DESCRIPTION:
BRIEF SUMMARY
The present invention concerns improvements in or relating to clamping arrangements, especially but not exclusively clamping arrangements for fixing one elongate member to another.
A number of ways are provided to fasten together tubing temporarily. For example the tubes can be fastened together by using rope and lashing appropriate length of the rope around the tubes. Alternatively, the tubes can be clamped together using clamps. Such clamps often have disadvantages that they can be used with only one size of tube and only in specific orientations.
According to one aspect of the invention there is provided a clamping arrangement comprising a reaction member, mounting means extending from the reaction member, a movable member mounted on and guided by the mounting means, the mounting means defining an engagement means spaced from the reaction member, and urging means operable via the reaction member to urge the movable member and the engagement means towards each other, whereby on placing an article between the movable member and the engagement means operation of the urging means causes the movable member to clamp the article between the movable member and the engagement member.
Preferably the engagement means is defined by a central region of the mounting means spaced from the reaction member. The mounting means may comprise a U-shaped member having the end regions thereof attached to the reaction member. Preferably, the mounting means comprises two of said U-shaped members arranged in alignment for an article to be received between the legs of each U-shaped member.
Preferably, the engagement means constitutes the central region of the or each U-shaped member. Each U-shaped member is conveniently in the form of a bar. The engagement means may be curved or substantially straight to correspond to the profile of the article.
The reaction member may comprise a substantially flat plate which may be of a substantially rectangular configuration, preferably substantially square. However, it will be appreciated that the flat plate can be of other suitable configuration. Where the reaction member is of a rectangular configuration, the mounting means is preferably attached thereto in the vicinity of the corners thereof.
The mounting means may be attached to the reaction member by welding or other suitable means of attachment such as by the use of an appropriate adhesive. Alternatively, the reaction member and the mounting means may be of integral construction formed together, for example by casting.
The reaction member may be so configured that the urging means extends therethrough. Preferably, the reaction member defines an aperture through which the urging means extends. The aperture may be provided with threads and the urging means may be provided with corresponding threads, whereby when the urging means is screwed into the reaction means to engage the engagement means, the engagement means is urged away from the reaction means.
The urging means is preferably in the form of a bolt which may be substantially L-shaped. It will be appreciated that the bolt can be of any other configuration or may be a bolt with a known hexagonal head, or may be an allen key bolt or other similar bolt.
The movable member preferably comprises a contact surface which is preferably appropriately configured to correspond to the configuration of the article. The contact surface preferably comprises raised regions and recesses between the raised regions to correspond to the configuration of the article. The raised regions may be substantially planar to engage a substantially planar surface on the article. The recesses may have a curved configuration to correspond to a curved surface on the article.
The movable member may define recesses or aperture s to receive the receiving means to enable the engagement member to be guided by the receiving means.
In a first embodiment of the invention, the mounting means is adapted to receive first and second articles which may be arranged substantially mutually orthogonal. Alternatively, the first and se
