Abstract
A knife for household and professional uses comprises a handle (3) having a rigid core member (5) and an outer covering (8) of a soft elastomeric material fitted removably over the core member (5) and being retained in place by a pin (11) to be inserted into a seat (12) formed in the core member (5) through apertures (13,14) provided in the outer covering.
Description
- This invention relates to a knife for household and professional uses, of a type which comprises a handle consisting of a rigid core member with an outer covering. As is known, widespread acceptance are currently enjoying knives of the so-called soft handle type, which are utilized not only for professional applications, for which they were originally intended, but also in household environments.
- The handle of such knives usually consists of a core member, made of a rigid synthetic plastic material molded around the knife blade metal tang, and a covering of a soft and pliant elastomeric material molded over the rigid core member.
- While being generally satisfactory especially from the standpoint of their performance, conventional soft-handled knives are deficient from the sanitary standpoint. In fact, crevices and voids tend to form in the areas of attachment of the soft covering material to the rigid core material wherein liquids and organic residue matter are retained which are difficult to remove, even by repeatedly washing the knife; as a result, such residual matter creates, in decomposing, dangerous bacteria niches.
- The problem underlying this invention is to provide a knife of the type outlined above, which has such constructional and performance features as to overcome the drawbacks affecting the prior art as discussed hereinabove.
- This problem is solved, according to the invention, by a knife as indicated being characterized in that said covering fits removably over said core member.
- Advantageously according to the invention, this knife also comprises means of retaining the covering in its fitted position over the core member.
- Further features and the advantages of a knife according to the invention will become apparent from the following detailed description of a preferred embodiment thereof, to be taken by way of illustration and not of limitation in conjunction with the accompanying drawings.
- In the drawings:
- Figure 1 is a fragmentary exploded view in perspective of a knife according to this invention;
- Figure 2 is a part-sectional view of the knife shown in Figure 1;
- Figure 3 is a part-sectional side view of the knife shown in Figure 1; and
- Figure 4 is a sectional view of the inventive knife, taken along the line IV-IV in Figure 3.
- With reference to the drawing figures, the
numeral 1 generally designates a knife for household and professional uses, which comprises a steel blade 2 associated with ahandle 3 as explained hereinafter. - The blade 2 has a plate-like tang 4 formed integrally therewith.
- The
handle 3 comprises acore member 5 of a rigid synthetic plastic material, molded around the tang 4. - Advantageously, two hollowed
portions core member 5, respectively along opposedmajor sides - The
handle 3 further comprises a covering 8 molded from a soft elastomeric material, such as a thermoplastic rubber, and fitted removably over thecore member 5. In accordance with this invention, the covering 8 is composed of a cap-like body wherein anaxial recess 9 is formed which is open at aforward end 8a and configured to receive thecore member 5 in matching shape relationship. - The
knife 1 also comprises ameans 10 of retaining the covering 8 in its fitted position over thecore member 5; this retainer means 10 advantageously consists of apin 11 adapted to fit removably into aseat 12, formed in thecore member 5, by going throughapertures covering 8. - The
pin 11 has ahead 15, slotted as at 16, acylindrical stem 17, and alug 18 projecting transversely from thestem 17, all these parts being a unitary construction. Indicated at 19, moreover, is a portion of saidpin 11 which is integral with thestem 17 at thehead 15 and forms an angular protrusion on thestem 17. - A
bevel 20 is formed on theside 5b of thecore member 5, at afree end 5c of the latter. - The
seat 12 is formed crosswise in thecore member 5, in the proximity of thefree end 5c, extends from theside 5a to thebevel 20, and has a shape matching that of thecylindrical stem 17/angular protrusion 19 combination on thepin 11. Furthermore, thecore member 5 is formed with anopening 21 in communication with theseat 12 to accommodate thelug 18 as thepin 11 is introduced into theseat 12. - It should be also noted that the
pin 11 section lying between thelug 18 and thehead 15 has a greater length than theseat 12, thereby, after thepin 11 is introduced into theseat 12, thelug 18 is left free to turn within thebevel 20. - The circular,
coaxial apertures covering 8, at a location close to to arearward end 8b thereof, respectively at theseat 12 and thebevel 20. More specifically, the diameter of theaperture 13 is the same as that of thehead 15, and the diameter of theaperture 14 is the same as that of thestem 17 of thepin 11. - According to this invention, the
handle 3 is assembled to theknife 1 by fitting the covering 8 over thecore member 5, to then lock it in its fitted position over the core member by inserting thepin 11 through theaperture 13 into theseat 12. - Thereafter, the
pin 11 is turned until, by virtue of itsportion 19, the pin snaps into theseat 12 and is locked therein by itslug 18 locating itself, after being pushed past theseat 12, within thebevel 20, thereby thepin 11 is prevented from slipping out unintentionally. - To remove the covering 8 from the
core member 5 of thehandle 3, the same procedure is followed in the reverse order. - As a result, the knife for household and professional uses, according to this invention, has been provided with a quickly demountable handle which can then be easily and thoroughly washed clean to meet the strictest of sanitary criteria.
- It is important to observe that the hollowed portions in the handle rigid core member and facing toward the soft covering afford improved deformability for the covering, thereby enhancing the resilient effect and soft-contact property of the handle while leaving its strength properties unaffected.
