Description

Summary of the Invention

The present invention relates to a device and a method for the uniform application of pasty mass or a similar material, in particular tile adhesive or mortar.

The device and the associated method are used in particular for flat workpieces such as tiles, tile-like workpieces or other flat floor coverings. In particular, the laying of large-format tiles is often difficult because the tiles are not uniformly formed and sometimes have a curvature that sometimes accounts for a difference of 8.5 mm from the center of the tile to the corner of it. For the sake of simplicity, the invention is described below in connection with tiles, but it can also be used for other ceramic, stone, glass, wood, plastic and/or other slab-shaped floor coverings to be installed on walls, floors and/or ceilings can be attached.

Tiles are usually laid using a thin-bed method, with the adhesive being applied manually using a notched trowel to the substrate to be tiled using the floating method, to the back of the tile using the buttering method, or to the floor and the tile using the buttering-floating method is raised. The latter is used for large format tiles. The manual application of the tile adhesive results in an uneven distribution of the tile adhesive. This means that there is often a lot of adhesive in the edge area, while relatively little adhesive can be found in the middle of the tile. The result of this unequal distribution is that cavities form in some cases, which are undesirable because, in addition to possible hollow sounds, they can in some cases lead to stresses within the tile, which are reflected in cracks or other damage to the covering. Such deficiencies in the laying can only be remedied by dismantling the entire construction or by subsequently filling the cavities by injection, which involves a great deal of effort and high costs. The aim is therefore to minimize or even avoid cavities. In addition, the manual methods of applying adhesive to the tiles are tedious and time consuming.

Some devices for coating tiles are known from the prior art, but these are mostly not practicable for daily use at different construction sites, since they are too bulky and/or can only be used for floor coverings. An example of this is the device DE 20 2006 016 922 U1 with which adhesive material, such as glue, is applied to the tiles by means of a nozzle arrangement. Another example is the DE 60 2004 001 380 T2 in which an adhesive applicator is shown consisting of a rectangular housing which is open at its bottom and thus the material placed in the housing, such as the adhesive, can be spread on the floor by a person dragging the housing over the floor. In the DE3726841A1 also describes a device for coating a variety of tiles with mortar. The tiles are transported under a container filled with mortar and coated using a transport mechanism. Another distribution device is in the WO 2020/030658A1 described, which consists of a base plate and guide elements arranged thereon, the latter having a base area.

The object of the present invention is therefore to provide a device and a method with which a uniform application of pasty mass to tiles or similar workpieces is possible in a simple manner and which is designed to be handy so that it can be easily moved from one construction site to the next can be transported. Furthermore, the invention should make it possible to coat different flat workpieces, such as tiles, tile-like workpieces or other flat floor coverings, and to apply different thicknesses of pasty mass or a similar material to them. In addition, the permanent use of a suction cup when applying glue or similar materials to the flat workpieces should be made possible.

The present invention therefore relates to a device for the uniform application of pasty mass, in particular adhesive, to workpieces, comprising a base frame, at least two slide rails arranged parallel to one another and a rake, the base frame being in the shape of a rectangle and having legs in the corner areas, characterized in that the at least two slide rails are movably arranged within a guide element which is arranged transversely to the longitudinal frame of the base frame and the slide rails, and wherein the slide rails each have a height-adjustable guide plate, which is followed by a rake. The workpiece is preferably a tile.

The base frame and/or the legs are preferably made of square aluminum tubes. Furthermore, the base frame can be designed foldable, preferably with the legs are arranged on the base frame by means of movable corner connectors.

In one aspect, the at least one guide element has a guide profile, with the guide element preferably being T-slot profile rails. In a preferred embodiment, two guide elements are also arranged on a longitudinal rail of the base frame.

In a further embodiment, a distance (AB) of 2 cm to 80 cm, preferably 10 cm to 50 cm, can be formed between the guide elements of the two slide rails.

In one aspect of the invention, the slide rails can be designed as L-profiles and can extend over the entire length of the base frame and/or beyond. In a preferred embodiment, one leg of the L-profile of the slide rail points to the inside of the base frame and the other leg of the base frame is directed upwards. The distance between the two slide rails can also preferably be continuously adjustable by means of displacement within the guide elements. In addition, the length of the slide rails is between 50 cm and 400 cm, preferably between 100 cm and 200 cm, particularly preferably between 120 cm and 150 cm.

In a further embodiment, the slide rails have at least one protective element over the entire length, which is particularly preferably a polyamide rod. The protective element is preferably positioned in the corner area of the slide rails and the slide rail has a longer leg length than the width of the protective element.

A further aspect includes the attachment of the respective guide plate, which is placed on a leg of the respective slide rail. The baffle plate is preferably designed to be height-adjustable through the interaction of fastening elements, such as fastening screws, a long nut holder and a long nut, a lock nut handle screw and a corresponding attachment and a handle screw, which enables adaptation to the tile thickness and/or adhesive thickness.

The downstream rake of the device is also preferably held by means of a holder, which is particularly preferably a clamp holder. In the device, the rake preferably extends between the two slide rails lying parallel to one another, the rake particularly preferably being made of flat steel and having wedge-shaped teeth. In addition, the rake can be arranged at a support point of the guide plate, which is adjustable in height in relation to the workpiece and the base frame. In one aspect, the attachment of the rake is directed obliquely to the receiving area, with the rake being particularly preferably arranged on the device in an angle-adjustable manner.

Furthermore, the device can further comprise one or more stabilizing elements, which stabilize the construction of the base frame.

Detailed presentation of the invention

The present invention relates to a device and a method for the uniform application of pasty mass or a similar material to flat workpieces (3).

Hereinafter, as used herein, the article “a” and all derivatives thereof should be understood generally as “one or more” unless otherwise stated or unless the context clearly indicates the singular form.

To the extent that the terms "includes,""has,""possesses," and the like are used in the specification or claims, such terms should be construed as the terms "comprising" or "comprising," ie, not exhaustive, unless is explicitly stated.

Pasty mass or similar materials include, but are not limited to the following list, adhesive, mortar, cement, silicone and/or acrylic, in particular tile adhesive and bonding mortar for attaching tiles to a substrate.

Flat workpieces (3) according to the present invention include not only floor coverings, such as textile and non-textile coverings, but also wall and ceiling coverings. In addition to the textile coverings, such as carpets, the coverings are preferably elastic coverings, hard coverings or mineral coverings. As already indicated in the summary, for the sake of simplicity the invention will be described in the context of tiles. Tiles can be used in a wide variety of designs and materials, for example ceramic tiles, cement tiles, stone tiles, carpet tiles, PVC tiles, but also natural stone slabs, glass slabs, wood and synthetic wood tiles such as parquet and laminate. However, floor or wall tiles made of earthenware, stoneware, terracotta, clinker or fine stoneware are particularly preferably used, since the larger the tiles, the more difficult they are to lay, in particular to bond. Large-format tiles have the problem that they are not uniformly formed, which means that when they are laid, care must be taken that the mortar or adhesive applied compensates for these irregularities in the processing of the tiles in order to prevent cavities under the tiles.

However, the usual manual processes that allow such laying and processing of the tiles, such as the buttering-floating process, are very time-consuming. Simple systems that can be used by every craftsman on the small or large construction site do not exist. Therefore, the present invention is intended to offer a way of applying coverings in one step, regardless of whether they are to be attached to the wall, the floor or the ceiling. For this purpose, the device for evenly applying pasty mass to a flat workpiece (3) is made available.

The device therefore comprises a base frame (25), at least two slide rails (1) and a rake (26), which can each be individually adapted to the respective workpiece (3) or the use.

The base frame (25) is designed to be foldable, like that 7 can be removed, and preferably has the shape of a rectangle, 8th , where the running sides (29) represent the longer sides of the rectangle. The short sides of the rectangle form the beginning (30) and end (31) of the device. The base (25) is preferably made of square aluminum tubes that form the rectangular frame. Further tubes are arranged on the rectangular frame in the area of the corners, which represent the legs or feet (32) of the device. In a preferred embodiment, these are also square aluminum tubes. However, as an alternative to the square aluminum tubes as the base frame (25) and legs (32), any other material can also be used, such as other metals such as steel and/or plastics. For the foldable design, the legs (32) are arranged in movable corner connectors on the rectangular frame so that they can be folded in. Alternatively, the legs or feet (32) can also be arranged on the basic frame with the aid of hinges.

At least one guide element (24) with a guide profile, preferably T-groove profile rails, is arranged on the rectangular frame in the two longitudinal areas. With the help of the guide element with a profile (24), the slide rail (1) can be variably adapted to the different tile widths by guiding the slide rail (1) in the at least one guide element (24). The guide element (24) with a profile is in particular a T-slot profile or T-slot rail. The guide element (24) in the form of the T-slot profile rail (24) is therefore arranged in such a way that it is attached transversely to the longitudinal tube of the rectangular base frame (25). In a preferred embodiment, two T-slot profile rails (24) are attached to a longitudinal rail of the base frame (25), so that the slide rail (1) is held securely. For a secure hold of the slide rail (1), a guide element (24), such as a groove profile rail (24), is located on each of the two longitudinal frame pieces at a distance of between 0% and 40% from the corner connection, particularly preferably between 10% and 30%. away from the corner joint. In order to increase the stability of the guide, however, more than two guide elements (24) can also be arranged. The guide elements (24) are usually made of the same material as the frame (25), but these (24) can also be made of other materials, such as wood, metal and/or plastic. Furthermore, the guide elements (24) can also protrude beyond the width of the base frame (25) to avoid the possibility to offer, despite a base frame (25) with a smaller width, to be able to process flat workpieces (3) with a width greater than the width of the base frame (25).

To allow the use of siphons (27) throughout the use of the device, such as the 10 can be removed, the guide elements (24) attached to the device are not designed to be continuous from one longitudinal side of the base frame (25) to the other side, see for example 1 , 2 , 6 , 8-10 . If the guide elements (24) of the respective slide rails (1', 1") are arranged on the base frame (25) in such a way that they oppose each other, as shown in Fig. 1 , 2 , 6 , 8-10 can be removed, the guide elements (24) are attached at a distance (AB) of 2 cm to 80 cm, preferably 10 cm to 50 cm, from one another. Alternatively, the guide elements (24) of the respective slide rails (1) can also be arranged offset to one another, but it should be noted here that there is a recess in the central surface area of the base frame (25), which allows a suction lifter (27) together with a flat workpiece (3) to be conveyed from the beginning area (30) to the end area (31). In order to further simplify such a transport of the workpiece (3) together with the suction lifter (27), it can be provided that the guide elements (24) or other elements space the slide rails (1) from the base frame (25), ie the distance between the slide rails ( 1) and the base frame (25). Due to the larger distance between the slide rails (1) and the base frame (25), in particular the crossbar of the base frame (25) in the beginning and end area (30, 31), it is already possible to lift the suction cup (27) or the workpiece (3) together with the siphon, directly into the device without having to remove the siphon (27). This spacing can be done using the guide elements (24) themselves, by having a certain height, or using additional elements on which the guide elements (24) are placed in order to increase their attachment area compared to the base frame (25). The spacing between the base frame (25) and the arrangement of the slide rail (1) is preferably between 1 mm and 300 mm, particularly preferably between 10 mm and 100 mm.

The slide rails (1), which allow the flat workpieces (3), in particular tiles or a similar object, to be guided, are arranged parallel to one another, their arrangement preferably corresponding to the longitudinal direction of the base frame (25). In each case one slide rail (1') is arranged in the area of a first longitudinal side of the base frame (25) and the other slide rail (1") is arranged on the opposite longitudinal side of the base frame (25). Although two slide rails (1) are mentioned, it can also be several rails that are fastened one behind the other and result in a long slide rail (1) The slide rails (1) can be made of any material, with metal, plastic or wood, in particular aluminum, being suitable for the training Although the slide rails (1) are referred to as rails and described as L-profiles, the slide rails (1) can also be angle metals or other suitable elements that enable flat workpieces (3), such as tiles, to be guided The slide rails (1) extend over the entire length of the base frame (25) and in some cases can also protrude beyond the base frame (25).

In a preferred embodiment, like that 1-10 it can be seen that two slide rails (1) are used in the form of an L-profile made of aluminum, with one leg of the profile pointing towards the inside of the base frame and the other leg of the base frame (1) pointing upwards, such as, for example the 4 can be seen. With the slide rails (1), which are designed in the form of an angle profile, the workpiece (3) or the upper side of the workpiece (wearing layer) is placed on one of the two angle sides and the other angle side of the slide rails (1) protrudes from the base frame ( 25) high. Consequently, the workpiece (3) should be laterally delimited by the two slide rails (1).

The distance between the two slide rails (1) is continuously adjustable so that it can be adjusted to different widths of the flat workpieces (3), such as tiles. The slide rails (1) are movably arranged on the at least one guide element (24) with the aid of connecting elements such as connecting screws. The guide element (24) is arranged transversely to the slide rails (1), so that the latter can change its position when moving within the guide profile of the guide element. When the guide element (24) is designed as a T-slot profile, the slide rails (1) slide within the T-slot profile, whereby the distance between the two slide rails (1) can be changed, such as, for example 9 and 10 can be removed. In order to obtain the most stable possible handling of the device, although it consists only of a base frame (25), one slide rail (1) is connected to at least two guide elements (24), as described above. Alternatively, however, it can also be provided that only one slide rail (1) is movably arranged on the respective guide elements (24) and the other on one longitudinal edge of the base frame (25) fixed. Consequently, a distance adjustment transverse to the longitudinal direction of the guide elements (24) would only be possible with the aid of a slide rail (1).

In order to avoid or reduce unwanted movement of the slide rails (1), the slide rails (1) can be locked in relation to one another. In one embodiment, this is achieved mechanically, for example by fixing the slide rails (1) to one another or by fixing one slide rail (1) to the base frame (25) using screws, clamping devices, catches, bolts and/or tensioning devices. The device is used for tiles or similar workpieces (3) of different sizes, so stepless locking is advantageous in order to enable the most precise adjustment possible. The slide rails (1) have different lengths depending on the tiles or workpieces (5) to be processed. However, the length of the guide rails (1) is usually between 50 cm and 400 cm, preferably between 100 cm and 200 cm, particularly preferably between 120 cm and 150 cm.

In order to prevent or reduce damage to the flat workpieces (3), such as tiles, at least one protective element (6) is preferably arranged over the entire length of the slide rail (1), which protects the surface of the flat workpieces (3). . Tiles usually have a layer of glaze on the top, which should not be damaged. The upper side of the workpiece (3), which is also referred to as the running surface, means in particular the layer that forms the upper side and is visible after the workpiece (3) has been laid. Due to the fact that the underside of the flat workpieces (3), such as tiles, is directed upwards within the device in order to be able to apply glue or similar materials on the underside, the top is with the wear layer, which in some cases the glaze has, in direct contact with the slide rail (1), as this down, i.e. to the base frame (25) points. In addition to avoiding or reducing damage, the at least one protective element is intended to improve the ability of the workpieces (3) to slide within the device. Plastic, textile fabric, ceramic or leather, for example, can be used as the protective element (6). A polyamide rod as a protective element (6) has proven to be particularly preferred. In order not to increase the running resistance unnecessarily, the protective element (6), such as the polyamide rod, preferably has a smaller width than the leg of the slide rail (1) on which the workpiece (3) rests. The rod is preferably a round polyamide profile, which is arranged in the corner area of the slide rails. However, the protective element (6) is designed in such a way that the leg of the slide rail (1) has a longer leg length than the protective element (6), such as the round polyamide profile. Consequently, the workpiece (3) rests on the protective element (6) and is at a distance from the adjacent leg of the slide rail (1), i.e. the leg that is directed towards the inside of the base frame.

In a further aspect of the present invention, the device also has at least one height-adjustable guide plate (2) per slide rail (1). This baffle (2) is placed on the leg of the slide rail (1), which points upwards away from the base frame (25). Consequently, one leg of the sliding element (1) also serves as a guide for the guide plate (2). The guide plate (2) is located relatively centrally in relation to the slide rails (1) and the base frame (25) and serves as a receiving area (5) for the adhesive or similar materials. The task of the guide plate (2) is to facilitate the application of the pasty mass to the workpiece (3), such as the tile, and to prevent the mass from coming between the slide rail and the tile. When the pasty mass is applied, it is applied to the workpiece (3) using a trowel or spatula. This often results in a few heaps of pasty mass. The guide plate (2) should now serve to keep the pasty mass in a certain area on the workpiece (3). This area is preferably an area that is relatively centrally located in relation to the length of the respective slide rail (1). In principle, however, the entire area, which extends over the entire length from a starting area to the end area, could have a corresponding guide plate. Usually, however, both slide rails (1) running parallel to one another have the same length and are parallel to one another in such a way that their starting areas and end areas correspond. Therefore, the guide plate (2) of both slide rails (1) can be found in the same section area, namely an opposite area. The starting area of the slide rails (1) makes up an area of up to 50%, preferably up to 40%, particularly preferably 30% of the total length of the slide rails (1), with an open end of the slide rails (1) each having a start and the opposite open end marks the end of the guide rail (1). The middle area of the slide rails (1) is preferably an area that is between 10% and 40%, preferably between 20% and 30%, particularly preferably between 25% and 30% in relation to the length of the slide rails (1).

The guide plate (2) is designed in such a way that on the side, on the workpiece (3), such as the tile, it is at a distance from the workpiece (9) or the contact area between the slide rail and the tile (7). The guide plate (2) can be adjusted in height by an interaction of fastening elements, such as fastening screws (11), a long nut holder (10) and a long nut (12), a counter nut handle screw (14) and a corresponding fastening (16) and a handle screw (17). educated. Plain bearings or similar can also be used to adjust the height. When the handle screw (17) is actuated, the guide plate (2) can be moved towards or away from the base (25), whereby an adjustment to the tile thickness or adhesive thickness takes place.

On one side of the guide plate (2), which corresponds to the end area (31) of the device, there is also a holder (19) for a rake (26), which preferably consists of a clamp holder which holds the rake (26) in a support point ( 19) holds. Due to the clamping bracket, the rake (26) can be exchanged as required in order to be able to serve as many areas of application and types of workpieces as possible. In some cases, however, it can also be provided that instead of or in addition to the clamp mounting of the rake (26), the exchangeability is ensured by any known detachable connection to the slide rails (1) and/or to the base frame (25). These may be known connections such as but not limited to the following detachable connections which can be separated and reconnected without destroying the connected parts and the connecting element, these include screw connections, clamp connections, Velcro connections and/or magnetic connections. The rake (26) is used to distribute the pasty mass on the workpiece (3) and wipe off any excess. The rake (26) is arranged in relation to the slide rails (1) in such a way that it is arranged between the two slide rails (1) and spans the entire area between them. The rake (26) can have different shapes and can include, for example, a squeegee or an element with a similar function and/or a toothed spatula. These can have different shapes, such as triangular teeth, triangular pointed teeth, rectangular teeth and/or round teeth, and also differ in the size and spacing of the teeth. In a preferred embodiment, the rake (26) consists preferably of flat steel and particularly preferably has wedge-shaped teeth.

Due to the fact that the rake (26) is arranged at a support point (20) of the baffle (2), this, like the baffle (2), is adjustable in height in relation to the workpiece (3), such as the tile, and the base frame (25) arranged. The advantage of such a height adjustment is that the rake (26) can be adjusted to the thickness and height of the tiles and to the amount of pasty material applied. Such height adjustability

The rake (26) is preferably arranged on the device in such a way that it is directed at an angle to the receiving area. The angle at which the rake (26) is arranged on the device is fixed and is preferably 67 degrees. In an alternative embodiment, an angle adjustment can be provided, which allows the angle to the receiving area (5) to be varied, as a result of which the application of the pasty material can be made easier and more uniform. For this purpose, the rake (26) can be arranged pivotably on a bracket.

In principle, the adjustment of the slide rails (1) to one another, as well as the height of the guide plates (2) and/or the angle adjustment of the rake (26), can also be done electrically. A corresponding drive can take place by means of a motor, which is driven, for example, by electric current, or with an accumulator providing the required current. In the case of an electrical setting, a setting using application software (app) on the device itself (internal) or using an external device such as a smartphone, tablet, laptop and/or computer is also possible. For this purpose, the device has an internal or external computer that can record, forward and/or send the data using wired or wireless transmission options. Examples of wireless transmission connections include Wireless-Lan, i.e. wireless local area networks, or mobile radio, such as Long Term Evolution (LTE), 5G, (Universal Mobile Telecommunications System) UMTS and/or Global System for Mobile Communications (GSM). For the data transmission method, the device has appropriate connections and units that enable such a transmission. Such connectors and devices include, but are not limited to, one or more network connectors, such as an RJ-45 jack, BNC connector, fiber optic connector, modem connector, ISDN card connector, logical network interfaces, software, and/or or wireless network interfaces.

In one aspect of the invention, the device can comprise one or more stabilizing elements (30) which, for example, prevent the base frame (25) from collapsing during use of the device and/or the construction stabilize. In addition to connecting screws, clamps or similar elements, the corresponding stabilizing elements (30) can also be rails or tubes, preferably square tubes made of aluminum. These are preferably arranged on the outer sides of the legs (32), ie the sides pointing away from the beginning and end areas (30, 31), and allow the legs (32) to deflect as much as possible.

However, the slide rails (1), guide elements (2), base frame (25), guide plate (2) and/or the rake (26) can also be partially fixed to one another. This means that their connection to each other can only be separated by destroying at least one component or auxiliary joining parts, such as rivets. In order to be able to ensure a simple exchange of the components or parts and thus also to achieve a simple dismantling and assembly of the device, the individual components or parts are, however, preferably detachably connected to one another. In principle, however, it can also be provided that only certain components are detachably connected to one another and others have a fixed connection to one another.

The present invention also relates to a method for uniformly applying a pasty mass to a flat workpiece (3) using the device described above. For this purpose, the base frame (25) is first set up by bringing the legs (32) into the correct position and, if necessary, holding the stabilizing elements (30) in a fixed position. The slide rails (1) are then moved within the guide elements (24) so that the corresponding workpiece (3) can be arranged between the slide rails (1', 1''). If the distance between the slide rails (1', 1'') corresponds to the width of the workpiece (3), then the guide plate (2) is adapted to the thickness of the workpiece (3). Adjusted. The height adjustment (4) is used for this. The respective guide plate (2) can thus be adjusted in height to workpieces (3) of different thicknesses, in particular by actuating the grip screw (17). By turning the handle screw (17), a long nut (12) is moved within a thread (13) and the guide plate (2) is thus moved in height relative to the slide rail (1). In one embodiment, the device can also be adapted to the workpiece (3) electrically, preferably also via app control by an external device.

When the device has been prepared for the workpiece, the flat workpiece (3), which is preferably a tile, is placed between the two slide rails (1) with the top of the workpiece (3) facing down. The upper side of the workpiece (3), which has the glaze layer or top layer of the workpieces (3), is referred to as the "down" laying direction. The workpiece (3) then lies between the slide rails (1) on the protective element (6). The distance between the two slide rails (1) and/or the guide plates (2) can also be readjusted after the workpiece (3) has been inserted.

The workpiece (3) is inserted in the starting area (30), which makes up up to 50%, preferably up to 40%, particularly preferably up to 30% of the total length of the slide rail (1) or the base frame (25). The starting area (30) or also the receiving area is characterized in that the rake (26) is located at its end. Behind the rake (26) is spoken of the end (31). The workpiece (3) can be placed in the device immediately after it has been placed in the device in such a way that pasty mass, adhesive or similar materials can be applied. In some cases, however, it may be necessary for the workpiece (3) to be pushed into the area of the guide plate (2) or in contact by manually pushing the workpiece (3) or conveying the workpiece (3), for example by a conveyor belt is brought with the rake (26). Seen from the starting area (3), there is a guide plate (2) on the slide rails in front of the rake (26), the area between the two opposing guide plates (2) being the receiving area (5) for the pasty mass, the adhesive or other materials. The pasty mass or the adhesive can be applied to the workpiece (3) in the receiving area (5) without it flowing from the workpiece (3) and being held in the area. The application can be done using suitable tools such as a trowel or spatula. After the application of the pasty mass, which is applied, for example, in small heaps to the workpiece (3), the workpiece (5) is pushed under the rake (26). As already described above, the workpiece can also be pushed through manually below the rake (26) into the end area (31) or by automatically guiding the workpiece (3) by means of a conveyor belt. As a result, the paste-like material is evenly distributed on the workpiece (3), whereby irregularities in some workpieces (3), such as large-format tiles, are evened out.

These and other embodiments of the present invention are disclosed in, and are encompassed by, the specification and examples. The features mentioned in the above description and in the claims can also be combined in any selection and the combinations of features that make sense within the scope of the invention are to be regarded as disclosed. Additional literature on known materials, methods and uses that can be used in accordance with the present invention can be retrieved from public libraries and databases, for example using electronic devices. A more complete understanding of the invention can be obtained by reference to the figures and examples, which are provided for purposes of illustration and are not intended to limit the scope of the invention.
