Description

Technical Field

[0001] This invention relates to the field of LED display technology, and more specifically, to an LED display device. Background Technology

[0002] LED (Light Emitting Diode) display devices have gradually replaced traditional LCD and DLP display solutions due to their advantages such as high brightness, low power consumption, long lifespan, fast response speed, and seamless splicing, becoming the core carrier for large-size information dissemination both indoors and outdoors.

[0003] Existing LED display devices are typically assembled from modular components such as metal or plastic frames, PCB lamp boards, power supplies, and control cards. These modular components, including the PCB lamp boards, power supplies, and control cards, can form LED modules. Multiple LED modules are then detachably connected to the frame to create a larger display surface. After the physical connection is complete, electrical connections, such as cables, are used to connect the power supply and control cards of the LED modules to external electrical components. This process requires multiple steps for installation, significantly reducing installation efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide an LED display device to solve the problem of low installation efficiency of LED modules in related technologies.

[0005] To achieve the above objectives, the present invention provides an LED display device, comprising: a mounting frame including a mounting beam; a plurality of LED display modules connected to the mounting beam, the plurality of LED display modules including a first module and a second module arranged adjacent to each other in a vertical direction, a first electrical connector being provided at the end of the vertical edge of the first module near the second module, and a second electrical connector being provided at the end of the vertical edge of the second module near the first module; a first conductive element disposed on the mounting beam and having a third electrical connector, the third electrical connector being electrically connected to the first electrical connector; and a second conductive element disposed on the mounting beam and having a fourth electrical connector, the fourth electrical connector being electrically connected to the second electrical connector.

[0006] Furthermore, the mounting beam includes a mounting plate, the first conductive element includes an electrical connection plate stacked on the side of the mounting plate, and the third electrical connector is located at the end of the electrical connection plate away from the mounting frame.

[0007] Furthermore, the third electrical connector has a connecting bevel set at an angle to the electrical connection plate, and a conductive sheet is provided on the connecting bevel. The edge of the first module has a mounting bevel that mates with the connecting bevel. The first electrical connector includes conductive protrusions provided on the mounting bevel, and the conductive protrusions can make conductive contact with the conductive sheet.

[0008] Furthermore, the mounting frame includes a mounting vertical rod, and the mounting beam also includes a first half-set and a second half-set that are spliced ​​together. The first half-set and the second half-set are fitted around the outer periphery of the mounting vertical rod. The first end of the first half-set and the first end of the second half-set are both connected to the mounting plate, and the second end of the first half-set and the second end of the second half-set are detachably connected.

[0009] Furthermore, a slot is provided on one of the second ends of the first half and the second end of the second half, and an insert is provided on the other of the second ends of the first half and the second half to engage with the slot.

[0010] Furthermore, the LED display device also includes a first fastening bolt passing through the first half-set, the second half-set, and the mounting rod; and / or, the end of the electrical connection plate away from the mounting bracket is clamped between the first end of the first half-set and the mounting plate, and the LED display device also includes a second fastening bolt passing through the first half-set, the electrical connection plate, and the mounting plate.

[0011] Furthermore, the mounting beam also includes a connecting part connected to the mounting plate. The connecting part has a limiting cavity and a communicating channel connecting the limiting cavity and the outer surface of the connecting part. The first module includes a limiting plate. The limiting plate can enter or exit the limiting cavity through the communicating channel. The limiting plate can rotate around the vertical axis in the limiting cavity and engage with the inner surface of the limiting cavity to prevent detachment.

[0012] Furthermore, the limiting cavity is a spherical cavity structure, and the cross-section of the limiting plate is a circular structure.

[0013] Furthermore, the mounting beam also includes a guide seat, a horizontal angle adjustment part, a trigger part, and a shifting part; the connecting part is rotatably arranged relative to the guide seat about a horizontal axis to drive the first module to rotate synchronously about a horizontal axis; the horizontal angle adjustment part is connected to the mounting beam; the guide seat is rotatably arranged relative to the horizontal angle adjustment part about a vertical axis to drive the first module to rotate synchronously about a vertical axis through the connecting part; the trigger part is triggerably arranged on the guide seat; the shifting part can switch between a first adjustment state and a second adjustment state. When the shifting part is in the first adjustment state, the trigger part drives the connecting part to rotate through the shifting part; when the shifting part is in the second adjustment state, the trigger part drives the guide seat to rotate through the shifting part.

Multiple LED display modules are connected to the mounting beams, and the multiple LED display modules can be spliced ​​together to form a larger display surface, thereby achieving a better display effect. The multiple LED display modules include a first module and a second module arranged adjacent to each other in the vertical direction. A first electrical connector is provided at the end of the vertical edge of the first module near the end of the second module, and a second electrical connector is provided at the end of the vertical edge of the second module near the end of the first module. This arrangement allows the positions of the first electrical connector and the second electrical connector to be relatively close. A first conductive component is mounted on the mounting beam and has a third electrical connector, which is electrically connected to the first electrical connector. A second conductive component is mounted on the mounting beam and has a fourth electrical connector, which is electrically connected to the second electrical connector. This arrangement, with the first and second electrical connectors positioned close together, allows the mating third and fourth electrical connectors to be integrated onto the mounting beam. After the workers install the first and second modules onto the mounting beam, the first electrical connector directly engages with the third electrical connector, and the second electrical connector directly engages with the fourth electrical connector. This eliminates the need for workers to separately complete the electrical connections using cables or other equipment, simplifying the installation process of the LED display module and significantly improving installation efficiency. Therefore, the technical solution of this application effectively solves the problem of low installation efficiency of LED modules in related technologies. Attached Figure Description

[0042] like Figures 1 to 5 As shown, this application provides an LED display device. An embodiment of the LED display device includes: a mounting frame 10, multiple LED display modules 20, a first conductive element 30, and a second conductive element 40. The mounting frame 10 includes a mounting beam 11. The multiple LED display modules 20 are connected to the mounting beam 11. Each LED display module 20 includes a first module 21 and a second module 22 arranged adjacent to each other in the vertical direction. A first electrical connector 23 is provided at the end of the vertical edge of the first module 21 near the end of the second module 22, and a second electrical connector 24 is provided at the end of the vertical edge of the second module 22 near the end of the first module 21. The first conductive element 30 is disposed on the mounting beam 11 and has a third electrical connector 31, which is electrically connected to the first electrical connector 23. The second conductive element 40 is disposed on the mounting beam 11 and has a fourth electrical connector 41, which is electrically connected to the second electrical connector 24.

[0043] Applying the technical solution of this embodiment, the mounting frame 10 provides an installation foundation and support foundation for other components of the LED display device. The mounting frame 10 includes a mounting beam 11 so that the LED display modules 20 can be connected. Multiple LED display modules 20 are connected to the mounting beam 11, and the multiple LED display modules 20 can be spliced ​​to form a larger display surface, thereby achieving a better display effect. The multiple LED display modules 20 include a first module 21 and a second module 22 arranged adjacent to each other in the vertical direction. A first electrical connector 23 is provided at the end of the vertical edge of the first module 21 near the end of the second module 22, and a second electrical connector 24 is provided at the end of the vertical edge of the second module 22 near the end of the first module 21. This arrangement allows the positions of the first electrical connector 23 and the second electrical connector 24 to be relatively close. The first conductive element 30 is disposed on the mounting beam 11 and has a third electrical connector 31, which is electrically connected to the first electrical connector 23. The second conductive element 40 is disposed on the mounting beam 11 and has a fourth electrical connector 41, which is electrically connected to the second electrical connector 24. With this arrangement, the first electrical connector 23 and the second electrical connector 24 are positioned close together, allowing the mating third electrical connector 31 and the fourth electrical connector 41 to be integrated onto the mounting beam 11. After the workers install the first module 21 and the second module 22 onto the mounting beam 11, the first electrical connector 23 will directly complete the conductive connection with the third electrical connector 31, and the second electrical connector 24 will directly complete the conductive connection with the fourth electrical connector 41. This eliminates the need for workers to use cables or other equipment to separately complete the electrical connection, simplifying the installation steps of the LED display module 20 and greatly improving the installation efficiency. Therefore, the technical solution of this embodiment can effectively solve the problem of low installation efficiency of LED modules in related technologies.

[0044] like Figures 1 to 5 As shown, the mounting beam 11 includes a mounting plate 111, and the first conductive element 30 includes an electrical connection plate 32 stacked on the side of the mounting plate 111. The third electrical connector 31 is located at the end of the electrical connection plate 32 away from the mounting frame 10. Specifically, the first conductive element 30 is a rigid structure, unlike the commonly used flexible cable structure, and has stronger structural strength. It also ensures that the electrical connection plate 32 is not easily misaligned relative to the mounting plate 111, thus ensuring that the first conductive element 30 can smoothly achieve electrical connection with the LED display module 20 after it is connected to the mounting beam 11. In this embodiment, the structure of the second conductive element 40 is similar to that of the first conductive element 30, and will not be described in detail here. The main focus is on the structure of the first conductive element 30. One of the first conductive element 30 and the second conductive element 40 is mainly used for power supply, and the other is mainly used for signal transmission.

[0045] like Figures 1 to 5 As shown, the third electrical connector 31 has a connecting slope 311 angled to the electrical connection plate 32, and a conductive sheet 312 is provided on the connecting slope 311. The edge of the first module 21 has a mounting slope 211 that mates with the connecting slope 311. The first electrical connector 23 includes a conductive protrusion 231 provided on the mounting slope 211, which can make conductive contact with the conductive sheet 312. Specifically, the connecting slope 311 and the mounting slope 211 can cooperate with each other to avoid interference between the third electrical connector 31 and the first module 21 when the third electrical connector 31 is connected to the first electrical connector 23. The conductive protrusion 231 can make conductive contact with the conductive sheet 312, so that when the angle of the first module 21 is adjusted, the conductive protrusion 231 can always maintain point-to-surface contact with the conductive sheet 312, thereby ensuring the stability of the electrical connection and avoiding electrical connection failure.

[0046] like Figures 1 to 5 As shown, the mounting frame 10 includes a mounting vertical rod 12, and the mounting beam 11 includes a first half-set 112 and a second half-set 113 that are joined together. The first half-set 112 and the second half-set 113 are fitted around the outer periphery of the mounting vertical rod 12. The first end of the first half-set 112 and the first end of the second half-set 113 are both connected to the mounting plate 111, and the second end of the first half-set 112 and the second end of the second half-set 113 are detachably connected. Specifically, the arrangement of the first half-set 112 and the second half-set 113 enables the detachable connection between the mounting beam 11 and the mounting vertical rod 12, thereby realizing the separation of the mounting frame 10 and facilitating the installation and storage of the mounting frame 10.

[0047] like Figures 1 to 5 As shown, a slot 114 is provided on one of the second ends of the first half-set 112 and the second end of the second half-set 113, and an insert 115 is provided on the other of the second ends of the first half-set 112 and the second half-set 113, which is inserted into the slot 114. Specifically, the insert 115 and the slot 114 have the advantages of simple structure and easy mating. In addition, the LED display device also includes a first fastening bolt 51 passing through the first half-set 112, the second half-set 113 and the mounting rod 12, thereby realizing a stable connection between the first half-set 112 and the second half-set 113 and the mounting rod 12.

[0048] like Figures 1 to 5 As shown, the end of the electrical connection plate 32 away from the mounting bracket 10 is clamped between the first end of the first half-sleeve 112 and the mounting plate 111. The LED display device also includes a second fastening bolt 52 passing through the first half-sleeve 112, the electrical connection plate 32, and the mounting plate 111. Specifically, the second fastening bolt 52 can stably connect the first half-sleeve 112 and the electrical connection plate 32 to the mounting plate 111, thereby making the above components form a whole.

[0049] like Figure 6 and Figure 7 As shown, the mounting beam 11 also includes a connecting part 53 connected to the mounting plate 111. The connecting part 53 has a limiting cavity 531 and a communicating channel 532 connecting the limiting cavity 531 and the outer surface of the connecting part 53. The first module 21 includes a limiting plate 212. The limiting plate 212 can enter or exit the limiting cavity 531 through the communicating channel 532. The limiting plate 212 can rotate around a vertical axis within the limiting cavity 531 and engage with the inner surface of the limiting cavity 531 to prevent detachment. Specifically, the setting of the limiting cavity 531 and the limiting plate 212 enables quick installation and disassembly between the connecting part 53 and the first module 21. The operator only needs to let the limiting plate 212 enter the limiting cavity 531 through the communicating channel 532, and rotate the limiting plate 212 to misalign it with the communicating channel 532 to prevent the limiting plate 212 from coming out of the limiting cavity 531; the reverse operation is also true.

[0050] like Figure 6 and Figure 7 As shown, the limiting cavity 531 is a spherical cavity structure, and the limiting plate 212 has a circular cross-section. Specifically, the spherical cavity structure and the circular structure can rotate well together and are easy to manufacture.

[0051] like Figures 8 to 16 As shown, the mounting beam 11 also includes a guide seat 54, a horizontal angle adjustment part 55, a trigger part 56, and a shifting part 57; the connecting part 53 is rotatably arranged relative to the guide seat 54 about a horizontal axis to drive the first module 21 to rotate synchronously about a horizontal axis; the horizontal angle adjustment part 55 is connected to the mounting beam 11; the guide seat 54 is rotatably arranged relative to the horizontal angle adjustment part 55 about a vertical axis to drive the first module 21 to rotate synchronously about a vertical axis through the connecting part 53; the trigger part 56 is triggerably arranged on the guide seat 54; the shifting part 57 can switch between a first adjustment state and a second adjustment state. When the shifting part 57 is in the first adjustment state, the trigger part 56 drives the connecting part 53 to rotate through the shifting part 57; when the shifting part 57 is in the second adjustment state, the trigger part 56 drives the guide seat 54 to rotate through the shifting part 57.

[0052] Specifically, the above structure aims to achieve angle adjustment of the first module 21 in multiple directions (around the horizontal axis or around the vertical axis). The connecting part 53 is rotatably mounted relative to the guide seat 54 around the horizontal axis. When the operator rotates the connecting part 53, it causes the first module 21 to rotate synchronously around the horizontal axis, thereby achieving angle adjustment in one direction. The horizontal angle adjustment part 55 is connected to the mounting beam 11, and the guide seat 54 is rotatably mounted relative to the horizontal angle adjustment part 55 around the vertical axis. When the operator rotates the guide seat 54, it causes the connecting part 53 to rotate around the vertical axis, thereby causing the first module 21 to rotate synchronously around the vertical axis, thus achieving angle adjustment in another direction. The shifting part 57 has a first adjustment state and a second adjustment state, allowing the operator to select between them. When the operator selects the shifting part 57 to be in the first or second adjustment state, the operator can rotate the connecting part 53 or the guide seat 54 through the shifting part 57 when operating the trigger part 56, thereby allowing the first module 21 to rotate around the horizontal or vertical axis, thus adjusting the angle in different directions. Compared to the method of adjusting by manually rotating the module, the operator only needs to operate the shifting part 57 and the trigger part 56 to switch gears and adjust the angle, which greatly enhances the flexibility and convenience of angle adjustment.

[0053] like Figures 8 to 16 As shown, the LED display device further includes: a first transmission member 58 and a connecting part 53 connected in a transmission manner; a second transmission member 59 and a horizontal angle adjustment part 55 connected in a transmission manner; wherein, the shifting part 57 includes a mounting base 571 and a linkage member 572, the linkage member 572 being movably disposed on the mounting base 571. When the shifting part 57 is in a first adjustment state, the linkage member 572 is connected in a transmission manner between the first transmission member 58 and the trigger part 56, and the second transmission member 59 is separated from the trigger part 56. When the shifting part 57 is in a second adjustment state, the linkage member 572 is connected in a transmission manner between the second transmission member 59 and the trigger part 56, and the first transmission member 58 is separated from the trigger part 56. Specifically, the function of the linkage 572 is to realize the transmission cooperation between the trigger part 56 and different transmission parts. By moving the linkage 572, the operator can make the linkage 572 drive the first transmission part 58 and the trigger part 56 or drive the second transmission part 59 and the trigger part 56. Thus, when the operator operates the trigger part 56, the movement can be transmitted to the first transmission part 58 or the second transmission part 59 through the linkage 572, thereby driving the connecting part 53 to rotate or driving the guide seat 54 to rotate.

[0054] like Figures 8 to 16As shown, the first transmission member 58 is provided with a first groove segment 581, the second transmission member 59 is provided with a second groove segment 591, and the trigger part 56 is provided with a third groove segment 561. The first groove segment 581, the third groove segment 561, and the second groove segment 591 can be connected in sequence to form a first sliding groove. The linkage member 572 includes a first slider 573 that can slide in the first sliding groove. When the shifting part 57 is in the first adjustment state, the first slider 573 is located in the first groove segment 581 and the third groove segment 561. When the shifting part 57 is in the second adjustment state, the first slider 573 is located in the second groove segment 591 and the third groove segment 561. Specifically, the first slider 573 is located within the first groove segment 581 and the third groove segment 561. The first slider 573 abuts against the side walls of both the first groove segment 581 and the third groove segment 561. At this time, the movement of the trigger part 56 will drive the first transmission member 58 to move synchronously, thereby realizing the transmission of motion. Similarly, the first slider 573 is located within the second groove segment 591 and the third groove segment 561. The first slider 573 abuts against the side walls of both the second groove segment 591 and the third groove segment 561. At this time, the movement of the trigger part 56 will drive the second transmission member 59 to move synchronously, thereby realizing the transmission of motion. More specifically, the trigger part 56 includes a lead screw 562 and a sliding block 563. The lead screw 562 passes through the sliding block 563 and is threadedly engaged with the sliding block 563. The third groove segment 561 and the sixth groove segment 564 (mentioned later) are disposed on the sliding block 563. The operator rotates the lead screw 562, which drives the sliding block 563 to move in translation. The sliding sleeve 582 of the first transmission component 58 (mentioned later) and the transmission rod 592 of the second transmission component 59 (mentioned later) can move in translation synchronously with the sliding block 563, thereby realizing the transmission of motion.

[0055] like Figures 8 to 16As shown, the shifting part 57 also includes a second slider 574. The first transmission member 58 is provided with a fourth groove segment 585, the second transmission member 59 is provided with a fifth groove segment 594, the trigger part 56 is provided with a sixth groove segment 564, and the guide seat 54 is provided with a seventh groove segment and an eighth groove segment. The seventh groove segment, the fourth groove segment 585, the sixth groove segment 564, the fifth groove segment 594, and the eighth groove segment can be connected in sequence to form a second slide groove. The second slider 574 can slide in the second slide groove. When the shifting part 57 is in the first adjustment state, the second slider 574 is located in the fifth groove segment 594 and the eighth groove segment. When the shifting part 57 is in the second adjustment state, the first slider 573 is located in the seventh groove segment and the fourth groove segment 585. Specifically, the second slider 574 functions as a "locking" mechanism. When the shifting unit 57 is in the first adjustment state, it is not desirable for the second transmission member 59 to move. The second slider 574 is locked within the fifth slot 594 and the eighth slot, thereby locking the second transmission member 59 and the guide seat 54 together and preventing the second transmission member 59 from moving erroneously. In this state, only the first transmission member 58 moves with the triggering unit 56. Similarly, when the shifting unit 57 is in the second adjustment state, it is not desirable for the first transmission member 58 to move. The second slider 574 is locked within the seventh slot and the fourth slot 585, thereby locking the first transmission member 58 and the guide seat 54 together and preventing the first transmission member 58 from moving erroneously. In this state, only the second transmission member 59 moves with the triggering unit 56.

[0056] like Figures 8 to 16 As shown, the first slide groove and the second slide groove are arranged parallel to each other. The shifting part 57 also includes a rocker arm 575, the pivot of which is located between the first slide groove and the second slide groove. The first slider 573 and the second slider 574 are located at opposite ends of the rocker arm 575. Specifically, the rocker arm 575 allows the operator to move both the first slider 573 and the second slider 574 simultaneously, eliminating the need to operate them separately.

[0057] like Figures 8 to 16 As shown, the first transmission component 58 includes a sliding sleeve 582 and a first swing arm 583. The connecting part 53 includes an adjusting block 533 connected to the first module 21. The sliding sleeve 582 is movably sleeved on the outside of the trigger part 56. A pin 584 is provided on the sliding sleeve 582. The first swing arm 583 is rotatably arranged around a transverse axis. The pin 584 is inserted into one end of the first swing arm 583, and the other end of the first swing arm 583 is rotatably connected to the adjusting block 533. Specifically, the first swing arm 583 can convert the translational movement of the sliding sleeve 582 into the swing of the adjusting block 533, so that the adjusting block 533 can drive the first module 21 to rotate around a transverse axis, which is the axis around which the adjusting block 533 rotates.

[0058] like Figures 8 to 16 As shown, the second transmission component 59 includes a transmission rod 592 and a second swing arm 593. The horizontal angle adjustment part 55 includes an adjustment arm 551 connected to the mounting beam 11. The transmission rod 592 can move synchronously with the trigger part 56. The second swing arm 593 is rotatably arranged around a vertical axis. One end of the transmission rod 592 is rotatably connected to the second swing arm 593, and the other end of the second swing arm 593 is rotatably connected to the adjustment arm 551. Specifically, the transmission rod 592 can move in translational motion following the sliding block 563. The arrangement of the second swing arm 593 converts the translational motion into the rotation of the adjustment arm 551. The guide seat 54 is provided with a guide groove 541. The adjustment arm 551 is guided and engaged with the guide groove 541. At this time, the adjustment arm 551 is actually stationary, and the guide seat 54 rotates (relative motion). The rotation of the guide seat 54 drives the adjustment block 533 to rotate around the vertical axis, thereby driving the first module 21 to rotate around the vertical axis. The vertical axis is the axis around which the guide seat 54 rotates. Specifically, the second swing arm 593 is a plate-shaped structure, and a hinge point is provided on the second swing arm 593 to be hinged to the guide seat 54.

[0059] Furthermore, the shifting unit 57 can also switch to a third adjustment state. When the shifting unit 57 is in the third adjustment state, the trigger unit 56 drives the connecting unit 53 and the guide seat 54 to rotate simultaneously through the shifting unit 57; the linkage member 572 is driven between the first transmission member 58 and the trigger unit 56, and the linkage member 572 is driven between the second transmission member 59 and the trigger unit 56; the first slider 573 is located in the first groove segment 581, the third groove segment 561, and the second groove segment 591. That is to say, the shifting unit 57 also includes a third adjustment state, in which the angles of the first module 21 in two directions can be adjusted simultaneously. Specifically, this is achieved as follows: In this adjustment state, the first slider 573 is located within the first groove segment 581, the third groove segment 561, and the second groove segment 591. The first slider 573 simultaneously abuts against the side walls of the first groove segment 581, the third groove segment 561, and the second groove segment 591, thus enabling the sliding block 563 to move horizontally. The sliding sleeve 582 of the first transmission member 58 and the transmission rod 592 of the second transmission member 59 move horizontally synchronously with the sliding block 563, thereby achieving angle adjustment in two directions. Furthermore, in this adjustment state, the second slider 574 will not engage with the seventh groove segment or the eighth groove segment, so the second slider 574 will not perform a "locking" function.

[0060] In the description of this invention, it should be understood that "a plurality of" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing the invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0062] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
