WO2002072277A1 - Pump which can be actuated by a hand lever - Google Patents

Abstract

The invention relates to a pump (4) which can be actuated by a hand lever, is used to spray liquids (3), and can be especially placed on bottles (1) or the like. Said pump comprises a piston (13) which can be linearly displaced in a chamber (17) on the side of the housing, against the force of a compression spring, and which is used to spray the liquid (3) out of a mouthpiece nozzle (24). The piston (13) is coupled to the pivotably positioned hand lever (6) by means of a connecting tractional member (G) in such a way that the pivoting movement of the hand lever (6) pulls the piston (13) in the direction of the liquid (3) moving towards the mouthpiece nozzle (24). The connecting tractional member (G) extends from the rear side (49) of the piston (13), parallel to the travel of the piston and in the direction of the mouthpiece nozzle (24). A section (48) is provided on the rear side (49) of the piston (13), as a carrier for the same (13), forming a single element therewith. In order to obtain a solution which is advantageous in terms of construction and handling, bearing journal sections (6') of the hand lever (6) are suspended in open slits (9), loaded by the compression force of the spring (15) towards a slit end, and the opening (O), which is partially surrounded by the frame-shaped connecting tractional member (G) in the longitudinal direction of the pump, can be pivoted, on the hand lever side of the compressed spring (15), on the end (25) of the supporting tube (26) which is to receive the mouthpiece (23).

00044 This task is first and foremost

00045 a pump with the features of claim 1 solved,

00046, which is based on the fact that trunnion sections of the hand lever are suspended in open slots,

00048 loaded by the compression force of the compression spring

00049 slot end and that in the longitudinal direction of the pump,

00050 at least partly from the frame-shaped connection

00053 mounting tube is pivotable. The pump column

00054 ben is drawn into the linear leading pump chamber

00055 gen. The frame-shaped connecting link serves as

00056 assembly handle. Because of the opening, this can be done

00057 practically flap-like structures over the end of the support

00058 swivel pipe. The whole thing happens against the pressure

00059 force of the preloaded, supported on the housing side

00128 twists secured what the desired smooth running

00129 the pump delivers. With regard to the spring, there is a

00130 advantageous central system if the compression spring as in

00131 of the pump chamber lying truncated cone spring

00132 is. Should such a compression spring not be the one to be sprayed

00133 exposed liquid in a contacting manner

00134, an advantageous variant is that

00135 the compression spring as an integral

00136 gral realized with the housing trained leaf spring

00177 shorter length of the distance between the stops

00178 of the spring chamber as the basic length of the screw thread - 00179 compression spring. Regarding the pump mechanics

00186 is essentially radial to said direction

00187 extending flange forms. Such a radially abra-

00341 A bottle 1 is shown in the standing position. The

00342 Bottle interior 2 contains sprayable and foamable

00343 liquid 3. For the appropriate application

00344 a spray pump, referred to throughout as Pump 4. 00345

00346 The pump 4 is placed on the neck 5 of the bottle 1.

00347 sets. As shown, this can be more screwdriving

00348 Art be realized, also by bouncing or under

00349 Use of a bayonet lock. To refill the 00350 bottle 1 with liquid 3 is preferably a reversible

00351 sible assignment of pump 4, a so-called trigger

00352 pump, before. 00353

00354 The actuator of the pump 4 is a hand lever 6.

00356 oriented bearing pin 7 pivotally mounted. Body-

00357 can be loaned, provided on the hand lever 6

00358 acting stub axles (see Figure 13),

00359 or a special, congruent lying passage

00360 breaks or holes of the hand lever 6 penetrating

Act 00361 thru axle (see Figures 2 and 7). 00362

00363 In both cases the bearing pins 7 are in a bearing

00364 pin section 6 'of the hand lever 6 realized. The

00365 bearing for the bearing pin 7 is from a housing 8

00366 the pump 4 formed. 00367

00368 The bearing is designed as a horizontal slot 9. It

00369 is a paired slot 9, see above

00419 facing ring flank forms the fixed abutment for

00420 the larger diameter base turn of the truncated cone

00421 migen compression spring 15. Due to the helical shape

00422 the compression spring 15 in association with its piston side

00423 taper there is sufficient undisturbed movement

00424 space for the end face 18 of the pump piston 13. 00425

00426 The wall projection 19 leads to one

00427 intermediate pipe section 20 of the housing 8 of the pump 4. 00428 whose clear diameter is significantly below that of the 00429 pump chamber 17th

00430

00431 The intermediate pipe section 20 then goes into a white

00432 the reduced, coaxial pipe section 21 over

00433 lend a central channel 22 towards one in the

00434 drawing left-hand mouthpiece 23 of the pump 4. About

00435 said channel 22 reaches the pump-conveyed liquid

00436 speed 3 to a mouthpiece nozzle 24. The

00437 pipe section 21 with its free end 25 a support tube

00438 26 for the mouthpiece 23. 00439

00440 To hold the mouthpiece 23 on the end 25 of the

00441 support tube 26 is a clip connection applied. The

00442 clip means are designated 27. It is a matter of

00443 fins that can be run over on the jacket wall of the support tube

00444 26. The antidote to the rib is a groove

00445 in a pump chamber side connector 28 of the limited

00446 rotatable mouthpiece 23 seated on the support tube 26.

00447 The rotary end positions are limited so that the mouth

00448 piece 23 in a closed position with respect to the oral

00449 piece nozzle 24 can be brought. The means in this regard

00450 are common and should not be explained further here

00451. 00452 00453 Housing side, lying behind the wall, which the

00454 central mouthpiece nozzle 24 (see FIGS. 8 and 9),

00455 is a vortex chamber 29. They go head-on

00456, peripheral to the flow access to liquid

00457 speed 3 connected cross channels 30 to. They walk

00458 tangentially into the vortex chamber 29, which is circular in the base

00459 a. 00460

00461 According to variant Figure 8, two are practically diametrical

00462 opposite transverse channels 30 realized. 00463

00464 In the object according to FIG. 9 there are four at the same angle

00465 distributed transverse channels 30, also in

00466 tangential type of access

00467 provided whirling chamber 29. 00468

00469 It can also be seen from said FIGS. 8 and 9 that

00470 the tangential supply via longitudinal channel sections 31

00471 goes. They are in the supply connection to the central

00472 channel 22 of pump 4 and are on a cylindrical,

00473 central core piece, which is held by radial 00474 webs on the mouthpiece 23.

00475

00476 A barrier wall formed by a second nozzle 32

00477 controls the supply in the sense of the barrier

00478 or release. 00479

00480 Within the given by the wall recess 19

00481 chamber of the intermediate pipe section 20 is an inlet valve

00482 to VI added. That opens in the pump chamber

00483 17 developing negative pressure and closes there -

00484 menden, overpressure generated by the piston movement. 00485

00486 coaxial upstream of the inlet valve VI on the mouthpiece side

00487 tet, there is an outlet valve V2. That extends 00488 in the transition area there to the pipe section 21,

00489 which with its inner wall provides the valve seat 00490. Specifically, the outlet valve V2 is one

00491 elastic ring lip formed. It is in funding direction

00492 device of the liquid 3 peripherally backflow. In

00493 The opposite direction is at the inlet valve VI

00494 if a ring lip. This is only in the sense of

00495 lens of the pump chamber 17 from its from the inner wall

00496 of the intermediate pipe section 20 as a valve seat surface

00497 can be lifted off, i.e. flowable behind 00498

00499 inlet valve VI and outlet valve V2 are in one piece

00500 trained. They consist of resilient material

00503 The bottom of the outlet valve V2 is as in the direction of the

00504 pump chamber 17 exposed truncated cone body 33

00505 trained. It also acts as an assembly aid,

00506 by a tube R inserting it clamping the jacket wall

00507 recorded mend. Reference is made to FIG. 12. There is

00508 also recognizable that to form a after a

00509 cylindrical lateral surface aligned detection

00510 structure still balancing ribs 34 on the jacket

00511 wall of the truncated cone body 33 are formed. It

00512, for example, three

00513 arranges, four are shown. 00514

00515 At the foot of the truncated cone body 33 are

00516 broken passages 35 taken into account. Over this

00517 reaches the liquid 3 in the central channel 22. 00518

00519 What the absorption of the liquid to be dispensed 3

00520 relates, there is a throughflow opening 36 in this

00521 bottle-side wall part of the pipe intermediate

00522 Section 20 is taken into account. It connects to that 00523 interior of a nozzle 37. This in turn is with a

00524 riser 38 connected, the free end to

00525 bottom of bottle 1 is sufficient, having a structure that cannot be sustained 00526 there.

00527

00528 The hand lever-operated pump 4 has a double man

00529 greasing piston as a pump piston 13. Its two axially

00530 spaced cuffs tapering in annular lips

00531 39 leave an annular space 40 between them

00532 in the basic position of the pump 4 Connection to an aeration

00533 opening 41 of the housing 8 of the pump 4. He (40)

00534 holds the ventilation opening 41 closed. The ventilation opening

00535 41, on the other hand, is passed over in a slider-like manner

00536 by operating the pump 4. The ventilation opening 41

00537 then connects to the bottle-

00538 inner 2nd The underside of the pump chamber 17 is the

00539 pump cylinder 12 integrally formed a nozzle 42, which

00540 merges peripherally into a screw cap 43, which with the

00541 neck 5 of the bottle 1 can be sealingly connected. 00542

00543 The valve slide valve

00544-like acting pump piston 13 occurs under actuation

00545 of the same finally from the area of ventilation

00546 opening 41 that this then takes on connection

00547 a channel 44, made from the open end on the right

00548 14 of the pump cylinder 12.

00550 instead. 00551

00552 The hand lever operated displacement of the pump piston

00553 13 in the pump cylin-

00554 of Figure 12 is linear. With the direction of the pump

00732 is. Folded out of the way and tied up

00733 the spray jet generated. 00734

00735 Deviating from the basic version, it can look like that

00736 Figure 4 shows the compression spring 15 as an external,

00737 i.e. spring lying outside the pump chamber 17

00738 forms. This is substantiated according to FIG.

00739 in that the compression spring 15 as the hand lever 6 in basic

00740 position acting leaf spring is formed. 00741 The starts from the mouth wall area of the

00742 nozzle 42, initially runs essentially hori-

00743 zontal, to end in a downward arc shape from half its length. The end of the leaf spring

00745 lies in the pocket-forming U-section of the hand lever

00746 6 guided and protected, specifically on the trigger

00747 end arm b, more precisely on the inside of the U-bridge. 00748

00749 Figure 5 illustrates a variant such that

00750 the compression spring 15 is a bow spring. Figure 6 shows

00751 the double leg of the relevant leaf spring

00752-like compression spring 15. The legs are weakly curved

00753 shaped from the dead center line between the attachment point

00754 and actuation point of attack issued. Your ela-

00755 resilient, resilient legs wear that

00756 reference numeral 56. The mouthpiece-side fastening

00757 dot is a vertically aligned eye on the spring side

00758 57. This is on a locking pin 58. It has one

00759 axial slit and holds with one end

00760 mushroom head the compression spring 15 in position. The free

00761 ends of the legs 56 engage in receptacles of a transverse

00762 ches 59 of the frame-shaped connecting tension member G. 00763

00764 The external compression springs 15 are also preloaded. 00765 00766 The spray pump with bottle 1 according to the second embodiment

00767 example (Figure 14 ff) is of the same structure as that

00768 in detail embodying the first embodiment

00769 discussed basic version. The reference numbers are so far

00770 required for understanding, applied analogously, this

00771 partly without repeated text. 00772

00773 While in both exemplary embodiments the bearing journal

00774 fen sections 6 'of the hand lever 6 basically in

00775 open slots 9 are suspended, loaded by the

00776 pressure force of the compression spring 15 to the inner slot end

00777, the slots 9 are still open in opposite directions,

00778 this due to the fact that on the second embodiment

00779 example a reversal of funds is applied, i. H.

00780 the pair of bearing pins 7 are located on

00781 housing 8; the slots 00782, also designated here by 9, are formed on the hand lever 6, specifically in the area 00783 of the journal sections 6 ¹ .

00784

00785 The bearing pins 7 formed in the same way are crescent

00786 like. Her circular back is covered by a sledge

00787 geometrically encircled so that the slot

00788 gears have a smaller clear width than the 00789 diameter of the crescent-shaped bearing pins 7

00790 carries. The towards the effective pressure force of the

00791 compression spring 15 opening is shown, for example, in the figures

00792 ren 20 and 21 emerge. 00793

00794 That the slots 9 in the direction opposite to the pressure force

00795 of the compression spring 15 open and on the housing 8 of the pump

00796 4 are shown in FIG. 10, for example. 00797

00798 A further design feature of the spray pump

00799 according to the second exemplary embodiment is then a further

00800 re variant of the external mounting of the compression spring 15. 00801 It is such a liquid contacting insert

00802 tion withdrawn. It is recognizable as outside the

00803 pump chamber 17 lying compression spring with free actuation

00804 access access realized. As accessible for operation

00805 is the one in the drawing, in the drawing

00806 right-hand end turn of the screw-shaped

00807 compression spring 15. This end has the reference numeral

00808 60. The other end, provided by the local endwin

00809 fertilizer the compression spring 15, is designated 61. It

00810 is closer to the mouthpiece 23. 00811

00812 The compression spring 15 is in a cartridge chamber-like,

00813 housed elongated spring chamber 62. Their geome-

00814 trical longitudinal axis y-y extends parallel to the space

00815 above the explained line x-x. She (62) is part

00816 lig formed from a fixed section of the housing

00817 ses 8 and a movable portion of the actuation

00818 chanik. The housing-side section is a through

00819 parallel side walls of limited shaft; the

00820 movable section represents an overlapping it

00821 cover 64. The sections describe an im

00822 Essential prismatic cross-section in which

00823 the compression spring 15 with sufficient side play, however

00824 protected against buckling, is included. 00825

00826 The bottom of the shaft 63 can, as can be seen in FIG.

00827 goes on, have a longitudinally extending ridge 65

00828 which the compression spring 15 slidably rests on. In adaptation

00829 on the spring cross section, the comb is 65

00830 differently shaped or completely omitted. 00831

00832 The cover 64 is the frame-shaped connecting train

00833 member G molded. 00834 00835 The compression spring 15 is only partially visible

00836 inside or below the cover 64.

00837 This is the indicated free actuation access

Given 00838 the compression spring 15. This is substantiated in the

00839 individual in that on the frame-shaped connecting train

00840 limb G is an actuation acting via the free access

00841 gungsfinger 66 is formed. That goes in the

00842 Cross-sectional area of the compression spring 15. It overlaps

00843 the end 60 of the same. 00844

00845 The application finger 66 sees a paired

00846 build before. This is clearly shown in Figure 18.

00847 It can also be seen there that a horizontal

00848 cut on the upper, horizontal forehead

00849 that of the walls delimiting the shaft 63 laterally

00850 is guided supported. Outside of these walls

00851 closes a vertical

00852 cut the application finger 66 to one

00853 diagonally outward sloping connection

00854 section, which finally enters the

00855 tensile leg 46 of the frame-shaped connecting tension member

00856 of the G arrives. The horizontal sections of the

00857 striking fingers 66 extend substantially into

00858 of diametrals of circular cross-section have

00859 den, cylindrical compression spring 15. 00860

00861 The ends of the horizontal sections of the

00862 striking fingers 66 leave a gap between them

00863 e.g. The meaning of such a gap-like distance

00864 finger will be explained later. 00865

00866 The prestressed recording of the compression spring 15 in the

00867 spring chamber 62 is based on the intercalation

00868 stationary, defining the length of the spring chamber 62

00869 stops of the spring chamber 62. 00870 end 60 facing stop is designated 67

00871 net; the closer to the mouthpiece 23, the abutment

00872 for the other end 61 of the compression spring 15

00873 impact bears the symbol 68. Regarding both stops

00874 67, 68 is perpendicular to the longitudinal axis y-y

00875 running cheeks protruding upwards. The

00876 are rooted in the tube section 21 of the central channel 22

00877 of the pump 4. 00878

00879 The degree of preload of the compression spring 15 depends

00880 then how short the effective distance between the

00881 stops 67, 68 compared to the basic length of the

00882 th helical compression spring 15 is selected, corresponds to

00883 chend the feature that the bias of the compression spring

00884 15 by a shorter length of the distance between

00885 stops 67, 68 of the spring chamber 62 is reached as

00886 the length of the compression spring 15. On the corresponding

00887 pre-compression does not apply to about 1/10 of the spring length. 00888

00889 While regarding the connection closer to the mouthpiece 23

00890 ges 68 the full inside width of the spring chamber

00891 mer can be applied is the horizontal width of the

00892 of the pump chamber 17 closer stop 67 clearly

00893 borrowed. The corresponding deduction is

00894 stalt that the stop 67 is slightly smaller than that

00895 width of the horizontal gap z between the

00896 fingers is 66. The application fingers 66

00897 can thus said stop 67 on the pump chamber side

00898 overflowed. In other words: close to the pump chamber

00899 end 60 of the spring takes place unaffected by the

00900 loading finger 66 its support at the stop

00901 67 in the basic position of this hand lever operated pump

00902 pe. Reference is made to FIG. 19. The Beaufschla-

00903 gungsfinger 66 step into the area of the mantle

00904 before the cross-sectional size compared to the pipe section 21 00905 outer pipe intermediate section 20 and ends, given

00906 if used, in front of the wall projection 19 of the

00907 housing 8. In this position is the towering

00908 Part of the cover 64 with its pump chamber side

00909 forehead at the level of the stop 68 there, which also

00910 with regard to the front end

00911 leads can be. The forehead facing the mouthpiece 23

00912 end of cover 64 is in the dimensions of the actuating

00913 bes 69 of the pump mechanics in the basic position of the pump 4

00914 from the stop there 68. With the hand lever actuated

00915 6 this front end occurs, as can be seen from FIG. 20,

00916 acts against the stop there

00917 68. The further the application fingers 66 the pressure

00918 of the 15 compress, the more the spring body occurs

00919 increasingly and finally completely below the chamber

00920 cooperation of the cover 64. The compression spring is like this

00921 is supported radially and cannot come out of the spring

Bend out 00922 mer 62. 00923

00924 The further function of the manually operated spray pump

00925 will not be explained further here, since it is

00926 from the description of the basic version or the

00927 of the first embodiment. 00928

00929 The stops 67 and 68 are in their respective backs

00930 by means of a support

00931 strut 70 stabilized, so that highly thin-walled

00932 can be worked. 00933

00934 With regard to the hand lever 6 of the pump 4 is on the

00935 further training measure that the slots 9

00936 the journal sections 6 ^{1 of} the hand lever 6 with in

00937 direction of the compressive force of the compression spring 15 lying

00938 opening is formed, the measure still taken

00939 that the circular segment-shaped slot end through 00940 an angled flange collar 71 widened the area

00941 is. The slot end no longer shows the wall thickness

00942 ke of the U-shaped cross-section hand lever 6

00943 on, but a proportional width, which from the anyway

00944 existing clear distance between the U-legs

00945 of the hand lever 6 is obtained. The flared collar 71

00946 can look like a keyhole in the area of

00947 narrowed opening, i.e. slot entrance continue

00948 zen. The desired stabilization is still increased

00949 by the measure that the hand lever on the slot end

00950 material also from the area of the U-leg of the

00951 U-shaped cross-section hand lever 6 beige

00952 is drawn, which material in the manner of a curved strip 72

00953 is pulled against the back of the flanged collar 61 (it

00954 may be referred to FIG. 19, for example). 00955

00956 In the second exemplary embodiment, too, inlet valves are

00957 til VI and exhaust valve V2 as an integral component

00958 realized, further referred to as insert 73. Das

00959 lies in one of the pump chambers 17 in the direction of the

00960 mouthpiece nozzle 24 upstream antechamber 74, in which it, 00961 using the entire length of the same, is received in a protected manner. Since the compression spring 15 from the pump chamber

00963 is installed, the wall projection 19 is now between

00964 the intermediate pipe section 20 and the pump cylinder 12

00965 free inside. Using this is the usual one

00966 Lip-carrying end section of the intake valve VI

00967 now extends such that it enters the pump chamber

00968 17 protrudes. The inlet valve VI is now one

00969 molded lip extending radially, specifically in

00970 shape of an annular flange 75. The radial

00971 direction having a multiple of a wall thickness

00972 wall offset with its step surface 19 '

00973 now the corresponding valve seat surface of the

00974 inlet valve VI. 00975 The flange can still be reduced in wall thickness

00976 compared to the general wall thickness of the insert

00977 partly 73. This is according to the drawing

00978 also practiced in this way. The flange 75 itself has

00979 has the smallest thickness, which approximately doubles in the cylindrical part 00980 of the initial area of the pot section of the insert part 00981 and 73 in the remaining wall area has the size 00982 three to five times. This makes 00983 a favorable compromise between a high one

00984 inherent stability, which also makes assembly safe and

00985 the desired ease of folding of the flange 75, the

00986 with pre-tension on the valve seat surface

00987 step surface 19 "of the Waridungsversprung 19. 00988

00989 In the insert 73 according to the further development, the central

00990 le, flow-dividing frustum 33

00991 omitted. The cylindrical pot shape is rather

00992 kept clear. To also refer to the inside of the

00993 pre-chamber 74 extending pump chamber 17 with respect to

00994 liquid 3 to be removed as completely as possible

00995 men, is the measure taken that the pump

00996 piston 13 in the actuating end position (Figure 20)

00997 throughflow area of the insert part 73, 00998 displacement projection 76 is formed. It is rooted in

00999 the transition point between the end cuff

01000 39 of the pump piston 13 in the pot body of the pump piston

01001 bens and is designed as a

01002 jump realized. The transverse floor 16 is practical

01003 according to the basic version in the transition area to the cuff

01004 te 39 advanced. The board is dimensioned so that

01005 with impact of the cuff 39 in the periphery of the

01006 flange 75 occupies the interior of the insert 73

01007 is. The liquid 3 is through the passages 35

01008 flowing, with outlet valve V2 in

01009 pushed the central channel 22. 01010 The valve function of the further training should not be here

01011 can be repeated as they are the basic version

01012. 01013

01014 Because of the described forward displacement of the transverse floor

01015 the pump piston 13 is open towards its rear side 49

01016, there is also a manufacturing

01017 partial possibility, which is used in such a way

01018 that the pump piston 13 on the frame-shaped connection

01019 tension member G freely accessible via flexible connection

01020 sections 77 connected between spraying

01021 Form position (see connection tension member G in figure

01022 15) and mounting position (see Figure 17) in any case

01023 swiveling between pump piston 13 and connection

01024 tension member G of 90 ° enables. The corresponding win

01025 kel Alpha is entered in Figure 15. Recognizable lies

01026 the cavity of the pump piston 13 over the connecting

01027 end section of the opening Ö of the train

01028 link G freely accessible for mold and demoulding. The jetty

01029 48 is designed as an arch leg. One is educated

01030 film hinge, comparable to the one labeled 50

01031 basic version. The connecting sections 77 extend

01032 no longer runs continuously across the length of the

01033 web 48; rather, the connecting sections 77 are located

01034 in a common transverse plane in the pump piston slide 01035.
