Description

[Technical Field]

[0001] This device relates to a display stand for jewelry, and more specifically to a case for displaying jewelry that has been cut and polished from a rough stone (hereinafter referred to as loose stones). [Background technology]

[0002] Loose stones that are not attached to a base or frame are sometimes displayed in a loose stone case for the purpose of checking the condition of the loose stone and appreciating it. Conventional loose stone cases have a transparent lid and a support that hold and secure the loose stone, and are used for display purposes.

[0003] Simply holding the loose stones between the lid and the support makes the loose stones more likely to move around inside the case, which not only makes it less aesthetically pleasing but also risks damaging the loose stones. Therefore, a loose stone case has been proposed that uses a cushioning material for the support, with the aim of preventing the loose stones from moving around inside the case (Patent Document 1).

[0004] However, when a cushioned material is used for the support, the lower half of the loose stone becomes buried in the cushion, and in particular, loose stones with culets are mostly buried in the cushion, making it impossible to appreciate the entire stone.

[0005] Therefore, a loose stone case has been proposed for loose stones with culets, in which a small hole is provided in the support to accommodate the very tip of the culet (Patent Document 2). When the culet is accommodated in the small hole in the support, there is an advantage in that the brilliance of the loose stone is amplified by the light reflected from the support.

[0006] [Patent Document 1] Utility Model Registration No. 3025663 [Patent Document 2] Utility Model Registration No. 3054307 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in order for the curette to be stably clamped between the lid and the loose stone housed in the small hole of the support, there was a problem in that it was necessary to either adjust the height of the lid appropriately or to prepare a lid that matched the height of the loose stone.

[0008] Therefore, an object of the present invention is to provide a loose stone case that can reliably hold a loose stone having a culet regardless of the angle of the culet or the height of the loose stone when storing the loose stone. [Means for solving the problem]

[0009] In other words, the loose stone case of the present invention is intended to achieve the above-mentioned object, and is a loose stone case for displaying loose stones having culets, comprising a lid that abuts the top of the loose stone, and a support having a recess for storing the culet, the support comprising a seat portion including the recess, and a base portion that is formed by extending outward from all four sides of the seat portion and then bending downward, the support being made of an elastic material, the thickness of the seat portion decreasing from the boundary with the base portion to the center, and the center portion having a lower protrusion formed in accordance with the shape of the recess.

[0010] The loose stone case of the present invention is characterized in that the lid and the support are fitted together to sandwich the loose stone.

[0011] In addition, the loose case of the present invention is characterized in that the cover comprises a window portion made of a transparent plate and a frame portion joined to all four sides of the window portion and surrounding the window portion.

[0012] The loose case of the present invention is characterized in that the frame portion is formed with an engaging recess, and the base portion is formed with an engaging protrusion. [Effects of the Invention]

[0013] When a loose stone is stored in the loose stone case of the present invention, it can capture light not only from above but also from a portion of the bottom, allowing the stone to shine brightly. Furthermore, the loose stone is held in place by an elastic mechanism, ensuring the necessary stability within the loose stone case. Furthermore, the seating surface is elastically deformable, allowing it to accommodate loose stones of various sizes. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. [Example]

[0016] Fig. 1 is a perspective view of the state in which the lid body 10 of the loose case 1 of the present invention is placed on the support body 20. Fig. 2 is a perspective view of the support body 20 of the loose case 1 of the present invention. Fig. 3 is a perspective view of the lid body 10 of the loose case 1 of the present invention. Fig. 4 is a cross-sectional view taken along line AA of the state in which the lid body 10 of the loose case 1 of the present invention is placed on the support body 20. Figs. 1 to 4 show the state in which loose coins 30 are stored.

[0017] The loose stone case 1 of the present invention is suitable for displaying loose stones 30 of the shapes exemplified in Figures 1 to 4, i.e., loose stones 30 having a culet 31 formed thereon and a flat top. The culet 31 is stored in a recess 22 formed in the center 21 of the support 20, and the loose stone 30 is sandwiched between the window 11 of the lid 10 that abuts against the top of the loose stone 30 and the center 21 of the support 20, allowing the loose stone 30 to be stably displayed.

[0018] Fig. 5 is a front view of the lid 10 of the loose case 1 of the present invention. Fig. 6 is a plan view of the lid 10 of the loose case 1 of the present invention. Fig. 7 is a bottom view of the lid 10 of the loose case 1 of the present invention. Fig. 8 is a cross-sectional view of the lid 10 of the loose case 1 of the present invention taken along line BB.

[0019] The lid 10 of the loose stone case 1 of the present invention comprises a window 11 made of a transparent plate and a frame 12 that joins to all four sides of the window 11 and surrounds it. The frame 12 has a predetermined height, and the window 11 and frame 12 form an open bottom surface of the lid 10. The window 11 of the present invention is preferably made of a highly transparent material to allow light in. Furthermore, since the window 11 comes into contact with the loose stone 30, it is preferable that the window 11 be coated to make it scratch-resistant.

[0020] Engagement recesses 13 are formed on the four inner surfaces of the frame 12. The engagement recesses 13 engage with the support 20 when the lid 10 is fitted to the support 20. Details will be described later.

[0021] Fig. 9 is a perspective view of the support 20 of the loose case 1 of the present invention. Fig. 10 is a front view of the support 20 of the loose case 1 of the present invention. Fig. 11 is a plan view of the support 20 of the loose case 1 of the present invention. Fig. 12 is a cross-sectional view of the support 20 of the loose case 1 of the present invention taken along line CC. All of Figs. 9 to 12 show a state in which no loose coins 30 are placed on them.

[0022] The support 20 of the loose case 1 of the present invention comprises a seat 23 including a recess 22 for accommodating a curette 31, and a base 24 formed by extending outward from all four sides of the seat 23 and then bending downward. The support 20 is made of an elastic material, and the thickness of the seat 23 decreases from the boundary 25 with the base 24 to the central portion 21, and the central portion 21 is formed with a lower protrusion 26 according to the shape of the recess 22. The material of the support 20 is preferably elastic, flexible, and capable of retaining its shape. Specifically, silicone rubber is suitable, but is not limited to this. The support 20 of the loose case 1 of this embodiment has the seat 23 and base 24 integrally formed.

[0023] The shape of the recess 22 that houses the culet 31 is preferably tapered to match the shape of the culet 31, but it is sufficient if the slope of the taper of the recess 22 is narrower than the angle of the culet 31, and the shape of the recess 22 may also be a cylindrical hole.

[0024] As shown in Fig. 12, the upper surface of the seating surface 23 of the support 20 is horizontal when no loose stone 30 is placed on it. When the culet 31 is stored in the recess 22 and the lid 10 is placed on the support 20, the center 21 of the support 20 is pressed down together with the loose stone 30 pressed down by the window 11, and the loose stone 30 is stabilized by the elasticity of the seating surface 23 and the sandwiching between the window 11, as shown in Fig. 4.

[0025] Engagement protrusions 27 are formed on the four outer surfaces of the base portion 24. As shown in Fig. 4, the engagement protrusions 27 engage with the engagement recesses 13 of the support body 20 when the lid body 10 is fitted to the support body 20. Because the support body 20 is made of an elastic material, the fit between the lid body 10 and the support body 20 is sufficiently stable.

[0026] The support body 20 of the loose case 1 of the present invention has a base portion 28 formed on the lower outer sides of the base portion 24 on all four sides, and a groove portion 29 formed in one location in the center of the outer upper end of the base portion 28. Furthermore, the lid body 10 and the support body 20 are formed so that the lower surface of the frame portion 12 abuts against the upper surface of the base portion 28 when they are fitted together. When removing the lid body 10 from the support body 20, it is easy to lift the lid body 10 by inserting a finger into the groove portion 29. [Explanation of symbols]
