Mode for Carrying Out the Invention
[0014] Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings. (First Embodiment) As shown in FIGS. 1 and 2, in the folding table 100 according to the first embodiment of the present invention, four support frames 2 form a rectangular framework, and the tips of the respective support frames 2 are inserted into the connecting member 1, whereby the plurality of support frames 2 are coupled to the connecting member 1. When the rectangular framework is formed in this way, each connecting member 1 is positioned between the support frames 2. A top plate 3 is coupled to the upper part of the rectangular framework, and four leg frames 4 are coupled to the respective connecting members 1 at the lower part.
[0015] The framework formed by the support frame 2 may be another polygon such as a square or a pentagon in addition to a rectangle. The shape of the top plate 3 coupled to the upper part of the framework may change according to the shape of the polygonal framework. Since the framework formed by the plurality of support frames 2 has rigidity, even if the top plate 3 made of a lightweight material with relatively weak structural rigidity is coupled, the stability of the table can be ensured. Therefore, the folding table 100 of the present invention reduces the weight of the top plate to lighten the table while maintaining the stability during use of the table.
[0016] Since the top plate 3 functions to place and support objects, it generally has a wide plate shape. In this embodiment, the top plate 3 is a rectangular plate, but it is not limited to such a shape, and it may have other shapes according to the polygonal framework as described above. For example, the top plate 3 may have a shape of another polygon different from a square, or may have a shape such as a circle or an ellipse. Also, in this embodiment, the support frame 2 and the leg frame 4 are rod-shaped with a circular cross section, but they are not necessarily limited to such a shape. For example, the support frame 2 and the leg frame 4 may have a polygonal cross section such as a rectangle or a square.
[0017] When the leg frame 4 is coupled to the connecting member 1, an anti-slip member 48 formed of a material such as rubber may be coupled to the lower end of the leg frame 4 that contacts the ground. By coupling the anti-slip member 48, it is possible to prevent the formation of pressure marks on the ground, and since the friction force with the ground prevents the table from slipping, the stability of the table can be enhanced.
[0018] As shown in FIGS. 3 and 4, the connecting member 1 has a square plate-shaped upper part on which the top plate 3 can be placed, two side grooves 11 into which the support frame 2 is inserted, a lower groove 12 into which the leg frame 4 is inserted, and four connecting holes 13 through which the fixing piece 101 passes when coupled to the top plate 3. The upper part of the connecting member 1 on which the top plate 3 is placed preferably has a flat end face in order to increase the contact area with the top plate 3 and ensure a reliable connection with the top plate 3. In addition to being square, the upper part may have a plate shape such as circular.
[0019] The connecting member 1 and the top plate 3 are joined in such a way that the fixing piece 101 passes through the connecting hole 13 and is inserted into the top plate 3. In addition, the connecting member 1 and the top plate 3 can be joined by other methods. The number of fixing pieces 101 can be changed according to the design, joining method, etc. Since the support frame 2 forms a square framework, the side grooves 11 are parallel to the ground and two are formed in directions perpendicular to each other. The support frame 2 is joined in such a way that both ends of the support frame 2 are respectively inserted into the side grooves 11 of the connecting member 1.
[0020] The lower groove 12 may be formed perpendicular to the top plate 3, or may be formed to extend inclined with respect to the top plate 3 so that when a plurality of leg frames 4 are inserted into the connecting member 1, the distance between the plurality of leg frames 4 gradually increases toward the floor surface. The degree of inclination with respect to the top plate 3 may vary depending on the design of those skilled in the art. When the lower groove 12 is formed to extend inclined with respect to the top plate 3 in this way, the degree of rattling caused by the gap between the lower groove 12 and the leg frame 4 when the leg frame 4 is inserted into the connecting member 1 can be reduced.
[0021] The leg frame 4 is joined to the lower part of the connecting member 1. The upper end of the leg frame 4 is detachably inserted into the lower groove 12 formed in the lower part of the connecting member 1. The plurality of leg frames 4 removed from the connecting member 1 can be fitted into and stored in the storage member 5 formed in the lower part of the table. Therefore, since there is no need to store the leg frames 4 separately, management is easy.
[0022] FIG. 5a is a diagram showing a state in which a plurality of leg frames 4 are all coupled to the coupling member 1 for use of the foldable table 100. As shown in FIG. 5a, the storage member 5 is attached to support frames 2 that form opposite left and right sides among a plurality of support frames 2 forming a polygonal framework, respectively.
[0023] FIG. 5b is a diagram showing a stored state of the foldable table 100. As shown in FIG. 5b, when the plurality of leg frames 4 are removed from the coupling member 1, the leg frames 4 are fitted into the storage member 5 and stored. This facilitates carrying and storing the table. Referring to FIG. 6, the storage member 5 includes a pair of coupling wings 52 in the shape of an isosceles trapezoid disposed at both ends of the support frame 2 when coupled to the support frame 2, and a plurality of gripping blocks 54 formed at a certain interval below the pair of coupling wings 52 so that the leg frames 4 removed from the coupling member 1 can be fitted therein. The cross-section of the coupling wing 52 is not limited to the shape of an isosceles trapezoid and may be in other forms.
[0024] In this embodiment, the coupling method between the storage member 5 and the support frame 2 is a method of coupling by fastening a fastening bolt 102 and a fastening nut 103. The pair of coupling wings 52 each include a fastening hole 53 through which the fastening bolt 102 passes when the storage member 5 is coupled to the support frame 2. A hole through which the fastening bolt 102 can pass may also be formed in the support frame 2 in the same manner as the fastening hole 53. The storage member 5 and the support frame 2 are coupled by the fastening bolt 102 passing through the fastening hole 53 and the support frame 2 and then being fastened to the fastening nut 103.
[0025] The storage member 5 may be made of a flexible material. In this case, when the leg frame 4 removed from the coupling member 1 is fitted into the storage member 5, the gripping block 54 can be elastically deformed to fix the leg frame 4. Only the gripping block 54 of the storage member 5 into which the leg frame 4 is fitted may be made of a flexible material.
[0026] FIGS. 7a and 7b are diagrams showing the structure in which the leg frame 4 is coupled to the coupling member 1. Referring to Fig. 7a, a sleeve 15 is inserted inside the lower groove 12 of the connecting member 1. When the leg frame 4 is inserted into the lower groove 12, the sleeve 15 is positioned between the inner surface of the lower groove 12 and the outer surface of one end of the leg frame 4. As a coupling method for arranging the sleeve 15 inside the lower groove 12, there are methods such as utilizing a bond or pushing it in.
[0027] The structure in which the sleeve 15 is inserted into the lower groove 12 of the connecting member 1 has the effect of increasing the stability of the table. When the leg frame 4 is inserted into the connecting member 1, a gap may occur between the lower groove 12 of the connecting member 1 and one end of the inserted leg frame 4. Such a gap may cause the leg frame 4 to rattle when the table is placed on the ground for use, reducing the stability of the table. The sleeve 15 serves to minimize the gap that may exist between the lower groove 12 and one end of the leg frame 4 in order to reduce such rattling and increase the stability of the table.
[0028] The leg frame 4 may include a hole 41 formed on the outer peripheral surface of one end and a pressing protrusion 42 disposed inside one end and protruding radially from the outer peripheral surface through the hole 41. When the leg frame 4 is easily removed from the lower groove 12 of the connecting member 1 when the table is used by inserting the leg frame 4 into the connecting member 1, there is a problem that the stability of the table is reduced. At this time, when the pressing protrusion 42 is pressed inside the lower groove 12, it has the effect of preventing the leg frame 4 from accidentally coming off, reducing the rattling of the leg frame 4, and enhancing the stability of the table.
[0029] In addition, the leg frame 4 is provided with an elastic member 43 inside one end thereof, which applies an elastic force in the radial direction to the pressing protrusion 42. Referring to FIG. 7b, the elastic member 43 provides an elastic force such that when the leg frame 4 is inserted into the connecting member 1, the pressing protrusion 42 is pressed against the inside of the lower groove 12 of the connecting member 1. Thereby, rattling of the leg frame 4 can be reduced, and the leg frame 4 can be prevented from accidentally coming off from the connecting member 1, enhancing the stability of the table. The elastic member 43 may preferably be a spring.
[0030] (Modification of the leg frame) Referring to FIG. 8a, the leg frame 4 may be provided with an elastic clip 45 instead of the pressing protrusion 42 and the elastic member 43 of the first embodiment described above. The clip 45 may include a support portion 44 that contacts and is supported by the inner peripheral surface of the leg frame 4, a protruding portion 46 including a protrusion that is pressed against the inner surface of the connecting member 1 when the leg frame 4 is inserted into the connecting member 1, and a curved portion 47 that connects the support portion 44 and the protruding portion 46 and applies an elastic force in a direction away from each other.
[0031] As shown in FIG. 8b, the protrusion of the protruding portion 46 is pressed against the inner surface of the lower groove 12 of the connecting member 1 through a hole 41 formed in the outer peripheral surface of one end of the leg frame 4. Such a clip 45 may preferably have a U-shape or a V-shape so that the support portion 44 and the protruding portion 46 can easily apply an elastic force in a direction away from each other. Similar to the pressing protrusion 42 of the first embodiment described above, the clip 45 prevents the leg frame 4 from accidentally coming off and reduces rattling of the leg frame 4 by pressing the protrusion of the protruding portion 46 against the inside of the lower groove 12, thereby enhancing the stability of the table.
[0032] (Second embodiment) Hereinafter, a folding table according to a second embodiment of the present invention will be described with reference to FIGS. 9 and 10. Note that the same or corresponding reference numerals are assigned to the same or corresponding configurations as those of the first embodiment described above, and descriptions overlapping with those of the first embodiment are omitted.
[0033] Referring to FIG. 9a, since the connecting member 1 of the folding table 100 according to the second embodiment of the present invention extends in a form that forms two parallel sides of a rectangular framework, when it is combined with the two support frames 2 to form a rectangular framework, it forms two opposite sides. The two support frames 2 are arranged in parallel, and the tips of the respective support frames 2 are inserted into the side grooves 11 of the respective connecting members 1 arranged in parallel to form a rectangular framework. The connecting member 1 further includes a storage portion 14 into which a plurality of leg frames 4 removed from the lower surface are detachably fitted.
[0034] As shown in FIG. 9b, when the plurality of leg frames 4 are removed from the connecting member 1, the leg frames 4 are fitted into the storage portion 14 and stored. The storage portion 14 is made of a flexible material. Therefore, when the leg frame 4 removed from the connecting member 1 is fitted into the storage portion 14, it can be elastically deformed to fix the leg frame 4.
[0035] The folding table 100 according to the above-described embodiment can ensure structural rigidity by combining the support frames 2 that form a polygonal framework. Therefore, even when a tabletop 3 made of a lightweight material with relatively weak structural rigidity is combined to enhance the ease of carrying and storage, the table can have stability. On the other hand, as shown in FIG. 11, the tabletop 3 may be made of a lightweight and relatively weak-rigidity honeycomb structure. The tabletop 3 may be made of a honeycomb panel, a wooden plywood, a damper panel, or the like.
[0036] The above description merely exemplarily explains the technical idea of the present invention, and various modifications and variations are possible for those with ordinary knowledge in the technical field to which the present invention pertains without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but for the purpose of explanation, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be construed as being included in the scope of rights of the present invention.
