Definitions

• the invention relates to a device for manual gripping and transporting heavy, bulky
• Machine-driven vehicles are used to transport heavy, unwieldy objects, such as decorative stones for landscaping and gardening, and mechanical lifting and gripping devices are used for loading and unloading. If machines of this type are not available or cannot be used, since their use would destroy the ground, for example in the case of an ornamental lawn, the manual transport of such rounded, heavy stones is extreme arduous and only manageable by several people. The design of a park landscape with decorative stones of this type is therefore personnel-intensive and time-consuming for landscaping and gardening companies if no mechanical, motor-driven devices can be used for transporting or accurately inserting such stones.
• the invention has for its object to provide a generic device in which the levers of the transport device can be freely disassembled without manipulation of the joint, in which tilting of the levers in the region of the joint is prevented and which safely grasp and transport irregular heavy objects enables.
• one of the levers is double-walled and the other lever can be inserted into the space formed by the webs, the webs being the guide for pivoting the levers in that the joint is arranged by at least one on the top of the lever , Axle extending transversely to the longitudinal direction of the lever and at least one arranged on the top of the other lever, partially encompassing the axis, hook-shaped open axle bracket is formed, the axle being freely removable from the opening of the axle bracket so that the gripping member of the double web Heb els than the object is at least partially comprehensive gripping fork and that the stylus elements of both levers with two legs are approximately U-shaped.
• the object to be transported or lifted is located approximately in the middle of the device according to the invention, so that the load-bearing capacity for the people who can carry the device with the object on opposite sides , is about the same. This ensures an optimal load distribution.
• the approximately parallel to the floor lever or handle elements also ensures that the handle elements are optimally held by the carrying personnel in the upright position and the entire device can be transported with the object in this way without the risk that one of the stylus elements slips out of the wearer's hand.
• the webs of one lever act as a guide for pivoting the lever, so that tilting in the joint area is prevented with asymmetrical and uneven objects.
• the interlocking of the levers can be carried out to transport the object in such a way that the double-walled lever with its gripping member is placed over the object to be transported and the other lever with its gripping member is inserted through the space between the webs and the axle is connected to the axle holder.
• the axis brackets on the top of the webs of one lever can be arranged approximately in alignment with one another, so that an exact detection of the axis of the other lever is made possible.
• the open side of the axle brackets designed as hooks preferably faces the handle element of the other lever.
• the device designed in this way can be released by simply pushing it against one another and disassembled into its two components.
• the objects to be transported in practice can have completely different shapes. It is therefore of great importance that the gripping width of the gripping members can be adapted to the circumference or the external shape of the objects to be transported. This can be achieved by using several hooks are provided for receiving the axis one behind the other, with any inaccuracies that still exist can be corrected by slightly pivoting the levers from the position parallel to the ground, without impairing grip safety.
• the radius of the axis and the inner radius of curvature of the hooks preferably coincide approximately, so that the hooks can encompass the axis in a form-fitting manner.
• the other gripping member preferably has a single-pronged finger shape partially encompassing the object.
• the fork-shaped gripping member is preferably connected to the double stegi gene lever, while the finger-shaped single-pronged gripping member is arranged on the single-pronged lever. This arrangement makes it possible to guide the finger-shaped single-pronged gripping member through the space between the webs, to connect the axle to the hooks acting as axle holders, to align the levers or stylus elements parallel to the floor, and to lift and transport the object.
• the levers and the gripping members are preferably welded together from torsion-resistant square tube, the fork or the finger-shaped part of the gripping members each extending in the longitudinal direction of the levers.
• the handle elements which are arranged on both levers, are U-shaped, the opposite legs being at a distance from one another, which enables a transport person to grasp the ends of the handle elements between the Thighs can kick and can grip the thighs with arms or hands hanging on the side of the upper body.
• the U-shaped handle elements preferably consist of a torsionally rigid tube, wherein each handle element can be connected in one piece to the corresponding levers by welding.
• the design of the handle elements as a hollow tube gives the entire device a low weight, the round profile being easily grasped by a human hand.
• the handle elements In order to increase the comfort for the carrier width, it is possible for the handle elements to have ergonomically designed handles.
• the handles can be made of wood and inserted into the openings of the hollow tube, but it is also possible, for. B. Pull rubber grips over the ends.
• the device is preferably operated by two people facing each other. In the case of very heavy objects, however, it is also possible to place about four or more people on the U-shaped handle elements and to carry them out in this way. On the other hand, in the case of lighter objects, it is possible to provide one of the handle elements with a support frame which can roll over one or more lower rollers on the surface. Such an arrangement is preferably chosen when the ground is flat or slightly sloping. In this way it is possible for only one person to operate the device.
• the support frame is preferably inserted into an opening of the tubular profile by means of a connecting part, so that there is a secure connection between the support frame and the handle element.
• a connecting part to cover larger distances, it is also possible to connect the other side of the device with such a support frame so that a person can move the load to be transported simply by pushing or pulling can.
• the support frames can be designed to be variable in height, the height being adjustable, for example, by means of a threaded rod which can be rotated by a crank or in a known manner.
• these can have articulated holding members which automatically adapt to the shape of the object to be transported during operation of the pliers. These holding members can be used to increase the friction forces with this purpose-serving surface structures, such as corrugation.
• the device can be hot-dip galvanized or provided with an appropriate coating.
• the transport of heavy planters and barrels is also possible in that the width of the gripping members can be adapted to the outer shape of the object to be transported.
• heavy overturned flower pots can be gripped with the device and erected again.
• the device is placed over the overturned bucket in a manner similar to that of a stone, the levers are aligned approximately in alignment, and the flower bucket is erected again by pressing and pulling on the U-shaped handle elements using the lever force.
• the device according to the invention can, for. B. in the area the handle elements, including z. B. attached to chains, ropes, hooks or the like and raised.
• the device is not only suitable for manual transport, it can, for. B. thereby also be attached to the extension arm of a crane or other lifting device, so that, for. B. the unloading of heavy objects from a truck or transport with the help of mechanical hoists.
