Definitions

  • the invention relates to a dental device, which contains a horizontal guide provided with lateral slots, which has a longitudinally movably mounted slide on which a support part protruding from the slot is arranged for a further device.
  • the object of the present invention is to provide an improvement, that is to say, to provide measures with which the above-mentioned components can be avoided with simple constructional means.
  • a band guided at the slot ends is arranged on the slide or on the support part, which covers the slot section which forms when the slide moves from one position to the other on both sides of the support part.
  • the tape can be unwound or wound from winding drums arranged on the slot ends when the slide is adjusted, or can be guided as an “endless tape” over deflection rollers arranged on the slot ends.
  • the patient chair 1 shows a diagrammatic representation of a dental work station, consisting of a patient chair 1, a doctor's device 2 arranged to the right of the patient and a helper device 3 arranged to the left of the patient chair.
  • the patient chair 1 essentially consists of an upper part of the chair and a lower part of the chair .
  • the lower part of the chair contains a base part 4, in which a horizontal guide 5 for the doctor's device 2, which will be explained in more detail later, and electrical and / or pneumatic supply modules combined in a junction box 6 are arranged, as well as a height adjustment device for the seat and Backrest of existing chair upper part 8.
  • the device 3 is also adjustably supported parallel to the longitudinal axis of the chair by means of a horizontal guide 9 (FIG.
  • the fixed base part 4 over the entire length of the chair, 1 extends approximately from the rear edge of the seat to at least the foot end of the seat or to the right end of the connection box 6 in the illustration according to FIG. 1, the horizontal guide 9 for the assistant device 3 on the height-adjustable chair upper beam 10 only extends over its length.
  • FIG. 3 shows the structure of the lower part of the chair including upper part 10 of the chair in an exploded view. The view is from the side from which FIG. 2 is to be viewed.
  • the base part 4 is essentially formed from a base plate 11 which is rectangular in plan and which accommodates all the supporting parts, in particular the height adjustment device designated by 60 and the support 10 for the chair upper part 8, and a frame surrounding the base plate 11, which in turn consists of two the shorter sides arranged end pieces 12 and formed on the longer sides trim parts 13 and profile elements 14 is formed.
  • the end pieces 12 are designed as corner profiles, i.e. they have end parts 12a which are angled at right angles and encompass the shorter sides of the base plate 11 and into which elastic connecting elements 15 are inserted, to which the trim parts 13 or the profile elements 14 can be attached.
  • the right end piece 12 shown in the figure contains a shoulder 16, on which the lower end of the bellows 7 is hung.
  • the end pieces 12 are screwed onto the base plate 11, for which purpose tabs 18 'are arranged on this fastening block 17 and on the end pieces 12.
  • the full-surface covering parts 13 are cross-divided into a section 13a, which corresponds essentially to the length of the chair upper part carrier 10 or the bellows 7 surrounding the height adjustment device, and a section 13b, which corresponds to the remaining length, essentially the length of the connection box 6, corresponds.
  • a holding part 20 is arranged on the base plate 11 or on a strip 19 connected to it, adapted to the profile of the covering parts 13, onto which the covering parts 13a, 13b are pushed with their one ends for fixing before they are attached to theirs other ends are connected to the end pieces 12 by means of the elastic connecting elements 15.
  • the trim part 13a like the right end piece 12, also contains a shoulder 16, on which the bellows 7 is hooked.
  • the transverse division is also present in the angle profiles 14; here, too, the individual parts are connected to one another by elastic connecting elements 15; the upper angle section 14a, like the covering part 13a, contains a corresponding extension 16 in order to be able to fasten the bellows 7.
  • a major advantage of the transverse division of the trim parts and angle profiles in the manner described can be seen in the fact that the same trim parts can be used for the trim of both the seat support and the base part, specifically for a chair construction with a short base part, e.g. without connection box, as well as with a long base part, e.g. with junction box.
  • the two angle profiles 14 form a slot 21 over their entire length, from which a connection or support part 22 projects, on which the support column 23 (FIG. 1), which is bent at the bottom, can be fastened for the device 2.
  • the support part 22 is fixedly connected to a slide 24 which is guided within the base part 4 over the entire length of the slot 21 in the horizontal guide 5.
  • the slot 21 is covered in each position of the carriage 24 by a belt 25 hung on the carriage 24, which is guided as an endless belt over deflection rollers 26 approximately rectangular.
  • various supply lines 27 which are joined to form a flat band and which bring the media (air and / or water and / or electrical current) required in the device 2 from a central supply source in the connection box 6 to the support part 22.
  • the chair upper part support 10 also consists of a base plate 31 which is rectangular in plan and has the same width as the base plate 11 and a frame consisting, on the one hand, of end pieces 32 on both sides and, on the other hand, trim parts 33 and angle profiles 34, which in turn are attached by means of corresponding elastic connecting elements 35 are attached to the end pieces.
  • a base plate 31 which is rectangular in plan and has the same width as the base plate 11
  • a frame consisting, on the one hand, of end pieces 32 on both sides and, on the other hand, trim parts 33 and angle profiles 34, which in turn are attached by means of corresponding elastic connecting elements 35 are attached to the end pieces.
  • trim parts 33 and angle profiles 34 which in turn are attached by means of corresponding elastic connecting elements 35 are attached to the end pieces.
  • approaches 36 On the end pieces and on the angle profiles are approaches 36, on which the bellows 7 can be hung.
  • the end pieces 32 are identical to the end pieces 12, that is to say they have fastening tabs 38 in the same place and at the same height; the associated brackets 37 are provided in the base plate 31.
  • the trim parts 33 also have the same dimensions as the trim sections 13a, which among other things simplifies the storage of the parts and also makes it possible to exchange the parts with one another.
  • the right end piece 12 provided with a shoulder can be used from the base part 4 to cover the upper part carrier.
  • connection or support part 42 protrudes through the slot 41 formed by the two angle profiles 34, a connection or support part 42, to which the support column 43 (FIG. 2) of the device 3 is attached either directly or via a support arm.
  • the slot is covered by a webbing 45.
  • the horizontal guide 5 contains a continuous shaft 47, which is held in bearing blocks 46 and on which the slide 24 is mounted so as to be longitudinally displaceable.
  • the carriage 24 is supported by a roller 48 on a U-profile 49.
  • the four deflection rollers 26 guide the belt 25 at the slot ends, in such a way that it runs approximately rectangular.
  • the band 25 forms a loop between two further deflection rollers 50.
  • a friction wheel 51 which is coupled to a drive unit 53 via a magnetic coupling 52, presses on the belt 25.
  • the horizontal guide 9 for the device 3 is constructed in principle the same; however, it contains no drive.
  • the webbing ends 56 can be detachably attached to the carriage by means of screws or can also be attached to a corresponding hook on the carriage using a bracket. If the device adapted to the support column 23 is not to be adjusted by motor, but by hand, or even if the webbing cannot be guided in a square for reasons of space, the endless guidance of the belt can be dispensed with and the slot cover, for example, by at the angled end parts of the End pieces (instead of the front deflection rollers 26 in Fig. 3) arranged take-up rollers for the then two-part webbing are provided.
  • FIG. 5 and 6 show details from FIG. 3 and show the structure of the base part. 6 shows in particular the design of the two profile strips, which form the slot for carrying out the slide or the supporting part connected to it.
  • the profile strips are angle profiles that with their flat surfaces to the outside and with their leg ends Belt strap are arranged facing. Parts 14a of the profiled strips 14 slightly angled inward toward the band cover the belt a little in the assembled state and lie against it slightly, so that a largely dust-free slot cover is provided.
  • All cladding profiles, i.e. both the full-surface cladding parts 13 and the profile strips 14, have the same profile at the connection points, that is, where the connecting elements 15 engage, which simplifies the construction, keeps the storage costs low and also gives an exchange of the parts with one another .
  • the end pieces with molded bellows holder can be used for both the base part and the seat support;
  • the full-surface and slit-forming cladding profiles can alternatively be provided on the left or right side of the chair or on both sides of the chair, depending on whether, and if, on which side of the chair a device is to be slidably mounted.
