Description

The invention relates to a mounting device for mounting a frame in a wall opening.

Usually frames for doors and windows are inserted into the corresponding wall opening assembled by the carpenter manually and with spreading slats, however, only the experienced professional can do it, for example in the case of one Use the door frame with the appropriate frame so precisely that the door then opens Open and close right away.

Instead of the spreading slats, other devices are also known, for example according to DE 42 40 948 A a clamping device for fixing the open side the door frame in the form of a rod, with clamps at the end Sit the clamping jaws to clamp the frame boards on both sides. Also are corresponding frame in the form of a built-in gauge with fixing forks attached to the Attack frame, known from DE 25 38 089 A. A mounting device with Telescopic tubes as a distance construction is known from DE 29 11 234 A. This Mounting device consists of a rectangular frame with two vertical lateral profile frame parts that do not touch the frame, and on these vertical profile frame parts, horizontal telescopic tube parts suspended above and below, their ends with stamp-like widenings on the inside press the frame and its parts after releasing a lock to change the length can be pushed into one another. Instead of looking at the vertical profile frame parts the horizontal telescopic tube parts can also be attached using clips, whose counterpart grips between the frame and the wall. The However, known device is not suitable for a safe, precisely aligned Assemble the frame.

A mounting device on which the preamble of claim 1 is based Genus is known from DE 32 19 066 C. With their help, the frame becomes pliers-like clamps of the mounting device on one side, namely the Ornamental clothing side gripped, and also on this side the device points Jaws to rest on the surrounding wall. Because the parenthesis on the frame and the system on the wall will take place on the same side the frame is subjected to tension in its axial direction and the clamp holders are inclined to damage the surface of the frame.

In contrast, an assembly device is to be created by the invention with the help of the frame in a very short time and with high installation accuracy easy to install without leaving any marks on the frame is. This is done with a mounting device according to that defined in claim 1 Invention achieved. In particular, the contact surfaces of the frame on the Frame, in contrast to the prior art according to DE-AS 29 11 234 vertical frame parts are formed, which form a substantial part of the frame height take, and that on the outer surface. The mounting device lies on both sides of the inner circumference of the frame. The mounting device holds the frame and itself by using brackets on the wall on one side and holders on the frame on the other, opposite Side, whereby pure investment holders are possible, which can only be done without bracketing Apply the required precise fixation to the surface pressure. If the ends of length adjustable horizontal frame parts on the vertical Frame parts are each rigidly attached at a right angle, and there at least one of the vertical frame parts also at a rigid right angle an upper horizontal frame piece is attached that towards the other vertical frame part protrudes and on its top a contact surface for Applying part of the horizontal inner surface of the frame results independently of the mutual alignment of the two vertical frame parts especially with wooden frames and when fixing the miter connections by the System at the given right angle of the mounting frame an absolute miter with precise angles.

The mounting device according to the invention enables both the mounting of a Wooden frame as well as a metal frame. The frame is with the fold side down placed on the elbows of the assembly device lying on the floor, at the miter connections are made in a wooden frame and the Mounting device lying on the floor is from above with the help of The system jaws are fixed so that the frame and assembly device are now firmly connected are. Then the device including the frame clamped therein the opening in the shell is made and with the help of part of the system jaws on the wall provisionally secured. Then the final connection between the wall and Frame made in the usual way, for example by backing and Assembly foam or for steel frames by pouring with mortar. The distance construction e.g. B. in the form of horizontal frame parts prevents this the vertical parts of the frame under the pressure of the foaming agent or Arch the weight of the mortar inwards. After the reaction time of the foam or the curing device of the mortar or the like can be the mounting device dismantled, protruding foam removed and the frame, in the case of a wooden frame, are completed by the decorative clothing. The door leaf can be hung and the closure works flawlessly. By using the mounting device it is possible that with a simple instruction also not annealed Personnel can use the frame properly and gently. But also that Skilled workers need much shorter time to install and can do the job Exercise alone and without outside help, with an orderly one straight away built-in frame is present.

The linkage of the contact jaws on the frame are preferably over one Linear freewheel mounted, the movement of the system jaws in the direction of the Frame and the wall releases and locks in the opposite direction. The Putting on the jaws can be done by hand, which is not a particular one on the frame impermissibly high surface pressure between the investment jaw and Frame leads, performed and retained due to the freewheel effect. It is preferred that the linkage for pivoting the system jaws are rotatably mounted about a respective frame point in the frame and each comprise an arm running parallel to the frame center plane, along which a suspension can be moved for the respective investment jaw. This is one created an easy way to place the frame on the mounting device temporarily swing the investment jaws out of the way and afterwards the contact points on the frame as well as on the wall in certain Choose scope.

At the lower end there are preferably individually adjustable lengths Foot parts, for example those with a screw spindle. This allows the mounting device be set so that the lower ends of the frame the top edge of the finished floor take into account when including the mounting fixture the frame is placed in the shell opening. It is also possible that the mounting device has only a single foot section, which is then in a suitable position in the Course of the width of the device, for example on a horizontal frame part sits.

The frame of the mounting device is preferably located in an area the wall thickness approximately in the middle between the two wall surfaces the wall interrupted by the opening. So that the mounting device can meet this requirement for walls of different thicknesses are expedient the elbows on the frame releasable and new in a different position fixed rigidly fixed. In this respect, the contact surfaces of the contra-angles can be in different distance from the frame parts can be provided.

The angle pieces sitting on one side of the frame are expediently and those sitting on the other side of the frame, at least in each case a linkage bearing linkage with respect to the position on the frame against each other staggered. This will result in no collisions if due to one only thin wall parts of the elbows or rods on the opposite Protrude side of the frame. Another preferred version sees on both sides of the elbows or at least part of the elbows respective plant jaw linkage before, so that the elbow of two Jaw linkage is framed and the frame of transverse bending moments is largely relieved.

The installation of metal frames, in particular, requires somewhat special precautions Steel frames, in which the decorative clothing to be put on later is omitted. After this Inserting them into the wall opening will require additional temporary attachments Parts such as slats or the like are used, which are in the form of formwork when pouring out the gap between the wall and the frame close open column. To hold them on the wall or plaster surface preferably includes the mounting device additional, on the elbows attachable additional holding devices with at a distance from the respective elbow further holding jaws coming to rest. Such metal frames are also located often with different internal dimensions, e.g. B. depending on whether there is a frame with single fold or double fold, although the external dimensions are the standard dimensions correspond. The spacers must be continuously adjustable in this case his. This is, for example, with the help of spreader shears-spindle combinations possible that a uniform frame width over the entire frame height enable. However, since these expanding scissor designs may especially with very narrow doors or frames, in the assembled state Block passing the door opening until e.g. B. the mortar between the wall and frame is cured and the mounting device can be removed preferably the expanding scissor construction combined with a frame construction, in the between an upper and a lower frame part, which in fixed Steps are adjustable in length, there is still a sufficient passage opening remains.

According to a still further improved embodiment, the expansion of the parallel to the frame center plane leg of the elbows rectified expansion of the frame part to be attached to it and carries that individual angle piece in the part of the leg protruding over the frame part an investment stamp that can be moved back and forth towards the center plane of the frame to rest on the surrounding wall. This also allows the Fold side of the frame can adapt to an odd wall, for example the frame can be installed vertically, even if the wall surface is one Vertical inclination. No different treatment is required either of wooden frames and steel frames.

The mounting device thus provides extensive options for mounting Wooden frames, wooden frame frames also with double rebate, wooden block frames with or without rebate and steel frames also with double rebate.

A door frame 1, which is in the outer surfaces by a hatching and in section is represented by cross hatching, has a fold side in a known manner 2 with a fold clothing 3, a decorative clothing side 4 for putting on Decorative clothing 5 (Fig. 4) and an inner surface 6 and one facing the wall Outer surface 7 on. The one shown in section by horizontal hatching Wall is designated 8, it consists of masonry 8 'and plaster strips 8 "(Fig. 4). According to its structure, the frame consists of three frame lining parts 9, which in the case the wooden frame are connected by miter joints 10. From The frame is delivered to suppliers in the form of the three frame lining parts 9, to which the parts are designed for the miter joints.

The dimensionally accurate installation of the frame 1 in a corresponding opening in the wall 8 serves a mounting device 20. This essentially consists of a adjustable width frame 21, elbows 22 to rest on one side of the Frame and system jaws that can be adjusted using appropriate brackets 23 to rest on the other side of the frame and on the wall 8. The frame stands on height-adjustable screw feet 24. Its rectangular extension essentially defines a standing level of the frame, called the frame center level 25 (Fig. 3).

The frame 21 in turn consists of hollow rods according to FIGS. 1 to 5 Rectangular profile or from U-profile rods, preferably made of light metal, since it is on the lowest possible weight is constructed. Two vertical frame parts in the form of Profile bars 28 have respective outer surfaces 29 which are to be applied to the inner surfaces 6 of the vertical parts of the frame 1 are determined. At the top of one of the vertical profile bars 28 is a horizontal one projecting from it at right angles Profile bar 30 rigidly attached, the top 31 with the outer surface 29 of the vertical profile bars forms an exact 90 ° angle and its length is smaller is the width of the narrowest door leaf minus twice the width of the vertical Profile bars 28.

The vertical profile bars 28 are joined together by two or more at execution shown by two horizontal frame parts, namely connecting profiles 32 connected, which are telescopically variable in length and each made an inner telescopic rod 33 and an outer telescopic rod 34, which via holes 35 and pins 36 (Fig. 5) in different lengths are fixable against each other. These linear dimensions correspond to the standard door dimensions. The connecting profiles 32 are rigid on the vertical profile bars 28 arranged at right angles. The right-angled installation of the door frame will guaranteed by this and by the horizontal profile bar 30.

The elbows 22 each consist of two right angles to each other engaging legs, namely a leg 41, which in the illustrated Execution in the outer surface 29 of the profile bars 28 and 30 is sunk, and a protruding leg 42, the system on the fold side 2 of the frame 1 serves. According to an alternative embodiment, the legs 41 of the angle pieces are seated 22 outside on the outer surface 29 and on the inner surface 6 of the frame the outer surfaces projecting relative to the outer surface 29 Leg 41 created.

The elbows 22 are according to Fig.n 1 to 5 and 8 to 11 to the vertical Screwed profile bars 28 and the horizontal profile bar 30, whereby they Adaptation to different wall thicknesses and for the purpose of one if possible thickness-wise central arrangement of the mounting device 20 in the frame 1 of the vertical profile bars 28 protrude further or less. For example, in 4 and 5 show the system on a thick wall, for example a starch of 270 mm, shown and in Fig.n 8 and 9, the system on a thin wall, for example, 100 mm thick.

On the opposite legs 42 of the elbows 22 On the side of the frame 21 or the level 25, the contact jaws 23 each sit on a linkage consisting of an L-bar 45 of round bar cross-section and one on one of the legs of the L-bar 45 along this and if necessary also along the length of the stem 46, which is longitudinally displaceably attached Wearing investment jaw 23 exists. The L-rod 45 is not the stem 46 with its supporting leg through corresponding holes in the hollow profile of the vertical Profile bars 28 and the horizontal profile bar 30 inserted and in this rotatable. Within the respective hollow section bar 28 or 30, the L-bar engages a linear freewheel 47 on, by a release lever 48 out of function can be set. The linear freewheel 47 is in the drawing as a coil spring freewheel shown, but there are many known ways of doing this in the art such as clamping and wedge constructions.

The linear freewheel 47 is inserted so that the rod 45, from the decorative clothing side seen from, pushed by hand into the frame 21, but only after release by the release lever 48 can be pulled out again. In this way, the relevant investment jaw 23 can be used for contact with a solid body be pushed forward and pressed, this solid body depending on the Position of the stem 46 on the pivotable leg of the L-bar 45, the decorative clothing side 4 the frame 1 or the plaster of the wall 8 can be. The pressing only by hand force limits the surface pressure of the investment jaw 23 on the component in question, which can therefore not be damaged.

In Fig. 1, the relevant investment jaw 23 is dashed in some places in a Shown position shifted along the L-bar 45. There is also one Place the pivotable leg of the L-bar 45 in dashed lines in a variety possible angular position shown to illustrate the pivotability. In the embodiments shown in FIGS. 1 and 2 sit on each vertical profile bar 28 three angle pieces 22 and three contact jaws 23 in addition associated linkage, and an angle piece 22 sits on the horizontal profile bar 30 and an investment jaw 23 with linkage. The elbows 22 and the anchorages of the L-bars 45 along the profile bars 28 and 30 against each other offset and not exactly opposite. This is advantageous in that thereby spatial collisions on the one hand between those in different positions screwable legs 41 of the elbows 22 and the other hand the L-bars 45 can be avoided. Such collisions would otherwise be especially in the case of thin ones Walls to fear.

It could be considered to omit the horizontal profile bar 30 and its function through the outer telescopic rod 34 of the upper connecting profile 42 to have effect. However, this is not the case in the embodiment shown Appropriately, since on the one hand the L-rod with the linear freewheel 47 and on the other hand the telescopic construction of the parts 33, 34 in the same component only poorly with one another would be compatible.

The mounting device 20 is used for the installation of a wooden frame in the following manner used. First, on the frame 21, the elbows 22 in one of the Wall thickness including plaster screwed appropriate position, z. B. two screw-on positions are provided. Then the frame 21 with the Elbows 22 placed on the floor and on using the connecting profiles 32 the clear width of the frame is set. To possible manufacturing tolerances or This position can compensate for foam pads by a few millimeters to be changed.

The wooden frame 1 has been delivered in three parts with two miter cuts. The parts are on the protruding legs 42 of the lying on the floor Mounted device 20 and the miter connections are fixed. By the predetermined 90 ° angle between the outer surface 29 of the vertical Profile bar 28 and the top 31 of the horizontal profile bar 30 is the Miter easily manufactured at an angle. The frame itself comes here not with the floor, which can still be rough concrete, for example Contact. After placing the frame and creating the corresponding Surfaces 6 and 29 or 31 to one another are the frame with the help of some, as shown in FIG. 1 with two of the system jaws 23 clamped on the mounting device and is then rigidly connected to it. Now the screw feet 24 are adjusted so that an adaptation to the upper edge of the finished floor is made on the the frame should sit on. Then the assembly device is included the frame stretched thereon is placed in the shell opening so that the folded clothing side fits well on the plaster of the wall 8, and is with some, for example 1 with four system jaws 23 a counter-system of Assembly device-frame combination on the opposite side of the wall made so that the frame sits firmly on the wall.

On the assembly device 20 there are dragonflies, not yet shown, or a spirit level is put on to check the position of the frame and if necessary, by adjusting the contact jaws 23 into the desired one Positioned and wedged with wooden tiles or wedges. Then can the final connection between the shell wall, which is naturally a rough one Has outer surface, and the frame can be produced, for example by backing made of wood or plastic and assembly foam, through adhesive foam, etc. The Mounting device 20 supports the frame against the possible foaming pressure from the inside. Now the foam or other must harden Cavity filling between the wall and frame can be waited for before the mounting device can be dismantled again. Any excess foam will removed and the frame is completed by the decorative clothing 5. Subsequently the door leaf is hung in and the previously used assembly device is placed sure that the closing of the door leaf now works perfectly.

The operation of the mounting device described is also the non-specialist possible. The mounting device can, for example, as a loan device for the purpose of Self-installation of frames are available. But also for the specialist the frame can be assembled quickly by just one person.

The mounting device is also for the installation of a metal frame, for example a steel frame can be used. The prerequisites are somewhat different here, as here no decorative clothing on the side that corresponds to the decorative clothing side of the wooden frame is placed and the steel frame on this side preferably with a a reasonably precise, straight wall finish. The gap between the masonry and the steel frame is usually done with mortar poured out.

Fig. 10 shows the application of the mounting device in a steel frame in which no additional measures are required due to the opening of the wall. Between the wall 8 and the frame 1 there is a cavity 50 which is completely clean locks and is poured with mortar.

In contrast, the situation is shown in Fig. 11 that there is between the wall 8 and the frame 1 there are gaps. In this case, first the contra-angles 22 equipped with a screw-on additional part 51, which is still in on the left in FIG loose state and next to it is shown in the fully assembled state. This comprises a screw ram 52, which is pre-screwed in the direction of the wall 8 can be. With the help of the screw plunger 52, the over the Height only locally occurring gap between the folded edge of the frame 1 and the Plaster the wall 8 through a sealing rod 53, for example a wooden slat can be closed. The stamp 52 presses this sealing rod 53 against the wall 8 and thus closes the cavity 50 between the Wall and the frame. The additional part 51 and its assembly are in Fig. 12 in illustrates a larger representation.

On the opposite side there is another sealing rod in the same way 53 inserted between the edge of the frame 1 there and the wall 8 and through a or held more of the investment jaws 23. This is the cavity 50 between the wall 8 and the frame 1 sealed on both sides and can now be filled with mortar.

13 shows a side view of a modified mounting device, that on the vertical frame part 28, the middle angle 22 on both sides of System jaws 23, each on one of the L-bar 45 and the handle 46 existing linkage sit, is flanked. This results in improved System conditions and power flows both with regard to the grip on the mounting frame as well as with regard to the system on the wall. Both sides Angle pieces 23 flanked by contact jaws 23 are also in the following described embodiments (Fig. 18) available.

In the embodiments described so far, it was assumed that that the elbow 22 by fitting the corresponding frame part can be adapted to the wall thickness. So that the mounting device 20 about to attack in the middle of the frame, this must be the case with thick walls Elbow 22 are extended further than with thin walls.

14 to 17 illustrate an alternative embodiment in which the Elbow 22 in its seat on the respective frame part, which in Profile bar is sunk and is guided with respect to its opening movement, has rectangular teeth 57, between which one on the frame part, in the illustration on the profile rod 28, rotatably seated locking bolt 58 engages, which engages between teeth 57 and for its detachment from the teeth using a handwheel 59 is rotatable, the rotational position of which is in turn by a clamping screw 60 can be locked. The teeth can be provided with a suitable scale, which in in the manner indicated in FIG. 17 is related to the wall thickness. The profile bar 28 is shown twice in Fig. 17, once at the point of passage of the L-bars 45 and once at the point of passage of the elbows 22. The Fixing the elbows 22 is used for a conventional latch construction 61 Angle piece 22 is a scale 62, which is indicated by dashed lines Way is related to the wall thickness.

Figures 18 to 24 relate to a modified embodiment that relates to it relates that occasionally frames, especially steel frames, are not the standardized ones Have dimensions. The illustrated in Fig. 6 distance adjustment between the vertical frame parts 28 is, however, only to a limited number of frame widths adjustable. FIGS. 18 and 19 therefore show an assembly device, in which the distance adjustment is partially staged using the telescopic tubes 33 and 34 and partially continuously with the help of spreading scissors 65. Here, the vertical profile rod 28, which runs on the side of the telescopic tubes 33, 34, as well as in the previous exemplary embodiments, be a full rectangular profile, while the opposite frame part in any case in two half-profile bars 66 and 67, each having a U-section, the open sides of which are directed against each other, and between which the spreading scissors 65 are used are.

Each spreading scissors 65 consists of two scissor arms 70 and 71, which are in mutual X configuration arranged and at their crossing point by a bearing 72 are interconnected. The bracket 70 is in the half-profile rod 66 by a bearing 73 pivoted and the bracket 71 is in the half-profile rod 67 by a Bearing 74 pivotally mounted. The lower ends of the scissor arms 70 and 71 each run with a slide pin 75 in an elongated hole 76 and 77 in the lateral U-legs of the half-profile bars 66 and 67. runs in the half-profile bar 67 from bottom to top a screw spindle 81 with a lower crank 82 for manual twisting. Nuts 83 are screwed onto the screw spindle, which arranged non-rotatably in the half-profile rod 67 and one each with the lower end the scissor bar 70 or connected to the slide pin 75. In the area of Bearing 74 of the lower spreading scissors 65, the screw spindle 81 runs without Thread contact through a sleeve 84. At the top, that's in the area arranged between the bearing 74 and the slot 77 of the upper spreading scissors 65 can be, the spindle 81 is rotatable, but axially immovable in one Version 85 stored.

By rotating the crank 82, the spindle 81 is rotated. Since they are not axial can dodge, it screws the nuts 83 and thus the sliding pins 75 depending on Direction of rotation up or down. As a result, the spreading scissors 65 in their spread angle is changed and the distance between the half-profile bars 66 and 67 changed. The whole system has sufficient self-locking, so as not to be adjusted by an acting lateral force.

With this arrangement, the distance is adjusted in the following way:

For placing the frame on the elbows 22 of the assembly device lying on the floor 20 is first of all by inserting the pins 36 into suitable pairs of the Holes 34 preset the width of the mounting device 20 so that the inner Width of the frame 1 is almost reached. The measure that is then still missing is indicated by Actuation of the crank 82 is set, the two half-profile rods via the spindle 81 66 and 67 apart according to arrows 90 (Fig. 21) or, with the reverse Direction of rotation, moved towards each other again according to arrows 91.

The through the profile bar 28, the half-profile bar 67 and the upper and lower Telescopic rods 33 and 34 formed subframe of the mounting device can not become narrower than the length of the outer telescopic rods 34 corresponds. This are according to a preferred dimensioning from the inner edge of the vertical profile bar 28 400 mm long, with the result that even with the narrowest with the mounting device 20 frames that can still be installed always have a passage opening of 40 cm Width remains through which the fitter during the setting time of the mortar or the like can slip through. This is the narrowest frame inside width with this preferred dimensioning and on the basis of a width of Profile bars and half-profile bars 28, 66 and 67, when the latter is completely pushed together are (Fig. 21 above) 550 mm. On the other hand, this dimension results a maximum inner width of the still mountable frame of 1150 mm.

23 illustrates the adjustment of the width of the mounting device 20 between a minimum and a maximum.

24 shows an assembly device with modified angle pieces 92, whose protruding leg 42 'beyond the width of the folded clothing 3 is extended and at the end of another movable contact element, the is a screw punch 93 in the example shown. The screw stamp 93 can be advanced and placed against the surrounding wall 8. This allows the Frame 1 also with a gap between your folding clothing 3 and the wall be mounted, for example vertically with a wedge-shaped gap with an inclined Wall 8, as illustrated in Fig. 27: left with vertical wall 8, right with inclined wall 8, but still vertical frame 1.

Another modification of the embodiment of Fig. 24 is that of the Plant jaws 23 those who put on the decorative clothing side 4 of the frame 1 have a smaller contact area than those contact jaws 23, to be put on the wall 8. Since both plant jaws as round disks trained, they differ in their diameter.

25 illustrates the frame assembly by a schematic perspective View with parts partially broken away, whereby side by side 24 two frames 1 are shown, one of which the viewer Folded side and the other facing the decorative clothing side. The mounting fixtures 20 are shown in black, and in the middle between the frames 1 is through a wall breakthrough from the assembly device shown on the right 20 also a fold-side angle piece 22 is visible.

Fig. 26 shows sections through the area wall-frame profile bars of the mounting device 24, each approximately in a sectional plane corresponding to the plane the L-bars 45, for four different cases, namely a) normal for a wooden frame, b) for a wooden frame with compensation, c) for a steel frame normal and d) for one Steel frame with compensation or sealing, the latter with the z. B. as a wooden board executed sealing rod 53.

FIG. 28 schematically shows a structurally simple possibility for the linear freewheel 47 shown. It consists of a leaf spring 94 mounted on the profile bar 28 or 30 with an elliptical hole 95 through which the L-bar 45 passes.

29 shows an additional possible padding 96 for the angle piece 22 greater protection of the frame surface.
