DE2552957A1 - Instrument rack for dental table - has slots feeding hoses towards take up roller under table - Google Patents

Abstract

A rack (6) for dental instruments, attached to a swinging table, has the instruments laid out each in its own notch. Behind each notch, and below the surface of the table (10) is a narrow compartment (3) into which that instruments hose is neatly stowed. The hose is stowed automatically by a roller, which runs on the gently sloping floor of the compartment. The loop of hose fits round the roller and is carried down into the compartment by the roller weight. As it reaches the lowest point (hose fully stowed), the roller operates mechanical switchs to turn off the power, etc. The roller then comes to rest in a groove. A second rest groove accepts the roller at the highest level (hose fully extended), and relieves the instrument of the roller weight while the dentist is using it.

Description

Dental device

The invention relates to a dental appliance with a plurality of hose-connected devices Instruments and associated switching means.

Devices of this type are used for the dental treatment of patients with drills, syringes, electrosurgical devices and devices for removing tartar used, means are available that a storage of the instruments in the rest position ensure, as well as ensure that the hose is properly housed.

There are many dental devices with multiple hose-connected instruments known. Some of them only have an instrument tray and leave the hoses Hang freely between the connection end and the instrument, with a twist when in use the hoses cannot be ruled out. Other dental devices with hose-connected Instruments have an instrument tray which is designed as a quiver and Hose reels for winding the hoses with a drive in the sense of winding (e.g. by clockwork spring) as well as means for strain relief of the extended hoses.

Other devices have hose retracts through vertically arranged Rolling guides, in which the hoses in their Rest position in a vertical Able to be drafted and funds for strain relief, the role in a height assigned to the extension length Appropriate means, detachable, hold on tight.

This latter type of hose retraction has the disadvantage that, by the vertical movement paths of the rollers require complex and expensive strain relief means are to be provided and especially when working on the patient lying down, the pull-out of the hose in the horizontal direction requires an additional deflection, which adversely affects the life of the hoses.

The object of the invention is to address the aforementioned disadvantages through a avoid simple, inexpensive construction.

This object is achieved in that each of the operating medium supply hoses is arranged between two vertical walls in the form of a loop and through the weight of a roll inserted in the loop between the vertical Guide walls with their wreaths on the in relation to a horizontal plane in one Angle backward sloping roller conveyors running, tightened and in their rest position is held in an associated location.

The roller conveyor floors should preferably have a gradient of 10 to 45 Degrees to a horizontal plane, with recesses on the roller conveyors at intervals are attached, in which the roles for the purpose of a strain relief of the equipment hoses can lock into place during treatment. When the rollers are in the rest position, shut-off and actuated switching means which interrupt a supply of operating medium. For filing of the instruments in the rest position, support means are provided by their shape the instruments at a distance and in a convenient grip position at an angle to the front and downwards in relation to a horizontal line.

The shut-off means for water and air are mechanically operated Valves running. The invention can of course also in a pivoting and a height-adjustable table.

The invention makes a simple and inexpensive one Accomodation of the hose-connected instruments achieved. The simple construction also leads to a way of working that is less prone to malfunctions.

An exemplary embodiment is shown and described in the drawing: 1 shows a dental framework table according to the invention.

FIG. 2 shows a section through a table in the middle of a roller track.

FIG. 1 shows an equipment table which is suspended from an arm 1 is; The right side 2 of the table is provided with several roller tracks 3 in which the operating medium supply hoses 4 are introduced at one end thereof the instruments 5 are attached. These are stored here in their rest position shown on the instrument tray 6, which by means of the brackets 7 in the front Area 8 of the scaffolding table is attached. Switching means 9 for non-table electrical Controls are provided on the right side wall and a work shelf 1o forms the left side of the table.

2 shows a section through a table housing and in the middle and along a roller conveyor, the lower part 11 of which has the roller conveyor 12 in which the operating medium supply hose 4 is in the form of a loop 13 and through the Roll 14 (in section) is held in an associated position.

The two rings 15 of the roller 14 run on the roller conveyor floor 16 which is laterally limited by about 20-30 mm high vertical turns 17. For strain relief the roller track is provided with recesses 18 at both ends.

The hose connection block 19 is equipped with shut-off means 20, which in the instruments cblage 6 stored instruments by pivoting of the lever 21 are guided into the shut-off position.

The operating fluid hose 4 runs from the connection block 19 to the front end 8 of the table and is by a deflection cam 22 in the roller conveyor 16 guided around the roller 14 after the handpiece 5. Via a support arm, not shown the resources are the mechanically operated valves 20 through the Aufhöngestutzen 23 supplied.
