The seat bottom 16 of seat 14 can be connected to the part of frame assembly 12, in order to control it when folding and/or expansion stroller 10, moves.Seat bottom 16 can bind by two belts 62 or tether the place ahead cross member 34 of frame assembly 12.Back of seat 18 can similarly be connected to the part of frame assembly 12, in order to control it when folding or expansion stroller 10, moves.Back of seat 18 can connect or bind by fabric portions 64 or flap guides section 30.
As more detailed description hereinafter, stroller 10 is deployable be setting as shown in Figure 1 or use in configure, and be foldable to the compact arrangement shown in Fig. 2 to 4.In order to carry out this operation, the user can untie the breech lock 60 on frame side, and it will discharge push rod 20 in order to move with respect to the guiding section 30 on each frame side.In this example, usually show to a certain extent two independent mechanical latches 60.Be understood by those skilled in the art that, can utilize some different types of breech locks, bolt lock structure and release actuator.It is known adopting many strollers of single release actuator between push rod in the middle of handlebar stem.Described actuator can be via through push rod and handle, at the hawser of inner route, activating two breech locks, on each frame side one.This system can be used on disclosed stroller 10.
According to teaching of the present utility model, collapsible stroller 10 and frame assembly 12 can move in the expansion of Fig. 1 is used or between the configuration of collapsed compact of setting configuration and Fig. 2 to 4.Push rod 20 in the folded configuration of Fig. 2 to 4, be movable to substantially or partly with corresponding guiding section 30 side by side, above corresponding guiding section 30, below corresponding guiding section 30 or enter corresponding position of guiding section 30.Foreleg 40 in the folded configuration of Fig. 2 to 4, be movable to substantially or partly with corresponding guiding section 30 side by side, above corresponding guiding section 30, below corresponding guiding section 30 or enter corresponding position of guiding section 30.Push rod 20 in the expansion of Fig. 1 is used, in configuration, also be movable to substantially or partly from the guiding section extend, above the guiding section, below the guiding section or in the outside position of extending of guiding section.Equally, foreleg 40 in the expansion of Fig. 1 is used, in configuration, be movable to substantially or partly from the guiding section extend, below the guiding section, above the guiding section or in the outside position of extending of guiding section.
In disclosed example, each the be generally linear element in push rod 20, guiding section 30 and foreleg 40.Push rod and foreleg can slip into and skid off guiding section 30 with stretch mode when folding and expansion frame assembly 12.When launching, frame side has relatively long length, because push rod 20, guiding section 30 and foreleg 40 can all relative to each other extend.When folding up, frame side has relatively short length.Push rod 20 and foreleg 40 all are collapsed in guiding section 30 in the folded configuration of frame assembly, thereby produce relatively short length.
As shown in Fig. 2 to 4, when frame assembly 12 is folded up, foreleg 40 can be downwards towards bottom fixed track section 56 pivotables and be pivoted on it and/or with its pivotable abreast substantially.Back leg 36 or pillar also can with respect to and with bottom rail 38 abreast and/or with its pivotable forward and backward abreast substantially.In an example, back leg 36 or pillar can be along guiding section 30 and bottom rail 38 location.This can allow bottom rail 38 and guiding section 30 directly to be collapsed to go up each other or be close to each other, thus the compacter folded configuration of generation.By falling forward and downwards, back leg 36 also can allow the bottom rail in folded configuration, keeping relatively short.And when folding up, rear truck 58 can be along bottom fixed track section 56 towards front wheel assembly 42 to front slide and enter bottom fixed track section 56 or within it.This can shorten the length of bottom rail 38 when stroller 10 is folded into folded configuration.
The structure of the frame assembly 12 disclosed can be stroller compact substantially folded configuration is provided, and can produce the relative rectangular shape that occupies less space of easy manipulation and storage.Seat bottom 16 also can be in folded configuration towards and leaning seat chair back 18 and folding up.This can be held in seat 14 in the cube shaped of folded frame assembly set 12.But this seat arrange protecting chair 14 also with regard to seating face when the collection not contaminated or not with dirty Surface Contact.
Referring to Fig. 3 and 4, can see that bottom rail 38, guiding section 30, foreleg 40 and push rod 20 can have hollow inside separately, its length along each assembly defines elongated passage therein.In the example according to teaching of the present utility model, in frame assembly 12 and especially, in these various assembly passages, can adopt push-pull mechanism or system.Described push-pull mechanism or system can be described as folding auxiliary mechanism, and it can be in order to folding assisted and expansion stroller.
Described folding auxiliary mechanism or system can comprise two independent clamp mechanisms or subsystem on each frame side.Each subsystem can comprise a plurality ofly take turns, roller or pulley, it can rotatable mode be arranged in the passage of frame assembly.Each subsystem also can utilize such as the length that is similar to the push-and-pull elements such as metal tape of measuring tape.At least, as long as described push-and-pull element keeps or is constrained in the passage of frame assembly, described push-and-pull element should be enough in fact keep its general shape under tension force and under compression.Described push-and-pull element can be metal strap, and it can cross over its width side direction or cross bending, is similar to and measures band.Described tape subsequently can be easily axially crooked around roller, pulley or wheel.
Fold an example of auxiliary or push-pull mechanism to 8B explanation and description referring to Fig. 5.As shown in Fig. 5 and 6A, the first tape 70 of the first subsystem 72 can have an end 74, and it is fixed near the lower end of push rod 20 via fixture 75.The other end 76 of the first tape 70 can be fixed near the upper end of foreleg 40 via fixture 77.The first tape 70 can go in ring in the first passage 78 in guiding section 30, and can be wound around or go in ring around the first round or the roller 80 of the lower end that can be carried in the guiding section.
The second tape 82 of the second subsystem 84 can have an end 86, and it is fixed to rear truck 58 via fixture 87.The other end 88 of the second tape 82 can be fixed to via fixture 89 lower end of guiding section 30.Fixture 89 can be on guiding section 30 near back leg pivot 52, and can be the pivot axis of the first roller 80.The second tape 82 can go in ring in the second channel 90 in the fixedly section 56 of bottom rail 38, and can in the third channel 92 in foreleg 40, go in ring.The second tape 82 can or be taken turns 94 around second roller and gone in ring or be wound around, second roller or take turns 94 and can in third channel 92, be attached to the upper end of foreleg 40.The second tape 82 also can be wound around around a pair of contiguous roller (that is, the third and fourth roller 96,98), and described a pair of contiguous roller can be provided near the lower end of the forward end of bottom rail 38 and foreleg 40.
Arm or short column 100 are showed in Fig. 5 and 6A, and can extend the axis away from foreleg from the lower end of foreleg 40.Foreleg pivot 50 can be positioned near the free end of arm 100, and therefore can be from length-wise axis skew or the interval of foreleg.This skew can be placed in the foreleg pivot on the rail of bottom, but allows foreleg 40 when folding to be positioned on the top of bottom rail 38.The 3rd roller 96 can be positioned on foreleg pivot 50.The 4th roller 98 can be located with the 3rd roller 96 intervals, and can be positioned in the third channel 92 in foreleg.The second tape 82 can the capable or winding around the third and fourth collars in passage 90,92, in order to do not disturb the fixedly pivoting action between section 56 and foreleg 40 of bottom rail.
Disclose folding auxiliary or push-pull mechanism can aid in fast and easily folding and launch stroller 10.Fig. 6 A and 6B show the layout of the stroller frame 12 in erectting configuration of stroller 10 wherein and the first and second subsystems 72,84 of showing respectively push-and-pull tape mechanism.An only side that hereinafter refers again to frame assembly 12 is described, and opposite side is operation in the same manner in disclosed example.Breech lock 60 can have the actuator handle 102 that is installed to guiding section 30.But general actuator 60 toggle levers, it has the outstanding breech lock finger-type thing 104 of connecting rod 106 from being coupled to actuator handle 102.In latch openings 110 during described breech lock finger-type thing can extend through the hole 108 in guiding section 30 and be placed in push rod 20 in joint or position latching.When breech lock 60 engages, breech lock finger-type thing 104 will prevent that throw-out lever 20 moves with respect to guiding section 30 and therefore frame assembly 12 is held in use or erects in configuration and prevent that framework from folding up.
For fold stroller 10, at first the user must untie breech lock 60 to discharge push rod 20.Can promote or pull actuator handle 102 with pivoted actuator 60, in order to untie breech lock finger-type thing 104 (shown in Fig. 7 A) in the latch openings 110 from push rod 20.When breech lock 60 discharges or unties, push rod 20 freely slides and enters in this example the guiding section towards guiding section 30, as described in Fig. 7 A and 7B.For fold stroller 10, the user can be pushed to push rod 20 in guiding section 30 simply.This can further be pushed to the fixed end of the first tape 70 74 in guiding section 30 together with push rod 20.The first tape will roll around roller 80.Another fixed end 76 of the upper end that is fixed to foreleg 40 of the first tape 70 can cause guiding section 30 and foreleg to slide toward each other simultaneously.In this example, the other end of guiding section 30 slides on foreleg 40.This is because the first tape 70 has regular length between bare terminal 74,76, and owing to around the first roller 80, being wound around and serving as the single-sheaved block subsystem.Therefore when push rod 20 pushes in an end of guiding section, the first tape 70 is can be auxiliary side by side towards the other end with respect to the mobile guiding section 30 of foreleg 40 (because foreleg will for fixing).Therefore, push rod 20 is moved to the guiding section 30 upper end in also in the opposite direction mobile foreleg 40 and by its move into the guiding section lower end in.This enters distance that the guiding section the advances push rod 20 of combination that become the ratio of 2: 1 to shorten to advance with push rod, guides the overall length of section 30 and foreleg 40.This also can arrange that making that push rod 20 is pushed to required load in guiding section 30 reduces half by the single-sheaved block based on the first clamp mechanism or system 72.
A fixed end 86 of the second tape 82 is fixed to rear truck 58 and is wound around around the third and fourth roller 96,98.When during folding, the other end of guiding section 30 moves with respect to foreleg 40, second roller 94 can move with respect to guiding section 30 in the same direction backward, because second roller is carried on the end of foreleg.Yet another fixed end 88 of the second tape 82 is fixed to guiding section 30, is positioned near the other end of guiding section.Therefore, during the second tape 82 can and can be drawn into when the guiding section slides at foreleg 40 around second roller 94 windings and guide section 30 during folding.Therefore one end 86 of the second tape 82 can pull forward bogie truck 58 and trailing wheel assembly set 44 along bottom fixed track section 56 at described when the third and fourth roller 96,98 is wound around.
The upper end of back leg 36 is sentenced the pivotable mode at back leg pivot 52 and is connected to guiding section 30.Back leg pivot 52 is positioned near another lower end of guiding section 30 as shown in Figure 1 and is fixed on guiding section 30.At guiding section 30 with respect to foreleg 40 forward and during down sliding, back leg pivot 52 moves synergistically.When pivot 52 moves, back leg 36 can be towards bottom rail 38 pivotable forward and backward.This will make again to guide section 30 and falls and also make foreleg 40 towards bottom rail 38 pivotable and backward downwards.In the use of Fig. 6 A, 6B, configuration and the part of Fig. 7 A, 7B can have been seen two subsystems 72 of push-and-pull tape mechanism and the change of 84 layout in the change between folded configuration.Also can see the change of the relative positioning of back leg 36, foreleg 40, push rod 20 and guiding section 30.Fig. 8 A, 8B and 9 show the stroller 10 in folded configuration fully.In this configuration, rear truck 58 is dragged forward along bottom rail 38 by the second tape 82 relatively far.This help to shorten the length of bottom rail 38 in folded configuration.The relatively excessive stroke of wheel bogie truck 58 is results of relative large distance between second roller 94 and another fixed end 88 that is connected to second tape 82 of guiding section 30 in folded configuration.
As shown in Fig. 2 to 4,8A, 8B and 9, the parallel to each other and fixedly section 56 can be parallel to substantially bottom rail 38 when folding of foreleg 40, push rod 20 and guiding section 30 is placed.As shown, foreleg 40, push rod 20 and guiding section 30 can be configured to be positioned on the top of bottom rail 38.Yet other layout is possible.Back leg 36 for example can closely be placed with bottom rail 38 and foreleg 40 in this example abreast, and does not extend to combination profile elevation-over or the below of these two assemblies.And other layout is possible.The shape of frame assembly 12 and various assembly and element, size and confirmation can and be confirmed different and meticulousr from this paper displaying and shape, the size described.The frame assembly 12 disclosed and stroller 10 are quite basic mechanisms, and it is only through describing to show function and the layout of push-and-pull or folding auxiliary mechanism or system.Frame assembly 12 can significantly be different from this paper displaying and the example of describing and still work like that by set.
