<heading id="h0001">THE FIELD OF THE ART</heading>
<p id="p0001" num="0001">The invention relates to an angular joint employed in the process of angular connections of hollow profiles, such as in the orthogonal connections of profiles being previously cut at 45° and coming to contact to form parallelepipedal frames for doors or windows.</p>
<p id="p0002" num="0002">Joints for door and window profile frames of the prior art of the type of spring activated button means removably engaging into suitable apertures of the profiles to stabilize the angular connection thereof, require, prior to employment thereof, the opening of apertures at precisely selected locations of the profiles wherein are removably engaged the abovementioned spring activated buttons. This process is awkward and time consuming due to the accuracy required in marking and drilling of the apertures and often leads to an imperfect fit of the profiles and to a structure of reduced aesthetics and functionality due to the non-alignment of the profiles.</p>

<p id="p0005" num="0005"><patcit id="pcit0006" dnum="GB2072296A"><text>GB-2 072 296</text></patcit> discloses a joint wherein a clamping member is moved through a bolt being screwed along the line of matching contact of the profiles so that opposed hooks of the clamping member are drawn into engagement with punched depressions in the outside walls of the hollow sections being connected. Application of such a joint in practice requires employment of the specific type of profile being proposed in this patent, whilst the requirement of punched depressions at precisely measured locations, worse than the opening of side apertures onto the profiles to be connected wherein the nature of openings might allow marginal fitting tolerances, poses a further problem that the dimensions of the profiles having being cut and punched or perforated industrially cannot be altered on site, as their installation might require, because the punches/perforations would move out of place and would therefore render the joint inapplicable.</p>

Although this joint is mainly directed to serve a permanent connection of the profiles, if disconnection of the frame is desired, one has to attempt, through slots in the profile walls, to pry inwardly the profiles and release them from jamming engagement. Although simple, the joint in US-5, 109,645 is unable of obtaining perimetrically precise contact of the profiles being connected, thereby leading to technical and aesthetic drawbacks, whilst its structure does not render it capable of withstanding heavy loads in the range of tons,<!-- EPO <DP n="3"> --> normally required with door/window frames, without creating undesirable gaps along the plane of matching contact of the hollow profile sections.</p>

<heading id="h0003">DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS</heading>
<p id="p0012" num="0012">The joint of the invention is particularly related with the assembly of frames that are being assembled from previously cut lengths of profiles e.g. aluminium or plastic profiles, such profiles having a hollow section to allow introduction and operation of the joint. A broad, but not exclusive, field of application of the invention is the connection of profile members in the corners thereof, when they are brought together to form generally parallelepipedal frames or casings for door and window applications. Such profile members are previously cut at 45° at the matching edges thereof to allow for an optimally aesthetic fit of the orthogonal connection.</p>
<p id="p0013" num="0013">Thus, whilst the joint of the invention has a necessarily orthogonal configuration in the particular application, it may equally well have the configuration of an acute or an oblique angle to serve applications wherein the hollow profile members are connected at an acute or an oblique angle respectively.</p>
<p id="p0014" num="0014">The dimensions of the joint of the invention may naturally vary to make it compatible with different sizes and sections of profile members.</p>
<p id="p0015" num="0015">An illustrative hollow profile member 50 is shown in <figref idref="f0001">Fig. 1a</figref>, such profile member 50 comprising a pair of parallel walls 50c, 50d extending on the one hand at an open end 50a wherein is fitted the item that is being framed by such perimetrically covering length of the profile member, e.g. a glass or shutter panel for a door or window assembly, and on the other hand<!-- EPO <DP n="6"> --> at and end 50b, opposite to the open end 50a, end 50b being fixedly mounted to the casing. A chamber 13a,b is formed in between 50a and 50b, such chamber serving for the introduction of the joint of the invention. Whilst other details of the profile members to be connected may vary, the chambers 13a,b are available for the employment of the joint of the invention. The drawings therefore depict the abstract detail of such rectangular chambers 13a and 13b with respective open ends 12a, 12b of the hollow profile members being brought together for connection.</p>
<p id="p0016" num="0016">The joint of the invention shown in <figref idref="f0001">Fig.1</figref> comprises a fixed slide base portion 1 and an elastically deformable sheet metal portion 2 superimposed onto the fixed slide base portion 1 and having a configuration that generally corresponds to the surface of the base portion 1 whereupon it is being seated. Both portions 1 and 2 are symmetrically arranged on either side of plane x-x' (<figref idref="f0002">Fig. 2b</figref>), a central bolt 3 with a screwing head end 3a and a sharp edge 3b also passing through the same plane of symmetry x-x' being driven by means of a screw driver 14, wherein this plane of symmetry x-x' coincides with the plane of contact of the two hollow profile members being brought together for connection.</p>
<p id="p0017" num="0017">The fixed slide base portion 1 is an angular item with a pair of planar outer sides 1e forming an angle corresponding to the angle at which the profile members are being connected, at this instance an angle of 90°, a slight planar recession 1g being formed near the junction of these outer sides 1e, such planar recession 1g serving as a means of overcoming possible obstacles in the course of sliding of these outer sides 1e onto the walls of corresponding chambers 13a, 13b, that might be due to possible imperfections in the cutting and finishing process of the edges of the metal profile members being brought together for connection. The slide base portion 1 forms a flat basement portion 1a overlying the junction of the<!-- EPO <DP n="7"> --> above outer sides 1e with a cavity 1b being centrally located thereupon to serve the purpose of receiving the sharp edge 3 b of bolt 3.</p>
<p id="p0018" num="0018">On either side of the above flat basement portion 1a, that is perpendicularly oriented with regard to the plane of symmetry x-x' the inner sides of the fixed slide base portion 1 extend to a pair of planar sections 1c which are substantially parallel to the walls of profile chambers 13a,b whereupon the outer planar sides 1e are seated and subsequently extend into convergent portions 1d terminating at symmetrically located edges 1f. The herein above described configuration of the sides of the fixed slide base portion 1 substantially improves the characteristics of the process of sliding of the sheet metal mobile portion 2 onto the fixed slide base portion 1 as will be explained hereinafter.</p>
<p id="p0019" num="0019">The sheet metal mobile portion 2 has a configuration generally identical with the configuration of the slide base portion 1, with an upper basement 2a with a centrally located cavity 2b wherein is being driven the sharp edge 3b of the tightening bolt 3, wherein the upper basement 2a lies perpendicularly to the plane of symmetry x-x' and symmetrically above the basement 1a of the base portion 1. In turn, the upper basement 2a symmetrically extends to planar side surfaces 2c and 2d, each with a length generally equivalent to the length of underlying surfaces 1c, 1d of the base portion 1, whereupon they slide.</p>
<p id="p0020" num="0020">The sheet metal mobile portion 2 is bent upwardly at the terminals 2f of side surfaces 2c-d at an angle (180-θ)° as illustrated in <figref idref="f0003">Fig. 2c</figref>, and extends to upwardly extending sides 2e on either side thereof terminating at sharp edges 2g, such upwardly extending sides 2e thereby being oriented in a direction substantially parallel to the plane of symmetry x-x'.</p>
<p id="p0021" num="0021">In accordance to a first preferred embodiment of the invention the abovementioned centrally located cavity 2b in the sheet metal mobile portion<!-- EPO <DP n="8"> --> 2 is drilled through to form an opening with internal threading for the passage of bolt 3. In <figref idref="f0006">Figs. 7a-c</figref> are depicted possible alternative solutions for implementing such hole with internal threading. In <figref idref="f0006">Fig. 7a</figref> hole 2b is being formed by expansion of the sheet metal into a cylindrical collar 19 that is subsequently internally threaded. In <figref idref="f0006">Fig. 7b</figref> is depicted an alternative solution of employment of an additional plate 18 having a planar surface 18a with dimensions such as to fit onto the basement 2a of the sheet metal portion 2 and a central hole 18b that is internally threaded and coincides with hole 2b on the basement 2a when plate 18 is brought in contact with basement 2a. Finally in <figref idref="f0006">Fig. 7c</figref> is depicted an additional internally threaded cylindrical collar 48 with a body portion 48a and a central hole 48b coinciding with hole 2b of the sheet metal portion 2.</p>
<p id="p0022" num="0022">In the case wherein cavity 2b in the sheet metal portion 2, is drilled through and forms a thorough internally threaded hole, such hole being implemented in either one of the illustrative embodiments of <figref idref="f0006">Figs 7a-c</figref>, bolt 3 is driven through this hole 2b and terminates by contact of the sharp edge 3b thereof onto the cavity 1b being provided axially underneath hole 2b on the fixed slide base portion 1. Whilst this condition corresponds to the joint having been assembled but not tightened as shown in <figref idref="f0002">Fig. 2a</figref>, when as shown in <figref idref="f0002">Fig. 2b</figref>, by means of screw driver 14 the bolt 3 is being screwed, the force being exerted by the firm contact of the sharp edge 3b thereof onto the cavity 1b of the slide base portion 1 maintains the latter firmly in contact with the walls of the profiles being connected, whilst it produces a reactive force that pushes upwardly the sheet metal mobile portion 1 until the sharp edges 2g thereof indent the relatively softer walls of the profile members being connected, thereby achieving a robust, self aligned connection thereof, such self alignment being obtained as a result of the above mentioned indenting of<!-- EPO <DP n="9"> --> the walls of the profile members extending along a substantial length of the sharp edges 2g of the sheet metal mobile portion 1.</p>
<p id="p0023" num="0023"><figref idref="f0003">Fig. 2c</figref> characteristically depicts a magnified view of a detail in the process of tightening of the joint of the invention. Herein is shown that following indenting of the sharp edges 2g of the sheet metal portion 1 into the walls of corresponding chambers 13a, 13b of the profiles to be connected, further screwing of bolt 3 results in a perfect convergence of the profiles to be connected along the axis of symmetry x-x', whilst the upwardly extending sides 2e of the sheet metal portion 2 move through an infinitesimal distance a', having a length of the order of a fraction of a mm, thereby being deflected at an angle θ'° relatively to the side surfaces 2d of the sheet metal mobile portion 2. Resilient stresses are thereby stored in sheet metal portion 2, uniformly applied on either side of the joint, such stresses thereby maintaining the joint in a tightened condition and the profile members rigidly connected even if an accidental slight release of bolt 3 may occur.</p>
<p id="p0024" num="0024">In accordance to an alternative embodiment of the invention, instead of opening a hole through the above cavity 2b in the sheet metal mobile portion 2, a hole is drilled through the corresponding coaxial cavity 1b of the fixed slide base portion 1 as shown in <figref idref="f0003">Fig. 3</figref>. The bolt 3 is then being driven from the inner junction of the profiles to be connected and sharp edge 3b thereof firmly contracts sheet metal portion 2 at cavity 2b thereof and exerts a raising force thereupon, eventually resulting in the indentation of the walls of the profiles to be connected by the sharp edges 2g of the upwardly extending sides 2e of the sheet metal mobile portion 2.</p>
<p id="p0025" num="0025">The form of the sharp edges 2g of the upwardly extending sides 2e of the sheet metal mobile portion 2 is selected so as to render an optimum indentation effect. Thus, they may for example have the toothed form<!-- EPO <DP n="10"> --> depicted in <figref idref="f0001">Fig. 1</figref> or <figref idref="f0004">Fig. 4a and Fig. 4b</figref> or they may take the double razor edge like form of edges 20g in the upwardly extending sides 20e of an alternative embodiment of the invention depicted in <figref idref="f0005">Figs 5, 5a</figref>, wherein the mobile portion 2 of the joint of the invention is made from a profile of hard aluminium alloy with an upper basement 20a provided with a centrally located hole 20b and sides 20c - 20d in sliding contract with corresponding sides of the underlying slide base portion 1. A single razor edge ending of upwardly extending sides 20e of the mobile portion 20 made from hard aluminium alloy may be equally effective in the indentation of the relatively softer walls of the hollow profiles to be connected, however the double razor edge like configuration further serves the purpose of a secure sequential indentation of the walls of the profile members.</p>
<p id="p0026" num="0026">Alternatively, as shown in <figref idref="f0005">Fig. 5b</figref>, the upwardly extending legs 20e of the mobile portion 20 may form a recession, wherein an independent sheet metal plate 15, preferably with toothed edge configuration may be fitted to serve as an indentation means.</p>
<p id="p0027" num="0027">A further alternative embodiment is shown in <figref idref="f0005">Fig. 5b</figref>, wherein legs 20e may extend to a plurality of pointed pins 20g'.</p>
<p id="p0028" num="0028">Finally in <figref idref="f0006">Figs 6a, 6b</figref> the sheet metal portion 2 is alternatively made with side surfaces 2c ending at a bent structure of the sheet metal portion forming a recession 17 for the engagement of a wire 16, made from steel in the form of a II section in substitution of the otherwise planar sides 2d of the sheet metal portion 2, with the legs thereof bent to upwardly extending members with sharp edges 16g playing the role of profile wall indentation elements. In this embodiment, the fixed base portion 1 may be made in two identical portions, symmetrically on either side of the plane of symmetry x-x', the two identical portions being pivotally connected around a pivotal axis 60 and thereby being appropriate for the connection of hollow profiles<!-- EPO <DP n="11"> --> forming varying angles at the junction thereof. The sheet metal mobile portion 2 might under such circumstances also be adjustable to profile connections at varying angles with the pivotally mounted end portion 16 thereof.</p>
<p id="p0029" num="0029">The fixed slide base portion 1 of the joint of the invention may also receive alternative forms. In <figref idref="f0004">Fig. 4a</figref> base portion 1 is provided with elevated end walls 6 with opposing central nerves 5 that fit into recessions 4 of the sheet metal mobile portion 2. Alternatively in <figref idref="f0004">Fig. 4c</figref>, base portion 1 does not terminate in the abovementioned terminals 1f, but is bent upwardly following a configuration similar to that of the sheet metal portion 2, so that the upwardly extending legs 2e of the latter may fit into the recessions being formed by the upwardly extending legs 1e' of the fixed slide base portion 1.</p>
