Description

[Detailed Description of the Invention] The present invention relates to a protective frame for a baby stroller, and particularly to a protective frame for use in a baby stroller or the like whose main body is foldable.

The purpose of this invention is to prevent the guard frame located on the upper surface of the tip of the armrest during use from moving to the end surface of the armrest as the stroller is folded and interfering with the folding operation of the stroller. The aim is to provide a protective frame for baby strollers, etc.

When carrying a baby in a so-called stroller, the front side of the seated infant is almost unprotected, so if the infant is active or the stroller is suddenly stopped, the infant may fall onto the floor. There was a danger of falling from the front.
In order to prevent these dangers, seatbelts are attached to the seat floor, which is not preferred because the tightening of the belt restricts the movement of the infant. A device was developed that prevents infants from falling by holding them out.

This guard frame is very good in that it does not restrict the movement of the infant on the seat floor, but unlike seat belts, it is a hard rod-shaped frame rod, so it is difficult to fold the stroller body for storage. I had the inconvenience of having to remove it when I needed to use it. The present invention aims to eliminate these drawbacks, and has been able to achieve its purpose by completing the invention described below.

Embodiments of the present invention will be described below with reference to the drawings.

The stroller of this invention has 1 push rod, 2 seat frames,
The armrest 3, front leg lever 4, and rear leg lever 5 constitute a frame, and two links 6, 7 are attached to these frame.
The entire structure is constructed by extending the step 8, and by releasing the abutment area between the bracket 9 provided at the lower end of the hand lever 1 and the rear leg lever 5, the folding is performed in a manner in which the lengths in the front and rear direction are close to each other. (See Figure 2).

Reference numeral 10 denotes a guard frame detachably and foldably attached to the tip of the armrest 3. This guard frame 10 can be folded into a U-shape in plan by dividing a frame long enough to pass over the armrests 3, 3 into approximately three equal parts, and pivoting the parts at the three equal parts. The guide joint 11, which can be undulated and swung only in the length direction of the guard frame, is installed at both ends of the guard frame, and a holder 12 is rotatably attached to the tip of the guide joint. Reference numeral 31 to which the insert leg rod 13 is attached is a sliding groove of the insert leg rod 13 that is split from near the tip of the upper side of the armrest 3 to the end surface. The insertion leg rods 13 provided at both ends of the guard frame 10 are removably engaged with a bracket 14 pivotably pivoted inside the tip of the armrest 3, and this bracket 14 is connected to the front leg rod 4.
It is designed to oscillate according to the ups and downs of the area. 15
is a locking recess formed near the lower end of the insertion leg 13, and is removably engaged with a locking pawl 14a swingably provided on the bracket 14.

Reference numerals 14b and 14c are claws for raising and lowering that protrude from the lower end of the bracket 14. An operating pin 41 is provided at the upper end of the front leg lever 4 pivoted to the armrest 3, and the operating pin 41 is connected to the two claws 14b. ,14c
It is located between the two claws 14b and 14c during operation, and the front leg lever 4 is engaged with the rear leg lever 5 for folding.
When the bracket 14 is tilted in this direction, the actuating pin 41 pushes the claw 14c to tilt the entire bracket 14 in the direction of the end surface of the armrest 3. (Accordingly, the insertion leg lever 13 also tilts forward, so the guard frame 10 also moves toward the end surface of the armrest 3.) Conversely, when the front leg lever 4 is raised during use, the operating pin 41 engages the claw 14b of the bracket. By pressing , the entire bracket 20 is operated in the opposite manner to the above, and the guard frame 10, which was located on the end surface of the armrest 3, is moved to be located above the armrest 3.

The present invention configured as described above can have the following effects.

(i) Since the guard frame 10 is detachably attached to the armrest 3, it can be easily removed when it is not required to be used. Moreover, after the guard frame 10 is removed, the armrest 3 can be covered with a cover, etc. It can be used as is without being installed.

(ii) The guard frame 10 detachably attached to the tip of the armrest 3 is attached to the armrest 3 via the insertion leg rods 13 attached to both ends of the guard frame 10, and the insertion leg rods are installed inside the armrest 3. Since the bracket 14 that holds the armrest 13 is pivotally mounted so as to be able to swing freely, the guard frame 10 can be moved from the top surface of the tip of the armrest 3 to the end surface (so-called wife side) as the stroller body is folded. This eliminates the inconvenience of having to finally remove the guard frame 10 when folding the stroller.
