Description

Technical Field

[0001] This disclosure relates to frame attachment components and frames including such frame attachment components, and more specifically, to means and components for attaching hollow frame components to other frame components to form a frame structure. Background Technology

[0002] A frame is a structure or structural system used to support other components of a physical device, such as an appliance, system, household appliance, vehicle, or building. Frames are composed of various components and parts and are typically used in a variety of applications across multiple industries. Certain frame types, materials, and components may be better suited to certain applications than others. For example, in applications such as vehicles and household appliances, a frame may consist of metal frame members fastened by fasteners such as nuts, bolts, and screws. In some applications, frame members may be attached in other ways, such as by adhesives or attachment processes (e.g., welding). Regardless of the application, the attachment between the various frame members affects the frame's function and performance in its intended application. The selection of the method or device for attaching the various frame components involves cost and design considerations.

[0003] In some applications, hollow components are used as frame members. Depending on the intended application of the frame, hollow frame members offer the advantage of providing the necessary shape and strength at a relatively lower cost and weight compared to solid frame members of the same size and shape. However, due to the nature of hollow frame members, which may include one or more open ends, the options for securing other frame members to them are more limited.

[0004] Solutions for attaching hollow frame components to form a frame typically involve some type of material attachment. For example, one solution is to directly attach at least some components to other frame components, such as by directly welding, soldering, or pressing metal hollow frame components to other frame components, and by directly attaching other attachment devices to the ends of the hollow frame components. (Reference) Figure 1 , Figure 1 This is a three-dimensional cross-sectional view of an existing solution for attaching hollow frame members to other frame members. In some applications, such as... Figure 1 As shown, the hollow frame component 10 is attached by physically or chemically attaching one or more first fasteners 12 to the open ends 14a, 14b of the hollow frame component 10. The physical or chemical attachment of the first fasteners 12 to the open ends 14a, 14b is typically achieved by welding or pressing. Figure 1As shown, one or more first fasteners 12 provide mating portions that can engage with other fasteners, such as one or more fasteners 16. Figure 1 In the example shown, the first fastener 12 is a nut and the second fastener 16 is a bolt or screw. This configuration allows other frame members 18 to be attached to the hollow frame component 10 by mechanically fastening the second fastener 16 through a portion of the other frame member 18 to the first fastener 12 welded to the open ends 14a, 14b. However, unless operated properly, attachments achieved through physical and chemical attachment processes may not be optimal and / or may weaken over time, potentially leading to attachment failure, which reduces the strength, integrity, and reliability of the frame. Furthermore, any attachment solution requiring attachment also incurs additional time and cost associated with additional manufacturing processes. Utility Model Content

[0035] Non-limiting embodiments of this disclosure generally relate to frame attachment assemblies that may include a hollow element and a support configured to be inserted into the hollow element. The support may include: an elongated body extending between a first end and a second end of the support; a first plate-like element positioned at the first end of the support, the first plate-like element having an aperture for receiving a fastener; and a second plate-like element positioned at the second end of the support, the second plate-like element having an aperture for receiving a fastener. When the support is inserted into the hollow element, the support may be configured to secure the hollow element between the first frame member and the second frame member by securing the first plate-like element to a first frame member by means of a first fastener and by means of a second plate-like element to a second frame member.

[0036] Non-limiting and exemplary embodiments of apparatus, components, and methods for attaching hollow frame components to other frame components according to the present disclosure will now be described with reference to the accompanying drawings, in which corresponding reference numerals indicate corresponding parts.

[0037] Now for reference Figures 2A to 2C , Figures 2A to 2C This is a perspective view of a non-limiting embodiment of the frame attachment component 100 according to the present disclosure. Figure 2AAs shown, the frame attachment assembly 100 may include a hollow element 102 and a support 104. The support 104 may be configured to insert into the hollow element 102. In some exemplary embodiments, the hollow element 102 may be a tubular member, such as a tubular length of material used as a structural member in the frame (e.g., plastic, metal, ceramic, carbon fiber, or wood). In some non-limiting embodiments, the hollow element 102 may include an elongated hollow body 106 extending between a first end 108 and a second end 110 of the hollow element 102. Both the first end 108 and the second end 110 may be open, or, in some non-limiting embodiments, one of the first end 108 and the second end 110 may be at least partially closed via an integral or removable end cap.

[0038] like Figures 2A to 2C Further examples are shown and can be found in other references. Figure 3A The support 104 may include a first plate-like element 112, a second plate-like element 114, and an elongated body 116 extending between a first end 118 and a second end 120 of the support 104. The first plate-like element 112 may be positioned at the first end 118 of the support 104, and the second plate-like element 114 may be positioned at the second end 120 of the support 104. The first plate-like element 112 and / or the second plate-like element 114 may be rigidly connected (including by an integral connection) to the elongated body 116 such that the first plate-like element 112 and / or the second plate-like element 114 are immovable relative to the elongated body 116 (e.g., non-pivotable or non-rotatable). Each of the first plate-like element 112 and the second plate-like element 114 may include a means for receiving fasteners (e.g., Figures 5A to 6 The holes or openings shown and described below in the fasteners 558a, 558b. For example, as Figures 2A to 2C as well as Figures 3A to 3C As shown, the first plate-shaped element 112 may include a first orifice 122, and the second plate-shaped element 114 may include a second orifice 124.

[0039] In some non-limiting embodiments, the first aperture 122 and the second aperture 124 may be configured to receive fasteners via threaded engagements. For example, the first aperture 122 and the second aperture 124 may be threaded and may be configured to receive threaded fasteners such as bolts, screws, etc. In some non-limiting embodiments, the first aperture 122 and the second aperture 124 may be unthreaded but may be configured to receive fasteners. For example, the first aperture 122 and the second aperture 124 may be suitably sized to receive self-tapping or self-drilling fasteners, such as sheet metal screws. In other embodiments, the first plate element 112 and the second plate element 114 may not include apertures, but may instead have sufficiently thin or weakened areas on their surfaces (including areas weakened by, for example, semi-shearing) such that these areas can be penetrated by fasteners such as nails, bolts, screws, etc.

[0040] Continue to refer to Figures 2A to 2C The support 104 can be inserted into the hollow element 102. This can be done by inserting the support 104 into the open end (e.g., the first end 108) of the hollow element 102 such that all or substantially all of the support 104 is accommodated within the hollow element 102. In some non-limiting embodiments, the second plate-like element 114 has an external dimension (e.g., perimeter) smaller than the internal dimension (e.g., perimeter) of the hollow element 102 to allow the second plate-like element 114 to slide smoothly through the hollow element 102. As will be further described below, the first plate-like element 112 may have an outer perimeter (or at least a portion of its outer perimeter) larger than the inner perimeter of the hollow element 102 to prevent the first plate-like element 112 from being fully inserted into the hollow element 102, thereby preventing the support 104 from sliding completely through the hollow element 102. In some non-limiting embodiments, the second end 110 of the hollow element 102 may include an end cap that at least partially covers the second end 110. In this embodiment, when the bracket 104 is inserted into the hollow element 102, the second plate-shaped element 114 can come into contact with the end cap to prevent further movement of the bracket 104.

[0041] Now for reference Figures 3A to 3C , Figures 3A to 3C These are perspective and side views of a non-limiting embodiment of the support 104 of the frame attachment assembly 100 according to this disclosure. Figure 3A As shown, the support 104 may include an elongated body 116 extending between a first end 118 and a second end 120 of the support 104. For example... Figure 3AAs further illustrated, in some non-limiting embodiments, the first plate-like element 112 and the second plate-like element 114 may extend from the elongated body 116 in a manner parallel to each other and substantially perpendicular to the elongated body 116, such that the outer surfaces 112a of the first plate-like element 112 and the outer surfaces 114a of the second plate-like element 114 may face opposite directions. Similarly, the inner surfaces 112b of the first plate-like element 112 and the inner surfaces 114b of the second plate-like element 114 may face each other.

[0042] Continue to refer to Figures 3A to 3C In some non-limiting embodiments, the elongated body 116 may include a first bend 138 located at a first end 118 of the support 104 and a second bend 140 located at a second end 120 of the support 104. In some non-limiting embodiments, a first plate-like element 112 may extend from the first bend 138, and a second plate-like element 114 may extend from the second bend 140. In some non-limiting embodiments, the bend 138 may define the connection angle between the first plate-like element 112 and the elongated body 116, and the bend 140 may define the connection angle between the second plate-like element 114 and the elongated body 116. For example, as... Figure 3A As shown, the first bend 138 and the second bend 140 can be bends of 90 degrees, such that the first plate-shaped element 112 and the second plate-shaped element 114 are parallel to each other and substantially perpendicular to the elongated body 116.

[0043] However, it is also conceivable that the first bend 138 and the second bend 140 can be configured to hold the first plate-like element 112 and the second plate-like element 114 at any advantageous angle relative to the elongated body 116 and / or relative to each other (e.g., rigidly). For example, in the case where the elongated body 116 is curved or includes angled portions, it may be advantageous for the first plate-like element 112 and the second plate-like element 114 to be held at a non-90-degree angle relative to the elongated body 116, such that the first plate-like element 112 and the second plate-like element 114 remain substantially parallel to each other. In another exemplary embodiment, in the case where the elongated body 116 is curved or includes angled portions, it may be advantageous for the first plate-like element 112 and the second plate-like element 114 to be held at an angle relative to the elongated body 116, such that the first plate-like element 112 and the second plate-like element 114 are each held at approximately 90 degrees relative to the elongated body rather than parallel to each other. Such a configuration may be necessary and / or advantageous in cases where the hollow element 102 is not a straight hollow segment, for example, thereby allowing the shape of the support 104 to correspond to the shape of the hollow element 102.

[0044] In some non-limiting embodiments, the support 104 may be a single piece of metal, such as a sheet of metal. For example, the support 104 may be stamped from a sheet of metal such as aluminum, steel, etc. The first plate-shaped element 112 and the second plate-shaped element 114 may then be bent relative to the elongated body 116 to form a first bend 138 and a second bend 140. In some non-limiting embodiments, the thickness of the sheet metal is sufficient to give the support 104—including the connection between each of the first plate-shaped element 112 and the second plate-shaped element 114 and the elongated body 116—rigidity. For example, the first bend 138 and the second bend 140 may be thick enough and / or strong enough to prevent pivoting or rotation of the first plate-shaped element 112 and the second plate-shaped element 114 relative to the elongated body 116. In other non-limiting embodiments, the first plate-shaped element 112 and / or the second plate-shaped element 114 may be formed separately from the elongated body 116 and then attached to, for example, by welding, the elongated body 116. Such a connection (e.g., a welded joint) can have sufficient strength to prevent the first plate element 112 and the second plate element 114 from pivoting or rotating relative to the elongated body 116.

[0045] In another non-limiting embodiment, the elongated body 116 can be formed as a separate component, including a first component and a second component. The first component includes a first plate-like element 112 and a portion of the elongated body 116, and the second component includes a second plate-like element 114 and the remaining portion of the elongated body 116. The first and second components can be connected along the length of the elongated body 116 by an interlocking connection, such as a press-fit connection mechanism, a threaded connection mechanism, a tongue-and-groove connection mechanism, or other connection mechanism. In this embodiment, the bracket 104 can be assembled into the hollow element 102 by inserting a first portion of the bracket 104 (e.g., the first portion including the first plate-like element 112 and a portion of the elongated body 116) through a first end 108 of the hollow element 102, inserting a second portion of the bracket 104 (e.g., the second portion including the second plate-like element 114 and a portion of the elongated body 116) through a second end 110 of the hollow element 102, and connecting these portions of the elongated body 116 together to form the bracket 104.

[0046] The first aperture 122 and the second aperture 124 may be stamped from the first plate-shaped element 112 and the second plate-shaped element 114, or the first aperture 122 and the second aperture 124 may be drilled into the first plate-shaped element 112 and the second plate-shaped element 114. In embodiments where the first aperture 122 and the second aperture 124 are configured for threaded engagement, the first aperture 122 and the second aperture 124 may be tapped to form threads through which they engage with threaded fasteners. As described above, in some non-limiting embodiments, the first plate-shaped element 112 and the second plate-shaped element 114 may not have pre-formed apertures, and may instead include thinner or weakened portions (e.g., portions thinned or weakened by half-shearing) through which fasteners can easily penetrate.

[0047] In some non-limiting embodiments, the support 104 has a length that substantially corresponds to the length of the hollow element 102. For example, in some non-limiting embodiments, when the support 104 is inserted into the hollow element 102, the first plate-like element 112 may be substantially aligned with the first end 108 of the hollow element 102, and the second plate-like element 114 may be substantially aligned with the second end 110 of the hollow element 102. In some non-limiting embodiments, when the support 104 is inserted into the hollow element 102, the outer surface 112a of the first plate-like element 112 may be substantially aligned with (e.g., flush or substantially flush with) the first end 108 of the hollow element 102, and the outer surface 114a of the second plate-like element 114 may be substantially aligned with (e.g., flush or substantially flush with) the second end 110 of the hollow element 102. This configuration allows the frame attachment assembly 100 to be positioned close to and / or in contact with adjacent frame members, such that the first end 108 and the second end 110 of the hollow element 102 are simultaneously flush with the corresponding frame members, such as... Figure 5A and Figure 6 As shown in the figure.

[0048] Now for reference Figures 4A to 4C , Figures 4A to 4CThese are perspective and side views of a non-limiting embodiment of the hollow element 102 of the frame attachment assembly 100 according to the present disclosure. In some non-limiting embodiments, the hollow element 102 may include at least one surface portion configured to engage with a complementary surface portion of the first plate-like element 112 or the second plate-like element 114 when the support 104 is inserted into the hollow element 102, thereby preventing the support 104 from rotating within the hollow element 102. In some non-limiting embodiments, the shape of the internal hollow portion 142 of the hollow element 102 may correspond to the shape of the first plate-like element 112 and / or the second plate-like element 114. For example, in some non-limiting embodiments, the first plate-like element 112 and / or the second plate-like element 114 may be square, triangular, hexagonal, octagonal, or any other irregular shape or shape containing angles, and the shape of the internal hollow portion 142 of the hollow element 102 may correspond to the shape of the first plate-like element 112 and / or the second plate-like element 114. In such an embodiment, the shape of the inner hollow portion 142 can engage with the corresponding shape of the first plate-like element 112 and / or the second plate-like element 114 and prevent the support 104 from rotating within the hollow element 102. In some non-limiting embodiments, the outer (e.g., external) contour or shape of the elongated body 106 of the hollow element 102 may correspond to the shape of the inner hollow portion 142, or may be different. For example, the inner hollow portion 142 may be square, while the outer contour of the elongated body 106 may be circular (e.g., cylindrical). For example, when the hollow element 102 is used as a handle or other frame element intended to be gripped by a user, such as... Figure 4A and Figure 6 The cylindrical outer profile shown may be advantageous. However, the outer profile of the hollow element 102 can exhibit other cross-sectional shapes, such as rectangular, square, elliptical, or triangular. Furthermore, as mentioned above, the hollow element 102 can be straight along its axial length, such as... Figure 4A As shown, or, the hollow element 102 may be curved.

[0049] In some non-limiting embodiments, such as Figures 4A to 4C As shown, the hollow element 102 may be cylindrical, such that both the internal hollow portion 142 and the outer contour of the elongated body 106 comprise a circular cross-section. In some non-limiting embodiments, such as Figures 3A to 3CAs shown, at least one of the first plate-like element 112 and the second plate-like element 114 may include at least one circular portion 130 configured to engage with the radially inner surface of the cylindrical hollow element 102, for example, with the inner hollow portion 142. In some non-limiting embodiments, when the support 104 is inserted into the hollow element 102, at least one circular portion 130 engages with the inner hollow portion 142 or the radially inner surface of the cylindrical hollow element 102 (e.g., as shown). Figures 2A to 2C (As shown in the diagram) to guide the support 104 within the hollow element 102 and prevent radial movement of the support 104 relative to the hollow element 102. The hollow element 102 may include one or more protrusions 136 extending from a first end 108 and / or a second end 110 of the hollow element 102. In some non-limiting embodiments, the protrusions 136 may extend axially from the first end 108 and / or the second end 110 such that the protrusions 136 extend from a lip or edge at the end of the elongated body 106 of the hollow element 102. As will be further described below, the protrusions 136 may engage with complementary openings or recesses on the frame to facilitate securing the hollow element 102 to the frame.

[0050] refer to Figures 2A to 4C In some non-limiting embodiments, the first plate-like element 112 may include a tongue-like portion 132 extending radially from the outer peripheral edge of the first plate-like element 112, and the hollow element 102 may include a recess 134, such as a recess located at the first end 108, the recess being configured to receive or engage with the tongue-like portion 132. For example, the tongue-like portion 132 may sit within the recess 134, thereby allowing the first plate-like element 112 to rest flush with or substantially flush with the first end 108 of the hollow element 102, such as... Figure 2B As shown. In some non-limiting embodiments, the second plate-like element 114 may also include, or alternatively include, a tongue-like portion (not shown, but similar to tongue-like portion 132) extending radially from the outer peripheral edge of the second plate-like element 114, and the hollow element 102 may include a second recess (not shown, but similar to recess 134), for example, a second recess at the second end 110, and the second recess may be configured to receive the tongue-like portion of the second plate-like element 114. Embodiments in which both the first plate-like element 112 and the second plate-like element 114 include tongue-like portions can be used in conjunction with the embodiments discussed above, in which the elongated body 116 of the support 104 includes a plurality of components connected together within the hollow element 102.

[0051] In some non-limiting embodiments, the first plate-like element 112 may include a notch located on its outer peripheral edge, and the hollow element 102 may include a tongue-like portion, such as a tongue-like portion located at the first end 108, and the tongue-like portion of the first hollow element 102 may be configured to be received in the notch of the first plate-like element 112. In some non-limiting embodiments, the second plate-like element 114 may also include, or alternatively include, a notch located on its outer peripheral edge, and the hollow element 102 may include a second tongue-like portion, such as a second tongue-like portion located at the second end 110, and the second tongue-like portion may be configured to be received in the notch of the second plate-like element 114.

[0052] When the support 104 is inserted into the hollow element 102, such as when the frame attachment assembly 100 is used to secure a frame member at the first end 108 and / or the second end 110, the engagement between one or more tongues and one or more notches can prevent the support 104 from rotating within the hollow element 102. For example, when the tongue 132 engages with the notch 134 (e.g., when the tongue 132 is seated within the notch 134), this engagement can prevent the support 104 from rotating within the hollow element 102 because the notch 134 restricts the rotational movement of the tongue 132.

[0053] Now for reference Figures 5A to 5B , Figures 5A to 5B These are perspective cross-sectional views and detailed views of a non-limiting embodiment of the framework 500 of this disclosure. (As shown...) Figure 5AAs shown, frame 500 may include a frame attachment assembly that is the same as or similar to frame attachment assembly 100, or frame 500 may include components of a frame attachment assembly, wherein similar portions are referred to by similar reference numerals. Frame 500 may include a first frame member 556a and a second frame member 556b. Frame 500 may also include a hollow element (e.g., hollow element 102) located between the first frame member 556a and the second frame member 556b. In some non-limiting embodiments, the first frame member 556a and the second frame member 556b may be positioned at opposite ends of the hollow element. Frame 500 may also include a support (e.g., support 104) received within the hollow element. The support may include an elongated body (e.g., elongated body 116) extending between a first end (e.g., first end 108) and a second end (e.g., second end 110). The support may also include a first plate-like element (e.g., plate-like element 112) positioned at the first end, the first plate-like element including a first aperture (e.g., first aperture 122). The first aperture may be configured to receive a first fastener 558a. The frame 500 may also include a second plate-like element (e.g., second plate-like element 114) positioned at a second end, and the second plate-like element may include a second aperture (e.g., second aperture 124) that may be configured to receive a second fastener 558b.

[0054] The first plate-shaped element can be secured to the first frame member 556a by a first fastener 558a, which extends through a portion of the first frame member 556a and engages with a first orifice of the first plate-shaped element. In some non-limiting embodiments, the second plate-shaped element can be secured to the second frame member 556b by a second fastener 558b, which extends through a portion of the second frame member 556b and engages with a second orifice of the second plate-shaped element.

[0055] Now for reference Figure 6 , Figure 6 This is a perspective view of a non-limiting embodiment of the framework 600 of this disclosure. (See diagram below.) Figure 6 As shown, frame 600 may be the same as or similar to frame 500, and frame 600 may include a frame attachment assembly that may be the same as or similar to frame attachment assembly 100 or its components, wherein similar portions are referred to by similar reference numerals. In some non-limiting embodiments, such as Figure 6As shown, the hollow element of frame 600 (e.g., hollow element 102) may include at least one engaging surface portion configured to engage with a complementary surface portion of a first frame member (e.g., first frame member 556a) or a complementary surface portion of a second frame member (e.g., second frame member 556b) to prevent the hollow element from rotating relative to the first frame member and / or the second frame member. For example, as Figures 2A to 2C and Figures 4A to 4C As shown and discussed above, the hollow element 102 may include one or more protrusions 136 extending from a first end 108 and / or a second end 110 of the hollow element 102, such as protrusions 136 extending axially from a lip or edge at the end of the elongated body 106 of the hollow element 102. In some exemplary embodiments, engagement surfaces, such as protrusions 136, may be configured to engage recesses or openings (e.g., recess 660) of the first frame member and / or the second frame member. Engagement between the engagement surfaces of the hollow element and complementary surfaces of the first frame member or the second frame member can prevent rotation of the hollow element relative to the first frame member and / or the second frame member. Figure 6 The hollow element 102 can be used as a handle that can be gripped by the user.

[0056] In some non-limiting embodiments, such as Figure 6 As shown, the first frame member 556a and the second frame member 556b may be generally parallel to each other, and the hollow element may be generally perpendicular to the first frame member 556a and the second frame member 556b. In some non-limiting embodiments, depending on the intended use of the frame, the first frame member 556a and the second frame member 556b may be held at an angle relative to each other and / or relative to the hollow element.

[0057] According to another aspect of this disclosure, a method of assembling the frame may include inserting a support into a hollow element. For example, the support may be the same as or similar to support 104. Similarly, for example, the hollow element may be the same as or similar to hollow element 102. In an exemplary embodiment, the support may include: an elongated body (e.g., elongated body 116) extending between a first end (e.g., first end 118) and a second end (e.g., second end 120) of the support; a first plate-like element (e.g., first plate-like element 112) positioned at the first end of the support, the first plate-like element including a first aperture (e.g., first aperture 122) configured to receive a first fastener (e.g., first fastener 558a); and a second plate-like element (e.g., second plate-like element 114) positioned at the second end of the support, the second plate-like element including a second aperture (e.g., second aperture 124) configured to receive a second fastener (e.g., second fastener 558b). The method may further include: positioning the hollow element with the inserted bracket between a first frame member (e.g., first frame member 556a) and a second frame member (e.g., second frame member 556b); fixing the bracket to the first frame member and the second frame member by positioning a first fastener through a portion of the first frame member and engaging the first fastener with a first orifice, and positioning a second fastener through a portion of the second frame member and engaging the second fastener with a second orifice.

[0058] In some non-limiting embodiments, the first frame member and the second frame member may be substantially parallel to each other. In some non-limiting embodiments, when positioning the hollow element with the inserted support between the first frame member and the second frame member, the method may further include positioning the hollow element substantially perpendicular to the first and second frame members. In some non-limiting embodiments, when positioning the support in the hollow element, the method may further include aligning at least one surface portion of the hollow element with a complementary surface portion of the first plate-like element or the second plate-like element to prevent rotation of the support within the hollow element, the at least one surface portion being configured to engage with the complementary surface portion of the first frame member or the second frame member. For example, the method may include aligning and engaging one or more protrusions (e.g., protrusion 136) of the hollow element with corresponding recesses (e.g., recess 660) of the first and second frame members.

[0059] Although the apparatus, components, and methods of this disclosure are shown in the accompanying drawings and described in detail above with reference to attaching hollow frame components to other frame components, it is to be understood that the implementation of the apparatus, components, and methods is also applicable to other applications, such as to attaching various components to form various structures other than those described herein.

[0060] While several examples of systems and methods for attaching hollow frame components to other frame components have been shown in the accompanying drawings and described in detail above, other aspects will be apparent and readily achievable by those skilled in the art without departing from the scope and spirit of this disclosure. Therefore, the foregoing description is intended to be illustrative rather than restrictive. The disclosure provided above is defined by the appended claims, and all modifications to exemplary, non-limiting embodiments falling within the meaning and scope of the equivalence of the claims are to be included within the scope of this disclosure.
