Description

Folding sled

Technical field

The utility model relates to stationery sports goods, particularly folding sled.

Background technology

Sled is that people participate in the conventional instrument of winter sports winter.Conventional sitting sledge entirety is ship shape, has difficult, the problem that storage area is large.

Utility model content

The purpose of this utility model is the sled that a kind of novel foldable will be provided, and can solve above-mentioned prior art problem.

According to an aspect of the present utility model, a kind of folding sled is provided, comprise two skids, and two seats that are hinged, be arranged in parallel, skid is connected by fold mechanism with seat; Fold mechanism comprises that one end is fixedly connected with skid, the other end and hinged the first support bar of seat, and one end and skid is hinged, the seat of the other end and opposite side is hinged the second support bar.

Folding sled of the present utility model is provided with fold mechanism, when use, can open, and sled entirety is ship shape; When collection or carrying, the skid of both sides and seat can be drawn in, be flat, be convenient to carrying, and it be little to take up room.

In some embodiments, also comprise retaining mechanism, retaining mechanism comprises that one end is hinged on the Fastener on the seat in left side, and the elastomeric element that one end is connected with Fastener, the other end is connected with second support bar in left side; The second support bar is provided with buckle, and Fastener is provided with the draw-in groove mating with buckle.Thus, using in sled slides, can guarantee that the relative position of skid and seat is firm, be unlikely to run-off the straight in the process sliding and cause causing danger.

In some embodiments, Fastener is provided with the jut vertical with elastomeric element elastic recovery direction.Thus, can make in drawing skid and seat in easy to operate.

In some embodiments, elastomeric element is tension spring, and buckle is positioned at the outside, middle part of tension spring.Thus, there is simple in structure, compact effect.

In some embodiments, the cross section of the second support bar is I shape.Thus, can guarantee the intensity of the second support bar, also can save material, alleviate the weight of sled.

In some embodiments, the cross section of the first support bar is half shaped as frame, and inner width is greater than the width of two the second support bars; One end of the second support bar is hinged on the first support bar inner side.Thus, after skid and seat draw in, the second support bar can be collected in the first support bar inside, makes the rear structure of sled gathering compact.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1～Fig. 6 has schematically shown according to the structure of the folding sled of a kind of embodiment of the present utility model.

As shown in Fig. 1～Fig. 6, this folding sled comprises two skids 3, two seats 2, fold mechanism 1 and retaining mechanisms.

Two skids 3 are separately positioned on the both sides, bottom of sled, and front end is the arc being upturned.

Two seats 2 are hinged, are set in parallel in the top of sled.In the present embodiment, each seat 2 comprises the seatpost 22 of two strips that be arranged in parallel, and the front end of seatpost 22 and the front end of skid 3 that are positioned at outside are hinged.Two seatposts 22 on same seat 2 are fixedly connected with by connecting rod 21.The connecting rod 21 of two seats 2 in left and right is hinged.

The fold mechanism 1 that passes through of skid 3 and seat 2 is connected.Fold mechanism 1 comprises the first support bar 11 and the second support bar 12.One end of the first support bar 11 is fixedly connected with skid 3, the connecting rod 21 of the other end and seat 2 is hinged.One end of the second support bar 12 and skid 3 are hinged, the connecting rod 21 of the seat 2 of the other end and opposite side is hinged.

The cross section of the second support bar 11 is I shape.The cross section of the first support bar 11 is half shaped as frame, and inner width is greater than the width of two the second support bars 12; One end of the second support bar 12 is hinged on the first support bar inner side 11.

In the present embodiment, on fold mechanism 1, be also provided with retaining mechanism.Retaining mechanism comprises Fastener 41, elastomeric element 42, buckle 44, draw-in groove 45.One end of Fastener 41 is hinged on the connecting rod 21 of seat 2 in left side, and one end of elastomeric element is connected with Fastener 41, second support bar 12 companies in the other end and left side; Buckle 44 is arranged on second support bar 12 in left side, and draw-in groove 45 is arranged on the edge of Fastener 41, mates with buckle 44.On Fastener 41, be also provided with the jut vertical with the elastic recovery direction of elastomeric element 43.

In the present embodiment, elastomeric element 42 is tension springs.In other embodiments, elastomeric element 42 can also be compression spring or torsion spring etc.

When using this sled, the seatpost in outside 22 is pulled outwardly, makes sled entirety be the state of the ship shape of Fig. 5, then the draw-in groove on Fastener 41 45 is blocked to buckle 44.Due to the effect of tension spring, Fastener 41 blocks buckle 44 all the time, makes the second support bar 12 keep relatively-stationary position with seat 2.Because triangle is stable structure, it is stable that sled in use also can holding structure.

When folding this sled, first with hand to elastomeric element 42 reply parties to opposite direction pull the jut 43 on Fastener 41, make draw-in groove 45 depart from buckle 44, again the seatpost 22 that is positioned at outside is pushed away inward, as shown in Figure 3 and Figure 4, until the parts of the sled left and right sides close up, as shown in Figure 6.

Above-described is only embodiments more of the present utility model, not the restriction to the utility model design.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
