A handrail means for a bed frame includes a handrail frame, a shield, a handrail fixing frame, and a swinging assembly. When the swinging assembly acts, the shield does not act yet so as to avoid from interfering with the swinging assembly. When the swinging assembly is oriented horizontally, the shield can be folded toward the inside of the handrail frame. When the swinging assembly achieves a predetermined point, the shield has completed its action. Therefore, during the action, the shield avoids the handrail means from contacting the ground, thereby smoothing the folding of the handrail means of the bed frame.

One end of the second transmission arm is slidably connected with the second fixing frame, the other end of the second transmission arm is rotatably connected with the spindle, the two ends of the second rotating arm are rotatably connected with the second fixing frame and the spindle respectively, and the second supporting plate is erected between the second fixing frame and the spindle and fixedly connected with the second rotating arm. The bending mechanism of the folding device can strongly support the flexible display screen, so that the reliability of the flexible display screen is high, and the service life of the flexible display screen is long.

A folding completion body of a head-protecting airbag includes a compressed portion which is compressed to have a small sectional shape in an axis orthogonal direction in the folding completion body is provided in at least one end in a front and rear direction, wherein: the compressed portion is formed in such a manner that a thin-plate folded portion is disposed by folding back an end periphery in the front and rear direction to be directed to a center in the front and rear direction in a state where the head-protecting airbag is flatly deployed, and a folded-up portion in which the lower periphery is brought close to the upper periphery is provided; and the thin-plate folded portion is configured such that a tip extending from a crease is disposed to be positioned on an end side of the gas guidance path in the front and rear direction.

Disclosed herein is a folding recliner of a seat for vehicles which is able to execute both seat folding and reclining motions using only a single lever. The folding recliner of the present invention includes a lever unit, which has a lever pin and a lever, so that, when the lever is rotated in a predetermined direction, the lever unit is rotated around a reclining shaft so that the seat back enters an unlocked state. The folding recliner further includes a first link, which has a contact part on a lower end thereof, and a second link, which is rotated around a rotating shaft, coupled to the second link, by movement of the first link. The folding recliner further includes a spring, which is coupled between the second link and a frame unit, and a cam, which is rotated around the rotating shaft and has a locking protrusion. The folding recliner further includes a latch which is rotated around a folding shaft and has a curved edge part, so that the curved edge part contacts an upper end of the cam so that the seat back maintains an unfolded locked state thereof, and a locking notch formed at a predetermined position in the outer edge of the latch so that the locking protrusion of the cam is locked to the locking notch so that the seat back maintains a folded locked state thereof.

A bed frame connector is connectable between upper and lower lateral bars of a foldable bed frame. The bed frame connector includes an L-shaped plate structure that includes a straight body and an angled section extending outward from an end of the straight body. A pivot hole is formed in an end of the straight body and the angled section. The straight body includes two support blocks that project from an edge thereof intersecting the angled section. The two support blocks are positionable between and respectively abutting the upper and lower lateral bars. The present invention has a simple structure and a reduced manufacturing cost and provides secure support and smooth foldability.

A half spread folding door is comprised of plural door leaves; door frames supporting each door leaf in both side ends thereof; a hinge means for connecting successively each door leaf with adjacent door leaf along its width direction, a pair of hinge means are lengthwise each mounted in both side ends of the door leaf and plural hinge means are lengthwise mounted in the middle of the door leaf, allowing each door leaf to be rotated around a hinge shaft correlatively, and for folding each door leaf toward alternative dead end of the door leaves sequentially; and a spread confining means for limiting relative rotation angles of every door leaves interconnected by the hinge means and a spread range of each door leaf in an angle of 30° to 60° to configure as the form of zigzag when the door leaves are spread. Each door leaf has a form of zigzag when closed, a thinner thickness door than a conventional flat type folding door can be configured using the same property material, which attains the very lighter but highly rigid door. The door can be easily opened / closed and the door leaves can be smoothly folded during its opening operation, adapting to use an opening of large structure or a foldable roof such as large depot and an airshed, etc.

In a mechanism and method for bonding two paper sheets on an interfolding machine, pre-compressing mechanisms are provided on each of two folding rollers to produce compress-to-bond areas on overlapped portions of two thick or air-impermeable paper sheets transferred to the two folding rollers, so that all plies of the two paper sheets at the compress-to-bond areas are compressed to bond together. Thereby, when the interfolding machine operates at a high speed, a plurality of the locally compressed and bonded paper sheets may still be smoothly folded to form a stack of interfolded paper sheets, such as a tissue paper stack or a paper towel stack.

A sanitary product for use by women for the absorption of menstrual fluid, having a plug and a pad joined by a sheath. The plug is substantially cylindrical so that is fits comfortably in a vaginal cavity. The pad remains outside the vaginal cavity, but has an absorbent layer on an inward side proximal to the plug and a liquid impermeable layer on an outward side. In use, a wearer can insert a finger into the sheath from the outward side of the pad to assist with insertion of the plug into the vaginal cavity. A string is provided that extends inside the sheath from the outward end of the plug to aid removal of the product. A line of weakness extends along the major axis of the pad, about which the pad is disposed to fold in use.

The invention relates to a foldable framework structure for a baby-car, comprising an upper framework and a lower framework, wherein the upper framework is connected with the lower framework through a joint group so that the upper framework can control the joint and can be folded or unfolded and be fixed with respect to the lower framework. The lower framework is provided with a folding group to actuate the folding and the positioning as well as the unfolding of the lower framework, so that when to fold the framework structure a handler can separately fold the upper framework and the lower framework without causing injury to the baby. The invention is simple in structure, convenient and safe to use.
