Razor head of the present invention is when shaving, and with the better function that contacts of skin, it is clean to shave, and the people that shaves also feels comfortably cool.
Describe the present invention in detail below by accompanying drawing, in the accompanying drawing:
Fig. 1 and Fig. 2 are respectively the end of the razor headstock and the perspective view of blade assembly;
Fig. 3 is the profile of doing by the hatching among Fig. 1, and expression is in the blade assembly and the cap spare of normal position at rest;
Fig. 4 is corresponding to Fig. 3, the parts when expression is in different relative position;
Fig. 5 illustrates in use, the generalized section the during diverse location of cap spare and blade assembly;
Fig. 6 is the decomposition diagram of the improved razor headstock and blade assembly;
Fig. 7 is the profile of the headstock shown in Figure 6, and it is corresponding with Fig. 5.
Razor head shown in Fig. 1-4 comprises the headstock 1 metal or injection moulding, and it has an elongated bottom 2 and upright end wall 3 on its two relative ends, has only represented an end of the headstock in these figure, the other end and the mirror image relation that becomes.
Headstock supporting 4, two blade assemblies 5 of a cap spare and three pairs of cantilever wire springs 6, its inner (not shown) is fixed on the mid portion of elongated bottom.
Each blade assembly 5 comprise one narrow; blade 7 with sharp knife edges 7A; with the insert supporting device 8 of a shape, on this supporter, be provided with protection part and a leg that hangs from above 12 that 9, one on a platform has crooked skin contact protection curved surface 11 as L type metal stamping sheet.Supporter is along there being a groove 13 in the overwhelming majority of its length, so that form a space between platform 9 and protection part, blade 7 securely is contained on the platform, and its blade 7A stretches out forward in the space in platform the place ahead.
At the end of supporter 8, have lug 14 to upper offset, this lug is connected in its lower section with the upright end portion 6A of spring 6.
Cap spare 4 comprises the supporting member 16 of a tunnel-shaped, and cap moulding 17 is fixed within it.
Cap spare and blade assembly are in their end tightly is stuck in groove on the end wall 3 of the headstock.More specifically, the lug 14 of insert supporting device is embedded in the narrow vertical channel 18, and this groove also is equipped with the vertical ends 6A of corresponding spring 6.On the next door of each groove 18, be a shallow and wide groove 19, its front 21 plays the block effect of the near-end of each leg 12.
Therefore, each blade assembly since its lug 14 be embedded in the groove 18, thereby guide it in the headstock, to move both vertically.Spring 6 gives and being pressed into, therefore, on the normal position, be resting position, blade assembly by the spring rest on its outermost locations, as shown in Figure 3, spring end 6A is directed and is limited in the corresponding groove 18 and moves both vertically, and its upper end is connected with lug 14, and a fulcrum is provided, and the axle that makes blade assembly center on parallel and close each knife-blade rotates.Represent the most clearly that as Fig. 4 this rotational motion is subjected to the restriction of the front 21 of the back of the end of leg 12 and groove 18 and groove 19 respectively.Place the cap spare 4 of blade assembly back by the direction that shaves, be limited and only guide and to move both vertically, promptly be parallel to blade assembly and move accordingly.Cap spare 4 is also shifted onto its outermost locations by its spring 6 separately, as shown in Figure 3.
Shown in Figure 4 is that moving component is in innermost position, and in this position, spring 6 is pressed towards " extreme lower position " of headstock bottom 2.
When using razor, cap spare and blade assembly can be closely differently contoured consistent with the skin in the zone of shaving, this is because they have direction facing to they suffered spring restoring forces, the advantage that can move independently of one another.The independence of these motions can be found out by itself.But apparently, blade assembly also can freely rotate, and the two can closely contact with skin to make each blade assembly keep its blade 7A and the protective surface 11 that contacts skin, thereby has guaranteed it no matter how the skin surface profile changes and still be in optimum state.This is because the rotating shaft of each blade assembly is parallel with the sharp blade of blade, and just in its front.
Fig. 5 is the variation on the overweening contoured skin, and how the position that how to adapt to the fluctuating, particularly blade assembly of skin surface in order to the moving component of explanation razor is regulated automatically and kept contacting of desired and skin.
The transverse movement of blade assembly said it is " vertical " in front, and certainly, this is the specific position of hypothesis razor head.Regardless of the position of razor, the required direction of motion is to traverse the imaginary plane of the skin contact plane that comprises blade and protection part.
Because the protection feature of blade assembly itself, it no longer needs independent guard member usually, still, if having, then can hang with spring and do transverse movement, the mode of similar cap spare.
Certainly, if desired, razor can have a blade assembly, and perhaps three, perhaps more, but two blade assemblies are thought only at present.
Fig. 6 and Fig. 7 illustrate a kind of modified version of the blade assembly and the headstock, and what they were total is same as the previously described embodiments, but some structure has been done improvement, and this will illustrate below.The dash number of improved embodiment increases by 100 than the numbering of the corresponding part of first embodiment.
Blade assembly 105 is actually consistent with first embodiment is described, and just lug 114 is in the identical platform of protection part, need upwards not depart from.Therefore, the rotating shaft of blade assembly " A " is placed in than on the lower position of first embodiment.
The headstock 101 of injection moulding has different structures, and it has the suspension leg 22 of form known, and according to this configuration, the headstock is suitable for detachable, is contained in the upper end of razor handle, and has limited with respect to handle, around the rotational freedom of the longitudinal axis.
There is a upright cylinder 102A on the last plane of bottom 102, it provides a rivet as an integral body of fixing metal spring part, said metal spring comprises the mid portion 106A of a rectangle, spring detent 106 whole with its formation and that longitudinally stretch out is arranged on it, and this spring detent also sticks up the top to the plane of mid portion 106A.
The rear wall of the headstock 101 has a passage, in order to be received in a cap moulding 117 on the fixed position.
In the end wall 103 of the headstock, groove 118 and 119 is complete opening in the above, and separable clip 123 lug 114 by blade assembly is fixed on blade assembly on the knife rest.
The function and the use of blade assembly more than have been described.
