DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a device intended for attachment to the outer surface of a cylindrical object.
DESCRIPTION OF THE BACKGROUND ART
There is often found a need to secure articles to and/or hang articles on tubular or rod-like cylindrical objects. The word cylindrical as used here shall be interpreted in its widest meaning, and can be understood to refer to any configuration from triangular, square and pentagonal to a multi-sided, circular-cylindrical, elliptical, pear-shaped or irregular shape. In the case of leisure boats for instance, it is sometimes desired to attach articles to the pulpit of the boat or vessel, or to the guard rail supports or stanchions attached thereto. This applies to both the horizontal and vertical parts of the pulpite and also to other parts thereof. For instance, it is sometimes desired to attach to the pulpit a flag pole holder. Similarly, there is a need in shops which sell wearing apparel to attach elements to tubular stands from which clothes, garments, etc. are normally hung. It is also necessary to be able to connect the tubular members of tubular stands and like structures together when erecting such stands.
To such ends there have been proposed fastener devices which include a conical sleeve or socket which is locked firmly with the aid of conical wedge means. One such device is disclosed in GB 1 241 455. It consists of a conical outer sleeve and an inner sleeve comprising a ring with protruding strip-like axially directed conical wedge means and is intended to be mounted at an arbitrary position on a round shaft. One drawback with fastener devices of this kind is that the sleeve must be fitted from one end of the rod or tubular member, which is not always possible or desirable. In the device of GB 1 241 455 the outer sleeve may have a narrow axial slot, but said outer sleeve is so rigid that it is not possible to widen it so much that it can slip off the shaft side-ways. Furthermore, the wedge means of the inner sleeve exhibit protrusions at their ends such that the outer sleeve can not be removed from the inner sleeve, when the device is mounted an a shaft.
Consequently, in order to enable attachements to be fitted from the side of the rod or tubular member, there have been proposed devices in which a sleeve is provided with an axially extending side opening and a screw for clamping the sleeve in position. One drawback with devices of this kind is that they are unnecessarily bulky and the outwardly projecting screws present obstacles on which things can be caught and snagged. Furthermore, such clamping screws will either afford a poor attachment, with the risk of the sleeve sliding along the rod or tubular member, or will dig into the rod or tubular member and cause indents, scratches and/or outwardly projecting burrs thereon, which cannot always be accepted.
U.S. Pat. No. 2 136 861 describes a fastening device intended to be mounted on the end of a pump-rod for an oil well. It comprises an outer sleeve or body with a tapered bore and a longitudinal slot and a tapered split sleeve with a wedge-shaped rib opposite its slot and an annular groove for a lock ring at its reduced end. The split inner sleeve exhibits a substantially U-shaped opening or slot with a circular bottom portion and tangentially adjoining substantially parallel or slightly diverging sides. The outer sleeve exhibits at its wide end a yoke for connection to a pump jack or similar device. The inner sleeve is obviously made of metal or some other material which is only slightly elastic in order to be able to take up the great forces applied in oil pumping.
For mounting of the device, the inner sleeve is first positioned on the end of a pump rod with an enlargement at said end and then the outer sleeve is laterally adapted to the rod and moved endwise thereof to bring the inner sleeve in seating engagement with the bore, the rib of the inner sleeve being keyed in the slot of the outer sleeve, for example, the slots of the sleeves will be positioned opposite each ot
