DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a fastener means for fastening a first piece of cloth to a fixed support or backing or to a second piece of cloth. The fastener means is of a kind which comprises a first fastener member having an inner and an outer part and arranged to be attached to a first piece of cloth with the cloth clamped between a inner and outer parts, and a second fastener member attached to a fixed support or backing or to a second piece of cloth and arranged to co-act with the first fastener member. Each of the first and second fastener members has an opening and/or an outwardly projecting portion provided with a hook means, and the two fastener members can be snapped together in locking fashion by inserting the hook means into a corresponding opening and pivoting in a first sense the first fastener member relative to the second fastener member. It will be understood that the word "cloth" as used here and in the following includes all manner of fabrics, coverings and like materials.
In present day sailing craft, for example, the boom is protected by means of a boom cover or sleeve which is often held together by a zip-fastener or heavy-duty press studs. Press studs are also used to fasten and secure boom tents and other forms of boat covers. Zip-fasteners are relatively expensive, and their use can present difficulties, for example when the boom cover must be stretched in order to bring it around the boom and furled sail. The most serious drawbacks associated with the use of press studs are that they require the use of both hands when unfastening a boom cover for example, and that it is necessary to gather in the actual cover in order to manipulate the studs, which can place the cover material under great strain and increase the risk of damage when fastening the studs. Furthermore, there is nothing to prevent a conventional press stud from unfastening when the cover is unintentionally pulled or tugged.
SUMMARY OF THE INVENTION
Consequently, the prime object of the invention is to provide a fastener means of the kind described in the introduction with which, among other things, the aforesaid drawbacks are eliminated.
This object is realized by means of the invention, in that each of the fastener members attached to the cloth is provided with a lever arm which enables the fastener to be released without requiring the cloth to be pulled.
The fastener means according to the invention is characterized in that the outer part of the first fastener member comprises a gripping portion which serves as a lever arm and which is arranged, when pressed towards the second fastener member, to cause a pivot movement of the outer part in a second sense opposite the above mentioned first sense about a common abutment line lying between the fastener members to release the engagement between them, and that the hook means are arranged to prohibit a releasing pivot movement in the first sense.
When the fastener means according to the invention is intended to fasten together two pieces of cloth, as hereinbefore defined, for example a boom cover, the second fastener member is preferably identical to the first fastener member, and each of the outer parts of the members includes a gripping portion which serves as a lever arm, the gripping portions being arranged so as to enable them to be pressed toward one another, to disengage the two fastener members one from the other. In this case, the inner parts of each of the fastener members is provided with an opening and with an outwardly projecting part, the outwardly projecting part of one fastener member being arranged to be snapped into the opening of the second fastener member in locking fashion, while the corresponding outwardly projecting part of the second fastener member snaps into the opening in the first fastener member. When fastening together two flexible pieces of cloth, this fastener design will enable the fasteners to be released with the use of only one hand, without requiring the cloth to be gathered in or drawn.
