Definitions
- the invention relates to a device for lifting an object, in particular Wooden plate, wooden beam or wooden wide-stack element, with the attachment the device alone on the top of the object to be lifted takes place and can be carried out with little effort and effort and again is solvable.
- One way to do this is to lift the bottom of the Subject e.g. to carry one or more shoulder straps, the ends of which be guided upwards and subjected to the required lifting force.
- the disadvantage here is that the object to be lifted from its base must be spaced so that the shoulder strap is arranged in a suitable manner can be.
- the object to be lifted must first either lifted by hand or using a suitable auxiliary mechanism be or on supports through which he is sufficient of his pad is spaced, stored, which means a considerable effort.
- suitable suspension elements such as Attach screw hooks or eyelets.
- An advantage here is that the attachment of suitable suspension elements in many cases from the top of the object to be lifted is possible, so that the object to be lifted is not off its surface must be spaced.
- the disadvantage here is that with the attachment suitable suspension elements connected considerable effort.
- the disadvantage is the need for the attached suspension elements to remove later, e.g. because they're handling that space-saving storage, processing or use of the obstacle to lifting object or e.g. for cost reasons to be reused for lifting other objects.
- Another possibility is to lift the object to be lifted its side surfaces with a suitable mechanical gripping mechanism to understand.
- the disadvantage is that the gripping mechanism in many Cases specifically according to the dimensions or shape of the lifting objects must be trained. Furthermore, here is in disadvantageous in many cases that the side surfaces of the objects to be lifted are subjected to heavy use by the gripping process, what especially with frequent repetition of damage or Wear of the object to be lifted.
- Another possibility is to use one or more suction devices for lifting an object.
- the disadvantage here are This requires great effort and the limitation of applicability on objects with sufficiently tensile, smooth surfaces.
- 199 62 127 C2 is a device for lifting objects, in particular known wooden panels, wooden beams or wooden wide stacking elements.
- This device comprises a rigid compression rod on which in the area the ends of which each engage a tension rod, each at their upper ends are connected to a connecting bridge and together with the pressure rod as Base an isosceles triangle on the base.
- At the ends of the Pressure rod are oblique guide sleeves that serve as drilling templates are arranged, their longitudinal axes in one plane with the triangle lie and intersect at a point below or above the Pressure rod is close to or in the projection of its center.
- In the Guide sleeves are manually insertable, which after inserting the Extend the guide sleeves below the pressure rod.
- the one to be lifted The object has at least two holes that continue in the Guide sleeves have been drilled diagonally into the object.
- the the Part of the mandrel protruding downwards can be turned into one of each Bores engage, making the device releasable with the one to be lifted Object is connected.
- the pressure rod is hinged to the Tension rods articulated that the compression rod by one to its longitudinal direction parallel axis can be pivoted relative to the tension rods.
- a disadvantage of this lifting device is the possibility that the Incorrectly insert mandrels into the guide sleeves, without being noticed.
- spines which were initially fully inserted into the guide sleeves, e.g. by virtue of of vibrations gradually move out of the holes.
- the mandrels are not or no longer far engage enough in the holes and therefore out with the lifting material lifted break out the holes laterally, which is not only serious damage of the goods to be lifted, but also a serious security risk represents.
- Another disadvantage of this lifting device is that tilting moments and bending stresses occur when the projection of the point of application of the Lifting power compared to the projection of the center of gravity of the to be lifted Object is moved transversely to the longitudinal direction of the pressure rod.
- This can also be conventionally provided by joints, a pivotal movement of the raised object against the Tension rods to allow an axis parallel to the cross member, not completely avoid what is structurally disadvantageous and the risk of Broken material increased.
- the invention is based on the object of the disadvantages mentioned avoid, as it is based on the task, a device for To provide lifting of objects regardless of the surface condition of the object to be lifted, where the attachment of the object to be lifted only from the front can be repeated as often as desired with very little material effort and with very little effort and effort very quickly and again can be solved without hanging elements on the lifting to be lifted To attach the object without exposing it to wear and tear without first having to distance it from its base.
- the longitudinal axes of the guide sleeves do not necessarily have to be in intersect a point, i.e. the longitudinal axes do not have to be in one plane lie. Rather, they can be mutual in a certain mutual Cross the minimum distance without lying in one plane.
- the area in which the longitudinal axes cross is the area of the intersection or the area in which the least mutual Decency between the longitudinal axes is reached.
- the object is further achieved by a lifting device for lifting a Object, in particular wooden panel, wooden beam or wooden board stacking element, which two of the devices explained above with a total of four tension elements comprises which two devices so by means of a traverse coupled that a lifting force acting on the crossbar at the same time can be introduced into the object via all four tension elements.
- the lifting force required to lift the object can e.g. by a crane are exercised and will be at the top of the triangle or at the top Short side, i.e. the side of the square opposite the cross beam initiated device according to the invention. This is according to the invention able to apply the lifting force to the object to be lifted.
- the device according to the invention is to be lifted Object preferably placed so that the triangle or Square spanned plane stands vertically and through the center of gravity of the lifting object runs and the point at which the lifting force is introduced into the device, in the vertical projection of the center of gravity of the object to be lifted.

- the object to be lifted is provided with holes once, the Longitudinal axes coincide with those of the guide sleeves, the The diameter of the holes corresponds at least to that of the mandrels.
- the guide sleeves can be according to an embodiment of the invention can be used advantageously as drilling templates.
- the holes can completely penetrate the object to be lifted, However, they are particularly important if the object to be lifted is sufficient Has thickness, preferably designed as blind holes, so that the underside of the object to be lifted can remain unchanged and the holes are invisible from below. This is especially true of great advantage if the objects to be lifted are installed later that only its underside is visible, e.g. Elements of a Ceiling covering for a living room.
- the thorns are used for the device according to the invention through the guide sleeves into the Holes introduced.
- Each of the mandrels preferably has a handle.
- the longitudinal axes of the guide sleeves take one according to the invention such an angle with respect to the vertical that they are at one point cross, which is below or above the crossbar and its vertical projection on the cross bar between the points of attack. Therefore, the mutual distance between the lower ends of the in the guide sleeves and drilling inserted mandrels either less or greater than the mutual distance of their upper ends. So one is at the top of the triangle or on the top transverse side of the square vertically upwards attacking lifting force over the tension elements, the cross bar, the mandrels and either the inwardly facing parts of the walls of the holes or the outwardly facing part of the walls of the holes in the initiated lifting object.
- the device can thus according to the invention in very short time and with very little effort and effort as often as you like repeatedly attached to the object to be lifted and again by same be solved.
- the mandrels are each means a releasable locking mechanism against displacement of the mandrels can be secured relative to the guide sleeves in the longitudinal direction thereof.
- the locking mechanism is set up that if the mandrel is not fully inserted into the guide sleeve cannot be activated, i.e. the locking mechanism only allows locking the mandrel when it is fully inserted; otherwise it is no locking possible.

- the locking mechanism can advantageously be coupled to a warning device be which, when the locking mechanism is not activated, is an optical and / or is able to trigger an acoustic warning signal. That way prevent it from going unnoticed if a thorn just mistakenly is inserted incompletely into the guide sleeves or if it is mistakenly not activated locking mechanism begins to migrate from the hole.
- the warning device can be designed such that It only triggers the warning signal when an object is attempted with the help of a tool according to the invention during the Locking mechanism is not activated.
- the warning device can e.g. one Quiescent current contactor and a siren or flashing light connected to it include, the contactor when not fully inserted Dorn releases the power supply to the siren or flashing light and otherwise interrupts.
