Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tee-up device for a golf ball in a driving range and a tee device for a tee elevating device.

[0002]

2. Description of the Related Art In golf courses, shots are usually taken up except for short holes. Some people take up in the short hall. This is because the ball can be lifted from the ground and hit, so that a shot can be easily made. In the golf practice range, a golfer must put a ball on the tee each time a tee shot is performed, and the golfer repeatedly bends his waist, which may be troublesome.

[0003] Therefore, a device that automatically tees up a ball, that is, an automatic tee-up device has appeared, and has recently been introduced into a newly established golf driving range. In this automatic tasting device, the supply of the balls and the tasting are linked, so that all the balls are tasted. However, the practice of the take-up shot is only performed when using a wood club, mainly a driver (No. 1 of wood). You don't have to be taed up because you hit the ball on the mat.
Therefore, the shot is performed by dropping the tasted ball onto the mat at the club.

[0004] The ratio of the shot on the mat and the shot on the mat, that is, the shot by the driver and the shot by the club other than the driver, depends on the level of progress of the golfer, the purpose of practice, and individual differences. ,
It seems that there are fewer tee shots. If so, the conventional tasting device does the tasting without the necessity of the tasting, so that wasteful power is consumed.

[0005] The conventional automatic take-up device will be described in more detail. The ball is supplied through an underground pipe on the batting floor, and the ball is placed on an automatic elevating tee and rises on a shot mat. Therefore, such an automatic tee-up device must bury a ball delivery pipe and a tee elevating device underground.
The installation of such a device is a large-scale construction, which is to be carried out systematically before the construction, exclusively in the newly established practice range. With the excavation work, it must be said that it is impossible in terms of cost.

[0006] Next, for the existing practice area,
A ball supply device is installed on the floor in front of the bat, and a ball is carried on the tip of the arm fed from the supply device, carried on the tee, and the operation of changing over the tee is repeated. To change the height of the tee, the golfer generally selects a tee having a different height prepared in advance and replaces the tee with a mat.

[0007] In place of a fixed height tee, there is an automatic tee raising / lowering device buried on the floor below the mat, and the height of the tee can be selected by a button operation. In transferring the ball to this device, the golfer himself puts the ball from a ball lending machine into a basket or the like and carries the ball into a bucket of a ball supply device.

[0008]

In a conventional golf driving range, the installation of the automatic tee raising / lowering device of the tee-up device is performed by digging the floor and embedding the device. The area and depth of the part to be lowered are both large,
There was a drawback that the construction cost increased due to the deepening and the recruitment at the existing practice range. Since the embedded automatic lifting and lowering device incorporates a motor and electrical components, drainage pipes are buried toward the outside of the bat for drainage treatment of rainwater blown during heavy rain, further increasing construction costs. The increase was inevitable. Also, when the ball is shot up with a tee up, the hole of the shot mat is deformed due to the sharp bend of the tee, so the cycle of replacing the shot mat is shortened, the tee itself is consumed quickly, and it is uneconomical. there were.

The present invention has been improved to solve the above-mentioned conventional problems. It is an object of the present invention to provide a golf ball tee elevating device at an existing golf driving range, which can be used on a floor. With as little work as possible,
In addition to reducing construction costs, it also prevents failures caused by rainwater, etc., and makes it easy to set the golf ball's take-up height to a desired height when hitting a shot, and furthermore, the hole of the shot mat To prevent edge deformation.

[0010]

In order to achieve the above object, according to the present invention, in the installation of a tee elevating device at a golf driving range, a tee elevating device portion which is installed by digging down the floor is mechanical. It is composed of only parts, and the electric drive unit that incorporates the motor and electric parts that drive the tee lifting device is installed on the floor, and the power transmission between these electric drive units and the tee lifting device is on the floor. Are linked by a sliding flat plate, thereby reducing equipment costs and reducing damage to the apparatus by rainwater.

That is, the present invention provides a configuration in which a golf ball is guided by a club head into a tee hole provided in a shot mat, the ball is detected by an optical sensor, the tee is raised, and the tee is raised. Take
A tee-up device using an optical sensor and a tee elevating device that selects the height position of the golf tee are installed side by side, and the tee is moved to the highest and lowest positions by the rotation of the tee elevating motor by the optical sensor. It is configured to repeat the raising and lowering movement of the tee by the adjustment motor, and in taking the tee to the lowest position, the tee is dropped by its own weight of the lifting device, or by extension of the spring, The tee lifting / lowering device that repeats the lifting / lowering movement of the tee is configured to be operated by the operation time of a switch of a tee height adjusting motor. In addition, the tee lifting / lowering device section composed of only mechanical parts is installed below the floor surface, and the electric drive section for operating the other tee lifting / lowering device sections is installed on the floor surface. The transmission of power to the side is performed by sliding a flat plate on the floor, so that damage due to rainwater or the like is eliminated. Furthermore, in the tee lifting device using an optical sensor, the lifting through hole of the lifting tie drilled in the lifting tee holding plate below the shot mat has a configuration in which the upper edge of the through hole is rimmed.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A tee elevating device for a golf ball at a driving range according to the present invention comprises a tee elevating device side and an electric drive side for operating the tee elevating device. The electric drive side is installed on the floor, respectively, and the power transmission between the two is performed only by a flat plate sliding on the floor, and the tee elevating unit is composed of only mechanical parts. Therefore, even if rainwater enters, the operation is hardly affected.

In the installation work of the apparatus of the present invention at an existing golf driving range, when the tee elevating device is buried in the floor surface, the floor surface is dug down, for example, in a road pavement work or a concrete work. Drilling can be easily performed by performing core boring, which is a method of collecting water. According to this method, it can be easily installed on the bat floor on the second floor or the third floor. The electric drive unit incorporating the motor and electric parts is installed on the floor, and the flat plate that transmits power between the electric drive unit and the tee lifting device only slides on the floor. You don't need to dig down.

According to the present invention, the golf tee elevating device can be easily installed in the existing driving range by simply drilling a hole for burying the tee elevating device on the bat floor. Can be installed even on the second floor at bat and the third floor at bat.
Installation costs can be reduced.

When a shot is taken with a driver, the golf ball is guided by the golf club onto the tee hole of the shot mat, and the ball is detected by the optical sensor. be able to. Also, when changing the position of the height of the tee-up, by pressing the switch plate with the golf club, release the pressing of the switch plate at the desired height position for the tee that repeats ascending and descending. As a result, the tee stops at that position, so that the height of the tee can be easily set. Once the height of the tee is set, the subsequent tee-up of the ball will always be at the set position, so the player has to turn over the shot mat and replace it with another tee as before. No, you can always shoot in good condition.

Further, when the ball on the elevating tee is shot, a lifting / lowering tee holding lid for preventing the lifting / lowering tee portion from being lifted up and coming off by the impact is provided with a hole on the upper surface side of the through hole through which the lifting / lowering tee is raised and lowered. Since the part is rimmed, this rim part can prevent sudden bending of the elevating tee due to shots, and thus prevent deformation of the shot hole of the shot mat on the elevating tee holding lid. Thus, the position of the lifting tie can be prevented from being shifted, and the detection by the optical sensor can be always ensured. Also, wear of the lifting dies can be prevented. Therefore, it is possible to suppress the advance of the cycle of the exchange of the shot mat and the advance of the exchange due to the consumption of the elevating ties.
