Definitions

  • the invention relates to a dental patient chair with at least the upper part of the chair carrying the chair seat, with a height adjustment device for the upper part of the chair containing lower part and with at least one adaptable to the lower part of the chair, which requires various media such as air, water, electrical current, which means Supply lines are led from a junction box arranged on the floor through the lower part of the chair into the device, the supply lines for the media in the area of the adaption are divided and form a plug-in connection with coupling means arranged on a connecting part and with a matching counterpart arranged with the coupling means that can be brought into engagement and thereby establish the media connection.
  • the lines carrying the supply media run through the lower part of the chair to an outlet opening near the device, exit 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 releasably connected to one another by a plug-in device which can be formed by 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 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 connected to the chair, then the media connection must be established using the plug-in device; Then the inner parts of the sliding track are to be covered with 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 undesired 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, should be made easier than before.
  • the connecting part and the matching counterpart are designed for mechanical coupling of the device to the lower part of the chair and for this purpose, in addition to the coupling and counter-coupling means for the media connection, also coupling and counter-coupling means for a mechanical coupling of the Parts included, the coupling and counter-coupling means for the media connection being arranged such that they come into engagement with one another when the device is mechanically coupled to the lower part of the chair.
  • 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 for a first connection part for coupling a doctor's device close to the floor on 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 carrier.
  • the connecting parts are advantageously fastened to a guide carriage which is part of a sliding track which is 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 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;
  • 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 connection 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 horizontal guide 9 for the assistant's device 3 on the height-adjustable chair top support 10 only runs over its length.
  • FIG. 3 shows the structure of the lower chair part including upper chair part support 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 accommodates 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 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 essentially corresponds to the length of the chair upper part carrier 10 or of 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.
  • a holding part 20 is arranged on the base plate 11 or on a bar 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 an extension 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, from which a connection or support part 22 projects, on which the support column 23 (FIG. 1), which is bent off 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 used in the device 2 open into the slide 24 and form a flat band Appropriate media (air and / or water and / or electrical current) from a central supply source in the terminal box 6 to the support member 22.
  • the chair upper part carrier 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 cladding 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 cladding 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 fastened either directly or via a support arm.
  • the slot is covered by a webbing 45.
  • Base parts 61 are formed on the base plate 11 of the base part 4, on which a box-shaped frame 62 which is open at the top and bottom is fastened.
  • a scissor arm construction formed from two parts 63, 64 is articulated on the one hand on the frame 62 and on the other hand on the chair upper part support 10.
  • the scissor arm parts 63, 64 have the same structure except for the pivot point of a drive which will be explained in more detail later, i.e. they each form a long support arm 63a, a shorter support arm 63b and a transverse stiffener 63c in between.
  • the shorter support arm 63b, 64b has approximately half the length of the longer support arm 63a, 64a and is guided in a common axle bearing 65.
  • the ends 66 of the parallel support arms 63a, 63b, which end at the same height, are mounted on the upper chair support 10; the free end 67 of the longer support arm 63a is articulated to a bush 68 which, together with a guide rod 69 attached to the frame 62, forms a horizontal guide.
  • the two scissor arm parts 63 and 64 are arranged relative to one another in such a way that the legs of the U-shaped support arms face one another.
  • the two scissor arm parts can thus be arranged horizontally in the lowest position.
  • the interlocking of the scissor arm parts would make an even lower end position possible if this were necessary due to certain design requirements.
  • the design of the lifting device in the manner described makes it possible to make the entire lifting device extremely narrow, as a result of which more space is created to the side of the scissor arm parts compared to other designs.
  • a further advantage is that sufficient storage space is provided below the scissor arms lying horizontally in the lower position for the accommodation of the supply lines.
  • Base part 4 and upper chair part 10 form on each side of the height adjustment device 60 a space 78 and 79, respectively, which serves as a cable duct for the cables 27 and 28.
  • This space extends parallel to the longitudinal axis of the chair and is on the one hand through the base and frame parts 61, 62 and on the other hand limited by the bellows 7.
  • the supply lines 27, 28 are combined in the manner of a ribbon cable and laid in the cable ducts 78, 79 to form a loop so that they can follow the movement of the devices.
  • One end of the lines ends in the carriage 24 or 44, thus moving along the guideway, the other end opens in the connection box 6.
  • the length of the lines there is dimensioned such that they are still adequately guided in the respective end positions within the cable duct.
  • FIG. 6 shows the guide carriage 24 with the supporting or connecting part 22 fastened there in an enlarged view.
  • At the front of part 22 are two centering and holding pins 80 (only one can be seen in the illustration), which engage in the assembled state in corresponding bores 81 on the corresponding adapter counterpart 82 of the support column 23, on which the device 2 is held. With these two pins, a mechanical coupling of the device and chair is achieved on the one hand, and the other coupling members are centered on the other.
  • the electrical connection is made by means of a multiple connector strip 83 fastened to the connecting part 22, the contact pins (not shown in more detail) of which engage in the coupled state in resilient receiving parts of a corresponding mating coupling piece 84 fastened to the adapter counterpart 82.
  • the pneumatic and / or hydraulic connections are made by means of connecting members 85 which engage in or engage over corresponding counter-members 86.
  • These connection and counter-members 85, 86 are held on the relevant adapter parts 22 and 82 by means of common locking plates 87, 88. 8, which shows a connection in the assembled state in longitudinal section.
  • the locking plates 87, 88 press the connection and counter-members 85, 86 against a corresponding contact surface of the adapter part 22 or 82 against a flange 89 formed by a collar or a locking washer.
  • at least the bore 90 is in one Adapter part 82 is much larger than the diameter of the connecting member 86 itself.
