Suction cup device

A sucker being diversified and/or improved and/or more endurable and/or more effective and/or convenient and/or multi-functional and/or more efficient is provided. The sucker includes a downwardly concave sucking body to be pressed against an attaching surface to vacuumize the room defined therebetween, a downwardly concave resilient member superimposed above the sucking body and having a periphery and a plurality of grooves, and a connector connecting together the sucking body and the resilient member in the manner that after the sucking body has been pressed against the attaching surface, the resilient member will tend to urge the sucking body away from the attaching surface which will in turn result in that the sucking body is more securely attached to the attaching surface.

BACKGROUND OF THE INVENTION 
The present invention relates to a Suction Cup Device, and more 
particularly to one for daily use. 
It is not seldom found that the conventional sucker fails to normally 
function due to factors including the deformation or the aging or the 
hardening of the used material and the change of the ambient temperature, 
moisture or atmospheric pressure, any of which probably leads to the fact 
that the air molecules run into the room between the sucker and the flat 
surface attaching thereto the sucker which explains why the sucker fails 
to desiredly work. To the Applicant's knowledge, the human being stands 
helpless before the above problem till now. It is therefore tried by the 
Applicant to deal with the above problem encountered by the prior art. 
SUMMARY OF THE INVENTION 
It is therefore an object of the present invention to provide a 
functionally and/or apparently diversified sucker. 
It is further an object of the present invention to provide a more 
effective and/or convenient sucker. It is additional an object of the 
present invention to provide a longstandingly functioning sucker. 
According to the present invention, a sucker includes a sucking body having 
a downwardly concave surface to be downwardly pressed against an attaching 
surface to vacuumize the room therebetween so that the sucking body can be 
attached to the attaching surface, a downwardly concave resilient member 
superimposed above the sucking body and having a periphery and a plurality 
of grooves beginning from the periphery, and a connector connecting 
together the sucking body and the resilient member in the manner that 
after the sucking body has been pressed against the attaching surface, the 
resilient member will tend to urge the sucking body away from the 
attaching surface which will in turn result in that the sucking body is 
more effectively attached to the attaching surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring now to FIG. 1-FIG. 1-4, there is shown a sucker according to the 
present invention which includes a sucking body B having a downwardly 
concave surface B2, a connector C integrally formed to sucking body B and 
having an enlarged upper portion C1, and a resilient member A which is 
superimposed above sucking body B and includes a downwardly concave 
surface A1, a periphery A2 and a plurality of grooves A3 beginning from 
periphery A2 and oriented toward a central opening A4 capable of 
compelledly passing therethrough upper portion C1 to enable resilient 
member A to be retained by upper portion C1. In use, the present sucker is 
pressed against a flat attaching surface G as shown in FIG. 1-3 to 
discharge the air out of the room E defined between sucking body B and 
flat surface G to thus attach sucking body B to attaching surface G. After 
released, resilient member A tends to urge sucking body B away from 
attaching surface G as shown in FIG. 1-4 which forms a compulsive vacuum 
state in room E so that sucking body B is more effectively attached to 
attaching surface G since the air in room E gets in no way saturated no 
matter what the environmental temperature or atmospheric pressure may 
change. 
As shown in FIG. 1-5, resilient member A can be smaller than sucking body B 
having a peripheral portion B4 in area so that periphery A2 can help urge 
peripheral portion B4 against attaching surface G which is advantageous in 
effectively preventing the environmental air from running into the room E 
should sucking body B have a deformation due to the change of the 
environmental temperature or moisture. 
As shown in FIG. 1-6, since member A is resilient and has grooves A3 so 
that periphery A2 is sufficiently flexible in different positions thereof, 
resilient member A can help sucking body B attach itself to an irregular 
attaching surface G1. Certainly, the number of grooves A3 can be desiredly 
varied to cope with the need of a particular situation. 
As shown in FIGS. 2 & 3, a resilient member A according to the present 
invention can alternatively have curvy grooves S or grooves R each of 
which has an elliptical portion and a straight portion. 
As shown in FIG. 4, since periphery A2 can help peripheral portion B4 to 
attach itself to the attaching surface, a sucker according to the present 
invention can be generally rectangular. Connector C can have a transverse 
through hole C2 through which a stopper M can pass to stop thereunder 
resilient member A. As shown in FIG. 5, the present sucker can be 
generally elliptical and connector C can have the upper portion thereof 
engage thereunder a C-shaped stopper N stopping thereunder resilient 
member A. 
As shown in FIGS. 6 & 6-1, central opening A4 of member A can further 
include extensions A5 to be gear-shaped so that compelledly passing upper 
portion C1 of connector C through central opening A4 is made easier. 
Certainly, the toothed portions A6 of member A can be tapered to further 
ease the engagement between connector C and member A. In order that the 
present sucker can easily be detached from the attaching surface, sucking 
body B is provided with an extension B5 capable of being upwardly pulled 
to allow the air to run into the room between sucking body B and the 
attaching surface. 
As shown in FIG. 7, connector C having a transverse through hole C111 can 
be independent of sucking body B but partly implanted therein during 
manufacturing sucking body B so that connector C can be made of a rigider 
material in order that a strongly resilient member A can be introduced to 
the present sucker since sucking body B integrally forming thereto 
connector C as shown in the previous examples is made of a relatively soft 
material so that the soft connector C tends to be deformed or damaged to 
fail to desiredly function if a strongly resilient member A is used. As 
shown in FIGS. 7-1, 7-2 & 7-3, the independent connector C can have an 
upper portion having an inner thread, an outer thread or a 90 
degree-turnedly H-shaped crosssection so that connector C can easily be 
engaged to an article desired to be or capable of being attached to an 
attaching surface by a sucker. 
As shown in FIGS. 8 & 8-1, connector C' can alternatively be integrally 
formed to resilient member A implanted into sucking body B. Certainly, 
connector C' in this embodiment can also have an upper portion of 
different structure as described in the foregoing embodiment. 
As shown in FIG. 9, a sheet article or a paper P can be securely clamped 
between resilient member A and sucking body B attached to an attaching 
surface so that an adhesive or a tack or the like can be dispensed with in 
order that the attaching surface always maintains its cleanliness and 
smoothness. 
As shown in FIG. 10, a resilient member A according to the present 
invention can attach thereto a hooking member H so that the attaching 
surface for the present sucker/hook will not be contaminated or damaged. 
In sum, the advantages achieved by the present sucker can be summarized as 
follows: 
1) The present sucker not only can be effectively attached to the attaching 
surface but also can be made to be detachable from the attaching surface 
in a more easier manner. 
2) Although subjected to severe atmospheric changes, the present sucker can 
still longstandingly work effectively. 
3) Although inevitably subjected to the aging or the hardening of the used 
material of sucking body B, the present sucker can still longstandingly 
function normally. 
4) The present sucker can successfully function on an irregular attaching 
surface. 
5) The present sucker can structurally be diversified. 
6) The present sucker can apparently be diversified. 
7) The present sucker can functionally be diversified. 
While the present invention has been described in connection with what is 
presently considered to be the most practical and preferred embodiments, 
it is to be understood that the invention is not to be limited to the 
disclosed embodiments but on the contrary, is intended to cover various 
modifications and equivalent arrangements included within the spirit and 
scope of the appended claims which scope is to be accorded the broadest 
interpretation so as to encompass all suck modifications and equivalent 
structures reasonably deemed by those skilled in the art.
