Definitions

  • the present invention relates to a grip element for a gas bottle which has a gas bottle body.
  • Gas bottles for which grip elements are an integrated component are known in the art.
  • the grip elements are configured in form of handles in one piece with the gas bottle in such a manner that the gas bottles can be lifted and moved away.
  • such grip elements are not provided.
  • technical gases are used which are usually delivered in 50 litre compressed gas bottles and which, depending on type and fill factor, weigh about 80 kg.
  • 50 litre bottles with a 200 bar filling pressure weigh approximately 80 kg.
  • 300 bar filling pressure bottles weigh approximately 115 kg.
  • Most of these gas bottles are used as protective gas bottles.
  • these gas bottles are most of the time fixed on a platform situated on the welding device. This platform is situated depending on the construction type of the welding device at a height of 130 to 250 mm above the floor. This being, depending on the intensity of the welding work, a regular change of the gas bottles is foresee.
  • the gas bottles must also be moved to another place in a workshop. This being, the round bottles can be inclined and rolled on the edge about their lower end. They can also be moved with different transport cars. However, for safety reasons, it is not appropriate to roll the bottles if they are in a horizontal position.
  • the object of the invention is to make available a grip element of the above mentioned type which makes the lifting and moving of gas bottles safe from an ergonomic and safety aspect.
  • the gas bottle body can be clamped between two clamping blocks of the grip element which, in turn, can be pressed against the gas bottle body.
  • the clamping blocks are provided with one handle each, wherein the handles are moved upwardly if a lifting force is applied.
  • the basic idea of the invention is that the grip element secures the gas bottle with a high application pressure between the gas bottle wall and the surfaces of the clamping blocks.
  • the necessary high application pressure can be achieved in that an upward movement of the handles is set into motion so that the lifting forces are transferred to the surface of the gas bottle.
  • the clamping blocks press stronger against the gas bottle during the lifting operation and a safe grip without skid risk is realized.
  • the clamping blocks clamp the gas bottle body in such a manner that the biggest possible contact surface is obtained. Clamped in this manner, the gas bottle can now be lifted and moved by one person.
  • the grip element has a connection stirrup bent to a bow which is provided at both ends with one clamping block, respectively.
  • the grip element can be laid in particular around round gas bottles so that the connection stirrup is situated on the operator side.
  • a preferred embodiment of the invention provides for that the clamping blocks are respectively provided with a rubber lining which is in contact with the gas bottle body. This takes into consideration the fact that rubber linings which are situated on the clamping blocks increase the bonding between the clamping block and the gas bottle.
  • a clamping jaw is mounted in the clamping block, whereby the clamping jaw is provided with a bore and the clamping block with a bore for receiving a pin, whereby the clamping jaw with the bore is positioned on the pin which is situated in the clamping block.
  • the clamping block can be provided laterally with a bore with a diameter of 8 mm for receiving a straight pin which carries the clamping jaw.
  • the clamping jaw is provided with a lateral bore with a diameter of 8 mm with which it is positioned on the straighter pin which is situated in the clamping block.
  • the clamping block is provided with a bore with which the clamping block is positioned rotatably on the connection stirrup.
  • the clamping jaw can be provided with a small in particular square surface on the side turned to the gas bottle body.
  • the clamping jaw mounted in the clamping block can be turned away from the gas bottle body by approximately up to 27°.
  • the clamping block is provided with a rubber block provided with a steel insert on the side turned to the gas bottle body.
  • a handle can be fixed with a screw in a thread. Radially around this threaded bore, three bores can be set for fitting pins on the clamping block. It is possible here to fix the handle in three different positions and to secure it against torsion. This being, the respective handle can be provided with a tight fitting pin.
  • the grip element is adjustable in such a manner that the clamping blocks adapt themselves to the different diameters of the gas bottle body.
  • the clamping blocks are mounted on adjusting screws in such a manner that the clamping blocks can be moved in direction to each other or away from each other.
  • the handles can be positioned rotatable, in particular around the connection stirrup, so that when the grip element is not used, a space saving arrangement thereof is possible.
  • the space saving arrangement is characterized in that the handles are situated in the surface between the two ends of the connection stirrup. According to the terminology used here, this space saving arrangement is also designated as inoperative position.
  • An additional rubber lining can be placed in an inner vertex of the connection stirrup for a damping between the gas bottle body and the connection stirrup.
  • a practicable alternative of the invention provides for that a torsion spring is integrated into the clamping blocks.
  • the torsion spring can thus always bring the handles into the inoperative position.
  • the torsion springs can be so strong that they push the clamping blocks against the bottle wall when putting the grip element against a gas bottle in such a manner that the grip element holds itself on the gas bottle.
  • the clamping blocks can be made of a massive aluminum block, But it is also conceivable that the clamping blocks are made of another material which seems appropriate. It is possible that the rubber linings on the clamping blocks are round or rectangular.
  • the connection stirrup can be made of circular tube, square tube or any other profile. But it can also be completely configured as cast part. But any material can also be used as material as long as it is sure that the material has the necessary strength.
  • the possibility for adjustment of the grip element is provided for in a range of approximately 209 mm to 232 mm. This proves to be judicious since gas bottle bodies with the diameters 204 mm, 219 mm as well as 229 mm belong to the prior art.
  • a further advantageous configuration of the invention provides that the clamping blocks are positioned on stud bolts of the connection stirrup with eccentrically bored bushes, whereby during a rotation of the bushes about approximately 180° there is a width adjustment from centre to centre of the bushes to each other.
  • the bushes can be made of plastic.
  • the width adjustment covers approximately 23 mm.
  • the bushes have a square configuration of a stud bolt bore on their side turned to the connection stirrup, wherein the bushes are secured against torsion on the stud bolts on a square stud of the otherwise round bushes.
  • the square stud has a height of approximately 10 mm, whereas the square configurations of the stud bolt bore are approximately 10 mm deep.
  • the bushes are secured against torsion on fitting pins which are inserted in the clamping block and penetrate into the bores of the head edge.
  • the number of the fitting pins can vary.
  • the plastic bushes have on their side opposite the connection stirrup a bored opening of the stud bolt bore with a dimension which guarantees the fitting of a compression spring with at least 10 mm spring excursion.
  • the compression spring can be held by a spring plate which is fixed on the stud bolt of the clamping blocks for example by means of a spring washer.
  • the head of the plastic bush is designed so big that the clamping blocks positioned on the plastic bushes are held by the bushes.
  • the head of the plastic bushes is provided with a knurled handy edge and has respectively three radially arranged marks which indicate the position of the bush relatively to a mark on the respective clamping block.
  • the invention also provides for that the clamping blocks are equipped with a bore which receives the plastic bush.
  • the eccentric bush can be twisted in catch paces of 90° by pulling off on its handy configured head part from the square stud of its stud bolt which corresponds, for an embodiment in pairs, respectively to another gas bottle size. In its inoperative position, an unintended twisting is avoided by the compression spring integrated in the head part of the bush which pushes the bush onto the stud bolt and onto the square stud which is situated there.
  • the position of the eccentric bush is indicated by the marks made on its head and on the clamping block which indicate the bottle diameter which can just be grasped when the clamping blocks with their rubber linings are turned to each other.

  • FIG. 1 c shows that both handles 13 , 14 are in the inoperative position.
  • the inoperative position of the grip element 100 has the advantage that the grip element 100 takes a space saving position when it is not used.
  • a torsion spring which always brings the handles 13 , 13 into the inoperative position can be integrated into the clamping blocks 10 , 11 .
  • the torsion springs can be configured so strong that, when the grip element 100 is put against a gas bottle, the clamping blocks 10 , 11 are pushed against the bottle wall so that the grip element 100 keeps itself to the gas bottle.
  • an additional rubber lining 21 can be placed in the inner vertex of the connection stirrup 12 , this rubber lining assuring a damping between the grip element 100 and a gas bottle.
  • a gas bottle body 18 of a gas bottle 17 can be seen which is clamped between two clamping blocks 10 , 11 of the grip element 100 .
