Definitions

  • the invention relates to a hood holder on covers for door closer housing, which is held in the installed position on the cover and on the door closer housing and has at least one retaining spring for supporting the cover on the door closer housing.
  • hood holders are used for releasably attaching covers to door closer housings, the covers in turn protecting the door closer housing and the door closer transmission contained therein against environmental influences or contamination and giving the door closer system an attractive appearance.
  • hood holders with a ring-like base body and diametrically extending and axially elastic plastic leaf springs are used.
  • a bearing journal projecting in the axial direction is attached in the area of intersection of the diametrical leaf springs.
  • the known hood holder with the ring-shaped base body is pushed onto a projection on the end face of the door closer housing in question.
  • a bearing journal also projects axially from the opposite end face of the door closer housing.
  • the cover is provided on its faces assigned to the end faces of the door closer housing with receiving openings for the two bearing journals described.
  • the cover hood is placed on the opposite front face of the housing at an angle to the mounting plane of the door closer housing and then moved so far in the longitudinal direction of the door closer housing until the bearing pin protruding from this end face into the mounting hole of the assigned one Cover surface engages.
  • the free end of the cover hood is then pivoted against the mounting plane of the door closer housing and at the same time the bearing journal of the hood holder is pressed against the action of the leaf springs in the direction of the end face of the door closer housing by means of an assembly aid, for example a screwdriver.
  • the cover hood can be against the mounting plane of the door closer housing be pivoted into their end position.
  • the bearing pin of the cover holder engages in the receiving opening provided for this purpose on the associated end face of the cover.
  • the cover is held by the two bearing pins projecting axially from the door closer housing.
  • the design of the known hood holder requires, on the one hand, the assembly process described above and, on the other hand, only a selective mounting of the mounted cover hood on its end faces.
  • the cover hood can rotate relative to the door closer housing about the bearing journal of the hood holder or the opposite end face of the door closer housing which forms an axis of rotation. Because of the play in these cases, undesirable rattling noises can occur, in particular when the door closer system is shaken, as occurs, for example, when the door in question locks.
  • the object of the invention is a corresponding development of the known hood holder.
  • the cover on the door closer housing is rotatably mounted and the retaining spring (s) is (are) releasably locked in the installed position on the door closer housing. Due to the rotationally fixed mounting of the cover on the door closer housing, undesired relative rotational movements of the two components as well as any rattling noises associated therewith are avoided. Since the door closer housing itself is firmly attached, play-free storage of the cover relative to its surroundings is ensured by the non-rotatable mounting of the cover on the door closer housing.
  • the latching ability of the retaining spring on the door closer housing permits simple assembly and, with a corresponding design of the latching connection, also simple disassembly of the cover hood. The cover can thus be pushed onto the door closer housing with one hand and automatically fixed in its installed position.
  • hood holders In the case of hood holders according to the invention on cover hoods for door closer housings arranged on a base surface, in a further development of the invention it is provided that the retaining spring (s) supports the cover hood against the base surface of the door closer housing.
  • hood holders ensure that the cover abuts the base surface of the door closer housing at its edge encircling the opening.
  • the rotatable mounting of the cover on the door closer housing is therefore effected by the retaining spring (s) themselves. This is expediently associated with a stable support of the covering hood which is secured against undesired slagging.
  • a preferred embodiment of the hood holder according to the invention is characterized in that the retaining spring (s) supports the cover hood under pretension. Because of their pretension, the retaining spring or the retaining springs of such a hood holder are able to compensate for manufacturing tolerances on the components to be supported against one another.
  • a hood holder according to the invention on cover hoods for cylindrical door closer housings advantageously has at least two resilient locking tongues as retaining springs, which are supported in the installed position on the outer surface of the door closer housing at a distance from one another in the circumferential direction of the outer surface.
  • the use of two retaining springs requires a stabilizing two-point support of the cover hood on the door closer housing which counteracts a slag play. If the cover also comes into contact at other points, for example the door closer housing and / or an existing base area of the door closer housing, play-free storage of the cover is guaranteed.
  • the resilient latching tongues support the assembly of the cover hood with appropriate training.
  • the latching of the retaining springs on the respectively associated door closer housing is preceded by a sliding movement of the end of the respective retaining spring facing the door closer housing along the housing surface.
  • a corresponding sliding contact between the retaining springs and the door closer housing results when the cover hoods are removed. So that the friction occurring in the described sliding movements on the contact surface of the retaining spring and the door closer housing is reduced to a minimum, it is provided in a further embodiment of the invention that the retaining spring (s) is rounded at the end acting on the door closer housing, preferably with a cylindrical cross section is (are).
  • a play-free mounting of the cover on the door closer housing can be achieved in that a support secured against undesired relative movements is provided between the hood holder and the door closer housing and at the same time between the hood holder and the cover.
  • the fixing of the hood holder on the door closer housing serves that - as provided in a further embodiment of the invention - the hood holder is positively supported in the installed position on a contact surface on a counter surface of the door closer housing.
  • the hood holder is supported flat on the cover and / or via resilient positioning arms.
  • the support surfaces of the hood holder according to the invention, as well as their resilient positioning arms facilitate the assembly of the cover hood, for example by forcing the hood holder and cover hood into their desired position relative to one another during the pre-assembly of the hood holder.
  • the assembly work is further facilitated in that the hood holder is held clamped to the cover.
  • the clamp connection of the hood holder and cover hood also allows the cover hood to be removed at any time without the use of assembly aids.
  • cover hoods should also be as easy as possible to attach to door closer systems in public buildings. At the same time, it should only be possible to remove the covers, for example to protect against vandalism, under difficult conditions.
  • an embodiment of the hood holder according to the invention is intended, in which the hood holder has a locking projection projecting in the longitudinal direction of the door closer housing and projecting in this direction and is detachably locked to the cover hood by a locking receptacle provided on the associated end face of the cover hood and which is characterized in that the hood holder supports the cover, which is locked with it, via the retaining spring (s), locked against being pulled off the door closer housing, on the latter.
  • the cover hood can be attached in the simplest way, as already described above, for example by pushing it onto the door closer housing with one hand.
  • a corresponding removal of the structural unit consisting of the hood holder and the cover hood from the door closer housing is prevented by the retaining spring (s).
  • an assembly aid such as a screwdriver, with which the latching projection of the hood holder which engages in the end face of the cover can be pressed into the interior of the cover and thereby release the locking existing between the cover holder and the cover. Only then can the cover hood be separated from the hood holder that is still in the installed position.
  • hood holder is essentially U-shaped in cross section, the web surface of the hood holder being an end face of the cover hood and the corresponding end face of the Door closer housing is assigned, a resilient locking tongue provided on the side facing the cover with the locking projection and on the side facing the door closer housing has a U-shaped opening and forms the abutment rib for form-fitting connection with the door closer housing, and wherein the leg surfaces of the hood holder in the longitudinal direction of the door closer housing overlap with this, on the side facing the door closer housing one of the resilient latching tongues, on the side facing the cover hood, each with a clamping spring for producing the clamping connection with the cover hood and one each have a resilient positioning arm protruding from the cover.
  • hood holder - as is also provided according to the invention - is symmetrical with respect to a central plane running along the door closer housing perpendicular to its mounting plane, it can be used optionally on each of the two end faces of the door closer housing.
  • hood holders according to the invention are designed as plastic injection molded parts.
  • a cross-sectionally substantially U-shaped hood holder 1 is shown with a web surface 2 and leg surfaces 3, 4 running perpendicularly thereto.
  • the web surface 2 of the hood holder 1 manufactured as an injection molded part, there is a keyhole-like opening 5 and adjacent window-like recesses 6, 7 provided.
  • a locking tongue 8 protrudes perpendicular to the plane of the drawing in FIG. 1a with a central locking projection in the form of a locking pin 9.
  • the locking tongue 8 with a thin point 10 is at the adjacent area of the web surface 2 molded.
  • the web surface 2 On its rear side, which is shown in particular in FIG. 1d, the web surface 2 has a U-shaped stop rib 11 with a contact surface 12 projecting perpendicularly from the web surface 2.
  • the leg surfaces 3, 4 are provided with retaining springs in the form of mutually directed elastic locking tongues 13, 14 and resilient positioning arms 15, 16.
  • In window-like recesses of the leg surfaces 3, 4 protrude clamping springs 17, 18, which in the starting position project over the leg surfaces 3, 4 as well as the locking tongue 8 with the locking pin 9 over the web surface 2.
  • the free ends of the locking tongues 13, 14 and the positioning arms 15 , 16 are formed with a cylindrical cross section.
  • the optional right / left usability of the hood holder 1 results from its symmetrical design with respect to the central plane running perpendicular to the plane of the drawing in the section line I-I of FIG. 1a.
  • the hood holder 1 is first preassembled when a cover hood 19 is mounted thereon.
  • the cover hood 19 is provided with snap-in receptacles 22, 23 on end faces 20, 21.
  • a cutout 25 open at the edge is left out in a longitudinal surface 24.
  • the hood holder 1 with the positioning arms 15, 16 is first inserted into the interior of the cover hood 19.
  • the hood holder 1 is aligned such that the locking pin 9 engages in the locking receptacle 22 on the end face 20 of the cover 19.
  • the leg surfaces 3, 4 of the hood holder 1 ensure its flat support inside the cover hood 19.
  • a clamping connection between the two components is established with the aid of the clamping springs 17, 18, which in cooperation with the positive connection between the locking pin 9 and the snap-in receptacle 22 fix the hood holder 1 to the cover hood 19 in the preassembly position.
  • the assembly consisting of the cover hood 19 and the hood holder 1 is first attached to the mounting surface of a door closer housing 26 with its end facing away from the hood holder 1.
  • the end of the cover 19 provided with the preassembled hood holder 1 is pivoted at an acute angle against the mounting plane of the door closer housing 26.
  • the covering hood 19 is brought into engagement by sliding in the longitudinal direction via the latching receptacle 23 on its end face 21 with a bearing journal (not recognizable in FIG. 3) on the associated end face of the door closer housing 26.
  • the edge-open cutout 25 encloses the shaft of the door closer system shown, which is indicated in FIG. 3 and emerges from the cover 19 upwards.
  • the U-shaped stop rib 11 engages around a projection provided on the end face of the door closer housing 26 which is visible in FIG. 3 and thereby creates a form-fitting connection between the hood holder 1 and the door closer housing 26.
  • the positioning arms 15, 16 not least ensure that the covering hood 19 is securely supported on the hood holder 1.
  • the positioning arms 15, 16 cause the covering hood 19 and the hood holder 1 to self-center relative to one another. Nevertheless, a functional hood holder can also be implemented without the positioning arms 15, 16.
  • the cover 19 which is held in the installed position, can be pulled off from the door closer housing 26 together with the hood holder 1 which is positively attached thereto in the direction of arrow B according to FIG. 4.
