Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for attaching an auxiliary seat, which can be used as an infant seat in an automobile, to a baby carriage frame.

[Conventional technology]

When an infant is placed in a car, the infant is placed in an auxiliary seat installed in the car seat.

Furthermore, when the infant is dropped off, the baby carriage loaded in the car is unloaded, and the infant is placed on the stroller.

[Problem that the invention aims to solve]

Since the auxiliary seat and the baby carriage were purchased separately, there was a problem in that it resulted in a large expense.

In addition, since both the baby carriage and the auxiliary seat are stored when not needed, there is also the problem that a large space is required.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention consists of a substantially horizontal support frame, a side frame with a pair of left and right grips attached to the surface side of the support frame and facing each other, and the lower ends of the both side frames. It consists of a baby carriage frame composed of front wheels and rear wheels that are respectively pivotally supported in the front and rear, and an auxiliary seat for infants that can be placed on an automobile seat and the above-mentioned support frame, and a support member between the rear edges of the both sides of the frame. erected,
A pair of sliders having ends facing each other and protruding outward from each other are slidably attached to this support member, and a spring is provided to pull both sliders inward, and a spring is provided that rotates through the support member. The center of the cam that fits between the ends of the slider is fixed to the tip of the rotating shaft with the operating member attached, and hooks that fit into the recesses on both sides of the auxiliary seat are provided at the tips of both sliders. The upper end of the operating member is rotatably attached to the lower side so that it can swing back and forth, the lower end of an arm is rotatably attached to the upper part of this operating member, and the protrusion on the front edge of the auxiliary seat is attached to the upper end of the arm. It is constructed by providing a hook that fits into and locks the part.

[Effect]

When using it as a baby carriage, place the auxiliary seat on the support frame and then rotate the cam using the operating member to release the push-out of both sliders.
Since both sliders are pulled back by the spring, the hooks are fitted into the recesses and locked, thereby supporting the rear part of the auxiliary seat.

Also, after locking the hook to the protrusion of the auxiliary seat,
When the arm is lowered while rotating the operating member in the falling direction, the front edge of the auxiliary seat is pulled downward and supported.

Next, when used in an automobile, the cam is rotated by the operating member to push both sliders out of each other and the hook to escape from the recess.

Also, the operating member is rotated in the direction in which it is locked, the arm is raised, and the hook is removed from the protrusion.

Thereafter, the auxiliary seat removed from the support frame is placed on the seat of the automobile and fixed with a seat belt.

〔Example〕

In the figure, A is a baby carriage frame.

As shown in FIGS. 1 and 2, the above-mentioned baby carriage frame A includes a substantially horizontal support frame 1 and a pair of left and right grip portions 2 attached to both sides of the support frame 1 and opposed to each other.
The attached side frames 3, 3, the vertical rods 25 whose upper and lower ends are attached to the end of the support frame 1, and the lower ends of both side frames 3 and both vertical rods 25, respectively, bear bearings. It is composed of a front wheel 4 and a rear wheel 5.

Note that the receiving frame 1 may have a rectangular shape instead of the illustrated U-shape with both ends facing rearward.

Further, the baby carriage frame A may be of a foldable type as shown in the drawing or a non-foldable type (not shown).

B is an auxiliary seat placed on the support frame 1. This auxiliary seat B is removed from the stroller frame A, placed on the seat of a car, and secured with a safety belt, etc., when placing an infant in the car. Use as an auxiliary seat.

The method of attaching the auxiliary seat B to the baby carriage frame A is as follows: the ends of the support members 6 are fixed in the middle of both vertical rods 25, and a pair of sliders 7 are attached to the support members 6 with their tips protruding outward from each other. , 7 are provided to be slidable, and both sliders 7, 7 are pulled back by a spring 8. A shaft 10 with an operating member 9 is rotatably supported on the support member 6.
A cam 11 fixed to the slider 7 is interposed between the ends of the sliders 7, 7, and hooks 13 are provided at the tips of the sliders 7, 7 to fit into the recesses 12 on both sides of the auxiliary seat B. Rotate 90 degrees from the position indicated by the chain line in Figure 5 to the position indicated by the solid line, push out both sliders 7, 7, and after placing the auxiliary seat B, turn the cam 11.
When rotated 90 degrees, both sliders 7,
7 is pulled back, the hook 13 is fitted and locked into the recess 12, and the rear part of the auxiliary seat B is supported.

Both sliders 7, 7 have a box 14 attached to the support member 6, and are inserted into the through holes 15 in both side walls of the box 14, and a pin 17 protruding from the box 14 is inserted into the elongated hole 16 of the slider 7. Let me guide you.

Further, the upper end of the operating member 19 is attached to the lower side of the front edge of the receiving rack frame 1 via a pin 18 so as to be able to swing in the front-rear direction, and the lower end of the dogleg-shaped arm 20 in the middle of this operating member 19 is rotatable. Furthermore, a hook 21 is provided at the upper end of the arm 20, and after the auxiliary seat B is placed, the operating member 19 is rotated in the tilting direction (third counterclockwise direction), and at the same time, the operation member 19 is rotated upward from the front edge of the auxiliary seat B. The hook 21 is engaged with the protrusion 22 protruding toward the auxiliary seat B, and the lower end of the operating member 19 is positioned further back than the pin 18 to prevent the arm 20 from rising, thereby supporting the front edge of the auxiliary seat B.

As shown in the figure, if the inverted V-shaped groove 23 provided on the bottom of the auxiliary seat B is fitted with the rod 24 horizontally installed between both sides of the support frame 1, the auxiliary seat B It is possible to perform positioning and stop the slide.

〔effect〕

As described above, according to the auxiliary seat attachment device of this invention, when the push-out of both slides by the cam is released, both sliders are pulled back by the spring, and the hooks fitted and locked in the recesses of the auxiliary seat are released. This prevents the hook from coming off during travel, and also prevents the front edge of the auxiliary seat from lifting up during travel due to the engagement of the hook of the arm with the protrusion.

Furthermore, the auxiliary seat can be easily and quickly taken out by pushing out both sliders by rotating the cam and by raising the arm by the operating member.
