Description

[Technical field]

[0001] The present invention relates to a table leg structure for supporting a tabletop that is rectangular in plan view. [Background technology]

[0002] Conventionally, a table is composed of a table top and legs that support the table top. In order to add value and functionality to the table, various ingenious ideas have been put into the structure of the legs. For example, Patent Document 1 discloses a table whose height can be changed in two stages by rotating legs in which a long leg and a short leg are connected in an L-shape. Patent Document 2 discloses a leg rotation control mechanism that allows a table to be folded by regulating the rotation state of the legs relative to the top (table top). Patent Document 3 discloses a table in which the front-rear and left-right directions of the table top are fixed by legs and table top beam members, respectively, to suppress shaking of the table in the in-plane direction of the table top. Patent Document 4 discloses a leg frame structure for a table for reducing the number of constituent members and increasing rigidity. [Prior art documents] [Patent documents]

[0004] However, in Patent Documents 1 to 4, although the leg structures are different, all four legs are arranged at the four corners of a rectangular top plate in a plan view. This is to stably support the top plate, and is a structure (form) that has been commonly adopted for tables with a rectangular top plate in a plan view. Therefore, in tables with different overall lengths (lengthwise dimensions) of the tabletop, the intervals between the legs arranged in the lengthwise direction of the tabletop are different, and so the dimensions (lengths) of the frame (skirt board, etc.) that connects the legs and supports the table are also different. For this reason, legs with different frame dimensions must be prepared according to the overall length of the tabletop, which creates problems such as a lack of mass production and complicated inventory management.

[0005] An object of the present invention is to provide a table leg structure that can be used commonly for table tops of different overall lengths. [Means for solving the problem]

[0006] As a result of intensive research into solving the above problems, the inventors discovered that by adopting a leg structure in which a first support leg supporting one longitudinal side of the tabletop and a second support leg supporting the other longitudinal side of the tabletop are connected at an adjustable distance, it is possible to stably support the tabletop regardless of the overall length of the tabletop, and that the constituent parts of the leg structure can be standardized for tabletops of different overall lengths, thereby completing the present invention.

[0007] That is, the present invention is as follows. [1] A table leg structure for supporting a rectangular top plate in a plan view, a first support leg supporting one side of the tabletop in the longitudinal direction, and a second support leg connected to the first support leg in a manner that allows an adjustable interval to support the other side of the tabletop in the longitudinal direction; The first support leg includes a contact body that contacts the underside of the top plate and two legs that are vertically attached to the contact body and disposed on both sides of the top plate in the short side direction, The second support leg includes a movable abutment body slidably held by the abutment body and abutting against the underside of the tabletop, and two legs vertically attached to the movable abutment body and disposed on both sides of the tabletop in the short direction. A table leg structure characterized by the above.

[0008] The table leg structure of the present invention is versatile as it can stably support tabletops of different overall lengths by connecting the first support leg and the second support leg in such a way that the distance between them can be adjusted. [Brief description of the drawings]

[0010] The table leg structure of the present invention is a table leg structure for supporting a table top that is rectangular in plan view, and has a first support leg that supports one longitudinal side of the table top, and a second support leg that is connected to the first support leg so that the distance between them can be adjusted and supports the other longitudinal side of the table top, characterized in that the first support leg has an abutment body that abuts against the underside of the table top, and two legs that are hung from the abutment body and positioned on both sides of the short side of the table top, and the second support leg has a movable abutment body that is slidably held by the abutment body and abuts against the underside of the table top, and two legs that are hung from the movable abutment body and positioned on both sides of the short side of the table top.

[0011] By using the table leg structure of the present invention, the distance between the first and second support legs can be easily adjusted, and tabletops of different lengths can be stably supported. In addition, since the tabletop is simply placed on the abutment body of the first support leg and the movable abutment body of the second support leg, no processing or fixing work is required to fix the first and second support legs to the tabletop. The front and back surfaces of the tabletop can be easily interchanged, and by applying this to tabletops decorated with different colors, patterns, or designs, it is possible to enjoy different designs with a single tabletop. Furthermore, a single piece of natural wood can be used as the tabletop, making it possible to construct a table that makes use of its texture and feel.

[0012] The configuration of the leg structure of the table of the present invention will be described in detail below. The leg structure of the table of the present invention is a leg structure of the table for supporting a rectangular tabletop in a plan view, as described above, and has a first support leg for supporting one side of the tabletop in the longitudinal direction, and a second support leg for supporting the other side of the tabletop in the longitudinal direction, which is connected to the first support leg so that the distance between the first support leg can be adjusted. Here, the rectangular tabletop means a tabletop whose main shape is rectangular, and includes, for example, a tabletop having an uneven periphery and each side is not straight, a tabletop having rounded corners, etc.

[0013] The first support leg has a contact body that contacts the underside of the tabletop and two legs that are suspended from the contact body and arranged on both sides of the tabletop in the short direction, and the second support leg has a movable contact body that is slidably held by the contact body and contacts the underside of the tabletop and two legs that are suspended from the movable contact body and arranged on both sides of the tabletop in the short direction. Materials for the first support leg and the second support leg include metals such as iron, aluminum, and titanium, alloys of these metals, carbon fiber, etc., but are not limited to these, and any material that has enough strength to support the tabletop and function as a table can be used.

[0014] The movable abutment body only needs to be slidably held (connected) to the abutment body so that it can move in the longitudinal direction (horizontal direction) of the tabletop, and the respective shapes and configurations of the abutment body and the movable abutment body, as well as the method of connecting (fixing) the abutment body and the movable abutment body, etc., can be selected appropriately. A specific configuration of the abutment body is preferably one having two cross sections arranged parallel to the longitudinal direction of the tabletop and a connecting section connecting one longitudinal side of the two cross sections, and a configuration of the movable abutment body is preferably one having two movable cross sections arranged parallel to the longitudinal direction of the tabletop and slidably held on each cross section, and a connecting section connecting the other longitudinal side of the two movable cross sections.

[0015] For the horizontal section, the movable horizontal section and the connecting section, square pipes or round pipes are preferably used, but are not limited thereto. The length of one side of the cross section of the square pipe and the diameter of the cross section of the round pipe are preferably about 30 to 50 mm, but are not limited to these ranges and are appropriately selected depending on the size (total length and width) and weight of the table. The cross section of the square pipe may be square or rectangular. It is preferable that the length of the cross section is, for example, about 800 to 1200 mm, the length of the movable cross section is, for example, about 600 to 1000 mm, the length of the connecting section is, for example, about 400 to 800 mm, and the spacing between the cross sections is, for example, about 200 to 600 mm, but they are not limited to these ranges and can be selected appropriately depending on the size and weight of the corresponding table, etc.

[0016] In order to slidably hold each movable cross section relative to each cross section, each cross section and each movable cross section are arranged adjacent to each other (so that their sides abut each other), and multiple female screw holes are formed on one side of each cross section (the side of each movable cross section), and multiple insertion holes are formed passing through each movable cross section in the width direction. The intervals between the female screw holes and the insertion holes are preferably about 100 mm, but are not limited to this and can be selected appropriately. The intervals between the female screw holes and the insertion holes do not need to be the same, and it is sufficient that the multiple female screw holes and the multiple insertion holes are arranged so that they overlap each other in a side view when each movable cross section is slid relative to each cross section. The number of female screw holes and insertion holes is selected appropriately depending on the length of each cross section and movable cross section, and the intervals between the female screw holes and the insertion holes.

[0017] The spacing between the first and second support legs is adjusted so that the multiple female screw holes of each cross section and the multiple insertion holes of each movable cross section overlap in a side view, and fixed male screws are selectively inserted into the multiple insertion holes of each movable cross section and the tip of the fixed male screw is screwed into the female screw hole that overlaps with the insertion hole, thereby enabling each cross section and each movable cross section to be securely fixed. A hexagonal bolt with a nominal diameter of about M8 is preferably used as the fixed male screw, but the size (nominal diameter) and type of the bolt are not limited to this and can be selected as appropriate. Each horizontal section and each movable horizontal section are preferably fixed with fixed male screws at two or three locations, but may be fixed at four or more locations. The spacing (attachment spacing) of the fixed male screws can be selected appropriately, and may be equal or unequal.

[0018] When the cross section is made of a square or round pipe, a female screw hole can be formed by drilling pilot holes at key points on the cross section and driving in a blind nut (also called a nut rivet). Also, if the square or round pipe has a sufficient thickness, a female screw hole can be formed directly with a tap. When the movable cross section is constructed of a square pipe or a round pipe, the inside of the movable cross section is hollow, so that holes can be drilled in both sides (side walls) to function as insertion holes.

[0019] In order to hold each movable cross section slidably relative to each cross section, instead of the multiple female screw holes formed on one side (the movable cross section side) of each cross section in the above configuration, multiple fitting holes can be formed that penetrate each cross section in the width direction, and fixing pins can be inserted instead of fixed male screws to fix each cross section and each movable cross section by pin fitting. When the horizontal section is constructed of a square pipe or a round pipe, the inside of the horizontal section is hollow, so that holes can be simply drilled in both sides (side walls) to function as fitting holes.

[0020] Anti-slip materials are attached to the upper surfaces of the contact body and the movable contact body at key points. A mat made of an adhesive foam material is preferably used as the anti-slip material, but the material is not particularly limited as long as it can prevent the top plate from shifting by tightly contacting the contact body and the top plate, and the movable contact body and the top plate. The shape, size, number and arrangement of the anti-slip materials are selected appropriately.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a leg structure according to one embodiment of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to this embodiment.

[0022] Here, Fig. 1 is a front view of an example of a table leg structure according to an embodiment of the present invention in use. Fig. 2 is a side view of an example of a table leg structure according to an embodiment of the present invention in use. Fig. 3 is a bottom view of an example of a table leg structure according to an embodiment of the present invention in use. Fig. 4 is a plan view of a table leg structure according to an embodiment of the present invention.

[0023] As shown in Figs. 1 to 4, a table leg structure 1 according to an embodiment of the present invention supports a tabletop 10, which is a single rectangular plate in plan view, to form a table 11, and includes a first support leg 12 supporting one side of the tabletop 10 in the longitudinal direction, and a second support leg 13 connected to the first support leg 12 so as to be spaced apart from each other and supporting the other side of the tabletop 10 in the longitudinal direction. The first support leg 12 includes a contact body 14 that contacts the bottom surface of the tabletop 10, and two legs 15 that are hung from the contact body 14 and disposed on both sides of the tabletop 10 in the lateral direction. The second support leg 13 includes a movable contact body 17 that is slidably held by the contact body 14 and contacts the bottom surface of the tabletop 10, and two legs 18 that are hung from the movable contact body 17 and disposed on both sides of the tabletop 10 in the lateral direction.

[0024] As shown in FIG. 3, the abutment body 14 has two horizontal sections 19 arranged parallel to the longitudinal direction of the top plate 10, and a connecting section 20 connecting one side of the two horizontal sections 19 in the longitudinal direction. In addition, the movable abutment body 17 has two movable horizontal sections 21 arranged parallel to the longitudinal direction of the tabletop 10 and slidably held on each horizontal section 19, and a connecting section 22 connecting the other longitudinal sides of the two movable horizontal sections 21. In this way, each cross portion 19 of the abutment body 14 and each movable cross portion 21 of the movable abutment body 17 are arranged parallel to the longitudinal direction of the tabletop 10, and the connecting portion 20 of the abutment body 14 and the connecting portion 22 of the movable abutment body 17 are arranged parallel to the transverse direction of the tabletop 10.By simply placing the tabletop 10 on the upper surface of the abutment body 14 and the movable abutment body 17, the tabletop 10 can be stably supported by the first support leg 12 and the second support leg 13.

[0025] The horizontal section 19, the connecting section 20, the movable horizontal section 21 and the connecting section 22 are all rectangular pipes having a square cross section with one side measuring 45 mm, the horizontal section 19 is 1200 mm long, the movable horizontal section 21 is 1000 mm long, the connecting sections 20 and 22 are 640 mm long, and the spacing between the horizontal sections 19 is about 300 mm. The total length (longitudinal length) of the tabletop 10 is 1500 mm.

[0026] 3 and 4, the table leg structure 1 has a plurality of female screw holes 24 formed on one side of each horizontal frame 19, and a plurality of insertion holes 25 penetrating each movable horizontal frame 21 in the width direction. The table leg structure 1 has a plurality of fixing male screws 26 that are selectively inserted into the multiple (three in this case) insertion holes 25 of each movable horizontal frame 21 and selectively screwed into the multiple female screw holes 24 of each front horizontal frame 19 to fix each horizontal frame 19 and each movable horizontal frame 21. This makes it possible to firmly fix each horizontal frame 19 and each adjacent movable horizontal frame 21, and to reliably support the tabletop 10 by maintaining a constant distance between the first support leg 12 and the second support leg 13.

[0027] The number of female screw holes 24 formed in each horizontal section 19 and the number of through holes 25 formed in each movable horizontal section 21 are each nine, and the arrangement intervals between them are 100 mm. The female screw holes 24 are M8 prism nuts attached to one side of the horizontal section 19, and the fixed male screws 26 are M8 hexagonal bolts with a nominal length of 60 mm.

[0028] As shown by hatching in Fig. 4, anti-slip materials 27 are attached to key locations (three locations in this example) on the upper surfaces of the contact body 14 and the movable contact body 17. The anti-slip materials 27 are mats made of an adhesive foam material and used to fasten furniture, etc. By locating the anti-slip materials 27 above each of the legs 15, 18 and in the longitudinal center of each of the connecting parts 20, 22, the load received from the tabletop 10 can be reliably supported and the tabletop 10 can be effectively prevented from shifting out of position.

[0029] Next, another example of the usage state of the table leg structure 1 according to the embodiment of the present invention will be described. FIG. 5 is a bottom view showing another example of the use state of the leg structure 1 for a table according to an embodiment of the present invention. The total length (length in the longitudinal direction) of the tabletop 10a shown in Fig. 5 is 2000 mm. At this time, by sliding the movable abutment body 17 against the abutment body 14 from the state shown in Fig. 3 to widen the gap between the first support leg 12 and the second support leg 13, and fixing the female screw holes 24 and the insertion holes 25 in the area where the horizontal sections 19 and the movable horizontal sections 21 overlap with the fixing male screws 26, it is possible to stably support the tabletop 10a, which has a total length longer than the tabletop 10. In this table leg structure 1, by adjusting the distance between the first support leg 12 and the second support leg 13, it is possible to accommodate table tops with total lengths of up to 1400 to 2100 mm.
