Technical field

The invention relates to the field that hand drags the travelling luggage case.More specifically, this invention is pivotally connected to a part of this towing member with this drawbar, and it can be locked a plurality of positions about a towing member with a drawbar.The pivotally connected permission of between this drawbar and this towing member this people can hold this drawbar with the position more comfortable than other situations when a luggage case is pulled on a surface.

Background technology

Various luggage cases generally all are equipped with one or more wheels, thereby make the people can pull chest at whilst on tour.Generally speaking, one can be dragged luggage case also to provide a towing member with arm shape part, and this arm shape part is connected to this part luggage case with a drawbar.The length that this drawbar is connected to the arm shape part of this part luggage case has prevented that when dragging luggage case luggage case contacts with pin with people's leg

Also can use the portable type trailer to drag forever not to be equipped with the luggage case of wheel or towing member.Be fixed on the luggage a general trailer packaged type, provide a wheel and a towing member for dragging this part luggage case.

No matter a towing member is the part of a luggage case, or the part of a trailer, and great majority towing members allow to drag the luggage case selectivity to extend or regain from a quilt drawbar.The ability of extending and regaining this towing member allows this towing member can projection when not pulling this part luggage case.In addition, if this towing member is in retrieving position, then whilst on tour can easier this part luggage be placed on the suitcase of an automobile or an aircraft in the compartment.

Can drag under the situation that is permanently fixed wheel and towing member on the luggage case, one wheeled member of luggage case generally has an extensible towing member, it comprises a pair of parallel expansion link by a drawbar bridging, it can slide in the tubulose holder of independent vertical direction, and this holder tightly is connected in the interior compartment of this part luggage case.We know that also utilizing a single pole to shrink pulls member, and it extends or contraction from a single tube shape holder, and this holder is positioned at the center of this wheel of a luggage case.No matter in which kind of situation, the luggage case with a towing member that is permanently fixed has a holder that is used for drawbar, makes that this drawbar is concordant with the outer surface of this part luggage case when regaining this and pull member.This has prevented this drawbar projection, and has reduced this drawbar is hooked in possibility on other objects, has also improved the aesthetic property of its appearance when not pulling this part luggage case simultaneously.

Perhaps more generally, the luggage case of other types has utilized the extensible towing member of non-contraction, as twisting and with respect to the rod or the bar of this part luggage rotation than trailer.Generally speaking, the clasp that the towing member of this kind twisting has some forms loosens this towing member will pull member be fixed on a side of this part luggage case when not dragging this luggage case and to make at needs, upwards is rotated into a position of extending with pivot to allow this towing member.

No matter be the towing member of what type, extensible towing member provides a device that is used for this towing member is locked in extended position usually.This kind locking device is known by the people in this technology, and it comprises element such as the spring-loaded brake, cam lock, and other interference locks.The release of some locking devices by manual operation one release mechanism device.Other locking devices are to be enough to set out the power of this brake and to unclamp automatically by only applying to this drawbar as many spring-loaded brake apparatus.In addition, some towing members have the locking device that this towing member can be locked in retrieving position.

Finish the assembling of various assemblies of this towing member (100) of this second embodiment by following steps: at first this handle pivot footstalk (142) with this drawbar (104) inserts in this second open-work (154) of this intermediate member (106), makes the 3rd bearing surface (150) engagement of this bearing surface (140) with this intermediate member of this drawbar.Then this handle pivot footstalk nut (164) is inserted in this countersunk (156) of this intermediate member (106) and be screwed into the spiral part (144) of this handle pivot footstalk (142), mesh gently up to the concealed toroidal frame (158) of itself and this intermediate member.Therefore, this handle pivot footstalk nut (164) thus this bearing surface (140) of this drawbar (104) is fixed on the 3rd bearing surface (150) of this intermediate member (106).This handle pivot footstalk nut (164) is preferably one from locking-typed nut, and be preferably and utilize a packing ring (not shown), make in case assemble, this drawbar (104) with this handle pivot footstalk nut can be freely be that pivot rotates with respect to this intermediate member with the axle center of this second open-work (154) of this intermediate member (106), and do not require extra moment of torsion and need not unclamp nut.It is also understood that this handle pivot footstalk (142) of this drawbar (104) and the size of this handle pivot footstalk nut (164) make that this first open-work (152) of this intermediate member (106) can projection.In case by above-mentioned this intermediate member (106) that is assembled to, then use rotator bolt (160) and shoulder nut (162) this intermediate member to be assembled to this arm shape part (102) of this towing member (106) this drawbar (104).At first this first and second bearing surface (146), (148) of this intermediate member (106) are placed between this bearing surface (126) of this end cap (116) of this arm shape part (102), and this first open-work (152) of this intermediate member is alignd with this second open-work (128) of each end cap.Subsequently, with this countersunk (130) of this rotator bolt (160) this end cap of insertion (116), make this second open-work (128) of its each end cap of extend past and this first open-work (152) of this intermediate member of process (106).This rotator bolt nut (162) is inserted in the countersunk (130) of another end cap (116), in wherein this nut being spun on this rotator bolt (160).Identical with this handle pivot footstalk nut (164), this rotator bolt nut (162) is preferably one from locking-typed nut.Along with this rotator bolt nut (162) is tightened on this rotator bolt (160), this rotator bolt head and this rotator bolt nut are engaged on the concealed toroidal frame (132) of this end cap (116), thereby and end cap are moved mutually.The size of this intermediate member (106) makes and only have a slight interference between this bearing surface (126) of first and second bearing surface (146) of this intermediate member, (148) and this end cap (116).Only be to be understood that and on demand rotator bolt nut (162) be spun on the rotator bolt (160), thereby eliminate any gap between this end cap (116) and the lid intermediate member (106), and it is not tightened onto the obvious degree that has stoped this intermediate member and this end cap to do the pivot rotation around the axle of this rotator bolt.

In case assembled this towing member (100) of this second embodiment as described above, can with the diaxon pivot rotation with respect to this arm shape part (102) of this towing member then with this drawbar (104).First this axle is the axle of this rotator bolt (160), and drawbar (104) rotates around this axle with this intermediate member (106) this end cap with respect to this arm shape part (102) of this towing member (100).This first cardinal principle is parallel with this rotating shaft of taking turns of final this part luggage case that has connected this towing member (100).One second this axle is the axle of this handle pivot footstalk (142), and this drawbar (104) can rotate freely with respect to this this intermediate member (106) that pulls member (100) with this grip pivots nut (164).

This multiaxis pivot of this towing member (100) of this second embodiment allow this drawbar (104) towards this arm shape part (102), shown in Figure 10 and 11 with respect to this towing member.In Figure 10, shown the direction of this drawbar (104), it is parallel towards this first that wherein this of this drawbar (104) held part (134).This towards in, this drawbar (104) can be recovered to easily in this part luggage case, its mode is similar to the mode described in this towing member (20) of this first embodiment.As shown in figure 11, this drawbar (104) is around this first and second axle rotation, its mode make with this first plane that intersects vertically in, this second vertical extends and this of this drawbar held part (134) horizontal-extending.This towards in, this of this drawbar (104) held part (134) ideal placed, make the people not crooked wrist just drag this part luggage case, no matter how many angles of inclination of this part luggage case is.

The 3rd embodiment of this towing member comprises this drawbar (200) and connector (202), shown in Figure 12-16.Figure 12 has shown the decomposition assembled view of this drawbar (200) and connector (202) of the 3rd embodiment of this towing member.

Generally speaking, this drawbar (200) of the 3rd embodiment of this towing member comprises one than lower part (204), a higher part (206), and two end cap (208), and one release/release-push (210), it is preferably by polymer material and forms.First identical with this second embodiment with this, this drawbar (202) of the 3rd embodiment is preferably T shape.This drawbar (200) should form this drawbar than lower part (204) this hold half of part (212), and comprise a part pole (214), it is preferably vertically holds part from this and extends along the central shaft of this drawbar.This pole (214) has a constriction, and it forms a cylindrical handle (216) handle and a locking outstanding (218) stops.This locking outstanding (218) has the form of a cylinder substantially, has two cross aisles (220), and this two passage forms its end face (222).This passage (220) is preferably orthogonal quadrature, and intersects at the symmetry axis of this drawbar.For reason discussed below, each passage (220) is preferably has relative wall, thereby it separates mutually slightly from the radial extension of central shaft.One open-work (226) aligns with this central shaft of this drawbar (200), and extend past should be than lower part (204).At last, this drawbar (200) should form several grooves (228) in the part (212) than holding of lower part, with the increase people to the grip of this drawbar and increase the aesthetic property of this drawbar.

The higher part (206) of this drawbar (200) has a semicolumn shell shaped substantially, its formed this drawbar this hold the first half of part (212).One has the center of this higher part (206) of opening (230) extend past of an oval periphery.

This end cap (208) of this drawbar (200) is preferably similar mutually, and is preferably to form and has oval peripheral flat board.Be preferably a pair of countersink head screw hole (232) each end cap of extend past (208).

This release/release-push (210) comprises that one is formed with the oval projections (234) at an external edge (236) around it.The size of this oval projections (234) is littler than the oval opening (230) of the higher part (206) of this drawbar (200), makes this oval projections to pass through from it.Yet the size of the edge of this release/release-push (236) is engaged in making whole release/release-push (210) can't pass this opening greater than the size of the elliptical openings of this higher part (206) of this drawbar (200).The opposite end of this release/release-push (210) comprises a rod (238), and its residue from this button outwards stretches.The rod of this release/release-push (210) is preferably cylindrical.

This connector (202) of the 3rd embodiment of this towing member comprises two similar half connectors (240) and a locking component (242), and it is preferably by polymer material and forms.Half and half connector (240) is preferably and comprises a cavity (244), its substantially by an ectoloph (246) around.In this cavity (244), form a plane (248), and a pair of tubular bar (250) extends vertically on this plane certainly.Half and half connector (240) also is included in the semicolumn journal surface (252) that its ectoloph (246) forms.Place tightly adjacent and that align with this journal surface forms half cylindrical channel (254) recess in cavity, and its radius is slightly larger than this journal surface (252).The size of this journal surface (252) is corresponding with the length and the diameter of this bar (214) cylindrical handle (216) of this drawbar (200).One less semicolumn opening aligns with this journal surface (252), and forms the opposite flank of the ectoloph (246) of half and half connector (240).At last, in this ectoloph (246), form several alignment pins (258) and aligned hole (260).

This locking component (242) of this connector (202) is generally rectangle, and has a pair of opposing parallel surface (262).A pair of oval slit (264) extends to another to the apparent surface through this locking component (242) from a pair of opposing parallel surface (262).This locking component (242) also has relative top (266) and bottom (268) end portion, and partly has a blind cylindrical hole (270) in this bottom end and partly extend to this top end.

We have illustrated the various assemblies of this drawbar (200) and this connector (202) of the 3rd embodiment of this towing member, and the assembling of these assemblies will be discussed now.Assemble this drawbar (200) of the 3rd embodiment of this towing member by following steps: at first with last certainly this this open-work (226) that inserts this drawbar of this rod (238) of this release/release-push (210) than lower part (204).In case do like this, then make this higher part (206) of this drawbar (200) and should meshing of this drawbar than lower part (204).After doing like this, place the opening (230) that this release/release-push (210) makes this higher part (206) of its extend past.In case this of this drawbar (200) higher (206) intermeshes with lower (204) part, then this release/release-push (210) is captured within it, because in fact this edge (236) of this release/release-push is greater than the opening (230) of this higher part of this drawbar.Along with intermesh with lower (204) part these higher (206) of this drawbar (200), this handle (212) that then uses the screw fastener (not shown) that this end cap (208) is connected to subsequently to cover drawbar terminal relatively inserts this screw fastener in the screw hole (232) of this end cap.By behind the above-mentioned connection end cap (208), with this higher (206) of this drawbar (200) be fixed together than lower part (204), then it can't not separated as if not removing end cap.

This connector (202) is assembled to being somebody's turn to do than lower part (204) of this drawbar (200).This finishes by following steps: at first this this handle (216) than the pole (214) of lower part (204) with this drawbar (200) is placed on this journal surface (252) of this half connector (240).This locking component (242) with this connector (202) is placed on its opposing parallel surface (262) subsequently, with the engagement of this plane (248) of this half connector (240), and this blind hole (270) that makes this locking component this drawbar (200) dorsad.In this position, this bar (250) of this half connector (240) part extends in the oval slit (264) of this locking component (242).At last, align with the row hole, school (260) of other half connectors by the alignment pin (258) that makes half and half connector, and this half connector is moved relative to one another intermesh, thereby other this half connector (240) is connected in this assembly up to the outer rim of this half connector (246) respectively.The size and shape of this half connector (240) makes that by above-mentioned when they are intermeshed, this bar (250) of half and half connector meshes in this ellipse slit (264) of this locking component (242) with this bar of other half connectors.This this plane (248) that has prevented this half connector (240) is clipped in this locking component (242) therebetween.Therefore, although this locking component is blocked in the internal volume of this connector (202), this internal volume is created by the cavity of this half connector (240), but this locking component (242) still can change into this pole (214) of this drawbar (200) freely or transform back locking component.This drawbar (200) self, except discussing the locking by following, it can be freely is that pivot is with respect to this connector (202) rotation but can not remove from it, because in fact this locking projection (218) is blocked in the semicolumn passage (254) of this half connector (240) with its central shaft.

After above-mentioned assembling, subsequently this drawbar (200) of the 3rd embodiment and this connector (202) are connected to this distal-most end of this arm shape part (not shown) of this towing member, it is preferably the illustrated type with reference to this first embodiment of this towing member.Similar to this first embodiment of this towing member, this connector (202) preferred dimensions of the 3rd embodiment is to make it can tightly slip into this tubular end of this arm shape part.In doing so, a release component (272) is inserted this connector of creating by this semicolumn opening (256) of this half connector (240) pedestal opening and insert in the blind hole (270) of this locking component (242).When pressing this release component (272), dispose this release component (272) thus making it can activate this arm shape that a locking device (not shown) allows to pull member partly is recovered in the luggage case that it connected.This release component and locking device are known by us in this technical field, and except showing especially, its concrete configuration and details and the present invention are irrelevant.Yet, this drawbar (200) that is to be understood that the 3rd embodiment and the concrete configuration of connector (202) make its can with the release component collaborative work to the spring-loaded type of this drawbar.In case with this connector (202) by above-mentioned this arm shape part that is assembled to this towing member, this tubular bar (250) that then a pair of securing member (not shown) is inserted the distal-most end of this arm shape part and inserted this half connector (140) is being fixed to this connector this arm shape part of this towing member, thus the assembling process of finishing.

In case install fully, then this drawbar (200) selectivity can be locked this connector (202) and this arm shape both direction partly with respect to this towing member of the 3rd embodiment.How to finish these in order to illustrate, Figure 13-16 has shown the drawbar (200) and connector (202) assembly that has removed one and half connectors (240).As its first direction as shown in Figure 13, place this drawbar (200) make its handle (212) towards this plane (248) that is in substantially parallel relationship to this half connector (240).In this position, this locking component (242) that this biasing force of this release component (272) causes this connector (202) moves to this drawbar (200), moves in this locking projection (218) at this drawbar in one of formed passage (220) up to this top end part (266) of this locking component.Because this locking component (242) is placed between the relative wall (224) of this respective channel (220), prevented that by relative wall and the engagement of this locking component this drawbar (200) from rotating freely with respect to this connector (202) around its central shaft with this passage.Yet, the concrete size of this relative wall (224) of each passage (220) make its can than the opposing parallel surface (262) of this locking component (242) separate far away slightly, thereby make that when this drawbar (200) is locked in its first direction this drawbar (200) can rotate around pivot corresponding to this connector (202) through the arc of about 20 degree.

In the time of needs, can be with this drawbar (200) selective lock in its second direction corresponding to this connector (202) and towing member.This can finish by following steps: this oval projections (234) of this release/release-push (210) is pressed on this drawbar (200), and this handle is rotated to its second direction, as shown in figure 16.When according to shown in Figure 14 when pressing this release/release-push (210), this rod (238) of this release/release-push (210) extends in this passage (220) of this locking projection (218) of this pole (214) of this drawbar (200), and with this locking component (242) engagement of this connector (202).This behavior has overcome this release component (272) and has been applied to biasing force on this locking component (242), and force this locking component to leave this drawbar (200), thereby make of respective channel (220) disengaging of the top end (266) of this locking component, as shown in figure 14 from this locking projection (218) of this drawbar.Subsequently, as long as press this release, release-push (210), then this drawbar (200) can rotate freely corresponding to this connector (202).

If necessary, then this drawbar (200) partly can be locked in its second direction corresponding to this arm shape of this connection (202) and this towing member.These need are finished by following easy steps: after this drawbar has rotated to its second direction, unclamp this release/release-push (210) of this drawbar (200).After having discharged this release/release-push (210), the biasing force of this release component (272) forces this towing member (242) to move to this drawbar (200) once more, up to this top end of this towing member partly (266) move in this locking projection (218) of this drawbar in formed other passages (220).Therefore, as shown in figure 16, relative wall (224) and this locking component (242) engagement by with this passage (220) have prevented that again this drawbar (200) from rotating freely around its central shaft corresponding to this connector (202).As discussed above, the size of the relative wall (224) of each passage (220) is to be understood that owing to should be separated a little than the opposing parallel surface (262) of this locking component (242), therefore when locking onto its second direction, this drawbar (200) can rotate around pivot corresponding to this connector (202) through the radian of about 20 degree.Can at any time press release/release-push (210) to allow to adjust corresponding to the residue of this towing member as required the direction of this towing member (200).In addition, importantly be appreciated that press this release/release-push (210) after, the motion of the locking component (242) in this connector (202) causes that this release component (272) removes from this drawbar (200) elasticity.Therefore, by pressing this release/release-push (210), this release component (272) activates this locking device, thereby this arm shape that allows to pull member partly is recovered in the luggage case.

As mentioned above, this drawbar (200) of the 3rd embodiment of this towing member is rotated around pivot in the mode similar to this first embodiment with respect to the residue of this towing member.But, also this drawbar (200) can be locked onto any one of this several directions with respect to this residue of this towing member.The people that this lockout feature allows to drag a luggage case applies a moment of torsion with respect to the axle of this towing member when needed, thereby has avoided the roll that is not intended to this part luggage case when dragging this part luggage case (20) on uneven road surface such as curb.

Similar to first to the 3rd embodiment, the configuration of the 4th embodiment of the present invention makes it be suitable for becoming a part of a luggage case.The 4th embodiment is identical substantially with operation with the profile of this second embodiment, but similar to the 3rd embodiment, and the 4th embodiment has incorporated a locking device and a lock release in its structure into.In the 4th embodiment, the specific design of this locking device allows the user to activate a single button with this handlebar unlocked and allow this handle along two kinematic axis freely-movables that allowed.In the described embodiment of Figure 17-25, this structure especially allows this button that two diverse locations are arranged only, makes when depressing this button, and two kinematic axis all discharge simultaneously.But in another embodiment, the people of this technology of ordinary skill is to be understood that how revising illustrated structure only discharges moving and one second moving to discharge other axles along an axle to allow to depress a concrete button.For example, this button is pressed onto one first presets the degree of depth and will discharge a rotating shaft, be pressed down to darker second rotating shaft that then can discharge.Perhaps, can use a plurality of buttons (for example, each axle is) in another embodiment.

As institute's general view among Figure 18, it has shown the embodiment of a locked hand, and this locked hand allows two axles motions, perhaps this diaxon can be locked onto several and preset of position, or with its release to allow this handle two axle freely-movables.This towing member (700) of the 4th embodiment is preferably and comprises arm shape part (702), one handle (704), and an intermediate member (706).Although show among the figure, make it be connected to one towing member (700) configuration of the 4th embodiment and can drag on the luggage case, it is similar that this of its connected mode and this second embodiment pulls member (102).This arm shape part (702) also is preferably by three barrel (802), (902), forms with (602).This barrel (802), (902), be preferably with (602) have an ellipse, egg type or Fig. 8 cross section, thereby and be preferably and it slipped in another its configuration in one of a contraction mode, and make it be curved in the mode similar to the arm shape part (24) of this arm shape part (102) of this second embodiment or this first embodiment.In explanation during the 4th embodiment, clearly provide how will pull the details that member is connected to this part luggage case, we will be understood that this is identical with design among other embodiment.But, be to be understood that and can especially the 4th embodiment be connected to this part luggage case that its connected mode is similar to this second embodiment, or the additive method known to adopting in this technology.

Figure 19 to 22 provide this system this handle (704) design with and the profile of this first barrel (802) of being connected.Similar to this arm shape part (102) of this second embodiment, outmost first barrel (802) of the 4th embodiment is preferably a pair of bar member, rises and can slip into and skid off by the single holder in this part luggage case.The length of this first barrel (802) has a most proximal end (808), and it slidably is connected with this second barrel (902), and a relative distal-most end (708), and it can be regained or extension from this part luggage case.The a pair of cylindrical member that is spaced apart (710), it can be formed by (but being not limited to) aluminium, steel, plastics or other suitable firm materials, and its most proximal end (808) with this first barrel (802) is connected to the distal-most end (708) of this barrel (802).This cylindrical member (710) of this first barrel (802) with one substantially parallel mode extend laterally along this first barrel (802), this extends best near each other, and is preferably in relative most proximal end (808) and is connected to each other with distal-most end (708).This can finish by following steps: this end cap (811) and this syndeton of being discussed under distal-most end (708) of using this most proximal end (808).Therefore, the effect of two cylindrical members of this of this first barrel (802) (710) and a traditional single pole member are closely similar, and have used two members to replace a monotubular shape member, and this mainly is for purpose attractive in appearance.At last, at least one open-work (712) is preferably by forming corresponding to each cylindrical member (710) that is considered to empty cylindrical member substantially.This first barrel (802) will slip into this second barrel (902) substantially, and it will slip into one the 3rd barrel (602) successively, and it can be the part of the arm shape in this part luggage case (702) holder.In another embodiment, can use any amount of barrel, and can obtain to shrink connection by alternative structure.

This first barrel (802) also comprises a pair of end cap farthest (716), and it can be formed by (but being not limited to) polymer material or metal.Each end cap (716) is roughly ancon, and has a pedestal (718), and the configuration of this pedestal can slide on this distal-most end (718) of one of this cylindrical member (710) it in a socket mode.Can in adjacent to each end cap (716) of this base part (718), form a shoulder (not shown), and its configuration can be made this distal-most edge (708) engagement of itself and each cylindrical member (710), further slide on this cylindrical member to prevent this end cap.Can form one first open-work (722) through this base part (718) of each end cap (716).When this distal-most edge (708) that is inserted into shoulder that this cylindrical member (710) went up and made this end cap (716) and this cylindrical member (710) when this base part with this end cap (716) meshed, this kind base part open-work (722) generally alignd with this open-work (712) of corresponding cylindrical member (710).In an alternate embodiment, this end cap does not need to comprise an open-work (722), but its internal structure can be solid.Can this end cap (716) be invested on the suitable cylindrical member (710) by any method known to the people of this technology of ordinary skill, for example the connection of (but being not limited to) gluing, fastener, welding or other types.

Each end cap (716) also comprises a planar axes bearing surface (726), and its perpendicular quadrature is towards this base part of this end cap.This bearing surface (726) is preferably has a cardinal principle annular peripheral.Can form one second open-work (728) through each bearing surface (726), this bearing surface is preferably and is positioned at this bearing surface (726) central authorities, and perpendicular quadrature.This open-work (728) can be used to hide bullet handle (691) afterwards.In another embodiment, can eliminate this open-work (728), it is solid making end cap (716).Preferable situation is, this second open-work (728) is identical substantially with the diameter of this first open-work (722) if in being included in, but this does not necessarily require.

One axle collar (791) is connected on this bearing surface (726), and this axle collar is roughly annular, and its diameter generally is less than the diameter of this bearing surface (726).Connected a slit ring (751) subsequently on this axle collar (791), it also generally is an annular, and its external diameter generally is less than the diameter of this bearing surface (726) greater than the diameter of this axle collar (791), although can use bigger or less slit ring (751) in alternate embodiment.If there is this second open-work (728), then it can continue through this axle collar and this slit ring (751), makes each slit ring (751) and the axle collar (791) for empty.Although eliminated this second open-work (728), this slit ring (751) will still be generally empty shape, thereby make this ring adjacent to an opening.Comprise at least one slit (753) within each slit ring (751).This slit (753) passes a side of this slit ring (751), radiation along this slit ring (751), thereby will encircle adjacent opening be connected (perhaps only producing an opening) with space outside this slit ring (751) even do not connect fully through this space outerpace in this direction.The width and the degree of depth of each slit (753) are predefined.Select width to make it be equal to or greater than the thickness of this oar (771) (discussing afterwards) in advance.The degree of depth can be any degree of depth, maybe can pass completely through this slit ring, or can be any short degree of depth.But this degree of depth is preferably the object that is enough to the engagement width similar to this slit (753) to fixing a width, and it need not and can twist in this slit.The slit ring (751) of one end cap (716) generally is parallel to this slit ring (751) of other end caps (716), and separates with it.

From Figure 19 as seen, this drawbar (704) of the 4th embodiment of this towing member (700) is preferably by polymer material and/or metal and forms, but also can be formed by any material known to the people of this technology of ordinary skill.This drawbar (704) is generally T shape (although can form branch according to shown in the figure) and comprises and hold part (734), and this is held part and has a relative free terminal (736) and (737) and a pole partly (738).The pole of this drawbar (704) part (738) is preferably holds part (734) by this and integrates and forms, but this is also nonessential.This is held part (734) and is preferably big body hole structure with this pole (738).Cross-section this grip part (734) of this pole part (738) is preferably from its perpendicular quadrature extends.Leaving this at the end of this pole part (738) holds part (734) and forms a bearing surface (740).

Because can connect two and half connectors by any method known to the people who is familiar with this technology, then an intermediate member (706) of this towing member (700) is preferably by a condensate and forms, or can be formed by the parts of any other quantity.This intermediate member (706) is generally T shape structure, and comprises a pair of terminal relatively and first and second annular bearing surface (746), (748) that are separated from each other parallel to each other that are formed at this intermediate member (706).Go up to form one the 3rd annular bearing surface (750) at this intermediate member (706), and make its perpendicular quadrature towards with this first and second bearing surface (746), (748) and disconnected from each other.Intermediate member (706) is preferably the cavity.And then respectively these three bearing surfaces have an open-work on it.This open-work is limited by an edge (846) (848) or (850), the design of wherein being somebody's turn to do (846) (848) or (850) has a diameter and thickness, make that the size of this open-work at edge is corresponding with the diameter of this axle collar, the axle collar that connects this intermediate member around this axle collar oar this interior void simultaneously partly provides a bigger open area.Particularly, this lateral edges (846) is gone up around this axle collar (791) at this end cap (716) with (848), and this top (850) this handle pivot (742) in the empty inside with slit ring (773) and (751) this intermediate member goes up around this axle collar (873), and prevents to remove with the empty inside of (850) side from this intermediate member by edge (846), (848).The people who is familiar with this technology is to be understood that this axle collar/marginal texture provides and rotatablely moves, prevented that simultaneously this mid portion (704) from carrying out linear movement.

Figure 20 and 21 has removed this and has held part (734) and pole part (738), thereby the cut-away view in the zone of Figure 19 is provided.Comprised an opening (739) at an end (737) of holding part (734).Pass this opening (739) and placed the part of PBU pushbutton unit (741).In this preferred embodiment, this PBU pushbutton unit (741) comprises its structure, and this structure has been extended a fixing especially distance by this opening (739).Can cover this part by a pressure button cover (743).And then, a biasing member (745) (being a spring under this situation) is generally arranged, this biasing member is pressed onto this PBU pushbutton unit (741) position of this part of extending by this opening (739).This PBU pushbutton unit (741) will generally have like an antelabium, shoulder or the similar part when biasing device (745) when depressing, and this PBU pushbutton unit partly extends on this opening (739), but can't freely remove by this opening (739).

This drawbar (704) also comprises pad (747) under leader's handle pivot (742) and the leader, and it generally extends with respect to this handle (734) perpendicular quadrature and passes this pole part (738).The preferable tubular structure that is generally of this handle pivot footstalk (742), and have a central bore (842), passing this open-work, pad under this handle (747) can slide.This handle pivot (742) generally also will be about this PBU pushbutton unit (741) free floating, but generally can firmly be connected to this pole part (738).The design of this time pad (747) can allow the user move from the linearity of the conversion of motion of depressing this PBU pushbutton unit for this time pad (747) by the open-work (842) in the handle pivot (742).In described embodiment, this finishes by following steps: design this time pad (747), make it have a moulded head (749) that has an angle in a side.This PBU pushbutton unit will have press down (751) of a corresponding size subsequently, when through this opening (739) this PBU pushbutton unit (741) being pressed onto this PBU pushbutton unit (741) with a biasing device (not shown), this PBU pushbutton unit will locate to have the pressure (751) of a relative size in moulded head (749).Along with the user is depressed into the biasing force of this biasing member (745) with this PBU pushbutton unit (741), this coupling angle slides over each other and forces this time pad (747) along this handle pivot (742) and through the linear distance that moves of this pole part (738) and handle pivot (742).It only is of spendable several dissimilar PBU pushbutton units that the people of this technology of ordinary skill will understand described PBU pushbutton unit (741).In an alternate embodiment, can design this PBU pushbutton unit, thereby (for example with an alternative orientation, the linear direction that this time pad is replaced) promotes this PBU pushbutton unit, and have suitable design alternative, this button motion can be converted to the linear movement of this time pad (747) along this handle pivot (742).The people who is familiar with this technology also will find also can use the button of the 3rd embodiment to finish this motion by substituting.

Preferable situation can prevent maybe that for this time pad (747) and open-work (842) have an other than ring type cross section this time pad (747) is with respect to axle rotation or this open-work (842) in the rotation of this handle pivot around this handle pivot (742).In a preferred embodiment, this time pad (747) is generally polygonal with the cross section of open-work (842), and better cross section is square.

Pedestal at following pad (747) is fixed with an oar (771).Break away from other structures among Figure 22 and shown this oar (771), but in other figure this oar in handle (704).This oar (771) is generally the plane with predetermined thickness, and can be arrowhead form, but the people who is familiar with this technology is to be understood that also and can uses other shapes.This oar (771) can be connected to this time pad (747), its connected mode will make the linearity of this time pad (747) move to cause the linearity of this oar (771) to move, and make this time pad (747) to rotate freely with respect to the axle of this oar (771) around this handle pivot (742).In described embodiment, this can finish by step once: make down pad (747) be the cavity, then an oar pin (890) is connected to an edge of this oar (771).Figure 22 has shown this details of this oar.This oar pin (890) is preferably the structure of column structure or other types, makes this oar pin (890) to rotate freely around the axle of this handle pivot (742) at the empty center of following pad (747).In order to assemble this structure, this oar pin (890) is placed in the cavity of this time pad (747) intracardiac.And then this oar (771) is pressed to this time pad (747), thereby this oar pin (890) is inserted in this time pad (747), as shown in figure 21 as far as possible with a biasing device (not shown).Finish the linear movement of this oar (771) by step once: when replacing this displacement pin (747) with this PBU pushbutton unit (741), this external structure of this time pad (747) promotes the edge and/or the oar pin (890) of this oar (771).

Pedestal in this handle pivot (742), comprised an axle collar (873) with and the slit ring (773) of slit ring (751) design broadly similar.The parallel slot (874) that slit ring (773) generally comprises at least two coplanes and passes through these two coplanes.Each is similar to the thickness of this oar (771) for the thickness of this slit (874), and generally similar to the slit (753) in this slit ring (751).Open-work (842) is with closely similar this axle collar of mode extend through (873) and this slit ring (773), makes this bearing surface that this second open-work (728) can extend past end cap (716), and connects the axle collar (846) or (848) and slit ring (751).

By pressing down or lack mobile oar (771) between two positions of PBU pushbutton unit and at this PBU pushbutton unit (741) with 2 motion lockings or the release of this handle.At this primary importance (shown in Figure 21 A), this oar (771) is placed at least one slit (753) of this slit ring (751) respectively or is placed at least one slit (973) (but being generally two parallel slots) of slit ring (773).At this second place (shown in Figure 21 B), with this oar from this slit linear move and enter this slit ring (751) the space in the opening on the adjacent slit ring (773).This oar (771) is replaced in the empty inside of intermediate member (706), there is no slit (874) and (753).These positions and one " locking " are corresponding with " release " position.

In order better to understand locking and unlocking operation, the simplest is to explain intermediate member (706), handle pivot (742) and end cap (716) correlation in operation.Preferable situation be by the time this intermediate member edge (850) around the rotation of the axle collar (873) of this handle pivot, and make intermediate member allow the bearing surface (973) of handle pivot (742) and bearing surface (740) on the pole part (738) on the bearing surface (750) of this intermediate member (706), to rotate freely.In kind, by being that suitable edge (846) or (848) rotate around the suitable axle collar (791), the bearing surface (726) of end cap (716) also can rotate freely on bearing surface (746) or (748).

Suppose not exist oar (771), the motion that this handle (704) can cross-section two relevant number of degrees, this to this second embodiment in allowed similar.But, in this case, do not use two pins among second embodiment and use an edge (846) and/or (848) to rotate around this axle collar (791) of end cap (716), and making this handle pivot axle collar (873) go up rotation at the edge (850) of this intermediate member (706), interlocking member (706) is sold rotation with pole part (738) around these two.Particularly, by rotating with respect to this intermediate member (706) with this handle pivot (742), this handle (704) can be around the axle rotation of this handle pivot (742).And then, this intermediate member (706) and this handle (704) can around with the perpendicular rotation of this bearing surface (726) of this end cap (716).This moves and about the illustrated kinematic similitude of the second above embodiment, it allows two different (and being generally perpendicular) axle rotations of this winding by hand.Preferable situation is that these are generally similar to the axle with respect to this part luggage of this second embodiment, but this arrangement and nonessential.It is evident that this structure only allows the rotation around those two axles, and because the structure of intermediate member (706), handle (704) or end cap (716), other motions all are prevented from.

When not having oar (771), do not exist and the identical motion of motion when having this oar (771) in the cavity of middle member (706), so it is corresponding to working as the motion that has oar (771) in the unlocked position.In the illustrated embodiment, the user can press the button device (741), it will overcome existing any bias voltage and cause following pad (747) to be removed from this handle (734) linearity successively, the motion of following pad (747) will be pushed this oar (771) open successively from this lever (734), and will move this oar in this slit.In case there is not slit, then this time pad (747) can rotate freely around this oar (771).Be preferably with any method known to the people who is familiar with this technology and prevent that this oar (771) is around identical axle motion, for example another pin can be connected internally on this intermediate member (706), the open-work (891) of process oar (771) prevents its rotation (this and the shown perpendicular quadrature of Figure 20).This oar (771) can rotate freely corresponding to this end cap (716) with combining also of intermediate member (706).

In case this oar (771) is removed from closed position, then this handle (704) can rotate around two axles with respect to this this arm shape part (702) of pulling member.The multiaxis of this towing member (700) of the 4th embodiment allow this handle (704) towards shown in Figure 17 A, 18B and 17C.

A latched position of this slit ring (773) and (751) this oar, thus this handle (734) is locked onto a precalculated position.If this oar (771) is recovered in this handle (734), make in its groove that enters each abuts slot ring (751), then the entering of this groove (because this groove is wide only similar to the thickness of this oar) prevented the axle rotation of this oar between this end cap in fact, and the implementation partial blockage of slit ring (751) motion.And then, because this time pad only can move about this handle (734) is linear, now this handle lock of oar fix on respect to the position of perpendicular of this end cap (716) bearing surface.

Be recovered to by this oar of oar (771) and can make this handle pivot (742) axle obtain similar result in two parallel slots of this slit ring (773).When passing this slit (773) and place, the robust design of this oar (771) will prevent that this handle pivot (742) from rotating with respect to this oar (771).Now, if allow this oar to rotate freely around this handle pivot (742) at this point, then can not lock this handle (704), because this oar (771) can rotate around handle pivot, and this oar (771) can not be around this intermediate member rotation, and this is because there is not connection therebetween, but in preferred embodiment, when oar was in the groove (793) of the slit ring (773) on this handle pivot (742), this oar (771) also was on the slit (753) of slit ring (751) of this end cap (716).Therefore, this slit ring (751) has prevented that this oar (771) is around the rotation of this handle pivot (742) axle, and this slit ring (751) blocked this oar (771) (and then, when being in the unlocked position, the design that keeps oar to rotate in this has also prevented oar motion in this axle when being in latched position).This obstruction has prevented that this time pad (747) and handle pivot (742) are around the rotation of this handle pivot (742) axle.

As discussed above, preferable situation is design this handle pivot (742), it can't be rotated around the following pad (747) on this handle pivot (742) axle, and therefore also can't rotate freely, thereby stop this handle (704) around arbitrary motion by this time pad (747) and handle pivot (742) are fixed together.This is corresponding with latched position, and when this position, this handle (704) can't be in each motion.

Preferable situation is if there is any groove to align with this oar (771), then this oar (771) to be pressed onto its position in groove (973) and (753).This oar (771) attempts getting back to its position in its groove that can enter.Obviously, this slit ring (773) allows the user to press the button device (741) with (751), move this lever (734) gently, discharge the position that this PBU pushbutton unit (741) also moves to this handle (704) needs subsequently then, in this position, one groove is arranged in the ring, suppose slotless between the home position, and groove is in and needs the position.If discharge this locking device (741) when this oar (771) does not align with a grooving, then this oar (771) can't be recovered to the surface of this slit ring (773) and/or (751).In this position, this oar (771) can be on the surface of this ring smoothly moves, and will stop this lever (734) mobile, aligns with series of grooves and is pressed onto in this groove to prevent that it from moving up to this oar (771).

In Figure 20 and 21 embodiment that showed, should be obvious be, because the size of this slit ring (773) and/or (751), for this oar of oar (771) is recovered in a grooving (973) and/or (753), this oar (771) must can also be recovered in one second grooving (973) and/or (753), is recovered in other slit rings because a slit ring oar blocks this oar (771).This represents user or has freedom or two kinematic axis of locking.This way provides some benefits really, but the people who is familiar with this technology should find, in alternate embodiment, can allow this oar (771) to enter in the series of grooves, still gets clogged even enter these series.

Can select this groove (973) and (753) corresponding to pre-selecting location, this handle (704) can be locked onto in the position these positions user.Like this, this handle (704) can be moved to the precalculated position of needs, in this position with this handlebar locked.This is locked as the user and provides according to the freedom that changes this handling position shown in Figure 17 A and the 17B, Figure 17 A has shown how to reach two diverse locations sharing an axle with 17B, and 17C provides two axles to obtain the latched position of adjusting.The user need not to use wrist muscle that this handle (704) is maintained pre-selecting location, because the locking device of the position of this Figure 17 A, 17B and 17C is fixing with this handle (704).

In some embodiment of the 4th embodiment, also need to press this PBU pushbutton unit (741) thus discharging this locking device (741) extends to keep this arm shape part (702).This can finish by comprise supernumerary structure at least one end cap (716).As shown in figure 23, at one end can comprise a bullet handle (691) in the lid, its design can and enter this end cap (716) in this second open-work (728) internal linear slip.This bullet handle (691) can be pressed in this end cap (716), and the user is pressed into this mid portion (716) by pressing the button device (741) with this oar (771).The arrowhead form of oar (771) can be in the relative angle generation effect of this bullet handle (601), and its mode is identical with the mode of action of this PBU pushbutton unit (741) on following pad (747).This bullet handle (601) can be pressed one handle (811) successively then, and it extends through this first barrel (802).Please note Figure 24 and 25, it has shown this most proximal end (808) of this first barrel (802), this handle (811) is extensible and go up the sympathetic lid (605) of effect by next at a key oar (603) successively, and it is recovered to a stretching pin (607) in the hole (609) of this end cap (811) successively.Be preferably and depress this stretching pin (607), thereby make it not replace when this PBU pushbutton unit (741) that this handle (811) Shi Congkong (609) extends and through the cave (809) of second tubular structure (902).When passing this cave (809), this barrel (802) and (902) are fixed on relative to each other extension state, and since stretching pin (607) hindered its relative to each other motion and it can't be regained.

When the user presses this PBU pushbutton unit (741), thereby may discharge the motion of the handle (734) of two pivots, and the lock that is released in arm shape part (702) simultaneously, thereby make it can be folding in an anti-contraction mode.The people who is familiar with this technology it should also be understood that and then can be with the conversion of motion of this assembly discharging extra locking device, as discharges a lock and extend to allow this arm shape part (702).In logic continuity, can press single button with will be with respect to the motion release of any part of the towing member (700) of any other part.Therefore the single button that can finish this towing member (700) discharges.

The people who is familiar with this technology should be appreciated that the 4th embodiment described in Figure 17-25 only is the embodiment with locking device, and it will allow to discharge this handle makes them can be two axles motions, and selectivity discharges extra locking device.Also can use other structures without suitable test.For example, this oar (771) can be other shapes except " arrow ", especially can't be converted into other whens motion when button pressed downwards has only discharged two axially-movables.And then, need not to use an oar and slit ring lock to decide device, but can be with other structures as a locking device, it allows to press this PBU pushbutton unit to discharge the motion of two axles.Further again, as simple declaration, need not to discharge simultaneously the motion of two axles, and in an alternate embodiment, can no matter successively discharge two motions, the user can select to discharge earlier a motion, or discharge two axles simultaneously, maybe can utilize the correlation of other released movement.

Disclosed the present invention, but this not the restriction to all details in conjunction with some preferred embodiment.Can not break away from the correction and the variation of the present invention's spirit and scope, the people of this technology of ordinary skill should be appreciated that other embodiment are also contained in this announcement simultaneously.
