Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shaft fishing mechanism for a door, particularly a free door, in which the shaft fishing mechanism consists of an upper shaft fishing mechanism part and a shaft fishing mechanism lower part. attached to the opposite upper door edges and arranged such that the pin of the shaft fishing mechanism is movable by the adjustment device within the guide of the upper part of the shaft fishing mechanism. Regarding formal matters.

Such fishing gears usually consist of an upper fishing gear part and a lower fishing gear part, in which case the lower fishing gear part is integrated into the upper door edge opposite the floor door check. The upper part of the shaft fishing mechanism is incorporated into the door frame so as to face the lower part of the shaft fishing mechanism. The pin of such a shaft fishing mechanism is used for door installation and/or
The handle is arranged in the upper part of the shaft fishing mechanism as follows so that it is movable in the axial direction for sushi. That is, whereas for the installation of the door the pin can be completely embedded in the door frame, after the door has been fitted the pin must again be displaced axially downwards.

In this case, it is possible to retract into the lower part of the shaft fishing mechanism which is fitted into the door.

In order to be able to produce this axial movement of the pin, very expensive adjusting devices have hitherto been used (1" Federal Republic of Italy Utility Model No. 1680224). - This adjusting device consists of a two-armed lever, which is supported on a platform in the upper part of the shaft fishing mechanism so as to be pivotable about a horizontal pin. - one of the lever arms cooperates with an adjusting screw, which can itself be threadedly connected in the vertical direction into the upper part of the shaft suspension mechanism, in which case this Lenomeau arm is designed in the form of a fork;
gripping the slide, which is connected to the above-mentioned three-arm by a side pin and is rotatable but immovable on the cylindrical part of the adjusting screw. The other lever arm initially passes through a longitudinal slit in the guide for the bottle and projects with its free front end into the slit in the bottle.

Furthermore, the above-mentioned pin is connected to one of the ζ-arms via a transverse pin. By operating the adjustment screw, the bin can be moved up and down in the axial direction.

This known shafting mechanism and the adjusting device used in this case are not only relatively expensive to manufacture, but also difficult, since the door can only be installed or removed in the partially open position at all times. It also has the major drawback of not being able to do so. This partially open position is disadvantageous. This is because it is on the door check for the floor below.
This is because the door, which is electrically connected via the closing lever, is always forced to close.

This means that the door must constantly be held open against the force of the closing spring when the bin of the shaft fishing mechanism is moved axially during installation or removal.

Furthermore, the known adjusting device requires a relatively large amount of space, since the adjusting screw is arranged far from the guide of the bottle in the upper part of the shaft fishing mechanism.

The object of the present invention is to improve the shaft fishing mechanism of the type mentioned at the outset so that it is not possible to perform all the functions of the shaft fishing mechanism of known structural type, even when the door is closed. It is an object of the present invention to provide a shaft fishing mechanism that allows a door to be installed or removed without being subject to closing forces. Furthermore, it would be desirable in this case to ensure a telescoping and compact design of the adjustment device of the bin, and ultimately to make it possible to manufacture the shaft fishing mechanism more cost-effectively than hitherto. I want to.

This object is achieved in accordance with the invention in that the adjustment device for the bin is assigned to the guide of the upper part of the fishing mechanism. In an advantageous embodiment of the invention, the bottle is axially movable in the guide by a radial movement of a threaded bushing partially surrounding the bottle. The configuration of the shaft fishing mechanism according to the invention has significant advantages over known ones. A compact construction is obtained because the adjustment device of the bottle is assigned to the guide of the upper part of the shaft fishing mechanism. Two-armed arms
It is possible to completely dispense with the use of an adjusting screw which is separate from the guide. This also eliminates the need for special bearings for the forked levers and additional bearing points for the adjustment screw reservoirs.

During regular use of the shaft fishing mechanism according to the invention, it is advantageous that the door can be installed or removed in the closed state. This also eliminates the load of closing forces, and finally also makes it possible to manufacture the shaft fishing mechanism according to the invention more cost-effectively than known construction types. It is rotatable but axially movable and rigidly supported in the receiving chamber of the holder and is engaged by the bottle-shaped protrusion of the wide pin, which has a steeply sloped internal thread groove and the action of the operating tool. It is a good idea to have a separate location.

As mentioned above, by rotating the thread groove bushing which is prevented from shifting in the axial direction, the bottle is moved in the axial direction via the bottle-shaped protrusion and the high pitch internal thread groove. You will be able to do it.

Advantageously, a grooved pin is fitted into said pin, the front free end of said grooved pin engaging in a thread groove of the threaded bushing.

Furthermore, it is advantageous for the operating point of the operating tool reservoir to be arranged in the boxwood of the threaded bushing, which is located outside the receiving space of the housing.

In this case, the barb of the threaded bushing can have a number of working points, which are designed as recesses, for the actuating tool, which is designed as a key spanner.

The notches, which are preferably rectangular in shape and open toward the front, are arranged in a regularly distributed manner on the boxwood of the threaded bushing. The hook of the ax selectively cooperates with one of these notches.

According to a further proposal of the invention, said pin carries with its upper free end projecting from the threaded groove a further grooved pin, which grooved pin is mounted on a shaft at its free end. It engages in a longitudinal slit in the casing of the upper part of the mechanism. Through this second grooved pin, the pin is arranged in a casing in the upper part of the shaft fishing mechanism so that it cannot rotate but is movable in the axial direction.

The collar of said threaded bushing is thinner than the normal gap between the door and door frame, but thicker than the collar that cooperates with the notch in said collar. is advantageous. Thereby, it is possible to reach between the door and the door frame with a key spanner and to rotate the threaded bush even when the door is closed.

In order to prevent unskilled persons from operating the adjustment device, according to another proposal of the invention, the pin adjustment device, in particular the threaded bushing, is provided with a safety device which prevents unskilled persons from adjusting it. I'm forced to. In an advantageous embodiment, the safety device is constructed as a fastening plate 9, which fastening plate has a projection that engages in one of the recesses in the collar of the threaded bushing and thus prevents the threaded bushing from pivoting. 0 In order to eliminate the additional fixing member of the retainer of the fixing plate, it is necessary that the set screw which fixes the upper part of the suspension mechanism to the door frame is used at the same time to hold the fixing plate. It has become.

According to another embodiment of the invention, the pin has a thread at least partially on its outer circumference, into which a corresponding thread of a threaded spindle or the like engages. The screw spindle itself has an active point for a receptacle for an operating tool, which is arranged laterally next to the pin and projects into the gap between the door and the door frame.

In this case, the lower part of the pin which cooperates with the lower part of the shaft suspension is advantageously not threaded. The invention will now be described in detail with reference to the drawings.

It is assumed at the outset that the drawings only show those parts of the door or shaft suspension mechanism that are important for understanding the invention. All parts not shown and/or described in detail may have a known structure.

In FIG. 1, reference numeral 10 designates a door, to which is assigned a floor door check 11 of a known construction type, which is embedded in a floor 12 in a known manner.

Reference numeral 13 generally designates connecting elements between the floor door check 11 and the door 10. These elements may have a known construction and are likewise connected to the door 1 in a known manner. , collaborate with 0.

As can be seen from the upper half of Figure 1, the door l.

A lower part 14 of the shaft fishing mechanism is attached therein. A detailed explanation of the structure of the lower part 14 of the shaft fishing mechanism will be omitted.
Similarly, the method of attaching the portion 14 to the door 10 will be omitted.

The lower part 14 of the original shaft fishing mechanism is replaced by the upper part 15 of the shaft fishing mechanism.
It is only important that this upper part 15 of the fishing mechanism must be equipped with a receiving chamber for the pin of
The pin can be inserted into the receiving chamber of the lower part 14 of the pivoting mechanism and thus create a connection for the door 10, as will be explained later. If necessary, it is also possible to disconnect the pin by pulling it out of the lower part 14 of the shaft fishing mechanism.

The upper part of the shaft fishing mechanism is indicated generally at 15 and is housed in a ceiling or door frame 16 in a manner known and therefore not shown in detail. The structure of this upper part 15 of the fishing mechanism can be seen very clearly from FIGS. 2 and 3. The upper part 15 of the shaft fishing mechanism thus has a housing 17 with a receiving chamber 18 of approximately hollow cylindrical design. In a direction perpendicular to the casing 17, this casing 17. , has a fixed part 19 which is integral with the casing 17. In the embodiment shown, this fastening part 19 is plate-shaped and has different lengths in oppositely arranged areas with respect to the housing 17, as can be clearly seen in FIG. There is.

A threaded bushing 20 is arranged in the lower part of the receiving chamber 18 . This threaded bushing 20 is connected to the receiving chamber 18.
However, the retaining ring 21 prevents the threaded bushing 20 from moving in the axial direction. This retaining ring 21, as best seen in FIG. engaged within.

Therefore, the size and shape of both of these 9 notches are adapted to the retaining ring 21 used.

The threaded bushing 20 has a central through-hole, which is not shown in detail, and is penetrated by the through-hole 723. Inside the bottle 23, there is a first grooved bushing 24.
is fitted, and the grooved pin 24 engages in the thread groove 25 of the threaded bushing 20 at its front end, which projects from the pin 23. In this case, the pinch of thread groove 25 is relatively large, as best seen in FIG.

A pin 2 located outside the threaded bushing 20
A second grooved pin 26 is also fitted in the upper part of 3, which second grooved pin 26
The front free end of 6 is connected to the vertical slit 27 of the cage leg 17.
Since it is desired that the grooved pin 24 be held inward, the grooved pin 24 is made as long as the rim. This second slotted pin 26 prevents the pin 23 from pivoting, so that only an axial movement of the pin 23 is possible.The lower area of the pin 23, which projects from the threaded bushing 20, This is the area that cooperates with the lower part 14 of the shaft fishing mechanism. In the position of the bin 23 shown in FIG. 3, the bin 23 is in its lowest position.

The threaded bushing 20 (see Figures 4 and 5) is attached to the collar 2.
9, the collar 29 being arranged in a direction perpendicular to the longitudinal direction of the threaded bushing 20.

This collar 29 is provided with a notch 30, which has a substantially rectangular shape in plan view and is open toward the front. These cutouts 30 have the same shape as each other, so that the remaining areas of the collar 29 located between the cutouts 300 also have the same structure. The collar 29 is integrated with the threaded groove bunsh 20.

The 3° notch in the collar 29 of the threaded bushing 20 is useful for engaging tools. This tool is illustrated in FIGS. 6 and 7 and is configured as a hook 34. Meanwhile, the handle (not shown in detail) of the hook ξ 34 is connected to the hook 3 via a joint 36 with two bends.
It becomes clear that there will be a transition to 5. The structure and dimensions of this hook 35 are such that it fits into one of the notches 30 in the collar 29 of the threaded groove sink 20. The collar 29 of the threaded bushing 20 is advantageously made slightly thinner than the normal gap between the door and the door frame, but slightly thicker than the thickness of the hook ξ 34. . In this way, it is possible to rotate the threaded bushing 20 between the door and the door frame by the hook ξ 34 even when the door 10 is closed.

In order to prevent unskilled persons from manipulating the threaded bushing 20 or the bottle cooperating with the threaded bushing,
After the installation is completed, the fixing plate 32 is installed. This fixing plate 32 has a substantially rectangular shape, and in this case, a narrow protrusion 33 bent out from the pace plane is provided on one narrow side. This projection 33 is precisely adapted to the dimensions of the notch 300 in the collar 29 of the threaded bushing 20. In order to be able to omit a special or additional fixing member for attaching the fixing plate 32, a second
As can be clearly seen from the figure and FIG. 3, one of the screws 31 attaching the fixing part 19 of the upper part of the shaft fishing mechanism 15 to the ceiling or door frame 16 is also used to fix the fixing plate 32 at the same time. (・ru0 The mode of operation of the shaft fishing mechanism according to the present invention is as follows. That is, the hook 35 of the hook ξ 34 is engaged in one of the square notches 30 of the collar 29 of the threaded bushing 20. and then the key
The desired axial movement of the pin 230 is obtained by rotating the ξ 34. Indeed, as already mentioned, by rotating the threaded bushing 20 which is fixed so as not to shift in the axial direction, the first threaded bushing 24 and the high pinch inner threaded groove 25 can be rotated. , the bin 23 which is prevented from rotating again via the second grooved bin 26
can now be moved in the axial direction. In this case bin 2
3 can be recessed into the upper region of the receiving chamber 18 in FIG. Thereby, the front free end of the bin 23 emerges from the receiving chamber of the lower part 1 of the shaft fishing mechanism, not shown in FIG. From this end position, which is not shown, the pin 23 can of course be returned again to the other end position seen in FIG.

As already mentioned, the invention is, of course, not limited to the exemplary embodiment shown, but can be implemented in many different ways. This applies in particular to the construction of the threaded bushing 20 and the parts cooperating with it. For example, it is possible to provide the bottle 23 with a thread at least partially on its outer circumference. Such a screw can be engaged by a corresponding thread of a screw pin or the like which is arranged laterally next to the external screw, the screw pin being
It can be rotated via an operating tool whose active surface is located in the gap between the door and the door frame. In this embodiment, the lower range useful for connection with the lower part of the shaft fishing mechanism is completely 1,
・It is advantageous not to have screws・
