Abstract: A golf tee has a contact alert material encapsulated therein. The golf tee includes a top portion with top, side and bottom walls fixedly attached to a shaft that terminates into a point appointed to be inserted into a ground surface. A cavity is formed between the top, side and bottom walls of the top portion. A contact alert material is encapsulated within the cavity and is composed of a combustible material that generates a spark on impact. The contact alert material is appointed to generate the spark during a golf swing when a golf club strikes the ball and the side walls. The alert is provided immediately as instantaneous feedback during the golf swing adapted to thereby improve muscle memory required to reliably replicate a proper golf swing.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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 (8-11) for grass seed and a hardenable binder therefor, means (4-7) for controlling sequential discharge of the seed and the binder to a mould (16) for forming an article under a pressure sufficient to ensure compaction of the mixture within the mould, and means for discharging the tee from the mould. The apparatus may be in the form of a vending machine, manufacturing and dispensing golf tees in response to payment.

Abstract: 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.

Abstract: 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.

Abstract: The invention is a new invention type of golf tee. It is used to position a golf ball at a certain height. This golf tee comprises a golf tee having upper and lower ends and a shaft of substantially uniform diameter connecting the ends, the upper end having a cup of a substantially uniform diameter for receiving a golf ball, the lower end being tapered for insertion into a playing surface, and the composition of the tee being a combination of natural materials bound by biodegradable materials, the natural materials consisting of waste products of healthy animals which will become wetted, slick, softened, and slowly disintegrate biologically as it lays on the ground and is exposed to the moisture of the ground, turf and course water over the subsequent few days. The process of disintegration will also be hastened by the grinding and cutting effect of the mowing of the course surfaces.

Abstract: A golf tee with a body portion having a first end for inserting into the ground and a second end for supporting a golf ball when the first end is inserted in the ground, wherein the body portion is constructed of a biodegradable material. A golf tee insertion device having a base for supporting the device, a mandrel for holding a golf tee to be inserted into the ground and an actuator for moving the mandrel toward the ground so that the golf tee is inserted into the ground, wherein the actuator controls a depth of insertion of the tee.

Abstract: A golf tee includes first and second symmetrical halves extending from a distal tip to an enlarged head and a sheet substrate sandwiched between the tee halves. The first and second tee halves are formed of a transparent material so that indicia, such as an advertisement or promotional message, printed on one or both opposite faces of the sheet substrate is visibly exposed along the stem of the formed tee. The two tee halves are joined together through several openings in the sheet substrate, thereby enhancing the bonding between the tee halves to form an integral unit. Use of a biodegradable material composition in the manufacture of the tee halves and sheet substrate, along with the divided structure of the first and second tee halves, enhances disintegration of the golf tee in the natural environment.

Abstract: A method for making a bamboo made golf tee has the steps of preparing an elongated rod, preparing a cylinder, trimming one end of the elongated rod to make the elongated rod have a sharpened end, trimming a periphery of the cylinder to make the cylinder to have a tapered end, defining a central hole in the cylinder and securely attaching the other end of the elongated rod in the central hole.

Abstract: The invented device is a golf tee that helps eliminate interference between a golf club and ball, and that reduces compression between the golf ball and tee to improve overall golf ball trajectory. The preferred tee includes a reduced circumference/cross-section zone along the shaft, which makes the tee more likely than conventional tees to break, deform or otherwise fail upon impact of the golf club head against the ball or the tee. Also, the preferred tee includes leading and trailing edges, relative to club movement, that are “scalloped” to produce a ball-receiving surface that is elongated in its transverse direction “T” (generally perpendicular to path of club) relative to its width direction “W” (generally parallel to path of the club). The ball-receiving surface is still slightly cupped to hold the ball, but much of the leading and trailing material is removed compared to conventional tees, for less compression and less resistance to follow-through.

Abstract: A biodegradable golf tee having fertilizer properties and method of making the same. According to a preferred embodiment, the golf tee comprises the combination of bentonite, potassium nitrate, and sodium nitrate that are formed into the configuration of a conventional golf tee. Optionally, sodium nitrate, sand, or a pigment, such as chromium (III) oxide, may further be added. The golf tee is specifically designed to degrade when contacted with water or atmospheric air having a humidity of at least 20% or higher. The biodegradable golf tee may further be modified to include soil modifying agents, such as gypsum, as well as grass seed. The invention further comprises methods for forming the biodegradable golf tees of the present invention.
