Description

Description spray gun and accessories

The invention relates to an easy-to-clean spray gun.

Spray guns for paints, varnishes, adhesives or other flowable materials require careful cleaning of the material-carrying areas after each use or before each material change, if a cartridge, ie. a replaceable insert is used, which is preferably designed as a disposable article. Such an advantageous spray gun with a holding portion and with a head, which is equipped with a cartridge, wherein the cartridge has an inlet region for a material-carrying channel, which ends in an outlet region and wherein the inlet region of the cartridge connected to a reservoir for the material to be sprayed or is connectable and wherein the cartridge preferably leads at least one material-carrying component of the pointed gun, is known for example from DE 3016419 C2. This spray gun has a two-part head with a rear in the injection direction and a front in the spray direction area. The rear end of the front portion of the two-part head is provided with a plug-in seat for a cartridge having a spray-tube-extending tubular material-carrying channel, inside which a nozzle or paint needle is arranged. The

Nozzle needle can be reciprocated by means of a lever and spring mechanism in the spray jet direction, so that the material to be sprayed can pass through a nozzle arranged in the outlet region for processing. The cartridge is using

Plug pin connections held in the head. After use, the pin connections can be solved, the two head areas folded against each other, the cartridge including the paint needle removed from the head and then thrown away. Thereafter, a new cartridge can be attached to or in the spray gun. A cleaning of the material-carrying areas of the spray gun is unnecessary here. However, the pin connections are relatively complicated, difficult to manufacture and solve and also do not always ensure the problem-free reliability.

The object of the invention is to provide a spray gun of the type mentioned, which works reliably at any time and on or in particular a cartridge or other replaceable use less complicated, but securely attached and can be solved by her or from her , In addition, an object of the invention to provide an improved attachment means for cartridges or inserts in spray guns. To create use for spray guns. Another object of the invention is to achieve the best possible spray result using an air distributor.

The first object is achieved by means of a spray gun according to claim 1 or 2. By the rings according to the invention according to claim 1 or 2, a large-area connection of the cartridge is ensured with the spray gun, which can be easily solved again and possibly restored using a new cartridge.

The second object of the invention is achieved by a coupling ring according to claim 84, 85 or 86.

The third object of the invention is achieved by a cartridge according to claim 100.

The fourth object of the invention is achieved by an air distributor according to claim 135.

The spray gun of FIGS. 1 and 2 is a paint spray gun and has a

Pistol body 1 with a handle portion 2 and a head 3. These two sections 2 and 3 are as usual at an angle of about 100 degrees to each other. The grip area 2 has a compressed air connection 20 at its lower end. Through the handle portion 2 and through the head 3 extend from the compressed air port 20 from a plurality of air channels (which will be discussed later), which at the front end 8 of the head 3 of

Spray gun ends. The amount and pressure of the air passing through these air channels can be regulated in the usual way by means of an air micrometer 21. The front end 8 of the head 3 can still be equipped with an air nozzle, which may have projecting horns with openings (not shown). Of course, the spray gun can be equipped with other more or less usual designed air nozzle rings or the like, which will be discussed in more detail later.

The material to be sprayed is passed through the front end 8 of the head 3 of the spray gun. The front end 8 of the head 3 is closed when not operating the spray gun by a mechanism which will be discussed in more detail later. The mechanism is actuated by means of a so-called trigger guard 22; The amount of material can be regulated by a device, of which only one

Regulating screw 100 with locknut is shown.

In the present embodiment, the head 3 of the spray gun is designed in two parts. The head 3 has a rear end 3a, which is permanently connected to the handle portion 2 of the spray gun, and a front end 3b, which is mounted on a hinge 23 and folded away at the rear end 3a. In the present embodiment, the joint is designed as a rotary joint. The rotary joint 23 can be actuated by means of a control knob 24, which is shown in more detail in Figs. 4 and 4a. The adjusting knob 24 is a knob which is frusto-conical in the present embodiment. On its surface 24 a facing the operator, the button 24 is provided with an arrow 25. The arrow 25 indicates the state of the joint 23 and the hinged part 3b of the head 3 of the spray gun; in Fig. 4 the position "locked" is shown and in Fig. 4a the position "unlocked". The guidance of the material to be sprayed takes place in the spray gun according to the invention by means of a cartridge 4, of which an embodiment of FIGS. 3 and 3a is particularly well visible. The cartridge 4 is made of a low-cost plastic, in particular injection-molded. It has a first region 15, which is designed in the present embodiment as a hollow cylindrical tube. From this area 15 of the cartridge 4 is angled off in the present embodiment also as a hollow cylindrical tube 5 formed area, which can be connected for example with a reservoir for the material to be sprayed. The hollow cylindrical tube 5 serves as an inlet area for the paint or other flowable materials in the spray gun or in the cartridge 4. The reservoir could be a conventional gravity-fed gravity cup, a so-called "upside-down cup" or a bag or the like 5 indicates in the present

Embodiment at its free end on a raised mounting strap 16 for such cups.

The fastening tab 16 extends approximately over half of the circumference of the tube 5, is about half as high as this and has on its outer side a substantially cuboid connecting rail 16 a, a particularly simple, but secure fastening and a simple release of a cup with or without interposing an adapter of the spray gun allows, wherein the cup or the adapter has a channel 16 corresponding to the corresponding channel-shaped counter-element, which can be pushed into or over the connecting rail 16a. A connection over such projections is particularly safe, since the components are guided over a large length.

This fastening tab 16 or another tab arranged on the inlet tube 5 can in other cases also serve to support the cartridge 4 on the spray gun (compare FIGS. 8 to 10).

It is also possible to connect to the tube 5 a hose or the like, which optionally leads to a pump, a pressure vessel, a pressure cup or to another vessel. Suspension cup (suction cup) and so-called side cup can also serve as a reservoir; the tube 5 of the cartridge 4 only has to be aligned in another position. But it is also possible to produce the reservoir and the cartridge as a one-piece component.

Of course, the tube 5 may also be designed differently than previously described. The connecting rail 16a may be replaced by a gutter and a connecting rail may be provided on the reservoir or on an adapter, a hose or the like. On the other hand, instead of the connecting rail 16a, it can have a latching nose which enables a snap connection directly or indirectly via an adapter to the storage container or a hose or the like, it being understood that a latching hole corresponding to the latching nose, a latching groove or the like must be provided on the other component. Conversely, it is of course also possible to provide a locking hole or a locking groove on the tube 5 and a latching nose or the like on the other component. In another embodiment, the tube 5 a

Threaded having a full thread or a threaded segment, for example, extends by about 180 degrees. In particular, in the latter case, the assembly and disassembly of the cartridge and reservoir or material supply is easy to do manually by turning the components against each other. When using detents or thread segments results in a kind

Bayonet connection, which allows a particularly easy manual handling.

On the other hand, the tube 5 may have a plug-in connection, either from

Counter element of the reservoir is overlapped or engages in the counter element of the reservoir. In the latter case, it is particularly certain that no paint or other material emerges at the junction between the cartridge and the reservoir. A combination of rotary and plug connection is also possible.

Similarly, an intermediate adapter a plug, a

Have thread connection or the like.

A connection via brackets, pins or the like is also conceivable.

As can be understood from what is understood at least implicitly, the contour of the tube 5 does not necessarily have to be round as shown; it can also be oval, quadrangular, that is to say arbitrary; it only has to be matched to the contour of the connection to the reservoir and / or to the contour of the spray gun. Of course, the actual cartridge body, so the tube 15, not necessarily as shown in the figures to be cylindrical. A conical shape, a cuboid shape or any other geometric shape with or without

Cross-section change is also possible. The shape only has to be matched to the shape of the cartridge receptacle in the spray gun or vice versa. However, the cylindrical shape or a conical shape is advantageous both in the actual cartridge tube 15, as well as in the inlet tube 5, because there are no edges in the interior of the tubes, which could adversely affect the material flow. With a cylindrical tube 15 and a particularly good color needle guide is possible, which will be discussed later in more detail.

The cartridge 4 can be divided longitudinally or transversely, depending on the individual requirement. The two cartridge parts can be locked, glued,

welded or otherwise attached to each other.

By virtue of the first region 15 of the cartridge 4, which is designed essentially as a hollow cylindrical tube in the present exemplary embodiment, a guide channel 6 extends for the material to be sprayed, which terminates in an outlet region 7 which is arranged at the front end 8 of the head 3 of the spray gun. On the concrete design of the

Outlet area 7 will be discussed later. Around the hollow cylindrical tube 15 around a mounting plate 17 extends, which is simply attached to the tube 15 in the present embodiment. If necessary, the support of the disc 17 can be secured by adhesive on the cartridge 4 or achieved by welding. The mounting plate 17 may also have been injected in one piece with the cartridge 4. Through the mounting plate 17 and from the mounting plate 17 away, two hollow stub 17 a and 17 b, which emerge from the mounting plate 17 at the rear portion 3 a of the spray gun facing surface 17 c extend. The nozzle 17 a and 17 b are integral with the present embodiment in the present embodiment

Attachment plate 17 made.

In another embodiment, the nozzle could also be inserted into corresponding openings of the mounting plate, glued or otherwise attached.

The nozzles could be in another embodiment only through holes in the mounting plate. The nozzles 17a and 17b engage in a respective bore in the rear end 3a of the spray gun. In the present embodiment, the nozzles 17a and 17b are inserted into air channels of the spray gun. Each air duct is provided at its end facing the connection piece 17a or 17b with a sealing ring 17f or the like. The seals can also be arranged on the neck itself or the neck can be formed so that they themselves seal radially and / or axially. The connection between cartridge 4 and spray gun is thus airtight at this point. The nozzles 17a and 17b can accomplish the holding function for the cartridge 4 alone.

The fact that two stubs 17a and 17b are provided, the hold is particularly safe.

In another embodiment, one or more nozzles could also serve only for attachment of the cartridge to the spray gun and not also for air guidance. Of course, you do not need to be hollow. However, if the nozzles 17a and 17b are hollow as proposed and contribute to the air flow, this is of course particularly advantageous.

On its other surface 17d has the fixing plate 17 has a slotted guide 17e for receiving an air distributor 18, which may have a corresponding counter-backdrop (not shown). After sliding or after mounting on the tube 15 an excellent centering of the air distributor 18 is ensured on the cartridge 4. But it would also be possible to hold the air distributor 18 by other means such as locking lugs, rails or the like. The air distributor 18 and the cartridge 4 could also be glued to each other, welded together or be made in one piece or connected in accordance with the mounting plate 17 ..

The air distributor 18 according to the invention is in the present embodiment in

Essentially frusto-conical and has four areas 18a - 18d. The areas 18a -18d, as viewed in the injection direction, smaller. In the immediately adjacent to the mounting plate 17 largest diameter portion 18a and in the overlying smaller area 18b a plurality of circular air holes 18e are provided. The two subsequent areas 18c and 18d have no air holes. However, it is also possible to equip only one of the regions 18a to 18d or all regions 18a to 18d each with a single air hole, which may also be non-circular, for example slit-shaped. With the shown circular

Air holes 18e can achieve a uniform atomization of the material to be sprayed become. The air flow can preferably also be brought into the desired shape with a so-called air guide disk and / or other air guidance means.

In the uppermost region 18 d of the air distributor 18, a passage opening 18 f for a paint needle 19 is centrally provided, as will be discussed in more detail later.

The air distributor 18 according to the invention can of course be used separately in any other spray gun having a cartridge or not, due to its special design with advantage.

The cartridge 4 has at its free end a substantially frusto-conical tip 4a. In the above-described first tubular portion 15 of the cartridge 4 is in the material-carrying channel 6 in the present embodiment as a cylindrical paint needle 19 formed material-carrying member 9 held by the previously mentioned passage opening 18f in the air distributor 18 to the frusto-conical tip 4a of the cartridge 4 extends. The frusto-conical tip 4a of the cartridge 4 has a passage 4b for the first end 19a of the paint needle 19. The first end 19a of the paint needle 19 and the tip 4a of the cartridge 4 are in alignment. When the cartridge 4 is installed in the spray gun, the tip 4a of the cartridge 4 is located in the outlet portion 7 of the spray gun.

In another embodiment, not shown, the frusto-conical tip 4a may also have a cylindrical region in the front end region.

To reset the color needle 19 or to close the free end 4a of the cartridge 4 through the paint needle 19, a color needle spring 303 is provided in the rear head 3a. This color needle spring 303 may be disposed in the material flow adjustment device 100. A second part of the paint needle 19, on which the spring acts, is connected via a mechanism to the rear end of the paint needle, on which the driver 27 or the like is arranged. The paint needle 19 is connected via this and possibly another mechanism with the trigger guard 22.

The paint needle 19 penetrates with its second end 19 b, a cap 26, which closes the end of the cartridge 4 facing away from the outlet 7. In the present

Embodiment, the cap 26 is plugged as a separate component on the rear end of the tubular portion 15 of the cartridge 4 and lies with its circulating Edge 26 a outside of the tube 15 at. However, the cap 26 could also be formed as a plug or the like, which engages in the tube 15. Or simply as a lid, which rests on the tube 15. An attachment, whether positive or non-positive, with or without aids such as threads, latches, adhesive, welding or the like is possible.

The paint needle 19 is about 50% longer than the tubular, material-carrying region 6 of the cartridge 4 and is accordingly with its free end 19b in the longitudinal direction far beyond the cartridge 4 addition. The free end 19b also has an end 27 on a driver. Between the cap 26 and the driver 27, a return spring 28 may extend for the paint needle 19. The return spring 28 is supported on the one hand with a first end on the outside of the cap 26 and on the other hand with a second end on the inside of the driver 27 from. In the embodiment of FIG. 3, the return spring 28 is formed as a helical spring. However, it is possible to use another spring such as a leaf spring, a bellows or the like. To operate the paint needle 19, the trigger guard 22 could engage the outside of the driver 27, e.g. with a claw, or he could rest on the driver 27. Other types of attacks are also possible.

Also, a second paint needle could be coupled in the rear head portion 3a of the spray gun with the trigger guard 22 and in turn act on the paint needle 19 in the cartridge 4 or operate them

The return spring 28 may be a tension as well as a compression spring. In a particular embodiment, the paint needle is opened by the return spring 28 when the

Trigger guard 22 is pulled off and after releasing the trigger guard 22 is pressed by the return spring 28 in the forward position and the paint needle 19 closes the passage opening 4b.

In another embodiment, the paint needle could be brought by a tension spring in the closed position and withdrawn by means of connection of trigger guard to the paint needle by pressing the trigger guard and thereby the passage opening in the top of the cartridge are released.

It is also possible to provide the return spring within the cartridge 4. Such a return spring could be provided with a first end on the inside of the cap 26 or on a hook provided in the cartridge 4 or the like, and with a second one Support end, for example, on a provided on the paint needle 19 hook or the like.

Of course, functional seals can be provided on or in the cartridge 4, for example on its frustoconical tip 4a and / or on the passage opening 4b for the paint needle 19. Such a seal could be for example a molded sealing lip, a foil seal, a molded seal, a piercing membrane, a corrugated membrane, a bellows membrane or a sealing ring.

Also, the paint needle 19 could be equipped with such or similar functional seals. Or the paint needle 19 itself or the tip 19 a of the paint needle 19 could be made of a metallic or non-metallic material

Seal properties or be coated with a corresponding material having sealing properties.

In FIGS. 5 to 5b, a particularly advantageous embodiment of a

Return spring or actuating spring 28 shown. The spring 28a according to the invention is manufactured in one piece with the cap 26 of the cartridge 4. In the present embodiment, it consists of two curved, elastic, in view approximately W-shaped

Bow spring legs 28b and 28c. The ends of each "W ^'s" are connected to the surface of the cap 26, the center of the ^"W" s "is supported on a stopper 19c from which is provided to the ink needle 19, in a region of its free end 19 b, which is opposite to the driver 27. The stopper 19c is formed substantially as a frusto-conical projection and applies its larger circular area to the centers of the "W ^'s ." An arc spring leg 28b extends along one side and the other arc spring leg 29c along the other side of the color needle 19. In FIG. 5 a shows the position of the bow spring legs 28b and 28c in the unassembled state The bow spring legs 28b and 28c then abut against the outer face of the truncated cone 19c. When assembled, the bow spring legs 28b and 28c are snapped onto the base of the truncated cone 19c Easily stops when the paint needle 19 is pushed through the passage opening 26b in the cap 26. This enables a secure closing of the paint needle 19. Of course, it is also possible to have only one such curved spring part 28b or 28c or more than two curved spring parts 28b and 28c, but the embodiment shown is optimal Guidance, because only a few spring parts (only two) are provided, the symmetrical addition to the

Painted needle 19 run. Also, the stopper 19c could have a cylindrical or an opposing conical shape, another geometric shape, eg a disc or ring shape.

For additional safety, the passage opening 26b is equipped with a sealing lip 26c in the closure means of the cartridge 4 designed here as a cap 26. Instead of the sealing lip 26c, a foil seal, a piercing membrane, a corrugated membrane, a bellows membrane, a sealing ring, another seal, e.g. a molded seal, be provided. This also applies to all other possible

Embodiments of the closure means.

As shown in FIGS. 5a and 5b, the cap 26 has a stopper extension 26d. In the assembled state, the stopper extension 26 d fits snugly against the inner wall of the cylindrical tube 15.

In Fig. 5c, a variant is shown, in which the in Figs. 5 to 5b shown

multi-legged bow spring is replaced by two single-sided bow springs 28d.

In the variant of FIG. 5d, the actuating spring is designed as a helical spring 28e, which engages with its ends 28e 1 and 28e 2 in the cap 26 and which is supported with their turns 28e 3 at the base of the truncated cone 19c.

In Fig. 5e, the actuating or return spring 28f for the paint needle 19 is integrally formed on the cap 26. The spring 28f is designed here as a spring angle. The point of attack or the stopper of the spring 28f on the paint needle 19 is in the present

Embodiment formed as a circular disk-shaped projection 19d on the paint needle 19. The circular disc 28 f could also be made as a separate component and connected by gluing, welding or otherwise with the paint needle 19. Other forms than a semicircular disc or rectangular plates are also suitable as stoppers. Of course, the stopper could also here as in the previously described embodiments be frusto-conical or have almost any other geometric shape. From Fig. 5e is particularly well seen how the paint needle 19 passes through the tubular portion 15 of the cartridge 4 and how the inlet portion 5 may look like. In the embodiment shown here, the paint needle 19 has a recess 304 for attachment or delimitation of further components.

The cartridge 4 is inserted by hand into a receptacle which is provided in the front end 3 b of the head 3 of the spray gun, which will be described later in more detail. From Fig. 6 it can be seen that the trigger guard 22 of the spray gun near the driver 27 of the

Paint needle 19 engages with a first bearing pin 22a. In the present

Embodiment of FIG. 6, the bearing pin 22 a is held at both ends by a respective clip 200. The clips 200 have two substantially rectangular plates 201 a and 201 b, which are connected to each other via a film hinge 202. The platelets 201 a and 201 b engage around the trigger guard 22 at the two legs 22 a and 22 c. In this way, the secure position of the bearing pin 22 a for

Trigger guard 22 guaranteed. The connection between the bearing pin 22a and trigger guard 22 is always ensured due to the connection to the clips 200, If these and / or the bearing pin 22a were made of elastic material, the connection is particularly secure. Thus, on the one hand, the secure hold of the components to each other and on the other a soft pressing the trigger guard 22 with

constant operating force allows.

In another embodiment, not shown, the bearing pin 22a could also be made in one piece with the clips 200.

The bearing pin 22a preferably has the illustrated rectangular cross-section, but in other embodiments, not shown, may have any cross-sections, e.g. oval or round and / or he may have pockets, claws, hooks, etc. for carrying a paint needle, for example, the driver 27 of the paint needle 19. Other alternative forms of engagement and engagement are also possible.

Also other alternative forms of mounting the bearing pin on the trigger guard, such as e.g. Notches, holes, slots etc. are possible.

From Fig. 6 is also the second, conventional bearing pin 22d of the trigger guard 22 can be seen.

The trigger guard 22 and thus ultimately the paint needle 19 can be manually operated as usual by pressing and releasing. But it is also possible the trigger guard 22 and / or the paint needle 19 optionally additionally pneumatically, hydraulically, via magnetic fields, electrically or a combination thereof to operate.

Any additional type of actuation may be linear, rotational, by displacement of two or more surfaces (rotary valve, e.g., ball valve), rotating plus linear (e.g.

Thread drive be analog tap.

The above-described arrangement of cartridge 4 and optionally color needle 19 together with air distributor 18 by means of a coupling ring 10, in the present

Embodiment of the air distributor 8 and the cartridge 4 are inserted. The coupling ring 10 is preferably made of plastic and has at its the air distributor 18 side facing an approximately semicircular extension 1 1. The extension 1 1 is dimensionally matched to the circumferential dimension of the tubular inlet portion 5 of the cartridge 4. In the assembled state, the extension 1 1 fits snugly on the tube 5. Preferably, the extension 1 1 has elastic properties. It can be made in one piece with the coupling ring 10, but does not have to. It can also be clamped, clipped, glued or otherwise secured to the coupling ring 10, for example.

About 180 degrees offset from the extension 1 1 is a substantially

cuboid mounting block 29 on the coupling ring 10. In the assembled state, i. when the cartridge 4 is inserted into the front end 3b of the head 3 of the spray gun, the mounting block 29 engages in a correspondingly shaped receptacle 30 which is provided in the spray gun. In the present embodiment, the receptacle 30 is a slot (or a pocket), which is arranged in the rear end 3a of the spray gun.

The mounting block 29 is at its free end by a bearing axis 29 a

penetrated, the both sides protruding laterally from the mounting block 29. The mounting block 29 is displaceable with its bearing axis 29a along the receptacle 30 in the spray gun. Stops 30a and 30b limit the possible path of the bearing axis 29a in the receptacle 30th

In the present embodiment, the mounting block 29 has resilient properties. It can be made in one piece with the coupling ring 10, but does not have to. The mounting block can be constructed in one or more parts and, for example, can also be clamped, clipped, glued or otherwise secured to the coupling ring 10. The mounting block 29 may also be made of a rigid material

Of course, it is particularly advantageous for manufacturing reasons, if the entire coupling ring 10, i. the annulus with the extension 1 1 and the block 29 are made in one piece.

The mounting block 29 may of course be designed differently,

for example as a fastening ball, hinge, e.g. As a thin film hinge etc .. It is only essential that he secure attachment of the coupling ring 10 at the

Spray gun guaranteed. Both detachable and non-detachable connections are possible, depending on whether the coupling ring 10 should always remain on the spray gun or not.

For releasably connecting the two parts 3a and 3b of the head 3 or the coupling ring 10 to the other components hook, bayonet, locking lugs can be provided, which are arranged radially or axially.

Depending on the individual requirement, stops for limiting movement may also be provided here.

The locking or unlocking manually, pneumatically, magnetically, electrically, via friction forces, as well as via acceleration can be done automatically or manually

It is also possible that the coupling ring 10 is made in one piece with the air distributor 18 and / or with the cartridge 4.

On its outer surface 31 of the coupling ring 10 is provided with a thread 32. The thread 32 is designed in the present embodiment as a full thread. On the thread 32, an air nozzle directly or indirectly by means of a screw ring

be screwed on. The air nozzle can be made of steel, other metals or plastic.

Such an air nozzle can be designed as a round jet nozzle or provided with at least one horn for broad-jet shaping. In the horn then holes or Air outlet openings for beam shaping introduced. The holes or openings in the horn and / or the round jet bore (s) may also be non-cylindrical and have any cross-sections.

In another embodiment, it is possible that the air distributor is or can be connected directly or indirectly with at least one further air distribution means.

For example, a horn on the air distributor or force fit or be mounted, glued or welded or be.

The horn or other further air distribution means can also be made in one piece with the air distributor.

The shape of the cartridge receptacle in the spray gun must, as already mentioned, of course to the shape of the cartridge, if necessary, in addition to the previously described

Accessories coupling ring 10, air distributor 18 etc. be adapted or the

Cartridge shape, if necessary together with accessories (eg air distributor) must conform to the shape of the

Cartridge recording to be adjusted. ,

The individual or all components can be connected by friction, spring force or otherwise non-positively or positively with each other. If necessary, the components can be supported via abutments and / or other fasteners.

During operation of the spray gun according to the invention, the gripping region 2 and the head region 3b of the spray gun are in the "locked" state via the joint 23 (see FIGS. 1 and 4)

accomplished. In spray position of the gun, color from the not shown

Reservoir through the angled, tubular inlet portion 5 in the channel 6 of the cartridge 4, which leads the paint needle 19 and through this cartridge 4 through to the free end 4a, ie to the outlet 7, which arranged at the front end 8 of the head 3 of the spray gun is. Can be operated, the paint needle 19 by means of the trigger guard 22. Depending on its position, the paint needle 19 is either withdrawn; the outlet area 7 is then free and the spraying process can then take place or the paint needle 19 is advanced; the outlet area 7 is then closed and no injection process can take place. The amount of material, as already mentioned above an arranged in the spray gun device are regulated, of which only the adjustment screw 100 is shown here.

A proper guidance of the paint needle 19 is ensured in particular by the return spring 28 described above, which is supported on the one hand on the driver 27 of the paint needle 19 and on the other hand on the cap 26 of the cartridge 4. The desired spray pattern can by the special air flow through the openings 18 e in the air manifold 18 and possibly also attached to the spray gun, on the external thread 32 of the

Overwrfrings 10 attached air cap with horns, can be achieved. The amount and pressure of the air can be regulated by means of the air micrometer 21 described above.

After completion of the injection process, the knob 24 is rotated to the "unlocked" position (see Fig. 4a), whereby the areas 3a and 3b of the head 3 are pushed apart in the direction of the axis of the paint needle 19 and then can be folded away from each other by about 90 degrees so that the region 3b, which carries the cartridge 4, runs approximately parallel to the handle 2 of the spray gun (see Fig. 2) .The reservoir for the paint or other material to be sprayed can still be connected to the cartridge 4 or have already been removed from this.

When pushed apart, the bearing axis 29a of the mounting block 29 of the coupling ring 10 moves from the rear stop 30a of the receptacle 30 along the

Recording 30 to the front stop 30b of the receptacle 30. After turning the head portion 3b about the bearing axis 29a by about 90 degrees, the arrangement of coupling ring 10 and cartridge 4 together with air distributor 18 and the like so far from the spray gun that the cartridge 4 free is accessible .. The used and possibly with

Paint residues afflicted cartridge 4 can now together with the air distributor 18 and the

Return spring 28 or 28a easily pulled by hand from the coupling ring 10 in the front end 3b of the head 3, discarded and replaced by a new injection process by another, new, clean cartridge. A cleaning of the spray gun itself is possibly necessary in the area of the air nozzle, if available.

Characterized in that the cartridge 4 is sealed at both ends by the paint needle 19, and spray material in the combination of cartridge 4 and reservoir can be stored without this dries. The cartridge 4 can thus be used again without contamination of the spray gun again. If desired, the air distributor 18 can still be used one or more times, since it is not polluted at all.

Suitable plastics for the cartridges and one or all of the components described above are, for example, PE, PA, POM, peek, which may optionally be glass fiber reinforced.

The spray gun may be made of plastic or a metal such as steel, brass, aluminum, sintered metals, titanium or alloys thereof. The production of ceramic and other hard materials is also possible.

The cartridge can also be made of the same materials as the spray gun. Since the cartridge is then relatively valuable, it may possibly be used several times. The cleaning effort in the spray gun is also low here, since just the cartridge would need to be cleaned if you want to reuse it when changing the spray material.

In the embodiment shown in Fig. 7, the air distributor 18 is made in one piece with the coupling ring 10. The air distributor 18 has here, similar to the air distributor 18, which is particularly well visible from Fig. 3a, a plurality of regions 18a to 18d (same

Details are provided with the same reference numerals). The region 18a is formed on the outer surface 31 of the coupling ring 10. In this air distributor 18, the portions 18b and 18c have a few circular air holes 18e, but they may also have the number of air holes 18e shown in Fig. 3a, or other numbers of vents and vents.

The one-piece embodiment is particularly advantageous because none at all

Positioning of the air distributor 18 must be made to the coupling ring 10 ..

Also, this air distributor 18 has a slotted guide 17e, which at a

Fixing plate 17 is provided. The cartridge 4, which is the same here as the cartridge 4 shown in FIG. 3 a, can be inserted into the coupling ring 10. 4, the same elements and details as in the cartridge 4 of FIG. 3a are present in the cartridge 4. Same elements and details are the same

Provided with reference numerals. FIGS. 8 to 10 show a second spray gun according to the invention. As usual, the spray gun has a gun body 1 with a grip area 2 and a head 3. These two areas 2 and 3 extend as usual at an angle of about 100 degrees to each other. The grip area 2 has a compressed air connection 20 at its lower end. Through the grip area 2 and through the head 3, a plurality of air passages (which will be discussed in detail later) extend from the compressed air port 20 and terminate at the front end 8 of the head 3 of the spray gun. The amount and pressure of the air passing through these air channels can be regulated in the usual way by means of an air micrometer 21. The flow of material may be regulated by means of which only one adjusting screw 100 and one adjusting knob 101 are shown.

The head 3 here has no parts hinged against each other. In another

However, the head could also have parts which can be folded away from one another.

The front end 8 of the head 3 is equipped with a conventional conventionally designed air nozzle 33, which has two projecting horns 33a, 33b with openings 33c in the facing surfaces. The air nozzle 33 is secured by means of a likewise known per se air nozzle ring 13 on the spray gun, on the cartridge 4. The cartridge 4 has (as the cartridges from the figures described above) for this purpose a coupling ring 10 which in the present

Embodiment at the free end 4a of the cartridge 4 is molded. At his

Outer surface 31, the coupling ring 10 has a thread 32, is screwed to the present invention, the air nozzle ring 13 with its internal thread. The air nozzle ring 13 extends almost as far as the inlet region 5 of the cartridge 4.

The cartridge 4 according to FIGS. 8 to 10 also has a tubular inlet region 5 with a lug 16. The lug 16 also extends here about half of the

Circumference of the tube 5, is about half as high as this, but has no connecting rail as the mounting strap of Fig. 3a. That is not necessary, because at the

Embodiment according to FIGS. 8 to 10, the tab 16 does not serve as a fastening tab for the material reservoir or the like. Such a member may be connected to the cartridge 4 by engagement with the tubular inlet portion 5 with a projection 16c on the inside of the tab for engagement with a counter projection or the like. The cartridge 4 is partially supported by the tab 16 on the head 3 of the spray gun. In the special case shown here, the tab 16 rests with its outer surface on the correspondingly shaped outer surface of the hook 36 of the spray gun.

On the other hand, a latching hook 37 is provided on both sides of the cartridge 4 according to FIGS. 9 and 10, which is integrally formed on the tubular area 15 of the cartridge 4 via a film hinge 37a. Each latching hook 37 is laterally deflectable via its film hinge 37a. The latching hooks 37 are used for releasably securing the cartridge 4 on the head 3 of the spray gun, which has corresponding to the shape of the latching hooks 37 designed slots 38 in its two side walls. In the exemplary embodiment according to FIGS. 8 to 10, the latching hooks 37 are essentially triangular in plan view and each have a barb 37 b on a tip facing away from the film hinge 37 a. The locking hooks 37 are about as long as the coupling ring 10 is high. Such relatively long latching hooks 37 are easily manually operated.

The slots 38 in the spray gun can also be configured as holes or simple recesses or the like.

During operation of the spray gun, a portion of the latching hooks 37 extends into the side slots 38 of the spray gun and another portion of the latching hooks 37 outside (see Fig. 8). After use of the spray gun, when the air nozzle ring 13 is unscrewed, pressure 37 can be exerted in the direction of arrow 301 of FIG. 10 on the latching hook 37 on the outboard portion of the locking hooks, so that the

Swing latch hook in the direction of arrow 302 of FIG. 9 to the outside. The cartridge 4 can be touched on the coupling ring 10, withdrawn in the spray jet direction 300 from the head 3 of the spray gun and discarded.

The cartridge 4 is thus on the one hand by means of the coupling ring 10, the latching hook 37 and on the other hand by means of the air nozzle ring 13 on the spray gun very safe, but easily detachably attached as needed.

In the fully screwed state, the air nozzle ring 13 presses against the surface 37c of the latching hooks 37 described above. The barbs 37b of the latching hooks 37 are thereby pressed against the gun head 3, resulting in a secure hold of the coupling ring 10 on the spray gun. The cartridge 4 therefore can not move back and forth either in the spray jet direction 300 or laterally in the spray gun. That way, one becomes guaranteed at any time, but easily removable after use attachment of the cartridge 4 to the spray gun.

However, a similarly secure hold can also be achieved with an air nozzle ring which does not extend as far as the inlet region 5 of the cartridge 4, as in the present exemplary embodiment.

In another embodiment, not shown, the latching hooks 37 and the film hinge 37a can be made so stiff or designed so that the additional securing of the latching hooks 37 through the air nozzle ring 13 is not necessary and the latching hooks 37 nevertheless securely engage the gun head 3, without affecting the solubility of this.

In another possible embodiment, the air nozzle is fixed with or without integrated air distributor directly on the spray gun or with the cartridge without a coupling ring.

In Figs. 11 and 12, the cartridge 4 is provided with the coil spring 28e of Fig. 5d. (Same details are provided with the same reference numerals). The tubular region 15 of the cartridge 4 is also equipped with a fastening disk 17 already described in greater detail with reference to FIG. 3a. In Fig. 12 it can be seen that the cartridge 4 is provided at its tubular portion 15 with a circumferential locking ring 15 a or the like for the mounting plate 17. The attachment plate 17 here has a bushing 17d, through which the cartridge 4 extends. On the socket 17 d a special air distributor 18 is attached. The air distributor 18 is closed at its front end with a wall 18 a, which has a passage opening 18 f for the cartridge 4 in the center. In addition, the wall 18a is provided with several air holes 18e. This is very advantageous for achieving a good, uniform spray pattern with desired atomization.

In particular, in Fig. 1 1 it is shown that the mounting plate 17 and the

Air distributor 18 may have (further) positioning aid 12 at its rear side.

In the embodiment of FIGS. 13 and 14, the air distributor 18 as well as the one shown in FIGS. 1 and 12 is formed and fixed to the cartridge 4, by means of a specially designed coupling ring 10. The coupling ring 10 is here cylindrically shaped and centrally equipped with an insert 10a, which is made in one piece with the coupling ring 10, but could also be attached in other ways, such as glued. The insert 10 a is provided with a passage opening 10 b for the tubular portion 15 of the cartridge 4. In the front region of the coupling ring 10, an air distributor 18 is used, which is the same as the air distributor according to FIGS. 1 1 and 12 formed, but could also be designed differently. In the present embodiment, not the cartridge 4 (as in the embodiment of FIGS. 9 and 10), but the coupling ring 10 on both sides each have a latching hook 37. Each latching hook 37 is integrally formed on a film hinge 37 a on the inside of the

Coupling ring 10 molded. The latching hooks 37 are laterally deflectable via the film hinges 37a. The latching hooks 37 are used for releasably securing the coupling ring 10 together with the cartridge 4 and the air distributor 18 at the head 3 of the spray gun, which has corresponding to the shape of the latching hooks 37 designed slots 38, holes, other depressions, etc. in its two side walls (see. Fig. 9).

In the fully screwed state of the air nozzle ring, not shown here presses against the surface 37 c of the previously described, here arranged on the coupling ring 10 latching hook 37. The barbs 37 b of the latching hooks 37 are thereby pressed against the gun head 3, resulting in a secure hold of the coupling ring 10 on the Spray gun yields. The cartridge 4 therefore can not move back and forth either in the spray jet direction 300 or laterally in the spray gun. In this way, an always secure, but easily removable after use attachment of the cartridge 4 is ensured on the spray gun.

In another, not shown embodiment, the locking hooks 37 and the film hinge 37a can be made so stiff here or designed so that the additional securing of the latching hooks 37 through the air nozzle ring is not necessary and the

Nevertheless, snap hooks 37 securely engage in the gun head, without affecting the solubility of this.

The third spray gun according to the invention shown in FIGS. 15 and 16 corresponds in many parts to the spray gun shown in FIG. 8. So it has a gun body 1 with a handle portion 2 and a head 3. These two sections 2 and 3 are at an angle of about 100 degrees to each other. The grip area 2 has a compressed air connection 20 at its lower end. Through the grip region 2 and through the head 3, a plurality of air channels extend from the compressed-air connection 20 and terminate at the front end 8 of the head 3 of the spray gun. The amount and pressure of these air channels flowing air can be regulated in the usual way by means of an air micrometer 21. The material flow can be regulated by means not shown in detail, of which a regulating screw 100 and a knob 101 are shown here.

The head 3 in the spray gun according to FIGS. 15 and 16 has no parts which can be folded against one another, but could also have hinged parts.

The front end 8 of the head 3 is here also equipped with a conventional, conventionally designed air nozzle 33, which has two projecting horns 33a, 33b in the spray direction with openings 33c in the facing surfaces. The air nozzle 33 is attached to the spray gun by means of a likewise known air nozzle ring 13, similar to the embodiment of FIG. 8.

The cartridge 4 according to FIGS. 15 and 16 substantially corresponds to the cartridge 4 shown in FIGS. 11 and 12. The cartridge 4 has an angled, tubular inlet region 5 for a material-carrying channel 6 which ends in an outlet region 7 which is arranged at the front end 8 of the head 3 of the spray gun. When

Material leading component 9 is also a paint needle 19 is provided here. The tubular inlet portion 5 is provided with a tab 16. The tab 16 extends over about half the circumference of the tube 5, is about half as high as this. The cartridge 4 can be supported on the tab 16 on the head 3 of the spray gun; the tab 16 rests with its outer surface on the correspondingly shaped outer surface of the hook 36 of the spray gun.

The tab 16 is used in the present embodiment for attachment to the

Reservoir for the material to be sprayed.

The cartridge 4 is equipped with an air distributor 18, which is closed at its front end with a wall 18 a, which is provided with a plurality of air holes 18 e. The air distributor 18 is made here in one piece with the cartridge 4; the e.g. With reference to FIG. 12 described mounting plate 17 or the like can therefore be omitted here. In addition, the described with reference to FIGS. 3a and 3b, two nozzles 17a and 17b on

Air distributor 18 is provided (from Fig. 16, only one piece 17a can be seen). But it could also be just a nozzle, several nozzles, other nozzles or the like, and nozzles be provided in another arrangement for guiding the air at the air distributor 18 of FIG. 16.

As Fig. 16 further shows, the cartridge 4 with the nozzle 17 in the air channels of

Be plugged spray gun. Sealing rings or the like can

of course also be provided here. The head 3 has for this purpose at its end 3b in a conventional manner, an external thread 3c for releasably securing the known air nozzle ring 13, which on its internal thread 13a on the

Spray gun is screwed on. The air nozzle ring 13 extends almost to the

Inlet area 5 of the cartridge 4. This ensures that the cartridge 4 can not undesirably move back and forth in the spray gun.

The cartridge 4 is thus very safe mainly by means of the air nozzle ring 13 on the spray gun, but easily detachably attached as needed.

In another embodiment, the air nozzle inner surface rests against the front of the cartridge or parts thereof (e.g., the air manifold) and is fixed by the air nozzle ring after it is screwed into the gun as well as the cartridge.

In other embodiments, the support of the cartridge against the

Spray direction against the gun head 3 by means of the mounting plate 17, the cap 26, the tubular inlet 5, a stop on the first cartridge area 15 or a combination thereof.

In all embodiments, releasable connections between a

Overlock ring 10 and the spray gun described. There are, however

Embodiments possible in which a coupling ring is permanently connected to the spray gun. This would be particularly advantageous in the case of a multifunctional coupling ring, which is the same or similar to, for example, the coupling ring 10 shown in FIG. 3a or 14, for the spray gun operation. The cartridge 4 or another insert, which could be advantageously designed as a film, bag or the like, can also be safely, but releasably connected to the spray gun by such a non-releasably connected to the spray gun coupling ring. In all embodiments, the air nozzle 33 could also be integral with the

Air nozzle ring 13 to be executed.

The air nozzle ring 13 together with or without air nozzle 33 could instead of screwed snapped onto a fastener, be connected by quick connector, bayonet or other fasteners with the spray gun.

Finally, it should be pointed out that other material-carrying components 9 than the illustrated color needles 19 and / or cartridges 4 without material-carrying components 9 fall under the invention. Likewise, elements of the invention are readily applicable to other than with the spray gun types shown and described with or without hinged head with advantage.

In addition, of course, the details shown and described may be wholly or partially combined in any meaningful way, or omitted in whole or in part.
