Description

Door closer combination

The present invention relates to a door closer assembly having a door closer and a mounting plate for mounting the door closer to a support member such as a door leaf, a door sill, a wall, a ceiling or the like. The door closer can be fixed to the mounting plate, the mounting plate has a retaining section and the door closer has a relative retaining section, which cooperates with the retaining section, and is defined by an orthogonal insertion and lateral movement or rotation in a fixed direction on the mounting plate. Upon installation movement, the retaining segment and the opposing retaining segment are at least partially clamped into engagement with each other.

The door closer can be implemented as a mechanically operated door closer or a power operated door drive. A mechanically operated door closer includes an energy storage mechanism, such as a spring-based storage mechanism that stores a potential energy for a manually implemented, for example, door leaf opening motion. This potential energy is sufficient to perform subsequent closing movements such as door leaves. If the door closer is a power operated door drive, the door closer can perform both types of movement, such as door leaf opening, and closing motion.

The door closer can be directly mounted on a support member, such as a door frame, a door leaf, a door sill, a wall, a ceiling or the like, by using at least two screws, the screw can pass through the door closer, and then the snail Into the support. In addition, a door closer designed to open and/or close a connected door, window or the like is typically mounted to a support member by a mounting plate, such as a door frame, a door leaf, a door sill, a wall, a ceiling or On the analog. Thus, the mounting plate is, for example, fixed to the support member in advance, such as a door frame, a door leaf, a door sill, a wall, a ceiling or the like. Secondly, the attached door closer is fixed on the mounting plate. That is, the mounting plate holds the door closer on the support member. If a mounting plate is used, the mounting plate can be first mounted on the support by, for example, using a plurality of screws, in particular wood screws or expansion screws. After the mounting plate is mounted on the support, the door closer is mounted on the mounting plate. The conventional practice is to use screws The door closer is fixed to the mounting plate, and the screw is guided through the door closer and screwed vertically into the mounting plate. The disadvantage of this fixing method is that after the door closer is mounted on the mounting plate, the screw connection can be seen from above the door closer. The screw is located near the reach of the hand. Therefore, the screw head and the screw hole are susceptible to contamination. In addition, people may be injured by the protruding screws. Due to this disadvantage, a cover can be used to cover the screw head or the screw hole. However, such cover is easily lost or negatively affects the grip of the door closer combination handle.

A mounting plate for fixing a door is known from DE 20 2007 005 265 U1. The door closer can be screwed to the mounting plate. The mounting plate contains a screw hole that accepts the screw of the door closer. Thus, the door closer includes a housing having a plurality of through holes that are aligned with the screw holes of the mounting plate for receiving the set screws. The screw is perpendicular to the mounting plate and extends to the top surface of the door closer, which can also be viewed from the side. Screws and through holes, or any possible cover, can be easily accessed by personnel who operate the door closer combination. Coverage may be lost. Lack of cover, screw heads and through holes are susceptible to contamination.

The object of the present invention is to provide a door closer assembly, comprising a door closer and a mounting plate, which can quickly and easily and properly install and secure the door closer on the mounting plate, thereby providing a quick, easy and proper door closer. The combination is mounted and secured on a support member such as a door frame, a door leaf, a door sill, a wall, a ceiling or the like. In particular, the locking of the door closer on the mounting plate should be carried out in a non-contaminating and non-interfering position.

The foregoing objects are achieved by a combination of door closers including all of the features of the first claim independent of the scope of the patent application. The advantages, features, details, aspects and effects of the present invention are disclosed in the accompanying claims, the description and the drawings.

The foregoing object is achieved by a combination of a door closer having a door closer and a mounting plate for mounting the door closer to a support member, such as a door frame, a door leaf, a door sill, a wall, and a door. On the ceiling or the like, and the door closer can be fixed On the mounting plate, the mounting plate has a retaining section, and the door closer has a relative retaining section that cooperates with the retaining section to define a mounting motion via an orthogonal insertion and lateral movement or rotation in a fixed direction on the mounting plate. The generating retaining section and the opposing retaining section are at least partially clamped to each other. The door closer combination is further characterized in that the door closer comprises a casing having at least one hole, each of the at least one hole receiving a screw, and each screw is used for fixing the door closer in the reverse fixing direction at the end of the installation movement. a plate, and the longitudinal axis of the at least one hole is perpendicular or substantially perpendicular to a normal vector of the mounting plate. The substantially vertical dimension refers to the longitudinal axis of the at least one aperture of the door closer, and thus the longitudinal axis of the screw in the at least one aperture, the angle of the normal vector to the mounting plate being between 80° and 100°. When the mounting plate is fixed to a support member, the normal vector of the mounting plate is perpendicular to the plane of the support member. Generally, the mounting plate is rectangular or substantially rectangular. The retaining section of the mounting plate is preferably on the side of the mounting plate. The retaining section of the mounting plate can have a wing-like structure. According to a preferred embodiment of the present invention, the door closer assembly has a retaining section of the mounting plate disposed on opposite sides of the mounting plate. The mounting plate has in particular a planar or substantially planar extension. Thus, the mounting plate can be fixed in parallel to a support member such as a door frame, a door leaf, a door sill, a wall, a ceiling or the like. The door closer combination door closer can be fixed to the mounting plate via an orthogonal insertion and subsequent lateral movement, a so-called door closer slide on. Thus, the retaining section of the fixed mounting plate engages with the opposite retaining section of the door closer. At the end of the lateral movement or rotation, the retaining segments of the mounting plate and the opposing retaining segments of the door closer are at least partially clamped into engagement with each other. The retaining section at least ensures that the door closer is fixed vertically to the mounting plate. In order to ensure that the door closer does not move laterally parallel to the mounting plate, the door closer has a housing having at least one hole, each of the holes being designed to receive a screw, and each of the screws is for reversing the direction at the end of the mounting movement. A door closer is fixed and the longitudinal axis of the at least one hole is perpendicular or substantially perpendicular to a normal vector of the mounting plate. The door closer is screwed into the mounting plate on the mounting plate by at least one screw, either vertically or substantially perpendicular to the mounting plate normal vector. This additional fixing ensures that the door closer is properly secured to the mounting plate. By The special arrangement of at least one hole in the door closer housing, and thus the arrangement of at least one screw of the mounting plate, results in a quick, easy and proper installation and warranty of the door closer on the support member, and thus a quick and easy The proper door closer is assembled and secured on a support member such as a door frame, a door leaf, a door sill, a wall, a ceiling or the like. In particular, the locking of the door closer on the mounting plate can be carried out in a non-contaminating and non-interfering position. The non-interfering position means that when the door closer is additionally fixed to the mounting plate by at least one screw, the screw is indeed located in the operation of the door closer combination, in particular, the operation of a door closer combination handle, outside the range of the human hand. The at least one hole is perpendicular or substantially perpendicular to the normal vector of the mounting plate, ensuring that the screw is easily accessible and isolating the screw from a regulating valve screw, which is generally disposed on the front side of the door closer housing.

According to a preferred embodiment of the present invention, one of the door closer combinations is provided on one side of the door closer housing, particularly near the bottom of the housing, such that after the door closer is placed and laterally moved or rotated on the mounting plate The hole extends downward. After the door closer is installed and secured on the mounting plate, it is not possible to touch the position of the screw that secures the door closer to the mounting plate unless it is known in advance. This design prevents the screws from being mis-rotated. The user who operates the door closer combination handle cannot see the holes and screws. The door closer is held by the retaining section and the opposite retaining section, the at least one hole of the screwing door closer and the at least one screw entering the mounting plate, and is firmly secured on the mounting plate.

A preferred combination of door closers is that the at least one aperture of the door closer is parallel to the open bottom of the door closer. The door closer is preferably open at the bottom side so that the door closer can be placed into the mounting plate. After the door closer is placed in the mounting plate and moved or rotated sideways, the mounting plate is shielded by the bottom of the door closer. Thus, the at least one screw can be passed through the at least one hole in the door closer housing and screwed into the side of the mounting plate.

According to a preferred embodiment of the present invention, after the installation movement is finished, the screws of the door closer combination can fix the door closer to the mounting plate in a force fitting manner. on. The at least one screw can be screwed directly into the mounting plate. Preferably, the mounting plate of the door closer combination includes at least one hole for receiving at least one screw. The at least one screw can be screwed through the at least one hole of the door closer housing into the corresponding hole of the mounting plate to fix the two to each other. That is, after the door closer is placed on the mounting plate and moved or rotated sideways, and the holding section of the mounting plate and the corresponding holding section of the door closer enter the engaged state, the at least one hole of the door closer housing and The corresponding at least one hole of the mounting plate is aligned with each other so that the screws can be screwed into the two holes respectively.

According to another preferred embodiment of the present invention, the at least one hole of the mounting plate of the door closer assembly is located at at least one protrusion of the mounting plate, and the protrusion is at an angle of 90° or substantially 90° to the longitudinal axis of the mounting plate. . A substantially 90° angle means that the angle of the at least one protrusion to the longitudinal axis of the mounting plate may be between 80° and 100°, or between the angles of -10° and 10° to the normal vector of the mounting plate. The inclination of the at least one protrusion corresponds to the direction of the at least one hole of the door closer housing.

The at least one protrusion can be fixed to the mounting plate. Preferably, the at least one projection of the door closer combination is integral with the mounting plate, in particular integral.

Further preferably, the door closer assembly is characterized in that the at least one hole of the door closer housing and/or the at least one hole in the protrusion of the mounting plate is threaded. It means that only one aligned hole can be threaded. The thread may be part of the at least one hole of the door closer housing or at least one hole provided in the mounting plate. If there is a very secure connection between the mounting plate and the door closer, the two holes, that is, the at least one hole of the mounting plate and the at least one hole of the door closer housing, may each have a thread.

According to another preferred embodiment of the present invention, the at least one screw of the aforementioned door closer assembly is a countersunk screw, and the at least one hole of the door closer housing is designed such that it can completely receive the head of a countersunk screw. This ensures that the at least one screw that additionally secures the door closer to the mounting plate does not protrude from the door closer housing. Preferably, the countersunk head is flush with the outside of the housing. Therefore, damage and pollution can be avoided.

Further, preferably, a latching member is disposed in the middle portion of the mounting plate on the mounting plate, and a latching member is disposed on the door closer, and the latching member engages with the opposing latching member at the end of the mounting movement. The mounting plate can be screwed to a support member and the screw is guided through the through hole in the mounting plate. The latch component is disposed in a middle portion of the mounting board. The latch element can be spring-elastically designed as a notch. Thus, the latch component can comprise a U-shaped profile. Since the latching element is designed in a spring-elastic manner, the latching element can be resiliently pushed back when the door closer is installed on the mounting plate.

The door closer comprises a relatively latching element, a so-called stop, in particular in the form of a projection designed to engage the latching element of the mounting plate at the end of the mounting movement. The latch components are respectively protruded from the mounting plate and protrude from the plane of the mounting plate, so that when the door closer slides in the fixed direction on the mounting plate, the spring-elastic latching member can be opposite to the latching member of the door closer in the direction of the mounting plate. Push back, the relative latching element is preferably in the shape of a protrusion. At the end of the mounting movement, the latching element engages the opposing latching element and engages behind the opposing latching element. That is, the latching element of the mounting plate is designed such that it can be moved in the direction of the mounting plate in a spring-elastic manner. It can be pushed back in the installation procedure of the door closer on the mounting plate. At the end of the mounting movement, the latching element can spring back to its original position after the opposing latching element and thus engage behind the opposing latching element. Due to the clamping engagement of the retaining segments of the mounting plate with the opposing retaining segments of the corresponding door closers and the engagement of the latching elements with the opposing latching members, the door closer can be secured to the mounting plate in all directions. The door closer can be absolutely fixed on the mounting plate by at least one screw. To release the door closer from the mounting plate, the at least one screw must be removed and the latch card member must be pushed back so that the opposite latching member of the door closer and thus the door closer can be released from the mounting plate.

In accordance with another preferred embodiment of the present invention, the latching member of the door closer assembly and the at least one projection extend from the mounting plate in the same direction. The at least one protrusion for ensuring that the at least one screw is installed is introduced into the interior of the door closer, so that at least one screw can be screwed through the door The at least one aperture of the housing enters the mounting plate in a manner perpendicular or substantially perpendicular to the normal vector of the mounting plate, particularly in at least one of the projections of one of the mounting plates.

Furthermore, it is preferred that the door closer combination is characterized in that the door closer housing, in particular the bottom of the housing, comprises a dimple. The recess is designed such that it provides a number of resistances against the overtravel during installation, i.e., resists the overtravel of the lateral movement or rotation of the door closer on the mounting plate. In particular, the recess may be provided on the front side of the door closer housing, towards the support when the door closer is mounted to the mounting plate. The recess can be designed as a recess to compress the latch component when the door closer is removed from the mounting plate. Once the relative retaining section of the door closer is disengaged from the retaining section of the mounting plate, the door closer can be removed by the mounting plate without any tools. To release the latch component from the opposite latch component, a large force is applied in the opposite direction of the fixed term. That is, the notches release the latch component from the opposing latch component.

To remove the door closer, the user only needs to remove the at least one screw, which is oriented for easy access. A certain force is then applied to reverse the sliding direction so that the housing is released from the retaining section of the mounting plate.

Fig. 1 shows a mounting plate 11 of one of the door closer combinations of the present invention in a perspective view. The mounting plate 11 includes a retaining section 12 for closing the door closer 10 in combination with a door closer, such as shown in Figure 2, in engagement with the retaining section 13. The mounting plate 11 further includes two projections 17 located on opposite side walls of the mounting plate 11. Each projection 17 is at an angle of 90 to the longitudinal axis 19 of the mounting plate 11. That is, the extension of the protrusion 17 is parallel or substantially parallel to the normal vector 20 of the mounting board 11. The projections 17 may also have an angle of the longitudinal axis of the mounting plate between 80° and 100°. Each of the projections 17 includes a hole 18 designed to receive a screw that secures the door closer 10 to the mounting plate 11. The protrusion 17 can be fixed to the mounting board 11. Preferably, the protrusion 17 of the door closer assembly 1 is integral with the mounting plate 11, in particular integral, as shown in FIG.

The mounting plate 11 has a hole 21 for fixing the mounting plate 11 on a supporting member, such as Door frame, a leaf, a door, a wall, a ceiling or the like.

The door closer 10 can be fixed to the mounting plate 11. To this end, the mounting plate 11 comprises a retaining section 12 and the door closer 10 comprises an opposing retaining section 13, see Fig. 2, the opposing retaining section being fitted with a retaining section. A mounting movement is defined by a lateral movement or rotation of the mounting plate 11 on a mounting plate 11 in a fixed direction 14 such that the retaining section 12 and the opposing retaining section 13 of the door closer 10 are at least partially clamped to each other. Engage.

A latching member 25 is disposed on the mounting plate 11 at an intermediate portion of the mounting plate 11, and the latching member 25 is designed to be engaged with the latching member 30 of the door closer 10 when the mounting movement of the door closer 10 on the mounting plate 11 is completed. Hehe. The mounting plate 11 can be screwed, and the screw is fixed to a support member through a hole 21 in the mounting plate 11. The latching element 25 can be designed as a notch in a spring-elastic manner. Thus the latch component 25 can have a U-shaped profile. Since the latching card member is designed to be spring-elastic, the latching member 25 can be resiliently pushed back when the door closer 10 is mounted on the mounting plate 11.

Figure 2 is a perspective view showing a door closer 10 of a door closer assembly 1 designed in accordance with the design principles of the present invention. The door closer 10 includes a relatively latching member 30, commonly known as a stopper, particularly in the form of a projection that is designed to engage the latching member 25 of the mounting plate 11 at the end of the mounting motion. The latching members 25 of the mounting plate 11 are respectively protruded from the mounting plate 11 and protruded by the mounting plate 11 so that when the door closer 10 slides in the fixing direction 14 on the mounting plate 11, the spring-elastic latching member 25 can be mounted on the mounting plate The direction of 11 is pushed back by the latching member 30 of the door closer 10, which is preferably shaped as a projection. At the end of the mounting movement, the latching element 25 engages with the opposing latching element 30 and can engage the latching element 30. That is, as shown in FIG. 1, the latching member 25 of the mounting plate 11 is designed to be spring-elastically movable in the direction of the mounting plate 11.

The opposite retaining segments 13 of the door closer 10 are clamped into engagement with the retaining segments 12 of a corresponding mounting plate 11. Since the retaining section 12 of the mounting plate 1 is in clamping engagement with the opposite retaining section 13 of the door closer, and the latching element 25 of the mounting plate 11 and the opposite latch of the door closer 10 The element 13 is engaged and the door closer 10 can be fixed to the mounting plate 11 in all directions. The absolute closure of the door closer 10 on the mounting plate 11 can be achieved by means of a screw 40 which can be screwed into the hole 16 of the housing 15 of the door closer 10 and into the aligned opening 18 of the projection 17 of the mounting plate 11. To release the door closer 10 from the mounting plate 11, the screw 40 (only one screw shown) must be removed, the latching element 25 of the mounting plate 11 must be pushed back, and the opposite latching element 30 of the door closer 10 is mounted. The plate 11 is released, so that the door closer 10 is released.

The latch member 25 and the projection 17 of the mounting plate 17 extend in the same direction by the mounting plate 11. This ensures that the projection 17 of the receiving screw 40 extends into the interior of the door closer 10 so that the screw 40 can be threaded through the hole 16 of the housing 15 of the door closer 10 into the mounting plate 11 in a manner perpendicular or substantially perpendicular to the mounting plate 11 The normal vector 20, in particular, the holes 18 that enter the projections 17 of the mounting plate 11.

A door closer combination 1 is shown in FIG. The door closer assembly 1 includes a door closer 10 and a mounting plate 11 for mounting the door closer 10 on a support member such as a door leaf, a door sill, a wall, a ceiling or the like. . The door closer 10 is fixed to the mounting plate 11. The mounting plate 11 thus has a retaining section 12, while the door closer 10 has an opposing retaining section 13 that cooperates with the retaining section 12. The door closer 10 is mounted on the mounting plate 11 via an orthogonal insertion and lateral movement on the mounting plate 10 in one of the fixed directions 14. The retaining section 12 and the opposing retaining section 13 are at least partially clamped into engagement with one another. The door closer 10 includes a housing 15 having a bore 16 that receives a screw and a screw for securing the door closer 10 in a reverse fixed direction 14 to the mounting plate 11 at the end of the mounting movement. The longitudinal axis of the aperture 16 is perpendicular or substantially perpendicular to the normal vector 20 of the mounting plate 11.

To remove the door closer 10 from the mounting plate 11, the user only has to remove the screws, as shown in Figure 2, the direction of the screws makes it easy to contact. After a certain force is applied in the reverse direction of the sliding direction 14, the housing 15 is released by the retaining section 12 of the mounting plate 11.

This door closer assembly 1 provides a simple installation of the door closer 10 on the mounting plate 11 and a simple mounting on a support member, such as, for example, a door leaf, a door sill, a wall, a ceiling or the like. In particular, the door closer assembly 1 provides an easy, quick and proper installation and insurance of the door closer 10 on the mounting plate 11 of the door closer assembly 1.

There are one or more holes 16 in the housing 15 of the door closer 10, and the screws 40 are easily inserted through the holes in the direction of the mounting plate 11. This is applied after the installation movement of the door closer 10 on the mounting plate 11 is completed, so that the door closer 10 is fixed in the opposite direction to the mounting plate 11 in the fixed direction 14. The screw 40 can be inserted into the hole 16 of the casing 15 by a service technician until the screw 40 is threaded into the hole 18 of the projection 17 of the mounting plate 11, and the mounting plate 11 is fixed to the mounting plate 11 in the fixed direction 14 of the door closer 10.

The special arrangement of the hole 16 in the housing 15 of the door closer 10, and thus the arrangement of the screw 40 relative to the mounting plate 11, results in an easy, quick and proper installation and warranty of the door closer 10 on the mounting plate 11, and thus a door closer The combination 1 is easy, quick and proper to install and secure on a support member, such as, for example, a door leaf, a door sill, a wall, a ceiling or the like. In particular, the locking of the door closer 10 on the mounting plate 11 can be carried out in a non-contaminating and interference-free position. The interference-free position means that the door closer 10 is secured by the additional fixation of the screw 40 to ensure that the screw 40 is outside of the operating door closer combination 1, particularly the hand movement of one of the handles of the door closer combination 1. The design of the normal vector 20 perpendicular to or substantially perpendicular to the mounting plate 11 ensures easy access to the screw 40 and isolates the screw 40 from a tuning valve screw, which is typically provided to the housing 10 of the door closer 10 Front side.
