Technical Field

[0001] This application relates to the field of manufacturing and application of low-voltage electrical products, and in particular to an automatic transfer switch. Background Technology

[0002] Automatic transfer switches, also known as dual-power automatic transfer switches, are mainly used to connect or disconnect load equipment from a first or second circuit via motor control or manual control, ensuring the normal operation of the load equipment.

[0003] However, the automatic transfer switches commonly found on the market today use a lot of parts, are relatively complex to assemble, are inconvenient to disassemble and repair, and have weak expandability. Summary of the Invention

[0004] This application provides an automatic transfer switch that can solve the problems of existing automatic transfer switches having many parts, complex assembly, inconvenient disassembly and maintenance, and weak scalability.

[0005] The technical solution of this application is an automatic changeover switch, comprising: a controller, a rotating component, a sliding plate and a moving contact assembly that are detachably connected in sequence, and a stationary contact assembly that is movably connected to the moving contact assembly;

[0006] The rotating component is configured to be driven by the controller to rotate around a first preset vertical direction and has a downwardly extending push rod provided at a non-first preset direction on its lower end face;

[0007] The slide plate is configured as a plate, extends in a horizontal second preset direction, can slide along the second preset direction, has a push groove recessed at the top for the push rod to be inserted, and when the rotating member rotates, the push rod drives the slide plate to slide through the push groove, and a rotation groove is recessed on the main extension surface of the slide plate;

[0008] The moving contact assembly includes: a plurality of moving contacts arranged side by side, and a rotating rod disposed at one end of the arrangement direction of the plurality of moving contacts, which can be inserted into the rotating groove, can rotate along a direction perpendicular to the main extension surface of the slide plate, and drives the moving contact assembly to rotate through the rotating groove until the moving contact assembly abuts against the stationary contact assembly when the slide plate slides.

[0009] Optionally, it further includes: a starter gear that can rotate about a third preset direction parallel to the first preset direction, can mesh with the rotating component and drive the rotating component to rotate, and a motor that can be driven by the controller to rotate the starter gear;

[0010] The rotating component, sliding plate, moving contact assembly, and stationary contact assembly are all provided in pairs, and are symmetrically arranged on both sides of the starting gear with a direction parallel to the second preset direction and perpendicular to the third preset direction as the axis.

[0011] In this configuration, the arrangement direction of several moving contacts in the moving contact assembly is perpendicular to the main extension surface of the slide plate, and the rotating groove into which the rotating rod is inserted is located on the side of the slide plate away from the starting gear, and the motor is located between the two moving contact assemblies.

[0012] Furthermore, the rotating component is a sector gear, and the starting gear is configured as a non-full-tooth gear so that it only meshes with one rotating component when the starting gear rotates clockwise or counterclockwise.

[0013] Optionally, the moving contact extends in a direction perpendicular to the arrangement direction of the plurality of moving contacts;

[0014] Furthermore, the moving contact assembly further includes: a contact support frame sleeved on the outside of a plurality of moving contacts and having evenly spaced holes for the moving contacts to extend out, and spring sheets disposed within the holes and clamped on both sides of the moving contacts to maintain the extension direction of the moving contacts.

[0015] Optionally, it also includes: a housing;

[0016] The housing includes:

[0017] The gear set housing is located at the upper end of the rotating component and the starting gear; the frame housing is located at the lower end of the rotating component and the starting gear and is assembled with the gear set housing to form a support structure; the contact assembly housing is located at the bottom end of the slide plate, the moving contact assembly, the stationary contact assembly and the motor and is assembled with the lower end of the frame housing to form a support structure.

[0018] The contact assembly housing is provided with a side wall that has a recessed sliding groove for the sliding plate to slide.

[0019] In addition, the housing also includes:

[0020] The controller lower housing is detachably connected to a side wall of the sliding plate in the contact assembly housing, which is parallel to the arrangement direction of the plurality of moving contacts and is used to make the separated moving contact assembly and stationary contact assembly continuously move closer together during sliding, and the controller upper housing is detachably connected to the controller lower housing and forms a support structure with the controller lower housing to surround the controller.

[0021] Optionally, it further includes: a handle disposed on the upper end face of the gear set housing and drivenly connected to the starter gear for manually controlling the rotation of the starter gear.

[0022] Optionally, a first slide rail is provided in the vertical direction at the detachable connection between the contact assembly housing and the upper housing of the controller, and a second slide rail is provided on the upper housing of the controller to cooperate with the first slide rail.

[0023] Optionally, the side wall of the contact assembly housing with the sliding groove has a vertically extending channel recessed between the sliding groove and the side wall connected to the upper housing of the controller.

[0024] Additionally, the skateboard has a connecting rod and a spring on the side closer to the controller;

[0025] The connecting rod is configured such that one end is cylindrical and is vertically and movably connected to the slide plate, and the other end is cylindrical and is pressed against the top of a spring that can extend and retract in the vertical direction, inserted into the channel in a direction perpendicular to the main extension surface of the slide plate, and slidably connected to the channel in the vertical direction.

[0026] Furthermore, the contact assembly housing is provided with a spring groove for the extension and retraction of the spring;

[0027] When it is necessary for the moving contact assembly to abut against the stationary contact assembly, the rotating part is indirectly rotated by the controller or handle, causing the slide plate to slide. During the sliding process of the slide plate, on the projection along the direction perpendicular to the main extension surface of the slide plate, the line connecting the two ends of the connecting rod, which are set in a cylindrical shape, follows the slide plate from tilting away from the side of the controller upper housing to tilting towards the side of the controller upper housing.

[0028] Optionally, the controller is provided with two closed state micro switches and two open state micro switches on the side near the start gear, which are symmetrically arranged with an axis parallel to the second preset direction and perpendicular to the third preset direction.

[0029] When neither of the rotating parts on either side of the starting gear is rotating and neither the moving contact assembly nor the stationary contact assembly is connected, the sidewalls of the two slide plates near the rotating parts press against the closed state micro switch to transmit closed state information to the controller.

[0030] When the rotating member located on either side of the starting gear rotates and the moving contact assembly abuts against the stationary contact assembly, a micro switch for the starting state is pressed against the side wall of the rotating member at the top of the slid-out slide plate, for transmitting starting state information to the controller.

[0031] In summary, this application provides an automatic transfer switch, comprising: a controller, a rotating component, a sliding plate, and a moving contact assembly, all detachably connected in sequence, as well as a stationary contact assembly. The rotating component is configured to be rotatable and has a push rod on its lower end face. The sliding plate is configured to be slidable, with a push groove recessed at its top for the push rod to insert into, and the push rod drives the sliding plate to slide through the push groove; the sliding plate also has a rotation groove recessed on it. The moving contact assembly includes: a plurality of moving contacts, and a rotating rod that can be inserted into the rotation groove, is rotatable, and drives the moving contact assembly to rotate. Because this application uses fewer parts, assembly is very simple, greatly saving production and usage costs. Furthermore, because the controller is detachably connected in this application, it can be easily disassembled and assembled to accommodate different types of controllers, improving the flexibility and scalability of this application. Therefore, this application can solve the problems of existing automatic transfer switches having many parts, complex assembly, inconvenient disassembly and maintenance, and weak scalability.

Detailed Implementation

[0054] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims. Furthermore, all drawings in the embodiments of this application refer to the same coordinate system.

[0055] This application provides an automatic transfer switch, such as... Figure 1 , Figure 2 As shown, Figure 1 This is a schematic diagram of an automatic transfer switch according to an embodiment of this application. Figure 2 This is a schematic diagram of an automatic transfer switch according to an embodiment of the present application, including: controller 1, rotating component 2, sliding plate 3, moving contact assembly 4, stationary contact assembly 5, starting gear 6, motor 7, housing 8, and handle 9.

[0056] (I) Structural Description

[0057] The automatic transfer switch is functionally grouped as follows: Controller 1 and motor 7 work together to form a motor control structure, which provides driving force for switch switching; handle 9 and motor 7 work together to form a manual control structure, which also provides driving force for switch switching; two rotating parts 2 and starting gear 6 work together to form a two-way switching mechanism, which is driven and drives the slide plate 3 as an actuating mechanism; slide plate 3 is an actuating mechanism, which is used to adjust the connection and separation of moving contact assembly 4 and stationary contact assembly 5; housing 8 is a protective structure, which is used to protect the remaining components.

[0058] Structural grouping of the rotary changeover switch: The housing 8 divides the switch in the embodiment of this application into three parts.

[0059] like Figure 2 , Figure 3 and Figure 4 As shown, Figure 3This is a schematic diagram of the shell structure in an embodiment of this application. Figure 4 This is a schematic diagram of the controller and the upper housing of the controller in the embodiment of this application. The housing 8 includes: gear set housing 81, frame housing 82, contact assembly housing 83, lower housing of the controller 84 and upper housing of the controller 85.

[0060] The upper sides of the gear housing 81 and the frame housing 82 are assembled together to form the first support structure, which is used to support and protect the rotating part 2 and the starting gear 6; the lower side of the frame housing 82 is assembled with the contact assembly housing 83 to form the second support structure, which is used to support and protect the sliding plate 3, the moving contact assembly 4, the stationary contact assembly 5 and the motor 7; the lower housing 84 and the upper housing 85 of the controller are assembled with the contact assembly housing 83 to form the third support structure, which is used to support and protect the controller 1.

[0061] Both the lower housing 84 and the upper housing 85 of the controller are detachably connected to a side wall of the contact assembly housing 83, which is parallel to the arrangement direction of several moving contacts 41 and is used to make the slide plate 3, which is separated from the moving contact assembly 4 and the stationary contact assembly 5, continuously move closer together during sliding.

[0062] The contact assembly housing 83 and the upper housing 85 of the controller are detachably connected with a first slide rail 832 in the vertical direction, and the upper housing 85 of the controller is provided with a second slide rail 851 that works in conjunction with the first slide rail 832, so that the controller 1 can be disassembled and installed by simply removing and installing the upper housing 85 of the controller when the automatic transfer switch is in the installation state.

[0063] The first preset direction is the central axis of the rotating component 2 when the sector gear rotates, and the third preset direction is the central axis of the starting gear 6 when it rotates.

[0064] In the direction of extension against the y-axis, the controller 1, the rotating component 2, the starting gear 6, and the slide plate 3 are arranged in sequence. In the direction of extension along the x-axis, the moving contact assembly 4, the stationary contact assembly 5, the slide plate 3, the rotating component 2, and the starting gear 6 are arranged in sequence.

[0065] Rotating component 2 is a horizontally arranged sector gear, and there are two of them. Starting gear 6 is a horizontally arranged non-full-tooth gear, such as... Figure 5 and Figure 6 As shown, Figure 5 This is a top view of the embodiment of this application when the starting gear does not drive the rotating component to rotate. Figure 6This is a top view of the rotating component after the starting gear drives it to rotate in this embodiment of the application. The starting gear 6 is disposed between the two rotating components 2 and is arranged along the x-axis extension direction with the two rotating components 2. The gear portions of the rotating components 2 and the starting gear 6 are arranged opposite to the y-axis, and when the starting gear 6 is driven to rotate clockwise or counterclockwise and drives the rotating component 2 on either side to rotate, it only meshes with and drives one of the rotating components 2 to rotate.

[0066] The automatic transfer switch is configured as follows: When neither the rotating component 2 nor the starting gear 6 is rotating and the moving contact assembly 4 is not in contact with the stationary contact assembly 5, the automatic transfer switch is in position 0, i.e., the automatic transfer switch is in the off state. When the starting gear 6 rotates clockwise and drives one of the rotating components 2 to rotate counterclockwise until one moving contact assembly 4 and one stationary contact assembly 5 come into contact, the automatic transfer switch is in position I, i.e., the automatic transfer switch is in the on state. When the starting gear 6 rotates counterclockwise and drives another rotating component 2 to rotate clockwise until another moving contact assembly 4 and another stationary contact assembly 5 come into contact, the automatic transfer switch is in position II, i.e., the automatic transfer switch is in the on state.

[0067] The automatic transfer switch is structurally positioned as follows: Two of each of the rotating component 2, sliding plate 3, moving contact assembly 4, and stationary contact assembly 5 are arranged symmetrically on both sides of the starter gear 6, with an axis parallel to the second preset direction and perpendicular to the third preset direction. The relative positions of the rotating component 2, sliding plate 3, moving contact assembly 4, and stationary contact assembly 5, arranged in front of the starter gear 6 against the x-axis extension direction, are now explained as an example.

[0068] Each stationary contact assembly 5 includes two sets of stationary contacts symmetrically arranged on both sides of the moving contact assembly 4. Each set of stationary contacts includes 8 stationary contacts, for a total of 16 stationary contacts in both sets.

[0069] The starter gear 6 has an inner hole in the center that is connected to the output shaft of the motor 7 located below the starter gear 6. The controller 1 can drive the starter gear 6 to rotate around the third preset direction by controlling the motor 7. The top of the starter gear 6 is connected to the handle 9 located on the upper surface of the gear set housing 81. Turning the handle 9 can also start the motor 7 to drive the starter gear 6 to rotate around the third preset direction.

[0070] A downwardly extending push rod 21 is provided on the lower end face of the rotating component 2 at a position other than the first preset direction, such as... Figure 7 As shown, Figure 7This is a schematic diagram showing the connection between the rotating component and the starting gear in an embodiment of this application. The central axis of the rotating component 2 is fixed on the gear set housing 81, and the rotating component 2 is rotatably connected to the gear set housing 81. The push rod 21 is cylindrical in shape.

[0071] The slide plate 3 is positioned in front of the rotating member 2 in the direction opposite to the y-axis, in front of the rotating member 2 in the direction opposite to the x-axis, and below the rotating member 2 in the direction opposite to the z-axis. For example... Figure 7 and Figure 8 As shown, Figure 8 This is a schematic diagram of the connection between the slide plate and the contact assembly housing in an embodiment of this application. The contact assembly housing 83 has a recessed sliding groove 831 for the slide plate 3 to slide.

[0072] The slide plate 3 is plate-shaped, extending in a second predetermined horizontal direction parallel to the y-axis, positioned in front of the rotating member 2 in the opposite direction to the y-axis, slidable along the second predetermined direction and passing the rotating member 2 away from the starting gear 6, with a push groove 31 recessed at its top for inserting a push rod 21, and when the rotating member 2 rotates, the push rod 21 drives the slide plate 3 to slide through the push groove 31; and the slide plate 3 has a rotation groove 32 recessed on its main extension surface in the opposite direction to the x-axis. The rotation groove 32 is located on the side of the slide plate 3 away from the starting gear 6.

[0073] The skateboard 3 has a connecting rod 33 and a spring 34 on the side near the controller 1, such as... Figure 9 As shown, Figure 9 This is a schematic diagram showing the connection of the connecting rod and spring in the 0-position state in this embodiment. The side wall of the contact assembly housing 83, which has a sliding groove 831, has a vertically extending channel 833 recessed between the sliding groove 831 and the side wall connected to the controller upper housing 85. The contact assembly housing 83 also has a spring groove 834 for the extension and retraction of the spring 34. The connecting rod 33 is configured such that one end is cylindrical and vertically movably connected to the slide plate 3, and the other end is cylindrical and pressed against the top of the vertically extendable spring 34, inserted into the channel 833 in a direction perpendicular to the main extension surface of the slide plate 3, and slidably connected to the channel 833 in the vertical direction.

[0074] When it is necessary to make the moving contact assembly 4 abut against the stationary contact assembly 5, the rotating part 2 is indirectly rotated through the controller 1 or the handle 9, which drives the slide plate 3 to slide. During the sliding of the slide plate 3, the setting direction of the connecting rod 33 changes from tilting away from the controller upper housing 85 to tilting towards the controller upper housing 85.

[0075] The moving contact assembly 4 includes: a moving contact 41, a rotating rod 42, a contact support frame 43, and a spring plate 44, as shown below. Figure 10 As shown, Figure 10 This is a schematic diagram of the moving contact assembly in an embodiment of this application. A plurality of moving contacts 41 are arranged side by side along the x-axis extension direction, and the moving contacts 41 extend in a direction perpendicular to the arrangement direction of the plurality of moving contacts 41. When the automatic changeover switch is in the 0 position, the moving contacts 41 extend in the opposite direction to the y-axis extension direction.

[0076] The rotating rod 42 is arranged in the direction of the arrangement of several moving contacts 41 towards one end of the slide plate 3, can be inserted into the rotating slot 32 and can rotate in a direction perpendicular to the main extension surface of the slide plate 3. When the automatic changeover switch is switched from the 0 position to the I position, on the projection along the extension direction of the x-axis, the line connecting the rotating rod 42 and the central axis of the moving contact assembly 4 rotates from tilting away from the rotating member 2 to tilting towards the rotating member 2. That is, the rotating rod 42 rotates from being located on the right side of the central axis of the moving contact assembly 4 to being located on the left side of the central axis of the moving contact assembly 4.

[0077] A contact support frame 43 is sleeved on the outside of several moving contacts 41 and has evenly spaced holes for the moving contacts 41 to extend out. Spring plates 44 are disposed in the holes and clamped on both sides of the moving contacts 41 to maintain the extension direction of the moving contacts 41.

[0078] The controller 1 is equipped with four microswitches arranged in two rows side by side. The controller 1 is also equipped with two closed microswitches 11 and two open microswitches 12 that are close to the start gear 6 and far away from the start gear 6, respectively, with the direction parallel to the second preset direction and perpendicular to the third preset direction as the axis.

[0079] When neither of the rotating parts 2 on either side of the start gear 6 is rotating and neither the moving contact assembly 4 nor the stationary contact assembly 5 is connected, the tops of the two slide plates 3 near the side walls of the rotating parts 2 press against the horizontally extendable contact piece of the micro switch 11 in the closed state, which is used to transmit the closed state information to the controller 1; when the rotating part 2 on either side of the start gear 6 rotates and the moving contact assembly 4 and the stationary contact assembly 5 come into contact, a micro switch 12 in the start state is pressed against the horizontally extendable contact piece of the micro switch 12 in the start state at the top of the slide plate 3 near the side wall of the rotating part 2, which is used to transmit the start state information to the controller 1.

[0080] (II) Working Principle

[0081] The working principle of this application embodiment is explained by taking the rotating component 2, the sliding plate 3, the moving contact assembly 4 and the stationary contact assembly 5, which are arranged in front of the starting gear 6 in the opposite direction of the x-axis extension, as an example. That is, the process of the automatic transfer switch switching from the 0 position state to the 1 position state, and the process of the automatic transfer switch switching from the 1 position state back to the 0 position state.

[0082] (1) 0-bit state

[0083] When neither the rotating component 2 nor the starting gear 6 is rotating and the moving contact assembly 4 is not in contact with the stationary contact assembly 5, the automatic transfer switch is in the 0 position, that is, the automatic transfer switch is in the closed position.

[0084] like Figure 9 , Figure 11 and Figure 12 As shown, Figure 11 This is a connection diagram of the rotating component, sliding plate, moving contact assembly, and stationary contact assembly in the 0 position state in an embodiment of this application. Figure 12 for Figure 11 A partial schematic diagram of part A shows that the connecting rod 33 is pressed onto the spring 34. The spring 34 pushes the connecting rod 33 to lock the slide plate 3 on the side near the upper housing 85 of the controller to limit the sliding of the slide plate 3 and to make the slide plate 3 lock the push rod 21 of the rotating member 2 through the push groove 31 so that the rotating member 2 cannot move without being subjected to external force.

[0085] The top of the slide plate 3 is pressed against the side wall of the rotating part 2 to press the contact piece of the micro switch 11, which is horizontally arranged in the closed state, so as to transmit the closed state information to the controller 1.

[0086] (2) 0-bit state → 1-bit state

[0087] When the starting gear 6 rotates clockwise, it drives the rotating part 2 to rotate counterclockwise.

[0088] like Figure 13 , Figure 14 and Figure 15 As shown, Figure 13 This is a connection diagram illustrating the process of the rotating component, sliding plate, moving contact assembly, and stationary contact assembly rotating from the 0-position state to the 1-position state in an embodiment of this application. Figure 14 for Figure 13 A partial schematic diagram of part B in the middle section. Figure 15This is a schematic diagram of the connection between the connecting rod and the spring during the rotation from the 0 position to the 1 position in this embodiment. The controller 1 or the handle 9 causes the starting gear 6 to rotate clockwise and drives the rotating part 2 to rotate counterclockwise, causing the slide plate 3 to slide in the sliding groove 831 and change the relative position of the rotating groove 32 and the rotating rod 42. During the sliding of the slide plate 3, the setting direction of the connecting rod 33 changes from tilting away from the controller upper housing 85 to tilting towards the controller upper housing 85. At a certain moment during the change, the setting direction of the connecting rod 33 is parallel to the elastic direction of the spring 34, at which time the compression of the spring 34 reaches its maximum.

[0089] (3) I-bit state

[0090] When the starting gear 6 rotates clockwise and drives the rotating part 2 to rotate counterclockwise until the moving contact assembly 4 and the stationary contact assembly 5 come into contact, the automatic transfer switch is in position I, that is, the automatic transfer switch is in the start state.

[0091] like Figure 16 , Figure 17 and Figure 18 As shown, Figure 16 This is a schematic diagram showing the connection of the rotating component, sliding plate, moving contact assembly, and stationary contact assembly in the I-position state in an embodiment of this application. Figure 17 for Figure 16 A partial schematic diagram of section C. Figure 18 This is a schematic diagram of the connection between the connecting rod and the spring in the I position in the embodiment of this application. When the spring 34 is compressed to the maximum extent, the spring 34 quickly releases the potential energy generated by the compression, pulling the slide plate 3 to slide faster towards the upper housing 85 of the controller in the sliding groove 831.

[0092] During the sliding process, the slide plate 3 continues to drive the rotating rod 42 to rotate through the rotating groove 32 until the moving contact assembly 4 comes into contact with the stationary contact assembly 5.

[0093] The automatic selector switch is in the active state, and spring 34 engages the slide plate 3 near the controller housing 85 to limit its movement. At this time, the top of the slide plate 3, near the side wall of the rotating component 2, presses against the horizontally positioned contact of the active state micro switch 12 to transmit active state information to the controller 1.

[0094] (4) I-bit state → 0-bit state

[0095] like Figure 19 and Figure 20 As shown, Figure 19 This is a connection diagram illustrating the process of rotating the rotating component, sliding plate, moving contact assembly, and stationary contact assembly from the I-position to the 0-position in an embodiment of this application. Figure 20 for Figure 19 A partial schematic diagram of part D shows that the starting gear 6 is rotated counterclockwise by the controller 1 or the handle 9, which in turn drives the rotating part 2 to rotate clockwise. This causes the slide plate 3 to slide in the sliding groove 831 and changes the relative position of the rotating groove 32 and the rotating rod 42. During the sliding of the slide plate 3, the setting direction of the connecting rod 33 changes from tilting towards the side closer to the controller upper housing 85 to tilting away from the controller upper housing 85.

[0096] (5) II bit state

[0097] The working principle of the automatic transfer switch in the switching process between the II state and the 0 state is the same as that in the switching process between the I state and the 0 state, so it will not be described again.

[0098] In summary, this application provides an automatic changeover switch, comprising: a controller 1, a rotating member 2, a sliding plate 3, and a moving contact assembly 4, which are sequentially and detachably connected, and a stationary contact assembly 5 movably connected to the moving contact assembly 4. The rotating member 2 is configured to rotate about a first preset vertical direction and has a downwardly extending push rod 21 at a non-first preset direction on its lower end face. The sliding plate 3 is configured to slide along a second preset direction, has a push groove 31 recessed at its top for the push rod 21 to insert into, and when the rotating member 2 rotates, the push rod 21 drives the sliding plate 3 to slide through the push groove 31; and a rotating groove 32 is recessed on the main extension surface of the sliding plate 3. The moving contact assembly 4 includes: a plurality of moving contacts 41, and a rotating rod 42 disposed at one end of the arrangement direction of the plurality of moving contacts 41, which can be inserted into the rotating groove 32, rotates along a direction perpendicular to the surface of the sliding plate 3, and drives the moving contact assembly 4 to rotate through the rotating groove 32 until the moving contact assembly 4 abuts against the stationary contact assembly 5 when the sliding plate 3 slides. Because the embodiments of this application use fewer parts, the assembly is very simple, which greatly saves production and usage costs. Also, because the controller 1 is detachable in the embodiments of this application, the controller 1 can be easily disassembled and assembled to adapt to the installation of different types of controllers, which improves the flexibility and scalability of the embodiments of this application.

[0099] The embodiments of this application have been described in detail above, but the content is only a preferred embodiment of this application and should not be considered as limiting the scope of this application. All equivalent changes and improvements made within the scope of this application should still fall within the patent coverage of this application.
