    [0001] The present invention relates to the field of 5 tools mounted on silk and in particular relates to an interchangeable handle tool. In general, a silk-mounted tool includes a handle that can be either integral with an axial hole for the silk, or a split-in-two block where a location for the silk has been carved in each of the parts. Most often, during assembly, the silk and the handle are assembled and glued together. The handle can also be attached to the silk by rivets or screws. However, with these mounting techniques, the robustness and rigidity of the fixing of the tool head on the handle depends on the quality of the interlocking of the silk in the handle and therefore the drilling accuracy 20 of the axial hole or locations for silk. In addition, once the bonding is done, the tool head is assembled to the handle in a non-removable manner, so that the handle is not interchangeable. It is also known to mold the sleeve directly onto the silk. However, with this technique, the handle is also not separable from the tool head. There is therefore a need for a silk-mounted tool having an easily removable and interchangeable handle while allowing the silk to be firmly held. The present invention aims to satisfy this need and relates to a tool mounted on silk, such as a table cover, comprising a functional part having a first end called tip and a second end called heel, a silk part extending from one piece from the heel in the extension of the functional part, and an interchangeable handle removably mounted on the silk part, the handle comprising at least one axial receiving housing of the silk part, the silk part and the or the housing of the handle being provided with corresponding male and female coupling means for the removable locking of the silk part in the housing or housing, characterized in that the silk part consists of two independent tabs spaced one of the other, which tabs have a length substantially equal to the length of the handle making them able to deform temporarily during insertion into the housing or dwellings of the handle to bring the corresponding male and female coupling means to cooperate to block the silk part in the handle. It is emphasized here that the functional part may be a knife blade, but also a fork-tooth part, or a spoon-spoon. The term "independent tabs" means that the free ends of the tabs are not interconnected. Thanks to the corresponding coupling means, the silk part is locked in the handle so as to prevent unintentional separation of the handle and the silk part during handling of the tool, thus ensuring safety. The temporary deformation of the legs, by their length, allows a quick and easy assembly or disassembly of the interchangeable handle.
    [0002] Moreover, the fact that the silk portion occupies substantially the entire length of the handle provides a better balance for handling the tool. Finally, the removable nature of the handle allows to match the tool with handles of various shapes, colors, various materials, etc. according to the wishes and uses of the user of the tool. According to a particular embodiment of the present invention, the tabs extend substantially along the mean longitudinal axis of the functional part, and are received in a single housing substantially in the center of the handle. Alternatively, the tabs extend parallel to the mean longitudinal axis of the functional portion 15 from each end of the heel, the tabs being each received in a lateral housing formed against the wall defining the handle, the two housings being separated the one of the other by a distance substantially equal to the space between the legs. The silk part may be of the non-visible silk or false type, the free end of the handle, opposite the functional part being closed. The silk part may also be of the through-silk type, at least one of the two tabs extending beyond the open free end of the handle. Preferably, the male and female coupling means formed on the lugs and in the handle are at least one bulge and / or recess produced on each lug and at least one complementary recess and / or bulge made in one or more corresponding positions. in the housing or housing, at least in the region of the legs and the handle near the end thereof opposite the functional part.
    [0003] Advantageously, the legs of the silk portion are of the same thickness as the functional portion and have a substantially straight or curved shape. According to a particular embodiment of the present invention, the handle is made in one piece. As a variant, the handle consists of two plates fastened together, in the case where the assembled handle comprises a single central housing, the two plates being fixed to an intermediate part having a recess which constitutes the housing, and in the case where the assembled handle comprises two separate lateral housings, the two plates being fixed to an intermediate piece of shape and dimension complementary to those of the space between the legs of the silk part. Fixing the pads to the intermediate piece may be by rivets, screws or by welding. The handle may be made of any material, such as wood, plastic, glass, horn, etc. and the assembly consisting of the functional part and the silk part may be made of steel, preferably stainless, or a deformable material such as plastic. The functional part may be a knife blade, a fork portion or a spoonful of spoon. To better illustrate the object of the present invention will be described hereinafter, by way of indication and without limitation, several particular embodiments with reference to the accompanying drawing. In this drawing: Figure 1 is a side view in longitudinal section of the blade and the handle of a knife according to a first embodiment of the present invention, the handle having a single axial housing and the legs of the silk through each comprising a bulge complementary to a recess made in the housing; Figure 2 is a side view in longitudinal section of the blade and the handle of a knife according to a second embodiment of the present invention, the handle having a single axial housing and the legs of the hairpiece each comprising a recess complementary of a bulge realized in the housing; Figure 3 is a longitudinal sectional side view of the blade and handle of a knife and in view from below the knife according to a third embodiment of the present invention, the handle having a single axial housing and the legs of the false silk having a curved shape complementary to that of the housing; Figure 4 is a longitudinal sectional side view of the blade and the handle of a knife according to a fourth embodiment of the present invention, the handle having two axial housings and the legs of the silk each having a complementary bulge of a recess made in each housing; Figure 5 is a side view in longitudinal section of the blade and the handle of a knife according to a fifth embodiment of the present invention, the handle having two axial housings and the legs of the silk having a corrugated shape complementary to that of housing; 6 is a longitudinal sectional side view of the blade and the handle of a knife according to a sixth embodiment of the present invention, the handle having an axial housing and the legs of the silk having a complementary curved shape that of housing; and Figure 7 is an exploded side view of a handle consisting of two plates and an intermediate part according to a particular embodiment of the invention. Referring to FIGS. 1 to 6, it can be seen that the silk-mounted tool is a knife 1. It should be noted that although the described embodiments relate to a knife 1, the mounted tool on silk can be any tool, including a fork, a spoon, or the like. The knife 1 comprises a silk part 2 carrying a functional part 3, called blade, and a handle 4 removably mounted on the silk part 2. In the case where the tool is a fork or a spoon, the functional part is said part teeth or spoon, respectively. The functional part or blade 3 shown in Figures 1 to 6 extends along a longitudinal axis and comprises a tip 31 at its free end, a heel 32 at the end opposite the tip 31, a cutting edge 33 for cutting and a blade back 34 opposite the cutting edge 33.
    [0004] The tip 31 is the thinnest part of the blade 3 and the heel 32 is the thickest part thereof. The blade 3 shown is of the raised blade type 5, that is to say that the tip 31 rises higher than the axis of the blade 3, and is substantially in alignment with the blade back 34 substantially rectilinear . However, it should be noted that the blade 3 can be of any shape. The silk part 2 comprises two lugs 21, 22 extending in one piece from the heel 32 of the blade 3 and in the extension thereof. The two tabs 21, 22 are spaced apart from each other along the length of the heel 32 and are connected to each other only by their bead end. The other end of the tabs 21, 22, opposite to the heel 32, is free. Each lug 21, 22 comprises at least one male and / or female coupling means 23, 24, 26, 27 formed thereon. The male coupling means are in the form of a bulge and the female coupling means are in the form of a recess. The handle 4 extends along a longitudinal axis and has a heel end 41, an opposite end 42, an upper edge 43, a lower edge 44 and a side wall. The heel end end 41 is of the same thickness as the heel 32 of the blade 3 and abuts against it. This is however not limiting, and the heel 30 and the heel end 41 of the handle 4 may have different dimensions, without departing from the scope of the present invention.
    [0005] The upper edge 43 of the handle 4 extends in the extension of the blade back 34. The handle 4 comprises one or more axial housings 45, 46 made along the entire length thereof, so as to receive the tabs 21, 22 of the silk portion 2 in the handle 4. Each housing 45, 46 opens on the heel end end 41 of the handle 4. Each housing 45, 46 further comprises one or more male and / or female coupling means 47 , 48 in this one. The coupling means 47, 48 formed in the housing or recesses 45, 46 correspond in position and form to the coupling means 23, 24, 26, 27 arranged on the tabs 21, 22 of the silk part 2, of such so that they come into engagement for the removable locking of the silk part 2 in the handle 4. Referring first to Figures 1 to 3, it can be seen that the silk part 2, according to a mode In particular embodiment of the present invention comprises two lugs 21, 22 extending parallel to the mean longitudinal axis of the blade 3, equidistant from said axis, and spaced apart from the edges In this particular embodiment, the handle 4 comprises a single axial housing 45 made substantially in the center of the latter. The thickness of the single axial housing 45 is therefore substantially equal to the thickness of the two tabs 21, 22 and 30 of the space 25 between said tabs, to allow a play of operation. The length of the axial housing 45 is also equal to the length of the tabs 21, 22.
    [0006] More specifically, the axial housing 45 may extend over the entire length of the handle 4, opening at both the heel end end 41 and the opposite end 42, as shown in Figure 1.
    [0007] In this case, the silk portion 2 extends through the open end 42 of the handle 4 and is said to pass through. Alternatively, the axial housing 45 may extend from the heel end 41 to a region near the free end 42 of the handle 4, as shown in FIGS. 2 and 3. In this case, the silk portion 2 does not extend through the free end 42 of the handle 4 which is closed, and is said not apparent or false. Furthermore, the tabs 21, 22 of the silk part 2 may have any three-dimensional shape. In particular, as shown in FIGS. 1 and 2, the lugs 21, 22 may extend in a plane parallel to the plane of the blade 3. In a variant, as shown in FIG. 3, the lugs 21, 22 may be curved in a plane perpendicular to that of the blade 3 and containing the longitudinal axis of the blade 3. In each case, the single axial housing 45 has a shape complementary to that of the volume defined by the lugs 21, 22 and the space 25 between them. Furthermore, referring to FIGS. 1 and 2, it can be seen that the coupling means 23, 24, 26, 27 made on the legs 21, 22 and in the housing 45 are located in a close region the free end of the legs 21, 22 and the handle 4. More specifically, as shown in Figure 1, the silk portion 2 comprises an upper lug 21 and a lower lug 22, longer than the upper leg 21. The upper leg 21 has a bulge 23 on its edge opposite the lower leg 22, and the lower leg 22 has another bulge 24 smaller on its edge opposite the upper leg 21, the two bulges 23, 24 being located substantially at the level of the free end of the upper leg 21. It is understood that the shapes and dimensions of the corresponding bulges and recesses are given as illustrative and not limiting. In this case, the single axial housing 45 has an axial hole of the same thickness as all the tabs 21, 22 and the space 25 between them in which are hollowed out two recesses 47, 48 which correspond in position, shape and size to the bulges 23, 24 on the upper tabs 21 and lower 22. In addition, the upper tab 21 being shorter than the lower tab 22, only the lower tab 22 passes through the open end 42 of the handle 4 which The opening corresponds to the thickness of the lower leg 22. Alternatively, as shown in FIG. 2, the silk portion 2 comprises an upper leg 21 and a lower leg 22 of the same length. Each lug 21, 22 has a recess 26, 27 near its free end. The recesses 26, 27 are located at the same distance with respect to the free end, on the upper edge of the upper lug 21 and on the lower edge of the lower lug 22. In this case, the single axial housing 45 has 30 an axial hole of the same thickness as all the lugs 21, 22 and the space 25 between them with a narrowing of the hole located at a position corresponding to those of the recesses 26, 27 on the lugs 21, 22.
    [0008] Referring now to FIGS. 4 and 5, it can be seen that the silk part 2, according to another particular embodiment of the present invention, comprises an upper lug 21 whose upper edge extends in the extension of the the back of the blade 34, and a lower leg 22 whose lower edge extends in the extension of the cutting edge 33 of the blade 3. In this particular embodiment, the handle 4 comprises two axial housings 45, 46 which can be made along the entire length thereof, which housings 45, 46 are spaced from each other by a distance corresponding to the space 25 between the legs 21, 22. These housings 45, 46 are therefore delimited by the side wall of the handle 4 and a wall of the solid part 5 internal to the handle 4. The thickness of each housing 45, 46 is substantially equal to the thickness of the lug 21, 22 corresponding to allow a play of operation. In particular, as shown in FIG. 4, the upper and lower tabs 22 of the silk part 2 extend over the entire length of the handle 4 and each have a bulge 23, 24 protruding into the space 25 between the tabs 21, 22. The bulges 23, 24 are located in a region near the free end of the tabs 21, 22 and are opposite one another. They can also, without departing from the scope of the present invention, be offset relative to each other. The handle 4 comprises an upper housing 45 of the same shape and size as the upper tab 21, with a recess 47 corresponding to the bulge 23 of the upper tab 21.
    [0009] The handle 4 also comprises a lower housing 46 of the same shape and size as the lower tab 22, with a recess 48 corresponding to the bulge 24 of the lower tab 22.
    [0010] In particular, as shown in Figure 5, the upper tabs 21 and lower 22 of the silk portion 2 extend over the entire length of the handle 4 and each have a corrugation on their edges opposite.
    [0011] The handle 4 comprises an upper housing 45 of the same shape and size as the upper lug 21, with a lower corrugation corresponding to the corrugation on the upper lug 21. The handle 4 also comprises a lower housing 46 of the same shape and size as the lower leg 22, with an upper corrugation corresponding to the undulation on the lower leg 22. The solid part 5 inside the handle 4 thus comprises upper and lower corrugations.
    [0012] Referring to FIG. 6, it can be seen that the silk part 2 may also comprise two tabs 21, 22 extending from the heel 32, on either side of the longitudinal axis the blade 3, and each having a curved shape with an outward concavity and a concavity in the space between the two tabs 21, 22, thereby defining a substantially oval-shaped gap between tabs. The handle 4 then comprises a single axial housing 45 consisting of two lateral holes connected to one another at the end of the heel end 41 and spaced apart from one another over the remaining length of the handle 4 by a corresponding solid part 5. in position, shape and dimension at the space 25 between the upper and lower tabs 21. Although the handle 4 as shown in FIGS. 1 to 6 is a one-piece handle, this could also be constituted by several pieces joined together. Referring to FIG. 7, it can be seen that the handle 4 may comprise two plates 6, 7 that may be recessed, the edges of which are capable of cooperating with each other 10 to define the outline of the handle 4. The plates may be in any material (wood, plastic, metal, glass ...). In this case, the particular shape of the housings is given by the arrangement of an intermediate piece 8 between the two plates 6, 7. This intermediate piece 8 extends over the length of the handle 4 and comprises recesses and / or bulges 81, 82 corresponding to those on the legs 21, 22. More specifically, the intermediate piece 8 is complementary to the space 25 between the two lugs 21, 22. When mounting the handle 4 consisting of two plates 6, 7 on the silk part 2, the plates 6, 7 and the intermediate part 8 are assembled by means of rivets, screws, or by welding, or even bonding.
    [0013] In the case where the handle 4 is in one piece, the assembly of the handle 4 on the silk part 2 is made simply and quickly, regardless of the number of housings 45, 46 in the handle 4 and the shape and arrangement of the tabs 21, 22.
    [0014] Indeed, it suffices to insert the tabs 21, 22 through the heel end end 41 of the handle 4, and to slide them in the housing or recesses 45, 46 of the handle 4, so as to provoke their temporary deformation. , until the corresponding male and female coupling means 23, 24, 26, 27, 47, 48 cooperate to block the silk portion 2 in the handle 4. During assembly, the handle 4 does not deform and 5 can therefore be made of any material, such as wood, plastic, glass, horn, etc. The blade 3 is generally made of steel, preferably stainless. The silk part 2, which is the part that is deformed during assembly, is in the same material as the functional part (blade in the embodiment shown) but could also be made of another material allowing deformation of the legs during of the assembly.
    [0015] Such an assembly, without bonding or screwing, also makes it possible to easily and quickly separate the handle 4 from the silk part 2, by temporary deformation of the tabs 21, 22. The presence of the male and female coupling means 23, 24, 26, 27, 47, 48, however, avoids an involuntary separation of the handle 4 and the silk part 2 when handling the knife 1 or the like.
