Of the Basic body is according to a preferred Variant in particular designed so that he is able to Board or carrier plate of an electronic circuit take shape, friction, force or material fit. Of the Basic body can be on its inside elements, in particular Grooves or longitudinal guides, for holding the board or carrier plate.

The Invention enables the realization of a design concept for a housing made of plastic profiles and allowed a compact design with simple installation.

Of the Closure preferably acts as a seal against penetration of dust and water in the case. The housing is preferably one for a mechanical, electrical or optical device. The closure is preferably a single part and is preferably made as a profile.

Brief description of the drawing, in which schematically and exemplarily shows:

1 a perspective view of a portion of a housing according to the invention according to a preferred embodiment of the invention.

This in 1 illustrated housing G consists of three each one-piece parts, namely a body 30 , a cover 40 and a closure 10 ,

The housing G extends in a longitudinal direction L between two end faces S1, S2. The main body G extends in the longitudinal direction L from one to the other end face and is open on a side surface F and at least one of the end faces S1. In the present example, the main body G is substantially a V-profile, which preferably consists of aluminum; According to another variant, the V-profile is produced by extrusion of plastic. Between the free longitudinal end edges of the legs of the V-profile 30 is the open area F.

Also the cover 40 runs from the front side S1 to the front side S2, but is in 1 shortened to the view into the interior of the main body 30 feizugeben.

The housing G has at least one elastic closure 10 on which so in the body 30 einbringbar or insertable is that the closure 10 in the main body 30 assumes a closed position, in which the closure in the longitudinal direction L is not above the main body 30 survives, stable in the body 30 is held under mechanical pressure, which by elastic deformation, namely compression, the elastic closure 10 conditionally, on the inner wall 50 of the basic body 30 is applied. Here, the open end S1 of the main body 30 through the lock 10 covered.

1 shows the closure 10 in closed position.

The housing also has a cover 40 on, which in the longitudinal direction L of the housing G so on the body 30 pushed on and thereby with respect to the basic body 30 can be brought into a covering position, in which the cover 40 the open lateral area F of the main body 30 covering between the end faces S1, S2.

In addition, the cover 40 also by pressing the same on the body 30 transverse to the longitudinal direction L with the main body 30 latched and thereby also in the covering position be brought.

The Cover is in the covering position against movement across Longitudinally by positive engagement and against movement in the longitudinal direction by frictional, force or material connection held the body and non-destructive both again removed from the covering position and from the body removable again.

In 1 is the cover 40 only partially shown to look into the interior of the main body 30 to enable.

The cover 40 lies in the main body 30 introduced or inserted, located in the closed position closure 10 with its inner wall 60 under mechanical pressure, which also by elastic deformation, ie compression, of the elastic closure 10 is conditional on the closure 10 at. The closure closes when befindlicher in cover position cover 40 the front wall S1 water and dustproof, the sealing effect by the elasticity of the closure 10 and due to the fact that the extent of the closure 10 in the relaxed state in each direction perpendicular to the longitudinal axis L is slightly larger that is the clear width of the housing interior in this direction, so that in the body 30 introduced or inserted closure 10 with cover located in cover position 40 all around under mechanical tension on the inner walls 50 and 60 is applied. The cross section of the closure 10 is thus greater in the relaxed state thereof than the cross section of the housing G.

When in cover position located cover 40 this is against a movement transverse to the longitudinal direction L by positive engagement and against movement in the longitudinal direction L by frictional engagement on the base body 30 held.

In the closed position is also the closure 10 against a movement transversely to the longitudinal direction L by positive engagement and against a movement in the longitudinal direction L by frictional engagement on the base body 30 held. To ensure this, the basic body points 30 on its inside projections V on, with the closure 10 has at least recesses into which the projection V in befindlichem in the closed position closure 10 eingreiften.

Further, the shutter is 10 in the closed position with cover located in the cover position 40 against movement transverse to the longitudinal direction L by positive engagement and against movement in the longitudinal direction L by frictional, force or material connection to the cover 40 held.

The closure 10 is with the cover removed 40 through the open side surface F transverse to the longitudinal direction L, that is laterally, in the body 30 insertable and in this case in the closed position with the main body 30 latched. Likewise, the closure 10 through the open end S1 in the longitudinal direction L in the body 30 and inserted there in the closed position. Ie. the closure can advantageously be either by the open end side S1 in the longitudinal direction L or with removed cover transverse to the longitudinal direction L through the open side surface F in the body 30 be pushed into the closed position.

The closure 10 , the basic body 30 and the cover 40 are each profiles produced by pultrusion, extrusion or extrusion. The cross section of the closure 10 , the cross section of the main body 30 and the cross section of the cover 40 are therefore constant in the longitudinal direction L, respectively. The closure 10 is inside the main body 30 displaceable in the longitudinal direction according to the ART of a runner between a plurality of closed positions.

The closure 10 is preferably made of rubber or a highly elastic plastic. Side extension in the longitudinal direction is preferably at least 1 cm, to tilt the closure 10 in the main body 30 to complicate or exclude the longitudinal direction L.

Of course, the other end face S2 completely covered or closed by a further closure (in 1 not shown).

The closure 10 is with its contour 20 the profile 30 and the cover 40 imitated in such a way that these the inner contours 50 and 60 the profiles to be closed 30 and 40 with an oversize follows, that of the choice of the material of the closure 10 depends. The closure can preferably both from the side (ie by the open Seitenflächre F) and from the front (ie frontally) in the profile 30 be used. After mounting the profile cover 40 can the shutter 10 only from the front (front side) insert.

Due to the elasticity of the material of the closure 10 Its contour snugly adapts to seal the profiles 30 . 40 against frontal penetration of dust and water. The thickness of the material of the closure gives this the stability in the main body, in order to withstand z. B. by shock and swing to ensure the tightness.

The selection of the material of the closure may be subject to z. B. of its elasticity, closed porosity, heat resistance, compressibility and / or environmental compatibility. About the elasticity of the material of the closure and the Maßzugabe the contour, the tightness is determined. The above properties allow with the cover removed 40 a quick assembly of the closure through the open side surface F.

Industrial Applicability:

The Invention is industrially applicable for. B. in the field of light barrier technology, Sensor technology, lighting technology, photometry, the Process automation, robotics and factory automation.
