Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of silicon-based OLED display, and particularly relates to a lamp string type LED remote control variable solar energy traffic sign. BACKGROUND

[0002] Traffic signs play an important role in traffic management, not only improve traffic efficiency, but also provide safety for vehicle travel, and currently, traffic signs in China mainly include traditional traffic signs and LED traffic signs, wherein the LED traffic signs are divided into LED lighting traffic signs and full dot matrix type LED screen variable traffic signs.

[0003] The existing solar energy traffic signs are mostly circular or square, and the shapes thereof are fixed, when the road is maintained, the road maintenance personnel can only transport corresponding traffic signs to the site according to the actual situation, and the shape of the traffic sign cannot be freely changed according to the actual situation, so that the traffic sign cannot express different prompt information; and the lamp string type LED lamp on the current solar energy traffic sign is fixed on the traffic sign plate through a fixed screw, which is very inconvenient when it needs to be maintained and replaced; meanwhile, the shape of the existing solar energy traffic sign is single, and different traffic identification information cannot be provided according to the actual demand, so that the application range of the existing solar energy traffic sign is very limited. SUMMARY

[0004] The technical problem to be solved by the application is to overcome the shortcomings of the prior art, and to provide a lamp string type LED remote control variable solar energy traffic sign.

[0005] The technical scheme adopted to solve the above technical problem is that the lamp string type LED remote control variable solar energy traffic sign comprises a base box serving as an installation carrier, a support pipe is installed at the top of the base box, a connecting mechanism is arranged at the top end of the support pipe, a main body bin is arranged in the connecting mechanism, two end-symmetrical closing plates are installed at the two ends of the main body bin, a main LED lamp string mechanism is arranged on the inner side of the closing plate through a fixing mechanism, a connecting pipe is jointly installed at the center position between the two closing plates, two end-symmetrical driving mechanisms that are matched with the fixing mechanism are arranged in the main body bin, a second adjusting mechanism matched with the driving mechanism is arranged at one end in the main body bin, a first adjusting mechanism providing driving force for the driving mechanism is arranged on the outer side of the connecting pipe, and a protection mechanism matched with the second adjusting mechanism is arranged on the outer side of the connecting pipe.

[0006] A photovoltaic power generation module is installed at the top of the connecting mechanism, a storage battery is installed at the bottom end in the base box, a control panel is installed on one side in the base box, and power supply sockets matched with the main LED lamp string mechanism are installed at two end-symmetrical positions in the connecting pipe.

[0007] Further, the main LED light string mechanism comprises a lamp plate outside the closing plate, the outer side of the lamp plate is uniformly provided with a light emitting diode chip, and the outer side of the light emitting diode chip is provided with a transparent epoxy resin package, and the inner side of the lamp plate is provided with a power supply plug matched with the power supply socket.

[0008] Through the above technical scheme, the battery supplies power to the power supply socket through the wire, and after the power supply plug on the inner side of the lamp plate is inserted into the power supply socket, the lamp plate and the light emitting diode chip can be powered, the light emitting diode chip is controlled to be electrified and emits light, and the light emitted by the light emitting diode chip is diffused by the transparent epoxy resin package, so that the whole solar energy traffic sign can clearly prompt the corresponding information.

[0009] Further, the fixing mechanism comprises a trapezoidal clamping block inside the lamp plate, the trapezoidal clamping block is provided with four groups, and the four groups of trapezoidal clamping blocks are located at non-central positions inside the lamp plate, four groups of rotating plates are uniformly hinged at non-central positions inside the closing plate, four groups of return springs are uniformly installed inside the closing plate, one end of the return spring is fixedly connected with the outer side of an adjacent group of rotating plates, a clamping groove matched with the trapezoidal clamping block is formed at one end of the top of the rotating plate, a guide groove is formed at one end of the bottom of the rotating plate close to the clamping groove, four groups of insertion grooves matched with the trapezoidal clamping block are uniformly formed on the outer side of the closing plate, and four groups of limiting columns close to the insertion grooves are uniformly installed on the inner side of the closing plate.

[0010] Through the above technical scheme, when the inner side of the lamp plate is tightly attached to the outer side of the closing plate, the head end of the trapezoidal clamping block passes through the insertion groove and enters the main body cavity, in the process, the top end of the trapezoidal clamping block pushes the rotating plate along the guide of the guide groove to rotate a little around the hinged shaft connected with the closing plate, the return spring is shortened under stress, when the top end of the trapezoidal clamping block is higher than the clamping groove, the elastic potential energy of the return spring pushes the rotating plate to rotate back to the original position, at this time, the top end of the trapezoidal clamping block is clamped with the clamping groove, and then the lamp plate is stably fixed on the outer side of the closing plate, and then the first adjusting mechanism can be matched to release the clamping of the trapezoidal clamping block and the clamping groove, so that the lamp plate on the outer side of the closing plate can be easily disassembled.

[0011] Further, the first adjusting mechanism comprises a connecting bearing, the connecting bearing is provided with two groups, and the two groups of connecting bearings are respectively located at the top and the bottom of the connecting pipe outside, the outer side of the connecting bearing is installed with a rotating disc, and the edge position of the mutually far away one surface of the two groups of rotating discs is uniformly installed with four groups of poking columns.

[0012] Through the above technical scheme, when the driving mechanism drives the rotating disc to rotate, the four groups of movable plates can be freely adjusted to extend out or retract from the main body cavity, and the end of the rotating plate can be poked by the poking column to release the fixing effect of the fixing mechanism on the lamp plate.

[0013] Furthermore, the drive mechanism includes a rotating ring located at the inner ring of the top of a set of rotating disks, a driven rack mounted on the outer ring of the rotating ring, a fixed ring mounted at the middle position of the outer side of the connecting pipe, and a mounting bracket mounted on the top of the fixed ring. A servo motor is mounted on the inner top of the mounting bracket, and a drive gear that meshes with the driven rack is mounted on the output shaft of the servo motor.

[0014] The above technical solution controls the servo motor to drive the drive gear to rotate. The drive gear, in conjunction with the driven rack and rotating ring, drives a set of rotating disks to rotate. This set of rotating disks, in turn, drives another set of rotating disks to rotate synchronously through a connecting ring.

[0015] Furthermore, the second adjustment mechanism includes an arc-shaped through groove, and four sets of the arc-shaped through groove are provided. The four sets of arc-shaped through grooves are evenly distributed on the same end of the outer side of the main body compartment. A movable plate is hinged to one side of the inside of the arc-shaped through groove. A secondary LED light string mechanism is installed on the same side of the four sets of movable plates. A sliding column is installed on one side of the movable plate. Four sets of first arc-shaped holes that cooperate with the sliding columns are evenly opened at the bottom of one set of rotating disks. A second arc-shaped hole that communicates with the first arc-shaped hole is opened near the edge of the rotating disk.

[0016] Through the above technical solution, the adjusting mechanism, in conjunction with the sliding column, pushes the movable plate to rotate around the hinge shaft connected to the arc-shaped through slot. During the process, the sliding column slides inside the first arc-shaped hole along the guide of the first arc-shaped hole, allowing the movable plate to gradually pass through the arc-shaped through slot and be exposed on the outside of the main body compartment. This allows the four sets of movable plates to work with the main LED light string mechanism to form a square traffic sign. The second arc-shaped hole, in conjunction with the sliding column, ensures that when the rotating disk rotates counterclockwise again, it will not cause the movable plate to move. The actuating column on the rotating disk can work with the fixing mechanism to automatically release the fixing mechanism from the main LED light string mechanism.

[0017] Furthermore, the protection mechanism includes a connecting ring located outside the connecting pipe. The top and bottom of the connecting ring are fixedly connected to the edges of the two sets of rotating disks, respectively. Four sets of limiting through grooves are evenly opened on the inner side of the connecting ring. A lifting ring is sleeved on the outer side of the connecting pipe, and four sets of connecting rods are evenly installed on the outer ring of the lifting ring. The ends of the four sets of connecting rods away from the lifting ring pass through the limiting through grooves and extend to the outer side of the main body compartment, where a protective ring is installed. Four sets of lifting through holes that cooperate with the connecting rods are evenly opened on the outer side of the main body compartment.

[0018] With the above technical solution, when the rotating disk rotates, the connecting ring rotates along with it, and the connecting rod slides inside the limiting groove. During the process, the limiting groove, together with the connecting rod, drives the lifting ring and the protective ring to move synchronously. In this way, before the movable plate extends out of the main body compartment, the protective ring will no longer block the arc-shaped groove. And after the movable plate retracts into the main body compartment, the protective ring will automatically block the four sets of arc-shaped grooves on the outside of the main body compartment, preventing external dust or rainwater from entering the interior of the main body compartment through the arc-shaped groove.

[0019] Furthermore, the connecting mechanism includes a mounting ring located at the top of the support tube, an annular groove is provided on the inner side of the mounting ring, a sliding ring that cooperates with the annular groove is installed on the outer ring of the protective ring, two sets of fixed limiting blocks are installed on the outer side of the mounting ring, a movable limiting block that cooperates with the two sets of fixed limiting blocks is installed on the outer side of the protective ring, and a wing screw that cooperates with the protective ring is installed on the outer ring of the mounting ring.

[0020] Using the above technical solution, the main body is rotated 90° clockwise, causing the movable limiting block on the outside of the protective ring to move from one set of fixed limiting blocks to another set of fixed limiting blocks. During this process, the sliding ring slides inside the annular groove. Then, the wing screw is tightened to fix the protective ring and the mounting ring, thus fixing the position of the main body and preventing it from rotating. At this point, the traffic sign can be changed from a square to a rhombus.

[0021] Furthermore, four sets of fixing screw holes are evenly arranged on the inner wall of the main compartment near the two sets of sealing plates. Four sets of fixing screws that cooperate with the fixing screw holes are threaded on the outer edge of the two sets of sealing plates. Splicing blocks are symmetrically arranged at both ends of the connecting pipe. Splicing grooves that cooperate with the splicing blocks are symmetrically opened at the middle position of the inner side of the two sets of sealing plates.

[0022] With the above technical solution, after the main LED light string mechanism is removed from the outside of the enclosure, the four sets of fixing screws are unscrewed to release the fixed connection between the enclosure and the main body. Then the enclosure is removed. During the process, the splicing blocks and splicing grooves are separated, which helps the staff to inspect and maintain the components inside the main body.

[0023] Furthermore, a first through hole is provided at the top of the outer side of the support tube, a second through hole is provided on the outer side of the main body compartment, and a third and a fourth through hole are provided on the outer side of the connecting tube, respectively.

[0024] The above technical solution allows the battery and control panel to pass through the first through hole, the second through hole, and the third through hole in sequence with wires before entering the interior of the connecting pipe. A portion of the wires are electrically connected to the two sets of power supply sockets, and the remaining wires pass through the fourth through hole into the main body compartment and are then electrically connected to the servo motor and the auxiliary LED light string mechanism.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention drives the first adjustment mechanism through the drive mechanism, and the first adjustment mechanism adjusts the movable plate to extend from the inside of the main body through the arc-shaped through slot. At this time, a set of main LED light string mechanism and four sets of movable plates extending from the inside of the main body can form a complete square sign. With the auxiliary LED light string mechanism installed on the movable plate, the entire solar traffic sign not only has the reminder function of a round sign, but also the reminder function of a square traffic sign, which greatly improves the applicability of the entire solar traffic sign; (2) The present invention uses a fixing mechanism to stably install the main LED light string mechanism on the outside of the closed plate. When replacing the main LED light string mechanism, it is only necessary to control the drive mechanism to drive the first adjustment mechanism to rotate to the maximum rotation angle. During the process, the dial in the first adjustment mechanism is used to fix the main LED light string mechanism. The moving column will automatically release the fixing mechanism from the main LED light string mechanism, thus making it easier for staff to freely replace the main LED light string mechanism on the outside of the closed plate. In addition, with the second adjustment mechanism that can freely change the shape of the traffic sign, the entire solar traffic sign can display different traffic information and thus be applicable to different traffic scenarios. (3) The present invention can freely adjust the rotation angle of the main compartment by 90° through the connecting mechanism. With the second adjustment mechanism that can change the solar traffic sign from a circle to a square, the square solar traffic sign can be changed into a rhombus solar traffic sign. In addition, with the fixing mechanism that can freely replace the main LED light string mechanism, the solar traffic sign has the information prompt function of a rhombus sign, which further improves the applicability of the solar traffic sign.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0052] like Figures 1-23As shown, the string LED remote-controlled variable solar traffic sign of this embodiment includes a base box 1 as an installation carrier. A support tube 2 is installed on the top of the base box 1. A connecting mechanism 3 is provided at the top of the support tube 2, and a main body compartment 4 is provided inside the connecting mechanism 3. The connecting mechanism 3 includes an installation ring 301 located at the top of the support tube 2. An annular groove 302 is provided on the inner side of the installation ring 301. A sliding ring 303 that cooperates with the annular groove 302 is installed on the outer ring of the protective ring 115. Two sets of fixed limiting blocks 304 are installed on the outer side of the installation ring 301. A movable limiting block 305 that cooperates with the two sets of fixed limiting blocks 304 is installed on the outer side of the protective ring 115. The main body 4 is equipped with a wing screw 306 that cooperates with the protective ring 115. The main body 4 is manually rotated 90° clockwise, so that the movable limit block 305 on the outside of the protective ring 115 moves from one set of fixed limit blocks 304 to another set of fixed limit blocks 304. During this process, the sliding ring 303 slides inside the annular groove 302. Then, the wing screw 306 is tightened to fix the protective ring 115 to the mounting ring 301, thus fixing the position of the main body 4 so that it can no longer rotate. At this time, the traffic sign can be changed from square to diamond. At this time, in conjunction with the main LED light string mechanism 12 and the secondary LED light string mechanism 803, the entire traffic sign can play the role of indicating other information.

[0053] like Figures 1-7 and Figures 16-21As shown, in this embodiment, the main body compartment 4 has symmetrically installed sealing plates 5 at both ends. A main LED string mechanism 12 is installed on the inner side of the sealing plates 5 via a fixing mechanism 6. A connecting pipe 10 is installed at the center between the two sets of sealing plates 5. Power supply sockets 16 that cooperate with the main LED string mechanism 12 are symmetrically installed at both ends inside the connecting pipe 10. The fixing mechanism 6 includes trapezoidal blocks 604 located inside the lamp plate 121. Four sets of trapezoidal blocks 604 are provided, and the four sets of trapezoidal blocks 604 are located at non-central positions inside the lamp plate 121. Four sets of rotating plates 601 are evenly hinged at non-central locations. Four sets of return springs 602 are evenly installed on the inner side of the closed plate 5, and one end of the return spring 602 is fixedly connected to the outer side of the adjacent set of rotating plates 601. A slot 603 is provided at the top end of the rotating plate 601 to cooperate with the trapezoidal locking block 604. A guide groove 605 is provided at the bottom end of the rotating plate 601 near the slot 603. Four sets of slots 606 are evenly provided on the outer side of the closed plate 5 to match the trapezoidal locking block 604. Four sets of slots 606 are evenly installed on the inner side of the closed plate 5 near the slots 606. The limiting post 607 and the main LED light string mechanism 12 include a light plate 121 located outside the closed plate 5. Light-emitting diode chips 122 are evenly distributed on the outer side of the light plate 121, and transparent epoxy resin encapsulation 123 is provided on the outer side of the light-emitting diode chips 122. A power plug 124 that mates with the power supply socket 16 is installed at the center of the inner side of the light plate 121. When the inner side of the light plate 121 is pressed tightly against the outer side of the closed plate 5, the head end of the trapezoidal locking block 604 passes through the slot 606 and enters the main body compartment 4. During this process, the top end of the trapezoidal locking block 604 follows the guide... The guide of slot 605 pushes the rotating plate 601 to rotate slightly around the hinge shaft connected to the closed plate 5. The return spring 602 is shortened by force. When the top of the trapezoidal block 604 is higher than the slot 603, the elastic potential energy of the return spring 602 pushes the rotating plate 601 to rotate back to its original position. At this time, the top of the trapezoidal block 604 engages with the slot 603, thereby stably fixing the lamp board 121 on the outside of the closed plate 5. The control panel 15 can control the switching of the light-emitting diode chip 122 on the outside of the lamp board 121 through the power supply socket 16 and the power supply plug 124.

[0054] like Figures 7-15As shown, in this embodiment, drive mechanisms 9, which cooperate with fixing mechanisms 6, are symmetrically arranged at both ends inside the main body compartment 4. A second adjustment mechanism 8, which cooperates with drive mechanism 9, is arranged at one end inside the main body compartment 4. A first adjustment mechanism 7, which provides driving force to drive mechanism 9, is arranged on the outside of connecting pipe 10. The first adjustment mechanism 7 includes connecting bearings 701, and two sets of connecting bearings 701 are arranged, with the two sets of connecting bearings 701 located at the top and bottom of the outside of connecting pipe 10, respectively. A rotating disk 702 is installed on the outside of the connecting bearings 701. Four sets of actuating columns 703 are evenly installed at the edge positions of the two sets of rotating disks 702 that are far apart from each other. The drive mechanism 9 includes a drive mechanism 8 located at the top of one set of rotating disks 702. A rotating ring 901 is located at the ring position. A driven rack 902 is installed on the outer ring of the rotating ring 901. A fixed ring 903 is installed at the middle position of the outer side of the connecting pipe 10. A mounting bracket 904 is installed on the top of the fixed ring 903. A servo motor 905 is installed on the inner top of the mounting bracket 904. A drive gear 906 that meshes with the driven rack 902 is installed on the output shaft of the servo motor 905. The second adjustment mechanism 8 includes an arc-shaped through groove 801. Four sets of arc-shaped through grooves 801 are provided. The four sets of arc-shaped through grooves 801 are evenly distributed on the same end of the outer side of the main body compartment 4. A movable plate 802 is hinged to one side of the inside of the arc-shaped through groove 801. A secondary LED light string mechanism 80 is installed on the same side of each of the four sets of movable plates 802. 3. The secondary LED string mechanism 803 has the same structure as the main LED string mechanism 12. A sliding column 804 is installed on one side of the movable plate 802. Four sets of first arc-shaped holes 805 that cooperate with the sliding column 804 are evenly opened on the bottom of a set of rotating disks 702. A second arc-shaped hole 806 communicating with the first arc-shaped hole 805 is opened near the edge of the rotating disk 702. The servo motor 905 drives the drive gear 906 to rotate. The drive gear 906, in conjunction with the driven rack 902 and the rotating ring 901, drives a set of rotating disks 702 to rotate. This set of rotating disks 702, in turn, drives another set of rotating disks 702 to rotate synchronously through the connecting ring 111. The rotating disks 702 cooperate with the sliding column 804. The movable column 804 pushes the movable plate 802 to rotate around the hinge shaft connected to the arc-shaped through groove 801. During the process, the sliding column 804 slides inside the first arc-shaped hole 805 along the guide of the first arc-shaped hole 805, allowing the movable plate 802 to gradually pass through the arc-shaped through groove 801 and be exposed on the outside of the main body compartment 4. The four sets of movable plates 802, together with the main LED light string mechanism 12, form a square traffic sign. The second arc-shaped hole 806, together with the sliding column 804, allows the rotating disk 702 to rotate counterclockwise again without moving the movable plate 802. The actuating column 703 on the rotating disk 702, together with the fixing mechanism 6, can automatically release the fixing effect of the fixing mechanism 6 on the main LED light string mechanism 12.

[0055] like Figures 7-15 and Figure 23As shown, in this embodiment, a protective mechanism 11 is provided on the outer side of the connecting pipe 10 to cooperate with the second adjusting mechanism 8. The protective mechanism 11 includes a connecting ring 111 located on the outer side of the connecting pipe 10. The top and bottom of the connecting ring 111 are fixedly connected to the edges of the two sets of rotating disks 702, respectively. Four sets of limiting through grooves 112 are evenly opened on the inner side of the connecting ring 111. A lifting ring 113 is sleeved on the outer side of the connecting pipe 10, and four sets of connecting rods 114 are evenly installed on the outer ring of the lifting ring 113. The ends of the four sets of connecting rods 114 away from the lifting ring 113 pass through the limiting through grooves 112 and extend to the outer side of the main body compartment 4. A protective ring 115 is installed on the outer side of the main body compartment 4. Four sets of connecting rods 114 are evenly opened on the outer side of the main body compartment 4 to cooperate with the connecting rods 114. When the rotating disk 702 rotates, the connecting ring 111 rotates along with the lifting through hole 116, and the connecting rod 114 slides inside the limiting through groove 112. During the process, the limiting through groove 112 and the connecting rod 114 drive the lifting ring 113 and the protective ring 115 to move synchronously. The connecting rod 114 also moves up and down inside the lifting through hole 116. In this way, before the movable plate 802 extends out of the main body compartment 4, the protective ring 115 will no longer block the arc-shaped through groove 801. After the movable plate 802 retracts into the main body compartment 4, the protective ring 115 will automatically block the four sets of arc-shaped through grooves 801 on the outside of the main body compartment 4, preventing external dust or rainwater from entering the interior of the main body compartment 4 through the arc-shaped through grooves 801.

[0056] like Figures 1-6 , Figures 8-9 and Figure 24 As shown, in this embodiment, a photovoltaic power generation module 13 is installed on the top of the connecting mechanism 3, a storage battery 14 is installed at the bottom inside the base box 1, a control panel 15 is installed on one side inside the base box 1, a first through hole is opened at the top of the outer side of the support tube 2, a second through hole is opened on the outer side of the main body compartment 4, and a third and fourth through hole are opened on the outer side of the connecting tube 10, respectively. The storage battery 14 and the control panel 15 are allowed to enter the interior of the connecting tube 10 by passing wires through the first through hole, the second through hole, and the third through hole in sequence. A portion of the wires... It is electrically connected to two sets of power supply sockets 16. The remaining wires pass through the fourth through hole into the main body compartment 4 and are electrically connected to the servo motor 905 and the secondary LED string mechanism 803. The photovoltaic power generation module 13 continuously replenishes the battery 14 with power, and the battery 14 provides stable power to the servo motor 905, the main LED string mechanism and the secondary LED string mechanism. The mobile terminal, together with the wireless module on the control panel 15, can freely control the opening or closing of the servo motor 905, the main LED string mechanism 12 and the secondary LED string mechanism 803.

[0057] like Figures 12-13 and Figure 16As shown, in this embodiment, four sets of fixing screw holes 17 are evenly arranged on the inner wall of the main body compartment 4 near the two sets of sealing plates 5. Four sets of fixing screws 18 that cooperate with the fixing screw holes 17 are threaded on the outer edges of the two sets of sealing plates 5. Splicing blocks are symmetrically arranged at both ends of the connecting pipe 10. Splicing grooves that cooperate with the splicing blocks are symmetrically opened at the middle position of the inner side of the two sets of sealing plates 5. After the main LED light string mechanism 12 is removed from the outside of the sealing plate 5, the four sets of fixing screws 18 are unscrewed to release the fixed connection between the sealing plate 5 and the main body compartment 4. After the sealing plate 5 is separated from the main body compartment 4, the splicing groove is also separated from the splicing block. This helps the staff to inspect and maintain the components inside the main body compartment 4.

[0058] The working principle of this embodiment is as follows: The wireless terminal, in conjunction with the control panel 15 with a remote control module, controls the servo motor 905 to drive the drive gear 906 to rotate. The drive gear 906, in conjunction with the driven rack 902, drives a set of rotating disks 702 at the bottom to rotate counterclockwise, forcing the sliding column 804 to slide inside the first arc-shaped hole 805 and move from the center of the first arc-shaped hole 805 to its edge. During this process, the movable plate 802 rotates clockwise around its hinge axis connected to the arc-shaped through groove 801 until the movable plate 802 completely extends out of the arc-shaped through groove 801 to the outside of the main body compartment 4. At this time, the entire solar traffic sign changes from a circle to a square. If the control disc 702 continues to rotate counterclockwise, the sliding column 804 will slide within the second arc-shaped hole 806, and the actuating column 703 on the disc 702 will contact one end of the rotating plate 601 and push the rotating plate 601 to rotate around its hinge axis, forcing the slot 603 on the rotating plate 601 away from the trapezoidal block 604, thus releasing the restriction on the trapezoidal block 604. After that, the light panel 121 can be manually removed from the outside of the closed plate 5 and replaced with other indicator light panels 121. Alternatively, the main body compartment 4 can be rotated 90° clockwise to change the solar traffic sign from square to rhombus, and then the position of the main body compartment 4 can be fixed by tightening the wing screw 306.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
