SHOCK INDICATOR

Technical Field

[1] The present invention relates to a shock indicator, and, more particularly, to a shock indicator that can senses an impact applied from all direction including directions of up and down, front and rear and left and right, and indicate a strength of the impact if a strength of the impact is over an predetermined value. Background Art

[2] Typically, goods, which are delivered to users though a distribution channel, are attached with a shock indicator to prevent damages to the goods during a distribution, and to determine who is responsible for the damages to the goods. With an attachment of this shock indicator to goods, distributors can be more careful in handling the goods and thus users can receive the goods without damages.

[3] FIG.1 is a sectional view showing a shock indicator according to the prior art.

Referring to FIG.l, the prior shock indicator 1 includes a first tube 10, and a second tube 20 provided within the first tube 10. The first and second tubes 10, 20 are glass tubes one end of which is closed, respectively. Here, the inside wall surface of the first tube 10 is coated with white powder (not shown) served as a diffuser, and the interior of the second tube 20 is filled with a liquid dyes 30 of a predetermined color. At this time, an air layer of a predetermined thickness is provided between the opened- leading end of the second tube 20 and the surface of the liquid dyes 30 filled inside thereof. On this state, the second tube 20 is inserted to the inside of the first tube 10 and then sealed with an epoxy resin 50.

[4] The prior shock indicator 1, as configured in an aforementioned way, the air layer

40 is provided on the opened-end of the second tube 20, and thus the liquid dyes 30 cannot be separated into the first tube 10 due to the air layer 40.

[5] Under this state, when a shock of a predetermined strength is applied thereto, as shown in FIG. 2(a), the surface of the liquid dyes becomes inclined. In a more detail, when the strength of the shock applied thereto is less than or equal to a presetting value or a duration time of the shock application is less than or equal to a presetting value, the liquid dyes 30 not separated into the first tube 10. However, when the strength of the shock applied thereto is greater than or equal to a presetting value or a duration time of the shock application is greater than or equal to a presetting value, a part of the liquid dyes 30 is separated into the first tube 10, as shown in FIG. 2(b), and further the shock is kept in being applied for the entire first tube 10 to be activated with a color of the liquid dyes, as shown in FIG. 2(c).

Technical Problem

[6] Here, the prior shock indicator 1 can promptly sense and response to the shock applied in a direction of 45 ° or 90°, as shown in FIG. 3; however, it does not response (or hardly response) to the shock applied in a direction of left or right ± 0°. For example, when a response to the shock applied in a direction of 45 ° or 90° is 100%, the response to the shock applied in a left or right direction is about 10% or so. In particular, the prior shock indicator does not response the shock applied in a direction of inserting the second tube 20 into the inside of the first tube 10. As a result, as to the prior shock indicator, it has to be used as a pair and further each second tube 20 of the respective shock indicator 1 has to be attached to goods in an opposed direction.

[7] Accordingly, the present invention has been proposed to solve the above problem, and the object of the present invention is to provide a shock indicator, which can sense senses an impact applied from all direction including directions of up and down, front and rear and left and right, and indicate a strength of the impact if a strength of the impact is over an predetermined value. Technical Solution

[8] To achieve the aforementioned object, the shock indicator according to the present invention, comprises a housing formed as a hollow body on the inside wall surface of which at least one of pins protrude in the directions of up and down, front and rear, and left and right; and an ink ball that hung movable on a center of the housing, which is spaced at a predetermined distance from the leading end of the respective pin; wherein when a shock is applied thereto, the ink ball collides with the pins to discharge the ink filled therewithin and thereby activating the housing as an ink color.

Advantageous Effects

[9] In the shock indicator according to the present invention, the housing on the inside of which a plural pins are provided and the ink ball that is provided movable in the interior of the housing, are used to response the shock applied from all directions including the directions of up and down, front and rear, and left and right. In addition, when the strength of the shock is over a predetermined value, it is indicated to the outside of the housing.

[10] Additionally, even when the ink discharged to outside is removed, it can be determined whether the shock is applied by confirming the state of the ink ball. Brief Description of the Drawings

[19] Hereinafter, referring to the attached drawings, the embodiments according to the present invention will be described in detail. Here, when the descriptions of the known constitutional elements among which constitute the present invention, and the effects thereof make the gist of the present invention unclear, the detailed description thereof are omitted. Additionally, is has to be understood that same reference numerals are given to the same elements even they are shown in different drawings.

[20] FIG.4 is a partly sectional perspective view showing the shock indicator according to the present invention and FIG. 5 is a front sectional view and side sectional view of FIG.4. Referring to FIGs. 4 and 5, the constitution of the shock indicator according to the present invention is as followings. Here, as to the shock indicator of the present invention will be described based on the direction shown in FIG. 5.

[21] The shock indicator 100 according to the present invention includes a housing 110 and an ink ball 120 provided inside the housing 110.

[22] The housing 110 is formed as a hollow body for housing the ink ball 120, and an opening 112 is formed on one side thereof with which a label 200, which will be described later, is contact. Here, a diaphragm 114 with a predetermined elasticity is connected to the opening 112 to seal the inside of the housing 110. In addition, at least one of pins 116 protrudes on the inside wall of the housing 110 in directions of up and down, front and rear, and left and right, and a plural of minute exit holes 118, which communicate with the inside of the housing, are formed on the surface thereof.

[23] At this time, the pins 116 provide on the inside wall surface of protrude toward a center of the housing 110 from the directions of up and down, front and rear, and left and right. Here, pins that are provided in an opposed direction form a pair. In addition, the housing 110 is formed as a sphere such that a spaced distance between the inside wall surface thereof and the ink ball 120 is identical through a circle. Preferably, the

distance between the respective leading end of the plural pins 116 that protrude from the inside wall surface of the housing 110 and the ink ball 120 is spaced to be identical. Meanwhile, the pin may not be formed on the side of the diaphragm 114, which will be described later. In addition, it has to be understood that even though the pins are provided on up and down, front and rear, and left and right of the inside wall surface of the housing 110, as shown in drawings and described in the specification of the present invention; however, the present invention is not limited to this configuration and thus the numbers and locations may be modified based on the user's necessity.

[24] When the distance between the leading end of plural pins 116 and the ink ball 120 is spaced to be identical, the shock indicator can response identically to the shocks of same strength in directions of up and down, front and rear, and left and right. For example, when the distance between the pins 116e, 116f that protrude in left and right directions and the ink ball 120 is larger than those between the pins that protrude in directions of up and down, and front and rear, and the ink ball 120, the shock indicator may not response to the shock applied in left and right directions even the shock of same strength is applied in respective direction. Accordingly, it is preferable that all distance between the leading ends of plural pins 116 and the ink ball 120 are spaced to be identical.

[25] In addition, the ink ball 120 is formed as a spherical shape and ink 122 of predetermined colors is filled therein, and can be movable in the middle of the housing 110 with being hung on a string 124. At this time, the ink ball 120 is preferably made of soft resin to discharge the ink 122 filled therein when the ink ball 120 collide with the pins 116. In addition, the string 124 is preferably elastic to be extended when shock is applied thereto.

[26] The reason for the string 124 a predetermined elasticity to be used is that the ink ball 120 becomes movable when a shock is applied thereto in direction of up and down. For example, when a general string without elasticity is used, it cannot be extended when the shock is applied in a down direction, and thus the ink ball 120 together with the housing do not move in a up direction to collide with the pins. Accordingly, since when a large shock is applied, the shock indicator 100 cannot be activated (an phenomenon of the ink in the inside of the ink ball not being discharged) and thus the string 124 has to be extendable as an elastic string.

[27] The shock indicator 100 as configured in a aforementioned way is connected through a label 200 with which an attaching surface 210 is provided on one side thereo f, and the label 200 together with the shock indicator are attached to goods.

[28] The steps of activating the shock indicator as attached to the goods in aforementioned way will be described referring to FIGs. 6 to 8.

[29] FIG. 6 is a view showing the steps of activating the shock indicator according to the

present invention, when the shock is applied thereto in up and down direction. As shown in FIG. 6(a), when a shock (S) is applied from an upper part of the shock indicator, only the housing 110 is moved downwardly while the ink ball 120 being stationary, and thus the ink ball 120 is to collide with the pin 116A that is provided on the inside wall surface of the housing 110. That is, the ink ball 120 moves relatively to the housing 110 and thus collides with the pin 116a. At this time, when the strength of the shock (S) is equal to or greater than a predetermined value, the surface of the ink ball 120 is torn down with the upper pin 116a and thus the ink 122 filled there within is discharged to the inside of the housing 110. The ink 122 discharged to the inside of the housing 110 is exited to the outside of the housing 110 through the exit hole 118 formed on the surface of the housing 110, thereby activating the shock indicator 100.

[30] When a user confirms the shock indicator 100 being activated, he/she can see whether shock is applied to goods. Here, even when the ink 122 that is exited to the outside of the housing 110, is removed, he/she can see whether the ink ball 120 is broken and thus a trace of shock cannot be eventually removed.

[31] FIG. 6(b) is a view showing a case where the shock (S) is applied from the lower part of the shock indicator 100, wherein it is only different in the direction from FIG. 6(a), and the shock indicator is activated through similar steps and thus a detailed description thereof is omitted.

[32] FIG. 7 is a view showing the steps of activating the shock indicator, when the shock is applied thereto in front and rear direction. As shown in FIG. 7 (a), when the shock (S) is applied from the front of the shock indicator 100, only the housing 110 is moved rearward while the ink ball 120 being stationary, and thus the ink ball 120 collide with the pin 116c provided on the front of the inside wall surface of the housing 110. At this time, the surface of the ink ball 120 is torn down and the ink 122 filled there within is discharged to the inside of the housing 110. The discharged ink 122 is exited to the outside of the housing 110 through the exit hole 118 formed on the surface of the housing 110, as described above, thereby activating the shock indicator 100.

[33] Meanwhile, as shown FIG. 7(b), when the shock (S) is applied from the rear of the shock indicator 100, only the housing 110 is moved frontward while the ink ball 120 being stationary. That is, the ink ball 120 is moved relative to the housing 110 and contacted with the diaphragm 114. At this time, the ink ball 120 is bounded upon the elasticity of the diaphragm to collide with the pin 116c provided on the front of the inside wall surface of the housing 110. As a result, the surface of the ink ball 120 is torn down and the ink 122 filled therewithin is discharged to the inside of the housing 110 and thereby activating the shock indicator 100.

[34] As to the shock indicator 100 according to the present invention, as configured in an aforementioned way, any pins are not provide on the side of the diaphragm 114 to

activate the shock indicator 100.

[35] FIG. 8 is a view showing the steps of activating the shock indicator, when the shock is applied thereto in left and right direction. As shown in FIG. 8 (a), when the shock (S) is applied from the left of the shock indicator 100, only the housing 110 is moved right side while the ink ball 120 being stationary. At this time, the ink ball 120 is collided with the pin 116e provided on the left side of the inside wall surface of the housing 110. As a result, the surface of the ink ball 120 is torn down and the ink 122 filled there within is discharged to the inside of the housing 110 and thereby activating the shock indicator 100.

[36] As to the shock indicator 100 as shown in FIG. 8(b), the shock (S) is applied from the right thereof, and it is only different in the direction from FIG. 8(a), and the shock indicator is activated through similar steps and thus a detailed description thereof is omitted. Industrial Applicability

[37] Though the configuration of the shock indicator and the steps of activation thereof are described according to the preferred embodiments of the present invention, referring to the aforementioned description and drawings, it is only intend to show the exemplary shock indicator. Accordingly, it has to be understood that various changes and modifications thereof can be made by the person with an ordinary skill in the art without departing the spirit of the present invention.
