DOOR FITTING UNIT The invention relates to a door fitting unit, in particular a pivot patch for a glass door, comprising a first and a second element, which elements are each provided with connecting means for connecting the elements detachably to each other, which first and second elements are each provided with a first flank, which can be fitted on the one and the other side of the door respectively, in order to fix a door part between at least a part of the first and second element, and each of the elements comprising a base piece and a top piece, on which base piece said connecting means are provided, which base piece is provided with a first fixing profile, and which top piece is provided with a second fixing profile, the first and the second fixing profiles being complementary, and all the above being such that the top piece can be mounted on the base piece. Such a door fitting unit is known from GB 1093513 and AU 745962 and serves, inter alia, as a pivot patch or door handle. The first and second elements are fitted on either side of the door, in order to fix a door part. The door fitting unit is connected to the door by means of the connecting means. After the base pieces have been mounted on the door part, said base pieces are covered by means of the top pieces. For that purpose, the second fixing profile has an outside contour which corresponds entirely to the contour of the top piece and to the outside contour of the base piece. A disadvantage of the known door fitting units is that the first and second elements are in each case made of a solid piece, and that the top piece is purely a cover plate. This means that the designers of such door fitting units have only few possibilities for changing the external appearance of the door fitting unit. The fact is that the designer is tied to the contours of the base piece as far as the top piece is concerned.
The object of the invention is to achieve a door fitting unit in the case of which it is possible, starting from the same base piece, to achieve several variations of the external shape of the door fitting unit. To that end, a door fitting unit according to the invention is characterized in that the first fixing profile is provided on a second flank of the base piece situated opposite said first flank, and the second fixing profile is provided on an inside flank of the top piece and does not form part of the outside contour of the top piece. Owing to the fact that the first fixing profile is provided on the second flank of the base piece, the entire surface of said second flank is available for this first fixing profile, and not just the outside contour of the base piece. Furthermore, owing to the fact that the second fixing profile does not form part of the outside contour of the top piece, the designer is no longer tied to these contours, and the outside contour of the top piece can be of any desired shape. Since, furthermore, the second fixing profile is provided on the inside flank of the top piece, there too the entire surface is available, so that a solid connection between top piece and base piece can be achieved. The designer can therefore give all sorts of shapes to the top piece without adversely affecting the solidity of the construction itself, since the contours of the base piece are no longer the determining factor. A first preferred embodiment of a door fitting unit according to the invention is characterized in that the top piece is provided slidably on the base piece. This makes a simple mounting of the top piece possible. A second preferred embodiment of a door fitting unit according to the invention is characterized in that the first and second fixing profiles are substantially T-shaped. T-shaped profiles are easy to achieve and permit good and reliable mounting. The first fixing profile preferably has a rounded top end. This makes the mounting of the top piece easier.
The invention will now be described in greater detail with reference to the drawing, in which: Figure 1 shows a door fitting unit, in particular a pivot patch, according to the invention on which a glass door is mounted; Figures 2 a) to d) show the base pieces and the top pieces; Figures 3 a) to d) show a front view of the base pieces and the top pieces; and Figures 4 a) to d) show a top view of the base pieces and the top pieces. In the drawing the same part or a corresponding part is given the same reference numeral. Figure 1 shows a pivot patch 1 on which a glass door 2 is mounted. For the sake of simplicity, a pivot patch on a glass door has been selected as an exemplary embodiment, but it will be clear that the invention is not limited to a pivot patch, or to the use on a glass door. Use on other door fitting units such as door handles or hinge parts on doors with glass or other material is, of course, not ruled out. The pivot patch 1 comprises a first element 3 and a second element 4, the first element being fitted on the one side and the second element being fitted on the other side of the door 2. As shown in Figures 2 and 3, each element comprises connecting means 10, 11 and 12 for connecting said first and second elements detachably to each other. In the figures said connecting means are formed by screw thread 10 and 11 in the elements and a set of screws 12, which project through the second element 4 and the door 2 in order to engage in the screw thread 11 of the first element. Of course, connecting means other than screws and screw thread are possible, such as a clips or pin system. The first and second elements are each provided with a first flank 6-1 and 7-1 , which comes into contact with the leaf of the door when the door is mounted on the pivot patch. The first flank extends
virtually perpendicularly from a foot 13-1 and 13-2 in which the pivot pin of the door engages. The first flank 6-1 is fitted against one side of the door, while the first flank 7-1 is fitted against the other side of the door. The first and second elements further each comprise a base piece 6 and 7 respectively, on which the connecting means are provided. The first and second elements also comprise a top piece 8 and 9. In order to put base piece and top piece together, each base piece is provided with a first fixing profile 14 and each top piece with a second fixing profile 15. The first and second fixing profiles are complementary. The first fixing profile 14 is provided on the second flank 6-2 and 7-2 of the element, which second flank is situated opposite the first flank 6-1 and 7-1. The first and second fixing profiles are substantially T-shaped, the vertical part of the T-shape being in a position virtually perpendicular to the second flank, while the horizontal part of the T-shape extends in a position virtually parallel to the second flank. Owing to the fact that the first fb ixing profile 14 is provided on the second flank 6-2 and 7-2 of the base pi ece, it is possible to use the entire surface of said second flank for the fi rist fixing profile. The second fixing profile 15 is provided on an inside flank of the top piece. The term inside flank here means the flank which is positioned transversely relative to the base piece. The fact that the second fixing profile is provided on said inside flank offers the possibility of using the entire surface of said flank for the second fixing profile. A solid construction of first and second fixing profiles is consequently possible, which in turn helps to create a great variation in the top pieces, without any restriction on them from the dimensions of the fixing profiles. In contrast to the known top pieces, in the top piece according to the invention the outside contour of the base piece is not the determining factor for the contours of the top piece, since the presence of the fixing profiles on the second flank of the base piece and the inside
flank of the top piece no longer make it necessary for the outside contour of the top piece to be part of the second fixing profile. For mounting of the top piece 8, 9 on the base piece 6, 7 it will suffice to slide the top piece over the first fixing profile making use of the second fixing profile. The top piece is slid fully over the first fixing profile until it comes to rest upon the foot 13-1 , 13-2. As shown in Figure 2, the connecting means 10 are situated on the first fixing profile 14. It is preferable for a countersink 16 to be provided in order to allow the screw 12 to sink into the T-shaped profile and therefore ensure that it does not obstruct the top piece 9 when it is being mounted on the base piece. In order to simplify the mounting of the top piece on the first fixing profile, said first fixing profile 14 is provided with a rounded top end 17. This makes mounting of the top piece easier. As shown in Figures 1, 2 and 4, the top piece 8, 9 is preferably substantially semi-circular, so that sharp edges are avoided. Other shapes such as oval or conical are, of course, also possible. The base piece is preferably made of metal, with the result that it is of a sturdy construction, while the top piece is made of one of the materials wood, plastic or glass. The glass or plastic can be transparent or coloured, which gives the designer a wide range of possibilities.
