Title: Dale A Pulver: Innovator in Wheelchair Technology

Introduction

Dale A Pulver is a notable inventor based in University Heights, OH (US). He has made significant contributions to the field of wheelchair technology, holding a total of 4 patents. His innovative designs focus on enhancing the functionality and safety of wheelchairs for users.

Latest Patents

One of his latest patents is the "Weight-shifting reclining and tilting wheelchair seat." This invention features a recline mechanism for the chair back, allowing the seat to reposition forward in response to the recline. This design helps to reposition the user's weight relative to the supporting wheels. Additionally, the chair is equipped with a weight-shifting tilt mechanism and a bilateral tracking mechanism, which ensures controlled motion is transmitted to both sides, avoiding torque due to uneven loading. The back canes and brackets on the chair back are slotted for infinite adjustment of chair arms, ventilator trays, and other accessories.

Another significant patent is the "Anti-tip assembly for power wheelchair." This assembly extends from the frame of the power wheelchair and includes a plate secured via a dampening mechanism. A first arm extends from the plate, allowing for limited relative movement. A grounding engaging wheel at the distal end of the arm is urged toward the ground surface by a biasing spring. As the wheelchair begins to tip, resistive forces are generated by the biasing spring, which continues in a linear fashion until relative movement ceases. Further resistive forces are then provided by the dampener, ensuring safety during use.
