DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a foldable grip for mounting on an elongate object, such as the barrel of a portable weapon, and comprising an elongate grip section and a hinge for connecting the grip section to the elongate object. The grip in the folded-in position has a longitudinal direction which extends essentially parallel to the longitudinal direction of the object and in the folded-out position has a longitudinal direction which extends essentially at right angles out from the longitudinal direction of the elongate object.
BACKGROUND OF THE INVENTION
On portable weapons, for example, there is a need for grips which can be folded out in order to give the marksman better control over the weapon when firing. In this context, grips should not be mounted so that they are folded out permanently, since this makes it difficult to transport the weapon and increases the risks of the weapon being damaged or the marksman being injured during transportation. A known weapon design presently on the market has a foldable grip with a hinge which is in accordance with conventional hinge principles. For certain applications, however, this type of grip is clumsy and imprecise.
SUMMARY OF THE INVENTION
The object of the present invention is to make available a foldable grip which does not have the disadvantages mentioned above, is easy to maneuver between the folded-in position and the folded-out position,-and has precise positions both when folded out and folded in.
The object of the invention is achieved by means of a grip characterized in that the hinge comprises an oblique pin to be affixed on the elongate object and an oblique hole which is formed in the grip section and cooperates with the pin to effect an essentially 90 degree turn of the grip section around an axis in the longitudinal direction of the grip section during the movement of the grip between the folded-in position and the folded-out position. The oblique pin in combination with the oblique hole constitutes a hinge which can be made compact, and at the same time a well-defined movement process is obtained.
According to one advantageous embodiment, the pin and the hole are provided with locking shoulders for locking the grip in the folded-in and/or folded-out position. The locking shoulders give the hinge a well-defined folded-in position and folded-out position.
According to another advantageous embodiment, a spring element is arranged to act between the pin and the grip section. The choice of spring pretensioning defines the force which is needed for switching the grip section between the folded-in position and the folded-out position. The spring element is advantageously a helical spring.
To make the movement between the folded-in position and the folded-out position smooth, the pin and the grip section in yet another advantageous embodiment comprise sliding surfaces which face each other and cooperate directly.
According to an easy-to-grip and compact design, the grip section has an elongate shape transverse to the longitudinal direction of the grip section, which elongate shape relates to the hinge in such a way that the grip section in the folded-out position has a greater extent parallel to the longitudinal direction of the elongate object on which the grip is mounted than it has transverse to the longitudinal direction of the object. The elongate shape gives the handler a steady and comfortable grip when the grip is folded out and has the greater extent parallel to the longitudinal direction of the object. In the folded-in position, the grip lies with the lesser extent radially out from the longitudinal direction of the object. The grip extends out less from the elongate object and is therefore better protected during transportation and storage.
The invention will be described in greater detail hereinbelow on the basis of an example and with reference to the attached drawings, in which:
