As shown in Figure 2, become the rear portion strut 3a and the 3b of the rear portion cross-braces 11 joint hand barrows of pivot X-shaped formula.This rear portion cross-braces 11 is connected pivotly so that form branch 12 and the branch 13 of X by pin 14 by place in the middle of them and constitutes.Branch 12 and 13 lower end can pivot round pin 15a, 15b, and pin 15a, 15b are connected to rear portion strut 3a and 3b near the lower end of rear portion strut 3a and 3b.Branch 12 and 13 upper end are pivotally connected to the pin 16a, the 16b that are anchored on sleeve 17a, 17b, and sleeve 17a, 17b are slidably mounted on corresponding rear portion strut 3a, the 3b.
Rear portion X-shaped cross-braces can be substituted by the cross-braces (for example comprising the deformable parallelogram assembly) of any other type, make two side direction assemblies to connect, when hand barrow is in expanded position, remain apart and when being in the 3D folding position of hand barrow, they are brought into together simultaneously.
In order to ensure its stability, hand barrow can also comprise the pedestal cross-braces (not shown) between the front and rear strut that is positioned at hand barrow.It for example can be the type of describing in the document EP 0577496.The folding of this pedestal cross-braces advantageously interrelates with the folding of rear portion cross-braces.
Flexibly connect
The present invention in this hand barrow by substitute the rigid connecting rod that uses routinely flexibly connect or pipe link folds and implements to obtain 3D do not make the both sides of hand barrow will be brought into the motion of cross-braces together so that can not force.Thereby these flexibly connect in 2D is folding and break away from, and are promptly inactive, or do not have slack-freely, and mesh in 3D is folding, i.e. activity or slack-free.
Referring again to Fig. 1, it illustrates side direction assembly 1a and comprises the parts of formation by the fastening slide block 18a of the pin 19a of the upper end of anterior strut 2a.Slide block 18a comprises that also rear portion strut 3a can be around the link pin 20a of its pivot.Slide block 18a also have pusher arm 8a can slide pass wherein, with the parallel passage of anterior strut 2a.In the complete expanded position of the hand barrow shown in Fig. 1, the lower end of pusher arm 8a with respect to slide block 18a to lower process.
Side direction pipe link 21a is connected to pin 22a in the top pivotally, and this pin 22a is anchored on the lower end of pusher arm 8a.Near its lower end, side direction pipe link 21a is connected to pin 23a pivotally, and this pin 23a is anchored on the bottom of rear portion strut 3a.Notice that in the example shown, pin 23a is installed in respect on the strut 3a stationary sleeve 24a of rear portion.
Side direction pipe link 21a surpasses its link pin 23a continuously by extension 25a, is provided with link pin 26a in the lower end of extension 25a, and first end of flexible connecting member 27a is connected in link pin 26a.Second end (upper end) that this flexibly connects is fastened to slider tube 17a by pin 28a, and slider tube 17a is fastened to the upper end of the branch 13 of rear portion cross-braces 11.
This flexible connecting member 27a for example can comprise plastic tape, chain, mfg. metal cord, each other two rigid connecting rods of pivotal joint assembly or more generally can when its tensioning, transmit pulling motion but can not transmit any attaching parts of compression movement.Its length is chosen as and makes when its tensioning, and it is similar to its rigid connecting rod in the hand barrow of document EP 0577496 that substitutes.
Be same identical layout in side direction rack component 1b, wherein corresponding flexible connecting member 27b is fastened to slider tube 17b, and slider tube 17b is fastened to the upper end of the branch 12 of rear portion cross-braces 11.
Folding movement
The invention enables whether movable (tensioning) can propose two folding patterns according to flexibly connecting:
-2D is folding, and as shown in Fig. 3 B, it illustrates the hand barrow during folding: flexible connecting member 27a and 27b be inactive, loosen, and slider tube 17a and 17b and therefore rear portion cross-braces 11 be irremovable;
-3D is folding, and as shown in Fig. 3 A, it illustrates the hand barrow during folding: flexible connecting member 27a and 27b are slack-free, and be movable therefore, drive slider tube 17a and 17b, and therefore drive rear portion cross-braces 11, so that two the side direction assembly 1a and the 1b of hand barrow brought into together.
Fig. 4 roughly illustrates the frame of above-mentioned hand barrow from the side.When hand barrow is in expanded position, flexible connecting member 27a tensioning.
2D is folding
Wish to implement as Fig. 5 and 6 respectively from the side and the 2D that roughly illustrates from behind when folding the user, he promotes pusher arm 8a and 8b simply after starting the tripper (not shown) that is provided with for this purpose.Therefore pusher arm 8a is brought into along anterior strut 2a parallel with 2b by slip with 8b.
Therefore these flexible connecting members 27a and 27b loosen in this position shown in Fig. 5 and 6.Thereby it is folding to obtain 2D.If frame is folding under not collapsible slack-free situation, if or to need not maximization compact, this folding pattern is especially fit closely.
3D is folding
On the other hand, when expectation maximization is compact, for example be used for when closet or vehicle are stored, finish by additional operation easily folding so that the 3D that obtains as Fig. 7 and 8 as shown in folds.
For this reason, the user holds the handle 54 (Fig. 6 and 8) that connects two slider tube 17a and 17b.By acting on this handle (it for example can be a plastic tape), slider tube 17a and 17b are directed along corresponding rear portion strut 3a and 3b, thereby drive the folding of cross-braces 11, and therefore two lateral member of hand barrow are brought into together.In this position, flexible connecting member 27a, 27b tensioning once more.
It is folding also to obtain 3D after the expanded position from Fig. 4 has started tripper.For this reason, the tractive force on the handle 54 causes the folding of cross-braces 11, the side direction assembly is brought into together, and tractive force is applied on flexible connecting member 27a and the 27b, and they are tensioning then.The side direction pipe link 21 that is driven by flexible connecting member 27a is guaranteed rear portion strut 3 folding with respect to the anterior strut 2 of each side direction assembly simultaneously.
Launch
Decide as the case may be, after the tripper that is provided with starting for this purpose, obtain to launch by pulling pusher arm 8a and 8b.If hand barrow is folding with the 2D structure, flexible connecting member 27a and 27b loosen.When launching the side direction assembly, they are tensioning little by little, tensioning in their expanded positions at as shown in figs. 1 and 2 hand barrow.
If hand barrow is folding with 3D structure, the drive side that upwards slides of pusher arm 8 is to the motion of pipe link 21, and this guarantees the interval of rear portion strut with respect to anterior strut.In addition, this side direction pipe link 21 keeps flexible connecting member 27a, 27b tensioning, so that their driving sliding block 17 then, so that rear portion cross-braces 11 adopts its open positions, and two side direction assemblies of mobile trolley away from each other.
Can be provided for auxiliary deployed device, such as the pedal that is installed on the cross-braces.
Thereby the present invention proposes a kind of hand barrow that can adopt two kinds of folding patterns (2D is folding and 3D is folding) simply owing to substitute conventional rigid connecting rod and implement to flexibly connect, so that two types folding separately.

For the 2D that implements hand barrow folding, user's release pusher arm 91 positions, and promote them and slide along anterior strut 92 towards their lower end so that cause them with respect to respective front strut 92.By sliding, pusher arm 91 is applying tractive force on corresponding side direction pipe link 921, and this drives folding of the compass that formed by anterior strut 92 and rear portion strut 93.Pusher arm 91 forwardly this on the strut 92 slides and continues, and is brought into toward each other up to the rear portion of each side direction assembly strut 93, anterior strut 92 and pusher arm 91.
As shown in Figure 12, when the side direction assembly is folding, the link 94 that the front end of the crossing member 9121 of pedestal cross-braces 912 connects thereon slides in groove 9211 along corresponding side direction pipe link 921, so that the angle that is formed by the crossing member 9121 of pedestal cross-braces 912 can not change.Side direction assembly folding thereby can not cause that pedestal cross-braces 912 is folding.Distance between two side direction assemblies thereby can not change, thus the 2D that can obtain as shown in Figure 11 is folding.
From this 2D folding position, the tractive force that is applied on the pusher arm 91 by the user causes that each side direction assembly will be unfolded, and make hand barrow to be unfolded.
Folding and the expansion of 3D
The user can also act on the compass 911 of the folding hand barrow of 2D by the handle 954 that the traction that makes progress is arranged on the described compass 911.This tractive force acts on the pipe link that comprises described compass 911 so that together that it is folding by the side direction assembly is brought into.The side direction assembly brought into cause that together pedestal cross-braces 921 is folding, and the front end of the crossing member 9121 of pedestal cross-braces 912 be connected thereon link 94 along respective lateral pipe link 921 in groove 9211 to front slide.
Thereby, the 3D that obtains the hand barrow shown in Figure 13 is folding, and wherein the link 94 that connects thereon of the crossing member 9121 of pedestal cross-braces 912 has and the identical position of expanded position that is in the hand barrow shown in Fig. 9 and 10 with respect to corresponding side direction pipe link 921 as shown in figure 14.
From the expanded position of the hand barrow shown in Fig. 9, can also hand barrow directly be folded into the 3D structure by acting directly on the handle 954, so that after starting tripper, fold compass 911.The folding of this compass 911 brought the side direction assembly together into, thereby causes the folding of pedestal cross-braces 912.As shown in Figure 10, the link 94 of expanded position that is in hand barrow at place, the front portion of side direction pipe link 921 front end near groove 9211.Therefore can not be when compass 911 be folding along side direction pipe link 921 to front slide.This is folding thereby cause that pusher arm 91 slides along anterior strut 92, up to the 3D folding position that arrives the hand barrow as shown in Figure 13 and 14.
From the 3D folding position, be applied to action on tractive force on the pusher arm 91 is applied to adjacent channels 9211 in the expansion action drives on the side direction assembly the link 94 at front portion place by the user.This action has the effect of launching pedestal cross-braces 912, thereby the side direction assembly is separated from each other and launches hand barrow.
Has the embodiment that is applied to the folding slide unit of the type of tying up
General principles of the present invention can be implemented having on most of hand barrow of 3D folding ability of mind, it comprises implements dynamically to connect so that the side direction assembly brought into cause the folding of described side direction assembly together, but the folding of side direction assembly is not must cause the side direction assembly is brought into together.
Especially, therein the end of X-shaped cross-braces can easily well known to a person skilled in the art dynamically enforcement on " tying up hand barrow " along the replacement scheme that second embodiment is shown that the side direction pipe link slides.
The mechanism that is used for the locking folding position
Figure 15 to 29 illustrates advantageously and can implement, is used for the example of mechanism that locking is in the hand barrow frame of folding position on hand barrow according to the present invention.No matter this locking mechanism can make really in 2D or 3D folded structure, the position of hand barrow will be when it be folding locking.
Lock unit
Figure 15 is the decomposition view that constitutes the element of this locking mechanism.This accompanying drawing illustrates the upper end of rear portion strut 81; Rear portion strut hinged member is also referred to as lower element 82, will be secured to the upper end of rear portion strut 81; Anterior strut hinged member is also referred to as upper element 83, will be secured to anterior strut and make pusher arm to slide.Lower element 82 is designed to around pass the opening 821 of lower element and upper element and 831 axis pivots in upper element 83.
Figure 16 to 18 be locking mechanism be at hand barrow under the situation of expanded position respectively from the side, from the front and the view of cross-sectional plane.In this expanded position, mechanism does not have the locking effect.Can see that in Figure 18 lock-down button 84 can slip into the opening 822 that is defined in the lower element 82.Spring tends to keep it to be in the position of the partly projection shown in Figure 18.Memory cell 841 can vertically slip into the opening 842 that is defined in the lock-down button 84 with the direction of slip of lock-down button 84.Spring tends to keep it to be in the position of the partly projection shown in Figure 18.
In the expanded position of hand barrow, the user can not be near the top 844 of lock-down button 84, and it is hidden in wall 832 back of upper element 83.
The lower end 843 of lock-down button 84 can be by the upper end that is pressed in release unit 851, and this is separated lock unit 851 and can slip in the opening that is defined in the lower element 82 on the direction that is limited by rear portion strut 81.Spring tends to keep separating lock unit 851 and is in it at the tip position shown in Figure 18.
Can see that in Figure 16 and 17 at this expanded position of hand barrow, the upper end of removable yoke 86 and rear portion strut 81 that is in the bottom position of groove 811 relatively separates.This position of removable yoke 86 is corresponding to the expanded position of rear portion cross-braces, and wherein expanded position keeps the lateral member of hand barrow to separate each other.
The principle of locking in the 2D folding position
To be locking mechanisms be under the situation of 2D folding position respectively from the side at hand barrow Figure 19 to 21, the view from front and cross-sectional plane.As shown in Figure 21, lock-down button 84 is in the partly position of projection of its opening 822 from be defined in lower element 82 in this position of hand barrow.Because lower element 82 is with respect to the rotation of upper element 83, top 844 no longer is hidden in the back of wall 832, but alternatively near the edge of this wall.In this position, lock-down button 84 therefore locking lower element 82 with respect to the position, angle of upper element 83, and therefore the rear portion strut of locking hand barrow with respect to the position, angle of anterior strut.
As shown in Figure 19 and 20, in this 2D folding position of hand barrow, removable yoke 86 identical position when in groove 811, being in and launching with hand barrow.In fact the rear portion cross-braces of hand barrow is in identical position.
The principle of locking in the 3D folding position
Figure 22 to 25 be locking mechanism be at hand barrow under the situation of 3D position respectively from the side, from the front and the view two cross-sectional planes.As shown in Figure 24, lock-down button 84 in this position of hand barrow, be in the 2D folding position in identical position.Therefore it go back the angle position of the rear portion strut of locking hand barrow with respect to anterior strut.
As shown in Figure 22, in this 3D folding position of hand barrow, removable yoke 86 is in the tip position in the groove 811 near the upper end of rear portion strut 81.This position of removable yoke is brought into the folding position of the rear portion cross-braces of hand barrow together corresponding to side direction assembly wherein.
As shown in Figure 22 to 25, the locking stops 85 that is promoted by spring leaf 852 is by keeping removable yoke 86 to be in this position in groove 811 its slip locking.The 3D folding position of hand barrow is therefore by the locking mechanism locking.
The release of folding position
The button (it is shown as the wall 832 of adjacent upper portions element 83) that the user can form by the top 844 that acts on by lock-down button 84 comes any one folding position of release.By pushing lock-down button 84, the user pushes the position shown in Figure 26 and 27 with it.
In this position, the top 844 of lock-down button 84 is no longer in abutting connection with the wall 832 of upper element 83.Therefore its no longer locking lower element 82 with respect to the position, angle of upper element 83.
In addition, in this position, the upper end (it slips into its opening then downwards) of separating lock unit 851 is pushed in the lower end 843 of lock-down button 84.The lower end of separating lock unit 851 acts on the locking stops 85 then and makes its retraction lower element 82, thus the passage in the release groove 811.If removable yoke 86 has been in it corresponding to the folding tip position of 3D, its position is unlocked so.
Therefore the action that the user is applied on the top 844 of lock-down button 84 makes no matter be 2D or 3D, the hand barrow folding position can both be unlocked.
Should be noted that as shown in Figure 26, just, when pushing lock-down button 84, the described lock-down button of memory cell 841 lockings position 84, itself thus remain in the position that is pressed.The expansion of hand barrow thereby be easily for the user.Between release moving period of hand barrow, the stops 834 of upper element 83 acts on the memory cell 841 as shown in Figure 28 and 29, so that cause the position of its release locking stops 84.
