ABSTRACT:
The present invention relates to a device for sealed mounting of a part on a frame, and to the use thereof, in particular for sealed mounting of a window to the bodywork of a motor vehicle.
BACKGROUND OF THE INVENTION
Devices already exist for mounting parts on bodywork or more generally on frames.
Such devices comprise an edging of elastomer material whose body is provided firstly with a link element that is overmolded at least in part on the periphery of the part that is to be mounted, and secondly with an element that provides sealing with the adjacent portions of the frame.
Nevertheless, such devices are not adapted to all mounting situations insofar as the sealing element is of a determined shape and is associated in a non-removable manner to the edging so as to form a one-piece unit.
Under such conditions, it is not possible for the sealing element under all circumstances to ensure sealing contact with the adjacent portions of the frame in an effective and satisfactory manner.
In addition, in the event of the sealing element wearing or becoming damaged, the only solution consists of dismounting the entire part together with its edging and replacing it in full, thereby complicating maintenance operations.
OBJECTS AND SUMMARY OF THE INVENTION
An object of the present invention is to solve those technical problems in a satisfactory manner.
According to the invention, this object is achieved by a device for sealed mounting of a part on a frame, the device being of the type comprising an edging having an elastically deformable body provided firstly with a link element overmolded at least in part on the periphery of said part, and secondly with a sealing element,
wherein said sealing element projects from said edging towards the frame and includes removable fixing means designed to co-operate with complementary retaining means carried by said edging.
In a particular embodiment, said removable fixing means are constituted by a protuberance formed on one of the ends of said sealing element and designed to lock by snap-fastening in a groove formed in the edging.
In a variant, said protuberance constitutes a dovetail of substantially circular section.
In another variant, the opening is narrower than the widest portion of the groove.
According to an advantageous characteristic, said sealing element includes at least one lip and/or tubular section which extends laterally relative to said part to come into contact with the adjacent portions of the frame.
According to another characteristic associated with dynamic sealing, said edging also includes a guide element whose profile matches the outlines of the adjacent portions of the frame.
According to yet another characteristic, associated with static sealing, said edging has both an anchor element for anchoring in the frame, and a positioning and wedging element.
According to yet another characteristic, said sealing element possesses a contact zone for contacting the frame, which zone is provided with a surface covering having sliding properties. This characteristic is advantageous in the context of dynamic sealing when the sealing element and the part move together relative to the frame.
In another embodiment, the peripheral edge of the part is held captive in said link element which forms a clamp.
The invention also provides the use of the abovedefined device for sealed mounting of a window to the bodywork of a motor vehicle.
The device of the invention makes it possible for the edging and thus for the part to be docked relative to the frame in a accurate, stable, and sealed manner whatever the constraints associated with the surrounding shapes, and it also improves the appearance of the assembly.
Mounting of the part is thus simplified and facilitated, and can therefore be automated.
It is also possible to provide for the respective sections of the edging, of the sealing elements, and of the guide, positioning, and wedging or anchoring elements to vary around the outline of a given part so as to ensure that the mounting device is a perfect fit.
The device of the invention applies to any type of mounting, both to mounting where sealing is ensured in dynamic manner (sliding windows), and where it is static (windshields, . . . ).
