Description

Technical Field

[0001] This invention relates to putting devices and systems. In particular, this invention relates to improvements or related improvements to golf practice devices and systems to help golfers improve their putting skills. Background Technology

[0002] Various known putting aids (such as putting mats) allow golfers to practice putting off the course. Some putting aids include features that further help golfers improve their putting technique. For example, known putting aids may include an incline in the course surface to add a difficulty factor when putting.

[0003] Furthermore, some putting aids known in the art include adjustable surfaces. Golfers can adjust the course surface properties of these devices, such as slope, to introduce variable difficulty elements or practice specific putts.

[0004] Some putting aids known in the art provide variable slope by implementing a complex network of mechanical actuators that precisely adjust the contours of the course surface. However, these methods are difficult and expensive to manufacture due to their complexity. They are also difficult to operate, and the fact that they typically require computer control further increases cost and complexity.

[0005] Less complex adjustable putting aids are well known in the art. However, a common problem with these devices is that the simplified mechanisms used to adjust the course surface characteristics of these aids can create localized, steep mounds or "mole mounds" on these course surfaces. This is undesirable because it produces an unrealistic course surface compared to a green on a golf course.

[0006] Therefore, improvements to the adjustable push rod assist device or related improvements are needed. Summary of the Invention

[0007] In one aspect of the invention, a golf practice apparatus is provided, comprising: a support structure including (e.g., in use) two or more panels flexibly connected together to define a course area; a putting layer (e.g., in use) disposed on the course area of ​​the support structure, wherein the putting layer defines a course surface; and one or more inflatable chambers located on the side of the support structure opposite to the course surface, whereby the profile of the course surface can be altered by inflating and deflating the inflatable chambers.

[0008] The inflatable chamber is located on the side of the supporting structure opposite the course surface. Therefore, when the inflatable chamber is adjusted, the changes in the course surface profile (e.g., slope or shape) extend across the lateral areas of the panel, resulting in relatively gentle variations, unlike the locally steep mounds or "mole mounds" that would occur if the inflatable chamber were positioned between the panel and the putter layer. The profile of the putter surface can be described relative to the ground or other surfaces on which the device is positioned. This advantageously allows for the adjustment of slope and undulation in a manner similar to the profile of a green on a golf course. The putter layer also smooths any edges or steps between adjacent panels, creating a realistic course surface.

[0009] A putter layer, positioned (e.g., located) on the course area, defines the course surface for the putting device. In other words, in use, a golf ball is struck to roll on the course surface. The putter layer is typically configured to substantially completely cover the course area. The putter layer can comprise a single layer of material or multiple layers (e.g., multi-layered materials). The putter layer can comprise nylon, felt, artificial turf, or other suitable materials to provide a realistic putting surface. Preferably, the putter layer comprises a nylon layer over a thermoplastic rubber layer. The putter layer is generally flexible to conform to the contours of the support structure. In this manner, as described above, the contours of the course surface can be adjusted by the operation of one or more slope adjustment elements to produce realistic undulations. The putter layer is typically in the form of a putter pad. In use, the putter layer can be configured to be positioned on the course area of ​​the supporting structure.

[0010] The panels of the support structure are flexibly joined together (e.g., flexibly connected) to define the course area. The putter layer is typically positioned to substantially completely cover the course area. The course area defined by the panels is the area of ​​the support structure defined by the top of the panels in use. In other words, the course area has a larger lateral area than the lateral area defined by a single panel. The panels can typically be joined end-to-end (e.g., laterally) in the longitudinal direction to define an elongated course area. An inflatable chamber is positioned below the panels in use, opposite the course surface. In other words, the support structure has a first side defining the course area and an opposing second side, with the inflatable chamber located on the second side. Therefore, when the inflatable chamber is inflated, its corresponding panel tilts, causing its slope to change. This thus changes the slope of the course area and therefore the course surface, as the change in slope is “spread” across the lateral area of ​​the panels. Because the panels are flexibly joined (e.g., flexibly connected), panels adjacent to the active tilting panel can tilt to different degrees than the active tilting panel, thus enabling the creation of realistic multi-planar undulations across the course surface.

[0011] Known assistive devices achieve precise adjustment of the contours of the court surface at many individual locations by adjusting the slope of multiple panels. Unlike known putter assistive devices, the present invention uses a relatively limited number of adjustment points to achieve realistic undulations across the court surface and avoids the problem of producing unrealistic "mole mound" slopes.

[0012] Two or more panels are flexibly connected together. In other words, these panels are not rigidly connected. Thus, the panels can be at least partially hinged to each other independently. The panels can be flexibly connected or joined together via one or more hinges or other suitable connectors to create the flexible connection, such as elastic connections or webbing connections. In some embodiments, the panels can be described as being connected by joints. An advantage associated with including two or more panels flexibly connected together is that the user can create a course surface with variable profiles. For example, the course surface can be adjusted to include “uphill” sections and “flat” sections. Conversely, if only one panel exists in the support structure, or if the panel is rigidly connected, the course surface will only include a profile with a constant slope, which is not typical of a green. However, it should be noted that, if desired, the inflatable chamber of the present invention can be controlled to provide a constant slope for the support structure.

[0013] In a preferred embodiment, two or more panels include a first panel and a second panel, which are flexibly connected together such that the slope of the first panel depends in part on the slope of the second panel. Thus, when the first panel is tilted by actuation of the inflatable chamber, the panel connected to the tilted panel can also be partially tilted, thereby advantageously minimizing local ridges or steps between adjacent panels. In this way, the slope of the second panel depends in part on the slope of the connected first panel.

[0014] Preferably, the panels are flexibly joined together by one or more tension connectors, each of which includes a tension member. In this way, the tension member generates a restoring force against the completely independent hinge action of the panels, such that the slopes of the panels joined using the tension connectors are partially dependent on each other. The restoring force typically pushes the joined panels toward the position where they define a flat surface. Using tension connectors to provide partial dependence on the slopes of the joined panels advantageously means that relatively few inflatable chambers can be used to produce realistic variations in the shape of the court surface. Advantageously, when adjusting the contours of the court surface, the tension is located in the support structure (e.g., the tension member of the tension connector is under tension). This means that there is no need to adjust the tension in the putter layer (e.g., putter pad), as the putter layer is entirely supported by the support structure.

[0015] The strength of a tension member (e.g., the strength of its restoring force) can be selected based on the number of panels present and the degree to which the slope of the panels to be connected depends. Typically, tension members are constructed to generate a restoring force greater than the weight of the panels.

[0016] A preferred example of a tension connection is a tension hinge. Therefore, in a preferred embodiment, the panels are flexibly connected together via one or more tension hinges, preferably wherein each of the one or more tension hinges includes one or more tension members configured to generate a restoring force pushing the tension hinge to an open position. In this embodiment, the panels can be described as hingedly connected.

[0017] When two connected panels define a substantially flat surface, the tension hinge is in the open position. Typically, the hinge's open angle is generally no greater than 180 degrees. When the first panel tilts, the tension hinge connecting the first panel to the (directly) adjacent second panel begins to close. A restoring force overcomes the weight of the second panel, thus causing the second panel to tilt. The tension is selected by one or more tension members such that the second panel tilts less than the first panel, but does not keep the adjacent panel from tilting when the first panel tilts. Preferably, the tension member of the tension hinge (or other tension connection) comprises an elastic cord ("elastic cord") or spring that provides the required tension. The hinge partially closes by inflating an inflatable chamber of one of the panels. The greater the amount of air in the chamber of the first panel, the greater the amount of closure of the hinge.

[0018] In embodiments comprising more than two panels, the orientation of the tension hinges connecting different panel pairs can be varied. For example, one hinge (or set of hinges) connecting the first pair of panels can close in one direction, while another hinge (or another set of hinges) connecting the second pair of panels can close in the opposite direction. This arrangement can be advantageously used to control the degree and manner of hinge on the court surface. In various embodiments, the closing direction of the hinges or hinge groups can alternate for corresponding panel pairs. Furthermore, this allows the panels to be easily folded for compact storage. For example, a hinge group connecting the end panels can close in one direction, while a hinge group connecting the panels in the middle of the support structure can close in the opposite direction to achieve an "accordion-like" fold.

[0019] Tension hinges allow for folding panels to store devices without requiring the removal of the push rod mechanism.

[0020] While not strictly necessary, it is preferred that the panels be generally rectangular (and may be generally square). This geometry allows for the creation of a generally continuous court area spanning multiple panels. The panels typically have approximate lateral dimensions (e.g., length and width) between 30 cm and 90 cm. The thickness of the panels can be between 3 cm and 10 cm. Typically, the support structure in use can define a court area with a length between 120 cm (~4 feet) and 360 cm (~12 feet). These dimensions advantageously provide sufficient length to deliver a challenging putting motion within a compact space. To keep the device as compact as possible, the court area in use is preferably elongated (e.g., with a width between 30 cm and 90 cm). Preferably, the length of the panels (e.g., along the preferred hitting direction) does not significantly exceed their width. This helps to provide a realistic profile on the court surface. For example, conversely, narrow-shaped panels along the length of the panel will create a series of long, flat planes when their respective slopes are adjusted. This particular scenario will not produce a realistic undulating profile on the court surface.

[0021] (For example,) an elongated court surface has a first end and a second end. The direction from the second end to the first end can define a preferred hitting direction. The first and second ends of the court surface correspond to the first and second ends of the supporting structure.

[0022] As described above, the device includes one or more inflatable chambers. Preferably, the one or more inflatable chambers are connected to a support structure. A single inflatable chamber can be used to create challenging profiles for putting practice. However, preferably, the device includes multiple inflatable chambers configured to allow the support structure to tilt in two non-parallel directions. For example, multiple inflatable chambers can tilt "left-right" and "up-down" relative to the direction of the shot. This advantageously increases control over the adjustment of the support structure and allows the user to create complex slope profiles on the course surface.

[0023] In various embodiments, a single adjustable chamber can be used to allow the support structure to tilt along two non-parallel directions. In these embodiments, the lateral position of the single inflatable chamber relative to the device can be adjustable.

[0024] Typically, each inflatable chamber is in communication with a corresponding panel (e.g., connected to a corresponding panel). Therefore, at least one panel is in communication with an inflatable chamber. In a preferred embodiment, each of two or more panels is in communication with at least one slope adjustment element (e.g., connected to at least one slope adjustment element). This allows the slope of each panel to be varied, increasing control over the undulations of the court surface.

[0025] Typically, one or more panels (and in some embodiments, each panel) are in communication with two or more inflatable chambers. By having two (or more) inflatable chambers correspond to the panels, the pitch and tilt of the panels can be adjusted by inflating or deflating each of the two chambers to various degrees in various combinations.

[0026] When in use, providing one or more inflatable chambers for each panel provides stability to the device, as the inflatable chambers are less likely to bounce or shift. The inflatable chambers also make it possible to create complex slope profiles, such as slope profiles that include downward and leftward tilted sections as well as upward and rightward tilted sections.

[0027] However, it is not necessary for the specific panels forming the support structure to have corresponding inflatable chambers. Panels that do not communicate with the inflatable chambers may be referred to herein as “passive” panels. Passive panels can still have their slope adjusted by tilting adjacent panels, particularly in implementations using tension connectors.

[0028] Preferably, the lateral area of ​​each panel is at least twice the size of the lateral area of ​​the corresponding inflatable chamber, and more preferably at least four times the size. In other words, the area defined by the upper surface of the panel is at least twice the size of the area extending through the upper surface of the corresponding (individual) inflatable chamber. When a single panel has multiple inflatable chambers, their total lateral area can be greater than half the size of the lateral area of ​​the corresponding panel.

[0029] Preferably, the inflatable chamber is offset from the center of its corresponding panel to tilt the panel when the inflatable chamber is actuated. However, it is conceivable that in some embodiments, the inflatable chamber may be shaped or otherwise engaged with the corresponding panel so as to cause the panel to tilt even if the inflatable chamber is located at the center of the panel.

[0030] Thus, when the inflatable chamber is inflated, this causes the corresponding panel to tilt, rather than simply rise. Conversely, if the lateral area of ​​the inflatable chamber were similar to the lateral area of ​​the panel, then when inflating and deflating, the inflatable chamber would only raise and lower the panel. Because the lateral area of ​​the inflatable chamber is less than half the lateral area of ​​the panel, when the chamber is inflated, the panel end or panel side rises, resulting in a change in the panel's tilt.

[0031] Preferably, the support structure comprises three or more panels flexibly connected together. Preferably, the panels are arranged in an elongated manner (e.g., end-to-end). Increasing the number of panels advantageously increases the variety of ways the panels can be hinged to produce complex, varying profiles for putting practice. Typically, the support structure comprises no more than 10 panels, preferably no more than 6 panels. A preferred number of panels is 4. This makes each individual panel relatively large compared to the total area of ​​the support structure in use, thus producing a relatively smooth and realistic profile within the contours of the court surface. Preferably, as described above, each panel is connected to its adjacent panel via a tension connector (e.g., a tension hinge).

[0032] A complex slope profile that can be produced includes downward and leftward sloping sections, a flat section, and upward and rightward sloping sections. Another complex slope profile that can be produced includes an upward and rightward sloping section, a flat section, and then a downward and leftward sloping section. Yet another complex slope profile that can be produced includes a leftward sloping section, a rightward sloping section, and then an upward sloping section. As those skilled in the art will understand, other complex slope profiles can be produced by appropriately inflating and deflating the inflatable chamber.

[0033] In various embodiments, each inflatable chamber is configured to have a first inflation position and a second inflation position, in which the inflatable chamber is completely contained within the cavity of the corresponding panel, and in the second inflation position, the inflatable chamber protrudes from the cavity. In other words, when fully deflated, the inflatable chamber is substantially completely contained within the cavity located in the panel, and when partially or fully inflated, the inflatable chamber is configured to protrude from the cavity. Preferably, each cavity corresponds to one inflatable chamber. The inflatable chamber can be removably contained within the cavity and can be secured within the cavity by, for example, interference fit, locking mechanism, or screws.

[0034] In this way, when the inflatable chambers are fully deflated, the panel lies flat because the inflatable chambers are completely contained within their respective cavities. When the inflatable chambers are inflated, they begin to protrude from the cavities and push the panel upwards against the ground or surface where the device is located, causing the panel to tilt. This construction also has the advantage that when not in use, the support structure can be stored more compactly with the deflated inflatable chambers fully contained within their cavities.

[0035] In various embodiments, at least one of the inflatable chambers is disposed substantially at or configured to be positioned at the side edge of the corresponding panel during use. In various embodiments, the inflatable chambers may be disposed at different relative positions on different panels. The side edge of the panel is preferably an edge disposed substantially perpendicular to the direction connecting the panels (e.g., substantially perpendicular to the direction of play). Thus, actuating the inflatable chamber located at the side edge of the corresponding panel causes its corresponding panel to tilt left or right from the angle of play. Typically, the support structure will include a tilt adjustment member having inflatable chambers located at opposite side edges to enable "left" and "right" tilts. In various embodiments, the inflatable chamber of the panel at the first end of the support structure is disposed close to the first end of the support structure. Thus, when viewed along the direction of play, the panel at the first end of the support structure can tilt to a greater extent, for example, relative to its adjacent panel, to create an upwardly tilted profile.

[0036] In various embodiments, an inflatable chamber of a panel at the second end of the support structure is disposed near the second end of the support structure, with the first end opposite the second end. This allows the panel at the second end of the support structure to be tilted, for example, to a greater extent relative to its adjacent panel when viewed along the direction of play, creating a downwardly sloping profile on the court surface of the putting layer.

[0037] By arranging the inflatable chambers in this way, the leverage effect on the connectors of the end panels (e.g., tension hinges, where in use) is increased, meaning that the slope of the end panels is greater relative to the slope of the adjacent panels. Arranging the inflatable chambers in this way also enhances the stability of the platform.

[0038] In various embodiments, the putting device also includes one or more cups configured to receive a golf ball, preferably located at a first end of the support structure. The putting layer placed on the course area includes holes corresponding to the openings of the cups. In some embodiments, the cup may be part of, or may include, an automatic ball recovery system configured to automatically return the golf ball to the user. While the use of a ball recovery system can provide an enhanced user experience, it is not essential, and cups without a ball recovery system can be provided. In some embodiments, the support structure may not include cups, and the resulting putting device can be used on the putting layer by aiming at, positioning, printed, or otherwise marked targets for practice putting.

[0039] In various embodiments, each inflatable chamber is in fluid communication with an actuator configured to inflate the inflatable chamber. Preferably, the actuator includes / or is a pump. The actuator can be manually or automatically operated. In this way, the inflatable chamber can be variablely inflated by a golfer or otherwise to precisely adjust the contours of the court surface. For example, the pump can be configured to be operated by a golfer stepping on it.

[0040] Inflatable chambers are preferably inflated with air (or other suitable gas), but it is conceivable that they can be inflated with a suitable liquid (e.g., water).

[0041] In various embodiments, each inflatable chamber is in fluid communication with an actuable valve that, when actuated, deflates the inflatable chamber. This allows for variable deflation of the inflatable chambers to precisely adjust the contours of the court surface.

[0042] In this article, the combination of the inflatable chamber with the corresponding actuator and valve can be referred to as the "inclination adjustment element".

[0043] Preferably, the actuator and / or actuable valve are located externally to the panel during use. This allows the player to easily inflate and deflate the chamber when using the device. Advantageously, the user, whether standing or sitting, can adjust the profile of the device without needing to use an incline adjustment mechanism on the ground. This ensures easy accessibility to the device.

[0044] Preferably, each panel includes a recess configured to receive and accommodate the actuator and the actuable valve. This allows the device to be stored more compactly when not in use, as the actuator and the actuable valve are housed within the panel.

[0045] Using one or more inflatable chambers to cause changes in the profile of the push rod surface is advantageous for several reasons, besides their ease of use. They are lightweight compared to more complex mechanisms, meaning the device can be more easily folded up and unfolded. They are also generally robust and unlikely to be damaged even if a support structure is stood on. Furthermore, the inflatable chambers dynamically distribute any compressive forces over a large surface area. Therefore, even if a support structure is stood on, not only are the inflatable chambers unlikely to be damaged, but the panel itself is also unlikely to suffer damage.

[0046] In various embodiments, the support structure includes a first configuration and a second configuration, in which the panel is folded and in which the panel is not folded (or “unfolded”) and defines the court area. This allows the device to be compactly stored when not in use.

[0047] In various embodiments, the panel is a semi-rigid panel. In other words, the panel is essentially not easily bent, but not completely inflexible. Thus, when the tilt adjustment is actuated, the individual panel tilts rather than bends significantly. In other words, the panel does not bend significantly under its own weight. Although not typically intended to stand on the device during use, the panel preferably has sufficient flexibility to prevent breakage if accidentally stood on. Preferably, the panel comprises or is formed of one or more open-cell or closed-cell plastic foams. These materials are preferred because they are not easily bent and are lightweight, facilitating the transport and storage of the push rod device when not in use. A preferred material for the panel is expanded polypropylene (EPP). Other suitable materials for the panel may include expanded polystyrene, wood, aluminum, aluminum honeycomb panels, or inflatable PVC.

[0048] In some embodiments, the device may further include a retractable buffer positioned at least partially around the edge of the support structure. The retractable buffer is movable between a retracted position and an extended position. In the retracted position, the retractable buffer is flush with the upper surface of the panel; in the extended position, the retractable buffer protrudes from the upper surface of the panel. In the extended position, the buffer advantageously prevents the golf ball from rolling along the edge of the support structure. When in the retracted position, the buffer advantageously folds the panel for storage.

[0049] The putter layer is typically attached (e.g., configured to be attached to) a course area of ​​a supporting structure. Preferably, the putter layer is removably attached to the supporting structure. The putter layer can be removably attached via fastening devices such as flathead bolts or screws, Velcro®, or carpet clips. Therefore, the putter layer can be replaced with a putter layer that has different rolling characteristics (e.g., to simulate different stimp readings) or a worn putter layer can be replaced. The fastening devices can be configured to allow adjustment of the layer's position once the layer is placed on the course area of ​​the supporting structure. The layer may include eyelets capable of fastening to the removable fastening devices. Preferably, the putter layer is not under tension and is secured to the supporting structure to hold it in place.

[0050] The putter layer and other components of the device (e.g., support structure and inflatable chamber) can be provided as a complete set. The putter layer can typically be provided as a separate component from the rest of the device. Therefore, the invention also provides a complete set including a support structure, one or more inflatable chambers, and a putter layer, which can be assembled to form a golf practice device according to any of the foregoing embodiments. One or more inflatable chambers and the support structure can together form an adjustable support device. Therefore, the complete set can include an adjustable support device and a putter layer (e.g., as separate components) that can be assembled together to form a golf practice device.

[0051] In another aspect of the invention, a golf practice system is provided, comprising: a golf practice apparatus as described above; and a golf course table with an elevated standing surface, wherein a user can stand on the standing surface to perform putting on the golf practice apparatus. Thus, the standing table can be positioned adjacent to the apparatus so that the standing surface substantially matches the height and / or inclination of the golf course surface. The golf course table may have a fixed height (e.g., approximately equal to the average height of the apparatus in a usable tilt position), or it may be adjustable in height and / or inclination. The golf practice apparatus and the golf course table may be provided as a set of components.

[0052] This article also discloses an adjustable support device for a golf practice apparatus, comprising: a support structure including two or more panels flexibly connected together to define a course area configured as a putting pad; and one or more inflatable chambers located on the side of the support structure opposite the course area, wherein the contours of the course area can be altered by inflating and deflating the inflatable chambers. Therefore, the adjustable support device provides advantages equivalent to those of the aforementioned golf practice apparatus. A golf practice apparatus may include such an adjustable support device and a putting pad, such as a putting mat, disposed on the course area.

[0053] In some embodiments, two or more panels include a first panel and a second panel, which are flexibly connected together such that the slope of the first panel is partially dependent on the slope of the second panel. In some embodiments, the panels are flexibly connected together by one or more tension couplings, each of which includes a tension member. In some embodiments, the panels are flexibly connected together via one or more tension hinges, preferably wherein each of the one or more tension hinges includes one or more tension members, the one or more tension members being configured to generate a restoring force pushing the tension hinge to an open position.

[0054] Adjustable support devices and putter layers can be supplied as a set of components. Therefore, the present invention provides a set of components including the aforementioned adjustable support devices and putter layers (e.g., as separate components), wherein the adjustable support devices and putter layers can be assembled into a golf practice apparatus as described herein.

[0055] Adjustable support equipment may include any of the features described above for golf practice equipment. Attached Figure Description

[0070] Figure 5 This is a schematic diagram of a push rod device according to an embodiment of the present invention. Detailed Implementation

[0071] Figure 1A This is a schematic diagram of a portion of the push rod device in an embodiment of the present invention. Specifically, Figure 1A A putter assembly according to an embodiment of the invention is shown, which does not have a putter layer (e.g., putter pad). The support structure 100 includes four connected (e.g., coupled) panels 10a, 10b, 10c, 10d defining a court area 20 in use. Each panel 10a, 10b, 10c, 10d is associated with two slope adjusters 30. Specifically, the first panel 10a is connected to slope adjusters 30a-1 and 30a-2; the second panel 10b is connected to slope adjusters 30b-1 and 30b-2; the third panel 10c is connected to slope adjusters 30c-1 and 30c-2; and the fourth panel 10d is connected to slope adjusters 30d-1 and 30d-2. In this embodiment, the support structure includes four panels; however, in alternative embodiments, fewer or more than four panels may be used. One tilt adjustment element (30a-1, 30b-1, 30c-1, 30d-1) of each panel is disposed near the first side edge 14 of the panel, and another tilt adjustment element (30a-2, 30b-2, 30c-2, 30d-2) is disposed near the second side edge 16 opposite to the first side edge. A recess 18 is provided in each of panels 10a, 10b, 10c, and 10d, and the recess 18 partially accommodates the tilt adjustment element 30. Specifically, the recess 18 accommodates the valve, pipe, and pump of the tilt adjustment element (explained in further detail herein). Figure 1A In the middle, the tilt adjustment parts 30b-2, 30c-2, 30d-2 and 30d-1 are partially accommodated in the grooves of the corresponding panels, and the tilt adjustment parts 30a-1, 30a-2, 30b-1 and 30c-1 are extended laterally to the panels for use.

[0072] In this article, the combination of support structure and slope adjustment component can be referred to as "adjustable support device".

[0073] Although in this embodiment each panel is associated with two tilt adjusters, in some alternative embodiments, some panels may be associated with one or more tilt adjusters. In some embodiments, some panels of the support structure may not be connected to any tilt adjusters and may be referred to as “passive” panels.

[0074] A cup 40 is provided on the first panel 10a at the first end 21 of the support structure. The second end 22 of the support structure is positioned generally opposite the first end 21. The support structure 100 also includes connectors 60 (e.g., "joints") that flexibly connect panels 10a, 10b, 10c, and 10d together to form an elongated court area 20. Here, adjacent panels are connected together by a pair of connectors 60. However, different numbers of connectors or alternative means of flexibly fastening the panels together can be used to connect the panels. However, the panels can be connected together in other configurations to define court areas with different geometries. As will be described herein, in use, a putter layer (e.g., a putter pad) defining the court surface is placed on the court area 20 of the support structure 100 to form a putting device.

[0075] In this embodiment, each panel 10a, 10b, 10c, and 10d measures 60cm (length) × 67cm (width). In this embodiment, the panel thickness is 5.5cm. The panels are joined end-to-end to define a rectangular court area 20 with dimensions of 240cm × 67cm (approximately 8 feet by 2 feet). Therefore, the support structure 100 allows for putters made up to approximately 8 feet in length, providing a suitable length for effective putting practice.

[0076] Panels 10a, 10b, 10c, and 10d are made of semi-rigid materials, such as expanded polypropylene (EPP).

[0077] Each of the four panels 10a, 10b, 10c, and 10d is associated with two inclination adjusters 30 (e.g., connected to or attached to two inclination adjusters 30). The first portion (pump, actuation valve, and tubing) of each inclination adjuster 30 protrudes from the side edge of each panel during use. The second portion (inflatable chamber) of each inclination adjuster 30 is positioned below the panel, thus... Figure 1A Not visible in the view. The undersides of panels 10a, 10b, 10c, and 10d are opposite to the side of court area 20. Each inclination adjuster 30 is configured to tilt its respective panel during inflation, thereby changing the inclination of the panel. During installation, this also changes the inclination of court area 20 and thus the inclination of the court surface of the putter pad.

[0078] As described above, the panels are flexibly connected together using connectors 60. In other words, the panels are not rigidly fastened and have a degree of independent hinge. This advantageously allows for the creation of a realistic “multi-planar” profile across the entire court area by actuating the tilt adjustment members to tilt their respective panels.

[0079] In this embodiment, the connector 60 is a tension hinge that generates tension between adjacent panels. Thus, by actuating the relevant tilt adjustment member to fully tilt a particular panel, adjacent panels will also tilt at least partially. For example, even without actuating tilt adjustment members 30b-1 and 30b-2, actuation of tilt adjustment member 30a-2 may cause directly adjacent panels 10b and 10a to tilt. Depending on the strength of the tension, the tilt of other panels besides directly adjacent panels may also be affected. Therefore, by using the tension hinge 60 to connect the panels, adjustment of a particular tilt adjustment member will result in a change in tilt across multiple panels. This advantageously provides a realistic, progressive profile profile produced with minimal adjustment of the tilt adjustment member across the support structure. The tension hinge will be explained in further detail herein.

[0080] The groove 18 is a channel in the upper surface of panels 10a, 10b, 10c, and 10d. When the support structure is in use, portions of the slope adjustment members 30 extending from panels 10a, 10b, 10c, and 10d can be inserted into the groove 18 when storing the support structure. Therefore, the support structure can be stored more compactly when not in use.

[0081] Each groove 18 includes a removal feature 19 that facilitates easy removal of the receiving portion of the slope adjustment member 30. The golfer can insert their fingers into the removal feature 19 to pry this portion of the adjustment member 30 out of the groove 18. Before use, the golfer can remove this portion of the adjustment member 30 from the groove during the deployment of the support structure. The putter pad covers the groove 18 during installation so that the groove 18 does not interfere with the play settings.

[0082] Figure 1B It is based on Figure 1A A close-up exploded view of the support structure 100 in an embodiment of the present invention. Figure 1B The pump 32 and actuable valve 34 of the inclination adjustment element 30 are shown more clearly. The recess 18 is configured to receive the pump 32, valve 34, and pipes 36 that connect these to the inflatable chambers. The pump 32 and valve 34 of the inclination adjustment element 30 protrude from the sides of each panel during use. The pump 32 and valve 34 are fluidly connected via pipes 36 to inflatable chambers located below each panel 10a, 10b, 10c, 10d (in...). Figure 1B(Not visible in the view). Tube 36 passes through the recesses in panels 10a, 10b, 10c, and 10d to reach the inflatable chamber.

[0083] Pump 32 is actuated by the golfer and is located on the ground near its respective panel during use. Specifically, the golfer can actuate pump 32 by squeezing the pump with their hand or pressing the pump with their foot or club. The golfer actuates valve 34 by squeezing the valve with their hand. When not in use, pump 32 and valve 34 can be stored in recesses 18 in their respective panels.

[0084] In this embodiment, cup 40 is a component of the automatic ball recovery unit and can be a commercially available unit. Figure 1B In the exploded view, the housing 42 of the ball recovery component (e.g., containing a battery and electronic components) is shown as 42. The ball recovery component (consisting of a cup 40 and housing 42) is located within an opening 44 formed in the first panel 10a. In some embodiments, the cup 40 may be an integral part of the ball recovery component 42. The ball recovery component 42 is configured to return the golf ball to a golfer located at a second end 22 of the support member 20, at the end of the support structure 100 opposite to the cup 40. In various embodiments, additional cups may be provided, such that the device includes two or more cups.

[0085] Also shown is a retractable buffer 45 disposed at the edge of the first panel 10a closest to the first end 21 of the course area 20. The buffer 45 is configured to prevent a golf ball traveling from the second end 22 toward the first end 21 from rolling off the edge of the first panel 10a located at the first end 21 and off the course surface of the putting pad. In this embodiment, the buffer 45 extends around the edge of the panel 10a closest to the first end 21 of the course area 20 to define a “C” shape. When in use, the buffer 45 protrudes outward from the upper surface of the panel 10a (see [reference]). Figure 2B When not in use, such as Figure 1B As shown, the buffer can be fully or partially accommodated in a slot located in the first panel 10a for storage.

[0086] Figure 1C This is an alternative view of the supporting structure 100. Specifically, Figure 1C This is a view of the lower side of the support structure 100. Each of the panels 10a, 10b, 10c, and 10d includes two cavities 12, each cavity accommodating multiple inflatable chambers 36 of tilt adjusters 30. More detailed, as... Figure 1C As shown, inflatable chambers 36a-1 and 36a-2 respectively constitute the inclination adjustment components 30a-1 and 30a-2 (as shown). Figure 1A(as shown); inflatable chambers 36b-1 and 36b-2 constitute part of slope adjustment components 30b-1 and 30b-2 respectively; inflatable chambers 36c-1 and 36c-2 constitute part of slope adjustment components 30c-1 and 30c-2 respectively; inflatable chambers 36d-1 and 36d-2 constitute part of slope adjustment components 30d-1 and 30d-2 respectively.

[0087] The cavities 12 and their respective chambers 36 are positioned off-center from the panel to achieve tilting, and close to the first side edge 14 or the second side edge 16 of panels 10a, 10b, 10c, and 10d to achieve left / right tilting relative to the direction of play, in addition to upward / downward tilting. In various embodiments, the inflatable chambers of the panel can be configured in use to be located at the side edge of the corresponding panel. For example, when the support structure is deployed, the chambers can be moved to be positioned at the side of the corresponding panel.

[0088] Each cavity 12 is configured to fully receive the inflatable chamber 36 when it is fully deflated. The depth of the cavity 12 is such that when the inflatable chamber 36 is inflated, the inflatable chamber begins to protrude from the cavity 12, thus tilting the corresponding panel of the cavity 12 when the support structure is placed on a floor or other surface. In other words, the depth of the cavity 12 is generally equivalent to the height of the uninflated inflatable chamber 36.

[0089] Each panel 10a, 10b, 10c, 10d includes two cavities 12: one cavity is located near a first side edge 14 of the panel 10a, 10b, 10c, 10d, and the other cavity is located near a second side edge 16. The inflatable cavities are positioned off-center from the center of the panels, thus enabling not only up / down tilting of the support member from the perspective of elongation, but also left / right tilting. Furthermore, the positioning of the inflatable cavities off-center from the center of the panels 10a, 10b, 10c, 10d enhances the stability of the support structure.

[0090] The cavities 12 of the first panel 10a and the second panel 10b are additionally positioned close to the first end 21 of the support structure at the first end edge, while the cavities 12 of the third panel 10c and the fourth panel 10d are positioned close to the second end 22 of the support structure at the second end edge. Therefore, an uphill profile in the court area 20 can be created by inflating the cavities of the first panel 10a and the second panel 10b, and a downhill profile in the court area 20 can be created by inflating the cavities of the third panel 10c and the fourth panel 10d. The multiple slope adjustment elements arranged across the support structure advantageously enable the creation of multiple complex slope profiles. For example, by equally inflating the cavities (36c-1 and 36c-2) of the third panel 10c and the cavities (36d-1 and 36d-2) of the fourth panel 10d, a flat, then downhill profile can be created in the court area. Therefore, by inflating the chambers (36a-1 and 36a-2) of the first panel 10a and the chambers (36b-1 and 36b-2) of the second panel 10b equally, a flat, then uphill profile can be created in the court area.

[0091] Figure 1D This is a further close-up view of the lower side of the support structure 100. (See attached image.) Figure 1D As shown, the inflatable chambers 36 have a generally similar shape to the openings of the cavity 12. The chambers 36 are secured to their respective cavities using screws and rivets. Alternatively, the chambers can be secured to the cavity 12 by interference fit or by other means, such as a locking mechanism. Figure 1C and Figure 1D A plurality of circular cavities 80 located on the underside of the panel forming the support structure are also shown. These cavities advantageously minimize the weight of the support, thereby improving portability.

[0092] Figure 2A This is a schematic diagram of the push rod device 200 according to an embodiment of the present invention. The push rod device 200 includes the components shown above. Figures 1A to 1D The description includes a support structure 100 and slope adjusters, as well as a putter layer in the form of a putter pad 50 disposed on the course area 20 of the support structure 100. The putter pad 50 extends from a first end 21 to a second end 22 across the course area to define a course surface 51 that conforms to the adjustable profile of the underlying support structure 100. The putter pad smooths any edges between adjacent panels of the underlying support structure and provides a smooth course surface. A preferred shot direction PD is defined from the second end 22 to the first end 21. Thus, the user of the putting device 200 can use multiple slope adjusters to adjust the slope of the course surface 51 to produce a challenging yet realistic profile along the shot direction PD. Specifically, the slope adjusters can be actuated to produce multiple slopes along the shot direction, mimicking a real green. However, a single constant slope can be achieved through appropriate actuation of the slope adjusters if desired.

[0093] For example, inflating the inflatable chambers of the slope adjusters 30a-1, 30b-1, 30c-1, and 30d-1 can cause the corresponding panel to tilt downwards to the left from the angle of the shot, producing a "right-to-left" turn putt. Conversely, inflating the inflatable chambers of the slope adjusters 30a-2, 30b-2, 30c-2, and 30d-2 can cause the corresponding panel to tilt downwards to the right from the angle of the shot, producing a "left-to-right" turn putt. Uphill and downhill slope putts can also be established based on the relative actuation of the slope adjusters at the first and second ends of the support structure. Typically, multiple slope adjusters allow the court surface 51 to tilt in two non-parallel directions (e.g., tilted perpendicular to the shot and tilted parallel to the shot). The panels, connected via tension hinges, produce smooth, realistic contour changes across the entire court surface 51. As described, because the panels are flexibly connected to the tension hinges, operating a single tilt adjustment element 30 can cause tilting of its corresponding panel and the panels adjacent to it. This advantageously creates a tilt profile in the court surface that is not limited to the tilt adjustment element being operated.

[0094] Figures 3A to 3D The first, second, third, and fourth configurations of the push rod device are described respectively.

[0095] exist Figure 3A The first configuration described herein is that of an uphill putter. In this first configuration, the inflatable chambers 36a-2 and 36a-1 of panel 10a are inflated to a greater extent than the inflatable chambers 36b-1 and 36b-2 of panel 10b to create an uphill profile on the course surface. Panel 10c is also tilted due to the inflation of the inflatable chambers 36a-2, 36a-1, 36b-1, and 36b-2.

[0096] exist Figure 3B The second configuration described herein is that of a downhill putter. In this second configuration, the inflatable chambers 36d-2 and 36d-1 of panel 10d are inflated to a greater extent than the inflatable chambers 36c-1 and 36c-2 of panel 10c, to create a downhill profile on the course surface. Due to the inflation of the inflatable chambers 36d-2 and 36d-1 and 36c-1 and 36c-2, panel 10b is also tilted.

[0097] exist Figure 3CThe third construction described is that of a "humpback" putter. In this third construction, the inflatable chambers 36b-2 and 36b-1 of panel 10b and the inflatable chambers 36c-2 and 36c-1 of panel 10c form a raised profile on the course surface. These chambers are inflated to a greater extent than the chambers 36a-2 and 36a-1 of panel 10a and the chambers 36d-2 and 36d-1 of panel 10d. Therefore, due to the inflation of the inflatable chambers 36b-2 and 36b-1 and 36c-2 and 36c-1, as well as the tension hinge, panels 10a and 10b are also tilted, but to a lesser degree than panels 10b and 10c.

[0098] exist Figure 3D The fourth structure depicted is an uphill, left-to-right push rod structure. For example, this fourth structure can be achieved by inflating the inflatable chambers 30a-2 and 30b-2 to directly and appropriately adjust the inclination of panels 10a and 10b. To create... Figure 3D The specific outline shown indicates that the inflatable chamber 30a-2 is more inflated than the inflatable chamber 30b-2.

[0099] It should be noted that in the above example, the tension hinge connecting panels 10a and 10b opens in the first direction, while the tension hinge connecting panels 10b and 10c opens in the opposite direction. The hinges connecting panels 10c and 10d are installed with the same construction as the hinge connecting panels 10a and 10b. Therefore, in Figure 3A and Figure 3B In this scenario, the surface between panels 10b and 10c remains largely flat (because the hinge generally doesn't open more than 180 degrees), but in Figure 3C The scene shown achieves a "hunchback" silhouette. Figure 3C In this configuration, although panels 10a and 10b are substantially coplanar due to the construction of the tension hinges connecting them, the hinges can open slightly more than 180 degrees to provide a more gradual change in the illustrated profile. This can also be seen in the connection between panels 10c and 10d. In a preferred embodiment, as described above, the closing direction of the hinge group can alternate for each respective panel pair. This hinge construction facilitates folding (described later), but it is conceivable that different hinge constructions could be used to achieve different slope profiles.

[0100] Refer to the return Figure 2AA hole 52 is also provided through the putter pad 50. The diameter of the hole 52 is equal to the edge of the cup 40. The hole 52 is located at a lateral alignment with the cup 40, allowing a golf ball rolling along the putter pad to fall into the cup 40 through the hole 52. However, it is conceivable that in some embodiments, the support structure may not include the cup (and correspondingly, the pad may not include the hole 52). In these embodiments, putting can be practiced by aiming at a target (e.g., a physical target or marker) located on the pad.

[0101] The push rod pad 50 is preferably removably attached to the support structure 100, for example via a fastening device such as a flathead bolt or screw, Velcro®, or carpet clip. The push rod pad can be manufactured using techniques known in the art.

[0102] As will be noted, the course surface 51 of the putting device 200 is higher than the floor due to the thickness of the panel forming the support structure. For putting practice purposes, this slight height difference between the golfer standing on the ground and the course surface 51 is acceptable. However, a table 99 can be provided with the putting device 200. The user can stand on the table 99 to minimize any difference in height between the golfer's feet and the putting device. The table 99 can have a fixed height equal to the average height of the course surface (as shown), or it can have an adjustable height and / or slope, which can be configured to substantially match the height and / or slope of a course surface constructed with a given slope. When the user stands on the table 99, a preferred hitting position is created. The combination of the table and the putting device 200 forms a putting system.

[0103] Figure 2B It is based on Figure 2A A close-up view of the push rod device 200 according to an embodiment of the present invention. Figure 2A The view is equivalent to Figure 1B The view shown, however, creates a smooth court surface due to the installation of the putter pad 50, which covers the connector 60, the groove 18, the interface between the panels, and the ball return housing 42. Additionally, although... Figure 1B The buffer 45 is shown in its retracted position, but Figure 2B A buffer 45 is shown in its protruding position, wherein the buffer 45 is configured to prevent the golf ball 90 from rolling off the putter assembly 200 if it misses the cup 40.

[0104] Figure 2C It is based on Figure 2A A partially exploded view of the push rod device 200 according to an embodiment of the present invention. The fourth panel 10d of the support member 100 includes a chamfered end 70 and a removable pad cover 55 that at least partially covers the chamfered end 70. Except according to Figure 2A In addition to the features described in the implementation method, Figure 2C The pad cover 55, removed from the fourth panel 10d, is described. As mentioned above, the putter pad 50 is removably attached to the support structure 100, allowing the use of different pads. Typically, the panels have dimensions that allow the course area 20 to have a length (along the direction of play) longer than the putter pad 50, and different pads can have different lengths within manufacturing tolerances. When the putter pad is installed, it can be positioned correctly with its second end under the pad cover 55 to ensure that when the putter assembly 200 is used, the hole 52 in the putter pad 50 remains aligned with the opening of the cup 40, as the pad can be clamped in the correct position under the pad cover 55. The chamfered end 70 allows the pad cover 55 to be installed at the same height as the course surface 51, preventing fouls during the golfer's swing. However, in alternative embodiments, the putter assembly may not include the chamfered end 70 and the pad cover 55 (e.g., as...). Figure 3D (As shown). In this alternative embodiment, the fastener for attaching the push rod pad to the support structure can be adjustable (e.g., an adjustable mechanical clamp) to accommodate push rod pads of different lengths (e.g., within manufacturing tolerances).

[0105] Figure 4A This is an exploded view of a connector 60 in the form of a tension hinge according to an embodiment of the present invention. The tension hinge 60 can be used in conjunction with any of the embodiments described herein. A preferred hitting direction PD is shown for reference. The tension hinge includes an upper plate 62 and a lower plate 64. The upper plate 62 and the lower plate 64 are connected by a plurality of support posts 68 disposed between the upper plate and the lower plate to fix the two plates. In addition, a tension member 69 is provided between the upper plate 62 and the lower plate 64.

[0106] The upper plate 62 has two (e.g., equal-sized) portions 62a and 62b. Similarly, the lower plate 64 has two portions 64a and 64b. The upper and lower plates can be formed of a suitable material such as plastic. The portions 62a of the upper plate and 64a of the lower plate form the first segment of the connector 60, and the portions 62b of the upper plate and 64b of the lower plate form the second segment of the connector 60. A tension member 69 connects these two segments of the tension hinge, allowing a degree of free hinge between the first and second segments of the connector. Therefore, the connector 60 functions as a tension hinge, wherein the tension generated by the tension member 69 causes the hinge to push to... Figure 4AThe restoring force in the "open" position is shown, where the two segments of the hinge are generally planar. First segments 62a, 64a can be disposed on the first panel, and second segments 62b, 64b can be disposed on the second panel to allow the panels to be flexibly connected to the tension hinge. The upper plate 62 includes a hinge (shown as 160) (e.g., polypropylene) that facilitates the pivoting of the connector 60. Here, the upper plate 62 includes a "movable" hinge that is part of the single upper plate. However, other types of hinge components can be used to achieve the pivoting of the tension hinge. When the hinge 60 is in the position as... Figure 4A When the panel is in the open position shown, the connected panels will be in the same plane.

[0107] In this embodiment, tension member 69 includes a portion of an elastic rope (e.g., a "bungee rope"). In alternative embodiments, tension member may include a spring or other material suitable for forming an extendable tension member. The tension of tension member 69 is selected such that when the first panel is tilted by inflation of its corresponding inflatable chamber, the directly connected panel (which is not directly tilted by the inflatable chamber) is partially tilted. In a preferred embodiment, adjacent panels are tilted to a smaller angle than the first panel, but the adjacent panels do not remain untilted when the first panel is tilted.

[0108] This preferred embodiment is in Figure 4B As shown in scenario 2, it can be seen that the end of panel 2, adjacent to panel 1, is partially raised relative to the horizontal plane. However, the slope of panel 2 does not match that of panel 1, which has been tilted by the inflation of its corresponding inflatable chamber 36. In scenario 2, the restoring force of the tension hinge 60 overcomes the weight of panel 2, thus panel 2 is partially raised.

[0109] In scenario 1, the two panels are connected by a conventional tension-free hinge. Therefore, when panel 1 is tilted, panel 2 remains tilted and is unaffected by the tilt of panel 1.

[0110] While Scenario 1 provides a multi-planar break due to the flexible connection between the two panels, it is a less desirable arrangement compared to Scenario 2 because the gradient of the course surface changes more abruptly when the panels are tilted. This is less similar to the contours of the green compared to the gradually increasing gradient between adjacent panels described in Scenario 2.

[0111] The tension of the elastic component should be selected such that the user can fold the panel from approximately 180° to the folded position, such as... Figure 5As shown. In various embodiments, the tension hinge 60 can close in one direction but not in the other. In other words, the hinge can open without an angle significantly greater than 180 degrees. The tension hinge can open with a small range of angles greater than 180 degrees (e.g., up to about 10 degrees), for example, to prevent accidental breakage. The tension hinge 60 can be configured in opposite ways between different pairs of panels to facilitate folding of adjacent panels in different directions. For example, the connector for the end panels only allows the end panels to fold inward, while the connector for the middle panels only allows the middle panels to fold outward. For example, the connector or connector 60 can be configured with... Figure 4B The closing direction is opposite to that described in scenarios 1 and 2. In other words, the closing direction of the connector or connector group can alternate for their respective panel pairs. This allows for easy folding of the push rod device and also enables different configurations of the external profile.

[0112] Figure 5 This is a schematic diagram of the support structure 100 for the push rod device in a folding configuration. In this configuration, the support structure 100 can be advantageously and compactly stored (e.g., after removing the push rod pad first). For example, the features of the tilt adjustment member are completely stored in the cavities and recesses of their corresponding panels (as described above), and thus panels 10a, 10b, 10c, and 10d can be folded to be flush with each other. As mentioned above, the connector 60 operates as a hinge, hinged 180 degrees. Therefore, panels 10a, 10b, 10c, and 10d do not need to be disassembled from each other when storing the support structure.

[0113] The above embodiments describe a putter device comprising four connected panels, each panel communicating with two slope adjusters. However, it should be understood that other configurations can be used. For example, the support structure may include fewer or more than four panels. Furthermore, while the configuration where each panel communicates with two slope adjusters advantageously enhances control over the slope of the court surface and improves the stability of the device, it is conceivable that in some embodiments, only a portion of the panels may include slope adjusters. In some scenarios, it is envisioned that the support structure may include only a single slope adjuster.
