Abstract
A driving mechanism for causing relative movement of one member with respect to another member in which the members are each rotatable about an axis, one of the members having at least a portion thereof shaped in the general form of an epicycloid whilst the other has a portion shaped in the general form of a hypocycloid which said portions are interengageable with one another so that movement of one member causes movement of the other member.
Description
The present invention relates to a kind of driving mechanism that makes an element with respect to another element motion, wherein each element can be separately around a rotation.
In this driving mechanism according to the present invention, one of them element has at least a part to make to be roughly epicycloid shape, then some makes and is roughly hypocycloid shape another element, and these two parts can be interosculated, thereby makes the motion of an element can cause the motion of another element.
Preferably the shape of these two parts is made an epicycloid around a hypocycloidal motion.
This hypocycloid part can be ungulate (parabolic hyppocrcpian) shape of parabola or other non-linear shape.
In a preferred structure, the element with epicycloid shape part is driven by the element with hypocycloid shape part.
Term " epicycloid " and " hypocycloid " are here just used by its general meaning, and the curvilinear path of element of the present invention is not strictly corresponding to the described curve of these terms.
The position of the axis of each element motion can change.For example, when the hypocycloid element drives parabola epicycloid element, hypocycloid can make hypocycloidal the end points relative bigger or less movement locus that draws according to the position of its axis.Similarly, by the position that changes epicycloidal axis also can make hypocycloidal move into non-linear.By driving epicycloid or hypocycloid, can produce a level or the opposing vertical motion.The mutual alignment of the axis by changing two kinds of cycloids, or change hypocycloid or epicycloidal shape, the effective exercise of each end points is changed.
System of the present invention can be applicable to multiple bolt, latch mechanism, and gear mechanism or driving mechanism particularly require the occasion of close tolerance.As previously mentioned, two kinds of cycloids can be driven.
A kind of application of the present invention is to be incorporated in the trigger mechanism of rifle.
In this trigger mechanism, can comprise a trigger gear and a swing hook device.At this moment trigger gear comprises the element of a band hypocycloid part, and the swing hook device comprises the element of a band epicycloid part.
This trigger mechanism can also comprise a locking device, locking device and not motion of trigger mechanism when setting up a kind of device with the assurance shooting in this case possibly.
This moment, locking device can be combined with an element that is suitable for being engaged in trigger mechanism and locking device, promptly made a sharp-pointed bump on parts, and it engages with breach on being made in another parts.In a preferred construction, sharp-pointed projection can be made on the locking mechanism, and breach then is made on the trigger.
Also comprise a kind of rifle within the scope of the invention, it includes an aforesaid driving mechanism, particularly an aforesaid trigger mechanism.
The present invention is for European patent specification 0,280, and the rifle of No. 685 description is particularly useful.The general action of rifle of the present invention is as described in this specification, but the action of its trigger mechanism is then described different fully with this specification, is described in the mode that exemplifies below in conjunction with accompanying drawing.
Should be appreciated that following described trigger mechanism and motion thereof are a kind of concrete mode that driving mechanism of the present invention is implemented.
In the accompanying drawing:
Fig. 1 is a total figure who includes the rifle of driving mechanism of the present invention;
Fig. 2 is the part enlarged view of firing lock; And
Fig. 3 is the part enlarged view of trigger mechanism.
Firing lock mainly comprises the trigger 10 of forming one of two element and the swing hook 20 of forming another element.Trigger 10 can be around pin 11 swings, and pin 11 is formed an axle, and this is by near the hole 12 trigger 10 upper ends.Trigger 10 has the finger grips 13 of a shaping in its underpart.Trigger has one to form hypocycloidal projection 14 on pivot pin 11, and this projection is suitable for incorporation into and forms epicycloidal groove 15 on swing hook 20, and this part below will more detailed description.Trigger 10 also has a hole 16 at its rear portion, a trigger spring 17 is admitted in this hole, and the other end of this spring is contained in the groove 18 of the element 21 of position on trigger retaining ring 22.
Be positioned at element 21 upper ends another groove 23 be the percussion spring 25 an end, the other end of this spring then is positioned at slide block 27, oblique angle 28 is made on the top of this slide block, engages with the lower end of swing hook 20 afterbodys 29.
Usually send out spring by bullet holds it in position above it to a sear 30.
Thereby also be provided with the stroke that an adjusting screw can be regulated sear fully in the percussion spring, sear is by the afterbody operation of swing hook 20.
The swing hook device proper can be around pin 31 swings of forming it in hole 32.It is included in the lock plunger 33 and the tang in its back-end 28 of its front end.The projection 14 of trigger is done as shown in Figure 3 breach 34 at its front end.This breach is suitable for engaging with sharp protrusion portion 35 on the swing hook 20.Lock plunger and trigger did not produce motion when this can guarantee to shoot.
The pivot running of the shape of projection 14 and groove 15 and swing hook and trigger is corresponding to the cooperation of two relative cycloids.
In this case, trigger plays hypocycloidal effect and along lateral movement in the epicycloid of swing hook groove.
When the parabola hypocycloid is driven when swaying, the epicycloidal motion that coincides mutually with hypocycloid is according to the position of hypocycloid axle point, makes hypocycloidal end points make relative and bigger or less motion.
By changing the position of epicycloid pivoting point, hypocycloidal motion can become linearity or nonlinear.This point is suitable for when changing the position of hypocycloid axle point too.
By position or their mutual alignment or change hypocycloid or the epicycloidal shape that changes every kind of cycloid axle point, all can change the effective exercise of each end points.
Example and 0,280, No. 685 disclosed rifles of European patent of said mechanism are specifically contrasted, as can be seen, represented different fully of sear of the present invention and swing hook and trigger and this patent.The sear of this patent is a simple centering block, and its be difficult for to be made, and centering block and safe cage knob is cooperated be difficult for and can not lock slowly.
As can be seen, originally the mechanism that was called H shape centering block device plays sear and body of a gun lock simultaneously, and new structure as described herein improves body of a gun lock and enter body of a gun combination by cylinder, meanwhile, the afterbody of body of a gun lock moves round about, this makes the sear pin that waiting to pull the trigger on the cam and breaking away from of striker is housed from it, thereby the spring that cam and striker are contained in the striker cam chamber drives and moves forward.
This structure guarantees that gun barrel is locked at by the gun barrel locking bolt on gun barrel cover and the gun rack body before thereby sear allows the striker cam to move to hit bullet percussion bullet with striker.This structure also allows to be equipped with an adjusting screw in sear, thereby allows fully to regulate the stroke of the sear pin that is subjected to the operation of centering block afterbody.This can make the susceptibility of firing action and trigger traction be regulated conversely again.As can be seen from the figure, it is incorporated in the similar groove on the sear, it is not moved thereby pin the sear that stops the striker cam to do any motion.
Wait to send out or uncocked position no matter gun are in filling, bumper bar can place safety position.
Therefore but this device can not pulled the trigger and still is in operating state, goes out clearly from rifle and allows this mechanism that bullet is ejected and do not have the danger of unexpected percussion with the method that pump is inhaled this device fiery bullet of checkmating with regard to allowing quickly and easily like this.
Therefore,, also can be used for multiple bolt as previously described though driving mechanism of the present invention is described in conjunction with gun especially, latch mechanism, gear mechanism or driving mechanism etc. particularly requires the occasion of close tolerance.
