    This invention relates to hand cutting tools for personal use, in particular, a razor blade assembly.
    The aim of the invention is to improve performance.
    FIG. 1 shows a razor, longitudinal section; in fig. 2 - a unit with a working position of the blade platform of the form, a longitudinal section, in FIG. 3 - the same with the non-working position of the blade platform; FIG. 4 shows the blade platform, top view of FIG. 5, the same, front view; in fig. 6 - the same, bottom view; in fig. 7 - frame with cover, longitudinal section; in fig. 8 - the same, rear view; 9 shows a blade platform., I variant; in fig. 10 - knot, type of front; in fig. 11 the same, rear view; in fig. 12 - blade platform, II version; in fig. 13 - unit (II version) with the working position of the blade platform; in fig. 14 - the same, with the non-working position of the blade platform.
    The razor blade assembly contains frame 1 with key 2 and end parts 3 and 4.
    The frame houses a blade platform 5 with a safety ridge 6 made in common with it and a blade 7 fixed on it and a blade 8 mounted stepwise with respect to the blade 7.
    The blade platform 5 is set relative to the frame 1 with the possibility of moving from the working position, in which the cutting edges of the blades 7 and 8 are exposed for shaving j to the non-working position, in which the cutting edges are closed by the cover 2.
    The blade platform 5 and the frame 1 have an interaction between the guide surfaces to ensure movement of the platform, made in the form of two protrusions 9 or two grooves 10 located on the end portions of the frame and platform.
    In accordance with the first embodiment of the razor blade assembly, the frame 1 has a base 115 located under the blade platform 5 with the lid 2 on the side opposite to the safety ridge 6, a window 12 for accommodating a handle 13 that can be connected to the blade body 131360 2
    form and intended to influence the user. The base and the blade platform have interacting with each other 5 protrusion 14 and 15, the radius of curvature of the vapazna 15 being large radii of curvature of BbiCTyna 14 to ensure that the blade platform 5 rolls relative to the frame io
    50 One of the grooves of the 10 end part is made of a fan-shaped form with a straight side 16J in contact with one of the sides of the protrusion 95 that goes into the groove and a junction {base
     17, facing the convex part to
    the protrusion 9 and in contact with its free side. The other groove 10 of the end part is expanding towards the blade platform 5,
    20, one of its sides 18 is in contact with the protrusion 9 interacting with the groove, and the second is 19 in parallel to the right side 16 of the fan groove,
    In accordance with the second embodiment of the razor blade assembly, the protrusions 20 and the grooves 21 on the end portions of the frame 1 and the blade platform j are made with the POSSIBILITY of its moving one relative to the other, with the grooves 2i being rounded and / or mutually inclined to desiccate; blade platforg.-Go; 5 regarding frame 1,
    35 When used; 1H; And with the knot of the brilliant yaz climber, it is executed according to the first variant, with the handle 13, the blade of the platform is rolled by the protrusion i 4 along Bi ia.nvine 1 3 :. exposing cutting hromka
     razor blades: or l ozodod them under krzhzhu,
    This movement is guided by the use of slippery clutches of each mobile axle, its surface 22

    with a fixed guide, a guide surface 23 and a tacky guide surface 24 with a fixed guide surface 25. In this way, a slip between the rolling surfaces is prevented.
    To restore the knot to the shaving position — the position 1 is pressed Flipped up until its gripping portion 26 in the center of the partition snaps into
    55 notch 27 from the center of the rear edge
    clamps 2. Mutually coupled;: surfaces capture, parts 26 and slots 27 are inclined by iodine by an angle ,, when
    which maintains the pressure of the handle 13 upwards and thereby keeps the blade platform assembly 13 in close contact with the front edge of the upper edge 2 lying below. Such tight contact prevents the upper blade 8 from vibrating.
    The razor is assembled by inserting the blade platform 5 into frame 1, before engaging the protrusions 9 with the guide surfaces 10. At the guide edges of the projections 9, the chamfers are removed, therefore the pressure applied by the k platform 5 bends the end walls 3 and 4 outwards and allows Slide the protrusions 9 to slide along the surfaces of the 10 end walls.
    The node in the second embodiment is similar to that described, the difference being that there are no rolling surfaces 14 and 15, as well. sliders in the form of protrusions 20 protruding outwardly from opposite sides of the blade platform 5 interlock in a sliding manner with
    20 of the platform relative to the frame; one of the grooves of the end part is made with a fan-shaped shape with a straight side in contact with one of the sides of the protrusion entering the groove and arcuate
    guiding grooves 21, made in the end walls 3 and 4. These pro-bases facing the convex part can be straight or curvature to the protrusion and in contact with its linear ones and placed under the chosen free side, the other notch - tilted toward each other to obtain any form of rolling movement of the blade platform relative to the frame. The upper and lower surfaces of the protrusions 20 and the upper and lower surfaces of the grooves 21 form guide surfaces equivalent to the rolling surfaces and guides supporting the frame with the lid and the front face of the assembly, made along the first parts and placed in the frame new version. a platform made of
    one safety blade with one blade fixed to it, mounted relative to the frame with a possibility of movement from the working position, in which the cutting edge of the blade is exposed for the shaving part is made expanding towards the blade platform, while one of its sides contacts the protrusion interacting with the groove and the other extends parallel to the straight side of the fan groove. 2. The razor blade unit, a hundred, in an uncompleted position, while in addition, when the knot is run on both the first and second versions, the end wall may be provided with protrusions for engaging with guide surfaces on the blade platform.
     torus, the cutting edge is closed by a cap, invented whereby the blade platform and frame
    have interacting with each other
    1. A razor blade assembly, containing surfaces for providing a frame with a lid and butt-end movement of the platform, are made with blades and a blade platform placed in the frame with a safety ridge made in one frame with it and
    Formula
    In the form of two protrusions and two grooves located on the end parts of the frame and platform, it is necessary so that, in order to improve performance, fixed on it with a single blade,
    relative to the frame with
    possibility of movement from the working stupa and grooves on the end parts of the ramp position, in which the cutting edge and blade platform are made
    the blade is exposed for shaving, in a non-crawling position, in which I am cutting one or the other,

    the rim of the edge is closed by a crinkle, the blade platform and the frame have interacting guide surfaces to ensure the movement of the platform, made in the form of two projections and two grooves located on the end portions of the frame and platform, differing
    the fact that, in order to improve performance, the frame has a base located under the blade platform that forms with a lid with
    side opposite to the safety ridge, window, blade
    the platform and the base have an interlocking protrusion and a trough, with the radius of curvature of the depression of the projectile Radius of curvature of the projection to provide rolling edge
    with respect to the frame, one of the grooves of the end part is made with a fan-shaped shape with a straight side in contact with one of the sides of the protrusion entering the groove and arcuate
    base facing the protrusion to the protrusion and in contact with its free side, the other groove butt-containing frame with the lid and the frontal parts and placed in the frame the blade platform with
    base facing the protrusion to the protrusion and in contact with its free side, the other groove butt-containing frame with the lid and the frontal parts and placed in the frame the blade platform with
    The second part is made expanding towards the blade platform, with one of its sides contacting the protrusion interacting with the groove, and the other extending parallel to the right side of the fan-shaped groove. 2. The razor blade unit, a hundred, in an uneven position in which the cutting edge is closed with a blade and the blade platform and frame
