Definitions

  • the present invention relates generally to a refuse collection device for collecting refuse in a more sanitary manner.
  • the principal object of the present invention is to provide a refuse collection device which is easier to manufacture and operate so as to reduce the manufacture cost and to facilitate the operation thereof by the general consumers.
  • a refuse collection device comprising an elongated tubular assembly comprising an inner tube, an intermediate tube and an outer tube telescoping each other and a bag mount supporting thereon a refuse collection bag attached to the lower end of the tubular assembly and closable by means of a pivoting cover.
  • a manual control is provided, comprising a first grip fixed to the outer tube and a second grip fixed to the intermediate tube so as to allow the first grip and the outer tube to be movable relative to the second grip and the intermediate tube between an upper open position and a lower closed position.
  • the cover is coupled to the outer tube so as to be driven thereby between the open position and the closed position.
  • Spherical members are received within openings formed on the intermediate tube and spring-biased to selectively engage corresponding recesses formed on the outer tube so as to secure the outer tube in the open position.
  • the inner tube is also movable and spring-biased relative to the intermediate tube to expand and thus securely hold the collection bag.
  • a releasing mechanism is provided to move the inner tube relative to the intermediate tube against the biasing spring for releasing the bag. The releasing mechanism also functions to release the outer tube from the open position.
  • the refuse collection device of the present invention comprises an elongated rod or tubular portion which in general use is substantially upright with an axis thereof extending substantially vertically, having a lower end to which a flexible refuse collection container 6 is detachably mounted and openably closed by means of a cover 53 and an upper end to which a control 4 is mounted to open the cover 53 for collecting refuse (not shown) into the collection container 6.
  • the control 4 is designed to be handled and operable with one single hand of a user and will be further described.
  • the elongated rod portion of the refuse collection device comprises an outer tube 1, an intermediate tube 2 and an inner tube 3 telescoping each other with the inner tube 3 received inside the intermediate tube 2 and the outer tube 1 fit over the intermediate tube 2, as shown in Fig. 3.
  • Each of the tubes 1, 2 and 3 has an upper end and an opposite lower end.
  • the control 4 is mounted to the upper end of the intermediate tube 2.
  • the lower end of the inner tube 3 extends outside the intermediate tube 2 with a bag mount 5 fixed thereto for supporting the collection container 6.
  • An externally-threaded plug 56 is provided to threadingly engage the inner threading 33 of the inner tube 3 through the opening 51 of the bag mount 5 to support and retain a helical spring 54 within the lower end of the inner tube 3.
  • the inner tube 3 is provided with a first pair of slots 32 which are elongated in the axial direction and diametrically aligned with each other to movably receive therein a pivot pin 535 extending through both slots 32.
  • the elongated slots 32 of the inner tube 3 has a predetermined axial length which will be further discussed.
  • the slots 32 are axially spaced from the lower end of the inner tube 3 to define a distance between the pin 535 and the plug 56 for accommodating therein the spring 54.
  • the spring 54 is in general compressed to bias the plug 56 that is fixed in the lower end of the inner tube 3 away from the pin 535 so as to locate the pivot pin 535 at an axial upper end of the elongated slots 32 of the inner tube 3, as shown in Figs. 3 and 4.
  • the intermediate tube 2 is provided at a lower portion thereof that extending outside the outer tube 1 with two diametrically opposite holes 23 corresponding to the slots 32 of the inner tube 3 to allow the pivot pin 535 to extend therethrough to serve as a pivot for the cover 53.
  • the cover 53 comprises a semi-circular plate, substantially corresponding to the semi-circular frame of the bag mount 5 with an extension substantially parallel with the elongated rod portion in the axial direction.
  • the semi-circular plate has two lugs 530 extending therefrom and spaced from each other in such a way to receive the elongated rod portion, particularly the lower end of the intermediate tube 2, therebetween.
  • Each of the lugs 530 is provided with a hole 531 aligned with each other and corresponding to the holes 23 of the intermediate tube 2 to receive the pivot pin 535 therethrough.
  • cover 53 to be rotatable about the pivot pin 535 and thus making the semicircular plate portion of the cover 53 movable relative to the bag mount 5 between an open position and a closed position for opening/closing the refuse passage defined between the upper section and lower section of the bag mount 5.
  • Biasing means 534 is provided between the elongated rod portion and the cover 53 to bias the cover 53 to close the refuse passage defined by the bag mount 5.
  • the refuse passage defined by the bag mount 5 is a normally-closed design. Namely, it is normally closed by the cover 53 under the biasing force of the biasing means 534 and will only be opened by manually actuating the control means 4 to move the cover 53 against the biasing means 534. This prevents the refuse collected in the collection container 6 that is mounted to the bag mount 5 from accidentally falling off the collection container 6 to cause a second time contamination. The actuation of the control means 4 for opening the cover 6 will be further discussed hereinafter.
  • the biasing means 534 comprises a torsional spring, having a U-shaped configuration fit outside the two spaced lugs 530 of the cover 5.
  • the U shape has two side limbs, each having a plurality of turns of the torsional spring formed thereon to define a bore 5341 loosely fit over the pivot pin 535 to be held therein.
  • the limbs of the U shape also have a bent end 5342 to be received and held within corresponding apertures 222 formed on a sideways tab 22 fixed to the intermediate tube 2.
  • a connecting link 533 is provided to connect between the cover 53 and the outer tube 1, see Fig. 3. This is accomplished by providing hook-like members 12 and 532 on both the outer tube 1 and the cover 53 and forming hangers on both ends of the connecting link 533 to engage the hook-like members on the outer tube 1 and the cover 53.
  • the control means 4 comprises a cylinder 47 which is sized to be received and fixed within an upper end of the intermediate tube 2 by any suitable means, such as press fitting or welding or simply a pin 470 (see Figs. 2 and 3) extending through both the intermediate tube 2 and the cylinder 47.
  • the cylinder 47 comprises a central bore which is provided with inner threading 471.
  • the threading 471 is formed so as not to interfere with the pin 470 that secures the cylinder 47 to the intermediate tube 2, see Fig. 3.
  • the intermediate tube 2 is arranged inside the outer tube 1 so that the upper end of the intermediate tube 2 is completely located within the outer tube 1.
  • a cylindrical sleeve 46 having an outer diameter substantially corresponding to that of the intermediate tube 2, is fit into the upper end of the outer tube 1 with a portion thereof located outside the outer tube 1 and secured to the outer tube 1 by means of for example a rivet 460 so as to serve as an axial extension of the outer tube 1.
  • the sleeve 46 has a central bore defining a substantially smooth inner cylindrical surface, into which a hollow shaft 41 is movably fit.
  • the hollow shaft 41 has threading 410 and 411 provided at both upper and lower ends thereof.
  • the user may now release the outer tube 1 by depressing the button 424 against the compression spring 43.
  • This moves the shank 42 relative to the spherical members 413 within the openings 412 of the hollow shaft 41 to such a position where the first recesses 421 of the shank 41 are substantially aligned with the openings 412.
  • the spherical members 413 are forced into the openings 412 of the hollow tube 41 with a portion thereof received in the first recesses 421 and the outer tube 1 is allowed to move downward by being acted upon by the spring force of the torsional spring 534 and the own weight thereof.
  • Such a downward movement of the outer tube 1 and the torsional spring 534 accelerates the rotation of the cover 53 toward the closed position as shown in Fig. 3.
  • the cover 53 strikes and scoops the refuse into the primary bag 60 via the refuse passage defined by the bag mount 5.
  • the slots 31 and 21 of the inner tube 3 and intermediate tube 2 are dimensioned and positioned so that the movement of the outer tube 1 from the closed position in Fig. 3 to the open position in Fig. 4 is not interfered with by the slots 21 and 31 and when the outer tube 1 is at the closed position, the pin 13 that is carried by the outer tube 1 is substantially coincident with the upper end of the slots 31 of the inner tube 3, see Fig. 4.
  • the refuse collection container 6 may be detached from the bag mount 5 without the user's hand(s) directly touching the collection container 6. This is done by horizontally holding the refuse collection device with the cover 53 facing upward and pulling the movable grip 45 toward the fixed grip 44. The operation brings the first step 461 of the sleeve 46 to the position where it aligns with the openings 412 of the hollow shaft 41 so that the spherical members 413 enter the first step 461 of the two-stepped groove of the sleeve 46 and engage the first step 461 and the arc edge thereof. This is identical to the operation of opening the cover 53.
  • the movement of the sleeve 46 to have the first step 461 engaged by the spherical members 413 that are held within the openings 412 of the hollow shaft 41 may be unlimitedly repeated for arbitrarily opening the cover 53 to perform a number of times of scooping refuse into the container 6 and also in the final, detachment operation of the refuse collection container from the bag mount 5.
  • the present invention provides a simple and ready-to-operate mechanism for a user to repeatedly open and close the cover in collecting refuse which also provides a similar operation in disposing the refuse so collected by detaching the collection container from the bag mount 5.
  • the spring 54 is compressed and the distance between the upper peg 221 on the intermediate tube 2 and the lower section of the bag mount 5 (or more precisely the lower pegs 55) is reduced. This loosens the primary bag 60 from the lower pegs 55 and the upper peg 221.
  • the user may simply shake the refuse collection device to detach the primary bag 60 from the bag mount 5. Thereafter, by rotating the refuse collection device to have the cover 53 facing downward, the weight of both the refuse collected and the primary bag 60 drives the second bag 61 off the cover 53 with the connection therebetween provided by the extension strip 603 of the primary bag 60.
  • the refuse collected in the primary bag 60 and the collection container 6 are both disposed into any suitable processing device or facility without the user's hand directly touching the probably contaminated collection container 6.
