A hinge mounting structure is provided whose appearance can be improved. In a hinge mounting structure including a hinge (1) having a first piece (3) and a second piece (4) that are coupled together via a shaft (2) in such a manner as to be rotatable relative to each other, the first piece (3) being mounted on a side jamb (6), the second piece (4) being mounted on a door (5), the side jamb (6) is provided with a protruding portion (8) protruding forward of a wall surface, and a center (C) of the shaft (2) is placed backward of a front surface line (X) of the protruding portion (8) of the side jamb (6).

A hinge is provided, which comprises: at least one hinge pin defining a hinge axis in a first dimension; a hinge leaf; a housing comprising at least one recess for receiving a portion of the hinge leaf; and at least one user adjustable fastener arranged to enable user adjustment of the positioning of the hinge leaf within the at least one recess in a second dimension, wherein the second dimension is orthogonal to the first dimension.

Provided herein is a security door system having a door that includes a door frame comprising elongate door frame members, each having a first holding channel formed therein, and a clamping portion spaced from the first holding channel. The door further includes a mesh covering an opening enclosed by the frame. In addition to the above, the security door system includes a wall frame comprising elongate wall frame members operably coupled to the door frame by one or more hinge members, the hinge members facilitating pivotable movement of the door between open and closed positions and one or a plurality of security members configured to prevent or inhibit levering of the door relative to the wall frame.

A door hinge includes a door flange. The door flange includes a first-cylindrical portion. The first-cylindrical portion segmented and having an axially vectored borehole therethrough. The door hinge includes a frame flange. The frame flange including a second-cylindrical portion. The second-cylindrical portion segmented and having a corresponding axially vectored borehole therethrough. The first-cylindrical portion and second-cylindrical portion are configured to engage when their respective boreholes are coaxial. A plurality of apertures are disposed on the door flange and the frame flange. A plurality of plugs are included with the door hinge. Each of the plurality of plugs are sized and dimensioned to close at least one of the plurality of apertures. The door hinge is useful for attaching a door to a door frame.

In a invisible hidden door hinge (1), a first connecting body (2a) and a second connecting body (2b) are connected together by an articulation device (3) which allows the relative movement between a condition of opening and a closed condition in which the first (2a) and the second (2b) connecting body define a seat in which the articulation device (3) is enclosed. At least one of the connection bodies (2a, 2b) comprises a support structure (4a, 4b) shaped from a respective single metal sheet in a single concave piece having concavity facing a direction opposite to the depth direction (X1, X2) of the connecting body (2a, 2b) and defined by a bottom (42a, 42b) of the support structure (4a, 4b) and by side walls (43a, 43b) of the support structure (4a, 4b) that realize a continuous peripheral edge of the bottom (42a, 42b), joined to the bottom (42a, 42b) without interruption of the material of which said single metal sheet consists of and completely surrounding the bottom (42a, 42b) according to a closed curve around the depth direction (X1, X2) of the connecting body (2a, 2b).

A hinge is provided, which comprises: at least one hinge pin defining a hinge axis in a first dimension; a hinge leaf; a housing comprising at least one recess for receiving a portion of the hinge leaf; and at least one user adjustable fastener arranged to enable user adjustment of the positioning of the hinge leaf within the at least one recess in a second dimension, wherein the second dimension is orthogonal to the first dimension.

A hinge mounting structure is provided whose appearance can be improved. In a hinge mounting structure including a hinge (1) having a first piece (3) and a second piece (4) that are coupled together via a shaft (2) in such a manner as to be rotatable relative to each other, the first piece (3) being mounted on a side jamb (6), the second piece (4) being mounted on a door (5), the side jamb (6) is provided with a protruding portion (8) protruding forward of a wall surface, and a center (C) of the shaft (2) is placed backward of a front surface line (X) of the protruding portion (8) of the side jamb (6).

A hinge cover can be removably attachable to a hinge and include a snap on feature comprising a cylindrically shaped inner surface with a c-shaped cross-section, the c-shaped cross-section comprising an opening and a top portion opposite the opening configured to be releasably coupled to a hinge without adhesive, screws, or nails. The hinge cover can further include a deflecting feature, the deflecting feature further including a width extending in a direction of an axis of the cylindrically shaped inner surface of the snap on feature. The hinge cover can include a first ramp portion sloping away from the top of the snap on feature in a first direction. The hinge cover can include a second ramp portion sloping away from the top of the snap on feature in a second direction opposite the first direction.

A door hinge having two hinge leaves joined together at a knuckle defining a hinge axis about which the leaves are relatively pivotal and top and bottom sheet-metal parts forming a housing surrounding one of the hinge leaves. Two rotatable adjustment spindles are each journaled in the housing, rotatable about respective axes extending in a first direction perpendicular to the hinge axis, and operatively threadedly connected to the one leaf so that rotation of the spindles moves the one leaf in a first direction perpendicular to the hinge axis. A base plate between the parts is formed with respective threaded hole receiving the spindles, the base plate being secured to the one leaf for movement of the one leaf in a second direction perpendicular to the first direction relative to the base plate.
