, which is attached to the handle and then connected to the container. cook by means of screws or rivets. Various devices for fastening the connecting member to the handle are known. A connecting member, known for example, has a beveled portion for connecting the cooking vessel; and an open section collar portion fitted in the connection portion of the mangt. , and having two end edges side by side bent into respective grooves formed in an upper face of the connecting portion of the handle. Below, the connecting portion has a slit within which a clamping member, in particular a blade that cuts into the side wall of the collar portion, is permanently pressed and deformed. These and other similar solutions have the disadvantage of producing a handle in which the collar portion of the 52/384 connection is interrupted (open) and therefore unsightly. Nor is this type of solution completely satisfactory in terms of speed, and ease of assembly. It is an object of the present invention to provide a device for fastening a connecting member to a handle of a cooking vessel, designed to eliminate the aforementioned disadvantages of the known art. More specifically it is an object of the present invention to provide a device that is easy, fast, and economical to produce and assemble, while at the same time being fully efficient. In accordance with the present invention, a device is provided for attaching a connecting member to a handle of a cooking vessel as defined in claim 1. The device accor to the invention provides efficiency, safety, reliability to hold the connection member to the handle. The clamping operation itself is also quick, easy and economical. Particularly on account that the reconnecting member is adjustable in advance to the connection portion of the handle by means of the preassembly tooth, and thus is secured to the handle even before it is fully clamped by pressing a permanently deformable clamping member. . Moreover, the resulting handle has a connecting member in the form of a highly attractive continuous closed band. The invention also relates to a connecting member for connecting a handle to a cooking vessel, and to a cooking vessel handle assembly, as defined in the accompanying claims 12 and 19 respectively. A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which: Figure 1 shows an exploded perspective view of a kitchen container handle assembly comprising a handle and a connecting member, and having a device for securing the connecting member to the handle accor to the invention; Figure 2 shows a large-scale section of a detail of figure 1 of assembled handle assembly; Figure 3 shows a perspective bottom side view of the connection member forming part of the handle assembly of Figure 1; Figure 4 shows a plan view of the underside of the connection member of figure 3; Figures 5 and 6 show sections along lines V-V and VI-VI in Figure 4 respectively; Figure 7 shows a section of an alternative embodiment of the handle assembly accor to the invention; Figure 8 shows a plan view of the underside of the connecting member forming part of the handle saddle of Figure 7. With reference to Figures 1 and 2 a handle assembly 1 of a known cooking vessel (for example a frying pan, not shown) comprising a handle 2, a connecting member 3 for connection to the cooking vessel, and a holding device 4 for holding the connecting member 3 to the handle 2. The handle 2 comprises a handle portion 5, in any form, designed to be held in use by a user (the example shown relates to a fry pan handle, a substantially elongated handle portion is shown); and a connecting portion 6 projecting from one end of the handle portion 5 along an axis A. The handle 2 is made, for example, of a heat-curing resin (such as Bakelite) or other suitable material. . The connecting portion 6 has a root end 7 located centrally on a front surface 8 of a handle portion 5; and a free end 9 opposite a root end 7. The handle 2 has an axial shoulder 10 facing the connecting portion 6 and is defined by an external annular edge radially around the root end 7 on the front surface 8. The The connection portion tapers along the axis A towards the free end 9, ie it reduces in the cross section from the root end 7 to the free end 9.

The connecting portion 6 is substantially prismatic with rounded sides and / or edges. More specifically, the connecting portion 6 comprises two opposite faces 11, 12 connected by two sides 13 and both faces 1 '11, 12 and the sides 13 converge towards the free end 9. The faces 11, 12, respectively, have a chair 15 and a diametrically opposite recess 16, both formed in the connection portion 6; the chair 15 has an entrance 17 facing the free end 9; and recesses 16 which are joined by 2 facing walls 18 crosswise to the axis A. The connecting member 3 comprises a collar portion 20 and a beveled portion 21. Referring also to FIGS. 3 to 6, the collar 20 m extends along axis A, and has an open interior cavity 22 extending along axis a and having two axially opposed openings 23 24 joined by respective end edges 25, 26. The collar portion 20 is tapering along the axis A, i.e. it has an inner cross section that reduces along the axis a, in particular from the end edge 25 to the end edge 26. The cavity 22 is in the same way as the connecting portion 6, which is inserted into the cavity 22. The collar portion 20 fits within the connecting portion 6, preferably with a small amount of interference, such that the outer edge 25 rests against the shoulder 10. The member of with Exion 3 is slightly radially flexible, and is preferably made of metal. More specifically, the connecting member 3 is a one-piece member that cuts from the metal sheet and has a slit-like shape. The collar portion 20 has a side wall 30 which defines the cavity 22 and is defined in itself by a slit band and has two opposite end tabs 31, 32; side walls 30 are grouped to define cavity 22 and the two tabs 31, 32 are joined to each other. In a non-limiting example shown, the tabs 31, 32 are joined by a fastener 33 carried by the tongue 31, and which engages a groove formed in the tongue 32. The tongue 32 slots within the cavity 22 to form a step 35 which it has slot 34; and a tongue 31, which supports the fastener 33, is super imposed on the tongue 32 in the step 35, such that it is substantially fluid with an external surface 36 of the side wall 30. The fastener 33 projects inwardly from the side wall 30 within the cavity 22 to define a preassembly tooth 37 that engages the chair 15. Obviously, the tabs 31, 32 can be joined in another way to that described here, for example when gluing, forming and welding, overlapping, or hook; and pre-assembling the teeth 37 which can be formed in a different manner as described and illustrated here by way of example, for example, can be applied and welded to the tongues 31, 32. The connecting member 3 also comprises a clamping member of permanently deformable pressure 38. More specifically, the clamping member 38 is defined by a sector 39 of the side wall 30 joined by one or more grooves 40 formed through the side wall 30. In a non-limiting example shown in the figures 3 to 5, the sector 39 is joined by two substantially parallel grooves 40a, 40b cross-shaped to the axis A. According to one aspect of the invention the groove 40a is closer to the end edge 26 and the beveled portion 21 that is curve along the axis A, with its end edge facing the concavity 26 and the beveled portion 21, and therefore faces a connecting end by which the connecting member 31 is connected to the recipient e cooking. In the example shown, the side wall 30 has two opposite sides 41, 42 connected by two sides 43, and both sides 41, 42 and sides 43 converge from the end edge 25 towards the end edge 26, the preassembly teeth 37 , defined by the bra 33, are located on a side 41 to engage the chair 15, and hold the member 38 which is located on the side 42 to engage the recess 16. The beveled portion 21 projects radially outwardly from the end edge 26, and has holes 44 for connection (for example by riveting) to the cooking vessel. To assemble the handle assembly 1, the connecting member 3 fits in the connecting portion 6 of the handle 2 along the axis A, such that the end edge 25 rests against the shoulder 10.; given the elasticity of the connecting member 3 and the presence of the inlet 17, therefore the preassembly teeth 37 click into the chair 15 and cooperate and rest against a retaining surface 45 of the chair 15 facing the edge of the chair 15. end 25 and therefore the opposite shoulder 10. The connecting member 3 is thus pre-assembled and firmly secured to the handle 2, by the pre-assembly teeth 37 that engage the chair 15, and also by virtue of the tapered portion of the portion of connection 6 and collar portion 20, but can still be removed. The connecting member 3 is permanently connected to the handle 2 by permanently pressing and deforming the clamping member 38 within the recess 16. The clamping member 38 penetrates the recess 16 and cooperates with and rests against a retaining surface 46 formed in the wall 118 of the recess 16 facing the end edge 25 and therefore the opposite shoulder 10, such that the connecting member 3 is secured axially between the shoulder 10 and the retaining surfaces 45, 46. Given the curved shape of the slot 40a, the end points of the curved slot 40a, of the clamping member 38 exert a thrust on the retaining surface 46 to press the edge end 25 against the shoulder 10 of the handle and thus compensate for any slack. In the variation of Figures 7 and 8, in which details similar or identical to those already described are indicated using the same reference numerals, the side wall 30 only has a slot 40 defining the sector 39 defining the member 38. The sector 39 is therefore joined by the slot 40 by a portion 47 of the end edge 25; the slot 40 is curved along the axis A, with its end edge facing the concavity 26 and the beveled portion 21, and therefore faces a connecting end by which the connecting member 3 is connected to the container kitchen; and the recess 16 is joined by a front wall 18 and to the rear by the shoulder 10. In this case also, when the sector 39 is pressed into the recess 16, the end points of the curved slot 40 of the clamping member 38 exert a thrust on the retaining surface 46 formed in the wall 18 of the recess 16, and thus pushes the portion 47 in such a way that it cooperates with and rests against the shoulder 10.

Clearly, changes can be made to what is described and illustrated herein without, however, departing from the scope of the appended claims.
