Description

Adjustable hinge and door assembly and window assembly comprising same

Technical Field

The present utility model relates to a hinge or a hinge for mounting a door or window leaf to a frame. In particular, the present utility model relates to a hinge for doors or windows of predominantly plastic construction, such as those formed of uPVC, and which allows for compression adjustment.

Background

Door leaves or sashes made of plastic (usually uPVC plastic) are often fitted to commercial and domestic buildings. One or more hinges are used to connect a door leaf or sash to a surrounding frame, thereby forming a door or window assembly. Such hinges are typically not individually customized to the particular frame and door or window sash dimensions of the customer. It is therefore important that a single hinge can be used on a variety of door or window assemblies. This is typically accomplished by allowing the hinge to adjust in three orthogonal linear directions; vertical, sideways (i.e. in the plane of the door sash when closed) and compressive (i.e. perpendicular to the plane of the door leaf or sash when closed). Once mounted to the frame and the door leaf or sash, the hinge may be adjusted to ensure that the door leaf or sash fits properly within the corresponding frame.

Compression adjustment of the hinge is critical because modern door devices comprise a seal that is compressed between the door leaf or sash and the surrounding frame when the door or window is closed. The properly compressed seal provides the necessary weather resistance to prevent any airflow and moisture penetration into the building.

In known door or window assemblies, the compression adjustment is controlled by rotation of an eccentric hinge pin mounted within the hinge. One problem with using an eccentric hinge pin is that its rotation will inevitably move the door or window sash in two dimensions, typically sideways and in compression. A side effect of trying to adjust the compressed position of the door leaf or sash is therefore that the lateral position is also affected. This is undesirable because subsequent lateral adjustments must be made to compensate for lateral displacement. This not only complicates the method of installing the hinge, but also makes it more difficult for the customer to ensure that the seals of the door or window assembly are properly compressed.

This background description is provided to generally present the context of the present disclosure. Unless otherwise indicated herein, the materials described in this section are neither explicitly nor implicitly admitted to be prior art to the present disclosure or the appended claims.

Disclosure of Invention

The present utility model seeks to solve or ameliorate one or more of the problems associated with adjustable hinges for windows and doors, or to provide a useful alternative.

According to a first aspect of the present utility model there is provided a hinge for mounting a door or window sash to a frame. The hinge may include a first portion for securing to a frame. The hinge may comprise a second portion for fixing to a door leaf or a window sash. The hinge may include a hinge pin. The hinge pin may define a hinge pin axis. The hinge pin may connect the first and second portions such that the first and second portions are pivotally movable relative to one another. The hinge may include a compression adjustment mechanism. The compression adjustment mechanism may be configured to move the hinge pin linearly relative to the first portion in a direction substantially perpendicular to the hinge pin axis.

The compression adjustment mechanism may be configured to move the hinge pin in the compression direction. Movement of the hinge pin may be configured to move the second portion linearly relative to the first portion. The compression direction may be perpendicular to the vertical direction and the lateral direction. The compression direction may be perpendicular to the hinge pin axis. The compression direction may be perpendicular to the plane of the door leaf or sash (when closed). The vertical and lateral directions may be parallel to the plane of the door leaf or sash (when closed). The vertical direction may be parallel to the hinge pin axis. The compression adjustment mechanism may be configured to move the hinge pin in the compression direction independent of both the vertical direction and the lateral direction.

Advantageously, the compression adjustment mechanism allows the hinge pin, the second part and/or the door leaf or sash to be moved in a compression direction relative to the first part and/or the frame. This enables the door leaf or sash to be fitted correctly within the frame. Proper fitting ensures that the seal between the door or window and the frame is sufficiently compressed to provide good weather resistance when the door or window is closed.

It is also advantageous for the compression adjustment mechanism to move the hinge pin (and thus the second part and/or the door leaf or sash) linearly in the compression direction independently of both the vertical direction and the lateral direction. This simplifies the method of installing and adjusting the hinge. The user can independently adjust the hinge in three separate directions (vertical, lateral and compressive). For example, when adjusting the hinge in the compression direction, the user does not have to perform additional hinge adjustments to compensate for any undesired displacement of the hinge pin, the second part and/or the door leaf or sash in a vertical or lateral direction relative to the first part.

The compression adjustment mechanism may be located at least partially within the first portion. For example, during use, the compression adjustment mechanism may be housed within the first portion.

The first portion may include a first housing. The first housing may define a first chamber. The first housing may include a first aperture. The first portion may optionally include a second housing. The second housing may define a second chamber. The second housing may include a second aperture. The hinge pin may extend through the first aperture and optionally through the second aperture.

The compression adjustment mechanism may be located within a first chamber and/or a second chamber defined by the first housing and/or the second housing.

The first hole may be formed at one side of the first housing. The first plate comprising the first aperture may form part of or be connected to the first housing. The first plate may form a closure on one side of the first chamber defined by the first housing. The second hole may be formed at one side of the second housing. The second plate comprising the second hole may form part of the second housing or be connected to the second housing. The second plate may form a closure on one side of the first chamber defined by the first housing. The first and second apertures may be aligned to form a hinge pin channel. The hinge pin may extend through the hinge pin channel. The hinge pin may be located at least partially within a first cavity defined by the first housing and optionally at least partially within a second cavity defined by the second housing.

The first and/or second holes may have a length in the compression direction. The first aperture and/or the second aperture may have a substantially oval, elliptical or rectangular shape. The hinge pin may have a substantially circular cross-section. The hinge pin may have a cross-section smaller than the dimensions of the first and/or second apertures such that the hinge pin is movable (e.g., linearly movable) within the first and/or second apertures.

The compression adjustment mechanism may be configured to move the hinge pin within the first aperture and/or the second aperture. The compression adjustment mechanism may be configured to move the hinge pin along the length of the first aperture and/or the second aperture.

The compression adjustment mechanism may include a first adjustment block. The first adjustment block may be connected to or integrally formed with the hinge pin. The compression adjustment mechanism may include a first adjustment pin. The first adjustment pin may be movably engaged within the first adjustment block. Movement of the first adjustment pin may move the first adjustment block and the hinge pin relative to the first portion.

The first adjustment block, which is formed integrally with the hinge pin, is advantageous in that both elements can be formed from a single molded piece. Thus simplifying the manufacture of the hinge pin and the first adjustment block.

The first adjustment pin may include a threaded portion. The first adjustment block may include a first threaded passage for mating with the threaded portion. The first adjustment pin may include a non-threaded portion. The non-threaded portion may have a non-circular cross-section. For example, the cross-section may be polygonal (e.g., square or hexagonal) and may have rounded corners.

Rotation of the first threaded portion within the first threaded passage of the first adjustment block may be configured to move the first adjustment block relative to the first portion, for example, in a compression direction. In one example, the first adjustment pin includes a head having a recess for receiving a tool (e.g., a screwdriver or allen wrench) for rotating the first adjustment pin within the first threaded passage.

Alternatively, other mechanisms may be used to move the first adjustment block and hinge pin in the compression direction. In one example, the first adjustment block may be moved using a rack and pinion type mechanism. The first adjustment block may include a rack. And rotation of the pinion may drive the first adjustment block in the compression direction. In another example, a cam and follower mechanism may be used. The first adjustment block may include a cam follower, and rotation of the cam may drive the follower and the first adjustment block in a compression direction.

The compression adjustment mechanism may also include a first nut/end clip (nut). The first nut may be configured to engage a side of the non-threaded portion of the first adjustment pin. The first nut may include an opening for receiving an end of the first adjustment pin. The nut may be resilient and/or flexible such that rotation of the pin within the opening is limited, but rotation is possible when torque is applied to the pin. The first nut is advantageous because it ensures that the first adjustment pin retains its orientation after adjustment (i.e. rotation) and prevents any undesired rotation over time.

The first nut may be made of a synthetic plastic material, such as nylon. Synthetic plastic materials are advantageous because they can elastically deform around the first adjustment pin during rotation. Synthetic plastic materials provide additional benefits in rust protection. Nylon is particularly popular due to its excellent self-lubricating properties.

The first adjustment block and/or the first adjustment pin may be located at least partially within a first cavity defined by the first housing. The first housing may include a first passageway for accessing and moving the first adjustment pin. The first passageway may include an opening in the body of the first housing.

The hinge may further include a first cover. The first cover may be located on the first housing to cover the first passageway during use. The first cover may be made of a corrosion resistant material, such as metal or hard plastic. The first cover may be removable, for example, to access and adjust the first adjustment pin. The first cover provides useful protection for the compression adjustment mechanism. In some embodiments, the first cover may prevent unauthorized users from accessing the compression adjustment mechanism. The first cover also conceals the compression adjustment mechanism, giving the hinge a more aesthetically pleasing appearance.

The compression adjustment mechanism may further include a second adjustment block. The second adjustment block may include an opening for receiving an end of the hinge pin therein. The compression adjustment mechanism may further include a second adjustment pin. The second adjustment pin may be movably (movably) engaged within the second adjustment block. Movement of the second adjustment pin can move the second adjustment block and the hinge pin relative to the first portion.

The second adjustment pin may be identical to the first adjustment pin described above. The second adjustment block may include a second threaded passage for mating with the second threaded portion. The second adjustment block and the second adjustment pin may operate in the same manner as the first adjustment block and pin described above.

The compression adjustment mechanism (e.g., the second adjustment block) may also include a block retainer. The block retainer may include a second nut/end clip similar to the first nut/end clip described above. The block holder may comprise a retaining element for engagement with the first portion. The retaining element may be configured to retain the mass retainer within the first portion of the hinge during use.

The retaining element may include a male portion (male portion). The first portion of the hinge may include a female portion (portion). The male portion may be configured to engage the female portion of the first portion during use. The male and female portions may include snap-fit joints. The snap-fit joint may comprise a cantilever, twist-on or annular snap-fit joint. The retaining element may comprise a clip or a hook.

The block holder may further comprise a metal plate. The metal plate may be configured to abut an end of the second adjustment pin. The metal plate may be configured to act on an end of the second adjustment pin when the second adjustment pin moves (e.g., rotates). Advantageously, the metal plate provides the second adjustment pin with an anti-wear surface against which to act, thereby providing additional structural integrity and allowing the second adjustment pin to reliably move the second adjustment block.

The second adjustment block may be at least partially located within a second cavity defined by the second housing. The second adjustment pin may be located at least partially within a second cavity defined by the second housing.

The block retainer may be configured to retain the second adjustment block and optionally the second adjustment pin within a second cavity defined by the second housing during use.

The second housing may include a second passageway for accessing and moving the second adjustment pin. The second passageway may include an opening in the body of the second housing. The hinge may further include a second cover. The second cover may be identical to the first cover described above.

The second portion may comprise a barrel. The barrel may include a channel for receiving the hinge pin such that the second portion is pivotally movable about the hinge pin axis relative to the hinge pin.

The cylindrical portion may be located between the first housing and the second housing. The cylindrical portion may be located between the first aperture and the second aperture. The first end of the cylindrical portion may be adjacent to the first aperture and the second end of the cylindrical portion may be adjacent to the second aperture. The channel of the barrel may have a substantially circular cross-section. The cross-section of the channel may be large enough to allow the hinge pin to pass through the channel. The hinge pin may be configured to extend through the first aperture, the channel of the cartridge, and the second aperture during use.

The second portion may also include a flag. The flag portion may be connected to the cylindrical portion or integrally formed with the cylindrical portion. The flag may extend perpendicular to the hinge pin axis. The flag may be connected to a door leaf or a window sash. For example, the flag may be connected to the door leaf or window sash using one or more fasteners. Alternatively, the flag may be attached to the door leaf or window sash using an adhesive.

According to a second aspect of the present utility model, there is provided a door or window assembly. The door or window assembly may comprise a door leaf or a window sash. The door leaf or window sash assembly may comprise a hinge as described herein.

According to a third aspect of the present utility model, there is provided a method of adjusting the position of a door or window sash relative to a frame using a hinge as described herein. The method may include securing the first portion to the frame. The method may comprise fixing the second part to the door leaf or sash. The method may include adjusting a compression adjustment mechanism. Adjusting the compression adjustment mechanism may move the hinge pin, the second portion, and the door leaf or sash linearly relative to the first portion in a direction substantially perpendicular to the hinge pin axis.

The first portion may be secured to the frame using one or more fasteners (e.g., screws or nails). Additionally or alternatively, the first portion may be secured to the frame using an adhesive. The second portion may be secured to the door leaf or sash using one or more fasteners (e.g. screws or nails). Additionally or alternatively, the second part may be secured to the door leaf or the window sash using an adhesive.

The compression adjustment mechanism may be adjusted by moving the first adjustment pin. For example, the compression adjustment mechanism may be adjusted by rotating the first adjustment pin. Moving the first adjustment pin may be configured to move the first adjustment block and the hinge pin relative to the first portion. The compression adjustment mechanism may be adjusted by moving the second adjustment pin. For example, the compression adjustment mechanism may be adjusted by rotating the second adjustment pin. Moving the second adjustment pin may be configured to move the second adjustment block and the hinge pin relative to the first portion.

According to a fourth aspect of the present utility model, a method of assembling a hinge is provided.

A method of assembling a hinge may include providing a first hinge portion, a second hinge portion, and a hinge pin. The first portion may comprise at least one chamber. The method may include connecting the first portion to the second portion with the hinge pin such that the first portion and the second portion are pivotally movable relative to one another and an end of the hinge pin extends into the cavity. The method may include inserting a block retainer into the cavity of the first portion to secure the end of the hinge pin within the cavity of the first portion.

The first portion may be adapted to be secured to a frame. The second part may be used for fixing to a door leaf or a window sash.

The hinge may include a compression adjustment mechanism as described above. The hinge may also include a second adjustment block as described above. The retainer block may form part of a compression adjustment mechanism.

The block holder may comprise a holding element. The first portion may include a retaining recess. The retaining element may be configured to engage with a retaining recess of the first portion. The retaining element may comprise a male connector, such as an arrow-shaped clip. The retaining recess may comprise a female connector. Inserting the block holder into the chamber having the first portion may include clamping the retaining element into the retaining recess.

The method of assembling the hinge may further include inserting a first adjustment block into the first housing of the first portion. The method may include subsequently inserting a retention block into the chamber to retain the first adjustment block within the chamber. The method of assembling the hinge may further include positioning the first cover on the first housing and optionally connecting the first cover to the first housing. The method may further include positioning a second cover over the second housing and optionally connecting the second cover to the second housing.

Advantageously, the method ensures that the hinge pin is securely fixed in the hinge assembly and does not accidentally fall out of the assembly during shipping, installation or use. If the hinge pin is accidentally displaced, the first portion of the hinge and the second portion of the hinge may separate or become misaligned.

It is also advantageous that assembling the hinge in this way allows for easier installation of the hinge. The hinge may be preassembled and provided to the user. The user can then attach the hinge to the frame and the door leaf or sash without having to use separate hinge parts to assemble the hinge. This simplifies the installation process for the user. Alternatively, the hinge may be provided as a kit of parts and installed in the field. The first and second portions may be connected to the door or window and frame, respectively, and quickly connected together using hinge pins and retainer blocks to complete the door or window assembly.

It will be appreciated that any one or more features from any aspect of the utility model may be combined with other features from any aspect of the utility model.

Detailed Description

The present utility model is illustrated in the various figures of the accompanying drawings, which are intended to be exemplary and not limiting, wherein like/similar reference numerals are intended to refer to like/similar or corresponding parts.

It is to be understood that the use of terms such as upper, lower, left, right, lateral, vertical, etc. are for descriptive purposes only to aid in understanding and, therefore, do not preclude additional orientations or configurations of the disclosed utility model.

Turning now to fig. 1, a perspective view of a hinge 1 is shown. The hinge 1 comprises a first part 2 and a second part 4. The first portion 2 includes a body 14, a first housing assembly 10 and a second housing assembly 12. The second portion 4 comprises a flag 6 and a barrel 8 between the first housing assembly 10 and the second housing assembly 12. The second part 4 is pivotally movable relative to the first part 2. The body 14 of the first part 2 may be fixed to a door frame and/or a window frame (not shown). The flag 6 of the second part 4 may be fixed to a door leaf and/or a window sash (not shown).

The hinge 1 is adjustable in three orthogonal linear directions: vertical Y, lateral X, and compression Z. The compression adjustment Z will be described in more detail with reference to fig. 3 to 6. The vertical adjustment Y will be described in more detail with reference to fig. 7 and 8. The lateral adjustment X will be described in more detail with reference to fig. 9.

Turning now to fig. 2, an exploded perspective view of the hinge 1 is shown. The flag 6 includes a fixing plate 16. The fixing plate 16 is integrally formed with the cylindrical portion 8. The flag 6 includes a flag cover 17 and a lateral adjustment mechanism (as shown in fig. 9). The barrel 8 includes a passage 20 therethrough, i.e. therethrough.

The first housing assembly 10 includes a first housing 40, a first orifice plate 44, and a first cover 28. The first housing 40 defines a first chamber 45. The first housing 40 includes a first passageway 42. The first passageway 42 is substantially circular and is located in a surface of the first housing 40. The first passageway 42 provides a passageway through the first housing 40 into the first chamber 45. The first orifice plate 44 includes a first orifice 46. The first hole 46 has a length in the compression direction Z. More specifically, the first aperture 46 has a substantially elliptical shape with its major axis extending in the compression direction Z.

The first housing 40 and the first orifice plate 44 are connected to the body 14. The first orifice plate 44 is located at one side of the first housing 40 so as to form a closure to a first chamber 45 defined by the first housing 40. The first orifice plate 44 may be integrally formed with the first housing 40 or connected to the first housing 40 so as to form a closure to one side of the first chamber 45 defined by the first housing 40. When assembled, the first cover 28 is disposed on the first housing 40 so as to cover the first passageway 42. The first cover 28 also conceals the first end of the body 14, as shown in fig. 1. The first cover 28 may be connected to the first housing 40 such that access to the first chamber 45 through the first passageway 42 is restricted during use. This may be beneficial because during use of the hinge 1, unauthorized parties cannot gain access or entry to the compression adjustment mechanism (discussed below). The first cover 28 also conceals the compression adjustment mechanism, giving the hinge 1 a more aesthetically pleasing appearance.

The second housing assembly 12 includes a second housing 52, a second orifice plate 48, and a second cover 74. The second housing 52 defines a second chamber 54. The second housing 52 includes a second passageway 50. The second passage 50 is substantially circular and is located in a surface of the second housing 52. The second passageway 50 provides a passageway through the second housing 52 into the second chamber 54. The second orifice plate 48 includes a second orifice (not shown). The second orifice plate 48 and the second orifice are identical to the first orifice plate 44 and the first orifice 46, respectively. The second aperture is aligned with the first aperture 46 to form an aperture channel extending in a vertical direction Y (in use) between the first and second housings 40, 52.

The second housing 52 and the second orifice plate 48 are connected to the body 14. The second orifice plate 48 is located on one side of the second housing 52, thereby forming a closure to a second chamber 54 defined by the second housing 52. The second orifice plate 48 may be coupled to the second housing 52 or integrally formed with the second housing 52 so as to form a closure on one side of the second chamber 54 defined by the second housing 52. When assembled, the second cover 74 is disposed on the second housing 52, thereby covering the second passageway 50. The second cover 74 also conceals the second end of the body 14. The second cover 74 may be connected to the second housing 52 to limit access to the second chamber 54 through the second passageway 50 during use. This may be beneficial because during use of the hinge 1, an unauthorized party may not gain access or entry to the compression adjustment mechanism (discussed below). The second cover 74 also conceals the compression adjustment mechanism, giving the hinge 1 a more aesthetically pleasing appearance.

The compression adjustment mechanism includes a first compression adjustment assembly 22 and a second compression adjustment assembly 66.

The first compression adjustment assembly 22 includes a first adjustment block 26, a first adjustment pin 30, and a first nut/end clip 34. The first adjustment pin 30 takes the form of a first screw comprising a first threaded portion 31 and a first end portion 33. The first end portion has a generally square cross-section. In particular, the first end portion has a square cross-section with rounded sides. The first adjustment block includes a first threaded passage 32. The first nut 34 includes a first nut opening 36 and is made of a synthetic plastic material, preferably nylon.

When assembled, the first adjustment pin 30 extends through the first threaded passage 32 and into a first nut opening 36 in the first nut 34. The first nut opening 36 has an approximately square cross-section with rounded sides. The first threaded passage 32 of the first adjustment block 26 cooperates with the threaded portion of the first adjustment pin 30 such that rotation of the first adjustment pin 30 translates into linear movement of the first adjustment block in the compression direction Z (as further described with reference to fig. 3-6). The first nut 34 engages the side of the first end portion 33 of the first adjustment pin 30, thereby limiting rotation of the first adjustment pin 30.

The use of the first nut 34 is advantageous because it ensures that the first adjustment pin 30 retains its orientation after adjustment (i.e., rotation), thereby preventing any undesired rotation over time. The manufacture of the first nut 34 from a synthetic plastics material is particularly advantageous in that it is capable of being elastically deformed during rotation of the first adjustment pin 30, thereby providing resistance to rotation.

When the hinge 1 is assembled, the first compression adjustment assembly 22 is located within the first chamber 45 defined by the first housing 40. The head of the first adjustment pin 30 is aligned with the first passageway 42 of the first housing 40. When assembled, the first trim pin 30 may be accessed through the first passageway 42. For example, a user may insert a tool through the first passageway 42 to rotate the first adjustment pin 30.

The second compression adjustment assembly 66 includes a second adjustment block 58, a second adjustment pin 56, and a block retainer 67. The second adjustment pin 56 takes the form of a second screw comprising a second threaded portion 57 and a second end portion 59. Second adjustment block 58 includes a second threaded passage 62 and an opening 60. The block holder 67 comprises a second nut/end clip 70 in the form of two parallel walls, a holding element 72, a plate groove 68 and a metal pad 64. The holding element 72 takes the form of an arrow-shaped clip. The retaining element 72 is integrally formed with the second nut 70 and the plate slot 68 (i.e., the retaining element 72, the nut 70 and the plate slot 68 are made from a single molded piece). The retaining member 72, the second nut 70 and the plate slot 68 are made of a synthetic plastic material, preferably nylon.

In the assembled position, the metal pad 64 is positioned in the plate slot 68. Thus, the metal pad is located below the two parallel walls of the second nut 70. The metal pad 64 is not permanently attached to the plate slot 68. Thus, if desired (i.e., if metal pad 64 is subject to wear and tear), metal pad 64 may be removed and replaced.

When assembled, the second adjustment pin 56 is configured to extend through the second threaded passage 62 and into the second nut 70. The end of the second trim pin 56 abuts the metal pad 64 within the plate slot 68.

The two parallel sides forming the second nut 70 engage the sides of the second end portion 59 of the second adjustment pin 56, thereby limiting rotation of the second adjustment pin 56. The use of the second nut 70 is advantageous because it ensures that the second adjustment pin 56 retains its orientation after adjustment (i.e., rotation). The second nut 70 maintains the second adjustment pin 56 in a selected orientation, thereby preventing any undesired rotation over time. The manufacture of the second nut 70 from a synthetic plastics material is particularly advantageous in that it is capable of deforming around the second end portion 59 during rotation of the second adjustment pin and then returning to its original shape after the second adjustment pin has been rotated to its final position.

The second threaded passage 62 of the second adjustment block 58 mates with the threaded portion of the second adjustment pin 56 such that rotation of the second adjustment pin 56 translates into linear movement of the second adjustment block 58 in the compression direction Z (as further described with reference to fig. 3-6). When the second adjustment pin 56 is rotated, its end abuts the metal pad 64.

The use of the metal pad 64 is necessary because the base of the second housing is susceptible to wear when the second adjustment pin 56 is rotated, which would otherwise abut the end of the second adjustment pin 56. Advantageously, metal pad 64 provides a counter surface for second adjustment pin 56 to act upon, thereby providing additional structural integrity and allowing second adjustment pin 56 to reliably move second adjustment block 58. The base of the first housing 40 is thicker and stronger than the base of the second housing 52 (because no arrangement of retainer blocks is required), and therefore it is not necessary to use another metal pad for the first adjustment pin.

When the hinge 1 is assembled, the second compression adjustment assembly 66 is located within the second chamber 54 defined by the second housing 52. The head of the second adjustment pin 56 is aligned with the second passage 50 of the second housing 52. In this manner, the second adjustment pin 56 may be accessed through the second passageway 50. For example, a user may insert a tool through the second passageway 50 to rotate the second adjustment pin 56. Second adjustment pin 56 and second adjustment block 58 are retained in second chamber 54 by block retainer 67. The block retainer 67 forms a barrier to abut the back face of the second adjustment block 58. Thus, the second adjustment block 58, including the second adjustment pin 56, cannot slide out of the second chamber 54. The block holder is held within the second chamber using a holding element 72. The holding element takes the form of an arrow-shaped clip. The arrow-shaped clips are configured to engage with corresponding female recesses (not shown) in the second chamber 54 of the second housing 52.

The hinge 1 further comprises a hinge pin 24. The hinge pin 24 defines a hinge pin axis, which is schematically represented by dashed arrow a. The hinge pin axis a is parallel to the vertical direction Y and perpendicular to the compression direction Z and the lateral direction X. The hinge pin 24 has a substantially circular cross section. The first end of the hinge pin 24 is connected to a first adjustment block 26.

When the hinge 1 is assembled, the hinge pin 24 is inserted through the first chamber 45, the first bore 46, the channel 20, the second bore (not shown), the second chamber 54, and into the opening 60 of the second adjustment block 58. The second end of the hinge pin 24 is retained in the opening 60 of the second adjustment block 58 such that the hinge pin 24 is fixed relative to the second adjustment block 58.

The second part 4 is pivotally movable relative to the first part 2 about a hinge pin, i.e. the hinge pin axis a. Since the first and second holes 46, not shown, have a length in the compression direction Z, the hinge pin 24 is movable (i.e., linearly movable) within the two holes in the compression direction. As will now be explained with reference to fig. 3-6, using the first compression adjustment assembly 22 and the second compression adjustment assembly 66, the hinge pin 24 is movable relative to the first portion 2 in a compression direction Z (i.e., in a direction perpendicular to the hinge pin axis a).

The body 14, first housing assembly 10 and second housing assembly 12 of fig. 3 and 5 have been transparent to illustrate the compression adjustment mechanism. Fig. 4 and 6 show end views of the hinge 1. The second cover 74 has been removed from the views of fig. 4 and 6 to illustrate the second compression adjustment assembly 66.

The compression adjustment mechanism is configured to move the hinge pin 24 linearly relative to the first portion 2 in a compression direction Z (i.e., a direction substantially perpendicular to the hinge pin axis a). The compression adjustment mechanism moves the hinge pin 24 between a minimum compression position (as shown in fig. 3 and 4) and a maximum compression position (as shown in fig. 5 and 6).

In fig. 3 and 4, the spacing between the centers of the cylindrical portions 8 in the first and second portions 2, 4 in the compression direction Z is denoted by a distance a. The distance a is indicated by double headed arrows in fig. 3. When the hinge pin 24 is in the minimum compressed position, a maximum spacing in the compression direction Z between the first portion 2 and the center of the cylindrical portion 8 is achieved.

In fig. 5 and 6, the hinge pin 24 is in a maximally compressed position, in which the separation between the first part 2 and the second part 4 in the compression direction Z is indicated by a distance b. When the hinge pin 24 is in the maximum compression position, a minimum spacing between the first portion 2 and the cylindrical portion 4 in the compression direction Z is achieved.

The compression adjustment mechanism is used to move the hinge pin 24 from the minimum compression position to the maximum compression position. The first and second covers 28 and 74 are removed from the first and second housings 40 and 52, respectively. The first trim pin 30 is accessible through a first passageway 42. The first adjustment pin 30 is rotatable (i.e., using a tool) to move the first adjustment block 26 linearly in the compression direction Z relative to the first portion 2. Since the hinge pin 24 is connected to the first adjustment block 26, the hinge pin 24 moves with the first adjustment block in the compression direction Z. The second adjustment pin 56 is accessible through the second passageway 50 and is rotatable (i.e., using a tool) to linearly move the second adjustment block 58 in the compression direction Z relative to the first portion 2. The second end of the hinge pin 24 is retained in the opening 60 of the second adjustment block. Thus, movement of the second adjustment block 58 moves the hinge pin in the compression direction Z.

Simultaneous or successive rotation of the first adjustment pin 30 and the second adjustment pin 56 linearly drives the hinge pin 24 in the compression direction Z. Since the second part 4 is pivotally connected to the hinge pin 24, movement of the hinge pin 24 also moves the second part 4 relative to the first part 2 in the compression direction Z. After adjustment, the first and second covers 28, 74 may be positioned over the first and second housings 40, 52.

Advantageously, the compression adjustment mechanism allows the hinge pin 24, the second part 4, and the door leaf or sash (not shown) to be moved in a compression direction relative to the first part 2 and the frame (not shown), allowing the door leaf or sash to be properly fitted within the frame. Proper fitting ensures that the seal between the door or window and the frame is sufficiently compressed to provide good weather resistance when the door or window is closed.

It is also advantageous for the compression adjustment mechanism to move the hinge pin 24 (and thus the second part 4 and the door leaf or sash) linearly in the compression direction Z independently of both the vertical Y-direction and the lateral X-direction. This simplifies the method of mounting and adjusting the hinge 1, since it is not necessary to adjust the position of the hinge to compensate for any undesired displacement in the vertical Y-direction and the lateral X-direction.

Vertical adjustment mechanism and lateral adjustment mechanism

Fig. 7 and 8 show exploded perspective views of the vertical adjustment mechanism of the hinge 1. The vertical adjustment mechanism includes a fixed block 80, a vertical adjustment screw 70, and a vertical adjustment channel 100 in the body 14 of the hinge 1.

The vertical adjustment screw 70 includes a threaded portion 200a and has an end with a flat surface 71. The first portion 2 includes a screw channel 202 extending to the vertical adjustment channel 100 and includes a threaded portion 200b, with the vertical adjustment screw 70 engaging the threaded portion 200 b. The vertical adjustment channel 100 includes a first rail 102a and a second rail 102b on the inner wall of the body 14. The fixed block 80 has a top surface 91 and three frame fastener holes 82, 84, 86, and two rods 88 and 90. The fixed block also includes a first recess channel (not shown) and a second recess channel 98b for engaging the first rail 102a and the second rail 102b.

During installation, the securing blocks 80 are secured to the door or window frame with mechanical fasteners (e.g., screws). Subsequently, the body 14 of the first part 2 slides on the fixed block 80. The flat surface 71 of the vertical adjustment screw 70 abuts the top surface 91 of the fixed block 80. By rotating the vertical adjustment screw 70, the hinge 1 can be moved in the vertical direction Y with respect to the fixed block 80 (and thus with respect to the door or window frame).

Fig. 9 shows an exploded perspective view of the lateral adjustment mechanism 7 of the hinge 1, said lateral adjustment mechanism 7 comprising a lateral adjustment screw 320, a fixing block 302, a fixing screw 310 and a lateral adjustment block 316. The fixed block 302 includes a receiving channel 304, six fastener holes (one of which is labeled 306), and a threaded passage 308. The lateral adjustment block 316 has a flared (flat) base and is substantially rectangular parallelepiped in shape. The lateral adjustment block 316 includes a threaded opening 314.

The lateral adjustment mechanism 7 is mounted on a fixed plate 16. The mounting plate 16 includes two parallel fastener slots 318a, 318b, a lateral adjustment block slot (not shown), and a set screw slot 312. During assembly, the lateral adjustment block 316 is inserted through a lateral adjustment block slot in the fixed plate 16. The lateral adjustment screw 320 is driven through the receiving channel 304 of the fixed block 302 into the threaded opening 314 of the lateral adjustment block 316. The set screw 310 is inserted into the threaded passage 308 of the fixed block 302 through the set screw slot 312. Lateral adjustment mechanism 7 and securing plate 16 are attached to a door leaf or window sash (not shown) using mechanical fasteners (e.g., screws) that pass through six fastener holes 306 and parallel fastener slots 318a, 318b into the door leaf or window sash. During use, the flag cover 17 conceals the lateral adjustment mechanism 7.

The lateral adjustment mechanism 7 is configured to move the door or window sash in a lateral direction X relative to the first part 2 by rotating a lateral adjustment screw 320 within the threaded opening 314 of the lateral adjustment block 316. Once the lateral adjustment mechanism 7 is adjusted, the set screw 310 is tightened in the threaded passage 308 of the fixed block 302 to fix the fixed block 302 relative to the fixed plate 16.
