Definitions
- the invention relates to a hand-operated tool with one versus one Housing swiveling handle, a drive rod, which by means of a is axially adjustable by the handle actuated drive mechanism, one first and a second push rod, at the front ends of which are first and second Pistons are attached, the drive rod and the push rods in one plane lie and the push rods with the push rod in the area of their rear ends are connected via a connecting bar.
- Such tools are used, for example, in used in the construction industry to lay sealants, but also for others Such tools with this structure are known for their intended use.
- Such hand-operated Tools are for example in the publications listed below shown and described: EP-OS 645 194; GB-PS 703 780; U.S. PS 4,135,644; U.S. Patent 5,052,243; EP-OS 108 584; WO 89/01322.
- twin cartridges are also commercially available, which have two hollow chambers in which there are two different components are that can be squeezed out and mixed at the same time. Different embodiments of tools with which such twin cartridges can be squeezed out are known.
- the US-PS 4 566 610 shows a tool in which the two push rods for the two chambers of the cartridge each have their own drive. Disadvantages are the large space requirement for the two separate drives and the increased effort in manufacturing.
- a tool of the type mentioned at the beginning which is also previously known, overcomes these problems by using the two push rods and the push rod placed on one level. So that the cartridge and the drive rod are not in the way, the drive rod is not halfway between the two Push rods arranged, but laterally offset from it, and within of the envelope circle of one of the pistons (in axial view). When squeezing the cartridge when moving its bottom by means of the piston, the free end of the Immerse the drive rod in the now hollow rear area of the cartridge.
- this construction is due to the space required for the drive mechanism can only be used to a limited extent. For cartridges with a smaller diameter than 40 mm, a practical implementation of the construction is no longer possible. Another disadvantage is the highly asymmetrical load on the connecting bar.
- the object of the invention is to provide an improved hand-operated tool Provide mentioned type, which has the disadvantages of the known constructions overcomes.
- this succeeds with a hand-operated tool at the beginning mentioned type in that the second piston additionally at the front end of the Drive rod is attached.
- the invention recognizes that space is created for the drive mechanism can be if the drive rod is also connected to the one piston which acts as a "third push rod". Furthermore, through the Construction according to the invention very high forces can be applied, only slight asymmetrical loads occur.
- FIG. 1 is a schematic plan view of a first embodiment of the invention
- Fig. 2 is a side view of this embodiment
- Fig. 3 is a schematic Representation of a second embodiment of the invention.
- the hand-operated tool shown in FIGS. 1 and 2 has one opposite a housing 1 pivotable handle 2.
- the housing 1 is in the Figures not shown drive mechanism provided, as in such Tools are used and which can be actuated by the handle 2 and via which a drive rod 4 can be gradually adjusted axially.
- drive mechanism is not the subject of this invention and is already different Forms of drive mechanisms that can be used here have become known the drive mechanism is not described further here.
- the tool also has a first and a second push rod 5, 6 the front ends of which are fastened to first and second pistons 7, 8.
- the first Push rod 5 can act on the first piston 7 in the middle or off-center, whereas the second push rod 6 is attached to the second piston 8 off-center is.
- the front end of the drive rod 4 is also rigid with the second Piston 8 connected. According to the embodiment of FIGS. 1 and 2 engages the drive rod 4 off-center on the second piston 8.
- the push rods 5, 6 and the drive rod 4 are arranged parallel to one another and lie on a common level. They are in the area of their rear ends Push rods 5, 6 and the drive rod 4 to one another via a connecting bar 10 connected.
- the tool is used with a conventional twin cartridge that can be inserted into the support frame 9 when the pistons 7, 8 are retracted.
- holding elements 15, 16 for the cartridge are provided on the carrier frame 9.
- the push rods 5, 6 by repeated pivoting of the Handle 2 moved forward.
- the forces that occur are from the construction according to the invention with only slight asymmetrical Loads absorbed almost without torsion.
- An inventive Tool can also be designed for relatively small cartridges, the drive mechanism nevertheless due to the optimal use of space between the push rods 5, 6 place.
- the two pistons 7, 8 have the same diameter or areas.
- Fig. 3 an embodiment of the invention is shown schematically, which is suitable for twin cartridges with chambers that have different sizes.
- the pistons 7, 8 have different diameters or areas F 1 , F 2 .
- the arrangement of the drive rod 4 on the connecting bar 10 can be off-center in this case.
- the criterion to be used is that the ratio between the distance 12 between the first push rod 5 and the drive rod 4 and the distance 13 between the drive rod 4 and the center line 14 through the second piston 8 is as possible the ratio between the area F 2 of the second piston 8 and the area F 1 of the first piston 7 should correspond.
- the center line 14 through the second piston 8 is defined by the surface normal to the second piston 8, which leads through the center of the second piston 8. Since the areas F 1 , F 2 and the distance between the first and the second pistons 7, 8 are predetermined by the format of the cartridge used, the attachment point 11 of the drive rod 4 on the connecting bar 10 remains as a free parameter, which corresponds as far as possible to the specified ratio is chosen. In the case of first and second pistons 7, 8 of the same size, as in the exemplary embodiment according to FIGS. 1 and 2, this requirement cannot be met exactly.
