CARTRIDGE TYPE ONE-HANDED LEVER ACTUATED GREASE GUN AND GREASE
CARTRIDGE
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a charging gun and in particular to a tube type one-handed lever actuated liquid charging gun and cartridge type one-handed lever actuated grease gun and grease cartridge.
Related Art
Tube type lever operated liquid charging guns which are capable of supplying chemicals such as insecticides and lubricating oils such as grease under pressure are used in various fields. A typical example of such a tube type lever operated liquid charging gun is shown in Fig. 7.
In the drawings, the lever operated liquid charging gun 30 mainly comprises an outer cylinder 32, a cap 34 having a cylinder chamber 34a and a plunger 34b, which is detachably secured to the head of the outer cylinder 32, a liquid charging nozzle 36 secured to the cap 34, a link 38 which is pivotally secured to the cap 34 and a lever 40 which is pivotally secured to the plunger 34b and the link 38.
The cap 34 comprises a tube connecting slot 34c to which the neck of the tube 42 can be detachably fitted, a liquid charging nozzle connecting slot 34d to which the connecting portion of the liquid charging nozzle 36 can be sealingly fitted, a liquid passage 34e which communicates the cylinder chamber 34a with the tube connecting slots 34c and the liquid charging nozzle connecting slot 34d and a check valve 34f provided on a position along the length of the liquid passage 34e between the cylinder chamber 34a and the liquid charging nozzle connecting slot 34d.
The tube type lever operated liquid charging gun is capable of supplying liquid to be charged from a tube which containing the liquid. Accordingly, this type of gun is easier to replenish the liquid than guns to which the liquid is manually replenished and is capable of supplying the liquid without exposing the liquid to external atmosphere. Therefore, it is widely used.
However, the above mentioned prior art lever operated liquid charging gun 30 is arranged to pump the liquid outside from the cylinder chamber 34a by shifting the lever 40 to reciprocate the plunger 34b within the cylinder chamber 34a with one hand while holding the outer cylinder 32 with the other hand. Accordingly,the lever operated liquid charging gun 30 can not be used at places where the gun 30 can not be held with both hands.
Since the liquid charging nozzle 36 points in a direction parallel with the longitudinal direction of the outer cylinder 32 in the above mentioned prior art lever operated liquid charging gun 30, the nozzle 36 should be replaced with a hose type charging nozzle when the liquid is charged in a direction normal to the longitudinal direction of the outer cylinder 32. This implies that various types of charging nozzles are preliminarily provided. This is inconvenient. Further, a bellows type tube is used in the above mentioned prior art lever operated liquid charging gun 30. The liquid left in the central portion of the bellows type tube in even when the volume of the tube becomes minimum. The amount of the residual liquid is 3 to 10 % of the full amount of the liquid to be contained in the bellows type tube. The tubes are generally disposal.Three to ten percents of the liquid charged in the tube are always disposed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Now, the tube type one-handed lever actuated liquid charging gun, the grease cartridge type one-handed lever actuated grease gun and the bellows type grease cartridge used for said grease gun of the present invention will be described with reference to the drawings.
Referring now to Fig. 1, there is shown a front view of one embodiment of the grease cartridge type one-handed lever actuated grease gun of the present invention. Fig. 2 is a longitudinal sectional view of the grease gun of Fig. 1.
The one-handed lever actuated grease gun 10 shown in
Figs. 1 and 2 mainly comprises an outer sleeve or cylinder 12; a ca p 14 having a cylinder chamber 14a and a plunger 14b, which is detachably secured to the head of the outer cylinder 12; a charging nozzle 16 mounted on the cap 14; a link 18 which is pivotally mounted on the cap 14; a lever 20 which is pivotally mounted on the plunger 14b and the link 18; and a spring 24 mounted on a pin 21 which pivotally supports the link 18 and the lever 20.
The outer cylinder 12 is adapted to accommodate the bellows type grease cartridge 22 which is charged with grease and has an elongated viewing window 12a on the upper portion of the side thereof. The level of the grease in the grease cartridge 22 can be viewed through the viewing window 12a. In the other embodiment of the present invention shown in Fig. 3, the outer cylinder is roughed at 12b on the outer surface thereof to prevent the hand from slipping thereon.
The cap 14 has the cylinder chamber 14a which extends in a direction normal the longitudinal direction of the outer cylinder 12 and the plunger 14b which can be reciprocated within the cylinder chamber 14a.
The cap 14 is provided on the lower portion thereof with a grease cartridge connecting slot 14c. The slot 14c is formed on the inner side thereof with an internal thread which can be threaded with an external thread formed on the neck of the grease cartridge 22. A first grease passage 14e is formed between the grease cartridge connecting slot 14c and the cylinder chamber 14 for fluidly communicating them with each other.
The cap 14 is provided in the upper portion thereof with a charging nozzle connecting slot 14d which directs in a direction normal to the longitudinal direction of the outer cylinder 12. The nozzle connecting slot 14d is formed on the inner side with an internal thread which is threaded with an external thread on the connection of the charging nozzle 16. A second passage 14e is formed between the nozzle connecting slot 14d and the cylinder chamber 14a for fluidly communicating them with each other.
The cap 14 is formed in the upper portion thereof with a check valve mounting hole 14g which extend in a direction parallel with the longitudinal direction of the outer cylinder 12 so that the hole 14g is in communication with the second fluid passage 14e. A check valve 14f comprising a ball and a spring for biasing the ball at a given pressure is disposed in the check valve mounting hole 14g so that it is located at the interface between the hole 14g and the first fluid passage 14e. The check valve mounting hole 14g is formed on the inner side thereof with the same internal thread as that formed in the nozzle connecting slot 14d. A seal member 14h which seals the check valve mounting hole 14g is formed on the outer side thereof with the same external thread as that formed on the connection of the nozzle 16.Accordingly, the nozzle 16 and the seal member 14h are exchangeable with each other. This makes it possible to charge grease in both directions which are normal to and parallel with the longitudinal direction of the outer cylinder 12 by the use of only one nozzle 16.
The cap 14 is formed on the upper surface thereof with a projection 14i which projects upward. The link 18 is pivotally mounted on the projection 14i via the pin 17 at one end thereof.
The lever 20 is pivotally mounted at one end thereof on the other end of the link 18 via a pin 21. In an alternative embodiment of the present invention shown in
Fig. 3, the lever 20 is formed with concaves 20b corresponding to fingers on the outer side of the lower portion thereof.
The lever 20 is pivoted on one end of the plunger 14b via a pin 19. The lever 20 is formed in the upper portion thereof with an opening 20a through which the charging nozzle 16 passes. The lever 20 is smoothly curved at the lower portion thereof in such a manner that it can be easily gripped with a hand.
Since the lever 20 is pivotally mounted on the projection 14i of the cap 14 through the two pins 17, 21 and the link 18, the plunger 14b can be reciprocated within the cylinder chamber 14a.
In the illustrated embodiment, the spring 24 is wound around the pin 21 so that it abuts on the link 18 and the lever 20 at the opposite ends thereof. Alternatively, the spring 24 may be disposed around the plunger 14b between the cap 14 and the lever 20 as is illustrated in Fig. 3 showing the alternative embodiment of the present invention.
Method of using the grease gun 10 shown in Figs. 1 and 2 and its operation principle will be described.
Prior to use of the gun, the neck of the grease cartridge 22 which is charged with grease is screwed into the grease cartridge connecting slot 14c to secure the grease cartridge 22 thereto.
The grease cartridge 22 is generally disposal type. The grease cartridges which comply with the Japanese Industrial
Standard JIS9808 are commercially available from, for example, N. G. N. Co., Ltd (Tokyo, Japan) who is the assignee of the present application as Models "Micro Multi
Grease for 800 grams" and "Micro Multi Grease for 400 grams".
Subsequently, determination which direction the nozzle 16Of the grease gun should be directed is made. If the gun 10 will be used with the nozzle 16 directing in the direction parallel with the longitudinal direction of the outer cylinder 12, the grease charging nozzle 16 and sealing member 14h are removed from the nozzle connecting slot 14d and the check valve mounting hole 14g, respectively and they are replaced.
Alternatively, in lieu of the standard type nozzle shown in-Figs. 1 and 2, a nozzle 26 having a flexible hose interposed in an intermediate position thereof as shown in
Fig. 4 and a nozzle 27 having a tapering front end as shown in Fig. 5 may be used. The nozzle 26 shown in Fig. 4 can be advantageously used for a grease nipple to be greased up even if it is directed in any direction. The nozzle 27 shown in Fig. 5 is advantageous in case where the grease nipple is located at a narrow place.
In no use of the gun, the spring 24 biases the plunger 14b in the cylinder chamber 14a to such an extended position that the cylinder chamber 14a can be in fluid communication with the grease cartridge connecting slot 14c.
When an operator grips the lever 20 while holding the outer cylinder 12 with one hand, the plunger 14b is pressed by the lever 20 to move in such a direction that the volume in the cylinder chamber 14a is reduced, that in a left direction as viewed in Fig. 2. After the plunger 14b has passed through the first grease passage 14e communicated with grease cartridge connecting slots 14c, the cylinder chamber 14a is closed excepting the second grease passage 14e communicated with the nozzle 16. Accordingly, when the plunger 14b is further moved in a left direction, the grease within the cylinder chamber 14a is pumped out there from the second grease passage 14e to the nozzle 16.
When the operator releases the lever 20, the lever 20 is moved to the extended position by the action of the spring 24, that is, in such a direction that the volume in the cylinder chamber 14a increases.
Since the pressure in the cylinder chamber 14a becomes negative by the plunger 14b after the plunger 14b has passed through the first grease passage 14e communicated with the grease cartridge connecting slot 14c, the plunger 14b causes the grease to be sucked from the grease cartridge 22.
Various grease cartridges other than those complying with the above mentioned Japanese Industrial Standard may be used as the grease cartridge 22 which is mounted on the grease gun 10.
Figs. 6a and 6b show such an example of the grease cartridge. Fig. 6a shows the grease cartridge, the volume of which is maximum by being filled with the grease. Fig.
6b shows the substantially empty cartridge, the volume of which is minimum by the consumption of the grease.
The grease cartridge 52 has a bellows like sleeve 52b and a bottom 52d including a cylindrical protuberance 52c which is displaced into the inside of the cartridge 52. The neck 52a is formed on the outer periphery thereof with an external thread which threaded with the external thread of the grease cartridge connecting slot 14c. A cap lid 54 is mounted on the neck 52a.
If a chemical which should not be exposed to atmosphere is charged, it is preferable to cover the opening of the neck 52with a covering which is readily torn when the neck 52a is screwed into the slot 14c.
In the tube type one-handed lever actuated liquid charging gun which is provided in the first aspect of the present invention, the spring means biases the plunger in the cylinder chamber to an extended position where the cylinder chamber is in fluid communication with the tube connecting slot. When the operator grips a lever with one hand while holding the outer cylinder, the liquid in the cylinder chamber is pressed by the plunger and is dispensed from the nozzle via the passage. When the operator releases the gripping force, the lever is returned to the extended position by the spring means. Accordingly, necessity to operate the gun with both hands as is done in the prior art liquid charging gun is eliminated. And operation at a narrow place is possible.
In the grease cartridge type lever operated one hand grease gun which is provided in the second aspect of the present invention, the nozzle connecting slot is directed in a direction normal to the longitudinal direction while the check valve mounting hole is directed in the direction parallel with the longitudinal direction of the outer cylinder. Accordingly, if the nozzle is mounted on the nozzle connecting slot directing in a direction normal to the longitudinal direction of the outer cylinder, the grease can be charged in a direction normal to the longitudinal direction of the outer cylinder via the nozzle.
If the connection structure between the nozzle and nozzle connecting slot is identical with that between the check valve mounting hole and the seal member, by mounting the nozzle on the check valve mounting hole directing in a direction parallel with the longitudinal direction of the outer cylinder, the grease can be charged in a direction parallel with the longitudinal direction of the outer cylinder via the nozzle.
Accordingly, the grease can be charged in either directions normal to and parallel with the longitudinal direction of the outer cylinder with aid of one nozzle.
In the bellows type grease cartridge which is provided in the third aspect of the preset invention, the bottom portion is cylindrically raised or projected so that it can be adapted into the inside of the grease cartridge. In a position where the inner volume of the cartridge becomes minimum, the cylindrical protuberance on the bottom of the grease cartridge occupies the central area in the grease cartridge. The amount of the grease which is disposed together with the grease cartridge is reduced by the amount equal to the volume of the cylindrical protuberance.
Material can be advantageously saved.
