Description

[Detailed description of the invention] The present invention is a support device for a cover that is rotatably arranged on a casing, and includes a support member formed only on the casing and the cover, and the support member is provided on the cover. It relates to a type in which the bearing member is brought into active position by a radial connection with respect to the pivot axis.

In the case of housings with a cover or flap that can be pivoted open, as is known, the outer hinge element or bearing element can be moved in particular to the front side of the housing by means of a bearing shaft or bearing pin. The aesthetic impression of the casing is spoiled if the hinge element or the bearing element is arranged outside the casing cross section, i.e. at the edge of the casing or outside the basic body consisting of the casing and the cover. If a large number of such base bodies were to be arranged closely side by side, the hinge or bearing members would create assembly problems, and the front face of the cover would be located approximately in the assembly plane, or the cover would be placed only slightly in the assembly plane. It is desirable that the arrangement be such that it protrudes from the top. For example, it is necessary to provide special cutouts on the basis of the externally located bearing elements or there are differences in the installation plane in relation to the distance between the installation plane and the plane in which the pivot axis of the cover is located in the installed state of the casing. In order to avoid the above-mentioned installation problem of having to provide a large swivel gap and to take appropriate concealment measures accordingly, and to obtain a casing that can be installed in a flexible and simple manner,
providing a pivot axis of the cover within the casing;
That is, it is necessary that the pivot axis be located within a plane parallel to the front surface of the cover within the limited plane between the casing and the cover.

For aesthetic reasons, a casing with a planar front face is desired, which means that if the bearing elements are located on the inside, they are more or less smaller than the casing cross-section and are arranged, as it were, embedded in the casing. Starting from the fact that the cover is provided with a casing extension whose front face is located in the plane of the front face of the cover, it can be seen that in this type of construction the swivel gear problem is transferred to the casing and that the casing It must be accepted that the front surface of the front surface is divided by a seam that detracts from the aesthetic appearance of the structure and creates significant sealing problems.

It is self-evident that if, on the one hand, a swiveling gap as narrow as possible between cover and casing and, on the other hand, a maximum possible swivel angle of the cover is desired, then this requirement can be met, for example, by using so-called lever-type bearings for the cover. This can be achieved by using a hinge member. However, the above-mentioned sealing problem cannot be solved by the bearing device, which causes the cover to be lifted off the casing when pivoted. On the contrary, the use of the bearing device creates the risk that, when the cover is opened, dirt and dust located on the cover will fall into the housing. Sometimes these solutions require relatively high component costs and relatively large space requirements, as well as considerable manufacturing and adjustment costs.

On the other hand, for the above-mentioned problems, a connection by a membrane hinge element is almost an ideal solution; ,
Particularly if the cover in question no longer has a negligible weight and does not have only a cover function, the guiding precision and the holding force in the closed position are insufficient and the frequency of operation It cannot be used because of the limited service life.

The invention therefore proceeds from the recognition that by making the distance between the front face of the cover and the pivot axis of the cover as small as possible, a narrow swing gap and a swing angle as large as possible can be obtained in principle. The object is to create a design of the type mentioned at the outset, in which the disadvantages of the known solutions are avoided, and which, in particular, provides satisfactory guiding precision and an adequate sealing effect, and which, due to its simple construction, allows problem-free manufacture and assembly. The object of the present invention is to provide a support device for a cover of a casing which can be installed in the same plane as the casing.

According to the invention, the object is achieved by providing at least one bearing shell which is open outwardly with respect to the interior of the casing, the geometrical axis of which is formed by the cover and the casing. is formed in the casing so as to pass through the base body,
A substantially cylindrical tongue having an outer diameter corresponding to the inner radius of the bearing shell fixed to the casing is integrally molded on the first component of the cover, and on the second component of the cover, At least one further bearing shell is formed with an inner radius corresponding to the outer radius of the bearing shell fixed to the casing, and both components of the cover are associated with the bearing shell fixed to the casing. The tongue strip, the bearing shell body fixed to the casing, and the bearing shell body fixed to the cover can be coupled to each other so that they are arranged coaxially, and furthermore, both the bearing shell bodies and the tongue strip This problem has been solved by at least one of the following extending over the entire opening width of the casing.

Furthermore, the cover is formed with a bearing shell body that is open toward the front side of the cover, and the tongue strip assigned to the bearing shell body is integrally molded on the casing, and the cover is further formed with a component that can be connected to the casing. At least one bearing shell surrounding the fixed bearing shell can be provided.

According to a further advantageous embodiment, at least one projection, which is attached to the edge of the shell and projects approximately radially into the shell opening, is integrally formed on the bearing shell, which is fastened to the housing; An undercut is formed between the base and the bottom of the shell body, and a recess, which is assigned to the projection, and a web corresponding to the cross-sectional shape of the undercut are formed in the tongue.

The bearing device according to the invention avoids the disadvantages of lever-type hinges and membrane-like hinges, without neglecting particularly important points, namely that the dust-proofing effect and the appearance are achieved in an satisfactory manner. Advantageously, the bearing element can be formed directly in the components that are operatively connected to one another, namely the cover and the casing, and the bearing device can also be formed without additional elements and without additional assembly, such as drilling or pinning. It can be completed without any further processing, ie it has special suitability for mass production. In this case, although the guiding accuracy, load-bearing capacity and torsional stability are sufficient, the space required is extremely small and, moreover, the swivel gear appears only as a line, which limits the aesthetic design. It will not be done.

Furthermore, it is advantageous that the sealing effect of the selected cylinder/shell bearing arrangement can be achieved without the use of additional sealing elements and is also maintained with respect to falling dust when the cover is opened. Furthermore, the bearing device according to the invention, which allows for a spatially compact housing construction, can also be used with various housing shapes, for example rectangular or cylindrical housing shapes, and is not necessarily used in the case of built-in housings. It's not something you can do. Thus, for example, the cover of the housing can be designed in the form of a trough, and the bearing device according to the invention can, in the extreme, be provided for two housing halves that are pivotally connected to one another.

The invention will now be described with reference to the illustrated embodiment.

FIG. 1A shows a front view of the casing 1 with the cover 2 closed, FIG. 1B shows a side view of the casing 1 with the cover 2 open, and FIG.
The figure shows a side view of the casing 1 with the cover 2 closed. In selected embodiments the cover 2 is lockable with the casing 1 via the lock 3
is formed by a frame 4 with a fitted window pane 5 (in this embodiment the cover consists of two parts, in which case the window glass does not necessarily have to be provided) and a casing and a cover. It is pivotally connected to the casing 1 via a bearing device according to the invention, which is located inside with respect to the base body consisting of. When the cover 2 is closed as shown, the front surface 6 of the cover 2 and the front surface 7 of the casing addition part 8 formed on the casing 1 are located in the same plane. A planar arrangement of the surfaces 9 and front faces 6, 7 of switchboards, instrument panels and the like is obtained in a suitable manner without having to hold them in place. Reference numeral 10 designates the required pivot gap between the cover 2 and the casing extension 8.

As shown in detail in the perspective view of FIG.
1 extends from one housing wall 12 towards a parallel housing wall, not shown. A cylindrical tongue 13 is therefore formed on the frame 4 of the cover 2, which is assigned to the bearing shell 11. In this case, the length of the tongue 13 corresponds at least to the length of the bearing shell 11, while the outer diameter of the tongue 13 corresponds to the inner radius of the bearing shell. Furthermore, as is clear from FIG. 2, the bearing shell 14, one of the two bearing shells formed on the window pane 5, surrounds the bearing shell 11. The outer radius of the bearing shell 11 thus corresponds to the inner radius of the bearing shell 14. Therefore, if the window pane 5 is connected to the frame 4, for example by means of suitable locking elements (not shown), the tongue strip 1 will close when the cover 2 is pivoted.
3 rolls within the bearing shell 11, and at the same time the bearing shell 14 slides on the bearing shell 11.
Support members 11, 13, 14 operatively connected to each other
A shape-connective connection is obtained. Stops 15, 16, which are formed on the bearing shell 11 on the one hand and on the respective bearing shell 14 on the other hand, are used in this case to limit the pivot angle or opening angle of the cover 2.

As is clear from FIGS. 3 and 4, the bearing device according to the invention has a very small spacing of 1 mm between the pivot axis of the cover 2 and the common front face 6, 7 of the cover 2 and the casing 1. a and thus a relatively small swing gear 1
A sufficiently large turning angle can be obtained at 0. In order to accommodate the bearing play caused by tolerances, the axis of the bearing shell 14 can be made slightly eccentric and the bearing shell itself spring-elastic, so that the bearing shell 14 is It surrounds the body 11 in a spring-elastic manner. Furthermore, cover 2
If the cover 2 functions as a table or a desk at the pivot angle position, that is, if a relatively large force is expected to be applied to the limit stopper, a locking member may be provided, for example. The locking element is pivoted on the cover on the one hand and is displaceably mounted in a guide groove provided in the housing wall 12 on the other hand. Furthermore, the cover 2 is attached to the frame 4 in the closed position of the cover.
Seal 18 by wide edge 17 formed in
is inserted into contact with the casing 1 or with an end face of the casing wall 12, which is not shown in detail.

FIG. 5 shows a variant embodiment of the previously described arrangement of the bearing parts 11, 13, 14, in which case the bearing shell 19 corresponding to the bearing shell 14 is connected to the base 20, which can be connected to the housing 1. It is integrally molded into. In this case, such a joint is
In order to be able to compensate for bearing play in a simple manner, it can be configured to be adjustable. In such a reverse arrangement, the tongue strip 13
A corresponding tongue 21 is arranged on the housing extension 8, whereas a bearing shell 22 corresponding to the bearing shell 11 is molded directly onto the cover 23 using an injection molding technique. In the case of this variant, there is also a separating seam or pivoting gap 10.
appears only as a line, so that the cylindrical/shell bearing device according to the invention produces an extremely good external impression and provides an effective dust-retaining action without the use of additional sealing elements. can get.

Furthermore, the bearing device according to the invention can also be arranged on one side wall of the casing, if the casing is not designed in such a way that the front surfaces can be installed in the same plane.

Advantageously, the housing 1 has a removable bottom, so that it can be produced without difficulty using injection molding techniques. Furthermore, the casing attachment part 8
A configuration is also possible in which the housing 1 can be manufactured as a separate component that can be connected to the housing 1.

However, the bearing device according to the invention is based partly on the lack of space in the embodiments described so far and partly on the basis of the reduction in wall thickness as desired in the injection molding technical construction of the component. However, on the other hand, in order to compensate for the bearing play due to tolerances, a single piece formed on the cover, which surrounds the bearing shell 11, which is fixed to the housing, for example. Alternatively, a certain degree of spring elasticity is desired for the shell bodies 14, so that reinforcement by suitable ribbing is meaningless, i.e. especially for bearing shell bodies whose cover is relatively wide open and which is fixed to the casing. If the degree of overlap between 11 and the bearing shell body 14 fixed to the cover is small, it is possible to easily close the cover 2 to the bearing shell body 14 fixed to the casing 1 without destroying the bearing members 11, 13, 14. There is a risk that it can be pulled out of the holding part in the body 11.

Such a defect, which has the possibility of making the device inoperable under the guise of a manufacturing error, is caused by the use of recording devices whose records have the characteristics of documentary evidence and are at risk of being tampered with. It cannot be ignored especially in cases.

Therefore, in order to make separation and reconnection of the support members 11, 13, 14 difficult, at least the separation of the cover 2 and the casing 1 is made difficult by the support members 11, 13, 14.
13, 14, as can be seen from FIGS. 7 and 8, in an advantageous embodiment of the invention, the bearing shell 11 fixed to the housing is A web 26, which is formed in the tongue strip 13 by means of a suitable recess 25, is assigned to the integrally formed projection 24. In this case, the projection 24 is arranged on the edge of the bearing shell 11, which is fixed to the housing, and projects radially into the shell opening. Reference numeral 27 forms a release slot required in the injection molding technical production of the projection 24, while reference numeral 28 forms the part between the shell bottom of the bearing shell 11 fixed to the housing and the projection. 24 is shown, and the web 26 protrudes into the undercut portion when the cover 2 is opened. The described safety devices are preferably provided in several mutually spaced locations of the bearing, for example assigned to a bearing shell fixed to the cover and of the same type on the cylindrical-shell bearing. The modified embodiment shown in FIG. 5 can also be formed.

In the contrasting cross-sectional views, namely FIGS. 6 and 7, on the one hand the bearing shell 1 is fixed to the cover;
4 and the bearing shell 11 which is fixed to the casing in a relatively dangerous intermediate position which results in only a slight overlap between the bearing shell 11 and the bearing shell 11 which is fixed to the casing, for example by the action of a suitable force in the direction of the arrow shown in FIG. how the bearing shell 14 is elastically deformed and how the tongue strip 13 disengages from the seat fastened to the housing, and on the other hand the said intermediate position of the projection 24 and the housing 2. It is illustrated how the web 26 already engaged within the undercut portion 28 acts against disengagement. In this case, the safety device does not interfere with the operation of the cover, either in the closed or open state, and does not cause any drawbacks with respect to the swivel angle or the swivel gap, so that the appearance of the instrument is It is clear that no disadvantages arise.
