Abstract

A brake link mechanism including a first link (2) having one end slidably connected to a casing (1) and an opposite end fixed to the brake pedal (3) on one rear wheel assembly of a baby cart, and a second link (2) having one end slidably connected to the casing (1) and an opposite end (6) fixed to the brake pedal (3) on the other rear wheel assembly of the baby cart, whereby pressing on either brake pedal (3) causes the other brake pedal to be simultaneously depressed, and therefore the two rear wheel assemblies of the collapsible baby cart are simultaneously stopped. <IMAGE>

Description

BRAKE LINK MECHANISM FOR BABY CARTS BACKGROUND OF THE INVENTION The present invention relates to a link mechanism for baby carts, and more specifically to a link mechanism which simultaneously causes stoppage of the two rear wheel assemblies of the baby cart when the brake pedal on either rear wheel assembly of the baby cart is depressed.
A normal baby cart generally comprises two rear wheel assemblies, each having a brake mechanism controlled by a respective brake pedal for stopping the movement of the baby cart. As illustrated in Figure 1, each rear wheel assembly of a normal baby cart is generally comprised of two wheels 4 bilaterally mounted on a wheel holder 5 fastened to the frame 6 of the baby cart, a brake pedal 3 mounted on the wheel holder 5, and two clicks 31 coupled to the brake pedal 3.
Depressing the brake pedal 3 causes the clicks 31 to respectively engage into either groove 41 on either wheel 4, and therefore the wheels 4 are stopped.
Pulling the brake pedal 3 upwards causes disengagement of the clicks 31 from the wheels 4, and therefore the wheels 4 can be moved forwards or backwards. Because the brake mechanism on either rear wheel assembly is separately operated, the same brake operation should be respectively employed to each of the two rear wheel assemblies.
SUMMARY OF THE INVENTION The present invention has been accomplished under the aforesaid circumstances. It is therefore the principal object of the present invention to provide a brake link mechanism which allows the two rear wheel assemblies to be simultaneously stopped when the brake pedal on either rear wheel assembly is depressed.
Another object of the present invention is to provide a brake link mechanism which fits any of a variety of wheel tracks. Still another object of the present invention is to provide a brake link mechanism which does not hinder the collapsing operation of the baby cart in which it is installed. According to the present invention, two links are respectively connected to the brake pedal on either rear wheel assembly of a baby cart, and joined by a casing. The links are made to slide in and out of the casing so that the brake link mechanism can be adjusted to fit any of a variety of wheel tracks or to let the baby cart to be collapsed.
A unitary hook is made on each link and stopped by a respective stop portion on either end of the casing, and therefore the links do not disconnect from the casing.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a plan view showing the brake mechanism arranged on a rear wheel assembly according to the prior art; Fig. 2 is a perspective exploded view of a brake link mechanism according to the present invention; Fig. 3 is a longitudinal sectional view of the brake link mechanism of the present invention; Fig. 4 is an installed view showing the brake link mechanism connected between the two rear wheel assemblies of a baby cart; and Fig. 5 is similar to Fig. 4, but showing the condition of the-brake link mechanism as the baby cart is folded up.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figures 2 and 3, a brake link mechanism in accordance with the present invention is generally comprised of a casing 1, and two links 2. The casing 1 comprises two inverted T grooves 11 disposed in parallel with each other and vertically spaced through the length of the casing. The upper inverted T groove has one end fully opened and formed into an entrance 12 on the left end of the casing 1 and an opposite end partially closed and formed into a stop portion 13 on the right end of the casing 1; the lower inverted T groove has one end fully opened and formed into an entrance 12 on the right end of the casing 1 and an opposite end partially closed and formed into a stop portion 13 on the left end of the casing 1.
Therefore, the casing 1 has an entrance 12 above a stop portion 13 on the left end thereof, and a stop portion 13 above an entrance 12 on the right end thereof.
Alternatively, the entrance and stop portion on either end of the casing 1 may be invertedly disposed. The links 2 are respectively made from a flat, elongate plate and symmetrically arranged to slide in and out of either groove 11 on the casing 1 Each link 2 has a round hole 21 on a front end thereof and a hook 22 on a rear end thereof. The hook 22 is made by punching the material of the link itself. By inserting the front end of either link 2 from the entrance 12 on either groove 11 through the stop portion 13 of the respective groove 11, the two links 2 are coupled to the casing 1 in the reversed directions.
Referring to Figure 4, the round hole 21 on either link 2 is respectively fastened to the brake pedal 3 on either rear wheel assembly of an existing baby cart by a respective rivet 25. Of course, any suitable fastening means may be used to fasten either link to the brake pedal on either rear wheel assembly.
When assembled, the hook 22 on the link 2 at the upper elevation is disposed upwards, and the hook 22 on the link 2 at the lower elevation is disposed downwards.
The hook 22 prevents disconnection of the respective link 2 from the casing 1 as the respective link 2 is fully extended out of the casing 1. When installed, the brake pedal 3 on one rear wheel assembly is linked to the brake pedal 3 on the other rear wheel assembly by the casing 1 and the links 2. Therefore, stepping on the brake pedal 3 on either rear wheel assembly of the baby cart causes the brake pedal 3 on the other rear wheel assembly to be simultaneously depressed, and the respective clicks 31 are then moved by the respective brake pedal 3 to engage into grooves 41 on the wheels 4 of each rear wheel assembly of the baby cart to stop the two rear wheel assemblies simultaneously. On the contrary, when the brake pedal 3 on either rear wheel assembly is pulled upwards, the brake pedal 3 on the other rear wheel assembly is simultaneously carried upwards by the brake link mechanism, and therefore the two rear wheel assemblies are simultaneously released.
Referring to Figure 5, because the two links 2 are made to slide in and out of the casing 1, the brake link fits any of a variety of wheel tracks, and the installation of the brake link mechanism does not hinder the collapsing operation of the baby cart.

Claims (2)

What is claimed is:
1. A brake link mechanism comprising a casing having two parallel grooves through the length, a first link and a second link respectively made to slide in said two parallel grooves in the reversed directions, said first link having one end fastened to the brake pedal of one rear wheel assembly of a baby cart and an opposite end terminated to a unitary stop hook stopped by a first stop portion on one end of said casing, said second link having one end fastened to the brake pedal on the other rear wheel assembly of said baby cart and an opposite end terminated to a unitary stop hook stopped by a second stop portion on an opposite end of said casing, whereby stepping on the brake pedal on either rear wheel assembly causes the brake pedal on the other rear wheel assembly to be simultaneously depressed.
2. A brake link substantially as hereinbefore described with reference to the accompanying drawings.
