Embodiments of the invention described herein pertain to the field of wrenches. More particularly, but not by way of limitation, one or more embodiments of the invention enable a multi wrench with fasteners such as spanners, sockets, ratchet sockets and nested fasteners.
Multi wrenches allow turning of nuts or bolts without having to carry many individual fasteners. Though prior inventions have incorporated multiple fasteners and have commercial success, there has been a continuing need for improvement. Such improvement consists of optimizing the combination of the functions and properties of such multi wrenches. These functions and properties include: minimization of weight, ease of use, ease of changing or engaging individual fastener, not losing the individual fasteners, and having clear vision of the operating fastener.
The present invention overcomes all the problems mentioned above and adds the advantage of being able to pack a lot of fasteners.
Fasteners share a common handle and are rotationally coupled around the circumference of at least one end of the handle. Individual fasteners are easily engaged by being manually rotated to the desired position. They are rotationally coupled to the jaws of the multi wrench so they will not get lost. Furthermore, there are many operational positions for best comfortable use, with some positions giving best clear vision of operation. The multi wrench weighs less because of the use of one common handle, and because fasteners include only the fastening part.
Another variation of the present invention is the use of a frame. Fasteners are rotationally coupled around the circumference of the frame. The frame has a hole or stud to engage the stud or hole of a conventional handle.
Not only the present invention overcomes all disadvantages other inventions have, but adds the advantage of being able to pack a lot of fasteners: Having nested fasteners at the circumference of the frame or end of handle; increasing the size of the circumference of the frame or end of handle; and having another hole or stud in the middle of frame or end of handle to engage more conventional fasteners.
The above and other aspects, features and advantages of the invention will be more apparent from the following more particular description thereof, presented in conjunction with the following drawings wherein:
The multi wrench will now be described using exemplary embodiments of the invention. It will be apparent to an ordinary skilled in the art person that the present invention may be practiced without incorporating all its aspects herein. Readers should note that although examples of the invention are set forth herein, the claims, and the full scope of any equivalents, are what define the metes and bounds of the inventions
Many jaws are coupled around the circumference of end 9 of handle 1. Ratchet socket 2 is in inward axial position toward handle 1, or home position. Ratchet socket 2 is rotationally coupled to jaws 7.1 and can operate bolt 2.1, but with limited view since the view is blocked by handle 1.
Fastener 3 is rotationally coupled to jaws 7.2 and is in home position. It also can operate on a bolt or nut but with limited view since it is blocked by handle 1.
Fastener 4 is rotationally coupled to jaws 7.3 and is in inward radial position. In this position, fastener 4 can operate on a bolt 4.1, but with limited view, since the view is blocked by end 9 and handle 1.
Spanner 5 is rotationally coupled to jaws 7.4. Spanner 5 is being manually rotated in direction 5.2 from home position to outward axial position of handle 1. This position is an operational position. Spanner 5 has a clear view of operation on bolt 5.1.
Nested fasteners 6 and 6.1 have the inner fastener being a spanner 6.1 and outer fastener being a socket 6. Spanner 6.1 is rotationally coupled to jaws 7.6, and socket 6 is rotationally coupled to jaws 7.5 and jaws 7.6 at its open section 6.2. Jaws 7.6 are added to give strength to nested fasteners 6 and 6.1.
Hole 8 is positioned on front of end 9 of handle 1 and in between all jaws, and can further engage a stud of a conventional fastener.
Many tools are rotationally coupled to many jaws which are coupled around the circumference of frame 16.
Spanner 13 is in outward position from handle 10 but with some angle 16 which facilitate its use in comfortable operation position, and at the time still provide clear vision.
Frame 16 has in between all the jaws a hole 12 which accommodates a stud 11 of a conventional handle 10.
Many tools are rotationally coupled to many jaws which are coupled around the circumference of frame 26.
Socket 23 is an outer fastener and is in position to operate with a clear vision.
Spanner 24 in a radial outward position and can operate on a bolt or a nut with a clear vision.
Stud 22 engages hole 21 of a conventional handle 20.
Teeth 30 on the hinged part of socket 33, ball 32 and spring 31 form a locking mechanism on many positions of socket 33.
In this example, three nested sockets are shown. The inner 51 is rotationally coupled to jaws 54. While outer sockets 52 and 53 are rotationally coupled to jaws 54 at their open section 50.2 and 50.3 respectively.
Teeth 60 in the hinged part of spanner 62, give more strength to socket 61 when the later is in operation position as shown in
Tools 82 and 86 are rotationally coupled respectively to jaws 81.1 and 81.2 which are coupled to frame 80.
Stud 83 is coupled to side 80.2 in between all jaws. Stud 83 engages hole 85 of a conventional handle 84. While hole 88 is positioned between all jaws on the other side 80.1. Hole 86 engages stud 87 of a conventional fastener 89.
Tools 92 and 96 are rotationally coupled respectively to jaws 91.1 and 91.2 which are coupled to frame 90.
Stud 93 is coupled to side 90.1 in between all jaws. Stud 93 engages hole 95 of a conventional handle 94. While stud 98 is coupled to the other side 90.2 in between all jaws. Stud 98 engages hole 97 of a conventional fastener 99.
Stud 93 is coupled to first side 90.2, and engages hole 95 of a conventional handle 94. While stud 96 is coupled to side 90.2, and engages hole 97 of a conventional fastener 99.
Tools 102 and 106 are rotationally coupled respectively to jaws 101.1 and 101.2 which are coupled to frame 100.
Hole 103 is positioned inside side 100.1 in between all jaws. Hole 103 engages stud 105 of a conventional handle 104. While hole 108 is positioned on the other side 100.2 in between all jaws. Hole 108 engages stud 107 of a conventional fastener 109.
