In the example in the figures, a pair of of keeping body 55 is supported on each axle portion 51a of handle main body 51.Keeping body 55 is along setting about The length direction of the part for being provided with the keeping body 55 in handle main body 51, can move relative to handle main body 51.Such as Fig. 2 institutes Show, in each axle portion 51a of handle main body 51, a pair of of limiter 51c has been disposed separately along the length direction of axle portion 51a. Limiter 51c is formed as the part relative to axle portion 51a enlarged-diameters.A pair of of limiter 51c regulations keeping body 55 can move Dynamic scope.Keeping body 55 can be moved as the region between a pair of of limiter 51c along the length direction of axle portion 51a.

As shown in Fig. 6 and Fig. 7, keeping body 55 has for the axle portion 51a cylindrical body parts 56 passed through and is supported on tubular The guide portion 57 of main part 56 and holding section 58.As shown in fig. 7, holding section 58 has the supporting part 58a being open downwards.Such as Shown in Fig. 5, position holding member 35,36 is covered from above by holding section 58, so that keeping body 55 and position holding member 35th, 36 relative movement to the direction orthogonal with the length direction of axle portion 51a is restricted, and handle 50 is maintained at first position Or the second place.As shown in fig. 6, each keeping body 55 has a pair of of guide portion 57 positioned at the both sides of holding section 58.Such as Fig. 2 institutes Show, cylindrical body part 56 is between separated a pair of of guide portion 57 along the longitudinal direction.Handle is in first position and the second place Between when swinging, in the position than holding section 58 closer to front end, the guide portion 57 adjacently set with the holding section 58 contacts To position holding member 35,36.Guide portion 57 has the guide surface 57a contacted with position holding member 35,36.Guide surface 57a As inclined plane.Position holding member 35,36 is touched by guide surface 57a, so that length of the keeping body 55 along axle portion 51a Direction separates and side movement upwards with position holding member 35,36.

Here, handle 50 also has the second force application part 54 to exert a force to keeping body 55.Second force application part 54 Exert a force along the length direction direction of axle portion 51a with 35,36 close direction of position holding member to keeping body 55.That is, Second force application part 54 acts on keeping body 55 to maintain engaging of the keeping body 55 with position holding member 35,36.

Second force application part 54 is for example formed by the component that elastic force is produced because of material or shape.In example illustrated In, the second force application part 54 is formed by compression spring.In addition, in the example in the figures, handle 50, which also has, is arranged on handle master Cover board 53 on body 51.As shown in figs.5 and 6, cover board 53 forms storage space rs at it between handle main body 51.Second Force application part 54 is configured in storage space rs.As shown in figure 8, in cover board 53, formed with groove 53a.As shown in figure 5, groove 53a Length direction along the axle portion 51a of handle main body 51 extends.Storage space rs is communicated by groove 53a with outside.On the other hand, As shown in Fig. 5~Fig. 7, keeping body 55 has the protuberance 56a stretched into by groove 53a in storage space rs.It is as shown in fig. 7, prominent Go out portion 56a to stretch out from cylindrical body part 56 towards the inner space delimited by the cylindrical body part 56.It is as shown in figure 5, prominent 56a supportings in portion form the lower end of the compression spring of the second force application part 54.Therefore, protuberance 56a passes through the second force application part 54 It is pressed downwards.It should illustrate that in the example in the figures, the limiter 51c of downside is formed as a part for cover board 53.

Next, functional unit 60 is illustrated.As shown in Fig. 9 and Figure 10, functional unit 60 so as to action Mode is arranged at handle main body 51.As shown in Fig. 9 and Figure 10, functional unit 60 makes state maintaining member by being acted 45 actions.That is, functional unit 60 is set with the setting of state maintaining member 45.

Functional unit 60 can be between the operating position shown in the off position and Figure 10 shown in Fig. 9 along handle master The length direction movement of the part for being provided with functional unit 60 in the axle portion 51a of body 51.Functional unit 60 is by being accommodated in hand The 3rd force application part 64 (with reference to Fig. 9) of the axle portion 51a of handle 50, is exerted a force from the lateral off position of operating position.That is, operate Component 60 is not in the case where being applied in external force, by the active force from the 3rd force application part 64, positioned at than operating position Closer to the off position of lower section.As an example, functional unit 60 is by operation tool for transmitting (not shown), with setting Link in the far-end operation device 52 of the pars intermedia 51b of handle 50 (with reference to Fig. 1).Moreover, by operating far-end operation device 52, Functional unit 60 can be made to be moved from operating position to off position.

As shown in Figure 15 and Figure 16, the operation that functional unit 60 has operation base portion 61 and protruded from operation base portion 61 is dashed forward Go out portion 62.Here Figure 15 be in the width direction outside represent functional unit 60 stereogram, Figure 16 be in the width direction inner side table Show the top view of functional unit 60.As shown in figure 9, operation base portion 61 is installed on the axle portion 51a of handle main body 51.Such as by Fig. 9 with The comparison of Figure 10 is it is understood that operation base portion 61 can be along the length direction of the axle portion 51a of handle main body 51 relative to the axle portion 51a is slided.In addition, operation protuberance 62 operates base portion 61 towards being provided with the axle portion 51a relative to handle main body 51 The inner side of the orthogonal direction of partial length direction, more specifically width, stretches out from operation base portion 61.On the other hand, As shown in figure 9, outside of the support plate 48 of state maintaining member 45 from main part 46 to width is stretched out.

Moreover, if functional unit 60 is moved from off position to operating position, operation protuberance 62 from below with The support plate 48 of state maintaining member 45 abuts, and state maintaining member 45 is pressed from restriction site towards position is released. That is, in the case where handle 50 is located at first position, by making functional unit 60 be moved from off position to operating position, energy State maintaining member 45 is enough set to be moved from restriction site to position is released.Thereby, it is possible to carry out first connecting rod 20 relative to the 3rd The relative rotation of connecting rod 30.

Especially, as shown in Figure 11~Figure 14, functional unit 60 passes through the hand relative to the handle 50 positioned at first position Handle main body 51 carry out action can pressed state maintaining member 45 and it and is passed through from restriction site to position movement is released Relative to the handle main body 51 of the handle 50 positioned at the second place acted also can pressed state maintaining member 45 and make it Moved from restriction site to position is released.Here Figure 11~Figure 14 is the side view on the setting position periphery for representing first connecting rod 20 Figure.But in order to make it easy to understand, in Figure 11 and Figure 12, it is represented by dotted lines the section below and state of first connecting rod 20 Maintaining member 45, makes handle main body 51 with solid line and functional unit 60 exposes and represents.

As Figure 16 is best shown in, there is the operation protuberance 62 of functional unit 60 first contact surface 62a and second to connect Contacting surface 62b.First, the first contact surface 62a is configured at relative to length of the axis of oscillation sa of handle main body 51 along axle portion 51a The position of direction offset.As shown in figs. 11 and 12, in the case where handle 50 is configured at first position, the axle portion of handle 50 The master connecting-rod part 21 of 51a and first connecting rod 20 extend substantially in parallel.Therefore, if functional unit 60 is from off position to behaviour Make position movement, i.e. if functional unit 60 is moved upward along the axle portion 51a of the handle 50 positioned at first position, grasp The the first contact surface 62a for making component 60 is abutted with the support plate 48 of state maintaining member 45 from below, can be by 48 edge of support plate First connecting rod 20 to press upward.

On the other hand, the second contact surface 62b becomes following inclined plane, i.e., relative to functional unit 60 from off position The moving direction of (with reference to Figure 13) towards operating position (with reference to Figure 14) tilts and from the moving direction of aforesaid operations component Front side is separated towards rear side with handle main body 51, and the moving direction of the functional unit is from off position towards operating position Direction.In other words, as Figure 16 is best shown in, length sides of the second contact surface 62b from axis of oscillation sa relative to axle portion 51a To ld towards downside tilted rearward.Therefore, as shown in Figure 13 and Figure 14, swung forwards in handle 50 and be configured at second In the case of position, the second contact surface 62b is from the downside alongst of the master connecting-rod part 21 of first connecting rod 20, with state The support plate 48 of maintaining member 45 faces.Especially, as shown in Figure 13 and Figure 14, the feelings of the second place are configured in handle 50 Under condition, i.e. if the axle portion 51a of handle main body 51 is rolled upward and forwards tiltedly, the second contact surface 62b is along substantially Anteroposterior direction extends.If functional unit 60 is moved from off position to operating position, the second contact of functional unit 60 Face 62b can be abutted with the support plate 48 of state maintaining member 45 from below, and support plate 48 is pressed upward.

In the example in the figures, the functional unit 60 positioned at off position is separated with state maintaining member 45.That is, in hand Handle 50 is located at first position and in the case that keeping body 55 is located at off position, i.e. in the state of shown in Figure 11, operation portion Part 60 is separated with keeping body 55.In addition, in the case where handle 50 is located at the second place and keeping body 55 is located at off position, That is, in the state of shown in Figure 13, functional unit 60 is separated with keeping body 55.On the other hand, as shown in figure 16, functional unit 60 Operation protuberance 62 also there is crowning 62c between the first contact surface 62a and the second contact surface 62b.From handle 50 Relative to main body frame 12 axis of oscillation sa to crowning 62c distance dx ratios from axis of oscillation sa to the first contact surface Distance dy long and ratio untill the part 62a1 abutted in 62a with crowning 62c is from axis of oscillation sa to the second contact surface 62b In with crowning 62c adjoining part 62b1 untill distance dz long.That is, the first contact surface 62a connect near crowning 62c with And second contact surface 62b protrusion.

Next, the wheel holding unit 70 of the leg 14,16 to being fixed on baby's vehicle main body 11 illustrates.Before being fixed on Wheel is remained to rotate and remain wheel and can also turned to by the wheel holding unit 70 of leg 14.That is, before being fixed on The wheel holding unit 70 of leg 14 forms so-called castor.The wheel holding unit 70 for being fixed on back leg 16 can to wheel progress Rotating holding, wheel can also be remained and can turned in the same manner as the wheel holding unit 70 for being fixed on foreleg 14. The wheel holding unit 70 for being fixed on foreleg 14 and the wheel holding unit 70 for being fixed on back leg 16 are all configured to the feelings of castor Under condition, according to the swing position of handle 50, in the wheel holding unit 70 of the front side on the direct of travel of perambulator 10 The steering of wheel can be allowed to, the wheel in the wheel holding unit 70 of the rear side on the direct of travel of perambulator 10 Steering can be restricted.The permission of the steering of wheel and the switching of limitation can carry out manually, or can for example such as As JP2002-284015A is disclosed, automatically carried out with the swing of handle 50.

The action of the perambulator 10 formed to the structure more than illustrates.Above-mentioned perambulator 10 can be by handle 50 In the first position being fixed on shown in Fig. 1 and the second place shown in Fig. 2 either one and use.Is held in handle 50 In the case of one position, operator (Protector) can be from the position of the back leg side of the perambulator 10 of the rear side as infant Handle 50 is held, perambulator 10 is promoted in a manner of infant is towards the front of direct of travel.At this time, the foreleg side of perambulator 10 As in front of direct of travel.On the other hand, in the case where handle 50 is held in the second place, operator can from infant The position of the foreleg side of the perambulator 10 faced holds handle 50 and promotes perambulator 10.At this time, the back leg side of perambulator 10 becomes In front of into direct of travel.

In the case of changing in the position for making handle 50 between first position and the second place, first, operation handle 50 keeping body 55.Make handle 50 from first position (back side pushing position) to the second place (facing pushing position) movement In the case of, the length direction along the axle portion 51a of handle main body 51 lifts keeping body 55 upward.The operation passes through to keeping Body 55 assign with the external force of the active force of the second force application part 54 confrontation and implement.If keeping body 55 is relative to handle main body 51 Mobile, then the first position holding member 35 for being accommodated in the supporting part 58a of keeping body 55 exposes from supporting part 58a.Thus, handle 50 engagings with main body frame 12 are released from, and handle 50 can be swung relative to main body frame 12.

If making handle 50 reach near the second place, second place holding member 36 starts to contact keeping body 55 Guide surface 57a.Abutted by second place holding member 36 with guide surface 57a, along the length direction of axle portion 51a by keeping body 55 ejections upward.If handle 50 reaches the second place, the releasing of second place holding member 36 connects with guide surface 57a's Touch, keeping body 55 can move downwards along the length direction of axle portion 51a.The result is that by from the second force application part 54 Active force so that keeping body 55 automatically moves downwards, the supporting part 58a of keeping body 55 is covered in second place maintaining part Part 36.Thus, handle 50 and the opposing oscillatory of main body frame 12 are restricted, and handle 50 is held in the second place.

It should illustrate that the ejection of keeping body 55 is acted using the contact with guide surface 57a of second place holding member 36, it is right Resist the active force of the second force application part 54 and implement.Operator (Protector) is protected by perceiving 36 ejection of second place holding member Body 55 is held, handle 50 can be perceived close to the second place as target location.Therefore, operator can make the swing of handle 50 Gradually slow down and terminate.Therefore, it is possible in the case where not giving big impact to main body frame 12, change the swing of handle 50 Position.

In the case where making handle 50 be swung from the second place to first position, implement and make handle 50 from above-mentioned first The almost identical operation of situation that position is swung to the second place.That is, only need that first, the keeping body 55 of handle 50 is carried upward Draw, next, making handle 50 be moved to first position from the second place.

However, when making the handle 50 swing between the first location and the second location, functional unit 60 also with handle main body 51 Rotated together using axis of oscillation sa as center relative to main body frame 12.Therefore, the first contact surface 62a, crowning 62c and Second contact surface 62b is reached in the order or by the length direction of the order opposite with the order along master connecting-rod part 21 and shape The position that the support plate 48 of state maintaining member 45 faces.Moreover, compared with the first contact surface 62a and the second contact surface 62b from The separated crowning 62c of axis of oscillation sa are in the position that the length direction along master connecting-rod part 21 and support plate 48 face, with branch Board 48 abuts and presses support plate 48 upward.Here, including the state maintaining member 45 of support plate 48 is applied by first Power component 49 is exerted a force downwards.Therefore, operator is in the case where making handle swing between the first location and the second location, It will appreciate that swinging operation is smoothed out this situation by 60 ejection state maintaining member 45 of sense operation component.In addition, , can be by positioned at the handle 50 of first position and the centre position of the second place by the active force from the first force application part 49 It is directed to first position or the second place.It should illustrate that with state maintaining member 45 caused by the swing of handle 50 Amount of movement it is very slight, be limit engaging protrusion 47 will not from third connecting rod 30 limitation engaging recessed part 33 extract degree.Change Yan Zhi, state maintaining member 45 will not be moved to reach because of caused by the swing with handle 50 releases position.

Next, to the perambulator 10 that the structure more than is formed is said from the action during state folding of expansion It is bright.Above-mentioned main body frame 12 can be folded by relatively rotating each component parts.Specifically, by using hand Handle 50 and by first connecting rod 20, top lifts briefly backwards, put down afterwards so that third connecting rod 30 relative to back leg 16 along Fig. 2 In rotationally clockwise.With the operation, handrail 19 and second connecting rod 25 up time along Fig. 2 relative to first connecting rod 20 Pin direction rotates.Operation in this way, first connecting rod 20 configures substantially in parallel with foreleg 14 during side view, and 50 phase of handle Decline for the position of the axis of oscillation sa of main body frame 12.As above, being capable of folding baby car 10.

Particularly, in the example in the figures, for handle 50, on the one hand it is connected in the end portion of handle main body 51 Main body frame 12, is on the other hand connected to main body frame 12 via keeping body 55.Moreover, keeping body 55 is relative to handle main body 51 The handle main body 51 can be movably supported on.Therefore, as shown in Figure 3 and 4, handle 50 be held in first position and In the case of either one in the second place, main body frame 12 can be folded.In addition, handle 50 be held in first position with And in the case of either one in the second place, handle 50 is relative to the axis of oscillation sa of main body frame 12 all by main body frame 12 fold up in the state of be located at state position further below than expansion.That is, in baby's vehicle main body 11 including handle 50 And in perambulator 10, it can make in the state of being folded relative to the state of expansion compact in size.

It should illustrate that as handle 50 relative to the bottom of the handle main body 51 of a link position of main body frame 12 Divide by using shaft member 34, in first connecting rod 20 and the link position of second connecting rod 25, be connected to main body frame 12.In handle 50 are held in the state of first position, and keeping body 55 is connected to main body frame by engaging with first position holding member 35 12.Moreover, first position holding member 35 is fixed on first connecting rod 20.That is, in the state of handle 50 is held in first position, Handle 50 is connected to first connecting rod 20 two positions.In the state of handle 50 is held in first position, start perambulator 10 Jackknife action in the case of, handle 50 can not be relative to 20 relative motion of first connecting rod.Therefore, in keeping body 55 and first In the case that position holding member 35 starts jackknife action in the state of engaging, keeping body 55 cannot be moved relative to handle main body 51 It is dynamic.In the jackknife action of the perambulator 10, the second force application part 54 continuingly acts on keeping body 55, with maintain keeping body 55 with The fastening state of first position holding member 35.

On the other hand, in the state of handle 50 is held in the second place, keeping body 55 by with second place maintaining part Part 36 engages, and is connected to main body frame 12.Moreover, second place holding member 36 is not secured to the company of first connecting rod 20 and second Any one in bar 25, and it is affixed to handrail 19.That is, in the state of handle 50 is held in the second place, handle 50 connects To the different components of the relative motion in the jackknife action of main body frame 12.Specifically, it is held in the second place in handle 50 In the state of, for handle 50, on the one hand the link position with first connecting rod 20 and second connecting rod 25 is connected, on the other hand It is connected with handrail 19.Moreover, such as from the comparison of Fig. 2 and Fig. 4 it is understood that by folding main body frame 12, handle 50 and body frame Two link positions of frame 12 are separated from each other.Therefore, opened in the state of keeping body 55 engages with second place holding member 36 In the case of beginning jackknife action, keeping body 55 is acted relative to handle main body 51.More specifically, keeping body 55 is along handle master The axle portion 51a of body 51, to from the separated sides of axis of oscillation sa, i.e. upside is mobile.The keeping body 55 is relative to handle main body 51 Action confrontation the active force from the second force application part 54 and implement.Therefore, in the jackknife action, the second force application part 54 Exert a force to keeping body 55 towards second place holding member 36.That is, the second force application part 54 is in the jackknife action, continuous action In keeping body 55, to maintain the fastening state of keeping body 55 and second place holding member 36.

However, it is necessary to make state maintaining member 45 from restriction site to unrestricted before the jackknife action of perambulator 10 Move position.As described above, being arranged at the functional unit 60 of handle 50, no matter handle 50 is located at first position and the second place Where, by being acted relative to handle main body 51, can pressed state maintaining member 45 and make it from limit Position processed, which is moved to, releases position.

Specifically illustrate, first, in the case where handle 50 is located at first position, as shown in figure 11, functional unit 60 The first contact surface 62a from 48 face of support plate of the downside of the length direction along master connecting-rod part 21 and state maintaining member 45 It is right.Moreover, as shown in figure 12, if functional unit 60 is moved along the upward sides of axle portion 51a, state maintaining member 45 is operated The first contact surface 62a pressings of component 60, are moved upward along the length direction of master connecting-rod part 21.As a result, pass through operation Operating position movement shown in component 60 from the off position to Figure 12 shown in Figure 11, so that state maintaining member 45 is from Figure 11 Releasing position from restriction site to Figure 12 movement.In the case where handle 50 is located at the second place, as shown in figure 13, operation portion Support plates 48 of the second contact surface 62b of part 60 from the downside of the length direction along master connecting-rod part 21 and state maintaining member 45 Face.Moreover, as shown in figure 14, if functional unit 60 is moved along the upward sides of axle portion 51a, state maintaining member 45 is grasped Make the second contact surface 62b pressings of component 60, be moved upward along the length direction of master connecting-rod part 21.As a result, pass through behaviour Make the operating position movement shown in component 60 from the off position to Figure 14 shown in Figure 13, so that state maintaining member 45 is from figure Releasing position movement of 13 restriction site to Figure 14.That is, no matter which in first position and the second place handle 50 be located at A position, by similarly operating far-end operation device 52, can operate functional unit 60, make state maintaining member 45 from limitation Moved to position is released position.

As mentioned above, in the present embodiment, perambulator 10 has and can be deformed from unfolded state to folded state Main body frame 12 and the handle of main body frame 12 is connected in a manner of it can swing between the first location and the second location 50.Main body frame 12 has folding of the restriction site that the jackknife action in perambulator 10 is restricted with that can carry out perambulator 10 The state maintaining member 45 that can be moved between the releasing position of folded action.Handle 50 has the handle for being connected to main body frame 12 Main body 51 and so as to the mode of action is supported on the functional unit 60 of handle main body 51.Functional unit 60 is by relative to position Acted in the handle main body 51 of the handle 50 of first position, thus pressed state maintaining member 45 and make it from restriction site Move to position is released, and acted by the handle main body 51 relative to the handle 50 positioned at the second place, so as to press State maintaining member 45 and make its from restriction site to release position movement.According to such present embodiment, in 50, handle In the case of any one in first position and the second place, functional unit 60 can block with state maintaining member 45 Close, state maintaining member 45 is moved from restriction site to position is released.Therefore, no matter handle 50 is located at first position and Where two positions, by acting functional unit 60, can start folding operation.For example, in the moon of infant In the case of age is less, the situation of perambulator 10 is utilized to become more in the side configuration handle 50 faced with infant, so Period, can handle 50 is configured at the second place it is constant in the state of folded.In addition, in the baby that will be folded up When youngster's car 10 is unfolded, it is constant that handle 50 is configured at the second place.The step of therefore, it is possible to save the position of adjustment handle 50, carry The convenience of high perambulator 10.

In addition, in the present embodiment, functional unit 60 can move between operating position NOT-AND operation position, and from Operating position side is exerted a force towards off position.The behaviour that state maintaining member 45 is moved from off position to operating position Make component 60 to press, moved from restriction site to position is released.In the example in the figures, functional unit 60 is towards underlying Off position and exerted a force, and pressed state maintaining member 45 from below.Thus, handle 50 be configured at first position with And in the case of the second place, the functional unit 60 that is operated by antagonism power towards operating position makes state maintenance portion Part 45 acts.Therefore, it is possible to effectively prevent state maintaining member 45 from carrying out undesirable action.Thereby, it is possible to by perambulator 10 are stably maintained at the state of expansion.

And then in the present embodiment, the functional unit 60 positioned at off position is separated with state maintaining member 45.Cause This, when perambulator 10 is unfolded from folded state in the state of handle 50 is configured at first position or the second place, in shape Gap is formed between state maintaining member 45 and functional unit 60.Therefore, when perambulator 10 is unfolded, can effectively prevent in shape Clothes etc. is clamped between state maintaining member 45 and functional unit 60.

And then in the present embodiment, functional unit 60 can move between operating position NOT-AND operation position.Operation Component 60 is included in the first contact surface that state maintaining member 45 can be touched in the case that handle 50 is located at first position 62a and the second contact surface 62b that state maintaining member 45 can be touched in the case where handle 50 is located at the second place.Root According to such functional unit 60, by easily forming, the swing position regardless of handle 50, can stably ensure to grasp Make engaging of the component 60 with state maintaining member 45.

And then in the present embodiment, functional unit 60 has 61 and of operation base portion that can be slided relative to handle 50 The prominent operation protuberance 62 in direction that the length direction of the part of operation base portion 61 intersects is provided with relative to handle 50.

And then in an above-mentioned embodiment, show that first position holding member 35 and the second place are kept Component 36 with keeping body 55 in the state of engaging, the example that cannot be relatively moved relative to keeping body 55.However, such as Figure 19~ Multiple examples shown in Figure 28 are such, and position holding member 35,36 can also be to be provided with keeping body along handle main body 51 Part on length direction engage relative to the mode that keeping body 55 can relatively move with keeping body.

The first case that can relatively movably engage with second place holding member 36 as keeping body, Figure 19~Figure 21 show Keeping body 255 is gone out, Figure 22 and Figure 23 show perambulator 10, and Figure 24 and Figure 25 show the action of keeping body 255.Separately Outside, the second case that can relatively movably engage with second place holding member 36 as keeping body, Figure 26 and Figure 27 are shown Perambulator 10, Figure 28 show the action of keeping body 355.The keeping body 255 and figure of first case shown in Figure 19~Figure 25 The keeping body 355 of second case shown in 26~Figure 28 can be along in the same manner as the keeping body 55 in an above-mentioned embodiment Length direction of the handle main body 51 on the part of keeping body 255,355 is provided with is moved relative to handle main body 51.Keeping body 255th, 355 relative to handle main body 51 by moving, so that in the example in the figures, moved downwards in handle main body 51, So as to engage with first position holding member 35 and second place holding member 36.On the other hand, shown in Figure 19~Figure 25 In the keeping body 355 of second case shown in the keeping body 255 and Figure 26~Figure 28 of first case and an above-mentioned embodiment Keeping body 55 it is different, the length direction along the axle portion 51a of handle main body 51 becomes longer.First, such keeping body 255th, 355 due to positioned at operator (Protector) on hand near, so having the advantages that easily operated etc.In addition, also have There is the length direction for making keeping body 255,355 along the axle portion 51a of handle 50 to stablize relative to the relative movement of handle main body 51 Etc the advantages of.Hereinafter, using the difference from said one embodiment as center, first case and second case are said It is bright.

First, in first case, keeping body 255 has in the same manner as the keeping body 55 in an above-mentioned embodiment protects The cylindrical body part 56 for being held in axle portion 51a, the holding section 58 that can be engaged with position holding member 35,36 and it is configured at card The guide portion 57 of the both sides in conjunction portion 58.Wherein, guide portion 57 is formed in the same manner as an above-mentioned embodiment.

On the other hand, cylindrical body part 56 becomes longer compared with an above-mentioned embodiment.Such as Figure 24 and Figure 25 It is shown, in the inner face of cylindrical body part 56, the storage groove portion formed with the space as the length direction extension along axle portion 51a 56c.The upper end for storing groove portion 56c opens, but the lower end for storing groove portion 56c is closed by support foot 56d.In addition, in mounting cylinder The axle portion 51a of the handle 50 of shape main part 56, the holding projection 51e for setting oriented radial outside to protrude.Keep projection 51e from The overhang of axle portion 51a is less than the depth of storage groove portion 56c.By keeping projection 51e in storage groove portion 56c, so as to protect Hold the movement in handle main body 51 that projection 51e does not hinder keeping body 255.In storage groove portion 56c, the second force section is stored Part 54.In other words, the storage space rs that groove portion 56c forms the second force application part 54 is stored.Second force application part 54 is configured at Between holding projection 51e and support foot 56d.Second force application part 54 is for example made of compression spring, to 255 direction of keeping body Position holding member 35,36 exerts a force.In addition, in cylindrical body part 56, in the upside of its outer surface, enlarged-diameter is provided with Flange part 56b.Operator (Protector) can hold flange part 56b and operate keeping body 255.

Next, holding section 58 is being provided with the part of keeping body 255 as shown in Figure 23~Figure 25 along handle main body 51 On length direction extension.Holding section 58 can engage with first position holding member 35 and second place holding member 36. In the state of second place holding member 36 engages in the holding section 58 with keeping body 255, along the length direction of holding section 58, I.e. along handle main body 51 axle portion 51a length direction, can be relatively moved relative to holding section 58.As specific structure Into as shown in figure 20, the holding section 58 of keeping body 255 is formed as the length direction along holding section 58, i.e. along handle main body The groove 58b of the length direction extension of 51 axle portion 51a.As shown in Figure 20 and Figure 21, groove 58b is kept as with the second place End on front side of the moving direction of keeping body 255 when component 36 engages, in the front openings of the moving direction.That is, groove 58b exists In the case that handle 50 is located at first position or the second place, it is open towards position holding member 35,36.In example illustrated In, groove 58b is in lower opening.Therefore, keeping body 255 by moved downwards in handle main body 51 and with position holding member 35th, 36 is close, so that the 58 reception position holding member 35,36 of holding section of keeping body 255.At this time, position holding member 35,36 By the engaging with groove 58b, it is subject to the relative movement relative to groove 58b with the nonparallel direction of the length direction of groove 58b Limitation.On the other hand, groove 58b has constant cross sectional shape along each position of its length direction.Therefore, position maintaining part Part 35,36 can move in groove 58b along the length direction of groove 58b.That is, position holding member 35,36 with keeping body 255 In the state of engaging and limiting the swing of handle 50, the relative movement of the length direction along groove 58b is allowed to.

It should illustrate that position holding member 35,36 has enlarged diameter parts in the front end that can be located at groove 58b.It is another Aspect, the holding section 58 of keeping body 255,355 have limit flange 58c of the limitation enlarged diameter parts from the extraction of groove 58b.Cause This, in the example in the figures, position holding member 35,36 can only enter in groove 58b from opening portion 58ba.Moreover, in position In the state of holding member 35,36 is located in groove 58b, position holding member 35,36 is relative to keeping body 255,355 only along guarantor Holding the length direction (length direction of axle portion 51a) of body 255,355 can relatively move, in other words, to keeping body 255,355 The relative movement in length direction (length direction of axle portion 51a) nonparallel direction be restricted.

, also can be in keeping body 255 and first position holding member 35 for the perambulator 10 shown in Figure 23 and Figure 24 In the state of engaging, main body frame 12 is deformed, start jackknife action.As already mentioned above, it is held in first position in handle 50 Under state, two positions of position and first position holding member 35 of the main body frame 12 on the axis of oscillation sa of handle 50 connect It is connected to handle 50.Delimited moreover, first position holding member 35 is fixed on the first connecting rod 20 of axis of oscillation sa.Therefore, i.e., The main body frame 12 in jackknife action is set to deform, from distances of the axis of oscillation sa untill first position holding member 35 Do not change.That is, in the case where starting jackknife action in the state of keeping body 255 engages with first position holding member 35, the One position holding member 35 will not be moved relative to the keeping body 255 in handle main body 51.In addition, keeping body 255 is dynamic in folding By the active force from the second force application part 54 in work, will not be relatively moved relative to handle main body 51.

On the other hand, in the state of handle 50 is held in the second place, keeping body 55 by with second place maintaining part Part 36 engages and is connected to main body frame 12.Moreover, second place holding member 36 is not secured to first connecting rod 20 and second Either one in connecting rod 25, and it is affixed to handrail 19.It is adjoint in jackknife action such as from the comparison of Figure 22 and Figure 23 The deformation of the main body frame 12 in jackknife action, it is gradual from distances of the axis of oscillation sa untill second place holding member 36 It is elongated.Therefore, in the case where starting jackknife action in the state of keeping body 255 engages with second place holding member 36, the Length direction of the two position holding members 36 in jackknife action along handle main body 51 on the part of keeping body 255 is provided with Relatively moved relative to keeping body 255.At this time, keeping body 255, will not be opposite by the active force from the second force application part 54 Relatively moved in handle main body 51.Second place holding member 36 is along handle main body 51 towards from the separated sides of axis of oscillation sa To being moved relative to keeping body 255.Specifically, as shown in figure 24, opened from underlying in the groove 58b of keeping body 255 Oral area 58ba sides, are moved towards innermost portion 58bb above.

In the example in the figures, second place holding member 36 is as shown in Figure 24 with double dot dash line in arrival slot 58b After innermost portion 58bb, and then moved along handle main body 51 to from the separated directions of axis of oscillation sa.At this time, such as Figure 25 institutes Show, second place holding member 36 moves together with keeping body 255 relative to handle main body 51.Keeping body 255 at this time is opposite Implement in action active force of the confrontation from the second force application part 54 of handle main body 51.Therefore, in the jackknife action, the Two force application parts 54 exert a force keeping body 255 towards second place holding member 36.That is, the second force application part 54 is in the folding In folded action, keeping body 255 is continuingly acted on to maintain the fastening state of keeping body 255 and second place holding member 36.Should Explanation is given, second place holding member 36 is relative to the direction of the relative movement of keeping body 255 along keeping body 255 relative to hand The direction of the relative movement of handle main body 51.Therefore, it is possible to be relatively moved from second place holding member 36 relative to keeping body 255 Action be swimmingly switched to second place holding member 36 and keeping body 255 relatively moved relative to handle main body 51 it is dynamic Make.

Next, for second place holding member 36 with keeping body so as to relative movement mode engage second Example, illustrates with reference to Figure 26~Figure 28.For the second case shown in Figure 26 and Figure 28, difference is keeping body 355 Length and the length of holding section 58 are longer than the first case shown in Figure 19~Figure 25, other can use identical composition.

In the example shown in Figure 26~Figure 28, in the state that above-mentioned keeping body engages with said second position holding member The lower jackknife action for starting perambulator, when main body frame 12 is deformed into folded state, second place holding member 36 is initially in groove Innermost portion 58bb is reached in 58b, or starts baby in the state of above-mentioned keeping body engages with said second position holding member The jackknife action of car, even if main body frame 12 is deformed into folded state, second place holding member 36 is also less than up in groove 58b Innermost portion 58bb.Therefore, the folding of perambulator 10 is started in the state of keeping body 355 engages with first position holding member 35 The situation of action and the folding for starting perambulator 10 in the state of keeping body 355 engages with second place holding member 36 Either one in the case of action, keeping body 355 are not pressed by position holding member 35,36, and therefore, keeping body 355 is obstructed Cross the active force from the second force application part 54 and acted relative to handle main body 51.

In the example illustrated with reference to Figure 19~Figure 28, perambulator 10 from unfolded state to folded state that can be folded from With the main body frame 12 that can be deformed from unfolded state to folded state and between the first location and the second location can The mode of swing is connected to the handle 50 of main body frame 12.Handle 50 has 51 and of handle main body for being connected to main body frame 12 The keeping body 255,355 of the handle main body 51 is supported in a manner of it can be moved relative to handle main body 51.Main body frame 12 With engage with keeping body 255,355 and limit handle 50 from the first position holding member 35 of the swing of first position and with Keeping body 255,355 engages and limits second place holding member 36 of the handle 50 from the swing of the second place.Moreover, second Put holding member 36 with along length direction of the handle main body 51 on the part of keeping body 255,355 is provided with relative to holding The mode that body 255,355 can relatively move engages with keeping body 255,355.On the other hand, in unfolded state and folded state Between, main body frame 12 deforms, and main body frame 12 and the relative position of handle 50 change.At this time, main body frame 12 and hand are become The keeping body 255,355 and second place holding member 36 of the clamped position of handle 50 can relatively move, dynamic corresponding to expansion The deformation of work or the main body frame 12 in jackknife action.Therefore, even if from second place holding member 36 to the pendulum of handle 50 In the case that distance untill shaft line sa changes between unfolded state and folded state, also can side by keeping body 255, The 355 engaging limitation handle 50 with second place holding member 36 is swung relative to the free of main body frame 12, edge contraction baby Youngster's car 10.In other words, no matter handle 50 is located at where first position and the second place, can start to fold behaviour Make.For example, in the case of the monthly age of infant is less, perambulator is utilized in the side configuration handle 5 faced with infant 10 situation becomes more, in such period, can handle 50 is configured at the second place it is constant in the state of folded.Separately Outside, when the perambulator folded up 10 is unfolded, it is constant that handle 50 is configured at the second place.Therefore, it is possible to save adjustment hand The step of position of handle 50, improve the convenience of perambulator 10.In addition, the setting position on second place holding member 36 Restriction tails off, the free degree increase of the design of perambulator 10, can also realize the small-sized lightness of perambulator 10.And then keep Being fastened in jackknife action of body 255,355 and second place holding member 36, which can be formed, deeper to be engaged.Therefore, even in In jackknife action, the state for engaging keeping body 255,355 with second place holding member 36 can be also stably maintained at.

In addition, in the example shown in Figure 19~Figure 28, block in keeping body 255,355 with second place holding member 36 In the case of starting jackknife action in the state of conjunction, second place holding member 36 exists in jackknife action along handle main body 51 The length direction being provided with the part of keeping body 255,355 is relatively moved relative to keeping body 255,355.Therefore, though from Distance of the second place holding member 36 untill the axis of oscillation sa of handle 50 changes between unfolded state and folded state In the case of, become the keeping body 255,355 and second place holding member of the clamped position of main body frame 12 and handle 50 36 can also follow the deformation of the main body frame 12 in expansion action or jackknife action and more swimmingly relatively move.Thus, , can when starting the jackknife action of perambulator 10 in the state of keeping body 255,355 engages with second place holding member 36 Stablize and swimmingly folded.

And then in the example shown in Figure 19~Figure 28, in the second place, holding member 36 is relative to keeping body 255,355 During relative movement, length side of the keeping body 255,355 in handle main body 51 on the part of keeping body 255,355 is provided with To positioned at fixed position, in other words, keeping body 255,355 be not provided with keeping body 255,355 along handle main body 51 Length direction on part moves in handle main body 51.Therefore, keeping body 255,355 and second place holding member 36 Relative movement can stablize and swimmingly realize.Thus, the state engaged in keeping body 255,355 with second place holding member 36 During the jackknife action of lower beginning perambulator 10, it can stablize and swimmingly be folded.

In addition, in the example shown in Figure 19~Figure 25, in the shape that keeping body 255 engages with second place holding member 36 In the case of starting jackknife action under state, second place holding member 36 is being provided with keeping body 255 along handle main body 51 Length direction on part is relatively moved relative to keeping body 255, and second place holding member 36 stops relative to holding afterwards The relative movement of body 255, is moved together with keeping body 255 relative to handle main body 51.According to such example, guarantor can be shortened The length of body 255 is held, while reducing amount of movement of the keeping body 255 relative to handle main body 51.Thus, in keeping body 255 When starting the jackknife action of perambulator 10 in the state of engaging with second place holding member 36, it can stablize and swimmingly carry out Fold, while can realize the small-sized lightness of perambulator 10.

Particularly in the example shown in Figure 19~Figure 25, second place holding member 36 relative to keeping body 255 phase Direction to mobile direction along keeping body 255 relative to the relative movement of handle main body 51.Therefore, it is possible to more effectively contract The length of short keeping body 255, while reducing amount of movement of the keeping body 255 relative to handle main body 51.Thus, in keeping body 255 engage with second place holding member 36 in the state of when starting the jackknife action of perambulator 10, can stablize and swimmingly Folded, while can realize the small-sized lightness of perambulator 10.

Example according to Figure 26~Figure 28, in the state of keeping body 355 engages with second place holding member 36 In the case of starting jackknife action, during keeping body 355 is untill from unfolded state to folded state, exist in handle main body 51 The length direction on the part of keeping body 355 is provided with positioned at fixed position, in other words, will not set along handle main body 51 The length direction being equipped with the part of keeping body 355 moves in handle main body 51.On the other hand, in keeping body 355 and second In the case that position holding member 36 starts jackknife action in the state of engaging, second place holding member 36 is from unfolded state During untill folded state, continue the relative movement relative to keeping body 355.That is, it is dynamic folding according to such example In work, only second place holding member 36 is relatively moved relative to keeping body 355, can be by keeping body 355 relative to handle master It is constant that body 51 maintains static state.Therefore, start in the state of keeping body 355 engages with second place holding member 36 During the jackknife action of perambulator 10, it can stablize and swimmingly be folded.In addition, keeping body 355 is relative to handle main body 51 Amount of movement can be the specially engaging with first position holding member 35 and second place holding member 36 and depart from institute Amount necessary.Thereby, it is possible to effectively realize the small-sized lightness of perambulator 10.

It should illustrate that it is explained above some variations for above-mentioned embodiment, naturally it is also possible to suitably group Close multiple variations and apply.
