Definitions

  • the present invention relates to a dental treatment chair according to the preamble of claim 1, wherein a seat is height adjustable relative to a base of the treatment chair between a home position and a maximum position.
  • Dental treatment chairs are usually adjustable in several degrees of freedom in order to position the patient ergonomically and treatment-appropriate for the treatment to be performed.
  • a classic dental chair consists of a height-adjustable seat, at the end of a seat back against the seat pivoting backrest is arranged.
  • the backrest is usually followed by a head pad for supporting the patient's head.
  • the adjustment of the position of the backrest and the head cushion is usually possible regardless of the height adjustment of the seat.
  • treatment chairs are known in which the seat not only height adjustable, but also also slightly pivotable to allow a so-called Trendelenburg movement.
  • the present invention is particularly concerned with the height adjustability of the bench of the treatment chair.
  • various drive and transmission mechanisms are known which allow adjustment between a low home position and a maximum position.
  • the drive and the lifting mechanism can be arranged for example below the seat, but there are also dental treatment stations are known in which the central supply device is formed by a rectangular column, the patient chair then arranged laterally of the column and with a located in the column Drive is coupled.
  • the height adjustment of the treatment chair should move in a range that allows optimal or pleasant treatment for the treating dentist. Since dentists have different sizes, this means that the height adjustment should also be within certain limits, which are dependent on the size of the doctor. Furthermore, the range of motion should be dependent on whether the dentist prefers treatments performed standing or sitting. Finally, the arrangement of the Treatment chair opposite the columnar base also on whether the dentist is a left or right handed person.
  • a dental treatment chair with a columnar base and a laterally arranged height adjustable seat known.
  • the seat is coupled to the drive via a transmission mechanism having a vertically movable support arm. The points of attack of the carrier arm on the drive and on the seat are of different heights.
  • the present invention is therefore based on the object to provide a novel and particularly cost-effective way to tailor the height adjustment and arrangement of a dental treatment chair in a simple manner to the needs of a dentist.
  • the solution according to the invention is based on the idea of designing the coupling between the seat of the treatment chair and drive with a vertically movable support arm, at the end facing away from the drive, the seat is fixed, wherein the support arm is formed inclined so that the points of application of the support arm to the drive and the seat are different in the vertical direction.
  • This solution makes it possible to adjust the height adjustment and arrangement of the seat in a simple manner to the needs of a dentist by using differently shaped, preferably Z-like support arms.
  • the use of two different support arms is sufficient, which can optionally be used, wherein in one of the two support arms of the attack on the drive above the point of attack on the bench and the other support arm of the attack on the drive below the point of attack on the Bench is located.
  • the patient chair can then be coupled with the corresponding support arm to the drive.
  • the seat could be converted in a simple manner from a classic right-handed operation to a left-handed operation.
  • both support arms can optionally be used to adjust the scope of height adjustment to the preferred operation of the dentist.
  • a dental treatment chair which has a columnar base, a seat arranged laterally from the base and height-adjustable relative thereto between a home position and a maximum position, a drive arranged in the base for height adjustment of the seat, and a seat coupled to the drive Transmission mechanism comprising a vertically movable support arm, at the end facing away from the drive, the seat is fixed, according to the invention, the support arm is formed inclined so that the points of application of the support arm on the drive and the seat are different in the vertical direction.
  • the or the support arms are preferably tubular, wherein in the event that two different support arms are selectively provided, they may also have different horizontal lengths.
  • the arrangement of the seat can be adapted in a special way to the preferred mode of operation of the physician.
  • a spindle drive arranged in the base is preferably provided, which has a vertically oriented drive spindle, which is suitably coupled to the carrier.
  • a pneumatic or hydraulic drive would be conceivable.
  • This treatment chair according to the invention generally provided with the reference numeral 10 is part of a dental workstation 1.
  • This workstation 1 has as a central element 2 a columnar supply device which serves to hold, control and supply the corresponding components of the treatment station 1.
  • This service table 4 is primarily used by the treating dentist and is used for storage or control of dental treatment instruments such as drills, scaler and the like.
  • a control of the corresponding components of the treatment station 1 can be carried out. For example, these input elements can be used to adjust the treatment chair 10.
  • a helper inner element 6 is attached to the base 2 via a second pivot arm 5.
  • This preferably used by an assistant element 6 also serves to store and control individual instruments such as suckers or so-called spray handpieces.
  • the control of the patient part 7, which includes a spittoon as well as a water supply, can be made via this helper inner element 6.
  • the equivalent in FIG. 1 illustrated dental treatment center 1 classic dental treatment stations.
  • the central column 2 additionally serves to hold the treatment chair 10, which initially has a seat 11. At the rear end of the seat 11 are also a relative to this pivotable backrest 12 and then a headrest 13 is arranged thereafter. Both components - backrest 12 and headrest 13 - can be adjusted independently of one another in the desired manner, in order to adapt them to the patient, in particular its size, as well as the operation of the dentist. However, the adjustment of the backrest 12 and the headrest 13 are not the subject of the present invention and accordingly shall not be explained in detail below.
  • the present invention relates instead to the height adjustability of the treatment chair 10.
  • a first special feature is that the drive required for this purpose is not arranged below the seat 11, as was previously the case, but instead in the supply unit 2 serving as a base. Thus, under the seat 11 there remains a free space which can be used to attach a footboard 14.
  • the arranged within the base 2 and in FIG. 1 Drive not shown serves accordingly to allow a vertical movement of the seat 11.
  • the seat 11 and thus the patient chair 10 should be able to be adjusted in a range that allows optimized operation for the dentist. It should be noted that both a treatment while standing and sitting is conceivable, with different preferences may exist on the part of the dentist.
  • the area in which the patient chair 10 can be adjusted in height, should therefore be adapted to the needs or wishes of the dentist.
  • an arrangement of the treatment chair 10 on the opposite side of the base 2 should be made possible to allow use by left-handers.
  • the solution according to the invention is based on using a special transmission mechanism for power transmission for the height adjustment of the treatment chair, which, due to its design, enables a simple adaptation of the adjustment range to the individual wishes of the dentist.
  • the FIGS. 2 and 3 show the details of the coupling of the treatment chair according to the invention to the drive located within the columnar base.
  • the drive 20 is designed in the illustrated embodiment as a spindle drive 20 and has for this purpose a motor 21 which is coupled to a vertically oriented drive spindle 22.
  • a guide member 24 is further coupled, which is mounted vertically displaceably on a guide column 23 arranged within the base.
  • the guide member 24 cooperates with corresponding, formed on the side walls of the guide column 23 guide rails 25 together.
  • the treads are formed in this case by steel bands.
  • a pneumatic or hydraulic drive could be used.
  • the coupling of the treatment chair 10 to the drive is now via a support arm 30 which is connected at one end to the guide member 24 and at its other end to the patient chair 10 and the seat 11, respectively.
  • the design of this support arm 30 can closer to FIGS. 4a and 4b be removed.
  • the support arm 30 is formed Z-like or inclined angled.
  • it first has a first end 31 in the form of a fastening flange, which is provided for attachment to the guide part 24.
  • a second end 32 in turn serves the attachment to the seat or a support member located below the seat.
  • Both ends 31, 32 are in this case connected via a connecting portion 33, which is designed in particular such that in the horizontal arrangement of the support arm 30 a total of the second, provided for attachment to the patient chair 10 end 32 is below the first end 31.
  • the point of application of the support arm 30 on the drive is above the point of attack on the bench 11 of the treatment chair, as the representations in the FIGS. 2 and 3 can be removed.
  • a second support arm for attaching the treatment chair 10 could be used on the drive 20, which in the FIGS. 5a and 5b is shown and provided with the reference numeral 40.
  • this alternative support arm 40 has a first end 41 for attachment to the guide member 24 and a second end 42 for attachment to the patient chair 10, both ends 41, 42 are in turn connected via an interconnecting part 43 angled together.
  • the second carrier arm 40 is tubular and formed, for example, by a casting.
  • FIGS. 6 and 7 are removed, which respectively show the arrangement of the two support arms 30, 40 on the drive 20, wherein the Guide member 24 is located in each case in the lowest possible position on the guide column 23.
  • the second end 32 or 42 of the support arm 30 or 40 which serves to hold the treatment chair 10, is arranged lower at the first support arm 30 than at the second support arm 40.
  • the first support arm 30 of the patient chair 10 is adjustable between a particularly low and a predetermined maximum position, with the help of the second support arm 40 of the patient chair from a slightly higher starting position, the FIG. 7 is shown to be adjusted to a maximum height.
  • the first support arm 30 is preferably used in those cases where the dentist prefers a sitting treatment.
  • the support arm 40 in turn serves in particular for the realization of an adjustment, which is advantageous for a preferred dentist.
  • the adjustment can be adjusted by the choice of the appropriate support arm in a simple manner to the needs of a dentist.
  • a further advantage of the solution according to the invention is also that the patient chair can be configured in a simple manner so that it is suitable for use in left-handed operation.
  • essentially only a reversed arrangement of the support arm or of the guide part 24 on the guide column 23 is required.
  • the two in the FIGS. 4a to 5b carrier arms shown different adjustment heights or adjustment ranges for the patient chair 10 can be realized. Since in this case a twisted fastening of the support arms is required, this means that now the use of the first support arm 30 for realizing an adjustment for larger heights is required, while the second support arm 40 allows lower adjustment heights and thus in particular for use in a sitting position suitable is.
  • FIGS. 8 to 10 an alternative embodiment for the storage and management of the support arms shown.
  • a spindle drive with a motor 21 and a drive spindle 22 is used.
  • the guide of the support arm 30 along the column 23 now takes place via a so-called ball recirculation guide.
  • a guide rail 50 is provided on the side facing the support arm 30 side of the column 23, on which a carriage 51 is movably mounted, wherein the carriage 51 is further coupled to the drive spindle 22 and connected to the support arm 30.
  • a friction-free guidance of the carriage 51 in the vertical direction is achieved in that within the carriage 51 balls are mounted, which can roll along running surfaces, which are formed on side surfaces of the guide rail 50.
  • the adjustment possibilities for the treatment chair can be adapted in a simple manner to the corresponding wishes of the user.
