Description

Technical Field

[0001] The utility model relates to a putting device and a system, and in particular to improvements or related improvements of a golf practice device and a system to help golfers improve their putting skills. Background Art

[0002] Various known putting aids, such as putting mats, enable golfers to practice putting away from the golf course. Some putting aids include features that further help golfers improve their putting technique. For example, known putting aids may include slope in the playing surface to add an element of difficulty when putting.

[0003] Additionally, some putting assist devices known in the art include adjustable surfaces. Golfers may be able to adjust properties of the playing surface of these devices, such as slope, to introduce an element of variable difficulty or to practice a specific putt.

[0004] Some putting assist devices known in the art provide variable pitch by implementing a complex network of mechanical actuators that precisely adjust to the contours of the playing surface. However, these approaches are difficult and expensive to manufacture due to their complexity. They are also difficult to operate and often require computer control, further increasing cost and complexity.

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

[0006] Therefore, there is a need for improvements in or relating to adjustable putting assist devices. Utility Model Content

[0007] In one aspect of the present invention, a golf practice device is provided, comprising: a support structure comprising two or more panels that are flexibly connected together (e.g., in use) to define a playing surface; a putter layer that is disposed (e.g., in use) on the playing surface area of ​​the support structure, wherein the putter layer defines a playing surface; and one or more inflatable chambers located on a side of the support structure opposite the playing surface, whereby the contour of the playing surface can be changed by inflation and deflation of the inflatable chambers.

[0008] The inflatable chambers are located on the side of the support structure opposite the putting surface. Thus, when the inflatable chambers are adjusted, because the changes in the profile (e.g. slope or contour) of the putting surface extend over the lateral area of the panel, these changes are relatively gradual, as opposed to the locally steep mounds or "mole hills" that would result if the inflatable chambers were positioned between the panels and the putting layer. The profile of the putting surface can be described relative to the ground or other surface on which the apparatus is positioned. In this way, the putting apparatus advantageously enables the slope and undulations to be adjusted in a realistic manner similar to the profile of a green on a golf course. The putting layer also smooths any edges or steps between adjacent panels, resulting in a realistic putting surface.

[0009] The putting layer disposed (e.g. positioned) on the putting area defines the putting surface of the putting apparatus. In other words, in use, a golf ball is struck so as to roll on the putting surface. The putting layer is typically disposed so as to substantially completely cover the putting area. The putting layer can comprise a single layer of material or multiple (e.g. multiple sub-layers) of material. The putting layer can comprise nylon, carpet, artificial turf or other suitable material for providing a realistic putting surface. Preferably, the putting layer comprises a layer of nylon over a layer of thermoplastic rubber. The putting layer is generally flexible so as to conform to the profile of the support. In this way, as described above, the profile of the putting surface can be adjusted by operation of the one or more slope adjustment members to create realistic undulations. The putting layer is typically in the form of a putting mat. The putting layer can be configured in use to be disposed on the putting area of the support structure.

[0010] The panels of the support are flexibly connected (e.g. flexibly coupled) together so as to define the putting area. The putting layer is typically positioned so as to substantially completely cover the putting area. The putting area defined by the panels is the area of the support structure defined by the tops of the panels in use. In other words, the putting area has a larger lateral area than the lateral area defined by a single panel. The panels can typically be connected together end-to-end (e.g. laterally) in the longitudinal direction so as to define an elongate putting area. The inflatable chambers are disposed beneath the panels opposite the putting surface in use. In other words, the support structure has a first side defining the putting area and an opposite second side on which the inflatable chambers are located. Thus, when the inflatable chambers are inflated, the corresponding panels will tilt such that their slope is changed. This thus changes the slope of the putting area and therefore the putting surface, as the changes in slope "spread" over the lateral area of the panel. Because the panels are flexibly connected (e.g. flexibly coupled), the panels adjacent to the actively tilting panel can tilt to a different extent to the actively tilting panel, enabling a realistic multi-planar undulation across the putting surface to be created.

[0011] Unlike known putting aids that implement a complex network of actuators that precisely adjust the contour of the playing surface at many individual locations by adjusting the slope of multiple panels, the present invention uses a relatively limited number of adjustment points to achieve realistic undulations across the playing surface and avoids the problem of creating unrealistic "molehill" slopes.

[0012] Two or more panels are flexibly connected together. In other words, the panels are not rigidly connected. In this way, the panels can be hinged at least partially independently of each other. The panels can be flexibly connected or coupled together via one or more hinges or other connectors suitable for creating a 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 playing surface with a variable contour. For example, the playing surface can be adjusted to include an "uphill" portion and a "flat" portion. In contrast, if there is only one panel in the support structure, or if the panels are rigidly connected, the playing surface will only include a contour with a constant slope, which is not a typical feature of a putting green. However, it should be noted that, if desired, the inflatable chamber of the present invention can be controlled to provide a constant slope of the supporting structure.

[0013] In a preferred embodiment, the two or more panels include a first panel and a second panel, and the first panel and the second panel are flexibly connected together so that the slope of the first panel is partially dependent on the slope of the second panel. In this way, when the first panel is tilted by actuation of the inflatable chamber, the panel connected to the tilted panel may also partially tilt, thereby advantageously minimizing local ridges or steps between adjacent panels. In this way, the slope of the second panel is partially dependent on the slope of the connected first panel.

[0014] Preferably, the panels are flexibly connected together by one or more tension connectors, each of the one or more tension connectors comprising a tension member. In this way, the tension members generate a restoring force that resists the fully independent hinging of the panels, so that the slope of the panels connected using the tension connector is partially dependent on each other. The restoring force generally pushes the connected panels towards a position where they define a flat surface. The use of tension connectors to provide partial dependence of the slope of the connected panels advantageously means that relatively few inflatable chambers can be used to produce realistic changes in the contour of the playing surface. Advantageously, when adjusting the contour of the playing surface, the tension is in the support structure (e.g. the tension members of the tension connector are under tension). This means that there is no need to adjust the tension in the putting layer (e.g. the putting pad) because the putting layer is fully supported by the support structure.

[0015] The strength of the tension members (eg, the strength of the restoring force) can be selected based on the number of panels present and the degree of slope dependence of the panels to be connected. Typically, the tension members are configured to generate a restoring force greater than the weight of the panels.

[0016] A preferred example of a tension connector is a tension hinge. Thus, 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 that urges the tension hinge toward an open position. In such an embodiment, the panels may be described as being hingedly connected.

[0017] The tension hinge is in an open position when the two connected panels define a substantially flat surface. Typically, the opening angle of the hinge is substantially no greater than 180 degrees. When a first panel tilts, the tension hinge connecting the first panel to a (directly) adjacent second panel begins to close. The restoring force overcomes the weight of the second panel, thereby causing the second panel to tilt. The tension provided by the one or more tension members is selected so that the second panel tilts less than the first panel, but does not cause the adjacent panel to remain fixed when the first panel tilts. Preferably, the tension member of the tension hinge (or other tension connector) includes an elastic cord ("bungee") or spring that provides the required tension. The hinge is partially closed by inflating an inflatable chamber in one of the panels. The greater the amount of inflation in the chamber of the first panel, the greater the amount the hinge closes.

[0018] In embodiments comprising more than two panels, the orientation of the tension hinges connecting different pairs of panels can vary. For example, one hinge (or set of hinges) connecting a first pair of panels can close in one direction, while another hinge (or set of hinges) connecting a second pair of hinges can close in the opposite direction. This arrangement can be advantageously used to control the degree and manner of articulation of the playing surface. In various embodiments, the direction in which the hinges or hinge groups close can alternate for corresponding pairs of panels. Additionally, this can make it easier to fold the panels for compact storage of the device. For example, the hinge groups connecting the end panels can close in one direction, while the hinge groups connecting the panels in the middle of the support structure can close in the opposite direction, to achieve an "accordion-style" fold.

[0019] Tension hinges may allow the panels to be folded to store the unit without removing the push rod assembly.

[0020] While not required, the panels are preferably generally rectangular in shape (and may be generally square). This geometry enables the creation of a generally continuous playing surface across multiple panels. Panels typically have approximate lateral dimensions (e.g., length and width) between 30 cm and 90 cm. The thickness of the panels may be between 3 cm and 10 cm. Typically, the support structure, when in use, can define a playing surface having a length between 120 cm (~4 feet) and 360 cm (~12 feet). These dimensions advantageously provide a sufficiently long length to provide challenging putting within a compact space. To keep the device as compact as possible, the playing surface is preferably elongated (e.g., having a width between 30 cm and 90 cm) when in use. Preferably, the length of the panels (e.g., along the preferred direction of play) does not significantly exceed their width. This helps provide a realistic contour on the playing surface. For example, panels that are narrow along their length would, in contrast, create a series of long, flat planes when their respective pitches are adjusted. This particular scenario would not result in a realistic, undulating contour on the playing surface.

[0021] The (e.g., elongated) playing surface has a first end and a second end. A direction from the second end to the first end may define a preferred direction of play. The first and second ends of the playing surface correspond to the first and second ends of the support 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 contours for practicing putting. However, preferably, the device includes multiple inflatable chambers configured to allow the support structure to tilt in two non-parallel directions. For example, the multiple inflatable chambers can be tilted both left and right and up and down relative to the direction of play. This advantageously increases control over the adjustment of the support structure and enables the user to create complex slope contours on the playing surface.

[0023] In various embodiments, a single adjustable chamber can be used to enable the support structure to tilt in 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 (e.g., connected to) a corresponding panel. Thus, at least one panel is in communication with an inflatable chamber. In a preferred embodiment, each of the two or more panels is in communication with (e.g., connected to) at least one tilt adjustment member. In this way, the tilt of each panel can be varied to increase control over the undulations on the playing surface.

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

[0026] Providing one or more inflatable chambers for each panel, when used, provides stability to the device, as the inflatable chambers are less likely to bounce or shift. The inflatable chambers also enable the creation of complex camber profiles, for example, a camber profile that includes portions that lean downward and to the left as well as portions that lean upward and to the right.

[0027] However, it is not necessary for the particular panel that forms the support structure to have a corresponding inflatable chamber. Panels that are not in communication with an inflatable chamber can be referred to herein as“passive” panels. Passive panels can still have their camber adjusted by the tilting of adjacent panels, particularly in embodiments that use tension links.

[0028] Preferably, the lateral area of each panel is at least twice as large, and preferably at least four times as large, as the lateral area of the corresponding inflatable chamber. In other words, the area defined by the upper surface of the panel is at least twice as large as the area that extends 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 chambers are offset from the center of their corresponding panels to cause the panels to tilt when the inflatable chambers are actuated. However, it is contemplated that in some embodiments, the inflatable chambers can be shaped or otherwise interfaced with the corresponding panels so as to cause tilting of the panels even if the inflatable chambers are located at the center of the panels.

[0030] As such, when the inflatable chambers are inflated, this causes their corresponding panels to tilt, rather than simply rise upward. In contrast, if the lateral area of the inflatable chambers were similar to the lateral area of the panels, then the inflatable chambers would simply raise and lower the panels when inflated and deflated. Because the lateral area of the inflatable chambers is less than half the lateral area of the panels, when the chambers are inflated, the panel end or panel side rises, causing a change in the camber of the panel.

[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 in which the panels can be hinged to create complex, varying profiles for putting practice. Typically, the support structure comprises no more than 10 panels, preferably no more than 6 panels. The preferred number of panels is 4. In this way, each individual panel is relatively large compared to the total area of ​​the support structure in use, thereby creating a relatively smooth and realistic profile in the profile 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] One complex slope profile that can be generated includes a portion that slopes downward and to the left, a flat portion, and a portion that slopes upward and to the right. Another complex slope profile that can be generated includes a portion that slopes upward and to the right, a flat portion, and then a portion that slopes downward and to the left. Another complex slope profile that can be generated includes a portion that slopes left, a portion that slopes right, and then a portion that slopes upward. As will be understood by those skilled in the art, other complex slope profiles can be generated by appropriate inflation and deflation of the inflatable chamber.

[0033] In various embodiments, each inflatable chamber is configured to have a first inflated position in which the inflatable chamber is completely within the cavity of the corresponding panel and a second inflated position in which 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, there is one inflatable chamber for each cavity. The inflatable chamber can be removably contained within the cavity and can be retained within the cavity by, for example, an interference fit, a locking mechanism, or screws.

[0034] Thus, when the inflatable chambers are fully deflated, the panels lie flat because the inflatable chambers are fully contained within their respective cavities. As the inflatable chambers are inflated, they begin to protrude from the cavities and push the panels upward against the ground or surface on which the device is located, causing the panels to tilt. This configuration 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 generally disposed at the side edge of the corresponding panel during use or is configured to be positioned at the side edge of the corresponding panel. In various embodiments, the inflatable chambers can be disposed at different relative positions on different panels. The side edges of the panels are preferably edges disposed generally perpendicular to the direction connecting the panels (e.g., generally perpendicular to the direction of play). In this way, actuating the inflatable chambers located at the side edges of the corresponding panels causes their corresponding panels to tilt left or right from the angle of the direction of play. Typically, the support structure will include an inclination adjustment member having inflatable chambers located at opposite side edges so as to be able to produce a "left" tilt and a "right" tilt. In various embodiments, the inflatable chambers of the panels at the first end of the support structure are disposed near the first end of the support structure. In this way, when viewed along the direction of play, the panels at the first end of the support structure can, for example, be tilted to a greater extent relative to their adjacent panels to produce an upwardly tilted profile.

[0036] In various embodiments, the inflatable chambers of the panels at the second end of the support structure are positioned proximate the second end of the support structure, with the first end being opposite the second end. Thus, for example, the panels at the second end of the support structure can be tilted more than their adjacent panels when viewed in the direction of play to create a downwardly sloping profile in the playing surface of the putter layer.

[0037] By arranging the inflatable chambers in this way, the leverage effect on the end panel's couplings (e.g. tension hinges, where used) is increased, meaning that the slope of the end panel 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 further comprises one or more cups configured to receive a golf ball, preferably wherein the one or more cups are disposed at a first end of the support structure. A putter layer placed over the court area includes a hole corresponding to the opening of the cup. In some embodiments, the cup may be an integral part of an automatic ball recovery member configured to automatically return a golf ball to a user, or may include an automatic ball recovery member configured to automatically return a golf ball to a user. While the use of a ball recovery member may provide an enhanced experience for the user, this is not required, and a cup without a ball recovery member may be provided. In some embodiments, the support structure may not be provided with a cup, and the resulting putter device may be used by practicing putting by aiming at a target positioned, printed, or otherwise marked on the putter layer.

[0039] In various embodiments, each inflatable chamber is in fluid communication with an actuator configured to inflate the inflatable chamber. Preferably, the actuator comprises (or is) a pump. The actuator can be manually operated or automated. In this manner, the inflatable chamber can be variably inflated by the golfer or otherwise to precisely adjust the contours of the court surface. For example, the pump can be configured to be operated by the golfer stepping on the pump with their foot.

[0040] The inflatable chambers are preferably inflated with air (or other suitable gas), but it is envisaged that they could be inflated with a suitable liquid (such as water).

[0041] In various embodiments, each inflatable chamber is in fluid communication with an actuatable valve that, when actuated, deflates the inflatable chamber. In this way, the inflatable chambers can be variably deflated to precisely adjust the contours of the playing surface.

[0042] The combination of an inflatable chamber and corresponding actuator and valve may be referred to herein as a "rake adjuster."

[0043] Preferably, the actuator and / or actuatable valve are located externally of the panel during use. This allows the golfer to easily inflate and deflate the chamber while using the device. Advantageously, the user can adjust the profile of the device while standing or sitting, without requiring the user to use the incline adjustment member on the ground. This ensures that the device is easily accessible.

[0044] Preferably, each panel comprises a recess configured to receive and accommodate the actuator and the actuatable valve. In this way, when not in use when storing, the device can be stored more compactly because the actuator and the actuatable valve are arranged in the panel.

[0045] Using one or more inflatable chambers to induce changes in the profile of the putter's surface is advantageous for several reasons, beyond its ease of use. Compared to more complex mechanisms, they are lightweight, meaning the device can be more easily stowed and deployed. They are also generally sturdy and less likely to be damaged if a support structure is positioned above. Furthermore, the inflatable chambers dynamically distribute any compressive forces over a large surface area. Therefore, if a support structure is positioned above, not only are the inflatable chambers less likely to be damaged, but the panel itself is also less likely to suffer damage.

[0046] In various embodiments, the support structure includes a first configuration in which the panels are folded and a second configuration in which the panels are unfolded (or "unfolded") and define a court area. In this way, the device can be compactly stored when not in use.

[0047] In various embodiments, the panel is a semi-rigid panel. In other words, the panel is substantially inflexible, but not completely inflexible. In this way, when the tilt adjustment member is actuated, the individual panels tilt, rather than bend significantly. In other words, the panels do not bend significantly under their own weight. Although it is not generally intended to stand on the device during use, the panels are preferably flexible enough not to break when accidentally stood on. Preferably, the panels include or are formed of one or more open-cell or closed-cell plastic foams. These materials are preferred because they are inflexible and lightweight, making it easy for the push rod device to be transported and stored when not in use. The 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 bumper positioned at least partially around the edge of the support structure. The retractable bumper is movable between a retracted position, in which the bumper is flush with the upper surface of the panel, and a deployed position, in which the bumper protrudes from the upper surface of the panel. In the deployed position, the bumper advantageously prevents golf balls from rolling around the edge of the support structure. When in the retracted position, the bumper advantageously allows the panel to fold for storage.

[0049] The putter layer is typically attached to (e.g., configured to be attached to) the court area of ​​the support structure. Preferably, the putter layer is removably attached to the support structure. The putter layer may be removably attached to the support structure via fastening means (e.g., flat head bolts or screws, The layer may be removably attached to a support structure (e.g., a carpet clip). Thus, the putter layer may be replaced with a putter layer having different rolling characteristics (e.g., to simulate a different stimp reading), or to replace a worn putter layer. The fastening means may be configured to allow adjustment of the position of the layer once it is placed on the court area of ​​the support structure. The layer may include eyelets that can be fastened to the removable fastening means. Preferably, the putter layer is not under tension and is secured to the support 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 set of parts. The putter layer can generally be provided as a component separate from the rest of the device. Therefore, the present invention also provides a set of parts, including a support structure, one or more inflatable chambers and a putter layer, which can be assembled to form any of the golf practice devices described above. The one or more inflatable chambers and the support structure can together form an adjustable support device. Therefore, the set of parts 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 present invention, a golf practice system is provided, comprising: a golf practice device as described above; and a golf course table having an elevated standing surface, wherein a user can stand on the standing surface to putt on the golf practice device. The standing surface can be positioned adjacent to the device so that the standing surface substantially matches the height and / or slope of the golf course surface. The golf course table can have a fixed height (e.g., approximately equal to the average height of the device in its available tilt positions) or can be adjustable in height and / or slope. The golf practice device and golf course table can be provided as a kit.

[0052] Also disclosed herein is an adjustable support device for a golf practice device, comprising: a support structure comprising two or more panels flexibly connected together to define a playing surface configured to receive a putting surface; and one or more inflatable chambers located on a side of the support structure opposite the playing surface, wherein the contour of the playing surface can be altered by inflating and deflating the inflatable chambers. Thus, the adjustable support device offers the same advantages as the golf practice device described above. The golf practice device may include such an adjustable support device and a putting surface, such as a putting mat, disposed on the playing surface.

[0053] In some embodiments, the two or more panels include a first panel and a second panel, the first panel and the second panel being flexibly connected together such that the slope of the first panel depends in part on the slope of the second panel. In some embodiments, the panels are flexibly connected together by one or more tension couplings, each of the one or more tension couplings comprising 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 comprises one or more tension members, the one or more tension members being configured to generate a restoring force that urges the tension hinge toward an open position.

[0054] The adjustable support device and the putter layer may be provided as a kit. Thus, the present invention provides a kit comprising the adjustable support device and the putter layer (e.g., as separate components), wherein the adjustable support device and the putter layer may be assembled into a golf practice device as described herein.

[0055] The adjustable support device may include any of the features described above with respect to the golf practice apparatus. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Figure 1A Schematic diagram of a part of the push rod device in the embodiment of the present invention. In particular, Figure 1A A putting device according to an embodiment of the present invention is shown without a putting layer (e.g., a putting mat) installed. The support structure 100 includes four connected (e.g., coupled) panels 10a, 10b, 10c, 10d that define a court area 20 in use. Each panel 10a, 10b, 10c, 10d is associated with two reclining members 30. Specifically, the first panel 10a is connected to the reclining members 30a-1 and 30a-2; the second panel 10b is connected to the reclining members 30b-1 and 30b-2; the third panel 10c is connected to the reclining members 30c-1 and 30c-2; and the fourth panel 10d is connected to the reclining members 30d-1 and 30d-2. In this embodiment, the support structure includes four panels, but in alternative embodiments, less than four or more than four panels may be used. One recliner (30a-1, 30b-1, 30c-1, 30d-1) of each panel is positioned proximate a first side edge 14 of the panel, and another recliner (30a-2, 30b-2, 30c-2, 30d-2) is positioned proximate a second side edge 16 opposite the first side edge. A recess 18 is provided in each of the panels 10a, 10b, 10c, and 10d that partially accommodates the recliner 30. Specifically, the recess 18 accommodates the recliner valves, tubes, and pumps (explained in further detail herein). Figure 1A In the embodiment, the recliner members 30b-2, 30c-2, 30d-2 and 30d-1 are partially accommodated in the grooves of the corresponding panels, and the recliner members 30a-1, 30a-2, 30b-1 and 30c-1 are unfolded transversely to the panels for use.

[0072] The combination of the support structure and the recline adjustment may be referred to herein as an "adjustable support apparatus."

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

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

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

[0076] The panels 10a, 10b, 10c, 10d are made of a semi-rigid material, such as expanded polypropylene (EPP).

[0077] Each of the four panels 10a, 10b, 10c, 10d is associated with two recliners 30 (e.g., connected to or coupled to two recliners 30). The first portion of each recliner 30 (pump, actuator valve, and tubing) protrudes from a side edge of each panel during use. The second portion of each recliner 30 (the inflatable chamber) is positioned below the panel so that the recliner is positioned below the panel. Figure 1AThe underside of panels 10a, 10b, 10c, and 10d is the side opposite playing area 20. Each tilt adjuster 30 is configured to tilt its respective panel when inflated, thereby changing the tilt of the panel. When installed, this also changes the tilt of playing area 20 and, therefore, the tilt of the playing surface of the putting mat.

[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 articulation. This advantageously allows for the creation of a realistic "multi-plane" profile over the entire playing surface by tilting the respective panels through actuation of the rake adjusters.

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

[0080] Grooves 18 are channels in the upper surfaces of panels 10a, 10b, 10c, 10d. Portions of recliners 30 that extend from panels 10a, 10b, 10c, and 10d when the support structure is in use can be inserted into grooves 18 when the support structure is stored. This allows for more compact storage of the support structure when not in use.

[0081] Each groove 18 includes a removal feature 19 that facilitates easy removal of the receiving portion of the rake adjuster 30. A golfer can insert their fingers into the removal feature 19 to pry that portion of the adjuster 30 from the groove 18. Prior to use, the golfer can remove that portion of the adjuster 30 from the groove during deployment of the support structure. The putting mat covers the groove 18 when installed so that the groove 18 does not interfere with the game setup.

[0082] Figure 1B is based on Figure 1A A close-up exploded view of the support structure 100 in an embodiment of the present invention. Figure 1BThe pump 32 and the actuatable valve 34 of the recliner 30 are more clearly shown. The recess 18 is configured to receive the pump 32, the valve 34, and the tubes 36 that connect these to the inflatable chambers. The pump 32 and valve 34 of the recliner 30 protrude from the sides of each panel when in use. The pump 32 and valve 34 are fluidly connected to the inflatable chambers (at the bottom of each panel 10a, 10b, 10c, 10d) by tubes 36. Figure 1B (Not visible in the view of FIG. 1 ). Tube 36 passes through recesses in panels 10a, 10b, 10c, 10d to reach the inflatable chambers.

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

[0084] In this embodiment, the cup 40 is an integral part of an automatic ball recovery unit and may be a commercially available unit. Figure 1B 4. In the exploded view of the support structure 100, a housing 42 of the ball recovery member (e.g., containing batteries and electronic components) is shown as 42. The ball recovery member (consisting of the cup 40 and the housing 42) is positioned within an opening 44 formed in the first panel 10a. In some embodiments, the cup 40 can be an integral part of the ball recovery member 42. The ball recovery member 42 is configured to return a golf ball to a golfer positioned at the second end 22 of the support member 20, at the end of the support structure 100 opposite the cup 40. In various embodiments, additional cups can be provided such that the device includes two or more cups.

[0085] Also shown is a retractable bumper 45 disposed at an edge of the first panel 10a closest to the first end 21 of the playing area 20. The bumper 45 is configured to prevent a golf ball traveling from the second end 22 toward the first end 21 from rolling over the edge of the first panel 10a located at the first end 21 and falling off the playing surface of the putting mat. In this embodiment, the bumper 45 extends around the edge of the panel 10a closest to the first end 21 of the playing area 20 so as to define a "C" shape. When in use, the bumper 45 protrudes outwardly from the upper surface of the panel 10a (see FIG. 2 ). Figure 2B ). When not in use, such as Figure 1B As shown, the cushioning member may be fully or partially received within a slot located in the first panel 10a for storage.

[0086] Figure 1C is an alternative view of support structure 100. Specifically, Figure 1Cis a view of the underside of the support structure 100. Each of the panels 10a, 10b, 10c, 10d includes two cavities 12, each cavity housing a plurality of inflatable chambers 36 of slope adjustment members 30. In more detail, as shown Figure 1C inflatable chambers 36a-1 and 36a-2 form part of slope adjustment members 30a-1 and 30a-2, respectively; inflatable chambers 36b-1 and 36b-2 form part of slope adjustment members 30b-1 and 30b-2, respectively; inflatable chambers 36c-1 and 36c-2 form part of slope adjustment members 30c-1 and 30c-2, respectively; and inflatable chambers 36d-1 and 36d-2 form part of slope adjustment members 30d-1 and 30d-2, respectively. Figure 1A

[0087] The cavities 12 and their respective chambers 36 are arranged off-centre of the panels to enable tilting and close to the first side edge 14 or the second side edge 16 of the panels 10a, 10b, 10c and 10d to enable tilting left / right relative to the direction of play in addition to tilting up / down. In various embodiments, the inflatable chambers of the panels can be configured to be located at the side edges of the corresponding panel in use. For example, upon deployment of the support structure, 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 the inflatable chamber 36 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, thereby causing the corresponding panel of the cavity 12 to tilt when the support structure is placed on a floor or other surface. In other words, the depth of the cavity 12 is generally comparable to the height of the uninflated inflatable chamber 36.

[0089] Each panel 10a, 10b, 10c, 10d includes two cavities 12: one of the two cavities is arranged close to the first side edge 14 of the panel 10a, 10b, 10c, 10d and the other cavity is arranged close to the second side edge 16. The inflatable chambers are positioned in these cavities off-centre of the panel, thereby enabling "left / right" tilting in addition to up / down tilting of the support from an elongate perspective. Furthermore, positioning the inflatable chambers in these cavities off-centre of the panels 10a, 10b, 10c, 10d enhances the stability of the support structure.

[0090] ​The cavities 12 of the first and second panels 10a, 10b are positioned adjacent to the first end 21 of the support structure at the first end edge, while the cavities 12 of the third and fourth panels 10c, 10d are positioned adjacent to the second end 22 of the support structure at the second end edge. Thus, an uphill profile in the court area 20 can be created by inflating the cavities of the first and second panels 10a, 10b, and a downhill profile in the court area 20 can be created by inflating the cavities of the third and fourth panels 10c, 10d. Multiple pitch adjustment elements positioned across the support structure advantageously enable the creation of multiple, complex pitch profiles. For example, a flat, then downhill profile can be created in the court area 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. Thus, by equally 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, a flat and then uphill profile can be created in the playing area.

[0091] Figure 1D is a further close-up view of the underside of the support structure 100. Figure 1D As shown, the shape of the inflatable chamber 36 is substantially the same as the opening of the cavity 12. The chambers 36 are fixed to their respective cavities using screws and rivets. Alternatively, the chambers can be fixed to the cavity 12 by interference fit or by other means (such as a locking mechanism). Figure 1C and Figure 1D Also shown are a number of circular cavities 80 on the underside of the panels forming the support structure. These cavities advantageously minimize the weight of the support, thereby improving portability.

[0092] Figure 2A Schematic diagram of the push rod device 200 in the embodiment of the present invention. The push rod device 200 includes the above reference Figures 1A to 1D The support structure 100 and the pitch adjustment members described herein, along with a putting layer in the form of a putting mat 50 disposed on the playing area 20 of the support structure 100, are described. The putting mat 50 extends across the playing area from a first end 21 to a second end 22 to define a playing surface 51 that follows the adjustable contour of the underlying support structure 100. The putting mat smoothes any edges between adjacent panels of the underlying support structure and provides a smooth playing surface. The preferred playing direction PD is defined as running from the second end 22 to the first end 21. Thus, a user of the putting device 200 can adjust the pitch of the playing surface 51 using multiple pitch adjustments to create a challenging yet realistic contour along the playing direction PD. Specifically, the pitch adjustments can be actuated to create multiple pitches along the playing direction, mimicking a real putting green. However, if desired, a single constant pitch can be achieved through appropriate actuation of the pitch adjustments.

[0093] For example, the inflation of the inflatable chambers of the inclination adjusting members 30a-1, 30b-1, 30c-1 and 30d-1 can cause the corresponding panel to tilt downward to the left from the angle of the playing direction, producing a "right to left turn" push. On the contrary, the inflation of the inflatable chambers of the inclination adjusting members 30a-2, 30b-2, 30c-2 and 30d-2 can cause the corresponding panel to tilt downward to the right from the angle of the playing direction, producing a "left to right" turn push. Uphill and downhill tilt putts can also be established based on the relative actuation of the inclination adjusting members at the first and second ends of the support structure. Typically, multiple inclination adjusting members allow the court surface 51 to tilt in two non-parallel directions (e.g., tilted perpendicular to the playing direction and tilted parallel to the playing direction). The connection of the panel via the tension hinge produces smooth, lifelike contour changes on the entire court surface 51. As described, because the panels are flexibly connected with tension hinges, operating a single rake adjuster 30 can cause its corresponding panel and adjacent panels to tilt. This advantageously creates a rake profile in the playing surface that is not limited to the rake adjuster being operated.

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

[0095] exist Figure 3A , the first configuration described is an uphill putting configuration. In the 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 playing 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 is a downhill putting configuration. In the second configuration, the inflatable chambers 36d-2 and 36d-1 of panel 10d are inflated to a greater degree than the inflatable chambers 36c-1 and 36c-2 of panel 10c to create a downhill profile on the playing 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 3C, the third configuration described is a "humpback" putter configuration. In this third configuration, inflatable chambers 36b-2 and 36b-1 of panel 10b and inflatable chambers 36c-2 and 36c-1 of panel 10c form a raised profile on the playing surface. These chambers are inflated to a greater degree than chambers 36a-2 and 36a-1 of panel 10a and chambers 36d-2 and 36d-1 of panel 10d. Therefore, due to the inflation of inflatable chambers 36b-2 and 36b-1 and 36c-2 and 36c-1 and the tension hinge, panels 10a and 10b also tilt, but to a lesser degree than panels 10b and 10c.

[0098] exist Figure 3D In FIG, the fourth configuration depicted is an uphill, left-to-right push configuration. This fourth configuration can be achieved, for example, by inflating the inflatable chambers 30a-2 and 30b-2 to directly adjust the slope of the panels 10a and 10b appropriately. Figure 3D In the particular profile shown, inflatable chamber 30a-2 is inflated to a greater extent than inflatable chamber 30b-2.

[0099] It should be noted that in the above example, the tension hinge connecting panels 10a and 10b opens in a first direction, and the tension hinge connecting panels 10b and 10c opens in the opposite direction. The hinge connecting panels 10c and 10d is installed in the same configuration as the hinge connecting panels 10a and 10b. Figure 3A and Figure 3B In the scenario of , the surface between panels 10b and 10c remains generally planar (because the hinge generally does not open more than 180 degrees), but in Figure 3C The "hunchback" outline is achieved in the scene shown. Figure 3C , although panels 10a and 10b are substantially coplanar due to the configuration of the tension hinge connecting them, the hinge can be opened slightly beyond 180 degrees to provide a more gradual change in profile as shown. This can also be seen in the connection between panels 10c and 10d. In a preferred embodiment, as described above, the direction in which the hinge sets close can alternate for the respective panel pairs. This configuration of the hinge can provide for ease of folding (described later), but it is contemplated that different hinge configurations can be used to achieve different slope profiles.

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

[0101] The putter pad 50 is preferably removably attached to the support structure 100, for example via fastening means such as flat head bolts or screws, Or carpet clips. The push rod pads can be produced using techniques known in the art.

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

[0103] Figure 2B 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, but with the putting mat 50 installed, covers the connector 60, the groove 18, the interface between the panels and the ball recovery housing 42, thus creating a smooth playing surface. In addition, although Figure 1B The bumper 45 is shown in its retracted position, but Figure 2B Bumper 45 is shown in its protruding position, whereby bumper 45 is configured to prevent golf ball 90 from rolling off putter device 200 if it misses cup 40 .

[0104] Figure 2C is based on Figure 2A A partially exploded view of a 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 gasket 55 that at least partially covers the chamfered end 70. Figure 2AIn addition to the features described in relation to the embodiments, Figure 2C The mat cover 55 is depicted removed from the fourth panel 10d. As described above, the putting mat 50 is removably attached to the support structure 100, thereby allowing different mats to be used. Typically, the panels are sized so that the court area 20 has a longer length (in the direction of play) than the putting mat 50, and different mats can have different lengths within manufacturing tolerances. When the putting mat is installed, the mat can be positioned in the correct position under the mat cover 55 at the second end to ensure that the hole 52 in the putting mat 50 remains aligned with the opening of the cup 40 when the putting device 200 is in use because the mat can be clamped in the correct position under the mat cover 55. The chamfered end 70 allows the mat cover 55 to be mounted at the same height as the court surface 51 so that the golfer's swing will not be a foul. However, in alternative embodiments, the putting device may not include the chamfered end 70 and the mat cover 55 (e.g., as Figure 3D In such an alternative embodiment, the fasteners used to attach the putting pad to the support structure may be adjustable (e.g., adjustable mechanical clamps) to accommodate putting pads of varying lengths (e.g., within manufacturing tolerances).

[0105] Figure 4A This is an exploded schematic diagram 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 and lower plates 62 and 64 are connected by a plurality of support columns 68 disposed between the upper and lower plates to secure the two plates. Furthermore, a tension member 69 is disposed between the upper and lower plates 62 and 64.

[0106] The upper plate 62 is provided with two (e.g. equal-sized) parts 62a, 62b. Similarly, the lower plate 64 is provided with two parts 64a, 64b. The upper and lower plates may be formed of a suitable material, such as plastic. The upper plate part 62a and the lower plate part 64a form a first section of the connector 60, and the upper plate part 62b and the lower plate part 64b form a second section of the connector 60. The tension member 69 connects the two sections of the tension hinge and allows a certain degree of free articulation between the first and second sections of the connector. Thus, the connector 60 acts as a tension hinge, wherein the tension generated by the tension member 69 generates a force that causes the hinge to be pushed to the Figure 4AThe upper panel 62 includes a hinge (shown at 160) (e.g., polypropylene) which facilitates the pivoting of the connector 60. Here, the upper panel 62 includes a "living" hinge which is an integral part of a single upper panel. However, other types of hinge components may be utilized to achieve pivoting of the tension hinge. When the hinge 60 is in a position such as Figure 4A When in the open position shown, the connected panels will lie in the same plane.

[0107] In this embodiment, tension member 69 comprises a portion of an elastic cord (e.g., a "bungee cord"). In alternative embodiments, the tension member may comprise a spring or other material suitable for forming an extendable tension member. The tension of tension member 69 is selected so that when a first panel is tilted by inflation of its corresponding inflatable chamber, a directly connected panel (which is not directly tilted by the inflatable chamber) is partially tilted. In a preferred embodiment, the adjacent panel tilts to a lesser degree than the first panel, but the adjacent panel does not fail to tilt when the first panel tilts.

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

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

[0110] While Scenario 1 provides multi-planar interruption due to the flexible connection between the two panels, it is a less ideal arrangement than Scenario 2 because the gradient of the playing surface changes more abruptly when the panels are tilted. This is less similar to the contour of the green than the gradually increasing gradient between adjacent panels depicted in Scenario 2.

[0111] The tension of the elastic member should be selected to enable the user to fold the panel from about 180° to the folded position, such as Figure 5As shown. In various embodiments, the tension hinge 60 may close in one direction but not the other. In other words, the hinge may not open through an angle significantly greater than 180 degrees. The tension hinge may open through a small range of angles greater than 180 degrees (e.g., up to about 10 degrees at most), for example, to prevent accidental breaking. The tension hinge 60 may be disposed between different pairs of panels in an opposing configuration to facilitate folding of adjacent panels in different directions. For example, the connectors for the end panels may only allow the end panels to fold inwardly, while the connectors for the middle panels may only allow the middle panels to fold outwardly. For example, the connector or connectors 60 may be disposed in a manner similar to that of FIG. Figure 4B The closing direction of the connector or connector group can be reversed for each panel pair. This allows for easy folding of the push rod device and also allows for different configurations of the outer contour.

[0112] Figure 5 is a schematic diagram of the support structure 100 of the push rod device in a folded configuration. In this configuration, the support structure 100 can be advantageously stored compactly (e.g., by first removing the push rod pad). Features such as the rake adjustment members are completely stored in the cavities and recesses of their corresponding panels (as described above), and thus the panels 10a, 10b, 10c, and 10d can be folded to be flush with each other. As described above, the connector 60 operates as a hinge, which articulates 180 degrees. Therefore, the panels 10a, 10b, 10c, and 10d do not need to be disassembled from each other when the support structure is stored.

[0113] The above embodiments describe a putting device comprising four connected panels, each panel being in communication with two tilt adjustment members. However, it should be understood that other configurations may be used. For example, the support structure may include fewer than four panels or more than four panels. Furthermore, while the configuration in which each panel is in communication with two tilt adjustment members advantageously enhances control of the pitch of the playing surface and improves the stability of the device, it is contemplated that in some embodiments, only a portion of the panels may include tilt adjustment members. In some scenarios, it is contemplated that the support structure may include only a single tilt adjustment member.
