Abstract
A wrench or spanner having a cavity where the walls of the cavity have a star shape with four internal 90 degree angles 1.1 alternating with four internal 120 degree angles 1.2, each angle defined by a pair of walls. The arrangement of the walls allows the wrench or spanner to engage with both square and hexagonal nuts and bolts. The wrench or spanner may be adjustable, using a ratchet, with an inner member 1.4 and an outer member 1.5 that separate along lines that are perpendicular to the handle 1.7 and parallel to the handle 1.8.
Description
Title:
Multifunctional ratcheting flare nut wrench Technical field:
Mechanical engineering Description:
The present invention comprises a ratcheting flare nut wrench which comprises an innovative ratcheting geometry which allows said wrench to be inserted onto workpieces which comprise both hexagonal and rectangular geometries in order to rotate these without needing to change the tool used, while simultaneously offering the possibility to ratchet and hence rotate said workpiece without needing to disinsert said tool from the workpiece.
Said geometry comprises four inner right angled geometries which project towards the outside of the insertion cavity for the rectangular shaped geometries, while simultaneously comprising two oppositely heading inner walls which are positioned at 120 degrees between each other on each side, and which project towards the outside of said ratcheting geometry and which can hence be used to insert said ratcheting geometry into hexagonal shaped geometries.
Figure 1 comprises a top view of one of the sides of the ratcheting flare nut wrench, showing the workpiece insertion cavity (1.6) between the two upper clamping members (1.4, 1.5).
The inner member (1.4) comprises the lower part of the insertion cavity (1.6), while the outer member (1.5) comprises the upper part of said insertion cavity (1.6). Said members separate at the middle of the two oppositely facing 90 degree inclined pairs of piles (1.1), hence separating along a horizontal line (1.7) which crosses along the middle of said cavity (1.4). The separation lines (1.7, 1.8) separate the two members (1.4, 1.5), with one separation line (1.7) being positioned along a horizontal line which projects horizontally form the edge of the inner member (1.4) to the middle edge of the outer 90 degree inclined profile pair (1.1) of the insertion cavity (1.6), while another separating line (1.8) projects vertically from the inner edge of the oppositely positioned 90 degree angled pair profile pair (1.1), which is positioned oppositely o the previously said pair of 90 degree inclined profiled pair (1.1).
The insertion cavity (1.6) is geometrised such that the inner walls (1.1, 1.2, 1.3) form a geometry which can accommodate both hexagonal and square fasteners. Said geometry is characterised by a set of four right angled inner wall profiles (1.1) which are each (1.1) positioned in front of another one of those (1.1) and which each projects away from the centre of said cavity (1.6). This hence shapes a four point star like geometry (1.1) with each of said right angled geometries (1.1) comprising a 90 degree right angle between the two inner walls of each of said geometries (1.1), such that each inner wall (1.1) projects in parallel to the other geometry’s inner wall (1.1), and perpendicularly to the inner walls (1.1) which are positioned on the other sides of the right angled geometries (1.1). This feature (1.1) therefore offers accommodation for a squared geometrised fastener. A flat wall (1.3) is positioned on each of the two sides of two oppositely facing 90 degree inner profiles (1.1), such that these (1.3) walls are exactly parallel to each other (1.3) and project oppositely to each other (1.3) while each being situated beside two of said 90 degree inner cavities (1.1), while these (1.3) face exactly oppositely to each other when comprised with the oppositely positioned geometry. Between said 90 degree angled inner profiles (1.1) and said flat walls (1.3), flat wall profiles (1.2) are comprised, which project at 120 degrees between the two wall profiles (1.2) which are between the two sides of said 90 degree inner cavities (1.1). Said set of 120 degree inclined inner wall profiles (1.2), are positioned oppositely to the other set of said wall profiles (1.2), therefore comprising two sets of said inner 120 degree inclined wall profiles (1.2) which are positioned opposite to each other (1.2).
So, said inner 120 degree inclined inner walls (1.2) are comprised of four inner walls (1.2). The same is comprised concerning the flat walls (1.3) which are positioned between said inner 90 degree angled wall profiles (1.1) an said inner 120 degree inclined inner walls (1.2). The inner profile of the closed cavity (1.6) therefore comprises four inner 90 degree angled wall profiles (1.1), which are each comprised of two walls (1.1), hence making up eight inner walls (1.1).
Said parallel projecting lined profiles (1.3), can either project perpendicularly or horizontally to the direction of projection of the handle (1.5) as well as its main separation line (1.8), depending on the requirements of the target customer users. However, a perpendicular projection to the handle (1.5) and separation line (1.8) would be the most suitable, as it would maximise the ease of insertion and disinsertion of the tool’s members (1.4, 1.5) from the workpiece while ratcheting. Figure 1 shows said lined profiles (1.3) projecting perpendicularly to said handle (1.5) and said main line separation (1.8).
The previously said geometries (1.1, 1.2, 1.3) can therefore comprise the inner geometries of the closed cavity (1.6), which is positioned through at least one end of the wrench’s handle (1.5).
Said novel geometry offers the advantage to the user of allowing the insertion of the closed end geometry(s) (1.6) of said wrench to both rectangular geometrised and hexagonal geometrised fasteners. Additionally, said design allows both square and hexagonal fastener geometries with the same inner fastening dimensions to be turned using the wrench concerned, by using the closed cavity (1.6) concerned.
Said novel geometry (1.1, 1.2, 1.3) can comprise a cap stop structure along the edges (1.1, 1.2, 1.3) of one side of said novel geometric cavity (1.6). This design offers the advantage that the spanner tool will not slip away from the workpiece or fastener.
Said ratcheting flare nut wrench can be manufactured using casting processes, preferably investment casting or sand casting processes, as well as forging processes, preferably using at least one forging press to shape said tool geometries, or injection moulding processes.
Said ratcheting flare nut wrench tool can be made of a polymer material such as PVC or polypropylene, or a metallic material, preferably and alloy, and most preferably titanium alloy or steel such as tool steel, high carbon steel or high strength steel.
Said ratcheting flare nut wrench’s insertion geometry (1.6) and contour (1.1, 1.2, 1.3) profiles can be comprised in any type of ratcheting flare nut wrench. The geometric cavity (1.6), comprising the specific profile contour arrangement (1.1, 1.2, 1.3) concerned, can be comprised in wrenches, adjustable wrenches, ratcheting wrenches, open and closed end wrenches, bi-closed end wrenches, cap stop equipped wrenches, socket wrenches, ratcheting flare nut wrenches, flare nut wrenches, combination wrenches, or any other type of wrench available.
So, the present invention comprises a ratcheting flare nut wrench which comprises an insertion cavity (1.6) which comprises four inner 90 degree angled flat wall geometries (1.1) with up to two flat inner walls each (1.1) and which form a cross-shaped profile based on said four geometries, as well as four geometric profiles (1.2) which are each comprised of two pairs (1.2) of inner flat 120 degree inclined walls (1.2), and which comprises two pairs (1.3) of two oppositely projecting parallel flat inner wall geometries (1.3) which unite said 120 degree inclined inner walls (1.2) to one of the pairs of inner walls (1.1) comprised in said inner 90 degree angled profiles (1.1), therefore comprising an inner geometric profile (1.6) inside which both square and hexagonal fastener geometries of the same inner fastener dimensions can insert, such that said parallel projecting lined profiles (1.3) project perpendicularly to the direction of projection of the handle (1.5) as well as its main separation line (1.8).
