Slope indicator
A slope indicator for fastening to the ground of a putting green to indicate the slope during the game of golf is disclosed to include a housing having a transparent top face and a pointed bottom anchoring rod for fastening to the ground, a fluid sealed in the housing, and a bubble formed in the fluid inside the housing and shifted in the fluid subject to the tilting condition of the housing to give an indication of the slope of the ground to which the slope indicator is fastened.
1. Field of the Invention
The present invention relates to golf gears and more particularly, to a slope indicator for use in the game of golf to indicate the slope of the ground for reference before the player is putting the golf ball toward the hole.
2. Description of the Related Art
When a golf ball is driven to the putting green during the game of golf, a putter shall be used to putt the golf ball toward the hole. At this time, the putting angle and force must be properly controlled so that the golf ball can be accurately putted toward the hole. Because the putting green is a slope ground and the slope of the ground around the location of the golf ball is a critical factor that will affect putting, the player must figure out the slope of the ground before putting the golf ball toward the hole. However, it is difficult to measure the slope of the ground with the eyes without an implement. Therefore, it is desirable to provide a slope indicator practical for use in a putting green to indicate the slope of the ground before putting the golf ball.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a slope indicator, which is practical for use in the game of golf to indicate the slope of the ground for reference so that the player can accurately putt the golf ball toward the hole.
To achieve this and other objects of the present invention, the slope indicator comprises a hollow watertight housing, the housing having a transparent top face and an anchoring member perpendicularly extending from the center of a bottom wall thereof; a fluid filled in the hollow watertight housing; and a bubble formed in the fluid inside the hollow watertight housing and positioned in the center in the fluid when the hollow watertight housing is kept in horizontal, the bubble being deviated from the center in the fluid to a deviated position in the fluid when the hollow watertight housing is tilted.
Further, the anchoring member has a bottom opening in communication with the inside space of the hollow watertight housing through which the fluid is filled in the hollow watertight housing, and a sealing ball sealed to the bottom opening to stop the fluid inside the hollow watertight housing.
Further, the anchoring member is a pointed rod member for fastening to the ground.
Referring to
During fabrication of the slope indicator 100, a fluid 2 is filled through the opening 111 of the pointed anchoring member 11 into the inside of the housing 1, and a ball 3 is inserted into through the opening 111 into the inside of the pointed anchoring member 11 and bonded to the inside wall of the pointed anchoring member 11 at a location about 1.5˜2.5 mm from the opening 111 by ultrasonic sealing. Thereafter, the opening 111 of the pointed anchoring member 11 is sealed with a sealing groove to prohibit leakage of the fluid 2. When the slope indicator 100 is made, a bubble 21 is in presence in the fluid 2 inside the housing 1 and visible from the outside through the transparent top face 12. By means of the pointed anchoring member 11, the slope indicator 100 can be fastened to the ground of the putting green so that the user can determine the slope of the ground of the putting green subject to the location of the bubble 21 in the fluid 2 inside the housing 1 before putting the golf ball into the hole.
Referring to
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
Claims
1. A slope indicator comprising:
- a hollow watertight housing, said housing having a transparent top face and an anchoring member perpendicularly extending from the center of a bottom wall thereof;
- a fluid filled in said hollow watertight housing; and
- a bubble formed in said fluid inside said hollow watertight housing and positioned in the center in said fluid when said hollow watertight housing is kept in horizontal, said bubble being deviated from the center in said fluid to a deviated position in said fluid when said hollow watertight housing is tilted.
2. The slope indicator as claimed in claim 1, wherein said anchoring member has a bottom opening in communication with the inside space of said hollow watertight housing through which said fluid is filled in said hollow watertight housing, and a sealing ball sealed to said bottom opening to stop said fluid inside said hollow watertight housing.
3. The slope indicator as claimed in claim 1, wherein said anchoring member is a pointed rod member for fastening to the ground.
