An umbrella includes a shank, a fixed ring mounted on the shank, a movable ring movably mounted on the shank, a plurality of ribs each pivotally and detachably connected with the fixed ring, and a plurality of spreaders each pivotally and detachably connected with the movable ring. Thus, each of the spreaders and the ribs can be removed from the movable ring and the fixed ring respectively for replacement or maintenance, thereby enhancing the lifetime of the umbrella.

A furniture automatic resetting type press and rebound mechanism comprises a furniture movable part, a furniture immovable part, connecting elements and a fixed support. The furniture movable part is movably arranged on the furniture immovable part in an opening-closing mode, a press and rebound device, a stretchable resetting device and at least two rotating wheels are arranged on the fixed support, the press and rebound device at least comprises pushing and moving elements, and the stretchable resetting device at least comprises stretchable elements and first elastic elements which are mutually matched in an elastic mode; the pushing and moving elements and the stretchable elements are slidably arranged on the fixed support, the at least two rotating wheels are arranged in a relatively independent mode and rotatably arranged on the fixed support, the at least two rotating wheels are mutually matched in a linkage mode when rotating to a certain position, one of the two rotating wheels is in driving connection with the stretchable elements, and the other one of the two rotating wheels is in driving connection with the pushing and moving elements; and swing elements are arranged on the pushing and moving elements, heart-shaped sliding chutes are formed in the fixed support, the swing elements are arranged on the pushing and moving elements in a swinging mode, and one ends of the swing elements sequentially slide along tracks of the heart-shaped sliding chutes towards one direction when the pushing and moving elements slide.

Rolling basket structure facilitating movement of the rolling device to and from a field-working position includes arm structure pivotally connected to the aft end of tine support members fixed to the rear of the implement frame. Hydraulic cylinders connected between the support members and the arm structure provides quick on-the-go disengagement of the rolling basket with the ground, for example, when wet or sticky ground conditions or the like are encountered. A cylinder lost motion connection facilitates movement of the baskets over ground irregularities and obstacles without operation of the cylinders.

The invention relates to a semi-flexible structure permeable street and a pavement method thereof. The structure of the street comprises a fully-permeable multilayer pavement structure roadbed or a drainage multilayer pavement structure roadbed, a permeable grid plate cushion paved on the roadbed, and a street surface layer paved on the permeable grid plate cushion. By paving the permeable cushion formed by the linked pavement of permeable grid plates on the fully-permeable multilayer pavement structure roadbed or the drainage multilayer pavement structure roadbed, the semi-flexible structure permeable street which is constructed on condition that the permeable grid plate structure is reasonably designed, the manufacturing material of the permeable grid plate cushion is reasonably selected and the unit structure of the street surface layer is reasonably designed has the advantages of good permeability and strong water storage capability, and the surface layer and the permeable grid plate cushion of the street have a good combination degree and are easy to disassemble, replace and maintain.

A clothes hanging stand device mainly has a pair of vertical stand oppositely facing with each other, several frames connecting the pair of vertical stand and a shelf stand set up in the hanging space formed by the pair of vertical stand. The expansion or contraction of the shelf stand can provide an enlarged two-level hanging space, or a full height hanging space for apparel. Furthermore, the hanging space can be further expanded to the outside of the pair of the vertical stand by the extending of an extending rod of the horizontal oriented frame. Quick assembling and disassembling among the components can be achieved. Additionally, the whole device after collapse takes little volume space for easy store-up.

A wine glass constructed from molded plastic includes an upper body defining an upwardly narrowed flume for concentrating the wine bouquet, in combination with a contoured lower base defining an annular moat surrounding a central punt for enhanced visual inspection of the wine. In addition, the upper body further includes a notched indent at an outboard side thereof forming a shelf for facilitated fingertip grasping and manipulation of the assembled glass. In one form, the upper body and lower base of the wine glass are provided as separate modules adapted for assembly to form the wine glass, and disassembly for respective compact stacking. In another form, the wine glass has a one-piece construction adapted for compact stacking by nested reception of the upwardly narrowed flume partially into the underside of the lower base of an overlying glass in the stack.
