"Operating light"

The innovation concerns an operational employee with at least

a light source arranged in a light housing and ϊ a filter disk arranged in its beam path, which

releasably attached to the luminaire housing by a lock r

is. \

When replacing FiltersGheiben, known surgical lights to different locks. For example, in one of the known operating room lights, a pin [ which is held in this position by means of spring force, \

into a recess and holds in this way the I filter disc. By turning the pen using a k

Wrench, for example a hexagonal wrench, the pin can be brought out of its locking position and so that the filter disc can be removed.

The present innovation is based on the task of \ To create an operating light that is easy to replace \

the filter disc without the use of tools to operate J the locking guaranteed.

The object is achieved for a surgical light of the type characterized at the outset according to the invention in that the Locking a bracket with two see opposite Has bores in which a locking bolt axially ^

Is slidably arranged by means of a helical spring

is supported against the holder of the lock that the Locking bolts in the area between the holes with sew on a sliding pin, the axis of which is perpendicular to the Aehse dee Sperrungabolzena runs and that the sliding pin can be pressed against at least one wedge-shaped Cleitsehiene of a sliding part, the sliding part being perpendicular to the axis of the Locking bolt arranged displaceably and with a Operation handle is connected.

Preferred embodiments are the dependent claims and refer to the figures and the description.

The advantages of the newly trained operating staff lie in the simple and reliable replacement of filter discs

The following is the subject of the innovation based on the figures 1 to 3 explained in more detail. It represent

FIG. 3 shows the actual locking device, a perspective illustration being selected in FIG. 3a while Figure 3b shows a cross section

According to FIG. 1, the light sources 1 are in a concentric arrangement in a cylinder-symmetrical Eehittse 2. The filter disks 4 are located in the radiation direction of the reflectors 3, which with the aid of retaining clips 5 are attached to the insert 7 provided with a transparent protective disk 6. Insert part 7 is with the help a support slopes 8 held by the version 9, which a

On the side opposite the supporting slopes θ there is a counter bracket 10 in the insert 7, which with an opening 11 is provided. The opening 11 engages The locking bolt 12 of the locking mechanism 13, which is pretensioned by spring pressure 13 contains in its interior a sealing bar perpendicular to the axis d / ss 12 displaceably arranged sliding part 14, the operating handle 15 of which is fixedly connected to it the wall of the housing 2 is led to the outside «

For a better overview, a circular insert 7, a circular socket 9 together with the lock 13 are shown in an exploded view in FIG. 2 * The insert 7 contains the transparent protective disk έ on its lower side. while in the upper area it is provided with three spring-loaded Hsltebügeln 5 for the purpose of holding the filter disc 4. In the insert 7, the support slopes 8 and the counter bracket 10 with their opening 11 are diametrically opposite. In addition, the counter bracket 10 is provided with a beveled sliding surface 16 which is used to push back the locking bolt 12 when the insert part 7 is received. The insert part 7 is provided on its lower rim with an amorphous elastic ring 1? Versehet "which seals the gap between the socket 9 and insert 7" The socket 9 provided with the brackets 18 and 19 has a recess 20 to accommodate the support 8 of the insert 7. Opposite this recess 20 is the lock 13 with the one in the opening Ii of the counter bracket IO insertable locking bolt 12 is arranged. The bolt is in the direction of that formed by the circular socket 7

Axis 27 displaceably arranged for better clarification is a detail from Figure 2 based on the figure below 3a explained in more detail.

FIG. 3a shows a fragmentary section from the ring-shaped frame of the insert 7, the counter bracket 10 with opening 11 and sliding surface 16; above this partial arrangement, the socket 9 is also shown in fragments, to which the lock 13 is screwed by the visual screws 21, 22. The lock 13 consists essentially of a holder which is U-shaped and in the outer areas of its legs 23, 24 is provided with two opposite bores, in which the locking pin 12 is guided. Due to the perspective illustration, only the bore 26 in the leg 24 can be seen. The locking bolt 12 is arranged displaceably in the direction of the axis formed by the circular socket 9. The sliding part 14, which is also U-shaped, is arranged inside the upwardly open U-shaped holder of the lock 13. The two legs 28, 29 of the U-shaped sliding part 14 are provided with two opposing openings 30, 31 for the passage of the locking bolt 12, these openings are in the form of elongated holes 15 through an opening in the middle part of the U-shaped holder of the lock 13 * Above the web-shaped middle section of the sliding element 14, two wedge-shaped sliding rails 32 are arranged, on which a sliding pin 33 arranged with the locking bolt 12 perpendicular to its bolt axis is actuated by the pressure of a helical spring 34 can be pressed. The sliding pin ragl on both sides beyond the cross-section of the bolt. The coil spring 34 is arranged coaxially to the locking bolt 12; it is on one side with the help of a through the elongated hole

13 supported. The spring force acts on the other side against a spring plate 36 pushed onto the locking bolt 12, which applies the force directly to the neighboring Slide pin 33 transfers. In this way it is ensured that when the sliding part 14 is displaced in the direction

of the axis 27 (according to FIG. 2) of the slide pin 33 firmly on |

arranged at a sufficient distance from one another so that they are at ·;

Movement of the sliding part 14 in each case in the tangential direction \

be guided past the locking bolt 12. Since both slide rails 32 have a congruent shape and are arranged parallel to each other, the slide pin 33 retains without any special additional measures, always its orientation in relation to the axis 27. Through the two openings 30, 31 in the form of elongated holes in the sliding part

14 and the implementation for the operating handle 15 in the Holding the lock 13, the sliding part 14 is restricted to one degree of freedom, so that the displacement only can be done in one direction. In the area of its end, the locking bolt 12 has a bevel 37, in order to facilitate the locking of the insert part 7 by lifting it up.

FIG. 3b shows the lock 13 with it in cross section U-shaped holder, the legs 23, 24 of which with the bores 25, 26 for guiding the locking bolt 12 are provided. In the area of its central web is the holder with a bore 38 for Duchführung dos with dom sliding 14 firmly connected bolt-shaped attachment grips a 15 Provide «Furthermore, the Langleehöf are five in cross-section 30, 31 can be seen in the sliding part 14, whereby in connection

with the actuating handle 15 guided through the bore 38, a clear guidance of the sliding part 14 is made possible.

The spring plate 35 has a reduced diameter in the region of the implementation through the elongated hole 30, so that the spring force is transmitted directly to the leg 23 of the bracket. The spring plate 35 can consist of one part consist of two different diameters, but it can also consist of two separate disks of different diameters be composed. Since no spring force acts on the leg 28 of the sliding part 14, this also occurs in this area no friction on. Unlocking is thus possible in a simple manner without any particular expenditure of force. Inside the U-shaped Space of the sliding part 22, the rear wedge-shaped slide rail 32 can be seen, against which by means of spring pressure the Slide pin 33 is pressed.
