DE19942333C2 - Corner protection for the transition from the step to the riser support in the inside corner of a staircase - Google Patents

Description

The invention relates to a corner protection for the transition from the kick to Riser pad in the inside corner of a staircase.

It is widespread that stairs have a stair pad that consists of a Step support and a riser support exists. This kick and Riser pads are mostly glued on. A corner protection of the considered Art has the task of facing each other at the inner corners of the steps facing and covering the end area of the step and riser supports protect. One problem is that in practice different strengths Stair pads can be used.

The present invention has for its object a corner protection considered type to indicate that for different thickness stair pads is usable.

This object is achieved according to the invention by the features of patent claim 1 solved.

Advantageous embodiments of the invention are in the subclaims characterized.

Details of the invention emerge from the following description as well as with the accompanying drawings. Show:

Fig. 1 shows a vertical section through an embodiment of a corner protector with a two-part profile bar and

Fig. 2 shows a vertical section of the inner corner of the basic construction of a concrete step with a staircase support and the corner protector of FIG. 1.

In the following, reference is first made to FIG. 1.

A partial profile bar ( 2 ) resting on a basic construction consists of two profit legs ( 1 , 2 ) that are at right angles to each other and two legs ( 3 , 4 ) that point inward at an angle of 45 ° from the inside corner, which are spaced apart by one another Form U-shaped recess ( 5 ) for receiving the section bar ( 1 ) with its leg ( 10 ). The end of the two 45 ° legs ( 3 , 4 ) extends at an angle of 45 ° and is slightly rounded on the inside. The inside of the two profile legs ( 3 , 4 ) have a Z-toothing ( 6 ) in the outer area, the rest ( 7 ) is set back by the toothing and smooth. At the same distance from the corner, two further legs ( 8 , 9 ) are attached at right angles to the profile legs ( 1 , 2 ), the leg ( 9 ), which is attached to the vertical leg ( 2 ), in the outlet with the 45 ° leg ( 3 ) is connected. The leg ( 9 ) is somewhat stronger for reinforcement in the attachment area and therefore tapers upwards. The leg ( 8 ), which is attached to the horizontal leg ( 1 ), ends at a certain height at an angle of 45 ° to the corner.

The partial profile bar ( 1 ) consists of a profile leg ( 10 ) which has opposite Z teeth ( 11 ) to the Z teeth ( 6 ) of the partial profile bar ( 2 ) on both sides. The leg ( 10 ) runs out at the bottom in a V-shape and is attached at the top in the middle at a right angle to the outwardly profiled end cap ( 12 ). The end cap ends on both sides at the same distance from the leg ( 10 ) at an angle of 45 ° ( 13 ). At the front, the end cap has a slight fillet ( 14 ) in the center, which gently curves ( 15 ) towards the front and outside.

The partial profile bar ( 1 ) is driven with its leg ( 10 ) into the U-shaped recess ( 6 ) of the partial profile bar ( 2 ) and held in place by the opposite Z-toothing ( 6 , 11 ). The 45 ° surfaces ( 13 ) of the end cap of the partial profile bar ( 1 ) then rest on the stair pads of the step and riser and form the inner corner protection.

When installed, only the end cap ( 12 ) with its profile ( 14 , 15 ) can be seen. Due to the adjustment range of the partial profile bar ( 1 ) in the U-shaped recess of the partial profile bar ( 2 ), this two-part profile bar can be used for stair pads of different thicknesses.

In Fig. 2 the inner corner area of the basic construction of a concrete step ( 19 ) with a stronger stair support ( 20 ) is shown on the step and riser with the two-part profile bar as inner corner protection.

These inside corner profile bars can also be used for stair renovation.

The partial profile bar ( 2 ) is glued, screwed onto the basic construction of the stairs in the inner corner or both. The tread and riser pads are fitted and glued on, the tread pad extending to the leg ( 8 ), and the riser pad is placed on the leg ( 9 ). Finally, the partial profile bar ( 1 ) is driven with its leg ( 10 ) into the U-shaped recess ( 5 ) of the partial profile bar ( 2 ) until the surfaces ( 13 ) rest on the tread and riser pads and are held in place by the opposite Z-toothing become. The end cap holds the step and riser support and forms a gracefully curved transition as inner corner protection.
