Definitions

  • the invention relates to a dental patient chair with at least the chair seat.
  • the chair upper part a height adjusting device for the chair upper part containing chair lower part and with at least one adaptable to the chair lower part, which requires various media such as air, water, electrical current which are guided by means of supply lines from a junction box arranged on the floor through the lower part of the chair into the device.
  • the supply media-conducting lines extend through the chair base through to a located in 'near the device outlet opening, emerge from there and open directly into the interior of the device.
  • the supply lines are at one or more points by clamps or the like. fixed and can also be cross-divided in this area, the division ends then being connected to one another by a terminal strip or a multiple plug.
  • the device is adapted via a support designed as a sliding track, which is screwed to the side of the chair top support as a separate component.
  • Various cladding parts finally cover the inner parts of the sliding track.
  • the device In order to connect the device to the patient chair ready for operation, a relatively large amount of assembly work is required. First, the device must be mechanically coupled to the chair, then the individual supply lines must be connected to each other; finally, the inner parts of the sliding track have to be covered by appropriate cladding parts.
  • the lateral adaptation of the sliding track which is designed as a separate component with its own torsion-resistant housing, also forms undesirable protruding parts and parting lines which do not result in a compact construction.
  • the object of the present invention is to provide an improvement, that is to say to create a patient chair of the type mentioned, in which the assembly effort for an operational connection of a device to the chair can be reduced by a compact design.
  • the assembly of a device on site, i.e. at the customer's premises, should be made easier than before.
  • the lower part of the chair contains a connecting part which contains coupling means both for a mechanical coupling and for a coupling of the individual media and that the device to be connected to it has a counterpart matching the connecting part of the lower part of the chair , which with mechanical coupling of the device can be brought into engagement with the coupling means and thereby creates the media connection counter-coupling means.
  • the lower part of the chair can be completed in the factory and equipped, manufactured and checked with the necessary media lines so that the device only needs to be connected to the chair on site, i.e. at the customer's.
  • the connecting part which contains all the electrical, pneumatic and hydraulic connecting elements, can advantageously be used at the same time as a test adapter in order to be able to check the function of the line laying at the factory.
  • a particularly advantageous embodiment provides to provide a first connection part for coupling a doctor's device near the floor to the chair lower part and a second connection part for a patient-related device with flushing and flushing options, often also referred to as a water unit or assistant's device, on the height-adjustable upper part support.
  • the connecting parts are advantageous attached to a guide carriage, which is part of a sliding track integrated in the lower part of the chair.
  • the sliding track for the connection part near the floor can advantageously be arranged over the entire length of the base part of the chair, starting approximately with the rear edge of the seat and ending approximately in the region of the front edge of the footrest; for the sliding path of the connection part remote from the floor, on the other hand, it is sufficient if it is arranged on the side of the chair on the side of the chair opposite the connection part near the floor, only in a length corresponding to the seat depth on the seat support.
  • the base part and / or seat support form a free space along the chair axis, in which the guide slide is held in a longitudinally adjustable manner; to the side of the centrally located height adjustment device and lying within the outer limits of the lower part of the chair, there is a cable duct in which the media lines coming from the connection box are in the form of a cable. Lead the loop to the connecting part connected to the guide carriage.
  • FIG. 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 as viewed from the patient and a helper device 3 arranged to the left of the patient chair .
  • the lower part of the chair contains a base part 4, in which a horizontal guide 5 for the medical 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, concealed by a bellows 7, 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 horizontal guide 9 for the assistant's device 3 on the height-adjustable chair top support 10 only extends over its length.
  • Fig. 3 shows the structure of the lower chair part including upper chair carrier 10 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 has all the load-bearing 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 is formed from two end pieces 12 arranged on the shorter sides and from cladding parts 13 and profile elements 14 arranged on the longer sides.
  • the end pieces 12 are formed as corner profiles, they ie exhibit perpendicular angled, the shorter sides of the base plate 1 1 encompassing end portions 12a that are inserted into the elastic connection elements 15, at which the garnish members 13 and the profile elements can be fixed fourteenth
  • 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 upper chair support 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 terminal box 6 .
  • 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 one Approach 16, on which the bellows 7 is hung.
  • 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 slide 24 by a belt 25 suspended on the slide 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.
