Here, the inner cover 131 and the inner support plate 133 might be integrally formed by the casting method and might be provided in various shape such as a triangle shape, a square shape, a hexagonal shape, etc. in addition to a rectangular shape as long as it maintains a support function,
At least one rotation shaft engaging hole 135 is formed at the inner sides of the upper and lower inner covers 131 and 132 of the female cover 130 and the rotation shaft engaging hole 135 is an engaging hole through which passes the rotation shaft member 115, so it is engaged.
The female cove 130 of the pencil case 100 according to a first embodiment of the present invention comprises the rotation shaft engaging holes 135, two of which are formed at the upper inner cover 131 and the lower inner cover 132, respectively.
The female cover 130 is smaller than the male cover 110 (at least one among the height, width and length), and the female cover 130 can be slide-inserted into the passed-through interior of the male cover 110.
At this time, the rotation shaft member 115 protruded from the inner side of the male cover 110 is inserted into and engaged to the rotation shaft engaging hole 135 formed at the inner covers 131 and 132 of the female cover 130.
In other words, the male cover 110 is engaged by way of the rotation shaft engaging hole 135 of the female cover 130 and the rotation shaft member 115, so the male cover 110 and the female cover 130 are engaged and can be rotated in the clockwise direction and the counterclockwise direction.
As shown in FIGS. 5 to 7, one male cover 110 and two female covers 130 can be engaged in such a way that they can rotate by way of the rotation shaft member 115 and the rotation shaft engaging hole 135.
For more specific descriptions, the following reference numerals will be given to the rotation shaft member 115 and the rotation shaft engaging hole 135.
The male cover 110 comprises a first rotation shaft member 115 a, a second rotation shaft member 115 b, a third rotation shaft member 115 c and a fourth rotation shaft member 115 d.
The female cover 130 has features in that the inner cover 131 comprises a first rotation shaft engaging hole 135 a, a second rotation shaft engaging hole 135 b, a third rotation shaft engaging hole 135 c and a fourth rotation shaft engaging hole 135 d. The female cover 130 positioned at the right lower side with respect to the male cover 110 is referred to the first female cover 130 a, and the female cover 30 positioned at the left upper side is referred to the second female cover 130 b.
The protrusions protruded from the right portion with respect to the plane of the male cove 110, namely, the first rotation shaft member 115 a and the third rotation shaft member 115 c are engaged to the engaging holes formed at the left portion of the first female cover 130 a, namely, the second rotation shaft engaging hole 135 b and the fourth rotation shaft engaging hole 135 d, so the male cover 110 and the first female cover 130 a are engaged and can be rotate in the clockwise direction and the counterclockwise direction.
The protrusion protruded from the left shaft portion of the male cover 110, namely, the second rotation shaft member 115 b and the fourth rotation shaft member 115 d are engaged to the engaging holes formed at the right portion of the second female cover 130 b, namely, the first rotation shaft engaging hole 135 a and the third rotation shaft engaging hole 135 c, so the male cover 110 and the second female cover 130 b are engaged and can be rotated in the clockwise direction and the counterclockwise direction.
The user of the pencil case 100 can engage so that it can rotate along with the another male cover 110 by sliding it the first female cover 130 a in the rightward direction and can sequentially engage so that it can rotate along with another male cover 110 by sliding the second female cover 130 b in the leftward direction, so the length of the pencil case 100 can be prolonged.
In addition, the male cover 110 to the female cover 130 are partially engaged or disengaged from the pencil case 100 to which are sequentially engaged a plurality of the male covers 110 and a plurality of the female covers 130, so the length of the pencil case 100 can be reduced if it is necessary.
In addition, it is obvious that the whole shape, size and length of the pencil case 100 can be adjusted by adjusting the widths, depths, lengths and shapes of the male cover 110 or the female covers 130.
