Description

A golf putting practice device Technical Field

[0001] This invention relates to the field of golf training equipment technology, and more particularly to a golf putting practice device. Background Technology

[0002] Golf, a sport that combines enjoying nature, physical exercise, and recreation, has gained increasing popularity in recent years. Among the various techniques in golf, putting is the key to determining the final score. To facilitate practice for golf enthusiasts indoors or off-course, various golf putting practice machines have emerged on the market. Existing golf putting practice machines typically consist of a putting green, a return track, and a ball catcher at the end. The main function of these machines is to provide a flat surface for users to practice the accuracy and power control of their shots, using a mechanical or gravity-based return mechanism to automatically return the ball to its correct position, thereby improving practice efficiency.

[0003] Existing golf putting practice devices have shortcomings in simulating real-world putting environments. In actual golf courses, the greens are rarely perfectly level; they typically feature complex undulations and varying slopes, demanding high levels of strategic thinking and power control from the putter in non-level conditions. However, most putting practice devices on the market currently only offer a single level putting mode, and their end-of-course putter boxes are usually fixed, making it difficult to adjust the tilt angle. This structural limitation prevents the products from simulating complex terrain such as uphill, downhill, or side slopes common on real courses, forcing consumers to engage in mechanical training on a single plane, lacking the realistic simulation of dealing with varying terrain.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides a golf putting practice device to solve the technical problem that existing putting practice devices cannot adjust the slope due to the fixed position of the putting box, making it difficult to simulate the complex terrain of a real green for users to conduct practical training.

[0006] The present invention adopts the following technical solution: a golf putting practice device. The system includes a main frame comprising sidewall panels on both sides and a bottom support rod connecting the bottom of the two sidewall panels, the front end of which is pivotally connected to the sidewall panels; a ball box assembly located at the rear of the main frame, comprising a putter panel positioned between the sidewall panels and a reinforcing plate connected between the sidewall panels, the putter panel having a hole, and a ball guide plate connected below the putter panel; a putter mat laid on the surface of the putter panel and extending forward; a return track assembly connected to one side of the ball box assembly for guiding a golf ball entering the hole back; a ball guide structure on the side of the sidewall panel, the ball guide structure communicating with the return track assembly for guiding a golf ball falling into the hole to the return track assembly; and a slope adjustment mechanism located below or behind the ball box assembly for changing the height of the rear end of the putter panel relative to the front end, causing the putter panel to rotate around its front pivot point, thereby adjusting the tilt angle of the putter panel.

[0007] Furthermore, the ball guiding structure includes a ball outlet formed on the side of a set of sidewall baffles, and a ball guiding base plate disposed below the pusher panel, the ball guiding base plate guiding the ball to the ball outlet; the ball box assembly also includes a rear baffle vertically fixed to one side of the ball guiding base plate; the return ball track assembly includes a near-end return ball track that connects to the ball outlet; a ball guiding groove formed on the near-end return ball track, and a middle return ball track, a far-end return ball track and an end baffle connected in sequence, the far-end return ball track also having a ball stopping groove.

[0008] Furthermore, the putter panel consists of two inclined plates with a gap of 55mm between its side and the rear of the main frame, which is larger than the diameter of a standard golf ball. The putter panel has a first hole and a second hole, with the first hole having a diameter of 90mm and the second hole having a diameter of 65mm.

[0009] Furthermore, the slope adjustment mechanism is used to drive the side wall baffles on both sides to rotate the entire push rod panel around the pivot axis. The slope adjustment mechanism includes a rotating baffle rotatably disposed between the rear ends of the two bottom support rods. A metal groove plate is fixed on the inner side of the rotating baffle. The metal groove plate is provided with a number of metal slots spaced apart in the vertical direction. A U-shaped metal strip is fixed on the outer side of the rear baffle. By rotating the baffle outward, the U-shaped metal strip is engaged in the metal slots at different heights, thereby locking the slope of the push rod panel.

[0010] Furthermore, the slope adjustment mechanism also includes a transmission mounting base fixed on the reinforcing plate. The transmission mounting base has a sliding groove, and a lead screw is mounted on a bearing in the sliding groove. One end of the lead screw is connected to an adjustment handle that passes through a set of side wall baffles. The sliding groove has a sliding seat that is threadedly engaged with the lead screw. Rotating the adjustment handle drives the sliding seat to move in a straight line, thereby lifting the push rod panel through the mechanical transmission assembly.

[0011] Furthermore, the mechanical transmission assembly includes a horizontal support fixed to the side of the sliding seat and moving therewith. The horizontal support is provided with an inclined slide rail, and an arched frame is slidably arranged on the inclined slide rail. Several guide columns are fixed on the reinforcing plate, and the several guide columns are arranged through the arched frame. The top of the arched frame is provided with a support rod suitable for abutting the bottom of the push rod panel. When the horizontal support moves horizontally, the inclined slide rail forces the arched frame, which is restricted by the guide columns, to rise and fall in the vertical direction, thereby driving the support rod to lift the push rod panel.

[0012] Furthermore, a rotating shaft is fixed to the inclined bottom end of the push rod panel. The two ends of the rotating shaft extend into the receiving holes of the side wall baffles. The slope adjustment mechanism drives the push rod panel to rotate around the rotating shaft. A torsion spring is sleeved on the rotating shaft to keep the push rod panel under downward pressure. The slope adjustment mechanism also includes a rotating baffle that is rotatably disposed between the rear ends of the two bottom support rods via the torsion spring. The torsion spring is configured to keep the rotating baffle always rotating towards the push rod panel. A slope plate is fixed to the inner side of the rotating baffle. The surface of the slope plate is provided with several locking slots. Adjacent locking slots form locking grooves. A locking rod is provided on the baffle at the rear of the push rod panel. When the support rod lifts the push rod panel to adjust the slope, the locking rod engages with the corresponding locking groove to achieve locking.

[0013] Furthermore, the sidewall baffle has a vertically adjustable groove on its side. The ball guide structure is specifically a movable ball guide channel. The movable ball guide channel is located below the putter panel. One end of the channel receives the ball falling into the hole, and the other end passes through the adjustable groove and points towards the return ball track assembly. The movable ball guide channel is adapted to slide along the adjustable groove as the putter panel rises and falls, ensuring continuous connection.

[0014] Furthermore, the bottom side of the main frame is also provided with an external support component for raising the overall height to assist in adjusting the slope. The external support component is one of the following structures: a knob-type adjustable foot, which achieves height adjustment by rotating a knob; a plate-type support foot, which is a plate-shaped bracket with a fixed height; a foldable support foot, which includes a foldable support plate; a friction-type stepless adjustable foot, which achieves stepless suspension by connecting a damping adjustment plate through a damping pivot; or a gear limit support frame, which includes a gear adjustment base plate and a limit support rod.

[0015] Furthermore, the putter mat is made of short nylon fibers on the surface and TPR rubber on the bottom through high-temperature hot pressing. The friction coefficient of the short fibers is configured to simulate the rolling resistance of a real golf course lawn. The inclined design of the putter panel ensures that the ball can roll naturally.

[0016] The above-mentioned at least one technical solution adopted in this invention can achieve the following beneficial effects:

[0017] A golf putting practice device features a pivot shaft at the front of the base support and a slope adjustment mechanism located below or behind the ball box assembly. This mechanism alters the height of the putter face's rear end relative to the front end, driving the putter face to rotate around a pivot point at the front end. This allows for flexible adjustment of the putter face's tilt angle, simulating green environments with varying slopes and overcoming the limitations of traditional practice devices with only one slope. Simultaneously, a ball guide structure on the side wall baffles and a return track assembly connected to one side create a continuous path from the hole through the side to the external track, enabling automatic ball retrieval and eliminating the need for frequent ball collection, thus improving practice efficiency. Furthermore, a reinforcing plate connecting the two side wall baffles enhances the overall connection strength and structural rigidity of the components, ensuring stability during slope adjustment and use.

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0038] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1:

[0040] Referring to Figures 1-3 and 11-15, the present invention provides a golf putting practice device, which mainly consists of a main frame 1, a ball box assembly 2 installed at the rear of the main frame 1, a putting mat 3 laid on the surface, a return track assembly 4 connected to one side, and a slope adjustment mechanism for adjusting the slope.

[0041] The main frame 1 consists primarily of two symmetrically arranged side wall panels 11 and a bottom support rod 12 connected to the bottom of the two side wall panels 11. The side wall panels 11 form the mounting base for the main body's exterior appearance and internal structure, while the bottom support rod 12 serves as the ground contact component, ensuring stability. To enable subsequent overall angle adjustment, the side wall panels 11 and the bottom support rod 12 are not completely rigidly fixed, but rather employ a rotating connection structure. Specifically, the front end of the bottom support rod 12 is hinged to the front end of the side wall panel 11 via a pivot shaft 121, allowing the side wall panel 11 to open, close, or rotate relative to the bottom support rod 12 at a certain angle around the pivot shaft 121.

[0042] To simulate the putting environment of a real green, a ball box assembly 2 is installed between the two side wall panels 11 of the main frame 1. The ball box assembly 2 includes a putter panel 27, which is embedded between the inner sides of the two side wall panels 11. To meet the training needs of different difficulty levels, the putter panel 27 has holes, specifically a first hole 271 and a second hole 272. The diameter of the first hole 271 is preferably 90mm, and the diameter of the second hole 272 is preferably 65mm. To prevent balls that do not enter the hole from getting stuck, the putter panel 27 is composed of two inclined plates. The inclined design of the plate surface ensures that the ball can roll naturally. A gap is reserved between the side of the putter panel 27 and the rear of the main frame 1. The width of this gap is preferably 55mm, which is larger than the diameter of a standard golf ball, so that balls that do not enter the hole can also fall smoothly through this gap to the bottom, achieving full path recovery.

[0043] Between the two sets of sidewall baffles 11, in addition to the upper core putter panel 27, there is also a bottom ball guide structure and a rear support structure, which together constitute the complete ball box assembly 2. Specifically, a tilted ball guide base plate 24 is fixed directly below the putter panel 27. This ball guide base plate 24 is tilted backward to receive the falling ball and is also tilted towards the ball outlet 13. It is used to receive all balls falling from the hole and from the side gaps. A rear baffle 25 is vertically fixed upward on the rear side of the ball guide base plate 24. The putter panel 27, the ball guide base plate 24, and the rear baffle 25 are fixed relative to the sidewall baffles 11 on both sides, forming a movable frame structure with a constant internal relative position. When the slope is adjusted, this frame structure rotates as a whole around the pivot axis 121 without affecting the connectivity of the internal ball guide passage. In addition, to enhance the structural rigidity of the bottom, a fixed reinforcing plate 28 is connected between the two bottom support rods 12.

[0044] In this embodiment, to achieve stable locking after slope adjustment, the slope adjustment mechanism is located at the rear of the ball box assembly 2. The specific structure is as follows: A U-shaped metal strip 26 is horizontally fixed on the outer side of the rear baffle 25, i.e., the side facing away from the ball hole. The U-shaped metal strip 26 rises and falls with the ball box assembly 2 as a whole. Secondly, a rotating baffle 21 is rotatably arranged between the rear ends of the two bottom support rods 12. A metal groove plate 22 is fixed on the inner side of the rotating baffle 21 facing the ball box assembly 2. The metal groove plate 22 is provided with a number of metal slots 23 spaced apart in the vertical direction. Each metal slot 23 corresponds to a preset slope height.

[0045] The adjustment principle is as follows: when the user needs to change the slope of the putter panel 27, he / she manually lifts the rear end of the ball box assembly 2, which drives the rear baffle 25 and the U-shaped metal strip 26 to rise. At the same time, the baffle 21 is rotated outward to lock the U-shaped metal strip 26 into the metal slot 23 at the target height. At this time, relying on gravity and the stability of the triangular support structure, the putter panel 27 is locked at the selected tilt angle, thereby simulating the training effect of greens with different slopes.

[0046] In this embodiment, in order to cooperate with the fixed ball guide path, the ball guide structure includes a ball outlet 13 opened on the side of the side wall baffle 11. The ball falling into the hole falls onto the ball guide base plate 24 and is guided by the ball guide base plate 24 to slide towards the ball outlet 13 under the action of gravity. In order to realize the automatic recovery of the ball, the ball return track assembly 4 is connected to one side of the ball box assembly 2. Specifically, the ball return track assembly 4 includes a near-end ball return track 41 that is connected to the ball outlet 13 and a ball guide groove 42 opened on the side of the near-end ball return track 41. After the ball rolls out of the ball outlet 13, it is guided by the arc of the ball guide groove 42 and smoothly enters the straight track path. Then it passes through the middle ball return track 43 and the far ball return track 44 that are spliced ​​and extended in sequence, and finally reaches the end baffle 46. The far ball return track 44 is also provided with a ball stop groove 45 to prevent the ball from rolling out of the end of the track.

[0047] To provide a realistic putting feel, a putting mat 3 is laid on the surface of the putting panel 27 and extends forward. The putting mat 3 is made of short nylon pile on the surface and TPR rubber on the bottom through high temperature hot pressing. The friction coefficient of the short pile surface is specially configured to simulate the rolling resistance of a real golf course.

[0048] Example 2:

[0049] To further improve the convenience of slope adjustment, as shown in Figures 4 to 10, based on the above-mentioned partial embodiment one, this embodiment provides an optimized solution using mechanical transmission drive and automatic locking. The core of this embodiment is that the stepless lifting and multi-level stable locking of the push rod panel 27 can be achieved by rotating the adjustment handle, without the need for manual movement of the panel.

[0050] Unlike Embodiment 1 described above, the push rod panel 27 is no longer embedded between the inner sides of the two sets of side wall baffles 11, but is directly in contact with the inner sides of the two sets of side wall baffles 11 to accommodate the sliding friction requirements during lifting. Simultaneously, the rotating baffle 21 initially remains in an upward-flipped state and is rotatably connected to the rear ends of the two bottom support rods 12 via a pivot and a torsion spring (not shown in the figure). This torsion spring is configured to ensure that the rotating baffle 21 always maintains a tendency to rotate towards the push rod panel 27 (i.e., forward), thereby providing a continuous preload force for automatic engagement.

[0051] Specifically, the slope adjustment mechanism 5 is located below the ball box assembly 2. A transmission mounting base 53 is fixed on the reinforcing plate 28 connecting the two bottom support rods 12. The transmission mounting base 53 has a sliding groove 531 inside. A lead screw 54 is rotatably mounted in the sliding groove 531 via a bearing. One end of the lead screw 54 is connected to an adjustment handle 55, which extends through to the outside of a set of side wall baffles 11 for user operation. A sliding seat 56 is threaded onto the lead screw 54. The sliding seat 56 is confined within the sliding groove 531. When the adjustment handle 55 is rotated, the lead screw 54 rotates, driving the sliding seat 56 to perform horizontal linear reciprocating motion along the sliding groove 531.

[0052] In order to convert the horizontal movement of the sliding seat 56 into the vertical lifting movement of the push rod panel 27, this embodiment is provided with a mechanical transmission component, which is connected between the sliding seat 56 and the push rod panel 27. Specifically, the mechanical transmission assembly includes a horizontal support 57 fixed to the side of the sliding seat 56 and moving with it. The horizontal support 57 moves synchronously with the sliding seat 56, and its upper surface is provided with an inclined slide rail 571. At the same time, several guide columns 59 are vertically fixed upward on the reinforcing plate 28, and an arched frame 58 is slidably arranged on the inclined slide rail 571. The guide columns 59 are arranged through the arched frame 58, thereby restricting the arched frame 58 to move only in the vertical direction, that is, restricting its horizontal displacement. Several support rods 510 are fixedly provided on the top of the arched frame 58. The top of the support rods 510 abuts against the bottom of the push rod panel 27. When the horizontal support 57 moves inward with the sliding seat 56, the inclined slide rail 571 in the mechanical transmission assembly forces the arched frame 58, which is restricted by the guide columns 59, to climb upward along the inclined surface, thereby smoothly lifting the rear end of the push rod panel 27 through the support rods 510.

[0053] A rotating shaft 241 is fixed at the inclined bottom end (i.e., front end) of the push rod panel 27. Both ends of the rotating shaft 241 extend into the receiving holes on the inner side of the side wall baffles 11, allowing the push rod panel 27 to rotate around the shaft. To ensure that the panel can fit tightly against the support rod 510 during downward adjustment, a torsion spring 242 (see enlarged view in Figure 6) is sleeved on the rotating shaft 241. Both ends of the torsion spring 242 abut against the side wall baffles 11 and the push rod panel 27, respectively, continuously applying a torque to reset the push rod panel 27 downward.

[0054] Thanks to the initial state setting of the rotating baffle 21 described above, this embodiment achieves automatic locking. A slope plate 51 is fixed on the inner side of the rotating baffle 21. The surface of the slope plate 51 is provided with a plurality of locking groove plates 511 arranged parallel to the side of the slope plate 51 along the inclined direction, and a locking groove is formed between adjacent locking groove plates 511. Correspondingly, a locking rod 251 is fixed on the baffle at the rear of the push rod panel 27.

[0055] The locking process is as follows: when the support rod 510 lifts the push rod panel 27, the latch rod 251 rises accordingly; at this time, since the rotating baffle 21 is always pressed forward by the torsion spring, the latch rod 251 can smoothly slide over the inclined surface of the latching groove plate 511 and automatically engage in the corresponding latching groove to form a mechanical engagement lock and prevent the panel from falling back under pressure.

[0056] Since the pusher panel 27 undergoes height adjustment in this embodiment, a vertically elongated adjustable groove 111 is provided on the side of the side wall baffle 11 to ensure that the ball can be smoothly discharged at any slope. The ball guide structure is specifically designed as a movable ball guide channel 52, located below the pusher panel 27 and directly contacting the ball guide base plate 24. This movable ball guide channel 52 slides through the adjustable groove 111, with its outlet pointing towards the near end of the return ball track assembly 4. When the pusher panel 27 adjusts its slope by raising or lowering, the ball guide base plate 24 fixed below the panel rises and falls synchronously, thereby lifting the movable ball guide channel 52 upwards. Under the push of the ball guide base plate 24, the movable ball guide channel 52 slides vertically along the adjustable groove 111. This structure ensures that regardless of the panel's height, the internal ball drop channel and the external return ball track remain connected, and the movable ball guide channel 52 operates smoothly under the limiting effect of the adjustable groove 111.

[0057] Working principle: When the user needs to increase the slope of the push rod panel 27, they manually turn the adjusting handle 55, which drives the lead screw 54 to rotate within the transmission mounting base 53. The rotation of the lead screw 54 drives the sliding seat 56 and its connected horizontal support 57 to move horizontally in a straight line along the slide groove 531. At this time, the inclined slide rail 571 on the upper surface of the horizontal support 57 moves inward. Since the arched frame 58 is restricted by the guide column 59 and cannot move horizontally with it, under the pushing action of the inclined slide rail 571, the arched frame 58 is forced to slide relative to the inclined surface of the inclined slide rail 571 and rise vertically. The rise of the arched frame 58 drives the top support rod 510 to push the bottom of the push rod panel 27 upward, so that the push rod panel 27 overcomes the resistance of the torsion spring 242 on the front rotating shaft 241 and deflects upward around the rotating shaft 241, thereby steplessly increasing the slope. Conversely, by rotating the handle in the opposite direction, the horizontal support 57 retracts, and the push rod panel 27 descends smoothly against the support rod 510 under the reset pressure of the torsion spring 242 and its own weight.

[0058] Secondly, regarding the automatic locking and stabilizing mechanism during the adjustment process: During the lifting of the push rod panel 27, the latch 251 fixed to the rear of the panel rises synchronously. Simultaneously, under the preload of the bottom torsion spring, the rotating baffle 21 maintains a forward (i.e., towards the push rod panel 27) pressing tendency. When the latch 251 rises past the slope plate 51 inside the rotating baffle 21, it smoothly slides over the inclined surface of the latching groove plate 511. Once the adjustment stops, under the continuous rotational thrust of the rotating baffle 21, the latch 251 automatically engages in the nearest latching groove, forming a reliable mechanical engagement. This structure not only achieves automatic locking similar to a ratchet, but also, in conjunction with the downward pressure applied by the front torsion spring 242, ensures that the push rod panel 27 is clamped tightly at any adjustment height, eliminating loosening and wobbling.

[0059] Finally, regarding the dynamic ball guiding logic under varying slope conditions, as the putter panel 27 rises and falls, the ball guide plate 24 fixed below it also shifts synchronously. Since the movable ball guide channel 52 directly contacts the ball guide plate 24 and slides through the side wall adjustment groove 111, the rise and fall of the ball guide plate 24 directly lifts (when rising) or follows (when falling) the movable ball guide channel 52 under gravity, causing it to slide vertically along the adjustment groove 111. This follow-up design ensures that regardless of the tilt angle of the putter panel 27, the ball falling into the hole can accurately land in the movable ball guide channel 52 and always align with the externally fixed return trajectory assembly 4, achieving continuous communication between the internal displacement mechanism and the external fixed assembly, ensuring smooth ball return.

[0060] Example 3:

[0061] Referring to Figures 11 to 15, in order to further expand the slope adjustment range of the push rod exerciser, or in order to raise one side of the exerciser as a whole without changing the relative angle of the internal push rod panel 27 (simulating the overall side slope), the present invention also provides an external support component on one side of the bottom of the main frame 1.

[0062] Depending on the product positioning and usage scenario, the external support component can adopt one of the following specific implementation structures:

[0063] As shown in Figure 11, a knob-type adjustable foot 6 is provided at the bottom of the main frame 1. This knob-type adjustable foot 6 is mainly used for fine adjustment of height. The knob-type adjustable foot 6 is installed at the bottom of the main frame 1 by means of threaded connection. It includes a large-diameter adjustment knob (not shown in the figure). By rotating the adjustment knob 61, the user can make it move vertically relative to the main frame 1 using the thread transmission principle, thereby changing the height of the base on that side from the ground. It is suitable for leveling uneven ground or simulating slight slopes. This structure is generally the screw-adjustable foot structure commonly found at the bottom of furniture or instruments in the prior art.

[0064] As shown in Figure 12, a plate-type support foot 7 is provided at the bottom of the main frame 1. The plate-type support foot 7 is a simplified structural solution. The plate-type support foot 7 is a block or plate-shaped bracket with a preset fixed height. It is rigidly fixed or detachably installed at the bottom of the bottom support rod 12. This structure is used to provide a stable, non-adjustable fixed elevation angle. This structure is generally a fixed pad or support base structure commonly found in the prior art.

[0065] As shown in Figure 13, a foldable support foot 8 is provided at the bottom of the main frame 1. The foldable support foot 8 includes a support plate (not shown in the figure) pivotally connected to it via a pivot. When idle or training on flat ground, the support plate 81 can be folded and stored. When in use, it is flipped outward to support the ground, thereby instantly raising one end of the main frame 1. This structure is generally a flip support structure of keyboard brackets or folding table legs commonly found in the prior art.

[0066] As shown in Figure 14, a friction-type stepless adjustment foot 9 is provided at the bottom of the main frame 1. This friction-type stepless adjustment foot 9 mainly includes a damping adjustment plate (not shown in the figure) and a damping pivot (not shown in the figure) connecting the plate to the main body. Its working principle is as follows: utilizing the high friction torque inside the damping pivot, the user needs to apply a certain external force to move the damping adjustment plate. Once the force is stopped, the damping adjustment plate overcomes gravity under the action of friction and is stably suspended at the current angle. This structure is generally the damping suspension hinge structure commonly used in the existing technology of laptop hinges or desk lamp joints.

[0067] As shown in Figure 15, a gear position limiting support frame 10 is provided at the bottom of the main frame 1. This gear position limiting support frame 10 mainly consists of a gear position adjustment base plate (not shown in the figure) fixed at the bottom and a movable limiting support rod 110 (not shown in the figure). Its working principle is as follows: the gear position adjustment base plate has several limiting slots of different depths. During adjustment, the user inserts one end of the limiting support rod into different slots, utilizing the stability principle of triangles to rigidly lock the lifting height of the main frame 1.
