Abstract: A golf tee made by over molding process that has a softer upper flexible portion and a stiffer lower spike portion. The upper flexible portion and the lower spike portion are joined together at a joining point where two different stiffness materials can come together. With the over molding process, strong mechanical interlocks may be formed while using two different materials as well as using various mixture of a same material having two different stiffness.

Abstract: This invention relates to a golf tee extender of a simple but effective structure for repetitive tee shots that does not require re-inserting a new tee into the ground. The golf tee extender for repetitive tee shots comprises a ball support portion for receiving a golf ball thereon, an upper opening for allowing insertion of a golf tee, a hollow body for allowing passage of the golf tee, and a tee head chamber for engaging head of the golf tee therein and securely confining and holding head of the golf tee. The tee head chamber is configured in a shape reverse to the shape of the head of the golf tee to securely engage and confine the head of the golf tee. The tee head chamber comprises a middle opening and a lower opening wherein the middle opening is smaller in diameter than the head of the golf tee.

Abstract: The nasal catheter system will provide an improvement over existing devices that do not fill the recesses of the nose, do cause significant pain and still do not stop nosebleeds very effectively. The objectives are achieved through the design of a version of the device that has two inflatable bags, which in the preferred embodiment are not elastic balloons. The anterior bag is much larger in volume than the anterior nasal cavity. The design of the bag is generally cylindrical but has deep ridges projecting outward producing a “pleated” design with ribs running along and parallel to the axis of the catheter. Alternate designs include a circumferential ring or capillary tube fingers projecting outward. Any surface projection that serves to create additional surface area or any projection that winds and flows into the meatus recesses of the nasal cavity with greater ease will accomplish some aspect of the desired objective.
