Description

Assembly frame {Assembly frame}

The present invention relates to an assembly frame, and more particularly, to an assembly frame having a structure that can be simply assembled while maintaining a sturdy and distortion-free assembled state.

Recently, various types of modular furniture have been developed for furniture such as beds, desks, storage units, and chairs. Modular furniture has the advantage of being easy to deliver and takes up little space, making it easy to store. Furthermore, modular modular furniture with various combinations has the characteristic of being able to be transformed into the desired form by the user. The basis of such modular furniture is an external frame in which each frame is connected to each other so that they are adjacent to each other, and in some cases, a separate frame connector (or bracket) is used to connect each frame to each other. Each frame is usually made of a metal material in the shape of a tube (round or square pipe) with an empty interior, and the frames are connected to each other through frame connectors while each frame is arranged vertically or horizontally so that it is adjacent to each other, thereby forming the external frame of the structure.

Meanwhile, in the past, the most commonly used method was to connect frames by fastening an 'L'-shaped bracket to one side of each frame with a bolt while the sides of the frames are placed at right angles to each other in order to connect the frames. However, the conventional frame connector (or bracket) is connected only to one side of the frame using a bolt while each frame is inserted into the frame connector and tightly attached, so the fastening force is weak. If an external force such as an impact is transmitted from the outside, the frames may warp and the shape of the frame may be deformed or the frame may be separated from the frame connector and damaged. Such conventionally assembled frames have problems such as difficulty in maintaining the initial state of the frames being installed, low durability of structures such as furniture, and high frictional force makes it difficult for the frame to be smoothly connected to the frame connector because the inner side of the frame connector and the outer side of the frame are inserted and connected in a completely tight state. In addition, when welding is performed to connect frames to frames, it is difficult to connect the frames at the exact desired position and angle due to thermal deformation, etc., and it is difficult to repair because they cannot be separated, and there is a problem that the user cannot assemble and use them in the desired form.

The problem to be solved by the present invention is to provide an assembly frame having a structure that can be assembled simply while maintaining a sturdy and distortion-free assembled state.

According to one embodiment of the present invention for achieving the above object, a prefabricated frame comprises: a horizontal frame having a column shape extending in a horizontal direction and having at least one first through hole formed at a position spaced from an end of an outer surface; a vertical frame having a column shape extending in a vertical direction and having at least one second through hole formed at a position spaced from an end of an outer surface; a first connecting frame inserted into one end of the horizontal frame and a second connecting frame inserted into one end of the vertical frame are formed by bending and extending, a first fixing groove having a cross-sectional shape corresponding to the first through hole is formed at a position corresponding to the first through hole of the first connecting frame, and a second fixing groove having a cross-sectional shape corresponding to the second through hole is formed at a position corresponding to the second through hole of the second connecting frame; a first joining surface having a cross-sectional shape corresponding to the cross-sections of the first through hole and the first joining surface; The first fastening means may include a first extension surface formed by bending and extending, and the first coupling surface is fitted into the first fixing groove while penetrating the first through hole to couple and fix the horizontal frame and the corner connecting frame, a second coupling surface having a cross-sectional shape corresponding to the cross-sections of the second through hole and the second fixing groove, and a second coupling means including a second extension surface formed by bending and extending with the second coupling surface, and the second coupling surface is fitted into the second fixing groove while penetrating the second through hole to couple and fix the horizontal frame and the corner connecting frame.

The first fastening means may be formed in a vertical direction and include a first coupling surface that is vertically inserted into the first fixing groove while vertically penetrating the first through hole, and a first extension surface that is formed by being bent and extended from one end of the first coupling surface, and the second fastening means may be formed in a horizontal direction and include a second coupling surface that is horizontally inserted into the second fixing groove while horizontally penetrating the second through hole, and a second extension surface that is formed by being bent and extended from one end of the second coupling surface.

The first extension surface may include a first plate mounting surface that is formed by being extended by being bent at least once from one end that is not connected to the first joining surface so that plate-shaped plates are joined, and the second extension surface may include a second plate mounting surface that is formed by being extended by being bent at least once from one end that is not connected to the second joining surface so that plate-shaped plates are joined.

The above corner connecting frame has a base frame formed at a portion where the first connecting frame and the second connecting frame come into contact, and a portion of the base frame connected to the first connecting frame may have a cross-sectional area larger than the cross-sectional area of the horizontal frame so that a horizontal frame inserted into the first connecting frame does not move inwardly of the base frame, or a portion of the base frame connected to the second connecting frame may have a cross-sectional area larger than the cross-sectional area of the vertical frame so that a vertical frame inserted into the second connecting frame does not move inwardly of the base frame.

A screw may be fixed by being engaged in a first screw through-hole formed in the horizontal frame and a first screw mounting groove formed at a position corresponding to the first screw through-hole in the first connecting frame, or a screw may be fixed by being engaged in a second screw mounting groove formed at a position corresponding to the second screw through-hole in the horizontal frame and the second connecting frame.

According to one embodiment of the technical idea of the present invention, in the case where a corner portion is to be created by connecting the ends of a horizontal frame and a vertical frame, the corner connection frame can be simply assembled by using a fastening means to a horizontal frame or a vertical frame without forcibly fitting the corner connection frame into the horizontal frame or the vertical frame. In addition, compared to the case where screws are used for joining, the assembly can be supported with a stronger force, so that twisting and separation in the assembled state can be prevented, and a firmly fixed state can be maintained.

In addition, when using an assembly frame according to one embodiment of the technical idea of the present invention, there is no need for welding when connecting the vertical frame and the horizontal frame, so there are advantages of no defects due to thermal deformation, easy maintenance, easy assembly and disassembly, and an attractive appearance.

In addition, when using an assembly frame according to one embodiment of the technical idea of the present invention, there is an advantage in that a shelf, a desk top, a footrest, a screen, etc. can be easily installed on the assembly frame by assembling it by connecting a flat plate to a fastening means.

Hereinafter, the present invention will be described in detail by describing a preferred embodiment of the present invention with reference to the attached drawings. The same reference numerals presented in each drawing represent the same components.

FIG. 1 is a drawing showing a coupled state of an assembly frame (100) according to one embodiment of the technical idea of the present invention, and FIG. 2 is an exploded perspective view of the assembly frame (100) of FIG. 1. FIG. 3 is a drawing showing a case where a fastening means (310) is coupled according to another embodiment of the assembly frame (100) of FIG. 1, and FIG. 4 is a drawing showing a case where a plate (410) is coupled to the fastening means (130) of FIG. 1. FIG. 5 is a drawing showing a case where a fastening means (510) is coupled according to another embodiment of the assembly frame (100) of FIG. 1, and FIG. 6 is a drawing showing a case where a plate (410) is coupled to the fastening means (510) of FIG. 5.

Referring to FIGS. 1 to 6, an assembly frame (100) according to one embodiment of the technical idea of the present invention may include a horizontal frame (110), a vertical frame (120), a connecting frame (150), a first fastening means (130), and a second fastening means (140).

The horizontal frame (110) has a columnar shape extending horizontally, and at least one first through hole (111) can be formed at a position spaced apart from an end of the outer surface. That is, the horizontal frame (110) is a portion that is horizontally fastened in a completed assembled frame. The horizontal frame (110) has a columnar shape, and its cross-section may have a polygonal shape or may be circular. The first through hole (111) can be formed to penetrate the outer surface at a position spaced apart from an end of the horizontal frame (110), and one or more first through holes (111) can be formed. The first through holes (111) can be formed on only one side of the outer surface of the horizontal frame (110), or can be formed as a pair on facing surfaces.

The vertical frame (120) has a columnar shape extending vertically, and at least one second through hole (121) may be formed at a position spaced apart from an end of the outer surface. That is, the vertical frame (120) is a part that is vertically fastened in a completed assembled frame. The vertical frame (120) has a columnar shape, and its cross-section may have a polygonal shape or may be circular. The second through hole (121) may be formed to penetrate the outer surface at a position spaced apart from an end of the vertical frame (120), and one or more second through holes (121) may be formed. The second through holes (121) may be formed on only one side of the outer surface of the vertical frame (120), or may be formed as a pair on facing sides.

The horizontal frame (110) and the vertical frame (120) may have the same shape with only the direction in which they are fastened being different. That is, if a frame having a columnar shape and having at least one through hole formed at a position spaced from the end of the outer surface is fastened horizontally, it may become a horizontal frame (110), and if it is fastened vertically, it may become a vertical frame (120).

The corner connecting frame (150) is a frame that connects the horizontal frame (110) and the vertical frame (120), and by connecting the end of the horizontal frame (110) and the end of the vertical frame (120) by the corner connecting frame (150), a corner portion of the assembled frame (100) can be formed. To this end, the corner connecting frame (150) can be equipped with a first connecting frame (151), a second connecting frame (152), and a base frame (153). The first connecting frame (151) is a portion inserted into one end of the horizontal frame (110), and the second connecting frame (152) is a portion inserted into one end of the vertical frame (120). In addition, the first connecting frame (151) and the second connecting frame (152) are formed by bending and extending. For example, a base frame (153) may be connected between the first connecting frame (151) and the second connecting frame (152). The first connecting frame (151) and the second connecting frame (152) may be directly connected in a direction perpendicular to each other or may be connected through the base frame (153). However, in the present invention, the first connecting frame (151) and the second connecting frame (152) do not necessarily have to be connected in a direction perpendicular to each other, and may have different angles in order to prevent the horizontal frame (110) and the vertical frame (120) from being connected in a direction perpendicular to each other. For example, the angle between the first connecting frame (151) and the second connecting frame (152) may be formed to have various angles such as 45 degrees, 90 degrees, and 120 degrees.

The first connecting frame (151) may have a first fixing groove (210) formed at a position corresponding to the first through hole (111) and having a cross-sectional shape corresponding to the first through hole (111). In addition, the first fastening means (130) may be inserted into the first fixing groove (210) while penetrating the first through hole (111) to couple and fix the horizontal frame (110) and the corner connecting frame (150). The first fastening means (130) may have a first coupling surface (131) and a first extension surface (132) extended and formed. The first coupling surface (131) is a portion inserted into the first fixing groove (210) while penetrating the first through hole (111). That is, the first coupling surface (131) of the first fastening means (130) is formed in a vertical direction so that it can be vertically fitted into the first fixing groove (210) while vertically penetrating the first through hole (111). The first coupling surface (131) may have a cross-sectional shape corresponding to the cross-sections of the first through hole (111) and the first fixing groove (210) so that it can be raised into the first through hole (111) and the first fixing groove (210). For example, when the first coupling surface (131) is circular, the first through hole (111) is a through hole with a circular cross-section, and the portion of the first fixing groove (210) that the first coupling surface (131) comes into contact with may have a circular or curved groove shape so that the circular first coupling surface (131) can be fixed. As another example, when the first coupling surface (131) is square, the first through hole (111) is a through hole with a square cross-section, and the portion of the first mounting groove (210) that the first coupling surface (131) comes into contact with may have a shape of a square or angled groove so that the square first coupling surface (131) can be mounted. FIGS. 1 and 2 illustrate a case where the cross-sections of the first coupling surface (131) and the first through hole (111) are rectangular, and the first mounting groove (210) has a shape of an angled groove in which the first coupling surface (131) can be mounted. However, the present invention is not limited to this case, and the first coupling surface (131) may have various other shapes as long as it can pass through the first through hole (111) and be mounted in the first mounting groove (210).

The second connecting frame (152) may have a second fixing groove (220) formed at a position corresponding to the second through hole (121) and having a cross-sectional shape corresponding to the second through hole (121). In addition, the second fastening means (140) may be inserted into the second fixing groove (220) while penetrating the second through hole (121) to couple and fix the vertical frame (120) and the corner connecting frame (150). The second fastening means (140) may have a second coupling surface (141) and a second extension surface (142) formed to extend. The second coupling surface (141) is a portion inserted into the second fixing groove (220) while penetrating the second through hole (121). That is, the second coupling surface (141) of the second fastening means (140) is formed horizontally and can be horizontally fitted into the second fixing groove (220) while horizontally penetrating the second through hole (121). The second coupling surface (141) can have a cross-sectional shape corresponding to the cross-sections of the second through hole (121) and the second fixing groove (220) so that it can be raised into the second through hole (121) and the second fixing groove (220). For example, when the second coupling surface (141) is circular, the second through hole (121) is a through hole with a circular cross-section, and the portion of the second fixing groove (220) that the second coupling surface (141) comes into contact with can have a circular or curved groove shape so that the circular second coupling surface (141) can be fixed. As another example, when the second coupling surface (141) is square, the second through hole (121) is a through hole with a square cross-section, and the portion of the second mounting groove (220) that the second coupling surface (141) comes into contact with may have a square or angled groove shape so that the square second coupling surface (141) can be mounted. FIGS. 1 and 2 illustrate a case where the cross-sections of the second coupling surface (141) and the second through hole (121) are rectangular, and the second mounting groove (220) has an angled groove shape so that the second coupling surface (141) can be mounted. However, the present invention is not limited to this case, and the second coupling surface (141) may have various other shapes as long as it can pass through the second through hole (121) and be mounted in the second mounting groove (220).

When the corner connecting frame (150) includes a base frame (153) connecting the first connecting frame (151) and the second connecting frame (153), the cross-sectional area of the base frame (153) may be larger than the cross-sectional area of the horizontal frame (110) or the vertical frame (120). For example, the first connecting frame (151) is inserted into the horizontal frame (110), and in this case, to prevent the base frame (153) from being inserted into the horizontal frame (110), the base frame (153) may have a cross-sectional area larger than the cross-sectional area of the horizontal frame (110). As another example, the second connecting frame (152) is inserted into the vertical frame (120), and in this case, to prevent the base frame (153) from being inserted into the vertical frame (120), the base frame (153) may have a cross-sectional area larger than the cross-sectional area of the vertical frame (120).

And, in order to assemble the horizontal frame (110) and the first connecting frame (151) more firmly after connecting them by the first fastening means (130), a first screw through-hole (112) can be formed in the horizontal frame (110) and a first screw mounting groove (211) can be formed at a position corresponding to the first screw through-hole (112) in the first connecting frame (151). In this case, the user can more firmly connect the horizontal frame (110) and the corner connecting frame (150) by attaching a screw to the first screw through-hole (112) and the first screw mounting groove (211) as needed.

In addition, in order to assemble the vertical frame (120) and the second connecting frame (152) more firmly after connecting them by the second fastening means (140), a second screw through-hole (122) may be formed in the vertical frame (120) and a second screw mounting groove (212) may be formed at a position corresponding to the second screw through-hole (122) in the second connecting frame (152). In this case, the user may more firmly connect the vertical frame (120) and the corner connecting frame (150) by attaching a screw to the second screw through-hole (122) and the second screw mounting groove (212) as needed.

Among the first fastening means (130), the first extension surface (132) may be formed by being bent and extended with respect to the first coupling surface (131), and among the second fastening means (140), the second extension surface (142) may be formed by being bent and extended with respect to the second coupling surface (141). The first extension surface (132) or the second extension surface (142) may have various shapes, as illustrated in FIG. 2, FIG. 3, or FIG. 5.

A fastening means (310) having a shape as illustrated in FIG. 3 can replace the first fastening means (130) or the second fastening means (140). The fastening means (310) has a joining surface (311) and an extension surface (312). The joining surface (311) is a portion inserted into the horizontal frame (110) or the vertical frame (120) and the corner connecting frame (150) as described above, and the extension surface (312) can be connected by being bent to the joining surface (311). In addition, the extension surface (312) can be neatly finished with the fastening means (310) by being bent once at one end that is not connected to the joining surface (311). Here, the surface of the extension surface (312) facing the joining surface (311) can be in contact with the vertical frame (110) or the horizontal frame (120) to join and fix the vertical frame (110) or the horizontal frame (120) and the corner joining frame (150).

The first fastening means (130) having the shape as illustrated in FIG. 2 has a first coupling surface (131) and a first extension surface (132). The first coupling surface (131) is a portion inserted into the horizontal frame (110) and the corner connection frame (150) as described above, and the first extension surface (132) can be connected by being folded to the first coupling surface (131). In addition, the first extension surface (132) can have one end that is not connected to the first coupling surface (131) folded twice to form a first plate mounting surface. The first plate mounting surface refers to a surface formed by extending from one end of the first extension surface (132) that is not connected to the first coupling surface (131). In addition, a plate (410) having a plate shape can be coupled to the first plate mounting surface. For example, the first plate mounting surface and the plate (410) may be fastened using a screw or other various fastening means.

The second fastening means (140) having the same shape as that illustrated in FIG. 2 has a second coupling surface (141) and a second extension surface (142). The second coupling surface (141) is a portion inserted into the vertical frame (120) and the corner connecting frame (150) as described above, and the second extension surface (142) can be connected by being folded to the second coupling surface (141). In addition, the second extension surface (142) can form a second plate mounting surface by having one end that is not connected to the second coupling surface (141) folded twice. Since the second plate mounting surface is the same as the first plate mounting surface described above, any subsequent overlapping description will be replaced with a description of the first plate mounting surface.

A fastening means (510) having a shape as illustrated in FIG. 5 may replace the first fastening means (130) or the second fastening means (140). The fastening means (510) has a joining surface (511) and an extension surface (512, 513). The joining surface (511) is a portion inserted into the horizontal frame (110) or the vertical frame (120) and the corner connecting frame (150) as described above, and the extension surface (512, 513) may be connected by being folded to the joining surface (511). In addition, the extension surface (512, 513) may have a shape folded multiple times at one end that is not connected to the joining surface (511), thereby forming a plate mounting surface (513) that performs a function similar to the first plate mounting surface or the second plate mounting surface described above. A plate-shaped plate (610) can be joined to the plate mounting surface (513). For example, the plate mounting surface (513) and the plate (610) can be fastened using a screw or other various fastening means.

By changing the shape of the first extension surface (132) or the second extension surface (142) in this way, the first fastening means (130) or the second fastening means (140) may perform only the function of connecting the horizontal frame (110) and the corner connection frame (150), or may be used as a member for connecting various plate-shaped plate materials such as shelves, top plates, and cover plates to the assembly frame (100) from various directions in addition to the function of connecting the horizontal frame (110) and the corner connection frame (150).

As described above, the best embodiment has been disclosed in the drawings and the specification. Although specific terms have been used herein, they have been used only for the purpose of describing the present invention and have not been used to limit the meaning or the scope of the present invention described in the claims.
