Description

[Technical field]

[0001] The present invention relates to a platform having a telescopic structure. [Background technology]

[0002] Conventionally, there are tables that can be stored compactly and are easy to carry, such as folding tables. Conventional folding tables and assembly tables are designed with a focus on compact storage and ease of carrying.

[0003] For example, the folding chair-cum-small table described in Patent Document 1 includes a pair of roughly U-shaped frames connected in a roughly X-shape when viewed from the side so that the legs can be opened and closed, a sheet material stretched between the upper edges of the pair of frames, and a top plate that is detachably hung between the upper edges of the frames from above the sheet material. This folding chair-cum-small table doubles as a chair and is easy to carry. With this structure, the table can be used as a chair and is also easy to carry. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-264016 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with normal folding tables, the structure required for folding is complex and the number of parts tends to be large, making them prone to breakdowns and loose parts. Also, the large number of parts and complex structure make it time-consuming and tedious to use and store. Furthermore, frequent deformation and storage can cause durability issues, especially in the joints and moving parts.

[0006] Due to these issues, there is a demand for a new type of table-like stand that is simple in structure, durable, and requires little effort to use. [Means for solving the problem]

[0007] (1) The telescopic structure base of the present invention is an telescopic structure base including a plurality of consecutive windings, each of which includes a horizontal portion extending in a generally straight line, a first leg extending in a generally vertical direction and supporting one end of the horizontal portion, a second leg extending in a generally vertical direction and supporting the other end of the horizontal portion, a connecting portion extending from one side of the first leg of one winding portion to the second leg of an adjacent winding portion, and a connecting portion extending from one side of the first leg to the second leg of an adjacent winding portion, and in each winding portion, the angle formed by the horizontal portion and the connecting portion changes, thereby changing the spacing between adjacent horizontal portions and thereby telescopically expanding and contracting.

[0008] The telescopic platform is made up of a number of successive windings that are connected together to form the platform shape. The angle between the horizontal section and the connecting section of the successive windings changes, and the spacing between the windings changes, allowing the telescopic platform as a whole to expand and contract.

[0009] (2) In the above-mentioned extendable structure platform, the horizontal portion is the upper side and the connecting portion is the lower side, so that the horizontal portion forms the top surface.

[0010] According to this extendable structure platform, the horizontal portion forms a plane, forming a table having a plane.

[0011] (3) In the telescopic structure base of (2) described above, the plurality of winding portions are arranged radially, and the plurality of horizontal portions form a circular top surface.

[0012] According to this extendable structure base, the extendable structure base forms a circular table having a circular top surface.

[0013] (4) In the telescopic structure base of (3) described above, among the plurality of winding portions, the winding portion at one end and the winding portion at the other end are connected to maintain the winding portions arranged radially.

[0014] With this extendable structure base, the radially arranged windings are maintained by connecting the windings at one end with the windings at the other end, so that the shape of a circular table can be maintained.

[0015] (5)) In the telescopic structure base of (2) described above, the multiple winding portions are arranged in a straight line, so that the multiple horizontal portions form a rectangular top surface.

[0016] According to this extendable structure base, the extendable structure base forms a rectangular table having a rectangular top surface. Effect of the Invention

[0017] According to the present invention, a new type of platform is provided which has a simple structure, is durable, and requires less effort in use. [Brief description of the drawings]

[Figure 9]FIG. 7 shows a side view of the circular table shown in FIG. 6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the extendable structure table 1 according to the embodiment of the present invention will be described with reference to the drawings. In the description of this embodiment, the arrow a shown in each drawing will be the upward direction (vertical direction), the double-headed arrow b will be the front-rear direction (first horizontal direction), and the double-headed arrow c will be the width direction (second horizontal direction).

[0020] The extendable structure base 1 according to the embodiment of the present invention forms a circular table. The extendable structure base 1 will be described in detail with reference to Figs. 1 to 8. As described below, the extendable structure base 1 has continuous winding portions R, and in each winding portion R, the angle formed by the horizontal portion 30 and the connecting portion 40 changes, changing the interval between adjacent horizontal portions 30, thereby expanding and contracting or deforming linearly or circumferentially.

[0021] First, the telescopic structure base 1 shown in Figs. 1 to 5 includes a plurality of winding portions R, and is in a state in which the winding portions R are arranged adjacent to each other to such an extent that they are in contact with each other, that is, in a contracted state.

[0022] 1 to 4, the telescopic structure base 1 has horizontal parts 30 of successive winding parts R arranged adjacent to each other to form a rectangular upper surface. Therefore, the telescopic structure base 1 has horizontal parts 30, first legs 10, second legs 20, and connecting parts 40, which will be described later, arranged adjacent to each other. In this embodiment, the telescopic structure includes 28 winding parts R.

[0023] 5, each winding portion R includes a horizontal portion 30 extending in a substantially linear manner, a first leg portion 10 extending in a substantially vertical direction and supporting one end of the horizontal portion 30, a second leg portion 20 extending in a substantially vertical direction and supporting the other end of the horizontal portion 30, and a connecting portion 40 extending from one side of the first leg portion 10 of one winding portion R to the second leg portion 20 of another adjacent winding portion R. Each winding portion R has a substantially linearly symmetrical shape.

[0024] The first leg 10 has a first vertical straight portion 11 extending vertically from one end of the horizontal portion 30, a first horizontal straight portion 12 extending horizontally from the first vertical straight portion 11 toward the inside of the winding portion R (toward the second leg 20), and a first folded portion 13 extending vertically upward from the first horizontal straight portion 12. The first folded portion 13 has a length dimension that is approximately 1 / 5 of the length of the first vertical straight portion 11.

[0025] The second leg 20 has a second vertical straight portion 21 extending vertically from the other end of the horizontal portion 30, a second horizontal straight portion 22 extending horizontally from the second vertical straight portion 21 toward the inside of the winding portion R (toward the first leg 10), and a second folded portion 23 extending vertically upward from the second horizontal straight portion 22. The second folded portion 23 has a length dimension that is approximately 1 / 5 of the second vertical straight portion 21.

[0026] The connecting portion 40 extends horizontally so as to connect the first folded portion 13 of the first leg 10 of one winding portion R to the second folded portion 23 of the second leg 20 of another adjacent winding portion R. By displacing the connecting portion 40 and the horizontal portion 30 to change the angle, the telescopic structure base 1 can be expanded, contracted, or deformed.

[0027] Next, the telescopic structure base 1 shown in Figs. 6 to 9 includes a plurality of winding portions R, and the winding portions R are arranged radially in a circle.

[0028] As shown in Fig. 6, in the telescopic structure base 1, the horizontal parts 30 of the multiple winding parts R are arranged approximately uniformly to form a circular horizontal surface. In detail, the multiple horizontal parts 30 are arranged at intervals on one end side of the horizontal parts 30 (the center of the circle), and the intervals form circular holes and form a circular band-shaped top surface C (see Fig. 7).

[0029] In the telescopic base 1, the first legs 10 of the multiple windings R are arranged radially in an approximately uniform manner, forming a circular, band-shaped inner leg bottom I (see FIG. 8). Also, in the telescopic base 1, the second legs 20 of the multiple windings R are arranged radially in an approximately uniform manner, forming a circular, band-shaped outer leg bottom O (see FIG. 8). The inner leg bottom I and the outer leg bottom O are formed approximately within a single horizontal plane. Furthermore, in the telescopic base 1, the connecting parts 40 of the multiple windings R are arranged radially in an approximately uniform manner, forming a circular, band-shaped groove G that is recessed one step further than the inner leg bottom I and the outer leg bottom O (see FIG. 8).

[0030] The extendable platform 1 functions as a circular table, on which items can be placed, on the circular band-shaped top surface C formed by the multiple horizontal sections 30. In addition, the inner leg bottom I and the outer leg bottom O are formed in approximately the same horizontal plane, so they function as the bottom surface and stably support the circular table.

[0031] Of the multiple connected winding parts R, the winding parts R at one end and the winding parts R at the other end are provided with a first fastener 50 and a second fastener 60. The first fastener 50 fastens the winding part R at one end and the winding part R at the other end of the multiple winding parts R so that the telescopic structure base 1 maintains its contracted state. The second fastener 60 fastens the winding part R at one end and the winding part R at the other end of the multiple winding parts R so that the telescopic structure base 1 maintains its state of forming a circular base.

[0032] In this embodiment, when the telescopic structure base 1 is contracted, the first fastener 50 connects the telescopic structure base 1 so that the contracted state is maintained by extending a hook-shaped first hook portion 51 from the winding portion R at one end toward the winding portion R at the other end and hooking the first hook portion 51 onto a hook receiving portion 52 provided on the winding portion R at the other end.

[0033] In this embodiment, the second fastener 60 connects the telescopic structure base 1 so that it maintains the state in which it forms a circular base by hooking the second hook portion 61 provided on the winding portion R at one end onto the hook receiving portion 52 provided on the winding portion R at the other end while the telescopic structure base 1 is in the state in which it forms a circular base.

[0034] In this embodiment, the telescopic structure base 1 has been described as forming a circular table. However, the telescopic structure base 1 may be configured to form tables of other shapes. For example, if multiple winding parts R are arranged in a straight line at a predetermined interval, a rectangular table can be formed.

[0035] In this embodiment, the extendable structure table 1 has been described as having the horizontal section 30 disposed on the upper side and forming the top surface C. However, the extendable structure table 1 may have the horizontal section 30 disposed on the lower side and forming the bottom surface. For example, the horizontal section 30 may be used as the bottom surface, and the first leg section 10 and the second leg section 20 may be used as support sections, allowing the table to function as a support table for supporting an item.

[0036] In this embodiment, each winding portion R of the telescopic structure base 1 includes a horizontal portion 30 extending in a substantially straight line, a first leg portion 10 extending in a substantially vertical direction and supporting one end of the horizontal portion 30, a second leg portion 20 extending in a substantially vertical direction and supporting the other end of the horizontal portion 30, and a connecting portion 40 extending from one side of the first leg portion 10 of one winding portion R to the second leg portion 20 of another adjacent winding portion R, and has a substantially line-symmetrical shape. However, each winding portion R may have another shape. For example, the first folded portion 13 and the second folded portion 23 may be made longer so that the groove G formed by the multiple connecting portions 40 becomes deeper.

[0037] In this embodiment, the first fastener 50 and the second fastener 60 are provided with a hook portion and a hook receiving portion on the winding portion R at one end and the winding portion R at the other end, respectively, to maintain the state of the telescopic structure base 1. However, the telescopic structure base 1 may be maintained in its state by other structures. For example, the telescopic structure base 1 may be fixed by other members.

[0038] In the present embodiment, the first leg 10 and the second leg 20 are described as being positioned in a substantially straight line relative to the connecting portion 40. However, the first leg 10 and the second leg 20 may be configured to have a predetermined angle relative to the connecting portion 40. For example, when viewed from above or below, the first leg 10 and the second leg 20 may be configured to form a trapezoid shape with the connecting portion 40 as the upper surface.

[0039] In this embodiment, a form in which one circular table is formed by one extendable structure base 1 has been described. However, a plurality of extendable structure bases 1 may be connected to form one circular table. For example, two extendable structure bases may be connected to form a circular table by hooking the second hook portion 61 of one extendable structure base 1 to the hook receiving portion 52 of the other extendable structure base 1. In this case, the second hook portion 61 of the other extendable structure base 1 may be hooked to the hook receiving portion 52 of one extendable structure base 1 to maintain the circular shape.

[0040] In this embodiment, the first fastener 50 and the second fastener 60 are described as maintaining the shape of the extendable structure base 1 by hooking the first hook portion 51 or the second hook portion 61 to the common hook receiving portion 52. However, the first fastener 50 and the second fastener 60 may each have a hook receiving portion, and may be hooked to the first hook portion 51 or the second hook portion 61, respectively, to maintain the shape of the extendable structure base 1.

[0041] The above describes the extendable structure base 1 according to this embodiment. However, the extendable structure base is not limited to the above embodiment, and may have other configurations within the scope of the object of the invention. [Industrial Applicability]
