DETAILED DESCRIPTION OF THE INVENTION
[0005] First, referring to FIG. 1, an exemplary machine tool 100 is shown, with one floor plate 102 removed, exposing a floor opening, i.e., a cavity 104. FIG. 2 schematically shows a modular machine tool plate lifter system 10 for assembling a machine tool plate lifter 12 as shown in FIGS. 3 - 5, for example. The system is used to functionally lift the floor plate 102 of the machine tool 100 above other adjacent floor plates 102.
[0006] As schematically shown in FIG. 2, the modular machine tool plate lifter system 10 includes a plurality of lifter panels 14. FIG. 2 schematically shows four lifter panels 14, but the modular machine tool plate lifter system 10 may include any number of lifter panels 14. As schematically shown in the same figure, each lifter panel 14 includes a first panel portion 16 having a first panel portion outer edge region 18, and a second panel portion 20 slidably connected to the first panel portion 16 and having a second panel portion outer edge region 22 located on the opposite side of the first panel portion outer edge region 18. The first panel portion outer edge region 18 of each lifter panel 14 is configured to be selectively connectable to the second panel portion outer edge region 22 of other lifter panels 14. Thus, a selected lifter panel 14 from the machine tool plate lifter system 10 is functionally configured to be assembled to form a polygonal (e.g., matching the polygon of the floor opening or the floor plate to be lifted) machine tool plate lifter 12 such as the exemplary machine tool plate lifter 12 schematically shown in FIGS. 3 - 5. In some examples, the lengths of the first panel portion 16 and the second panel portion 20 are substantially the same.
[0007] In some examples, the outer edge region 18 of the first panel portion of each riser panel 14 is configured to be selectively connectable to the outer edge region 22 of the second panel portion of other riser panels 14 at various angles. Thus, various polygons can be formed using the selected riser panels 14. As a result, the present system is configured to be able to appropriately construct floorboard risers according to the specific shape of the floor opening or the floorboard to be lifted, for example, shapes such as a triangle (illustrated in FIG. 3), a square (illustrated in FIG. 4), a rectangle (illustrated in FIG. 5), etc. In other examples, the outer edge region 18 of the first panel portion of each riser panel 14 is configured to be selectively connectable to the outer edge region 22 of the second panel portion of other riser panels 14 at a single angle such as a right angle (90°). In these examples, only specific polygons can be formed. In the case of riser panels 14 where the angle between adjacent connected riser panels 14 is limited to a right angle, such as the floorboard risers illustrated in FIGS. 4 and 5, the shape formed is a right-angled quadrilateral. Such examples are suitable for designs consisting only of square or rectangular floorboards.
[0008] Referring to FIG. 6, the riser panel 14 of the aircraft floorboard riser system 10 is schematically shown. Generally, in FIG. 6, elements that are likely to be included in a certain embodiment are shown in solid lines, and elements that are optional in a certain embodiment or correspond to a specific embodiment are shown in dashed lines. However, it is not the case that the elements shown in solid lines are essential in all embodiments of the present disclosure, and it is also possible to omit the elements shown in solid lines from a specific embodiment without departing from the scope of the present disclosure.
[0009] As schematically shown in FIG. 6 and as described above, each riser panel 14 includes at least a first panel portion 16 and a second panel portion 20 slidably connected to the first panel portion 16. In some examples, each riser panel 14 further includes a clamp 24 configured to selectively secure the second panel portion 20 to the first panel portion 16. Thus, when assembling the aircraft floorboard riser 12, the overall length of the riser panel 14 is selected according to the actual use of the riser panel 14. In some of such examples, the first panel portion 16 has a first partial longitudinal channel 26, the second panel portion 20 has a second partial longitudinal channel 28 parallel to the first partial longitudinal channel 26, and the clamp 24 passes through the first partial longitudinal channel 26 and the second partial longitudinal channel 28 and engages the opposite surfaces of the first panel portion 16 and the second panel portion 20. As an example, the clamp 24 may include a cam lever assembly 30 to facilitate adjustment of the overall length of the riser panel 14 by a technician. However, other configurations may be employed for the clamp 24.
[0010] As schematically shown in FIG. 6, in some examples, the first panel portion 16 includes a planar first portion body 32 that is substantially parallel to the second panel portion 20, and a first portion lower ledge 34 that extends at a right angle from the first portion body 32 and extends below the second panel portion 20. As used herein, "substantially parallel" means that the angle between them is within 10°. The first portion lower ledge 34 is configured to contact the upper surface of an adjacent floorboard 102 (see, e.g., FIG. 16) when the aircraft floorboard lifter 12 is functionally installed. In some such examples, the first portion lower ledge 34 extends along substantially the entire length of the first portion body 32. Thus, when the aircraft floorboard lifter 12 is functionally installed, the substantial length portion of the first portion body 32 is directly supported by the first portion lower ledge 34 and the upper surface of the floorboard 102. Further, in an example where the lengths of the first panel portion 16 and the second panel portion 20 are substantially the same, due to the overlap between the first panel portion 16 and the second panel portion 20, the first portion lower ledge 34 extends beyond 50% of the total length of the lifter panel 14. As a result, the lifter panel 14 as described above is securely supported on the floorboard 102 when functionally installed.
[0011] Continuing to refer to FIG. 6, in some examples, the first panel portion 16 includes the first portion body 32 and an elongated tab 36 that extends downward and parallel to the first portion body 32. In such an example, the elongated tab 36 is configured to contact one edge of an adjacent floorboard 102 when the aircraft floorboard lifter 12 is functionally installed. In some examples where the first panel portion 16 further includes the first portion lower ledge 34, the first portion lower ledge 34 and the elongated tab 36 are integrated with each other and are functionally connected to the first portion body 32. As an example, the first portion lower ledge 34 and the elongated tab 36 may constitute a T-shaped extrusion member 38 that is functionally connected to the first portion body 32.
[0012] In some examples, the first panel portion 16 includes a first portion body 32 and an upper ledge 40 that extends perpendicularly from the first portion body 32. In such examples, the upper ledge 40 is configured to contact and support the floorboard 102 to be lifted. In some examples where the first panel portion 16 further includes a first portion lower ledge 34, the upper ledge 40 and the first portion lower ledge 34 extend from opposite faces of the first portion body 32, and the upper ledge 40 is spatially located above the first portion lower ledge 34. Thus, the first portion lower ledge 34 extends outwardly from the assembled aircraft floorboard lifter 12 and contacts an adjacent floorboard 102, and the upper ledge 40 extends inwardly from the assembled aircraft floorboard lifter 12 and supports the floorboard 102 to be lifted above the surface of the adjacent floorboard 102.
[0013] As schematically shown in FIG. 6, in some examples, the first portion body 32 can be described as including a first portion upper edge 42, and the upper ledge 40 extends from the first portion body 32 below the first portion upper edge 42. Thus, when the floorboard 102 to be lifted is functionally disposed on the assembled aircraft floorboard lifter 12, it is supported on the upper ledge 40 and is constrained by the first portion body 32 so as not to translate outwardly from the desired position. That is, the first portion body 32 serves to prevent the lifted floorboard 102 from slipping down from the desired position above the cavity 104 of the aircraft floor 100.
[0014] In some examples, the upper ledge 40 extends along a substantial length of the first portion body 32. Thus, when the aircraft floorboard lifter 12 is functionally installed, a substantial length portion of the lifted floorboard 102 is directly supported by the upper ledge 40. Further, in examples where the lengths of the first panel portion 16 and the second panel portion 20 are substantially the same, due to the overlap between the first panel portion 16 and the second panel portion 20, the upper ledge 40 extends beyond 50% of the total length of the lifter panel 14. As a result, the lifter panel 14 as described above can reliably support the lifted floorboard 102.
[0015] As schematically shown in FIG. 6, in some examples, the first part body 32 can be described as including a first part inner edge 44, which is located on the opposite side of the outer edge region 18 of the first panel part and overlaps the second panel part 20. In such an example, the upper ledge 40 can extend to the first part inner edge 44. That is, in such an example, the upper ledge 40 extends as far as possible toward the outer edge region 22 of the second panel part in order to firmly support the lifted floorboard 102.
[0016] Continuing to refer to FIG. 6, in some examples, the first part body 32 has a first part finger slit 46 extending from the upper edge 42 of the first part. Similarly, in some examples, the second part body 50 of the second panel part 20 has a second part finger slit 54 extending from the upper edge 52 of the second part body 50. When providing the first part finger slit 46 and / or the second part finger slit 54, the dimensions of these slits are such that with the lifted floorboard 102 being supported by the assembled aircraft floorboard lifter 12, a user can insert a finger into these slits and contact the underside of the floorboard 102, for example, to lift and remove this floorboard.
[0017] As schematically shown in FIG. 6, in some examples, the first panel part 16 includes a first part handle 48 extending upward from the upper edge 42 of the first part. Similarly, in some examples, the second panel part 20 includes a second part handle 56 extending upward from the upper edge 52 of the second part. In examples where the first part handle 48 and / or the second part handle 56 are provided, these handles are configured to be selectively grippable by a user in order to functionally position the aircraft floorboard lifter 12 in processes such as the assembly and placement of the aircraft floorboard lifter 12.
[0018] Continuing to refer to FIG. 6, in some examples of the floor panel riser 14, the first panel portion outer edge region 18 includes a first panel portion fitting structure 58, and the second panel portion outer edge region 22 includes a second panel portion fitting structure 60 configured to fit with the first panel portion fitting structure 58 of another riser panel 14 for functionally assembling the aircraft floor panel riser 12. In some such examples, the second panel portion fitting structure 60 fits with the first panel portion fitting structure 58 of another riser panel 14, and in so doing, is configured to fit with the first panel portion fitting structure 58 at a single angular orientation, such as 90°, for example. As described above and as schematically shown in the examples of FIGS. 4 and 5, the aircraft floor panel riser 12 can form a right-angled quadrilateral. In other examples, the second panel portion fitting structure 60 fits with the first panel portion fitting structure 58 of another riser panel 14, and in so doing, is configured to fit with the first panel portion fitting structure 58 at a plurality of angular orientations, thereby enabling the assembly of various polygonal-shaped aircraft floor panel risers 12.
[0019] In some examples, as schematically shown in FIG. 6, one of the first panel portion fitting structure 58 or the second panel portion fitting structure 60 includes a long bar member 62, and the other of the first panel portion fitting structure 58 or the second panel portion fitting structure 60 includes an elongated slot 64 configured to receive the long bar member 62 of another riser panel 14. In some such examples, the first panel portion fitting structure 58 and the second panel portion fitting structure 60 of adjacent riser panels 14 form a hinge. In some examples, the long bar member 62 has a shape such that it does not rotate or pivot within the elongated slot 64.
[0020] Continuing to refer to FIG. 6, in some examples, the first panel portion 16 includes a first partial hole 66, and the second panel portion 20 includes a second partial hole 68, which is configured to be aligned in a row when functionally coupled with the first partial hole 66 of another riser panel 14. In such examples, the modular aircraft floorboard riser system 10 further includes a plurality of pins 74, each pin 74 being configured to selectively penetrate these partial holes when the first partial hole 66 of the riser panel 14 and the second partial hole 68 of another riser panel 14 are functionally coupled. In some of such examples, the pins 74 functionally hold the pins once inserted into the first partial hole 66 and the second partial hole 68 of adjacent riser panels 14, and can be configured to have a detent, spring, and / or other structure that can selectively remove the pin 74 when, for example, a user applies a force exceeding a threshold value to the pin 74. As a result, the pins 74 can prevent the adjacent riser panels 14 from inadvertently separating until the user chooses to disassemble the assembled aircraft floorboard riser 12.
[0021] As schematically shown in FIG. 6, in some examples, the outer edge region 22 of the second panel portion includes a reinforcing region 70 that is thicker than the adjacent region of the second panel portion 20. In such examples, the reinforcing region 70 provides additional material to support the interface between two adjacent riser panels 14 when the aircraft floorboard riser 12 is assembled and used, for example, when someone stands on the floorboard 102 lifted by the aircraft floorboard riser 12. Also, in some of such examples, the second partial hole 68 penetrates the reinforcing region 70. That is, the reinforcing region 70 provides a material having a given thickness, enabling the second partial hole 68 to be included in the riser panel 14 without the entire second panel portion 20 requiring such thickness.
[0022] Continuing to refer to FIG. 6, in some examples, the second panel portion 20 includes a second lower ledge 72 that extends at a right angle in a direction opposite to the first panel portion 16 from the second portion body 50 within the second panel portion outer edge region 22. In such examples, similar to the first lower ledge 34, the second lower ledge 72 is configured to contact the upper surface of the adjacent floorboard 102 when the aircraft floorboard lifter 12 is functionally installed. In some of such examples, the second lower ledge 72 is aligned with the first lower ledge 34. In some examples, the second lower ledge 72 is included in the reinforcement region 70.
[0023] As also schematically shown in FIG. 6, in some examples, the second panel portion 20 includes a second portion tab 76 that extends downward and parallel to the second portion body 50. In examples where the second portion tab 76 is provided, the tab is configured to contact the edge of the adjacent floorboard 102 when the aircraft floorboard lifter 12 is functionally installed. In some of such examples, the second portion tab 76 is aligned with the elongated tab 36. In some examples, the second portion tab 76 is included in the reinforcement region 70.
[0024] Referring now to FIGS. 7-14, an exemplary and non-exclusive example of the riser panel 14 is shown in the form of a riser panel 140. FIGS. 15 and 16 show how four riser panels 140 are functionally assembled to form an aircraft floor panel lifter 12 for lifting the floor panel 102. By appropriately using the reference numerals used in the schematic diagram of FIG. 6, corresponding parts of the riser panel 140 are shown, but the examples of FIGS. 7-14 are non-exclusive and do not limit the riser panel 14 to the embodiments of the riser panel 140. That is, the riser panel 14 is not limited to the specific embodiments of the illustrated riser panel 140, and these riser panels 14 can include any of the various aspects, configurations, features, characteristics, etc. of the riser panel 14 illustrated and described with reference to FIG. 6, and / or the embodiments shown in FIGS. 7-14, as well as modifications thereof, and in that case, it is not necessary to include all of these aspects, configurations, features, characteristics, etc. For the sake of brevity, the above-described components, parts, portions, aspects, regions, etc., or modifications thereof may not be described, illustrated, and / or labeled again in association with the riser panel 140. However, using the above-described features and modifications, etc. together with the riser panel 140 is within the scope of the present disclosure.
[0025] As shown in the illustration, riser panel 140 is an example of riser panel 14. The first panel portion 16 has a first partial longitudinal channel 26, and the second panel portion 20 has a second partial longitudinal channel 28. The riser panel 140 includes a clamp 24 that passes through the first partial longitudinal channel 26 and the second partial longitudinal channel 28 and includes a cam lever assembly 30. The first panel portion 16 of the riser panel 140 includes a T-shaped extrusion member 38 having a first partial lower ledge 34 and an elongate tab 36, both of which extend along a substantial length of the first partial body 32. The first panel portion 16 of the riser panel 140 further includes an upper ledge 40, which is provided on the opposite side of the first partial body 32 from the first partial lower ledge 34 and spatially above this lower ledge, and extends over a substantial length of the first partial body 32. The first panel portion 16 includes a first partial handle 48, and the first partial body 32 has a first partial finger slit 46. The second panel portion 20 of the riser panel 140 includes a second partial handle 56. The first panel portion fitting structure 58 includes an elongate bar member 62, and the second panel portion fitting structure 60 includes an elongate slot 64. As perhaps most clearly shown in FIG. 8, the second panel portion 20 includes a reinforcing region 70 having a second partial hole 68 and a second partial tab 76 aligned with the elongate tab 36 of the first panel portion 16. The first panel portion 16 has a corresponding first partial hole 66, and the first partial hole 66 and the second partial hole 68 are sized to receive an associated pin 74.
[0026] As shown in FIGS. 15 and 16, four riser panels 140 can be functionally assembled to form an aircraft floorboard riser 12 that can functionally lift the floorboard 102 above an adjacent floorboard. Specifically, this lifting operation is achieved by the assembled aircraft floorboard riser fitting within the floor opening in which the floorboard 102 is disposed and supporting the floorboard 102 above it.
[0027] FIG. 17 schematically shows a flowchart illustrating an exemplary and non-exclusive example of method 200 according to the present disclosure. In FIG. 17, some steps are shown in dashed boxes, and the dashed lines indicate that these steps are optional or correspond to any aspect of the method according to the present disclosure. However, not all methods according to the present disclosure necessarily include the steps shown in solid boxes. The methods and steps shown in FIG. 17 are not limiting, and other methods and steps, including those with more or fewer steps than those illustrated, are within the scope of the present disclosure as understood from the description herein.
[0028] As schematically shown in FIG. 17, method 200 includes removing at least the floorboard 102 to be lifted in the aircraft tool 100 to form the cavity 104 (202), and subsequently, functionally arranging the aircraft floorboard lifter 12 to engage with the floorboard 102 adjacent to the cavity 104 (204), and then functionally arranging the floorboard 102 to be lifted onto the aircraft floorboard lifter 12 (206). Some methods 200 further include assembling the aircraft floorboard lifter 12 from the modular aircraft floorboard lifter system 10 according to the present disclosure (208).
