CHILD BUGGY EMERGENCY BRAKE FOR BABYSTYLE OYSTER
Our client suffers from epilepsy and was concerned about having an attack and
possibly loosing control of a buggy carrying her young child - especially on hills.
The buggy was a popular Babystyle
Oyster model, with a simple parking brake which pushes rods beneath the rear axle tube out into "cogs" on the inside of
each rear wheel.
We added an additional emergency brake comprising hinged bars mounted above the axle tube,
which are held up by means of a cord by the client, but on release (e.g. in the event of the client letting go), drop down onto the same
brake cogs, and stop the buggy when the arms then hit the upright tubes.
The difficulty was ensuring any solution catered for
the folding mechanism, and was also removable if the buggy is sold on in the future.
Clamps were fashioned from jubilee clips, and a saddle formed from soldered brass sheet and square bar. Strong round neodymium
magnets were glued and screwed in place. The axle tubing was protected from marking with Dycem non-slip stick on plastic.
To ensure the brake cord was routed correctly, guides were constructed for the handle tubing from sections of vacuum cleaner drive
belt, with aluminium clamps, nylon P clips, and "lobster" clips.
The arms of the brake were formed from sections of aluminium angle. A pad of closed cell EVA foam cushions the braking slightly
as the arm hits the rear upright tube of the buggy. The sections of aluminium in the centre of each arm prevent the buggy rolling
back once the arm has dropped into place and stopped it.
The arms are secured into acetal plastic blocks, which are drilled out to take a second neodymium magnet which is screwed and glued
in place. To ensure the arms stay parallel to the axle and don't vibrate out of position, circles of Dycem non slip material
are stuck to the magnet in the acetal block.
This simple handle clip holds the brake cord if the emergency brakes aren't required.
Adhesive lined heat-shrink sleeve is applied to the brake cord to ensure it is always held in the correct position by the client.
