Description

Lock dial disk {dial lock disk}

The present invention relates to a lock dial disc included in a lock that can be opened by rotating a numbered cylindrical dial disc with a number, and the identification groove and identification projection on a curved surface (hereinafter referred to as a 'side curved surface') corresponding to the side of the dial disc. It is about a dial disc that allows the user to set the password by turning the dial disc with a tactile feel without looking at it.

In general, in the case of a rotary dial lock that rotates a dial disc engraved with a number to lock or unlock a combination of numbers, it consists of a housing and one or more dial discs, and the dial disc is cylindrical and corresponds to the side of the cylinder. Each of the numbers 0 to 9 is engraved on the side curved surface, and notches are formed therein, so that the fastening end is configured to be separated from or coupled to the housing only when a predetermined number comes to a certain position.

In this case, although there are grooves of a certain interval on the side curved surface of the dial disc and a number is written between each groove, there is no division according to each number in the groove portion, so a dark place or time where visual information is blocked Users with disabilities had difficulty using them.

In addition, there was a security risk that the password on the dial could be easily seen by other people, and the password was easily exposed.

Utility Model Registration No. 20-0464724

In order to solve the problems as described above, the present invention provides a means for distinguishing each number only by tactile sense, and forms an identification groove or / and an identification protrusion only on one or two numbers symmetrical to each other on the dial disk. By providing a means to perform the function of identification through tactile by simply adding a simple process, it provides a means to prevent the password from being visually exposed, and can be used as it is by replacing it in a housing where a conventional dial disc is used. Provides a means.

Furthermore, the present invention provides a means for visually impaired people to conveniently use the size of the grooves or protrusions to fit a standard braille standard size of 1.5 mm in radius and a protrusion height of 0.6 to 0.7 mm specified by the Korean Federation of Visually Impaired. to provide.

Typically, the lock is composed of a housing and a cylindrical disk-shaped dial (this is referred to as a 'dial disk' in the specification), and a number or letter is engraved on the side curved surface 4 of the dial disk, and inside the dial disk The notch of a certain rule is formed, and the housing includes a protruding flange that can be combined with them. When the dial disc is rotated, the notch formed inside the disc is combined with the protruding flange on the body, so that the password fits. to be.

The present invention is the design of the dial disk portion of the parts of the lock, and the notches, etc., which are combined with the flanges of the body are the same as the normal lock, and are not specifically mentioned or expressed in this specification, and the dial disk, which is the feature of the present design, The identification groove 1 formed on the side curved surface 4, the curved identification groove 1 '(hereinafter referred to as' the curved identification groove is collectively referred to as the identification groove)' and the identification projection 2 will be described only.

1 is a perspective view showing an embodiment of the present invention. An identification groove (1) was created on the side curved surface (4) corresponding to a number ('6' in the figure) expressed on the dial disc so that '6' can be recognized when touched by hand. In addition, the side curved surface corresponding to the number '1' which is symmetrical to '6' is provided with an additional identification groove 2 and an identification protrusion 2 inside the groove, so that the user can recognize that it is '1' , It was also to be distinguished from the '6'.

Due to this configuration, the user can grasp the position of the '1' on the dial disc with only the touch of a hand, from which '2' when moving one space forward, '3' when moving two spaces, and three spaces when moving the two spaces '4', '4' if you move four spaces, and if you move one more space, you can confirm that it is '6' distinguished by the identification groove (1), and the number of '7' to '0' is also like this. Can be found with

In particular, since the identification groove (1) and / or the identification protrusion (2) are created in the '1' and '6', the user can fit all numbers within 2 spaces. For example, '1' and '6' can be found directly by the identification groove (1) and / or the identification protrusion (2), '5' moves one space back from '6', and '4' is It moves two spaces backward from '6', and '3' moves two spaces forward from '1'.

Since all numbers can be found in two counts, the password can be easily set with a relatively simple operation, omitting the process of printing all numbers on the side surface (4) of the dial disk, and only the side surface corresponding to the two numbers Since the identification mark can be used, the manufacturing process also has a simple advantage.

In FIG. 1, the identification groove 1 and the identification protrusion 2 are expressed in a simple shape, but the shape of each corresponding number may be expressed in an uneven shape such as intaglio or embossed, or may be expressed in the shape of a logo or character of a specific brand. have.

2 is a perspective view showing another embodiment of the present invention. The identification groove is made to be curved, so that the busbar of the side curved surface 4 corresponding to a number ('1' in Fig. 1) expressed in the dial disk is formed in a curved shape curved in the axial direction of the dial disk to identify the curved curve. I made a groove (1 '). 3 is a view showing the front surface of the dial disk, and it can be seen that the side curved surface of the place corresponding to a number is curved toward the axis to form a curve. At this time, the circumference (3) of the dial disc has the same shape as the rest of the numbers, so as shown in FIG. 4, when the dial disc is viewed from above, the numbers are not distinguished.

Therefore, the user can easily find the corresponding number with the touch of a hand, but it is not easy to distinguish the number from the other number by sight even if the other person is watching from the side, so the risk of exposing the password is reduced.

The curved discrimination groove 1 'has a circumference of the dial disc that is the same as that of a normal dial disc compared to a general discrimination groove, so that it is easy to change the production process, and can be easily mounted on a padlock to which a basic dial disc is applied. In addition, as compared to the general identification groove 1, the edges have sharp edges, and the curved surface has a large difference in tactile sensation, such as being curved, so it is not only easier to distinguish by tactile sense, but also the curved surface is the fingertip of the user. It can provide a better feel to the user in a shape that corresponds to. Furthermore, since there is no difference between the displayed number and other numbers on the circumferential surface, it is difficult to visually distinguish the displayed number, which is more excellent in security than the dial disc displaying the general identification groove 1.

In the embodiment as shown in FIG. 2, the curved disc identification groove 1 'is also added to the number (' 6 'in FIG. 2) that is symmetrical to the corresponding number, and the added bending identification groove 1 An identification protrusion 2 is placed in ') to distinguish it from other numbers and numbers marked with curved identification grooves 1' (number '1' in FIG. 2).

The identification groove (including the curved identification groove) (1,1 ') and the depth (5) / height of the identification protrusion included in the dial disc according to the present invention is a radius of 1.5, which is the size of the standard braille standard specified by the Korea Federation of the Blind. It is desirable to make it 0.5 to 1 mm to fit the standard of the existing lock dial disc while being suitable for classification by tactile sense in accordance with mm and protrusion height of 0.6 to 0.7 mm.

The present invention can be applied to a padlock in a form attached to a bag, furniture, etc., a padlock with several dial discs stacked, as well as a simple padlock made of one dial disc, as shown in FIG. 5.

The dial disc lock according to the present invention can match a password only with a touch, so a visually impaired person can easily use it, thereby reducing discrimination in design for the disabled person.

In addition, since the password is not exposed visually, the risk of leaking the password is reduced even if the password is matched to keep the lock or use it in a public place with many people.

Furthermore, it is easy to use the password in a dark place because the password can be set with only tactile sense, and it can be used in a belonging box such as a lodging facility used by many people so that the lock can be operated at night without turning on the light.

In addition, the dial disk according to the present invention can omit the process of printing a number on the side curved surface of the disk, thereby saving production cost, and there is no problem of discarding the lock because the number is erased due to long use. It can be applied directly to the locks of the machine, which can also contribute to material saving.
