Description

[0001] The present invention relates to a wall mount for an emergency ventilator arrangement according to the preamble of claim 1.

[0002] Such a wall mount is known from US 2010 / 0219220 A1.

[0003] Another wall mount is known from DE 10 2007 016 410 A1, in particular from its figures 6 and 8.

[0004] For a wall mount, it is important to ensure the safe deployment of the emergency ventilator setup while also allowing for easy release in an emergency. The wall mounts described in US 2010 / 0219220 A1 and DE 10 2007 016 410 A1 can be operated with one hand.

[0005] The mounting bracket of US 2010 / 0219220 A1 is integrated into a seat. A pivoting locking hood secures the ventilator to the bracket via a latch, creating a positive locking mechanism. The locking hood, pre-tensioned to its release position by a spring, pivots into its release position after a rigidly connected retaining pin is unlocked by actuating the latch via a Bowden cable, allowing removal of the ventilator.

[0006] The mounting structure of the wall bracket of DE 10 2007 016 410 A1 is formed by a mounting groove. The locking structure of the wall bracket known from DE 10 2007 016 410 A1 comprises a latch that can be moved translationally, presumably against spring tension. The movable latch has an insertion ramp on its side facing away from the base structure, against which a section of the emergency ventilator assembly can be positioned. As the emergency ventilator assembly approaches the base structure, this section can move the latch translationally until an engagement recess on the emergency ventilator assembly aligns with the latch due to the movement of the emergency ventilator assembly towards the base structure, and the latch can then engage in the recess.Then, in the engagement position, the trap engages a section of the emergency ventilator assembly located between the engagement recess and the base structure as the locking counter-structure.

[0007] The trap can be released from the engagement recess by two coaxial actuating rods, each projecting orthogonally to the displacement axis of the trap in opposite directions, thereby releasing the emergency ventilator arrangement.

[0008] When the emergency ventilator assembly is removed from the wall bracket, the latch is in the same position as when the latch is locked to the wall bracket, i.e., in the engagement position. Therefore, when attaching the emergency ventilator assembly to the wall bracket, the full holding force of the latch must be overcome to engage the latch in the engagement recess on the emergency ventilator assembly.

[0009] Another wall bracket for an emergency ventilator assembly is known from DE 10 2012 005 668 A1. In this known wall bracket, the complex locking device comprises locking bolts that can be moved by Bowden cables. These bolts engage locking projections on a support frame of the emergency ventilator assembly with spring bias and release them again when the Bowden cables are actuated.

[0010] Finally, a wall bracket is known from WO 2020 / 136271 A1, specifically from Figure 58, which carries different devices and in which an emergency ventilator arrangement can be suspended in an unspecified manner from the underside of a mounting plate projecting horizontally from a vertical base structure.

[0011] The object of the present invention is to improve the aforementioned wall bracket in such a way that an emergency ventilator arrangement can be attached to it with as little effort as possible and yet as securely as possible until the next removal.

[0012] The present invention solves this problem by means of a wall bracket having all the features of claim 1.

[0013] In the wall bracket known from DE 10 2007 016 410 A1, the preparation position and the engagement position are identical. As explained above, when the emergency ventilator assembly engages with the known locking device, the latch must be retracted as far as possible, either by the emergency ventilator assembly itself or by manually operating the described actuating rods, in order to engage the engagement recess after it has been aligned.

[0014] Since the preparation position for intervention in the wall bracket presented here differs from the subsequent intervention position, in which the locking device holds the emergency ventilator assembly to the wall bracket, the locking structure does not first need to be moved from the intervention position to an insertion position, which allows the insertion of the locking counterpart into its position to be secured, and then back from this insertion position to the intervention position. Because the preparation position differs from the intervention position, the path of the locking structure into the intervention position can be shortened.This also reduces the force and shortens the time required to move the locking structure from the intervention preparation position to a position in which the locking counter-structure of the emergency ventilator assembly can be brought close enough to the base structure that it can be secured against removal from the base structure by the locking structure, which is subsequently moved into the intervention position, through positive locking. Since the intervention position is independent of the intervention preparation position, the locking security achievable in the intervention position is unaffected by the intervention preparation position. Therefore, the locking security is not reduced by choosing an intervention preparation position that differs from the intervention position.

[0015] In the intervention preparation position, a positive locking mechanism that prevents the emergency ventilator assembly from being removed from the wall bracket is preferably not possible.

[0016] According to a preferred embodiment, the removal of an emergency ventilator assembly from the wall mount without loss of locking security during the mounting of the emergency ventilator assembly on the wall mount can be facilitated and accelerated by pre-loading the locking counter-structure away from the engagement position.

[0017] The preloading of the locking structure away from the engagement position can be achieved solely by gravity, depending on the design and / or arrangement of the locking structure. However, to achieve defined preload forces and thus preload effects, a preloading element, such as a spring, is preferably provided, which preloads the locking structure away from the engagement position.

[0018] According to the invention, an actuating element, separately designed from the locking structure, is provided for unlocking an emergency ventilator assembly mounted on the wall bracket. The locking device therefore includes the actuating element, which interacts with the locking structure. The actuating element is movable between an inactive position and an active position. According to the invention, the active position differs from the inactive position. When in the active position, the actuating element allows the locking structure to be moved from the engagement position to the engagement preparation position by actuation towards the inactive position.

[0019] Preferably, when the actuator is in the inactive position, it cannot be actuated in a way that allows the locking structure to move from the engaged position to the engagement preparation position. Preferably, when the actuator is in the active position, it can be actuated in such a way that the actuation allows or even causes the locking structure to move from the engaged position to the engagement preparation position. To prevent incorrect actuation, the actuator may only be movable towards the active position when inactive, and / or the actuator may only be movable towards the inactive position when inactive.

[0020] A shift in the locking mechanism from the engagement position to the pre-engagement position allows the removal of an emergency ventilator assembly, initially locked to the wall bracket, from the wall bracket. While the locking mechanism only needs to be moved towards the pre-engagement position without actually reaching or stopping in it to unlock and release a locked emergency ventilator assembly, it is preferred that the locking mechanism is moved from the engagement position to the pre-engagement position when unlocking an emergency ventilator assembly mounted on the wall bracket.For this purpose, the locking structure is preferably pre-loaded away from its engagement position towards the engagement preparation position, particularly when it is in its engagement position, especially by the aforementioned pre-tensioning element.

[0021] To ensure that the intervention preparation position is reached and that the locking structure remains in this position, the locking structure is preferably pre-loaded or pre-tensioned away from the intervention position when no emergency ventilator assembly is mounted on the wall bracket. Particularly preferably, the locking structure is pre-loaded or pre-tensioned away from the intervention position along its entire displacement path between the intervention position and the intervention preparation position, preferably including the aforementioned positions.

[0022] Furthermore, preferably the locking structure and the actuating body interact functionally in such a way that a shift of the locking structure from the engagement preparation position to the engagement position permits or even causes a movement of the actuating body from the inactive position to the active position.

[0023] In a particular preferred embodiment, the locking structure can have a first locking stop which is designed to engage with a first locking counter-stop of the actuating body, wherein the first locking stop and the first locking counter-stop are in a first locking engagement when the locking structure is in its engagement preparation position and the actuating body is in its inactive position, the first locking engagement preventing movement of the actuating body into the active position. Thus, the locking structure can fix the actuating body in the inactive position as long as the locking structure is in its engagement preparation position or even until the locking structure is in the engagement position.The latter is preferred because, in this case, the actuating element, which is preferably visible and accessible for manual operation even when the emergency ventilator assembly is mounted on the wall bracket, can only move into the active position when the locking mechanism is in the engaged position. This allows it to be immediately determined from the position of the actuating element whether the emergency ventilator assembly is correctly mounted and locked to the wall bracket as intended, or whether the locking mechanism is unintentionally incomplete. This is an advantage of an inactive position that differs from the active position.

[0024] Preferably, the actuating body is pre-tensioned into the active position so that it preferably moves automatically into the active position as soon as the locking structure allows this movement by shifting into the engagement position.

[0025] For clarification, it should be noted that the ordinal numbers used here in naming attacks and interventions merely reflect the order in which the attacks and interventions are mentioned, but not necessarily a number or a functional order of attacks and interventions.

[0026] According to an advantageous embodiment of the present wall bracket, the actuating body may have a first displacement stop designed to engage with a first displacement counter-stop of the locking structure. The first displacement stop and the first displacement counter-stop are in a first positioning engagement when the locking structure is in its engagement preparation position and the actuating body is in its inactive position. This first positioning engagement prevents the locking structure from being displaced beyond its engagement preparation position in the direction of its preload. Thus, the actuating body can define the engagement preparation position of the locking structure.

[0027] Alternatively or additionally, the locking structure can have a second displacement stop, which is designed to engage with a second displacement counter-stop of the actuator. The second displacement stop and the second displacement counter-stop are then in a second positioning engagement when the locking structure is in its engaged position and the actuator is in its active position. This second positioning engagement prevents movement of the actuator from the inactive position to the active position beyond the active position. Thus, the locking structure can define the active position of the actuator.

[0028] Alternatively or additionally, the actuator can have a second locking stop, which is designed to engage with a second locking counter-stop of the locking structure. The second displacement stop and the second displacement counter-stop are then in a second locking engagement when the locking structure is in its engaged position and the actuator is in its active position. This second locking engagement prevents the locking structure from shifting out of its engaged position towards its engagement preparation position. This allows the actuator to lock the locking structure in its engaged position and prevent it from shifting out of it at least as long as the actuator is in the active position.

[0029] Thus, the two components – actuator and locking structure – and their operating positions – engagement preparation position and engagement position on the one hand, and inactive position and active position on the other – can mutually define and secure the two components in the aforementioned operating positions.

[0030] Preferably, the second locking mechanism can then be released by moving the actuating body from the active position towards the inactive position, preferably only by this movement, thereby enabling a shift of the locking structure from the engagement position to the engagement preparation position and thus a release of a previously locked emergency ventilator arrangement.

[0031] According to the invention, the actuating body and the locking structure are pre-tensioned towards each other, in particular in contact with each other, in order to ensure at least some, preferably all, of the above-mentioned contact engagements of the actuating body and locking structure, in particular the mentioned stops and counter-stops, with each other.

[0032] The number of components required to implement the locking device can be reduced by ensuring that the preload of the actuating body and the locking structure towards each other also preloads the locking structure into the engagement preparation position. Preferably, only one preloading element is provided, which both preloads the locking structure into the engagement preparation position and preloads the actuating body and the locking structure towards each other. Preferably, the preloading element is mounted with one bearing point on the actuating body and another bearing point on the locking structure. When using a tensile force-transmitting preloading element, such as a tension spring, the locking structure and / or the actuating body can advantageously be designed as space-saving single-arm pivot levers or slides.

[0033] The locking structure can be displaced translationally and / or rotationally between its engagement position and its engagement preparation position. Preferably, the locking structure is displaceable rotationally about a locking pivot axis. Particularly preferably, it is displaceable rotationally only about the locking pivot axis.

[0034] The actuating body can also be movable translationally and / or rotationally between its inactive and active positions. Preferably, the actuating body is rotatably movable about an actuating pivot axis. Particularly preferably, the actuating body is rotatably movable only about the actuating pivot axis.

[0035] In principle, the locking pivot axis and the actuating pivot axis can be oriented arbitrarily relative to each other. To simplify all the aforementioned engagement mechanisms, the locking pivot axis and the actuating pivot axis are preferably parallel or collinear. A parallel orientation of the two pivot axes, i.e., with a distance between them, is preferred, so that at least some of the aforementioned stops, preferably all of them, can be arranged on one and the same component associated with the respective pivot axis in a circumferential direction around this pivot axis, spaced apart from each other.

[0036] Preferably, during operation of the wall bracket, the locking structure can be moved from the engagement preparation position to the engagement position relative to the locking counter-structure. According to a structurally advantageous embodiment, this can be achieved by the locking structure having a groove for receiving the locking counter-structure. The groove can be bounded on one side by an actuating leg, by means of which the locking structure can be moved from the engagement preparation position to the engagement position, for example, by contact with the locking counter-structure. On the opposite side, the groove can be bounded by a locking leg, which, in the engagement position, defines a receiving space formed by the groove for receiving a locking counter-structure in a direction away from the base structure.

[0037] Preferably, in the engagement position, the locking structure not only prevents the positively locked counter-structure from being removed from the base structure, but also prevents its movement parallel to the base structure in a direction that would allow the insertion counter-structure to be removed from the insertion structure.

[0038] The locking device can have a locking housing that is rigid relative to the base structure, in which the locking structure is movably mounted. Preferably, the actuating element is also movably mounted on the locking housing, the actuating element having an actuating section that is located outside the locking housing, at least in the active position. By actuating the actuating section, and thus by moving the actuating element from the active position to the inactive position, an emergency ventilator assembly locked by the locking device can be unlocked, as described above.

[0039] The locking housing can also have a groove into which the locking counter-structure of the emergency ventilator assembly can be inserted and relative to which the locking structure is pivotable. For example, in the engaged position, the locking arm can close off an insertion path of the rigid groove of the locking housing. In the engagement preparation position, the locking arm can be located outside the rigid groove of the locking housing, in which case the actuating arm preferably projects into the rigid groove of the locking housing in order to be physically engaged by a locking counter-structure inserted into the rigid groove of the locking housing and, by the movement of the locking counter-structure, be moved into the engagement position together with the entire locking structure.

[0040] Preferably, the groove of the locking housing is designed and oriented such that, together with the locking structure adjusted to its engagement position, it is able to withstand the weight of an emergency ventilator assembly locked by the locking structure, preferably with a support frame attached to it, even without further support of the emergency ventilator assembly, such as by the suspension structure, and thus prevent the emergency ventilator assembly from falling even if its suspension counter-structure was accidentally not correctly engaged in the suspension structure or if the suspension structure was damaged or even fell off.

[0041] The mounting structure may include or be a hook, a groove, a rod positioned at a distance from the base structure, and / or a rail positioned at a distance from the base structure.

[0042] The base structure can comprise a panel, a frame, and / or a truss structure that can be attached to the wall. For the most secure possible attachment to the wall, the base structure can have at least one through-hole, preferably multiple through-holes, through which fasteners such as screws, nails, and the like can be inserted. In the fully assembled state, a fastener is advantageously surrounded by the edge of a through-hole along its entire circumference. The base structure can be a single piece or can be made up of multiple parts. For example, both the locking device and the mounting structure can each have a separate partial base structure for their respective wall mounting.However, to ensure the correct relative arrangement of the locking device and the mounting structure to each other, the use of a common, structurally coherent base structure for the locking device and the mounting structure is preferred.

[0043] The reference surface can be defined by a single surface on the mounting side, designed for contact with the wall that supports the wall bracket during operation. If a cranked plate, truss, or cranked frame is used as the base structure, it can be defined by a plurality of sub-surfaces. Preferably, several of these sub-surfaces, and preferably each sub-surface, have at least one through-opening. The reference surface is preferably a reference plane, since the wall bracket is generally mounted on a substantially flat wall. The sub-surfaces are generally connected by base structure sections whose outer surface lies outside the reference surface on the mounting side. In this sense, the multiple sub-surfaces that together define the reference surface are unconnected within the reference surface.

[0044] Furthermore, the basic structure preferably comprises a connector assembly with at least one electrical contact, preferably with a plurality of contacts, for transmitting electrical energy and / or data. Accordingly, the emergency ventilator assembly preferably comprises a connector counter-assembly that is compatible with, and preferably complementary to, the connector assembly. To facilitate handling, the connector assembly and the connector counter-assembly are arranged on their respective components such that an electrically conductive connection between the connector assembly and the connector counter-assembly is automatically established when the emergency ventilator assembly is detachably mounted on the wall bracket for remaining there.

[0045] The present invention further relates to a rescue arrangement comprising a wall bracket as described and further developed above, and further comprising an emergency ventilator arrangement with a counter-structure that can be suspended into the mounting structure and with a locking counter-structure arranged at a distance from the mounting counter-structure, wherein the locking counter-structure can be brought into locking engagement with the locking structure. The counter-structure can also comprise or be a hook, a groove, a rod and / or a rail, depending on how the mounting structure is designed.

[0046] The emergency ventilator setup can include or consist of an emergency ventilator. It can additionally include a carrying frame with which the emergency ventilator can be carried from the wall mount to the point of use and back. The carrying frame can be designed to be detachably or permanently connected to the emergency ventilator.

[0047] To avoid the efforts of rescue personnel being disrupted by moving parts on the emergency ventilator assembly during operation at an accident site or the like, the mounting counter-structure and the locking counter-structure are preferably arranged immovably on the emergency ventilator or on a support frame of the emergency ventilator assembly that can be coupled or coupled to the emergency ventilator.

[0048] To facilitate the mounting of the emergency ventilator assembly on the wall bracket, it can be provided that the emergency ventilator assembly, with its mounting structure, is pivotable about a pivot axis parallel to the reference surface when only suspended from the mounting structure. The emergency ventilator assembly can then be mounted on the wall bracket by first attaching the mounting structure to the mounting structure and then pivoting the suspended emergency ventilator assembly about the pivot axis towards the base structure, so that the locking structure and the locking structure approach each other until the locking mechanism engages, preferably guided along a defined path by the engagement of the mounting structure and the mounting structure. Due to the described preload, or...Preloading occurs when the locking counter-structure and locking structure are sufficiently close together. This results in the displacement of the locking structure into the engagement position and the fixing of the locking structure in the engagement position by the actuating body solely through the approach movement of the locking counter-structure towards the base structure or towards the locking structure.

[0049] Preferably, a structure consisting of a suspension structure and a counter-suspension structure has a concave surface, while the other structure has a convex surface, with the two surfaces designed to abut each other. In the suspended state, the concave surface surrounds the convex surface on at least two, preferably three, sides. Without further securing, such as by a locking structure, a structure consisting of a suspension structure and a counter-suspension structure can be lifted or lowered from each other in the suspended state in order to detach the counter-suspension structure from the suspension structure.

[0050] To enable the emergency ventilator assembly to be removed from the wall bracket as quickly, easily, and safely as possible, the actuator has an operating section designed for manual operation. Furthermore, the emergency ventilator assembly preferably has a carrying handle designed for manual gripping. The carrying handle is preferably part of a support frame for the emergency ventilator assembly. To allow for immediate visual confirmation that the emergency ventilator assembly is correctly locked to the wall bracket, the operating section is positioned at a different distance from the carrying handle in the inactive position than in the active position, when the emergency ventilator assembly is positively locked or locked to the wall bracket by the locking mechanism.Preferably, the distance in the active position of the actuator is chosen such that at least one finger of the hand that grasps the carrying handle when removing the emergency ventilator assembly from the wall bracket can actuate the actuator section towards the inactive position of the actuator. This allows the emergency ventilator assembly to be grasped with one hand, its locking mechanism on the wall bracket to be released, and the emergency ventilator assembly to be removed from the wall bracket with one hand.

[0051] The carrying handle preferably comprises a bracket at at least one longitudinal end, and more preferably a bracket at each of its two longitudinal ends, by means of which the carrying handle is connected to the emergency ventilator. Preferably, the carrying handle is fixedly connected to the emergency ventilator relative to it. However, this does not preclude the possibility that components, such as hooks, are arranged on the support frame, and in particular on the carrying handle itself, so that they are movable relative to it. These hooks can be rotatably arranged on the support frame about an axis of rotation parallel or coaxial with the longitudinal axis of the carrying handle, in order to suspend the emergency ventilator assembly from a suitable structure at its point of use.To prevent unintentional activation of the actuating section, the actuating section, when mounted on the wall bracket and locked in place with the actuator in the active position, is preferably surrounded by a structure. The structure surrounding the actuating section preferably comprises a section of at least one bracket and the carrying handle.

[0052] The present invention will be explained in more detail below with reference to the accompanying drawings. It illustrates: Fig. 1 a perspective view of a rescue arrangement comprising a wall bracket of the present invention and an emergency ventilator arrangement detachably held thereon, the latter in turn comprising an emergency ventilator and a support frame fixed to the emergency ventilator, Fig. 2 a further perspective view of the rescue arrangement of Fig. 1, viewed more strongly from above, Fig. 3 a partially cutaway side view of the rescue arrangement of the Fig. 1 and 2 , with emergency ventilator assembly suspended in the mounting structure but otherwise unlocked, Fig. 4 a partially cutaway side view of the rescue arrangement of the Fig. 3 , with emergency ventilator assembly suspended in the mounting structure and compared to Fig. 3 the locking device more closely approximating the locking counter-structure, and Fig. 5 a partially cutaway side view of the rescue arrangement of the Fig. 4 , with emergency ventilator arrangement locked to the wall bracket.

[0053] In the Figures 1 to 5A rescue arrangement of the present invention is generally designated by 10. The rescue arrangement 10 comprises a wall bracket 12 and an emergency ventilator arrangement 14. The emergency ventilator arrangement 14 in turn comprises an emergency ventilator 16 (hereinafter referred to as "ventilator") and a support frame 18 connected to the ventilator 16.

[0054] The ventilator 16 is, by way of example, prism-shaped, with a square, rounded cross-sectional area, wherein a control unit 20 with a monitor 22 is arranged on one side of the outer surface of the ventilator 16.

[0055] At his in Figure 1 During ventilation operation, the ventilator 16 draws in ambient air as breathing gas through an opening 24 in a lid 26 locked by a bayonet fitting on the front side facing the viewer.

[0056] The support frame 18 has a carrying handle 28, which extends along a virtual longitudinal axis TL. On either side of the carrying handle 28, a hook element 30 is rotatably arranged about the longitudinal axis TL as an axis of rotation. The hook elements 30 can be locked in a desired relative rotational position with respect to the carrying handle 28 by clamping devices 32. The support frame 18 also has a bracket 34 on either side of the carrying handle 28. The brackets 34 connect the carrying handle 28 to the ventilator 16.

[0057] The carrying handle longitudinal axis TL runs parallel to a virtual prism longitudinal axis PL that is imagined to pass centrally through the ventilator 16.

[0058] On its discharge front, which is opposite the intake front and which the viewer sees from Figure 2 As can be seen, there are connection arrangements 36 for the delivery of respiratory gas to a patient.

[0059] The wall bracket 12 comprises a base structure 38, in the illustrated embodiment in the form of a flat plate, which has a plurality of through holes 39 for fastening to a wall. The emergency ventilator assembly 14 is accommodated on the receiving side 38a. The opposite mounting side 38b is designed to rest against a, preferably flat, wall surface and defines a reference plane BE parallel to the hypothetical wall surface (see Figures 3 to 5 ) as the reference surface mentioned in the introductory description. The reference plane BE is orthogonal to the drawing plane of the Figures 3 to 5 oriented.

[0060] On the receiving side 38a of the base structure 38 there is a locking housing 40 with a locking device 42. From the locking housing 40, an actuating section 44a of an actuating body 44 protrudes through an opening 41 on its side facing the carrying handle 28.

[0061] In Figure 3 Figure 1 shows how an actuating arm 46 of a locking structure 48 protrudes from the locking housing 40 on a side facing the ventilator 16. The locking structure 48 is located in Figure 3 in its prepared position for intervention. The locking structure 48 has, for example, a U-shaped form as a hook component.

[0062] The actuating leg 46 defines a groove 50 in the locking structure 48 on one side. On the opposite side, the groove 50 is defined by a locking leg 52 of the preferably one-piece locking structure 48.

[0063] The groove 50 serves as a receiving space for a locking counter-structure 54 in the form of an exemplary cylindrical rod, which is rigidly attached to the support frame 18 (cf. Fig. 5 ).

[0064] The locking structure 48 is extended to the drawing planes of the Figures 3 to 5orthogonal locking pivot axis RA rotatorily from the in Figure 3 shown pre-operative position in the Figure 5 shown intervention position - when considering the Figures 3 to 5 clockwise - repositionable.

[0065] The actuating body 44 with its actuating section 44a is located in Figure 3 in its inactive position. It is removed from this position by an actuating pivot axis BA from the in Figure 3 shown inactivation in the Figure 5 shown active position rotary - when considering the Figures 3 to 5 Movable clockwise.

[0066] In the illustrated embodiment, the locking pivot axis RA and the actuating pivot axis BA are parallel to each other. They are preferably also parallel to the reference plane BE.

[0067] A spring 56, in the illustrated example a coiled tension spring, biases the locking structure 48 in the engagement preparation position in one direction away from the engagement position. The same spring 56 biases the actuating body 44 in the direction towards its active position. The spring 56 is articulated at one end to the actuating body 44 and at the other end to the locking structure 48.

[0068] Due to the preload of the spring 56, a first locking stop 58 of the locking structure comes into contact with a first locking counter-stop 60 of the actuating body 44. This first locking engagement physically prevents the actuating body from moving from its inactive position towards the active position.

[0069] Likewise, due to the preload of the spring 56, a first displacement stop 62 of the actuating body 44 comes into contact with a first displacement counter-stop 64 of the locking structure 48. This first positioning engagement prevents the locking structure 48 from displacing beyond the engagement position in the direction of its preload by the spring 56 and away from the engagement position.

[0070] Thus, the actuating body 44 and the locking structure 48 mutually define their properties through the aforementioned reciprocal engagements. Figure 3 The operating positions shown are, namely, inactive position and intervention preparation position.

[0071] The aforementioned first stops of the actuating body 44: first locking counter-stop 60 and first displacement stop 62, are, in the illustrated embodiment, formed on a stop component 65 that is separate from the rest of the actuating body 44 and is fixed to the rest of the actuating body 44. This allows for particularly durable stops 60 and 62 to be realized through suitable material selection. In principle, at least one of the aforementioned stops 60 and 62, and preferably both stops 60 and 62, can be formed integrally with the actuating body 44.

[0072] When the wall bracket 12 is fully mounted on a wall, it is located in the direction parallel to the drawing planes. Figures 3 to 5In the direction of the acting force of gravity g below the locking device 42, a suspension structure 66 is rigidly connected to the base structure 38, realized in the illustrated embodiment by a concave suspension groove. The ventilator assembly 14 can be suspended in the suspension structure 66.

[0073] The ventilator assembly 14 features, for example, a cylindrical rod as the mounting counter-structure 68. This rod can be identical to the locking counter-structure 54, but arranged at a distance from it. In the illustrated embodiment, the rods of the locking counter-structure 54 and the mounting counter-structure 68 are parallel to each other, to the longitudinal axis PL of the prism, and to the longitudinal axis TL of the carrying handle.

[0074] When the mounting structure 68 is inserted into the mounting structure 66, and thus the ventilator assembly 14 is suspended from the mounting structure 66, the ventilator assembly 14 can be pivoted about the pivot axis SA. The pivot axis SA forms the, preferably common, axis of curvature of the concave mounting groove of the mounting structure 66 and the convex outer circumferential surface of the cylindrical rod of the mounting structure 68. The pivot axis SA is therefore collinear with the longitudinal axis of the cylindrical mounting structure 68. The pivot axis SA is parallel to the reference plane BE and is preferably also parallel to the longitudinal axis TL of the carrying handle and to the longitudinal axis PL of the prism. Particularly preferably, the pivot axis SA is also parallel to the axes BA and RA.

[0075] The locking housing 40 includes a housing groove 70 into and out of which the locking counter-structure 54, usually together with the entire ventilator assembly 14, can be pivoted about the pivot axis SA. In the Figure 3 In the shown engagement preparation position of the locking structure 48, only the actuating leg 46 projects into the housing groove 70, whereas the locking leg 52 is mostly, preferably completely, outside the housing groove 70 or in the locking housing 40.

[0076] If the ventilator assembly 14 is attached to the mounting structure 66 after being suspended - when considering the Figures 3 and 4 - pivoted counterclockwise around the pivot axis SA, the locking counter-structure 54 enters the housing groove 70 and thus comes into contact with the actuating arm 46. This intermediate operating state is in Figure 4 depicted.

[0077] During the continued counterclockwise rotation of the ventilator assembly 14, the actuating arm 46 is moved towards the base structure 12 by the engagement of the locking counter-structure 54. This shifts the locking structure 48 towards the engagement position against the preload of the spring 56, thereby increasingly tensioning the spring 56. The preload force of the spring 56 thus increases as the locking structure 48 approaches its engagement position.

[0078] By rotating the locking structure 48 from the engagement preparation position of Figure 3 for the intervention position of Figure 5Initially, the first displacement stop 62 and the first displacement counter-stop 64 disengage. The first positioning engagement is thus released. The first locking engagement, however, remains. Preferably, the first locking stop 58 has a curved stop surface whose axis of curvature is the locking pivot axis RA of the locking structure 48. The curved stop surface of the first locking stop 58 can be curved about more than this one axis of curvature. For example, it can be designed as a spherical cap. However, it is preferably curved at least about the locking pivot axis RA as its axis of curvature.

[0079] If the pivoting movement of the ventilator assembly 14 continues, the locking counter-structure 54 presses the locking structure 48 into the position via the insertion engagement with the actuating arm 46. Figure 5The depicted intervention position. For clarity, in Figure 5 The stops on the locking structure 48 and on the actuating body 44, which have been explained so far, are not labelled again.

[0080] The locking structure 48 is moved towards the engagement position by the continued pivoting movement of the ventilator assembly 14 until the first locking engagement between the first locking stop 58 and the first locking counter-stop 60 is also released. This gives the actuating body 44 room to pivot into the active position. The actuating body 44 pivots when viewed from the Figures 3 and 4clockwise until a second displacement counter-stop 74 of the actuating body 44 engages in positioning engagement with a second displacement stop 72 of the locking structure 48. This positioning engagement, together with the preload force of the spring 56, defines the active position of the actuating body 44.

[0081] Simultaneously, a second locking stop 76 of the actuating body 44 engages in a second locking engagement with a second locking counter-stop 78 of the locking structure. This second locking engagement prevents the locking structure 48 from moving from its engaged position towards its engagement preparation position, into which it is biased by the spring 56.

[0082] The actuating body 44 and the locking structure 48 again work together to mutually define their respective operating positions: active position and engagement position.

[0083] The first locking stop 58 and the second displacement stop 72 of the locking structure 48 are arranged one behind the other in the circumferential direction around the locking pivot axis RA on the locking structure 48. The same applies to the first displacement counter-stop 64 and the second locking counter-stop 78.

[0084] Similarly, the first locking stop 58 and the second displacement stop 72 of the locking structure 48 are designed with different axial distances from the locking pivot axis RA. The same applies to the first displacement counter-stop 64 and the second locking counter-stop 78.

[0085] On the actuating body 44, the first locking stop 60 and the second displacement stop 74 are preferably formed by the same stop surface. Likewise, the first displacement stop 62 and the second locking stop 76 are preferably formed by the same stop surface, which, however, differs from that of the aforementioned stops 60 and 74.

[0086] When the emergency ventilator assembly 14 is locked to the wall bracket 12, the actuating arm 52 engages the locking counter-structure 54, so that the locking structure 48 with its locking arm 46 prevents the locking counter-structure 54 and with it the entire emergency ventilator assembly 14 from being removed from the base structure 38 by positive locking (see Fig. 5 ).

[0087] The groove 50 is dimensioned such that the locking structure 48 in the engagement position prevents the mounting counter-structure 68 from lifting off the mounting structure 66 and thus prevents the ventilator assembly 14 from being unhooked from the mounting structure 66.

[0088] In the active position, the actuating section 44a of the actuating body has a different, preferably shorter, distance from the carrying handle 28 when the ventilator assembly 14 is arranged on the wall bracket 12 in a ready-to-lock or locked position. This allows it to be immediately recognized at a glance whether the ventilator assembly 14 has been correctly locked on the wall bracket or whether the ventilator assembly 14 is merely in a ready-to-lock position on the wall bracket 12, but a correct locking has not taken place, for example because components that should be movable relative to each other are jammed or dirty.

[0089] In the active position, with the ventilator assembly 14 locked to the wall bracket 12, the actuating section 44a of the actuating body 44 can be reached by a finger of the hand that is grasping the carrying handle 28 to remove the ventilator assembly 14 from the wall bracket 12. Thus, one-handed operation is possible.

[0090] When the actuating section 44a is actuated from the active position towards the inactive position, the second positioning engagement between the second displacement counter-stop 74 and the second displacement stop 72 is first released, whereas the second inhibiting engagement remains in place and the second inhibiting stop 76 slides along the second inhibiting counter-stop 78.

[0091] If the actuating body 44 is moved further towards the inactive position via the actuating section 44a, the second locking stop 76 also eventually comes out of contact with the second locking counter-stop 78. This occurs when the trailing end of the second locking stop 76, which moves into the inactive position when the actuating body 44 is moved beyond the end of the second locking counter-stop 78 furthest from the second displacement stop 72. Due to the preload of the spring 56, the locking structure is then moved from the engaged position to the engagement preparation position until the first displacement counter-stop 64 of the locking structure 48 again comes into the first positioning contact with the first displacement stop 62 of the actuating body 44.The locking structure 48 is then in the intervention preparation position and the ventilation device assembly 14 can be removed from the wall bracket 12, as it were with the support of the spring 56 as a kind of "ejector spring".

[0092] When the manual actuation of the actuating section 44a ends, the spring 56 tensions the first escapement stop 58 and the first escapement counter-stop 60 against each other, thus restoring the first escapement engagement. The operating state of the locking device 42 then corresponds again to that of Fig. 3 .

[0093] In the activated position of the actuator 44, the actuating section 44a is located between the brackets 34, so that it is not easily accessible from the side, at least not without collision with the brackets 34. The actuating section 44a is shielded between the brackets 34 by the carrying handle 28, so that it is also not easily accessible for actuation from an oblique angle above. In fact, in the activated position of the actuator 44, the actuating section 44a is located in a receiving space virtually enclosed by the brackets 34 and the carrying handle 28, which largely prevents incorrect actuation of the actuator 44.

[0094] In the inactive position of the actuating body 44, the base structure 38 prevents movement of the actuating body 44 away from the active position. Therefore, the actuating body 44 is preferably only movable towards the active position in the inactive position and preferably only movable towards the inactive position in the active position.

[0095] A cover 80 arranged inside the locking housing 40, preferably in one piece, on the actuating body 44 closes the opening 41 in each of the operating positions of the actuating body 44 and thus protects against dirt entering the locking housing 40.

[0096] For the sake of completeness, the following is included in the Figs. 3 to 5A DC connector 82 is symbolically provided on the receiving side 38a of the base structure 38, which automatically establishes an electrically conductive contact with a mating connector 84 (also only symbolically indicated) in the ventilator 16 when the emergency ventilator assembly 14 is properly mounted on the wall bracket 12. As long as the emergency ventilator assembly 14 is properly locked onto the wall bracket 12, an accumulator of the emergency ventilator assembly 14 can be charged via the established electrical contact and / or data can be transferred from a control and / or data storage device of the ventilator 16 to an external module.
