摘要:
The present invention relates to pruning shears, and is intended to cut off branches and stems of landscape trees, fruit trees, etc. while minimizing slips, etc. occurring during pruning when the branches or stems have large diameters or are stiff, to alleviate impacts applied to a hand of an operator particularly at the moment when thick branches or stems are cut off, and to be conveniently hung on a tree branch during work. Furthermore, the pruning shears have a rotating portable saw accommodation means configured to cut off a tree branch or stem outside the cutting range of the pruning shears.

The invention relates to a handle for a tool, for example a hammer, a screwdriver, a ladle, pliers, a knife or similar. According to the invention, said handle (1) is produced according to the interval-sandwich method for encasing, in a simple manner, the handle core (6) with a handle core covering (9), a soft layer (10) and an external layer (11). The handle core covering (9) and the outer layer (11) are made of a first material, whereas the soft layer (10) is made of a softer, second material.

An impact instrument for delivering an impulse to an object. The impact instrument may include an impact surface for contacting the object and an elongated member extending from the impact surface that terminates in an end. The elongated member may include a grasping region in the vicinity of the end. When the instrument is grasped within the grasping region, the center of percussion of the instrument preferably coincides with the impact surface. The instrument may also contain pivoting grasping member disposed on the elongated member. A cavity is preferably formed between the grasping member and the elongated member and may contain compressible material. The grasping member may rigidly contact the elongated member at an ideal pivot point. The grasping member is preferably adapted to pivot with respect to the elongated member at the ideal pivot point. The pivoting of the grasping member preferably increases the amount of impulse delivered to an object, decreases vibration experienced by the user of the instrument, and reduces counter-rotational forces imparted from the instrument to the user. The impact instrument may be a hammer, ax, golf club, tennis racket, or similar device.

A variable mass cap 20 for a shock imparting implement grip has a butt element 22 connected to a tubular portion 24 constructed to receive a selected mass 26, 28. The tubular portion 24 fits snugly within a recess 34 of a body 32, and is retained therein by the engagement of an annular ridge 36 with a first annular groove 30 disposed in an outer surface of the tubular portion 24. In an alternate embodiment, threaded portion 31 is received by and engaged by a corresponding threaded recess 34. The cap 20 is mechanically secured to the body 32 for providing a grip with a variable mass.

The invention relates to a handle (10) for a screwdriver or a screw clamp. The invention is characterized in that the handle (10), in the area of the handle exterior (18), is provided with soft plastic compartments (20) that extend in the longitudinal direction of the handle (10). Said compartments (20) can be configured as hollow compartments or can be filled with an elastic material. The possibly little remaining wall thickness of the outer area (23) allows to obtain a high elasticity of the handle (10) even when a relatively rigid material is used for the handle exterior (18), thereby allowing the handle (10) to adapt itself especially well to the hand of the user.
摘要:
A cover tape is disclosed to include an elongated base layer having an inner surface and an outer surface, and an elastic layer bonded to the inner surface of the base layer. The elastic layer is made of gel having a predetermined elasticity. When in use, the cover tape is wound around an object in a manner of that the elastic layer faces the object for enabling the outer surface of the base layer to be exposed to the outside for the user's grasp, thereby providing a soft, shock-absorbing function to the user.

A striking and pulling tool 1000, such as a hammer, having separable head elements 1020, 1040 secured to opposing sides of a handle 1002. The tool may be part of a system with interchangeable components.
摘要:
Element (1) with very high mechanical resistance and high vibration absorption, comprising at least one internal core (20) composed of at least one first material (2) having predominantly high mechanical characteristics, and united, through chemical bonding only, with at least one second material having predominantly highly elastic characteristics; the embodiment method consists in automatically uniting through chemical bonding a first material with predominantly high mechanical characteristics with at least a second material (3) with predominantly highly elastic characteristics in order to form a core (20) to be coated with at least a third material (11).
