Patent application US2014203579A1 discloses a foldable pet feces pickup device includes a handle, upper operating stick, and a lower operating stick. The device further includes a linkage accessory connecting the upper operating stick to the lower operating stick. The linkage accessory has an elongated shape with round convex parts. The device further includes a pair of picking-up members for picking up an object; and a shaft connecting the lower operation stick and the pair of picking-up members. If the upper operating stick is moved toward the handle, the pair of picking-up members moves away from each other to open. If the upper operating stick is moved away from the handle, the pair of picking-up members moves toward each other to close. The device is foldable at the linkage portion. Patent application WO2010072833A1 discloses A manual tool that can be used for gathering waste material is described. The tool includes a pair of opposing blades that cooperate with one another to enable the user to scoop scrape and gather in a single device.

Patent application WO2012026860A1 discloses a hand tool for in one action picking up objects, solid objects and also slugs and similar slimy animals, and collecting them in an attached collection bag. The collection bag can easily be removed from the tool and either knotted up and disposed of or emptied and re-used. The animals can be killed in the same collecting action through the grip claws that are gripping the animal being drawn through a detachable knife blade whereupon the animal is split into two parts before they end up in the collection bag. The tool is characterised particularly by the fact that on depression of the handle the upper grip claw moves towards the lower grip claw (which is spring-loaded against the mount and still static) and when these make mechanical contact (through contact with each other or an intervening object) the lower claw holds firm and grips the object. On further depression of the handle the lower static grip claw begins to move and rotates with the upper. With the object in a grip between the grip claws these rotate on to a point where the grip is opened and the object is thrown in the direction of rotation of the grip claws. The bag or container is positioned in its way for collection.

Patent application WO2013167776A1 discloses a mechanical device designed for collecting dog excrement, consisting substantially of a telescopic pole with a handle, provided at its upper end with a walking leash.

The disadvantage of the known solutions is their insufficient degree of operational automation. The known grabbers require the lever to be physically actuated to trigger the grabber, whereas the presented grabber actuates automatically upon touching an obstacle (the ground).

Another drawback of the known grabbers is the method of operation thereof and the manner of carrying the grabbed items - they require both hands, whereas the presented device can be used to grab an object, move it, and drop it by using only one hand.

The object of the invention is distinguished by ease of use, as well as the speed and precision of grabbing. Is also characterised by the manner of collecting items, which is easy and clean for the operator.

The grabbing device consisting of a rod, jaw grabber and two-sided support arms, according to the invention, is characterised in that in the rod there is a movable shaft longer than the rod and whose one end is attached to a pin of a hinge connecting the jaws, whereas the jaws are connected to the rod by connecting plates pivotally attached to the outer surface of the jaws and the rod. Two-sided support arms are attached to the internal movable shaft. The upper section of the inner shaft is tapered and the circumference of the shaft includes a pressure spring, on the one end supported by the rod, and on the other by a removable lid. The spring-based latch mechanism can be released via a transversely-mounted trigger.

The device according to the invention allows for easy and clean collection, lifting and carrying of small items, in particular organic pieces such as animal droppings. The presented device allows the organic pieces/items to be collected without bending and without the need to use additional bags and containers. The presented device is easy to disassemble and maintain. The on-going maintenance can be done by simply rinsing it with water. The used jaws, springs and two-sides support arms combined with a handle and transverse trigger minimise the manual work required for the collection.

An embodiment of the object of the invention is presented in the figures, whereas Fig. 1 shows the front view of the open device, Fig. 2 shows the cross section of the device, Fig. 3 shows the axonometric view of the open device, Fig. 4 shows the front view of the closed device, Fig. 5 shows the cross section of the closed device, Fig. 6 shows the axonometric view of the closed device.

The device consists of a rod, jaw grabber and two-sided supports. Through a rod (1) which constitutes the outer body a movable shaft (2) is led, whose length is greater than the length of the rod, which constitutes an internal tube and whose one end is attached to a pin of a hinge (3) connecting the jaws (4) (cups), which are connected to the rod (1) by the arms (5) (connecting plates) pivotally attached to the outer surface of the jaws (4) and the rod (1). The upper end of the inner shaft is tapered (6) and includes a spring (7). The internal mechanism is based on a ratchet (10) finished with a transverse trigger (11). The end of the rod (1) is finished with a twist-off lid (8) which facilitates the maintenance and disassembly of the entire device. A handle (9) is attached to the lid. The arms (5) of the jaws (14) are pivotally connected to the movable inner shaft (2) and two-sided outer supports (12) finished with removable attachments (13).

The present grabber is suitable for grabbing both solid objects as well as semi-plastic items (all kinds of plasma and plastic materials). Grabbing of solid objects is facilitated by the ability to use the device in a vertical orientation. If the grabbing device is oriented slantwise, semi-plastic and plastic items can be easily collected - in this orientation the device functions as a shovel.

The cleaning and maintenance of the device are as easy as its operation. To disassemble the device for cleaning and maintenance, remove the handle located at the end of the device, which will allow the remaining components to be removed by pulling out the spring. The bottom part of the grabbing device can be pulled out by releasing the locking lever via the ratchet mechanism. To reinstall the inner pipe place it in the outer body, and the ratchet mechanism will locks the shaft in place. The remaining components: the external cups and connecting plates can be cleaned by simple rinsing with water.
