The present invention relates to a tool and, particularly, to a tool adapted to be driven rapidly.
In order to allow a user to use an open end wrench without having to reposition the wrench on an object to be driven after each turn, TW Patent No. M483145 discloses a ratchet type open end wrench. The wrench has a body. The body has a grip and a head connected to the grip. The head has a first jaw and a second jaw for holding an object to be driven. The first jaw has a slot and a pawl is movably engaged in the slot. The pawl is urged by a spring. The pawl is not moved in the slot when the wrench turns the object. The pawl is, however, movable in the slot to a retracted position to allow the wrench to rotate relative to the object.
The wrench has a complicated structure. Thus, it is difficult to make the wrench, and it has a high cost. Further, the pawl is often stuck, especially after a long period of use.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
According to the present invention, a tool adapted to be driven rapidly includes a driving portion which has a first jaw and a second jaw configured to hold an object to be driven therebetween and an opening between the first and the second jaws configured to receive the object to be driven. The first and the second jaws have first and second engaging sides configured to grip the object to be driven. The opening has a closed end, an open end, and two opposite sides respectively delimited by the first and the second engaging sides. The first engaging side extends along a linear line. The second engaging side extends along a curved line. The closed end of the opening has a width smaller than a width of the open end of the opening.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure. The abstract is neither intended to define the invention, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
Other objectives, advantages, and new features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanied drawings.
The tool 10 has a driving portion. The driving portion has a jaw 30 and a jaw 40 configured to hold an object to be driven therebetween. The driving portion has an opening 20 between the jaws 30 and 40 configured to receive the object to be driven.
The jaws 30 and 40 have engaging sides 31 and 41 configured to grip the object to be driven. The engaging sides 31 and 41 are formed in one piece. The opening 20 has a closed end, an open end, and two opposite sides respectively delimited by the engaging sides 31 and 41. The closed end of the opening 20 has a width smaller than a width of the open end of the opening 20. Each of the engaging sides 31 and 41 has a first end adjacent to the closed end of the opening 20 and a second end adjacent to the open end of the opening 20. The first ends of the engaging sides 31 and 41 are spaced at a first perpendicular distance measuring a width W1. The second ends of the engaging sides 31 and 41 are spaced at a perpendicular distance measuring a width W2. The width W1 is smaller than the width W2.
The engaging side 31 extends along a linear line P1. The engaging side 41 extends along a curved line P2. The engaging side 41 extends along a parabola. The parabola has an axis of symmetry X which is perpendicular to the engaging side 31. The parabola has a vertex on an arbitrary axis Y which is parallel to the engaging side 31. The parabola has an equation:
y2=−12x.
The tool 10 can be operated in a first direction to turn relative to the object and a second direction to drive the object. When the tool 10 is used to drive the object, the object is in static with respect to the engaging sides 31 and 41.
Further, the body 50a defines a groove 52a and the body 60a has a connecting portion 61a movably engaged in the groove 52a. The body 60a is operably movable between a first position in which the connecting portion 61a is disposed adjacent to a first end of the groove 52a and the jaws 30a and 40a are disposed adjacent to each other such that the opening has a first size, and a second position in which the connecting portion 61a is disposed adjacent to a second end of the groove 52a and the jaws 30a and 40a are disposed away from each other such that the opening has a second size which is greater than the first size. The connecting portion 61a is engaged with a fastener 62a. The connecting portion 61a is prevented from moving out of the groove 52a by the fastener 62a. The fastener 62a is disposed outside the groove 52a.
Further, the body 50b has a position retaining portion 53b and the body 60b includes a catch 63b coupled thereto movably engaged with the position retaining portion 53b. The catch 63b is operably movable between a first position engaging with the position retaining portion 53b such that the body 60b is unmovably fixed to the body 50b, and a second position disengaging form the position retaining portion 53b such that the body 60b is movably disposed on the body 50b. The position retaining portion 53b includes a plurality of teeth on which the catch 63b is adapted to engage.
Further, the body 50c defines a groove 52c and the body 60c has a connecting portion 61c movably engaged in the groove 52c. The second body 60c is operably movable between a first position in which the connecting portion 61c is disposed adjacent to a first end of the groove 52c and the jaws 30c and 40c are disposed adjacent to each other such that the opening has a first size, and a second position in which the connecting portion 61c is disposed adjacent to a second end of the groove 52c and the jaws 30c and 40c are disposed away from each other such that the opening has a second size which is greater than the first size.
In the embodiment, each of the protrusions 33d, 35d, and 37d has sides configured to abut against the object to be driven, so a user can drive the object with a larger torque.
In view of the forgoing, the tools 10, 10a, 10b, 10c, 10d, and 10e, which is adapted to be driven rapidly, include the engaging sides 31, 31a, and 31b extending along a linear line P1, the engaging sides 41 and 41e extending along a curved line P2, and the closed ends of the openings 20, 20d, and 20e having a width smaller than a width of the open ends of the opening 20, 20d, and 20e.
The foregoing is merely illustrative of the principles of this invention and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention.
