Abstract

Device for receiving and transporting at least one conical hollow body (11) with an upper-side opening, with an unlockable locking mechanism (6) for retaining already received hollow bodies (11) and an actuating device (1) for a gripping mechanism (7) which can be spread transversely to the longitudinal axis of the device ) which is elongated in its receiving position and in the top-side opening of the hollow body (11) is inserted, which it receives in its transport position by means located at its periphery hinge body (5) positive and / or non-positively and completely or partially via the locking mechanism (6 ) lifts.

Description

The invention relates to a manually operated device, hereinafter also called gripper, for easy picking up and transporting at least one open-top, conical hollow body, such as open-top signal cones or pylons.

Various systems for lifting and carrying devices for different forms of hollow bodies are already known, reference being subsequently made only to devices acting on the hollow body from the inside, since these can accommodate a plurality of hollow bodies.

Such devices are usually designed specifically for certain geometries of hollow bodies. This is within the scope of process automation in which the short-term picking up of a single hollow body, e.g. B. a bottle plays a role. Furthermore, devices with greater flexibility in terms of male hollow body are known, but above all work with non-positive retention mechanisms and are only suitable for the manipulation of a respective hollow body.

From the DE 41 01 954 A1 is a device for setting up and collecting road markings, in particular signal cones known. However, this device is designed as a structure for a motor vehicle and thus suitable only for use by driving license holder but not for manual use.

From the DE 10 2006 007 820 A1 is a laying manipulator for positioning and joining of hollow parts and pipes known. This is designed as an assembly for the boom of an excavator and takes by means of a spreading and / or telescoping mandrel to be manipulated hollow body individually and non-positively. This device is also unsuitable for manual use.

From the DE 25 11 98 a holder for tubular body is known which presses on an expandable housing part applied friction surfaces from the inside against the plugged hollow body and this receives. The recording is force-fitting. But even this device suitable only for the manipulation of individual hollow body.

The object of the invention is to provide a simple, inexpensive and manually operated device, which is suitable for simultaneously receiving and transporting a plurality of conical, open-topped hollow body, in particular signal cone. The device should be able to be used independently of location, so work without exhaust and noise.

According to the invention the object is achieved by a device having the features of claim 1. Advantageous embodiments of the invention are the subject of dependent claims.

The inventive device for receiving and transporting open-top, conical hollow bodies is rod-shaped, so that the user standing on the ground can easily absorb hollow body. The user does not have to bend or kneel to pick up the hollow body.

The subsequent designations upper and lower end of the device refer to the position of the device during use. The device has an upper end actuator operatively connected to a lower end gripping mechanism. Preferably, the device according to the invention has a handle located at the upper end, or the device itself is formed on the upper side as a handle.

The gripping mechanism may assume two states which can be exchanged by the actuating device, namely a spread-out and an elongated state. Hereinafter, the spread state is also referred to as the transport position and the elongated state as the pickup position. In a preferred embodiment, a spring force acts in such a way that the device is unactuated in the spread-out state, transitions into the elongated state by actuation of the actuating device, counter to the spring force, and then automatically returns to the spread-out state. If the actuator is not actuated, the gripping mechanism is in the expanded state, wherein its transverse extent (the extent transverse to the longitudinal axis of the device) is greater than that of the top-side opening of the hollow body to be accommodated. When the actuating mechanism is triggered, the gripping mechanism transitions to the elongated state. He expands in the direction of the longitudinal axis of the device and thereby reduces its transverse extent transverse to this direction.

If the gripping mechanism is elongated by the actuating device, that is transferred from the spread-out to the elongated state, it can be introduced through the upper opening in the hollow body. By loosening the actuator of the gripping mechanism goes into its spread-out state, wherein it receives the hollow body in a form-fitting manner.

During the transition of the gripping mechanism from the elongated to the expanded state, determining the circumference of the gripping mechanism, Hinged body movement towards the handle. Since these simultaneously form the support points for the hollow body, this is lifted in the direction of the upper end of the device.

By this lifting of the hollow body is pushed over a locking mechanism. This locking mechanism is similar to the snap mechanism of common umbrella designs for keeping the umbrella open.

The locking mechanism is preferably designed as a protruding from the device triangle, which is pressed by a spring to the outside. The triangle with the device preferably forms an acute angle at the bottom and an approximately right angle at the top. As a result, hollow bodies which are lifted by the gripping mechanism are pushed over the locking mechanism, the hollow body being pushed over the acute angle of the triangle during lifting and thereby pushing the triangle into the device. After the hollow body has been pushed over the locking device, it is again pressed outwards and prevents slipping down of the received hollow body.

Advantageously, the gripping mechanism after lifting the hollow body via the locking mechanism again for receiving or lifting a further hollow body available.

Preferably, the locking mechanism is to be released by means of a releasable in the vicinity of the actuator release mechanism to release the recorded hollow body again.

Hereinafter, a preferred embodiment will be explained with reference to drawings.

Show it:

1 a view of the gripper with elongated gripping mechanism, and

2 a view of the gripper with herausgespreizten gripping mechanism.

The in 1 shown gripper has a rod-shaped housing 4 on. This is designed as a hollow cylinder. An inside rod 8th is guided inside this hollow cylinder. The pole 8th is with a lower joint body 10 one at the bottom of the case 4 located gripping mechanism 7 connected. Thus, the at least four joints 9 existing gripping mechanism 7 by downward movement of the inner rod 8th elongated. In the relaxed state is the gripping mechanism 7 spread out.

The movement of the inside rod 8th is caused by an actuating mechanism, here as a push button 1 is trained. Thus, an operation of the push button leads 1 to an elongation of the gripping mechanism 7 this reduces its scope. In the elongated state ( 1 ) can be the gripping mechanism 7 so in the upper opening of a hollow body to be lifted 11 be introduced. This can be one or more already lifted hollow body 11 on a locking mechanism 6 rest. By relaxing the operating mechanism 1 provides a restoring force for upward movement of the inner rod 8th , causing the central joint body 5 to move up and out while the hollow body 11 record both form-fitting, as well as their upper opening on the locking mechanism 6 slide. The restoring forces are characterized by prestressed middle joint body 5 , provided by means of ring springs. However, embodiments are also possible in which in the housing 4 accommodated springs or pneumatic devices provide the restoring force. To turn off the hollow body 11 can the locking mechanism 6 by an operating element, in particular a lever 3 , near the handle 2 dissolved and in whole or in part inside the case 4 be sunk.
