That is, release parts 41 and be supported by elongated hole 91a guiding, along the long side direction energy of the principal part 37 of handle 36 Enough slide relative to principal part 37 and supporting parts 91.
As shown in Fig. 4, Fig. 7 and Fig. 8, releasing parts 41, in the principal part 37 of handle 36, have It is configured at main part (the releasing parts main part) 41a of the supporting elongated hole 91a of supporting parts 91 and along baby The width of youngster's car 10 is from protuberance (releasing parts protuberance, prominent pin) prominent for main part 41a 41b.As shown in Figure 7 and Figure 8, supporting parts 91 and main part 41a between be provided with such as by The main push part 49 that compression spring etc. are constituted.Utilize this main push part 49, parts 41 edge will be released The principal part 37 of handle 36 downward, i.e. direction away from main operating parts 50 pushes.
Through the first elongated hole 37a formed at principal part 37 of protuberance 41b, and extend outside handle 36. First elongated hole 37a is along the moving direction of protuberance 41b, i.e. along the long side direction extension of principal part 37.Such as figure Shown in 4, protuberance 41b can from below with the first connecting rod parts 26 being arranged at stroller main body 11 On the catch 31 of locking component 30 abut.If additionally, folding operation mechanism 40 is operated and is released Parts 41 slide upward along principal part 37, then protuberance 41b abuts with catch 31 from below, lock part Part 30 slides upward along first connecting rod parts 26.If locking component 30 is moved upward, then solve Engaging except locking component 30 with third connecting rod parts 34, it is possible to the folding carrying out stroller main body 11 is moved Make.In the example i.e., here illustrated, it should the position pushed by main push part 49 is to limit baby The restriction site releasing parts 41 of the jackknife action of vehicle main body 11.On the other hand, overcome and promote mainly splenium The position that the active force of part 49 is moved upward along principal part 37, is the folding that can carry out stroller main body 11 The releasing position releasing parts 41 of folded action.
It follows that the transfer unit 43 for folding operation mechanism 40 illustrates.In example illustrated In, locking component 30 be respectively arranged at left and right first connecting rod parts 26, release parts 41 also with a pair Locking component 30 is respectively set at the principal part 37 of the left and right of handle 36 accordingly.Therefore, transfer unit 43 also are arranged in correspondence with being a pair with a pair locking component 30.Additionally, each transfer unit 43 is being arranged at Extend between main operating parts 50 and the releasing parts 41 being arranged at principal part 37 of shell 95.I.e., respectively Transfer unit 43 is being connected with shell 95 and respectively with the cylindrical portion constituting handle 36 together with shell 95 Extend in part.
But, as it is shown in figure 1, the second operation limiting mechanism 60 is only arranged at the principal part 37 in left side, not It is arranged at the principal part 37 on right side.Therefore, in the example in the figures, the structure of transfer unit 43 is second Operation side set by limiting mechanism 60 is different from the side set by the second operation limiting mechanism 60.
Specifically, as shown in Fig. 5～Figure 11, the biography of side set by the second operation limiting mechanism 60 Pass the transfer unit 43 (transfer unit on the right side of the accompanying drawing in Fig. 5 and Fig. 6) in unit 43, i.e. left side Have: be connected to the first connection member 45 of main operating parts 50, be connected to release the second of parts 41 Connection member 46, link the first connection member 45 and the second connection member 46 holding release parts 44. First connection member 45 and the second connection member 46 can pass through the known list of metal wire (steel wire) etc. Unit is constituted.As shown in Fig. 5～Fig. 8, the first connection member 45 has: two ends are connected to rotation section 50b And keep the first thread-like member 45a being made up of soft line etc. releasing parts 44；By the first wire Parts 45a is the first cartridge 45b of through insertion in the way of can sliding.First cartridge 45b Two ends be positioned at rotation section 50b and keeping releasing the position near parts 44 and be fixed on handle 36. Second connection member 46 has: two ends be connected to keep release parts 44 and release parts 41 by soft The second thread-like member 46a that soft line etc. are constituted；By the second thread-like member 46a in the way of can sliding Second cartridge 45b of through insertion.The two ends of the second cartridge 46b are being in holding releasing portion Handle 36 is fixed in the position of the vicinity of part 44 and releasing parts 41.
On the other hand, the transfer unit 43 of the second operation limiting mechanism 60 side, i.e. right side it are not provided with Transfer unit 43 (transfer unit in the left side of the accompanying drawing in Fig. 5 and Fig. 6) has at main operating parts The connection member 47 extended between 50 and releasing parts 41.In the example in the figures, connection member 47 Have: two ends are connected to rotation section 50b and release the wire portion being made up of soft line etc. of parts 41 Part 47a and by thread-like member 47a cartridge 47b of through insertion in the way of can sliding.Tubular The two ends of parts 47b are being in rotation section 50b and are releasing the position near parts 41 and be fixed in handle Hands 36.
As shown in figs.5 and 6, the main operating parts that thread-like member 45a, one end of 47a are fixed The rotation section 50b of 50 has discoideus foreign steamer Guo.In the periphery by the discoideus rotation section 50b constituted Face is formed can the guiding groove 52 of winding wire-like parts 45a, 47a.If additionally, operation controls bar Portion 50a makes rotation section 50b turn to the master shown in Fig. 6 from the position of the main operating parts 50 shown in Fig. 5 The position of functional unit 50, then outside thread-like member 45a, 47a are drawn out to from cartridge 45b, 47b In shell 95, and it is wound in the guiding groove 52 of rotation section 50b.
Now, at the transfer unit 43 (transfer unit in the left side of the accompanying drawing in Fig. 5 and Fig. 6) on right side, By the relative movement relative to cartridge 47b of thread-like member 47a, make releasing parts 41 overcome and promote mainly Splenium part 49 moves to releasing position from restriction site.Transfer unit 43 (Fig. 5 and Fig. 6 in left side In the transfer unit on right side of accompanying drawing), by the first thread-like member 45a relative to the first cartridge The relative movement of 45b, makes the second thread-like member 46a from the second cartridge via keeping releasing parts 44 46b is drawn out to the first connection member 45 side.As a result, by the second thread-like member 46a relative to second The relative movement of shape parts 46b, makes releasing parts 41 overcome main push part 49 from restriction site (figure The position of 7) mobile to releasing position (position of Fig. 8).
That is, according to folding operation mechanism 40, by operation main operating parts 50, a pair releasing parts can be made 41 move to releasing position from restriction site respectively.Therefore, a pair is made by operation main operating parts 50 Locking component 30 moves, and releases the engaging of each locking component 30 and the third connecting rod parts 34 of corresponding side, Stroller main body 11 can be formed as folding state.On the other hand, at main operating parts 50 not By under the state of external force, by the active force from main push part 49, make releasing parts 41 from solution Except position is moved to restriction site.It is accompanied by this, the third connecting rod portion of each locking component 30 and corresponding side Part 34 engages, and the jackknife action of stroller main body 11 is limited.Additionally, about keeping releasing parts 44, Will be described further below together with the second operation limiting mechanism 60.
It follows that illustrate for the first operation limiting mechanism 55.As it has been described above, the first operation limits Mechanism 55 has the first restriction cancellation functional unit 56, and this first restriction cancellation functional unit is by being grasped Work can be from the first lock position (figure limiting the operation using main operating parts 50 for releasing parts 41 The position of 5) mobile to the of the operation that can carry out using main operating parts 50 for releasing parts 41 One unlatched position (position of Fig. 6).
As shown in figs.5 and 6, the first restriction cancellation functional unit 56 is configured at folding operation mechanism The vicinity of the main operating parts 50 of 40.Therefore, the first restriction cancellation functional unit 56 is in the first locking position Put, directly contact with main operating parts 50, the action of the first restriction cancellation functional unit 56 will be limited. That is, it is main that the first operation limiting mechanism 55 and the main operating parts 50 of folding operation mechanism 40 block incompatible restriction The action of functional unit 50, it is possible to limit the operation using main operating parts 50 for releasing parts 41.
As shown in figs.5 and 6, the first restriction cancellation functional unit 56 is identical with main operating parts 50 It is configured in shell 95.As shown in figs.5 and 6, it is formed with to limit with first in shell 95 and solves The guiding groove 97 of division operation parts 56 engaging.The first directed groove of restriction cancellation functional unit 56 97 draws Lead, and be supported on shell 95 in the way of being merely able to slide along constant direction.First restriction cancellation operation Parts 56 have the operation protuberance 56a in the second opening 95b extending into shell 95.Via this behaviour Make protuberance 56a, can operate from the outside of shell 95 to the first restriction cancellation functional unit 56.
As shown in figs.5 and 6, the first restriction cancellation functional unit 56 is formed as the parts of tabular. It is provided with at the first restriction cancellation functional unit 56 and extends from the main part of tabular to the inner side of shell 95 Operation limit holding section (engaging protuberance) 57.This operation limit holding section 57 can be formed at master Notch (operation limiting groove) 51 engaging of the rotation section 50b of functional unit 50.
As shown in figs.5 and 6, arrange between shell 95 and the first restriction cancellation functional unit 56 There is the first restriction push part 59 being such as made up of stretching spring.This first restriction push part 59 will First restriction cancellation functional unit 56 limits holding section 57 from operation and leaves the first non-of main operating parts 50 Lock position (position of Fig. 6) limits the notch 51 of holding section 57 and main operating parts 50 to operation Engage thus limit the first lock position (position of Fig. 5) pushing of the action of main operating parts 50.That is, In the case of being not loaded with operating physical force at the first restriction cancellation functional unit 56 and main operating parts 50, First restriction cancellation functional unit 56 is pushed from the first unlatched position by the first restriction push part 59 And return to the first lock position.
According to such structure, if the first restriction cancellation functional unit 56 is configured in the first non-locking position Put and start the action of main operating parts 50, even if then hands to be withdrawn the first restriction cancellation functional unit 56, Outside first restriction cancellation functional unit 56 also can be with the rotation section 50b of the main operating parts 50 in action Side face abuts, and stops the recovery towards the first lock position.On the other hand, if main operating parts 50 Operation terminate and by making releasing parts 41 return to restriction site from the active force of main push part 49, Then by the first restriction cancellation functional unit 56 will be made certainly from the active force of the first restriction push part 59 Recover to the first lock position dynamicly.I.e., it is intended to the protector that stroller 10 is folded, at functional unit The operation of 50 start before this section during, as long as overcome the first restriction push part 59 by first limit Releasing functional unit 56 moves just may be used to the first unlatched position.Additionally, at the expansion shape of stroller 10 Under state, the first restriction cancellation functional unit 56 automatically recovers to the first lock position, it is possible to effectively prevent The only folding operation of unexpected stroller 10 (stroller main body 11).
Additionally, as it is shown in figure 5, in the first unlatched position, abut with notch 51 and limit main operation The operation of the action of parts 50 limits the bearing surface 57a of holding section 57 with the first restriction cancellation functional unit 56 is parallel relative to the glide direction of shell 95.Therefore, it is positioned at when the first restriction cancellation functional unit 56 During the first lock position, even if being loaded the power being intended to operate main operating parts 50, via bearing surface 57a The power being transferred to the first restriction cancellation functional unit 56 also will not be towards making the first restriction cancellation functional unit 56 slide directions effect, or at least will not be formed make first restriction cancellation functional unit 56 slide Bigger power.Therefore, it is possible to be effectively prevented because maloperation etc. causes stroller main body 11 unexpectedly to start Jackknife action.
It follows that the second operation limiting mechanism 60 is illustrated.As it has been described above, the second operation restriction machine Structure 60 has the second restriction cancellation functional unit 61, and this second restriction cancellation functional unit 61 is by being grasped Work can be from the second lock position (figure limiting the operation using main operating parts 50 for releasing parts 41 The position of 7) mobile to the of the operation that can carry out using main operating parts 50 for releasing parts 41 Two unlatched position (position of Fig. 8～Figure 10).It addition, this second restriction cancellation functional unit 61 If moved to the second unlatched position from the second lock position by operation, the second non-locking position will be held in Put.Second restriction cancellation functional unit 61 for the holding of the second unlatched position, can by this second Restriction cancellation functional unit 61 is positioned at the second unlatched position and the first restriction cancellation functional unit 56 Under the state of the first unlatched position, operate main operating parts 50 release.
As shown in Figure 7 and Figure 8, second operation limiting mechanism 60 have be connected to second restriction cancellation behaviour Make the operation limiting part 70 of parts 61.As it is shown in fig. 7, when the second restriction cancellation functional unit 61 When the second lock position, operation limiting part 70 enter at least partially release parts 41 from Restriction site moves in the mobile route of releasing position.If that is, the second restriction cancellation functional unit 61 It is positioned at the second lock position, then releases parts 41 and will be unable to move to releasing position from restriction site, it is impossible to Implement the jackknife action for stroller 10 (stroller main body 11).That is, the second operation limiting mechanism 60 block the action of incompatible restriction cancellation parts 41 with releasing parts 41, it is possible to limit and use main operating parts 50 for releasing the operation of parts 41.
In the example in the figures, limiting part 70 is operated via axis of rocking parts 71 with the side that can shake Formula is linked to support parts 91.Operation limiting part 70 can be by the second restriction cancellation functional unit 61 clamped positions configured when being positioned at the second lock position (position of Fig. 7) and in the second restriction cancellation Shake between the clamped position (position of Fig. 8) that functional unit 61 is configured when being positioned at the second unlatched position Move and move.
Operation limiting part 70 has the contact site contacted when being positioned at clamped position with releasing parts 41 70a.In the example in the figures, from parallel for the shake axis 71a direction with operation limiting part 70 In the case of observation, namely in Fig. 7 and Fig. 8, at the operation limiting part 70 shown in Fig. 7 In the case of being configured at clamped position, link contact site 70a and the operation limiting unit of operation limiting part 70 The direction da of the shake axis 71a of part 70, with release parts 41 from restriction site towards release position Moving direction (namely, the long side direction of principal part 37) parallel, or relative to releasing parts 41 From restriction site trend towards release position moving direction and towards with operation limiting part 70 be configured at Contrary lopsidedness during situation (situation of Fig. 8) of non-engagement position.According to such structure, work as behaviour It is restricted parts 70 when being configured at clamped position, even if applying the power being intended to operate main operating parts 50, Operation is made to limit via contact site 70a to the power the most not court of operation limiting part 70 transmission from releasing parts 41 The direction effect of parts 70 processed shake, or the most do not produce make operation limiting part 70 shake bigger Power.Therefore, it is possible to be effectively prevented because maloperation etc. causes stroller main body 11 surprisingly to start to fold to move Make.
As shown in Figure 7 and Figure 8, the second restriction cancellation functional unit 61 is with can be along the master of handle 36 The mode slided on the long side direction of this handle 36 in portion 37 is arranged.Second restriction cancellation functional unit 61 Being formed as tubular as an example, principal part 37 is by the second restriction cancellation functional unit 61.Such as figure Shown in 7 and Fig. 8, the second restriction cancellation functional unit 61 has and is formed through in the principal part of handle 36 The holding pin 62 of the first elongated hole 37a of 37.Second elongated hole 37b extends along the long side direction of principal part 37, Engaged with keeping pin 62 by this second elongated hole 37b, thus mark off the second restriction on handle 36 Release the slidably scope of functional unit 61.
Second restriction cancellation functional unit 61 can carry out use main operating parts 50 for releasing parts Second unlatched position of the operation of 41, is positioned at the slidably scope of the second restriction cancellation functional unit 61 In top.On the other hand, the second restriction cancellation functional unit 61 use main operating parts 50 for Release the second lock position that the operation of parts 41 is limited, be positioned at the lower section of the second unlatched position.That is, Second restriction cancellation functional unit 61 is configured at the second locking easily by gravity from the second unlatched position Position.Therefore, the second operation limiting mechanism 60 more effectively function, it is possible to be effectively prevented baby Youngster's vehicle main body 11 is unexpected starts jackknife action.
Inner face at the second restriction cancellation functional unit 61 is grasped by the second restriction cancellation being made up of tubular Make parts 61 to bloat laterally and form elongated slot 61c.Elongated slot 61c is along linking the second lock position and the The long side direction of the principal part 37 in the direction of two unlatched position, i.e. handle 36 extends.On the other hand, it is subject to Push away protrusion tab 86 to highlight laterally from the principal part 37 of handle 36.Pushed away protrusion tab (protrusion tab) 86 to receive It is dissolved in elongated slot 61c.Additionally, except above-mentioned holding pin 62 is in addition to the engaging of the second elongated hole 37b, Utilize by pushing away protrusion tab 86 guiding incompatible with the card of elongated slot 61c the second restriction cancellation functional unit 61 relative In the slip of handle 36, it is possible to support the slip carrying out the second restriction cancellation functional unit 61 smoothly.
Between elongated slot 61c and protrusion tab 86, it is provided with the second restriction being such as made up of compression spring push Parts 89.This second limit push part 89 from the second unlatched position shown in Fig. 8 towards Fig. 7 institute The second lock position shown pushes the second restriction cancellation functional unit 61.That is, the second restriction cancellation operating portion Part 61 utilizes from the second active force limiting push part 89, is not protecting in the way of hereinafter describing Under the state being held in the second unlatched position, pushed and to the first lock position from the second unlatched position Return.In such a configuration, the mechanism for pushing the second restriction cancellation functional unit 61 is arranged at handle The outside of hands 36, therefore, it is possible to effectively utilize the inner space of handle 36.Such as, it is not necessary to excessively increase Big or increase thick handle 36, just can will release the second restriction cancellation functional unit 61 for the second non-locking The mechanism described later of the holding of position is configured at the inside of handle 36.
Additionally, as shown in Fig. 9 and Figure 10, by pushing away protrusion tab 86 through being formed from the principal part of handle 36 The inserting hole (the second inserting hole 37d) of 37 is embedded into and is held in be fixed in the inside of principal part 37 described later Shell 80.
As shown in Figure 7 and Figure 8, set in the way of in the handle 36 that can submerge from the principal part 37 of handle 36 It is equipped with the holding member 85 being projected toward the outside.The holding member 85 holding set by inside by handle 36 Push part 88 is pushed towards outside.On the other hand, the second restriction cancellation operation of tubular is being formed as Parts 61 are formed by receiving the recess 61a of holding member 85.Recessed with this by the front end of holding member 85 Portion 61a engages, and makes the second restriction cancellation functional unit 61 be held in the second lock position.Example in diagram In son, recess 61a is formed as the through hole of through second restriction cancellation functional unit 61.But, recessed Portion 61a can also be formed as the bottom outlet that has with bottom.
It addition, as shown in Figure 7 and Figure 8, the second restriction cancellation functional unit 61 with recess 61a Adjacent position has guide portion 61b.Guide portion 61b engages with the front end of holding member 85, and comprises The inclined-plane that holding member 85 is guided to recess 61a.Guide portion 61b is at the second restriction cancellation functional unit The position in 61 fronts being in recess 61a from the second lock position when sliding to the second unlatched position, if It is placed in the second restriction cancellation functional unit 61.Guide portion 61b, above recess 61a, is configured to wall The wide diameter portion expanded laterally.According to such guide portion 61b, it is possible to by from the prominent holding of handle 36 Parts 85 guide smoothly and stably along the direction orthogonal with the long side direction of handle 36 to recess 61a, And the second restriction cancellation functional unit 61 is held in the second unlatched position.Thereby, it is possible to it is easy and steady Surely the folding operation of stroller is implemented.
As it has been described above, the second restriction cancellation functional unit 61 of the second operation limiting mechanism 60 and operation limit Parts 70 processed are separately positioned.Therefore the second operation limiting mechanism 60 has connection member 68 as by the The action of two restriction cancellation functional units 61 is to the transfer unit of operation limiting part 70 transmission.Connecting portion Part 68 is arranged between the second restriction cancellation functional unit 18 and operation limiting part 70, links the second limit System releases functional unit 18 and operation limiting part 70.Connection member 68 is by metal wire (steel wire) etc. Known unit is constituted, as an example can by formed above-mentioned transfer unit 43 by soft line Deng the thread-like member of composition and by this thread-like member cartridge of through insertion in the way of can sliding Combination is constituted.
In the example in the figures, connection member 68 is the bar-shaped parts that can erect alone, such as by can The metal bar erected alone is constituted.One end of connection member 68 is bent into ring-type, by by above-mentioned holding Pin 62 is through to be inserted in this colyliform portion and is supported on the second restriction cancellation operating portion via holding pin 62 Part 61.The other end of connection member 68 is bent over, and along and operation limiting part 70 shake axis 71a Parallel direction extends and then through operation limiting part 70.Operation limiting part 70 can be with connecting portion Rotate relative to connection member 68 centered by the other end of part 68.According to such connection member 68, energy Enough by the most cheap and simple structure, the action of the second restriction cancellation functional unit 61 is limited to operation Parts 70 processed transmit.
It addition, as shown in Figure 7 and Figure 8, in the principal part 37 of handle 36, shell 80 is fixed.Shell 80 are formed by the first component 81 being mutually fitted together to and second component 82.As shown in Fig. 9 and Figure 10, Being internally formed for the above-mentioned receiving space 83 keeping releasing parts 44 configuration at shell 80.Keep Release parts 44 and can move (energy along the long side direction of the principal part 37 of handle 36 in receiving space 83 Enough slips).As it has been described above, have the First Line of the first connection member 45 keeping releasing parts 44 to connect One end of shape parts 45a and one end of the second thread-like member 46a of the second connection member 46.Therefore, Shell 80 be provided for making the first thread-like member 45a pass through first by hole 83a with for making second Thread-like member 45b pass through second by hole 83b.
Merge with the second restriction cancellation functional unit 61 card and the second restriction cancellation functional unit 61 is locked to The holding member 85 of the second unlatched position is held in shell 80.Additionally, be configured at shell 80 In holding release parts 44, main operating parts 50 operated and released parts 41 from restriction site to When releasing position pull-up, to merge with holding member 85 card, holding member 85 is guided to shell 80 Mode action.According to such structure, it is possible to by extremely simple structure, with main operating parts 50 Operations linkage automatically terminate the second restriction cancellation functional unit 61 guarantor for the second unlatched position Hold.
As shown in Fig. 9 and Figure 10, holding member 85 has expanding flange part 85b, is positioned at flange The portion that the charges into 85a and support 85c of the both sides of portion 85b.Charge into portion 85a in the way of can sliding Through be inserted into first component 81 arrange inserting hole 81a and handle 36 principal part 37 arrange insert Through hole (the first inserting hole) 37c.Charge into portion 85a while being inserted through hole 81a and inserting hole 37c and guiding While sliding relative to shell 80, thus highlight laterally from handle 36, it is possible to the second restriction cancellation The recess 61a engaging of functional unit 61.On the other hand, in the inserting hole 81a phase with first component 81 To position, second component 82 be formed supporting recess 82a.It is supported with such as at supporting recess 82a The holding push part 88 being made up of compression spring.Keep push part 88 charging into holding member 85 Portion 85a pushes holding member 85 from the mode that handle 36 highlights laterally.On the other hand, by overcoming Holding member 85 is directed in shell 80 by the active force keeping push part 88, it is possible to release maintaining part The engaging of part 85 and the recess 61a of the second restriction cancellation functional unit 61.
In the example in the figures, the support 85c of holding member 85 is inserted into by compression helical spring structure In the holding push part 88 become, and support holding push part 88.It addition, keep push part 88 End abut with the flange part 85b of holding member 85.According to such mode, utilize holding member The portion that the charges into 85a of 85 is inserted through the combination that hole 81a and inserting hole 37c guides, it is possible to stable and smooth Support and carry out the holding member 85 action relative to handle 36.
As shown in Fig. 9 and Figure 10, keep releasing parts 44 and be configured at the flange part of holding member 85 Between the bottom surface of the receiving space 83 of 85b and formation first component 81.Keep the thickness releasing parts 44 And it is non-constant.Keep the thickness releasing parts 44, make releasing parts 41 from restriction site to releasing position Keeping when putting mobile release the movement of parts 44 to be in side, front relatively thin, release parts in this holding The movement of 44 to be in side, rear thicker.Thus, by the long side direction of the principal part 37 along handle 36 The holding of movement releases parts 44 and engages with holding member 85, it is possible to make holding member 85 towards with principal part Direction, typical case that the long side direction of 37 intersects move towards the direction orthogonal with the long side direction of principal part 37.
More specifically, as shown in Fig. 9 and Figure 10, keep releasing parts 44 and have relative to holding The rake 44a that the moving direction both sides of the moving direction and holding member 85 that release parts 44 tilt. The rake 44a and the holding member that keep releasing parts 44 of movement by operation main operating parts 50 The flange part 85b of 85 abuts.Rake 44a abuts with flange part 85b, thus makes holding member 85 From first component 81 side to second component one side shifting, it is possible to this holding member 85 is directed into shell In 80.Thereby, it is possible to release holding member 85 and the recess 61a of the second restriction cancellation functional unit 61 Engaging.
Additionally, be released from the second restriction cancellation functional unit 61 of the engaging with recess 61a by from the Two active forces limiting push part 89, start to move to the second lock position from the second unlatched position. That is, according to being arranged at the rake 44a keeping releasing parts 44, it is possible to release parts 44 by keeping Action is changed direction, and stably transmits to holding member 85.Thereby, it is possible to use simple structure, companion With more stable in the operation of main operating parts 50 and automatically terminate the second restriction cancellation operating portion more reliably Part 61 is for the holding of the second unlatched position.
Additionally, in the example in the figures, relative to the moving direction and the maintaining part that keep releasing parts 44 The rake 44a that the moving direction both sides of part 85 tilt is arranged at holding and releases parts 44.But, phase For keeping inclining of the moving direction both sides inclination of moving direction and the holding member 85 releasing parts 44 Tiltedly portion is being arranged at holding releasing parts 44 and holding member 85 both sides and is being only arranged at holding member Identical action effect is all can get in the case of 85.As an example, can be by flange part 85b's Rake is formed as with keeping the face releasing parts 44 relative.
It addition, as shown in Fig. 9 and Figure 10, holding member 85 extends at receiving space 83, and with join The holding being placed in receiving space 83 releases parts 44 and engages.As shown in Fig. 9～Figure 11, keep releasing Parts 44 form the through hole 44b extended along its thickness direction.Additionally, holding member 85 charge into portion The through through hole 44b keeping releasing parts 44 of 85a also extends.According to such structure, it is possible to along not The holding that the most orthogonal equidirectional direction is moved releases parts 44 and holding member 85 phase mutual designation Respective action.Thus, keep releasing parts 44 and holding member 85 can be suitable along predetermined direction Profit action.In addition it is possible to the holding moved along different directions is released parts 44 and holding member In the 85 narrow and small receiving spaces 83 being arranged in shell 80.
The most in the example in the figures, as shown in figure 11, rake is formed in the both sides of through hole 44b 44a, the flange part 85b of the holding member 85 of foreign steamer Guo the most shown in broken lines can be two positions Put and engage with rake 44a.Thus, by using the transfer unit 43 forming folding operation mechanism 40 A part holding release parts 44, it is possible to more stably holding member 85 is directed in handle 36.
Additionally, in the example in the figures, through hole 44b is formed, by maintaining part keeping releasing parts 44 Part 85 through insertion this through hole 44b, but be not limited to that this, it is also possible to holding is released parts 44 The through through hole being inserted in holding member 85 formation.
Hereinafter, carry out arranging explanation to order when folding the stroller 10 being made up of above structure.
First, make the second restriction cancellation functional unit 61 of the second operation limiting mechanism 60 along handle 36 Principal part 37 slide into the second unlatched position from the second lock position.By this operation, make from handle The holding member 85 that 36 highlight laterally embeds the recess 61a of the second restriction cancellation functional unit 61, will Second restriction cancellation functional unit 61 is held in the second unlatched position.Second restriction cancellation functional unit 61 from the second lock position towards the movement of the second unlatched position via connection member 68 be transferred to behaviour It is restricted parts 70.Operation limiting part 70 is from stoping folding operation mechanism 40 from releasing parts 41 Restriction site is towards releasing the clamped position of movement of position to being configured at restriction site and releasing between position Release parts 41 mobile route outside clamped position move.That is, the second restriction cancellation operating portion is utilized The operation of part 61 releases by the second operation limiting mechanism 60 for releasing the restriction of the movement of parts 41.
Additionally, the glide direction of the second restriction cancellation functional unit 61 is along the long side direction of handle 36. On the other hand, the direction that holding member 85 is pushed by the outside towards handle 36 is the long limit side with handle 36 To the direction intersected, it is typically the direction orthogonal with the long side direction of handle 36.Therefore, it is effectively prevented The situation that second restriction cancellation functional unit 61 is surprisingly released with the engaging of holding member 85.It addition, Being in the moving process towards the second unlatched position of the second restriction cancellation functional unit 61 is recessed The position in the front of portion 61a is configured with guide portion 61b, this guide portion 61b and the front end of holding member 85 Engage thus holding member 85 is pressed into the inside of handle 36, and the front end of this holding member 85 is drawn It is directed at recess 61a.Therefore, it is possible to stablize and successfully realize the second restriction cancellation functional unit 61 and protect Hold the engaging of parts 85.
