Description

adjustable hinge

technical field

The present invention relates to a hinge for a door or other closure, in particular but not exclusively for a door which may be fixed to an existing frame, wall or other fixture. The hinge is used in particular in the installation of glass doors. Glass doors cannot be cut to size to fit irregularly shaped fixtures. While wooden doors can be planed to fit frames that are not perfectly vertical, glass doors cannot be altered after manufacture away from the assembly site.

Background technique

Previously known hinges provide multiple sheets of backing material which can be selectively removed to adjust the angle of the hinge relative to a fixture or relative to a door with which the hinge engages. This configuration is cumbersome and inefficient because the adjustment of the hinge may not be fine enough. Plates cannot be replaced once removed, making assembly irregular.

A glass door is pivotally mounted in a door frame with two or more hinges. However, it is important to have the glass panes aligned accurately with the door frame because when the glass panes are not aligned exactly with the frame, the glass door will not close completely. However, accurately fitting the glass panes in the door frame using the hinges can be difficult because the glass panes are often bulky and extremely heavy. Minor adjustments may be required to accurately align the glass pane with the frame. Conventional hinges for glass doors are complex to assemble and cannot be adjusted to align the glass panel with the door frame after the glass panel is mounted on the door frame. Therefore, the assembly of glass panels in the door frame using conventional hinges requires experienced fitters, or repeated assembly, disassembly and reassembly, to ensure accurate alignment. This makes assembly inconvenient, slow and expensive.

The hinge mandrel can be moved laterally relative to the installation body by using the adjustable screw. However, with previously known hinges it was not possible to achieve gimbal adjustment of several degrees of freedom by combining lateral and pivotal movements.

Contents of the invention

According to the invention, a hinge includes a mounting structure adapted to be secured to a fixture in use, the mounting structure having a mounting body;

a hinge leaf adapted to be secured in use to a door or other closure, the hinge leaf having a hinge body;

The hinge leaf and the hinge body can rotate around the hinge axis relative to the installation structure;

an aperture extending through the mounting body and the hinge body, the aperture being coaxial with the hinge axis;

a mandrel having a mandrel axis within the bore and having a pivot location on the mandrel axis;

wherein the radial dimension of the aperture is greater than a corresponding radial dimension of the mandrel such that the mandrel may be offset from the axis within the bore to adjust either or both of the location and orientation of the mandrel relative to the mounting body;

the mandrel has one or more joint surfaces;

The hinge or mounting body contains a plurality of clamping devices movable between an engaged position where the position of the mandrel is adjustable and a disengaged position where the clamping devices engage one or more a joint surface so that the mandrel is clamped and cannot move relative to the hinge body or the mounting body, respectively;

wherein the offset from the axis of the aperture may be at an angle, parallel or both; and wherein the pivot is located within the aperture of the mounting body; and

Wherein the clamping device includes a plurality of screws or other threaded parts.

Where hinges are used, for example with bolts or screws, the mounting structure may be secured to a wall, door frame or other fixture and the door is engaged and clamped by the hinge leaves. As an option, the mounting structure may be adapted to engage the edge of an adjacent door panel, for example it may include a clamp for securing the edge of the glass panel. The orientation of the door is adjustable and when the correct orientation has been achieved, the clamping means can be engaged to further prevent movement of the mandrel relative to the mounting body. In so adjusting, the weight of the door is supported, making assembly of the door easier, quicker and more precise than with existing hinge configurations.

The offset of the mandrel from the axis of the orifice may be angular, transverse or parallel or both. The mandrel rotates about the mandrel axis or about the hinge axis to achieve angular displacement. This angular displacement can adjust the initial position, the rest position or the closed position of the hinge leaf relative to the mounting structure. This allows adjustment to the correct orientation when the wall or door frame is not perpendicular to the ideal closed position of the door.

Displacement in the radial direction from the axis of the orifice enables lateral adjustment.

The hinge according to the invention can provide advantages that cannot be afforded by existing hinges.

The location or orientation of the mandrel relative to the movable hinge leaf or leaf can be adjusted in two or more directions or degrees of freedom selected from:

1. Lateral movement in one or more directions parallel to the hinge axis, for example, perpendicular or parallel to the hinge leaf or a direction both perpendicular and parallel to the hinge leaf.

2. Pivoting relative to a pivot point on the axis of the mandrel, e.g. at an intermediate point of the mandrel, the direction of the pivotal movement has a component selected from: towards the movable hinge leaf; away from the movable hinge leaf; Sideways with respect to the movable hinge; or universal movement in any direction in between. Pivoting may be about an intermediate point of the mandrel or any other pivot point chosen along the length between the ends of the mandrel.

3. Rotation of the mandrel about the mandrel axis in a clockwise or counterclockwise direction; or

4. Rotation of the mandrel about the mandrel axis in a clockwise or counterclockwise direction relative to the rest position of the mounting structure.

5. Combinations of all four cases above.

When assembling a hinge or pair of hinges, two or more degrees of freedom, eg, three or four degrees of freedom, can be achieved.

In an advantageous embodiment, during assembly or subsequent adjustment of a hinge mounted on a door, the orientation of the spindles of two or more hinges can be adjusted in two or more of the transverse and pivotal orientations of the spindles. where. The pivotal adjustment of the first hinge requires the second hinge of the same door to move both laterally and in the pivoting direction so that both hinges maintain a common hinge axis.

The pivoting movement may tilt the mandrel axis parallel or perpendicular to the hinge axis or at any intermediate angle and thus tilt the hinge leaf, door or door frame or mounting body.

In a preferred embodiment, the pivot is located within an aperture of the mounting body.

The clamping means may comprise a plurality of screws or bolts or other threaded elements. Preferably, three or more screws are used, arranged such that the screw axis intersects the mandrel axis at or adjacent to where the pivot is located.

The screw axes may be located on the equator about where the pivot is located, spaced equidistantly around where the pivot is located (e.g., at the midpoint of the mandrel), and may be, for example, offset by an angle of 90° to 120° from adjacent Screws to apply an effective and evenly distributed clamping force against movement on the mandrel from all directions.

The cylindrical engagement surface may have an axis coincident with or parallel to the spindle axis such that the engagement surface faces outwards from the spindle axis in a direction away from the mounting structure, for example in a direction parallel to the plane of the door in the closed position of the hinge. . In an embodiment, in the closed position, the two convex engagement surfaces may face outwards from the mandrel between the axis and the mounting structure or from the mandrel perpendicular to the plane of the door. Preferably, two convex surfaces and one cylindrical surface are used.

The screws or bolts may have pointed or flat ends to provide an effective frictional grip on the respective mating surfaces.

In one embodiment, a single mounting body is centrally located between two hinge bodies along the axis of the hinge. In use, the hinge body can be positioned above and below the mounting body along the axis.

In order to facilitate the rotation of the hinge body relative to the mandrel, bearings may be provided.

The spindle may be provided with a camming surface to engage a closure mechanism such as disclosed in WO2011/020630, the disclosure of which is incorporated by reference into this specification for all purposes.

The closing mechanism may include one or more spring-actuated pistons within the hinge body movable relative to the spindle, the one or more pistons being engaged by a cam surface to urge the hinge into the closed position.

In an embodiment, the mandrel may have a central portion including a joint surface and upper and lower cylindrical portions above and below the central portion, respectively.

As an option, the mandrel may have a cylindrical central portion and upper and lower portions respectively having joint surfaces. In this embodiment, an upper clamping device and a lower clamping device are provided. This can give a firmer grip on, for example, heavy doors. The central portion may contain one or two fastening or clamping cam surfaces.

The mandrel is tiltable or rotatable in a plane parallel to the plane of the door in the closed position, so that the upper or lower edge of the door can be tilted or moved upwards or downwards relative to the ground, as required. The mandrel may be tilted perpendicular to the plane of the closed door to tilt the top or bottom edge of the door inwardly or outwardly in the closed position.

Screws in the mounting body parallel to the plane of the closed door allow adjustment of the lateral position of the mandrel. It is possible to adjust where the corners are and to tighten the screws to the convex joint so that the mandrel maintains the required orientation relative to the vertical in a plane parallel to the plane of the closed door and fixture to which it is attached in use. angle.

The orifice may be cylindrical, which is circular in plan view. As an option, the aperture may be elongated, eg having a larger dimension in a direction perpendicular to the plane of the closed door than in a dimension parallel to the plane of the closed door. The aforementioned apertures, which are elliptical or oval in plan, may be used to provide a greater degree of forward and rearward tilting motion. In this configuration, the degree of mobility of the movement is greatest in a direction perpendicular to the plane of the closed door. This allows the angle of the hinged door to be tilted forward or backward when assembled.

The use of a hinge according to the invention has many advantages. After assembly, for example, after prolonged use, the orientation of the hinged and door to which the hinge is attached can be adjusted if the frame sinks or moves under the weight of the door. Unlike configurations in which the fill material is selectively removed from the plates, infinite fine adjustment is possible. Can have any degree of adjustment. Contact with the ground is avoided, therefore, no adjustable bottom plate is required. Assembly is quick and easy. Precise alignment can be achieved without employing experienced fitters or manipulating heavy and easily broken doors.

Detailed ways

1 and 2 show a first embodiment of the invention. The hinge includes a mounting structure (1) having screw holes (2) so that the door leaf plate can be fixed to a door frame, a wall or other fixtures by means of screws or bolts. The installation body (3) protrudes from the installation structure (1). The mounting body (3) has a vertically extending columnar opening (4). Three grub screws (5, 6, 7) are accommodated in threaded holes arranged at 90°, 180° and 270° respectively to the plane of the mounting structure. The mandrel comprises upper and lower cylindrical parts (10, 11) and an intermediate joint part (9) comprising two planar and cylindrical ends, as shown in Figure 16 .

Figure 3 shows a hinge body with a modified mandrel. The mandrel (8) comprises a generally cylindrical body having a central cylindrical portion (9) and upper and lower cylindrical portions (10, 11). The upper and lower parts have planar cam surfaces (12, 13) facing away from the hinge leaves and arranged to engage spring-driven closing and/or damping pistons, as disclosed in WO2011/020630, no matter from In that sense, the content disclosed in WO2011/020630 is incorporated in this specification by reference for all purposes.

The two hinge leaves (14, 15) cooperate to form a parallel side channel (16) that is sized to receive and engage a glass or other door panel (not shown).

The hinge body (17) integral with the hinge leaf (14) has an upper aperture (18) and a lower aperture (not visible) coaxially aligned with the aperture (4) of the mounting body. The apertures each have a larger diameter than the diameter or radial dimension of the mandrel (8) so that the mandrel can be moved transversely parallel to the axis and also deflected to a limited degree within the aperture relative to where the pivot is located . The pivot is located at the middle point of the mandrel along the mandrel axis and, in use, at the center of the mounting body. The location of the pivot can be in a plane perpendicular to the axis of the mandrel, in which plane the axes of the screws (5, 6 and 7) extend.

A pair of opposing convex surfaces (19, 20) (see Figure 17) are arranged to engage the screws (5, 7). The radius of this convex surface can be equal to the distance of the face (19, 20) from where the pivot is located, so that this face is always perpendicular to the screw (5, 7), regardless of the angle at which the mandrel is inclined. This ensures that the screw is securely engaged with the mandrel when the mandrel is assembled into the desired orientation.

Roller bearings (21, 22) allow the top and bottom of the mandrel to rotate within the upper and lower apertures (18) as the hinge pivots in use, preventing wear of the moving parts over prolonged use.

Figures 4 to 15 illustrate various orientations of the mandrel (8) relative to the mounting structure (1). The views in each of these figures include front side and isometric views of the assembly and plan views of the mount with and without the mandrel in the aperture, respectively.

In Figure 4, the mandrel is aligned with the vertical axis and is at a maximum distance from the mounting structure such that the hinge mounted door protrudes vertically the maximum distance from the hinge. This configuration is obtained by retracting the screw (6), allowing the screws (5 and 7) to protrude into the apertures, and then tightening the screw (6) to secure the mandrel.

Figure 5 shows the mandrel also in vertical orientation but at the shortest distance from the mounting structure. This configuration is obtained by extending the screw (6) into the aperture until the mandrel touches the opposite face of the aperture, then tightening the screws (5 and 7).

Figure 6 shows the mandrel arranged vertically on the right side of the aperture (as shown). This configuration is achieved by tightening the screws (6 and 7) followed by the screw (5).

Figure 7 corresponds to Figure 6 with the mandrel on the left side of the orifice.

Figure 8 shows the spindle rotating in a clockwise direction perpendicular to the plane of the door in the closed position. This configuration is achieved by tilting the mandrel and then firmly tightening the screws (7) (6) and then screw (5).

Figure 9 corresponds to Figure 8, wherein the mandrel is tilted in a counterclockwise direction, as shown.

Figure 10 shows that the upper portion of the mandrel is tilted backwards.

Figure 11 shows the upper portion of the mandrel tilted forward.

Figure 12 is a variant construction in which the orifice is oval to allow greater lateral movement of the mandrel. In plan view, the mandrel is shown to the right of the orifice.

Figure 13 corresponds to Figure 12 with the mandrel on the left side of the orifice.

Figure 14 shows a configuration in which the mandrel is tilted counterclockwise.

Figure 15 shows a similar configuration to Figure 14, where the mandrel is angled clockwise.

FIG. 16 shows perspective, elevation and cross-sectional views of the mandrel shown in FIG. 2 . The two sectional views show the engagement of the screws (5, 6 and 7) through the central portion (23) of the mandrel. The cross-sectional configuration of the central portion of the mandrel includes two parallel faces (28) with cylindrical ends (29). Parallel faces (28) are intended to engage screws (5, 7) to fix the mandrel in a desired angular and/or transverse orientation.

Figure 17 shows the mandrel of the embodiment shown in Figure 3, wherein the upper and lower cylindrical portions have planar cam surfaces to engage the closing pistons (30,31) as shown in Figures 18 and 19.

Figure 18 is an exploded view of a hinge according to the present invention comprising self-closing members. Upper and lower pistons (30, 31 ) driven by springs (32, 33) against the baffle (34) engage cam surfaces (12, 13) of the spindle (8). The pressure exerted by the pistons (30, 31) on the cam surfaces rotates the hinge to the closed position of the door provided with self-closing members. Bearing rings (51, 52) are arranged around the upper and lower ends of the mounting body (3).

Figure 19 shows a similar self-closing hinge in which ball bearings (35, 36) are provided in order to improve the free rotation of the hinge in use.

Figure 20 shows a perspective view of a modified hinge in which the mounting body (3) has two apertures (37, 38) extending towards the mounting structure (1). Pistons (39, 40) located in the bores are urged by springs (41, 42) into contact with the planar cam surface (50) of the mandrel. Engagement surfaces are provided at the upper and lower ends of the mandrel. The cylindrical engagement surface (43) and the two convex engagement surfaces (44) have a configuration similar to that disclosed above. Upper and lower screws (45, 46) secure the mandrel to the fixed location in the aperture in the hinge body. The location and orientation of the mandrel can be adjusted by adjusting the screws accordingly. Tilting the mandrel, rotating the mandrel, and moving the mandrel laterally can be accomplished. The hinge's resting, closed position can also be adjusted.
