Cover set

Description

BACKGROUND OF INVENTION

1. FIELD OF INVENTION

[0001] The invention relates to a cover set according to the preamble of claim 1. EP-A-1361176 discloses such a coverset.

2. RELATED PRIOR ART

[0002] Referring to Fig. 11, a conventional garbage-containing apparatus 90 is shown to include a bin 92, a cover 91 pivotally connected to the bin 92 and two elastic elements 93 for lifting the cover 91 from the bin 92. Near the end of the lifting, the cover 91 however hits the bin 92 fiercely and makes loud noise. The hit is often strong so that the entire garbage-containing apparatus rattles and makes more noise. Such noise is annoying.

[0003] To obviate this problem EP-A-1 361 176 suggests to use a buffer requiring damping oil to buffer the cover near the end of the lifting.

SUMMARY OF INVENTION

[0004] According to the present invention, a cover set according to claim 1 is provided.

[0005] The object of the present invention is to provide an alternative buffer which is simpler and cleaner.

[0006] Other advantages and features of the present invention will become apparent from the following description referring to the drawings.

DETAILED DESCRIPTION OF EMBODIMENTS

[0008] Referring to Fig. 1, there is shown a garbage-containing apparatus including a bin 1 and a cover set 2 according to a first embodiment of the present invention. The cover set 2 includes a ring 10 mounted on the bin 1, a cover 20 pivotally connected to the ring 10, a lifting device 30 for lifting the cover 20 from the ring 10, two buffers 40 for buffering the cover 20 near the end of the lifting and two shields 50 for shielding the buffers 40.

[0009] Referring to Fig. 2, the ring 10 includes a platform 11 formed on an internal side of the ring 10 and located lower than an upper face of the ring 10, four ears 12 formed on the platform 11 and two plates 14 projected from the internal side of the ring 10 and located lower than the platform 11. Each of the ears 12 is formed with a boss 13. Each of the plates 14 defines a screw hole 141 and two apertures 142.

[0010] The cover 20 is formed with four ears 21 for pivotal connection to the ears 12 and an extensive portion 23 for contact with the buffers 40. Each of the ears 21 defines an aperture 22 for receiving a related one of the bosses 13. Hence, the cover 20 is pivotally connected to the ring 10.

[0011] The lifting device 30 includes two torque springs 33. Each of the torque springs 33 includes two looped portions each arranged around a related one of the bosses 13. Therefore, the lifting device 30 can lift the cover 20 from the ring 10.

[0012] Each of the buffers 40 includes a bent portion 41 mounted on a related one of the plates 14 and a curved portion 42 for contact with the extensive portion 23 of the cover 20. A slot 43 is defined in the curved portion 42 of each of the buffers 40 so that the flexibility of the latter is improved.

[0013] A threaded bolt 60 is driven in the screw hole 141 of each of the plates 14 through an aperture defined in the bent portion 41 of a related one of the buffers 40. Thus, the buffers 40 are secured to the plates 14.

[0014] Each of the shields 50 includes two hooks 51 each inserted in a related one of the apertures 142 of a related one of the plates 14. Hence, the shields 50 are secured to the plates 14. The shields 50 shield the buffers 40 from a side while the ring 10 shields the buffers 40 from another side.

[0015] Referring to Fig. 3, the cover 20 is lifted from the ring 10. The pivoting of the cover 20 gets faster and faster.

[0016] Referring to Figs. 4 and 5, near the end of the lifting, the pivoting of the cover 20 reaches its top speed, the extensive portion 23 of the cover 20 begins to contact the curved portions 42 of the buffers 40.

[0017] Referring to Figs. 6 and 7, the extensive portion 23 of the cover 20 pushes the curved portions 42 of the buffers 40. The speed of the pivoting of the cover 20 is reduced. Therefore, the cover 20 is buffered by the buffers 40. The cover 20 does not hit the ring 10 and does not make any noise. The lifting of the cover set is steady and quiet.

[0018] Referring to Fig. 8, there is shown a cover set according to a second embodiment of the present invention. The second embodiment is like the first embodiment except including only one buffer 40 and only one shield 50.

[0019] Referring to Figs. 9 and 10, there is shown a cover set according to a third embodiment of the present invention. The third embodiment is like the first embodiment except including a lifting device 30' instead of the lifting device 30. The lifting device 30' includes two units each including a first cap 31' connected to the ring 10, a second cap 32' connected to the cover and a helical spring 33' with an end connected to the first cap 31' and another end connected to the second cap 32'. In each of the units, the spring 33 is substantially not loaded when the cover 20 is lifted from the ring 10 and loaded as the cover 20 is lowered onto the ring 10. Thus, the lifting device 30' is used to lift the cover 20 from the ring 10.

[0020] The present invention has been described through the illustration of the embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention as defined in the claims.
