Description
Short designation: Device for connecting a aerosol can with filling mass with a spray nozzle stool via a connecting organ for the rocking thus connecting the spray- can holder with the spray gun that the spray can with its nozzle always hangs down DESCRIPTION The invention relates to a device for the connecting an aerosol can to filling mass, as in the ad- without polyurethane foam or any other filling or insulation material, 15 with a spray gun connectable to that spray can. As Figure 1 illustrates, it is of general knowledge to a canister of filling compound with its filling compound discharge opening to connect to the filling mass inlet opening of a spray nozzle 20 stool, located at the top of that spray gun. Through- that the spray can is upside down, i.e. with its outlet opening is applied downwards on the spray gun, the filling mass due to its weight in the direction of the spray nozzle move the stool, at least as long as, during use, the 25 position of the spray gun that allows. However, if the spray gun during work at elevated locations far away deviates from its vertical operating position, the throughput of filler mass stagnates from the aerosol can to the spray gun and will have to be - where possible - from a (different) standpoint 30 dents worked, whereby the supply of filling compound to the sprayer The pistol is being repaired. Apart from the filling mass throughput problem resulting from the position of the spray gun and the one connected to it aerosol can, a second problem arises in practice for, namely that of the (length of) the (far) above the 5 spray gun excellent spray can. Because the spray can is so protrudes far upwards, becomes, for example, the working in small spaces and in corners etc. hampered by the space occupied by the spray can in combination with the spray pi- stool. The present invention aims to provide a solution to offer a single solution for both problems indicated above. To that end, according to the invention, provision is made for a device 15 sealing for connecting an aerosol can to filling compound, such- in particular polyurethane foam or another filling or insulation material tie-up material, with a spray gun connectable to that spray can. stool, which fixture comprises - a spray can holder, designed for holding or be- 20 drums of the spray can and equipped with a connecting or- go that is designed for connecting the in such a way spray can holder with the spray gun that the spray can during use of the spray gun sufficiently free in relation to The spray gun can move, in particular rotate. 25 and / or swinging / rocking, so that the spray can runs through his center of gravity always with its filling mass outlet opening towards hangs below; - a connecting channel between the filling mass outlet opening of the spray can and a filling compound inlet connection of the 30 spray gun. The connecting channel can, for example, be formed by a flexible hose with a coupling at one end or connection cassette that fits the filling compound outlet opening of the spray can and with its other end a coupling or connection cassette that fits the filling compound inlet opening of the spray gun. The connecting channel can, however, be 5 example also via a different type of flexible and / or rotating bare coupling connected to the spray gun. These measures ensure that the spray can increasingly with its outlet opening hanging downwards, independent 10 of the position of the spray gun, whereby the filling mass constantly by his own weight in the direction of his out- flows through the feed opening. Except that this causes the throughput of the filling mass is secured, is thereby also achieved that the spray can is used completely empty, which in the 15 practice is not the case when using fixed with the spray gun coupled spray cans, as is currently the case is (see figure 1a). Furthermore, the measures according to the invention are 20 extends significantly less outwards (bo- protrudes and therefore "gets in the way", in particular in small workspaces, corners, etc. The spray can holder can be mounted on a "not easily detachable" 25 way connected to the spray gun, for example by means of a fixing pin through a in the injection mold pistol mounting hole (see figure lb), or can be connected to the spray gun via one of the spray gun (indeed) easily detachable, for example by 30 clamping device, connecting organ (see figure 1d). The present invention is not limited only to the in- direction as indicated above, but includes to- even any spray gun that is (already) equipped with a third similar design according to the invention, or that (already, specific) is prepared for non- easily detachable fasteners connection with a device according to the invention. The invention will now be discussed in more detail on the basis of of the figure description below. Figure la shows an illustration of a standard spray gun with matching full- spray can according to the current state of the art; Figure lb shows, in two views, schematically a standard spray can, equipped with a first example of an execution of a spray can holder of; Figure lc shows a spray gun, a spray can and, schematic, a first implementation proposal image of a complete interior according to the invention, executed with a flexible connecting hose; Figure ld schematically shows a standard spray can, equipped with a second version front- image of a spray can holder; Figure 1 shows a spray gun, a spray can and, schematic, a second implementation proposal image of a complete interior according to the invention, executed with a high-speed head peeling. Figure 2 shows an example of the execution of a spray can holder of an establishment according to the invention; Figure 3 shows an example of the implementation of a ver- binding organ with which the device fully due to the invention easily detachable on the handle of a spray gun can be- the clamped; Figures 4a and b schematically show an example of implementation. of a connection cassette that fits the filling mass outlet opening of an aerosol can, respectively of a connection cassette that fits the filling mass inlet opening of a syringe stool. Figure 1a shows an illustration of a standard syringe. 20 stool 1 with matching spray can 2 according to the current status of the technique. The spray can 2 is with its filling mass- outlet opening 2a at / in the filling mass inlet opening la of the spray gun 1 connected, usually by means of a type of bayonet coupling. Figure lb schematically shows a standard spray can 2, for- seeing a first example of the execution of a spray can- holder 3, drawn in two views. In its working position. hangs spray can 2 with its outlet opening 2a downwards- 30 den. Figure lc shows, in front and rear view, a syringe- stool 1, a spray can 2 and, schematically, a first execution ring example of a complete interior design according to the invention, for connecting a spray can 2 with filling mast- sa, such as in particular polyurethane foam or another filling or insulation material, connectable with that spray can 2 5 spray gun 1, which device comprises a spray can holder 3, designed for holding or containing the syringe- bus 2 and equipped with a connecting device 4 that is inserted- direct 3 for connecting the spray can holder in such a way with spray gun 1 - in the version shown in Figure 1 10 rings with a handle lb thereof - that the spray can 2 during use of the spray gun 1 in such a way that it is clear of the opening view of the spray gun can move, in particular rotating and / or swinging or rocking (see arrows 5), that the spray can 2 - by "eccentric" placement (i.e. bene- 15 the center of gravity of the combination of spray can 2 and spray can holder 3) of the one connected by the connecting element 4 formed a pivot point - due to its center of gravity always with its filling mass outlet opening 2a hangs downwards. 20 As is clearly visible in figure lc (see horizontal dot- peel line), the top of the (inverted) spray can protrudes 2 not or barely above the top of the syringe stool 1 out, which is a major advantage compared to the state of the art, in which the (inverted) spray can with 25 extends its full length above the spray gun. Furthermore, the setup includes a flexible hose 6 with one end of its a coupling 6a that fits onto the filling compound- outlet opening 2a of the spray can 2 and with its other outlet 30 end of a coupling 6b that fits onto the filling compound- inlet opening 1 of the spray gun 1. In the execution of figures lb and lc, the spray can holder is the 3 not easily detachable ("non-clickable") with (the handle lb of) the spray gun 1, for example by by means of a fixing pin 4a through an in (the handle 5 lb of) the spray gun 1 applied mounting open- ning. Figure ld schematically shows a standard spray can 2, for- seeing a second execution example of a spray can- 10 holder 3 which is connected to the spray gun 1 via a of (the handle lb of) the spray gun 1 easily detachable removable, for example by means of clamping ("clicka- ble"), connecting organ 7. 15 Figure 1 shows a spray gun, a spray can and, schematically, a second example of execution of a complete installation in accordance with the invention, executed with a shortcut 4b between the (flexible or non-flexible) connecting channel 6 and the spray gun 1. The 20 connection channel 6 can in this version either inside or outside (the housing of) the spray can holder 3 extend. The 4b quick coupler makes in this version part of the aforementioned liaison body 4, with which the spray can holder 3 (rotatable) with the 25 spray gun 1 is connected; the quick connector serves in this version therefore for both mechanical coupling and for (filler) fluid coupling. Can be used as a coupling made of a generally known type of pneumatic or hydraulic quick coupler, possibly slightly modified for 30 the present objective. Figure 2 shows an example of the execution of a spray can- holder of an apparatus according to the invention. Figure 3 shows an implementation example of a connection. device with which the device according to the invention easily detachable from the handle of a spray gun 5 can be clamped. Figures 4a and b schematically show an example of implementation. of a 6a connection cassette that fits the filling compound- outlet opening 2a of a spray can 2, respectively of a connection 10 closing cassette 6b that fits the filling compound inlet opening la of a spray gun 1. Thus, the present invention becomes a solution offered for both problems indicated above. Above- 15 it appears in practice that, by application of a arrangement according to the present invention is possible to get the filler from the spray can deeper into seams and joints etc. to inject. 20 Patent document GB2446785A shows a configuration where a disposable spray can is connected by means of an adapter and with a spray gun. By adding from an external source The fed compressed air pushes the foam towards the nozzle of the spray gun is fed. The spray can is fed by means of 25 an aerosol can holder and a connecting device with the spray- gun connected, with the spray can holder underneath. different angles, adjustable by the user, against The spray gun is secured by means of a fixed setting nut (11 or 17) which forms part of the connection 30 governing body. In GB2446785A it is not proposed or suggested- prepared to ensure that the spray can during use clear of the spray gun relative to the spray gun can move (5), in particular rotate freely, swing or rocking, causing the spray can to always hangs with its filling mass outlet opening facing downwards. Because the spray can – due to "eccentric" placement (i.e. below the center of gravity of the combination of spray can and 5 spray can holder) of the part formed by the connecting element pivot point - always with its filling mass due to its center of gravity if the outlet opening hangs downwards, the spray can will therefore already- time can flow completely empty without the user must be active in that himself 10 never get in the way when applying foam in bo- adjacent seams and corners. Additionally, regarding the invention or its preferred version, linings, it should also be noted that those in particular be- 15 draw has on a pressing facility for the connection of an aerosol can with filling mass, such as in particular a canister of PU foam or other under (permanent) pressure filling or insulation material, in combination with a spray gun stool. As figures 3 and ld illustrate, the clamp- 20 conjugate constructions suitable for both left-handed and right-handed use helpful. Regarding the aforementioned patent specification GB2446785A, it can be argued- It should also be noted that when using the resulting 25 known configuration an (external) air compressor is necessary, whereby the spray gun cannot freely roads (rotating, swaying) relative to the (in practice ticking fairly stiff) high-pressure hose ("air hose"). The The configuration of GB2446785A is therefore documented as 30 a spray glue tool, whereby an adhesive liquid is passed through by means of air compression - by an external, electric compressor, via the aforementioned air hose - is mixed at the end of the glue gun. Due to the stiff, inflexible air hose connection between the compressor and the gun, and furthermore because of the locking connection screw with the glue bushing connection, such as documented in Figure 2 (see section 11), among others. 5 of GB2446785A, is this construction impractical in practice able during necessary continuous (adhesive) work today. Interim unscrewing of the fastening connection thing (as suggested in the written opinion) will in the practice be too complicated during work activities and 10 is therefore not proposed or suggested in GB2446785A reard. The present finding therefore differs substantially. of the configuration from patent GB2446785A on many practic- specific areas of use or possibilities.

The spray can holder includes a connecting device (“bracket” 14) for connecting to the spray can holder with the spray gun such that it can rotate during use and is secured and a pivot point (“pivot” 13). In short, claim 1 of the present application differs from D1 in the characteristic that the spray can during use can move freely in such a way that the spray can, due to its center of gravity, always with its mass output opening hangs downwards. This is not explicitly mentioned in D1. The present claim 1 is therefore deemed new. Claims 2 through 8 are dependent. and conclusion 1 is also new. It is common knowledge that aerosol cans as referred to in the present application are intended to work when the filling mass outlet opening is directed downwards or only at a limited angle
