Description

[Detailed Description of the Invention] The present invention relates to an auxiliary bar attachment device for a stroller. Support bars are extremely important in preventing infants from falling out of strollers. However, when the baby grows older and is no longer worried about falling,
Rather, the auxiliary rod becomes a hindrance when the child is getting on and off the train, making it difficult to remove it. For this reason, many strollers equipped with removable auxiliary rods of various types are now on the market. However, in the auxiliary rod attachment devices announced so far, it is necessary to completely remove the attachment/detachment pin from the device when attaching or detaching the auxiliary rod, which often causes accidents in which the pin is lost. It has been difficult to fully obtain the attachment/detachment effect. Furthermore, attaching and detaching the auxiliary rod required extremely complicated operations.

The present invention aims to overcome the drawbacks of such known devices.

FIG. 1 shows a stroller 14 with an auxiliary rod 12 installed using the auxiliary rod attachment device 10 of the present invention.
An example is shown below. The auxiliary rod attachment device 10 of the present invention is not only used for this stroller 14 shown in the drawings, but can also be easily attached to other strollers and achieve similar superior effects. It is. In the figure, the device is shown attached to a "stroller" filed by the same applicant on December 7, 1981. Therefore, regarding the structure and function of the stroller itself, reference may be made to the specification of the same application.

The auxiliary rod attachment device 10 of the present invention is attached to the stroller 14.
It is housed in the tip of the armrest 16. As shown in FIGS. 1 to 3, the armrest 16 is preferably a hollow body molded from a synthetic resin material, and is attached to the front and rear legs and push rod of the stroller with pins through holes 13 and 15. ing. . Although the tip of the armrest 16 is slightly directed upward, this is not an essential requirement, and it is sufficient if there is a space inside that can accommodate the device 10.

The auxiliary rod attachment device 10 includes an auxiliary rod attachment 18;
A pin 20 that pivots the fixture 18 to the armrest 16
and a detachable pin 21 for attaching and detaching the auxiliary rod 12 to its fixture 18. In addition, there are various springs (not shown) and a stopper 46.

The auxiliary rod attachment 18 has a complicated shape as shown in FIG. 4, which is a perspective view thereof. That is, the front (5th
(Figure) A substantially rectangular auxiliary rod receiving opening 22 is formed in the center, and a latch hole 24 is formed in the upper part of the opening 22, and a detachable pin operation hole 26 is further provided in the lower part of the latch hole 24.
Another latch hole 25 is formed on the side of the holder.
Further, a hexagonal recess 28 is formed on the upper surface (FIG. 6). The recess 28 is not deep enough to reach the opening 22. A hole 30 leading to the opening 22 is provided in the recess 28, and further aligned with the hole 30,
A hole 32 is formed that communicates the opening 22 and the operation hole 26. The hole 30 is a stepped hole, and the opening 22 side is larger and has the same diameter as the hole 32,
The diameter of the recess 28 side is reduced at a stepped portion 34 .
Further, the side surface of the fixture 18 (FIG. 7) is provided with the hole 3.
A hole 36 extending in a direction intersecting the 0,32 axis is provided at the upper rear portion.

A hexagonal hole 40 as shown in FIG.
8 is fitted into this hole 40 so that its upper surface is positioned, and then the side hole 36 of the fixture 18 and the hole 17 at the front of the armrest 16 are aligned and the two are connected with the pin 20. An operation plate 4 having the same shape and depth as the recess 28 on the upper surface of the fixture 18 is provided.
2 is inserted. An end portion of a detachable pin 21 extending through the detachable pin operating hole 26, hole 32, opening 22, and hole 30 of the fixture is implanted and fixed to the lower side of this operation plate. Although the head diameter of the tip of the pin 21 is smaller than the diameter of the hole 32, the stepped portion 34 of the hole 30 cannot be passed through. Therefore, the operation plate 42 and the detachable pin 21 are connected to the recess 28 and the stepped portion 34.
Although it can move up and down between the two, it will not separate from the fixture 18. Note that there is a protrusion 44 on the side of the operation panel 42.
is provided to ensure a tight fit with the upper surface recess 28. Figure 9 shows the armrest slope 38 opening 4
FIG.
In FIG. 9, the number 46 indicates a stopper. The stopper 46, as shown in FIGS. 10 and 11,
It consists of a latch piece 48 that slides on the back side of the armrest slope 38, and an operating member 50 that slides the latch piece 48 on the surface of the slope 38, and both are connected via a long hole 52 provided in the slope 38. , can move up and down along the slope 38 within the elongated hole. The stopper 46 is constantly biased upwardly by a suitable spring by known means.

The fixture 18 is attached to the armrest 16 as shown in FIG.
When the latch piece 48 of the stopper 46 is fully inserted into the latch hole 24 on the surface of the fixture 18, as shown in FIG.
The fixture 18 remains stationary in that position. Of course, in this case, the auxiliary rod 12 has been removed from the stroller, and the operating plate 42 is tightly fitted into the recess 28.
In this state, a spring is arranged in the fixture 18 so that a clockwise spring force is accumulated around the pin 20. This spring arrangement can be done by winding the spring around the pin 20, or by wrapping the spring around the armrest 16 and the fixture 1.
8, a spring may be placed between the two.

However, when attaching the auxiliary rod 12, the operating member 50 of the stopper 46 is pulled down against the spring force. At this time, the latch piece 48 is released from the latch hole 24, and at the same time the fitting 18, which is biased clockwise by a spring, rotates clockwise around the pin 20 and pops out. After releasing the stopper 46, when the fixture 18 protruding from the hole 40 of the armrest 16 is further rotated clockwise by hand, the latch piece 48 of the stopper 46 slides on the curved surface 54 of the fixture 18 and is finally rotated. The latch piece 48 is inserted into the second latch hole 25 in the lower part of the fixture 18 as shown in FIG.
As a result, the upright position of the fixture 18 is restricted. After the fixture 18 is fixed, a finger is inserted into the detachable pin operating hole 26 and the detachable pin 21 is pushed up to push the operating plate 42 out of the recess 28. Thereafter, the operation plate 42 is depressed 2 until the head of the pin 21 engages with the stepped portion 34.
8 so that the pin 21 does not prevent the end fitting 56 of the auxiliary rod 12 from entering the auxiliary rod receiving opening 22. Guide the mounting portions 56 at both ends of the auxiliary rod 12 to the openings 22 of the both side fittings 18, and
Insert the detachable pin 21 into the hole 58 provided in the operation plate 4.
2 into the recess 28, the installation of the auxiliary rod 12 is completed.

When removing the auxiliary rod 12, conversely, remove the pin 21.
, lift the operation plate 42, pull out the pin 21 from the hole 58 of the auxiliary rod attachment part 56, and push the plate 42 into the recess 28. Furthermore, when storing the fixture 18 in the armrest 16 so that it does not become jammed, push down the stopper 46, pull the latch piece 48 out of the second latch hole 25, and then remove the fixture 1.
8 around the pin 20 in a counterclockwise direction. The latch piece 48 of the stopper 46 enters the latch hole 24 while sliding on the curved surface. This completes the storage and the 10th
The position shown in the figure can be obtained.

In this way, the present invention is extremely easy to operate.
The auxiliary rod can be attached and detached without separating the detachable pin from the vehicle body, so there is no need to worry about losing the pin, and the attachment can be pulled out only when necessary, and the attachment can be completely attached to the armrest when not in use. This completely prevents the risk of children getting their hands caught by storing it inside.
