Description

The invention relates to a bearing part for a frame or a wing of a window, a door or the like, which can be applied to an abutment side of the bearing part to the frame or wing, wherein the bearing part at least one bearing elevation for connecting the bearing part with a hinge part and the bearing part at least a passage recess, into which a connecting means for fixing the bearing part to the frame or wing is insertable, wherein the longitudinal axis of the passage recess is oriented obliquely to the contact side.

It is known to use bearing parts on window frames or door frames or window sashes or door wings for fastening the sash to the frame. The bearing part can be used as a hinge for doors, windows or the like. The bearing survey is preferably formed in this case as a socket for receiving a hinge pin or a bolt. However, the bearing survey can also have a projection in the form of a hinge pin or the like for connection to a socket of the hinge part.

The bearing parts are often exposed to high stress. For example, if bearing parts are used to mount a sash on a frame, the sash exerts a high force on the bearing part. At the same time it is difficult to firmly and reliably connect the bearing part with the frame or wing, as they are often made of plastic or aluminum. Fasteners, such as screws, are often torn out of the frame or wing in these frames or wings. The longitudinal axis of the through-hole is therefore formed obliquely to the plant side, to allow a rear grip of the connecting means to the frame or wing. Nevertheless, it often happens that the connecting means are pulled out due to the spaced from the connecting means bearing elevation and the resulting leverage forces at high loads from the wing or frame, especially when the bearing part and the band member represent elements of a Scherenarmlagers, exhibited by a wing becomes. Furthermore, a secure attachment of the bearing part to provided in the frame or wing steel profiles is limited, since such steel profiles do not protrude into the miter of the frame or wing.

From the DE 7 145 404 U For example, a hinge is known which has a bearing part with a bearing projection which is encompassed by a projection of a hinge part. The bearing part has three through-holes, of which at least one through-hole is aligned obliquely to the contact side of the bearing part. A screw is passed through this through-hole to secure the bearing part. The passage recess is provided relative to the bearing survey. In the case of a load on the hinge therefore there is a risk that the screw is torn out by the levers acting on the bearing part.

From the DE 93 14 572 U1 Furthermore, a tape for doors, windows and the like is known, which has a bearing elevation, in which a bolt of a band part is guided. In addition to the bearing elevation, an oblique through-hole is provided in order to be able to arrange a bolt having a screw head for fastening the bearing part as close as possible to the bearing elevation. As a result, leverage forces can be reduced by the load of the bearing part on the bearing survey. Nevertheless, there is the risk that the screw is torn at very high loads of the bearing elevation due to the resulting leverage forces from the wing or the frame on which the bearing part is arranged by the screw, or stops the bearing elevation.

The CH 242 554 A discloses a hinge which is secured with a mandrel extending obliquely to the hinge axis. For secure attachment of the mandrel is threaded or countered by other securing means. The attachment of the hinge is therefore correspondingly expensive.

A similar hinge is also from the DE 912 902 B as well as the DE 197 48 418 A1 known.

Furthermore, the disclosure CH 276 647 A a hinge with an obliquely insertable into a wing or frame mandrel. The spike is countered by a nail in the wing or frame. The attachment therefore requires a certain effort.

Furthermore, from the DE 2 117 645 a door frame with mutually provided wall seal known. A mandrel of a door hinge is obliquely introduced into the door frame.

Furthermore, from the GB 2 474 046 A and the GB 2 458 935 A Known plates that are used for attaching pictures, clothes hooks, curtain rails and the like. The plates are fastened to friable materials by a connecting means guided obliquely through the plate.

Further, the WO 2011/032772 A1 a bearing part for attachment to a mounting wall. The bearing part has a bearing part body and a bearing elevation, on which a band part is mounted. The bearing body part has through holes, into which obliquely through the bearing part body guided connecting means can be introduced. The bearing part body is formed so solid that the oblique guidance of the connecting means is ensured.

Finally, out of the AT 324 882 B a mounting plate for furniture hinges has become known, which has two barb-like ridges provided with hollow expansion dowel on the plant side. Through the introduction of Spreizzapfen in the cavities of the expansion dowel, the mounting plate can be attached.

The invention is based on the object to provide a bearing part, which are material-saving and easily connected in a simple manner with a wing or frame and can absorb and deduce the weight of the wing optimal.

This object is achieved by a bearing part for a frame or wing of a window, a door or the like, which can be applied to an abutment side of the bearing part to the frame or wing, wherein the bearing part has at least one bearing survey for connecting the bearing part with a hinge part and the bearing part has at least one passage recess into which a connecting means for fixing the bearing part to the frame or wing can be inserted, wherein the longitudinal axis of the passage recess is aligned obliquely to the contact side and the passage recess extends at least partially in the bearing elevation.

A connecting means, in particular a screw, can be performed by the oblique through-hole in the bearing elevation and inserted into the frame or wing. The connecting means engages in this way the surface of the frame or wing and allows connection to the frame or wing, which is as close as possible to the connection point to the band part. As a result, a stable attachment of the bearing part with minimal leverage on the frame or wing is possible. Furthermore, the through-hole is additionally extended by the bearing survey, whereby a better adhesion between the bearing part and frame or wing is made possible via the connecting element.

The passage recess preferably has a round cross-section. The round cross section is optimally able to receive a screw or a similar connecting means with a round cross section.

In a preferred embodiment of the invention, the through-hole is provided in the region of a longitudinal end of the bearing part. The forces emanating from the band part can thus be diverted particularly well into the frame or wing.

The longitudinal axis of the passage recess is preferably formed at an angle of 30 ° to 60 °, in particular at an angle of 45 ° to the contact side. On the bearing part attacking tensile forces can be particularly well derived via the connecting means in the frame or wing. Furthermore, the connecting means introduced into the through-hole does not strike a steel profile arranged in the frame or wing, so that pre-drilling in the frame or wing for the connection means is unnecessary. Finally, the obliquely inserted connecting means engages behind a large area of the frame or wing, so that the risk of tearing the connecting means is minimized.

On the plant side, a projection, in particular a round cross-section pin, be formed. The projection is insertable into a recess on the frame or wing. The projection thereby enables a positive and / or non-positive connection between the bearing part and the frame or wing.

The passage recess preferably extends at least partially in the projection. Alternatively, a, in particular continuous, projection recess can be provided on the projection, which is aligned with the passage recess. This allows a particularly long through-hole. The connecting means can be guided so well. A pilot hole for the connecting means on the frame or wing is not necessary. Rather, a self-tapping screw can be used as a connecting means, which is optimally guided due to the long through-hole.

At least one connecting opening may be provided on the bearing part, the longitudinal axis of which is formed perpendicular to the contact side. Through the connection opening, a further connecting means can be introduced, which strengthens the connection between the bearing part and the frame or wing. The angle between the longitudinal axes of the connecting means inserted through the through-hole and the connecting means inserted through the connecting hole is preferably 45 °.

The connection opening preferably has a round cross section. As a result, a cross-sectionally round connecting means, such as a nail or a screw can be used.

The cross section of the connection opening may be slightly smaller than the cross section of a projection which is to be held by a press fit in the frame or wing. In the frame or wing holes of the same diameter can be drilled in this case for fixing the bearing part, wherein a hole for receiving the guided through the connection opening connecting means and a further hole for receiving the projection. A drill change during assembly of the bearing part is made unnecessary by the need of holes of the same diameter.

For particularly secure attachment of the bearing part a plurality of connection openings are preferably provided. The longitudinal axes of these connection openings and the longitudinal axes of all projections provided on the bearing part preferably intersect a straight line which runs in particular parallel to the longitudinal axis of the bearing part. For drilling the holes in the wing or frame drilling units, d. H. standardized drilling tools with equidistant drills or drilling templates. A uniform force transmission from the bearing part to the wing or frame can be achieved in that projections and / or connection openings are equidistant.

The longitudinal axis of the passage recess preferably points away from the longitudinal axis of the connection opening in the direction of insertion of the connection means. The connecting means inserted into the through-hole can hereby engage behind a region of the surface of the frame or wing which lies outside the contact side of the bearing part. As a result, a large-area connection of the bearing part is made possible with the frame or wing. The forces acting on the bearing part forces can be particularly well derived in the frame or wing.

The connecting means should not be visually visible for aesthetic reasons. Furthermore, bearing parts are often over-painted, the connecting means should not be swept over. The known bearing parts therefore have a cap or the like for covering the connecting means for the connecting means. However, such a cap can be damaged, fall off, scratched or lost. The through-hole therefore preferably has an enlarged cross-section on its opening facing away from the contact side. In this way, a widened end of the connecting means can be inserted into the through-hole and thereby be arranged completely in the through-hole. Due to the oblique orientation of the through hole, the connecting means is covered by the bearing survey and thus not visible from the outside.

In a preferred embodiment of the invention, the bearing part is formed symmetrically to a central plane of symmetry, which is perpendicular to the system side and perpendicular to the longitudinal side of the bearing part. The bearing part is thus suitable for a left and right stop. Furthermore, care must be taken during the assembly of the bearing part on the orientation of the bearing part. The bearing part can be fixed by a fitter with little effort.

Preferably, two passage recesses are provided at the two longitudinal end portions of the bearing part. The longitudinal axes of the passage recesses are preferably substantially perpendicular to each other. As a result, an optimal connection between the bearing part and the wing or the frame is made possible.

In a preferred embodiment of the invention, the bearing part on two bearing surveys, in which aligned alignment bolt receptacles are provided. The mutually aligned bolt receptacles allow secure two-sided support of a bolt for connecting the bearing part with the band part.

The bearing part can have at least one roller trough. This can serve to receive a roll of the band part surrounding a pin of the band part. The load of the wing can be so well supported. The bearing part is thereby formed in the form of a roller bearing part.

At least one connection opening can be formed in the roller recess. A bolt and / or a roller of the band part can hide the roller recess. As a result, an inserted into the connection opening connecting means to the outside is invisible.

The bearing part may be formed in one piece. Furthermore, the bearing part is preferably made of steel or manufactured as a die-cast part. As a result, the production costs and production costs can be significantly reduced.

In a particularly preferred embodiment of the invention, the bearing part in the region of a bearing survey on at least one insertion part. Through the insertion part, a bearing part body of the bearing part in a metal die-casting process, for example, a zinc die-casting process, are produced, can be dispensed with a machining (post) machining. By means of the insertion part may further be formed a part of a screw head seat for a connecting means in the form of a screw. The bearing part points preferably in the region of both bearing surveys each have an insertion part.

For particularly cost-effective production of the bearing part, the insertion part can be made of plastic.

At least one insertion part, in particular both insertion parts, may be insertable in the longitudinal direction into the bearing part body. The bearing part body can thereby be produced in an injection molding or die-casting process, wherein in the longitudinal direction a through-hole can be provided in at least one bearing elevation for receiving a bolt for connection to the band part. At least one open end of the through-hole can then be closed by the insertion part.

In one or both insertion parts one, in particular continuous, recess may be provided for receiving the bolt. The bolt can thereby be held securely in the bearing part. Furthermore, at least one insertion part can have a latching nose for securing the bolt. In the case of a groove extending around the outer surface of the bolt, it can lock in any rotational position of the bolt with the locking lug. Preferably, both insertion parts each have a recess for receiving the bolt and a latching lug.

At least one obliquely aligned to the contact side or trained Durchgangsausnehmung of the bearing part can be at least partially formed by a Einschubteilausnehmung. As a result, the through-hole without machining (re) machining, in particular without drilling or milling, produced. The through-hole can be made for example by two half-shell-shaped recesses, one of which is formed by the Einschubteilausnehmung. Preferably, both insertion parts each have at least one insertion part recess for the formation of passage recesses of the bearing part provided obliquely to the abutment side.

The invention further relates to a window, a door or the like with a bearing part described above.

Further advantages of the invention will become apparent from the following detailed description of embodiments of the invention, as well as with reference to the figures of the drawing, which shows essential to the invention details. The features shown there are not necessarily to scale and presented in such a way that the features of the invention can be made clearly visible.

In the schematic drawing two embodiments of the invention bearing parts are shown in various stages of use and explained in more detail in the following description.

Show it:

1b the bearing part 1a in a side view;

1c a partially sectioned view of the arrangement 1a along the line CC;

2 a sectional view of a second embodiment of a bearing part;

3a a sectional view of a third embodiment of a bearing part;

3b a perspective view of an insertion part of the bearing part according to 3a ; and

3c a sectional side view of the insertion part 3b ,

A first inventive bearing part 10 is in 1a shown. The bearing part 10 is by four connecting means 12a -D to a profile of a frame 14 assembled. The bearing part 10 is formed in the form of a roller bearing part. A band member is fastened to the bearing member by a bolt (both not shown) 10 held. For receiving the bolt, the bearing part 10 two bolt holders 16a . 16b on.

The bearing part 10 serves the pivotal connection of a wing and a fixed frame of a window, a door or the like and absorbs the weight of a wing. The weight of the wing is in 1a through an arrow 18 shown. Due to the weight of the wing, the connecting means 12b -D claimed to shear. The connecting means 12b -D are in a steel profile 20 of the frame 14 screwed.

The frame 14 points next to the steel profile 20 exclusively plastic or aluminum elements. Other connecting means, in the manner of the connecting means 12b -D in plastic or aluminum elements of the frame 14 are therefore prone to "tearing" by the weight of the wing. Furthermore, such fasteners tend to screw when screwing a "spin" by applying high torques.

For better attachment of the bearing part 10 at the frame 14 is therefore in the bearing part 10 a first through-hole 22a intended. The first through-hole 22a is diagonal to a plant side 24 of the storage part 10 aligned. In the present case, the through-hole is 22a below 45 ° to the plant side 24 educated. That into the through-hole 22a introduced connecting means 12a can thereby the tensile forces on the bearing part 10 optimally record. In the first through-hole 22a opposite longitudinal end portion of the bearing part 10 is a second through-hole 22b intended. By introducing a further connecting means (not shown) in the second through-hole 22b can the connection between the bearing part 10 and the frame 14 be further strengthened.

The passage recesses 22a , b run at least partially in camp surveys 25a , b. In the through holes 22a , b introduced connecting means, for example, the first connecting means 12a , can thereby be as close as possible in the area of bolt receptacles 16a , b are arranged. This creates a very secure connection between the bearing part 10 and the frame 14 scored, on the bearing part 10 over the bolt receptacles 16a , B acting leverage forces are minimized.

The bearing part 10 also has two projections 26a . 26b on, the material fit on the bearing part 10 are formed. By the formation of the projections 26a . 26b becomes a particularly secure connection between the bearing part 10 and the frame 14 allows. The passage recesses 22a . 22b are partly due to the protrusions 26a . 26b passed. The passage recesses 22a . 22b are thus made very long. In the through holes 22a . 22b introduced connecting means, for example, the first connecting means 12a , are characterized by the bearing part 10 well run. Despite the slope of the Durchgangsausnehmungen 22a . 22b must therefore no holes for the connecting means, for example, the first connecting means 12a which penetrate through holes 22a . 22b be introduced into the frame 14 be bored. Instead, self-tapping fasteners can be used. connecting ports 28a -C for receiving the connecting means 12b In contrast, -d are relatively short. For optimum guidance of the connecting means 12b -D are the connection openings 28a -C made round in cross-section.

How out 1b it can be seen, are the projections 26a . 26b essentially round in cross-section. The diameter of the cross section of the projections 26a . 26b is chosen so that for receiving the projections 26a . 26b Holes of the same diameter in the in 1b Profit not shown can be provided as for the connecting means 12b -D needed. The projections 26a . 26b have longitudinal axes 30a . 30b on. Furthermore, the passage recesses 28a . 28b . 28c longitudinal axes 32a -C on. The longitudinal axes 30a . 30b . 32a C intersect a straight line, not shown, parallel to the longitudinal axis of the bearing part 10 runs. The distance between the longitudinal axes 30a and 32a as well as between the longitudinal axes 32a and 32b as well as between the longitudinal axes 32b and 32c as well as between the longitudinal axes 32c and 30b is equal to. For mounting the bearing part 10 It can be used by a drilling device with five equal diameter drills, along the longitudinal axes 30a , b, 32a -C be introduced to the profile. Alternatively, a drilling template can be used in which the distance of the holes to the distance between the longitudinal axes 30a , b, 32a -C corresponds.

Around the bearing part 10 to use both left and right stop, is the bearing part 10 symmetrical to a plane of symmetry 34 formed perpendicular to the plant side 24 and perpendicular to the longitudinal direction of the bearing part 10 runs.

The partially cut representation of the bearing part 10 in 1c is removable, that the first connecting means 12a completely in the first through-hole 22a is arranged. The passage recess 22a has an enlarged cross section in the visible, the plant side opposite opening. Thus, the head of the connection means 12a completely in the through-hole 22a be introduced. There is therefore no cap or the like necessary to the first connecting means 12a to cover the outside. Furthermore, the connecting means 12b -D in the assembled state of the wing of the bolt of the band part (not shown) hidden. Also to protect the fasteners 12b -D are therefore no caps or the like necessary.

When exhibiting the wing particularly high forces act between the bearing part 10 ' and the frame, not shown, on which the bearing part 10 ' is arranged. The bearing part 10 ' has through holes 22a ' . 22b ' on. longitudinal axes 40a . 40b the Durchgangsausnehmungen 22a ' . 22b ' intersect at a right angle. At the warehouse part 10 ' As a result, attacking forces can be diverted particularly well into the frame. The bearing part 10 ' has warehouse surveys 25a ' . 25b ' on, in which mutually aligned bolt receptacles 16a ' . 16b ' are formed.

A bolt 42 of the band part 38 will be in the studs 16a ' . 16b ' guided. Between the camp surveys 25a ' . 25b ' is in the middle a roller trough 44 intended. In the roller tray 44 can matter 46 on the bolt 42 is arranged, turn.

The passage recesses 22a ' . 22b ' run at least partially in the bearing surveys 25a ' . 25b ' , This will be in the Durchgangsausnehmungen 22a ' . 22b ' guided connecting means, for example a connecting means 12a ' very well run.

A third bearing part according to the invention 10 '' is in a sectional side view in 3a shown. The bearing part 10 '' has a bearing part body 48 as well as in the area of two camp surveys 25a '' . 25b '' two insertion parts 50a . 50b on. Through the insertion parts 50a . 50b , which are made of plastic, the bearing body part 48 in a zinc die casting process without machining (post) machining. The insertion parts 50a . 50b be in the longitudinal direction of the bearing part 10 '' in the bearing body part 48 introduced.

Slanted to the plant side 24 ' provided through holes 22a '' . 22b '' of the storage part 10 '' are partially of substantially half-shell insertion Einschubteilausnehmungen 51a . 51b educated. As a result, a greatly simplified production of Durchgangsausnehmungen 22a '' . 22b '' allows.

The insertion parts 50a . 50b continue to show continuous recesses 52a . 52b in which a bolt 54 is introduced for pivotally connecting a belt part, not shown. To anchor the bolt 54 has this two annular grooves 56a . 56b on. In the ring grooves 56a . 56b are latching noses 58a . 58b the insertion parts 50a . 50b for securing the bolt 54 introduced.
