In detail, an outer wall is formed on the inner surface of the fixed pipe 230, an inner wall is formed on the outer surface of the actuating block 250, a detachment prevention plate 240 which intercepts a lower portion of the outer wall, A space for inserting the restoring spring 220 is formed between the inner wall and the outer wall, and a screw groove 255, which is screwed with the screw 150, is integrally formed on the inner side of the inner wall. Structure.

A lifting plate 210 is coupled to an upper portion of the restoring spring 220. The lifting plate 210 is engaged with an upper frame C which is to be inclined in the golf practice plate of the present invention.

Mats M1 and M2 are mounted on the upper portion of the upper frame C and upper portions of the mats M1 and M2 are where the golfer stands.

As will be described later, the restoring spring 220 must have a certain length and elasticity because the load and the tilt are transmitted from the upper frame C to the restoring spring 220 due to the above-described structure.

The inner diameter of the fixing pipe 230 should be set so that the horizontal flow of the restoring spring 220 is limited within a range that does not hinder the restoring force and the elastic force of the restoring spring 220.

At this time, the length of the fixed pipe 230 should be set in consideration of the shock transmitted to the restoring spring 220 or the warp when the tilting is implemented.

3 and 7, a balancing plate 500 is installed on an upper portion of the balancing module B, and the balancing plate 500 is disposed on the upper side of the balancing module B, The balance module B is mounted on the base frame F as a structure to be coupled with the upper frame C. [

3, the lower end of the balance spring 520 is fixed to the base frame F. As shown in Fig. The upper end of the balance spring 520 is configured to be in contact with the horizontal portion of the balance plate 550 so that the elastic force of the balance spring 520 is transmitted to the balance plate 550.

The balancing plate 550 extends at a suitable height in the height direction, that is, vertically upward, and the upper end thereof is joined to the horizontal plate 530 having a generally horizontal shape.

8 is an exploded perspective view of a tilt adjusting means applied to the balance module B according to the present invention.

As shown in FIG. 8, the present invention includes inclination adjusting means, which selectively include a horizontal support rod 520 and the following components.

The lower end of the horizontal support rod 520 penetrates through the horizontal plate 530 and extends downward to be coupled with the plate 525 to prevent the balance plate 500 from being detached due to inclination adjustment or excessive impact.

The upper end, which is one end of the horizontal support rod 520, is coupled with the balance plate 500 having a relatively large horizontal area after passing through the spacer 510. At this time, it is simple that the horizontal support rod 520 has a circular cross section, and a circular through hole 535 corresponding to the circular cross section of the horizontal support rod 520 is placed in the horizontal plate 530.

The through holes 535 passing through the horizontal plate 530 maintain a constant clearance corresponding to the diameter of the horizontal support rods 520. [

A horizontal gap between the horizontal support rods 520 is set so that the horizontal support rods 520 can move horizontally around the through holes 535 passing through the horizontal plate 530. The horizontal support rods 520 coupled with the horizontal plates 530 are moved up and down It has up and down clearance that can move.

The above-described flow gap and upper and lower gap of the horizontal support rod 520 together with the height and diameter of the spacer 510 cause the balance plate 500 coupled with the upper frame C to be inclined and naturally slope in various directions Can be implemented.

Vertical portions extending in the height direction of the balance plate 550 are attached to the rotors 555 that extend in mutually symmetrical shapes so as to rotate at both ends.

At this time, the outer diameter of the rotor 555 is located at the outer portion of the end portion of the balancing plate 550, so that no interference is generated in the rotational motion of the rotor 555.

A slider 590 which is in contact with the rotor 555 is further vertically upwardly disposed on the base frame F. The surface of the slider 590 is provided with The electrons 555 are in contact with the outer circumference of the circumference of the rotor 555 at an interval at which the electrons 555 can flow vertically up and down.

Therefore, since the rotor 555 flows on the surface of the slider 590, the length in the vertical direction has a constant height in accordance with the movement of the rotor 555, and the surface state is a rotational movement of the rotor 555 It is a smooth flat state considering.

The flat plate 530 is formed of at least three pieces of the balance plate 550 and the slider 590 and has a polygonal structure when viewed from the inside of the balance module B. [

The balancer 550 having the rotor 555 attached thereto is disposed on each line of the polygon while the portion where each slider 590 is disposed is a vertex of the polygon. So that the plane shape of the balance module B is arranged to take the form of a closed figure such as a triangle or a quadrangular pentagon.

The other components of the balance module B are located in the inner space of the slider 590 on the basis of the slider 590 provided on a portion corresponding to the corner of the polygon which is the closed figure described above.

The balancer spring 520 is supported under the balancer plate 550 and has a resilient force so that the rotor 555 disposed at both ends of the balancer plate 550 is positioned on the outer side of the slider 590 And is vertically movable along the surface.

In addition, the balance plate 500 located above the balance module B is coupled with the upper frame C.

The reason why the balance module B has such a polygonal configuration is that a plurality of rotors 555 disposed on the balance plate 550 flow inside the slider 590 as described later, C as a restoring force of the balance spring 520 by maximally utilizing the compressive force due to the load transmitted through the balance spring 520. [

The balance module B coupled to the upper frame C with the above restoring force minimizes an anomalous operation caused when the upper frame C is inclined, thereby maximizing the user's sense of security.

This is because, in this embodiment, the shape of the balance module B is selected as a rectangular shape because the convenience of implementation is maximized. That is, if the entire flat surface of the balance module (B) is formed in a rectangular shape, since the entire parts are mostly vertical, the manufacturing is relatively easy and the measurement of the operating error is simple.

The restoring spring 220 and the balance spring 520 must have elasticity and restoring force to return to the original shape when a compressive force is applied according to the load transmitted through the upper frame C, It is preferable that the upper surface and the lower surface are formed in a horizontal state as flat as possible so that they can stand upright in a vertical state when standing on the ground surface.

The spring restoring forces applied to the restoring spring 220 and the balance spring 520 are appropriately selected according to the size of the upper frame C, the application position of the driving body P, the applicable amount of the balance spring 520, .

9 and 10, an operation of the upper frame C including the mats M1 and M2 through the operation of the driving body P will be described in detail.

As shown in FIG. 9, the driving body P is in a lowered state, and the 'golf practice plate' of the present invention is in a horizontal state, and the upper frame C is also in a horizontal state.

In the present embodiment, four driving bodies P are provided on the driving base 300 at the corners of the base frame F and the driving base 300 is coupled to the base frame F.

The guide plate 260 installed in the drive base 300 maintains the vertical state of the guide shaft 290 and the guide plate 260 integrated with the operation block 250 is passed through the guide shaft 290, The lifting unit 200 including the actuating block 250 is guided upward according to the guidance of the lifting unit 290.

At this time, when the motor 100 installed on the driving base 300 rotates, the screw 150 starts to rotate by the rotational force of the motor 100 and is screwed through the screw 150 by the screw 150 The actuating block 250 is moved upward and the lifting part 200 is moved upward as the actuating block 250 moves.

When the motor 100 stops operating, the screw 150 also stops operating, and the elevating portion 200 stops with the operating block 250. This state is a state in which the lifting unit 200 is moved a certain distance.

10 shows a state in which the lifting unit 200 is moved by a predetermined distance and the lifting unit 200 including the lifting unit 250 is lifted up by a predetermined distance in accordance with the vertical upward movement of the lifting unit 250 As shown in FIG.

The recovery spring 220 is mounted on the lifting part 200 and the lifting plate 210 is positioned on the upper end of the restoring spring 220. The lifting plate 210 is further provided with the upper frame C, So that one side of the rectangular upper frame C rises and the inclination of the upper frame C changes as a whole when the elevating part 200 moves upward by a certain distance.

In this operation example, since the horizontal state in which the upper frame C is not inclined is assumed, the above operation is possible.

The lifting plate 210 coupled to the upper frame C also has a slope in parallel with the upper frame C when the lifting part 200 ascends a certain distance and the upper frame C is inclined.

As described above, the restoration spring 220 is supported by the detachment prevention plate 240 and the flow of the restoration spring 220 in the horizontal direction is limited by the fixed pipe 230 having a predetermined length. Therefore, The restoration spring 220 fastened to the lower portion has an inclination in an oblique direction of the upper frame C together with the lift plate 210 because of the inherent elastic characteristics of the spring.

When the upper frame C is returned to the horizontal state together with the lifting plate 210, the restoring spring 220 is restored to the horizontal state due to the inherent elastic characteristics of the spring.

The upper frame C is supported by the four driving bodies P seated on the base frame F as shown in FIGS. 2 and 3 and supports the entirely rectangular base frame, The inclination of the base frame F can be produced by varying the elevation height of the elevating part 200 mounted on the elevating part 200. As a result, the inclination of the mat M1 and M2 can be adjusted according to the purpose of the present invention.

Of course, the operation of lowering the lifting part 200 mounted on the driven body P in an elevated state may be performed in the opposite direction to the lifting operation.

The operation of the balance module B will now be described in detail with reference to FIGS. 9 and 10 again when the upper frame C including the mat (M1, M2) is inclined through the operation of the driving body P.

The lower part of the balance module B is coupled to the central part of the base frame F and the balance plate 500 is positioned on the upper part of the balance module B, As shown in FIG.

In FIG. 9, all the driving bodies P provided on the base frame F are in a descended state, and the golf practice plate of the present invention is in a horizontal state.

This horizontal state is also the same for the upper frame C, and the balance module B is lowered by the load applied to the upper frame C and is in a horizontal state.

At this time, the balance spring 520 is in a state of being compressed by the load of the upper frame (C). Therefore, the selection of the length and elastic force of the balance spring 520 is important.

The length when the balance spring 520 is compressed to the maximum is the time when all the driving bodies P have moved to the lowermost portion and the length of the balance spring 520 is set such that the balance module B deforms the base frame F and the upper frame C It should be a length that does not induce.

The length when the balance spring 520 is maximally stretched is when all the driving bodies P having four corners on the base frame F are moved to the uppermost position, The spacing space should be provided between the ball springs 520 and the ball springs 520 so that the ball springs 520 do not extend beyond the initially produced length.

The balance module B is a structure in which a separate power source is not built and flows when the upper frame C is inclined by the operation of the driving body P having the power source of the motor 100. [

The balance spring 520 which is a component of the balance module B supports the balance module B under the balance plate 550 and is compressed in accordance with the flow of the upper frame C As shown in Fig.

When the driving body P operates in a state in which the upper frame C and the balance module B in Fig. 9 are horizontal, the upper frame C in the state of Fig. 10 and the balance plate 500 in the balance module B ) Changes in a state having an inclination.

10 is a state in which the lifting part 200 of the driving body P rises and the upper frame C is inclined so that the balance plate 500, which is a component of the balance module B, The inclination is changed in accordance with the inclination change of the inclination.

The change in the balance module B when the inclination of the upper frame C changes is as follows.

When the inclination of the balance plate 500 and the upper frame C is varied, the height of the horizontal support bar 520 changes along with the balance plate 500, The balance plate 500 can be changed in inclination since the flow gap and the upper and lower gap of the support rod 520 and the height and diameter of the spacer 510 work together.

At this time, four balance plates 550 are attached to the horizontal plate 530 located below the horizontal support rods 520 and the compressed balance spring 520 is pressed against the balance plate 550 by the elastic force at the lower portion of the balance plate 550, (550).

The rotor 555 at both ends of the balancing plate 550 moves along the surface of the slider 590 located outside the rotor 555 and the horizontal plate 530 coupled with the balancing plate 550 is detached from the outside So that the elastic force of the balance spring 520 is sufficiently transmitted to the balance module B.

The balance module B is configured to move vertically up and down and is coupled to the center of the upper frame C so that the balance module B fixes the overall position of the upper frame C, As shown in Fig.

That is, when the upper frame C is inclined, the load of the upper frame C may be exerted on one side of the upper frame C, Prevent the phenomenon that the upper frame C is detached from the center.

In the present invention, at least two motors 100 are simultaneously driven so that the upper frame C has an inclination. In this case, When the speed difference of the driven motor 100 is generated, the upward and downward movements of the upper frame C become unstable, which causes the user on the mat (M1, M2) to feel uneasy.

However, the restoring spring 220 applied to the present invention is in a state of being compressed to a certain degree by the load of the upper frame C and the mats M1 and M2. When the difference in speed of the ascending and descending of the ascending part 200 occurs, The restoring spring 220 is elongated and compensates for the instability due to the speed difference of the motor 100 at the time of the rising and falling of the upper frame C by a certain amount.

Also, the balance spring 520 is configured in the balance module B, the balance module B is coupled to the center of the upper frame C, and the balance spring 520 partially absorbs the load of the upper frame C The balance spring 520 plays a role of auxiliary power and acts to smooth motion of the upper frame C when the upper frame C descends and to smooth motion of the upper frame C when the upper frame C ascends P to assist the driving force of the motor 100. This operation also has a side effect of reducing the anxiety caused by the difference in the rising speed of the lifting part 200 of the driving body P to some extent.

Therefore, the interaction between the restoring spring 220 and the balance spring 520 applied to the present invention minimizes anxiety in the upward and downward movements of the upper frame C.

The present invention may be embodied in other forms without departing from the spirit or essential characteristics thereof, and the scope of the present invention is indicated by the appended claims, and the present invention is not restricted by the specification. Modifications and variations falling within the scope of the appended claims all fall within the scope of the present invention.
