Description

Technical Field

[0001] This invention relates to fittings for windows or doors. More specifically, this invention relates to fitting assemblies rotatably connected to a rotatable arm, the fitting assembly being insertable into a fitting slot in a window or door profile. Background Technology

[0002] Typically, windows are building components made of profiles, such as aluminum profiles. Window profiles are usually integrated into other building components, such as walls, roofs, or doors. Profiles are also used in building components other than windows, such as doors. Windows can be fixed windows or parts of windows, such as window sashes, that can move relative to each other or relative to a fixed frame. To enable this movement, window fittings are used for safety or other functional purposes. Window fittings include fitting assemblies that can be slidably or otherwise positioned in fitting slots provided within the window profile.

[0003] In many cases, the movement is hinge movement around the hinge axis. Therefore, it is necessary to be able to fasten the hinge arm to the fitting assembly, which is set in the profile during use.

[0004] A known example of such a fitting assembly is a fan blade housing that fits snugly into a fitting slot in the fan blade profile, thus securing it firmly to the profile, and a hinge arm that can be mounted on the fan blade housing in a manner that allows hinge movement.

[0005] Known methods for securing the hinge arm to the fan blade housing each have their own drawbacks, including examples described below.

[0006] The conventional method of mounting hinge pins utilizes rivet connections, where the head undergoes plastic deformation. To achieve this connection, space needs to be provided for the eccentrically moving rivet punch. This space can potentially weaken the fan blade housing.

[0007] - Another possibility is through a pressing operation. However, this would generate a large amount of internal stress in the fan blade housing, making the connection only able to withstand lower loads.

[0008] - Another possibility is a shaft with a flexible retaining ring. This would require a lot of space, possibly more than the space available for installing, for example, a concealed hinge arm. Summary of the Invention

[0009] The object of this invention is to provide an alternative solution for efficiently and effectively rotatably connecting a rotatable arm to an accessory assembly. Preferably, the connection is detachable and / or removable.

[0010] Another object of the present invention is to provide a solution for rotatably connecting a rotatable arm to an accessory assembly while remaining reliable under continuous load and preferably capable of maximizing load so that it can also be applied to situations with greater loads without deforming the assembly, for example, when the accessory assembly is inserted into the accessory slot of a large and / or heavy fan blade during use.

[0011] Another object of the present invention is to provide a solution for rotatably connecting a rotatable arm to an accessory assembly, such that the rotatable arm can be concealed within the profile during use.

[0012] In order to at least partially provide a solution to one or more of the aforementioned disadvantages and / or to meet one or more of the aforementioned objectives, the present invention provides an accessory comprising an accessory assembly having a body with a protruding portion and a channel opening; a rotatable arm having a shaft channel; and a shaft for rotatably connecting the rotatable arm to the accessory assembly, the shaft extending in a longitudinal direction (L) from an outer end to an inner end, wherein the shaft includes a widened head at the outer end, a radially projecting lip at or near the inner end, and a middle portion.

[0013] The fitting assembly can be attached to a fitting groove, which is provided in the window profile. Fitting grooves are known and typically formed by two upright parallel ribs of the profile, positioned a distance apart from each other, with their free edges curved toward each other to form two undercut longitudinal grooves. The fitting assembly can be slidably or otherwise, preferably adaptably, disposed in the fitting groove between the free edges. Typically, if the fitting assembly is slidable, the assembly has a lateral guide at one or both longitudinal edges, which engages with the corresponding undercut longitudinal groove or longitudinal groove of the fitting groove to slidably guide the fitting assembly into the fitting groove.

[0014] The main body of the accessory assembly may have opposing longitudinal edges, wherein the accessory assembly can be attached to an accessory slot, and the corresponding longitudinal edges laterally define the corresponding free edges of the accessory slot. The longitudinal edges may have regular or irregular shapes. Preferably, the longitudinal edges are adapted such that, in use, when the accessory assembly is positioned in the accessory slot, it contacts the corresponding free edges of the accessory slot at one or more points.

[0015] The protruding portion of the accessory component extends laterally outward from the main body, thereby selecting the position of the channel opening such that the channel opening partially overlaps laterally with the protruding portion and the main body. In other words, the channel opening is located at a longitudinal edge of the main body.

[0016] At the outer end of the channel opening, the channel opening of the fitting assembly includes a portion that is completely delimited in the lateral direction. Furthermore, the channel opening of the fitting assembly is configured such that the middle portion of the shaft fits into the channel opening, and the shaft channel of the rotatable arm is configured such that the middle portion of the shaft fits into the shaft channel, while the widened head cannot fit into the shaft channel.

[0017] In the assembled state of the accessory, a shaft is used, which is set in the channel opening and the shaft channel. The lip of the shaft is hooked on the body, and the arm is rotatably connected to the body of the accessory assembly, wherein the body and the arm are surrounded between the lip and the widened head of the shaft.

[0018] Preferably, the portion fully defined in the lateral direction of the channel opening of the accessory assembly and the shaft channel of the rotatable arm have a generally cylindrical shape, and the intermediate portion includes a generally cylindrical portion near the outer end of the shaft, which can be adapted to be disposed in the fully defined portion of the channel opening and the shaft channel.

[0019] In the construction according to the invention, the center of rotation of the shaft, and therefore the center of rotation of the arm relative to the fitting assembly, is located near or on the longitudinal side of the body, and in the case that the fitting assembly is mounted in the fitting groove of the profile, it is also located at or near the edge of the fitting groove. This means that the body of the fitting assembly has a cross-section in the transverse direction with little or no weakening, which can be selected to best fit between the edges of the fitting groove in the transverse direction, so that the strength of the profile can also be optimally utilized during use. For example, compared to conventional rivets on flanges, the applied tensile force is closer to the centerline of the body. Therefore, the torsional force is smaller.

[0020] The present invention also has the advantage that, using fitting components disposed in fitting slots in the profile, the rotatable arm can be installed on the profile, preferably on a window profile, in a non-invasive manner. Furthermore, the installation of the rotatable arm is very simple, the internal stress generated during assembly is very limited, and the structure according to the invention is very compact.

[0021] In the context of this invention, the term "rotatable arm" refers to an assembly that is, or can be, tiltably mounted on a fitting assembly that may be disposed in a fitting slot in a profile. The ultimate goal is to allow two or more building members to move relative to each other in a controlled manner. To this end, the invention, more specifically, allows the rotatable arm, fitting assembly, and hinge axis to form a direct hinge between two building members, one of which is connected to the rotatable arm, and the other (e.g., a window profile) is connected to the fitting assembly, such that the building members can tilt relative to each other. However, the invention can also be part of a larger system capable of allowing two or more building members to move relative to each other in a controlled manner. For example, the invention can be part of a four-bar linkage system, where the rotatable arm, fitting assembly, and hinge axis form one corner of the four-bar linkage. Another application of the invention can be a limit stay device, where, for example, the fitting assembly is attached to a first building member (e.g., a door, with the profile disposed in the door and the fitting assembly fitted within the profile), and the rotatable arm is attached to a second building member (e.g., a wall or door frame) via an actuator (e.g., a mechanical, pneumatic, or hydraulic spring).

[0022] In an embodiment of the invention, a lip recess is provided at the inner end of the channel opening of the accessory assembly, wherein the lip recess is configured to receive a lip.

[0023] Similarly, in embodiments of the invention, the channel opening of the body of the fitting assembly includes a portion that is partially open in the lateral direction, located between the fully defined portion in the lateral direction and the inner end of the channel opening. Preferably, the opening of the partially open portion is located on the radially opposite side of the lip recess. This allows the arm to be rotatably connected to the fitting assembly by placing the shaft in the shaft channel and subsequently in the channel opening until the radially protruding lip is located in the laterally partially open portion of the lateral channel and at the level of the lip recess. Subsequently, the lip can be positioned in the lip recess by rotating the shaft about its longitudinal axis. This also allows the shaft to be disassembled by loosening it if desired. To facilitate shaft rotation, the shaft may optionally be provided with a rotating recess located in the head or inner end, the rotating recess being configured for easy rotation of the shaft, for example, using a tool such as a screwdriver or a Torx key.

[0024] Preferably, the lip edge recess includes one or more protrusions configured to hold the lip edge securely in place within the lip edge recess, thereby preventing any unintentional rotation. Alternatively or additionally, the lip edge may be secured in place using adhesive or by a pressing operation.

[0025] Preferably, the dimensions of the lip recess and the radially projecting lip are aligned with each other, such that the radially projecting lip of the shaft fits flush with the lip recess. This allows for optimal use of the space in the fitting slot.

[0026] Similarly, in embodiments according to the invention, the middle portion of the shaft includes a narrow section. This narrow section, together with the portion of the channel opening of the fitting assembly (which is partially open in the transverse direction), allows the shaft to be easily (if suitable, tilted) inserted through the channel opening and the shaft opening, and subsequently rotated so that the lip hooks onto the body. Therefore, if desired, the shaft can be provided with a larger radially projecting lip. Preferably, the narrow section includes a substantially flat surface radially opposite to the projecting lip. This configuration ensures that, in the mounted state, the lip-bearing shaft hooks onto the body, and this substantially flat surface of the narrow section is substantially parallel to the nearby longitudinal edge of the fitting assembly body, and preferably does not project outwards or projects very little relative to said longitudinal edge. Therefore, in use, when the fitting assembly to which the rotatable arm is attached is placed in the fitting slot, this substantially flat surface is adjacent to the corresponding edge of the fitting slot. Thus, in use, said edge of the fitting slot prevents the shaft from tilting and / or rotating, which is beneficial for the strength of the connection. Optionally, the narrow section of the shaft can be provided with a housing surface located in an extension of the cylindrical portion of the shaft.

[0027] In another embodiment of the invention, the fitting assembly is a hinge housing that can be attached to a fitting slot in the window sash profile along the outer contour of the sash, and the rotatable arm is a hinge arm. Thus, for example, the fitting may include a main arm, an intermediate arm, and a frame fitting assembly having a frame body that can be attached along the inner contour of the window's fixed frame, wherein the main arm and intermediate arm are hinged to each other, wherein one end of the main arm is hinged to the frame body and the other end is hinged to the hinge housing, and wherein one end of the intermediate arm is hinged to the frame body and the other end is hinged to the hinge arm. The fitting can be configured such that in the closed position of the fitting, the main arm, intermediate arm, and hinge arm extend relative to each other in a substantially parallel manner, with the main arm and hinge arm positioned adjacent to each other. The advantage of this configuration is that, because the main arm and hinge arm are adjacent to each other in the closed position, this allows them to have maximum thickness within the limited space of the profile, making higher loads possible without the risk of deformation of the associated arms.

[0028] The present invention also relates to a window provided with the accessories or combinations thereof described in the foregoing embodiments.

[0029] The present invention also relates to a method for rotatably connecting a rotatable arm to an accessory assembly, comprising the following steps:

[0030] a) Provide an accessory as described in the previous embodiments or combinations thereof, the accessory having a rotatable arm, a shaft and a body;

[0031] b) Insert the inner end of the shaft through the shaft channel of the rotatable arm, and subsequently through the channel opening of the body, wherein preferably, a protruding lip is held along the opening side of a portion that partially opens in the transverse direction of the channel opening, and

[0032] c) By rotating the axis about the longitudinal direction so that the lip hooks onto the body, or if a lip recess is provided, the lip rotates in the lip recess, thereby rotatably connecting the rotatable arm to the body, wherein the body and the arm are surrounded between the lip and the widened head of the shaft.

[0033] In an embodiment of the present invention, the method further includes the following steps:

[0034] d) Insert the main body with the arm attached thereon into the fitting slot of the window profile, so that the main body and the rotatable arm can be hidden in the profile. Attached Figure Description

[0040] Figure 5A and 5B The views shown in Figure 4, which are partially set in the window profile, are perspective and sectional views, respectively.

[0041] Figure 6 A perspective view of an alternative embodiment of the shaft of the fitting according to the invention is shown;

[0042] Figure 7 A different perspective is shown of another alternative embodiment of the shaft of the accessory according to the invention. Detailed Implementation

[0043] The example shown in Figures 1 to 5 of the fitting according to the invention is a concealed hinge for rotating the sash of a window relative to a fixed frame. The fixed frame and the sash are constructed of profiles, such as aluminum, with fitting grooves on their inner and outer contours, respectively.

[0044] Concealed hinges refer to hinges integrated into the space between the sash and the fixed frame, or more specifically, hinges integrated into the space defined by the opposing walls of the frame and sash in the closed position of the window, all of which make the hinges invisible when the window is closed.

[0045] The hinge includes a hinge housing 1, a hinge arm 2 having a cylindrical shaft channel 15, and a hinge shaft 3 for rotatably connecting the hinge arm to the hinge housing. The hinge housing 1 is substantially L-shaped and includes an upwardly extending component 4 and a body 5, the component 4 having guides 6 at its opposing longitudinal edges, and the body 5 having opposing longitudinal edges 12.

[0046] The hinge housing 1 can be attached (as shown in Figure 5) to the fitting groove 7 of the profile 8 at the corner of the window sash. The fitting groove 7 is formed by two upright parallel ribs 9 of the profile, which are located at a certain distance from each other, and their free edges 10 are bent toward each other to form two undercut longitudinal grooves 11. To attach the hinge housing 1, the vertically upward component 4 is slid into the fitting groove 7 of the vertical profile 8, while the guide 6 is fitted into the undercut longitudinal groove. The vertical sliding movement continues until the body 5 is fitted into the fitting groove 7 of the horizontal profile 8, where the body contacts the bottom of the fitting groove 7 and its corresponding longitudinal edge 12 contacts the corresponding free edge 10; in other words, the body is enclosed in the lateral direction between the free edges 10 of the fitting groove 7. Note that the body 5 does not extend in the undercut longitudinal groove 11 of the fitting groove 7 of the horizontal profile 8.

[0047] The main body 5 of the hinge housing 1 includes a protrusion 13 and a channel opening 14. The protrusion 13 protrudes laterally outward from the main body 5 relative to a nearby longitudinal edge 12, wherein the channel opening partially overlaps laterally with the protrusion 13 and the main body 5. At the outer end 20 of the channel opening 14, the channel opening 14 of the main body 5 (as shown in the image) Figure 3(As shown) includes a cylindrical portion that is fully defined in the lateral direction, and a lip recess 16 is located in the body 5 at the inner end 21 of the channel opening. The channel opening 14 includes a portion 18 that is partially open in the lateral direction, located between the portion 17 that is fully defined in the lateral direction and the inner end 21 of the channel opening 14.

[0048] Hinge shaft 3 (e.g.) Figure 2 As shown, a hinge arm 2 is rotatably connected to a hinge housing 1, extending longitudinally (L) from an outer end 22 to an inner end 23. The hinge shaft 3 includes a widened head 24 at the outer end 22, a generally cylindrical portion 26 near the outer end, and a radially projecting lip 25 at the inner end. The hinge shaft 3 includes a narrow portion 27 comprising a housing surface located within an extension of the cylindrical portion 26 of the hinge shaft. The narrow portion 27 includes a generally flat surface 28 radially opposite the projecting lip 25. The flat surface 28 shown is generally parallel to the longitudinal direction of the hinge shaft 3, but may also be at an angle to the hinge shaft, for example, between -30° and 30°.

[0049] The method for rotatably connecting the hinge shaft 3 and the hinge housing 1 is very simple. Figures 1A to 1C The steps of the method are shown.

[0050] The hinge arm 2 and the body 5 are aligned relative to each other, such that the channel opening 14 and the shaft channel 15 overlap, as shown. Figure 1A As shown.

[0051] Subsequently, the inner end 23 of the hinge shaft 3 is inserted through the shaft channel 15 of the hinge arm 2 and then through the channel opening 14 of the body 5, wherein the protruding lip 25 is held along the opening side of the portion 18 of the channel opening, which is partially open in the lateral direction, thereby allowing the cylindrical portion 26 of the hinge shaft to overlap with the shaft channel 15 and the fully defined portion 17 in the lateral direction of the channel opening. If desired, the insertion can be at an angle depending on the size of the lip 25, and the hinge shaft can then be tilted such that the hinge shaft extends straight through the channel opening and the shaft channel, as... Figure 1B As shown.

[0052] Now, by applying a screwdriver to the rotating recess and subsequently rotating the hinge shaft 180° about the longitudinal direction, the lip 25 of the hinge shaft 3 can be positioned in the lip recess 16, allowing the lip to rotate within the lip recess 16, thereby rotatably connecting the hinge arm 2 and the body 5. The body 5 and the hinge arm 2 are surrounded between the lip 25 embedded in the lip recess 16 and the widened head 24 of the hinge shaft 3, as shown. Figure 1CAs shown. In this position, the flat surface 28 of the hinge shaft 3 is substantially parallel to the longitudinal edge 12 of the body 5. The lip recess 16 includes a protrusion 19 configured to hold the lip 25 in a position where the lip is surrounded within the lip recess 16, thereby preventing any unintentional rotation.

[0053] like Figure 4A , 4B As shown in Figures 4C, the hinges in the closed, 90° open, and 180° open positions also include a main arm 30, a middle arm 31, and a frame body 32. The frame body 32 can be attached to the frame profile along the inner contour of the window's fixed frame. The main arm 30 and the middle arm 31 are hinged to each other. One end of the main arm 30 is hinged to the frame body, and the other end is hinged to the hinge housing 1. One end of the middle arm 31 is hinged to the frame body 32, and the other end is hinged to the hinge arm 2. The hinge is configured such that in the closed position (e.g., ... Figure 5A As shown in Figure 4, the main arm 30, intermediate arm 31 and hinge arm 2 extend to each other substantially parallel to each other, with the main arm 30 and hinge arm 2 located adjacent to each other. This allows the hinge arm to have maximum thickness in the limited space of the profile, making higher loads possible without the risk of associated arm deformation.

[0054] Figure 6 and 7 An alternative example of the hinge shaft 3 according to the invention is shown. The alternative example shown is largely similar to the embodiment shown in Figures 1 to 5, with the same reference numerals indicating the same or similar components or features. Therefore, in the further description, the focus is mainly on the differences.

[0055] Figure 6 The hinge shaft 3 shown extends longitudinally (L) from the outer end 22 to the inner end 23. The hinge shaft 3 includes a widened head 24, a generally cylindrical portion 26, and a radially projecting lip 25. The hinge shaft 3 includes a narrow portion 27 having a generally flat surface 28 radially opposite to the projecting lip 25.

[0056] Figure 7 The hinge shaft 3 shown extends longitudinally (L) from the outer end 22 to the inner end 23. The hinge shaft 3 includes a widened head 24, a generally cylindrical portion 26, and a radially projecting lip 25. The hinge shaft 3 includes a narrow portion 27 having a generally flat surface 28 radially opposite the projecting lip 25. On the opposite side of the flat surface 28, a leveling member 33 is disposed in the hinge shaft 3, extending partially within the narrow portion 27 and the cylindrical portion 26.
