Abstract

A pushcart brake device has a wheel 6, a wheel support seat 1, a slide plate 2, a drive disk 4, and a shaft 5. The wheel support seat 1 has a hollow interior 11, a socket 12, and a through hole 15. The wheel 6 has a click device 61 inserted in the hollow interior 11 of the wheel support seat 1. The socket 12 has a slide groove 13 receiving the slide plate 2. The slide plate 2 has at least one post 21, an oblong hole 20, and a distal click block 22. The drive disk 4 has an axle hole 40, and at least a groove 41,42 for receiving the post 21 of the slide plate. The shaft 5 passes through the axle hole 40 of the drive disk 4, the through hole 15 of the wheel support seat 1, the oblong hole 20 of the slide plate 2, and the wheel 6. A pedal 45 is connected to the drive disk 4. Pressing the pedal downwards causes the groove 41,42 and post 21 to slide the click block 22 to block rotation of the click device 61. Alternative embodiments have pedals of two brake devices connected by a rod (7', fig 5), or a central pedal (8'', fig 6) on a common wheel shaft.
