Then, the moving portions 76 and 86 of the lock portions 71 and 81 open in the opening direction of the arrow Z.

Similarly, the convex portion 74 c of the lock portion 71 is fitted in the upper concave portion 103 of the right operation portion 101, and the convex portion 84 c of the lock portion 81 is fitted in the lower concave portion 104. Thus, by operating the right operation portion 101, the convex portion 74c moves from the flat portion 103a of the upper concave portion 103 to the inclined portion 103b, and the convex portion 84c moves from the flat portion 104a of the lower concave portion 104 to the inclined portion 104b. Then, the moving portions 74 and 84 of the lock portions 71 and 81 open in the opening direction of the arrow Z. In this way, the protrusion 53b of the insertion portion 53 engages with the protrusions 74c and 84c of the moving portions 76 and 84, and the protrusion 53b of the insertion portion 57 and the protrusions 74c and 84c of the moving portions 76 and 84. The engagement with can be released.

As described above, since the connector 5 uses the attraction of the magnet, it is possible to lock the engaging members 51 and 55 only by penetrating the through holes 64a and 65a of the engaged member 60. Furthermore, since the repulsion of the magnets is used, it is not necessary to pull out the engaging members 51 and 55, and the lock can be released only by operating the operation units 91 and 101. Thereby, the connector 5 of the present embodiment can be easily locked and unlocked.

Moreover, since the locking of the engaging members 51 and 55 and the engaged member 60 is ensured by using the lock portion 70 in combination with the attraction and repulsion of the magnet, the connection of the connecting device 5 can be strengthened. it can. Therefore, it is optimal as the connector 5 of the stroller 1 which requires safety.

As a result, the engaging member 55A and the engaged member 60A are brought into the engaged state by the attraction of the magnet and the engagement between the insertion portion 57A and the right interposition portion 120A. In this case, as shown in FIG. 12B, the convex portion 123A of the right interposition portion 120A is located on the first flat portion 114A of the guide portion 113A.

When the engagement of the left engagement member 51A, the right engagement member 55A, and the engaged member 60A is released, the state shown in FIGS. 11B and 13 is obtained. That is, the operation unit 110A is pressed in the pressing direction (downward) indicated by the arrow Y. As a result, the third magnet 98A of the operation section 110A faces the first magnet 54A of the insertion section 53A and the first magnet 58A of the insertion section 57A. The third magnet 98A has an S pole on the side facing the first magnet 54A and an N pole on the side facing the first magnet 58A, and thus repels the first magnets 54A, 58A.

Further, when the operating portion 110A is pressed, as shown in FIG. 13B, the convex portions 123A and 128A (the convex portion 128A is not shown) move from the first flat portion 114A of the guide portion 113A to the inclined portion 115A. It passes and moves to the 2nd flat part 116A. As a result, as shown in FIGS. 13B and 13C, the distance between the pair of side wall portions 122A of the right intervening portion 120A and the distance between the pair of side wall portions 127A of the intervening portion 125A are increased, and the right intervening portion is formed. The protrusion 122aA of the portion 120A and the slit portion 57aA of the insertion portion 57A are disengaged, the engagement member 55A can be disengaged from the engaged member 60A, and the protrusion 127aA of the left intervening portion 125A and the insertion portion 53A. The left engagement member 51A and the engagement member 55A can be disengaged from the engaged member 60A by disengaging the slit portion 53aA.

In this way, the connector 5A of the present embodiment can operate the left engagement member 51A and the right engagement member 55A with one operation portion 110A. That is, the engagement between the left engagement member 51A and the right engagement member 55A can be released at the same time only by pressing the operation portion 110A, so that the shoulder belt 45 and the shoulder belt 44 can be released at the same time.

<Third Embodiment>

That is, the operation main body 102B of the right operation unit 101B includes a first operation main body 102aB extending in the left-right direction and a second operation protruding upward from one end of the first operation main body 102aB (the left end on the paper surface of FIG. 15). The main body 102bB is included. The other end of the first operation body 102aB (the right end on the paper surface of FIG. 15) is exposed from the housing 62. A through hole 106B extending in the left-right direction is provided in the first operation body portion 102aB at a position overlapping the stopper 62a in the vertical direction. The second operation body portion 102bB has an upper recess 103B and a lower recess 104B, a second magnet 109, and a third magnet 108. The inclined portion 103bB of the upper concave portion 103B and the inclined portion 104bB of the lower concave portion 104B are located on the inner side (the side facing the second operation body portion 92bB).

By operating the first operation body portions 92aB and 102aB, the engaged member 60B is displaced from the state shown in FIG. 15(a) to the state shown in FIG. 15(b), and the second operation body portion 92bB is moved outward (see FIG. 15, the second operation portion 102bB also moves outward (left side of the paper surface of FIG. 15), and the positions of the second operation main body portions 92bB and 102bB are separated. Thereby, the convex portions 74c and 86c of the lock portion 70 move along the inclined portions 103bB and 93bB of the upper concave portions 103B and 93B, and the convex portions 76c and 84c of the lock portion 70 move to the inclined portions 94bB of the lower concave portions 94B and 104B. Move along 104bB. The subsequent operation is the same as that of the first embodiment.

The second magnet 109 is provided on the outer side in the operating direction (the side not facing the second operating body 92bB), and the third magnet 108 is on the inner side in the operating direction (facing the second operating body 92bB). Side). The second magnet 109 faces the through hole 65a (FIG. 16A) when the first operation main body 102aB is not operated, and the third magnet 108 is pressed when the first operation main body 102aB is pressed. It faces the through hole 65a (FIG. 16B). The second magnet 109 is magnetized in a direction (engagement direction) from the front surface to the back surface of the right operation portion 101B. Specifically, the second magnet 109 has an S pole on the front side and an N pole on the back side.

The third magnet 108 has a polarity opposite to that of the second magnet 109, and the front side is the N pole and the back side is the S pole.

(About the operation of the connector)
Prior to the description of the operation of the connector 5B of the third embodiment, the operation of the connector 5 of the first embodiment due to the attraction or repulsion of the magnet will be described with reference to FIG.

As shown in FIG. 17A, in the first magnets 54, 58 of the engaging members 51, 55 of the first embodiment, the side facing the engaged member 60 is the N pole. Since the second magnets 99 and 109 facing the through holes 64a and 65a of the engaged member 60 are S poles, the first magnets 54 and 58 and the second magnets 99 and 109 are attracted, and FIG. As shown, the engaging members 51 and 55 and the engaged member 60 engage with each other. In this case, the third magnets 98, 108 located outside the second magnets 99, 109 have N poles on the through holes 64a, 65a side (the front side of the fixed portion 61), so that the engaging members 51, 55 have the same configuration. It has the same pole as the first magnets 54 and 58. Therefore, when engaging the engaging members 51 and 55 with the engaged member 60, the left engaging member 51 is brought from the left side of the engaged member 60, and the right engagement is performed from the right side of the engaged member 60. When bringing the mating member 55, as shown by the arrow in FIG. 17A, the first magnets 54, 58 and the third magnets 98, 108 repel each other, and the engaging members 51, 55 are engaged. In some cases, the mating member 60 cannot be quickly engaged.

When releasing the engagement between the engaging members 51, 55 and the engaged member 60, the operating portions 91, 101 (Fig. 4) are operated to move the engaged members as shown in Fig. 17(c). The third magnets 98, 108 of the coupling member 60 are moved to the through holes 64a, 65a side (the inner side of the engaged member 60 shown by the arrow). As a result, the N poles of the third magnets 98, 108 and the N poles of the first magnets 54, 58 face each other and repel each other, so that the engagement between the engaging members 51, 55 and the engaged member 60 is released. .. In the engaging members 51, 55, the first magnets 54, 58 and the second magnets 99, 109 attracting the magnets move inward, so that the left engaging member 51 moves inward as shown in FIG. 17C. It jumps off (in the vicinity of the center of the paper) and comes off, and the right engagement member 55 also jumps inward (close to the center of the paper) and comes off. Therefore, when the engagement members 51, 55 and the engaged member 60 are released from each other, the engagement members 51, 55 remain in the abdomen of the infant riding on the seat 20 (FIG. 1), and I can't take it down smoothly.

On the other hand, in the present embodiment, as shown in FIG. 16A, the first magnets 54, 58 of the engaging members 51B, 55B have the N pole on the side facing the engaged member 60B. Since the second magnets 99 and 109 facing the through holes 64a and 65a of the engaged member 60B are south poles, the first magnets 54 and 58 and the second magnets 99 and 109 are attracted, and FIG. As shown, the engaging members 51B and 55B and the engaged member 60B are engaged with each other. In this case, the third magnets 98, 108 have the same poles as the first magnets 54, 58 of the engaging members 51B, 55B because the through holes 64a, 65a side (front side of the fixed portion 61) have N poles. The third magnets 98 and 108 are located inside the second magnets 99 and 109. Therefore, even when the right engaging member 55B is brought from the right side of the engaged member 60B and the left engaging member 51B is brought from the left side of the engaged member 60B, the third magnet 98, Since 108 does not hinder the attraction of the first magnets 54, 58 and the second magnets 99, 109, the engaging members 51B, 55B can be quickly engaged with the engaged member 60B.

When releasing the engagement between the engaging members 51B, 55B and the engaged member 60B, the operating portions 91B, 101B (Fig. 15) are operated to engage the engaged members as shown in Fig. 16(c). The third magnets 98, 108 of the combination member 60B are moved to the through holes 64a, 65a side. As a result, the N poles of the third magnets 98, 108 and the N poles of the first magnets 54, 58 face each other and repel each other, so that the engagement members 51B, 55B and the engaged member 60B are disengaged. .. In this case, the second magnets 99 and 109 and the third magnets 98 and 108 move outward as indicated by the arrows by operating the operation units 91B and 101B (FIG. 15). In the engaging members 51B and 55B, since the first magnets 54 and 58 and the second magnets 99 and 109 that attract each other move outward, as shown in FIG. 16C, the left engaging member 51B moves outward ( The right engaging member 55B also flies to the outside (right side of the paper) and comes off. Therefore, when the engagement members 51B, 55B and the engaged member 60B are released from each other, the engagement members 51, 55 fly to both sides of the baby on the seat 20 (FIG. 1), so that the baby can be smoothly moved. You can take it down.

Next, with reference to FIG. 18, in the connector 5Ba including the engaged member 60B of the present embodiment and the engaging members 51 and 55 of the first embodiment, engage the engaged member 60B. The operation of the engagement members 51, 55 when the engagement of the members 51, 55 is released will be described in detail.

The connector 5Ba is changed from the state of FIG. 18B to the state of FIG. 18C by pressing the operation portions 91B and 101B. That is, since the first magnets 54 and 58 of the engaging members 51 and 55 and the third magnets 108 and 98 of the engaged member 60B face each other, the same N pole faces each other. On the other hand, the repulsive force in the direction indicated by the arrow P1 (the direction in which the operation portions 91B and 101B move) acts. At the same time, along with the movement of the operation portions 91B and 101B, the attraction force of the engaging members 51 and 55 in the direction indicated by the arrow P2 (the direction in which the first magnets 54 and 58 attract the second magnets 99 and 109). Works. Therefore, the direction in which the engaging members 51, 55 project from the through holes 64a, 65a is the direction indicated by the arrow P3 (the direction extending obliquely upward toward the outside).

As a result, as shown by the broken line circles in FIG. 18D, the protrusions 53b and 57b of the engaging members 51 and 55 are caught in the wall portions 64c and 65c of the through holes 64a and 65a, and the engaged members 60B. The engagement between the engagement members 51 and 55 cannot be released smoothly. Therefore, in the engaging members 51B and 55B of the present embodiment, as shown in FIG. 19, the protruding portions 53b and 57b of the engaging members 51B and 55B are caught in the wall portions 64c and 65c of the through holes 64a and 65a. In order to prevent it, it has the following configuration.

(About engaging member)
The engaging members 51B and 55B have a movement restricting portion on the outer side in the operating direction of the operating portions 91B and 101B. The movement restricting portion is a portion that restricts the insertion portions 53B and 57B from moving outward in the operation direction within the through holes 64a and 65a while the insertion portions 53B and 57B are located inside the through holes 64a and 65a. Is. Hereinafter, the shape of the movement restricting portion will be described in detail.

19(a) and 19(b) are views showing the right engagement member 55B. With reference to FIG. 19, the insertion portion 57B of the right engagement member 55B is continuous with the first protrusion 57cB protruding from the step 56b and the first protrusion 57cB, and is recessed inward from the first protrusion 57cB. The slit part 57aB and the 2nd protrusion part 57bB which continues from the slit part 57aB are included. A rib 57dB that connects the first protruding portion 57cB and the second protruding portion 57bB is provided in a part of the slit portion 57aB. Specifically, the rib 57dB extends in the vertical direction and fills the slit portion 57aB. The rib 57dB is provided on the outer side in the operation direction of the operation unit 101B, in other words, in the direction in which the engaging members 51B and 55B project (the arrow direction in FIG. 18A). The rib 57dB is provided at a position that matches the gap S between the first moving portions 74a and 84a of the lock portion 70 when the right engaging member 55B and the engaged member 60B are engaged with each other. The rib 57 dB as described above serves as a movement restricting portion.

Since the rib 57dB is provided, the rib 57dB and the wall portion 64c of the through hole 64a (FIG. 18D) come into contact with each other, and the right engaging member 55B does not fly obliquely upward toward the outside, and the through hole does not fly. It jumps out above 64a. This prevents the second protrusion 57b and the wall portion 64c of the through hole 65a from being caught as described in FIG. 18D, so that the engagement between the right engaging member 55B and the engaged member 60B is smoothed. It can be canceled. The right engagement member 55B has been described above, but the left engagement member 51B has the same shape as the right engagement member 55B.

(Regarding a modification of the movement restriction unit)
Another modification of the movement restricting unit will be described with reference to FIG. The movement restricting portion may be provided on the engaging members 51C and 55C and the engaged member 60C.

A rib 57dC protruding outward from the step portion 56b is provided on the step portion 56b of the engaging member 55C. The rib 57dC is provided in a circular shape so as to surround the outer periphery of the insertion portion 57. The rib 57dC is provided at a distance of several millimeters from the outer circumference of the insertion portion 57, but may be provided in the region of the step portion 56b.

A groove 65bC recessed inward from the right recess 65 is provided on the right recess 65 of the engaged member 60C. The width of the groove portion 65bC is larger than the width of the rib 57dC. The groove portion 65bC is provided at a position corresponding to the rib 57dC when the engaging member 55C is engaged with the engaged member 60C, and is provided in a circular shape so as to surround the through hole 65a. The rib 57dC and the groove portion 65bC serve as a movement restricting portion. The movement restricting portion of the present embodiment has an uneven shape. By providing the movement restricting portion (the rib 57dC and the groove portion 65bC), when the engagement member 55C and the engaged member 60C are disengaged, the engagement member 55C is restricted from moving obliquely upward. The protruding portion 53b of the engaging member 55C is not caught on the wall portion 64c. Although not shown, the left engagement member 51C has the same shape as the right engagement member 55C, and the left recess 64 (FIG. 14) has the same shape as the right recess 65.

The movement restricting portion does not have to be circular, and may be provided only in a part as shown in FIG. In that case, the rib 57dD and the groove portion 65bD are provided in the direction in which the engaging member 55D pops out (the direction of the arrow in FIG. 18A). The longitudinal dimension of the groove portion 65bD may be larger than the width dimension of the rib 57dC, or may be substantially the same dimension. The left engagement member 51D has the same shape as the right engagement member 55D, and the left recess 64 (FIG. 14) has the same shape as the right recess 65.

The movement restricting portion is formed of the ribs 57dC and 57dD of the engaging members 51C, 51D, 55C and 55D and the groove portions 65bC and 65bD of the engaged members 60C and 60D. The reverse shape in which the groove portions are provided in 51D, 55C, and 55D and the ribs are provided in the engaged member may be used.

With reference to FIG. 22, another modification of the movement restricting unit will be described. The movement restricting portion may be formed by devising the shape of the insertion portion 57E of the engaging members 51E and 55E.

The insertion portion 57E of the engagement member 55E is continuous with the first protruding portion 57cE protruding from the step portion 56b and the first protruding portion 57cE, and is connected with the groove portion 57aE recessed more inward than the first protruding portion 57cE and the groove portion 57aE. The second protrusion 57bE is included. As particularly shown in FIG. 22C, the lateral width dimension L2 of the first protruding portion 57cE is larger than the lateral width dimension L3 of the second protruding portion 57bE. That is, the diameter L1 of the through hole 65a is set to be slightly smaller than the lateral width dimension L2 of the first projecting portion 57cE, whereas it is set to be considerably smaller than the second projecting portion 57bE.

As a result, when the engagement member 55E and the engaged member 60E are disengaged, even if the right engagement member 55E is inclined, the second protrusion 57bE is caught in the wall portion 65c of the through hole 65a. It gets harder. As a result, even if the engaging member 55E flies in the direction indicated by the arrow P3 (the direction that extends obliquely upward toward the outside), the second projecting portion 57bE of the engaging member 55E comes to the wall portion 65c of the through hole 65a. It is hard to be caught, and the engaging member 55E can be smoothly skipped and removed. The left engagement member 51E has the same shape as the right engagement member 55E.

<Embodiment 4>
23 to 27, a configuration example of the connector 5F used in the baby carriage 1 according to the fourth embodiment will be described in detail. The configuration of the baby carriage 1 is similar to that of the first embodiment, but the configuration of the connector 5F is different. Only the differences from the connector 5 shown in the first embodiment will be described in detail.

The main difference between the connector 5 of the first embodiment and the connector 5F of the present embodiment is the shape of the engaged member 60F. That is, in the engaged member 60 of the first embodiment, the magnets 98, 99, 108, and 109 are slid and displaced by pressing the operation portions 91 and 101 themselves, whereas the engaged members 60 of the present embodiment are different. In the engaged member 60B, when the operation button 141F is operated, the first and second operation units 150F and 160F rotate and move, and the positions of the magnets 98, 99, 108 and 109 are displaced.

(About engaged members)
The engaged member 60F of the present embodiment will be described with reference to FIGS. 24 and 25. The engaged member 60F includes a fixed portion 61F, an operation portion 140F, and a lock portion 70F. In FIG. 24, the direction indicated by arrow A is called the front side (front), and the direction opposite to arrow A is called the back side (rear). Further, in FIG. 25, the direction indicated by the arrow C is referred to as upward, and the direction opposite to the arrow C is referred to as downward.

In particular, as shown in FIG. 24, the fixed portion 61F is not provided with the left recessed portion 64 and the right recessed portion 65 as in the first embodiment, but is provided with the through holes 64a and 65a directly on the housing 62. There is. Further, an opening 62bF, which is an opening for an operation button 141F described later, is provided at a substantially central portion of the housing 62.

The operation unit 140F includes an operation button 141F and an operation unit 142F that is displaced by operating the operation button 141F. One operation button 141F is provided and movable in the front-back direction. Here, the operation button is a portion that is moved by directly touching it with a finger, and includes not only a portion that is moved by pressing but also a portion that is pulled or pinched.

As shown in FIG. 24, the operation button 141F includes a pressing part 143F provided on the front side, an inclined part 144F provided on the back side, a vertical part 146F parallel to the pressing part 143F, and the operation button 141F fixed to the fixing part 61F. And a hooking portion 145F. The pressing portion 143F is a flat plane, and by pressing the pressing portion 143F, the operation button 141F itself slides backward. The inclined portion 144F has a shape that inclines downward from the front side to the back side. The inclined portion 144F contacts an operation portion 142F described later. As a result, by operating the operation button 141F, the operation unit 142F can be displaced. This operation will be described later. The hook portion 145F has a convex shape protruding outward from the side of the operation button 141F. The hooking portion 145F is hooked on a slit-shaped hooked portion 62cF provided in the housing 62 so as to be movable in the front-rear direction.

The operating portion 142F has a first operating portion 150F facing the through hole 64a of the fixed portion 61F and a second operating portion 160F facing the through hole 65a of the fixed portion 61F. The first operation unit 150F and the second operation unit 160F are provided symmetrically, for example. As shown in FIG. 25, the first operating unit 150F and the second operating unit 160F are connected by a rotary shaft 165F. The first operation unit 150F and the second operation unit 160F can be displaced by operating the operation button 141F.

With particular reference to FIG. 25, the first operating unit 150F has a first operating body 151F, a second magnet 99, and a third magnet 98. The first motion main body 151F rotates the upper end 154F with which the convex portion 86cF of the second lock portion 81F abuts, the recess 153F into which the convex portion 76cF of the first lock portion 71F is fitted, and the first motion main body portion 151F. It has a shaft portion 152F capable of being held by the fixing portion 61F as much as possible, and a spring support portion 156F. The upper edge 154F is an inclined surface that inclines so as to descend outward.

When the first operation body 151F rotates clockwise around the shaft 152F, the inclination angle of the upper edge 154F increases, and the position of the recess 153F moves downward. In addition, the second magnet 99 is arranged outside the third magnet 98, as in the left operation unit 91B of the third embodiment. The second magnet 99 and the third magnet 98 are arranged substantially inclining in consideration of the fact that the first operating unit 150F rotates about the shaft portion 152F. In this description, the engaged member 60F is viewed from the back side, but in the state viewed from the front side, the first operation body 151F rotates counterclockwise.

The second operation unit 160F has substantially the same shape as the first operation unit 150F.
