Patent Application
20130042440
This application claims priority to Great Britain Application No. GB1013953.3 filed on Aug. 20, 2010, the entire connects of which are incorporated herein by reference.
The field of the invention relates to an attachment system, and more particularly to an attachment system for attaching a first object to a surface of a second object.
It is often necessary for one object to be attached to, or otherwise held in place relative to, a second object. In particular, it is often necessary for, say, a sheet of material such as a sheet of tarpaulin or the like to be attached to some supporting object, for example to provide shelter from the rain or wind. In order to attach such sheets to a supporting object, it is typically necessary to provide some form of attachment mechanism capable of being securely coupled to the sheet of tarpaulin, and capable of being securely coupled to the supporting object.
US2008104805 discloses an example of such an attachment mechanism, which comprises a clip body having first and second jaw members arranged to adjustably grip and release the sheet of, in this example, tarpaulin. The attachment mechanism of US2008104805 further comprises at least one further attachment fitting for engaging an article separate from the sheet material. Examples of such an at least one further attachment fitting taught in US2008104805 comprise: a hook portion for receiving a rope or cords: internal threads to engage threads provided on the article separate from the sheet material; a strap member for wrapping itself around articles, etc.
A problem with known attachment mechanisms, such as the example taught in US2008104805, is that they require the article to which the sheet material is to be secured to comprise an attachment feature, for example a rope or chord to engage with a hook, threads to engage with internal threads of the attachment mechanism, or simply something around which a strap member may be wrapped. However, it is often the case that such features may not be available, rendering such known attachment mechanisms ineffective.
Thus, there is a need for an improved method and apparatus for attaching a sheet of material to an article separate from the sheet of material.
Accordingly, the invention seeks to mitigate, alleviate or eliminate one or more of the abovementioned disadvantages singly or in any combination.
According to an aspect of the invention, there is provided an attachment system for attaching a first object to a surface of a second object. The attachment system comprises an attachment mechanism body comprising first and second jaw members arranged to grip and release the first object. The attachment system further comprises a suction cup arrangement, operably coupled to the attachment mechanism body and arranged to operably couple the attachment mechanism body to the surface of the second object by way of suction. The attachment mechanism body further comprises a grip adjustment mechanism for adjusting a distance between the first and second jaw members to enable the first and second jaw members to selectively grip and release the first object.
In this manner, the suction cup arrangement enables the attachment system to be affixed to the surface of an object, without the need for the object to which it is to be attached to comprise one or more attachment features.
In one optional embodiment of the invention, the grip adjustment mechanism may comprise a threaded shaft operably coupled to the first jaw member and arranged to extend through an aperture within the second jaw member and to engage with a retaining element comprising an internally threaded recess or aperture.
In one optional embodiment of the invention, the first and second jaw members may comprise engagement features on adjacent surfaces thereof. For example, the first and second jaw members may comprise teeth formations on adjacent surfaces thereof arranged to cooperate with one another.
In one optional embodiment of the invention, the first and second jaw members may comprise planar configurations, and are arranged to grip and release a first object comprising flexible sheet material.
In one optional embodiment of the invention, the first and second jaw members may comprise concave configurations, and are arranged to grip and release a first object comprising a cylindrical configuration.
In one optional embodiment of the invention, the attachment mechanism body may comprise a second aperture therethrough, and the suction cup arrangement comprises a threaded shaft operably coupled to a suction cup, and arranged to pass through the second aperture in the attachment mechanism body, and to be retained in place by way of a threaded nut.
These and other aspects, features and advantages of the invention will be apparent from, and elucidated with reference to, the embodiments described hereinafter.
Embodiments of the invention will be described, by way of example only, with reference to the accompanying drawings, in which:
Reference will now be made to preferred embodiments of the present invention with reference to examples illustrated in the accompanying drawings. However, it will be appreciated that the present invention is not limited to the specific illustrated examples.
Referring first to
Advantageously, the suction cup arrangement 140 enables the attachment system 100 to be affixed to the surface of an object, thereby overcoming the problem of prior art attachment systems requiring the object to which it is to be attached to comprise one or more attachment features, for example a rope or chord to engage with a hook, threaded elements, or simply something around which a strap member may be wrapped. Applications where it is advantageous to be able to attach objects to the surface(s) of another object may include, by way of example only, glass panes such as windows, vehicle body panels such as car doors, bonnets and/or roofs, the hull or deck of a boat, the sides of caravans and recreation vehicles, etc.
For the illustrated example, the attachment mechanism body 110 further comprises a grip adjustment mechanism 150 for adjusting a distance between the first and second jaw members 120, 130 to enable the first and second jaw members 120, 130 to selectively grip and release an object. In this manner, the first and second jaw members 120, 130 are able to grip objects comprising a range of thicknesses, and with adjustable pressure.
For the illustrated example, the grip adjustment mechanism 150 comprises a threaded shaft 125 operably coupled to the first jaw member 120 and arranged to extend through an aperture 135 within the second jaw member and to engage with a retaining element 155 comprising an internally threaded recess or aperture. In this manner, by rotating the retaining element 155 about the threaded shaft 125 in a first direction the threaded shaft 125 and the internally threaded recess/aperture of the retaining element 155 cooperate to move the retaining element 155 along the threaded shaft 125. For example, by rotating the retaining element 155 in, say, a clockwise direction, the retaining element 155 may be caused to move towards the first jaw member 120, thereby compelling the second jaw member 130 towards the first jaw member 120. Conversely, by rotating the retaining element 155 in the opposite direction, i.e. anti-clockwise, the retaining element 155 may be caused to move away from the first jaw member 120, allowing the second jaw member 130 to move away from the first jaw member 130.
In accordance with some embodiments of the present invention, the first and second jaw members 120, 130 may comprise engagement features on adjacent surfaces thereof, in order to more securely grip an object there between. For example, and as illustrated in
Suction cup arrangements are well known, and as such the suction cup arrangement 140 need not be described in greater detail in order to enable a skilled person to implement this feature of the present invention. However, for completeness, the attachment mechanism body 110 of the illustrated example comprises a second aperture 170 there through, and the suction cup arrangement 140 comprises a threaded shaft 180 operably coupled to a suction cup 145, and arranged to pass through the second aperture 170 in the attachment mechanism body 110, and to be retained in place by way of a threaded nut 185. For the illustrated example, a washer 190 is provided between threaded nut 185 and the attachment mechanism body 110. One example of a suitable suction cup arrangement is available from Adams Mfg Crop. (www.suctioncups.com), part number-83.
For the example illustrated in
For example, and as illustrated in
Although not illustrated, it is contemplated that, for the examples illustrated in
Although individual features may be included in different claims, these may possibly be advantageously combined, and the inclusion in different claims does not imply that a combination of features is not feasible and/or advantageous. Also, the inclusion of a feature in one category of claims does not imply a limitation to this category, but rather the feature may be equally applicable to other claim categories, as appropriate.
Furthermore, the order of features in the claims does not imply any specific order in which the features must be performed and in particular the order of individual steps in a method claim does not imply that the steps must be performed in this order. Rather, the steps may be performed in any suitable order. In addition, singular references do not exclude a plurality. Thus, references to ‘a’, ‘an’, ‘first’, ‘second’, etc. do not preclude a plurality.
Thus, examples of an attachment system have been described that may alleviate at least some of the shortcomings of past and present techniques and/or mechanisms.
