The aim of the invention is to provided a cover part for a floor spring, which can be used in a universal manner, irrespective of whether the floor spring has a floating shaft or a rigid shaft and whether the cover plate (12) is fixed to the cement body (14) or to the housing of the floor spring, which requires no pre-assembly on the part of the manufacturer and which facilitates a retroactive installation even in a mounted door. To achieve this, the cover part is configured in two parts and consists of a substantially U-shaped base part (1) and an insert (2) that can be introduced into said base part (1).

Description

  The present invention is a floor spring with a casing for accommodating a closing mechanism, the casing being of the type covered by a cover component in the region of a floor spring shaft that supports a door or the like About.

  Such floor springs are widely known. The floor spring has a casing, and the casing is surrounded by a cement box that can be inserted into a notch provided in the floor. Since the entire cement box including the floor spring located inside is covered by the cover plate upward, only this cover plate can be seen from the outside. The cover plate can only be assembled after the door or the like has been assembled to the floor spring, and even for the first time after adjusting the closing speed of the floor spring, for example, so that the cover plate is on the side of the floor spring shaft. In order to assemble it into the casing of the floor spring, it must have a slot extending in the longitudinal direction on the end face.

  The cover plate can be fixed to a cement box or a floor spring casing. Since the floor spring casing must be adjustable in all four planes in the cement box, various lengths of length are associated with the various means described above for securing the cover plate to the cement box or casing. A hole is formed in the cover plate.

  When the cover plate is fixed to the casing of the floor spring, the cover plate may perform adjustment movement of the casing in the cement box together with the casing. Therefore, the slot must be sized so that the cover plate can be assembled through the side of the floor spring shaft.

  On the other hand, when the cover plate is assembled to the cement box, the casing moves relative to the cover plate during the adjustment movement because the cover plate is fixedly coupled to the cement box. Again, to ensure complete adjustment of the casing, the slot must be enlarged by an additional adjustment distance. This is because the floor spring shaft may collide with the cover plate.

  Furthermore, in order to protect the floor spring and in particular the sealing member surrounding the floor spring shaft from contamination, the slot must be covered by one or more suitable cover components.

  In practice, one and the same floor spring is used both with the plug shaft and with the fixed shaft. This requires a variety of cover components for one and the same floor spring, depending on the configuration of the shaft and the fixing of the cover plate to the casing or cement box. This increases the effort for manufacturing and school management.

  Since the assembly by the customer in the field has no track record for various reasons, these components are partially assembled in advance at the factory.

  Therefore, the object of the present invention is to use it freely regardless of whether the floor spring has an insertion shaft or a fixed shaft, and whether the cover plate is fixed to the casing of the cement box or the floor spring. It is an object of the present invention to provide a cover component that can be assembled later, even in an already assembled door, without the need for prior assembly by the manufacturer.

  In order to solve this problem, in the configuration of the present invention, in the floor spring of the type described at the beginning, the cover component part is formed of two parts, a substantially U-shaped base part, and an insertion that can be inserted into the base part. It consisted of the body.

  The arrangement according to the invention provides a freely usable cover component that can be used independently of the structure of the floor spring, does not require prior assembly by the manufacturer, and can be incorporated even in already assembled doors. .

  A second aspect of the present invention is described below.

  According to an advantageous configuration, the base and the insert are assembled and have a substantially square outer contour. This makes it possible to produce both components easily and inexpensively and to ensure simple retention.

  Advantageously, the base can be inserted into the insert in a substantially flat shape, thereby providing a cover component with a small required space in the assembled state.

  If the insert can be inserted in an advantageous manner so that a circular opening is formed in the base for passing through the floor spring shaft, a plug or fixed shaft can be used as required.

  Advantageously, the open side of the U-shaped base can be fitted over the insert. As a result, the cover component can be easily and easily assembled around the floor spring shaft.

  With an advantageous configuration, if the inner edge of the base engaging the insert is provided with a concavely shaped semicircular, longitudinally extending recess, it is simple and good for the insert at the base A simple position fixing means is formed.

  According to an advantageous configuration, if the outer edge of the insert is provided with a wing projecting outward on the side, and the wing engages a recess provided in the inner edge of the base, the position fixing is possible. Further improvement.

  Advantageously, a semicircular contour is provided in the area of the base and the insert facing the floor spring shaft, the shape of which is formed as a seal lip, which is connected to the floor spring shaft. Engage with the groove provided. Such a configuration guarantees good protection against intrusion of impurities. This sealing lip can be formed in the form of a radial seal.

  According to another advantageous configuration, if the sealing lip is inclined upwards, a pocket is created at the end of the sealing lip where impurities can be collected. Therefore, the entry of impurities into the floor spring is effectively prevented.

  In order to ensure a good positioning between the base and the insert, the stomach, according to a particularly advantageous configuration, has an insert in the rear region of the outer edge, each with a notch, the notch Each one can be locked to one locking projection provided on the inner edge.

  In order to allow easy introduction of the base and the insert, an introduction ramp is advantageously provided at the base.

  According to another advantageous configuration, the insert and the base have a target break at the end opposite the floor spring shaft. This allows the base and insert to be easily adapted to the local conditions.

  Advantageously, the insert has a slight thickness than the base. With such a simple configuration, the base and the insert can be firmly clamped with only one screw. This is because the insert is relatively thin so that the insert clamps the base when the screw is tightened.

  The cover component according to the invention is preferably manufactured from plastic, in particular POM, as the base and the insert as injection-moulded parts. This guarantees simple and inexpensive manufacturing even when the number of parts is large.

  Other features and advantages of the cover component according to the invention will become apparent from the description of the advantageous embodiments described below.

  The cover component according to the invention consists of a base 1 and an insert 2. The base 1 is shown in various views from FIGS. 1 to 8, and the insert 2 is shown in various views from FIGS. 9 to 13.

  First, the base 1 will be described. This base 1 is manufactured from plastic, for example POM, for example by injection molding. The base 1 is formed as a substantially flat plate having a longitudinal notch opened on one side, whereby a substantially U-shaped shape is shown in a plan view. The base 1 is provided with a semicircular recess 3 formed in a recess shape and extending in the longitudinal direction of the notch at the inner edge of the notch. The end face of the notch ends with a semicircular contour 4 in plan view. The contour part 4 is provided with a seal lip 5 directed inward. The seal lip 5 is inclined and directed obliquely upward (see FIG. 5). A sealing lip 5 whose profile can be formed like a radial seal engages a groove (not shown) in the floor spring shaft 10 of the floor spring to prevent entry of contaminants. On the inner edge of the notch provided in the base 1, one locking projection 8 is provided on each side of the rear region. Furthermore, an introduction slope 11 that facilitates the joining of the base 1 and the insert 2 is disposed at the inner edge of the notch. In order to adapt the base 1 to the respective situation in the longitudinal direction, a plurality of target breaking points 16 are provided at the free end, and the legs of the base 1 can be easily shortened by the target breaking points. .

  An insert 2 that can be inserted into the base 1 is shown in FIGS. 9 to 13. The insert 2 is made of a plastic injection-molded part, for example, POM, like the base 1, and has a substantially square shape with a semicircular contour 4a on the narrow side. A blade 6 projecting outward is provided at the outer edge of the insert 2, and this blade 6 can be engaged with a recess 3 provided at the inner edge of the base 1. The wing 6 has a contour that fits into the recess 3. By the cooperation of the recess 3 in the base 1 and the wing 6 in the insert 2, good fixing of both parts can be obtained. The semicircular contour 4 a on the narrow side of the insert 2 forms a seal lip 5 a and corresponds to the shape of the contour 4 of the seal lip 5 provided on the base 1. In the region of the wing 6, a notch 7 is provided in the end region of the insert 2, and this notch 7 is a locking projection provided on the base 1 for locking between the base 1 and the insert 2. 8 can be engaged, and relative sliding of both parts is prevented. Further, the insert 2 is provided with a target breaking portion 16a, and the length can be adjusted to the local conditions as with the base portion 1.

  14 and 15 show a state in which a cover constituent portion including the base 1 and the insert 2 is assembled. The recess 3 provided in the base 1 is engaged with a wing 6 provided in the insert 2, and the semicircular contours 4 and 4 a release a region for allowing the floor spring shaft 10 to pass therethrough. . As can be seen from FIG. 15, the insert 2 has a slightly higher height than the base 1. As a result, a height difference h occurs. The significance thereof will be further described later with reference to FIGS.

  FIG. 16 is a plan view of the finally assembled floor spring. In this case, the door is not shown for easy viewing. A floor spring (not shown) is covered by a cover plate 12, and the floor spring shaft 10 extends through a cover component portion including the base portion 1 and the insert 2. The insert 2 of the cover component is fixed to the casing of the floor spring by screws 9 and clamps the entire cover component based on the above-described height difference h between the base 1 and the insert 2.

  Next, the assembly of the cover component will be described with reference to FIGS. When the cover component is attached, the floor spring casing 15 is secured and oriented to a cement box 14 provided on the floor.

  First, as shown in FIG. 17, the insert 2 is tilted from the upper right side, for example, and slid along the floor spring shaft 10, and inserted in the arc shape to the left as shown by the arrow in FIG. Rotate until the body 2 is oriented parallel to the floor spring casing 15. Next, the insert 2 is fixed to the casing 15 with screws 9 in advance. In this case, the screw 9 is not yet tightly clamped, i.e. the insert 2 can still move and slide in the height direction. The base 1 is now fitted over the insert 2 and the recess 3 engages the wing 6. At the end of the insertion movement, the locking protrusion 8 of the base 1 engages with the notch 7 of the insert 2 and fixes the base 1 and the insert 2 so as to form one unit. After the base 1 is locked to the insert 2, the screw 9 is finally tightened, and thus the base 1 is firmly clamped via the insert 2. The defined clamp of the cover component is obtained by the height difference h between the base 1 and the insert 2. Since the insert 2 has a smaller height than the base 1, when tightening the screw 9, the insert 2 is pushed downward, thus simultaneously clamping the base 1. After the screw 9 is tightened, the cover plate 12 is slid below the cover component and fixed to the cement box 14 or the floor spring casing 15 by the fixing screw 13.

  As can be seen from the above description, the already installed door can be assembled without any problem. Similarly, the free use of the cover component according to the invention can also be obtained when the cover plate 12 is fixed to the cement box 14 or the floor spring casing 15 in both the plug-in shaft and the fixed shaft.
