Description

Technical Field

[0001] The invention relates to a door arrangement, a method for connecting a container to an isolation chamber and a system comprising a door arrangement and a container. Background Art

[0002] European Patent No. EP 1 440 448 B1 discloses a door device with a double bayonet lock, which consists of two bayonet locks of different chirality. The container is locked or unlocked on the door frame by rotating a handle connected to the container flange. Summary of the Invention

[0003] It is therefore an object of the present invention to improve the connection between a container and an isolation chamber.

[0004] This object is achieved by a door arrangement according to the features of patent claim 1. Claims 8 and 10 provide a system with a door arrangement as described herein and a method for connecting a container to an isolation chamber via a protective connection as described herein. The dependent claims relate to further advantageous embodiments.

[0005] In one embodiment of the present invention, a door arrangement is provided or used for a preferably tight, in particular preferably sterile and / or airtight and / or watertight, connection of a container to an isolation chamber, and is provided with a door frame, which in one embodiment consists of several parts and in one embodiment defines an insulating space or is provided or used for this purpose, and is further provided with a door leaf that is reversibly adjustable from a closed position (in which the door arrangement or door frame access opening is closed) to an open position (in which the access opening is opened), preferably in a pivotable manner, particularly preferably in a horizontally pivotable manner. In one embodiment, the door leaf is preferably pivotably mounted on the door frame.

[0006] Thus, in one embodiment, advantageous, in particular compact, simple and / or reliable opening and closing kinematics can be achieved.

[0007] In one embodiment of the present invention, the container to be connected, in particular a temporarily or non-destructively removable container, has a plurality of radial flanges evenly distributed around its circumference, in one embodiment at least two, preferably at least three, particularly preferably at least four, and in one embodiment a maximum of six, in one embodiment radially outer flanges or radially outwardly extending (away) from the container flanges, and a lid for closing the container inlet and / or outlet openings, which is typically fixed to the container, in particular for temporarily or non-destructively removable containers, or a fixing method or arrangement for this purpose. In one embodiment, the interior of the container with the lid forms an airtight transport space, in one embodiment, a sterile transport space particularly suitable for medical devices, small parts, etc. In one embodiment, the container inlet and / or outlet openings connected to the door device at least partially overlap with the door device passage opening, so that goods can be moved into or out of the container through these openings.

[0008] Thus, in one embodiment, the containers are connected in such a manner that the contents of the containers can be moved into or from an isolation chamber separated from the space outside the tray or container while maintaining sterility.

[0009] In one embodiment of the invention, it is provided that the door has an interface and the lid has a counter-interface of a lock, which in a preferred embodiment is a bayonet lock, which in this case is called an unrestricted first bayonet lock, by means of which the lid can be fixed to the door, in particular temporarily or non-destructively removable to the door, or is provided or used for this purpose.

[0010] Thus, in one embodiment, the lid can be transferred from the container to the door and moved through or with the lid to open or close the container inlet and / or outlet openings connected to the door arrangement. In particular, in one embodiment, the lid can be manipulated advantageously, preferably sterilely, by actuating the door from the container receiving space or from the side of the container. The bayonet lock is particularly well-suited for this purpose due to its reliability and kinematic properties.

[0011] According to one embodiment of the present invention, the door frame has several axial grooves for inserting the radial flange of the container, at least two in one embodiment, preferably at least three, in particular at least four, and at most six in one embodiment, in which the radial flange of the container is (guided) to be (axially) inserted in a form-fitting manner, especially in the case of temporary or non-destructive detachability, its radial flange will be (axially) inserted into or provided for this purpose or used in the axial groove.

[0012] In one embodiment, "axial" refers to the insertion or longitudinal direction of the axial groove and / or refers to the preferred common rotation axis direction of a cover plate and / or actuator, "circumferential" refers to the rotation direction around the axial (longitudinal) axis, and in one embodiment refers to the symmetry axis or rotation axis direction of the container flange, and "radial" refers to the direction perpendicular to the axial and circumferential directions.

[0013] According to one embodiment of the invention, the door arrangement comprises a single-piece or multi-piece cover plate, which can be reversibly adjusted from an inserted position (in which the axial groove for inserting and removing the radial flange is removed) into a locked position, preferably rotatable, particularly preferably about an axial axis or rotational axis. In this locked position, the cover plate locks the axial groove and prevents displacement of the radial flange. In one embodiment, the container is locked to the door arrangement by a form fit and / or a friction fit. In one embodiment, the cover plate is mounted on the door frame after a corresponding adjustment, in particular a rotational adjustment.

[0014] Thus, in one embodiment, the bayonet lock described in European Patent EP 1 440 448 B1 at the outset, which requires rotating the container handle for locking or unlocking, is replaced by an operation of rotating the cover plate, which is similar to the locking or unlocking achieved by a bayonet lock or a bayonet pin, but the radial flange cannot be rotated below or behind the undercut, so that the flange is fixed to prevent axial pulling out, but instead the cover plate can be rotated over the inserted radial flange, thereby fixing the radial flange to prevent axial pulling out.

[0015] Thus, in one embodiment, the locking or unlocking of containers on a door arrangement can be improved, in particular the operation can be simplified and / or contamination caused by the movement of the containers can be reduced.

[0016] In one embodiment, the first bayonet lock has radial flanges of the lid distributed evenly around its circumference, in one embodiment at least two, preferably at least three, particularly preferably at least four, and in one embodiment up to six. In one embodiment, these radial flanges form the counter-interface of the bayonet lock, and corresponding axial grooves and circumferentially adjacent door undercuts are also distributed to form the interface of the bayonet lock. In one embodiment, the bayonet lock is locked in a known manner. The radial flange of the lid is first inserted (axially) together with the radial flange of the container into the axial groove of the door frame, into the axial groove of the door or the interface of the first bayonet lock, and then rotated circumferentially below or behind the undercut and engaged behind it, thereby securing the lid to the door. By reversing this sequence, in one embodiment, the lid can be released from the door again or the first bayonet lock can be unlocked.

[0017] In one embodiment, the door device, in one embodiment, comprises a one-piece or multi-piece actuator, by means of which the radial flange of the mating interface of the first bayonet lock or the radial flange of the cover in one embodiment is reversibly engaged with the positive shape of the actuator from an inserted position (in which position the radial flange is arranged in an axial groove of the interface) to a locked position, in which position the above-mentioned radial flange engages behind the undercut of the interface, and after corresponding adjustment, the cover is locked to the door, preferably in a rotatable adjustment manner, particularly preferably rotation around one or more axial axes, in one embodiment, the cover plate will also rotate around the axis, in one embodiment, the actuator is (correspondingly) mounted on the door or used (in particular when the door is actuated), or is otherwise arranged and used for this purpose.

[0018] In one embodiment, the actuator has at least one radial flange that engages between adjacent pairs of radial flanges of the cover (in the circumferential direction) for radial flange adjustment of the cover. In one embodiment, the actuator has multiple radial flanges, at least one of which engages between adjacent (different) pairs of radial flanges of the cover (in the circumferential direction).

[0019] Thus, in one embodiment, the first bayonet lock can be locked or unlocked in a particularly advantageous, particularly reliable and / or precise manner.

[0020] In one embodiment, the door arrangement has an actuating device, which in one embodiment is manually (actuated) and / or mechanically and / or mounted on the door frame, in one embodiment is an actuating shaft, and / or in one embodiment is adjustable by means of an actuating device and / or one or more multi-stage gears, wherein the cover plate and / or the actuator are reversibly adjusted by or with the aid of the actuating device and / or gears, in one embodiment positively controlled or in a predetermined sequence, preferably continuously or partially and partially continuously, or an actuating device and / or gears are provided or used for this purpose. In one embodiment, the gearbox has one or more gear (partial) transmissions, one or more cam (partial) transmissions and / or one or more coupling (partial) transmissions, in particular connecting rod (partial) transmissions.

[0021] Thus, in one embodiment, the cover plate and / or the actuator can be operated particularly advantageously, in particular reliably, simply and / or from the container side.

[0022] In one embodiment, the door device has an actuating device, in another embodiment, an electric motor, which is connected to the actuating device and / or the transmission device and reversibly adjusts the cover plate and / or the actuator via the actuating device and / or the transmission device. In one embodiment, the cover plate is adjusted to the locked position via the actuator and / or the transmission device, and the radial flange of the cover is subsequently adjusted to the locked position and / or the radial flange of the cover is adjusted to the insertion position, and the cover plate is subsequently adjusted to the insertion position, or an actuating device provided or used for this purpose.

[0023] Thus, in one embodiment, this facilitates the actuation operation.

[0024] In one embodiment, by or with the aid of an actuating device and / or a gearbox, first, in particular without adjusting the radial flange of the lid, the lid is brought into a locked position for locking the lid to the door, in which case the lid is in the locked position and can lock the container to the door device. Subsequently, in particular under rotation, forced control and / or further actuation of the actuating device and / or gearbox, the radial flange of the lid is adjusted by the actuating device into a locked position for locking the lid to the door. In only one embodiment, the lid does not need to be further adjusted or is at least partially further adjusted, during which the lid continues to block the axial groove to prevent the radial flange from moving outward, and / or, in particular with the reversal of the actuation (direction) of the actuating device and / or gearbox, the radial flange of the lid is first placed by the actuating device in the insertion position or the axial groove at the first bayonet lock interface. Subsequently, in particular under rotation, forced control and / or further actuation of the actuating device and / or gearbox (opposite to the locking direction), preferably without adjusting the radial flange of the lid, the lid is adjusted to the insertion position, or other arrangements or uses are made for this purpose.

[0025] Therefore, in one embodiment, the operation is improved by performing appropriate further actuations in a fixed or structurally predetermined manner, i.e. first the container is secured to the door arrangement and then (if the container is still secured to the door arrangement) the lid is secured to the door, or vice versa, first the lid is unlocked from the door and only then the container is unlocked from the door arrangement.

[0026] In one embodiment, the door arrangement is equipped with a latch that can be driven by an actuator and / or a gearbox, and in one embodiment, the latch reversibly locks the door in its closed position. In one embodiment, the door can be locked in its closed position by a form fit and / or friction fit, or other latches provided or used for this purpose.

[0027] In one embodiment, a door latch comprises a door-side pin and a rotatable rotator mounted on the door frame side. The rotator has an axial groove and a circumferential groove connected thereto. When the pin passes through the rotatable rotator, it can move from the circumferential groove, where it locks the door, to the axial groove of the rotator. When the door is opened, particularly when pivoted, the unlocked door moves from the circumferential groove to the axial groove of the rotator. Vice versa, when closing the door, the pin first enters the axial groove of the rotator and then, by rotating the rotator, enters the circumferential groove of the rotator, thereby locking the door. In one embodiment, such a door latch can be particularly conveniently and / or reliably operated by a single actuator or gear.

[0028] In a preferred embodiment, the lock securing the lid to the door or provided or used for this purpose, in particular a first bayonet lock, should first be locked, and then, in particular by forced control of the actuating device and / or gear and / or, in one embodiment, in particular by rotation, further actuation provided by the actuating device and / or gear box, the latch or the door should be unlocked and / or, in particular with a reversal or reversal of the actuation (direction) of the actuating device and / or gear, first the latch or the door should be locked in its closed position, and subsequently, in particular by forced control of the actuating device and / or gear and / or in one embodiment, in particular by rotation, further actuation provided by the actuating device and / or gear box, the lock securing the lid to the door or provided or used for this purpose, in particular the first bayonet lock, should be unlocked.

[0029] Thus, in one embodiment, this may (further) improve operation and / or reduce the probability of accidentally opening the door, thereby reducing possible contamination of the isolation room.

[0030] In one embodiment, in particular when unlocked and / or forcibly controlled and / or drive is provided by an actuator and / or a gearbox, in one embodiment, by further actuation of the actuator and / or gearbox, in particular rotation, or, if necessary, reversal of the actuation (direction) of the actuator and / or gear, the door will be rotated open, whereas, conversely, the door is first rotated or pivoted to its closed position and then the door device, in particular the actuator and / or gear, will optionally be locked.

[0031] Thus, in one embodiment, the handling can be (further) improved and / or the door can be pivoted from within the receiving space of the container.

[0032] In one embodiment, the gearbox has a (first) freewheel, which can adjust the cover plate when the actuator is adjusted within a first adjustment range, and in one embodiment, the cover plate is not adjusted but blocked when the actuator is adjusted within a second adjustment range and / or when the actuator is adjusted within a third adjustment range, or other arrangements or uses for this purpose.

[0033] In addition, in an alternative embodiment, it is further provided that the gearbox includes a (second) freewheel, which adjusts the actuator when the actuator is adjusted within the adjustment range, and in one embodiment, the freewheel does not adjust the actuator when the actuator is adjusted within the second adjustment range, but blocks it, in one embodiment, the freewheel does not adjust the actuator when the actuator is adjusted within another adjustment range, and in one embodiment, the freewheel blocks the actuator when the actuator is adjusted within the first adjustment range and / or when the actuator is adjusted within the third adjustment range, or other arrangements or uses for this purpose.

[0034] In addition, in an alternative embodiment, it is further provided that the gearbox includes a (third) freewheel, which adjusts the door latch to lock the door when the actuator is within the adjustment range, or in one embodiment, the freewheel will not adjust the door latch but will block it when the actuator is in the third adjustment range, in one embodiment, the freewheel will not adjust the door latch when the actuator is in another adjustment range, and in another embodiment, the freewheel will instead block the door latch when the actuator is adjusted within the first adjustment range and / or when the actuator is adjusted within the second adjustment range, or other arrangements or uses for this purpose.

[0035] Therefore, in particular the following preferred embodiments can be realized:

[0036] In a first adjustment range of the actuating device, the gearbox adjusts only the cover (the first freewheel is locked) without adjusting the actuator and, if applicable, the latch for locking the door, preferably blocking it (the second and, if applicable, the third freewheel are open). In a second adjustment range, the gearbox adjusts only the actuator (the second freewheel is locked) without adjusting the cover and, if applicable, the latch, preferably blocking it (the first and, if applicable, the third freewheel are open). In one embodiment, in a third adjustment range, the gearbox adjusts only the latch (the third freewheel is locked) without adjusting the cover and the actuator, preferably blocking it (the first and second freewheels are open).

[0037] Likewise, in particular the following advantageous embodiments can be realized:

[0038] In a first adjustment range of the actuator, the gearbox adjusts only the cover (the first freewheel is locked), without adjusting the actuator and, if applicable, the latch for locking the door, preferably blocking it (the second and, if applicable, third freewheels are open). In a second adjustment range, the gearbox adjusts the cover—which continues to block the axial groove of the door frame to prevent the radial flange of the container from moving outward—and the actuator (the first and second freewheels are locked), without adjusting the latch, preferably blocking it (the first and, if applicable, third freewheels are open). In one embodiment, in a third adjustment range, the gearbox adjusts only the latch (the third freewheel is locked), without adjusting the cover and the actuator, preferably blocking it (the first and second freewheels are open).

[0039] Thus, in one embodiment, the forced drive sequence described elsewhere can be implemented in a particularly advantageous manner: lock the container to the door via the cover plate; lock the lid to the door using the (first bayonet) lock (if necessary); unlock the latch or door to open the door, and vice versa, close the door to lock the latch or door (if necessary); unlock the lid from the door to unlock the container.

[0040] Generally speaking, the term "forced control" herein should be understood as a specific or fixed sequence or (corresponding) forced control of one or more freewheels in one embodiment. In one embodiment, the freewheel or forced control or guide element comprises one or more connecting rod guides, one or more gears with non-engaging sections, etc. In one embodiment, the gearbox has one or more cam (partial) transmissions, in particular one or more freewheels that can be operated using the cam principle.

[0041] In an alternative embodiment, it is further provided that the gearbox includes a clutch, in one embodiment, the clutch is in a closed state in the closed position of the door and in an open state in the open position of the door. In one embodiment, the clutch is closed by closing the door or opened by opening the door.

[0042] Thus, in one embodiment, this allows the door-side gearbox component to pivot with the door.

[0043] In one embodiment, the cover plate has a ring with multiple grooves, by means of which the radial flange of the container can be inserted into the axial groove of the door frame in the inserted position of the cover plate, or other designs or uses for this purpose.

[0044] Thus, in one embodiment, the insertion of the radial flange of the container and / or the locking of the axial groove and / or the adjustment of the cover plate can be improved.

[0045] In one embodiment, a bayonet lock is provided, by which the lid is reversibly or non-destructively detachably or temporarily fixed to the container, or other settings or uses for this purpose, which bayonet lock is referred to as a second bayonet lock in the present case, but without limiting the general definition of the term, in one embodiment, by closing the first bayonet lock, in one embodiment, by adjusting the radial flange of the lid to its locking position, in one embodiment, the above situations occur simultaneously, which unlocks the second bayonet lock, or other settings or uses for this purpose.

[0046] Therefore, the operation may be further improved in one embodiment.

[0047] According to one embodiment of the invention, in order to connect a container to an isolation chamber via the door device described herein, the radial flange of the container is axially inserted into the axial groove of the door frame and brought into a locked position by adjusting the cover plate, in one embodiment, by an actuating drive, in particular within its first adjustment range, and / or by a gearbox (driven by the actuating device in one embodiment).

[0048] In one embodiment, the actuator for adjusting the radial flange of the lid is subsequently adjusted into a locked position, preferably by positive control, in order to secure the lid to the door and, in a preferred embodiment, also to unlock the second bayonet lock, i.e., to transfer the lid from the container to the door. In one embodiment, the actuator is (correspondingly) adjusted by the actuating device, in particular within its second adjustment range, and / or by a gearbox (in one embodiment driven by the actuating device).

[0049] In one embodiment, after adjustment of the actuator, the latch or door is unlocked, preferably by positive control, in one embodiment driven by the actuator, in particular within its third adjustment range, and / or by (in one embodiment driven by) a gearbox.

[0050] In one embodiment, a door with a lid, in particular a pivoting door, can be adjusted by being driven from the side of the container or the container receiving area out of and / or into the insulating space. The goods to be transported can then be removed from the container (interior) or its transport space and / or introduced into the container or the transport space.

[0051] To remove a container connected to the isolation chamber or door device, in one embodiment, the corresponding adjustment steps of the door, latch (if applicable), actuator (if applicable), cover (if applicable) and / or actuating device (if applicable) and / or gear box (if applicable) are performed in the reverse order and / or reverse direction.

[0052] In one embodiment, the door means delimits the isolation chamber. In one embodiment, the door means is attached to a wall of the isolation chamber, or an opening thereof forms a passage into the isolation chamber, or the door means is provided or used for this purpose.

[0053] If a second or third element is mentioned, eg a second bayonet lock or a third adjustment range, this does not necessarily mean that a (corresponding) first or second element, eg a first bayonet lock or a second adjustment range, is present.

[0054] In one embodiment, the actuation is manual actuation, in particular by manually applying an actuating force or an actuating torque.

[0055] Thus, in one embodiment, this may improve handling, particularly flexible and / or aseptic handling.

[0056] In one embodiment, the actuation is by drive or electric actuation, in particular electric actuation.

[0057] Therefore, in one embodiment, operation can be performed more easily.

[0058] In one embodiment, the actuating device is mounted on a side of the door device facing away from or opposite to the isolation chamber, or on the container side, or in the receiving space of the container.

[0059] Thus, in one embodiment, this may improve handling, particularly aseptic handling. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Figure 1-5 A door assembly system employed during a method of connecting a container 20 to an isolation chamber 100 according to one embodiment of the present invention is shown, each in an axial half-section (vertical upper half-section) and a bottom plan view.

[0070] In the first step (see Figure 1 ), the radial flange 21 of the container flange 22 of the container 20 is inserted into the axial groove 11 of the door frame 10 of the door device.

[0071] During this process, the door 12 of the door arrangement is locked by the door latch 5 in the closed position, in which position it closes the passage opening 13 of the door arrangement or door frame (see Figure 5 ).

[0072] The lid 30 is reversibly connected to the container 20 by means of a second bayonet lock 31 and closes the inlet and outlet openings 23 of the container (see Figure 5 ). A mating interface with a first bayonet lock in the shape of a mostly radial flange 32 .

[0073] When the radial flanges 21 of the container 20 are axially inserted into the axial grooves 11 on the door frame side, these radial flanges 32 are axially inserted into the axial grooves 14 of the door-side interface of the first bayonet lock.

[0074] Figure 2 The radial flanges 21 , 32 are shown in their position after being inserted into the axial grooves 11 , 14 .

[0075] Starting from this insertion position, by rotating the actuator 40, which then drives or adjusts the gear box 41, the cover plate 15 first starts from the insertion position, in which the axial groove 11 is released for inserting and removing the radial flange 21, by the overlap of the groove 15a of the annular cover plate 15 with the axial groove 11 of the door frame 10, or by releasing it to Figure 3 The locked position shown in FIG. 1 is a position in which the cover plate blocks the axial groove 11 to prevent the radial flange 21 from moving outwards, thereby locking the container 20 on the door device (see FIG. Figure 2 Figure 3 The actuator 40 can be moved from the container 20's accommodation space or the container side ( Figure 2 The gearbox 41 is rotated in one embodiment by manual rotation and in another embodiment by a drive device (not shown), but can also be connected to the gear box 41 for operation elsewhere.

[0076] After the first adjustment range of the actuator 40 , when the actuator 40 continues to rotate in the same direction, the first free wheel 42 (previously locked) blocks the cover instead of performing further adjustment, or the first free wheel 42 is opened.

[0077] The door-side actuator 6 has four radial flanges 6a, each of which engages between a different pair of adjacent radial flanges 32 of the cover.

[0078] When the actuator 40 is rotated further, the second free wheel 43 (previously open) is locked, and therefore the actuator 40 or the gear box 41 will rotate the previously locked actuator 6 (see Figure 3 Figure 4 ).

[0079] Thus, the actuator 6 or its radial flange 6a moves the radial flange 32 of the cover from the insertion position ( Figure 1-3 ) begins adjustment, the radial flange being originally arranged in the axial groove 14 of the first bayonet lock interface, until it enters the locking position ( Figure 4 、 5 ), these radial flanges 32 engage behind the undercut 16 of the door-side interface, thereby locking the cover 30 to the door 12.

[0080] The rotation of the cover 30 and its radial flange 32 also simultaneously unlocks the second bayonet lock 31 .

[0081] After the second adjustment range of the actuator 40 , when the actuator 40 is further rotated in the same direction, the second free wheel 43 blocks the actuator instead of performing further adjustment, or the second free wheel 43 is opened.

[0082] Since the third freewheel 44 is now locked (previously opened), the actuator 40 or the gearbox 41 now unlocks the latch 5, whereupon the door 12 with the cover 30 is opened, whereby also the freewheel 45 of the gearbox is opened (see Figure 4 Figure 5 ).

[0083] In one embodiment, such pivoting opening of the door 12 may be achieved by further rotation of the actuating device 40 in the same direction and / or by action of the gear box 41 .

[0084] The above sequence is reversed by rotating the actuator 40 in the opposite direction and after closing the door (if necessary with the aid of the actuator 40 and / or the gear box 41), the door is locked by the latch 5 (see Figure 5 Figure 4 ), then by unlocking the first bayonet lock, ie unscrewing the radial flange 32 under the undercut 16, the lid is unlocked from the door and at the same time by locking the second bayonet lock 31, the lid is locked on the container (see Figure 4 Figure 3 ), then by rotating the cover 15 (see Figure 3 Figure 2 ), releasing the axial groove 11 so that the container 20 with the lid 30 can be removed (see Figure 2 Figure 1 ).

[0085] Figure 6 In particular, a door-side pin 51 and a rotatable rotator 52 mounted on a door frame-side latch are shown, whereby the pin 51 can be fixed or released by rotating the rotator 52 .

[0086] Figure 7 and Figure 8 In particular, an actuator 40 is shown, which can be actuated from the container's receiving space or from the container side ( Figure 1 top) actuation.

[0087] Although exemplary embodiments have been described in detail in the foregoing specification, it should be noted that significant variations may exist.

[0088] Thus, for example, the cover plate 15 can be rotated further within the second adjustment range, i.e. when the actuator 6 is adjusted to lock the first bayonet lock, while simultaneously continuing to block the axial groove 11 to prevent an outward movement of the radial flange 21, and can only be blocked by the first free wheel 42 together with the second free wheel 43 or before or after this before the third free wheel 44 adjusts the latch 5 or the actuator 40 is adjusted within the third adjustment range.

[0089] also, Figures 1 to 5 should be understood as a functional diagram. For example, Figure 6 The latch 5 is shown to have a pin 51 for securing the door engaged in a circumferential groove of a rotating body 52 mounted on the side of the door frame in order to lock the latch. The rotating body 52 can be rotated by an actuating device or a gear box to move the pin out of the circumferential groove into an axial groove, from which the pin can be moved when the door is pivoted open.

[0090] Furthermore, it should be noted that the exemplary embodiments are merely examples and are not intended to limit the scope of protection, application, or structure in any way. On the contrary, the above description provides a guide for those skilled in the art to at least one exemplary embodiment, from which various modifications may be made, particularly with respect to the function and arrangement of the described components, without departing from the scope of protection resulting from the claims and the equivalent combinations of these features.
