The present invention relates to the passing of cables through a frame.

The invention relates particularly to a method for arranging a cable bushing in a frame of a door or a window for the purpose of passing a cable from an inner side to an outer side of the door or the window, which frame comprises a number of frame beams, each with a thickness and, perpendicular thereto, a width, wherein the width of the frame beam extends from the inner side to the outer side of the door or the window, and comprises a rebate arranged in each frame beam for the purpose of receiving the window or the door, which rebate has a rebate depth and, perpendicular thereto, a rebate width, and wherein the rebate depth extends in the direction of the width of the frame beam.

When a cable is used in an environment which has no terminal therefor, it is common for such a cable to be carried to another space which does comprise such a terminal. This is usually done by passing the cable through a door or window passage of said other space.

Common problems when using a cable from an inner side to an outer side of a door or window, and vice versa, are damage to such a cable and an inability to close a door or window during use. A cable can for instance become damaged by a door or window closing thereon, and can for instance also be damaged by persons and other objects passing the door or the window. A door or window can usually not be closed when a cable has been carried through the door or window passage, since this is for instance prevented by the size of the cable. As a result, the space which is generally closed by the door or the window in question will for instance be accessible to unauthorized persons, and the space will for instance also be left unprotected against weather influences and temperature differences, as well as vermin, dust particles or other types of pollution from outside this space.

It is an object of the invention to obviate the above stated problems, i.e. to provide a method, system and product which enable passage of a cable through a door or window without damaging the cable, while the door or the window can also be closed in the usual manner.

According to a first aspect thereof, the invention provides for this purpose a method of the type stated in the preamble, with the special feature that arranged in one of the frame beams, in the direction of the width of the frame beam on the side of the rebate, is a channel-like passage opening which has a bottom surface and two side surfaces and which extends from the inner side to the outer side, and which passage opening has in the direction of the thickness of the frame beam a depth which is a distance D greater than the rebate width, such that the passage opening intersects with the plane of the rebate which forms the rebate depth, whereby a cable with a diameter of a maximum of D can be arranged in the passage opening against the bottom surface and the door or the window can be closed without coming into contact with the cable, and wherein a releasable insert is arranged in the passage opening, which insert has a shape which is substantially identical to the shape of the passage opening formed in the frame beam.

The advantage of the described method according to the invention is that a cable can be carried through a frame of a door or window in temporary manner, i.e. non-permanent manner, while the door or the window can herein be closed without being obstructed by the cable or damaging the cable. This method likewise provides a simple yet effective manner of introducing and removing the cable by means of the above stated releasable insert. A particular advantage of the method is that arranging of additional terminals, such as wall sockets, in the environment of use of the cable, such as outdoors, can be avoided. With this, the present invention therefore obviates the above stated problems in passing of a cable from the inner side to the outer side, and vice versa, of a door or window.

The invention is a system which is versatile and easy to use in the construction industry. It is noted that the present invention is suitable for use in door and window frames, as well as sills, shutters, covers, skylights, roof hatches, wall hatches and similar closures for openings, both for hinged and sliding embodiments thereof. The invention is likewise particularly suitable for aluminium, steel and plastic frames. The field of application of the invention is not limited to buildings either, and also extends to vehicles, such as trucks, camper vans and cars, containers, construction power distribution boxes, underground spaces, safes, server areas, data centers, and other applications wherein a closure for an opening is used in combination with cables, or other objects of similar size. It is noted that the invention can be used both in indoor and outdoor situations.

Before the passage opening is arranged in the frame beam, an opening is preferably first made in the frame beam, preferably by means of milling or sawing, having a shape which corresponds to the passage opening and is larger than the passage opening, after which a preferably fixed border frame, which forms a border of the passage opening, is arranged in the opening. Such a border frame is preferably manufactured from a wear-resistant material, such as a hard plastic. Other materials can also be envisaged, which can for instance be chosen on the basis of aesthetic, economic, environment-specific or environmentally friendly considerations. In a particular embodiment the fixed border frame can consist of a material, such as resin or a powder coating, arranged at the location of the opening.

The insert preferably comprises a housing in which a filler piece is received, wherein the filler piece is preferably manufactured from flexible material which can flexibly enclose a cable lying against the bottom surface of the passage opening, and wherein the housing preferably has a shape such that it surrounds the filler piece at least along the outer sides of the passage opening.

The housing is preferably manufactured from wear-resistant material, such as a hard plastic. Other materials can also be envisaged, which can for instance be chosen on the basis of aesthetic, economic, environment-specific or environmentally friendly considerations. In a particular embodiment the housing can consist of a material, such as resin or a powder coating, arranged on the filler piece along at least some or along all outer sides of the passage opening. The filler piece is preferably manufactured from flexible, i.e. deformable, material, such as a foam material or rubber, and similar materials known to the skilled person, so as to be able to accommodate cables with different diameters while a reliable enclosure of the cable is brought about. The filler piece preferably comprises a brush part comprising a plurality of fibres, which brush part can preferably flexibly enclose a cable lying against the bottom surface of the passage opening. It is also noted that such a filler piece preferably closes the passage opening in substantially air and moisture-tight manner when no cable has been carried through the cable bushing system. It is likewise possible to place a draught strip on the insert in order to close any gaps.

One or more recesses for passage of a cable which preferably lies against the bottom surface of the passage opening are preferably arranged in the insert, at least in the housing thereof, on the side facing toward the bottom surface of the passage opening. Recesses for passage of a cable which preferably lies against the bottom surface of the passage opening are preferably arranged in both the housing and the filler piece of the insert.

The passage opening is preferably wholly open toward the door or window side.

The invention also relates to a cable bushing system for a frame of a door or a window for the purpose of passing a cable from an inner side to an outer side of the door or the window. The cable bushing system preferably comprises a fixed border frame forming a channel-like passage opening with a bottom surface and two side surfaces, which passage opening is preferably wholly open toward the side remote from the bottom surface, and a releasable insert which can be arranged in the passage opening, which insert has a shape which is substantially identical to the shape of the passage opening.

The advantage of the described cable bushing system according to the invention is that a cable can be carried through a frame of a door or window in temporary manner, i.e. non-permanent manner, while the door or the window can herein be closed without being obstructed by the cable or damaging the cable. The system likewise provides a simple yet effective manner of introducing and removing the cable by means of the above stated releasable insert. With this, the present invention therefore obviates the above stated problems in passing of a cable from the inner side to the outer side, and vice versa, of a door or window.

The side surfaces of the fixed border frame preferably have a shape which preferably corresponds to the cross-section of a frame beam with a rebate arranged therein. Such a border frame is preferably manufactured from a wear-resistant material, such as a hard plastic. Other materials can also be envisaged, which can for instance be chosen on the basis of aesthetic, economic, environment-specific or environmentally friendly considerations. In a particular embodiment the fixed border frame can consist of a material, such as resin or a powder coating, arranged at the location of the opening.

The insert preferably comprises a housing in which a filler piece is received, wherein the filler piece is manufactured from flexible material which can flexibly enclose a cable which preferably lies against the bottom surface of the passage opening, and wherein the housing preferably has a shape such that it surrounds the filler piece at least along the outer sides of the passage opening.

More preferably, the filler piece also forms an air and moisture-tight closure of the passage opening. The filler piece is preferably manufactured from flexible, i.e. deformable, material, such as a foam material or rubber, and similar materials known to the skilled person, so as to be able to accommodate cables with different diameters while a reliable enclosure of the cable is brought about.

One or more recesses for passage of a cable lying against the bottom surface of the passage opening are preferably arranged in the insert, at least in the housing thereof, on the side facing toward the bottom surface of the passage opening. Such recesses are preferably arranged with such dimensions that common cable diameters, such as power cables or high-voltage power cables, can be accommodated. It is also possible to envisage dimensions which accommodate a different kind of cable, cord or hose. The fixed border frame and the insert are preferably provided with mutually co-acting guide means which enable the insert to be removed from the fixed border frame, preferably in a direction with a component perpendicularly of the bottom surface of the fixed border frame, but which preferably prevent movement of the insert relative to the fixed border frame in other directions. These guide means can be arranged or form a whole with the fixed border frame. The guide means can preferably likewise form part of the frame in which the insert is placed. The guide means preferably ensure that the insert cannot be removed when the door or the window is closed, in order to prevent break-ins and undesired falling out of the insert.

The insert is preferably mounted releasably in the passage opening by means of a snap connection. Such a snap connection can be realized in ways known to the skilled person. A snap connection is preferably formed on one or more parts of the insert or the fixed border frame to be engaged by the user. The insert is more preferably provided with one or more elements, to be pressed by the user, for uncoupling the insert from the border frame.

The invention further relates to a frame beam for a frame of a door or a window provided with a cable bushing for the purpose of passing a cable from an inner side to an outer side of the door or the window, which frame beam has a thickness and, perpendicular thereto, a width, wherein the width of the frame beam extends from the inner side to the outer side of the door or the window, and a rebate arranged in each frame beam for the purpose of receiving the window or the door, which rebate has a rebate depth and, perpendicular thereto, a rebate width, wherein the rebate depth extends in the direction of the width of the frame beam. Preferably arranged in one of the frame beams, in the direction of the width of the frame beam on the side of the rebate, and preferably by means of milling or sawing, is a channel-like passage opening which has a bottom surface and two side surfaces and which extends from the inner side to the outer side, and which passage opening has in the direction of the thickness of the frame beam a depth which is a distance D greater than the rebate width, such that the passage opening intersects with the plane of the rebate which forms the rebate depth, whereby a cable with a diameter of a maximum of D can be arranged in the passage opening against the bottom surface and the door or the window can be closed without coming into contact with the cable, and wherein a releasable insert is arranged in the passage opening, which insert has a shape which is substantially identical to the shape of the passage opening formed in the frame beam.

The advantage of the described frame beam according to the invention is that a cable can be carried through a frame of a door or window in temporary manner, i.e. non-permanent manner, while the door or the window can herein be closed without being obstructed by the cable or damaging the cable. The frame beam likewise provides a simple yet effective manner of introducing and removing the cable by means of the above stated releasable insert. With this, the present invention therefore obviates the above stated problems in passing of a cable from the inner side to the outer side, and vice versa, of a door or window.

The invention also relates to an insert for use in a method for arranging a cable bushing in a frame of a door or a window for the purpose of passing a cable from an inner side to an outer side of the door or the window. The insert preferably comprises at least a recess for enclosing a cable lying against a bottom surface of a passage opening.
