[0002] From EP 1 440 448 B1, a door device with a double bayonet closure composed of two bayonet closures of different chirality is known, wherein the container is locked or unlocked on a door frame by turning handles attached to a container flange.

[0003] US 2016 / 201382 A1 relates to a device for the sealed connection between a first and a second closed space, wherein the closed spaces each comprise a flange and the first door tightly closes an opening delimited by the flange, wherein the connecting device comprises: a first part for fastening the flanges, a second part for tightly fastening the doors and for detaching one of the doors from its flange, a third part for detaching the other door with respect to its flange, a fourth part for opening a passage between the first and the second closed space, wherein the device also comprises means for locking the second securing means, which prevents the separation of the doors as long as the connection between the two closed spaces is effective, wherein the locking means is automatically activated by the actuation of the second securing means.

[0004] The object of the present invention is to improve the connection of a container to an insulation room.

[0005] This object is achieved by a door device having the features of claim 1. Claims 7 and 10 protect a system with a door device described herein, and a method for connecting a container described herein to the isolation chamber by means of a connection described herein. The subclaims relate to advantageous developments.

[0006] The invention is described in the appended set of claims.

[0007] According to the present invention, a door device which is designed or used for the preferably sealing, particularly preferably sterile and / or airtight and / or watertight, connection of a container to an isolation chamber comprises a frame, in one embodiment made up of several parts, which in one embodiment also delimits the isolation chamber or is designed or used for this purpose, and a door which is reversibly adjustable, preferably pivotable, particularly preferably horizontally pivotable, from a closed position in which it closes a through opening in the door device or frame to an open position in which it releases this through opening. The door is mounted, preferably pivotable, on the frame.

[0008] In this way, an advantageous, in particular compact, simple and / or reliable, opening and closing kinematics can be realized in one embodiment.

[0009] According to the present invention, a container to be connected, in particular temporarily or non-destructively detachably connected, has a container flange with a plurality of, in one embodiment at least two, preferably at least three, particularly preferably at least four, in one embodiment a maximum of six, radial flanges distributed evenly over its circumference, in one embodiment radial outer flanges or radial flanges extending radially outwards (away) from the container flange, as well as a lid for closing an inlet and / or outlet opening of the container, which lid is fastened to the container in a manner that can be fastened, in particular temporarily or non-destructively detachably, or is configured or used for this purpose. In one embodiment, the container interior with the attached lid forms a hermetically sealed, in one embodiment sterile, transport space, in particular for medical instruments, small parts or the like.In one embodiment, the inlet and / or outlet opening of the container connected to the door device and the through-opening of the door device overlap each other at least partially in order to move transported goods out of or into the container through these openings.

[0010] In one embodiment, the container can be connected in such a way that the contents of the container can be moved into the isolation room, which is separated from a living area or outside the container, or from this into the container while maintaining sterility.

[0011] According to the present invention, the door has an interface and, in one embodiment, the cover has a counter-interface of a closure, in a preferred embodiment a bayonet closure, which is referred to herein without restriction of generality as the first bayonet closure, by means of which the cover can be fastened to the door, in particular temporarily or non-destructively detachable, or which is designed or used for this purpose.

[0012] In one embodiment, the lid can be transferred from the container to the door and moved through or together with the door to open or close the inlet and / or outlet opening of the container connected to the door device. In particular, by operating the door, in one embodiment from the container's storage area or from the container side, the lid can be handled advantageously, preferably in a sterile manner.

[0013] A bayonet lock is particularly suitable for this purpose due to its reliability and kinematics.

[0014] According to the present invention, the frame has a plurality of axial grooves, in one embodiment corresponding to at least two, preferably at least three, in particular at least four, in one embodiment a maximum of six, into which the radial flanges of the container can be inserted (axially), in one embodiment in a form-fitting manner (guided), in particular temporarily or non-destructively detachable, are or are inserted (axially) or which are designed or used for this purpose.

[0015] In one embodiment, "axial" refers to an insertion or longitudinal direction of the axial grooves and / or to a preferably common axis of rotation of the cover explained below and / or the actuator explained below, "circumferential direction" refers to a direction of rotation about an axial (longitudinal) axis, in one embodiment the axis of symmetry of the container flange, or the axis of rotation, "radial" refers to a direction perpendicular to the axial and circumferential directions.

[0016] According to the present invention, the door device comprises a single- or multi-part cover which is reversibly adjustable, preferably rotatable, particularly preferably rotatable about an axial axis or the rotation axis, from an insertion position, in which it exposes the axial grooves for inserting and removing the radial flanges, to a locking position. In the locking position, the cover blocks the axial grooves against removal of the radial flanges, in one embodiment by positive and / or frictional engagement, in order to lock the container to the door device. In one embodiment, the cover is mounted on the frame in a correspondingly adjustable, in particular rotatable, manner.

[0017] Thus, in one embodiment, the bayonet closure of the aforementioned EP 1 440 448 B1, which requires a rotation of the container for locking or unlocking, is replaced by a rotation of the cover, which realizes a locking or unlocking analogously to a bayonet closure, but in which radial flanges are not rotated under or behind undercuts and thereby secured against axial withdrawal, but conversely the cover is rotated over the inserted radial flanges and thereby secures them against axial withdrawal.

[0018] In one embodiment, this can improve locking and unlocking of the container on the door device, in particular simplify handling and / or reduce contamination due to the movement of the container.

[0019] In one embodiment, the first bayonet closure has a plurality of, in one embodiment at least two, preferably at least three, particularly preferably at least four, in one embodiment at most six, radial flanges of the lid which are distributed evenly over its circumference and in one embodiment can form a counter-interface of this bayonet closure, and corresponding axial grooves and circumferentially adjacent undercuts of the door which can form the interface of this bayonet closure, wherein in one embodiment for locking the bayonet closure in a manner known per se the radial flanges of the lid are first inserted (axially) into the axial grooves of the door or interface of the first bayonet closure, in one embodiment together with an (axial) insertion of the radial flanges of the container into the axial grooves of the frame, and then inserted in the circumferential direction under or above.can be turned behind the undercuts to engage behind them and thus secure the cover to the door. By reversing this sequence, the cover can be removed from the door or the first bayonet lock can be unlocked.

[0020] In one embodiment, the door device, in one embodiment the door, has a one-part or multi-part actuator (by means of which) the radial flanges of the counter-interface of the first bayonet closure or of the cover are reversibly adjusted, in one embodiment with positive engagement with the actuator, from an insertion position in which they are arranged in (the) axial grooves of the interface, into a locking position in which these radial flanges engage behind undercuts of the interface in order to lock the cover to the door, preferably rotated, particularly preferably about an or the axial axis around which, in one embodiment, the cover is also rotated, rotated, or which is set up for this purpose, in one embodiment (correspondingly) mounted on the door, is or is used, in particular actuated.

[0021] In one embodiment, the actuator has at least one radial flange which engages between a pair of (circumferentially) adjacent radial flanges of the cover for or during this adjustment of the radial flanges of the cover, in one embodiment several radial flanges, wherein at least one of these radial flanges of the actuator engages between a (different) pair of (circumferentially) adjacent radial flanges of the cover.

[0022] In one embodiment, the first bayonet lock can thereby be locked or unlocked particularly advantageously, in particular reliably and / or precisely.

[0023] In one embodiment, the door device has an input drive, in one embodiment manually (operable) and / or mechanical and / or arranged on the frame, in one embodiment an input shaft, and / or a gear, in one embodiment adjustable by the input drive and / or single- or multi-stage, wherein the cover and / or the actuator are adjusted by or by means of the input drive and / or gear reversibly, in one embodiment positively controlled or in a structurally predetermined sequence, preferably sequentially or partly together and partly sequentially, or the input drive and / or gear are configured or used for this purpose. In one embodiment, the gear has one or more gear (partial) transmissions, one or more cam (partial) transmissions, and / or one or more coupling (partial) transmissions, in particular coupling rod (partial) transmissions.

[0024] In one embodiment, the cover and / or actuator can thereby be actuated particularly advantageously, in particular reliably, simply and / or from the container side.

[0025] In one embodiment, the door device has a drive, in a further development with an electric motor, which is coupled to the input drive and / or to the gear and reversibly adjusts the cover and / or the actuator via the input drive and / or gear, in one embodiment by means of the actuator and / or gear the cover is adjusted into a locking position and subsequently the radial flanges of the cover into a locking position and / or the radial flanges of the cover into an insertion position and subsequently the cover into an insertion position, or is set up for this purpose or is used for this purpose.

[0026] This can make operation easier in one version.

[0027] In one embodiment, by means of or by means of an input drive and / or gear, the cover is first moved into a locking position for locking the container to the door device, in particular without adjusting the radial flanges of the cover into a locking position for locking the cover to the door, and then, in particular in a positively controlled manner and / or upon further actuation, in particular rotation, of the input drive and / or gear, the radial flanges of the cover are adjusted by means of the actuator into a locking position for locking the cover to the door, in one embodiment alone without further adjustment of the cover or at least partially with further adjustment of the cover, which in the process continues to block the axial grooves against the radial flanges being pulled out, and / or, in particular upon or with reversal of the actuation (direction) of the input drive and / or gear, the radial flanges of the cover are first moved into an insertion position orthe axial grooves of the interface of the first bayonet lock and subsequently, in particular in a positively controlled manner and / or upon further actuation (in the opposite direction for locking), in particular rotation, of the input drive and / or gear, the cover, preferably without adjusting the radial flanges of the cover, is adjusted into an insertion position or the input drive and / or gear are designed or used for this purpose.

[0028] In one embodiment, handling can be improved by further actuating the container in a fixed or structurally predetermined manner, firstly fastening the container to the door device and then (with the container still attached to the door device) the lid to the door, or conversely, first unlocking the lid from the door and only then unlocking the container from the door device.

[0029] In one embodiment, the door device has a bolt which can be actuated by the drive and / or the gear, in one embodiment, and which locks the door in its closed position reversibly, in one embodiment positively and / or frictionally, or is designed or used for this purpose.

[0030] In one embodiment, this latch has a pin on the door side and a rotating body rotatably mounted on the frame side with an axial groove and a circumferential groove connected to it, wherein the pin can be extended by rotating the rotating body from its circumferential groove, in which it locks the door, into the axial groove of the rotating body and from there, opening, in particular pivoting, the door unlocked by the transfer from the circumferential to the axial groove of the rotating body or, conversely, when the door is closed, first into the axial groove of the rotating body and from there, by rotating the rotating body, continues into the circumferential groove of the rotating body, thereby locking the door. In one embodiment, such a latch can be operated particularly easily and / or reliably by means of a drive or a gear.

[0031] In a preferred embodiment, first the lock which fastens the cover to the door or is designed or used for this purpose, in particular the first bayonet lock, is locked and then, in particular in a positively controlled manner and / or by the input drive and / or the gear, in one embodiment by further actuation, in particular rotation, of the input drive and / or gear, this bolt or the door is unlocked and / or, in particular when or by reversing the actuation (direction) of the input drive and / or gear, conversely, first this bolt or the door is locked in its closed position and then, in particular in a positively controlled manner and / or by the input drive and / or the gear, in one embodiment by further actuation, in particular rotation, of the input drive and / or gear, the lock which fastens the cover to the door or is designed or used for this purpose, in particular the first bayonet lock, is unlocked orthe bolt is set up or used for this purpose.

[0032] In one embodiment, this can (further) improve handling and / or reduce the probability of unintentional opening of the door and thus possible contamination of the isolation room.

[0033] In one embodiment, the door is swung open, in particular after unlocking and / or positively controlled and / or by the drive and / or the gear, in one embodiment by further actuation, in particular rotation, of the drive and / or gear, or, if appropriate by reversing the actuation (direction) of the drive and / or gear, conversely, the door is first swung or pivoted into its closed position and then optionally locked, or the door device, in particular the drive and / or gear, is set up or used for this purpose.

[0034] In one embodiment, this allows handling to be (further) improved and / or the door to be pivoted from the container's area.

[0035] In one embodiment, the gearbox has a (first) freewheel which adjusts the cover when or while the input is adjusted in a first adjustment range and does not adjust the cover, in one embodiment instead blocks it when or while the input is adjusted in a second adjustment range and / or when or while the input is adjusted in a third adjustment range, or which is configured or used for this purpose.

[0036] Additionally or alternatively, in one embodiment, the transmission has a (second) freewheel which adjusts the actuator when or while the input is adjusted in an adjustment range, which in one embodiment is the second adjustment range, and does not adjust the actuator, in one embodiment instead blocks it when or while the input is adjusted in another adjustment range, in one embodiment does not adjust it, in one embodiment instead blocks it when or while the input is adjusted in the first adjustment range and / or when or while the input is adjusted in the third adjustment range, or which is set up or used for this purpose.

[0037] Additionally or alternatively, in one embodiment, the gear has a (third) freewheel which adjusts the bolt to lock the door when or while the drive is adjusted in an adjustment range, which in one embodiment is the third adjustment range, and does not adjust the bolt, in one embodiment instead blocks it when or while the drive is adjusted in another adjustment range, in one embodiment does not adjust it, in one embodiment instead blocks it when or while the drive is adjusted in the first adjustment range and / or when or while the drive is adjusted in the second adjustment range, or which is set up or used for this purpose.

[0038] Thus, in particular, the following preferred embodiment can be realized: In a first adjustment range of the input drive, the gear only adjusts the cover (first freewheel locks), while it does not adjust, preferably blocks, the actuator and, if applicable, the bolt for locking the door (second freewheel and, if applicable, third freewheel open). In a second adjustment range, the gear then only adjusts the actuator (second freewheel locks), while it does not adjust, preferably blocks, the cover and, if applicable, the bolt (first freewheel and, if applicable, third freewheel open). In one embodiment, in a third adjustment range, the gear only adjusts the bolt (third freewheel locks), while it does not adjust, preferably blocks, the cover and the actuator (first and second freewheel open).

[0039] Likewise, the following advantageous embodiment can be realized: In a first adjustment range of the input drive, the gear only adjusts the cover (first freewheel locks), while it does not adjust the actuator and, if applicable, the latch for locking the door, preferably blocking it (second freewheel and, if applicable, third freewheel open). In a second adjustment range, the gear then adjusts both the cover, which continues to block the axial grooves of the frame against the radial flanges of the container from extending, and the actuator (first and second freewheel locks), while it does not adjust the latch, if applicable, preferably blocking it (third freewheel open). In one embodiment, in a third adjustment range, the gear only adjusts the latch (third freewheel locks), while it does not adjust the cover and the actuator, preferably blocking it (first and second freewheel open).

[0040] In this way, in one embodiment, the positively guided sequence explained elsewhere: locking the container to the door device by means of a cover → locking the lid to the door by means of a (first bayonet) lock and if necessary → unlocking the bolt or the door → opening the door or vice versa closing the door → if necessary locking the bolt or the door → unlocking the lid from the door → unlocking the container can be implemented particularly advantageously.

[0041] In general, the term "forced control" referred to here refers in particular to a structurally predefined or fixed sequence or (corresponding) forced guidance, in one embodiment by one or more freewheels. A freewheel or such a forced control or guidance comprises, in one embodiment, one or more slotted guides, one or more gearings with non-engaging sections, or the like. In one embodiment, the transmission has one or more cam disk (sub-)transmissions; in particular, one or more freewheels can be implemented using the cam disk principle.

[0042] Additionally or alternatively, in one embodiment, the transmission has a clutch which is closed in the closed position of the door and opened in the open position of the door, in one embodiment is closed by closing the door or opened by opening the door.

[0043] In one version, a gear part on the door side can pivot with the door.

[0044] In one embodiment, the cover has a ring with a plurality of grooves through which, in the insertion position of the cover, the radial flanges of the container can be inserted or are inserted into the axial grooves of the frame or which are designed or used for this purpose.

[0045] In one embodiment, this can improve the insertion of the radial flanges of the container and / or the locking of the axial grooves and / or the adjustment of the cover.

[0046] In one embodiment, a bayonet closure is provided by which the lid is or is reversibly or non-destructively detachable or temporarily attached to the container or which is or is used for this purpose, wherein this bayonet closure is referred to here without restriction of generality as a second bayonet closure and is unlocked in one embodiment by closing the first bayonet closure, in one embodiment by adjusting the radial flanges of the lid into their locking position, in one embodiment simultaneously, or is or is used for this purpose.

[0047] This allows handling to be further improved in one version.

[0048] According to one embodiment of the present invention, in order to connect a container described here to an insulation space by means of a door device described here, the radial flanges of the container are inserted axially into the axial grooves of the frame and locked there by adjusting the cover into a locking position, in one embodiment by actuating the input drive, in particular in its first adjustment range, and / or by means of the gear (actuated by the input drive in one embodiment).

[0049] In one embodiment, the actuator for adjusting the radial flanges of the lid is subsequently adjusted, preferably under positive control, into a locking position 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 adjusted (correspondingly) by actuating the input drive, in particular in its second adjustment range, and / or by means of the gear (actuated by the input drive in one embodiment).

[0050] In one embodiment, following this adjustment of the actuator, the bolt or the door is unlocked, preferably in a positively controlled manner, in one embodiment by actuating the input drive, in particular its third adjustment range, and / or by means of the gear (actuated by the input drive in one embodiment).

[0051] In one embodiment, the door with the attached lid is moved, in particular pivoted, from the container side or a storage area of the container out of and / or into the isolation chamber. Transport goods can then be removed from the container (inside) or its transport area and / or inserted into it.

[0052] To remove the container connected to the isolation room or the door device, the corresponding steps are carried out in reverse order and / or by adjusting the door, if applicable the latch, if applicable the actuator, the cover and / or if applicable the drive and / or gear in the opposite direction.

[0053] In one embodiment, the door device delimits the isolation room, in one embodiment is attached to a wall of the isolation room, or its through opening forms an access to the isolation room or the door device is designed or used for this purpose.

[0054] If reference is made here to a second or third element, for example the second bayonet closure or third adjustment range, this does not necessarily imply the presence of a (corresponding) first or second element, for example the first bayonet closure or second adjustment range.

[0055] In one embodiment, actuation is manual actuation, in particular (by) manually applying an actuating force or an actuating torque.

[0056] In one embodiment, this can improve handling, particularly variable and / or sterile handling.

[0057] In one embodiment, actuation is actuation by a drive or motor actuation, in particular electric motor actuation.

[0058] This can make handling easier in one version.

[0059] In one embodiment, the drive is arranged on a side of the door device facing away from or opposite the insulation space or on a container side or in a living space of the container.

[0060] In one embodiment, this can improve handling, particularly sterile handling.

[0061] Further advantages and features emerge from the subclaims and the exemplary embodiments. The following shows, partially schematically: Fig. 1: a system with a door device when connecting a container according to an embodiment of the present invention; Fig. 2: the system with axially inserted radial flanges of the container; Fig. 3: the system with the cover of the door device adjusted; Fig. 4: the system with the actuator adjusted; and Fig. 5: the system with the door open; Fig. 6: a plan view of the door device with the door open, seen from the isolation space; Fig. 7: a perspective view of the door device with the door closed, seen from the living space of the container; and Fig. 8: an exploded view of components of the door device.

[0062] Fig. 1-5 show a functional representation of a system with a door device during a method for connecting a container 20 to an insulation space 100 according to an embodiment of the present invention, each at the top in a half-section along an axial direction (vertical in the upper half-section) and below in a plan view.

[0063] In a first step (cf. Fig. 1 ) radial flanges 21 of a container flange 22 of the container 20 are inserted into axial grooves 11 of a frame 10 of the door device.

[0064] A door 12 of the door device is locked by a bolt 5 in a closed position, in which it forms a passage opening 13 of the door device or the frame (cf. Fig. 5 ) closes.

[0065] A lid 30 is reversibly attached to the container 20 by a second bayonet closure 31 and closes an inlet and outlet opening 23 (cf. Fig. 5 ) of the container. It has a counter interface of a first bayonet closure in the form of several radial flanges 32.

[0066] These radial flanges 32 are axially inserted into axial grooves 14 of a door-side interface of the first bayonet lock during axial insertion of the radial flanges 21 of the container 20 into the frame-side axial grooves 11.

[0067] Fig. 2 shows the position after inserting the radial flanges 21, 32 into the axial grooves 11, 14.

[0068] Starting from this insertion position, by rotating an input drive 40, which actuates or adjusts a gear 41, a cover 15 is first moved from the insertion position in which it releases the axial grooves 11 for the insertion and removal of the radial flanges 21, by grooves 15a of the annular cover 15 overlapping or leaving free these axial grooves 11 of the frame 10, into a Fig. 3 shown locking position, in which it blocks the axial grooves 11 against the radial flanges 21 being extended in order to lock the container 20 to the door device (cf. Fig. 2 → Fig. 3 ). The drive 40 can be operated from a room in the container 20 or from a container side (top in Fig. 2 ) can be rotated, in one version manually, in another version by a drive (not shown), which can, however, also be coupled to the gear 41 at another point.

[0069] Following this first adjustment range of the input drive 40, a (previously locking) first freewheel 42 blocks the cover when the input drive 40 continues to rotate in the same direction, instead of adjusting it further, or this first freewheel 42 opens it.

[0070] A door-side actuator 6 has four radial flanges 6a, each of which engages between another pair of adjacent radial flanges 32 of the cover.

[0071] During this further rotation of the input drive 40, a (previously open) second freewheel 43 locks, so that the input drive 40 or gear 41 now rotates this previously blocked actuator 6 (cf. Fig. 3 → Fig. 4 ).

[0072] As a result, the actuator 6 or its radial flanges 6a adjust these radial flanges 32 of the cover from an insertion position ( Fig. 1-3 ), in which they are arranged in the axial grooves 14 of the interface of the first bayonet lock, into a locking position ( Fig. 4 , 5 ), in which these radial flanges 32 engage undercuts 16 of the door-side interface in order to lock the cover 30 to the door 12.

[0073] By rotating the cover 30 with its radial flanges 32, the second bayonet lock 31 is simultaneously unlocked.

[0074] Following this second adjustment range of the input drive 40, the second freewheel 43 blocks the actuator when the input drive 40 continues to rotate in the same direction, instead of adjusting it further, or the second freewheel 43 opens it.

[0075] Now a (previously open) third freewheel 44 locks, so that the input drive 40 or gear 41 can unlock the bolt 5 and the door 12 with the cover 30 attached to it can be opened, whereby a clutch 45 of the gear opens (cf. Fig. 4 → Fig. 5 ).

[0076] In one embodiment, this pivoting of the door 12 can be effected or carried out by further rotating the input drive 40 in the same direction and / or by means of the gear 41.

[0077] By reversing the above-mentioned sequence by turning the drive 40 in the opposite direction, after closing the door (if necessary by means of the drive 40 and / or gear 41), the door is locked by the bolt 5 (cf. Fig. 5 → Fig. 4 ), then the lid is released from the door by unlocking the first bayonet catch, ie unscrewing the radial flanges 32 under the undercuts 16, and at the same time locked to the container by locking the second bayonet catch 31 (cf. Fig. 4 → Fig. 3 ), and then by turning the cover 15 the axial grooves 11 are released (cf. Fig. 3 → Fig. 2 ), so that the container 20 with the lid 30 attached to it can be removed (cf. Fig. 2 → Fig. 1 ).

[0078] Fig. 6 illustrates in particular a door-side pin 51 and a frame-side rotatably mounted rotating body 52 of the bolt, wherein the pin 51 can be locked or released by turning the rotating body 52.

[0079] Fig. 7 , 8 illustrate in particular an input drive 40, which is connected from a living space of the container or a container side (top in Fig. 1 ) can be operated.

[0080] Although exemplary embodiments have been explained in the preceding description, it should be noted that a large number of modifications are possible.

[0081] For example, the cover 15 can also be rotated further in the second adjustment range, ie when adjusting the actuator 6 to lock the first bayonet lock, and in the process continue to block the axial grooves 11 against the radial flanges 21 being extended, and can only be blocked by the first freewheel 42, if necessary together with the second freewheel 43 or before or after this, before the third freewheel 44 adjusts the bolt 5 or the input drive 40 is adjusted for this purpose in the third adjustment range.

[0082] In addition, the Fig. 1-5 as a functional representation. For example, the bar 5, as in Fig. 6 recognizable, can also be realized in that a door-fixed pin 51 engages in a circumferential groove of a rotating body 52 mounted on the frame side in order to lock the door, wherein this rotating body 52 can be rotated by means of an input drive or gear so that the pin moves from the circumferential groove into an axial groove from which it can move out when the door is pivoted open.

[0083] Furthermore, it should be noted that the exemplary embodiments are merely examples and are not intended to limit the scope of protection, applications, or structure in any way. Rather, the preceding description provides the skilled person with a guide for implementing at least one exemplary embodiment. Various modifications, particularly with regard to the function and arrangement of the described components, may be made without departing from the scope of protection as defined by the claims and equivalent combinations of features.
