Open the CIPO recordAbstract From the Canadian patent
An improvement on the device disclosed in my previous U.S. Patent No. 4,637,532 for a device for assisting in the putting on of elastic hosiery. The current invention includes the improvement of providing an expandable tip to open the socking even wider than was possible with my previous device. The expansion is accomplished by dividing the portion over which the stocking is placed; biasing the two split parts to a normally closed position and providing a latch to, hold the device in an open position while it is in use.
