DETAILED DESCRIPTION OF THE INVENTION

[0029] The transportable autonomous dental unit, object of the present invention, comprises an operating structure that is adequate for dental procedures transported by a container, as shown is FIG. 1.

[0030] In order to transport the dental unit, there is a prismatic container (10) that has a base (11) with girders (111) to support and to be moved by specific equipment.

[0031] The container (10) has two side faces arranged in opposition (12a) that can be fitted to the base (11) and two other side faces (12b) that have an articulated flap (121) fixed to the girder (111) of the base (11), said flap (121) is provided with a through hole that engages in a pin arranged on the surface of said side face (12b) with clamp locking (122), as detailed in FIG. 2B, creating fast couplings.

[0032] For the mobility of the container, casters are arranged (20) fixed to the base (11) of the container (10) by a support (201) that is fixed to a shaft (112) that extends between the sides of the base (11), said support (21) arranged in the gap of the girders (111) and having a shaft (211) to fix the caster (20) and in the opposite end, an indentation (212) of diameter equivalent to the shaft (112).

[0033] On the end of the shaft (112) a spring (113) is installed, which, once the shaft is rotated (112) by a tool inserted in the recess (12a), it is extended, moving the support (21) until the indentation (212) engages the shaft (112). This way, the caster (20) is positioned away from the base (11), allowing the movement of the container (10). In situations in which the use of casters (20) is not necessary, by means of a movement contrary to the shaft (112), the indentation (212) is uncoupled from the coupling in said shaft (112) and the spring (113) returns the caster (20) to the initial position, juxtaposed to the base (11).

[0034] The container (10) has handles on its external surface (13).

[0035] As detailed in FIG. 4A, on the base (11) of the container (10) there is a drawer (14) installed that moves on linear guides fixed to the lower face of said base (11). The drawer (14) stores the necessary tools to assemble the unit.

[0036] On the base (11) of the container (10) there is a terminal (15) that has connections for the water inlet duct (151), for the wastewater duct (152), and for connecting a power source (153), allowing the coupling of the dental unit to the electrical, water, and sewage infrastructure of the installation site.

[0037] As presented in FIG. 3A, on the base (11) of the container (10) there are cradles (14) to support the reflector during the containment and transport of the disassembled operating structure.

[0038] On the base (11) an inclined column (30) is arranged, fixed by screws, said column (30) that supports the structure of the dental chair. As detailed in FIG. 3B, the inclined column (30) works as a compressed air tank, having a manometer (301), drain (302), and safety valve (not shown). At the compressed air outlet (303) for supplying the peripherals, a steam drain with a manometer (304), an automatic drain (305) and valve (306) is installed, which allows adjusting the air flow and interrupting it, by manual adjustment.

[0039] A compressor (307) is installed on the base (11) to supply the needs for compressed air of the pneumatic peripherals and suction device. To control the pressure in the tank (30), there is a pressure switch (308).

[0040] In the extreme upper portion of the column (30) a plate (31) is arranged, where the structure of the dental chair is fixed by screws, which includes the seat support (S1), the backrest support (S2), the leg rest (S3) and headrest (S4).

[0041] The structure of the dental chair includes a first rectangular frame (50) fixed by a plate (31), said first rectangular frame (50) has on its frontal face, a pair of flaps (51).

[0042] On this pair of flaps (51), a second rectangular frame (70) is fixed, which supports the leg rest (S3) of the dental chair. The second rectangular frame (70) has flaps (71) coinciding with the flaps (51), said flaps (51) and (71) juxtaposed and held together by an articulation pin (72).

[0043] To adjust the inclination of the second rectangular frame (70), a support with a lever (52) is provided, installed at the first rectangular frame (50). A rod (521) is fixed to the support (52) by a pin (522) tensioned by a spring (523) and the opposite extremity of said rod (52) is fixed to a flap (73) of the second rectangular frame (70) through a pin, as shown on FIG. 3E. As the lever (52) is moved, the extremity of the rod (521) positioned on the support (52) is moved upwards, with locking happening due to mechanical interference between the rod (521) and the support (52) when said support (52) is tensioned by the spring (523)

[0044] On the rear edge of the first rectangular frame (50) a U shaped support (60) with side flaps (61) is fixed by screws, the side flaps (61) being facing upwards and aligned with the side of the rectangular frame (50). In the extreme free portion of the side flaps (61) there is a through hole (611) where an articulation shaft (62) is installed fixed by an elastic ring (631) followed by flanges (63) that associate a backrest support (80), shown on FIG. 3A, and a support for side arms (81) fixed on the flange (63), shown in FIG. 4B.

[0045] To move the backrest (S2), a movement mechanism is provided comprising a pair of rods (40) connected by a shaft (41) where a spindle (42) driven by a reducer motor (43) is coupled, as detailed on FIG. 3C. At the opposite end to the arrangement of the shaft (41) a fixation means (42) is arranged to the lower edge of the backrest (S2). The backrest (S2) inclination adjustment is done by the spindle (42) in which end-of-course switches are provided, where the rods (40) transfer mechanical movement from the spindle (42) to the backrest (S2) support.

[0046] The backrest (S2) is fixed to the support (80) by screws, said backrest (S2) has a telescopic rod (82) on its upper edge, which is responsible for headrest (S4) height adjustment, and at the junction of the shaft at the end of the rod (82) a multi-articulated mechanism (821) is provided for adjustment of the headrest.

[0047] The instrument table (90) has an arm (91) fixed to the first rectangular frame (50) through coupling to a shaft (53), allowing said arm (91) to move in the surroundings of the dentist chair, as shown in FIG. 5A.

[0048] On the side of the first rectangular frame (50) a support structure (100) is arranged supported by a supporting member (not shown). The supporting structure (100) has a pair of fittings (100a) and (100b) where the articulated arm (921) of the reflector (92) and the movable arm (941) of the spittoon (94) are fitted respectively.

[0049] Disposal of water from the spittoon (94) is done in a first tank (R1) coupled immediately below said spittoon (94) and water is supplied to the spittoon (94) by a water inlet duct (151) connected to the hydraulic network.

[0050] The equipment features a UV light emitting diode (LED UV-C/280 nm) installed at the second tank (R2) where water is stored to be dispensed into the triple syringe, ultrasound and other handparts. The LED reduces the concentration of microorganisms, dismissing the use of chemical products. As it is connected to the equipment, the UV LED turns on for a previously determined period, turning on again in cycles, in order to guarantee the disinfection of the water in the tank (R2).

[0051] Fluid that comes out of the tank (R2) is heated and goes through a heating unit where water is heated to a temperature between 37? C. and 47? C. by a source of light powered by a transformer, in order to supply the syringe and the ultrasound with heated water.

[0052] As shown in FIG. 6, the table (90) is composed by a triple syringe, a terminal for coupling a high speed turbine, a terminal for coupling a pneumatic micromotor, a piezoelectric ultrasound, a venturi suction device, a LED curing light, a stainless steel tray to accommodate instruments.

[0053] As shown in FIG. 7, a dental stool with a seat (110) fixed by a piston (101) associated to a base with casters (102), whose assembly is facilitated by the coupling of the seat (110) through a handle (not shown) in the piston (101). Disassembly of the dental stool allows its inclusion in the container (10).
