Definitions
- the present invention relates to a viewing window for insertion into a viewing opening, in particular a viewing opening of an air conditioning system and / or a climate chamber, with two disc carriers which can be connected to one another via a rotary connection.
- HVAC systems room-air-technical systems
- climatic chambers are equipped with various types of machines, systems, system parts, units, etc. for various applications.
- HVAC systems or climatic chambers usually have a closed system housing in which different operating or there may be climatic conditions, some of which differ significantly from the ambient conditions outside the system housing.
- inside the system housing there can be conditions with both positive and negative pressure, various temperature and / or humidity conditions, etc., which is why the walls of the system housing are generally designed to be pressure-tight and heat-insulated.
- the system housings are usually used from an inner and an outer metal sheet with a sandwich-like filler, which has insulation, insulation and other properties adapted to the respective application.
- viewing openings with viewing windows inserted therein are provided at certain points in the system housing, which in practice are often designed like portholes and are located in one Side wall or door of the system housing can be.
- Such a viewing window is known from DE 10 2017 105 267 A1.
- the panes which are made of a transparent material, are arranged on pane carriers, which can be inserted into the viewing opening from opposite directions and mounted there.
- the two disc carriers are mounted in the viewing opening via a rotary connection, in that the two disc carriers are rotated relative to one another and are mounted in the viewing opening in the manner of a screw connection.
- one of the two disk carriers is screwed to the wall of the system housing after assembly. In this way, an unwanted loosening of the pane carrier, for example in the case of stronger vibrations or similar influences, is reliably prevented even over longer periods of time.
- An advantageous embodiment of the invention provides that the detent is functionally coupled to the rotary connection. Due to the functional coupling of the slewing ring with the detent mechanism, when actuated the slewing ring also immediately activates the locking device and the slewing ring is automatically secured in its respective rotational position. There is therefore no need for any additional steps to activate the safety catch.
- the ratchet is formed out like a ratchet. Due to the ratchet-like design of the detent device, the rotary connection can be secured at discrete intervals and thus angles of rotation.
- the detent device has at least one detent element arranged on the one pane support and several detent elements arranged on the other pane support.
- the locking element arranged on the one disc carrier can lock on several locking elements of the other disc carrier in different locking positions and in this way secure the rotary connection in different positions against unwanted loosening.
- two locking devices are arranged on the one disk carrier on opposite circumferential regions of the one disk carrier, each of which is assigned a plurality of second ras elements on the other disk carrier.
- the latching elements arranged on the other disk carrier have a predetermined latching distance.
- the rotation lock can be done at larger or finer angular intervals.
- a structurally advantageous embodiment provides that the plurality of latching elements have an undulating, serrated and / or scale-like contour.
- a wave-shaped contour allows the disc carriers to be rotated in both their connection and solution direction. tion with essentially the same effort. The same can apply to a jagged contour.
- the scale shape can be chosen so that there is a greater resistance to unwanted loosening than when connecting the two disc carriers together.
- the barb geometry of the latching elements can be chosen such that the two disk carriers cannot be separated from one another without destruction after assembly.
- the latching elements have a predetermined latching distance. The angular division of the locking device can be adjusted via the locking distance. In the case of a smaller distance, there is a finer angle division and thus the possibility of a finer detent.
- the plurality of latching elements form a latching section.
- the locking elements can be arranged one after the other in the manner of a string of pearls.
- the other latching element can be moved along the latching section and can snap into different latching positions in the latching section.
- a further embodiment of the invention provides that the one disc carrier for generating the rotary connection has at least one tab-shaped fastening means which can be brought into engagement with at least one spiral-shaped fastening means of the other disc carrier to form the rotary connection.
- the rota toric movement corresponding to the slope of the spirally formed fastening means is converted into a translational movement and the two disk carriers coming from the axial direction are fixed in the viewing opening.
- the plurality of latching elements are assigned to the fastening means, which is at least partially spiral-shaped. In this way, a coupling between the rotary connection and the reverse rotation lock can be realized in a favorable manner.
- the latching section is arranged parallel to the fastening means, which is at least partially spiral-shaped. In this way, the slewing ring can be produced in a compact manner and the locking device can be achieved.
- a latching section is advantageously assigned to each fastening means which is at least partially spiral-shaped. In the case of a plurality of spiral-shaped fastening means, these can optionally be used and, regardless of this choice, a separate latching section is available for the latching device.
- a further structural embodiment provides that a latching element is arranged on the tab-shaped fastening means.
- the locking device can be generated in the area of the rotating connection using the fastening means.
- the latching element can protrude from the engagement element, for example in the manner of a latching lug.
- the locking lug can interlock positively in the locking contours of the locking distance in different locking positions.
- the latching element is designed to be latchable in an intermediate region between two latching elements.
- the locking can be done in a positive and / or non-positive manner.
- the latching element it is finally proposed that it be made narrower and / or shorter than the fastening means. In this way, the locking element can be removed from the power flow of the rotary connection and only serve to secure the locking.

- the system housing 100 which is accessible via a door 101 in the exemplary embodiment according to FIG. 1, various machines, systems, system parts, units and the like can be arranged.
- two viewing windows 1 are provided in the exemplary embodiment according to FIG Inside the system housing 100 brought systems and machines without having to open door 101.
- One viewing window 1 is arranged in the door 101, the other viewing window 1 in a housing wall 102.
- the viewing windows 1 are designed and mounted identically for both wall and door mounting, which is why the following explanations are concentrated on wall mounting. It goes without saying that the viewing window 1 can also be mounted in a door 101 in the same way.
- the construction and assembly of the viewing window 1 are first of all explained in general below on the basis of the illustrations in FIGS. 2 to 15, before then on the basis of the illustrations in FIGS. 16 to 21 for details of the locking device 31 of the viewing window 1 and on the basis of FIG 22 to 27 deal with details of a lighting element 50 of the viewing window 1 who will.
- the viewing window 1 is of cylindrical geometry and is inserted into an approximately cylindrical viewing opening 2 within a housing wall 102 of the system housing 100.
- the viewing window 1 is composed of two parts. One part of the viewing window 1 is formed by a pane support 3 which is inserted into the viewing opening 2 from one side of the housing sewing wall 102 along the direction Ri. The second part of the viewing window 1 is formed by a further pane support 4 which is inserted into the viewing opening 2 along the direction Ri from the opposite side of the housing wall 102.
- the housing wall 102 of the system housing 100 can be, for example, a solid housing wall 102 or a sandwich-like one, made of metallic surfaces and one in between Act housing wall 102 formed insulation, which is provided with the viewing opening 2 designed in the manner of a through hole.
- the viewing window 1 is inserted in a gas-tight manner in the viewing opening 2 of the housing sewing wall 102 in a manner which is easy to assemble and leakage-prone to leakage.
- sealing elements 17, 18 are provided on both sides of the solid housing wall 102 in FIG. 2 made of a rubber-elastic material.
- the sealing elements 17, 18 are clamped between a circumferential collar of the disk carriers 3, 4 and the opposite edge 2.2 of the viewing opening 2.
- the one you telement 18 has a round cross section and the other sealing element 17 has a rectangular cross section, wherein other cross sections would also be conceivable.
- Both sealing elements 17, 18 are of ring-shaped geometry and extend along the edge 2.2 of the viewing opening 2 around them.
- FIGS. 3 and 4 each show the two disk carriers 3 and 4 separately in a perspective view.
- the disk support 3 is designed like a lid and carries a window pane 11 made of optically transparent material.
- a window pane 11 is provided in the window frame 7.
- the window frame 7 is followed by a fastening section 9 with a smaller diameter.
- the fastening section 9 is of tubular geometry and in the embodiment in one piece with the window frame 7.
- both the window pane 11 and the window frame 7 surrounding it, as well as the fastening section 9, are made of an optically transparent material and in particular a plastic material.
- the disk carrier 3 would be made from two pieces.
- the advantage of the non-transparent area 9 would be that it would not be possible for an observer to look diagonally through the viewing window 1 over the inner circumferential surface 2.1 of the viewing opening 2 into the interior of the housing wall 102, where, for example, in the case of a sandwich-like housing wall 102 there is a mineral insulation material.
- the pane carrier 3 has a fastening means 5 which is designed such that it interacts with a corresponding fastening means 6 of the other pane carrier 4 as a result of a relative movement of the two fastening means 5, 6.
- the fastening means 5 is formed by two radially inwardly projecting tabs. More tabs can also be used as fasteners 5. It would also be conceivable to use tabs with a more spiral shape. The tabs can also be made longer or shorter. It is important that these are suitable to enter a spiral of the other fastening means 6 and to fasten the disk supports 3, 4 in the viewing opening 2.
- Fig. 4 shows the other disc carrier 4 in a perspective view.
- the pane support 4 has a window pane 12 made of transparent material.
- the window pane 12 is surrounded by a window frame 8, to which a fastening section 10 connects.
- the configuration of the disc carrier 4 is the same as that of the disc carrier 3.
- the disc carrier 4 can also be made of one piece in a transparent be made of material or the fastening area 10 can be designed as a separate piece in an opaque material.
- the fasteners 6 are formed in the disc carrier 4 by spiral-shaped or partially spiral elements which are arranged on the circumference of the cylindrical fastening portion 10.
- the fastening means 6 are formed by a total of three spiral spiral sections 6.1, 6.2 and 6.3, which are arranged offset with respect to one another in the direction of the mounting axis M of the viewing window 1. Basically, a single such spiral spiral section 6.1, 6.2 or 6.3 would be sufficient for mounting the viewing window 1. Through several spiral coil sections, however, a possibility for rapid adaptation of the viewing window 1 to different wall thicknesses of the housing wall 102 is created, which will be explained in more detail below.
- spiral coil sections 6.1, 6.2 and 6.3 are not continuous, but are provided on two opposite sides in accordance with the number of fasteners 5 of the other disk carrier 3 with an insertion opening 13 into which the fastener 5 of the other disk carrier are inserted can.
- the insertion openings 13 are of channel-shaped cross section. In order to facilitate insertion, the insertion openings 13 are provided with an insertion bevel 14 on the insertion side.
- FIGS. 8 to 11 The processes in the assembly of the two disc carriers 3, 4 to a common viewing window 1 are illustrated in FIGS. 8 to 11.
- the two pane supports 3, 4 are first moved toward one another along the mounting axis M from opposite directions Ri, Ri.
- the tab-like fasteners 5 enter the region of the insertion opening 13 until the two pane supports 3, 4 with their window frames 7, 8 come to the edge of the viewing opening 2 and further axial movement is no longer possible.
- the window frames 7, 8 form stops.
- an anti-rotation device 19 arranged on the one disk carrier 4 interacts with a counter-contour on the housing wall 102 in such a way that the disk carrier 4 can no longer be rotated within the viewing opening 2.
- the rotation 19 is formed by a form-locking element which is arranged on the window frame 8 of the disk carrier 4 and interacts positively with a counter-structure on the housing wall 102.
- the anti-rotation device 19 is formed by a projection and the counter structure on the housing wall 102 is formed by a recess. Alternatively, however, it would also be possible for the anti-rotation device 19 to be formed by a recess and the counter structure on the housing wall 102 to be formed by a projection.
- the one disc carrier 3 relative to the other disc carrier 4 is moved relatively and thereby the fasteners 5, 6 actuated, ie the fasteners 5, 6 are brought into engagement with each other.
- the relative movement is a relative rotation of the two disk carriers 3, 4, as a result of which they are connected to one another in a screw-like manner via a rotary connection 30.
- the disk support 4 is also prevented from rotating in the viewing opening 2 by the anti-rotation device 19.
- the tab-like fastening means 5 first enter the area of the spiral spiral sections 6.1, 6.2, 6.3, cf. also the representations in FIGS. 10 and 11.
- the disk carriers 3, 4 move in the axial direction while compensating for any manufacturing tolerances towards the housing wall 102 until the sealing elements 17, 18 are sufficiently compressed and the viewing window is seated pressure-tight in the viewing opening 2.
- three spiral coils 6.1, 6.2, 6.3 are provided, which serve as wall thickness compensation for different wall thicknesses of the housing wall 102 of the system housing 100 in the region of the viewing opening 2, so that one and the same viewing window 1 can be used for different wall thicknesses. This is explained below with reference to the representations in FIGS. 12-14.
- Fig. 12 is a view of the assembled viewing window 1 in egg ner viewing opening 2 of a comparatively thin housing wall 102 the disk carrier 4 is closest, and secured there by twisting.
- Fig. 13 shows an installation situation in a viewing opening 2 of a housing wall 102 of medium thickness, in which the fastening means 5 behind the middle spiral coil section 6.2 come to the position.
- 14 finally shows an installation situation in which the fastening means 5 bear against the spiral coil section 6.3, which is arranged at the front end of the fastening section 10.
- the viewing window 1 can optionally be used in housing walls 102 of different thicknesses. For this purpose, it is not necessary to make any structural changes to the viewing window 1.
- FIG. 15 shows once again the processes involved in mounting the viewing window 1 in an exploded view, the two window carriers 3, 4 of which are inserted in a housing wall 102 from two opposite directions in the manner of a double-glazed porthole.
- the two disk carriers 3, 4 can be used without additional fastening elements, such as in particular screw bolts and similar elements, in a pressure-tight and simple and easy-to-install manner in the viewing opening 2 of a system housing 100 and fastened there by a rotary connection 30. Since the details of the locking device 31 and the lighting element 50 are not shown in FIGS. 1 to 15 for reasons of clarity, are not shown these are explained below with reference to the representations in FIGS. 16 to 27 in detail.
- a difference compared to the previously described viewing window 1 in the embodiment according to FIGS. 16 to 27 is that the viewing window 1 is not inserted into a solid housing wall 102 of a system housing 100, but rather into a housing wall 102 constructed in a sandwich construction, cf. 15 and 16.
- the housing wall 102 in this embodiment has a multi-layer construction with two plate-shaped elements 103, which can in particular be metal sheets.
- a space 104 for receiving a filler is provided between the elements 103.
- the filler can be, for example, a mineral insulating wool or a similar filler.
- the viewing window 1 basically corresponds to the features described above and differs due to the sandwich construction of the housing wall 102 only in that an intermediate ring 40 is arranged in the area between the plate-shaped elements 103, which is not required in the case of a solid housing wall 102.
- the intermediate ring 40 is arranged in the region of the viewing opening 2 between the plate-shaped elements 103 and surrounds the viewing opening 2 in a concentrically outwardly displaced position.
- the intermediate ring 40 has a separation point 42, cf. also FIG. 26. By loosening the separating point 42 temporarily, the intermediate ring 40 can be deformed for assembly purposes such that it extends over the smaller viewing opening 2 in the area between the window frame shown in FIGS. 16 and 17 7, 8 and arrange accordingly.
- the intermediate ring 40 fulfills several functions in the sandwich-like housing wall 102. The main function of the intermediate ring 40 is first of all to achieve pressure-tight support of the two plate-shaped elements 103.
- the plate-shaped elements 103 are formed from thin-walled and thus easily deformable metal sheets.
- the intermediate ring 40 therefore sits between the window frames 7, 8 of the pane supports 3, 4.
- the thin-walled elements 103 are therefore not deformed inward, but are pressed against the end faces of the intermediate ring 40 and supported there . This prevents undesired deformations of the elements 103.
- the intermediate ring 40 also has a sealing function.
- the intermediate ring 40 has a sealant receptacle 41 on its end faces. The sealant receptacle 41 extends in the manner of a groove along the end face of the intermediate ring 40.
- a seal consisting of a rubber-elastic material can be accommodated to the interior of the Housing wall 102 ge compared to the area of the viewing window 1 or the viewing opening 2 th.
- the air and climatic conditions prevailing inside the housing wall 102 therefore do not transfer into the interior of the viewing window 1.
- the risk of undesired fogging of the viewing window 1 becomes clear decreased.
- a third function of the intermediate ring 40 is that it consists of an optically non-transparent material and in this respect forms a screen. It is therefore not possible for the observer to look over the window panes 11, 12 into the area between the two plate-shaped elements 103 at the filler arranged there.
- the Fastening sections 9, 10 of the disk carriers 3, 4 can therefore be designed to be transparent, advantageously with a frosted glass-like surface. Details of the locking device 31 will now be explained with reference to the Dar positions in FIGS. 18 to 23.
- FIG. 18 shows a perspective view of the disk carrier 3.
- a locking element 32 is provided on the fastening means 5, projecting radially inwards.
- the locking element 32 is formed out in the manner of a locking lug and interacts when generating the rotary connection 30 with the locking elements 33 provided on the other disk carrier 4.
- the locking elements 33 of the other disk carrier 4 can be seen in FIGS. 19 and 20.
- the fastening means 6 which is formed by several spiral spiral sections 6.1, 6.2, 6.3, a large number of latching elements 33 can be seen.
- the locking elements 33 are arranged parallel to the spiral coil sections 6.1, 6.2, 6.3.
- Each of the spiral spiral sections 6.1, 6.2, 6.3 is assigned a detent section 34 formed from a plurality of detent elements 33 arranged in a row, on which the detent element 32 engages when the rotary connection 30 is made by engaging the fastening means 5 on the fastening means 6.
- the latching element 32 When the disk carriers 3, 4 are rotated relative to one another, the latching element 32 is moved along one of the latching sections 34 in a manner similar to a ratchet and latched between two latching elements 33 as soon as the rotary movement ends. As a result, a detent 31 is formed, which prevents an unintentional turning back, for example, due to vibrations acting on the viewing window 1, over time porous seals or similar conditions.
- the rotary connection 30 is functionally coupled to the locking device 31.
- the locking device 31 is also automatically activated when the rotary connection 30 is established.
- the fastening section 9 of the disk carrier 3 temporarily extends and then snaps back into its original position due to the inherent elasticity of the material.
- 3 corresponding force introduction points 35 are provided on the disk carrier.
- the force introduction points 35 are formed in the manner of key surfaces.
- the force introduction points 35 can be gripped with a special tool and the disk carrier 3 can be turned with a sufficiently large tightening torque.
- a guideway 34 formed from a multiplicity of latching elements 33 is arranged parallel to a fastening means 6 or one of its spiral spiral sections.
- the locking elements 33 have a wavy contour with th between the locking elements 33 angeordne recesses 36, in which the locking element 32 can gelan conditions for contact.
- the locking elements 33 or recesses 36 each have a locking distance A along the locking distance 34, which results in a uniform locking in the manner of a ratchet.
- the ras tiata 33 also have a serrated, scale-like or barbed structure.
- the rotary movements of the two disk carriers 3, 4 can also end in a position in which the latching element 32 lies on top of a latching element 33.
- the disk carrier 3 will be rotated back a maximum of half a latching distance A until the latching element 32 has entered the closest recess 36 and has latched between two adjacent latching elements 33.
- the council distance A and the slope of the spiral spiral sections 6.1, 6.2, 6.3 are dimensioned such that the resulting axial movement of the disk carriers 3, 4 is negligibly small. In particular, there is no fear that the existing seals will lose their effectiveness.
- the viewing window 1 has on the outside of a cover-like cover 52 which is articulated on a pivot bearing 53 via a hinge joint 55.
- the viewing window 1 is closed opaque via the cover 52, cf. also the illustration in FIG. 17.
- the structure of the viewing window 1 is shown in a perspective view in FIG. 25 and essentially corresponds to the configurations described above.
- the lighting element 50 is provided on the inside of the viewing window 1.
- the light-emitting element 50 is, as was already clear from the illustration in FIGS. 16 and 17, in the region of the window frame 8 the disc carrier 4 arranged.
- the window frame 8 has an on groove 20, in which the lighting element 50 is housed.
- the window frame 8 consists of an optically transparent material, so that the lighting element 50 can illuminate the observation area inside.
- a separate switch can be provided to actuate the lighting element 50.
- the cover 52 is operatively connected to the lighting element 50 such that the lighting element 50 is automatically switched on when the cover 52 is opened.
- the lighting element 50 is automatically switched off. In this way, it is prevented that with the cover 52 closed, for example due to an operating error, there is the possibility that the lighting element 50 continues to light unobserved.
- a power supply 54 is provided, which is designed in the manner of a battery box.
- the power supply 54 is integrated in the pivot bearing 53, which results in a compact design.
- the battery case 54 or the pivot bearing 53 need only be fastened to the outside of the housing wall 102 via two screw connection points 56.
- the light element 50 is constructed as an LED ring with a plurality of light points 57, which are arranged evenly distributed over the circumference of the light element 50.
- the luminous dots 57 each have an angular distance a from one another.
- the arrangement of the lighting element 50 in the area of the window frame 7 does not impair the available viewing area of the viewing window 1.
- the Luminous element 50 can also be used independently of external power supplies at a suitable location due to the power supply 54 integrated into the viewing window 1.
