The specific embodiment
Below, with reference to accompanying drawing, embodiment is described.In addition the summary of the invention that the embodiment shown in, does not record claim plays any restriction effect.The solution of the invention that in addition,, the full content of the represented formation of embodiment is not limited to record as claim is necessary.
The invention discloses a kind of folding seat, by increasing by two waist relying parts, upon deployment, waist relying part can fit with the physiological curve of the waist of human body, plays the effect of supporting waist, thereby slows down user's waist ache.
Folding seat as shown in Fig. 2-Figure 11, this folding seat comprises: the first backing tube 101 that is arranged with the first through hole support 111; Be arranged with the second backing tube 102 of the second through hole support 112; The first attaching parts that connect the first backing tube 101 and the second backing tube 102; The first cross pipe that connects the first upper bracket 117 and the first backing tube 101; The second cross pipe that connects the second upper bracket 118 and the second backing tube 102; The second attaching parts that connect the first upper bracket 117 and the second upper bracket 118; With the oxford that is set in described the first backing tube 101, the second backing tube 102 and the second attaching parts; Also comprise be symmetrical arranged and when folding seat is launched between the first backing tube 101 and the second backing tube 102 can with the first waist relying part and the second waist relying part of waist.
Upon deployment, oxford launches folding seat completely, and wherein, the first backing tube and the second backing tube support the backrest that oxford forms folding seat, and the oxford between the first cross pipe, the second cross pipe and the second attaching parts forms the seat of folding seat.
Folding seat in the embodiment of the present invention has newly increased the first waist relying part and the second waist relying part, and all can fit with lumbar curve in two waist relying parts.During use, folding seat is launched, and under the effect of the first waist relying part and the second waist relying part, there is boss in oxford, the position of projection can hold up user's waist just, thereby can prevent to a certain extent that waist is recessed, reaches the object that slows down waist ache.
The first attaching parts in the embodiment of the present invention and the second attaching parts, can be for example tube connector for the parts that are rigidly connected, these tube connector two ends are separately fixed on the first backing tube 101 and the second backing tube 102, now, the first backing tube 101 and the second backing tube 102 can not be realized and draw action in, can only realize the gathering action of the first cross pipe and the second cross pipe.In addition, the first attaching parts and the second attaching parts can also be for launching and draw in the parts of function, it is for example the overlapped hinged brace in end, one of them brace and the first backing tube 101 are hinged, and another one brace and the second backing tube 102 are hinged, the position that brace joins mutually, there is the elastomeric element that can clamp, when needs draw the first brace and the second brace in, outwards break elastomeric element into two with one's hands, two braces just can be realized gathering.
The first cross pipe in the embodiment of the present invention can be similar to the cross pipe in background technology with the second cross pipe structure, can also be according to concrete application scenarios, the shape of conversion cross pipe, for example, one of them cross pipe is designed to have arcuate structure, can plays the effect of handrail.The embodiment of the present invention preferably adopts the structure in background technology, this first cross pipe comprise that middle part is hinged first on cross pipe 105 and first time cross pipe 106, the first top and the first through hole support 111 of cross pipe 105 hinged; It is hinged that the top of first time cross pipe 106 is provided with bottom and first backing tube 101 of 117, the first times cross pipes 106 of the first upper bracket;
The second cross pipe comprise that middle part is hinged second on cross pipe 107 and second time cross pipe 108, the second top and the second through hole support 112 of cross pipe 107 hinged; It is hinged that the top of second time cross pipe 108 is provided with bottom and second backing tube 102 of 118, the second times cross pipes 108 of the second upper bracket.
Hinged between rod member and rod member can be realized by self structure in the bottom of above-mentioned cross pipe and backing tube, can also realize hinged between rod member and rod member by support, for example: the bottom of first time cross pipe 106 is hinged by the first lower carriage 113 and the first backing tube 101; On first, the bottom of cross pipe 105 is fixed with the second lower carriage 114; The bottom of second time cross pipe 108 is hinged by the 3rd lower carriage 115 and the second backing tube 102; On second, the bottom of cross pipe 107 is fixed with the 4th lower carriage 116.
When the first cross pipe is when being connected by above-mentioned support on the second cross pipe, above-mentioned the first attaching parts comprise middle part be hinged first on tube connector 103 and first time tube connector 104, on first, the top of tube connector 103 and the first through hole support 111 are hinged, and bottom and the 3rd lower carriage 115 of tube connector 103 is hinged on first; The top of first time tube connector 104 and the second through hole support 112 are hinged, and the bottom of first time tube connector 104 and the first lower carriage 113 are hinged;
The second attaching parts comprise middle part be hinged second on tube connector 109 and second time tube connector 110, on second, the top of tube connector 109 and the first upper bracket 117 are hinged, on second, the bottom of tube connector 109 and the 4th lower carriage 116 are hinged, the top of second time tube connector 110 is connected hinged with the second upper bracket 118, the bottom of second time tube connector 110 is connected hinged with the second lower carriage 114.
Above-mentioned each supporting structure can be the same or different, and in the embodiment of the present invention, preferably above-mentioned each rack making is become to same structure, can improve the versatility of support, when one of them support damages, can follow and change at any time.In the main body of above-mentioned each support, be provided with the installing hole that holds the first backing tube 101, and for the articulated section of hinged each pipe fitting, have two articulated sections on each support, two articulated sections are 90 ° of layouts, and on articulated section, have the through hole that holds rivet.The first lower carriage 113 that is arranged on the first backing tube 101 bottoms of take is example, the first backing tube 101 is fixed in the installing hole of the first lower carriage 113, the first lower carriage 113 is hinged on the first articulated section of the first lower carriage 113, and first time tube connector 104 is hinged on the second articulated section of the first lower carriage 113.Take that the 4th lower carriage 116 is installed is example, because the 4th lower carriage 116 is without backing tube is installed, so corresponding installing hole is idle, on first articulated section and second of the 4th lower carriage 116, the bottom of tube connector 109 is hinged, and on second articulated section and second of the 4th lower carriage 116, the bottom of cross pipe 107 is hinged.
Adopt in above-mentioned second attaching parts of this structure, the first handrail position is extended on the top of tube connector 109 on second, and the second handrail position is extended on the top of second time tube connector 110.
The first corresponding upper bracket 117 and the second upper bracket 118 are processed possesses the articulated section hinged with each cross pipe, also has the groove of tube connector or second time tube connector in picking-up second.
