DEVICE TO BE USED WHEN MOUNTING FRAMES OR SIMILAR PARTS

Abstract: Mounting a frame into an opening in an interior wall, brick wall, floor, ceiling or similar support is a complicated and time-consuming task. The mounting of a frame depends on the initial positioning and directional adjustment of the parts of the frame occurring in exactly the correct manner. One intention of the present invention is to make possible a rapid and correct placing of parts of a frame that are to be mounted. In this way the task of mounting is made more efficient and the quality of the result is higher, which results in an improved economy during building. The present invention refers to a device (1) to be used when mounting frames or similar parts into a support, with an outer form that makes it possible to place one part of the device into a hole, intended for a fixing device, in a frame. The part of the device that is placed into the hole includes means that demountably fix the device to the support. The outer form of the device further makes it possible to turn the frame round, and/or displace the frame axially along the fixed device.

Description: Device to be used when mounting frames or similar parts The present invention concerns a device to be used when mounting frames or similar parts and a method to be used when mounting frames or similar parts with the said device. The mounting of a frame into an opening in an interior wall, brick wall, floor, ceiling or similar support is a complicated and time-consuming task. Each part of the frame must be separately adjusted both horizontally and vertically relative to the support and relative to each other. At the same time, adjustments may be necessary relative to a door, a window, a hatch-cover or similar constructions, particularly if the door is warped or has a shape that deviates in some other way. The different parts of the frame can also be pre- assembled to a frame construction, which then must be mounted in as a complete unit. Many distances and angles must be measured, checked and adjusted. An erroneous mounting may in the worst case make it necessary to demount all the parts of the frame, move them and remount them. It is normal to make the task of mounting easier by provisionally fixing the frame with one or more nails that are hammered through the frame into the support. This results in the presence of undesired nails or nail-holes in the frame. Complicated devices for the provisional fixing and adjustment of frames prior to mounting have been documented, but these have never made an impact in the market since they do not offer a solution that both makes the task easier and minimises the time required. SE, C2, 507 061 presents a fixing device for the adjustable fixing of a frame into the opening in a wall. Frame is used to denote a door-frame or a similar frame that receives a door leaf, a window, or something similar. The fixing device includes a sheath that is arranged in the frame and a fixing element in the form of a screw that passes through the sheath and anchors the frame and the sheath to the wall. The sheath can be rotated around the screw after mounting. This rotation results in a movement of the frame relative to the sheath and the support. Thus, a precise adjustment of the fitting of the frame can be made after the fixing device has been fixed to the wall through the frame. The frame is provided with pre-drilled holes with an internal thread that corresponds to an external thread of the sheath. Other similar fixing devices are available on the market. Fixing the frame with such devices is currently the most usual method of mounting frames. The precise adjustment that these fixing devices make possible, however, cannot compensate for careless measurement and checking during the initial fixing of the parts of the frame. Once an erroneous mounting has taken place, it is very difficult to remove a fixing device of the type described, to move the part of the frame a small distance and the remount the fixing device in the support. It is often a matter of small movements, and there is a considerable risk that the new mounting must be carried out so close to the old drilled fixing hole that the support cannot offer a reliable structure for fixture. The mounting of the frame thus depends on the first positioning and directional adjustment of the parts of the frame occurring in an exact manner. One intention of the present invention is to make possible a rapid and correct positioning of the parts of the frame that are to be mounted. In this way the task of mounting is made more efficient and the quality of the result is higher, which results in an improved economy during building. This intention is achieved by the device according to the present invention exhibiting the properties and characteristics that are described in claim 1 and by the method according to claim 8. Other properties and characteristics of the invention are made clear by the remaining claims and the description given below, in which an embodiment of the invention is described more closely with reference to fig. 1, which shows the device itself, fig. 2, which shows a cross-section of the device and fig. 3, which shows a situation during the mounting of a door-frame. A further embodiment of the invention is shown in fig. 4 and fig. 5. The embodiment of the device described in the following is adapted to the mounting of frames that are mounted onto a support with fixing devices that make possible a limited adjustment of the fixture when the fixing element has been mounted. The frames are provided with pre-drilled holes that are adapted to the external diameter and other dimensions of the fixing device. The figures show a device 1 for mounting a frame with an extended body that includes a part A for fixing the device, a part B for supporting the door-frame and a part C for receiving/transferring force. The device fixing part A comprises one end of the device 1 and includes a point 2 provided with a shallow thread 3. The point 2 provided with the thread makes it easy to hammer in the device 1 with a blow from a hammer or to screw the device into the support using a rotational motion, and thereby fix it into its working position. Once the task is completed, the device 1 can be removed by pulling it directly from the support, or screwing it out with a rotational motion. A small mark from the point is left in the support after the device has been removed. This mark facilitates the mounting of the fixing device. If the temporary mounting with the aid of the devices has not been correct, it is very easy to dismount the devices and start again, since the mark from the point 2 is small compared to the holes that arise when a fixing device is mounted/dismounted. The final marking is always positioned centrally in the frame holes if the point 2 is centrally arranged on the device. The door-frame supporting part B has the form of a cylinder, forms the central part of the device 1 and has an external diameter 0g that corresponds to the internal diameter 0 j _ j of the pre-drilled holes in the frame. When the device 1 is placed into one of the holes and fixed into the support, the device 1 provides a support for the frame, which can be turned round and displaced axially along the door-frame supporting part B. The force receiving and transferring part C forms the main part of the other end of the device and includes a flat end surface, an impact surface 4, perpendicular to the central axis of the body, constructed to receive hammer blows for driving the device into the support. The driving in action can also occur by a rotational motion which is why the device is provided with a handle section 5. The handle section 5 is knurled in order to provide a large amount of friction. The device 1 is further provided with, in association with the force receiving/ transferring part C, one or several arrangements that make the removal of the device from the support easier. The previously mentioned handle section 5 can be used for gripping with at least one hand in order to transfer rotational/withdrawal forces. As shown in the figure, the arrangement can further include a waist, which forms a withdrawal surface 6, which in turn offers a contact surface for, for example, the nail-drawing side of a hammer, or a hole 7, shown in a cross-sectioned part of the device in fig. 1 , perpendicular to the central axis of the device for the reception of a instrument for transferring torque. The design of the device can, naturally, be freely varied within the framework of the innovative concept. The embodiment of the device 1 shown is cylindrically formed along the complete length of the body construction since it has been manufactured from a cylindrical rod with an external diameter that corresponds with a good fit to the inner diameter of the holes. Moreover, the device is designed to require the minimum possible processing of the original blank. A blank with edges, a rod with a hexagonal cross-section for example, can also form the basis for the production of a device corresponding to the invention according to claim 1. The important point is that the fit between the device and the hole in the frame is sufficiently good to ensure that the device controls the frame in the correct manner. The device fixing part A can include fixing devices that have another appearance and there can be more than one of them. The device fixing part A can also include a material with a good adhesive ability that attaches to the support without directly penetrating the support, for example, tape, glue, an adhesive compound or similar, and which also makes it possible to remove the device without damaging the surface of the support in any way. The device 1 can be made to support the door-frame along its complete length or only partially, with advantage at the end of the device that includes the device fixing part A so that the frame supporting part B is placed close to the support. The rough surface of the handle section 5 can be achieved, in addition to knurling, by other surface treatments, insertion of material or the application of one, or more, layer of material. The force receiving/transferring part C will automatically be easy to grasp if the device is manufactured from a blank with edges and in this case it will not be as necessary to process the actual handle section 5. The furthest end of the device 1 at the force receiving/transferring part C can be constructed in a form that allows it to be attached to a tool wrench, for example, by it having a hexagonal form, without the function of the end with respect to receiving blows being affected. The device 1 can be manufactured with various appearances for the various parts and from various materials. The choice of material is naturally directed by the requirements for impact resistance, tensile strength and other aspects of resistance/strength so that the device will resist the forces to which it is exposed when in use. Different metal materials are those that are most obvious, considering the other tools that are used during building work and considering that the manufacture and costs are to be optimised, but other materials that can be formed to make the device and that satisfy the requirements for strength can be used. The method will be described here with reference to the embodiment of the invention that has been described. The initial situation when a frame is to be mounted is normally the existence of an opening in a support that is to be provided with frames, which in turn are to work together with a door, a window, a hatch-cover, or a similar construction. The method for mounting the frame using the device will firstly be described totally generally. It will then be adapted to the mounting of a door-frame, and finally adapted to the mounting of a window-frame in the form of a fixed frame construction. In general, the method proceeds by the part of the frame (K). which has been formed to the appropriate size and provided with holes (H) for receiving fixing devices designed for the frame, is placed where it is to be mounted. One end of the part of the frame is brought into position relative to the support and the device (1) is placed into that hole that is located closest to this end. The device is fixed to the support by a blow from a hammer or by a screwing motion. The part of the frame is now free to turn round the device and is freely axially displaceable along the body of the device. After this, the position of the other end of the frame is determined so that this part of the frame is positioned horizontally and/or vertically level, after which a further device is placed in another of the holes in this part of the frame and fixed to the support. The part of the frame can now only be moved axially along the devices. When the position of the part of the frame has been determined also in this direction, for example using wedges or fitting blocks, fixing devices are mounted in the rest of the holes in the part of the frame and fixed to the support. After this the devices are demounted and replaced by ordinary fixing devices. If the fixing devices are of the type that makes it possible to carry out a certain adjustment of the attachment of the frame, this is the time to make this final adjustment. If the mounting of the frame refers to a door-frame, the method is the same as that described above with certain additions. The task of mounting usually starts with determining the position of the threshold, and mounting it horizontally level and parallel with the support. After this, the two vertical side frame pieces are arranged according to the procedure described above up until that point at which two devices are fixed through holes in the frame. After this, it is time for the upper horizontal part of the frame, which is thus also guided by the upper ends of the frame side pieces. When all parts of the frame have been positioned with devices in a number of holes, the parts of the frame can be moved along the devices until they have achieved the correct positions relative to each other. It is normal to use wedges or fitting blocks in order to place the frame at a distance from the support, if required. After this, mounting of the fixing devices in the available holes of the parts of the frame is carried out, thus fixing the parts of the frame to the support. Finally, the devices are demounted and replaced by normal fixing devices. If the mounting of the frame refers to a window-frame in the form of a fixed frame construction, the method involves the frame being brought into position in the opening in the support. The position of one corner of the frame is determined and the frame is fixed with a device in the hole that is located closest in either of the two parts of the frame that join at the corner. The complete frame construction is thereafter directionally placed so that the frame is horizontally and/or vertically level, after which a further device is placed in the hole in the opposite parallel-placed part of the frame, relative to the hole that already has been provided with a device. The frame can now be rotated around the two devices and axially displaced along the devices. After this, the frame is further directionally placed and a third device is placed into a hole either in one of the parts of the frame previously provided with devices so that the frame can be displaced along the devices, or in a hole in one of the two other parts of the frame, in order to prevent completely further displacement of the frame construction. The order in which one or several of the devices are placed can, of course, be freely chosen according to the type of frame or relevant wishes about the fixing of the frame, its tilt and its relationship to the surrounding support or some other factor affecting the mounting of a frame. The device and the method can also be used for mounting other building elements, for example building tiles, boards or slabs. The device 1 can also include a constructional part that makes possible the final adjustment of the fixing devices while the device is still fixed to the support and provides guidance for the frame. The constructional part is brought to engage with a fixing device part, which is arranged in the pre-drilled holes of the frame before the device is fixed to the support and which has an opening into which the device is placed, after which the fixing device part can be rotated and the placing of the frame relative to the support can be adjusted. Figure 4 shows an embodiment of a device 1 with such a constructional part. A part of a frame K is to be fixed to a support U. The part K of the frame is provided with holes H to receive fixing devices in the form of adjustment sheaths J designed for the frame. The construction and design of the parts of the fixing devices are previously known. The adjustment sheaths J include an external thread Jl for mounting into the frame. The adjustment sheaths J are further provided with an opening J2 that passes through them, for receiving a fixing element, preferably a screw, for the actual mounting of the frame to the support. The opening that passes through the sheaths is partially formed for receiving a tool for mounting and manoeuvring the adjustment sheaths J. The adjustment sheaths can be arranged in advance in the holes of the parts of the frame before mounting. A device 1 according to the present invention is introduced into the opening J2 in an adjustment sheath J and fixed to the support U. Parts of the internal surfaces of the opening then interact with the external surface of the device and make it possible to turn the frame and/or displace the frame axially along the fixed device. In the situation shown in fig. 4, the device is fixed to the support. The device 1 includes a displaceable sleeve 8 that can be displaced along the device and rotated around its central axis. The sleeve 8 has an outer form that matches the form of the part of the sheath opening J2 designed to receive a tool. When the device 1 has been fixed, the sleeve 8 is pushed into the adjustment sheath J whereby the sleeve 8 engages with the adjustment sheath J and rotational forces can be transferred so that the attachment of the fixing device can be adjusted, and by that the final fixing of the frame relative to the support is made. The adjustment sheath J rests all the time on the support U and the rotation of the adjustment sheath J results in a displacement of the frame K relative to the support U. When the adjustment is completed, the device is demounted and replaced by a suitable fixing element. The present invention has principally been designed to be used with the fixing devices that are currently available on the market. It is, of course, fully possible to design the device and to develop it further in relationship to new fixing devices without losing its innovative concept. Different constructional designs and modifications are possible. The outer form of the sleeve 8 is controlled by the construction of the fixing device and the principal requirement is that the interaction between the sleeve and the fixing device should be satisfactory. The sleeve 8 can be locked, permanently or temporarily, by various methods is its location along the device, provided that it is possible to bring it into its working position relative to the fixing device part. The description of the present invention is not to be seen as a limitation of the invention, but rather as a guide to its understanding.
