  • Patent number: 12168883
    Abstract: A tent is formed from a tarpaulin and support rods that form an external support structure. The support rods are radially connected to a top-middle connecting piece in the center of the top of the tent to form a tent ceiling. The tent ceiling is supported and maintains its shape by elastically reverse positioning of at least three support rods. The tarpaulin has a breach formed in the center. The top-middle connecting piece is connected with the tarpaulin on the top surface of the tent through a first connecting sheet. The first connecting sheet encloses the top-middle connecting piece and the breach at the center of the top of the tent to form a folding reserved space. The folding reserved space makes up the difference between the length of the support rods and the length of the fabric of the tent ceiling.

  • Patent number: 12122440
    Abstract: A foldable cart has a stabilizing handle device, which includes a connecting seat. The connecting seat has a connecting groove and two connecting rods of the foldable frame of the foldable cart are pivotally connected to the connecting seat in the connecting groove. A pulling rod mechanism is pivotally connected with the connecting seat. The connecting seat has a fixing strut that extends between the connecting seat and the foldable frame. When the cart frame is folded, the two connecting rods rotate about their pivot connections with the connecting seat, so that the two connecting rods approach each other. The connecting seat is fixedly connected to the fixing strut and a pivot point on the front side of the foldable frame so that an angle between the two remains fixed, which prevents the pulling rod mechanism from toppling left and right.
