Description

Technical Field

[0001] The present invention relates to a device for holding socks in pairs. More specifically, the device for holding socks in pairs can be more easily fastened between a pair of socks, thereby preventing the socks from separating from each other during washing, drying, and storage. During the process of fastening the device between the socks, damage to the socks is minimized. Also, while preventing damage to other laundry items and the washing and drying device during washing and drying, the device can be easily separated from the socks after use. Background Art

[0002] Generally, socks are made in pairs, and a pair of socks must be used simultaneously due to the human body structure.

[0003] Since such socks usually need to be changed daily, multiple pairs of socks are often washed simultaneously. During the washing process, these socks get entangled and mixed together, so there is a problem that they have to be compared and paired one by one after washing.

[0004] In addition, when multiple pairs of the same model and color socks are washed simultaneously, it is difficult to distinguish them, so there is a problem of mixing old socks and new socks and wearing them mismatched.

[0005] For this reason, Korean Registered Utility Model No. 20-0234599 proposes a sock formed with a connecting member for preventing separation, in which a connecting member such as a snap button or a Velcro tape is formed at the opposite ankle portions of a pair of socks to prevent separation during washing.

[0006] However, in Korean Registered Utility Model No. 20-0234599, when a large amount of other laundry items and socks are washed together, there is a problem that the connecting members that are easily combined with each other due to the entanglement of the socks and other laundry items during the washing process are likely to separate.

[0007] In addition, in Korean Registered Utility Model No. 20-0234599, during the manufacturing process of socks, since it is necessary to attach a connecting member such as a snap button or a Velcro tape to the ankle portion of the socks, not only the manufacturing cost of the socks increases, but also when the life of the socks ends, the connecting members attached to the socks are discarded together, so there is a problem of unnecessary waste of resources.

[0008] In addition, in Korean Registered Utility Model No. 20-0234599, during wearing, the connecting member may come into contact with the human body and cause inconvenience. During the washing and drying process, strong pulling force is repeatedly applied to the portion where the connecting member is attached, so there may be problems such as detachment, deformation, and damage of the connecting member, resulting in a deterioration in aesthetics.

[0009] Meanwhile, a device or appliance for fixing a pair of socks so that they do not separate from each other is a matter that anyone can generally think of and can actually be implemented in various forms.

[0010] However, without damaging the fibers or the washing and drying devices, in order to simultaneously achieve a structure that anyone can easily operate and is easy to separate for repeated use, an elaborate structure and creative ideas that require reasonable operation using appropriate materials are needed.

[0011] In particular, it is not easy to implement an elaborate operating mechanism that can effectively perform washing and drying through a structure that anyone can easily insert and pull out but is not easily pulled out automatically.

[0012] On the other hand, many patent applications and commercially available products have been developed abroad for devices or appliances for fixing socks so that they do not separate from each other, but products that can simultaneously meet the convenience brought by simple operation, prevent damage to fibers and devices, and have a reusable structure have not been developed. Therefore, there are actually almost no widely commercialized, practical, and efficient products.

[0013] For example, U.S. Registered Patent No. 4,045,844 and U.S. Registered Patent No. 5,440,791 disclose a device that uses a plastic clip to hold a pair of socks, and products in the form of plastic clips can also be found (http: / / www.amazon.com / Alcrea%C2%AE-Washing-Directly-Pairing-Complete / dp / B0081YWQPW / ref=sr_1_5?keywords=sock+clips+for+laundry&qid=1701822700&sr=8-5). It is difficult to clean the part of the sock held by the plastic clip, and the relatively hard plastic is exposed to the outside. Therefore, during the washing and drying processes, not only will other laundry items be damaged, but it is also easy to separate from the laundry items, resulting in problems such as damage to the washing and drying devices or malfunction.

[0014] In addition, in International Publication Patent WO1998 / 023806 and International Publication Patent WO2000 / 064312, devices for punching various forms of holes in a plastic plate to insert two socks for fixation are disclosed. Products that form grooves in a plastic circular plate to insert two socks for fixation can also be found (https: / / www.amazon.com / Helping-Hand-Paired-Washer-Laundry / dp / B00SS1UFT4). For the above devices and products, the socks are inserted and removed by squeezing one side of the socks to insert them into the holes or grooves. In this process, not only do problems such as sock damage and unclean washing of the squeezed area occur, but there is still a problem that the relatively hard plastic is exposed to the outside, thus damaging other laundry items during the washing and drying processes.

[0015] At the same time, products can be found that fix two socks by inserting both ends of a rubber band into a spherical support made of plastic and fixing them (https: / / www.amazon.com / NEW-Homeffect-Laundry-Together-Organizer / dp / B09N2XTP6T). This not only causes the problem of unclean washing of the sock parts tied by the rubber band, but also the spherical support made of plastic is exposed to the outside, and there is still a problem of damaging other laundry items.

[0016] Due to the above problems, the above products are not applicable to households in many cases, so there are limitations in being difficult to be commercially popularized. In fact, except for special cases, they are not widely commercially used.

[0017] For the above reasons, there is an urgent need to develop products that can simultaneously meet the convenience brought by simple operation, prevent damage to fibers and devices, and have a reusable structure.

[0025] Technical Problem

[0026] The present invention is proposed to solve the above problems, and the object of the present invention is to provide a fastener for preventing socks from separating, which can be more easily fastened between a pair of socks to prevent the socks from separating from each other during washing, drying and storage, minimize damage to the socks during the process of fastening between the socks, prevent damage to other laundry items and the washing and drying devices during washing and drying, and can be easily separated from the socks after use.

[0027] Technical Solution

[0028] According to the present invention for achieving the above object, there is provided a fastener for preventing socks from separating, which is fastened between a pair of socks to prevent the pair of socks from separating from each other, and includes: an insertion part that penetrates through a pair of socks and is supported on one side of any one of the socks, the insertion part including a fastening pin having a pointed front end and a pair of elastic expansion rods that are respectively extended rearward from the rear end of the fastening pin and are spaced apart from each other, and the respective rear ends of the extended elastic expansion rods are connected to each other; a fastening part that extends from the rear of the insertion part; and a support part that is formed at the end of the extended fastening part and is supported on one side of the other sock.

[0029] Wherein, the angle between the front ends of the pair of elastic expansion rods that are spaced apart from each other is formed to be smaller than the angle between the rear ends, and the length of the rear end part is shorter than the length of the front end part, so the region with the maximum spacing distance is adjacent to the fastening part.

[0030] In addition, the angles between the front ends and the rear ends of the pair of elastic expansion rods that are spaced apart from each other are formed to be acute angles, and the inner sides facing each other are flat.

[0031] Advantages of the Invention

[0032] According to the present invention as described above, since it is easier to fasten between a pair of socks to prevent the socks from separating from each other during washing, drying, and storage, the socks can be conveniently and effectively managed without the need for a process of comparing and pairing them one by one, thus providing convenience to the user.

[0033] In addition, the present invention can minimize damage to the socks during the process of fastening between the socks, and can prevent damage to other laundry items and the washing and drying apparatus during washing and drying, thereby preventing additional cost losses caused thereby.

[0034] Moreover, the present invention is easy to separate from the socks after use for reuse, so unnecessary waste of resources can be prevented.

[0035] In addition, the present invention is made of a polypropylene material, has firmness when pressurized or restored, and has softness to such an extent that it does not cause damage to fibers or the human body. Thus, it is not only excellent in terms of stability, but also not easily damaged by heat or deformed at high temperatures during the drying process. Therefore, from the perspective of reuse, it can provide excellent durability.

[0036] Meanwhile, since the present invention is disposed inside each sock in a fastened state without being exposed to the outside, during washing, drying, and storage, there will be no problem of damage caused by the fastener 1. And, although during the washing and drying process, due to the additional external force of being wound around other laundry items, any one sock may fall off in the direction of the elastic expansion rod 12, the other sock remains in a fastened state by means of the support portion and does not separate from the sock. Therefore, damage or malfunction of the washing and drying apparatus caused by the separated fastener can be prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Next, the present invention will be described in more detail with reference to the accompanying drawings. It should be noted that the same constituent elements are denoted by the same reference numerals wherever possible in the drawings. In addition, detailed descriptions of well-known functions and configurations that unnecessarily obscure the gist of the invention are omitted.

[0046] Figure 1 is a perspective view of a fastener for preventing sock separation according to an embodiment of the present invention, Figure 2 is a top view of a fastener for preventing sock separation according to an embodiment of the present invention, Figure 3 is a schematic diagram of a state in which the elastic expansion rods of a fastener for preventing sock separation according to an embodiment of the present invention are closely attached to each other.

[0047] Refer to Figures 1 to 3 , a fastener 1 for preventing sock separation according to an embodiment of the present invention is fastened to an adjacent part of a pair of socks to prevent the pair of socks from separating from each other during washing, drying, and storage. The fastener 1 for preventing sock separation includes: an insertion part 10, a fastening part 20, and a support part 30.

[0048] After the insertion part 10 is inserted into the adjacent part of a pair of socks, it is supported together with the support part 30 described later on the inner surface side of each sock, and functions to prevent the pair of socks from separating from each other, and includes a fastening pin 11 and an elastic expansion rod 12.

[0049] The front end of the fastening pin 11 is formed to be pointed so that the insertion part 10 can be easily inserted into the adjacent part of a pair of socks.

[0050] The elastic expansion rods 12 are formed in a pair from a material having elastic restoring force, extend rearward from the rear end of the fastening pin 11 while being spaced apart from each other, and are formed such that the respective rear ends extending are connected to each other.

[0051] More specifically, the elastic expansion rod 12 has a spindle-shaped structure, that is, the front end portions open in a direction away from each other as they go further back from the fastening pin 11, and then the rear end portions converge in a direction approaching each other. That is, it has a shape in which the region between the front end and the rear end is bent in a direction away from each other.

[0052] In the case where the elastic expansion rods 12 are inserted into the adjacent part of a pair of socks through the fastening pin 11 as described above, the user presses them with the thumb and index finger to make them closely fit to each other, as Figure 3As shown, as the curvature of the bend decreases and it deforms into a flat straight form, it can more easily penetrate between the microfibers that make up the socks. Therefore, it can not only be easily fastened between a pair of socks, but also minimize damage to the socks during the fastening process.

[0053] In addition, after the elastic expansion rod 12 passes through the adjacent parts of a pair of socks, when the user releases the pressing force, it returns in a mutually separated direction. As the curvature of the bend increases, it supports one side of the inner surface of any one sock, and together with the support part 30 that supports the other side of the inner surface of the other sock described later, it prevents the pair of socks from separating from each other.

[0054] In particular, the elastic expansion rod 12 as Figure 2 shown has the following structure: the front end included angle α that is mutually separated is smaller than the rear end included angle β, and the length b of the rear end part is shorter than the length a of the front end part, so that the region with the maximum separation distance d is adjacent to the fastening part 20 described later.

[0055] Through the above structural features, in the state where the elastic expansion rod 12 becomes flat as the curvature of the bend decreases, it can more easily be inserted into the adjacent parts of a pair of socks. After the insertion is completed, in the state of returning in a mutually separated direction, as the region with the maximum separation distance d is adjacent to the fastening part 20, it can more thoroughly prevent the socks from falling off in the direction of the elastic expansion rod 12.

[0056] At the same time, the included angles α and β at the mutually separated front end and rear end of the elastic expansion rod 12 form acute angles, and the mutually facing inner side surfaces are formed into flat shapes. Therefore, when the user presses the elastic expansion rod 12 in a mutually approaching direction, the front end and the rear end do not split and the mutually facing inner side surfaces are closely attached, and it can more easily be deformed into a flat shape with a reduced curvature of the bend.

[0057] In addition, each outer side surface of the elastic expansion rod 12 is formed into a hemispherical shape. When it is pressed by the user so that the inner side surfaces are in close contact with each other, as shown in the enlarged view of Figure 3 , it becomes a strip shape with a circular cross-section and a long length, so that it can easily pass between the microfibers of the socks with minimal resistance.

[0058] The fastening part 20 is formed to extend rearward from the rear end of the elastic expansion rod 12.

[0059] This fastening part 20 is provided between the aforementioned insertion part 10 and the later-described support part 30 to provide a region where the adjacent parts of a pair of socks are closely arranged, and is formed to have a short length, so as to avoid the distance between the arranged pair of socks from becoming far, and there will be no problem of entanglement or separation from other socks fastened by the fastener according to the present invention.

[0060] The support portion 30 is formed in a substantially long trapezoidal strip shape and is formed at the end portion where the fastening portion 20 extends, and supports one side of the inner surface of the other sock. Together with the elastic expansion rod 12 that supports one side of the inner surface of any sock, it prevents a pair of socks from separating from each other.

[0061] The length direction of this support portion 30 is set in a direction perpendicular to the separating direction of the elastic expansion rod 12, and the inclined surfaces provided on both sides in the width direction are inclined in the rear outer direction.

[0062] With the above structure, the user can easily press the elastic expansion rod 12 in the direction of being closely attached to each other while holding the support portion 30 between the thumb and the index finger, thus providing ease of operation.

[0063] The aforementioned fastener 1 for preventing sock separation according to an embodiment of the present invention is made of polypropylene material, has firmness when pressurized or restored, and has softness to the extent that it does not cause damage to fibers or the human body. Thus, it is not only excellent in terms of stability but also not easily damaged or deformed by high-temperature heat during the drying process. Therefore, from the perspective of repeated use, it can provide excellent durability.

[0064] Figures 4 to 6 It is a schematic diagram for explaining the operation of the fastener for preventing sock separation according to an embodiment of the present invention.

[0065] First, as Figure 4 shown, the user presses the spindle-shaped elastic expansion rod 12 that is bent in the direction of separating from each other in the direction of approaching each other, thereby changing it into a flat shape with a reduced bending curvature.

[0066] Then, as Figure 5 shown, when the user inserts the elastic expansion rod 12 and the fastening pin 11 together through and into the adjacent part between a pair of socks, the adjacent parts of the pair of socks are arranged in a state of being penetrated by the fastening portion 20.

[0067] At this time, if the user releases the pressure applied to the elastic expansion rod 12, the elastic expansion rod 12 will return to the spindle shape that is bent in the direction of separating from each other, so that it is supported on one side of the inner surface of any sock, and the other side of the inner surface of the other sock is supported by the support portion 30. Thus, it is possible to prevent a pair of socks arranged in a state of being penetrated by the fastening portion 20 from falling off in the direction of the elastic expansion rod 12 and the support portion 30.

[0068] Therefore, as Figure 6 shown, the adjacent parts of a pair of socks can be kept in a firmly fastened state by the fastener 1 for preventing sock separation according to the present invention, thereby preventing a pair of socks from separating from each other.

[0069] Meanwhile, for the sock separation prevention fastener 1 according to an embodiment of the present invention, when separating the sock penetrated by the fastened part 20, the elastic expansion rod 12 can also be pressed in the direction of approaching each other to be deformed into a flat shape with a reduced bending curvature by the above method, so that the sock can be easily separated from the fastened part 20.

[0070] In addition, for the sock separation prevention fastener 1 according to the present invention, as Figure 6 shown, since it is arranged inside each sock in the fastened state and is not exposed to the outside, there will be no problem of being damaged by the fastener 1 during washing, drying and storage.

[0071] Meanwhile, for the sock separation prevention fastener 1 according to the present invention, during the washing and drying process, due to the additional external force of being wound around other laundry, any one sock may fall off in the direction of the elastic expansion rod, but the other sock is kept fastened by the support part and will not separate from the sock. Therefore, it is possible to prevent damage or malfunction of the washing and drying device due to the separated fastener.

[0072] As described above, the sock separation prevention fastener 1 according to the present invention is fastened to the adjacent parts of a pair of socks to more thoroughly prevent the pair of socks from separating from each other during washing, drying and storage, so that there is no need for the process of comparing and pairing the socks one by one, thus providing convenience for users.

[0073] Moreover, since it is easy to separate from the sock after use, it can be reused, thereby preventing unnecessary waste of resources.

[0074] Although the present invention has been described in connection with the preferred embodiments, various modifications or variations can be made without departing from the spirit and scope of the invention. Therefore, the appended claims will include such modifications or variations that belong to the spirit of the present invention.
