The present invention relates to the identification for wrench-type tools and in particular, to a color-coding system used in wrench-type tools. The color-coding system is used in specifics with wrenches in which one end is open and the opposite end contains a ratchet; one end is open and the other close; both ends are open; lastly, both ends are closed.
The conventional way of marking tools such a wrench consists of printing on its surface the size of the nut that is attached to the mouth of the key, as well as the name of the manufacturer (or logo). This printing can be carried out in different ways, for example, stamping, printing, molding (identifier included in the mold used to mold the tool), stickers, etc.
The previously mentioned conventional marking form has disadvantages in terms of ease in reading the type of tool; due to that the mark, in general, it is not easily visible because there is no contrast of the number with the background on which it is printed, that is, the body of the tool, since both the number and the tool are the same color and material, usually metallic; in addition, the number can be greased or smudged by dirt, which makes it difficult to read.
In working conditions that can be of reduced illumination, or when using lamps with great flash is even more difficult to read because the material of the tool reflects the light making it necessary to move the tool to find a point of contrast that allows its reading.
On the other hand, in the individual ratchet type tools, the direction of rotation to be used is not usually included, which causes the operator to have to turn the tool or manipulate it to find the direction for its correct use, which in return hinders its operation.
Currently, there are three types of keys with 15 fixed-mouth nuts. The first is called a ratchet.
The ratchet uses a method of reversible type, which changes direction by means of a selected lever, and allows to tighten in both directions according to the position of the selected lever.
The second type of key is called a mixed-mouth wrench combination and it is as shown in figure IB. This key is open at one end and closed at the other.
As mentioned above, the ratchet set can also have both ends open, or both ends closed.
The third type of key is fixed at one end with an open mouth and has a ratchet at the closed end of the tool. In this type of key, the ratchet is not reversible.
The present invention relates to a wrench with color coding. Again, there are four ways in which the wrench set can be made—one in which one end is open and the other end contains a ratchet, one end open and the opposite side closed, both ends open; and lastly, with both ends closed. The wrench uses a color-coding system for easy identification of the nut sizes that each key can manipulate.
The ratchet associated with the wrench is a mechanism that allows a nut or gear to turn into a single direction, while preventing you from doing so in the contrary; to perform this function of no rotation in the opposite direction, the ratchet makes use of teeth.
The ratchet allows you to use the tool to tighten (or to release) a nut without decoupling the tool from the nut, that is, once the nut is engaged. Since the ratchet is not reversible, the tool must be rotated approximately 180 degrees according to whether it wants to tighten or release the corresponding nut.
The present invention consists of a wrench in four different modalities:
a) spanner in which one end is open and the other end contains a ratchet;
b) spanner in which both ends are open;
c) spanner in which both ends are closed; and
d) wrench where one end is open and the other closed.
The wrenches in which one end is open and the other end contains a ratchet, uses a color-coded identification system and an indicator to identify the sense in which it will be used; green to tighten or red to loosen up.
The wrenches according to the invention have their own color within each structure. The wrenches contain identified measurements that represent the nut that the key can manipulate corresponding to:
a) SAE (Society of Automotive Engineers—Society of Automotive Engineers), which is given in fractions or units of inch; and
b) metric system which is given in millimeters (mm).
The purpose of this invention is for the key to identify each number of nut size and/or logo with one color that is different from the one found in the structure of the key.
In general, the color code is:
The above color codes allow one to easily identify the direction in which to rotate the tool.
In addition to the colors used to identify the direction in which to turn, the key is printed on the size of the nut it manipulates, as well as a space to define the name of the manufacturer and an indicator showing in what sense it must be used.
This impression is made in such a way that the name of the manufacturer, the size number of the key and the indicator match the direction of rotation of the key in its sheath.
In the keys without a ratchet, the color code can go directly on the key or in the case. The color can be the same in the number and in the logo or brand of manufacturer. In the keys without a ratchet the size of each key has its own color code for the number and logo or brand of maker.
The present descriptive memory is complemented with a set of illustrative drawings of the preferred example and never limitative of the invention.
The present invention relates to a system of color coding in a key with color coding (100) characterized in that in its central part, the key (100) has one color (130).
The purpose of the present invention is to expedite the use of a key and in particular, a key with coding of color (100) by means of the use of a code of colors.
A first embodiment of the invention is shown in
More particularly, in
Likewise, in order to solve the problems of identification of the direction in which a key must be turned or key, the inventor proposes that the key with coding (100) shown in
The keys have different sizes according to the nut that it is manipulating. The size of the key (and therefore the nut) is identified with a numeric code, SAE and metric (mm). Examples of these keys are shown in
In the same
All the elements mentioned above can be printed on both sides or sides of the key with color coding (100) and in particular, it is intended that both sides have: the size identifier number of nut that manipulates the key in color (170); indicator 30 of the direction of rotation (150); and space for the logo (160), such and as seen in
In a first modality of the invention, the handle of color (130) is printed directly on the key (100) by any suitable means of printing or painting. This modality is appreciable in
In a preferred modality of the invention, the inventor has chosen the color blue so that it is the handle of color (130) in case of identifying the keys with SAE system. However, the manufacturer can change the grip of color (130) for one that suits best.
On the other hand, only by way of example, white has been chosen to be the color of the colored grip (130) in case the keys with metric system international. However, the manufacturer can change the color of the colored handle (130) for one that suits best.
The cover that is installed on the key (100) is made of plastic, rubber, polyurethane or any other material available and it can be seen installed in
In one modality of the invention, the colored grip (130) has the same color as the identifier number of the size of nut that manipulates the key (170) and the logo (160). All this according to the color code set for this type of keys.
In another modality of the invention, the colored handle (130) has a different color (in this yellow example) at of the identifier number of the nut size that manipulates the key (170) and the logo (160). All this according to color code set for this type of keys.
The color code shown in
The basic colors of manufacture of the key can be chromed, anodized or painted; in this example the color basic manufacturing for the keys identified with the metric system is white and for the identified keys with the SAE system, this color is brown.
In
For the assignment of the colors to identify the upper and intermediate nut sizes to those shown in the previous tables, it starts again from the colors used to identify smaller sizes of nut. However, the manufacturer can change the color of the nut size identifier number that manipulates the color key (170) for the one that suits best.
In another embodiment of the invention, the fixed-mouth wrench (100) can have both ends open (110), both closed ends (105) or one open end (110) and another closed (105) or an open end (110) and another end with ratchet (120).
The present invention is intended to be implemented in the keys to speed up their use and quality of production.
