The invention relates to a door closer of floor, with a housing to accommodate a closing mechanism, being the casing covered by a coating component in the area of an axis of the closing device that supports a door or Similary.

Door closers of this type are what sufficiently known. They have a housing surrounded by a box  recessed that can be inserted into a hole in the ground. The built-in box completes with the floor door closer housed in it is covered upwards by means of a plate coating, so from the outside only this plate is visible covering. Because the cover plate can mounted only after installing a door or similar on the floor door closer and also only after adjusted for example the closing speed on the door closer of floor, the cover plate has to present on one side front an oblong hole that runs in the longitudinal direction so that the cover plate can be mounted on the housing of the floor door closer in front of the device shaft of closing.

The cover plate may be fixed in the recessed box or the floor door closer housing. Because the door closer housing needs to be adjusted floor in the box embedded in the four directions in the plane, in relation to the fixing options above mentioned of the cover plate in the recessed box or in the housing results in oblong holes of different sizes in the cover plate.

When the cover plate is fixed on The floor door closer housing is carried out together with the case a possible adjustment movement of the case in the case recessed The oblong hole must therefore be so large that it is possible to mount the cover plate in front of the axis of the closing device.

When the cover plate is mounted on the built-in box, the housing performs a relative movement with respect to the cover plate during a movement of adjustment, since it is firmly attached to the recessed box. In order to guarantee a complete adjustment of the housing, the oblong hole must be enlarged by the path of additional adjustment, since otherwise the axis of the device Closure can hit the cover plate.

It is also necessary that the oblong hole be coated by one or more coating components appropriate for the floor door closer, and in particular a gasket surrounding the axis of the closing device, be protected against dirt.

In practice, the same is also used floor door closers with both a removable shaft and a rigid shaft, so for the same floor door closer they need depending on the type of shaft and plate fixation coating on the housing or in the recessed box, respectively, different coating components, which it entails increased expenses with respect to manufacturing and storage.

In addition to the above, these components are partially assembled in the factory, since for the most diverse reasons no on-site assembly has been accredited by the customer.

Document DE 28 40 726 presents a plate of two-part coating for a compliant floor door closer to the preamble of claim 1 that can be aligned by a anchor supported loosely. The anchor has a groove that allows to place it in the desired position before screwing the plate of covering with two screws in the aligned anchor.

The object of the invention consists in both in designing a coating component that can be used in Universal form, regardless of whether the floor door closer It has a removable shaft and a rigid shaft and independently of whether the cover plate is fixed in the recessed box or in the floor door closer housing, and that does not require a pre-assembly by the manufacturer and facilitate assembly rear even with the door installed.

This goal is achieved in a door closer of soil of the type initially explained by the characteristics of claim 1. The coating component comprises a Essentially U-shaped base piece as well as a piece of insert that can be inserted interlockably in the piece base, thus creating a fixation for the piece of insertion in the base piece.

By means of the configuration according to the invention, creates a universally applicable coating component that can be used regardless of the type of construction of the floor door closers, you do not need a previous assembly by the manufacturer and can also be mounted with the door installed.

The dependent claims comprise other configurations of the object of the invention.

According to an advantageous variant, it is provided that the base part and the insert present in assembled state  an outer contour in essentially rectangular. This facilitates a Simple and economical manufacturing of both components and guarantees Also a simple storage.

Because the base piece can be inserted advantageously essentially flat in the piece of insertion, a coating component is created that requires little space in mounted state.

When according to a preferred configuration of the insert can be inserted in such a way in the base piece that a circular opening for the passage of the axis of the closing device, according to need it is possible to use an axis of remove and put or a rigid shaft.

The U-shaped base piece can slide preferably with its side open on the insert, so the coating component can be mounted so easy and simple.

It creates a simple possibility and yet good for fixing the insert in the base piece, since the base piece is provided on its inner edges, which can be couple with the insert, with semicircular concavities and concavely molded that extend in the direction longitudinal.

The fixation is further refined by the fact that the insert has its outer edges  protruding wings laterally outward that are introduced into the concavities at the inner edges of the base piece.

Advantageously, the base piece and the piece of insertion are provided in their areas directed to the axis of the closing device of a semicircular contour whose profile is configured as a shutter skirt that is inserted into a slot on the axis of the closing device. Due to this configuration it guarantees good protection against dirt penetration. The shutter skirt can be set as a ring radial shutter

In particular when according to another variant advantageously the shutter skirt is obliquely directed upwards, at the end of the shutter skirt a bag in which dirt can accumulate. This way you can effectively prevent the penetration of dirt in the door closer of soil.

In order to ensure a good fixation of the base piece and insert, the insert is provided with a notch in the back area of each edge exterior that can be interlocked with a respective protrusion of retention provided on the respective inner edge of the piece base.

To facilitate a simple insertion of the base piece and insert, in the base piece are Advantageously provided input bezels.

According to an advantageous variant, the piece of insert and base piece are provided with break points controlled at its ends opposite the axis of the device closing. This facilitates a simple adaptation of the length of the base piece and the insert at local conditions

The insert advantageously presents a thickness smaller than the base piece. Thanks to this configuration simple it is possible to tighten the base piece and the insert with a single screw, since the thinnest insert is fixed the base piece by tightening when tightening the screw.

The coating part according to the invention is preferably manufactured by injection molding of plastic, for example of POM. This guarantees a Simple and economical manufacturing also in large quantities.

Other features and advantages of the component coating according to the invention follows from the following Description of a preferred embodiment.

A coating component comprises a base part 1 and an insert 2. The base part 1 is shown in different views in figures 1 to 8 while the piece of Insert 2 is represented in different views in Figures 9 to 13.

The following describes first the base part 1. Base part 1 is for example molded by plastic injection, for example from POM. It is set as Essentially flat plate with an open oblong notch to the side, so that you have the plan view from above essentially a U-shape. On the respective inner edges of the notch, the base part 1 is provided with concavities 3 concavely shaped semicirculars that run in the longitudinal direction of the notch. The front side of the notch is finished by a semicircular contour 4 in plan view from above. The contour 4 is provided with a shutter skirt 5 that is directed inwardly and in shape oblique up (see figure 5). The shutter skirt 5, whose profile can be configured as a sealing ring radial, is inserted into a slot not shown on an axis 10 of the closing device of the floor door closer and prevents from this dirt penetration way. On the inner edges of the notch in the base part 1 is provided in the rear area to each side a respective retention highlight 8. Also, in the internal edges of the notch are arranged bevels of input 11 that facilitate the assembly of the base piece 1 and the insert 2. To adapt the length of the base part 1 to the respective conditions, the base part 1 is provided with points 16 controlled break at its free ends that allow shortening in a simple way the arms of the base piece 1.

Figures 9 to 13 show the piece of plug-in insert in the base piece 1. It is composed, just like the base piece 1, of a plastic injection molded part, by POM example, and essentially presents a rectangular shape with a semicircular contour 4a on a narrow side. On its edges outside, insert 2 is provided with wings 6 protruding outwards that can be coupled with concavities  3 on the inner edges of the base piece 1. The wings 6 have such contour that fit into the concavities 3. Due to the action joint of the concavities 3 in the base piece 1 and of the wings 6 in insert 2 can achieve a good fixation of both pieces The semicircular contour 4a on the narrow side of the insert 2 forms a shutter skirt 5a whose shape corresponds to the contour 4 of the sealing skirt 5 in the piece base 1. In the area of the wings 6 a notch 7 is provided in an end zone of the insert 1 that can be coupled with the retention projections 8 in the base piece 1 to lock the base piece 1 with insert 2 and to avoid this way a relative displacement between the two pieces. Likewise, breakage points are provided in the insert 2 controlled 16a to facilitate, as in the base piece 1, a Length adaptation to local conditions.

In figures 14 and 15 it is shown in state assembled the composite coating component of the piece base 1 and insert 2. The concavities 3 in the piece base 1 are coupled with wings 6 in insert 2 and the semicircular contours 4 and 4a leave an area free for axis 10 passage of the closing device. In figure 15 you can It is also appreciated that the insert 2 has a height lower than that of the base piece 1, so it is a difference in height h whose meaning is explained below in relation with figures 17 to 20.

A plan view is shown in figure 16 from above the fully assembled floor door closer, for greater clarity the door has been suppressed. The floor door closer invisible is coated with a cover plate 12 and it extends with its axis 10 of the closing device through the coating component consisting of the base part 1 and the insert 2. The insert 2 of the component coating is fixed on the floor door closer housing using a screw 9 and fix by tightening the component of full coating due to the difference in height h previously mentioned between the base piece 1 and the piece of insert 2.

The assembly of the coating component is explained below with reference to figures 17 to 20. When the coating component, a housing 15 of the closing device of the floor door closer is fixed and fitted on the floor in a recessed box 14.

As shown in Figure 17, first place the insert 2 slides towards the axis 10 of the closing device, for example inclined from above to right down, and turn following a circular arc to the left, as indicated by the arrow in figure 17, until the insert 2 is oriented parallel to the housing 15 of the closure device. Insert 2 is fixed previously in the housing 15 of the device closing by screw 9. Screw 9 is not yet tightened firmly, that is, it is still possible to move the piece of Insert 2 and move it in height. Then the base piece 1 slides over the insert 2, coupling the concavities 3 with wings 6. At the end of the plug movement retaining projections 8 of the base part 1 are interlocked in notches 7 on the insert 2 and thus fix the base piece 1 and insert 2 in the form of a unit. After the interlocking of the base part 1 in the insert 2 is tighten the screw 9 and the base part 1 is fixed by tightening using insert 2. A defined tightening of the component  of coating is achieved by the difference in height h between the base piece 1 and the insert 2. Because the insert 2 has a lower height than the base piece 1, insert 2 is pressed down when pressed screw 9, so fix by tightening the part at the same time base 1. After tightening screw 9, the cover plate 12 slides below the coating component and is fixed in the recessed box 14 or in the housing 15 of the closure device by fixing screws 13.

As follows from the description above, a smooth installation is facilitated even with the door installed. The universal application of the component also occurs. of coating according to the invention for both removable shafts and put as well for rigid shafts and with a plate fixation covering 12 in the recessed box 14 or in the housing 15 of the closing device
