Definitions

  • the invention relates to an enclosure comprising a hollow profile with an open side portion on which a covering plate is watertightly attached, the profile being provided with at least one end closure comprising a watertight sealing disposed at the end of the profile.
  • the invention relates to a device comprising such an enclosure as a housing for electronic and/or optical equipment such as a light barrier.
  • IP ingress protection rating
  • a sealing loop of caoutchouc or similar unaccommodating and watertight material is usually disposed around the end section of the profile.
  • the sealing loop is firmly pressed against the end section by a capping member tightly attached to the profile's end.
  • a watertight end closure of the profile is provided by the capping member and the sealing loop embedded therein.
  • a jamming member is provided inside the sealing, the jamming member being adapted to exert a pressing force on at least two opposed side portions of the sealing acting in a transverse direction with respect to a side portion of the sealing which is disposed adjacent to the covering plate and subsequently referred to as plate-adjoining side of the sealing.
  • the present invention originates from the observation that a weak point with respect to the watertightness of the enclosure are the portions of the sealing at which the attachment of the covering plate on the profile is adjoined. It has been found that an arrangement of a jamming member in the above described manner leads to an unexpected strong improvement of the watertightness and constitutes a surprisingly effective remedy with respect to the intrinsic deficiencies of this particular problematic region. In this way, the overall waterproof characteristics of the whole enclosure may be substantially improved. By way of example, an IP value of 65 or better may be obtainable for the profile used as an electronic enclosure.
  • the transverse direction of the pressing force comprises a vector component directed towards the plate-adjoining side of the sealing and a vector component in an orthogonal direction.
  • the jamming member may be provided with a tapering portion at each of the opposed side portions of the sealing. Each of these tapering portions may face the plate-adjoining side of the sealing.
  • an inclined or curved surface on a force transmitting portion of the jamming member may be provided for directing the pressing force in the transverse direction with respect to the plate-adjoining side of the sealing.
  • this tapering portion has a substantially circular curved form.
  • other shapes for a transverse force transmission such as a substantially linear inclination or other curved shapes are conceivable.
  • the tapering portions are disposed in direct proximity to the attachment of the covering plate on the profile.
  • the impact zone of the jamming member may be situated close to the weak point of the sealing.
  • the distance of at least two of the tapering portions to the attachment is less than one fifth, more preferred less than one tenth of the cross section dimension of the profile.
  • the distance of at least two of the tapering portions is smaller as compared to the respective wall thickness of the portion of the profile's end section which is located adjacent to the covering plate.
  • the opposed side portions of the sealing within the scope of this application are defined as any two side portions of the sealing facing the jamming member in an opposed direction component. In general, they are not to be construed with respect to their relative distance to the plate-adjoining side of the sealing. For instance, also a side portion at the upper region that is opposed to a side portion at the lower region of the sealing is conceivable. According to a preferred embodiment, the relative distance of the opposed side portions to the plate-adjoining side of the sealing is essentially equivalent.
  • said jamming member is provided with at least two of said tapering portions at each of said opposed side portions of said sealing for further improving the watertightness at the critical region. More preferred, a step-like arrangement of the at least two tapering portions at each side of the sealing is provided. More preferred, three tapering portions are provided on each side portion of the sealing.
  • the jamming member is provided with at least one upper protrusion comprising at least one of said tapering portions. More preferred, the upper protrusion projects from an upper center portion of the jamming member.
  • said jamming member may provided with at least one lateral projection comprising at least one of said tapering portions.
  • the sealing is provided with corresponding recess structures fitted to the shape of the tapering portions on the jamming member for further improving the pressing force transmission. It is also conceivable, according to another embodiment, that the pressing force is transmitted by means of recess structures formed in the jamming member, in which in this case corresponding projections at the inner circumference of the sealing are engaged.
  • the tapering portions are interconnected via a bridging portion comprising an application surface for applying a force on the jamming member which may then be transferred to the sealing as the pressing force.
  • the application surface may be facing away from the plate-adjoining side of the sealing. In this way, a linear force application on the jamming member directed towards the plate-adjoining side of the sealing can be exploited for exerting the pressing force on the at least two opposed side portions of the sealing and in the transverse direction with respect to the plate-adjoining side of the sealing.
  • said bridging portion may be adapted to exert a pressing force directly on the plate-adjoining side of the sealing.
  • said bridging portion may comprise an impact surface on the opposed side with respect to said application surface for a transmission of this pressing force.
  • this impact surface may be adapted to transmit the force substantially over the total length of the plate-adjoining side of the sealing.
  • substantially the total force is transmitted in the direction of the plate-adjoining side of the sealing.
  • the jamming member is preferably disposed in such a way that it displaces at least slightly towards the plate-adjoining side of the sealing when the force is applied on the application surface.
  • the end closure further comprises a capping member.
  • the capping member is preferably provided with an activation surface for transmitting the force to said application surface on said jamming member. More preferred, the activation surface is provided in such a way that it faces the plate-adjoining side of said sealing.
  • the activation surface may be provided on a protrusion on said capping member. Said protrusion may be arranged inside an inner space of said capping member.
  • an inclination towards the cavity of the profile is provided in between said activation surface and said application surface.
  • This inclination can be used to facilitate a force application on the application surface.
  • the inclination may be provided on the application surface and/or on the activation surface.
  • the application surface of the capping member may be provided with an inclination towards the cavity of the profile.
  • the application surface of the jamming member may be e.g. substantially planar with respect to the length direction of the profile or may also comprise an inclination.
  • the inclination is provided on both surfaces for allowing a smooth and continuous guiding of the surfaces on one another.
  • an activation force may be advantageously applied on the jamming member by advancing the activation surface of the capping member with respect to the application surface of the jamming member along the inclination resulting in a force application towards the plate-adjoining side of the sealing-loop.
  • the inclination has a substantially constant slope.
  • the capping member is provided with exterior walls surrounding the sealing such that the pressing force exerted on the sealing is counteracted by the capping member.
  • the sealing is preferably fitted inside the capping member according to the shape of its exterior circumference. More preferred, at least the portions of the sealing on which the pressing force is exerted are in close contact with the exterior walls of the capping member.
  • the watertight sealing is constituted by a sealing loop. More preferred, the sealing is disposed continuously around the end section of the profile for achieving homogenous sealing properties.
  • a further improvement with respect to the watertightness at the plate-adjoining side of the sealing may be achieved in that the sealing extends into the cavity of the profile, at least on a portion of its plate-adjoining side.
  • the jamming member may also extend into the cavity at this particular region for allowing an advantageous transmission of the pressing force also at the portion of the sealing that is extending into the cavity.
  • a profile may be used with a watertightly attached covering plate extending beyond the end-section of the profile. In this case, a superior water-tightness may be achieved with the sealing and/or jamming member applied at the profile's end section without ranging into the cavity, in particular at the bordering zone with respect to the covering plate.
  • the sealing and the jamming member may be fully or at least partially disposed inside the cavity at the end portion of the profile.
  • the inner side walls of the profile may be used to counteract the pressing force transmitted from the jamming member.
  • At least one plugging protrusion extending into the cavity of the profile is provided on the jamming member. This may allow a correct positioning of the jamming member with respect to the sealing during installation of the end closure.
  • lateral projections of the jamming member are provided with the plugging protrusion.
  • the profile may comprise separate compartment spaces for insertion of the plugging protrusions. The size of the compartment spaces preferably exceeds the size of the plugging protrusions, such that a displacement of the jamming member towards the plate-adjoining side of the sealing is rendered possible during the installation of the end closure.
  • the bridging portion of the jamming member may extend into the cavity of the profile for further facilitating an inner fixation of the jamming member.
  • the jamming member has a substantially frame-shaped structure.
  • the form of the inner circumference of the sealing is preferably fitted to the outer circumference of the jamming member. More preferred, the jamming member may extend around the total inner circumference of the sealing for allowing an optimal positioning of the jamming member. According to another embodiment, the jamming member may only extend over part of the inner circumference of the sealing for still ensuring a good transmission of the pressing force at the two opposed side portions of the sealing.
