Description

Tin-opener

The present invention relates to a kind of tin-opener.

US4734986, US4782594, US2255641, US4251917, US3094776, US2196182, the US5121546 and the inventor by Patent publish one class tin-openers such as PCT publication number WO90,05108 derivative US5181322, it can prolong the link external opening can at edge, place of can body and can ends.

This tin-opener, its drive wheel and slitter wheel are stuck on the can edge, and drive wheel connects with the rotation of user's operating handle.The rotation of drive wheel is directed at this and takes turns and prolong the can edge and move, and slitter wheel cuts the can outer rim simultaneously, and makes can ends with the other parts of can separately.

The weak point of US518132 and disclosed this class tin-opener of other documents is to guarantee to open and make bottle opener non-slip when blocking the can edge, need apply sizable power between slitter wheel and drive wheel.This means and to be difficult to use this class bottle opener those old men or strength deficiency person such as weak.In US5181322, the inventor proposes drive wheel and metal axle sleeve S. A. knot, this axle sleeve is supported by the tin-opener body, its outside cooperates at the place, two ends of closing on axle sleeve with the inner face of axle sleeve, purpose is to make described axle and those middle parts produce swivel bearing, between the inner face of the outside of axle and axle sleeve, produce a gap,, make when spool rotating to reduce friction with respect to axle sleeve with contacting of axle and axle sleeve.Yet the contriver finds that this design do not deal with problems, and this tin-opener is still not handy.

The objective of the invention is to overcome the deficiencies in the prior art, a kind of manual tin-opener is provided, this bottle opener has the bearing set that is fastened on the drive wheel rotation connection at can edge, described slitter wheel opposite with the slitter wheel of can edge junction and, described drive wheel connects with the drive wheel that centers on the can edge and the manual rotary handle of slitter wheel, and wherein at least one antifriction-bearing box of beam warp rotatably connects with respect to described bearing set.

In other words, the present invention relates to a kind of manually operated tin-opener, the described can of external opening at edge through cutting the lid that links with the can main body, described bottle opener has with the slitter wheel and of can edge junction together and is fastened on the bearing set that the rotation of the drive wheel at can edge, described slitter wheel opposite connects, described drive wheel connects around the drive wheel of can edge walking and the manual rotary handle of slitter wheel with driving, and wherein drive wheel connects with described bearing set rotation through at least one antifriction-bearing box.

Described bearing set comprises a pair of and wears mouthful integrated handle of body that articulates mutually on every side, drive wheel with the axle that passes mouth, with at the bearing of wearing between mouth and the axle, and the mouth of wearing with coupling part that bearing is housed, to body wide to the definite cavity that prolongs connection part and be contained in bearing in this cavity.

The inventor finds to adopt antifriction-bearing box can reduce the difficulty of using tin-opener widely, and known to the most contriver, yet there are no the people in the past bearing is used for kitchen tackle.

Preferred antifriction-bearing box is the needle bearing that its length equals its label at least, maybe can comprise two antifriction-bearing boxs that separately are rotated in the intrinsic axle sleeve.

Below with reference to the nearly step explanation of accompanying drawing technical solution of the present invention, wherein,

Fig. 1 cuts open figure for embodiment of the invention shear constitution side-looking office.

Fig. 2 is the partial enlarged drawing of Fig. 1, the state of visible cutting knife and drive wheel and can interlock.

Fig. 3 a is the drive wheel of Fig. 1 and the cutaway view of axle, and

Fig. 3 b be among Fig. 3 a a-a to view.

Fig. 4 is the cutaway view of Fig. 3 a, and it shows the second embodiment of the present invention.

Fig. 1 is the view of Figure 12 among the US5181322, but this inventive embodiment is shown.

Detailed using method about tin-opener embodiment of the present invention is open in US5181322, and the present invention can be with reference to this patent.

As shown in Figure 1, tin-opener 10 comprises a bearing set that is formed by a pair of handle, and

body part

12 and 14 once-forming respectively forms

handle.Body part

12,14 articulates mutually with crossing sockets 13, and wearing mouth 13 becomes an integral body with body part 12, and deepening is to the corresponding perforate 15 of body 14 parts.

Axle 16 passes mouth 13, one end of described drive wheel 18 forms axle, and this takes turns 18 has analogues such as sawtooth in its outside, when rotation, make it catch can 22(to see Fig. 2 firmly) inner face at edge 20, drive wheel 18 will make tin-opener round can 22 walkings of desiring to open.

At the relative other end of the axle 16 of drive wheel 18, turning handle 19 can manually rotate drive wheel 18.Packing ring 21 is between turning handle 19 and body 12.

Upright turning cylinder 29 links to each other with body part 14, and slitter wheel 30 rotatably connects with turning cylinder 29.Slitter wheel 30 comprises an annular cutting blade 32 and an integral ring-shaped bead 34.The outer cylinder 36 of bead is bigger slightly than the diameter of cutting blade 32, and cylinder 36 can bear against on the upright sidewall 38 of can 22 like this.

Slitter wheel 30 is through adding an end cap 40 rivetings or screwing tight so fix on the axle 29.Be provided with the packing ring 42 that an elastomeric material is made between end cap 40 and the wheel 30, packing ring 41 is contained in the another side of slitter wheel 30.

The axis 42 of mouth 13 is worn in axis 40 skews of axle 16.Like this, a mouthful body part 12 that articulates wears long, 14 when removing handle, and drive wheel 18 is removed slitter wheel 30, thereby drive wheel can be stuck on the edge of the can of desiring to open, on the contrary, when handle is incorporated into a time-out, the user firmly holds with hand, and drive wheel 18 shifts near slitter wheel 30, bead 34 be stuck on the can edge the position as shown in Figure 2, wherein cutoff edge is stuck on the edge of can once folder through slitter wheel 30 and drive wheel 18.Rotation turning handle 19 makes the promptly inner face at can edge of drive wheel 18, therefore, forces described slitter wheel around the can limit, by US5181322(WO90,05108) described in method of operation can cut the can edge.

For make slitter wheel 30 and drive wheel 18 mutually with the can edge keep in touch firmly essential, thereby at axle 16 with wear basic friction of generation between the mouth.The embodiment of the invention shown in Fig. 1 and Fig. 3 a, at

axle

16 and 12 of body parts an antifriction-bearing box 50 is installed, so that a friction-free in fact bearing arrangement to be provided, its centre bearer 50 has an axle sleeve 52(housing) and the needle roller that is full of many axial array of axle sleeve (casing) 52 length, so that friction-free in fact bearing arrangement to be provided.Preferably, the axle phase length of antifriction-bearing box equals its basic width at least, and therefore the width of as many as body 12 parts of the axial length of bearing 50 provides a kind of comprehensive supporting.

As shown in Figure 3,, axle sleeve 52(housing) according to second embodiment of the invention be positioned at axle sleeve 52(casing) first and second antifriction-bearing boxs 56,58 of opposite end cooperate, and be furnished with a sealing member 60 that is contained between the bearing 56,58.

The inventor finds to adopt antifriction-bearing box, can improve the operability of this device widely as needle bearing 50, and to the greatest extent known to the contriver manually cooking utensils yet there are no the people in the past and adopted bearing arrangement.

Needn't adopt further feature to improve, change and replacement some feature of the present invention and disclosed technology, but with spirit of the present invention and scope, the claim below widely explaining.
