Definitions

  • the present invention relates to a door closer with a door closer housing, which has a housing opening which is closed by a lid.
  • Door closers are known, for example in the form of overhead door closers or floor door closers and serve to automatically close the wing of a door after its opening and subsequent release.
  • a closer element such as a closer shaft is movably mounted, which can be coupled to the wing or an associated frame of the door.
  • a closer drive can be accommodated as a closing spring, which provides the closing force.
  • the components to be accommodated in the interior of the door closer housing can be introduced via the housing opening.
  • the interior of a door closer housing is also filled with a damping fluid, which can also be done via the housing opening.
  • the housing opening is closed with the lid.
  • the lid must be tight and possibly fluid-tight.
  • the covers of door closer housings may therefore be bolted or pinned to the cover seat. However, this is associated with a relatively high manufacturing and assembly costs.
  • the cover has an elastically deformable and / or resilient holding section, by means of which the cover is clipped into a cover seat of the door closer housing and / or clamped or can be clipped and / or clamped.
  • the lid can then be placed in the context of the production of the door closer in a simple manner to the housing opening and clipped with appropriate force and / or clamped. A complicated screwing is not required. There are also no additional fasteners such as screws, pins, bolts or retaining rings necessary, whereby the manufacturing costs can be reduced. Due to the resilient action of the elastically deformable holding portion of the lid is securely held in the lid seat after insertion into the housing opening.
  • the elastically deformable holding portion can be designed relatively simple and is therefore easy to manufacture. It may be, for example, a strip, a tongue, a flange or a ring of an elastic material such as steel.
  • the lid can also be made entirely of an elastic material.
  • the production of a door closer can be considerably simplified by a cover which can be clipped into the cover seat of the door closer housing and / or clamped.
  • the lid is held exclusively by a clip and / or clamp connection in the lid seat. That is, it is preferred that no additional screw, pin or locking ring connections are provided for holding the lid in the lid seat. As a result, the production costs can be kept particularly low.
  • the cover may have a flat, the housing opening covering cover portion along the edge of the holding portion extends in particular in the circumferential direction.
  • the circumferentially arranged holding section ensures reliable securing of the cover section in the housing opening.
  • the holding portion may be formed flat.
  • the cover can be designed as a sheet-metal component. Deep-drawn sheet metal components may have a bottom, a frame and a flange. In a deep-drawn lid thus the bottom can form the cover portion, while the frame and the flange together form the holding portion.
  • the holding section can be formed completely circumferentially with respect to the cover section in the circumferential direction.
  • the holding portion may comprise a flange portion extending radially outward from the cover portion.
  • the flange portion Upon insertion of the lid in the lid seat, the flange portion is moved radially inwardly under elastic deformation of the lid, whereby a clamping action results.
  • the flange portion In the presence of a corresponding recess in the cover seat, the flange portion can move radially outward again after reaching the end position and thus bring about a latching or a clipping.
  • the flange portion may be inclined with respect to an areal extent of the deck portion. This means that a surface extension of the flange portion does not extend at an angle of 0 ° and not at an angle of 90 ° to the surface extension of the cover portion, but obliquely to this, for example at an angle of between 10 ° and 80 °, in particular between 30 ° and 60 °, in particular about 45 °. In an outward pressure on the lid, in particular by a hydraulic fluid in the door closer housing for damping a closing operation, this spreads due to the inclined flange portion in the lid seat, whereby the holding force is even increased.
  • a special embodiment of the invention provides that the flange portion comprises circumferentially distributed locking lugs, which are separated by respective interruptions or recesses. Such locking lugs allow a particularly simple clipping or locking the lid in the lid seat.
  • the holding portion has a peripheral to the edge of the cover portion skirt portion from which the flange portion projects radially outward.
  • a jacket section may extend at least substantially at right angles to the planar extension of the cover section.
  • the jacket portion may be formed by the frame. The shell portion may rest against an inner wall portion of the door closer housing, preferably by clamping, and thus increase the holding and sealing action.
  • At least one receptacle for engagement of the holding portion of the lid may be formed on the lid seat.
  • the holding section can clasp or snap into such a receptacle.
  • a receptacle serve as an end stop when inserting the lid into the cover seat and thus contribute to the simplification of the assembly.
  • such an end stop facilitates the correct positioning of the lid.
  • a groove and / or a shoulder may be provided in a housing wall section surrounding the housing opening of the door closer housing. Such a groove or such a shoulder may in particular be formed completely encircling.
  • a further embodiment of the invention provides that the cover has an excess, at least in sections, relative to the cover seat. As a result, there is a press fit, which improves the grip of the lid. In addition, the sealing effect is increased.
  • a sealing element to be clamped between the cover and the door closer housing may be provided.
  • the sealing element can be arranged on the cover or on the cover seat before final assembly of the door closer housing. If required, a plurality of sealing elements can be provided.
  • the clip-in and / or clampable lid supports the use of clampable sealing elements.
  • the sealing element may be arranged in a groove provided for the holding section of the lid or in a groove provided for the sealing element in the door closer housing. In such a groove, the sealing element is reliably held before merging the door closer housing and lid. In addition, the groove ensures always correct positioning of the sealing element.
  • the sealing element can also be arranged in a groove formed on the cover, in particular the holding section.
  • the sealing element can interact in particular in the region of the holding section with the lid.
  • the elastic holding portion then exerts a pressure on the sealing element and thus contributes to an increase in the sealing effect.
  • the lid may have a cup-like shape. This allows a particularly simple construction.
  • the lid is formed as a deep-drawn part.
  • deep-drawing enables particularly simple, rapid and cost-effective production.
  • the holding section can be easily produced by deep drawing, for example as a frame and / or flange.
  • the lid and the lid seat can be made of different materials. This can in particular increase the sealing effect.
  • the materials are preferably selected specifically with regard to a sealing effect to be achieved.
  • the door closer housing may have an elongated shape, wherein the opening is located on an end face of the door closer housing.
  • the lid may then extend across a longitudinal axis of the door closer housing. It can also be provided on both end faces of an elongated door closer housing closable housing openings.
  • the door closer housing may be formed as a fluid-filled hydraulic cylinder, in which a displaceable piston of the closer drive is guided.
  • the lid can be designed in this case as a cylinder cover.
  • the cover in a plan view may be round, in particular circular.
  • the invention further relates to a system and / or arrangement comprising a door closer housing and a lid, wherein the door closer housing has a housing opening which is closed by the lid, and wherein the lid has an elastically deformable holding portion, by means of which the lid in a lid seat of Door closer housing is clipped and / or clamped. Described further developments relate both to the door closer according to the invention and to the system / arrangement according to the invention.
  • door closer 11 may be formed as a top door closer or as a floor door closer and includes an elongated door closer housing 13 in which a not shown, coupled to a door of a swing door closer shaft is rotatably mounted.
  • the door closer housing 13 forms a filled with a damping medium hydraulic cylinder, in the interior 15 a against the biasing force of a closer spring displaceable piston 17 is guided.
  • a not shown, fixed to the closer shaft pinion engages in a rack of the piston 17 and ensures that upon rotation of the closer shaft, a displacement of the piston 17 and vice versa.
  • the door closer housing 13 has an in Fig. 1 upper end face on a housing opening 19 which is circular here according to the cross section of the interior 15.
  • the housing opening 19 is closed by a cover 21, which is held in a cover seat 25 of the door closer housing 13.
  • the in Fig. 1 shown in a vertical orientation door closer 11 mounted horizontally.
  • the lid 21 is designed as a deep-drawn part of an elastic material, preferably made of sheet steel, and accordingly has a cup-like shape. Specifically, a bottom of the cup-like lid 21 forms a flat, preferably flat cover section 27, which covers the housing opening 19. As in particular from the individual representations of the lid 21 according to Fig. 5 and 6 shows, around the edge 28 of the cover portion 27 encircling shell portion 29 extending transversely to the cover portion 27, here cylindrical side wall. Starting from the upper edge 30 of the jacket section 29 in the picture, a flange section 31 protrudes radially outward, which at the in Fig. 1 embodiment shown by a plurality of circumferentially distributed locking lugs 33 is formed. The latching lugs 33 are separated from one another by respective recesses 35 extending to the jacket section 29. As illustrated, the detents 33 are each inclined with respect to an areal extent of the deck portion 27.
  • a first, inner groove 39 and a second outer groove 40 parallel thereto is formed in a housing wall opening 19 surrounding the inner wall portion 37 of the door closer housing 13. Both grooves 39, 40 are circumferentially completely formed circumferentially.
  • a sealing element 45 in the form of an O-ring made of an elastic material.
  • the sealing element 45 is further clamped between the shell portion 29 of the lid 21 and the inner wall portion 37.
  • the jacket section 29 thus forms, together with the latching lugs 33, a holding section 47 which extends in the circumferential direction along the edge 28 of the cover section 27.
  • the holding portion 47 is elastically deformable. It is thus possible to insert the lid 21 along a mounting direction M in the housing opening 19, wherein the locking lugs 33 are bent radially inwardly. Once the locking lugs 33 the outer groove 40 have reached, they snap into this and hold the lid 21 in the lid seat 25 firmly. At the same time, the jacket section 29 presses against the sealing element 45 located in the inner groove 39, so that a fluid-tight fit of the cover 21 is ensured. As a result, the cover 21 is clipped into the cover seat 25 and held in the cover seat 25 in a fluid-tight manner exclusively by the clip connection.
  • Fig. 2 shows a second embodiment of the invention, which is designed similar to that in Fig. 1 shown embodiment, which is why like-acting components are denoted by the same reference numerals.
  • the holding portion 47 'of in Fig. 7 and 8th has no latching noses. Rather, the flange portion 31 'of the holding portion 47' in the circumferential direction completely around the upper edge 30 of the shell portion 29 circumferentially formed.
  • groove 50 is formed in the inner wall portion 37 'in the region of the cover seat 25' only a single, here opposite to the in Fig. 1 shown outer groove 40 widened.
  • groove 50 is formed in a lower portion of this widened groove 50.
  • a sealing element 45 is arranged, which, moreover, as in connection with Fig. 1 described sealing element is executed. The sealing element 45 thus directly adjoins the flange portion 31 '.
  • the flange portion 31 'of the holding portion 47' is also formed completely circumferentially in the circumferential direction.
  • a single groove 50 is formed, which is not widened here.
  • the lid 21 ' is in principle designed as in Fig. 2 .
  • Fig. 7 and Fig. 8 shown lid 21 ', except that it has a shortened skirt portion 29.
  • the cover 21 ' also has an excess of the groove bottom 51 of the groove 50, so that the cover 21' is held with a press fit in the door closer housing 13. The press fit ensures a sufficient sealing effect, so that it is possible to dispense with a separate sealing element.
  • the sealing effect is also reinforced by the fact that the lid 21 'and the inner wall portion 37' made of different, with respect to the sealing effect selected materials are.
  • the flange portion 31' spreads into the groove 50, so that the holding and sealing action is further enhanced.
  • the cover 21 ' is thus held in the cover seat 25' of the door closer housing 13 both by a clip connection and by a clamping connection.
  • Fig. 4 shows a fourth embodiment of the invention, in which instead of one or two grooves, a slanting step 55 is formed in the inner wall section 37 ", the cover 21" does not have a jacket section in this embodiment.
  • the flange portion 31 ' which is in turn formed completely circumferentially in the circumferential direction, directly from the edge 28 of the cover portion 27 from.
  • the cover 21 has over the inner wall portion 37" of the door closer housing 13 on an excess, so that the lid 21 "as in the embodiment according to Fig. 3 is held with a press fit in the door closer housing 13.
  • the press fit not only provides such a pronounced sealing effect that it is possible to dispense with a separate sealing element, but holds the lid 21 "without latching, ie the flange section 31 'forms an elastically deformable holding section 47".
  • the sealing effect is reinforced by the fact that the cover 21 "and the inner wall section 37" are made of different materials which are specially selected with regard to the sealing effect.
  • a clip-in and / or clampable lid has the advantage over lids to be screwed or pinned on, that not only the assembly is simplified, but that in addition to separate attachment means can be completely dispensed with.
  • the design allows as a sheet metal part and in particular as a deep-drawn part a particularly cost-effective production.
