Abstract

A razors, one of them blade unit are positioned on the knife rest platform and by loam cake and make its location.Loam cake is removable between the open and close two positions, allows when opening to insert or unload blade unit, and blade unit is fixed on the knife rest platform when closing.Blade unit comprises two parallel blades, also is inserted with a pad therebetween, and this pad extends the end of described blade so that handle blade unit.

Description

We have described a razor assembly in original BP (patent No. NO.2166997) specification; comprising at least one blade and a grill-protected that is positioned at blade cutting edge (or each cutting edge) the place ahead, this grill-protected integrally is connected in the bottom of knife rest by dismountable connector.

Test shows, although above-mentioned razor assembly can provide enough cutting edge protections, still has some users to feel to have any problem when razor loading and unloading blade.

Yet provide a kind of razors in the present invention, this device is made up of following part: an interchangeable blade unit, this element comprises a pair of single-blade mouth blade that is fixed in the pad two sides, and an end of pad prolonged an end of blade so that a convenient handle of handling blade unit to be provided; A knife rest comprises blade platform and cover plate, this cover plate can move between the deployed position that an open position that allows the loading and unloading blade and blade are lived by clamping relative to blade platform, and described handle produces strain and bends towards under the blade platform under the effect of cover plate.

By such structure, the blade knife rest of packing into just is easy to realize, the user is as long as pack blade on its position into handle.When closed knife rest, handle is fixed and automatically is in owing to the closure of cover plate not to be influenced on the position of normally shaving.

In the time will taking off blade, cover plate is opened, and this moment, handle then had a kind of tendency of rebounding to its original position at least partially, therefore can utilize handle to take off blade from knife rest easily.

Except needs, blade unit is packaged so that transport and preserve at first, and each unit all can open and the major part of exposing its blade unit that links to each other with handle it rapidly with enough light protection packaging structure.

Utilization method is for example done an explanation to the optimum implementation of razors of the present invention in conjunction with the accompanying drawings below.

Fig. 1 is the perspective view of a blade unit;

Fig. 2 is the decomposition diagram of blade unit and packing thereof;

Fig. 3 is that blade unit is on its position and the perspective view of razor when being in open mode;

Fig. 4 is the decomposition diagram that explanation is loaded on blade unit razor blade structure;

Fig. 5 is the razor perspective view that installs blade and be in closed dormant state.

Blade unit shown in Figure 1 comprises and a pair ofly permanently is fixed on pad 3 two sides and tandem single dege blade 1,2, and this blade can be by metal or plastic material press forming easily.As shown in the figure, at left end, pad just in time extends beyond the end of blade and has a recess 4 to help the razor location.At the other end, obtain a size and be enough to the handle 6 that pinches with thumb and forefinger easily thereby pad extends beyond blade.Also have a through hole 7 on this handle, explain its purposes back again.8 in hole is in order to locate in packing assembly.

The packing of blade unit comprises a dish 11 among Fig. 2, this dish available as aluminium alloy extruded shaping or the shaping of thermoplastic synthetic resin's vacuum injection, its shape is made one in order to place the concavity 12 of blade unit, upright kick 13 is in order in the hole 7 and 8 that is positioned blade unit, protuberance 14 that is arranged in concavity 12 1 sidewalls in order to recess 4 location of blade unit and one at the narrow groove 15 of the blade oral region that coils in order to the enhanced package dish.Whole packing is finished by metal or plastics thin foil 16, thin foil 16 then covered fully depression and with the bonding depression of sealing of dish, but in the time will using blade unit, this thin foil can be easily be torn from dish.

Shaver comprises a nigger 21 that is connected with the bottom integrated of blade platform 22, one security bar 23 that casts out of one is with it then arranged on the blade platform, the junction surface 24 that is positioned at security bar two ends forms the block of blade cutting edge, the back of blade unit is then fixed by elasticity post 26, one end of platform has a rectangular block 27, and the other end then has an elastic claw 28.

Cover plate 29 is connected in an end of platform by the hinges 31 with the platform one, and the downside of lid has among the inclined-plane 32(figure of two protrusions can only see one of them) in order to when lid is closed, to engage with spring stack 26.

For the new blade unit of on the shaver of opening, packing into, the user need tear thin foil 16 off, with pinching handle 6 and packaging tray respectively with thumb and forefinger on the other hand, pull down the other end of packaging tray then and it is folded down, thus, outside the major part of blade unit just is exposed to, at this moment can be placed on the blade platform, recess 4 is engagement around block, 7 in hole is enclosed within on the elastic claw 28, the user can put down handle 6 now, and cover plate 29 closed it is in the close position, final stage in this closing course, inclined-plane 32 engage with spring stack 26 its back of pushing down blade unit are forward engaged with junction surface 24 until the two ends of blade the place ahead cutting edge.

At last, the free end of cover plate can fasten with elastic claw 28, and cover plate and blade unit are clamped, and the end of cover plate equally also forces handle 6 to fold to below the platform downwards, does not shave thereby can not hinder.

When the cutting edge of blade unit is too blunt can not the time spent, the user can open razor and pinch handle 6 so that old blade unit is unloaded.

Claims

1, a kind of razors is made up of following part: an interchangeable blade unit, this element comprise a pair of single-blade mouth blade that is fixed in the pad two sides, and an end of pad prolonged an end of blade so that a convenient handle of handling blade unit to be provided; A knife rest comprises blade platform and cover plate, this cover plate can move between the deployed position that an open position that allows the loading and unloading blade and blade are lived by clamping relative to blade platform, and described handle is by the pressure generation elastic displacement of cover plate and bend towards under the blade platform.

2, according to the device of claim 1, it is characterized in that: a through hole is arranged on the handle, and the remainder before and after the handle through hole constitutes a zone that has weakened, fashionable under cover plate, in this location handle remainder just bending downwards that has weakened.

3, according to the device of claim 2, it is characterized in that: when being contained in blade unit on the platform, the hole on the described handle just is enclosed within on the protuberance of knife rest.

4, according to the device of claim 3, it is characterized in that: described protuberance is made of an elastic claw that can produce displacement, is used for being interlocked with it on the closing position of cover plate.
