Description

[0001] The present invention relates to a hand operated piston pump having a multiple use possibility, that is invented and at first supplied in the market by exclusively and only me.

[0002] Prior art has to demonstrate pumps as such, the majority of which have serious dissadvantages making their use difficult, time delaying and ineffective.

[0003] Said prior art dissadvantages result because of the presence of only a single part of pipe constituting the main pump body, as well as their constructive details.

[0004] Specifically, the simple bearing no support. means pump possesses the dissadvantage of absence of support and stabilisation of any kind on the container mouth, as there usually exists a diameter difference between the container mouth and the pump part immersed into the liquid to be pumped and it is because of this that the user is faced up with the problem to either have help or hold the pump tight and steady with one hand, at the point where the pump pipe is in contact with the container mouth and carry out pumping with the other hand, with this resulting to a time delaying and tiring process.

[0005] Refering to pumps bearing a fixed support means on the liquid container mouth, has to be pointed out that their use is restricted to containers of certain height only, because as it is obvious said fixed support means limitates the pipe length to that part immersed into the container of larger diameter, with this resulting to incomplete pumping in case that said pump is used for containers of larger diameter, for the reason that access of the pump pipe in so far as the container bottom, would be impossible.

[0006] With this invention is presented a hand operated piston pump, that eliminates all dissadvantages of all known prior art pumps, as the details and characteristics constituting it, widen its use further for liquid pumping from different height and capacity containers and moreover for other uses such as cleaning of swimming pools, garden ponds and fountains, sea vessels, etc and they ensure stable, fast, easy and complete liquid pumping.

[0007] An important constructive detail of the hand operated pump of the invention is that it bears a rhomboid head for liquid storage during pumping, with this resulting to non-interrupting entirely the feeding of pumped liquid towards the outlet point with continuous reciprocating motion, as well as the possibility of air escape through the outlet points on one hand and the pumping time reduced by half as compared with the pumping time required for the same amount of liquid using a prior art pump on the other.

[0008] A further important constructive detail of the hand operated pump of the invention is that it bears a valve system constituted by two parts—a piston valve and a base flap valve—, so that in combination with the simultaneous operation of both faster, more effective and much greater liquid pumping possibility is achieved.

[0009] Moreover another constructive detail of said pump is that it bears a properly formed additional tapered pump support component on the liquid container mouth, having also the possibility of being attached and stablelised on a container mouth of any diameter dimension and said tapered component bearing a properly formed pump pipe housing, allowing the stabilisation of the hose in proper place, as well as its adjustment for increasing-decreasing the pump pipe immersed into the liquid, in order that access to any height of liquid surface is achieved, so that complete pumping is carried out.

[0010] The use of the hand operated pump of the invention can be widened to the cleaning of swimming pools, garden ponds fountains, etc, from any kind of dirt, by simply applying a special dirt retaining filter at the outlet point, whereas in another embodiment it may bear an oblong flexible pipe for liquid transfer to other containers.

[0011] The object of this invention will be fully comprehended with reference to the drawings accompanying it, where it is shown descriptively in a non-restrictive way as a whole and will all side details constituting it, where :

[0012] FIG. 1 is a face view of the hand operated piston pump, bearing a tapered componed.

[0013] FIG. 2 is a section of the hand operated piston pump.

[0014] FIG. 3 is a section of the detail of the inlet point and the valve system.

[0015] FIG. 4 is a face view of the hand operated piston pump bearing no tapered component.

[0016] FIG. 5 is a face view of the tapered component.

[0017] FIG. 6 is a section of the tapered component.

[0018] FIG. 7 is face view of the hand operated piston pump bearing a filter at the outlet point, and

[0019] FIG. 8 is a face view of the hand operated piston pump bearing an oblond flexible pipe at the outlet point.

[0020] Specifically, the hand operated piston pump is constituted by a main part with a rhomboid head (1), a pumping pipe part (2), the lower end of which bears a special base with a flap valve (12) at the liquid inlet point (13), which base (9), is properly fixed at the lower end of the pipe part (2) by means of a housing, created by an internal projection (10) and an external projection (11). The flap valve (12) having an opening-closing possibility at the liquid inlet point. A piston (4) bearing a grip (5a) on its upper external end and an escpecially constructed valve (5,6,7,8) on its lower end, movable within the pipe parts (1) and (2), said valve being constituted by a main part-plastic membrane (8), an auxiliary mounting ring (7), an upper lock valve support (5) and a lower lock valve support (6). Externally, at the pipe part (2) it bears a tapered component (14) for supporting, stablelising and mounting of said pump pipe, having external support rings (15) for supporting of the pump on containers having various mouth diameter dimensions and a guide (16) for increasing-deacreasing the pump pipe part, immersed into the liquid, as well as the pump stablesing, whereas at the outlet point (3) there is mounted an additional curve shaped pipe part. Moreover for further applications such as cleaning of swimming pools, garden ponds, fountains, sewage etc., there is attached a dirt retaining filter (17), or alternativelly for other kind of use, such as the pumping from the internal of boats or, sea vessel engines, the tranfer of liquid from one steady fixed container to another spaced apart steady fixed container, etc there is attached an oblong flexible pipe (18).

[0021] It has to be mentioned at this point that the rhomboid head of the pump, bears an opening (1a) for the insertion and operation of the piston (4), which opening (1a) has such a diameter so that there exists a little gap, allowing air escape, with this resulting to storage, additional feeding and directing of the liquid from said compartment (1) towards the outlet point (3) during continuous pumping.

[0022] Moreover the rhomboid shape of the head (1) in combination with the opening (1a) and the outlet point (3) create an open circuit, ensuring much greater and faster pumping possibility, for the reason that there exists a retaining and storage of a considerable amount of liquid within the aforesaid rhomboid compartment (1), with this resulting to the possibility of use of the pump in further applications, such as the water pumping from boats, barrels etc.

[0023] The valve system (5,6,7,8), the piston (4) and base flap valve (9,10,11,12,13), which could be characterised as a composite operation system, ensures the pumping because it is achieved as follows:

[0024] During the first pulling of the piston (4) action in an upwards direction, the air from the point (1a and 3) of the rhomboid head (1) is removed, with this resulting to simultaneous liquid inlet through the flap valve (12) of the base. With continuing the reciprocating piston (4) movement, pumping is thereon achieved mechanically by means of the piston valve (5,6,7,8 ), transfering the liquid towards the outlet point and storing some amount of liquid into said rhomboid compartment (1) at the same time, which liquid is finally discharged from the outlet mouth (3).

[0025] It must be mentioned at this point that the hand operated piston pump of the invention is made of plastic, mental or any other suitable material available, for eadible and drinkable liquids or for industrial and any other use liquids.

[0026] Furthermore, it has to particularly be emphasized that this description is based upon certain indicative and not at all limitative embodiments of the invention, without making reference to exact total or partial dimensions—heights, diameters etc.—which may be altered according to requirements of use each time.

[0027] Additionally, it has to particularly be emphasized that the shape of the tapered component for supporting, stablelising and mounting of the pump pipe onto the container mouth, as well as the dimensions of said tapered component may be altered, in order that there will the possibility of the pump mounting and pumping extensively, from any container, having any mouth diameter dimension and any other than circular shape of mouth.

[0028] Conclusively, any modification of the object of the invention, as regards its total or partial dimensions as well as the dimensions of its additional components, of its components' shape or of its material of manufacture by any party will intend to copying and unfair competition, causing punishment as provided by law.
