The 2 and 3 show the whole form of the portable chair according to the invention.
As in the 2 and 3 shown, the portable chair according to the invention comprises:
connectors 10 , which are respectively arranged on the left and on the right side of the chair; a central support frame 20 which the left and right connectors 10 connects with each other; front and rear frame legs 30 and 40 whose foot ends separately with the lower front and rear outer peripheral surfaces of the respective connecting pieces 10 are connected and whose free ends are formed as extending radially in the direction of the bottom surface; front and rear frame bars 50 and 60 whose foot ends separately with the upper front and rear outer peripheral surfaces of the respective connecting pieces 10 are connected and whose free ends are formed as extending radially in the direction of the sky; and a fabric web 100 connected to the free ends of the front and rear frame bar 50 and 60 connected is.
In this embodiment, the fabric web 100 Bags 110 on which the separate recording of the free ends of the front and rear frame bars 50 and 60 serve. The joining and separating operation between the fabric web 100 and the frame bars 50 and 60 can be realized in a variety of forms using a tape, a clip, an attached fabric and the like.
The fabric web 100 has a narrow surface and a simple structure, which is suitable to wear and encase the buttocks, thighs and waist of a user. For this structure, the fabric web 100 a seating area section 101 which is curved and recessed in shape to support and envelop the buttocks, thighs and waist of a seated user, and side surface portions 102 which the left and the right side of the seat portion 101 limit.
The fabric web 100 may be formed such that the seat surface portion 101 and the side surface portions 102 are formed as separate pieces and that they are sewn together by connecting bands.
Since the portable chair according to the invention can be folded, with the front and rear frame legs 30 and 40 and the front and rear frame bars 50 and 60 from the connectors 10 be separated and the fabric web 100 From this, the volume of the portable chair is small, so that the portable chair can be comfortably transported.
In addition, since the portable chair according to the invention is formed in a structure in which the foot ends of the frame parts 30 . 40 . 50 and 60 radially with the two central connectors 10 be connected on both the left and the right side of the chair, so that the load can be carried, and the connectors 10 also through the central support frame 20 instead of the existing structure in which the intersections of the frame are perforated and hinge pins are passed therethrough, resulting in a weak structure, the portable chair can be held in contrast in a position in which a reduction in the rigidity of the frame does not matter and the structural rigidity is excellent and stable.
If the frame parts 20 . 30 . 40 and 50 are formed of a highly elastic aluminum alloy, the rigidity and elasticity of the alloy material can be utilized. For this reason, the structural rigidity of the frame can be further improved, and the frame can be made thinner and lighter in weight. In this case, when the front and rear frame legs picking up the load 30 and 40 are short, the flexural rigidity increases, so that the frame can be thinner and lighter in weight.
The fabric web 100 Not only can the buttocks and thighs of the user sitting on the seat portion receive, but also the waist of the user in an inclined state, while maintaining excellent comfort and stability for a long period of time. In addition, since the side surface portion 102 to a predetermined degree higher than the buttocks left and right, as well as the lateral surfaces of the thighs, not only is the practical stability given, but also mental gives the impression of stability.
In addition, the volume of the folded portable chair can be further reduced since even the fabric web 100 can be separated, and the installation and separation of the portable chair can be easily performed due to the structure in which the free ends of the front and rear frame bars 50 and 60 in the pockets 110 be introduced.
The 4 to 9 are illustrations which explain in detail the structure of the frame parts according to the invention.
As in the 4 to 6 shown is the central support frame 20 in both the left and right connectors 10 fitted. The foot ends of the frame legs 30 and 40 and the frame bars 50 and 60 are in the outer peripheral surfaces of the connecting pieces 10 fitted in the manner of a thru-axle / bore connection.
Both ends of the central support frame 20 are connected to both the left and right connectors 10 by means of an elastic cord 70 , In the same way, the front and rear frame legs 30 and 40 and the front and rear frame bars 50 and 60 with the connectors 10 by means of an elastic cord 80 connected. Because the elastic cords 70 and 80 the frame parts in the direction of the connectors 10 The frame parts may be barred from being accidentally disconnected from the connectors 10 Being disconnected while the portable chair is installed, and the frame parts can be prevented from getting lost and can be evenly arranged when the portable chair is folded.
To connect the elastic cords 70 and 80 To simplify are bound stoppers 75 and 85 intended. The ends of the elastic cords 70 and 80 are with the bound stoppers 75 and 85 connected. The bound stoppers 75 for the central support frame 20 be in the outer ends of the connectors 10 introduced. The bound stoppers 85 for the frame legs 30 and 40 and the frame bars 50 and 60 are each with the free ends of the frame parts 30 . 40 . 50 and 60 connected.
If the central support frame 20 has a hollow tube shape is the elastic cord 70 formed by the interior of the central support frame 20 to be guided, and both the connectors 10 as well as the bound stoppers 75 are in the outer ends of the connectors 10 introduced.
When the frame legs 30 and 40 and the frame bars 50 and 60 are formed in a hollow tube shape, the elastic cord 80 formed by the interior of the frame parts 30 . 40 . 50 and 60 to be guided, and the bound stopper 85 is inserted in the free end of the frame parts 30 . 40 . 50 and 60 ,
In the meantime, the front frame bars can 50 , the rear frame bars 60 or both frame parts 50 and 60 be configured in a manner in which two or more frame bar units are connected to each other in the axial direction. In this embodiment, only the rear frame bar is 60 configured such that two separate frame bar units 60a and 60b are interconnected with each other in the axial direction.
It is desirable to have the free ends of the front and rear frame support members 30 and 40 , which land on the ground surface, with protective caps 90 to provide. Although not shown in the figures, the protective caps may be connected to the free ends of the front and rear frame bars 50 and 60 be connected. The protective caps 90 allow the frame parts 30 and 40 can reliably land on the ground surface and protect the free ends of the frame parts 30 and 40 so that damage and deformation of the like can be prevented. In addition, the protective caps prevent dirt or debris from entering the free ends of the frame parts.
The 7 to 9 show the structure like the frame parts 20 . 30 . 40 . 50 and 60 separately with the connectors 10 are connected and the installation form of elastic cords 70 and 80 ,
As in the 7 to 9 is shown on the surfaces of the inside of the connectors 10 a connection hole provided, and the end of the central support frame 20 can be rotatably inserted into this connection hole. The elastic cord 70 extends through the connection hole 11 of the connector 10 therethrough. Even if the end of the central support frame 20 rotatably in the connection hole 11 of the connector 10 is inserted, is not to be feared that the connectors 10 arbitrarily from the central support frame 20 be disconnected as the elastic cord 70 the connectors provided on both sides of the portable chair 10 pulls inwards.
If the end of the central support frame 20 with a connection hole 11 of the connector 10 is rotatably connected (ie, to an extent in which the end can be rotated by the action of a user), both the left and the right connector 10 to be turned around. This means that both connectors 10 at a different angle relative to the central support frame 20 can be turned. In this way, both connectors 10 when there is a height difference to the ground surface where both the front and the rear frame leg 30 and 40 land or both the left and the right frame leg 30 and 40 land, rotate accordingly relative to the central support frame 20 so that the frame legs 30 and 40 land all stable on the ground
In addition, the outer peripheral surface of the connector 10 with radial connection holes 12 provided, and the foot ends of the front and rear frame legs 30 and 40 and the front and rear frame bars 50 and 60 are separate in the connection holes 12 plugged in. Even if the foot ends of the frame legs 30 and 40 and the frame bars 50 and 60 rotatable in the communication holes 12 the connectors 10 not be feared that there is an arbitrary separation of the frame parts 30 . 40 . 50 and 60 from the connectors 10 comes, because the elastic cords 80 the frame parts 30 . 40 . 50 and 60 in the direction of the central connector 10 pull,
In the case that the frame parts 30 and 40 and the frame bars 50 and 60 separated from each other in the connectors 10 are inserted through the insertion holes 12 and the frame legs 30 and 40 and the frame bars 50 and 60 are designed as hollow tubes, the elastic cords 80 be formed by the interior of the respective frame parts 30 . 40 . 50 and 60 and the connectors 10 to be guided.
Each of the front frame legs 30 , the rear frame legs 40 , the front frame bars 50 and the rear frame bars 60 can be connected to any frame part except itself by an elastic cord 80 through the connectors 10 passes through. This means that of the frame parts 30 . 40 . 50 and 60 , two arbitrary, in the circumferential direction adjacent or diagonally opposite frame parts can be interconnected by means of an elastic cord 80 passing through the connectors 10 passes through. In the 8th and 9 are the opposing frame parts, ie the front frame leg 30 and the rear frame bar 60 lie opposite each other and the rear frame leg 40 and the front frame bar 50 lie opposite each other, interconnected by an elastic cord 80 , In contrast, the adjacent in the circumferential direction frame parts 30 - 40 / 50 - 60 or 30 - 50 / 40 - 60 be connected to each other.
With the configuration described above, the elastic cord 80 Easy to install and easy to be in the structure because of the elastic cord 80 not with the connector 10 connected or must be fixed to this.
As in the 10 and 11 shown when the frame parts 30 . 40 . 50 and 60 from the connection holes 12 the connectors 10 can be pulled to be separated from it, the elastic cord can 80 expand, and the frame parts can be folded, while being on the central support frame 20 can be aligned so that the volume of the portable chair can be made very small overall. The fabric web 100 (please refer 1 and 2 ) is separated before the frame parts are separated.
As in 12 shown as the portable chair can be folded into a neat shape with a small volume in a way that the separated fabric web 100 folded and wrapped around the frame parts, the portable chair can be easily transported and accommodated.
Since the portable chair according to the invention has a structure in which the foot ends of the respective frame parts are radially connected to the two central, provided on both the left and on the right side of the chair joints, so as to receive the load, and both links are supported by the central support frame, there is no fear that the rigidity of the frame will decrease, the structural rigidity is rather excellent and the chair may land on the ground surface in a stable position.
In addition, since the portable chair according to the invention can be collapsed with the front and rear frame legs and the front and rear frame bars separated from the connectors and the fabric panel separated therefrom, the volume of the portable chair is small, making the portable chair comfortable can be transported.
In addition, the fabric sheet comfortably wears and covers the buttocks, thighs and waist of the user, though it has a small area and a simple structure.
In addition, since the frame legs and the frame bars are separately connected to the connectors and pulled by the elastic cords and the bound stoppers toward the central connectors, the portable chair according to the invention can be realized as a whole together with the Connecting structure of the frame parts, and can be easily folded and unfolded.
