BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a device for a clearing saw harness worn by a person such that the weight of a clearing saw detachably mounted to the harness and operated by said person will be transmitted to the body of said person, the harness being connected with, on one hand, a pad which is intended to bear against the hip or thigh of the person and to absorb compressive and torsional forces transmitted to the person from the clearing saw and, on the other hand, an attachment means which is disposed adjacent to the pad, to which attachment means the clearing saw is intended to be detachably connected.
PRIOR ART
Devices of the above-mentioned kind are previously known from the Swedish patent application as published for opposition 458 820 and the Swedish registered design 16228.
While these devices are satisfactory in most ways, vibrations and bumps spread from the clearing saw to the person wearing the harness, causing inconvenience or discomfort. Vibrations and bumps spread to the user's hands and arms are particularly troublesome and might even cause permanent damage when the clearing work is of long duration. Further, heavy bumps caused by, for instance, the clearing saw striking against objects of some size or by the user moving rapidly may bring the clearing saw out of engagement with the attachment means usually formed as a hook, which might have serious consequences and could cause the harness to be exposed to instantaneous stresses transmitted as blows to the shoulders of the user.
A device of the above-mentioned kind is also known from the Swedish patent application 8903644-6. However, it includes a resilient element which is attached to the pad and carries the attachment means (the hook). To some extent, said element solves the problem arising in the use of the two devices described above as regards transmission of blows, bumps and vibrations from the clearing saw to the user, but the device has certain disadvantages. The resilient element is a rubber plate whose resilience properties are such that, to a certain degree, it will stretch when a clearing saw is attached to the hook but is unable to stretch further to any great extent when the saw is rapidly removed from the plate. Further, the hook is attached to the rubber plate in such a way that, should the rubber plate break, the saw might accidentally be removed (might fall) from the pad, so that the user might be seriously injured. Further, the rubber plate is not protected against damage.
Also, the above described known devices have in common that their pads are expensive to manufacture and that they do not bear comfortably against the user which is mainly due to the parts bearing against the user not being sufficiently yielding.
SUMMARY OF THE INVENTION
It is an object of the present invention to improve previously known devices in the above described respects and to provide a device which is reliable and comfortable as well as easy and non-expensive to mount.
This object is achieved by the device according to the invention presenting the features stated in the characterizing portions of the claims.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a clearing saw harness provided with a device according to the invention,
FIG. 2 is a partly cut view of the device in FIG. 1, seen from the rear, and
FIG. 3 is a section along the line A--A in FIG. 2.
PREFERRED EMBODIMENT
A clearing saw harness, generally indicated at 1, is worn by a person P. The harness 1 includes a V-shaped portion 2 bearing against the person's back, and elongated parts 3 and 4 which are integral with said portion and which bear against the shoulders and chest of the user. At the free ends of the parts 3, 4, plates 5 and 6 are detachably and adjustably attached. The plates 5 and 6 are detachably interconnected at 7. The details 2-7 are formed of a flexible plastic material.
A first flexible band 8 is attached to portion 2, the band partially extending around the body of the user for fixing in a connection lock 9. A second flexible b
