Definitions

  • the invention relates to a hand-held fire extinguisher with a housing for holding an extinguishing agent container, which has the basic shape of an upright disc with crowned outer sides and which consists of two half-shells which are essentially mirror images of one another, flat-domed and with their convex sides facing outwards, along their sides essential circular edge are joined together.
  • Such a hand-held fire extinguisher is known from German utility model DE 94 15 691.3 U1, where it is stated that the housing either forms the extinguishing agent container itself or can accommodate it. Since fire extinguishers put the extinguishing agent in the extinguishing agent container under considerable pressure so that it can be discharged, these extinguishing agent containers must meet considerable safety requirements, particularly with regard to the pressure resistance. For manufacturing reasons, an extinguishing agent container separately inserted into the housing is therefore primarily considered, as it corresponds to the above generic features of the invention, the disk-shaped housing with its convex outer sides specifying the upright basic position of such a hand-held fire extinguisher.
  • the invention has for its object to design the extinguishing agent container in a hand-held fire extinguisher of the generic type in such a way that it optimally uses the available interior space of the housing and can be easily adapted to the safety requirements.
  • extinguishing agent container is arranged coaxially with the interior largely being filled in the housing and has two mirror-inverted dished ends which are arched flat and which have cylinder jacket sections formed along their circumference, over which they are firmly and tightly connected.
  • the extinguishing agent container is constructed in mirror image, which is associated with manufacturing advantages.
  • the dished ends of the extinguishing agent container which lie opposite one another, adapt particularly well to the spherical shape of the housing with their convexly rounded outer sides.
  • the dished ends can nestle with their outer sides almost equidistantly against the walls of the half-shells of the housing, while for the rest along the periphery of the extinguishing agent container, So in the circumferential direction from the assembled cylinder jacket sections towards the joined edges of the housing half-shells, space for fittings or the like can be kept free because there is only a small interior volume available in the gusset of the edge area of the spherical half-shells of the housing converging here.
  • the half-shells on their inner sides advantageously have support webs which encompass the extinguishing agent container in the transition region between its clapper bottoms and cylinder jacket sections and have receiving contours correspondingly adapted to this transition region.
  • the extinguishing agent container has an opening which is arranged in the region of the assembled cylinder jacket sections. At this opening an outwardly projecting nozzle is attached, which is surrounded by web approaches, which are arranged on the inside of the half-shells, a valve fitting being attached to the nozzle.
  • the valve fitting is arranged in a space-saving manner in the narrow gusset space of the half-shells that converge at the edges, and on the other hand, a securing of the position of the extinguishing agent container, which is secured against axial twisting or pivoting, is achieved via the web approaches of the half-shells encompassing the connecting piece.
  • the nozzle of the extinguishing agent container is arranged to the side or laterally downwards and the valve fitting has an approximately tangential or circumferential direction of the joined edges of the half-shells, which emerges from the half-shells in the edge region.
  • a hose for discharging the extinguishing agent can be connected to the hose attachment piece and can be held without kinks under constant bending along the periphery of the housing.
  • the half-shells have a hollow contour along their joined edges for receiving the hose, the hose attachment piece entering this hollow contour at the point of exit from the housing.
  • An extinguishing gun is arranged in the usual way at the end of the hose for discharging the extinguishing agent.
  • an outwardly open trough is formed on the circumferential side opposite the hose attachment piece of the valve fitting on the extinguishing agent container, into which the hollow contour for the hose runs out along the periphery of the housing.
  • protruding clamping or latching webs are formed on the half-shells.
  • a hammer button is used to trigger the valve fitting, the axis of which is arranged radially to the extinguishing agent container or coaxially with its opening.
  • this button protrudes outwards by it passes through a corresponding opening in the edge region of the half-shells.
  • the striking button is covered by a fuse housing which can be pulled off the housing and which is secured to the housing by means of a seal which is made of environmentally neutral plastic.
  • a test manometer connection can be provided on the valve fitting to check the operational readiness of the device, a corresponding access opening then being formed in the adjacent half-shell of the housing. So the housing of the device does not have to be opened for the test process.
  • a riser pipe connects to the valve fitting, which should extend to the lowest point of the extinguishing agent container in the normal position of use. If the valve fitting is arranged on the side of the extinguishing agent container, the riser pipe must therefore be curved or angled. So that it can align itself with the lowest point of the extinguishing agent container, regardless of the screw connection of the valve fitting, the riser pipe is connected to the valve fitting by means of a loose swivel bearing.
  • Additional storage spaces can be created on the new hand-held fire extinguisher, for which purpose a hollow base can be formed on the underside of the housing below the extinguishing agent container, which base is also expediently provided in two opposite halves in the respective one Half-shell is integrated.
  • the storage space of the hollow base can be made accessible via a bottom flap, to which holders for smoke masks or the like can be molded.
  • the storage space can also be used to accommodate a fire blanket, a first aid kit or the like.
  • an insertion device for an identity card can be provided on the base of the housing, on which the respective erasure data is stored.
  • At least one of the half-shells of the housing has a labeling field which is curved only in one direction for attaching the adhesive label bearing the labeling. This is because a label that is flat in the starting position can easily be laid along a uniaxial curvature.
  • the housing 1 and 2 show a housing 1 which is assembled from two half-shells 2 and 3.
  • the housing 1 has essentially the shape of an upright circular disk with a certain thickness in the axial direction, the two outer sides of this disk being convexly bulging outwards, ie having a spherical shape. In the normal position of rest and use, the housing 1 is arranged upright, so that the diameter plane 4 lies approximately in a vertical plane.
  • the two half-shells 2 and 3 of the housing 1 are essentially designed and arranged in mirror image to one another, which is why the inner configuration of the half-shell 2 shown in FIG. 3 essentially corresponds to that of the half-shell 3 in mirror-image configuration.
  • the walls 5 and 6 of the half-shells 2 and 3, which form the spherical outer sides of the housing 1, are flat-arched, with their convex sides lying towards the outside.
  • a base 7 is formed on the underside of the housing 1, which is also composed of shell halves 39 and 40 which are integrally formed on the half-shells 2 and 3 of the housing 1.
  • the circular shape of the disc forming the housing 1 is interrupted by the base 7, without the disc-shaped basic shape of the housing 1 being lost.
  • a handle 8 is formed, which is formed from an opening which is spanned by handle bars 41 and 42, which are molded onto the half-shells 2 and 3 of the housing 1.
  • the housing 1 accommodates an extinguishing agent container 9, which largely fills the interior of the housing 1 with the exception of the base 7.
  • the extinguishing agent container 9 is also an approximately disk-shaped structure, which is arranged upright with its radial plane.
  • the upright diameter of the extinguishing agent container 9 is substantially larger than the height lying in the horizontal direction, the extinguishing agent container 9 also having a certain height in the edge region, that is to say not tapering here.
  • the extinguishing agent container 9 is composed of two dished ends 10, which are opposite each other in mirror image, and cylinder jacket sections 11 adjoining them at the edges.
  • the pressure-resistant steel extinguishing agent container 9 is welded along the edges of the cylinder jacket sections 11, so a weld seam 12 is drawn around the extinguishing agent container 9 in the upright circumferential direction, which is only interrupted by an opening on the peripheral side of the extinguishing agent container 9.
  • the extinguishing agent container 9 is held in the two half-shells 2 and 3 by means of support webs 13, which are arranged at 90 ° intervals along the periphery of the extinguishing agent container 9 so that they both the dished bottom 10 as also encompass the cylinder jacket section 11 of the half of the extinguishing agent container 9 adjacent to the relevant half-shell 2 or 3.
  • the supporting webs 13 have finger sections 14 with narrow surface sides 15 which are adapted to the contour of the bobbin lace 10.
  • the support webs 13 have system plates 16 reinforced by outer ribs.
  • the extinguishing agent container 9 has a connecting piece 17 in the form of a threaded ring, which can be seen in FIG.
  • the opening and the socket 17 lie symmetrically to the diameter plane of the extinguishing agent container 9 and thus overlap the assembled cylinder jacket sections 11.
  • the connector 17 welded along the edge of the hole projects outward in the radial direction over the assembled cylinder jacket sections 11 of the extinguishing agent container 9, which makes it possible for him to do so to secure the extinguishing agent container 9, which is a rotationally symmetrical body, against twisting or pivoting.
  • the opening of the extinguishing agent container 9 and thus the nozzle 17 are arranged halfway up on the extinguishing agent container 9, they are thus offset by 90 ° relative to the upper and lower apex area of the housing 1 and are accordingly located in the laterally outer apex area.
  • web projections 18 are integrally formed on the inside of the walls 5 of the half-shells 2 and 3, on their outer narrow surface side have an arcuate indentation 19 which, in an assembled arrangement of the half-shells 2 and 3, form-fit against the connecting piece 17 of the extinguishing agent container 9.
  • the connector 17 serves to receive a valve fitting 46 on the extinguishing agent container 9, which can be accommodated in the marginal gusset space between the assembled half-shells 2 and 3 of the housing.
  • a hose attachment piece 20 Perpendicular to the radial direction of the extinguishing agent container 9 projects from the valve fitting 46, a hose attachment piece 20, which thus points approximately in the circumferential direction of the housing 1 and emerges approximately tangentially from it.
  • a hose 21 for discharging the extinguishing agent is connected to the hose attachment piece 20, and this hose 21 lies in a hollow contour 23 which extends along the edge of the housing over its upper half. This hollow contour 23 can be seen in FIG.
  • hose attachment piece 20 In the area of the hose attachment piece 20, an indentation 24 is formed in the edge area of the two half-shells 2 and 3 and is divided into the interior of the housing by a transverse wall 44, the hose attachment piece 20 passing through this transverse wall 44.
  • a trough 25 is formed, which serves to hold an extinguishing gun 27, which is located at the end of the hose 21.
  • the extinguishing gun 27 is partially immersed in this trough 25 and is secured therein by clamping or latching webs 26 which are molded onto the half-shells 2 and 3 and protrude into the trough 25.
  • the valve fitting 46 has a striking button 28 which, if necessary, releases the extinguishing agent under pressure in the extinguishing agent container 9 via the hose line 21 to the extinguishing gun 27 if it is hammered in.
  • the striking button 28 In order to rule out an unintentional actuation of the striking button 28, it is arranged under a fuse housing 29, which can be removed from the housing 1 or from the two half-shells 2 and 3.
  • an actuating tab 45 is seated on the fuse housing 29 with a finger intervention.
  • the valve fitting 46 can have a connection for a test manometer in order to be able to determine the correct operational readiness of the extinguishing agent under pressure in the extinguishing agent container 9. So that the test pressure gauge connection is possible without opening the housing 1, the adjacent half-shell 2 of the housing 1 has a corresponding access opening 30, which is shown in FIG. 3.
  • the lateral arrangement of the valve fitting 46 on the extinguishing agent container requires 9 a riser pipe 31 in order to be able to discharge the extinguishing agent inside the extinguishing agent container under the pressure of a gas cushion as completely as possible from the extinguishing agent container 9.
  • the riser pipe 31 extends from the valve fitting 46 to the lowest point of the extinguishing agent container 9 in a constant curvature, the riser pipe 31 being able to adjust itself automatically to this lowest point.
  • it is connected to the valve fitting 46 by means of a loose pivot bearing 32, so it can rotate under the influence of gravity in relation to the valve fitting 46 in the connection area.
  • the already mentioned base 7 of the device encloses a storage space 33 which is accessible via a bottom flap 34.
  • Retaining webs 35 can be attached to the bottom flap 34, which are used, for example, to hold smoke masks.
  • an insertion device 36 can also be provided, which receives an identity card 37 on which the data of the respective fire extinguisher is stored in a computer-readable manner.
  • FIG. 3 also shows that the central region extending from top to bottom of at least one of the two half-shells 2 or 3 is curved in a special way in order to be able to apply an adhesive label provided with inscriptions thereon.
  • FIG. 3 shows only the inside of the half-shell 2, the outside is in the same way over the middle area curved in only one axis to form an inscription field 38 on the outside, the surface lines of which are straight in the horizontal direction, of which only the circumferential lines running in the vertical direction have a curvature.
  • An adhesive label bearing the lettering of the fire extinguisher can be applied to this lettering field 38, which is flat in its extended starting position.
