Therefore, the "front-rear direction d1" is the direction corresponding to the lower left and upper right of the connecting paper in FIG. In addition, as long as there is no special instruction, the so-called "front" refers to the side facing the infants and young children riding, and the lower left side of the paper surface in FIG. On the other hand, the “vertical direction d2” is a direction orthogonal to the front-rear direction d1 and orthogonal to the ground plane of the stroller 1. Therefore, when the ground plane of the stroller 1 is a horizontal plane, the so-called "up and down direction d2" refers to the vertical direction. In addition, the "width direction (lateral direction) d3" is a direction orthogonal to either of the "front-rear direction d1" and the "vertical direction d2". Furthermore, "right" and "left" also mean "right" and "left" in the width direction d3 based on the infant and the child riding in the stroller 1, respectively.

In the stroller 1 shown in FIGS. 1 and 2, a body frame 10 having a pair of front legs 11, a pair of rear legs 12 and a pair of armrests 13 is provided, and a handle 20 is detachably attached to the body frame 10. Each front foot 11 is equipped with a front wheel 2 and each rear foot 12 is equipped with a rear wheel 3.

The upper end portion of the front leg 11 is a front portion that is rotatably connected to the armrest 13 disposed on the corresponding side (left or right side). Similarly, the upper part of the rear foot 12 is The front portion of the armrest 13 disposed on the corresponding side (left or right side) is rotatably connected.

In addition, the rear part of the armrest 13 is connected to the middle part of the rear leg 12 disposed on the corresponding side (left or right side) through the link member 14 and the rotation bracket 15.

The handle 20 is attached to the body frame 10 constructed as above. The handle 20 is configured to be swingable between the back pressing position shown in FIG. 1 and the opposite pressing position shown in FIG. 2.

The stroller 1 having the overall configuration as described above is as follows, and can be folded by rotating the pair of constituent members to each other. First, when the stroller 1 in the unfolded state as shown in FIG. 2 is folded, the handle 20 arranged at the rear position is temporarily raised upward and rearward, and then pushed downward. Along with the movement of the handle 20, the link member 14 and the rotating bracket 15 are separated from the rear foot 12, and the rotating bracket 15 rotates the rear foot 12 clockwise in FIG. In addition, with this operation, the armrest 13 rotates the link member 14 clockwise in FIG. 3.

As shown in FIG. 3, in this way, in a side view, the handle 20 and the front foot 11 are arranged slightly parallel, and the arrangement position of the handle 20 is lowered, so that the stroller 1 can be folded. Furthermore, to unfold the stroller 1 from the folded state, it is only necessary to follow the steps opposite to the folding operation described above.

Having said that, the stroller 1 of the present embodiment is designed to improve transportation efficiency, and is configured to be folded by removing the handle 20 from the frame body 10, and the handle 20 can be installed at the place of use with a single key operation Frame body 10. Hereinafter, the mounting structure of the frame body 10 and the handle 20 will be described with reference to FIGS. 4 to 11. 4 is an enlarged perspective view showing the mounting structure of the frame body 10 and the handle 20. As shown in FIG. 4, the mounting pin 16 protrudes outward in the width direction d3 from the rotation bracket 15, and the mounting member 30 of the handle 20 is mounted on the mounting pin 16.

The handle 20 is shown enlarged in FIG. 5. As shown in FIG. 5, the handle 20 is formed by inserting mounts 30 at both ends of the U-shaped handle frame 21. As an element constituting the handle frame 21, a pair of left and right front guides 22 are provided, and the upper ends of the pair of front guides 22 are connected to each other by an operation part 23. The operation unit 23 is a part that allows the user to operate with the hand in order to travel the stroller 1 in the unfolded state. In the example shown in the figure, the Between the upper ends of the front guide portion 22, a curved operation portion 23 is arranged, and the handle frame 21 is formed substantially in a U shape.

One attachment 30 is attached to the end of each front guide 22. The mounting member 30 is a component for mounting the handle frame 21 to the frame body 10 with a single key operation. In FIGS. 6 to 8, the state where the mounting pin 16 is inserted into the mounting member 30 is enlarged. As shown in FIGS. 6 to 8, the end portion of the front guide portion 22 is embedded with a housing 31 as an element constituting the mounting member 30. The cover 31 is shaped like a cylinder, and accommodates and protects the end of the front guide 22 and other components constituting the mounting member 30. In addition, the cover 31 is formed with a through hole 31a through which the mounting pin 16 passes.

The embedded component 32 is fixed in the casing 31, and the fixing plate 33 is supported by the embedded component 32. The fitting component 32 is a plate-shaped component that is provided in a space outside the front guide portion 22 in the width direction d3 in the space inside the housing 31 and hangs downward from the upper edge of the housing 31. The fitting part 32 is fitted to the upper edge of the cover 31, and a receiving portion 32a that is open downward is provided at the lower end of the hanging portion.

The fixing plate 33 is inserted into the housing portion 32a from below. The accommodating portion 32a is partitioned by the front wall 32b and the rear wall 32c facing upward in the front-rear direction; the pair of side walls 32d and 32e facing the upper surface in the width direction d3; and the front wall 32b, the rear wall 32c and the pair The upper wall 32f above the side walls 32d, 32e. The walls 32b-32f partitioning the accommodating portion 32a surround the fixing plate 33 accommodated in the accommodating portion 32a, and limit the moving range of the fixing plate 33. In this way, the fixing plate 33 is supported by the fitting 32 so as to be movable in the vertical direction d2. In other words, the fixing plate 33 is supported by the handle frame 21 so as to be movable in the up-down direction d2 through the cover 31 and the embedded component 32.

The fixing plate 33 is a component for locking the mounting pin 16. As shown in FIGS. 6 to 8, the fixing plate 33 is a plate-shaped component formed with an insertion hole 34 into which the mounting pin 16 is inserted. In particular, in the present embodiment, a through hole 24 is also formed in the front guide 22 of the handle frame 21, and the mounting pin 16 is both the through hole 24 of the front guide 22 and the insertion hole 34 of the fixing plate 33. The through hole 24 of the front guide portion 22 and the insertion hole 34 of the fixing plate 33 have a long axis along the width direction d3.

In FIG. 9, the mounting pin 16 is enlarged. As shown in Figure 9, as an axial structure The mounting pin 16 of the tool has a long-side axis X along the width direction d3, and the spin bracket 15 protrudes outward in the width direction d3. The mounting pin 16 is formed with a groove 16c extending in the circumferential direction d4 of the mounting pin 16, and is divided into a head 16a and a base 16b through the groove 16c. In the present embodiment, the groove 16c is ring-shaped with its both ends connected.

As shown in FIG. 9, the base portion 16 b of the mounting pin 16 is attached to the rotation bracket 15, and the head portion 16 a located outside the base portion 16 b in the width direction d3 is the front end that is the farthest from the rotation bracket 15. The head 16a is formed to have a thinner tip as it goes outward in the width direction d3.

3。即，從圖10所示之方向觀看時，鎖固用區域34a是小於安裝銷16之頭部16a，且解除用區域34b是大於安裝銷16之頭部16a。 In FIG. 10, the fixing plate 33 is enlarged. As shown in FIG. 10, the insertion hole 34 of the fixing plate 33 includes a locking region 34a and a releasing region 34b that partially overlap each other. The locking area 34a and the unlocking area 34b have a circular outline when viewed from the direction shown in FIG. 10, in other words, when viewed from the axis direction X of the mounting pin 16. In particular, the diameter of the locking area 34a

1 is smaller than the diameter of the head 16a of the mounting pin 16

3 (refer to FIG. 8), and the diameter of the release area 34b

2 is larger than the diameter of the head 16a of the mounting pin 16

3. That is, when viewed from the direction shown in FIG. 10, the locking area 34 a is smaller than the head 16 a of the mounting pin 16, and the releasing area 34 b is larger than the head 16 a of the mounting pin 16.

In the example shown in FIG. 10, the locking area 34 a is located below the releasing area 34 b in the up-down direction d2, and the fixing plate 33 is movable in the up-down direction d2 in the accommodating portion 32 a of the fixing plate 33. According to this form, when the fixing plate 33 is relatively upward, the locking area 34a faces the head 16a of the mounting pin 16 and the through hole 24 of the front guide 22; when the fixing plate 33 is relatively downward, the release area 34b faces the head portion 16a of the mounting pin 16 and the through hole 24 of the front guide portion 22.

In FIG. 11, the state where the head 16 a of the mounting pin 16 faces the release area 34 b of the insertion hole 34 is shown. As shown in FIG. 11, when the head 16a of the mounting pin 16 faces the release area 34b of the insertion hole 34, since the diameter of the head 16a is smaller than the release area 34b, the release area 34b can be passed through Axis direction X. In this way, the position where the head 16 a of the mounting pin 16 can pass through the fixing area 33 of the releasing area 34 b of the insertion hole 34 is referred to as the releasing position P2.

On the other hand, as shown in FIG. 8, when the head 16a of the mounting pin 16 faces the insertion

When entering the locking area 34a of the hole 34, the diameter of the head portion 16a is larger than that of the locking area 34a, so the locking area 34a cannot pass through the axis direction X. In this way, the position where the head 16a of the mounting pin 16 cannot pass through the fixing plate 33 of the locking area 34a of the insertion hole 34 is called the locking position P1. At the locking position P1, the fixing plate 33 is formed to partially enter the groove 16c of the mounting pin 16 inserted into the locking area 34a.

In addition, a spring 35 as a potential energy imparting member is installed between the lower end of the cover 31 and the fixing plate 33. The spring 35 presses the fixing plate 33 upward in the accommodating portion 32a of the fitting part 32, in other words, it imparts potential energy to the fixing plate 33 from the release position P2 toward the lock position P1. In addition, the fixing plate 33 is pressed into the accommodating portion 32a by the spring 35 to prevent the fixing plate 33 from being detached from the accommodating portion 32a. In the illustrated example, the projecting piece 33a projects downward from the other part of the fixing plate 33, and the spring 35 is wound around the projecting piece 33a.

Next, the operation of attaching the handle 20 constructed as above to the frame body 10 will also be described with reference to FIG. 12. FIG. 12 is a front view showing one of the processes of attaching the handle 20 to the frame body 10.

First, from the state shown in FIG. 4, the mounting pin 16 of the frame body 10 is gradually inserted into the mounting member 30 of the handle 20. As shown in FIG. 12, the inserted mounting pin 16 passes through the through hole 24 of the handle frame 21 and then advances toward the insertion hole 34 of the fixing plate 33. As described above, since the fixing plate 33 is pressed toward the locking position P1 by the spring 35, the head 16a of the mounting pin 16 faces the locking area 34a and is ready to enter the locking area 34a. However, since the diameter of the head portion 16a is larger than the locking area 34a, it cannot contact the fixing plate 33 through the locking area 34a.

Here, the head portion 16a of the mounting pin 16 is formed to have a thinner tip end toward the outside in the width direction d3. Moreover, in the observation from the width direction, even when the fixing plate 33 is located at the locking position P1, the center of the head 16a is still located in the locking area 34a. Therefore, if the head 16a of the mounting pin 16 is further gradually pressed into the fixing plate 33, the fixing plate 33 will be pressed downward according to the shape of the head 16a. Thereafter, if the head 16a of the mounting pin 16 is further pressed into the fixing plate 33, the fixing plate 33 will be pressed down to the release position P2 shown in FIG. 11, and the release area 34b of the insertion hole 34 will be in contact with the mounting pin 16. Head 16a facing surface.

If the head 16a is further pressed into the fixing plate 33, the head 16a will pass through the release area 34b. As described above, due to the potential energy given to the fixing plate 33 by the spring 35, when the head 16a passes through the releasing area 34b, the elastic force of the spring 35 is released, and the fixing plate 33 is pushed back to the locking position P1. Thus, as shown in FIGS. 6 to 8, the fixing plate 33 will enter the groove 16 c of the mounting pin 16, and the mounting pin 16 is restricted.

To remove the handle 20 from the frame body 10, use a special tool that is not easily removed by the user to push the fixing plate 33 up to the release position P2, and then pull out the mounting pin 16 from the insertion hole 34.

As described above, according to the present embodiment, the frame body 10 includes the shaft-shaped member 16; and the handle 20 is detachably attached to the frame body 10 through the shaft-shaped member 16, and the handle 20 includes the handle frame 21; fixed The plate 33 is a fixing plate 33 formed with an insertion hole 34 into which the shaft-shaped member 16 is inserted, and can be locked between the locking position P1 of the shaft-shaped member 16 restricted to be inserted into the insertion hole 34 and the unlocked shaft-shaped member 16 The movement between the restricted release position P2 is supported by the handle frame 21; and the potential energy member 35 is imparted to the potential energy of the fixing plate 33 toward the locking position P1. According to this form, by folding the handle 20 with the handle 20 removed from the frame body 10, the size at the time of folding can be reduced. On the other hand, when assembling, after inserting the shaft-shaped member 16 of the frame body 10 into the insertion hole 34 of the fixing plate 33 of the handle 20, as long as the fixing plate 33 is moved to the locking position P1 by the energizing potential member 35, The handle 20 is assembled to the frame body 10, so the practicability is also high.

Furthermore, according to the present embodiment, the handle frame 21 is formed with a through-hole 24 through which the shaft-shaped member 16 penetrates, and the through-hole 24 of the handle frame 21 is the case where the fixing plate 33 is located at either of the locking position P1 and the releasing position P2 Below, all face the insertion hole 34 of the fixing plate 33 at least partially. By passing the shaft-shaped member 16 through the through-hole 24 of the handle frame 21, the shaft-shaped member 16 can also be received by the handle frame 21 with high rigidity. As a result, it helps to stably assemble the handle 20 to the frame body 10.

Furthermore, according to the present embodiment, the shaft-shaped member 16 is formed with a groove 16c extending in the circumferential direction d4 of the shaft-shaped member 16, and the fixing plate 33 is at the locking position P1 At this time, it is formed to partially enter the groove 16c of the shaft-shaped member 16 inserted into the insertion hole 34. According to this configuration, since the fixing plate 33 partially enters the groove 16c of the shaft-shaped member 16 at the locking position P1, it is difficult for the shaft-shaped member 16 to deviate in the axial direction X of the shaft-shaped member 16. Thereby, the fixing plate 33 can restrain the shaft-shaped member 16 more stably, and as a result, it helps to assemble the handle 20 to the frame body 10 more stably. Further, by extending the groove 16c into a circular ring shape, the handle 20 can be smoothly shaken to the frame body 10.

Furthermore, according to the present embodiment, the shaft-shaped member 16 includes the head 16a and the base 16b that are divided by the groove 16c. The base portion 16b has a fixed diameter (thickness), while the head portion 16a is formed toward the front end to become thinner and thinner. In this case, even if the potential energy of the fixing plate 33 is applied to the locking position P1 by applying the potential energy member 35 in advance, during combination, as the head 16a of the mounting pin 16 is pressed into the fixing plate 33, The fixing plate 33 gradually moves toward the release position P2. Therefore, the mounting pin 16 can be easily inserted into the insertion hole 34. As a result, the handle 20 can be easily assembled to the frame body 10, and the usability is further improved.

In addition, according to the present embodiment, the insertion hole 34 of the fixing plate 33 includes a locking area 34a. When the fixing plate 33 is located at the locking position P1, the locking area 34a overlaps the shaft-shaped member 16 and the shaft The axial direction X of the member 16; and the release area 34b, when the fixing plate 33 is located at the release position P2, the release area 34b overlaps the axial direction X of the shaft member 16 and the shaft member 16, and the lock area 34a and the release area 34b partially overlap each other. When viewed from the axial direction X of the shaft member 16, the lock area 34a is smaller than the head portion 16a of the shaft member 16, and the release area 34b is larger than the shaft member The head 16a of 16. In this case, the fixing plate 33 can be switched between the state where the shaft-shaped member 16 is restricted and the state where the shaft-shaped member 16 is freed by the difference in size between the locking region 34a and the releasing region 34b. Therefore, the fixing plate 33 can be realized with a simple structure, and therefore it is highly practical.

Furthermore, in the above-mentioned embodiment, each of the left and right shaft-shaped members 16 and the left and right mounting members 30 may have the same structure or a different structure. 13 and 14 show examples in which the left and right shaft members 16 have different structures. in In the examples shown in FIGS. 13 and 14, the mounting pin 16 on the left side has a polygonal shape, more specifically a pentagonal shape, in a cross section orthogonal to its axial direction X, and the mounting pin 16 on the right side is orthogonal to The cross section in the axial direction X has a polygonal shape that is different from the axial member 16 on the left side, more specifically, a quadrangular shape. That is, the outer contours 16m of the left and right mounting pins 16 in the cross section orthogonal to the axial direction X are staggered without overlapping each other.

In this case, it is possible to avoid assembling the handle 20 upside down on the frame body 10. That is, even if the mounting member 30 to be mounted on the left front guide 22, for example, is assembled to the right mounting pin 16, the fixing plate 33 to the insertion hole 34 of the left mounting member 30 is not applicable to the shape of the right mounting pin 16, Cannot be assembled upside down.

In addition, the means for preventing the handle 20 from being assembled upside down on the frame body 10 is not limited to the examples shown in FIGS. 13 and 14, and various means can be considered. Other examples include a scheme in which the size of the left and right mounting pins 16 are made different, or a position in which the positions of the left and right mounting pins 16 are asymmetric.

Furthermore, in addition to such physical means, by visually preventing the handle 20 from being assembled upside down on the frame body 10, it is also conceivable to provide, for example, a mark for identifying left and right. For example, different colors may be applied between the left and right mounting pins 16 and the left and right housings 31 to identify the left and right, or different marks may be added between the left and right rotating brackets 15 and the left and right housings 31 To identify left and right solutions. In particular, as an example in which different marks are added to the left and right, an example in which a number or "left and right" characters are expressed by engraving or printing is given.
