Description

Technical Field

[0001] This invention relates to the field of resistance training technology, specifically a resistance training device with power generation function. Background Art

[0002] Resistance training is a form of exercise that improves muscle strength and endurance. During resistance training, the limbs resist the resistance generated by body weight, gravity, resistance bands, or weightlifting. In strength training, barbells are often used to add resistance and induce muscle contraction, thereby increasing strength.

[0003] Most existing resistance training equipment, when used, simply dissipates energy as heat during resistance training with barbells, without generating or storing energy, resulting in the unnecessary loss and waste of energy. Summary of the Invention

[0004] The purpose of this invention is to provide an impedance training device with power generation function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The resistance training device with power generation function includes a housing, a support frame installed outside the housing, a sliding rod installed on the support frame, a movable sleeve installed on the sliding rod, multiple barbell plates on the support frame, and the movable sleeve connected to the uppermost barbell plate. The support frame has symmetrically symmetrically opened weight holes. A first pulley and a second pulley are symmetrically installed on the housing. Both ends of the uppermost barbell plate are connected to the first and second pulleys via ropes, which pass through the weight holes. The housing has symmetrically opened rope inlet holes. Generators are symmetrically installed vertically inside the housing, and each of the two generators has a symmetrically installed generator flywheel. The rope passes through the rope inlet holes and wraps around the generator flywheel. An energy storage device is installed outside the housing, and the generator's output terminal is connected to the energy storage device. The box is connected by a wire, and a rope outlet hole is opened at the bottom of the box. An external plate is installed on the side of the box near the support, and a pulley groove is opened on the external plate. A third pulley is installed in the pulley groove. The rope passes through the rope outlet hole and is wound around the third pulley. A placement rack is installed on the same side of the box, and a barbell bar is placed on the placement rack. The end of the rope is tied to the barbell bar. When performing resistance training, the user pulls the barbell bar to drive the barbell plates to move longitudinally back and forth, causing the rope wrapped around the generator flywheel to move back and forth, thereby driving the generator flywheel to rotate, and thus causing the generator to generate electricity. The generated electricity can be stored in the storage box, and can also be used to charge personal electronic devices through the charging unit, thereby converting mechanical energy into electrical energy and reducing energy loss.

[0006] As a preferred technical solution, the housing is provided with an oil injection assembly, and the first pulley provides the rotational driving force for the oil injection assembly.

[0007] As a preferred technical solution, the oil injection assembly includes an oil injection housing, an oil injection chamber, a piston, an oil reservoir, an oil inlet pipe, an oil injection pipe, a slide groove, a slider, a connecting rod, a connecting pipe, a brush tube, a first belt, a support frame, a central rod, a cam, an outer frame, and a moving rod.

[0008] An external rod is installed at the center of one side of the first pulley. Two support frames are installed on the housing. A first pulley is installed on the external rod. A central rod is rotatably installed on the two support frames, and the two support frames are connected by the central rod. A second pulley is installed on the central rod. The first pulley and the second pulley are connected by a first belt. A cam is installed on the central rod. An oil filling housing is installed on the housing. The oil filling housing has symmetrical through holes at both ends. The rope passes through the two through holes and enters the oil filling housing. An oil filling chamber is provided inside the oil filling housing. An oil storage tank is installed outside the oil filling housing. The oil filling chamber and the oil storage tank are connected by an oil inlet pipe. A piston is slidably installed inside the oil filling chamber. A moving rod is installed on the piston. A connecting hole is opened on the oil filling chamber. The moving rod passes through the connecting hole and has an outer frame installed at its end. The cam... Located within the outer frame, the outer contour of the cam contacts the inner side of the outer frame. A groove is provided on the top of the oil filling housing, and a slider is slidably installed within the groove. A connecting rod is installed at the bottom of the slider, and a connecting pipe is installed at the bottom of the connecting rod. The connecting pipe is connected to the oil filling chamber via an oil filling pipe. Brush tubes are installed at the bottom of both ends of the connecting pipe, and a rope passes through the brush tubes. During resistance training, the user pulls the rope, causing it to reciprocate. This reciprocating motion causes friction to rotate the first pulley, which in turn rotates the central rod via the outer connecting rod and the first belt. The central rod then rotates the cam and the rotating wheel, causing the cam to push the outer frame in a lateral reciprocating motion. This, in turn, causes the piston to reciprocate via the moving rod. As the piston reciprocates, due to the suction effect, lubricating oil enters the oil filling chamber from the oil inlet pipe and is discharged into the connecting pipe via the oil filling pipe, thus filling the brush tubes with oil.

[0009] As a preferred technical solution, the oil injection assembly further includes a connecting column, a moving block, a moving groove, an external rod, a rotating wheel, a circumferential plate, a connecting plate, and a second belt;

[0010] A pulley is mounted on the end of the central rod away from the first belt. A fixing pin is fixedly mounted on the pulley, and a circumferential plate is rotatably mounted on the fixing pin. A connecting pin is mounted on the end of the circumferential plate away from the pulley, and a connecting plate is rotatably mounted on the connecting pin. A movable groove is formed on the side of the oil filling housing near the connecting plate, and a movable block is installed in the movable groove. The movable block is connected to the connecting plate, and the side of the movable block away from the connecting plate is connected to the connecting pipe through a connecting post. A belt groove is formed on the housing at the bottom of the pulley. The pulley on the housing connects to the belt groove inside the housing. The rotating wheel is connected by a second belt that passes through a belt groove. During resistance training, the rotating wheel causes the moving block to reciprocate within the moving groove via a circumferential plate and a connecting plate, which in turn drives the brush tube to reciprocate, ensuring full contact between the brush tube and the rope. This allows for the application of lubricating oil to the rope, reducing friction between the rope and the pulley system. This ensures that the user experiences a tension equal to the weight of the preset barbell plates during resistance training, minimizing energy loss. The second belt also causes the rotating wheel inside the box to rotate, which in turn causes the piston and brush tube inside the box to move, thus achieving synchronous oil injection.

[0011] As a preferred technical solution, the oil injection assembly further includes an oil suction pipe and an oil return pipe. The bottom of the brush tube is connected to the end of the oil injection chamber away from the oil injection pipe through the oil suction pipe, and the end of the oil injection chamber away from the oil inlet pipe is connected to the oil storage tank through the oil return pipe. When oil injection is performed, excess lubricating oil is deposited at the bottom of the brush tube. When the piston reciprocates, due to the suction effect, excess lubricating oil flows back to the oil injection chamber through the oil suction pipe and returns to the oil storage tank through the oil return pipe, thereby realizing the recycling and reuse of excess lubricating oil.

[0012] As a preferred technical solution, the oil inlet pipe, oil injection pipe, oil suction pipe and oil return pipe are all unidirectional pipes.

[0013] As a preferred technical solution, the first pulley is a ratchet, and the housing and oil filling housing are provided with self-locking components.

[0014] As a preferred technical solution, the self-locking assembly includes a through groove, a fixed shaft, a pawl, and an electric telescopic rod;

[0015] An adjuster is installed inside the barbell plates. Electric telescopic rods are symmetrically installed on the top of the housing. A through groove is symmetrically opened at one end of the housing near the first pulley. A fixed shaft is installed in the through groove, and a pawl is rotatably mounted on the fixed shaft. One end of the pawl engages with the first pulley, and the other end is located on the center line of the electric telescopic rod. The electric telescopic rod is electrically connected to the adjuster. When adjusting the weight, the adjuster detects the change in the number of barbell plates and controls the extension of the electric telescopic rod, causing the telescopic end of the electric telescopic rod to abut against one end of the pawl, so that the other end of the pawl fully engages and locks with the first pulley, achieving a preliminary self-locking effect.

[0016] As a preferred technical solution, the self-locking assembly further includes an electric push-pull rod, a connecting body, an outer ring, an outer groove, a connecting shaft, a locking plate, an inner ring, and an inner groove;

[0017] The oil filling housing is symmetrically fixed with inner rings, which are concentric with the through holes on the oil filling housing. Multiple inner grooves are evenly distributed on the inner rings, and connecting shafts are slidably installed within these grooves. Multiple locking plates are also slidably installed on the inner rings. Electric push-pull rods are symmetrically installed on the side of the oil filling housing closest to the inner rings. A connecting body is rotatably installed on the telescopic end of the electric push-pull rod, and an outer ring is rotatably installed on the connecting body. Multiple outer grooves are evenly distributed on the outer rings, and connecting holes are provided on each locking plate. Multiple connecting shafts pass through these connecting holes and are slidably installed within the outer grooves. The electric push-pull rods are electrically connected to an adjuster. When adjusting the weight, the adjuster controls the electric push-pull rods to retract, causing the outer rings to rotate. The outer rings, through the connecting shafts, drive the locking plates to move, thereby squeezing the rope and increasing the friction on the rope. This further enhances the self-locking effect, preventing accidental rope pulling and potential safety hazards when adjusting the weight.

[0018] As a preferred technical solution, clamps are symmetrically installed on the outside of the pulley groove, and rotating pins are installed on both clamps. An oil-absorbing sleeve is installed at the end of each rotating pin, and the rope passes through the oil-absorbing sleeve. An oil storage tank is installed on the barbell plate, and an oil storage sleeve is also installed on the barbell plate. The rope passes through the oil-absorbing sleeve and the oil storage tank. A storage slot is installed outside the housing, and a buffer pad is installed between the barbell plate and the support. During resistance training, the rope, installed inside the oil storage tank, prevents excess lubricating oil from dripping onto the barbell plate during retraction. The rope, passing through the oil-absorbing sleeve, prevents excess lubricating oil from dripping onto the outer plate during stretching, thus protecting the components. When training ends, the buffer pad effectively reduces the impact of the barbell plate on the support, achieving the same protective effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When performing resistance training, users can pull the barbell bar to move the barbell plates longitudinally back and forth, causing the rope to drive the generator flywheel to rotate, thereby generating electricity and converting mechanical energy into electrical energy, reducing energy loss.

[0021] 2. When performing resistance training, the lubrication component can apply lubricant to the rope to reduce friction between the rope and the pulley, ensuring that the user experiences the preset weight of the barbell plates during resistance training, thus reducing energy loss.

[0022] 3. When adjusting the weight of the object, the regulator operates and uses a self-locking component to lock itself, preventing accidental pulling of the rope when changing the weight and causing safety hazards. Attached Figure Description

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example: Figures 1-7 and Figure 9As shown, this invention provides a technical solution for a resistance training device with power generation function. This resistance training device includes a housing 1, a support 2 mounted outside the housing 1, a sliding rod 4 mounted on the support 2, a movable sleeve 5 mounted on the sliding rod 4, multiple barbell plates 3 mounted on the support 2, and the movable sleeve 5 connected to the uppermost barbell plate 3. The support 2 has symmetrically symmetrically arranged weight holes. A first pulley 7 and a second pulley 8 are symmetrically mounted on the housing 1. Both ends of the uppermost barbell plate 3 are connected to the first pulley 7 and the second pulley 8 via ropes 6, which pass through the weight holes. The housing 1 has symmetrically arranged rope inlet holes. Generators 9 are symmetrically mounted vertically inside the housing 1, and each generator 9 has a symmetrically mounted generator flywheel 10. The ropes 6 pass through the rope inlet holes and wrap around the generator flywheel 10. An energy storage device is mounted outside the housing 1, and the generator end of the generator 9 is connected to the energy storage device via a conductor. The cable is connected to the box 1, which has a rope outlet hole at the bottom. An external plate 14 is installed on the side of the box 1 near the support 2. A pulley groove 11 is provided on the external plate 14, and a third pulley 12 is installed in the pulley groove 11. The rope 6 passes through the rope outlet hole and is wrapped around the third pulley 12. A placement rack is installed on the same side of the box 1, and a barbell bar 13 is placed on the placement rack. The end of the rope 6 is tied to the barbell bar 13. When performing resistance training, the user pulls the barbell bar 13 to drive the barbell plate 3 to move longitudinally back and forth, causing the rope 6 wrapped around the generator flywheel 10 to move back and forth, thereby driving the generator flywheel 10 to rotate, which in turn causes the generator 9 to generate electricity. The generated electricity can be stored in the storage box, and it can also be used to charge personal electrical appliances through the charging unit, thereby converting mechanical energy into electrical energy and reducing energy loss.

[0040] The housing 1 is equipped with an oil injection assembly 15, and the first pulley 7 provides the rotational driving force for the oil injection assembly 15.

[0041] like Figures 1-6 and Figures 8-9As shown, the oil injection assembly 15 includes an oil injection housing 1501, an oil injection chamber 1502, a piston 1503, an oil reservoir 1504, an oil inlet pipe 1505, an oil injection pipe 1506, a slide 1507, a slider 1508, a connecting rod 1509, a connecting pipe 1510, a brush tube 1511, a first belt 1518, a support frame 1519, a center rod 1520, a cam 1521, an outer frame 1522, and a moving rod 1523. An external rod 1517 is installed at the center of one side of the first pulley 7. Two support frames 1519 are installed on the housing 1. A first pulley 1528 is installed on the external rod 1517. Two support frames 1519 are installed on the housing 1. A center rod 1520 is rotatably installed on the two support frames 1519. The support frame 1519 is connected via a central rod 1520. A second pulley 1529 is mounted on the central rod 1520. The first pulley 1528 and the second pulley 1529 are connected via a first belt 1518. A cam 1521 is mounted on the central rod 1520. An oil filling housing 1501 is mounted on the housing 1. The oil filling housing 1501 has symmetrical through holes at both ends. A rope 6 passes through the two through holes and enters the oil filling housing 1501. An oil filling chamber 1502 is provided inside the oil filling housing 1501. An oil storage tank 1504 is installed outside the oil filling housing 1501. The oil filling chamber 1502 and the oil storage tank 1504 are connected via an oil inlet pipe 1505. A piston 1503 is slidably mounted inside the oil filling chamber 1502. A moving rod 1523 is mounted on the piston 1503. The oil filling chamber 1502 has a connecting hole through which the moving rod 1523 passes, and an outer frame 1522 is installed at its end. The cam 1521 is located inside the outer frame 1522, and the outer contour of the cam 1521 contacts the inner side of the outer frame 1522. By utilizing the distance difference during the rotation of the cam, the outer frame can be moved accordingly. The top of the oil filling housing 1501 has a sliding groove 1507, and a slider 1508 is slidably installed in the sliding groove 1507. A connecting rod 1509 is installed at the bottom of the slider 1508, and a connecting pipe 1510 is installed at the bottom of the connecting rod 1509. The connecting pipe 1510 is connected to the oil filling chamber 1502 through an oil filling pipe 1506. Brush tubes 1511 are installed at the bottom of both ends of the connecting pipe 1510, and a rope 6 passes through the brush tubes 1511. 511. During resistance training, the user pulls the rope 6, causing it to reciprocate. This reciprocates the rope, causing the first pulley 7 to rotate due to friction. The first pulley 7 then rotates the center rod 1520 via the outer rod 1517 and the first belt 1518. The center rod 1520 then rotates the cam 1521 and the rotating wheel 1524. The cam 1521 pushes the outer frame 1522 to reciprocate laterally, which in turn drives the piston 1503 to reciprocate via the moving rod 1523. When the piston 1503 reciprocates, due to the suction effect, lubricating oil enters the oil injection chamber 1502 from the oil inlet pipe 1505 and is discharged into the connecting pipe 1510 through the oil injection pipe 1506, thus injecting oil into the brush tube 1511.

[0042] The oil filling assembly 15 also includes a connecting post 1512, a movable block 1513, a movable groove 1514, an external rod 1517, a rotating wheel 1524, a circumferential plate 1525, a connecting plate 1526, and a second belt 1527. A rotating wheel 1524 is mounted on the end of the central rod 1520 away from the first belt 1518. A fixing pin is fixedly mounted on the rotating wheel 1524, and a circumferential plate 1525 is rotatably mounted on the fixing pin. A connecting pin is mounted on the end of the circumferential plate 1525 away from the rotating wheel 1524, and a connecting plate 1526 is rotatably mounted on the connecting pin. A movable groove 1514 is formed on the side of the oil filling housing 1501 near the connecting plate 1526. A movable block 1513 is installed in the movable groove 1514 and is connected to the connecting plate 1526. The side of the movable block 1513 away from the connecting plate 1526 is connected to the connecting pipe 1510 via the connecting post 1512. The bottom of the housing 1 of the rotating wheel 1524 is provided with a belt groove. The rotating wheel 1524 on the housing 1 is connected to the rotating wheel 1524 inside the housing 1 by a second belt 1527. The second belt 1527 passes through the belt groove. When resistance training is performed, the rotating wheel 1524 causes the moving block 1513 to move back and forth in the moving groove 1514 through the circumferential plate 1525 and the connecting plate 1526, which drives the brush tube 1511 to move back and forth, so that the brush tube 1511 can fully contact the rope 6, thereby applying lubricating oil to the rope 6, reducing the friction between the rope 6 and the pulley system, so that the tension experienced by the user during resistance training is the preset weight of the barbell plate 3, reducing energy loss. Through the second belt 1527, the rotating wheel 1524 inside the housing 1 rotates, thereby causing the piston 1503 and the brush tube 1511 inside the housing 1 to move, thereby achieving synchronous oil injection.

[0043] The oil injection assembly 15 also includes an oil suction pipe 1515 and an oil return pipe 1516. The bottom of the brush tube 1511 is connected to the end of the oil injection chamber 1502 away from the oil injection pipe 1506 through the oil suction pipe 1515. The end of the oil injection chamber 1502 away from the oil inlet pipe 1505 is connected to the oil storage tank 1504 through the oil return pipe 1516. When oil injection is performed, excess lubricating oil is deposited at the bottom of the brush tube 1511. When the piston 1503 moves back and forth, due to the suction effect, excess lubricating oil flows back to the oil injection chamber 1502 through the oil suction pipe 1515 and returns to the oil storage tank 1504 through the oil return pipe 1516, realizing the recycling and reuse of excess lubricating oil. The oil inlet pipe 1505, the oil injection pipe 1506, the oil suction pipe 1515, and the oil return pipe 1516 are all unidirectional pipes.

[0044] The first pulley 7 is a ratchet, and the housing 1 and the oil filling housing 1501 are equipped with a self-locking component 16.

[0045] like Figure 2 , Figures 4-5 , Figure 7 , Figure 9 and Figure 11 As shown, the self-locking assembly 16 includes a through groove 1601, a fixed shaft 1602, a pawl 1603, and an electric telescopic rod 1604. An adjuster is installed inside the barbell plates 3. The electric telescopic rod 1604 is symmetrically installed on the top of the housing 1. The through groove 1601 is symmetrically opened at one end of the housing 1 near the first pulley 7. The fixed shaft 1602 is installed inside the through groove 1601. The pawl 1603 is rotatably installed on the fixed shaft 1602. One end of the pawl 1603 is engaged with the first pulley 7, and the other end is located on the center line of the electric telescopic rod 1604. The electric telescopic rod 1604 is electrically connected to the adjuster. When adjusting the weight, the adjuster detects the change in the number of barbell plates 3 and controls the extension of the electric telescopic rod 1604 so that the telescopic end of the electric telescopic rod 1604 abuts against one end of the pawl 1603, so that the other end of the pawl 1603 is fully engaged and locked with the first pulley 7, achieving a preliminary self-locking effect.

[0046] The self-locking assembly 16 also includes an electric push-pull rod 1605, a connector 1606, an outer ring 1607, an outer groove 1608, a coupling 1609, a retaining plate 1610, an inner ring 1611, and an inner groove 1612. An inner ring 1611 is symmetrically fixedly installed on the outside of the oil filling housing 1501. The inner ring 1611 is concentric with the through hole on the oil filling housing 1501. Multiple inner grooves 1612 are evenly distributed on the inner ring 1611. A coupling 1609 is slidably installed within the inner groove 1612. Multiple retaining plates 1610 are slidably installed on the inner ring 1611. An electric push-pull rod 1605 is symmetrically installed on the side of the oil filling housing 1501 near the inner ring 1611. A connector 1606 is rotatably installed on the telescopic end of the electric push-pull rod 1605. An outer ring 1607 is rotatably mounted on the connecting body 1606. Multiple outer grooves 1608 are evenly distributed on the outer ring 1607. Connecting holes are provided on the clamping plate 1610. Multiple connecting shafts 1609 pass through the connecting holes and are slidably installed within the outer grooves 1608. An electric push-pull rod 1605 is electrically connected to the adjuster. When adjusting the weight, the adjuster detects a change in the number of barbell plates 3 and controls the electric push-pull rod 1605 to retract, causing the outer ring 1607 to rotate. The outer ring 1607, through the connecting shafts 1609, drives the clamping plate 1610 to move, thereby causing the clamping plate 1610 to compress the rope 6, increasing the friction on the rope 6 and achieving a further self-locking effect. This prevents accidental rope pulling during weight adjustment, thus avoiding safety hazards.

[0047] like Figures 1-2 , Figures 4-5 and Figures 9-10As shown, clamps are symmetrically installed on the outside of the pulley groove 11. Rotating pins are installed on both clamps, and oil-absorbing sleeves are installed at the ends of the rotating pins. Rope 6 passes through the oil-absorbing sleeves. An oil reservoir is installed on the barbell plate 3, and an oil-absorbing sleeve is also installed on the barbell plate 3. Rope 6 passes through the oil-absorbing sleeve and the oil reservoir. A storage slot is installed outside the housing 1. A buffer pad is installed between the barbell plate 3 and the support 2. During resistance training, rope 6, installed inside the oil reservoir, prevents excess lubricating oil from dripping onto the barbell plate 3 during retraction. Rope 6, passing through the oil-absorbing sleeve, prevents excess lubricating oil from dripping onto the outer plate 14 during stretching, thus protecting the components. When training ends, the buffer pad effectively reduces the impact of the barbell plate 3 on the support 2, achieving the same protective effect.

[0048] Working principle of the present invention:

[0049] During resistance training, the user pulls the barbell bar, causing the barbell plates to move longitudinally back and forth. This causes the ropes wrapped around the generator flywheel to move back and forth, which in turn drives the generator flywheel to rotate, thus generating electricity. The generated electricity can be stored in a storage tank or used to charge personal electronic devices through a charging unit. This process converts mechanical energy into electrical energy, reducing energy loss.

[0050] During resistance training, the user pulls the rope, causing it to reciprocate. This reciprocating motion, through friction, drives the first pulley to rotate. The first pulley, via the outer rod and the first belt, drives the central rod to rotate. The central rod, in turn, drives the cam and the rotating wheel to rotate. The cam, by pushing the outer frame, reciprocates laterally. This, in turn, drives the piston to reciprocate via the moving rod. As the piston reciprocates, due to the suction effect, lubricating oil enters the oil injection chamber from the oil inlet pipe and is discharged into the connecting pipe through the oil injection pipe, thus injecting oil into the brush tube.

[0051] During resistance training, the rotating wheel moves the moving block back and forth in the moving groove through the circumferential plate and connecting plate, which in turn drives the brush tube to move back and forth, ensuring that the brush tube makes full contact with the rope. This allows for the application of lubricating oil to the rope, reducing friction between the rope and the pulley system. During resistance training, the user experiences a tension equal to the weight of the preset barbell plates, reducing energy loss. The second belt rotates the rotating wheel inside the box, which in turn moves the piston and brush tube inside the box, thus achieving synchronous oil injection.

[0052] When oil is injected, excess lubricating oil settles at the bottom of the brush tube. When the piston reciprocates, due to the suction effect, the excess lubricating oil flows back to the oil injection chamber through the oil suction pipe and returns to the oil storage tank through the oil return pipe, thus realizing the recycling and reuse of excess lubricating oil.

[0053] When adjusting the weight, the adjuster detects the change in the number of barbell plates and controls the electric push-pull rod to retract, causing the outer ring to rotate. The outer ring, through a connecting shaft, drives the locking plate to move, thereby squeezing the rope and increasing the friction on the rope. This achieves a further self-locking effect, preventing accidental rope pulling and potential safety hazards when adjusting the weight.

[0054] During resistance training, the rope is installed inside the oil reservoir to prevent excess lubricant from dripping onto the barbell plates during retraction. The rope also passes through an oil-absorbing sleeve to prevent excess lubricant from dripping onto the outer plate during stretching, thus protecting the components. When the training ends, the cushioning pad effectively reduces the impact of the barbell plates on the support, achieving the same protective function.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
