BRIEF SUMMARY
DESCRIPTION
1. Technical Field
This invention relates to strollers and more particularly to a stroller which because of the unique interrelationship of its frame elements is convertible to a backpack type carrying device.
2. Background Art
Strollers, perambulators and other devices for transporting children with less physical strain for the parents and greater comfort for the child are well known.
Traditionally, strollers have necessarily been rigid and somewhat bulky so that in use they would provide proper support for the child and keep the risk of injury to the child to a minimum. As a contra to the requirement for rigidity, since space has become a premium, it is extremely desirable that the strollers be collapsible such that they may easily be stored or transported when not in use.
The desirability and convenience of transporting children on the back of an adult is likewise well known and in the past, devices have been manufactured which essentially convert a backpack frame to a child carrier through the utilization of modified support and enclosing structure. These backpack/carrying devices are necessarily limited in that they are not easily converted for other carrying purposes and in general do not collapse. It is therefore not convenient to store the devices when it is no longer necessary to carry the child on the back.
Prior art known to the applicant include U.S. Pat. No. 3,984,115 granted to Miller which discloses a four wheeled stroller wherein the wheel supporting legs are selectively collapsible upwardly transforming the stroller into a rigid backpack child carrying device.
U.S. Pat. No. 4,157,837 granted to Kao on June 12, 1979 discloses a two-wheeled stroller having a rigid child enclosing framework wherein the handle may be collapsed downwardly allowing the device to be utilized as a backpack type carrier.
U.S. Pat. No. 956,399 granted to Morris on Apr. 26, 1910 discloses a collapsible tray and rack support wherein the elements are articulated so that the device may be collapsed.
U.S. Pat. No. 1,718,962 granted to Kimball on July 2, 1929 discloses a parcel or a luggage carrier which includes a main frame member capable of articulation at about midpoint as well as two horizontally extending bracket members held in position by articulated collapsible support elements such that the entire device may be collapsed for storage and the like.
U.S. Pat. No. 4,111,454 granted to Kassai on Sept. 5, 1978 discloses a folding baby carriage including intricate interconnecting members which are slideably interconnected or articulatable so that the device may be collapsed.
U.S. Pat. No. 4,256,325 granted to Fleischer on Mar. 17, 1981 discloses a collapsible frame for a baby carrier wherein the rear wheels supporting element and the baby supporting platform collapse towards the main frame when the handle member is collapsed.
U.S. Pat. No. D160,598 granted to Heideman on Oct. 25, 1950 discloses a collapsible baby stroller wherein the rear portion of the seat element is held in position by flexible straps allowing the device to collapse.
Norweigan Pat. No. 84948 granted Jan. 31, 1955 discloses another method of collapsing a baby stroller.
