Razor blade structure

The present invention relates to a razor blade structure, and particularly relate to a razor handle, a blade assembly can be placed on the handle, when using the cutting edge rust of a blade of blade assembly or each blade always till.Then can take away blade assembly, and replace it with new blade assembly.

" blade assembly " speech used herein, the meaning is meant one, two or more blade, they side by side, parallel, configuration equally spacedly, vertically be installed in the mounting of plastic material.Mounting can, and normally comprise a guard bar and top cover, settle with respect to the cutting edge of each blade, so that provide desired blade orientation or blade geometric figure.

The same blade assembly combination of razor handle, can slip into a recessed bearing, guide rail on the handle by making blade assembly, or by being configured in a pair of claw type pivot member on the handle, this member can be buckled together suddenly by means of a spring one tilt operation mechanism on the handle or separate, with the pivot dimple of co-operate in joint or the discreet knives assembly.One can be around an axle pivoting action that is parallel to this or each blade cut sword with the blade assembly of handle fastening.Some blade assemblies of having sold have plenty of and have rail type engagement groove, have plenty of and have above-mentioned pivot-pawl type engagement dimple.

Such blade is well-known, but is tending towards inconvenient or heavy, when handle is the pivotal mounting type, particularly is a pattern that independent distributor carries that contains six or a plurality of blade assemblies when the blade assembly of replacing blade assembly and use, and is especially true.

According to a razor blade structure provided by the invention, the jockey on a handle and the handle is arranged, this jockey releasably makes handle and blade assembly fastening, to form the work razor.This blade assembly has one or more slashers to be fixed in the blade support consistently, and the distributor that holds a plurality of blade assemblies removably is contained in the above-mentioned handle.

According on the other hand, a razor blade structure provided by the invention has the jockey on a handle and the handle, and this jockey releasably makes handle and blade assembly fastening, to form the work razor.This blade assembly has one or more slashers to be fixed in the blade support consistently.Jockey contains can be right with opposing mobile pivot element master toward each other, so that pay engagement to getting loose with a pivot element on the blade assembly, blade assembly is connected with handle, and then the motion of pivot is around the axle that is parallel to this or each blade cut sword.Also have a distributor that contains a plurality of blade assemblies, in distributor, above-mentioned pivot element master is to being Elastic Meshing.From the pivot element disengaging engagement of blade assembly then is by moving perpendicular to handle the blade assembly length plane.Each blade assembly can be by removing from distributor moving of its length direction.

To at length set forth the present invention now, with reference to the accompanying drawings, only with the example explanation.

Fig. 1 is a side view according to the recommendation form of razor blade structure of the present invention;

Fig. 2, Fig. 3, Fig. 4 are respectively front view, rearview and the bottom views of device shown in Figure 1;

Fig. 5 is the vertical view of distributor;

Fig. 6 is the cutaway view of Fig. 5 along VI-VI line;

Fig. 7-10 is respectively the front view of second embodiment of razor blade structure, rearview and bottom view;

Figure 11 and 12 is respectively the plane and the profilograph of the distributor of razor blade structure second embodiment.

Shown in Fig. 1-6, first embodiment of razor blade structure comprises a razor handle 10, and it has a tubular to hold part 11, holds part 11 via the blade assembly supporting 13 of neck 12 to the handle upper end.The other end of handle is equipped with removable end cap 14.

According to blade assembly and blade assembly supporting 13 forms that are adjacent to blade assembly supporting 13 is shaped.In the embodiment of the Fig. 1-6 that proposes, blade assembly supporting 13 contains a pair of elastic claw 13a,, and is suitable for the corresponding dimple cooperation among the thin slice 15a of being connected on the rear side of fastening mode and a blade assembly 15 with the handle global formation by plastic material.Like this, blade assembly 15 is supported on the handle 10, and this handle is around a pivot motion of the cutting edge that is parallel to this or each blade.

Though 13 forms with the engaged claw in the blade assembly dimple that support also illustrate.If but blade assembly is made of the projection that has the pin shape, then should form pawl 13a with holding these protruding dimples accordingly.

The blade assembly distributor or the box 16 that are shown among Fig. 5 and Fig. 6 contain handle end cap 14, and it is a cylindricality, and a mandrel 16a axially expands.As, mandrel is integral with three radial spoke sheet 16b.Three 16c of compartment that are limited between them hold independent blade assembly respectively, and an end of each compartment is being opened.The radial outer end of each spoke sheet, around it to track of surface bearing, or one or more orbital segment 16d, the track on the opposite of each track or orbital segment and next adjacent spoke sheet or orbital segment acting in conjunction are to clamp a blade assembly 15 between them.

Lost certain or each blade 15b(Fig. 6 behind the sharpness in order to replace described device), at first distributor 16 is pulled out from razor handle with clip, take off end cap 14.Take away the blade assembly of using then, razor is being come perpendicular to the plane of blade assembly length towards the blade assembly motion, the groove 15c on pawl 13a and the new blade assembly afterbody is meshed in the fastening mode up to razor handle.New then blade assembly is drawn out distributor by handle, and blade assembly is pulled through the openend of compartment along its length direction.

The blade assembly that links to each other with razor handle if desired, can be inserted into a space compartment of distributor 16, perhaps as required, it can be taken off.In other razor blade structure, the appropriate location of razor on handle that goes out cash and carry sales usually has a dummy assembly (promptly not having blade).

From known distributor, can understand.Blade assembly is usually by catching the pawl clamping, and this links to each other with the elastic wall of compartment on being pressed in blade assembly.So blade assembly must be pulled out compartment along perpendicular to the blade assembly length direction with after handle is connected.For this reason, pawl type insert supporting must be stuck on the blade assembly at the locked position of pawl at pawl, and in hope when razor handle unloads blade assembly, also must break into two with one's hands with hand.

On the contrary, in the embodiment that the present invention proposes, compartment's one end is an opening, and thus, handle has the elastic claw in aggregates with it, and the rigidity of this elastic claw only needs to satisfy clamps blade assembly, and makes its lengthwise movement.This rigidity need not overcome the resistance that common distributor catches pawl.Handle has been avoided cost, weight and the complexity of common claw handle like this.

In the embodiment of Fig. 7-12, razor handle (110) is rectangular cross section normally, and is to be made of a pawl type blade assembly support (113), and this support has pawl 113a.The distributor 116 of a square-section is housed in the handle, and the configuration of this distributor is as a drawer in the handle.In this case, distributor forms one, for example, the 11c of compartment of four common plane, this compartment lines up two row, and every row has two compartment.And the end cap of this handle has the common plane of square-section.In this case,, move to blade assembly, blade will be connected with handle by handle as above-mentioned first embodiment that relates to.And pawl is flexibly snapped in the pawl groove at blade assembly (15) back side (seeing the blade assembly of Fig. 6).Then, blade assembly overcomes the resistance to sliding of catching pawl (116d) of a vertical wall of compartment.

Each compartment at least at one end is an opening.If desired, preceding two compartment away from top cover 114 can be articulated in latter two compartment, so that unload blade assembly from latter two compartment.

Though the form that the present invention recommends be above narrated about a claw type handle, but can also provide a simple form of this device, this form is that blade assembly is fixed by the method and the handle of rail type supporting, and this rail type props up the groove scope that handle is arranged in blade assembly that bears against.Otherwise can obtain identical result.
