Description

Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, specifically to a vibration output structure. Furthermore, this invention also relates to a massage device incorporating this vibration output structure. Background Technology

[0002] Most fascia guns on the market currently use a motor-driven crank, which, through a connecting rod and slide mechanism hinged to the crank, converts the motor's rotational motion into the reciprocating linear motion of the slide, thus achieving the tapping output. For a given model, the amplitude is usually determined by the crank's eccentricity, and this eccentricity is fixed after the structural design is completed. This results in the amplitude being non-adjustable or having insufficient adjustment capability, making it difficult to meet the differentiated needs of different consumers in terms of massage intensity, applicable areas, and usage scenarios. Summary of the Invention

[0003] This invention provides a vibration output structure and a massage device thereof to solve the above-mentioned technical problems.

[0004] In a first aspect, the present invention provides a vibration output machine structure, including a mounting frame, an output mechanism, a bridging rod, an adjusting structure, and a crank-connecting rod structure. The output mechanism moves along a first axis, the axis of the bridging rod is set at an angle to the first axis, and the first end of the bridging rod is rotatably connected to the mounting frame, and the second end is connected to the adjusting structure. The adjusting structure is suitable for adjusting the rotation of the bridging rod around the first end. A slide block is slidably connected to the bridging rod, and an output connecting rod is hinged to the slide block. The output connecting rod is hinged to the output mechanism. The crank-connecting rod structure includes a crank and a driving connecting rod. The crank is rotatably connected to the mounting frame, and the driving connecting rod is hinged to both the crank and the slide block. The crank is connected to the output end of a power source mounted on the mounting frame.

[0005] Beneficial effects:

[0006] By changing the tilt angle of the bridging rod, the reciprocating movement distance of the slide block on the bridging rod can be changed, thereby changing the maximum reciprocating stroke of the sliding rod within the sliding sleeve, thus achieving the adjustment of the output amplitude of the vibration output structure.

[0007] Optionally, the adjustment structure includes a slide rail, which is constructed to extend in an arc around the first end of the bridging rod. The slide rail is connected to the mounting bracket, and the second end of the bridging rod is slidably connected to the slide rail via a slider.

[0008] Beneficial effects: This causes the center of the slide rail to coincide with the hinge point of the bridging rod, thereby forming an arc guide rail with the hinge point as the center in the rotation plane of the bridging rod.

[0009] Optionally, the adjustment structure also includes a drive element, and the vibration output structure also includes a controller. The drive element is connected to the mounting bracket, and is driven by the slider, and can drive the slider to slide along the extension direction of the slide rail. The controller is electrically connected to the drive element, and the controller controls the slider to slide along the slide rail through the drive element.

[0010] Beneficial effects: The slider can be moved on the slide rail by controlling the drive component, thereby adjusting the tilt angle of the bridging rod, which in turn changes the reciprocating stroke of the sliding rod and thus changes the vibration output amplitude.

[0011] Optionally, the driving component includes an adjusting motor and an adjusting wheel. The adjusting motor is mounted on a mounting bracket, and the controller is electrically connected to the adjusting motor. The adjusting wheel is driven by the adjusting motor, and its outer peripheral surface is at least partially constructed with a toothed structure. An arc-shaped rack extending in an arc around the first end of the bridging rod is formed on the slider, and the toothed structure of the adjusting wheel meshes with the arc-shaped rack.

[0012] Beneficial effects: When the driving force is stopped, the gear meshing structure locks the slider, thus keeping the bridging rod stably at the set tilt angle. Therefore, by controlling the opening, closing, and rotation direction of the driving component, the present invention can achieve precise movement of the slider on the slide rail, thereby enabling precise adjustment of the tilt angle of the bridging rod, which in turn changes the reciprocating stroke of the sliding rod and thus changes the vibration output amplitude.

[0013] Optionally, the mounting bracket includes a sliding groove configured to extend in an arc around a first end of the bridging rod, and a slider configured to extend in an arc around the first end of the bridging rod, adapting to the sliding groove and slidably connected to the sliding groove.

[0014] Beneficial effects: Therefore, the present invention can stabilize the sliding stroke of the slider through the sliding groove.

[0015] Optionally, the opening of the sliding groove is provided with a cover plate, which together with the sliding groove forms a sliding space. A strip-shaped hole is formed through the cover plate, which extends in an arc around the first end of the bridging rod. A drive rod is provided on the slider, which extends out of the strip-shaped hole along the depth direction of the sliding groove and can slide along the strip-shaped hole. The second end of the bridging rod is connected to the drive rod.

[0016] Beneficial effects: Further enhance the stability of the slider's sliding and limit the slider's sliding range.

[0017] Optionally, along the depth direction of the sliding groove, the slider has a portion protruding from the groove opening, a cover plate covers the slider, and the drive component is rotatably connected to the portion of the slider protruding from the groove opening.

[0018] Beneficial effects: To achieve the transmission connection between the slider and the driving component.

[0019] Therefore, the present invention can utilize the two ends of the strip hole to form a limiting structure, thereby limiting the rotation angle of the bridging rod.

[0020] Optionally, a first rolling shaft is formed on the surface of the cover plate facing the slider. The axial direction of the first rolling shaft is perpendicular to the sliding direction of the slider, and it is rotatably connected to the cover plate. The outer peripheral surface of the first rolling shaft abuts against the slider.

[0021] Beneficial effects: Therefore, the sliding resistance of the slider is reduced by the first rolling axis.

[0022] Optionally, a rolling element is rotatably provided on the inner wall of the sliding groove, and the two inner walls of the sliding groove are spaced apart from the corresponding sides of the slider. The rolling element has a rolling ring surface, which abuts against the corresponding sides of the slider.

[0023] Beneficial effects: Therefore, the sliding resistance between the slider and the sliding groove is reduced by the rolling annular surface of the rolling element.

[0024] Secondly, this application also includes a massage device, including a housing, a massage ball, and a vibration output structure as described above. The vibration output structure is disposed inside the housing and installed on the housing. The output mechanism includes a sliding sleeve and a sliding rod. The sliding sleeve is connected to the housing, and the sliding rod is slidably connected inside the sliding sleeve. The axial direction of the sliding rod forms a first axis. The sliding rod is hinged to the output connecting rod and connected to the massage ball located outside the housing.

[0025] Beneficial effects: This includes all the technical effects of the vibration output structure described above. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] refer to Figures 1 to 3This embodiment provides a vibration output structure, including a mounting frame 100, an output mechanism 600, an adjustment structure, a bridging rod 200, and a crank-connecting rod structure 500. The output mechanism 600 is configured to move along a first axis. The axis of the bridging rod 200 is angled to the first axis, and one end (first end 210) of the bridging rod 200 is hinged to the mounting frame 100, thus forming a pivot point relative to the mounting frame 100. The other end (second end 220) of the bridging rod 200 is connected to the adjustment structure 300. The adjustment structure 300 is used to adjust the rotation of the bridging rod 200 around its first end 210, thereby changing the angle between the bridging rod 200 and the first axis to alter the distribution of motion components during subsequent transmission.

[0031] A slide block 230 is fitted onto the bridging rod 200, and the slide block 230 is slidable along the axial direction of the bridging rod 200. A power source 400 (e.g., a drive motor) is mounted on the mounting bracket 100 and is spaced apart from the bridging rod 200 in the first axial direction (hereinafter referred to as the first direction). The power source 400 is hinged to the slide block 230 via a crank-connecting rod structure 500.

[0032] Specifically, the crank-connecting rod structure 500 includes a crank 510 (e.g., an eccentric wheel or other suitable structure) and a drive connecting rod 520. The crank 510 is connected to the output end of the power source 400 and is rotatably mounted relative to the mounting bracket 100. One end of the drive connecting rod 520 is hinged to the crank 510, and the other end is hinged to the slide block 230, thereby converting the rotational motion of the power source 400 into the reciprocating sliding of the slide block 230 along the axial direction of the bridging rod 200.

[0033] Therefore, when the power source 400 transmits motion to the slide 230 via the crank-connecting rod structure 500, its motion component in the axial direction of the bridging rod 200 changes with the tilt angle of the bridging rod 200, thereby changing the axial sliding stroke of the slide 230 on the bridging rod 200. Based on this, the operator can adjust the tilt angle of the bridging rod 200 to change the reciprocating distance of the slide 230 on the bridging rod 200, thus changing the maximum reciprocating stroke of the output mechanism 600 along the first axis, thereby adjusting the amplitude of the vibration output structure.

[0034] In this embodiment, the crank-connecting rod structure 500 can be disposed along the first axis on the side of the bridging rod 200 away from the output mechanism 600.

[0035] In one embodiment, the adjustment structure 300 may include a slide rail 310 configured to extend in an arc around the first end 210 of the bridging rod 200, such that the center of the slide rail 310 coincides with the hinge point of the bridging rod 200, thereby forming an arcuate guide track centered on the hinge point in the rotation plane of the bridging rod 200.

[0036] The slide rail 310 is connected to the mounting bracket 100. The second end 220 of the bridging rod 200 is slidably connected to the slide rail 310 via a slider 320, allowing the slider 320 to move in an arc around the hinge point of the first end 210 of the bridging rod 200. The first end 210 of the bridging rod 200 can be hinged or fixedly connected to the slider 320. Therefore, as the slider 320 slides along the slide rail 310, it can drive the bridging rod 200 to rotate synchronously, thus adjusting the tilt angle of the bridging rod 200.

[0037] Furthermore, the mounting bracket 100 includes a sliding groove 311, which is configured to extend in an arc around the first end 210 of the bridging rod 200. The slider 320 is configured to extend in an arc around the first end 210 of the bridging rod 200, and is adapted to the sliding groove 311 and slidably connected to the sliding groove 311 to improve the guiding accuracy and stability of the slider 320 during movement, thereby forming the above-mentioned slide rail 310 structure.

[0038] Specifically, refer to Figure 7 The sliding groove 311 may include a first arc-shaped side plate, a second arc-shaped side plate, and an arc-shaped bottom plate. The first arc-shaped side plate and the second arc-shaped side plate are disposed on both sides of the arc-shaped bottom plate along a first direction, and the three together form a sliding groove 311 space for sliding of the slider 320.

[0039] In one embodiment, the adjustment structure 300 further includes a drive element 330, and the vibration output structure further includes a controller. The drive element 330 is connected to the mounting bracket 100, and the drive element 330 is pulsatorically connected to the slider 320 and can drive the slider 320 to slide along the extension direction of the slide rail 310.

[0040] Specifically, combined Figure 6 The driving end of the driving member 330 is connected to the slider 320 through any suitable form of transmission, such as a toothed meshing structure, to apply a driving force to the slider 320 along the direction of the slide rail 310. When the driving member 330 stops outputting driving force, the toothed meshing structure can also lock the slider 320, thereby allowing the bridging rod 200 to be stably maintained at the set tilt angle position.

[0041] The vibration output structure also includes a controller, which is electrically connected to the drive component 330. The controller controls the slider 320 to slide along the slide rail 310 via the drive component 330. Therefore, in this embodiment, the controller can control the opening, closing, and rotation direction of the drive component 330, enabling precise movement of the slider 320 on the slide rail 310. This allows for adjustment of the tilt angle of the bridging rod 200, thereby changing the reciprocating stroke of the sliding rod 620 and thus altering the vibration output amplitude.

[0042] In one embodiment, the drive unit 330 includes an adjusting motor 332 and an adjusting wheel 331. The adjusting motor 332 is mounted on the mounting bracket 100. The controller is electrically connected to the adjusting motor 332. The adjusting wheel 331 is connected to the adjusting motor 332 through any suitable structure. The outer peripheral surface of the adjusting wheel 331 is at least partially constructed as a toothed structure.

[0043] The slider 320 has an arc-shaped rack 323 extending in an arc around the first end 210 of the bridging rod 200. The toothed structure of the adjusting wheel 331 meshes with the arc-shaped rack 323, thereby locking the slider 320 through the toothed structure, thus allowing the bridging rod 200 to be stably maintained at a set tilt angle position. The adjusting wheel 331 can be a complete gear. It should be noted that if a partial toothed structure is used, it needs to be set according to the adjustment range of the bridging rod 200, i.e., the sliding range of the slider 320.

[0044] In one embodiment, a cover plate 700 is provided at the opening of the sliding groove 311. The cover plate 700 and the sliding groove 311 together form a sliding space, thereby constraining the slider 320 circumferentially together with the first arc-shaped side plate, the second arc-shaped side plate, the arc-shaped bottom plate and the cover plate 700 in the sliding groove 311. This prevents the slider 320 from applying traction force to the hinge point of the bridging rod 200 during sliding, which could cause the hinge point of the bridging rod 200 to loosen, resulting in the slider 320 tilting or derailing.

[0045] The cover plate 700 can be installed at the top slot 312 of the sliding groove 311 via a connecting structure, for example, by connecting and fixing it to the mounting post with screws.

[0046] Further, refer to Figure 1 and Figure 5The bridging rod 200 can be connected to the slider 320 via the drive rod 321. A strip-shaped hole 710 is provided on the cover plate 700 for the drive rod 321 to pass through. This strip-shaped hole 710 penetrates the cover plate 700 and is arc-shaped. Similarly, the center of the strip-shaped hole 710 is set to coincide with the hinge point of the first end 210 of the bridging rod 200, so that the drive rod 321 located within the strip-shaped hole 710 moves along an arc path around the hinge point, following the bridging rod 200 within the strip-shaped hole 710. Based on this, this embodiment can apply a stopping effect to the drive rod 321 at both ends of the strip-shaped hole 710, which can limit the maximum and minimum rotation angle of the bridging rod 200, thereby limiting the amplitude adjustment range and improving structural safety and reliability.

[0047] The cover plate 700 has a through-hole 710. The through-hole 710 extends in an arc around the first end 210 of the bridging rod 200. The slider 320 is provided with a driving rod 321. The driving rod 321 extends out of the through-hole 710 along the groove depth direction of the sliding groove 311 and can slide along the through-hole 710. The second end 220 of the bridging rod 200 is connected to the driving rod 321. Thus, the two ends of the through-hole 710 can restrict the position of the driving rod 321 within it, thereby avoiding over-adjustment of the bridging rod 200.

[0048] In one embodiment, along the depth direction of the sliding groove 311, the slider 320 has a portion protruding from the groove opening, the cover plate 700 covers the slider 320, and the drive member 330 is rotatably connected to the portion of the slider 320 protruding from the groove opening.

[0049] Specifically, refer to Figure 6 The slider 320 has a partially protruding top slot 312 of the sliding groove 311. Both the drive member 330 and the bridging rod 200 can be connected to the protruding portion of the slider 320. An arc-shaped rack 323 is formed on this protruding portion.

[0050] Specifically, refer to Figure 6 The arc-shaped rack 323 is installed on the part of the slider 320 that protrudes from the sliding groove 311 and is located on the slider 320 facing the power source 400. The aforementioned drive member 330 can be disposed on the side of the adjustment structure 300 facing the power source 400 and is located between the adjustment structure 300 and the power source 400.

[0051] In this embodiment, combined with Figure 5 and Figure 7 The cover plate 700 can also be arc-shaped to match the shape of the top slot 312 of the sliding groove 311.

[0052] To reduce the sliding resistance of the slider 320 and improve the adjustment response speed, in one embodiment, a first rolling shaft 324 is formed on the surface of the cover plate 700 facing the slider 320. The outer peripheral surface of the first rolling shaft 324 abuts against the cover plate 700 on the side away from the slider 320, so that the first rolling shaft 324 is partially located between the slider 320 and the cover plate 700. Thus, when the slider 320 moves relative to the sliding groove 311, rolling friction replaces sliding friction, significantly reducing resistance.

[0053] Among them, reference Figure 5 and Figure 6 The surface of the slider 320 facing the cover plate 700 can be spaced apart from the cover plate 700.

[0054] The first rolling shaft 324 is configured such that its axial direction is perpendicular to the sliding direction of the slider 320. That is, the axial direction of the first rolling shaft 324 lies within the rotation plane of the bridging rod 200, and this axial direction points towards the hinge point of the second end 220 of the bridging rod 200. This axial direction can also be understood as the radial direction pointing towards the center of the arc-shaped structure, such as the sliding groove 311. Based on this, in this embodiment, the first rolling shaft 324 can eliminate the sliding friction between the slider 320 and the cover plate 700 by rolling when the slider 320 slides relative to the sliding groove 311, thereby reducing the sliding resistance of the slider 320.

[0055] In one embodiment, reference Figure 6 The slider 320 can be constructed as an arc-shaped strip plate 322, the arc length of which is greater than the arc length of the sliding groove 311. The two ends of the sliding groove 311 form an open structure to allow the ends of the strip plate 322 to pass through. The two sides of the strip plate 322 are limited and guided by rolling elements with respect to the inner wall of the sliding groove 311. Compared with a surface contact structure, this can effectively reduce the contact area and improve the smoothness of sliding.

[0056] In one embodiment, a rolling element is rotatably provided on the inner wall of the sliding groove 311, and the two inner walls of the sliding groove 311 are spaced apart from the corresponding sides of the slider 320. The rolling element has a rolling ring surface, which abuts against the corresponding side of the slider 320 to further reduce the frictional resistance of the slider 320.

[0057] Specifically, refer to Figure 6 and Figure 7Along the radial direction of the sliding groove 311, the two sides of the strip plate 322 (facing the bridging rod 200 and away from the bridging rod 200) are spaced apart from the two inner sidewalls of the sliding groove 311. At least one of the rolling elements is provided on both sides of the slide rail 310. The rolling element has a portion located between the inner sidewalls of the strip plate 322 and the sliding groove 311, and the end of this portion facing the strip plate 322 is constructed as an arc and abuts against the corresponding side of the strip plate 322 to constrain both sides of the strip plate 322. At the same time, compared with the surface contact between the strip plate 322 and the sidewalls of the sliding groove 311, the contact area can be reduced, thereby reducing the sliding resistance of the strip plate 322.

[0058] In one embodiment, reference Figure 4 , Figure 7 and Figure 8 The aforementioned rolling element includes a connecting rod 325, which connects to the opening of the sliding groove 311. For example, four rolling elements are provided at the opening of the sliding groove 311, and these four rolling elements are equally and symmetrically distributed at the opening of the sliding groove 311, thus being located on the outer and inner sides of the strip block. The connecting rod 325 can extend in a direction away from the sliding groove 311, that is, in a direction perpendicular to the end face of the opening of the sliding groove 311.

[0059] As can be understood, as mentioned above, the outer and inner sides refer to the two sides facing away from and towards the power source 400, respectively. A bearing 326 can be fitted onto the connecting rod 325. The outer ring of the bearing 326 abuts against the portion of the strip plate 322 that protrudes from the sliding groove 311, thereby constraining the corresponding sides of the strip plate 322. The outer ring of the bearing 326 rotates relative to the inner ring to further reduce the sliding resistance of the strip plate 322.

[0060] The aforementioned cover plate 700 can be connected to the end of the connecting rod 325 facing the cover plate 700 by bolts and threads.

[0061] In one embodiment, a fixing seat 327 may be provided at the top slot 312 of the sliding groove 311. For example... Figure 7 and Figure 8 In the illustrated embodiment, the fixing base 327 can be a circular platform disposed at the opening of the sliding groove 311, for example, on the opposite sides of the first and second arc-shaped side plates. Of course, the fixing base 327 can also be other adaptable structures.

[0062] The connecting rod 325 can be correspondingly connected to the fixed seat 327. The connecting rod 325 can pass through the fixed seat 327 along the depth direction of the sliding groove 311, thereby being divided into upper and lower parts by the fixed seat 327, and spaced apart from the corresponding first arc-shaped side plate and second arc-shaped side plate; or, each fixed seat 327 is provided with a connecting rod 325 on both the upper and lower end faces along the depth direction of the sliding groove 311, so as to form mounting positions for mounting the bearing 326 in the upper and lower parts of the fixed seat 327. Reference Figure 7 and Figure 8 The first and second arc-shaped side plates are provided with arc-shaped grooves at the positions corresponding to the fixed seat 327. The lower part of the connecting rod 325 can be located in the groove, and the bearing 326 located in the groove is also located in the groove.

[0063] In this design, the connecting rod 325 is fitted with bearings 326 on both the upper and lower parts of the fixed base 327. The upper bearing 326 abuts against the protruding part of the slider 320. The lower bearing 326 can partially pass through the openings 313 on both sides of the sliding groove 311 and abut against one side of the strip plate 322. The openings 313 can be correspondingly opened on the groove surface near the sliding groove 311 of the aforementioned arc-shaped groove, allowing the bearing 326 to pass through the openings 313 and abut against the corresponding side of the strip plate 322. Thus, through the upper and lower bearings 326, two constraints can be applied to the slider 320 at one location on the fixed base 327, thereby improving the stability of the slider 320's movement. Thus, the connecting rod 325 and the bearings 326 constitute the aforementioned rolling element. Therefore, the outer peripheral surface of the bearing 326 constitutes the rolling annular surface.

[0064] The mounting bracket 100 in this embodiment may include a motor bracket 110, an adjustment bracket 120, and a slide rail bracket 130. The motor bracket 110, the adjustment bracket 120, and the slide rail bracket 130 are connected sequentially along a first direction. The power source 400 is installed on the motor bracket 110, the drive component 330 is installed on the adjustment bracket, and the slide rail 310 can be installed on the slide rail bracket 130.

[0065] The slide rail 310 can be integrally formed with the slide rail bracket 130, that is, its second arc-shaped side plate is connected to the adjustment bracket 120, thereby fixing the slide rail 310.

[0066] The mounting bracket 100 can be a one-piece molded part.

[0067] Secondly, this embodiment also includes a massage device, including a housing, a massage ball, and a vibration output structure as described above. The vibration output structure is disposed inside the housing and installed to the housing. The output mechanism 600 includes a sliding sleeve 610 and a sliding rod 620. The sliding sleeve 610 is connected to the housing, and the sliding rod 620 is slidably connected inside the sliding sleeve 610. The axial direction of the sliding rod 620 forms the first axis. The sliding rod 620 is hinged to the output connecting rod 800 and connected to the massage ball located outside the housing.

[0068] Therefore, in this embodiment, the sliding sleeve 610 is indirectly mounted on the mounting bracket 100, and it can be located on the side of the slide block 230 away from the power source 400. That is, the sliding sleeve 610, the slide block 230, and the power source 400 are arranged sequentially at intervals along the first direction. A sliding rod 620 is slidably disposed inside the sliding sleeve 610 along its axial direction. One end of the sliding rod 620 facing the slide block 230 is connected to an output connecting rod 800 by a hinge, and the other end of the output connecting rod 800 is hinged to the slide block 230. Thus, when the slide block 230 reciprocates on the bridging rod 200, the reciprocating motion can be transmitted to the sliding rod 620 through the output connecting rod 800, thereby driving the sliding rod 620 to perform linear reciprocating motion in the axial direction within the sliding sleeve 610, so that the sliding rod 620 constitutes the vibration output end of the vibration output structure.

[0069] Therefore, the reciprocating stroke of the slide block 230 on the bridging rod 200 directly determines the maximum reciprocating stroke of the output connecting rod 800 and the sliding rod 620 within the sliding sleeve 610. Specifically, when the slide block 230 reaches its upper and lower dead points on the bridging rod 200, the sliding rod 620 also reaches its maximum stroke dead point in the direction towards the bridging rod 200, thus forming the corresponding vibration output amplitude.

[0070] Therefore, with parameters and rotation speed remaining constant, this embodiment can change the reciprocating movement distance of the slide block 230 on the bridge rod 200 by changing the tilt angle of the bridge rod 200, thereby changing the maximum reciprocating stroke of the sliding rod 620 within the sliding sleeve 610, and thus adjusting the output amplitude of the vibration output structure.

[0071] Generally, reference Figure 3 and Figure 4 The bridging rod 200 and the crank-connecting rod structure 500 move in the same plane of motion. The fixed point where the crank 510 is connected to one of its drive members 330 is axially aligned with the sliding rod 620. The slide 230 may include a linear bearing 231 to allow sliding on the bridging rod 200. The drive shaft of the aforementioned drive motor connects to the crank 510 in the crank-connecting rod structure 500 (e.g., ...). Figure 8The crank 510 shown is connected to the slide 230 via the drive connecting rod 520, thereby converting the rotational motion of the power source 400 into the reciprocating linear motion of the slide 230 along the axial direction of the bridging rod 200.

[0072] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
