The present invention relates to display brackets for a wrench, more particularly to a display bracket for a wrench that achieves the purpose of economizing exhibition space and has a simple structure.
A display bracket for a wrench of the prior art, such as the “display bracket for a wrench with flexibility damping” disclosed by Taiwan patent number 541922, is characterized by a flexible part attached to a hexagonal mount and a locking hole on a display plate. The flexible part provides a resistant torque when a wrench connected to the mount is rotating the hexagonal mount, whereby the rotational angle of the mount can be known. However, the conventional display bracket has the disadvantages that the rotational angle of the mount cannot be precisely recognized and that the flexible part is not durable. As the flexible part is experiencing a fatigue, the resistant torque soon disappears.
The “tool bracket” disclosed by Taiwan patent number 434659 comprises a main body having an annularly arranged deflected portion equipped with teeth and a set of annularly arranged teeth on a sound board, whereby the engagement between the deflected portion and the sound board will create a sound indicating the angular displacement of a tool on the main body with respect to the main body.
However, a display bracket using a sound board of the prior art has two sets of teeth each on the sound board and the deflected portion of the main body, which makes the bracket too complicated to build and therefore increases the production cost.
The “wrench display bracket” disclosed by Taiwan patent number 542078 is provided with a hanger post attached onto a planar body at a predetermined location by screwed parts or an adhesive material. The hanger post has a flexible plate extended from the outer rim thereof. The hanger post is further provided with a retaining hole or slot for securing a hexagonal nut, whereby, as the wrench is rotated against the planar body, the engagement of a set of teeth within the nut to the hanger post will produce a repetitious jump feeling and sounds so as to recognizing the rotational angle.
However, the “wrench display bracket” disclosed by Taiwan patent number 542078 has the following disadvantage.
The effects of recognizing angle are produced in a combination of a hanger planar body, a hanger post and a nut. The combination further includes a flexible plate extended from the outer rim of the post, whereby, as the wrench is rotated against the planar body, the engagement between a set of teeth within the nut and the flexible plate of the hanger post will produce a repetitious jump feeling and sounds so as to recognizing the rotational angle. However, the structure is still too complicated.
Accordingly the primary objective of the present invention is to provide a display bracket for a wrench that can economize exhibition space. The display bracket for a wrench comprises only a main body and a mount. The main body is provided with a through locking hole at a predetermined location thereon. The locking hole further includes a pair of symmetric, parallel slots of predetermined depth in a horizontal direction straddling the locking hole on the main body. A flexible piece is formed between the symmetric slots. The mount consists of an engaging portion with a polygonal circumference and a cylindrical connecting member. The cylindrical connecting member of the mount is capable of being connected to the locking hole, whereby a plurality of arced projections around the member and the main body can be engaged.
The display bracket for a wrench of the present invention thus has a simpler structure. The angular displacement of the mount with respect to the main body can still be recognized by a repetitious jump feeling and sounds, which are produced by the interaction between an annular ratchet and a flexible piece on a dial on the main body.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings.

The display bracket for a wrench further comprises a mount 20 capable of being connected to the locking hole 13. The mount consists of an engaging portion 21 with a hexagonal circumference and a cylindrical connecting member 22. The interface between the engaging portion 21 and the connecting member 22 forms a dial 23. There is a triangular pointer 231 located at the outer rim of the dial 23; the pointer 231 will move the rotation of the mount 20.
Further, the hollow, cylindrical connecting member 22 is provided with two perpendicular notches on a bottom side thereof for a flexible compression of the connecting member 22. The end of the connecting member 22 close to the dial 23 is provided with a ratchet 221 composed of a multitude of continuous oblique teeth surrounding the ratchet 221. When the connecting member 22 is inserted into the locking hole 13, the pointed portion 161 of the flexible piece 16 can be engaged with the ratchet 221, thereby the flexible piece 16 will go through a transverse jump across the symmetric slots 15 and will produce a sound by the jump of the pointed portion 161 against the ratchet 221. There are 4 arced projections 222 formed on the outer surface at the rear end of the connecting member 22 of the mount 20 for securing on the flange A when the mount is inserted into the main body.

As shown in
Moreover, the middle bulged section of the retaining plate 40 may provide the ratchet wrench 30 with a left angle pre-setter and a right angle pre-setter so that a range of angular displacement can be set. Referring to
The present invention is characterized by combining the main body 10 and the mount 20 to achieve the function of displaying a wrench. It is another advantage of the present invention that the sounds created as the mount 20 is rotated against the main body 10 help the user to recognize the exact angular displacement. Instead of the conventional design of complicated tooth structures on both of the main body 10 and the mount 20, the ratchet 221 of the connecting member 22 can creates the same rattling audio effect when it is connected to the locking hole 13; this is achieved by the flexible piece 16 formed between the symmetric slots 15. The present invention revolutionizes the old concept of two engaging annular tooth structures on both of the mount and the main body, indeed achieving a structural simplicity.
Referring to
Accordingly, the mount 20a of the second preferred embodiment comprises an engaging portion 21a taking the shape of a hexagonal nut, a cylindrical connecting member 22a and a dial 23a. The difference of the second preferred embodiment is that the hexagonal engaging portion 21a is a hollow body; the dial 23a and the pointer 231a are outwardly extended from a bottom end of the engaging portion 21a. On the other hand, the connecting member 22a is formed inside the bottom wall of the engaging portion 21a. A portion of the connecting member 22a is exposed outside the engaging portion 21a, which is further provided with 4 arced projections 222a, and a top end of the connecting member 22a is provided with a ratchet 221a therearound. Since the connecting member 22a and the engaging portion 21a is separated by a spacing C whose length is equal to the thickness of the wall of the flange A1, the connecting member 22a of the mount 20a can go through the main body 10 whereby the projections 222a at the top end of the connecting member 22a will engage mutually, and, at the same time, the ratchet 221a surrounding the connecting member 22a will engage with the flexible piece 16 of the main body 10.

The present invention is thus described, and it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
