Abstract: A fiberglass frame, serving as trunk frame, and including round rods, connection pieces, lateral rods, a handle rack and fastening pieces. The connection piece is provided with three connection ends, and each connection end is provided with an insertion slot. The round rod is inserted into the insertion slot in the connection piece to form a frame with the connection piece. The handle rack is located on a side of the frame and is provided with an upper fixing stand and a lower fixing stand, such that the upper fixing stand is connected to two the connection pieces on two sides through an upper lateral rod. The lower lateral rod runs through the lower fixing stand and is connected to two the connection pieces on two sides.

Abstract: The present invention discloses a slide-cover handlebar device whose handlebar body has a slide cover to conceal the button arranged in a recession of the handlebar body, and whose handlebar body also has a torsion spring. The torsion spring has a fixing ring press-fitted with a fixing protrusion of the slide cover. When the slide cover is pulled or pushed, the torsion spring is also driven to move. When the pulling or pushing force has reached a critical point, the torsion spring generates a rotation torsion force to keep on pulling or pushing the slide cover to reveal or conceal a button. The present invention can protect the button from being imprudently pressed. The torsion spring can assist the user in opening or shutting the slide cover.

Abstract: A fiberglass frame, serving as trunk frame, comprising: round rods; connection pieces; lateral rods; a handle rack; and fastening pieces. Wherein, on said connection piece is provided with three connection ends, and each connection end is provided with an insertion slot; said round rod is inserted into said insertion slot in said connection piece, to form a frame with said connection piece; said handle rack is located on a side of said frame, and is provided with an upper fixing stand and a lower fixing stand, such that said upper fixing stand is connected to two said connection pieces on two sides through an upper lateral rod, and said lower lateral rod runs through said lower fixing stand, and is connected to two said connection pieces on two sides.

Abstract: The present invention relates to a wheel assembly with a single fixing arm capable of being disposed on a luggage, the wheel assembly comprises: an assembly body, a wheel frame, a first pad, a circular plate, a ring pad, an assembly shaft, an auxiliary wheel, a bearing mechanism, and a wheel, wherein the assembly shaft being punched through assembly body, the wheel frame, the first pad, the circular plate, and the ring pad, so as to combine the assembly body and the wheel frame. The auxiliary wheel is adapted to maintain the stability of the wheel when the wheel is on a rotating state; moreover, the wheel can stop rotating when applying a force to the auxiliary wheel.

Abstract: A retractable pulling rod control device, wherein, a concave portion and a through hole are provided on a plug, and a link piece is disposed on said concave portion, such that said link piece is provided with a plurality of protrusion portions exposed outside said through hole; and a first and a second T-shaped link pieces are installed in said through hole and are fastened to each other, said first T-shaped link piece is provided with a first protrusion block, and said second T-shaped link piece is provided with a groove and a second protrusion block, said protrusion portion is fastened correspondingly to said groove, and said protrusion portion is able to slide in said groove in bringing said first and said second T-shaped link pieces into motion in said through hole, hereby achieving the effect of controlling the extension and retraction of each section of a pulling rod.

Abstract: A shock-proof drag wheel is disclosed. Wherein, on its base is provided with a fixed axis and an indentation portion, a connection rod is disposed on said fixed axis and is connected to an elastic body, and it is swayed and vibrated around said fixed axis. A central axis passes through said connection rod and is located in said indentation portion, and said drag wheel is provided in said indentation portion. When said drag wheel is made to move, the spring force of said elastic body will brake said connection rod in reverse, which in turn bring said central axis into motion in reverse, thus stabilizing said drag wheel and buffering the force generated by the vibrations as caused by said drag wheel passing through uneven ground or indentations on the ground, hereby effectively achieving shock-proof.

Abstract: The present invention discloses a slide-cover handlebar device whose handlebar body has a slide cover to conceal the button arranged in a recession of the handlebar body, and whose handlebar body also has a torsion spring. The torsion spring has a fixing ring press-fitted with a fixing protrusion of the slide cover. When the slide cover is pulled or pushed, the torsion spring is also driven to move. When the pulling or pushing force has reached a critical point, the torsion spring generates a rotation torsion force to keep on pulling or pushing the slide cover to reveal or conceal a button. The present invention can protect the button from being imprudently pressed. The torsion spring can assist the user in opening or shutting the slide cover.

Abstract: A side-release buckle including a female portion with an extension is disclosed. The present buckle includes a male portion and the female portion. The female portion has an opening for receiving the male portion. After the male portion is attached to the female portion, the extension of the female portion can cover the whole rear part of the male portion. Thus, only an integratedly plain surface of the female portion including the extension can be seen from a front view. There can print different drawing on the plain surface to increase delicacy of the buckle. Further, the belt connected to the male portion is prevented from being worn because of the shielding protection of the plain surface.
