Abstract

The invention relates to an adapter kit for foam guns for the discharge of hard foams for the filling of cavities in buildings and in the expansion. The object of the invention is the development of an adapter kit that zulaeszt the use of a foam gun for different product carriers. According to the invention, the adapter kit consists of a molded part or a plate with sleeve and sealing disc, which is screwed by means of an intermediate piece in the flow channel of a foam gun. On the intermediate piece of a bell can be screwed, in the slotted edge area aerosol can be attached, or by means of union nut a Schlauchanschluszstueck is screwed, for the Anschlusz portable aerosol container via an intermediate hose.

Field of application of the invention

The invention relates to a variable adapter kit for foam guns for the discharge of hard foam aerosol cans and portable aerosol containers for filling cavities in new construction and reconstruction of structural shelves and other finishing work.

Explanation of the essence of the invention

For discharging hardenable mounting foam on construction sites and in the finishing work and for filling other cavities are a variety of hand foam guns with attachable aerosol cans known, and foam guns that are connected by means of intermediate hose to portable aerosol container.

The disadvantage here has the effect that for the application of aerosol cans and containers of different manufacturers always a separate foam gun is to be used, which is adapted in each case via an adapter to the dimensions of the product packages to be used. Such adapters are mainly as part of the aerosol can disposable adapter, so that an increased consumption of material occurs. When using portable aerosol container of the required intermediate hose is firmly connected to the foam gun, so that no change can be made in this design for the use of aerosol cans, so that always different types of foam guns are required for different applications, so often to avoid complex equipment change unsuitable foams are used.

Object of the invention

The aim of the invention is the development of an adapter kit, which can be installed in known foam guns and without much effort, the use of various aerosol cans and containersfor a spray gun for discharging rigid foams, so that replacement of the spray gun when changing the product carrier is omitted.

Explanation of the essence of the invention The invention has for its object to develop an adapter kit for spray guns, by means of uniform Basic elements the use of different aerosol cans, as well as other aerosol containers for the discharge of Hard foams permitting. According to the invention the object has been achieved in that in the flow channel of a spray gun, a molding or a plate with Sleeve and sealing washer is screwed by means of intermediate piece. The adapter has both an internal thread and

an external thread and receives in an incorporated collar an additional sealing ring. On the external thread of the

Intermediate piece is a replaceable bell according to the dimensions of the aufzusetzenden aerosol can

can be screwed, in whose multiple slotted edge area the collar of the valve carrier of the aerosol can is pressed in and can be locked by means of a strap.

It is within the meaning of the invention that when using the spray gun for portable aerosol container instead of the bell means Union nut a hose fitting is used, which with an additional check valve, consisting of Ball and spring, is equipped. At this hose fitting is on known fittings, or an intermediate hose an aerosol container

connected.

The invention will be explained below with reference to an exemplary embodiment. In the accompanying drawings show

1: Half section for aerosol can (Var.1) hfcj.2: Half section for aerosol can (Var 2) Fig. 3: Half section for intermediate hose connection

In the flow channel 1 of a foam gun 2, a molded part 3 or a plate 4 with sleeve 19 and sealing washer δ is screwed by means of intermediate piece 6. In an incorporated collar 7, an additional sealing ring 8 is inserted and according to the dimensions of the valve carrier 9 of the aerosol can 10, a bell 11 screwed onto the external thread of the intermediate piece 6. The bell 11 is slotted several times in its edge region 12, in which the collar of the valve carrier 9 can be pressed and locked by means of clamping band 13.

After pressing the valve carrier 9 in the edge region 12 and screwing the bell 11 on the intermediate piece and locking with the clamping band 13 of the valve carrier 9 is sealed by the sealing ring 8 or collar 7 in the intermediate piece 6 and the valve 20 of the aerosol can 10 through the sleeve 19 or the molded part 3 is opened so that the foaming agent is present in the flow channel 1 and the foam gun 2 is ready for use until the aerosol can 10 is emptied. When using portable aerosol container instead of the bell 11 by means of union nut 14 a hose fitting 15 is visible, which is equipped with an additional check valve consisting of ball 16 and spring 17. At this hose fitting 15 is connected via a known intermediate hose or fitting 18, a portable aerosol container, which has a separate container valve. In this case, the check valve 16/17 causes an exclusion of outside air between the flow channel 1 and fitting 18, so that no curing of the foaming agent can take place in the terminal compartment. The advantage of the invention is that with a few simple steps an immediate conversion of only one foam gun for different aerosol cans or a hose fitting the use of portable aerosol container is possible. At the same time, the use of disposable adapters as a component of various aerosol cans as well as the replacement of foam guns for changing product carriers is eliminated.
