| 20100062878 | Green Tees TM,; Tee GreenTM: Green Planet Golf Tees, TM - Green Tees, Tee Green, Green Planet Golf Tees look and perform like an average golf tee in connection with the game of golf, but in connection with the Environment, they are constructed of plant nutrients designed specifically to release nutrients continuously in soil and grass thereby feeding the adjacent vegetation, foliage, grass, fairway, teebox or woods. | 03-11-2010 |
| 20100093469 | GOLF TEE AND METHOD - A golf tee comprises substantially conically ball support component with a substantially annular edge substantially surrounding a central recess. The recess is sufficiently deep so that an annular surface area of the ball touches the edge along a circular contact zone when the ball is teed up. A shaft member extends from an apex of the ball support component and comprises a material that breaks or bends as a club head moves through a teed up golf ball to provide a resistance to such movement approaching zero. | 04-15-2010 |
| 20110086730 | BIODEGRADABLE SPORT OR GARDEN ARTICLES, AND APPARATUS FOR PRODUCING BIODEGRADABLE ARTICLES - A biodegradable sport or garden article such as a golf tee is formed from a material comprising filler material, which can contain grass seeds, and a degradable binder therefor, so that discarded tees enhance the surface of the golf course, rather than littering it. Apparatus for manufacture of such articles comprises respective storage containers ( | 04-14-2011 |
| 20110263353 | GOLF TEE AND IMPROVED MANUFACTURING METHOD FOR SAME - Golf tees are prepared from dowel blanks that are a composite material, rather than 100% wood, with the composite preferably being biodegradable, so it will weather away. | 10-27-2011 |
| 20130005511 | GOLF TEE REWINDING DEVICE - Rewindable golf tee. This includes a small rewinding device encased in a smooth edged multifarious holder with dampened press control element or pull to stop, pull to rewind system to safely rewind a golf tee via a strong flexible quality link. The aid can have two tees of varied lengths to suit golf club selection, two rewinding devices and two flexible connections. It can be cheap or expensive. The invention can support other golf gadgets such as pitch-mark repairer, ball marker, groove cleaner and/or score keeper. The invention can hold personal ID or corporate logo or advertisement. The invention is environmentally friendly. The tees can be made of more durable materials, with new special integrated finishes such as soft grip patterns. They can be easily replaced via connecting links. The rewindable tee device will sensibly save time on the tee box and avoid clutter in bags, pockets and/or greens. | 01-03-2013 |
| 20130137538 | BIODEGRADABLE GOLF TEE - A golf tee is 100% biodegradable and has a density and strength sufficient for the use to which it is destined, the materials making up the mixture not containing heavy metals or toxic elements. The plastic raw material is 100% biodegradable and has a specific weight of between 0.7 g/cm3 and 1.5 g/cm3. The material is composed of bioplastics formed by polymers of vegetable origin such as: rubber, latex, starch, fecula and cellulose, or of biodegradable thermoplastics derived from petroleum composed of biodegradable polymers and elastomeric polymers, such as synthetic rubber, together with a filler of inert and non-toxic minerals from the group of the carbonates and mineral salts, such as calcium carbonate, sodium bicarbonate or barium sulphate, up to a maximum of 50% of the mixture. | 05-30-2013 |
| 20130165273 | GOLF TEE WITH SUPPORT PRONGS - A golf tee includes: an elongate shaft having opposed upper and lower ends, the lower end configured to be inserted into an underlying surface; and a support cup that is configured to support a golf ball from beneath and that merges with the shaft. The support cup has a base portion and further includes at least three arcuate support prongs projecting upwardly from the base portion. The support prongs define a discontinuous annulus about the periphery of the support cup. | 06-27-2013 |
| 20140171224 | GOLF TEE WITH SUPPORT PRONGS - A golf tee includes: an elongate shaft having opposed upper and lower ends, the lower end configured to be inserted into an underlying surface; and a support cup that is configured to support a golf ball from beneath and that merges with the shaft. The support cup has a base portion and further includes at least three arcuate support prongs projecting upwardly from the base portion. The support prongs define a discontinuous annulus about the periphery of the support cup. | 06-19-2014 |
| 20150099597 | GOLF TEE WITH SUPPORT PRONGS - A golf tee includes: an elongate shaft having opposed upper and lower ends, the lower end configured to be inserted into an underlying surface; and a support cup that is configured to support a golf ball from beneath and that merges with the shaft. The support cup has a base portion and further includes at least three arcuate support prongs projecting upwardly from the base portion. The support prongs define a discontinuous annulus about the periphery of the support cup. | 04-09-2015 |
