Abstract: A packaging pad includes a supporting portion for supporting a piece of goods, and an enclosing portion; the supporting portion includes several different-sized geometric protrusions each having an air room therein; the air rooms don't communicate with each other; the enclosing portion encloses the supporting portion for enclosing a circumferential side of one end of a piece of goods supported on the supporting portion; the enclosing portion includes several different-sized geometric protrusions each having an air room therein; the air rooms don't communicate with each other; the protrusions of the enclosing portion are taller than those of the supporting portion; therefore, when a piece of goods is positioned on the supporting portion, one end of the piece of goods and a circumferential side of the end of the piece of goods will be protected from damage in transportation with the protrusions serving as buffers.

Abstract: A shell of a metallic cabinet is made by means of folding two ends of a metal plate form fitting portions at the two ends, bending the metal plate and making the fitting portions engage each other to change the metal plate into a semi-finished shell, pressing the fitting portions against each other such that the fitting portions become flat to closely touch each other, and bending upper and lower ends of the semi-finished shell inwards to form inward annular fitting protrusions thereon, shaping the semi-finished shell by means of exerting outward force on inner portions of the semi-finished shell, and punching a front side of the semi-finished shell to form an opening; a cover and a base are respectively secured to the upper and the lower ends with bumps, which are formed near to edges of the cover and the base, engaging the fitting protrusions of the shell.

Abstract: A serving tray includes a holding portion, and handles at two sides of the holding portion; the holding portion has trenches formed on an upper side, recesses formed on a bottom, a through hole, upper flow passages formed on the upper side, and lower flow passages formed on the bottom; the handles have second recesses formed thereon. Slip-prevention rubber sheets are attached to the trenches and the recesses by means of injecting melted rubber into a mold used for making the holding portion and the handles via the through hole for the melted rubber to be applied over the trenches, and the recesses via the upper and the lower flow passages.

Abstract: A seat of a chair is provided with a plastic main body, a metallic upper cover joined to upper and annular sides of the main body, and a metallic lower cover securely disposed over the bottom of the main body. The metallic covers increase the strength of the seat. The bottom of the plastic main body is formed with vertical connecting tubes, which are tightly fitted around corresponding sleeves secured to upper ends of metallic legs of the chair. The tubes have inner annular protrusions, which are engaged with annular grooves formed on outer sides of the sleeves; and, the seat matches the metallic legs to a greater degree because the outer side of the seat is made of metal.

Abstract: A protective cover of a grille-shaped article support includes a flat portion for holding articles on, and a surrounding wall joined to edges of the flat portion. Clipping elements are provided on bottom side of the flat portion, and hooking elements are provided on inner side of the wall. The cover is firmly fitted over the article support with the clipping elements clipping onto corresponding metal bars of the article support, and with the hooking elements hooking onto edges of the article support so that articles can be stably held on the article support.

Abstract: A table includes an upper flat board having the edge folded to join the edge of a lower shaped board. The lower shaped board has lower side strengthening ribs radially extending from a central connecting part. An inner rod is connected to the central connecting part from an upper threaded portion, and connected to a base member from a lower threaded portion. An outer tube is placed around the inner rod with a top abutting the central connecting part. A plastic sleeve is passed into a lower end of the outer tube with the central hole encircling the inner rod, and has a lower end flange interposed between the bottom of the outer tube and the upper side of the base member. Thus, the boards are held at an elevated position by both the inner rod and the outer tube.

Abstract: An oil hydraulic device for a lid of a garbage can includes a pressure valve, a pushing valve, a hydraulic pipe, a reducing valve and a pedal. The pressure valve is connected to a container of the garbage can, and has a piston capable of moving forwards on the pedal's downward movement. The hydraulic pipe is connected to the pressure valve from a lower end, and the pushing valve from an upper end. The pushing valve is secured to an upper part of the container, and has a piston rod movable upwards to pivot a movable member on said garbage can to open said lid connected to said movable member. The reducing valve is connected to an intermediate portion of said pipe for absorbing a part of pressure of oil in said pipe on said pedal's downward movement.

Abstract: A garbage cam with a push-open cap connected to a pedal interactive device includes a can body, a push-open cap pivotally connected to an inner side of an opening of a can cap, a torque spring to automatically push the push-open cap to move back to close the opening, and a pedal interactive device to pull open the push-open cap. The pedal interactive device consists of a pedal provided at a lower end of the can body, a rope having a first end fixed with the push-open cap and a second end wound around a rope wheel connected to a gear engaging a vertical rack positioned between an upper and a lower rib plates units. The rack is pushed up to rotate the gear and the rope wheel to wind the rope when a user steps down the pedal so that the push-open cap is pulled to open, and the push-open cap automatically moves to close up the opening when the user releases the pedal.

Abstract: A trash can with a cap opened with a step includes an outer trash can, an inner trash can, a cap closing on the outer trash can, a moving mechanism and a step. The step is positioned outside of the outer trash can with a first end of a movable rod of the moving mechanism located just under the step. So, when the step is pressed down with a foot of a user, the movable rod moves up a connecting rod vertically to push the cap to swing up open, as the cap is pivotally connected with a projection fixed on a rear end of the cap. Further, a decorative cap is pivotally connected with the projection, hiding an upper end of the connecting rod protruding out of the outer trash can so as to beautify the whole shape of the trash can.

Abstract: A block includes first and second through holes extending from an upper side thereof through a lower side thereof. A necking passage section is defined between and thus communicates with the first and second through holes. A lower end of the first through hole coincides with the lower end of the second through hole. The first through hole has a central axis which is at an angle to that of the second through hole. The first through hole has a diameter the same as that of a rod to which the block is mounted. The upper end of the second through hole has a diameter greater than that of the rod and tapers to the lower end of the second through hole which coincides with the lower end of the first through hole. The necking passage section is resilient to allow the rod to be forcibly moved between the first and second through holes. An antislip member is provided to an inner periphery of the first through hole. The rod is retained in position when it is received in the first through hole.
