The present invention relates to a mechanism for folding the handrails installed in the baby carriage by interlocking with the opening and closing operation of the baby carriage.

Seats for infants in the stroller is equipped with a railing is stable.

Such handrails are often arranged in a protruding state in the deployed state of the baby carriage.

When the baby carriage is folded in the arrangement state thereof, it is preferable to be accommodated in the occupied space of the whole baby carriage, but in most cases, the railings protrude forward even when the baby carriage is folded, for example.

In the folded state of the stroller, it is also possible to add a mechanism for interlocking with the folded motion of the stroller to accommodate it in the occupied space of the folded stroller. The main purpose of the present invention is to provide a mechanism that can be folded in accordance with the opening and closing operation of the baby carriage in a simple configuration.

In other words, the present invention is to simply implement the folding mechanism of the handrail by advantageously using the operation of the olfactory always provided in the stroller.

When this is explained in detail based on drawing, the grip part 1 which carries out a hydraulic pressure by the person who carries a baby carriage is installed in the upper end part of a pair of push bar 2.

In addition, between the upper ends of the pair of push bar (2) is connected to the push bar connection (4) that can be bent in the direction of the arrow (3).

The push rod 2 is curved at each lower end thereof, but its straight portion is configured to guide the slide of the slide pivot connecting member 5.

The upper end of the embossed portion 10 is sandwiched between the slide pivot connecting member 5 via the bearing piece 6.

The left and right corners 10 are connected as full width connecting rods 11 for reinforcement.

The full width connecting rod 11 can be bent in the direction of the arrow 12.

The footrest (not shown) is mounted using the full-width connecting rod 11 so that the foot of the child in the stroller can be mounted.

The front wheel 13 of a rotating material is provided in the lower end part of the embossed base 10.

In the middle part of the longitudinal direction of the full width 10, the back 14 is connected.

More specifically, the connecting plate 15 is fixedly mounted at the upper end of the olfactory element 14.

Since the axial pin 16 penetrating the end of the connecting plate 15 is mounted on the full width 10, the rear angle 14 is pivotally connected to the full width 10.

At the lower end of the rear leg 14, the rear wheel 17 is rotatably installed.

The left and right olfactory legs 14 are connected as olfactory connecting rods 18 for reinforcement.

The olfactory connecting rod 18 is bent in the direction of the arrow 19.

One end portion of the support angle 20 is pivotally connected via the bearing pin 21 in the middle portion of the longitudinal direction of the back leg 14.

The other end of the support angle 20 is pivotally connected to the lower end of the pressure bar 2 via the bearing pin 22.

The front and rear connecting rods 24 are pivotally connected to each other by a middle pin 23 of the support angle 20.

The olfactory connecting rod 24 extends in the front and rear directions, and is connected to the full width 10 by the bearing pin 25 at a portion that intersects the full width 10.

The front and rear connecting rods 24 have portions extending forward from the full width 10 again.

The center connecting rod 26 is connected between the upper and lower right and left connecting rods 24. Its central transverse connecting rod 26 can be bent in the direction of the arrow (27). A handrail 28 protruding rearward from the full width 10 is provided. The handrail 28 is motivated with respect to the full width 10 by means of a bearing pin 29.

Next, the respective parts will be described in more detail. Both ends of the full width connecting rods 11 are pivotally rotatably rotated on the slider 31 via the pin 30, and the slider 31 is slidable over the full width 10. It is explained. A rod ring 32 is connected between the slider 31 and the front end of the front and rear connecting rods 24. The worm 34 is pivotally connected to the embossed portion 10 via the bearing pin 33. The worm 34 and the full width connecting rods 11 are located at the tip of the worm 34 and by the pins 35 positioned at intervals of a predetermined distance from each front end of the full width connecting rods 11.

The worm 34 and the full width connecting rod 11 are pivotally connected by the axial pin 35 positioned at the tip of the worm 34 and spaced a predetermined distance from each end of the full width connecting rod 11. do.

In such a configuration, when the front end of the front and rear connecting rod 24 is rotated upward, the slider 31 slides upward against the full width 10 via the rod ring 32.

In response, both ends of the full width connecting rod 11 are pulled upward. As a result, the full width connecting rod 11 held by the worm 34 via the bearing pin 35 is bent in the direction of the arrow 12. This allows the operation of the pair of full widths 10 to be close to each other. Furthermore, the reverse operation is also achieved by interposing the rod linking 32 and the slider 31 in the same shape.

4 is a perspective view showing a connection mechanism between the phase of the central transverse reverse rod 26 and the olfactory connecting rod 18. FIG. Between the central lateral connecting rod 26 and the olfactory connecting rod 18, a pair of interlocking links 37 intersected in a "x" shape and etched by mutual pins 36 are connected. A connection point is preferred between the interlocking link 37, the central transverse connecting rod 26, and the olfactory connecting rod 18, such as universal twist. In the folded operation of the stroller, as can be clearly seen in the following description, the central lateral connecting rod 26 and the olfactory connecting rod 18 move close to each other.

Therefore, the linkage linkage 37 is projected so that the bending in the direction of the arrow 27 of the center connecting rod 26 and the bending of the furnace in the direction of the arrow 19 of the olfactory connecting rod 18 are interlocked with each other.

On the contrary, in the unfolding operation of the baby carriage, the central lateral connecting rod 26 and the olfactory connecting rod 18 move in a state of being separated from each other.

Therefore, since the interlocking link 37 pulls the central horizontal connecting rod 26 and the olfactory connecting rod 18 to each other, the central horizontal connecting rod 26 and the olfactory connecting rod 18 extend in a straight state.

5 is a perspective view showing another modification of the coupling mechanism of FIG. In this example, a pair of interlocking links 38 extending in a "V" shape, which are almost parallel to each other, are used in place of the operative linkage 37 crossed in the "X" shape.

The connection portion of the interlocking link 38, the central horizontal connecting rod 26 and the olfactory connecting rod 18 is preferably connected like a universal twist.

Since the linkage link 38 here functions like the linkage link linkage 37 of FIG. 4, the description in FIG. 4 can be used almost as is, and the description related to the linkage link 38 is omitted. do.

FIG. 7 is a sectional view taken along line 7-7 of FIG.

8 is a cross-sectional view taken along line 8-8 of FIG.

FIG. 9 is a sectional view taken along line 9-9 of FIG.

The connection plate 15 accommodates the upper end of the olfactory diode 14 to fix the olfactory diode 14 by the fixing pin 39. In the vicinity of the upper end of the olfactory element 14, the guide hole 40 is formed by extending in the longitudinal direction of the olfactory element 14. The lock pin 41 is inserted into the guide hole 40 thereof. The lock pin 41 is movable in the guide hole 40. The vicinity of the upper end of FIG. 6 of the support angle 20 is polymerized with a part of the guide hole 40 and a cutout 42 (shown in FIG. 12) coinciding with a part of the guide hole 40 is formed therein. . The lock pin 41 is formed by the compression spring 43 as shown in FIG.

Its eccentric cam 44 is fixed to the operation knob 46 is installed.

The state shown in Figs. 6 to 9 is when the lock is made. In other words, the lock pin 41 is inserted into the cutout 42, and the support angle 20 is maintained in a state in which the rear angle 14 is aligned so that the support angle 20 does not rotate with respect to the rear angle 14. This state is realized when the short diameter portion of the eccentric cam 14 is in contact with the projection 45. In this state, the compression spring 43 presses the lock pin 41 into the notch 42 to maintain the lock state thereof. Referring to the operation for releasing the locked state thereof, Fig. 10 shows a substantial portion in Fig. 6 and the state immediately after the lock is released.

FIG. 11 shows a substantial portion in FIG. 9 and a significant state in FIG. In releasing the lock, the eccentric cam 44 may be rotated only 180 degrees in any direction via the operation knob 46. Thus, the states shown in FIGS. 10 and 11 are realized. Here, the state where the long diameter portion of the eccentric cam 44 is in contact with the projection 45 is realized. As a result, the lock pin 41 moves in the direction of escape from the cutout 42 against the elasticity of the compression spring 43.

Furthermore, in order to remove the unstable test that is reversed from the eccentric cam 44, which is pressed downward through the lock pin 41 by the compression spring 43, as the starting point of the eccentric cam 44, The neck portion is provided with a concave inlet portion 47 that receives the projection 45. (Shown in Figures 9 and 11)

Next, the operation directly related to the support angle 20 in the operation from the release of the lock to the folding of the baby carriage as described above will be described. FIG. 12 shows a substantial portion in FIG. Displays the state during opening and closing.

In the above-described FIG. 10, the lock pin 41 has escaped from the cutout 42, so that the support angle 20 is rotated in the direction of the arrow 48 around the bearing pin 21. As shown in FIG.

As the support angle 20 rotates in the direction of the arrow 48 in this way, the projection 48 that is in contact with the long diameter portion of the eccentric cam 44 thus far moves in the direction away from the eccentric cam 44.

For example, as shown in FIG. 12, when the protrusion 45 is completely disengaged from the eccentric cam 44, the lock pin 41 is extended to the lower end of the guide hole 40 by the action of the compression spring 43. Move.

When the baby carriage is in a deployed state in a folded state, the support angle 20 is rotated in the direction of the arrow 49 around the axis pin 21 and the protrusion 45 is close to the eccentric cam 44. . At this time, the guide portion 50 formed on one side of the cut-out portion 42 of the support ingot 20 is accompanied in the direction of the arrow 49 of the support angle 20 to press the lock pin 41 slightly upward. .

At the same time, the projection 45 is in a state of being directly connected to the eccentric cam 44. Only the projection 45 is kept in contact with the eccentric cam 44, and the rotation of the support angle 20 in the direction of the arrow 49 causes the eccentric cam 44 to be forcibly shown in FIG. I'm going to meet up.

This is because the lock pin 41, which is the eccentric shaft of the eccentric cam 44, is strongly pushed downward by the locking spring 43, and the lock pin 41 is trying to stay at the lower end of the guide slot 40. On the other hand, the projection 45 tries to approach the lock pin 41 by the rotation of the support angle 20 in the direction of the arrow 49. This is because the eccentric cam 44 must be rotated so that its shorter diameter portion is in contact with the projection 45 in order to satisfy the relative positional relationship between the two.

Therefore, when the support angle 20 is completely aligned with the olfactory edge 14, it will be in the state shown in FIG. Therefore, the locked state is automatically realized.

FIG. 13 is a side view showing the mounting state of the handrail 28 on the full width 10 as a feature of the present invention.

14 is a side view showing the left and right sides of the handrail 28 in the folded state of the baby carriage.

Referring to FIG. 13, the handrail 28 is rotatably connected to the full width 10 by an axis pin 29. The horizontal vertical position in FIG. 13 of this handrail 28 is protected and supported by the structure demonstrated below.

On the other hand, for the olfactory 14, the engaging plate 52 is formed at the lower end of the engaging wall 51 is engaged projection 52 is engaged. Accordingly, in the state in which the olfactory element 14 is deployed with respect to the full width 10, that is, in the unfolded state of the baby carriage, the engaging protrusion 52 engages with the lower end of the engaging wall 51, so that the railing 28 may move the bearing pin 29. It becomes the state which can be rotated downward by the center.

In addition, the end side wall 15a formed in the connecting plate 15 moves in the direction of the arrow 15b, and a state of contacting the engaging wall 51 at the beginning of the rotation of the olfactory edge 14 is realized, whereby the handrail ( 28 may be forcibly rotated downward.

At least at the end of the rotation to the lower side of the handrail 28, the handrail 28 is polymerized with the full width 10 by its gravity. When the baby carriage is deployed in the folded state, it automatically changes from the state of FIG. 14 to the state of FIG. The balustrades 28 are formed with a furrow 53 constituting a part of all the cam devices. The connecting plate 15 is formed with a cam 54 paired with the follower 53. Accordingly, when the back 14 is rotated as the center of the bearing pin 16 with respect to the full width 10, the cam surface 54 contacts the flow 53 and presses the flow 53 upward. .

As a result, the handrail 28 rotates upward with respect to the axis pin 29. Thus, when the handrail 28 approaches the final position of its rotation, the engagement protrusion 52 engages with the engagement wall 51 and realizes the left hand of the handrail 29 again as shown in FIG. At this time, the cam surface 54 is in a state of being connected to the furrow 53, whereby the horizontal posture of the handrail 28 is firmly protected and supported. Returning to FIGS. 1 to 3 again, there is shown a back support rod 55 for holding the back of the hammock (not shown) for the infant.

The upper end phase of the pair of backrest retaining rods 55 is connected by a bent back connecting rod 56. In addition, the left part of the hammock is mounted on the front and rear connecting rods 24 and the central transverse connecting rods 26 using their members. The lower end of the backrest retaining rod 55 is connected to the raising adjustment mechanism 57 attached to the pressing bar 2, whereby the raising state thereof is adjustable.

15 shows the upper end of the push rod 2, and the folded state of the baby carriage is locked. When the baby carriage is in the folded state, the slide pivot connecting member 5 slides above the push rod 2 to reach its upper end. Therefore, when the slide pivoting member 5 is locked in its position, the folded state of the baby carriage is locked. For this locking, an engaging piece 59 is attached to the rear wall 58 of the gripping portion 1. The engagement piece 59 is made of a material having moderate elasticity. The engaging projection 61 is formed on the rear wall 60 of the slide pivot connecting member 5. dental

And when passing through the inclined surface 62, the engaging piece 59 is automatically engaged with the engaging projection 61. When the lock is released, the engagement piece 59 may be forcibly deformed to the rear. Next, in the opening / closing operation and operation of the stroller, the support angle 20 is in the deployed state of the stroller in a locked state as the lock mechanism including the lock pin 41 in alignment with the smell 14. It is.

In order to move from the unfolded state to the folded state as described above, first, as described in FIGS. 6 to 11, the operation knob 46 is rotated 180 degrees to release the lock, and then the gripper 1 is held to hold the entire stroller. When lifted up as if floating from the ground, the support angle 20 is rotated in the direction of the arrow 48 (Fig. 10).

Next, as the front wheel 13 floats in the state in which the rear wheel 17 is in contact with the ground, the whole stroller is raised to the rear and the gripper 1 is pressed downward as it is. When the pressing force to the lower part of the holding part 1 is performed through the operation part 63 installed in the center of the push rod connecting rod 4, the point which the bending of the push rod connecting rod 4 to the arrow 3 direction at the time of arrow is advantageous is advantageous. Occurs. While the operation is in progress, the push rod 2 is also supported in a downward position so that the load and the slide pivot connecting member 5 simultaneously slide upward on the push rod 2.

In response to this, the front and rear edge bar 24 is rotated with its front end facing upward, and the slider 31 slides upward over the full width 10. In response thereto, the full width connecting rod 11 is bent in the direction of the arrow 12. In response to the bending of the full width connecting rod 11, the pair of full widths 10 are close to each other.

In addition, at the same time, a pair of push rods 2 are close to each other, or a pair of olfactory diodes 14 are close to each other, or a close to the full width 10 of the olfactory legs 14. As a result, the olfactory connecting rod 18 and the central lateral connecting rod 26 are in close proximity and are bent in the direction of arrows 19 and 27, respectively. In addition, the handrail 28 is connected to the corner 10 by being released from the engagement wall 51 and the engagement protrusion 52 to be in a conductive state.

Finally, as shown in FIG. 3, the full width 10 is in a state substantially parallel to the push bar 2, and the rear angle 14 is also in a state substantially parallel to the push bar 2.

Then, the left and right members are brought into close proximity to each other and thus folded state is obtained, which is locked as the lock mechanism shown in FIG.

Since the two front wheels 13 and the two rear wheels 17 are held at substantially the same height in the state of FIG. 3, the baby carriage can stand on its own in a folded state. In the folded state, the engagement with respect to the engaging projection 61 of the engaging piece 59 is first released. Next, the whole baby carriage is floated to the air with the operation unit 63. In response to this, the weight of the baby carriage moves and the support angle 20 rotates around the bearing pin 22 at the lower end of the pressure bar 2. At the same time, the slide pivot connecting member 5 slides downward on the pressure bar 2. Accordingly, the front and rear connecting rods 24 rotate as if they are almost horizontal.

In addition, the full width connecting rods 11 are left and right extended in response thereto. A pair of ems 10 are isolated from each other. In addition, at about the same time, the olfactory bulb 14 rotates as if it deviates from the full shell 10. In response, the olfactory connecting rod 18 and the central lateral connecting rod 26 interlock and extend left and right as an action of the interlocking link 37 (or 38). As such an operation, the pair of push rods 2, the pair of olfactory elements 14, and the pair of front and rear connecting rods 24 each move as if they extend in the width direction. The operation from FIG. 12 to FIG. 6 proceeds to become a lock.

In addition, the handrail 28 is in a horizontal state, and its state is maintained by the engaging projection 52. In this way, the expanded state of the baby carriage is realized, and the automatic lock becomes in the unfolded state thereof.

FIG. 16 is a perspective view in a developed state in another example of a baby carriage in an embodiment of the present invention.

17 is a right side view of the unfolded state, and FIG. 18 is a right side view of the folded state.

In the basic structure of the baby carriage shown here, first, the push rod 2 and the push rod connecting rod 4 are composed of integral materials. In this regard, the backrest support rod 55 and the backrest connecting rod 56 are composed of an integral material. The full width connecting rod 11 is configured by an integral rod. Likewise, the olfactory connecting rod 18 is also constituted by an integral rod.

Therefore, there is no slider 31, the rod ring 32 and the worm 34, etc., but the center connecting rod 26 is arranged before and after the connecting rod 24 before and after, respectively, and constitutes an integral rod. Again the scaffold 64 is mounted below the emc 10 and the handrail 28 is also shown in FIGS. 16-18, with only the results of its operation being shown. The railing 28 thereof also employs the mechanism shown in Figs. 13 and 14, and can be folded in response to the opening and closing operation of the baby carriage.

As described above, according to the present invention, the railing is advantageously operated in response to the opening and closing operation of the baby carriage, and in the deployed state of the baby carriage, it has a horizontal posture protruding from the front, and in the folded state, the railing has a soft compact posture and the motion of the railing. Since the sense of smell is realized only with a slightly modified state, a folding mechanism for a handrail having a simple configuration is realized, and it is practical to use because of its convenience and stability.
