In addition, the setting of the device in all spacial directions is to be possible over a wide angle region, the adaptation of the device to different connection shapes is to be set in a simple manner, as well as a disengagement of already fixed connections can again be quickly performed and a reuse of the adjustment device and fixing device is to be possible.
This object is accomplished with the features of the characterizing parts of claim 1 in connection with the initially recited kind according to the preamble of the claim 1. The sub claims refer to particularly advantageous embodiments of the Invention and form together with claim 1 simultaneously a part of the description of the Invention.
The construction of an adjusting and fixing device for the fixation of building parts of an arbitrary kind, in particular however of hanged over facade pre-constructions, out of a base body, wherein attachment bodies rotatably and swivelably are employed in the end region, wherein the attachment bodies are disposed between opposite to each other to be fixed building parts and are attached to these building parts, there results a free setting possibility of the building parts relative to each other. The disengageable fixation in the desired position by employing small pressure forces is possible based on applying a wedge piece inserted into the base body at a right angle to the pressure transferring shiftable pressure bodies, wherein the hinged attachment bodies freeze and resist to high counter forces at a right angle to the small pressure forces based on a high friction of forces between the attachment bodies and the base body.
A particularly frequently applied form of an adjusting and fixing device comprises the application of a wedge piece between two shiftable pressure bodies.
A maximum of hingeability and therewith of adjustability is accomplished, where the attachment body is applied together with a ball part or also with a shell of a sphere part in the base body and wherein an attachment bolt is attached at the attachment body solidly, perhaps as a single piece in case of a forged part, wherein the forged part then can employ an arbitrary attachment part at its free end, wherein the attachment part is applied for the building region, for illumination purposes, for the positioning of sensors or cameras and the like.
The simplest and usually most favorable form is the use of a cylindrical tube as a base body, wherein the ball part or the shell of a sphere part of the attachment body is placed into the base body also because of the fixation function with the small play, wherein the attachment bolt is swivelable over a very wide angle region and in addition is rotatably disposed.
It is also possible to employ a molded tube with a square or a hexagonal cross-section, in case the use is employed for the adaptation of predominantly the ball part or the shell of a sphere part.
The application of a snap ring as a support part in a hollow recess or of an insertion screw part in an inner winding as for the ball part or the shell of the sphere part for easier mounting and particular demounting, wherein the snap ring or retention ring is suitable for support under high friction or where the demounting is dispensed with, then also the narrowing upsetting of the tube can be employed for support. Based on the dismountable construction of the adjusting and fixing device, the exchange of parts can be performed without particular expenditure and an adaptation, with the different attachment bolts and/or different complete attachment bodies can be performed with respect to changing requirements relative to attachment, load, and geometric dimensions.
The possibility of the application of an attachment bolt at the ball part of an attachment body comprises the use of a thread, in particular where smaller production numbers are involved.
Furthermore it is possible to perform the connection with welding, soldering, frictional welding, riveting, or adhesive attachment even though a single piece forged part is preferred.
The attachment part of the attachment bolt is for example furnished as an anchoring screw for attachment in the wall of a masonry wall and the use of an angled piece or a corresponding screw connection is suitable for attachment to a wood construction, wherein the screw connection can comprise a nut and a counter nut or other standard parts are employed such as they are usually employed in connection with support stands for illumination, photography, sound transmission and the like.
The edge of the tube of the base body coordinated to the attachment bolt is furnished with one or also several recesses for screwing in of an adjustment and fixing device for example in the wall, wherein the breadth and depth of the recesses at least correspond to the diameter of the attachment bolt, that is corresponding to the key width of the hexagon profile of the attachment bolt, such that a screw tool is generated by swiveling of the attachment bolt in the recess of the edge.
In order to avoid flipping, the pressure body is the supported with a small play in the tube or in the insert of the tube and the pressure body is concavely adapted to the ball part or to the shell of sphere part and furnished with a ball shaped convex or a cylindrical convex pressure face relative to the pressure generating wedge piece, in order to keep the friction low.
The wedge piece can be formed either as a pressure wedge piece or as a pull wedge piece and is the most favorably positioned about in the middle of the tube of the base body, wherein two pressure bodies are furnished for two attachment bodies, which attachment bodies then have the same length. The wedge piece is furnished with a thread for a screw connection or with an actuating bolt for a hydro mechanical or electromechanical set member for the remote actuation.
The tube of the base body is furnished with a formed inner thread for adjustment of the pressure wedge, wherein the inner thread is applied in a formed on tube socket for improvement of the guiding and for receiving of the counter force or which inner thread is applied in a nut welded on above a bore hole. In case of a pull wedge in contrast, a bore hole is provided in the queue with the milled key face for this seat of the pull nut on the thread of the bolt extension of the pull wedge piece.
The wedge piece is furnished with a guide in a guide bore hole in the tube jacket at the oppositely disposed tube side of the base body of the adjusting and fixing device for improvement of the guiding for the support of the wedge piece.
The hardening of the pressure faces with high surface hardness and the formation of high strength is favorable for the durability of the wedge piece, since thereby a forming at the pressure bodies is accomplished in a limiting case, by way of which the safety against turning of the complete hinge is increased.
For improving the rigid position of a hinge against rotation, it is possible to furnish the pressure body with one or also several back centers at that face which is the directed toward the ball part, wherein the back centers are somewhat staggered out of center relative to the axis of the hinge and wherein the back centers press themselves into the ball base, in order to secure in a better way against rotation. It is also possible to produce the fixation with an inserted ring or with several part rings or with inserted hard metal or with hardened steel balls. The repositioning and the opening of the hinge can be furnished with a pressure spring inserted between the pressure body and the ball part.
It is important for the production of a stable scaffold under use of a plurality of adjusting and fixing devices to position the attachment bodies of successively following or next to each other disposed base bodies to the attachment bolts spatially changing deviatingly in three spacial directions; this is in particular of importance in connection with facade pre-fronts because of their size and their weight.
The dismountable construction of the adjusting and fixing device is favorable for the saving use and for the rebuilding and for changes in the construction, since attachment bodies or pressure bodies can be exchanged and can be alternated with such elements of different construction type.
A very quickly adjustable and fixable adjusting and fixing device is generated with this Invention construction, wherein the adjusting and fixing device can be employed in a wide region and can be reused after deployment.
The construction allows handles of up to 60 degrees and more in all spacial directions and the attachment bodies of which are combined arbitrarily with each other already at one device and can be employed according to a building block system, depending on need in a wide load and distance region. The fixation can be performed rapidly and precisely and offers a tremendous alleviation of work in case of commercial employment.
In case of application for pre-hung elements such as frame wood of facades, then be recited advantages are very substantial in particular also in connection with passive houses with the pre-mounted wood construction with up to 30 cm heat insulation placed in front of a brick wall.
The dowel plugs are applied at the application location staggered on two sides for attaching of the frame wood and the adjusting and fixing devices are screwed in without tool with the attachment bolt in screw connection position, wherein the oppositely disposed attachment bolt carries a screw for screwing in. Thereupon the frame wood is mounted in the predetermined position and distance. The inclined relative to each other staggered arrangement of the devices results always in a triangular or trapezoidal arrangement with high stiffness in all dissections.
The fixation at a frame part is alleviated, in particular when this frame part comprises wood, with the grooving over sufficient length at the free end of the attachment bolt of an attachment body of the adjusting and fixing device, since then the fixation is reinforced by pressing into wood. The fixation with an attachment part, presented in the shape of a loose angled piece, is performed by screwing in each case, also in case of frame parts made of metal easily changeable and stable, wherein perhaps a counter plate is employed at the frame part.
An angle formation of the attachment bolt is advantageous, narrow at the attachment position at the attachment body, with an angle relative to the bolt axis of from about 10 to 45 degrees, wherein the 30 degrees are particularly advantageous, in order to apply frame parts of a pre-wall completely at a masonry wall, simultaneously the resistance moment is the very much enlarged at a small distance of an angle formation caused by the lever action. Furthermore several adjusting and fixing devices can be applied therewith in a substantially simpler way in a triangle combine aligned at an inclined angle in all spacial directions, by way of which an extraordinary stiffness and loadability can be achieved, while the arbitrariness of the arrangement of the adjusting and fixing devices remains present nearly without limitation.
The connection of the attachment bolt furnished with a grooving is here achieved with an attachment part, wherein the attachment part is formed as a loose angled part having an impression for the attachment bolt, wherein the impression is applied at the right angle running relative to the angle formation and equipped on the inside with grooves and furnished with an attachment arrangement for applying preferably at wood.
The loose angled piece is furnished for the leading through of the free end of the attachment bolt at the angle formation, furnished for impressing with the passage opening, wherein an adjustment of the attachment bolt in its longitudinal axis is possible over a wide region, wherein the grooves of the attachment bolt with the groove structure of the impression result in a stable fixation as soon as the angled piece is screwed onto a frame part.
For this purpose the arm with the impression is furnished with bore holes for screw connections; wherein the attachment at frame parts out of wood can be reinforced with the forming in of the attachment bolt of from 1 to 2 mm into the wood.
With this arrangement there's generated a height level adjustable frame angle, wherein the height level adjustable frame angle substantially simplifies the assembly and the mounting.
