  • Patent number: 11628341
    Abstract: A golf-tee mount is an apparatus that easily and effectively secures a golf-tee body into the ground. The apparatus includes golf-tee body, a mountable base, and a plurality of spikes. The golf-tee body upholds a golf ball that is about to be hit and is preferably made of a flexible material. The mountable base stabilizes and attaches the golf-tee body into the ground and allows the golf-tee body to be interchangeable as needed and is preferably made of a rigid material. Furthermore, the mountable base may remain connected with the ground while interchanging the golf-tee body. The plurality of spikes penetrates the ground and allows a user to easily fasten the mountable base, and consequently the golf-tee body, into the ground. The golf-tee body further includes a plurality of finger-receiving grooves that allows the user to better grip the golf-tee body while connecting the golf-tee body with the mountable base.

  • Patent number: 5672118
    Abstract: A golf swing trainer consists of a support base for supporting a vertical shaft, the shaft having a flexible horizontal shaft extending from it and having at its other end a golf tee upon which a golf ball can rest. The horizontal shaft is capable of moving up and down in a vertical direction on the vertical shaft and remains relatively fixed to the vertical shaft by a suitable means. A player would practice using the golf swing trainer by hitting golf balls placed on the tee, initially when the horizontal shaft is at a high position relative to the support shaft, and when the player become adept at hitting the ball at the high position, the horizontal shaft would gradually be lowered, so that the player would be hitting the ball at lower and lower positions. This promotes the proper swing plane for the golf swing.
