Abstract
A component 1 (e.g. a gas burner nozzle) to be installed with a conventional tool 7 is provided with a recess 4 which receives a resilient member 5. When the tool 7 is engaged with the component 1 the resilient member 5 is compressed and provides a frictional force, by way of which the component 1 is retained in engagement with the tool 7 even when being located in position in a vertical direction with the tool 7 above the component 1. Such an arrangement will facilitate the location of the component in positions which are not readily accessible. <IMAGE>
Description
SPECIFICATION
Improvements in or relating to a component
The present invention relates to a component which is intended to be located in position using a tool adapted to co-operate with a part of the component. The invention relates more particularly to such a component which is intended to be located in a position which is difficult to reach or in a position where the component cannot be supported whilst being located in position using the tool.
It is generally well known that the ease with which components such as pins, bolts, screws and the like, can be located in position or removed depends on the accessibility of the position in which they are to be located or from which they are to be removed. When a component is to be located in a position which is not readily accessible by means of normal tools, special tools such as an extendable socket spanner may facilitate the positioning of the component. However, such tools do not always enable these difficulties to be avoided, in particular when the component concerned must be located in position by way of an axial movement with the tool positioned in alignment with the component.In this particular case it is a common problem that the component will fall out of the retaining tool or become disengaged therefrom due to the action of gravity pulling the component in a downward direction. It is also sometimes necessary to retain the component in a predetermined orientation when locating the component in position. This also proves particularly difficult when the position in which the component is to be located is not readily accessible.
Prior proposals aimed at providing a solution to these problems include special tools which are provided with gripping means such as a small chuck, within which the component may be gripped in order to prevent the component from falling out of the tool under the action of gravity. Such special tools also enable the components to be held in a particular orientation during insertion of the component in position. However, these special tools are usually expensive due to their limited commercial market.
The present invention seeks to provide a solution to the above-mentioned problems which is both simple to use and is relatively inexpensive.
According to one aspect of the present invention there is provided a component, said component comprising a portion of predetermined configuration adapted to co-operate with a tool provided with a correspondingly configured portion, said two portions being adapted to engage each other, said portion of predetermined configuration of the component being provided with a recess which receives a resilient member, part of which member projects out of said recess when the member is in a relaxed condition within the recess, said member serving to retain the component in engagement with the correspondingly configured portion of said tool during location of the component in position.
Preferably said portion of predetermined configuration of the component is an outer surface of the component, said outer surface being designed to be received within a bore provided in said tool, said bore constituting said correspondingly configured portion of said tool.
Conveniently said portion of predetermined configuration of the component forms the outer surface of a polygonal head of the component. Said head may be of hexagonal configuration.
Alternatively said portion of predetermined configuration of the component may be an inner surface of a bore provided in the component, said bore in the component being designed to receive said correspondingly configured portion of said tool.
Preferably said recess is in the form of an annular groove. Said groove may be of rectangular cross-section.
The resilient member may be in the form of a horseshoe-shaped element or ring which is formed from steel or from a plastics material or from a rubber material.
The horseshoe-shaped element or ring may be formed from spring steel or may be in the form of an O-ring.
Conveniently the resilient member is of circular cross-section.
The component may constitue a gas nozzle for a gas burner, such as is used in a domestic cooking appliance.
According to a second aspect of the present invention there is provided a method of locating a component in position, said component comprising a portion of predetermined configuration adapted to co-operate with a tool provided with a correspondingly configured portion, said portion of predetermined configuration of the component being provided with a recess adapted to receive a resilient member, part of which member projects out of said recess when the member is in a relaxed condition within the recess, said method comprising the step of placing said resilient member within said recess, engaging said portion of predetermined configuration of said component with said correspondingly configured portion of said tool, thus moving the resilient member against its inherent bias further into said recess, said resilient member serving to apply a frictional force to said component to retain said component in engagement with said tool, the method comprising the further steps of locating the component in a desired position using the tool and subse quently removing the tool from the component.
In order that the present invention may be more readily understood and so that further features thereof may be appreciated, the invention will now be described by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a side view of a component according to the present invention, with a part of the component shown in section; and
Figure 2 is a side view corresponding to figure 1, with the component located within a co-operating tool which is shown partially in section.
Referring to figure 1 of the drawings a component 1 comprises a hexagonal head 2 formed integrally with a circular-section threaded shank 3. An annular groove or recess 4 is provided in the outer, side surfaces of the head 2 and extends completely around the head 2. The groove 4 is of rectangular cross-section. The component 1 may, for example, be in the form of a bolt or in the form of a gas nozzle for a gas burner, such as is used in a domestic cooking appliance.
The groove 4 is designed to receive a resilient member 5. The resilient member 5 may be in the form of a horseshoe-shaped element of steel of circular crosssection, as illustrated in figure 1, or the steel may form a complete ring with the ends overlapping. The particular steel used to form the element may be a spring steel. Alternatively the member 5 may take the form of an O-ring formed, for example, from a rubber material , if such material is suitable for the specific application in which the component is intended to be used.
The member 5 may alternatively be formed from a plastics material. In this event the member 5 could take the form of a complete ring.
Figure 1 illustrates the component 1 with the member 5 located in the groove 4 when the member 5 is in a relaxed condition. It will be appreciated from figure 1 that the resilient member 5 is resiliently biassed to project radially outwardly from the groove 4 when in a relaxed condition. The member 5 may be elastically deformed against the bias in a radially inward direction.
Figure 2 illustrates the component 1 located within a bore 6 of a co-operating tool 7. The tool 7 may be a conventional socket spanner or similar tool provided with a bore 6 whose configuration corresponds to the configuration of the outer surfaces of the head 2 of the component 1. Thus, the tool 7 has a bore 6 which is of hexagonal internal configuration and which is dimensioned snugly to receive the head 2 of the component 1 as illustrated in figure 2.
It will be appreciated that upon insertion of the component as illustrated in figure 1 into the tool 7 shown in figure 2 the resilient member 5 will be conzpressed into the groove 4 in a radially inward direction. The inherent resilience of the material from which the member 5 is formed will cause the member 5 to be biassed radially outwardly into engagement with the internal surfaced of the bore 6 within the tool 7. A frictional force is created at the point of contact of the member 5 with the internal surfaces of the bore 6 and this force effectively acts vertically upwardly in figure 2 and is greater than the downwardly acting force of the weight of the component 1, such that the component 1 is retained within the bore 6 against the action of gravity.
With the component retained within the bore 6 of the tool 7 the component may now be located in a desired position. When the component has been located in position, for example, by screwing into place in the case of the bolt illustrated in figures 1 and 2, the tool 7 may be removed from the head 2 of the component 1 simply by pulling the tool 7 away from the head 2. The member 5 and the groove 4 are designed such that the fr ictional force between the member 5 and the internal surfaces of the bore 6 may be overcome with a firm pull on the tool 7 in order to remove the tool from the head 2.
It will be appreciated that the present invention is not restricted solely to the specific embodiment described above, but that numerous modifications and alterations may be made to this design. For example, the design may be adapted for use in connection with a bolt provided with an internal bore provided within the head of a bolt, with the groove 4 being located within the internal bore in the head of the bolt. In this case the tool 7 would be provided with a projection of a configuration corresponding to that of the bore in the head of the bolt so that the projection may be received within the bore. Thus the tool 7 might be an Allen key. The resilient member in such an embodiment is resiliently biassed radially inwardly into the bore, and is moved radially outwardly when the tool is engaged with the component.
Further modifications may, of course, be made within the scope of the invention, for example, the invention may be applied to a component such as a nail, which is to be driven linearly without rotation.
