Provided is a door locking system including: a frame (10) including a hole (11) and a stopper hole (12), wherein the hole (11) is formed inside the frame (10), wherein a door glass (60) is fitted in the hole (11, wherein the stopper hole (12) is recessed from the hole (11) into a first sidewall of the frame (10); a captive bolt (20) inserted into the first sidewall of the frame (10) in a first direction toward the stopper hole (12); and a stopper (30) fitted in the stopper hole (12), wherein the second direction is perpendicular to the first direction.

Provided is a structure of a non-interference front-surface opening and closing-type frame, which is advantageous in that, since a cover frame can be conveniently coupled right beneath a fixing frame, assembly of the cover frame and the fixing frame is substantially facilitated, it becomes easier to prevent the cover frame from being separated from the fixing frame by an external impact, and the vertical width between the lower portion of a rotating shaft of the cover frame and the lower portion of a compression piece is substantially reduced, thereby realizing slimness.

The present invention relates to a structure of a non-interference front-surface opening/closing-type frame, and is advantageous in that, since a cover frame can be conveniently coupled right beneath a fixing frame, assembly of the cover frame and the fixing frame is substantially facilitated, it becomes easier to prevent the cover frame from being separated from the fixing frame by an external impact, and the vertical width between the lower portion of a rotating shaft of the cover frame and the lower portion of a compression piece is substantially reduced, thereby realizing slimness. The present invention is also advantageous in that: the cover frame can efficiently open/close the fixing frame without interference of the fixing frame; escapement of the rotating shaft from the shaft groove can be prevented while the cover frame opens/closes the fixing frame; there is no concern that an elastic member may act as an interfering element during assembly of the fixing frame and the cover frame; and it becomes easier to maintain the state in which the cover frame closes the fixing frame. The present invention is also advantageous in that, when the cover frame opens the fixing frame, the cover frame can open the fixing frame more easily with no concern that the cover frame may contact a structure, such as a building wall body, and be interfered with, thereby substantially facilitating extended application to metal furniture of industrial materials, such as picture frames and door frames, or construction window/door frames.

The profiled element (1) comprises: one main portion (2) defining a holding surface (2a) for a central panel (3) of a door/window (4), the main portion (2) being adapted to form a perimeter frame (5) of the door/window (4); one retaining portion (6) which defines an abutment surface (6a) of the central panel (3) and is adapted to fasten the central panel (3) to the perimeter frame (5); and non-removable connection means (7) which connect the main portion (2) to the retaining portion (6) and are adapted to allow the movement of the retaining portion (6) between a raised configuration, wherein it frees superiorly the holding surface (2a), and a retaining configuration, wherein it faces the holding surface (2a).

A self-locking support system includes a female profile having a first profile leg extending approximately orthogonally from a base, a first locking leg extending from the first profile leg, and a first tip extending from the first profile leg, wherein a gap is formed between the base and the first profile leg, and a first male profile having a fulcrum formed at an intersection of a second profile leg and a second locking leg, the second profile leg having a second tip extending therefrom. When the second locking leg is inserted into the gap, and a locking bead is positioned between the first and second tips, the first male profile is caused to rotate about the fulcrum and the first and second locking legs are caused to engage against each other.

The present invention is directed toward a window or door insulation system including an attachable trim strip, and a securable transparent sheet, to create a removable and auxiliary insulation sheet. The trim strip includes a base attachable to a surface, a cover pivotably connected to the base, and an interior strip pivotably connected to the cover and base. The cover includes a first wall, an intermediate wall transitioning from the first wall, and a second wall transitioning from the intermediate wall. The first wall is pivotably connected to a first side of the base so that the cover is configured to be an open position or a closed position. A gap is defined between the second wall of the cover and the second side of the base when in the closed position. The interior strip is configured to keep the cover opened or closed.

Provided is a system for anchoring building elements comprising a frame piece and an anchoring device connectable to the frame piece comprising an anchor that can be fixed in the frame piece and a gripper pivotably connected to the anchor, and where the anchor can be inserted into a channel running in the longitudinal direction of the frame piece, which is formed by two mutually opposite channel walls, a bottom segment and an opening mouthing in the upper side of the frame piece, wherein the anchor, in an inserted position in the channel, can be fixed in position by means of one or more locking means which fix the anchor against the bottom segment of the channel.
