Description

[0001] The invention relates to an adjustment unit for an operating terminal, an operating terminal for an environmental simulation chamber, and an environmental simulation chamber.

[0002] Environmental simulation chambers are used in many areas of science and engineering to simulate specific climatic conditions. Input and / or output for controlling such a chamber is typically achieved via an operator terminal located on the outside of the chamber. This terminal typically features a screen and / or buttons for exchanging information between the user and the chamber.

[0003] To achieve the best possible usability, and especially readability, of the operating terminal, it is state of the art to mount the operating terminal at an angle depending on boundary conditions, such as the location of the environmental simulation chamber or the height of the users. Such an arrangement is described, for example, in WO 2004 062 157 A2. To adapt the display of a device to changing boundary conditions, it is also known, for example, from EP 3 935 331 B1, DE 10 2005 063 090 A1, or DE 100 54 912 A1, to design the display to be adjustable. US 2001 0 052 741 A1 further discloses an arrangement in which detent positions are provided at different angles of inclination.

[0004] A disadvantage of the known solutions is that the displays either cannot be locked in place at all, or can be disengaged from their locking position simply by applying pressure to the display. Therefore, these solutions are unsuitable for industrial applications, particularly in environmental simulation chambers where the operating terminals are subject to frequent use and users sometimes wear protective clothing.

[0005] The invention is therefore based on the objective of providing a device with which an operating terminal can be arranged at an angle on a device, such that the arrangement is robust, easy to handle, and has a long service life. The invention is further based on the objective of providing an operating terminal with such a device, as well as an environmental simulation chamber with a corresponding operating terminal.

[0006] The problems are solved according to the invention by an adjustment unit with the features of claim 1, an operating terminal with the features of claim 14 and an environmental simulation chamber with the features of claim 15.

[0007] Advantageous embodiments and further developments of the invention are specified in the dependent claims.

[0008] An adjustment unit according to the invention for an operating terminal comprises a first folding element, a second folding element, a pivot axis about which the first folding element and the second folding element are rotatable relative to each other, a locking element arranged on the first folding element and having at least one locking recess, and a support element arranged on the second folding element and arrangable in one of the at least one locking recess. By arranging the support element in the at least one locking recess, the support element can be supported in the at least one locking recess. The support element can be rotatably arranged on the second folding element.

[0009] The adjustment unit according to the invention has a slider that is displaceable along a sliding axis. The slider can be arranged in a first position such that the at least one detent recess for the support element is open, and in a second position such that the at least one detent recess for the support element is locked. This arrangement allows the at least one detent recess to be opened or closed for the support element. This provides a robust adjustment unit for an operating terminal. The slider can be displaced from the first position to the second position and vice versa along the sliding axis. In the first position, the slider is preferably arranged such that the support element can be inserted into the at least one detent recess.In the second position, the slider is preferably arranged such that the support element cannot be inserted into the at least one locking recess.

[0010] In a preferred embodiment of the invention, the slide has a first drive projection and a second drive projection arranged opposite the first drive projection with respect to the sliding axis. The support element for moving the slide from the second position to the first position can be arranged on the first drive projection, and / or the support element for moving the slide from the first position to the second position can be arranged on the second drive projection. In this way, the slide can be moved by means of the support element. In particular, a rotational movement of the two hinge elements relative to each other about the axis of rotation can thus cause the slide to move along the sliding axis.

[0011] Preferably, the slide has a base body with a C-shaped recess, wherein the first and second drive projections are each formed by a recess end. This allows the support element to be moved within the recess from the second drive projection to the first drive projection.

[0012] The slide can have at least one slide recess, wherein in the first position the at least one locking recess and the at least one slide recess are preferably aligned with each other. Preferably, the at least one locking recess and the at least one slide recess are aligned when viewed transversely to the sliding axis. In this way, the at least one locking recess can be open for the arrangement of the support element within the at least one locking recess. Thus, in the first position of the slide, the support element can be arranged simultaneously in the at least one locking recess and the at least one slide recess. Preferably, the number of at least one slide recess corresponds to the number of at least one locking recess.The locking element preferably has three locking recesses arranged one behind the other along the sliding axis, each of which can include the features of at least one locking recess. This allows the first and second folding elements to be locked in three different positions relative to each other. The locking recesses are preferably identical. The sliding recesses can also be identical.

[0013] The at least one sliding recess is preferably arranged between the first and second drive projections with respect to the sliding axis. The at least one sliding recess can, in particular, be arranged in the C-shaped recess.

[0014] Each of the at least one detent recess can have a detent recess contour with a first end section and a second end section, wherein the first end section is arranged perpendicular to the sliding axis and / or the second end section is arranged obliquely to the sliding axis. With a plurality of detent recesses arranged one behind the other along the sliding axis, the slider can thus have a sawtooth contour arranged along the sliding axis. By arranging the first end section perpendicular to the sliding axis, the support element can be supported at the first end section of the at least one detent recess. By arranging the second end section obliquely to the sliding axis, the support element can slide out of the at least one detent recess at the second end section of the at least one detent recess.

[0015] The at least one sliding recess can have a sliding recess contour that is geometrically similar, at least in sections, to the locking recess contour. In particular, the sliding recess contour can be designed to be centrally extended relative to the locking recess contour, so that in the first position of the slide, the at least one sliding recess is offset from the at least one locking recess contour. This allows for defined support of the support element in the locking recess. The sliding recess contour can have a first end section, corresponding to the locking recess contour, which is shorter than the first end section of the locking recess contour. This prevents the support element from jamming.

[0016] The at least one locking recess is preferably arranged such that the first end section is oriented towards the first drive projection and the second end section towards the second drive projection. Thus, the first end section of the locking recess contour is preferably positioned closer to the first drive projection than the second end section of the locking recess contour.

[0017] The locking element preferably comprises a first locking element part, a second locking element part, and a sliding groove extending between the first locking element part and the second locking element part along the sliding axis, in which the slider is arranged. Each of the at least one locking recess is preferably arranged in the first locking element part and in the second locking element part, such that each of the at least one locking recess preferably intersects the sliding groove.

[0018] In a further development of the invention, the detent element and / or the slide has locking means for increasing the friction between the detent element and the slide. This prevents the slide from shifting in situations where the support element is not arranged in the at least one detent recess or the at least one slide recess.

[0019] Preferably, the locking means are designed as locking projections arranged on the slide and / or the locking element. The locking means can be arranged, in particular, on a rear surface of the slide opposite the recess and / or on a side surface of the slide arranged laterally to the recess. It is also conceivable to arrange the locking means in the sliding groove.

[0020] In a preferred embodiment of the invention, the adjusting unit has a retainer, preferably designed as a leaf spring, for guiding the support element. This allows the support element to be held in the recess for moving the slide. Furthermore, in the first position, the support element can be engaged in the at least one detent recess. The retainer can be U-shaped and / or arranged at least partially within the recess.

[0021] An air gap can be arranged between the slide and the hold-down device. This allows the sliding force required to move the slide to be set independently of the detent force required to disengage the support element from the at least one detent recess. The support element is preferably designed as a bracket arranged between the hold-down device and the slide.

[0022] An operating terminal according to the invention, particularly for an environmental simulation chamber, comprises the adjustment unit described above, wherein the first folding element is designed as an operating part and the second folding element as a base part of the operating terminal. The operating part preferably includes an input and / or output unit for inputting and / or outputting information or commands. The base part can, for example, be designed for mounting the operating terminal on the environmental simulation chamber or as part of the environmental simulation chamber itself. The operating terminal can thus be mounted at an angle on an environmental simulation chamber.

[0023] An environmental simulation chamber according to the invention has the operating terminal described above.

[0024] An embodiment of the invention is explained with reference to the following figures. It shows: Fig. 1 a perspective view of an exemplary embodiment of an operator terminal with detail A marked, Fig. 2 a detailed view of the in Fig. 1 marked details A, Fig. 3 a perspective view of the in Fig. 1 shown embodiment with hidden hold-down and marked detail B, Fig. 4 a detailed view of the in Fig. 2 marked details B, Fig. 5 a sectional view of the in Fig. 1. Exemplary embodiment shown in a first position with marked detail C, Fig. 6 a detailed view of the in Fig. 5 marked details C, Fig. 7 a sectional view of the in Fig. 1. Exemplary embodiment shown in a second position with marked detail D, Fig. 8 a detailed view of the in Fig. 7 marked details D, Fig. 9 a sectional view of the in Fig. 1 shown embodiment in a third position with marked detail E, Fig. 10 a detailed view of the in Fig. 9 marked details E, Fig. 11 a perspective view of the slider of the in Fig. 1 shown embodiment, Fig. 12 an exploded view of the in Fig. 1 shown embodiment, Fig. 13 a perspective view of a first embodiment of an environmental simulation chamber, Fig. 14 a perspective view of a second embodiment of an environmental simulation chamber.

[0025] The Fig. Figures 1 to 14 show different embodiments. The same reference numerals are used for identical and functionally equivalent parts. For clarity, not all reference numerals are used in every figure.

[0026] Fig. Figure 1 shows a perspective view of an operating terminal 10 for an environmental simulation chamber 12 with an adjustment unit 14. The adjustment unit 14 comprises a first folding element 18 designed as an operating part 16 and a second folding element 22 designed as a base part 20. In the Fig. Figures 13 and 14 show the control unit 16 from the front. It can be seen that the control unit can include an input and / or output unit 24 for inputting and / or outputting information or commands. The figures also show... Fig. Figures 13 and 14 state that the base part 20 can be designed to accommodate the operating terminal 10 on the environmental simulation chamber 12. The operating terminal 10 can thus be inclined on the environmental simulation chamber 12 by means of the adjustment unit 14.

[0027] The representation in Fig. Figures 1 and 2 show that the adjusting unit 14 comprises a pivot axis 26 about which the control element 16 and the base part 20 can be rotated relative to each other. The adjusting unit 14 preferably further comprises a locking element 30 arranged on the control element 16 and having several locking recesses 28, as well as a support element 32 arranged on the base part 20 and which can be positioned in each of the locking recesses 28. By arranging the support element 32 in one of the locking recesses 28, the support element 32 can be supported in the respective locking recess 28. The support element 32 can be rotatably arranged on the base part 20 about a support element axis 34.

[0028] As the Fig. As shown in Figures 1 and 2, the adjusting unit 14 can have a retainer 38 designed as a leaf spring 36. The retainer 38 can, in particular, be arranged on the detent element 30.

[0029] The Fig. Figures 3 and 4 show the Fig. Figures 1 and 2 show corresponding illustrations in which the hold-down device 38 is hidden for clarity. The adjusting unit 14 has a slide 40, which is particularly important in Fig. 4 is recognizable. In the Fig. Figures 5-10 show the operating terminal 10 in different positions. It can be seen that the slide 40 can be arranged in a first position such that the locking recesses 28 are open for the arrangement of the support element, allowing the support element 32 to be inserted into one of the locking recesses 28 ( Fig. 5-6 and 9-10). In Fig. Figures 7 and 8 show the operating terminal 10 in a position in which the slide 40 is arranged in a second position such that the detent recesses 28 for the arrangement of the support element 32 are locked, so that the support element 32 preferably cannot be inserted into any of the detent recesses 28. The slide 40 can be displaced from the first position to the second position and vice versa along a sliding axis 42.

[0030] How in particular the Fig. As shown in Figure 4, the locking element 30 can have a first locking element part 44, a second locking element part 46, and a sliding groove 48 extending between the first locking element part 44 and the second locking element part 46 along the sliding axis 42. The slider 40 is preferably arranged in the sliding groove 48. The locking recesses 28 are preferably arranged in the first locking element part 44 and in the second locking element part 46 such that each locking recess 28 intersects the sliding groove 48 at a right angle.

[0031] A detailed view of slide 40 is in Fig. 11 shown. Fig. Figure 11 shows that the slide 40 preferably has a first drive projection 50 and a second drive projection 52 arranged opposite the first drive projection 50 with respect to the sliding axis 42. Preferably, the support element 32 for moving the slide 40 from the second position to the first position can be arranged on the first drive projection 50, and the support element 32 for moving the slide 40 from the first position to the second position can be arranged on the second drive projection 52. In this way, the slide 40 can be moved by means of the support element 32.

[0032] The Fig. Figure 11 shows that the slide 40 can have a base body 54 with a C-shaped recess 56, wherein the first drive projection 50 and the second drive projection 52 are each formed by a recess end 58 of the recess 56. Thus, the support element 32 can be moved in the recess 56 from the second drive projection 52 to the first drive projection 50.

[0033] Fig. Figure 11 further shows that the slide 40 can have three slide recesses 60. The number of slide recesses 60 preferably corresponds to the number of detent recesses 28. In the Fig. In the first position shown in Figures 5-6 and 9-10, the locking recesses 28 and the sliding recesses 60 are preferably arranged in alignment with each other, so that in the views shown there, transverse to the sliding axis 42, the locking recesses 28 and the sliding recesses 60 are in the same plane. Thus, the locking recesses 28 are open for the arrangement of the support element 32, so that, as shown in the Fig. As shown in Figures 5 and 6, the support element 32 can be arranged simultaneously in one of the locking recesses 28 and one of the sliding recesses 60. A corresponding arrangement is also shown in Figures 5 and 6. Fig. 1-4. The sliding recesses 60 are preferably arranged between the first drive projection 50 and the second drive projection 52 in the C-shaped recess 56 with respect to the sliding axis 42. By providing three detent recesses 28 and three sliding recesses 60, the operating element 16 and the base element 20 can be locked in three different positions relative to each other.

[0034] The representation in Fig. Figure 6 illustrates that each of the detent recesses 28 can have a detent recess contour 62 with a first end section 64 and a second end section 66, wherein preferably the first end section 64 is arranged perpendicular to the sliding axis 42 and the second end section 66 is arranged obliquely to the sliding axis 42. Due to the plurality of detent recesses 28 being arranged one behind the other along the sliding axis 42, the slider 40 can thus have a sawtooth contour arranged along the sliding axis 42. As can be seen from the Fig. As can be clearly seen in Figure 5, the support element 32 can be supported on the first end section 64 by arranging the first end section 64 perpendicular to the sliding axis 42. By arranging the second end section 66 at an angle to the sliding axis 42, the support element 32 can slide out of the respective locking recess 28 on the second end section 66.

[0035] The view in Fig. Figure 11 shows that the sliding recesses 60 each have a sliding recess contour 68. The sliding recess contour 68 is geometrically similar, at least in sections, to the locking recess contour 62. The sliding recess contour 68 can, in particular, be centrally extended relative to the locking recess contour 62, such that in the Fig. In the first position of the slide 40 shown in Figures 5 and 6, each of the slide recesses 60 is set back relative to the corresponding detent recess contour 62. The slide recess contour 68 can have a first end section 70 and a second end section 72 corresponding to the detent recess contour 62, the first end section 70 being shorter than the first end section 64 of the detent recess contour 62. This prevents the support element 32 from jamming. The detent recesses 28 are preferably arranged such that the first end section 70 faces the first drive projection 50 and the second end section 72 faces the second drive projection 52.

[0036] Especially in the presentation of the Fig. 1 and 2 as well as in the detailed view of the Fig. 6, Fig. Figures 8 and 10 show the hold-down device 38 for guiding the support element 32. Preferably, the hold-down device 38 is arranged such that, starting from the point in Fig. In the position shown in Figure 6, the slide 40 must be lifted by the support element 32 to move it. The support element 32 can be held in the C-shaped recess 56 for moving the slide 40 by means of the hold-down device 38. Furthermore, in the first position of the slide 40, the support element can be engaged in one of the detent recesses 28 due to the presence of the hold-down device 38. As shown in particular in the sectional views of the Fig. 6, Fig. As shown in Figures 8 and 10, the hold-down device 38 can be U-shaped and arranged at least partially in the recess 56. These figures also clearly show that the hold-down device 38 is attached to the locking element 30 at one end of the sliding groove 48 by means of a screw connection. An air gap 74 can be arranged between the slide 40 and the hold-down device 38. The support element 32 is preferably designed as a bracket arranged between the hold-down device 38 and the slide 40 (see in particular Figure 8). Fig. 1 and 2).

[0037] Based on the in the Fig. The basic operating principle of the adjustment unit 14 can also be explained by the positions shown in Figures 5 to 10. This is based on the assumption that the base part 20 is fixed in space. In the positions shown in the Fig. In the position shown in Figures 5 and 6, the slide 40 is in the first position and the support element 32 is arranged in the uppermost of the detent recesses 28, so that a folding angle 76 of greater than 0°, preferably approximately 60°, is arranged between the operating part 16 and the base part 20. By manually lifting the operating part 16 such that the folding angle 76 is further increased, the support element 32 can be disengaged from the detent recess 28 against the resistance of the retainer 38 and placed against the second drive projection 52.

[0038] By further increasing the folding angle 76, preferably to greater than or equal to 90°, by further raising the operating element, the slider 40 can be moved along the sliding axis 42 into the second position. The corresponding position of the adjusting unit 14 is shown in the Fig. Figures 7 and 8 show that by positioning the slider 40 in the second position, the locking recesses 28 are locked by the slider 40. This allows the operating element 16 to be subsequently folded down, thus reducing the folding angle 76, whereby the support element 76 is moved along the C-shaped recess 56 of the slider 40 without the support element 32 being positioned in one of the locking recesses 28.

[0039] Before the folding angle 76 reaches a value of 0° when the control element 16 is folded down, the support element 32 reaches the first engagement projection 50. A further folding down of the control element 16 ensures that the slider 40 is returned to its first position by the support element 32 along the sliding axis 42, so that the detent recesses 28 are open (see Fig. 9 and 10). By subsequently lifting the control unit 16, the support element 32 can be positioned in one of the locking recesses and the control unit 16 can thus be adjusted.

[0040] To prevent unintentional displacement of the slide 40, for example when the support element 32 moves along the locked detent recesses 28, the slide 40 can, in particular, have locking elements 80 designed as locking projections 78 to increase the friction between the detent element 30 and the slide 40. As shown in the illustration of the slide 40 in Fig. As shown in Figure 11, the locking projections can be arranged in particular on a rear side 82 of the slide 40 opposite the recess 56 and on a side surface 84 of the slide 40 arranged laterally to the recess 56.

[0041] The Fig.Figures 13 and 14 each show an embodiment of the environmental simulation chamber 12, wherein the operating terminal 10 is arranged on the outside of a door 86 of the environmental simulation chamber 10. It can be seen that the base part 20 is directly adjacent to the door 86.
