Accessible archery

Posted on

This spring, Triple Helix once again partnered with a Virginia Commonwealth University occupational therapy doctoral student to develop assistive devices for people in the Hampton Roads region. The team created this accessible bow mount for Camp Bruce McCoy, a residential summer camp for adults with a brain injury in Chesapeake, Virginia.  This device will enable single-arm operation of a recurve bow which will be mounted in the shooting gallery at the camp.  The team provided both right-handed and left-handed versions of the bow mount to the camp.

The bow mount is fabricated from laminated sheets of 1/4″ clear polycarbonate.  Triple Helix cuts this material on our 80-watt laser cutter, but these parts can alternatively be fabricated with more common shop tools (e.g. jigsaw, hand drill).  The bow mount enables the user to aim the bow in both the azimuth and elevation directions before shooting an arrow.  The bow can be installed at any height, enabling archery practice for both standing and seated users.

Large-scale storage solutions

An immediate goal for Triple Helix is take over a small closet which adjoins our workshop. The closet currently stores JROTC uniforms and other supplies, so to acquire the closet we’d need to come up with another location to store these items. One possibility is an in-kind donation of metal wardrobe storage cabinets or lockers.

Menchville High School currently stores equipment in 7 sheds and shipping containers located around the campus and in various states of repair. Summed together these storage spaces provide about 2000 sq ft of storage for school groups including band, drama, and athletics. Triple Helix seeks to consolidate this storage into a large engineered steel storage building, which would provide enough clean dry storage for all school activities.

Miscellaneous

  • Prepaid fuel cards
  • Gift cards to our common vendors (Lowe’s, Home Depot, Amazon, etc.)

Accessible controls for ride-on toy car

Posted on

This spring, Triple Helix partnered with an occupational therapy doctoral student from Virginia Commonwealth University to develop assistive devices for people in the Hampton Roads region. Through communication with the Children’s Assistive Technology Service (CATS) a need was identified for a modified ride-on toy car, based on the University of Delaware’s GoBabyGo project. This project aims to provide access to low-cost mobility devices for young children without other means of exploring their environment. In this case, the recipient was a young girl who does not have the ability to move her lower extremities as a result of a birth defect.

To provide access to the car’s controls, a 5-inch switch was mounted on the steering column and wired via a relay switch to the car’s motor to replace the foot pedal function. Additionally, PVC handles were added on each side of the center switch for more ergonomic steering control. To also allow for simultaneous propulsion and steering, the handles fit over a laser-cut Lexan frame which, when flexed, activate an additional limit switch on each side of the steering column. This design concept can be applied to other ride-on cars, depending on a particular child’s needs and functional abilities.
