Abstract

It reduces deformation of the frame and load on the hinges when opening and closing the seal case, preventing a decrease in engagement and holding force. [Solution] The seal case has a mouth part consisting of an engaging recess 17 and an engaging protrusion 18 between frames 13 and 14 attached to the seal storage member, and incorporates a movable engaging member 20 that is biased by a spring 21 so that it can move back and forth. This allows for smooth opening and closing operations and provides high durability.

Description

[Technical Field]

[0001] This invention relates to a seal case for storing seals, and in particular to a seal case that has been improved in the structure of the nozzle part of the opening and closing mechanism to facilitate smooth opening and closing operations and improve engagement and holding force. [Background technology]

[0002] A variety of seal cases have been proposed for safely and portable storage of seals. These types of seal cases typically include a pair of seal storage members and a frame attached to the edges of the storage members, with the frames connected to each other via hinges so that they can be opened and closed freely.

[0003] For example, Patent Document 1 (Utility Model Registration No. 3187386) discloses a technology that has a nozzle structure consisting of an engaging convex portion and an engaging concave portion, and keeps the seal case closed by fitting the engaging convex portion located at the end of the frame body into the engaging concave portion provided on the opposing frame body.

[0004] This engagement structure is designed so that the protruding convex portion is elastically pushed into the engagement recess while interfering with it during the engagement operation, and then is fixed at the mating position.

[0005] As described above, various mechanical engagement mechanisms have been proposed in the past to realize opening, closing, and engagement of the frame body in a seal case. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3187386 Summary of the Invention [Problem to be solved by the invention]

[0007] The engagement structure of conventional seal cases has an engagement protrusion fixed to the frame body and not movable, so when the seal case is closed, the frame bodies are temporarily deformed and forcibly engaged.

[0008] This can cause repeated loads to be applied to the hinge, which can lead to deformation and wear, and can also cause the engagement and holding force to decrease over long-term use, resulting in problems such as unintentional release. The purpose of this invention is to provide a seal case that reduces the load when opening and closing, smooths the engagement operation, and achieves stable engagement retention over a long period of time by introducing a movable engagement structure. [Means for solving the problem]

[0009] In order to solve the above problems, the seal case of the present invention has the following configuration.

[0010] That is, the seal case of the present invention is for storing seals and comprises a pair of seal storage members and a pair of frames attached to the peripheral edges of the storage members.

[0011] The frames are connected to each other by hinges so that they can be opened and closed, and furthermore, a mouth portion is provided that allows the frames to be engaged with each other.

[0012] This base portion is composed of an engaging recess attached to one side of the frame and an engaging protrusion attached to the other side.

[0013] The engaging protrusion has a storage section that stores the movable engaging member and the spring therein, and the spring is built into this storage section, and the movable engaging member is biased by the spring so that it can move forward and backward.

[0014] A portion of the movable engaging member is exposed to the outside from the housing portion and is capable of engaging with the engaging recess.

[0015] Furthermore, the movable engaging member may be configured as a spherical body, and the engaging recess may be formed with an engaging receiving portion that receives the spherical body in an engageable manner.

[0016] The spring may be a coil spring, which is disposed in a compressed state between the inner wall of the storage portion and the movable engagement member.

[0017] Furthermore, the storage portion can be configured as a metallic cylindrical member that is integrally formed with the engaging protrusion.

[0018] In addition, the engaging recesses and engaging protrusions are disposed in the center of the opening and closing ends of the frame so that force is transmitted equally between the left and right sides when opening and closing. [Effects of the Invention]

[0019] According to this invention, by incorporating a movable engaging member and a spring into the engaging protrusion, engagement and disengagement operations can be carried out smoothly when the frame bodies of the seal case are opened and closed.

[0020] In particular, the movable engaging member is biased by a spring so that it can move back and forth, allowing it to elastically engage with the engaging recess when engaging and to smoothly retreat when disengaging, so that engagement and disengagement can be performed with a natural movement without having to push the frame body apart or apply excessive force as in the past.

[0021] This reduces the risk of stress concentrating on the hinges due to temporary misalignment of the frames each time the case is opened or closed, preventing deformation and wear of the hinges, and thus improving the durability of the seal case's opening and closing mechanism.

[0022] Furthermore, when a spherical body is used as the movable engaging member, a uniform engaging pressure can be maintained in multiple directions, and a stable engaged state can be maintained by contact with the engaging receiving portion formed in the engaging recess.

[0023] Furthermore, by employing a coil spring as the spring and making the storage section a cylindrical member made of metal, it is possible to improve the holding stability and wear resistance of the member.

[0024] In addition, by locating the engaging recess and engaging protrusion in the center of the frame, the force exerted when opening and closing is distributed evenly to the left and right, further improving operability and structural stability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, one embodiment of the seal case according to the present invention will be described with reference to the drawings.

[0027] The seal case 10 of the present invention comprises a pair of seal storage members (not shown) with frame bodies 13 and 14 attached to the corresponding edges thereof, as shown in Figure 1. The frame bodies 13 and 14 are connected to each other via a hinge 15 so that they can be opened and closed.

[0028] The seal storage member (not shown) applicable to the present invention is a container for holding a seal, and may be made of synthetic resin, metal, or a composite material made by laminating or bonding these.

[0029] Furthermore, the inner surface of the storage member (not shown) may be provided with a cushioning material or a holding groove (not shown) for holding the seal.

[0030] The frames 13 and 14 may be molded integrally with the storage member (not shown), or may be attached as separate members with screws, adhesive, rivets, or the like.

[0031] The hinge 15 is not limited to a mechanical pin hinge, but may be a flexible resin hinge (film hinge), a leaf spring, a flexible joint, or the like.

[0032] The hinges 15 may be provided at the ends of the frames 13 and 14, or may be configured as long hinges that continue along the side or back surfaces.

[0033] As shown in FIGS. 2(a) and 2(b), an engaging recess 17 is formed in the frame 13, and an engaging protrusion 18 is provided on the frame 14 opposite thereto.

[0034] The engaging recess 17 is formed with a concave engaging receiving portion 22 that receives engagement with the engaging protrusion 18. The engaging protrusion 18 is provided with a movable engaging member 20 that engages with the engaging receiving portion 22. The engaging receiving portion 22 may be formed in any shape, such as a spherical shape, a conical shape, a V-shaped cross section, or a curved recess, depending on the shape of the tip of the movable engaging member 20.

[0035] As shown in FIG. 3, the engaging protrusion 18 is a protrusion provided on the edge of the frame 14, and a storage portion 19 is formed inside the engaging protrusion 18.

[0036] The storage section 19 is a cylindrical internal space, and is not limited to a cylindrical shape, but may be configured as a square tube, an elliptical tube, or a special shape having a guide groove on the inner surface.

[0037] Furthermore, the material of the storage section 19 is not limited to metal (for example, stainless steel or brass), but may be reinforced resin, ceramic, or composite material, and the most suitable material can be selected according to requirements for lightness and manufacturability.

[0038] As shown in FIG. 3, the movable engagement member 20 is housed in the housing portion 19 and is constantly biased forward by a spring 21 also housed in the housing portion.

[0039] The movable engaging member 20 is not limited to a spherical body, and may have a modified shape such as a hemisphere, a cylinder, a cone, an ellipsoid, a pyramid, etc. Depending on the shape, the tip may be tapered to improve the guiding ability of the engaging recess 17 into the engaging receiving portion 22.

[0040] The material of the movable engaging member 20 may be metal (stainless steel, iron, aluminum), resin (POM, nylon, etc.), ceramic, elastic material, etc., and is appropriately selected depending on the frequency of use and holding power.

[0041] A coil spring is most suitable for the spring 21, but a leaf spring, torsion spring, wave spring, or elastic member made of elastomer can also be used. The spring constant, number of turns, and free length of the spring are adjusted according to the engagement force and operating force.

[0042] FIG. 4 shows a state in which the movable engaging member 20 is retracted into the storage portion 19 when the engaging recess 17 and the engaging protrusion 18 are engaged with each other.

[0043] When the seal case 10 according to the present invention is in a closed state, as shown in FIG. 5, the movable engaging member 20 is pushed into the engaging receiving portion 22 of the engaging recess 17 and is securely engaged.

[0044] Furthermore, when the engagement recess 17 and the engagement protrusion 18 are disengaged from each other, the movable engagement member 20 temporarily retreats without any difficulty, and the engagement is smoothly disengaged.

[0045] Since the present invention is configured as described above, by incorporating a movable engaging member and a spring into the engaging protrusion, the engagement and disengagement operations can be carried out smoothly when the frame bodies of the seal case are opened and closed.

[0046] In particular, the movable engaging member is biased by a spring so that it can move back and forth, allowing it to elastically engage with the engaging recess when engaged and to smoothly retreat when disengaged, so that engagement and disengagement can be performed with a natural movement without having to push the frame body apart or apply excessive force as in the past.

[0047] This reduces the risk of stress concentrating on the hinges due to temporary misalignment of the frames each time the case is opened or closed, preventing deformation and wear of the hinges, and thus improving the durability of the seal case's opening and closing mechanism.

[0048] Furthermore, when a spherical body is used as the movable engaging member, a uniform engaging pressure can be maintained in multiple directions, and a stable engaged state can be maintained by contact with the engaging receiving portion formed in the engaging recess.

[0049] Furthermore, by employing a coil spring as the spring and making the storage section a cylindrical member made of metal, it is possible to improve the holding stability and wear resistance of the member.

[0050] In addition, by locating the engaging recess and engaging protrusion in the center of the frame, the force exerted when opening and closing is distributed evenly to the left and right, further improving operability and structural stability.

[0051] The engaging recesses 17 and the engaging protrusions 18 are preferably disposed in the center of the frames 13 and 14, but may also be disposed at the ends or corners of the frames, or at multiple locations, thereby achieving a balance between structural strength and aesthetic appearance.

[0052] In this way, the present invention allows for multiple alternative embodiments for each component, and various embodiments can be realized depending on manufacturing conditions, usage environments, and user needs. [Industrial Applicability]

[0053] The seal case of this invention is a container for safely carrying and storing seals, and can be widely used as a seal management tool for daily use not only in ordinary households but also in corporations, financial institutions, public institutions, educational institutions, medical institutions, etc.

[0054] In particular, this configuration, which has an improved engagement mechanism, exhibits high engagement retention and durability despite repeated opening and closing operations, making it highly practical as a product aimed at preventing seal loss and improving security.

[0055] In addition, the seal case of this invention has a simple structure, which reduces manufacturing costs and is suitable for mass production, so it can be widely used in the stationery industry, novelty goods, gift items, etc. [Explanation of symbols]
