  • Patent number: 8220240
    Abstract: A landscape care device has a first care tool embodied as a mowing device, a sweeping broom, or the like, and at least one second care tool in the form of a spring tine rake arranged in front of the first care tool and acting simultaneously or with time shift relative to the first care tool. A carriage with a front axle is provided, wherein only the spring tine rake is effective in front of the front axle of the carriage. The spring tine rake has spring tines and the spring line rake is designed such that the spring tines are effective by a substantially straight push movement exerted on the spring tine rake.

  • Patent number: 7891162
    Abstract: A quick connect tool assembly including a tool head having a socket therein, and an elongated pole for insertion into the socket tool head to lock the tool head and the pole together. The assembly includes a detent fixed to an end of the pole and teeth projecting into the interior of the socket on the tool head, such that the teeth engage the tool head detent to lock the pole to the tool head.

  • Patent number: 7299614
    Abstract: A novel rake minimally consists of: at least two tine frames, each tine frame having a plurality of tines coupled thereto; a tine frame coupling for coupling to proximal ends of each of the tine frames; pivot mechanisms coupled between the tine frames and the tine frame coupling; a rake handle coupled at a proximal end to the tine frame coupling, and adapted for being grasped at a distal end for raking activity; and a locking mechanism adapted to lock the tine frames into an operational raking configuration, and adapted to unlock the tine frames for transition to a non-raking stowage configuration. When the tine frames are unlocked, the tine frames are adapted to have their distal ends pivoted toward the distal end of the rake handle into the stowage configuration with the distal ends of the tine frames being at least in close proximity of the rake handle.

  • Patent number: 6880318
    Abstract: A roof-raking device designed to safely and efficiently remove pine straw and leaf debris from roofs of houses. When attached to a lightweight telescopic or other long pole this device can be used by a person standing at ground level or on a ladder, eliminating the risk of climbing and walking on a pitched roof. Formed of a flexible, resilient material our rake-head is a one-piece injection molded device comprising a plurality of deeply curved, reinforced tines, a central housing support structure and a female flange fitting. The tines are of varying length, width, thickness and curve radius. When slight downward hand pressure is applied to the upper surface of a connecting pole the flexible self-adjusting tines form themselves evenly to any horizontal pitched roof surface, and when applied to a V-shaped roof angle where two roof planes meet, the tines flex and form themselves to both roof planes simultaneously.

  • Publication number: 20040187470
    Abstract: A rake device including an elongated stem having a main portion and a first end portion adjacent thereto, with the first end portion having a first end and being configured such that a first angle defined between the first end and the main portion is acute. The rake device further includes a rake head secured to the first end portion of the elongated stem, with the rake head being generally disposed in a first plane, such that the first plane and the main portion define an acute angle therebetween.
