Abstract

A device for forming a transition bridge between two adjacent floor coverings of different heights is proposed, in which an end shank is molded onto an attachment shank to be installed under the floor covering of greater height, at an approximately right angle. This end shank is connected with a transition shank which is angled down from the horizontal at an angle of 20° - 45°
and supports itself. This device is a single-piece unitary construction with an attachment shank provided with passages, which are preferably less than 1.5 mm thick, and with a transition shank molded onto one side of the end shank. Shank has a contact section for the adjacent floor covering of lesser height, at its outer end.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention The invention relates to a device for forming a transition or bridge between two adjacent floor coverings of different heights, in which an end shank is molded onto an attachment shank to be installed under a floor covering, at an approximately right angle, which end shank is connected with a transition shank which is angled down at an angle of 20~ to 45~, and supports itself.
2. The Prior Art A device such as a removable bridging profile for floor joints, is known from DE-GM 87 17 225. It consists of an L-shaped basic profile, the attachment shank of which is installed in the parquet floor covering, which has been appropriately hollowed out. There is also the transition profile which has approximately a T-shaped cross-section and is applied and attached to the end shank, which is molded onto the attachment shank at a right angle. The two stay sections of the T can be bent downward, with the inner stay section covering the edge section of the parquet floor. The outer stay section forming a transition shank rests on the other adjacent floor covering with its end. The base for the parquet floor is at the height of the adjacent floor covering in this case. Such a device is therefore only suitable for forming the transition from a higher floor covering to the base, since the transition shank only forms a bridge, and not 26045-18(S) an end section for another adjacent floor covering. It is also disadvantageous that such a device consists of two pieces and that the basic profile has to be placed onto the base with additional means of attachment.
In the renovation of old buildings and in remodel-ling, the problem often occurs that floor sections covered with ceramic tile are directly adjacent to other floor sections, which might be covered with a carpet or with a plastic material, for example. The heights of the adjacent floor coverings are therefore different, so that a step is formed in this adjacent area. Frequently it is not possible or not desirable to raise the existing floor area with the lower floor covering.
In order to support the edge step at the ceramic tile area and to protect it, it is known from DE-GM 75 19 945 to lay an angled profile under the ceramic tiles which are at the edge, with an attachment shank provided with passages, which is less than 1.5 mm thick. Approximately perpendicular to this attachment shank, 26045-18(S) :~o~7 4~
there ls an end shank molded on, whlch forms an allgned edge for the ceramic tlles. When there ls a lower floor coverlng, for example a carpet covering, such an angle proflle is arranged at the carpet edge wlth the outslde of lts end shank.
Then the ceramlc tlle of the adjacent floor sectlon is applied from the inside of the end shank. Thls causes an undeslrable step between the lower carpet coverlng and the ad~acent ceramlc tlle coverlng ln the area of the built-ln angle profile.
SUMMARY OF THE INVENTION
An ob~ect of the invention is to provide a device for forming a transition or bridge between a ceramlc tlle covering and an adjacent, dlfferent floor coverlng wlth a dlfferent helght, whlch can be attached ln slmple manner and covers the frontal ends of both floor coverlngs.
The lnventlon provldes a devlce for formlng a transltlon brldge between two adiacent floor coverings with one floor covering of a greater helght and the other floor coverlng of a lesser helght comprising an end shank having an upper end and a lower end; an attachment shank formed at an approximately rlght angle onto the lower end of sald end shank, and lnstallable under the floor coverlng of greater helght, sald attachment shank lncludlng openlngs therethrough to be penetrated by adheslve durlng lnstallatlon when the attachment shank is to be adhered to a floor surface; a transltlon shank havlng a first end and a second end with the first end lntegral wlth sald upper end of sald end shank and angled downwardly from the horlzontal at an angle of 20~ -- 26045-18(S) B

45~, said transition shank being self-supporting: a contact section havlng an upper end attached to the second end of the transition shank, said contact section havlng an outer end for placement ad~acent to the floor covering of lesser height, and a lower end that is substantlally co-planar with said attachment shank; and said device comprising a single piece bridge of unitary construction.
The device accordlng to the inventlon ls formed preferably by a single-piece profile constructed as a unitary bridge made of metal or plastic, whlch can be applied and attached e.g. under ceramlc tiles via the attachment shank, in simple manner, without addltlonal height being required for this. The clear height of the end shank corresponds to the height of the ceramic tile, and the openings of passages in the shank are penetrated by the adhesive layer to improve bonding to the smooth floor.
From the other side, the ad~acent floor covering is applled, and it also ends ln allgnment wlth the contact section of the transitlon bridge shank. The transitlon brldge shank ltself forms the gradual transitlon, wlthout a step, from the lower floor covering to the higher floor covering.
This avolds having a step.
In order to achieve lmproved strength for the transition brldge shank, a supportlng shank, preferably of lnverted T-shaped cross-section, can be provlded on lts underslde. In addltlon, an attachment stay facing towards the inside can be provided at the lower end of the contact B 26045-l8(s~

sectlon, which stay also acts as a support and serves to keep the adhesive or mortar in place.
In a further embodiment, a widened section can be molded on, approximately parallel to the attachment shank, which improves the formation of a ioint to be filled with mortar or adhesive, and thereby improves the edge protection for the ceramic tile.
BRIEF DESCRIPTION OF THE DRAWINGS
Other features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawing which discloses one embodiment of the present invention. It should be understood, however, that the drawing is designed for the purpose of illustration only and not as a definition of the limits of the invention.

B 26045-l8(S) In the drawing wherein similar reference characters denote similar elements throughout the several views:
FIG. 1 shows a cross-section of the bridge installed between two floor coverings having different heights; and FIG. 2 shows a front view of the bridge of Fig. 1.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Turning now in detail to the drawings, FIG. 1 shows a smooth floor 1, for example with a plaster finish, having a transition means or bridge 4 being formed between a carpet covering 2 and a ceramic tile floor covering 3. The bridge 4 forms the transition, without there being a step. This bridge has an attachment shank 41 positioned under the ceramic tiles 3. The attachment shank is held firmly and is fixed in its location by means of a thin layer of adhesive 5. The part of this bridge 4 which extends towards the outside is also attached with correspondingly applied adhesive 5 such as mortar, which can be wedged into position behind the attachment stay 432 and the supporting shank 433.
As can be seen from FIG. 2, the attachment shank 41, which can be less than 1.5 mm thick and is provided with passages 411, serves to attach the bridge 4 under the ceramic tiles. Its end shank 42, which stands at an approximately right angle to the attachment shank 41, and is adapted to the height of the ceramic tile 3 to be finished, protects the frontal edge of the ceramic tile after installation. Facing towards the inside, a widened section 421 is provided at the upper end of this end shank 42. Facing towards the outside is 26045-18(S) the transition shank 43, which is molded onto the end shank 42. Transition shank 43 iS downwardly inclined at an angle A
of 20~ to 45~, and preferably 30~. Angle A is defined as the angle between the transition shank 43 and the horizontal line H that passes through widened section 421.
The outer end of this transition shank is formed by the contact section 431, which is approximately perpendicular to the attachment shank 41. The contact section 431 continues on as an angled attachment stay 432 facing towards the inside of the device. To enable the transition shank 43 to carry a heavy weight, there is also provided a supporting shank 433 with an approximately inverted T-shaped cross-section. Shank 433 iS molded onto the bottom surface 438 of shank 43 approxi-mately at the center of the bottom of the transition shank 43.
The bottom of the attachment shank 41, the bottom of the supporting shank 433, and the bottom of the attachment stay 432 are all in the same plane.
If the transition bridge device is to be made from plastic, then it can be manufactured, for example, from either thermoplastic or thermosetting material by the injection mold-ing of plastic powder.
If the transition bridge device is to be made from metal, then it can be manufactured, for example, by molten metal casting, or by extrusion through a die.
While only a single embodiment of the present in-vention has been shown and described, it is to be understood 26045-18(S) that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention as defined in the appended claims.
