Description

[Detailed description of the invention] [Industrial application field] This invention consists of a combination of a pair of handrails provided on a baby carriage and a body guard attached to connect the front ends of these handrails. The present invention relates to a handrail guard for a baby carriage, and in particular to the structure of a connecting portion between each handrail and a body guard.

[Prior Art] A baby carriage equipped with a handrail guard consisting of a pair of handrails located on both sides of a seat and a body guard attached to connect the front ends of these handrails is known, for example, as disclosed in Japanese Patent Publication No. 58. -Described in Publication No. 32068.

In this prior art, a chair-shaped seat is disclosed,
A pair of handrails are located on both sides of such a seat, and these handrails are fixedly provided to the body of the baby carriage.

On the other hand, the torso guard may become unnecessary when the infant in the seat grows up.
Since this can get in the way when loading and unloading infants from the seat, it is attached removably to the handrail.

In particular, as a structure for removably attaching the body guard to the handrail, this conventional technology has a structure in which the end of the body guard is received in a recess formed at the front end of the handrail, and the pin is attached to the handrail and the body. The present invention proposes a structure for advantageously filling the recess at the front end of the handrail that is left when the body guard is removed, assuming a structure in which the guard is inserted through both sides. More specifically, a hollow fitting body having an opening formed in a side face facing a certain direction is used, and this fitting body is fitted into a recess formed in the front end of the handrail in two different orientations. That is, when attaching the torso guard to the handrail, the end of the torso guard is received in the opening of the fitting body, and the torso guard is attached to the handrail by inserting the pin, while the torso guard is removed. Sometimes, the pin is pulled out, the body guard is removed, the fitting body is pulled out from the recess of the handrail, it is rotated by a predetermined angle, and the opening of the recess of the handrail is oriented so that it is closed by the side wall of the fitting body, and the fitting body is removed again. Fit into the recess. The pin is then reinserted, thereby fixing the mating body in that orientation. In this way, when the trunk guard is removed, the opening of the recess formed in the front end of the handrail can be closed by the fitting.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, not only does the attachment and removal of the body guard to the handrail always involve operations such as removing and inserting pins, but also the state in which the body guard is removed is required. If the mating body is left as it is, operations such as removing the mating body, changing the orientation, and refitting the mating body are required. Therefore, there was a problem that the above-mentioned work was relatively troublesome.

Therefore, this invention aims to provide a handrail guard for a baby carriage that allows for easy installation and removal of the body guard from the handrail, as well as automatic processing after the body guard is removed. .

[Means for solving the problem] This invention consists of two
Consisting of a pair of handrails and a body guard attached to connect the front ends of the handrails,
In the handrail guard for a baby carriage, the above-mentioned technical problem is solved as follows.

That is, the handrail guard of this baby carriage includes: a guide wall that is formed at each front end of the pair of handrails and defines a cavity having an opening at one end; and a guide wall that is positioned within the cavity. a slide member that is slidably held by a slide member and forms a lid for closing the opening at one end thereof; when the lid of the slide member assumes a position that closes the opening, a portion of the slide member stop means for defining the end of the sliding movement of the sliding member so that the sliding member does not protrude any further from the cavity by engaging a portion of the guide wall; spring means for biasing the slide member to slide in a direction to take the opening closing position; An insertion member inserted into the cavity from the opening; and a locking member provided on the insertion member side and elastically biased in a protruding direction in order to maintain the state in which the insertion member is inserted into the cavity. The present invention is characterized by comprising: a mating member; and a removable engaging means formed of an engaging hole provided on the guide wall side and receiving the engaging member.

[Function] In the handrail guard for a baby carriage according to this invention, when the body guard is attached to the handrail, the insertion members formed at each end of the body guard are inserted into the insertion members formed at each front end of the handrail. It is inserted into the empty space through the opening. Note that before such insertion, the opening is closed by the lid formed on the slide member, so to insert the insertion member into the cavity, the lid must be moved from the opening to the cavity. It is performed while displacing the body inward. The state in which the insertion member is inserted into the cavity is maintained by the engagement means.

On the other hand, when removing the body guard from the handrail,
First, the action of the engagement means that maintains the insertion member inserted into the cavity is released. Accordingly, the sliding member, under the action of the spring means,
As the insertion member is pushed out of the cavity, a lid formed on the slide member is positioned to close the opening.

[Effects of the invention] According to this invention, when attaching and removing the trunk guard from the handrail, operations such as removing the pin and reinserting it are not required as in the prior art described above. become. Further, even when the body guard is left in a detached state, there is no need to remove the fitted body, change its direction, and fit it again as in the prior art described above.

That is, in this invention, when attaching the trunk guard to the handrail, it is sufficient to simply insert the insertion member formed in the trunk guard into the cavity through the opening formed in the front end of the handrail. When the insertion member is inserted into the cavity in this manner, the engagement member elastically biased in the protruding direction automatically engages with the engagement hole.

In addition, when removing the body guard, all you have to do is release the engagement action by the engagement means.
Due to the action of the slide member biased by the spring means, the body guard is immediately separated from the handrail, and the opening of the handrail is automatically closed by a lid formed on the slide member. The state will be as follows. Therefore, even if, for example, both hands are occupied and it is not possible to apply force to pull out the torso guard in order to perform an operation to release the engagement state by the engagement means, The trunk guard can be easily removed. Also, after removing the torso guard,
There is no need to perform any process to close the handrail opening.

Also, according to this invention, there is no need for relatively small separable parts such as pins used in the prior art, so problems such as loss of such parts cannot occur.

[Description of Embodiment] FIG. 1 is a top view showing a handrail guard for a baby carriage, which is an embodiment of this invention. That is, the first
The figure shows a pair of handrails 1 and 2 located on both sides of the seat of the baby carriage, and a body guard 3 attached to connect the front ends of these handrails 1 and 2. Only the handrail guard 4, consisting of a laminate, is shown alone. The structure for attaching one end 5 of the trunk guard 3 to the front end 6 of one handrail 1 is substantially the same as the structure for attaching the other end 7 of the trunk guard 3 to the front end 8 of the other handrail 2. The same is true. Therefore, the structure for attaching one end 5 of the trunk guard 3 to the front end 6 of the handrail 1 will be described below with reference to FIGS. 2 to 4.

FIG. 2 shows the state after one end 5 of the trunk guard 3 is attached to the front end 6 of one handrail 1.
Illustrated in partial cross-section. FIG. 3 shows a partially sectional view of the trunk guard 3 before it is attached to the handrail 1. FIG. 4 shows one end 5 of the trunk guard 3 in a top view.

The front end 6 of the handrail 1 is formed with a guide wall 11 defining a cavity 10 having an opening 9 at one end. In this embodiment, the guide wall 11 has a generally cylindrical shape.

In the cavity 10, a slide member 12, for example a rod or a column, is arranged so as to be slidable in its longitudinal direction by a guide wall 11. A lid 13 for closing the opening 9 described above is formed at one end of the slide member 12. The lid 13 forms a spring receiving surface 14 extending in the radial direction at one end of the slide member 12. Further, the other end of the slide member 12 is provided with an outward flange 15 formed by, for example, fitting a ring-shaped member. On the other hand, the aforementioned guide wall 11 is provided with an inward flange 16 that can engage with the outward flange 15 .

The above-described outward flange 15 and inward flange 16 constitute a stopper means.
This stopper means prevents the sliding movement of the sliding member 12 from protruding any further from the cavity 10 when the lid 13 of the sliding member 12 takes the position of closing the opening 9, as shown in FIG. This is to define the termination. That is, in this state, the outward flange 15 engages with the inward flange 16, and the slide member 12
This defines the end of the sliding motion.

Further, as shown in FIG. 3, as a spring means for urging the slide member 12 to slide in the direction in which the lid 13 takes the position where the opening 9 is closed, a coil-shaped compression spring 17 is used, for example.
2, and is disposed between the spring receiving surface 14 and the inward flange 16.

On the other hand, an insertion member 18 is formed at one end 5 of the trunk guard 3 to be inserted into the cavity 10 through the opening 9. Although the cross-sectional shapes of the insert member 18 and the cavity 10 are arbitrary, in this embodiment, the insert member 18
has a cross-sectional shape that correlates to the cross-sectional shape of the cavity 10.

In order to maintain the insert member 18 inserted within the cavity 10, releasable engagement means are provided. The engagement means is provided on the insertion member 18 side and includes an engagement member 19 that is elastically biased in a protruding direction.
and an engagement hole 20 provided on the guide wall 11 side and receiving the engagement member 19.

More specifically, the engagement hole 20 is configured as a hole that penetrates the guide wall 11, and is located on the lower surface side of the handrail 1 in consideration of safety. Further, a concave portion 21 is formed on the lower surface of the peripheral edge of the engagement hole 20 in a tapered shape and widens downward.

On the other hand, the engagement member 19 includes an engagement pin 22 that is held movably in the vertical direction, and a spring 23 that urges the engagement pin 22 in a direction to project downward. Furthermore, it is preferable that the tip of the engagement pin 22 in the protruding direction be chamfered, for example, to form a spherical surface.

As described above, the structure for attaching the other end 7 of the body guard 3 to the front end 8 of the other handrail 2 is the structure for attaching the other end 7 of the body guard 3 to the front end 8 of the other handrail 2. Since the mounting structure is substantially the same as that of No. 5, the explanation will be omitted.

Next, operations for attaching the trunk guard 3 to the handrails 1 and 2 and operations for removing it from the handrails 1 and 2 will be explained. It should be noted that such an operation will also be explained with reference to FIGS. 2 to 4, so that it will be mainly related to one handrail 1 and one end 5 of the trunk guard 3.

First, when attaching the body guard 3 to the handrails 1 and 2, as shown in FIG. The opening 9 of the formed cavity 10 is aligned with the opening 9. Then, the body guard 3 may be pushed in in the direction shown by the arrow 24 so that the insertion member 18 is inserted into the space 10. Accordingly, the end surface of the insertion member 18 is aligned with the slide member 12.
The sliding member 12 slides against the elasticity of the compression spring 17, and the lid 13 is displaced from the opening 9 toward the inside of the cavity 10.
During such insertion, the tip of the engagement pin 11 comes into contact with a part of the edge of the guide wall 11, but if the body guard 3 is pushed in the direction of arrow 24, the engagement pin 22 Due to the chamfer formed on the tip of the engagement pin 22, the engagement pin 22 automatically becomes non-protruding. And, as shown in Figure 2,
At the end of insertion of the insertion member 18 into the cavity 10, the engagement pin 22 is in a protruding state according to the elasticity of the spring 23 and automatically fits into the engagement hole 20. This ensures that the insertion member 18 remains inserted into the cavity 10 despite the action of the compression spring 17, so that the body guard 3 can move between the pair of handrails 1 and 2. The attached state is maintained such that the front ends 6 and 8 are connected.

Next, the operation for removing the trunk guard 3 from the handrails 1 and 2 will be explained. To perform this operation, first, the tip of the engagement pin 22 is pressed from below the handrail 1 with, for example, a finger.
At this time, the presence of the recess 21 facilitates pressing the engagement pin 22 deeper. By pressing the engagement pin 22 in this manner, the engagement pin 2
2 escapes from the engagement hole 20. At the moment of this escape, the slide member 12, which had been urged in the protruding direction by the compression spring 17, moves the insertion member 18,
It acts in the direction of protruding from the cavity 10. Therefore, the body guard 3 is automatically moved as shown in FIG.
is separated from the handrail 1. Then, in the handrail 1 after removing the trunk guard 3, the slide member 12 slides according to the elasticity of the compression spring 17 until the outward flange 15 engages with the inward flange 16, and the lid 13 The opening 9 has just been brought to a closing position.

Although this invention has been described above in connection with the illustrated embodiment, various other modifications are possible within the scope of this invention.

For example, if the lid 13 of the slide member 12 is
A set of outward flanges 15 and inward flanges 16 serves as a stopper means for defining the end of the sliding movement of the slide member 12 so that the slide member 12 does not protrude any further from the cavity 10 when the slide member 12 assumes the closing position. In addition to mating, other forms of engagement combination mechanisms or link mechanisms;
You can also change it to .

In addition to the illustrated compression spring, spring means for biasing the slide member 12 to slide in the direction in which the lid 13 takes the position where the opening 9 is closed may be used.
Other forms of springs or other arrangements of springs may be employed.

Further, as the releasable engagement means for maintaining the state in which the insertion member 18 is inserted into the cavity 10, an engagement member 19 consisting of a combination of an engagement pin 22 and a spring 23 as illustrated, and an engagement hole 20, for example, other modifications may be considered, such as configuring the engagement member with a leaf spring or an elastically deformable resin plate.
