Description

Door closer case and door closer with such a door closer housing

The invention relates to a door closer housing, which extends with its longitudinal direction in the direction of the line of action of the force in the interior of the door closer housing closer actuator, preferably a closing spring, and having a housing wall, which provided at least one longitudinal end of the door closer housing with a housing cover closed by a housing cover is, wherein the housing cover extends in the transverse direction of the door closer housing and is supported in the longitudinal direction of the door closer housing to the housing wall.

The invention further relates to a door closer with a door closer housing of the above type.

Generic prior art is known from DE 39 08 340 AI. This document relates to a hydraulic door closer with a door closer housing in the interior of which a closing piston in the longitudinal direction of the door closer housing is displaceable. The closing piston has a piston toothing, with which a toothed pinion seated on a closing action meshes. When opening the door provided with the door closer the closer shaft is set in a rotational movement, which is implemented via the pinion and the piston teeth in an opening movement of the Schiießerkolbens in the longitudinal direction of the door closer housing. The opening movement executes the closing piston under compression of a closing spring, which is supported on the one hand on the Schließerkoiben and on the other hand on an end wall of the door closer housing. If the door is released after opening, the previously compressed closing spring relaxes and drives the closing piston with a closing movement opposing the opening movement. The closing movement of the closing piston is damped by hydraulic fluid is displaced from a housing chamber of the Türschiießergehäuses, which is formed between the vorvorenden in the direction of the closing longitudinal end of the closing piston and the door closer housing in the said direction limiting threaded plug. The threaded plug is screwed with an external thread in an internal thread of a closed by the threaded plug housing opening of the Türschiießergehäuses. In order to withstand the pressure load occurring during operation of the door closer, the threaded connection between the threaded plug and the housing wall of the Türschiießergehäuses must be sufficiently resilient. For a load-bearing internal thread can be cut into the housing wall, it requires a relatively large wall thickness of the housing wall. Accordingly bulky is the previously known door closer housing.

The object of the present invention is to provide a door closer housing which, with sufficient performance of the normally-located closer actuator, builds a door closer with such a slim-fitting door closer housing. This object is achieved according to the invention by the door closer housing according to claim 1 and by the door closer according to claim 11.

In the case of the invention, the housing cover of the door closer housing is mounted by means of a pin connection to the housing wall of the door closer housing. The pin connection comprises at least one extending in the transverse direction of the Türschiießergehäuses connecting pin which is supported in the longitudinal direction of the door closer housing on the housing wall and which in turn supports the housing cover in the longitudinal direction of the Türschiießergehäuses. The term "pin connection" is to be understood in a broad sense: it describes connections which are produced with the aid of "pins" in the narrower technical sense, ie with smooth-walled connection elements without a head, but also connections that differ from other elongated connection elements for example, use threaded and unthreaded studs with or without head or rivets. Accordingly, the term "connecting pin" in the context of the invention to understand.

The cross-section of a door closer housing is distributed essentially on the cross section of the housing interior and the cross section of the housing wall, The cross-sectional size of the interior of the Türschiießergehäuses is determined by the dimensions of the closer actuator to be arranged there, in particular by the diameter of a housed inside the housing closer spring. The dimensions of the closing drive or the diameter of the closing spring in turn depend on the closing force to be applied and are hardly variable at a given closing force. The construction according to the invention of the connection of the housing wall and the housing cover of the door boot housing permits a minimization of the proportion of the total cross section of the door housing attributable to the housing wall of the door boot housing. Closer housing. Because provided in the case of the invention pin connection of the housing wall and the housing cover has a high load capacity in the longitudinal direction of the door closer housing even with a small wall thickness of the housing wall. Even with high closing forces, door locker housings according to the invention consequently have a small overall cross-section.

The correspondingly slim design of door closers according to the invention is advantageous in the case of overlying, that is to say visibly mounted door closers housings and, to a particular degree, in concealed door closer housings. In the latter case, such as during installation in the interior of a door leaf, is for the Türschiießergehäuse usually only a small installation space available. Nevertheless, the door closer must apply a sufficient closing force. Inventive Türschiießergehäuse be due to their lean on the available power of the door closer construction both boundary conditions.

In addition, the pin connection according to the invention of the housing wall and the housing cover of a door closer housing is also recommended from a production engineering point of view,

On the one hand, the connecting elements of the pin connection according to the invention are structurally simple. On the other hand, the pin connection according to the invention can be produced in a simple manner. Thus, for example, no threads for producing the connection between the housing cover and housing wall must be made on the contact surface of the housing cover and the housing wall. And the assembly of a door closer is simplified when use is made of a Türschiießergehäuse invention. Usually, the closer drive is introduced into the already closed at one longitudinal end door closer housing during assembly of a door closer, before the remaining housing opening is closed with the housing cover. The closing spring of the closer drive inserted into the interior of the door closer housing is initially still relaxed and the closer drive consequently has an excess in the longitudinal direction of the door closer housing relative to the door closer housing. To apply the still missing housing cover this is placed in the longitudinal direction of the door closer housing on the projecting from the door closer housing end of the closer drive and then moved against the action of the increasingly compressed closing spring in the longitudinal direction of the door closer housing to this. If the housing cover has reached its installation position in the longitudinal direction of the door closer housing, then it is merely to be pinned to the housing wall. Accordingly, the Gehäusedeckei in the case of the invention for attachment to the housing wall only to move translationally. In contrast, the preparation of a threaded connection between the housing cover and the housing wall of a door closer housing requires not only a translational movement of the housing cover in the longitudinal direction of the door closer housing but also a rotational movement of the housing cover about the axis of its translational movement. In this case, the rotational movement of the housing cover takes place under increasing loading of the housing cover by the more and more compressed closing spring and relative to the directly from the Gehäusedeckei acted upon normally-open actuator. Due to the rotational movement of the housing cover, which is performed under load, relative to the component of the closer drive which is directly adjacent to it, damage can occur at the contact surface of the housing cover and drive component. If material dissolves material on the housing cover or on the drive component impinged thereon by the material, for example in the form of chips, there is a risk that the radio tion capability of the door closer during later operation is affected by the detached material. The pin connection according to the invention of housing cover and housing wall of a Türschiießergehäuses does not involve such risks.

Finally, provided on the door closer housings according to the invention pin connection between the housing wall and the housing cover is also advantageous from an aesthetic point of view. After the housing cover does not have to perform any rotational movement during assembly, otherwise required engagement openings for a mounting tool for generating a rotational assembly movement of the housing cover unnecessary. The housing cover inventive door closer housing can thus have a smooth and thus aesthetically pleasing surface.

Particular embodiments of the invention according to independent claims 1 and 11 emerge from the dependent claims 2 to 10.

In the case of Erfindungsbauart according to claim 2, the housing wall of the door closer housing has cross-sectional areas with different wall thicknesses. The one or more cross-sectional areas with increased wall thickness are used because of their pronounced load-bearing capacity for supporting the one or more connecting pins of the pin connection according to the invention. An enlarged wall thickness, for example, those parts of the housing wall of the invention Türschiießergehäuses have, in which the closer shaft of the door closer is mounted.

In principle, there is the possibility that the one or more connecting pins of the pin connection according to the invention are supported resting on the housing wall of the Türschiießergehäuses. In a preferred embodiment of the invention are for the support of the or the connecting pins provided on the housing wall pin receiving openings extending in the transverse direction of the door closer housing (claim 3). For the preparation of such pin receiving openings offer different possibilities. In particular conceivable are pin receiving openings in the form of receiving bores. Preferred dimensions of the connecting pins protrude beyond the housing cover to be fixed with its two longitudinal ends. With the supernatants, the connecting pins are mounted on the housing wall of the door closer housing. With a corresponding dimensioning of the cross-section of the pin receiving openings on the one hand and the diameter of the connecting pieces on the other hand, separate measures for the axial fixing of the connecting forces in the installed position are unnecessary.

The support of the housing cover on the one or more connecting pins of the pin connection can be realized according to the invention in different ways. According to claim 4, it is provided in a preferred embodiment of the invention that the one or more connecting pins rest on the outside of the housing cover. To support the housing cover in the longitudinal direction of the door closer housing is required in this case no special design measures on the housing cover. Additionally or alternatively, the housing cover of the invention type according to claim 5, at least one extending in the transverse direction of the door closer housing pin receiving opening for the one or more connecting pins of the pin connection.

Particularly simple is the production of the pin connection according to the invention, if - provided as claimed in claim 6 - the housing cover in the longitudinal direction of the door closer housing overlaps with the housing wall and the at least one connecting pin of the pin connection in the region of the overlap in a extending in the transverse direction of the door closer housing pin receiving opening on the Housing wall and / or engages in a extending in the transverse direction of the door closer housing pin receiving opening on the housing cover. The pin connection according to the invention can be produced in this case directly between the housing wall and the housing cover.

In the case of a further preferred type of invention (claim 7), it is provided that the housing cover which overlaps the housing wall in the longitudinal direction of the door closer housing has a circular peripheral contour and is enclosed in the circumferential direction by the housing wall. In this case, the housing cover is provided in the interest of ease of installation with a radially outwardly open circumferential groove which serves as a pin receiving opening for the one or more connecting pins of the pin connection of housing wall and housing cover. With the circumferential groove is on the housing cover a pin receiving opening available, which is accessible at each of the housing cover in its circumferential direction relative to the housing wall rotational position for the one or more connecting pins of the pin connection.

Also to simplify the mounting of the housing cover on the housing wall, the door closer housing according to the invention has a positioning on the housing wall and / or on the housing cover, by means of which the housing wall and the housing cover relative to each other in the longitudinal direction of the door closer housing and / or in the circumferential direction of the housing cover can be positioned with a mutual desired position.

In a preferred embodiment of the invention, a depth stop is provided according to claim 9 as a positioning device on the housing wall and / or on the housing cover, by means of which the housing wall and the housing cover are positioned relative to each other in the longitudinal direction of the door closer housing with a mutual desired position. additional or alternatively can be provided as a positioning on the housing wall and / or on the housing cover a Umfangsanschiag which marks the mutual desired position of the housing wall and housing cover in the circumferential direction of the Gehäusedeckeis. Their mutual Soillage take the housing wall and the housing cover of the door closer housing according to the invention in particular when the one or more connecting pins of the pin connection can be introduced and / or when the housing cover tightly closes the associated housing opening of the door closer housing.

For the one or more connecting pins of the pin connection according to the invention different designs come into question. Particularly conceivable are smooth-walled connecting pins and / or connecting pins in the form of threaded pins and / or connecting pins in the form of solid pins and / or in the form of grooved pins and / or in the form of dowel pins (claim 10).

The invention will be explained in more detail below with reference to exemplary schematic illustrations. Show it :

Fig ur 9 is an end view of a structurally modified compared to Figure 7 door closer housing.

According to FIGS. 1 and 2, a door closer 1 has a door closer housing 2 with a housing wall 3 and two identical housing covers 4. The housing cover 4 have a circular peripheral contour and close housing openings 5, which are provided at the two longitudinal ends of the housing wall 3. The door closer 1 is provided for overlying mounting on the fixed frame or on the wing of the relevant door.

In the interior of the door closer housing 2, a non-recognizable in the figures hydraulic closer drive of conventional design with a closer spring and a closer piston is arranged. The closing piston has a piston toothing, on which it meshes with a toothed pinion, which in turn is seated on a closer shaft of the door closer 1. Shaft ends 6, 7 of the closer shaft can be seen inter alia in FIG. At one of the shaft ends 6, 7 of the overhead mounted Türschiießer 1 is connected via a linkage with the fixed frame or the wing of the relevant door. A geometric shaft axis 8 of the closer shaft is indicated by dash-dotted lines in the figures. The line of action 9 defines the longitudinal direction of the door closer housing 2. In the direction of the line of action 9 of the closing spring 4 pressure forces are exerted upon operation of the door closer 1 on the inside of the housing cover, in ur ur 2 are indicated by arrows verschaulicht. To support the pressurized Gehäusedeckei 4 on the housing wall 3 in the direction of the line 9 or in the longitudinal direction of the door closer housing 2 two identical pin connections 10 are provided at the two longitudinal ends of the door closer housing 2, the structural design is shown in detail in Figures 2, 3a and 3b ,

Accordingly, each of the pin connections 10 comprises two connection pins 11, 12, which are designed as dowel pins in the illustrated example. The connecting pins 11, 12 pass through the housing wall 3 pin receiving openings 13, 14 which extend in the transverse direction of the geometric shaft axis 8 a. The Stiftaufna hmeöffnungen 13, 14 are in cross-sectional areas 15, 16 of the housing wall 3, which have an increased wall thickness compared to the remaining Querschntttsbereichen the housing wall 3.

On the housing covers 4 of the Türschlteßergehäuses 2, the connecting pins 11, 12 engage in a extending in the transverse direction of the door closer housing pin receiving opening 17 of the respective pin connection 10 a. The pin receiving openings 17 are formed by a radially outwardly open circumferential groove 17 of each housing cover 4. In installation ulage on the housing wall 3 are pinned with this housing cover 4 on a contact shoulder 18 a n, which is formed at the transition between each of the housing openings 5 and the interior of the door closer housing 2. Adjacent to the abutment shoulder 18, a sealing groove 19 with an O-ring seal 20 is provided on each of the housing covers 4. The O-ring seals 20 seal the interior of the door closer housing 2 to a outside.

When Zusammenba u of the door closer 1, one of the housing openings 5 is first closed with a housing cover 4. To this end the relevant housing cover 4 is inserted in the longitudinal direction of the door closer housing 2 in the associated housing opening 5 until it runs onto the contact shoulder 18 surrounding this housing opening 5. The abutment shoulder 18 serves as a positioning device, in detail as a depth stop for the housing cover 4 and marks that position of the housing cover 4, in which this takes its Soiliage in the longitudinal direction of the door closer housing 2 with respect to the housing wall 3. If the housing cover 4 is supported on the contact shoulder 18, then the pin receiving openings 13, 14 of the housing wall 3 are aligned with the circumferential groove or pin receiving opening 17 of the housing cover 4 and the connecting pins 11, 12 can be pushed into the pin receiving openings 13, 14, 17 under pressure be introduced on the housing wall 3 and the housing cover 4. Since the connecting pins 11, 12 are dowel pins which, in the initial state, have a diameter oversize relative to the pin receiving openings 13, 14 of the housing wall 3, no separate measures are required for their axial fixing in the installed position.

According to FIG. 3b, the connecting pins 11, 12 engaging their end division are aligned with the housing wall 3 at one longitudinal end. The connecting pins 11, 12 protrude beyond the housing wall 3 with their opposite longitudinal end. The supernatant of the connecting pins 11, 12 is used to support the door closer 1 on a mounting plate, not shown, in turn, with the fixed frame or the flights! the door in question is connected.

After pinning one of the housing cover 4 with the housing wall 3 is inserted through the still unlocked housing opening 5 of the closer actuator with closer spring and closer piston in the interior of the door closer housing 2. Since the closing spring is relaxed, the closer drive is at the still unclosed housing opening 5 in Longitudinal direction of the door closer housing 2 on the housing wall 3 before. On the projecting end of the closer actuator provided as a closure for the remaining housing opening 5 housing cover 4 is placed. Subsequently, the housing cover 4 is pressurized in the longitudinal direction of the door closer housing 2 along the Wirkungsiinie

9 moves in the direction of the housing wall 3 and inserted into the housing opening 5 until it abuts against the abutment shoulder 18. Now, the second Gehäusedeckei 4 takes on the housing wall 3 its desired position and the second pin connection 10 can be made in the manner described above by means of the connecting pins 11, 12.

In the installation position, the housing cover 4 overlap in the longitudinal direction of the door closer housing 2 with the housing wall 3, from which they are enclosed in the circumferential direction. At its located in the longitudinal direction of the door closer housing, smooth-surfaced outside the mounted housing cover 4 with the end faces of the housing wall 3, on which the Gehäusedeckei 4 through the connecting pins 11, 12 of the pin connections

10 are supported under the action of acting on them closer actuator.

A door closer housing 32 shown in FIGS. 4a, 4b and a door closer housing 62 shown in FIGS. 5a, 5b differ from the door closer housing 2 according to FIGS. 1 through 5b only in terms of the design of housing covers 34 (FIGS. 4a, 4b) and of housing covers 64 (FIGS. 5a, 5b) and resulting from the execution of pin connections 40 and pin connections 70. Incidentally, the arrangements according to FIGS. 4a to 5b correspond to the arrangement according to FIGS. 1 to 3b,

Deviating from the housing covers 4, neither the housing cover 34 nor the housing cover 64 have a pin groove formed as a circumferential groove. opening on. The housing covers 34 instead have a stepped outside diameter with a smaller diameter axial portion 41 and a larger diameter axial portion 42. The transition between the axial portion 41 and the axial portion 42 of the housing cover 34 is designed as a groove 43 whose radius corresponds to the radius of the connecting pins 11, 12. In the installed position, the connecting pins 11, 12 support the relevant housing cover 34 on the housing wall 3 from the outside on the latter. In this case, the connecting pins 11, 12 snugly fit into the groove 43 provided on the relevant housing cover 34.

On the housing covers 64 instead of a circumferential groove two parallel extending and designed as a straight-bore bores pin receiving openings 77, 78 are provided. At the pin receiving openings 77, 78 are located in the installation position housing cover! 64 penetrated by the connecting pins 11, 12 of the respective pin connection 70. When mounting the housing cover 64, care must be taken that they are transferred relative to the housing wall 3 not only in the longitudinal direction of the door closer housing 2 but also in the circumferential direction into a desired position. Only under this condition does it ensure that the pin receiving openings 77, 78 on a housing cover 64 are aligned with the associated pin receiving openings 13, 14 of the housing wall 3.

Figures 6 to 9 show a door closer 101, which is intended for concealed installation. In installation position, the door closer 101 is sunk in a door leaf of the respective door. On the upper side of the door leaf, a shaft end 106 serves to connect a linkage connecting the door closer 101 to the fixed frame of the door to the closer shaft of the closure accommodated in the interior of a door closer housing 102. ßerantriebes. An action line 109 of the closing spring of the closer drive runs in the longitudinal direction of the door closer housing 102.

Deviating from the conditions according to FIGS. 1 to 5b, pin connections 110 (FIGS. 7 to 8b) and 140 (FIG. 9) have connecting pins 111, 112 which extend parallel to a geometric shaft axis 108 of the closer of the door closer 101.

Incidentally, the door closer housing 102 shown in detail in FIGS. 7 to 8b corresponds to the door closer housing 62 according to FIGS. 5a, 5b. The pin connections 110 ensure that housing openings 105 closing the housing cover 104 are effectively supported in the longitudinal direction of the door closer housing 102 on a housing wall 103. The connecting pins 111, 112 pass through pin receiving openings 113, 114 on the housing wall 103 and pin receiving openings 117, 118 on the housing covers 104. The pin receiving openings 113, 114 are arranged on the housing wall 103 in cross-sectional areas 115, 116 with a relatively large wall thickness. An abutment shoulder 128 serves to assemble the door closer 101 as a positioning device or as a depth stop for the housing cover 104.

A door closer housing 132, as shown in FIG. 9, coincides with the door closer housing 32 according to FIGS. 4a, 4b, apart from the orientation of the connection pins 111, 112 of the pin connections 140. The connecting pins 111, 112 of the pin connections 140 also support the housing cover 134 on the housing wall 103 in the longitudinal direction of the door slider housing 132, by resting on the outside of the housing cover 134.

All door closer housings 2, 32, 62, 102, 132 shown in FIGS. 1 to 9 have a small width and thus a slim design. The parallel to the geometric shaft axis 8, 108 extending housing side walls have a thickness of only a few millimeters. Nevertheless, the pin links 10, 40, 70, 110, 140 in the longitudinal direction of the door closer housing 2, 32, 62, 102, 132 such that they on the inside of the housing cover 4, 34, 64, 104, 134 of withstand the pressure exerted on the respective NO contact drive without problems.
