Definitions

  • the invention relates to a sealing strip for a slot of a sliding actuator with a fastening strip for fastening to a housing of the sliding actuator, which is provided with a soft, elastic sealing lip for the slot.
  • Sealing strips of the type mentioned (DE-C-40 30 909, DE-U-92 09 185.7) are used to prevent dust or splash water or the like. pass through the slot, and in particular also to prevent light from passing through the slot.
  • a correspondingly soft material is provided which has a hardness of approximately 40 to approximately 50 Shore, in particular a silicone.
  • the fastening strip is molded in one piece onto the sealing lip. Although the fastening strip is thicker than the sealing lip, it does not have a high level of rigidity due to the soft material. It is therefore provided that the fastening strip is provided with recesses or projections with which it is plugged or plugged into corresponding counterparts of the housing of the slide actuator.
  • Fastening means are provided to hold the fastening strip on the housing of the sliding actuator. This results in a complex assembly, since several parts are assembled. During this assembly, the sealing strips can leave their position and then not be correctly positioned afterwards.
  • the invention has for its object to provide a sealing strip of the type mentioned, which allows easy and safe installation.
  • the sealing lip is positively attached to the mounting strip and forms a prefabricated structural unit with it, and that the mounting strip consists of a material different from the material of the sealing lip, the hardness of which is greater than the hardness of the material of the sealing lip.
  • the fastening strip can be attached to the housing of the slide actuator by clipping, hot caulking or screwing on. It is also possible to glue the fastening strip to the housing, since a material can be selected for which there is a suitable adhesive.
  • the prefabricated or pre-assembled unit consisting of a sealing lip and fastening strip is easy and safe to use and can be positioned exactly.
  • the fastening strip consists of a fiber-reinforced plastic.
  • a glass fiber reinforced polyamide can be used.
  • Such a fastening strip has high rigidity, which simplifies its handling.
  • the sealing lip is cast onto the fastening strip.
  • the fastening strip has a web provided with openings, to which the sealing lip is cast in such a way that a skirting board for the sealing lip is provided on one side of the web, the connecting pin penetrating through the openings with a is cast on the opposite side of the web.
  • the fastening strip is designed as a U-shaped frame which surrounds the sealing lip on one long side and on the two ends.
  • a frame has the advantage that it protects the sealing lip during transportation and storage, so that there is no fear of damage to the sealing lip.
  • the legs of the frame are provided with fastening devices.
  • These fastening devices can consist of pluggable and / or clip-on and / or hot-deformable pins or just be through holes for attaching fastening screws.
  • the sealing strip is a prefabricated unit consisting of two parts, namely a fastening strip (10) and a sealing lip (11).
  • the fastening strip (10) has the function of securing the assembly to a housing of a slide actuator and the function of holding the sealing lip (11) in the desired position.
  • the fastening strip (10) is made of a material that has a relatively high rigidity, i.e. a rigidity of at least about 80 shore.
  • a suitable material is, for example, a glass fiber reinforced polyamide.
  • the fastening strip (10) is produced by injection molding.
  • the fastening strip (10) has a slightly trapezoidal base body (12) from which a longitudinal web (13) protrudes.
  • the web (13) is provided with a large number of openings (14) in the area in which it begins on the base body (12).
  • fastening legs (15, 16) which have a greater thickness than the base body (12) and which project perpendicularly and perpendicularly to the web (13) from the base body (12) such that they form a U-shaped frame with the base body (12), which frames a longitudinal side and the two end faces of the sealing lip (11).
  • the two legs (15, 16) are provided with chamfered recesses (17) for receiving fastening means, for example fastening screws.
  • other fastening means can also be provided, for example clip pins or rivetable pins or the like.
  • the sealing lip (11) is cast onto the fastening strip (10), in particular by injection molding.
  • the sealing lip (11) is made of a soft, rubber-elastic material, in particular of silicone. It has a hardness of around 50 shore.
  • An essential component of the sealing lip (11) is an approximately wavy band (18), the design of which can be seen in FIG. 5.
  • the band (18) has a relatively thin wall thickness. The wall thickness is, for example, on the order of 0.2 mm. In each case the successive wave troughs pointing away from the base body (12) in plan view are provided with a closure (19), so that there is a contact surface for a sliding member of a slide.
  • the sealing lip (11) is cast onto the fastening strip (10) in such a way that strips (20, 21) are present on both sides of the web (13), which are connected to one another via the connecting pins (22) penetrating the openings (14).
  • the strip (20) adjoining the strip (18) serves as a baseboard for the strip (18). It runs approximately flush with the surface of the base body (12) pointing in the direction of the band (18).
  • the outer bar (21) is essentially flush with the outer surface of the base body (12).
  • the web (13) ends at a distance in front of the legs (15, 16). This area is also filled with the material of the sealing lip (11), which lies against the inner end faces of the legs (15, 16).
  • a sealing strip is shown, the fastening strip (10) and the sealing lip (11) of which are delimited on both ends by legs (15, 16).
  • an intermediate leg is arranged between the outer legs (15, 16).
  • This leg which then also serves as a fastening element, then divides the sealing lip (11) into two sections.
  • this design looks as if a further fastening strip (10) and a further sealing lip (11) were integrally formed on one of the two legs (15 or 16). It will usually be provided that the two sections also have different lengths.
