Definitions

  • the invention relates to a hand tool for gripping lying on the ground soft gripping material, such as feces and the like, especially dog feces, consisting of a manually operable, gripping arms having gripper.
  • the gripper consists of a pair of rod-shaped gripping arms, which can be moved by means of a manually operable control head between an open and a closed position.
  • a hand-held device For example, objects falling apart can not be picked up with such a hand-held device.
  • the object of the invention is therefore to provide a hand-held device which is also suitable for collecting soft, so fragile gripping.
  • the object to be read-in is completely grasped by the opened bag opening and can be transported into the interior of the bag. It can therefore only loose coherent or multi-part objects, which may also be still moist, are eliminated.
  • the feces can be packaged odorless and disposed of at a suitable location.
  • the elimination of feces or other unpleasant objects is thus considerably simplified, especially since the hand-held device according to the invention can be carried along in a convenient manner and therefore is always available when needed.
  • the elimination of animal feces on public facilities is therefore easy, which will contribute significantly to their purity.
  • the grippers are opened in the rest position of the hand-held device. Without action by the operator, the gripping arms are open, so that the user of the handset can pick up the gripping material directly without first to open the gripping arms or hold a lever pressed, which allows the open position of the gripping arms. As a result, the handling is particularly simplified. The comfort for the user is significantly increased.
  • the gripping arms are held by a spring in its open position.
  • the spring may be formed as a compression or tension spring.
  • the spring may either be positioned directly between the individual gripping arms or may be mounted between the gripping arms and the wand of the handset.
  • it can also be provided to displace the spring into the interior of the rod, so that the spring is not directly accessible. This protects it from damage and dirt.
  • a further guide element can also be provided between the gripping arms and the spring in order to optimally transmit the force of the spring to the gripping arms.
  • a fixation of the gripper is possible at least in the closed position.
  • fix the gripper or its gripping arms in any position.
  • the user can easily pull the bag containing the gripping material on the gripping arms. He has both hands free to close the bag, as he does not have to hold the gripping arms in a certain position.
  • a detent is provided on the operating head or on the rod of the hand-held device with which an operating arm of the hand-held device is held.
  • the gripping arms are fixed in position.
  • a button so as to release an adjusting means, in particular a arranged between the operating arm or operating head of the handset and the gripper arms wire, so that the gripping arms are opened.
  • a holding element is provided on the handset, which engages in a recess on the rod or operating head, so that the gripper is fixed in its position.
  • the holding element may be formed, for example, as a bolt or the like.
  • the bolt can engage in a groove of an operating lever when the operating lever is in a certain position. In this position, the operating lever is then held, which has the consequence that also held in operative connection with the operating lever gripper and its gripper arms are held in position.
  • the bolt-shaped retaining element may for example be guided in a slot, so that in the normal position of the handset, ie with the gripper directed to the ground, the bolt automatically falls into the groove of the control lever by gravity.
  • the adjusting element between the gripping arms and the operating head in particular the drawstring or the puller wire, a locking element such as a bolt, which can be latched or suspended in a recess in the rod.
  • the pull cord can be released by a pressure on the locking element or the bolt, so that the gripping arms move automatically into their rest position.
  • the gripping arms are preferably pulled by a spring or a resilient element in the open position.
  • a possible form of locking can also be a simple eyelet, which is arranged on the rod.
  • an operating arm of the operating head can be hooked into the eyelet.
  • alternative embodiments, such as clamping or locking closures for holding the pull cord or a locking lever or the like are possible.
  • the handset has two gripping arms made of a wire that is substantially triangular in shape.
  • the base leg of the triangle of the gripper arm is substantially perpendicular to the rod of the handset. In the closed position of the two gripping arms, the two base legs of the gripper arms are parallel to each other. A positioned between the two gripping arms bag is closed in the closed position of the gripping arms, so that picked up in the bag gripping material can not fall out.
  • the two side legs of the triangular gripping arms are curved so that they essentially describe a quarter circle.
  • a first portion of the side legs may be perpendicular to the base leg.
  • the first section is followed by a second curved section, which also describes approximately a quarter circle or a third circle.
  • the curvature of the side legs is formed so that it is substantially perpendicular to the base leg.
  • the gripping material can protrude between the side legs and the base leg.
  • the receiving space for the gripping goods is essentially determined by the volume of the bag and not by the shape of the gripping arms.
  • the hand-held device for gripping and collecting feces lying on the floor and the like, in particular dog feces, essentially consists of a control head 1, which is arranged at one end of a bar 2, FIGS. 1a, 1b. At its other end sits a gripper 3, e.g. in the form of a clamp, which is connected via an adjusting means 4, such as wire or the like, with the operating head 1.

  • the operating head 1 likewise has a housing 5 which is mounted on the rod and in which an angle lever 6 with a downwardly pointing operating arm 6 'and an actuating arm 6 "projecting beyond the actuating means 4 and pivotably mounted about a bolt 7 is mounted Adjustment means 4 in turn is connected at the other end to two opposing gripping arms 8, so that they are pivoted against each other in an applied train around joints 9.
  • Springs 10 hold the gripping arms 8 in their illustrated open position
  • the springs 10 are supported at the other end on a rod 2 plugged bearing housing 11, in which the joints are mounted 9. It can be seen that Pivoting the angle lever 6 in the clockwise direction, the two gripping arms 8 are pivoted against each other in the closed position.
  • a bag 13 is formed of plastic film or similar material.
  • the material is preferably flexible and / or made of decomposable material.
  • the bag 13 can be inserted between the gripping arms 8 and pulled outside around the webs 12 in the form of a cuff 14. This results in a one-sided open cavity, with the directed against the ground an object, e.g. a dog excrement, can be included.
  • the object is then received in the interior of the bag 13 and can be lifted from the ground.
  • the bag 13 can be closed by squeezing the opening and fed to further disposal. Here only need clean outer surfaces of the bag 13 are touched, so that a hand and equipment pollution is excluded.
  • the bag 13 is closed at its opening edge with a pull cord 15.
  • Other possibilities of bag closure may be provided, such as brackets or Velcro.
  • an eyelet 15 or the like may be arranged, in which the pressed-on operating arm 6 'is hooked to hold the gripping arms 8 closed.
  • a pull cord 16 may be provided at the opening edge of the bag 13 to contract it. This can also be replaced by a hook and loop fastener, a removable adhesive strip or the like.
  • the removal of the bag 13 from the gripping arms 8 can be further facilitated by rising from the ends of the webs 12 obliquely to gripping arm 8 supports 17, as shown in FIG. 3 can be seen.
  • the handling of the device can finally be simplified by convenient design of the housing 5 on the control head 1.
