Definitions
- the present invention is in the field of hand tools, and it relates to a utensil intended mainly for professional use, such as knife, chopper, sharpener, etc.
- Hand tools comprising a symmetrical functional part extending into a so-called silk part, penetrating inside a handle, the said handle being composed of a rigid material covered with an elastic material for the comfort of the gripping.
- HANDLER Hydrophilic Acid
- Handles of hand tools are more particularly known having these same characteristics, of which the said rigid material is a plastic material such as those described by patents FR 2611567 (GARNACHE), GB 2065537 (HILTI) and US 2871899 (COYLE).
- the said rigid material is a plastic material such as those described by patents FR 2611567 (GARNACHE), GB 2065537 (HILTI) and US 2871899 (COYLE).
- European patent 0176486 (SANELLI), which describes a hand tool whose functional part is asymmetrical.
- the aim of the present invention is to improve the ergonomics of tools, such as a professional knife or a chopper, in particular as regards the comfort of handling and gripping thereof.
- a utensil corresponding to the above-mentioned purpose such as a professional knife, a chopper, of the kind provided on the one hand with a handle, and on the other hand with a functional part rendered integral with the handle by a so-called silk part extending beyond the functional part inside thereof, the said handle being made up on the one hand of rigid material and on the other hand of elastic material for the comfort of gripping, is mainly characterized in that, at least one part of elastic material fills at least one recess formed in the part of rigid material which has continuity over the entire length of the handle.
- the elastic material elastomer
- the elastomer appears rather as a surface layer or coating covering the rigid material, plastic material or metal, which depending on the case appears at the ends or at other points, according to the invention the elastomer extends radially to the heart of the handle and even, according to a more particular arrangement, is in contact with the silk, or even even passes through it by lights.
- the functional part of the utensil being asymmetrical, and the utensil being in a horizontal position with the cutting edge facing downwards, said part made of elastic material extends over most of the lower half of the handle.
- the utensil being produced by injection molding of a rigid plastic material around the silk, the latter comprising lumens for passage of the material and / or cutouts, in order to make the injected material, the material, integral with the silk rigid plastic injected advantageously occupies the anterior (miter), upper and posterior parts of the handle, passing through some of the lumens, and the elastic material, itself injected then, passes through the other lumens.
- the rigid plastic part preferably has a general U-shaped section both in its width and in its length, with a convex curvature of its upper face so that the back of the handle is swollen, and comprises in its median zone along its length a projection bordered on either side by grooves, the said projection enclosing the silk; where it follows that the elastic material, during injection, is housed on the one hand inside the groove resulting from the U-shaped conformation of the rigid plastic part and on the other hand around the projection filling the grooves bordering it.
- the openings for the passage of the material made through the silk being three in number, one of the openings is located in the middle zone of the handle and allows the passage of the rigid plastic material constituting the protrusion through the silk, while the other two lights are located on either side of the first and allow the passage of the elastic material through the silk.
- Figure 1 is a front view of a knife according to the present invention.
- Figure 2 is a partial longitudinal section of the same.
- FIG. 3 is a section of the handle according to AA in FIG. 2.
- FIG. 4 is another section of the handle along BB of FIG. 2.
- a knife is provided on the one hand with a handle 1 and on the other hand with a asymmetrical functional part 2, sharp on one side, back on the other, made integral with the handle 1 by a so-called silk part 3 extending beyond the functional part 2 inside the handle.
- the handle 1 comprises on the one hand a part of elastic material 4 for the comfort of the grip, swollen in its median zone and which extends over the major part of the lower half of the handle 1, and on the other hand a part rigid plastic material 5 which occupies the front (miter), upper and rear parts of the handle 1.
- the plastics 5 and elastic materials 4 being injection molded around the silk 3, the latter comprises three openings 6,6′ and 6 ⁇ for passage of the material and a cutout 7, in order to make it integral with silk 3 the injected material.
- the rigid plastic 5 first injected, is molded in a general U shape along its length, with on the one hand a projection 8 located in its median zone, and on the other hand a convex curvature 10 of its upper face. so that the back of the handle 1 is swollen.
- the rigid plastic material 5 passes through the central lumen 6 and the cutout 7 made in the silk.
- the elastic material injected in the second place passes through the other openings 6 and 6 ⁇ and occupies a major part of the recess formed in the lower zone of the rigid plastic material.
- the rigid plastic part 5 has a general U-shaped section, well characterized at the ends of the handle (see FIG. 4), or even in M if one takes account of the projection 8 (see FIG. 3 ) and comprises in its central zone said projection 8 bordered on either side by grooves 9 and 9 ′ which grips the silk 3.
- the elastic material 4 comes housed on the one hand inside the recess resulting from the U-shaped conformation of the rigid plastic part 5 (see FIG. 4), and on the other hand around the projection 8 (see FIG. 3), filling the grooves 9 and 9 ′ which border them.
