Description

[Technical field]

[0001] The present invention relates to a protective cover with a strap for a mobile device that is arranged along the side in its natural state and can be gripped by pinching the back of the hand when held, thereby assisting in gripping. [Background technology]

[0002] Mobile phone straps are accessories that are attached to mobile phones, smartphones, tablets, etc. to make them easier to carry or for decorative purposes. Generally, straps have a small string or chain attached to them and can be attached directly to mobile phones. Straps often have decorations of various designs and characters, making them popular as items to express one's individuality. The history of mobile phone straps began with the spread of mobile phones, and they are known to be particularly popular in Japan. Currently, many straps and holders for smartphones are sold, and many products are seen that combine both functionality and fashion.

[0003] For mobile phone straps that are not particularly intrusive when not in use, choosing a slim, thin and lightweight strap will not take up much space in your pocket or bag and will be easy to use, and a wrist strap that you can wear around your wrist is convenient when taking out your phone and reduces the risk of dropping it. In addition, soft and simple materials such as silicone and nylon are less likely to get caught on things than hard materials, making them easier to carry, and clip-type or magnetic straps that are easy to attach and remove are convenient because they can be easily removed and attached.

[0004] For example, the following Patent Document 1 discloses an invention for an expandable strap for a mobile phone, which aims to provide an expandable strap for a mobile phone made of a cheap coated rubber cord that is easy to process and easy to use for any type of strap. The expandable strap 1 comprises an expandable rubber cord 2 that is folded in half, with the inside of the cord 2 being the span 3, and the size of the loop being a size that fits the wrist comfortably. The expandable rubber cord 2 is folded in half to form an expandable rubber cord 2 with the inside of the cord 2 being the span 3, and the end of the expandable rubber cord 2 is folded in half to form an expandable rubber cord 2 that is large enough to fit the wrist comfortably. A connecting cord 5 made of a thin cord folded in half for connecting to a mobile phone is attached to the end of the expandable rubber cord 2 via a fastener 4 in the shape of a character such as an animal or doll.

[0005] In the mobile phone strap disclosed in this document, in order to eliminate the inconvenience and difficulty of use of conventional straps, first, a covered rubber cord made of a flexible, light rubber material that stretches more than twice its size is used as the string material used to make the strap stretch.The covered rubber cord is folded in half to form a ring shape, and large, medium and small covered rubber cord ends are attached to which is a thin connecting cord that is folded in half to connect to a mobile phone, and a straight type stretch strap is constructed in which one end of a fixed length of covered rubber cord has a clip attached to it and the other end has a connecting cord for connecting to a phone attached.

[0016] [Figure 1] FIG. 2 is a schematic diagram illustrating a protective cover with a strap for a mobile terminal according to the present invention; [Diagram 2] FIG. 13A is a diagram illustrating a protective cover with a strap according to a second embodiment, and FIGS. 13B and 13C are conceptual diagrams illustrating the configuration of a protective cover according to a third embodiment. [Diagram 3] 11A to 11C are diagrams illustrating a method of using the protective cover of the first embodiment when the protective cover is held in the left hand as a handle. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Some mobile phone straps have a function to assist with holding the device, and are designed to make it easier to hold the device firmly. For example, a ring strap has a ring on the strap that you can put your finger through, allowing you to hold the device firmly by putting your finger through the ring. There are also hand straps that are attached to the back of the device and are shaped to fit the palm of your hand, making it easier to hold by putting it through your wrist. Wrist straps that are worn around the wrist not only prevent the device from being dropped, but also make it easier to carry.

[0018] However, when the mobile terminal is not in use or not being held (grip), there is a demand for a strap that can be firmly fixed to the mobile terminal and assists in holding it when in use, so that it does not become bulky, get caught on other objects, swing unintentionally and come into contact with surrounding objects, or make unnecessary and unpleasant noises. There is also a need for a protective cover for the mobile terminal that can firmly and stably fix and maintain such a strap.

[0019] First Embodiment Fig. 1 is a conceptual diagram illustrating a protective cover 1000 with a strap for a mobile terminal according to the present invention. As shown in Fig. 1(a), the protective cover 1000 according to the present invention covers at least a part or all of the exposed outer surface and periphery of a mobile terminal 1600, and has a function of protecting the mobile terminal 1600 to a certain extent from scratches, damage, and dirt caused by impact or contact applied to the mobile terminal 1600.

[0020] 1(a), the upper end of the protective cover 1000 is provided with a fixed end 1100, which is a through hole for fixing a strap 1200. Generally, the protective cover 1000 is often made of a relatively soft material such as leather or PVC, so if a through hole is simply provided, the through hole will be relatively weak against tensile stress and has poor durability. For this reason, in the protective cover 1000 of the present invention, the fixed end 1100 has an eyelet structure, that is, the peripheral portion of the through hole (the inner circumference of the through hole) is covered and fixed with a ring made of metal or resin.

[0021] Here, the eyelet structure refers to a ring made of metal or plastic, etc., used to reinforce holes in materials such as cloth, leather, and plastic, and the eyelet is used to prevent the material from tearing or fraying when passing a hole or threading a string or cord through it. Well-known uses include reinforcing holes for shoelaces in shoes and boots, reinforcing straps and chains in bags and wallets, and used in clothing items that require fastenings such as corsets and jackets, and reinforcing canvases and tents to pass ropes or strings for fixing. The use of such eyelets can increase the durability of the material and produce a beautiful finish.

[0022] 1(a) and 1(b), a locking end 1400 reinforced with a reinforcing material is provided at the bottom end of the protective cover 1000 to detachably lock the strap 1200. The reinforcing material of the locking end 1400 preferably has a certain degree of hardness to prevent deformation even when stress is applied by maintaining the shape of the locking end 1400 against the protective cover 1000 made of a relatively soft material, and to prevent wear, abrasion, and damage even when multiple attachment and detachment operations are performed. The reinforcing material of the locking end 1400 may be shaped to cover the bottom end of the protective cover 1000 with, for example, a metal edge or plastic resin, or may be fitted into the bottom end of the protective cover 1000 like a dental cap.

[0023] A first end 1210 of the strap 1200 is fixedly secured to the fixed end 1100, and a second end 1220 of the strap 1200 has a hook 1300 which is releasably secured to a retaining end 1400 reinforced with a reinforcing material.

[0024] In addition, in a natural state where the hook 1300 is detachably engaged with the engaging end 1400, the strap 1200 is arranged along one side 1500 of the protective cover 1000, and is preferably made of a stretchable and flexible spring member, a spiral string, a rubber string, etc. In addition, the hook 1300 shown in Fig. 1(b) is not particularly limited as long as it has a structure, shape, and material that allows it to be detachably engaged with the engaging end 1400, and a known engaging member such as a hook of any shape or a clip / hook can be used.

[0025] 1(c), for example, the left hand can be passed between the protective cover 1000 and the strap 1200 as a handle 1700, so that the strap 1200 can support and guide the back of the handle 1700. This allows the mobile terminal 1600 to be stably held by the left hand alone, even when viewing the screen of the mobile terminal 1600 or operating it with the right hand. In this case, the first end 1210 of the strap 1200 is attached to the fixed end 1100 of the protective cover 1000, and the second end 1220 is attached to the locking end 1400 of the protective cover 1000 via the hook 1300, so that the strap 1200 forms a closed loop and can function sufficiently as a guide for the back of the hand.

[0026] When the hook 1300 is released from the locking end 1400, the hook 1300 and the second end 1220 of the strap 1200 are freed, so that the hook 1300 can be locked to, for example, trousers or a belt, a tool belt holder, or a handle, belt loop, pull tab, or any other desired location of a bag or pouch. This makes it possible to prevent the mobile terminal 1600 from being dropped or lost. The hook 1300 can also be hooked to a breast pocket or a belt loop of trousers to prevent the mobile terminal 1600 from being dropped. FIG. 3 is a diagram for explaining how to use the protective cover 1000 of the first embodiment when the left hand 1700 is held as a handle.

[0027] Second Embodiment Fig. 2(a) is a diagram illustrating a protective cover 1000 with a strap 1200 according to a second embodiment. In the strap 1200 shown in Fig. 2(a), a clip 1230 that can be freely engaged is provided at the second end 1220 instead of the hook 1300. Since the second embodiment is the same as the first embodiment except for the hook 1300 portion, the same reference numerals are used and the description thereof is omitted. The clip 1230 is engaged by clamping it against the engaging end 1400, and may be made of plastic, metal, or any other material.

[0028] The clip 1230 can be configured to be user-friendly, since even children and infants can easily handle and attach / detach it, and it is also easy to make it lightweight and small. Furthermore, the clip 1230 has a relatively simple structure compared to the hook 1300, which can significantly reduce concerns about malfunction and wear, and the structure exposed to the outside can be structured with few irregularities and no flat protrusions, which can further reduce interference with and damage to surrounding objects.

[0029] Third embodiment 2(b) and 2(c) are schematic diagrams for explaining a protective cover 2000 according to a third embodiment. In the third embodiment, a first end 1810 of a closed loop double string 1800 is fastened to a fixed end 1100, and in a natural state when not in use, the double string 1800 is arranged along one side 1500, and a second end 1820 at the lower end is hooked on a convex body 1451, which is a hook of the fastening end 1450, and fastened so as to be freely attached and detached.

[0030] When using the strap, by removing the second end 1820 at the bottom end of the closed loop double string 1800 from the locking end 1450, the double string 1800 is only fixed at the first end 1810 to the fixed end 1100, so that the position can be freely changed using this as a fulcrum, and it can be held in any manner, such as by hand or through the handle of a bag. The convex body 1451 may be made of lightweight plastic or strong metal foil.

[0031] (Fourth embodiment) In the above embodiment, when the strap 1200 (or the double string 1800) is not used, the strap 1200 is arranged along the outer surface of the one side 1500. However, by providing a space for arranging the strap 1200 on the inner surface of the one side 1500, it is also possible to arrange the strap 1200 inside the protective cover 1000, along the long side of the mobile terminal 1600, in a storage space between the inner surface of the protective cover 1000 and the mobile terminal 1600 when not in use. This can reliably prevent the strap 1200 from interfering with surrounding objects when not in use. This aspect can be applied and implemented in any of the first, second, and third embodiments described above.

[0032] The protective cover 1000 for a mobile terminal of the present invention is a protective cover for a mobile terminal 1600 having a strap 1200 made of an elastic material that can stretch freely along one side 1500, and is characterized in that a fixed end 1100 of one side 1500 to which a first end 1210 of strap 1200 is fixed has an eyelet structure, and a reinforcing material is provided at the engaging end of one side 1500 to which a hook 1300 provided on a second end 1220 of strap 1200 is detachably engaged.

[0033] The strap 1200 made of a stretchable elastic body may be a string that can expand and contract in a spiral (spring shape), and in its natural state, the strap 1200 is arranged parallel to one side 1500 with almost no space between them, thereby improving the storage ability of the strap 1200 and preventing accidents such as getting caught on an unexpected object or being cut at an unexpected time. Also, the strap 1200 made of a stretchable elastic body may be a rubber string of any thickness and any shape (flat, cylindrical, etc.).

[0034] It is preferable that the protective cover 1000 for the mobile terminal covers the entire mobile terminal 1600, and it is particularly preferable that one side edge 1500 of the protective cover 1000 matches a corresponding side edge of the mobile terminal 1600 to provide close contact protection, but this is not limited to this, and various variations in form can be adopted, such as a form that covers only a portion.

[0035] In addition, the first end 1210 of the strap 1200 may be provided with a thin string for fastening that is different from the strap 1200 main body made of a stretchable elastic body so as to facilitate fastening to the fixed end 1100 of the eyelet structure, and the thin string for fastening may be fastened to the fixed end 1100 of the eyelet structure. The second end 1220, which is the other end of the strap 1200, is provided with a hook 1300, which is fastened to the fastening end of one side 1500 in a freely attachable and detachable manner. In this case, it is most preferable that the length of the strap 1200 is such that the position of the hook 1300 can exactly correspond to the position of the fastening end when the strap 1200 is in its natural state without any particular pulling force or the like being applied. Alternatively, it is also preferable that the hook 1300 can be fastened to the fastening end when the strap 1200 is pulled lightly with a very small weak force to apply a slight tension.

[0036] It is preferable that a reinforcing material is provided at the locking end of one side 1500. In general, it is known that the protective cover 1000 of a mobile terminal itself is often made of a relatively soft or flexible material, and may not be very robust against wear, pressure, or friction. On the other hand, the hook 1300 provided at the second end 1220 of the strap 1200 according to the present invention is considered to be attached and detached relatively frequently, and it is preferable to provide an optional reinforcing material in order to minimize and suppress wear of the locking end even if the hook 1300, which is relatively hard, such as made of metal, is attached and detached many times. The reinforcing material may be a cover member that fits the locking end made of plastic or metal, or a reinforcing member that is made by impregnating the material of the locking end itself with a hardened resin and hardening it to reinforce that part.

[0037] In addition, the protective cover 1000 for the mobile terminal 1600 according to the present invention is preferably characterized in that one side 1500 has a length corresponding to the length of the long side of the mobile terminal 1600. The long side of the mobile terminal 1600 is a length that is suitable for the length of the back of the hand in many cases, and is not too short or too long, but just the right length. Therefore, the one side 1500 of the protective cover 1000 also corresponds to the length of the long side of the mobile terminal 1600, so that the length of the strap 1200 arranged along the one side 1500 is also suitable for holding the mobile terminal 1600. The strap 1200 assists or guides the mobile terminal 1600 when holding it, and contributes to maintaining the mobile terminal 1600 in a stable holding state. More specifically, even when holding the mobile terminal 1600 with the left hand 1700, it is easy to hold it so that the screen can be observed, for example, with the screen open.

[0038] Moreover, the protective cover 1000 for a mobile terminal according to the present invention is further preferably characterized in that the second end 1220 of the strap 1200 is provided with a clip 1230 instead of the hook 1300. The clip 1230 is easy to attach and detach, and has a sufficient fastening force to fasten the strap 1200. Since a large pulling force is not applied to the strap 1200 in its natural state, the fixing and holding force of the clip 1230 can fasten the strap 1200 sufficiently stably. Even when the mobile terminal 1600 is held, the fixing force of the clip 1230 can be sufficiently maintained when the strap 1200 guides the back of the hand. Another advantage of the clip 1230 is that it can be made lighter, thinner, and smaller, and is easy to replace.

[0039] Furthermore, the protective cover 1000 for the mobile terminal 1600 according to the present invention is further preferably characterized in that the reinforcing material has a shape in which the locking end 1400 with which the hook 1300 is engaged is concave. When the hook 1300 is locked to the locking end 1400, it is preferable that the locking end 1400 has a hook receiving structure so that the hook 1300 is stably positioned and positioned without shaking. A typical example of this is a concave shape, and by positioning the hook 1300 in the concave part of the locking end 1400, the hook 1300 can be stably positioned without shifting, moving, or swinging. As a result, even if some tensile stress is applied to the strap 1200, the hook 1300 engaged with the concave part is firmly fixed and maintained via the second end 1220 of the strap 1200.

[0040] The protective cover 1000 for the mobile terminal 1600 according to the present invention is a protective cover 1000 for a mobile terminal that includes a double string 1800 that forms a closed loop along one side 1500, and is characterized in that a first end 1810 of the double string 1800 is fixed to a fixed end 1100 of the one side 1500, a second end 1820 of the double string 1800 is detachably engaged with a locking end 1450 of the one side 1500, and the locking end 1450 includes a convex body 1451 for hooking the second end 1820. The convex body 1451 may be in the form of a hook that can hook and lock the second end 1820 that is a closed loop. The double string 1800 may be a stretchable rubber string, or a known strong strap string that is hardly expected to stretch may be used.

[0041] The double string 1800 preferably forms a closed loop with the first end 1810 as a starting point and end point, and therefore has a two-string configuration as a whole. In a natural state, the second end 1820 of the double string 1800 is hooked and locked on the protruding convex body 1451 in a hook configuration, so that the double string 1800 as a whole is positioned and arranged along the one side 1500 without being separated. In this case, it is preferable that there is a sufficient amount of tension between the double string 1800 and the one side 1500 to allow the back of the hand to be inserted. This makes it possible to insert the back of the hand between the double string 1800 and the one side 1500 and hold it.

[0042] Furthermore, the protective cover 1000 for the mobile terminal 1600 according to the present invention is further characterized in that the strap 1200 has a tension such that the back of the handle 1700 of the protective cover 1000 for the mobile terminal 1600 can be inserted between the protective cover 1000 and the strap 1200. This makes it possible to insert the back of the hand between the strap 1200 and the outer edge of the mobile terminal 1600 or its protective cover 1000 when the strap 1200 is in a natural state along one side 1500 of the protective cover 1000, and even if the hand 1700 slips or is about to slip off the fingers, the gripping guide function of the strap 1200 can prevent the mobile terminal 1600 from falling. This function and effect are the same in the case of the double string 1800.

[0043] Furthermore, when hook 1300 or clip 1230 is released and second end 1220 of strap 1200 is released from the engagement, second end 1200 can be engaged and fixed by engaging hook 1300 or clip 1230 with the edge of trousers or a belt, thereby preventing unintentional dropping or loss of mobile terminal 1600 and allowing for safe work and operation.

[0044] The protective covers 1000, 2000, etc. described above are described as preferred embodiments, and are not limited to the forms, sizes, and dimensions shown in the drawings or explanations. They can be freely arranged / modified, added, deleted, transformed, redesigned, adjusted, improved, etc., within the scope of the technology and concept of this invention, taking into account and adding publicly known technology or various technical common sense, well-known technology, and commonly used technology.
