Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a torso guard provided in association with a seat of a baby carriage, and more particularly to a mounting structure to which the torso guard is detachable.

[0002]

2. Description of the Related Art In many cases, strollers are provided with a torso guard for connecting the front ends of a pair of handrails arranged on both sides of the seat. In particular, when the infant to be put on the stroller is small, it is recommended to provide a torso guard to protect the torso of the infant.

The trunk guard is usually removably attached to the handrail and is constructed so that it can be removed when an infant grows and grows larger. The detachable body guard is, for example, Japanese Patent Publication Sho 58
-32068 gazette. This special public Sho 58
In the body guard described in Japanese Patent Laid-Open No. 32068, a pin is used to attach the body guard to the handrail, and by inserting the pin so as to penetrate the body guard and the handrail, the attachment state of the body guard can be obtained. On the other hand, the body guard is configured to be removed from the handrail by pulling out the pin.

[0004]

However, in the case of the above-mentioned conventional body guard, the operation of pulling out the pin when removing this is relatively troublesome, and the operation of inserting the pin is also comparatively difficult when attaching this. It is troublesome.
However, if the torso guard that has been used up to now is to be removed according to the growth of the infant, even if the operation for it is troublesome, the removal and installation will not be so frequent, so there will be almost no problem. There is no.

On the other hand, when an infant is put on and off the seat of the baby carriage, it is easier to leave the torso guard removed. Therefore, the detachable structure of the torso guard is as described above. It may be used to remove when loading and unloading and then reattaching. In this case, it is particularly desirable that the trunk guard can be easily attached and detached.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a mounting structure for a torso guard of a baby carriage which is easy to mount and remove.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a mounting structure for a stroller guard of a baby carriage, which is mounted so as to connect between front ends of a pair of handrails arranged on both sides of a seat. In order to solve the above-mentioned technical problem, the following features are provided.

That is, according to the present invention, the front end of the handrail is provided with the projection having the engaging recess formed on the side surface thereof, while the trunk guard has the cylindrical end portion for detachably receiving the projection. Structured. A ring-shaped locking member surrounding the projection is provided in the end portion so as to be movable in a direction intersecting with the side surface of the projection. This ring-shaped locking device
It is configured to engage with the engaging recess at one end of its movement, and to escape from the engaging recess at the other end of its movement, and is biased by the elastic body so as to move to the one end. In addition, the ring-shaped locking device,
An operation part for moving the elastic body from the one end to the other end against the bias of the elastic body is provided so as to be exposed from the end of the trunk guard.

[0009]

According to the present invention, the operating portion exposed from the end portion of the trunk guard is operated to move the ring-shaped locking member against the urging force of the elastic body, whereby the engaging recess is formed. The body guard is ready to be removed from the handrail. On the other hand, if the projection is received in the end of the trunk guard and the ring-shaped locking member is engaged with the engaging recess while moving the ring-shaped locking member against the biasing force of the elastic body,
The attachment state of the trunk guard can be obtained.

As described above, the operation for attaching and detaching the body guard is simple, and the body guard can be attached and detached quickly. Therefore, it is possible to repeat this operation frequently without any problem. For example, by removing the torso guard, the front of the seat is opened and the infant can be easily put on and off. In the present invention, when the protrusion has a circular cross section and the engaging recess is formed so as to circulate around the peripheral surface of the protrusion, the end of the trunk guard is retained while the ring-shaped locking tool remains engaged with the engaging recess. Since the part can rotate around the protrusion, if the trunk guard is removed only at one end of the trunk guard as described above, the trunk on the other end can be centered. The front of the seat can be opened by rotating the guard. Since this state is sufficient to facilitate the loading and unloading of the infant, the labor for attaching and detaching the torso guard can be further simplified.

The above-described structure also functions to allow such a folding operation when the stroller is a folding type and the spacing between the pair of handrails is changed during the folding operation. To do. That is, in the stroller that performs the folding operation in this manner, the trunk guard is normally foldable at its center portion to allow the change in the spacing between the pair of handrails. In this case, however, the trunk guard is folded. In order to be possible, the end of the torso guard must be rotatable with respect to the handrail. According to this configuration,
Since the end of the torso guard is rotatable with respect to the handrail, the folding operation of the baby carriage is not hindered by the torso guard even with the torso guard attached.

Further, in the present invention, it is preferable that the protrusion is provided so as to selectively take a state in which it is projected and a state in which it is retracted from the handrail. With such a configuration, it is possible to avoid the inconvenience that the protrusion projects from the handrail in the state where the trunk guard is removed. That is, when the projection protrudes from the handrail, it may not only cause discomfort to the infant touching it, but also cause a problem of injury, but these problems occur when the torso guard is removed. It can be avoided by keeping the protrusions retracted.

Further, as described above, when the projection is selectively projected or retracted,
The second elastic body urges the projection to project toward the handrail, and an engaging member is provided to maintain the projection in a retracted state against the urging by the second elastic body. If it is left, it becomes possible to easily and swiftly make the protrusion project or project. That is, the projecting protrusion is retracted against the bias of the second elastic body and the engaging member is engaged, whereby the retracted state is maintained, while the engagement by the engaging member is released. The protrusion of the projection is automatically obtained by the biasing of the second elastic body.

FIG. 1 is a perspective view showing the appearance of the entire baby carriage to which a body guard mounting structure according to an embodiment of the present invention is applied. The baby carriage 1 shown here includes a seat 2, and a pair of handrails 3 and 4 are arranged on both sides of the seat 2. A body guard 5 is attached so as to connect between the front ends of the handrails 3 and 4.

The details of the mounting portion of the body guard 5 on the one handrail 3 are shown in FIG. 2 by a partially cutaway side view. FIG. 3 is a sectional view taken along the line III-III in FIG.
4 is a diagram corresponding to FIG. 2, showing a state different from that in FIG. 1, and FIG. 5 is a cross-sectional view taken along line VV in FIG. Further, FIG. 6 is a view corresponding to FIG. 2, showing the handrail 3 after the trunk guard 5 is removed. The trunk guard 5 itself and the handrails 3 and 4 have a symmetrical structure, and the mounting structure of the trunk guard 5 (not shown) on the other handrail 4 is the same as the mounting structure on the handrail 3 shown. Therefore, the following description will be made on the mounting portion of the body guard 5 to the handrail 3, and the description of the mounting portion to the other handrail 4 will be omitted.

A projection 6 is provided at the front end of the handrail 3. An engagement recess 7 is formed on the side surface of the protrusion 6. In this embodiment, the protrusion 6 has a circular cross section, and the engagement recess 7 is formed so as to circulate around the peripheral surface of the protrusion 6. Also,
The protrusion 6 is configured to selectively take a state in which it protrudes from the handrail 3 as shown in FIG. 2 and a state in which it retracts from the handrail 3 as shown in FIG. 6, for example. Is preferred. Therefore, the protrusion 6 is movably guided in the cylindrical portion 8 formed on the handrail 3, and the end of the protruding state is the flange 9 formed at the base of the protrusion 6 as shown in FIG. It is defined by engaging the end surface of the tubular portion 8. On the other hand, the end of the projection 6 in the retracted state is defined by abutting on the holding table 10 attached to the handrail 3, as shown in FIG.

As described above, when the projection 6 is configured to be in a projected state and a retracted state, it is more preferable that the projection 6 is elastic so as to project to the handrail 3. On the other hand, a hook-shaped engaging member 12 that engages with the above-mentioned flange 9 is provided in order to maintain the retracted state by being biased by the coil spring 11 as a body. The engagement member 12 is elastically deformable in order to allow engagement and release thereof. These coil springs 1
1 and the engaging member 12 are held by the holding table 10 described above.

On the other hand, the body guard 5 has a cylindrical end portion 13 for detachably receiving the projection 6. Within this end 13 a ring-shaped locking device 14 is arranged which surrounds the projection 6. The ring-shaped locking tool 14 is provided so as to be movable in a direction intersecting with the side surface of the projection 6, for example, in a direction orthogonal to this embodiment. In this way, the ring-shaped locking device 14 engages with the engagement recess 7 at one end of its movement as shown in FIGS. 2 and 3, and at the other end of its movement as shown in FIGS. As shown in FIG. 5, it is configured to escape from the engaging recess 7.

Further, the ring-shaped locking tool 14 is biased by a leaf spring 15 as an elastic body so as to move to the above-mentioned one end. The leaf spring 15 is arranged, for example, between the inner peripheral surface of the tubular end portion 13 and the ring-shaped locking tool 14. Further, in order to define the end of the movement of the ring-shaped locking tool 14 by the leaf spring 15, the ring-shaped locking tool 14 is formed with a locking piece 16 that engages with the inner peripheral surface of the cylindrical end portion 13. Has been done.

Further, the leaf spring 1 is attached to the ring-shaped locking tool 14.
An operation portion 17 for moving the one end from the other end against the bias of 5 is provided so as to be exposed from the end 13. In this embodiment, the operation unit 17
Is provided so as to project from the end portion 13, and the operation portion 17
The ring-shaped locking tool 14 can be moved by pushing. It should be noted that the operation portion 17 is located on the front side or the lower side of the torso guard 5 and is designed so as not to be inadvertently touched by an infant.

In such a structure, as shown in FIGS.
As shown in, to remove the trunk guard 5 from the state where it is attached to the handrails 3 and 4, the following operation is performed. That is, the operating portion 17 is pushed in to bring the ring-shaped locking tool 14 out of the engagement recess 7 as shown in FIGS. 4 and 5. In this state, if the end portion 13 is pulled up, the protrusion 6 can be pulled out from the end portion 13 and the end portion 13 and the handrail 3 can be separated from each other.

The above-described operation may be carried out on both handrails 3 and 4, or on one handrail, for example only handrail 3. When this operation is performed on both handrails 3 and 4, the torso guard 5 can be completely separated from the handrails 3 and 4. In this state, the baby may be loaded and unloaded, but it is generally preferable that the baby is brought into this state when the baby has grown and the trunk guard 5 is no longer needed.

In this way, the body guard 5 is attached to the handrails 3 and 4.
When completely separated from the protrusion 6, as shown in FIG.
Is preferably pressed. When the projection 6 is pushed in, the engaging member 12 is deformed by contact with the flange 9 in the middle thereof and finally engages with the flange 9. By this, despite the biasing by the coil spring 11,
The retracted state of the protrusion 6 is maintained.

On the contrary, in order to bring the projection 6 into the protruding state, a finger or the like may be inserted from below the handrail 3, the engaging member 12 may be deformed, and the engagement with the flange 9 may be released. Accordingly, the projection 6 is immediately returned to the projecting state by the action of the coil spring 11. In this way, in the state where the protrusion 6 is projected, as shown in FIGS.
1 is positioned while the body guard 5 is positioned with respect to the handrails 3 and 4 in a state in which the protrusion 6 is received in the end portion 13 while pushing in 7, the operating portion 17 is pushed in.
Through the handrails 3 and 4 as shown in FIG.
It can be attached again to.

As described above, the torso guard 5 is not completely separated from the handrails 3 and 4, but only one end thereof, for example, the end 13 is removed from the handrail 3 so that an infant can be loaded and unloaded. It is more efficient to do so. That is, since the protrusion 6 has a circular cross section and the engagement recess 7 is formed so as to circulate the circumferential surface of the protrusion 6, only the end 13 is removed from the handrail 3.
The torso guard 5 becomes rotatable with respect to the other handrail 4, and if the front of the seat 2 is opened according to this rotation, an infant can be easily put on and off.

From the above, when the convenience of loading and unloading infants is pursued exclusively and the complete separation from the handrails 3 and 4 is not required, the above-mentioned characteristic construction of the present invention has the body guard 5 It is applied only to one end 13 and one handrail 3, and the other end of the body guard 5 and the other handrail 4 may not be detachable, but may simply have a rotatable mounting structure. Can be said.
