Abstract

A lateral-cutting can opener has a body (1) with a handle (2). A cutter (5) is mounted with the body (1) and is rotational about a first axis (7). A traction wheel (11) is positioned on a shaft (8) rotational about a second axis (10) perpendicular to the first axis (7). The shaft (8) is moveable in a direction lateral to the second axis between an inoperative position for receiving a rim (24) of a can (4) between the traction wheel (11) and cutter (5), and an operative position for engaging a rim (24) of a can (4) between the traction wheel (11) and cutter (5).

Description

Lateral-cutting can opener

Technical field

The present invention relates to manual exercisable can opener, the particularly can opener of side direction type of cut.

Background technology

It is for many years known to operate can opener by hand, and can rough classification be three kinds: first type has cutter blade, and described cutter blade directly is cut into the roof of jar; Second type has cutter blade, and described cutter blade is cut in the sidewall of the jar under the limit; And the third type has cutter blade, described cutter blade partly cut to have circumferential wall and by with the edge contraction of wall and end together to form the limit in the limit of the jar of the end of combination.

The second and the 3rd type can be called the side direction type of cut together, described side direction type of cut be used on the edge of jar or under the end that is used to remove jar.Applicant's early stage patent GB2334939 and GB 2341378 (with cooresponding US Patent 6,058,613) have illustrated that a kind of can opener, described can opener are this side direction type of cut.

Representative type side direction type of cut can opener comprises: the first and second elongated operating units, the described first and second elongated operating units are connected to each other pivotly.Each operating unit has handle portion.An operating unit has rotatable traction wheel, and described traction wheel rotor ground is relative with its handle, and additional operating components has cutter blade, and described cutter blade is relative with its handle pivotly.(inoperative) position and wherein mobile between traction wheel and cutter blade and work (operative) position that the limit of jar cooperates of not working at the edge that handle motion is relative to each other held traction wheel and cutter blade jar betwixt.In the operating process of can opener, two handles must be securely held in together in a hand, and operating handle rotates (to move a jar limit between cutter and traction wheel) with an other hand simultaneously.

Two problems of above-mentioned can opener are that the optimum position that is used for that handle is kept together often is not the position that is used to use the most comfortable of opener, and it presses together handle suitably to cooperate jar limit relatively more difficult between cutter and traction wheel with enough power in the process of the operation of operation can opener to the people who has than the weak compactness grip.

The specific embodiment

In the accompanying drawings, described the can opener of side direction type of cut of the present invention, be used for cutting to and have circumferential wall and by the limit of wall and end being folded limit with the jar of the end that forms the limit.Can opener has the main body 1 of shaping at one end to form handle 2.The end of the main body 1 relative with handle 2 has the surface of the end that is used to cooperate the jar 4 that will be opened.Adjacent surface 3 is the rotary cutters 5 with axle 6, and axle 6 is installed with main body 1 and is used for around cutter shaft 7 rotations.

Adjacent cutter 5 is the S. A.s 8 within the curved slot 9 that is placed in the main body 1.Described axle 8 be around perpendicular to cutter shaft 7 second, working shaft 10 is rotatable.Being traction wheel 11 on an end of axle 8, is turning handle 12 on the other end of axle 8, is used for manual S. A. 8 and traction wheel 11.Described axle 8 is being used to hold jars 4 limit 24 with in the inoperative position that is opened between traction wheel 11 and the cutter 5 be used within the groove 9 on the lateral of the working shaft 10 between the control position of mating edge 24 between traction wheel 11 and the cutter 5 removable.The inoperative position is illustrated in Fig. 1,3 and 5.Control position is illustrated in Fig. 2,4,6 and 7.

Traction wheel 11 is provided with frusto-conical surface 20, is used for when axle 8 and traction wheel 11 are in the position of work 5 pairs of jar limits of relative cutter 24 firmly.Frusto-conical surface 20 by annular knurl in the process of opening, to clamp a jar limit 24.

Torsion spring 16 is arranged on fixed leg 17 and is used to be biased between the axle 8 of out-of-run position.

Cam 13 be placed between main body 1 and the rotary handle 12 the axle 8 on.Cam 13 has eccentric peripheral surface 14, and described eccentric peripheral surface 14 has the step 15 that radially extends.Second fixed leg 18 is set for operation of cam 13.

Use rotary handle 12, the user be used to open jars 4 first, on the operative orientation or relative, can not S. A. 8 and traction wheel 11 on the operative orientation.Operative orientation is indicated with arrow 19 in Fig. 3-7.In Fig. 3,4 and 7 of first side that has shown can opener, operative orientation is a C.C.W., and in Fig. 5,6 of second side that has shown can opener, operative orientation is a clws.When axle 8 rotated on operative orientation, cam face 14 was relative to causing axle 8 fixed legs that move towards control position within groove 9 18 to move.

Fixed leg 18 is settled at a certain distance from the control position of axle 8, and cam 18 can not be finished the rotations of whole 360 degree like this, and this turns back to it not active configuration and allow axle 8 to get back to the inoperative position.Those of ordinary skill is appreciated that cam 13 does not have spin locking to arrive axle 8, but with axle 8 frictional fit, like this axle 8 rotation translating cam 13 allows simultaneously axle 8 cam 13 move through its rotate limit fully after continuation rotate.

The surface 3 of main body 1 has protruding oval feature, when it is positioned on jars 4 the end at can opener, is placed within the border of jars 4 circumferential wall 23 assisting limit 24 is placed between traction wheel 11 and the cutter 5.

As shown in Figure 1, handle 2 extends along handle center's line 22, and described handle center line 22 has the use location that is basically perpendicular to jars 4 end and is positioned within the border of jars 4 circumferential wall 23.Like this, handle 2 extends substantially vertically from the end of jar 4.When jar 4 by positioned vertical on chair or running surface (not shown) the time, can opener can remain in the opening operation process in nature, the comfortable position, user's elbow bends, wrist become straight.Because the line of centers 22 of handle 2 is positioned in downwards within the border of circumferential wall 23, pressure can be applied on the can opener and need not overturn jars 4.

In aforesaid explanation, with reference to having the integral body or the parts of known equivalents, if illustrate that separately this will comprise in the present invention.

Although preferred embodiments of the present invention have been disclosed for illustrative, those of ordinary skill are appreciated that and can make amendment to the present invention under the situation that does not deviate from spirit of the present invention and essence, its scope is by claims and be equal to and limit.
