Abstract
Description
- The present invention relates to manual guns for the spraying application of coating substances such as paints, chemicals and the like.
- More in particular the invention relates to a spray gun of the type comprising a body having a union for the inflow of a substance to be sprayed, whereto is able to be connected a cup containing the substance to be sprayed and having an outflow union designed to be coupled with said inflow union through removable connecting means.
- Traditionally, the removable coupling between the inflow union of the gun body and the outflow union of the cup is achieved by means of a screw-on system: more in particular, through an external thread whereof is provided the inflow union of the gun body whereon is screwed an internal thread of the outflow union of the cup or, alternatively, by means of an external thread of the outflow union of the cup which is screwed into an inner thread of the inflow union of the gun body.
- This traditional connection system has essentially two problems.
- In the first place, the screwing and unscrewing between the cup and the gun body require a relatively long and inconvenient operation.
- In the second place, with this system, which is technologically simple and hence easily reproducible, there is the risk that the guns of a given manufacturer may be equipped with cups not produced by the same manufacturer, i.e. not original. In this case, it is possible that non original cups may induce an improper operation of the gun, and otherwise an operation that does not correspond with the use of the original cups for which the gun was designed.
- To attempt to result this second problem, the international patent application WO-03/069208 proposes a particular removable system between the cup and the pistol, which provides a threaded coupling with a wedge system between the inflow union of the gun body and the outflow union of the cup. However, this system, in addition to being relatively complicated from the constructive viewpoint, does not solve the first problem outlined above, but in fact complicates it further.
- The object of the present invention is to provide a simple, economical and functional solution to both technical problems described above.
- According to the invention, this object is achieved thanks to the fact that the aforesaid removable connection means between the inflow union of the gun body and the outflow union of the cup containing the substance to be sprayed comprise a bayonet coupling to which a safety device for the positive locking of said bayonet coupling in the coupled condition is operatively associated.
- According to a preferred embodiment of the invention, the aforesaid safety device includes a ring nut able to rotate coaxially to the inflow union of the gun body for the arrest in rotation between said inflow union and said outflow union in the coupled condition of said bayonet coupling.
- Moreover, the injection union of the gun body and the outflow union of the cup have peculiar complementary profiles which assure their precise sealed mutual coupling eliminating, during the operation of the gun, risks of leaks of the substances to be sprayed.
- The invention will now be described in detail in reference to the accompanying drawings, provided purely by way of non limiting example, in which:
- Figure 1 is an exploded schematic view of manual spray gun according to a first embodiment of the invention,
- Figure 2 is an axial section view, in enlarged scale, showing the connection area between the body of the gun and the cup of the substance to be sprayed,
- Figure 3 is an exploded perspective view of Figure 2, and
- Figure 4 shows a variant of Figure 1.
- Initially referring to Figure 1, the
number 1 designates the body of a gun for spray painting, provided posteriorly with agrip 2 and anteriorly with a generally conventionalnebuliser nozzle 3. - In the upper part of the
gun body 1 is formed atubular boss 4 communicating with a feeding conduit, not shown, connected in known fashion to theatomising nozzle 3. - Into the
boss 4 is permanently inserted, for example screwed, atubular inflow union 5 adapted for the removable sealed connection of acup 6 containing the substance to be sprayed by means of thegun 1. In the case of the illustrated example, the substance to be sprayed contained in thecup 6 is in use fed to the gun by gravity, placed in upside down position above thegun 1. - As shown in detail in Figures 2 and 3, the
inflow union 5 has acylindrical terminal portion 7, an intermediate portion with conicalinner surface 8 and an initialcylindrical portion 9 with narrowed conformation, i.e. having reduced cross section with respect to that of thecylindrical terminal portion 7. - The edge of the free end of the narrowed
initial portion 9 has an annular inner narrowing withconical surface 10. - The
cylindrical terminal portion 7 is formed with a pair of diametricallyopposite slits 11, each whereof has, as shown in detail in Figure 4, a general "L" shape with an axially directedupper segment 12 and an inclined or generally horizontallower segment 13. - The
reference 14 designates a ring nut which coaxially surrounds in rotatable fashion thecylindrical terminal portion 7 of theinflow union 5 and is axially movable relative thereto for a downwards travel, i.e. the initial narrowedportion 9, by an extend that is limited inferiorly by an arrestingring 15. As Figure 3 shows in detail, thering nut 14 is formed on its inner wall with anannular groove 16 communicating with a pair of diametrically oppositeaxial grooves 17, whereof one is shown in Figure 3. - The
cup 6 shown in Figure 1 is generally conventional and consists of a container of generally cylindrical shape, for example metallic or made of moulded plastic material, provided at an end with aremovable lid 18 which may have an opening andaerial valve 19, and formed at the opposite end with a generally funnel shapedbottom 20 provided with anaxial outflow union 22 able to be coupled in sealed, removable fashion with theinflow union 5 of thegun body 1, in the manner made more readily apparent below. - Referring now in greater detail to Figures 2 and 3, the
outflow union 22 has a complementary shape to the inflow union 5: in detail, it comprises a broadened cylindricalinitial portion 23, complementary to thefinal portion 7 of theinflow union 5, an intermediate portion with conicalouter surface 34 complementary to the conicalinner surface portion 8 of theinflow union 5, and acylindrical terminal tang 24, complementary to theinitial portion 9 of theinflow union 5. - The
terminal tan 24 of theoutflow union 22 has at its free end an externally enlargedannular edge 25 with a conicalouter surface 26 complementary to theconical surface 10 of theinflow union 5. - As shall be described below, one or the other of the
conical surfaces - The
reference number 27 designates a radial pin or stake which traverses the broadened cylindricalinitial portion 23 of theoutflow union 22 and whose opposite ends project externally thereto. It should be noted that the throughpin 27 could be replaced with two distinct and separate pins, projecting outside two diametrically opposite areas of the initialcylindrical portion 23, in a wholly equivalent manner at the opposite ends of said throughpin 27. It should also be noted that, instead of two diametrically opposite projecting pins, a single pin could also suffice, projecting radially outside the initialcylindrical portion 23. In this case, thecylindrical terminal portion 7 of theinflow union 5 may be provided with a single L shapedslit 11 and, similarly, thering nut 14 may be provided with a singleaxial groove 17. - With the above described arrangement, the removable connection between the
outflow union 22 of thecup 6 and theinflow union 5 of the gun is achieved, according to the peculiar characteristic of the invention, through a bayonet coupling with associated safety device for its reversible locking. - Said bayonet coupling is in practice constituted at one side by the opposite projecting end of the
diametrical pin 27 of theoutflow union 22, and at the other by the L shapedslits 11 of theinflow union 5, whilst the safety device is constituted by the rotatable andslidable ring nut 14. - To achieve the coupling between the
cup 6 and thegun 1 it is simply necessary, starting from the configuration shown in Figure 1, to introduce axially theoutflow union 22 into theinflow union 5, until the abutment between theconical surfaces pin 27 are introduced into theaxial portions 12 of theslits 11. Then, rotating theunions pin 27 are made to slide along theportions 13 of theslits 11, until positioning themselves in correspondence with their terminal ends: the bayonet coupling between theunions conical surfaces unions - To proceed with the positive locking of the bayonet coupling, it is therefore simply necessary axially to position the
safety ring nut 14 engaging the projecting ends of thepin 27 into theaxial grooves 17, and then to rotate saidring nut 14 to engage the ends of thepin 27 into theannular groove 16. - In this way, all risks of accidental or undesired disengagement between the
cup 6 and thegun 1 are prevented. - To remove the
cup 6, it will thus be sufficient to disengage thesafety ring nut 15 from the projecting ends of thepin 27 and then disengage said ends of thepin 27, first by rotation and then axially, from theslits 11. - The bayonet coupling system with positive safety locking described above is applicable not only to
conventional cups 6, but also to disposal cups, such as the one designated by thereference number 28 in Figure 4, in which parts that are identical or similar to those already described above are designated by the same numerical references. - According to said variant, the
cup 28 comprises adisposable container 29, normally made of moulded plastic material, and theoutflow union 22 is borne by a substantially funnel shapedbottom 30 separated from thecontainer 29 and connected in removable fashion thereto by means of aring nut 31. The arrangement of thecup 28 could be, for example, of the type described and illustrated in European patent application no. 03026312.3 by the same Applicant, not published as of the priority date of the present application. Otherwise, it may be of the type currently produced and marketed by the same Applicant with the commercial name "Mix & Spray Cup". In this case, the funnel shapedbottom 30 with theoutflow union 22 may in practice constitute an integral part of the body of thegun 1, in the sense that it may remain permanently coupled to the gun by means of the bayonet coupling and the safety locking between theunions - As an additional alternative, the funnel
shaped bottom 30 can be disposable like the container 29: in this case, theoutflow union 22 may also be, with the or with each projecting radial pin for the engagement of the or of each L-shaped slit 11, integrally formed by moulding of plastic material withsaid bottom 30. - Naturally, the construction details and the embodiments may vary widely from what is described and illustrated herein, without thereby departing from the scope of the present invention as defined in the appended claims.
