Description

The invention relates to a sill assembly. The sill assembly may for example be used for a window or door.
A known sill assembly comprises a sill and for example two plinth blocks that are attached thereto, for example at two opposing end zones thereof, wherein window or door frame elements may be attached to the plinth blocks. The plinth blocks may for example be attached to the sill using known attachment means, such as a screw or bolt. The sill may for example be formed by a hollow profile made of plastic or metal, or the sill may be a solid plastic sill.
WO00/58589A2 discloses a sill assembly according to the preamble of appended claim 1.
It is an object of the invention to improve the known sill assembly.
The sill assembly according to the invention comprises a sill and at least one plinth block, wherein said sill and said plinth block comprise mutually cooperating connecting means for connecting the at least one plinth block to the sill.
An advantage of the assembly according to the invention is that said at least one plinth block may be connected to the sill in a quick and/or easy way.
By eliminating the use of a screw or bolt a cold bridge that may otherwise be formed by the screw or bolt may be prevented.
The connecting means may provide either a permanent or a releasable connection between the sill and the at least one plinth block. A permanent connection is to be understood as that the plinth block and the sill cannot be disconnected from each other without damaging one or both of the plinth block and the sill. In a releasable connection the sill and at least one plinth block can be disconnected and reconnected to each other.
Optionally an adhesive such as glue may be applied to abutting surfaces of the plinth block and sill, in order to enhance the connection therebetween.
In another embodiment of the sill assembly according to the invention said connecting means are integrally formed with the sill and the at least one plinth block, respectively.
Integrally formed connecting means may provide a strong and/or easy and/or quick connection of the sill and the plinth block to each other.
Additionally or alternatively, integrally formed connecting means may reduce susceptibility of the plinth block and/or the sill to damage due to moisture.
Furthermore, integrally formed connecting means may provide a good and/or watertight and/or airtight sealing between the plinth block and the sill.
With the known assembly the position and/or location of the plinth block with respect to the sill may not be accurately defined, such that it consumes more time to correctly connect the plinth block to the seal and/or more positioning errors may be made.
In an advantageous embodiment of the sill assembly according to the invention said connecting means are arranged such that the at least one plinth block connects to the sill at a predetermined location and/or orientation, at least in a direction orthogonal to a longitudinal direction of the sill.
An advantage of this embodiment is that the plinth block is connected to the seal at a correct location and/or orientation, which may increase the speed of connecting the plinth block to the sill and/or may reduce the positioning errors.
Said location and/or orientation may be defined by the connecting means which may be provided on the sill and the plinth block at a desired location and/or orientation. With use of the connecting means the plinth block may be connected to the sill in only one possible way, such that the location and/or orientation thereof is defined by the location and/or orientation of the connecting means.
The sill of the sill assembly according to the invention comprises a basic sill part and a stop block for a moveable door or window, wherein said basic sill part and said stop block comprise mutually cooperating connecting means for connecting the stop block to the basic sill part.
An advantage of this embodiment is that the basic sill part may have a similar shape and/or size for many applications, wherein the stop block may be adapted to a specific application.
According to the invention the sill is made of a solid plastic material, and said sill is made by machining and/or milling. In such a case a (pressed) plastic starting material, for example in the form of a plate or beam, is provided that is machined and/or milled into the shape of a sill. However, if the sill is made of one integral piece a lot of material is machined away, which results in a lot of waste and/or higher production costs and/or increased production time. Furthermore, a relatively thick plastic starting material may be required, which is relatively expensive in comparison to separate, multiple starting material parts that together have a same thickness. If said sill is made of a basic sill part and a stop block, said sill parts may be made separately of separate starting materials, thereby creating less waste and/or lower production costs and/or less production time.
The stop block may be connected to the basic sill part after installation of the basic sill part, so that, if the sill is to be installed in a window or door frame, the basic sill part may be installed in the frame together with window glazing or a door while the stop block is to be installed later. This may leave room for wiring or cables, for example for providing electricity from indoors to outdoors, which is often desired by builders and/or construction workers.
The basic sill part may be made as one continuous length of material, from which continuous length a basic sill part with a desired length may be cut off.
In yet another embodiment of the sill assembly according to the invention the connecting means of the basic sill part are arranged for connecting with both the stop block and the plinth block.
An advantage of this embodiment is that said basic sill part my require only one type of connecting means to which both the stop block(s) and the plinth block(s) may connect, which results in a relatively simple basic sill part that may in particular be suitable for different applications.
The basic sill part of this embodiment may provide the user with flexibility to choose the connection location of the stop block and/or the plinth block.
The connecting means may be arranged as a substantially continuous type of connection means extending over at least a large part of the length of the basic sill part. In such an embodiment the stop block and the plinth block may be connected to the basic sill part at any location along the length thereof. The plinth block and stop block may in particular be connected to the basic sill part adjacent to each other, optionally with a sealing therebetween.
The connecting means of the basic sill part for connecting to the plinth block may optionally be arranged at a different location on the basic sill part than the connecting means of the basic sill part for connecting to the stop block.
The connecting means of the basic sill part for connecting to the plinth block and the connecting means of the basic sill part for connecting to the stop block may be similar, in particular identical.
The connecting means of the plinth block and the stop block may be similar, in particular identical.
In the sill assembly according to the invention the mutually cooperating connecting means comprise a recess and a projection, wherein the recess is arranged to receive the projection, wherein said projection is arranged as a snap projection.
The recess and the projection may provide a sturdy way of interconnecting the sill assembly. The snap projection may provide a secure way of interconnecting the assembly as well as providing feedback as to whether the sill assembly has been interconnected properly.
In such an embodiment the recess functions as a female connection part and the projection as a male connection part. The sill may comprise one of the recess and the projection, and the plinth block may comprise the other one of the recess and the projection. In particular the basic sill part may comprise one of the recess and the projection, and the plinth block and the stop block may comprise the other one of the recess and the projection.
The snap projection preferably comprises outward extending gripping elements and is preferably arranged to be moved from a normal, spread position to a squeezed position during connection of the sill to the plinth block, or during connection of the basic sill part to the plinth block or stop block, and to move back to its spread position after connection thereof, such that the gripping elements engage to the recess of the other connecting means.
In yet another embodiment of the sill assembly according to the invention the basic sill part comprises a continuous recess or projection extending over substantially the entire length thereof.
An advantage thereof is that the stop block and/or the plinth block, which comprises the other of the recess or projection, may be connected to the basic sill part at any desired location over the length thereof, while the connection position in an orthogonal direction to the length of the basic sill part and/or the orientation is predefined.
As described above, this provides for the opportunity to make one continuous length of basic sill part from which multiple basic sill parts may be cut off.
Preferably the other one of the recess or projection is also a continuous recess or projection extending over substantially the entire length of the plinth block and/or the stop block. The length of the plinth block and/or stop block is defined parallel to the length of the basic sill part when the basic sill part is connected to the plinth block and/or stop block.
According to the invention, the sill is made of a solid plastic material. In yet another embodiment of the sill assembly according to the invention said plinth block is made of a solid plastic material.
A solid plastic material has the advantage that it is rigid without being heavy and prevents a cold bridge. Additionally a solid plastic material may be weather and/or moisture resistant.
Furthermore the solid plastic material may increase the structural rigidity of the connecting means, and allows for a machining or milling operation to produce the connecting means.
The solid plastic material may be chosen from the group comprising polyvinylchoride (PVC) and polyolefines, for example Low Density Polyethylene (LDPE), Linear Low Density Polyethylene (LLDPE), High Molecular Weight Polyethylene (HMWPE) or Ultra High Molecular Weight Polyethylene (UHMWPE).
Both PVC and polyolefines are suitable materials. In particular the polyethylenes as listed can be recycled very well, so that preferably such recycled material is included in the sill and/or plinth blocks. The material is very suitable for use in the "Sustainable building" program in the Netherlands. The recycled material can in an advantageous manner -at last partly- consist of visible particles, which particles preferably have a different colour. Most of the material of the sill and/or plinth blocks may for instance be black, with in it lighter pieces of recycled material, which gives it a natural appearance, when a stone-like appearance is wanted. Alternatively of course a wood pattern could also be realized in a similar manner. The material has a higher ignition temperature than wood: in order to ignite permanent contact with a flame is necessary.
According to the invention, the sill is made by means of machining and/or milling. In yet another embodiment of the sill assembly according to the invention said plinth block is made by means of machining and/or milling.
Machining and/or milling provide the advantage of being versatile so that many different shapes of sill assemblies can be made without having to invest in different moulds. Furthermore machining and/or milling may be cheap and/or quick and/or require little energy.
In particular the basic sill part and the stop block may be made of solid plastic, preferably by machining and/or milling. As described above, when the sill is made of solid plastic by machining or milling, it is advantageous to provide the basic sill part and the stop block in order to decrease waste material and/or productions costs and/or time.
The present invention will now be described by way of example with reference to the accompanying drawings. In the drawings:

In all figures like parts are numbered by like numbers. In different embodiments similar elements are numbered by similar numbers increased by 100.
Figures 1 and 2 show a window and door frame 1. Said frame 1 comprises a basic sill part 2 that extends along a bottom side of the frame 1 in a longitudinal direction. End plinth blocks 3 are connected to both longitudinal end zones of the basic sill part 2. An intermediate plinth block 4 is connected to an intermediate part of the basic sill part 2, in this example to the middle of the basic sill part 2 as seen in the longitudinal direction thereof. The plinth blocks 3, 4 connect to respective posts 5 of the frame 1, which posts 5 extend substantially vertical in use of the frame 1. The posts 5 may be connected to the plinth blocks 3, 4 in a conventional way, for example using screws, bolts or glue. A window stop block 6 is provided between the plinth blocks 3, 4 on one side of the basic sill part 2 as seen in the longitudinal direction thereof and is connected thereto. A door stop block 7 is provided between the plinth blocks 3, 4 on the other side of the basic sill part 2 as seen in the longitudinal direction thereof and is connected thereto. The window stop block 6 and the door stop block 7 are hereby arranged adjacent to the plinth blocks 3, 4, optionally with a sealing provided there between (not shown in figures 1 and 2). As shown in figure 2, in this example the basic sill part 2 comprises a continuous snap projection 8 extending over the entire length thereof, in particular along the upper side thereof. The plinth blocks 3, 4 and stop blocks 6, 7 each comprise a respective recess 9 at there bottom sides for receiving the snap projection 8 of the basic sill part 2. The plinth blocks 3, 4 and stop blocks 6, 7 may be connected to the basic sill part 2 using these mutually cooperating projection 8 and recesses 9. As the position and orientation of the projection 8 and recesses 9 are defined, the position and orientation of the plinth blocks 3, 4 and stop blocks 6, 7 with respect to the basic sill part 2 is defined in a direction orthogonal to the longitudinal direction of the basic sill part 2. The position of the plinth blocks 3, 4 and stop blocks 6, 7 along the length of the basic sill part 2 are suitably chosen, such that these are in their longitudinal position as described above. The recesses 9 of the plinth blocks 3, 4 and stop blocks 6, 7 are in this example also formed as continuous recesses 9 extending over the entire lengths of the respective plinth blocks 3, 4 and stop blocks 6, 7. The length of the plinth blocks 3, 4 and stop blocks 6, 7 is hereby defined parallel to the length of the basic sill part 2. As further shown in figure 2, in this example the basic sill part 2 further comprises a continuous recess 10 extending over the entire length thereof, in particular along the bottom side thereof. Said recess 10 is suitable for connecting to a snap projection 11 of a water bar 12, which water bar 12 may thereby be connected to the bottom of the basic sill part 2 along and side end zone thereof. The snap projection 11 hereby extends along the entire length of the water bar 12, in particular along the upper side thereof.
In the example of figures 1 and 2 a sill assembly of the window and door frame 1 comprises said basic sill part 2, said plinth blocks 3, said stop 6, 7 and said water bar 12.
It is noted however that said sill assembly may comprise any suitable parts and is not limited to this example. In particular it may comprise less or additional parts, which additional parts may be similar or different parts. It is also possible that said basic sill part is formed as one integral sill with said stop blocks 6, 7 and/or said water bar 12, to which sill said plinth blocks may be connected using mutually cooperating connecting means.
In the example of figures 1 and 2 the basic sill part 2, stop blocks 6, 7, plinth blocks 3, 4 and water bar 12 are made of a solid plastics material, for example by machining and/or milling a starting plastic material. The projection 8 and recesses 9 thereof may for example be made by milling. The posts 5 are hollow profiles made of any suitable material.
Figure 3 is a simplified view of the frame 1 of figures 1 and 2 in which the vertical posts are not shown. The adjacent and in particular abutting relationship of the plinth blocks 3, 4 and stop blocks 6, 7 is clearly shown in this figure 3. This figure 3 further shows that the plinth blocks 3, 4 provide a flat upper surface for connecting the vertical posts thereto. Figure 3 further shows that the upper surfaces of the plinth blocks 3, 4 and stop blocks 6, 7 are arranged in the same horizontal plane, i.e. extend at the same height and form one continuous, flat surface.
Figure 4 shows the mutually cooperating connecting means in the form of snap projection 8 of the basic sill part 2 with recesses 9 of plinth blocks 3, 4 and stop blocks 6, 7, and recess 10 of the basic sill part 2 with snap projection 11 of the water bar 12 in more detail. This figure 4 shows that the snap projections 8, 11 comprise outward extending gripping elements 13. When the snap projections 8, 11 are inserted in respective recesses 9, 10, the snap projections 8, 11 are pressed inwards by a relatively small, neck part 15 of the recesses 9, 10 from their normal, spread position as shown in figure 4 into a squeezed position (not shown). After passing the neck part 15 the snap projections 8, 11 move back to their spread position, in which position the gripping elements 13 engage onto engaging surfaces 14 of the recesses 9, 10. A strong connection between the basic sill part 2 with plinth blocks 3, 4, stop blocks 6, 7, and water bar 12 is hereby made.
Figure 5 shows the plinth block 3 that is connected to basic sill part 2 using the mutually cooperating connecting means in the form of recess 9 and projection 8 thereof. The vertical post 5 is to be connected to the plinth block 3 using conventional means as described above. This figure 5 shows that the shape of the upper surface of the plinth block 3 is in this example adapted to and in particular identical to the shape of the lower surface of the post 5. The post 5 is thereby to be fixed to the plinth block 3 in one determined way, in which the mating surfaces of the plinth block 3 and post 5 are aligned.
Figure 6 shows a door 17 which is closed against the stop block 7 of the sill assembly with a stop 16, which stop block 7 is connected to the basic sill part 2 as described above.
Figure 7 shows a window 18, in particular the lower, horizontal frame part thereof, which is closed against the stop block 6 of the sill assembly with a stop 19, which stop block 6 is connected to the basic sill part 2 as described above.
Figure 8 shows the post 5 that is attached to the plinth block 3, which plinth block 3 is connected to the basic sill part 2 as described above.
Figures 9A and 9B show a basic sill part 102 according to a second embodiment. Only the differences with the basic sill part 2 of figures 1 - 8 will be described here. For a further description of the basic sill part 102 the reader is referred to the description of figures 1-8.
The basic sill part 102 comprises a recess 132 along a longitudinal side surface thereof. Said recess 132 is arranged to receive a projection 131 of an extension element 130. The extension element 130 increases the width of the basic sill part 102. The extension element 130 shown in figure 9A has a smaller width than the extension element 130 of figure 9B. As such, the total width of the sill formed by the basic sill part 102 and extension element 130 is smaller for the sill of figure 9A than the sill of figure 9B. This shows that by connecting suitable elements to the basic sill part the dimensions and/or shape of the sill may be suitably chosen.
It is noted that the invention is not limited to the shown embodiments but also extends to variants within the scope of the appended claims.
