Abstract

In the proposed door or window hinge plate, the spigot component (1) on which the sleeve (2) is placed is provided with a spigot (5) which is mounted in such a way that its height can be altered. An adjustable element (7) in the form of a cap screw (19) engages in a thread (17) cut inside the spigot (5). Axial movement of the adjustable element (7) is prevented by an elevation (15) which protrudes radially into the bore (14). In addition, elevations (15) engage in a groove (11) in the spigot (5), allowing the spigot (5) to move axially but not to rotate. A tool can be inserted through an aperture (22) at the lower end of the spigot section (1). This tool can engage in an inner recess (21) in the adjustable element (7), thereby facilitating adjustment of the height of the spigot (5).

Description

Subject: door or window hinge

The invention relates to a door or window hinge with a pin part and a sleeve part, the pin of the pin part being held adjustable in height, the pin being displaceable in the axial direction thereof, and an adjusting part which is designed to be screwed and aligned axially with the pin and rotatably mounted in the pin part is provided.

Such a door or window hinge is known from DE 31 04 973 A1, which will be discussed further below.

Such door or window strips have one or more radially freely projecting threaded bolts both on the pin part and on the sleeve part, which engage on the one hand in the door or window frame and on the other hand in the door or the window itself. In order to be able to make an exact height adjustment after assembly of the door or window hinge or at a later point in time, the pin of the pin part is designed to be height-adjustable, so that the sleeve part can be raised more or less than the pin part. This allows the door or window hinge to be adjusted in the direction of the axis of rotation.

A hinge band has already become known, in which the pin is provided with an external thread and the pin part with an internal thread, so that the height of the pin has to be turned more or less into the pin part. The set position can be fixed using appropriate locknuts. These locknuts are visible from the outside between the two parts of the door or window hinge (CH-PS-654 063). So that a fixation of the pin can be achieved at all, a lock nut is required here in any case, which must be driven with the appropriate effort. A similar known design is provided for a hinge for doors, windows and the like (CH-PS-383 202). In this version, too, a threaded pin is screwed into a threaded hole in the pin part, the height adjustment being fixed by a corresponding lock nut. The only advantage over the aforementioned embodiment is that the sleeve part has a larger recess on its lower side in order to cover the nut or lock nut. Another possibility of height adjustment (AT-PS-168 988) provides for a pin which is fixed in the pin part and on the free end of which a screw which is held in the sleeve part and supports the same axis is supported. By turning this screw, a height adjustment of the sleeve part of the door or window hinge is of course also achieved, but such an adjustment is always visible from the outside and can be operated by anyone without any problems.

Another known arrangement (AT-PS-383 389) is about a drilling pin band, in which a pin designed as an axis boating is supported on a height adjustment screw with a conical end face. The screw head also has a conical surface, so that when the screw is screwed in, the pin is raised more or less in relation to the axis of rotation in the radial direction. This adjustment unit is easily visible from the outside and can therefore be adjusted again at any time. Securing the set altitude is at least attempted by pressing a threaded bolt into a corresponding opening on the circumference of the pin. If, however, the height adjustment screw becomes loose, the pin can move downward under the load on the suspended door or window, so that the height adjustment is lost.

In the door or window hinge known from DE 31 04 973 A1, attempts are made to secure the set altitude by providing a brake ring around the adjustment part designed as a screw.

The present invention therefore has for its object to provide a simple, effective and self-locking adjustment for the pin of the pin part of a door or window hinge of the type mentioned.

This object is achieved in that the pin is secured against rotation in the pin part, that the adjusting part is secured against axial displacement in a hole provided in the pin part, and that the pin and the adjusting part are coaxial with the axis of rotation Threads are in mutual interaction. According to the invention, a simple adjustment of the screwable adjustment part makes it possible to adjust the height of the pin which is displaceably guided in the axial direction, the pin not being able to rotate with the adjustment part due to this special guide. In addition, since it is ensured that the adjustment part cannot move axially, it is ensured in a simple manner that when the adjustment part is rotated there is an axial movement of the pin, since the adjustment part itself only rotates, but not in the axial direction can move. With such a construction, a simple, captive preassembly of such door or window strips is also possible, a simple, but safe and always self-locking adjustment possibility being always provided on the spot. If only because the pin is always supported on the adjustment part by the axial load on it, the adjustment part cannot twist by itself due to the weight that has arisen.

A special embodiment variant provides that the pin has at least one axially parallel groove or a projecting web on its lateral surface, and that on the wall of the bore provided for receiving the pin in the pin part at least approximately correspondingly designed or arranged webs, elevations or Grooves are provided. These constructive measures ensure reliable guiding of the journal in its axial direction, so that it is ensured that on the one hand easy displacement in the axial direction but on the other hand a reliable prevention of rotation is ensured.

It is further proposed that the pin at its end ripening into the pin part is provided with one or more grooves running axially parallel, which open out towards the end of the pin. As a result, a very specific embodiment has been created which enables such a pin to be replaced if necessary. By turning the adjustment part for a correspondingly long time, the pin can thus be raised until the mutual thread engagement between the adjustment part and the pin is eliminated. Then the pin can simply be pulled upwards out of the hole in the pin part, whereas the adjustment part itself remains in its position in the pin part.

In this context, an expedient embodiment provides that the pin has two grooves arranged at 180 ° to one another at its end which engages in the pin part. The pin can then be inserted into the pin part in two positions offset by 180 °. A single groove would be sufficient for reliable displacement guidance and securing against rotation of the pin, but for manufacturing reasons it makes more sense to provide two mutually opposite grooves which can be produced in a simple manner by a pressing or milling process.

For this purpose, it is particularly advantageous if the groove (s) is or are limited in cross section in the form of a circular arc. Such training is particularly advantageous for production. A special variant is given if an elevation is provided on the wall of the bore in the pin part or two or more consecutive axially protruding elevations in the form of knobs or the like are provided in the axial direction. It is sufficient if these knobs or the like simply protrude a small distance into the interior of the bore in the pin part, because these knobs or the like should only create the possibility that the pin can move in the axial direction, but is secured against twisting. Therefore, only such an elevation in the form of a knob or the like would be sufficient, but the arrangement of two or more than two such knobs or the like makes sense particularly when larger adjustment paths are necessary.

The most expedient embodiment variant provides that the pin has a threaded bore at its end engaging in the pin part, into which the threaded shaft of a head screw forming the adjustment part engages. Such a design can be designed in accordance with the measures according to the invention. This special construction alone ensures self-locking, since the corresponding forces rest securely on the head of the screw when the pin is loaded, so that the screw does not twist by itself, not even in the event of vibrations.

In addition, the head of the screw also acts as a corresponding guide part for the pin if it is provided that the head of the screw acting as an adjusting part has the same diameter as or a slightly smaller diameter than the pin. Thus, the bore in the pin part can have the same diameter throughout, since the adjustment part designed as a screw and the pin itself form an approximately uniformly continuous unit in outer diameter.

So that there is also a very simple possibility of adjusting the pin, it is proposed that the adjusting part be provided with a central, internal end engagement for attaching a tool, and that the pin part have an equiaxed opening at the bottom of the bore for inserting the tool. It can therefore be accessed from below with a tool in the pin part to bring about a height adjustment of the pin. It is also advantageous that this adjustment option is not particularly apparent from the outside, so that an intentional, unauthorized adjustment will hardly ever occur. In addition, it is easily possible to close this additional opening for inserting the tool by means of a plug-in part, if this is expedient. In a special embodiment it is provided that the elevations on the wall of the bore are formed by the ends of radially screwed in or hammered in pins or bolts or by knobs produced by deformation of the wall. There are therefore several options available for creating the above surveys. It is easy to make these elevations through the ends of pins or bolts that can be inserted from the outside. However, to ensure that the pin can always be easily adjusted in the axial direction, these pins, bolts or knobs must not strike the surface of the pin or in the groove thereof, since otherwise the adjustment movement would be made more difficult. These pins or bolts must therefore be secured accordingly. In the formation of knobs produced by deformation, there is always the guarantee that only correspondingly large elevations are formed.

The door or window hinge according to the invention can be manufactured in various ways. One variant provides that the pins, bolts or knobs are inserted or molded in after the unit formed from the pin and adjusting part has been inserted. This makes it possible to use this unit after the preassembly of the pin and adjustment part and then to fix it by screwing in or driving in the pins or bolts or by molding in the knobs, with such a method of production taking care that the grooves are in the correct position in the pin and the adjustment part stands exactly on the bottom of the hole in the pin part.

As such, it is also possible to initially only use the adjustment part, whereupon the pins or bolts are placed or the knobs are deformed. Then only the pin has to be inserted, and by turning the adjustment part the pin can then be pulled into the bore of the pin part.

Embodiments of the invention are explained in more detail in the following description with reference to the drawing. Show it:

1 shows a section through the pin part of a door or window hinge.

Fig. 2 is a view of the sleeve part;

Figure 3 is a view of the pin, partially cut away.

4 shows a section along the line IV-IV in FIG. 3rd The door or window hinge essentially consists of a pin part 1 and a sleeve part 2, both parts being equipped with a radially projecting threaded bolt 3 or 4. These threaded bolts 3 and 4 are fixedly arranged here on the respective pin part 1 or sleeve part 2. In the case of a rotatable arrangement, it is also possible to arrange further such threaded bolts on these parts or, in addition to a threaded bolt, a correspondingly smooth bolt which can additionally contribute to the transmission of force or to the precise alignment.

A pin 5 is arranged in the pin part 1, which protrudes beyond the pin part 1. A bore 6 corresponding to the pin 5 is provided in the sleeve part 2, into which the pin 5 engages when the door or window hinge is used as intended.

In order to create a possibility for height adjustment of the pin 5 during assembly or during subsequent correction work, a special configuration is provided. The pin 5 is displaceable in its axial direction, but is secured against rotation in the pin part 1. An adjusting part 7 designed as a screw is aligned with the journal and secured in the journal part 1 against being axially displaced. However, the adjustment part 7 is rotatably mounted.

The pin 5 and the adjustment part 7 are mutually operatively connected via a thread 9, 10 coaxial with the axis of rotation 8.

The pin 5 has on its outer surface at least one axially parallel groove 11, but preferably two grooves 11 and 12. Of course, more than two such grooves 1 1 and 12 are also conceivable.

On the wall 13 of the bore 14 in the tap part 1, two elevations 15 are provided, which follow one another aligned axially parallel to one another. As can be seen particularly in FIGS. 3 and 4, the axially parallel grooves 11, 12 open out towards the end of the pin 5. These grooves 11, 12 are advantageously delimited in the form of a circular arc in cross section.

The elevations 15 projecting radially from the wall 13 of the bore 14 can be produced, for example, by reshaping in the corresponding area of the pin part 1. Using a suitable tool, the outer circumference of the sleeve is Pin part 1 corresponding to the number of elevations 15 grooves 16 pressed, which then cause the corresponding elevations 15 inwards.

As already stated, the pin 5 has, at its end engaging in the pin part 1, a threaded bore 17 into which the threaded shaft 18 of a head screw 19 forming the adjusting part 7 engages. The head 20 of the screw 19 acting as the adjusting part 7 has a diameter that is equal to the diameter or only slightly smaller than the diameter of the end of the pin 5 protruding into the pin part 1.

The adjusting part 7, in the present case the screw 19, is provided on the head 20 with a central, internal attack 21 on the end face. The pin part 1 is provided at the base of the bore 14 with an opening 22 aligned coaxially with this bore 14, which is used for inserting a tool which can then be attached to the inner engagement 21 of the adjustment part 7.

The elevations 15, which form a kind of knobs, have the effect that the adjusting part 7 is not axially displaceable, but can easily rotate in the area below the lower elevation 15. The elevations 15 also engage in the groove 11, whereby elevations lying opposite one another could also engage in the groove 12. This results in an axial guidance for the inserted pin 5, so that this pin 5 can thus be adjusted in the direction of the axis of rotation 8, but is secured in the direction of rotation. For this purpose, the elevations 15 engage in the groove 11. With a corresponding adjustment movement, it can happen that only the upper elevation 15 engages in the groove 11, but this is not a problem since a further elevation 15 projects into the groove 11.

For the manufacture of such a door or window hinge, the adjustment part 7 can initially be inserted into the bore 14, whereupon the elevations 15 designed as knobs can be pressed in by a forming process. But it would also be conceivable that the entire unit formed from the pin 5 and the adjusting part 7 is inserted into the bore 14, but care must be taken to ensure that the pin 5 is aligned with the groove 11, and that the elevations are then pressed in accordingly 15 are manufactured. In a further embodiment, the elevations 15 could be made before the adjustment part 7 and the pin 5 are inserted, but then an axial groove would have to be additionally provided on the head 20 of the adjustment part 7 so that the unit is inserted in an appropriately aligned manner could. Corresponding security against loss is ensured even with such an arrangement, namely for inserting the pins 5 and Adjustment part 7 formed unit, the mutual thread is not tightened, but, for example, after inserting the entire unit, a quarter turn of the adjustment part 7 is sufficient to fix the two parts to one another. In this position it is already ensured that the entire unit can no longer be pulled out by the corresponding adjustment of a groove provided in the head 20 of the adjusting part 7.

Instead of the elevations 15 produced by deformation, it would also be conceivable to provide corresponding bores or threaded bores into which bolts are driven or studs or other screws are screwed. These bolts or pins should only be driven or screwed in so far that their ends probably engage the grooves 1 1 or 12, but do not impair the axial displaceability of the pin 5. Bolts or pins used in this way could be fixed in their position by gluing, welding, soldering or simply by clamping in order to thereby permanently secure the adjusting part 7 against loss and also always provide a corresponding longitudinal guide for the pin 5 to have.

In the embodiment shown and described, one or more grooves and corresponding radially protruding elevations 15 are provided on the pin 5 and on the wall 13 of the bore 14 in the pin part 1. Of course, different designs of webs, ribs or grooves are also conceivable both in the wall 13 of the bore 14 and on the outer circumference of the pin 5. It would also be possible for corresponding elevations or webs on the pin 5 and a corresponding groove on the wall 13 of the bore 14 to be formed.

In the above description, only one exemplary embodiment was also explained, in which the screwable adjustment part 7 is designed as a cap screw 19. It would be quite conceivable to screw the adjustable part in the sense of a nut, e.g. a sleeve-like nut, the lowest section of the pin 5 would then have to be provided as a bolt with an external thread. The securing of the adjusting element against axial displacement and the securing of the pin 5 against twisting must then be solved in a structurally different manner, but it is always possible to work with appropriate grooves, webs, elevations or the like.
