TECHNICAL FIELD

The present invention relates to a semi-invisible combination of thermal insulating profiles of the lower part of sliding doors and windows which allows the unhindered passage of people and objects above it, the positioning of the invention allows the flatness and uniformity of indoor and outdoor floor coverings as well as the creation of small width grooves on the floor, which consists of the following:

Of at least one thermal insulating profile (1) with one or more movement grooves which is firmly attached to the structural components of the building and which is called "Frame" (1)

Of at least one thermal insulating profile from PVC or Polyamide (3) which is called "sash" and which is equipped with the appropriate U shaped channels (18) in order to receive heat insulating panels or glazing. (19)

Of at least one tubular thermal insulating profile or assembly of insulating or not profiles which is called "added horizontal support" (2), connected to the "sash" (3) in such way which allows the linear contractions and expansions, whom cavities (33a), (33b), (33c) and (33d) can potentially be filled, with heat insulating materials or reinforced profiles. Moreover the "added horizontal support" (2) comprises from wheels (20a), (20b) and (20c) which in cooperation with the sidewalls (28a) & (28b) of the movement grooves (25) & (25a), align the bended longitudinal profiles caused by the contact with a bended "sash" (3) and bended glazing (19). This bending is caused due to temperature difference of the interior with the exterior environment.

STATE OF THE ART

Over the last couple of years there were developed many semi-invisible or invisible combinations of thermal insulating profiles for sliding doors and windows, with acceptable application for the roof and vertical elements of the "frame". These innovations had some limitations such as: insufficient insulation of the hidden parts of the doors and windows, cold liquefaction zones in the visible part of the window, no possibility of extending, stabilizing and aligning the floor attached to the frame, lack of waterproofing, floors which were internally and externally not coplanar, no regards or taking into consideration people using wheelchair or in use of walking aid. Moreover these types of framing do not support easily replaced glazing but only via dismantling part of the floor. Furthermore, the complexity of the sliding mechanisms become dysfunctional over the years especially the rollers, as they are attached at the "frame" and not at the "sash". In addition to the above, the temperature difference between indoor and outdoor environment is not widely taken into consideration therefore the expansion and contraction of the elements used is not efficiently addressed, leading to non-operational curving of the profiles and to limited choices of glazing for the horizontal elements of the "sash". The aim of this invention is to provide a solution to the above mentioned issues.

DISCLOSURE

One of the advantages of this invention is that the combination of thermal insulating profiles of the lower part for sliding doors and windows is semi-invisible and enclosed in the structural components of the building, increasing the visibility and the luminosity of the Interiors. This invention allows elderly people, people with wheelchairs, people using a walking aid with reduced mobility, children to move without facing any protruding surfaces. Moreover, the movement of objects even if they are mounted on wheels or not, is not impaired. The support profiles (7a), (7b), (8a), (8b), (8c) are vertically adjusted on the "frame" (1) and integrate coplanar the internal and external floor for easy access of people or moving objects. The present invention achieves the optimization of the thickness of permissible vertical thermal insulation zone (27), as well as liquefaction zones are non-existent, as it is centered on the vertical axis (31) of the combination of the thermal insulating profiles "frame" (1), "added horizontal support" (2), "sash" (3). The grooves on the floor (25), (25a) that allow the movement of the "sash" (3) and "added horizontal support" (2), have the acceptable length and depth, but narrow width dimension (D), for aesthetic and safety reasons to avoid accidents. The invention configured in this way also provides glazing replacing without dismantling the floor as well as placing the "sash" (3) after the placement of the floor. The sliding rollers (22) are inside sockets (23) within "added horizontal support" (2) and protected from external factors such as chemical cleaning and resilient in time corrosion. Since the sliding rollers are inside these sockets (23) and due to the mirroring inclination of the seating points (24), the counterforces lead to stabilization of the support base (22a) as well as of all moving parts. Ball bearings (22b) have U-form grooves at the contact point (22d), cooperating with cylindrical stainless guide (6a), (6b), (6c), (6d), in order to avoid sideways movement due to wind. The "sash" (3) in this invention are designed that way that prohibit access to foreign objects, humidity or air to enter to the interiors due to quadruple zone of waterproofing (13a), (13b), (13c), (13d). Moreover the semi visible part of thermal insulating "sash" profile (3) according to clients' needs, can be covered by aluminum profile (4d), (4c). This extra aluminum profile that can be placed for aesthetic reasons optionally can be colored with electrostatic paint RAL. The current invention allows the "sash" (3) and the "added horizontal support" (2) to slide between them in order to avoid the "bimetallic strip phenomenon".

The wheels (20a), (20b) and (20c) which roll on the side walls (28a), (28b) of the movement grooves (25) & (25a) align bended profiles, therefore the sliding of the moving parts is unhindered. The current invention is compatible with all energy and security glazing types. BRIEF

DETAILED

The semi-invisible combination of thermal insulation profiles of the lower part of sliding doors and windows which allows the unhindered passage of people and objects above it, as a set, consists from three parts as below:

a) from at least one thermal insulating profile, firmly attached to the structural components of the building, which is called "frame" (1) The "frame" (1) is a thermal insulating profile, having at least one movement groove (34) which is firmly attached to the structural components of the building, is a constructed set of some aluminum profiles (la), (lb), (lc) and some polyamide profiles (Id), (le), (If), (lg) crimped, as indicated by European and global standards. At Figure 2 a two movement grooves (34) "frame" (1) is crimped as one profile. Moreover at the "frame" (1) there are adjusted as rails, two per movement groove (34), aluminum profiles (5a), (5b), (5c) and (5d) that are firmly attached to the "frame" (1), In addition to the above, the aluminum profiles (5a), (5b), (5c) and (5d) have embedded cylindrical stainless steel profiles (6a), (6b), (6c), (6d), in which the rollers (22) are sliding. At Figure 5 there can be seen a two movement grooves (34) "frame" (1), one with a fixed "sash" (3) and one movement groove with two rails from cylindrical stainless steel profiles. Spacer parts (9) of parallelepiped shape are adjusted, at the appropriate points of the "frame" (1), in order for the fixed profiles to be placed.

b) from at least one thermal insulating profile, parallel to the floor, made from PVC or from strengthened polyamide, which is called "sash" (3) and it is equipped with the appropriate U shaped channels (18) in order to receive thermal insulating panels or glazing (19). The bottom side of the "sash" (3) has concave sockets (26a) and projections (15b) in order to cooperate with the profile (4a), (4b), (4c) and (4d) and profile (2) respectively. In all figures except figure 7 and 9 the "sash" (3) can be seen as well as its collaboration with the other elements of this invention. The moving sash profiles as well as the fixed, are the same.

c) from at least one tubular thermal insulating profile (2) placed parallel to the floor, made from polyester or polyamide, which incorporate or not fiberglass produced with puitusion or extrusion method or an assembly of thermal insulating or not profiles, is called "added horizontal support" (2). Inside the cavities (33) of the tubular thermal insulating profile (2), materials such as polyurethane, Nanogel etc. can be used for the improvement of the coefficient of thermal transmittance. Alternatively inside these cavities reinforcement profiles can be used to improve the static and dynamic resistance of the profile. The "added horizontal support" (2) is machined (23) and (32), so that the rollers (22) and the wheels (20a), (20b) and (20c) to be placed. Setting of the wheels needs drilling at the "added horizontal Support" (2) in order to place their axis (21). At specially shaped cavities (30) of the "added horizontal support" (2) plugs are placed and the vertical elements of the "sash" (3) that surrounds the glazing (19) of the sliding door and window. The 2D and 3D Figures 2,3,8,9 and 10 show the machining and the positioning points.

Combination of the above thermal insulating profiles for sliding doors and windows is enclosed at the floor openings, allowing to at least one "sash" (3) and one "added horizontal support" (2) to slide. The visible elements above the floor, have dimension (D) less than 22mm.

The "added horizontal support" (2) attached to the "sash" (3) are two independent profiles that slide one on the other, contract and expand without the one loading the other caused by material and temperature difference. The wheels (20a), (20b), (20c) that are placed at the "added horizontal support" (2) corrects the curvature of the "sash" (3) and therefore helps to the functionality of movement. The part of the "added horizontal profile" (2) which is placed between the sidewalls (28a) and (28b) is narrower dimension (C) from the rest of the profile dimension (E). The narrow main body dimension (C) of the "added horizontal support" (2) allows the movement grooves (25a) on the floor to have width with (D) dimension less than 16 millimeters. Support profiles (7a), (7b) are screwed or riveted at the "frame" (1). Moreover the floor support profiles (8a), (8b), (8c), (8e), and (8f) are glued to the structural components and are placed at the sockets (14a), (14b).

At point number (10) glue hould be placed at the grooves.

The support profiles (8a), (8b), (8c) of the floor (12d), (12e), (12f) have angular extension (8d), (8e), (8f) which covers the sidewalls (28a) and (28b) of the grooves (25) and creates new sidewalls (25a) in order to provide uniformity and linear alignment. Figure 10, 11 show the application of the angular support profiles (8d), (8e) and (8f).
