    A hand knife 20, 120, 220 of the type having a ring-like rotary driven blade 26, useful for cutting meat and the like; a blade housing 24, 124, 224 for a hand knife; and an improved circular blade 26. The blade housing has a generally circular groove 38, 138, 238 in one axial end 40,140,240 of the housing. The groove is as wide at the open end as inwardly to allow the blade to be inserted and removed in an axial direction. The housing receives and fully encloses a ring gear portion 56 of the blade while a cutting portion 60 extends from the groove. A blade retainer 28, 228 secured to the handle acts against a radial flange 62 of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing without removing or loosening the housing from the handle.

    The invention relates to meat industry, namely hand knives for separating meat from bone.
    The purpose of the invention is to improve operational reliability and convenience. oboliv live.
    FIG. 1 shows a knife, a general view; in fig. 2 - the lower part of the knife; in fig. 3 section aa in FIG. in fig. 4 body and blade, increased; in fig. 5 is a partial section in FIG. in fig. .6 - the second version of the knife with a removable body plate, general view; in fig. 7 lower part of the knife according to the second option; Fig.8 section 7; in fig. 9 is a partial section of FIG. in fig. 10 is a partial view of the top of the housing according to the second embodiment; in fig. 11 part knife, enlarged section; in Fig.12 is a variant of the knife, in which the surface of the clamp and the flange in the place of their contact are made beveled.
    A manual knife for separating the bone from the bone contains a handle 1 located therein, the drive gear 2 being able to rotate, an annular body 3 attached to one end of the handle, having an arcuate depression 4 along the perimeter from the inner side, an annular arrangement located in this recess blade 5, mounted rotatably and having a tooth 6 along the top edge, which is arranged to cooperate with gear 2, along the bottom edge is a cutting
    edge 7, as well as the covering blade, before being pulled out of the body towards
    on the side surface there is a flange 8 having a portion 9. bent outwardly. 10, and the height of the recess of the housing 3 is greater than the distance defined in the axial direction between the blade flange and the blade section having a tooth (D is larger than D, FIG. 4). The blade is mounted so that it can interact with one of the sides 11 or 12 of the arcuate recess, the blade body also has an opening 13 for accommodating gear 2.

A new or sharpened blade can then be inserted, with the flange 8 of the blade 1 entering the gap between the lower axial end of the surface 22 of the housing 3 and the free latch 10, which install the blade concentric to the housing, while the tooth is in the recess 4. The sealing is effected with fasteners 17 and 18, to which the clamp is pressed against the surface 22 of the housing. As shown in FIG. 3 and 5, the base of the retainer 10 lies on the cross-section of the collar 16, which extends transversely to the lower surface of the handle 1.
    The latch pivots on the collar 16 towards the core when the fastening elements 17 and

    The handle I, at the location of the retainer 10, has a transverse shoulder 16, and the retainer is provided with fasteners 17 and 18.
    The handle 1 at the location of the body 3 has a concave portion 19 with an emphasis 20 and means 21 for adjusting the axial position of the anvil 20.
    The surfaces of the retainer 10 and the flange 8 at the point of contact are beveled with bevelled (Fig. 12, letter A).
    The area of the ring blade with a cutting edge is made extended downward (figure 4).
    Hand knife works as follows.
    The operator picks up the handle 1, while the ring-shaped blade 5 in the housing 3 is driven by the pinion gear 2 located in the handle. A flexible cable (not shown) driven by an outside engine (n-e ), built into the handle, drives pinion 2.,
    To change the worn-out blades 5, the fasteners 17 and 18 are released, thereby allowing the retainer 10 to be removed from the housing, with the teeth broken on the blade falling out of the recess 4, then the blade

    from the handle 1. A new or sharpened blade can then be inserted, and the flange 8 of the blade 1 is inserted into the gap between the lower axial end of the surface 22 of the housing 3 and the free lock 10, which install the blade concentric to the body, while the tooth is located in the recess 4 The compaction is carried out with fasteners 17 and 18, which press the retainer against the surface 22 of the housing. As shown in FIG. 3 and 5, the base of the latch 10 lies on the cross-section of the collar 16, which extends transversely to the lower surface of the handle 1.
    The latch pivots on the shoulder 16 toward the body when the fastening elements 17 and
    18 put down. This ensures that the ring portions 23 and 24 of the retainer 10 are attracted by the fastening elements 17 and 18 to the annular surface of the housing 3 in order to keep the blade at the proper level inside the recess 4, and also to keep the housing at the handle 1. The surface 22 of the housing serves as a stop to prevent the retainer 10 from pressing a part of the blade with the teeth 6 to the upper edge 25 of the recess, which could delay the rotation of the blade due to friction. The latch has a very small angle with respect to the surface 22, so that the latch portions 23 and 24 initially touch the surface 22 of the housing. When the fasteners are tightened, the latch is slightly deformed, which brings it into contact with the surface | 22 over the entire arcuate contour 28
    Since the latch 10 in thickness | along the arcuate contour 28 has a cylindrical shape, it can be reversible (i.e., the surface 26 can be located at the handle and the housing instead of the surface 27) after the plate is worn out due to rotation of the blade .
    The manner in which the blade 5 is held in the housing 3 is shown in FIG. 2-5. As shown in FIG. 4 and 5, you
    The recess honeycomb exceeds the distance, axially, between the flange
    defined axially between the blade flange and the blade section with a tooth, which creates a gap at the top and side walls of the recess, the peripheral portion of the flange. 8 is flush with the surface 22 of the housing 3, the latch 10 is attached to the handle 1 in such interconnection that opposes this flange 8 and is positioned so that it is flush with the axial end of the body 3 to prevent the blade flange 8 from extending out of the body.

    2. The Knife of the Transducer 1, which is apt to be applied and so that the case has a version for accommodating the gear.
    3. A knife according to claim 1, characterized in that the housing is provided with a removable plate for attachment to the handle, the plate having you
    , stupid, located in the direction of the handle, which is installed with possible contact with the housing.
    Thus, this knife design compensates for the wear of the retainer by turning it with the other side, which creates ease of maintenance. It also has the advantage of preserving the part of the blade that has the tooth by means of a constant axial position inside the housing, which increases reliability in operation.
