Abstract
Description
[Technical field]
[0001]
[0001] The present disclosure relates generally to a door stop device, and more specifically to a door stop device for limiting the opening movement of a hinged door beyond a predetermined angle. [Background technology]
[0002]
[0002] This background description is provided generally for the purpose of providing a context for the present disclosure. Unless otherwise indicated herein, the material described in this section is not admitted, either expressly or impliedly, as prior art to this disclosure or the appended claims.
[0003]
[0003] Commercial aircraft are generally constructed from modular components, and their size, weight, and configuration are determined by many considerations, including fuselage dimensions, aesthetics, and safety considerations. Commercial aircraft typically include storage units for storing baggage and other items. Storage units can take a wide variety of forms, but storage units with swingable doors have been widely used in commercial aircraft and other applications for many years. Such storage units may be mounted along the ceiling and side walls of the aircraft's interior.
[0004]
[0004] Various types of swingable doors have been used for the assembly of storage units. Typically, the door is mounted on a hinge that is attached to the frame or support of the storage unit. The door may rotate about the hinge from an open position, extending at an angle from the frame that supports the door, to a closed position that is substantially flush with the frame that surrounds the door on four sides. For structural, aesthetic, or other reasons, continuous or "piano" hinges are traditionally used to support swingable doors on commercial aircraft. However, when the door is opened, the door (or door latch) may strike or crash into structures adjacent to the door (e.g., walls, door frames, trim, or other objects). Repeated impacts as a result of the impacts may damage the adjacent structures and / or the door.
[0005]
[0005] There are many different configurations or mechanisms used to act as door stops or bumpers to prevent damage to the door and / or adjacent structures (e.g., walls, door frames, trim, or other objects) that may occur when the door is fully opened. Door stops may be designed to stop or limit the opening of the door at a certain angle to prevent a collision between the door and the structure adjacent to the door. Typically, door stops are installed or attached to the door frame or wall and placed in a location such that if the door is opened widely, the door will collide with the door stop and not with the structure adjacent to the door. Door stops are often constructed from soft materials such as rubber or plastic and may absorb the force of the impact from the door when the door is opened to prevent the door and / or adjacent structures from being damaged. In other configurations, door stops may be attached to the exterior surface of the door and operate in substantially the same manner as the frame and wall mounted door stops described above.
[0006]
[0006] However, these conventional door stops have several disadvantages and / or problems. For example, the door stops may require a structure adjacent to the prefabricated door (e.g., a wall, door frame, trim, or other object) to accommodate the door stop, which may increase installation costs. The door stops may also be required to be secured to the adjacent structure with special mounting hardware and tools (e.g., special screws, washers, screwdrivers, etc.), which may be time-consuming due to the number of door stops to be installed. Thus, the door stops cannot be easily removed, replaced, and / or relocated. In addition, the structure for mounting the door stops may need to be sufficiently reinforced to support the door stops.
[0007]
[0007] Furthermore, when a door stop is subjected to continued use, the continued impact force of the door against the door stop may partially loosen or completely disconnect the door stop from the adjacent structure and / or change the orientation of the door stop. Loss or alteration of the door stop may render the door stop inoperable and / or result in a relatively ineffective door stop. Thus, conventional door stops may be ineffective and may lead to undesirable damage to the door and / or adjacent structure. Furthermore, these door stops may be constructed of numerous parts and may be costly, heavy, and unattractive. Thus, there is a need for a relatively inexpensive, lightweight, and reliable door stop for limiting the opening movement of a hinged door. Summary of the Invention
[0008]
[0008] The present application is directed to a door stop device for a hinged door. The door stop device may be used to limit the degree or range of rotation of the door in an opening direction. For example, the door stop device may limit the door from opening beyond a predefined or predetermined angle. As a result, the door stop device may prevent the door from swinging toward and colliding with or contacting an adjacent structure (e.g., a wall, door frame, trim, or other object), thereby avoiding a collision between the door and the adjacent structure that may cause undesired damage. Thus, the door stop device may protect the door and / or the adjacent structure from undesired forces and / or damage when the door is opened.
[0009]
[0009] The door stop device can be made for different types of door hinge configurations and easily sized to various lengths / heights. The door stop device can also stop the movement of the door at a desired position without contacting or applying pressure to adjacent structures. For example, the door stop device can be configured to engage or interconnect with the door hinge to prevent axial or rotational movement of the door stop device around the door hinge. As a result, the door stop device can maintain a substantially fixed position relative to the door hinge to stop the movement of the door without contacting adjacent structures. Thus, the door stop device can be configured to contact only the door hinge to limit the opening movement of the door.
[0010]
[0010] The door stop device can be made with various configurations and sized to restrict the door from opening to different desired angles. The door stop device can be of relatively simple construction and inexpensive to manufacture. For example, the door stop device can be made from a single piece of material that allows the door stop device to be long lasting and relatively trouble free in operation. The door stop device can also be relatively lightweight, compact, and aesthetically appealing to enhance the overall appearance of the door hinge. Furthermore, the door stop device can be pre-installed or pre-assembled on the door hinge, thereby reducing installation time. In addition, the door stop can be durable to absorb forces from impact with the door. For example, a bumper or protective member can be coupled to the door stop device to absorb forces that may result from contact with the door.
[0011] In one aspect, a door stop device is provided. The door stop device may be adapted to couple to a hinge pin of a door hinge to limit opening movement of the door. The door stop device may include a body member having a first end face and a second end face opposite and parallel to the first end face. The body member may also include a through opening extending between the first end face and the second end face, the through opening configured to receive a hinge pin of the door hinge. Additionally, the body member may include an abutment surface extending between the first end face and the second end face, the abutment surface configured to abut against the door hinge to maintain the body member in a substantially fixed position relative to the door hinge. Additionally, the body member may include a first side extending between the first end face and the second end face.
[0012] In another aspect, a door stop device for limiting opening movement of a door is provided. The door stop device may be configured to be coupled to a hinge pin of a door hinge. The door stop device may include a body member having a first end and a second opposite end. The body member may also include a through opening extending between the first end and the second opposite end, the through opening configured to receive the hinge pin of the door hinge. Additionally, the body member may include an engagement surface extending between the first end and the second opposite end, the engagement surface configured to engage the door hinge to maintain the body member in a substantially fixed orientation relative to the door hinge.

[0019]
[0035] The present application is directed to embodiments relating to a doorstop device for a hinged door. The doorstop device may be used to limit the degree or range of rotation of the door in an opening direction. For example, the doorstop device may limit the door from opening beyond a predefined or predetermined angle. As a result, the doorstop device may prevent the door from swinging toward and colliding with or contacting an adjacent structure (e.g., a wall, door frame, trim, or other object), thereby avoiding a collision between the door and the adjacent structure that may cause undesired damage. Thus, the doorstop device may protect the door and / or the adjacent structure from undesired forces and / or damage when the door is opened.
[0020]
[0036] The door stop device can also be made for different types of door hinge configurations and easily sized to various lengths / heights. The door stop device can also stop the movement of the door at a desired position without contacting or applying pressure to adjacent structures. For example, the door stop device can be configured to engage or interconnect with the door hinge to prevent axial or rotational movement of the door stop device around the door hinge. As a result, the door stop device can maintain a substantially fixed position relative to the door hinge to stop the movement of the door without contacting adjacent structures. Thus, the door stop device can be configured to contact only the door hinge to limit the opening movement of the door.
[0021]
[0037] The door stop device may be made in various configurations and sized to limit the movement of the door to open to different desired angles. For example, the door stop device may limit the opening of the door to an angle between 90 degrees and 140 degrees. The door stop device may be of relatively simple construction and inexpensive to manufacture. For example, the door stop device may be made from a single piece of material allowing the door stop device to be long lasting and relatively trouble free in operation. The door stop device may also be relatively lightweight, compact, and aesthetically appealing to enhance the overall appearance of the door hinge. Additionally, the door stop device may also be relatively easy to install and remove. For example, the door stop device may be pre-installed or pre-assembled on the door hinge, thereby reducing installation time. Additionally, the door stop device may be durable to absorb forces from door impacts. For example, a bumper or protective member may be coupled to the door stop device to absorb forces that may result from contact with the door.

[0043] As shown in Fig. 3, the door stop device 230 is coupled to the hinge 223 of the third door 218 of the second storage assembly 212 when the door is disposed in a closed position. Fig. 4 shows the door stop device 230 coupled to the hinge 223 of the third door 218 when the door is disposed in a fully open position limited by the door stop device 230. Additionally, each of the doors of the first storage assembly 210 and the second storage assembly 212 may include a latch 240 for securing the door in a closed position to facilitate opening and closing the door. The latch 240 may be located anywhere on the doors of the first storage assembly 210 and the second storage assembly 212 (e.g., operably coupled to the door).
[0028]
[0044] 5 and 6, a door stop device 500 for a hinged door is shown according to an exemplary embodiment. The door stop device 500 can be used to limit the degree or range of rotation of the door in the opening direction. For example, the door stop device 500 can limit the door from opening beyond a predefined or predetermined angle. As a result, the door stop device 500 can prevent the door from swinging toward and colliding or contacting an adjacent structure (e.g., a wall, door frame, trim, or other object), thereby avoiding a collision between the door and the adjacent structure that may cause undesired damage. Thus, the door stop device 500 can protect the door and / or the adjacent structure from undesired forces and / or damage when the door is opened.
[0029]
[0045] 5, the door stop device 500 may be formed as a single piece structure generally comprising a body member or structure 502. The door stop device 500 may have a generally or substantially triangular or wedge shape. It is envisioned that alternative embodiments of the door stop device 500 may have a variety of other geometric shapes, both regular and irregular (e.g., cylindrical or rectangular configurations). The door stop device 500 may be pre-installed or pre-assembled to a door hinge, thereby reducing installation time.
[0030]
[0046] The door stop device 500 may be of relatively simple construction and may be made from a single piece of lightweight material having any desired height or thickness. The door stop device 500 may be made from a number of materials, including but not limited to metal, rubber, ceramic, steel, aluminum, plastic (e.g., nylon, polyamide polyester, polyphenylene sulfide, polyethylene, or polypropylene), or any other suitable material or combination thereof. The door stop device 500 may be constructed using any suitable manufacturing process (e.g., injection molding and / or milling processes).

[0056] 13-15, a doorstop device 800 is shown coupled or attached to a hinge assembly, according to an exemplary embodiment. The doorstop device 800 is designed to limit the opening movement of a hinged door. The doorstop device 800 may in many respects correspond in construction and function to the doorstop device 700 of FIG. 7 previously described. Generally, components of the doorstop device 800 that correspond to components of the doorstop device 700 are indicated by similar reference numerals in the 800 series.
[0041]
[0057] As shown in FIG. 13, the door 830 is rotatably secured to a support or door frame 832 by a hinge assembly 834. The hinge assembly 834 may be a continuous hinge, a piano hinge, or any other suitable hinge. A trim or molding strip 836 (e.g., a vertical rubber strip) may be secured to the support 832 adjacent the door 830. The hinge assembly 834 may have a hinge plate 838 coupled to the support 832 and a hinge plate 840 coupled to the door 830, as shown in FIG. 14. The hinge assembly 834 may include an axially aligned hinge barrel 842. A hinge pin 844 may be positioned through the hinge barrel 842 to fix the hinge barrel 842 in a relative position and to allow for relative angular displacement. The door 830 may be rotatable about the axis of the hinge pin 844. Figure 14 shows the door stop device 800 attached to the hinge assembly 834 when the door 830 is in a closed position. Figure 15 shows the hinge assembly 834 with the door stop device 800 removed.
[0042]
[0058] The opening movement of the door 830 may be limited by the engagement between the doorstop device 800 and the door 830. For example, when the door 830 is opened, the door 830 rotates until the exterior surface of the door 830 contacts a surface of the doorstop device 800 or a bumper member of the doorstop device 800. Figure 13 shows the doorstop device 800 mounted on the hinge assembly 834 with the door 830 as open as the doorstop device 800 will allow. When the door 830 is stopped from opening, as described above, no portion of the doorstop device 800 contacts the trim 836 or the support 832.
[0043]
[0059] Referring to Figures 16-18, other embodiments of door stop devices for hinged doors are shown. Door stop devices can be made in various configurations to limit the opening movement of the door to different desired angles. For example, the door stop device can limit the opening of the door to any suitable angle. In some embodiments, the suitable angle can be between 90 degrees and 140 degrees. The door stop devices shown in Figures 16-18 can correspond in many respects in construction and function to the door stop device 500 of Figure 5 or the door stop device 700 of Figure 7 previously described. Generally, components of the door stop device 1600 of Figure 16 that correspond to components of the door stop device 700 are designated by similar reference numerals in the 1600 series.
[0044]
[0060] 16, the hinge engagement surface 1610 of the doorstop device 1600 may be oriented at a predetermined angle to engage or interconnect with a surface of a door hinge. Based on the orientation of the hinge engagement surface 1610, the doorstop device 1600 may have an angle θ between an imaginary line 1650 passing through a first side 1604 of the doorstop device 1600 and an imaginary line 1652 passing through the hinge engagement surface 1610 such that the opening of a hinged door may be limited to a desired angle. The doorstop device 1600 may limit the opening of the door to approximately 90 degrees.
[0045]
[0061] Fig. 17 illustrates a doorstop device 1700 for limiting the opening of a hinged door to 110 degrees. The doorstop device 1700 can be configured with a particular orientation relative to the door hinge to form a predetermined angle θ between a first side 1708A and a hinge engagement surface 1710. Fig. 18 illustrates a doorstop device for limiting the opening of a hinged door to 130 degrees based on the angle θ between a first side 1808A and a hinge engagement surface 1810.
[0046]
[0062] In summary, the present application relates to embodiments of a door stop device for a hinged door. The door stop device may restrict the door from opening beyond a predefined or predetermined angle. For example, the door stop device may be made in various configurations to restrict the door from opening to different desired angles. Furthermore, the door stop device may be configured to stop the movement of the door at a desired position without contacting or applying pressure to an adjacent structure. Thus, the door stop device may contact only the door hinge to restrict the opening movement of the door. As a result, the door stop device may prevent the door from swinging toward and colliding or contacting an adjacent structure (e.g., a wall, door frame, trim, or other object), thereby avoiding a collision between the door and the adjacent structure that may cause undesired damage. Thus, the door stop device may protect the door and / or the adjacent structure from undesired forces and / or damage when the door is opened.
