Description

Technical field:

The invention relates to a screw-on hinge for a vertical or horizontal a frame or wall pivotably arranged door or flap, in which the Door or flap is detachably held in at least one swivel angle position, consisting of a first z. B. hinge part attachable to the frame, and a second z. B. hinge part attachable to the door or flap, which Hinge parts are symmetrical about their median bisector and one each Include hole for receiving a hinge pin assembly, the Hinge pin assembly comprises a sleeve which is rotationally rigid with the one hinge part is connected and between which sleeve and the other hinge part one resilient locking device is arranged.

State of the art :

Such a screw-on hinge is described in US Pat. No. 5,412,842. By the Known hinge, it is possible to relative a door at a predetermined position to hold detachable to the frame when the door is for opening or Closing is pivoted. In the known arrangement are on the sleeve countersunk radial holes are provided, into which spring-loaded balls enter can. With the arrival of the ball, the sleeve and thus the sleeve connected hinge part (hinge flap) and thus in turn the door in the corresponding position held with a force by the spring tension and depends on the run-up angle of the ball. To take up the spring are in one Hinge part provided radially aligned to the hinge axis bore spaces open at one end to the sleeve and pick up the ball there while the other end of the hole can be closed by a slide which is then supported by the compression spring. The disadvantage here is that a special Configuration of the at least one hinge part (hinge flap) is necessary, which special configuration for an increased overall height of the hinge part leads. There are also a relatively large number of components in the citation embodiment shown there are a total of three balls, three compression springs and a retractable holding plate, which are necessary to achieve the desired result to reach. There are also difficulties with assembly, because balls, compression springs and plate can only be installed when the sleeve-shaped, with the Inlet openings for the ball-mounted hinge pin in place located within the two hinge parts. Another disadvantage of the ball is that punctiform pressure point, resulting in high surface pressure and fast Material wear leads.

DE 29 41 860 A1, which corresponds to the preamble of claim 1, is a hinge consisting of two hinge parts known in which the hinge pin is formed by a sleeve in which one Compression spring is arranged, which is provided with the end of the projections with the a hinge part torsionally rigid sleeve against one in the other Hinge part arranged, with radial notches insert presses to to obtain an elastic locking at certain angles of rotation. The disadvantage is that the two hinge parts are not axially fixable to each other and therefore the hinge only in connection with a second, opposite hinge Type can be used (p. 6, lines 16-21).

DE 24 18 147 discloses a hinge for a motor vehicle door with two through one Hinge pin centered hinge parts carrying interacting seat surfaces known. To determine in an open position, those with notches or Projections equipped seats by the door weight or by not closer explained springs (p. 2, line 14) pressed together. That encloses a hinge part the other forked.

DE 23 42 945 also describes a hinge for a motor vehicle door, the has a locking device. By a coil compression spring 10, which by a second Coaxially arranged compression spring 9 can be reinforced with radial Depressions provided, with the one hinge part 3 rotationally rigidly connected Control plates against pins 11, 12 which are guided transversely through the hinge pin 6 pressed which hinge pin is torsionally rigid with the other hinge part 1 are connected.

Two diaphragm spring assemblies facing each other and held by a screw shows the hinge of EP 0 266 490 B1, see Fig. 4, provided for a lockable vehicle door.

DE-OS 22 35 555 discloses hinge tapes for a hinge with locking Coaxial and arranged on the hinge pin (plate) springs (claim 2).

DE 31 26 933 A1 deals with a hinge for doors, the Rest positions possible. A locking force is exerted by the residual closing pressure (p. 7, line 11).

DE 36 24 649 A1 mentions a bolt 4 with compression and thus discloses this Rivet principle for a lockable hinge for motor vehicles.

DE 39 05 351 A1 explains a hinged door and also hinges Locking device, whereby according to column 2, lines 49-51 hinge parts and locking parts also made Plastic can be injection molded, as can one made of metal inject existing bearing journal into plastic.

DE 196 19 473 A1 mentions in connection with a detachable Door hinge with structurally combined door retainer in column 3, line 44 a plastic glider.

Most of the hinges known from the above publications leave Miss compactness, the spring devices are often visible and effective not only unaesthetic, but also represent dust catchers. Apart from the US 5,412 mentioned at the beginning, selected as the closest prior art 842 (and possibly DE 29 41 860 A1) does not describe any of the publications a hinge suitable for sheet metal cabinet doors.

Object of the invention:

The object of the invention is to avoid the above disadvantages and a Screw-on hinge to create the one mentioned has a simpler construction, is more compact in its outer shape, fewer individual parts includes, is largely symmetrical, and therefore easier to assemble, and that has a longer lifespan.

Solutions:

The object is achieved in that the hinge pin device is in two parts and that one end of a hinge part facing the other hinge part, the Forms locking device, and that the locking device from a sleeve end face is formed and includes an axially disposed within the sleeve coil spring.

These features make it possible to use the space of the hinge pin for the Use locking device and it is avoided that one of the screw-on hinge parts of the screw-on hinge must be used, which causes the problems outlined above. The sleeve face also provides a contour surface is available which has a locking device with a relatively lower Surface pressure enables what reduces material wear and the Lifetime of the hinge increased.

The symmetry of the hinge and its parts not only makes assembly easier, too a subsequent change of the door stop is made easier.

According to a development of the invention, the locking device comprises one at the end the hole for the hinge pin formed or arranged in the hinge part Shoulder or blind hole bottom surface in which depressions or elevations are provided for elevations or depressions of the sleeve face correspond, the compression spring the sleeve with its elevations or Depressions against the shoulder or floor surface with their depressions and Elevations (recesses, protrusions) presses. This represents a particularly simple one Measure to achieve the desired rest positions without it captive balls are used, which also when mounting the hinge too Fuss.

For reasons of simplified production, it is favorable if the torsionally rigid Connection between the one hinge part and the hinge pin by a tongue and groove device is obtained, or alternatively by non-circular, for example prismatic cross-sectional shape of the cross-section of the hinge pin on the one hand and the hole in the hinge part in which this hinge pin is to be inserted, on the other hand.

Giving the hinge pin the shape of a sleeve is not just about that Material saving advantages, but also facilitates the production of Projections and recesses on the end face of this sleeve-shaped Hinge pin. In addition, there are more to be described Embodiments special advantages, such as the possibility of accommodation Coil compression spring and a bolt or rivet.

A particularly stable and nevertheless simple form of a hinge is one those in which the one hinge part the other hinge part fork-shaped encloses, as can also be seen in the prior art. Especially at this form of hinge, it is favorable that the sleeve-shaped hinge pin is executed in two parts and one end of a hinge pin part, which End to the other hinge pin part, which carries the locking device. To increase the Latching force, it is favorable if according to yet another embodiment of the Invention on both hinge pin parts of the two-part hinge pin accordingly their ends are provided with locking projections or locking recesses, which in engaging corresponding recesses or protrusions from ring shoulders are formed in the hinge part bore in which the corresponding ends of the Hinge pin parts are included.

The other end of the hinge pin parts can then in the hinge pin hole of the other hinge part torsionally rigid, but possibly sliding in the axial direction be included. The sliding recording ensures that it can dodge in the axial direction while engaging and disengaging.

It is favorable if the spring device for the latching device also has two parts is executed, in particular the spring ends of a screw penetrating the spring parts can be held, whereby one spring on the head of the screw and the other spring on one on the Screw screwed nut could support. This has the great advantage that the force with which the locking devices exert the holding force, not from parts of the Hinge must be included and this additional hinge parts load, but by the screw, which otherwise has no holding function can be applied. By this measure, the stability of the Overall arrangement greatly enlarged. At the same time the two forks of the fork-shaped hinge part relieved of bending forces.

It has proven advantageous if the end face of the sleeve has four lugs (or Elevations) or depressions, the distance from each other Have 90 degrees. This results in particularly favorable conditions for Hinges that allow an opening angle of 180 °. With this arrangement namely a function possible in which both in the closed position, as in the 180 ° open position as well as a half opening angle of 90 ° Locking arises. It is also a good compromise between numbers the locking lugs on the one hand and the width of the lugs (protrusions) on the other hand what to a favorable compromise between stability on the one hand and holding power on the other leads.

The depressions or noses (projections) formed by the shoulder should also be in this case four times and a distance of 90 degrees to have. The coordination of these lugs (projections) or depressions with each other leads to a particularly stable hinge shape and a particularly high one Holding force in the different locking positions.

It will usually be beneficial to align the rest stops in such a way that a Lock position when the door or flap is in the closed position is reached. Alternatively, however, the latching device can also be designed such that the spring pressure of the coil spring within a small to the click point lying angle of rotation to a torque in the direction of the rest point leads, and that the orientation of a locking point for the closed position in such a way is taken that when the door or flap is closed, the rest point is not quite is reached and therefore there is a torque acting in the closing direction. As a result, the door is held in its closed position with a certain pressure so that there is no rattling or play movement, as might be the case, when the door is in the closed position exactly at the zero point of the rest position.

It will usually be convenient if the hinge parts are designed in such a way that they open mutually aligned fastening surfaces of the frame on the one hand and the door or Flap are screwed on the other hand.

Best ways of carrying out the invention:

In Fig. 1 is a screw hinge 10 for one vertically or horizontally on one Frame or a wall 12 door or pivotally arranged about an axis 14 Detect flap 16 in at least one swivel angle position, for example is releasably held in one of the positions shown in FIG. 4. The Screw-on hinge 10 consists of a first one, for example on the frame or on the wall 12 attachable hinge part 18, the attachment for example could be done by means of two axially offset countersunk screws 20, see corresponding countersunk holes 22 in Figs. 3 and 4. Corresponding Holes can be found in a second, e.g. B. on the door or flap 16 screw-on hinge part 24. Both hinge parts 18, 24 each have one Bore 26, 28, see FIGS. 7 and 9, into which a hinge pin device 30 is recordable.

2 the conditions can be seen again in a reduced representation, the solid line the closed door or flap can be seen within the wall or frame 12, and dashed at 90 ° pivots to show another position, which can be a releasably held position like. 2 may be a machine cover 12, and that Hinge 10 hold a flap 16 which can be pivoted about a horizontal axis is opened in the dashed representation in the horizontal direction and for example, access to the engine room allowed for maintenance purposes.

In contrast, FIG. 1 may represent a door 16 that is about a vertical axis 14 can be opened and closed, with sealing strips 32 are indicated, which are placed on edges of the frame or wall 12 and when the door 16 is closed, a tight one together with folds in the door Allow closure of the openings closed by the door 16.

To get this sealing effect safely, it is important that through the hinge 30 a certain contact pressure is generated, which with the invention Hinge arrangement is possible, as will be described.

3, the hinge pin arrangement 30 of two sleeve parts 34 ', 34 " formed, which are expediently constructed identically and in Fig. 11 in a Side view, in Fig. 12 in a view from below and in Fig. 13 in a view from are shown above. The sleeve part 34 has at its lower end 36 in FIG. 11 an axially aligned, radially projecting ledge or spring 38, which in a corresponding groove 40 can be received, which is in the area of the first hinge part 18 Hinge pin bore 26 formed in the area of the fastening tab 42 returns. This recessed groove 40 weakens due to this arrangement thus the first hinge part is only insignificant, this tongue and groove connection serves the sleeve 34 each in the bore 26 of the two ends of the To keep hinge part 18 rigid, but axially displaceable. The other end 44 has an annular end face in which four depressions offset by 90 ° 46 are arranged. The sleeve 34 forms an axial bore 48 which is close to the End 44 narrowed to a bore 50 of smaller diameter. In hole 48 A larger compression spring 52 can be accommodated, which is shown in FIG. 14 is shown and on the shoulder 54 formed by the narrowing to the bore 50 can support. The narrower bore 50 in turn allows one in FIG. 15 Pass screw bolt 56 shown, as in the following is described.

The upper end of the sleeve 34 with the end surface having the depressions 46 is receivable in a bore 28, which is in Fig. 9 with respect to the second hinge part 24 is shown. This hole also forms a first hole area larger diameter, the sleeve 34 rotatably and axially displaceably and a second bore region 60 forming an annular shoulder 58 smaller diameter, the diameter of which is sufficient to turn the shaft to be able to pass through the bolt 56. The annular shoulder 58 carries according to Fig. 10, a bottom view of the part of FIG. 9, four with respect to Hinge axis radially arranged, offset by 90 ° to each other, axially projecting Lugs or projections 62, their 90 ° coordinates with respect to the mounting plane 64 are aligned slightly offset, for example by -5 °, as by the angle in Fig. 10 becomes clear.

The first hinge part 18 is designed so that it with its two Legs 66 engages around the inner part 68 of the second hinge part 24, whereby after corresponding bores 26 of the two legs 66 of the first Hinge part 18 to the two existing, to the hinge part center 67th symmetrically arranged bores 28 of the second hinge part 24 are aligned. In this position can be from the outside in the bores 26 of the first hinge part 18th each a sleeve part 34 with its side 44 having the narrower bore 50 be inserted ahead until this side 44 in the bore 28 of the second Hinge part 24 has penetrated and fills, with component 34 at the same time its spring part 38 is aligned so that this spring 38 moves into the groove 40. This assembled position can be seen in Fig. 3. Then you can in the Insert a compression spring 52 into each of the two open sleeves, whereupon finally the screw bolt 56 shown in FIG. B. first through the lower one Compression spring and thus through the bore 26 of the hinge part 18 and the (lower) Bore 28 of the hinge part 24 is passed, then through the Bore 50 of the sleeve 34 arranged below, then through the bore 60 of the hinge part 24, then through the bore 50 of a second sleeve part 34, the is inserted in the opposite direction into the upper bore 28 of the hinge part 24, through a second compression spring 52 and thus through the bore 28 of the second hinge part and through the larger part of the bore 26 of the hinge part 18 is performed. In this position, the head 70 of the bolt 56 lies against the 3 at the lower end of the lower compression spring 52, and one now nut 72 screwed onto the upper thread of the bolt 56 form a Support for the upper end shown in Fig. 3 upper compression spring 52. Die Cylinder screw or the bolt 56 preferably has one Extension that the two included compression springs 52 under a certain Get tension and thereby the two sleeve parts 34 'and 34 "according to FIG. 3 with their depressions 46 having end faces moved towards each other and thus on the shoulders of the inner portion 61 of the second having the projections 62 Hinge part 24 are pressed. In the shifted by 5 ° for example 10, the projection 62 and the recess 46 fit exactly as shown in Fig. 5, and the hinge has one Rest position reached. This locking position is in the arrangement shown in Fig. 1 with respect to the hinge part 24 shifted 5 ° clockwise, thereby on the door leaf 16 is subjected to a certain pressure. Because the door frame this 5 ° shift does not allow, namely the semicircular, for example, migrates 5 on an example, obliquely extending Side surface of the trough-shaped recess 46 upwards and thus increases the Distance between the two components, as can be seen in FIG. 6. this leads to pressing the corresponding compression spring 52 together. The compression spring 52 tries to undo this movement and presses it Hinge part 24 in the clockwise direction and thus according to FIG. 1, the door in the closed position, see arrow 74.

Since this pressure or torque is generated simultaneously by two springs 52, the pressing force doubles.

The length of the cap screw 56 is expediently chosen so that it disappears within the hinge parts. The hinge gets one aesthetic appearance, since the built-in locking device is not visible.

In the embodiment shown, a hinge according to FIG. 4 is such trained that it shows locking points at -5 °, at 85 ° and at 175 °. In the Position -5 °, the frame or wall pushes the door into position 0 °, whereby Contact pressure arises. At the 85 ° position, the door stays in the open position, the door leaf projecting substantially perpendicularly from the fastening surface. Finally, there is another opening position, one at 175 ° Has rest point, the hinge shown here this large opening angle allows (see the dashed line in Fig. 4), since it is a 180 ° hinge is.

The cylinder screw 56 compressing the springs 52 enables through Tightening or loosening the nut 72 an adjustment of the pressure force and thus the Adjustment strength. You can do without this adjustability, instead of Cylinder screw 56 also a rivet of suitable length and diameter use, for example in the form of a hollow rivet, one of which is the rivet head Function of the screw head and its other rivet head that of the nut of the Cylinder screw takes over.

The hinge parts can be injection molded from metal or preferably from plastic. The locking surfaces, if made of plastic, result in low coefficients of friction. For higher ones Resilience can also be favorable, the locking surfaces from a metal part form, which is inserted or injected into the plastic.

It is also possible to make the hinge pin device out of two nested ones Build up sleeves, the outer, first sleeve being fixed to the one hinge part is connected (such as pressed, glued), so that this sleeve with respect to the Hinge is not axially displaceable in the assembled state. Within that first outer sleeve, the inner second sleeve is axially displaceable and rotatable. The one outer sleeve may then protrude radially inwards Ring shoulder which form a locking surface, while the other, inner sleeve the one on it forms a rotating, corresponding second locking surface, this sleeve in suitably rigid, but axially displaceable with the other hinge part connected is. The inner sleeve then contains the spring, which is the locking surfaces of the press the two sleeves together. The spring is penetrated by a retaining bolt or holding rivet, the latter possibly also in the form of a sleeve. This arrangement is special stable and enables a hinge with hinge flaps made of plastic, into which the e.g. sleeves made of metal are embedded, of particularly great strength.

Commercial evaluability:

The invention can be evaluated commercially in control cabinet construction.
