Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a hanger bed attachment device for a children's play vehicle.

<Conventional technology and its problems> A child's guardian is placed from behind on the body of a play vehicle that allows the child to steer and operate the pedals on his/her own while sitting on the seat. There is a conventionally known technology in which a push lever that can be steered and a hammock for sleeping an infant are removably attached to the vehicle so that the vehicle can be used as a so-called stroller depending on the age of the infant.
The present applicant has already proposed Utility Model Application No. 59-118690, and has achieved considerable results.

However, as a result of extensive research since then, it has been found that in the case of the above-mentioned known device, the hammock used as a bed for the infant to sleep on is made of a flexible sheet material such as leather or vinyl; A separate support is required, and the work of attaching it to the body is extremely troublesome. And even if it could be supported through a support,
When an infant turns over in bed, the hammock shakes and sways, creating problems with the stability and rigidity of the attached condition.

In addition, the handrail rods for hanging the hammock and its supports are exposed, and the hanging depth of the hammock is shallow, making it impossible for young children to sleep safely and causing the play vehicle to overturn. When consideration is given to collisions with other objects, it is inevitable that the user still feels uneasy.

<Means for Solving the Problems> The present invention is intended to improve these problems, and for this purpose, the frame rods surrounding the seating seat and the leg opening are replaced with the top surface of the body. A hanger bed is molded from hard synthetic resin into a tray shape with a roughly U-shaped cross section. is fitted into the body so that at least the leg opening can be shielded, and
The flange projecting from the peripheral edge of the hanger bed is attached to the frame rod of the body from above and is detachably locked and fixed thereto.

<Example> Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated example. In Figures 1 to 3, which schematically represent the entire outline of the child's play vehicle, A is made of hard synthetic resin or metal. The body is made from plates and has an inverted U-shaped cross section with an open bottom.
A leg opening 10 is provided in the center. The front part of the body A, which is divided into two parts by the leg opening 10, is continuously bulged downward as a box wall 11 having a substantially U-shaped cross section. 12 is fixedly suspended horizontally.

A front wheel steering mechanism 13 is attached to the front axle 12 and includes a steering handle 14, a tie rod 15, a knuckle arm 16, a steering angle regulating plate 17, and the like. 18 is a pedal support bar that is fixed and horizontally suspended parallel to the front axle 12;
A pair of left and right pedals 19 hanging from this
is adapted to be operated by stepping on it with the tip of the infant's foot inserted through the leg opening 10.

The rear part of the body A also bulges downward as a seat support wall 20 with a substantially U-shaped cross section. A seat 21 for sitting is provided on the top surface of this support wall 20, and the front and rear of the seat 21 is provided on the bottom surface. Advance/retract operation mechanism 22
and a rear axle 23 that rotates with a crank. After that, the axle 23 and the pedal 19 are
Since the vehicle is pivotally connected via the pair of left and right swing arms 24, the vehicle can run while rotating the rear wheels by stepping on the pedals 19.

Reference numeral 25 designates a reinforcing metal fitting that is backed and fixed from below to the center of the rear end of the body A, and, as is clear from FIG. . Reference numeral 27 denotes a pivot shaft loosely inserted into the sheath tube 26, the upper end of which is exposed in advance by a certain height from the top surface of the body A. 28 is a retaining pin of the support shaft 27, 29 is a washer, and 30 is a wing piece that is integrally extended from the lower end of the rotation support shaft 27 in a sideways horizontal state. A connecting bracket 31 of the L-shaped plate piece is pivoted so as to be freely swingable about a vertical axis.

On the other hand, in the middle of the front axle 12, an L-shaped rotating piece 32 that swings around the vertical axis is pivotally mounted, and one end of the rotating piece 32 and the connecting bracket 31 are connected to each other. , are pivotally connected by a forward/backward adjustment rod 33, and the other end of the rotating piece 32 is similarly engaged with the tie rod 15. Therefore, if the rotation support shaft 27 exposed from the body A is rotated using the push lever described later,
Steering of the front wheels becomes possible.

34 is a seat 21 for sitting in the leg opening 10.
It is a surrounding frame rod made of a metal pipe that is fixedly installed on the top surface of the body A by bolts 35 so as to surround the peripheral position of the body A, and both ends of the separated front part are inserted into the body A. This enclosure frame rod 34 functions as a reinforcing member to prevent distortion and deformation of the body A, and also allows the body A to be carried while being held. Handrail portion 34a of the lid and enclosure frame rod 34
The finger insertion gap S is maintained together with the top surface of the body A, and the backrest portion 34 is also
This is because b also floats a certain height H1 from the top surface of body A.

Reference numeral B designates a hanger bed which is fitted into the body A from above by utilizing the above-mentioned surrounding frame rod 34 as it is, and is pre-molded from a hard synthetic resin as shown in FIGS. 5 to 13.

That is, the hanger bed B has a tray shape or a bathtub shape with a generally U-shaped overall cross section that fits into the leg opening 10 and the seat support wall 20 of the body A, and its peripheral edge is similar to the body A. The overhanging flange 36 that covers the enclosure frame rod 34 is curved into a substantially inverted L-shaped cross section with a constant band width. In this case, in the illustrated example, the leg opening 10 of the body A can be completely covered by the front half of the hanger bed B, and the remaining rear half is opened in a so-called bottomless state.

The rear half of the hanger bed B overlaps with the seat sheet 21 on the seat support wall 20, so the seat 21, together with the hanger bed B, forms an overall bed on which the infant can sleep stably. It is based on having people participate in its functions. however,
Of course, the rear half of the bed B may be configured to have a bottom so that it overlaps with the sheet 21. In addition, in the illustrated example, the seat 21 is slid to the most backward position by its forward/backward movement mechanism 22, and then the hanger bed B can be fitted into the body A from above. The present invention can be applied in exactly the same manner to the body A in a fixed installation form in which the seat 21 does not move forward or backward. The body A is not limited to the above-described generally inverted U-shaped cross section with an open bottom.

Reference numeral 37 designates a pair of left and right reinforcing rib pieces that are located in the front half of the hanger bed B and hang down in the middle of the overhanging flange 36 as if to partition it, and are compatible with the surrounding frame rod 34 of the body A. Each of the locking grooves 38 is cut out to open downward. Reference numeral 39 denotes a lapper-shaped guide notch that is continuous with the entrance of the locking groove 38 and acts to guide the enclosure frame rod 34 into the locking groove 38 smoothly.

That is, when the overhanging flange 36 of the hanger bed B is pushed into the enclosure frame rod 34 of the body A from above in its front half, the locking groove 38 of the reinforcing rib piece 37 is pushed into the enclosure frame rod 34.
It is designed to smoothly fit and lock, and can also be removed and disassembled by pulling up.
It should be noted that the locking groove 38 of the reinforcing rib piece 37 is positioned corresponding to the handrail portion 34a of the enclosure frame rod 34 having the finger insertion gap S, as suggested from the illustration.

Reference numeral 40 denotes a pair of left and right locking holes which are also located at the rear end of the hanger bed B and are opened in the projecting flange 36 thereof, and each of these locking holes is connected to the body A by a pair of front and rear wedge claws 41 facing each other.
The frame rods 34 of the frame are forcibly held in place. When the overhanging flange 36 of the hanger bed B is pressed from above to the position of the backrest portion 34b that floats by the above-mentioned fixed height H1 of the enclosure frame rod 34, the wedge claws 41 are forcibly expanded and its restoration is performed. Due to its elasticity, the enclosure frame rod 34 is firmly fitted into and locked into the locking hole 40, and can also be removed by pulling up forcefully.

Reference numeral 42 denotes a pair of left and right pawl receiving holes which are located near the locking hole 40 and are also formed at the rear end of the overhanging flange 36; A wedge-shaped locking pawl 44 is inserted from above and locked. The pillow 43 is separate and independent from the hanger bed B itself, and is also molded from hard synthetic resin into an approximately inverted U-shaped cross section as shown in Figures 14 and 15, and is assembled with the hanger bed B. As a result, the child's head can be held in a stable manner. However, it is also possible to bulge out the pillow 43 continuously and integrally from the hanger bed B itself.

Further, reference numeral 45 denotes a pusher lever which is detachably fitted to the rotational support shaft 27 exposed from the top surface of the pusher lever at the rear position of the body A. By operating it, the child's guardian can steer the front wheels from the rear of the vehicle. 47 is a fixing bolt of the pusher rod 45, 48 is a recess cut out in the pivot shaft 27 to receive the bolt 47, and 49 is a nut that is welded to the pusher rod 45 in advance. The bolt 47 is screwed and fastened.

Reference numeral 50 denotes a relief groove for the pusher rod provided at the center of the rear end of the overhanging flange 36 in the hanger bed B, and matches a relief groove 51 of the same purpose provided in the pillow 43. 52 is a relief groove for the steering handle 14 formed at the center of the front end of the hanger bed B, and the pusher rod 45 and the steering handle 14 are inserted into these relief grooves 50, 51, and 52. It can be said that this positioning action also stabilizes the attached state of the hanger bed B.

<Function> According to the above configuration, in the form shown in FIGS. 1 to 4 in which the hanger bed B and pusher rod 45 are removed, the play vehicle can be driven and used by the foot operation of the pedal by the child seated on the seat 21. In addition, the 9th to 1st
As shown in Figure 1, by attaching the hanger bed B and the pusher rod 45, the infant can be placed on the hanger bed B, and the parent can push the pusher rod 45 from behind.
By steering the stroller 5, it can also be used as a stroller.

At this time, the hanger bed B is made of hard synthetic resin in the form of a rigid tray or bathtub, and is fitted from above to the enclosure frame rod 34 of the body A, so that it is easy to sleep. It is extremely safe for infants inside and extremely stable against its movements. Regarding its safety, hanger bed B must be at a certain height H from the frame rod 34 of body A.
The fact that it stands tall by 1 and has a fairly deep U-shaped cross section also works effectively.

Incidentally, by attaching, for example, a screw or a hook to the rear end of the overhanging flange 36 of the hanger bed B and releasably locking it to the enclosure frame rod 34 of the body A, the vehicle can be prevented from rolling over. It is effective to set the hanger bed B so that it will not fall off from the enclosure frame rod 34 even in the event of a collision with another object, and this will further improve safety. .

<Effects of the invention> As described above, in this invention, the sitting seat 21
and a surrounding frame rod 34 surrounding the peripheral position of the leg opening 10.
is fixedly installed on the top surface of the body A, and a push lever 45 for steering the front wheels is installed at the rear of the body A.
In a children's play vehicle, in which a hanger bed B is removably attached, a hanger bed B formed from a hard synthetic resin into a tray shape having a substantially U-shaped cross section is fitted into the body A so as to be able to cover at least the leg slot 10. At the same time, the flange 36 protruding from the peripheral edge of the hanger bed B is attached to the frame rod 34 of the body A from above and is removably locked and fixed thereto, which eliminates the problem of the prior art described at the beginning. It has the effect of completely eliminating the Mondai point.

In other words, by simply pushing in the hanger bed B from above, it can be firmly and stably fitted into the surrounding frame rod 34 of the body A, and moreover, in this state of use, the child can It will be extremely safe. As a necessary configuration for this purpose, a simple one that effectively utilizes the frame rods 34 of the body A is sufficient, so it can be said to be a very useful device.
