DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a vibration-damping support for a dental separator, which has at least one inlet, at least one outlet, and a centrifuge, wherein the support is provided with line connections, and each inlet and outlet of the separator inserted into the support communicates with a line connection of the support.
2. Description of the Related Art
A support of this kind can be found for instance in International Patent Disclosure WO 89/04641. The separator shown there comprises two partial units; one part, which separates suction air from the mixture and decants solids in the collection container, can be pulled out in drawerlike fashion from the support. The second part includes a centrifuge, whose inlet and outlet communicates via elastic pieces of tubing with the line connections of the support, and which rests on a bearing plate. After the removal of the elastic pieces of tubing the centrifuge can be removed at the top. This is relatively complicated, and it is the object of the present invention to embody a support of the type referred to at the outset in such a way that the separator is easier to remove.
SUMMARY OF THE INVENTION
According to the invention, this is attained in that the support has two parts, wherein the first part can be mounted in stationary fashion and can be disposed removably on the second part of the separator, and that the two parts are jointed together by means of vibration-damping intermediate components. Since the vibration-damping intermediate components are thus components of the support, the separator can be removed from the second part of the support, to which it is fixed by arbitrary connecting means.
The two parts of the support are manufactured in particular from a first plastic, for instance a polyamide or a polypropylene, and preferably embodied essentially in the shape of a U. The vibration-damping intermediate components are in particular of a polyamide- or polypropylene-based thermoplastic elastomer, which can be processed in injection molding systems together with the first plastic to make a one-piece product.
Preferred embodiments contemplate that at least one vibration-damping intermediate component is embodied as an elastic tube section or as a movably disposed rigid tube section between an aperture, associated with an inlet or outlet of the separator, in the second part and a line connection in the first part of the support, so there is no need to open any tubing couplings, either.
The support and the separator in this embodiment form an extremely compact unit that requires the least amount of space, and a further preferred embodiment contemplates that the side ridges of the U-shaped inner part form a lateral guide for a separator that can be pulled out in drawerlike fashion.
If retaining tabs which can be engaged from behind for a tightening lever closure are formed on the free ends of the U-shaped inner part of the support, and/or if the side ridges of the U-shaped inner part have tight-fit faces that converge in the direction of removal of the separator and that can be engaged around the outside by corresponding elements of the separator housing, the result after the insertion of the separator is then a tight communication between each inlet or outlet and the line connection of the support. Optionally, the mouth of the tube section can be equipped with an O-ring. Alternatively, it is contemplated that a sealing ring of the elastomer of the pipe section is coextruded on the inner portion of the support in the region of the mouth of the tube section.
The options for mounting the separator are greater if at least one elastic tube section is disposed in a corner region of the support and communicates with two line connections pointing in different directions. An unneeded line connection is closed off by a stopper.
The side ridges of the approximately U-shaped outer part, mounted in stationary fashion, can also extend obliquely at an angle of 45.degree.. Connection components with a 45.degree. angle
