Patent number: 5989093Abstract: A balloon weight and ribbon assembly includes a spool having a length of ribbon wound thereabout, the ribbon being secured at one end to the spool and at the other end to a breakaway tab which initially comprises a part and parcel of the spool. A dimple in the tab accommodates receipt of a double knot at one end of the ribbon, while a slot in the spool accommodates receipt of a double knot of the ribbon at the opposite end. A piece of double backed adhesive tape is provided on the breakaway tab to allow for securement of the tab to the neck or tail of an inflated balloon.Type: GrantFiled: April 18, 1997Date of Patent: November 23, 1999Assignee: David C.

Patent number: 5944576Abstract: A stick and cup assembly for receiving and securing a balloon includes an elongated stick with a cup maintained at one end thereof. The cup is formed integrally with the stick. A collar is slidingly received upon the stick for selective locking engagement with the cup for securing a balloon thereto. The stick is preferably formed of a composition of polyester and rubber such that the stick is capable of being manually formed into any desired configuration and which retains that configuration once so formed.Type: GrantFiled: June 29, 1998Date of Patent: August 31, 1999Assignee: David C. NelsonInventors: David C. Nelson, Bruce W. Walden

Patent number: 5653272Abstract: An automated balloon inflation device which has a supply of pressurized gas, a nozzle for receiving a balloon, and an actuator for sequentially closing a clamp on the balloon and the nozzle and subsequently supplying the pressurized gas to the balloon for the inflation thereof. Furthermore, a key-weight device may be employed for the dual purpose of controlling the supply of pressurized gas to the nozzle and to prevent the inadvertent loss of an inflated balloon which is secured to the key-weight. Additionally, the automated balloon inflation device is constructed so that any consumer may inflate a balloon with pressurized gas.Type: GrantFiled: February 2, 1995Date of Patent: August 5, 1997Assignee: David C.

Patent number: 5651402Abstract: An automated balloon inflation device which has a supply of pressurized gas, a nozzle for receiving a balloon, and an actuator for sequentially closing a clamp on the balloon and the nozzle and subsequently supplying the pressurized gas to the balloon for the inflation thereof. Furthermore, a key-weight device may be employed for the dual purpose of controlling the supply of pressurized gas to the nozzle and to prevent the inadvertent loss of an inflated balloon which is secured to the key-weight. Additionally, the automated balloon inflation device is constructed so that any consumer may inflate a balloon with pressurized gas. In another embodiment, the automated balloon inflation device employs a connection block with a series of conduits therein to interconnect the pressurized gas supply with the clamping mechanism and the nozzle. This embodiment employs a clamping mechanism which uses a piston attached to a gear wherein the gears rotate clamping jaws onto the nozzle.Type: GrantFiled: February 16, 1996Date of Patent: July 29, 1997Assignee: David C.

Patent number: 4921402Abstract: A valving mechanism for a balloon inflator is presented. The valving mechanism is attached to an inflator comprising a fan driven by a through-flow motor. A piston, received within a cylinder, has two bores passing therethrough, the first bore communicating with atmosphere, and the second bore communicating with a nozzle adapted for receipt of a balloon neck. When the balloon is placed on the nozzle and the piston is urged against a spring, an airstream passes through the second bore to inflate the balloon. When the balloon is removed, a spring urges the piston to a position in which the airstream passes through the first bore to atmosphere reducing the load on the motor and allowing the motor to run cooler.Type: GrantFiled: May 1, 1989Date of Patent: May 1, 1990Assignee: David C.
