    description
    HYDRAULIC WORKING DEVICE The present invention relates to a hydraulic working device for portable use according to the preamble of claims 1, 9 and 16.
    TECHNOLOGICAL BACKGROUND Hydraulic tools for portable use are commonly used by the fire service for rescue operations. They have an electrically operated hydraulic pump, a battery housed in the device and swiveling tool halves. These are mainly used for cutting body parts and for spreading or opening vehicle doors. Such devices can also be used in disaster situations such. B. used in the rescue of buried victims. However, these devices often have a high weight and relatively large dimensions, so that they are often not very suitable for mobile universal use. In addition, the possible uses of such devices are limited by the type of tool halves used.
    PRINTED PRIOR ART [0003] An implement according to the preamble of claim 1 is known from the data sheet SC 357 E2 from LUKAS Hydraulik GmbH. This known implement represents a rescue device with a cutting and spreading function and comprises two tool halves which have a toothed cutting contour and form a triangular spreading contour on the front. The cutting contour ends at the expanding jaw.
    A hydraulic unit and hydraulic circuit is known from EP 0 419 810 A1. This hydraulic unit is operated by means of a manual pump unit. A compensation device in the form of a membrane and the hydraulic tank are located in the extension of the cylinder housing.
    From DE G 92 15 062 a spreader with interchangeable spreading jaws, which form a triangular spreading contour, is known. The expanding jaws are locked to the swivel arms on the device by means of removable bolts, which means that these expanding jaws can only be replaced very slowly.
    Is an implement in the form of a hydraulic spreader for accident cars is known, which has a hydraulic cylinder, a pump and a battery. The hydraulic tank and the compensation device are arranged around the hydraulic cylinder.
    OBJECT OF THE PRESENT INVENTION The object of the present invention is to provide a generic working device which enables an expanded working range.
    SOLUTION OF THE OBJECT The above object is achieved by a hydraulic working device according to the features of claim 1. Appropriate embodiments of the invention are claimed in the subclaims.
    Characterized in that each tool half has a wall-shaped section extending perpendicular to the extension of the longitudinal axis of the piston rod and both sections jointly form a flattened end region perpendicular to the extension of the longitudinal axis of the piston rod, when the two tool halves are closed, it is possible to to use the implement advantageously for spreading open door or house window gaps. Compared to conventional hand tools

    AT16 134U2 2019-02-15 Austrian
    The patent office allows the working device according to the invention with the specially trained tool very quick access to apartments or houses.
    [0010] The flattened end region is advantageously offset laterally to extend the longitudinal axis of the piston rod. As a result, the flattened end area can be inserted into a door gap without any problems, for example when the door gap is in the immediate vicinity of a door frame.
    Alternatively or additionally, the flattened end region can be oriented obliquely to extend the longitudinal axis of the piston rod. As a result, the flattened forehead area can be inserted more easily into a door gap in unfavorable space conditions.
    [0012] Both tool halves widen towards the piston rod. A tool half preferably comprises a wall region which runs at an angle to the level of the flattened end region and intersects the center line of the extension of the piston rod. This wall area supports the opening movement of the door or window.
    [0013] The tip of the flattened end region expediently has a slope. This makes it easier for the flattened end region to penetrate into a particularly narrow door gap. The bevel in particular also makes it easier to turn the flattened forehead area into a narrow door gap.
    The fact that the tool halves are arranged in the area of the flattened forehead area interlocking or overlapping one another, on the one hand a particularly narrow, flattened forehead area can be achieved, since the tool halves do not “double” in this area. On the other hand, due to the special shape of the first half of the tool, sufficient force can still be applied to the door gap.
    The tool according to the invention advantageously has at least one flat, anvil-like wall section at its end opposite the end region. This wall section serves as a stop surface in order to actively drive the flattened end region of the tool, for example with an ax or a hammer, into the door gap. This can be very advantageous if the gap is too small to penetrate with the flattened forehead area. By applying an external force, a quick penetration into the door gap is still possible.
    [0016] Advantageously, at least one of the flat wall sections has a contour. A crowbar can be attached to this contour so that the attached crowbar can be struck with a hammer or an ax. The contour has the advantage that the crowbar does not slip off the wall section when force is exerted by means of a hammer or ax. A knurl can also be provided as a contour.
    Another useful embodiment of the implement is characterized in that the tool halves additionally have a cutting contour. This cutting contour allows, for example, a safety chain attached to the door to be cut through quickly after the door is broken open.
    The above object is achieved in particular by a hydraulic implement with the features of claim 10, which are also claimed in a subordinate manner. The tool halves can advantageously be plugged onto further tool halves. This enables the tools to be exchanged particularly quickly during use.
    For example, the door opener tool described above can be designed such that it can be plugged onto these further tool halves. Both tool halves (namely those that are attached and those that are attached) each have a tool function, for example a tool function of squeezing, spreading, cutting or the like.
    In order to ensure the quickest possible tool exchange, a coupling is expediently provided for plugging and unplugging the first tool halves from the second tool halves, which comprises a locking element, which with
    2/20
    AT16 134U2 2019-02-15 Austrian
    Patent Office can be locked or unlocked a large, plate-shaped actuating element. The
    The actuating element can also be operated with thick gloves and thus ensures a quick tool change.
    The locking element is loaded with a spring and snaps into place when the first tool half is attached to the second tool half in a hole in the second tool half. The spring holds the locking element in position after the first tool half has been plugged onto the second tool half. This ensures that the tool halves are not separated from one another during work. The tool halves can be quickly separated or pulled off by actuating the actuating element.
    Advantageously, the actuating element has a preferably annular projection which is arranged opposite a corresponding bore. When the actuating element is actuated, the projection is pushed into the bore and the locking element located there is sunk into the bore. This enables trouble-free operation.
    It is advantageous that there is a beveled edge at the beginning of the second half of the tool. When the second tool halves are plugged onto the first tool halves, the bevelled edge causes the locking element to be countersunk into the bore against the force of the spring. The locking element then remains in this hole until the second half of the tool has been pushed into the first half of the tool so that the locking element has reached the hole in the coupling. The locking element is pushed up by the force of the spring, whereby the tool halves are locked.
    The tool halves serving as receptacles expediently have a, preferably toothed, cutting contour.
    [0025] Advantageously, the attached tool halves also have a, preferably rectilinear, cutting contour. This is particularly advantageous, for example, if a cable and / or a security chain has to be cut through in doors.
    It when the cutting contour of the second, attached tool halves extends the cutting contour of the first tool halves forward is particularly advantageous.
    Appropriately, the attached tool halves form a conventional triangular spreading contour.
    Furthermore, it is advantageous if the attached tool half has an internal contact surface and the cutting contour projects beyond the plane of the contact surface. This ensures that the operator does not have to search for the cutting contour first, but that it is already in the tip of the tool half. The inside contact surface offers the additional possibility of a squeeze function.
    Advantageously, the cutting contour extends into the tip of the second half of the tool, so that e.g. a cable can be cut quickly without losing the alignment of the tip of the implement without wasting time.
    A further expedient design of the working device, which is also claimed in a subordinate manner, consists in that the compensation device and the hydraulic tank are integrated together in the pump housing. This guarantees a particularly space-saving and weight-reducing design of the implement.
    The pump housing expediently has a cover which, together with the pump housing, forms a space in which the compensation device, for example in the form of a rubber membrane, is located and can extend into this space depending on the work situation. This configuration is structurally particularly simple.
    [0032] A holder for a lighting unit is expediently located on the pump housing. This is useful when using the implement in complete darkness,

    z. B. by a SEK or in poor visibility. In this way, the operator can be guaranteed at least some illumination of the work area.
    [0033] The lighting unit preferably has its own energy supply. The separation of the energy supply has the advantage that the battery for the pump cannot be used up by the lighting unit.

    [0042] FIG. 8a shows a sectional illustration in the region of the connection between the first tool half and the second tool half in the locked state;
    8b shows a sectional view in the area of the connection between the first tool half and the second tool half in the unlocked state and a sectional view in the area of the connection between the first tool half and the second tool half with the second tool half partially removed.
    Reference numeral 1 in Fig. 1 designates the hydraulic portable implement according to the invention in its entirety. The implement 1 comprises a motor housing 39, a pump housing 10, a cylinder housing 22 and a door-opening tool on the end face, which is driven by the implement. An electric motor 23 for driving a hydraulic pump 2, which is accommodated in the pump housing 10, is located in the motor housing 39. A main switch 27 is provided on the motor housing 39 for switching the implement 1 on and off. A battery 9 is used as the energy source and is inserted into a shaft on the underside of the motor housing 39 in a detachable manner.
    Reference numeral 8 denotes a control valve in the form of a so-called "star valve", which serves to control the direction of flow of the hydraulic fluid and thus the working movement of the tool (opening or closing).
    In the cylinder housing 22 there are a first cylinder chamber 46a and the second cylinder chamber 46b, which are separated from one another by the piston of a piston rod 11. The piston is in its front end position in FIG. 1. A hollow rod 5 is fixedly arranged on the pump housing 10 so that hydraulic fluid can reach the second cylinder chamber 46b from the hydraulic pump 2. A bore 47 for receiving the hollow rod 5 during the movement of the piston rod 11 and a passage opening 42 for the hydraulic fluid into the second cylinder space 46b are provided in the piston rod 11.

    AT16 134U2 2019-02-15 Austrian
    Patent Office The end of the piston rod 11 facing away from the pump housing 10 projects over an
    Deflection mechanism with two swivel arms 12, 13 in connection, which spread depending on the direction of movement of the piston rod 11 or swing towards each other. The reference number 52 denotes a retaining bolt, which is also the pivot axis of the two
    Swivel arms 12, 13 forms.
    The two swivel arms 12, 13 are formed on their end facing away from the bolt 52 as tool halves 18, 19, on which further tool halves 16, 17 are attached.
    The other tool halves 16, 17 together form a door opener tool in the exemplary embodiment.
    Fig. 1 also shows riser brackets 26, 33, which serve to attach a (not shown) riser on the implement 1. Furthermore, a handle 31 is provided on the implement 1.
    Reference numeral 25 denotes a holder for a lighting device (not shown). The lighting device is preferably equipped with its own energy supply.
    The two tool halves 16, 17 form a door or window opener tool. For this purpose, the second tool halves 16, 17 each include a vertically extending wall-like section 20, 21 with changing wall thickness. These two sections 20, 21 form on their front side in the closed state of the two tool halves 16, 17 a flattened end region 24 which runs perpendicular to the extension of the longitudinal axis of the piston rod 11. The end region 24 serves to be inserted into a front door gap or a house window gap. It enables the door opener tool to be inserted and the force to be optimally introduced into the gap. The two tool halves 16, 17 have, on the rear side opposite the flattened end region 24, flat wall sections 20a, 21a with increased material thickness, which act as a stop surface for a hammer (not shown) or an ax (not shown) or as a contact surface for a (likewise not shown) rod or a crowbar serve as a stop extension.
    The flattened end region 24 is formed in the embodiment according to FIG. 1 by a plurality of flattened wall sections 20b and 21b per tool half 16, 17 which engage with one another in a finger-like and flush manner when the tool halves 16, 17 are closed. As a result, a flattened end region 24 is formed, the vertical of which is larger than the diameter of the cylinder housing 22. The door opener tool thus offers an ideal introduction of force into a door or window gap.
    2, the flattened end region 24 of the two tool halves 16, 17 is laterally offset from the longitudinal axis A of the implement 1 or the piston rod 11. In addition, if necessary, the flattened end region 24 can be slightly inclined to extend the longitudinal axis A. This configuration enables the implement 1 to be used effectively even in confined spaces, for example in a door frame located close to a door gap.
    The front tip of the flattened end region 24 has a bevel 34 which makes it possible to press the tip of the tool into a narrow door or window gap using force.
    A hammer or an ax can be struck on the wall sections 21a and 20a running vertically to the plane of the drawing in FIG. 2, or a stop extension provided for this purpose can be attached. Reference numeral 32 denotes a cover of the two swivel arms 12, 13 of the implement.
    Fig. 3 shows the door opener tool in the open state. The two tool halves 16, 17 of the door opener tool are plugged onto the other two tool halves 18, 19. The tool halves 18, 19 form a preferably toothed cutting contour 37, 38 (see also FIG. 5), which enables a door chain to be opened after the door or window has been opened

    Cut through the patent office using the door opener tool.
    From Fig. 3 it can also be seen that in the area of the flattened or flat wall portion 20a of the tool half 16 each have a preferably transversely extending non-slip contour 40a, 40b, z. B. is provided in the form of a knurl. It is intended for a stop extension, such as. B. a crowbar, experiences a hold when hammered in and does not slip. In addition, the tool half 16 has between the flattened rear area and the individual front wall sections 20b an angularly oriented wall area 41, which serves as a stop in use.
    Fig. 4 shows an embodiment of the implement 1 according to the invention, in which there is a spreading tool with a triangular outer contour on the front of the implement 1 instead of the door opener tool of the embodiment according to FIGS. 1 to 3. This spreading tool has two tool halves 16, 17 and is also attached to the two tool halves 18, 19 in the manner already described. The type of locking is the same as that in the embodiment of FIGS. 1 to 3. The toothed cutting contour 37, 38 of the two tool halves 18, 19 can be clearly seen.
    The tool halves 16, 17 have, as can be seen from FIG. 5, an outer surface 49, 50 in the outer region, which can preferably be provided with a profiling. Furthermore, the two tool halves 16, 17 each have a contact surface 35, 36 on the inside, which can also have a profile. The contact surface 35, 36 is penetrated by a cutting contour 44, 45 which extends to the tip of the two tool halves. The cutting contour 44, 45 is preferably straight and can also easily protrude beyond the plane of the contact surfaces 35, 36. The cutting contour 44, 45 can also, as can be seen from FIG. 5, lie in the extension of the cutting contour 37, 38 of the two tool halves 18, 19, onto which the tool halves 16, 17 are attached.
    6 shows a partial view of the pump housing 10, the control valve 8 without a motor housing with an inserted, partially covered electric motor 23. The pump housing 10 has an annular projection 51, which serves to connect the cylinder housing 22 to the pump housing 10 to ensure. Also visible is the hollow rod 5 on the pump housing 10, which also serves as a line for the hydraulic fluid to the second cylinder space 46b. Numeral 6 designates further hydraulic lines which open from the pump housing 10 into the first cylinder space 46a (cf. FIG. 1).
    The implement according to the invention has a hydraulic tank 4, which is housed in the pump housing 10. For this purpose, the pump housing 10 comprises an opening which can be closed by a cover 7 and in which there is a compensating device, for example in the form of a cup-shaped rubber membrane 30. The cover 7 can be connected to the pump housing 10 by means of screws. The holder 25 for the lighting unit to be attached is located on the top.
    Fig. 7 shows an enlarged view of the tank 4 of the implement. As can be seen from this, the cover 7 forms, together with the pump housing 10 underneath, a compensation space 43, in which the compensation device in the form of, for example, the rubber membrane 30 extends more or less depending on the position of the hydraulic cylinder 3. The pump housing 10 thus comprises a tank 4, which at the same time represents the compensation volume 43 for the rubber membrane 30. As a result, the weight of the implement can be reduced considerably. In the cover 7 there is an opening 48 which allows air to escape into the compensation space 43 when the rubber membrane 30 expands.
    8 shows enlarged partial representations of a coupling 28 for the manual locking and unlocking of the tool halves 16, 17 to be plugged onto the tool halves 18, 19 in various states. The locked tool halves are shown in FIG. 8a, the unlocked tool halves in FIG. 8b and the tool halves in the state of insertion or removal in FIG. 8c.

    Patent Office Fig. 8a shows the second tool half 16, which is inserted into a recess 65 of the first tool half 18. 8a shows the locked state in which the second tool half 16 and the first tool half 18 are firmly connected to one another by the coupling 28. The coupling 28 comprises a large-area, plate-shaped actuating element 56, which is located in a recess 57, a ring 58 (see FIG. 8b) and a locking element 53. The locking element 53 is located in a bore 54 in the tool half 16 and is by a spring 55 biased towards the actuator 56.
    In the embodiment shown here, the actuating element 56 has a, preferably annular, projection 60, which cooperates with a recess 62, which is designed in the form of a ring, so that the actuating element 56 can be pressed. The actuating element 56 expediently has a further central projection 67 which lies opposite a bore 66 on the tool half 18. The bore 66 is useful in order to create space for the locking element 53 for locking the tool halves 16, 18. The projection 67 serves to sink the locking element 53 out of the bore 66 against the force of the spring 55 into the bore 54 when the actuating element 56 is actuated. This allows the clutch 28 to be unlocked. In addition to the bore 66 there is an annular projection 61. The projection 61 is opposite a corresponding recess 63 in the actuating element 56. The projection 61 is sunk into this recess 63 when the actuating element 56 is actuated. A guidance of the actuating element 56 is thereby achieved.
    The unlocked state is shown in FIG. 8b. Here, the locking element 53 is completely countersunk in the bore 54 and the actuating element 56 is pressed in by the operator. The actuating element 56 has an annular recess 59 on the outside. In the locked position (FIG. 8a), the recess 59 is filled by the ring 58 and thus an actuating plane of the actuating element 56 which is flush with the surface of the tool 18 is reached.
    8c shows how the second tool half 16 is plugged onto the first tool half 18 and how these can be separated from one another. The locking element 53 is pressed out due to the force of the spring 55 when the second tool half 16 is pulled out of the bore 54 at the beginning of a beveled edge 64 located on the first tool half 18. The beveled edge 64 serves as a run-on bevel when the second tool half 16 is plugged onto the first tool half 18, the locking element 53 being pressed into the bore 54 when being pushed through the beveled edge 64 and then being immersed in the bore 54 when it reaches the bore 66. As a result, the second tool half 16 is locked with the first tool half 18.
    The implement according to the invention is characterized by a low weight and small dimensions. Furthermore, it offers a very high variability in use and is therefore particularly suitable as an accompanying tool for firefighters with the possibility of quick access to a building. Likewise, the working device according to the invention is very particularly suitable for the use of SEK.
