Description

Technology Field

[0001] The present invention relates to a weight holder assembly that facilitates the addition, subtraction, and movement of a movable weight. More specifically, the weight holder, in which the movable weight is held, is equipped with an elastic unit that operates elastically through a fixed coupling of a connecting member and a connecting member. A locking member installed on the outer surface of the elastic unit maintains a protruding state to restrict the movement of the movable weight when no external force is applied, but when a user applies an external force exceeding a certain level to the movable weight and compresses the elastic unit, the protruding state of the locking member elastically relaxes, thereby allowing the movement of the movable weight. Background Technology

[0003] Generally, a weight is attached to a fishing rig that is connected to the main line of the rod and has a hook attached at the bottom. Typically, to ensure that the signal of a fish bite is transmitted quickly, a light main weight is installed at the very bottom, and another weight is placed above it.

[0004] As described above, a fishing rig that uses divided weights is called a split-weight rig. Such rigs are commonly used to increase catch rates by allowing the float to react sensitively. By making the bottom weight, which is the lowest weight, light, the fish feels less resistance due to the lightness of the bottom weight being pulled along with the bait upon a bite. Consequently, the fish swallows the bait without spitting it out. Furthermore, the movement of the bottom weight pulling along simultaneously with the fish's ingestion easily breaks the static inertia of the entire weight system, resulting in a sensitive rise of the float.

[0005] However, the sensitive float response of the aforementioned split sinker rig induces hasty miss-hooks by anglers, while the lightness of the bottom sinker causes the float response to vary depending on changes in the fishing environment, such as changes in water temperature or wind. Consequently, there has been a desire among anglers to adjust the weight of the bottom sinker according to changes in the fishing environment.

[0006] As part of addressing these requirements, Korean Published Patent No. 10-2022-0057394 (published May 9, 2022; "Divided weight rig for easy adjustment of bottom weight") filed by the present applicant provides a weight holder above the bottom weight, which is the main weight, at the lowest end, and configures the system so that an elastic ring made of rubber is installed below the weight holder to selectively restrict the movement of the fine adjustment weight. In this prior art, when a user applies an external force exceeding a certain level to the fine adjustment weight, the fine adjustment weight is configured to move back and forth over the elastic ring, either being supported by the elastic ring on the weight holder or moving over the elastic ring, passing the weight holder, and moving to the bottom weight, which is a component other than the weight holder.

[0007] In the aforementioned prior art, a ring groove in the shape of a rim groove is formed on the outer circumference surface constituting the lower part of the weight holder, and an elastic ring made of rubber is fitted into this ring groove. Here, when there is no external force, the elastic ring protrudes outward from the ring groove due to elastic relaxation, thereby restricting the movement of the fine adjustment weight fitted into the weight holder. In this state, when a user applies an external force greater than a certain amount to the fine adjustment weight, that is, an external force sufficient to cause the elastic ring to contract, the elastic ring contracts into the ring groove, allowing the fine adjustment weight to move. Prior art literature

[0009] Korean Published Patent No. 10-2022-0057394 (Published May 9, 2022) Korean Registered Patent No. 10-2158071 (Registered September 15, 2020) Korean Registered Utility Model No. 20-0494549 (Registered October 28, 2021) Korean Registered Utility Model No. 20-0495181 (Registered March 21, 2022) The problem to be solved

[0010] In the prior art described above, a rubber elastic ring performs the role of restricting or allowing the movement of a weight mounted on a weight holder. However, the rubber elastic ring has the problem that stress accumulates rapidly as the performance of this role accumulates, making it prone to breaking. Furthermore, to prevent malfunction of the elastic ring, screw threads are formed around the ring, and screw threads are also formed on the inner diameter of the ring-shaped fine adjustment weight that travels over the elastic ring. As such, the screw thread structure formed around the elastic ring and in the components that operate in conjunction with it entails a structural problem that can result in a structurally shortened lifespan of the rubber elastic ring.

[0011] Accordingly, the objective of the present invention is to provide a weight holder assembly that guarantees lifespan and performance regardless of the movement of the weight, by adopting the most effective method while considering the advantages, disadvantages, and problems of the aforementioned conventional methods or prior art, and by proposing a configuration that is more economical, simple, and concise, yet distinct from the configuration of prior art, thereby enriching technical diversity.

[0012] In addition, the basic objective of the present invention is to provide a weight holder assembly that not only restricts the movement of a movable weight by fitting it into a weight holder, but also allows the movable weight, which was restricted from movement, to be detached from the weight holder and moved.

[0013] In addition, the objective of the present invention is to provide a weight holder assembly that does not break the existing float balance even when weight is added or removed to the bottom weight positioned at the very bottom, which is positioned below the weight holder in a float-balanced fishing rig.

[0014] In addition, the objective of the present invention is to provide a weight holder assembly that allows the movable weight to be stably fixed without relying on screw coupling.

[0015] In addition, the objective of the present invention is to provide a weight holder assembly in which the weight holder with the movable weight fitted thereon is coupled to the bottom weight, such that the movable weight does not detach from the weight holder even if the fish hooked on the fishing hook shakes after being caught. means of solving the problem

[0017] The weight holder assembly of the present invention for achieving the above-mentioned purpose comprises a weight holder in which a movable weight is held, wherein the weight holder is equipped with an elastic unit that operates elastically through a fixed coupling of a connecting member and a connecting member, and a locking member installed on the outer surface of the elastic unit maintains a protruding state to restrict the movement of the movable weight when there is no external force, but when a user applies an external force exceeding a certain amount to the movable weight and compresses the elastic unit, the protruding state of the locking member elastically relaxes to allow the movement of the movable weight. Effects of the invention

[0019] The sinker holder assembly of the present invention having the above-described configuration has the advantage that, since the sinker holder is pre-inserted and stored during the sinker balance, the weight of the entire fishing rig does not change even if the sinker is moved to match the changing fishing environment during fishing, so the sinker balance is not broken, and the float response can be easily adjusted according to the fishing environment.

[0020] In addition, the present invention has the advantage that even when a movable weight is inserted into the weight holder, the elastic unit provided in the weight holder prevents the movable weight from arbitrarily moving over the elastic unit due to the action of external forces caused by fish, thereby maintaining a stable support state.

[0021] In addition, since the present invention does not require a configuration such as a screw connection to fix the movable weight to the weight holder, the movable weight can be added or removed relatively quickly and easily compared to a screw connection, which has the advantage of increasing convenience of use. Brief explanation of the drawing

[0023] FIG. 1 is a conceptual diagram of the use of a fishing rig according to one embodiment of the weight holder assembly of the present invention. FIG. 2 is an exploded perspective view of a fishing rig to which an embodiment of the weight holder assembly of the present invention is applied. FIG. 3 is a cross-sectional view of a connection according to an embodiment of the weight holder assembly of the present invention. FIG. 4 shows various embodiments of the weight holder assembly of the present invention. Specific details for implementing the invention

[0024] The present invention will be described in detail below using the attached drawings. However, since the attached drawings represent preferred embodiments of the present invention, the scope of the present invention is not limited by these drawings. Furthermore, even if a configuration is essential for implementing the present invention, specific descriptions of configurations that fall under known technology or that a person skilled in the art can easily implement from known technology are omitted.

[0025] Referring to FIG. 1, the term "fishing rig" in the present invention refers to a configuration comprising a weight holder (100) that is submerged in water after the fishing float (2), movable weight (200), bottom weight (3), raft (4), and a fishing hook (6) connected to the raft (4) by a leader line (5), excluding the fishing rod and the fishing float (2) connected to the main line (1) connected to the fishing rod in relation to fishing equipment (in some cases, the fishing hook (6) may be connected to the bottom weight (3) by a leader line (5)). In addition to the above configuration, the weight holder (100) may be combined with a linear member such as a steel wire made of a shape memory alloy or a wire made of a flexible material. Regarding the fishing technique, the rig is based on a split weight rig used for float fishing (also called "bottom fishing") in which the float rises when a fish bites the bait while the bottom weight (3), which is the main weight placed at the bottom, is touching the bottom. However, this is not limited to this, and may include underwater fishing performed without touching the bottom, as well as sea fishing performed in the ocean rather than freshwater.

[0026] As shown in FIGS. 1 to 4, the weight holder assembly (10) of the present invention includes a weight holder (100) in which a movable weight (200) is held by an elastic unit (122) that operates elastically by the fixed coupling of a connecting member (110) and a connecting member (120). A locking member (122b) installed on the outer surface of the elastic unit (122) maintains a protruding state when there is no external force to restrict the movement of the movable weight (200), but when a user applies an external force greater than a certain amount to the movable weight (200) and presses the elastic unit (122), the protruding state of the locking member (122b) is elastically relaxed to allow the movement of the movable weight (200).

[0027] The above weight holder (100) is a rod-shaped structure of a predetermined length and is equipped with an elastic unit (122) that operates elastically through the combination of a connecting member (110) and a connecting member (120), and the movement of the movable weight (200) inserted and moved along the outer surface of the weight holder (100) can be controlled using this elastic unit (122).

[0028] First, the connecting member (110) is provided with an operating part (113) of a predetermined section between a first connecting part (111) and a second connecting part (112) formed at both ends of the rod shape as shown in FIGS. 2 and 3. The first connecting part (111) is inserted into and fixedly coupled to the connecting member (120) to be described later, and the second connecting part (112) is formed exposed to the outside of the connecting member (120).

[0029] Here, the above-mentioned operating part (113) functions as an operating section in which the elastic unit (122) of the connecting member (120), which will be described later, can perform elastic operation. That is, when the connecting member (110) and the connecting member (120) are combined, the operating part (113) is combined in a form that is inserted into the elastic unit (122), so that the elastic unit (122) surrounds the outer circumference of the operating part (113). In this combined arrangement of the operating part (113) and the elastic unit (122), the elastic unit (122) performs elastic operation in response to an external force. To facilitate the elastic contraction and expansion of the elastic unit (122), an operating space (s), which is a predetermined spaced-out space, may be formed between the operating part (113) and the elastic unit (122). The above-mentioned operating space (s) becomes the elastic operating space of the elastic unit (122) in response to the external force.

[0030] In addition, in order to ensure smooth elastic operation through the operating part (113) along with the aforementioned operating space(s), the end of the elastic unit (122) may be formed with a predetermined operating distance (d) from the end of the second connecting part (112) that is exposed to the outside of the elastic unit (122) when there is no external force. The operating distance (d) facilitates the longitudinal elastic operation of the elastic unit (122) when the elastic unit (122) operates elastically using the operating space(s).

[0031] Additionally, the first connecting part (111) and the second connecting part (112) may be formed in a spiral shape and a ring shape, respectively, as shown in FIGS. 2 and 3. However, the first connecting part (111) and the second connecting part (112) are not limited thereto and may be configured in various shapes as shown in FIG. 4.

[0032] For example, the first connecting part (111) may be formed in a non-helical, bald shape as shown in FIG. 4 (a) and (b), in addition to a spiral shape (Fig. 2 and Fig. 3). However, it is preferable that a limiting step (111a), which is a step structure formed with a different diameter, is formed between the first connecting part (111) and the operating part (113). The limiting step (111a) may be a step structure using a groove shape in the middle part of the first connecting part (111) as shown in FIG. 4 (a), or a step structure using a different diameter difference between the first connecting part (111) and the operating part (113) as shown in FIG. 4 (b). This limiting step (111a) is configured to prevent adhesive, which is used to strengthen the fixed connection between the fastening unit (123) of the connecting member (120) to be described later and the first connecting part (111), from flowing into the operating part (113). That is, by expanding the diameter of the end facing the operating part (113) to form the limiting step (111a), the adhesive flowing in through the injection hole (123a) of the fastening unit (123) is blocked by the limiting step (111a) and cannot move toward the operating part (113). Since this prevents the adhesive from flowing into the operating space (s), the elastic operation of the elastic unit (122) through the operating part (113) is made smooth.

[0033] For example, the second connecting part (112) may be formed in a ring shape (Figs. 2 and 3), as well as a rotating ring shape like (A) in Fig. 4, a spiral shape like (B), a linear shape like (C) and (D), and / or a locking wing shape like (E). Thus, the second connecting part (112) is formed to facilitate connection with other components of the fishing rig. The rotating ring shape of Fig. 4 (A) is a configuration capable of relative rotation, and the main line (1) may be directly connected to the rotating ring, or a connecting component made of a flexible material may be connected. The spiral shape of Fig. 4 (B) may be connected to a connecting component having another spiral shape corresponding to it. Among the linear configurations, Fig. 4 (C) may be configured to be advantageous for bending recovery by using a steel wire made of shape memory alloy. Another linear configuration, FIG. 4(D), can be constructed by connecting a hollow woven cord (also known as 'Lilian yarn') manufactured by weaving synthetic fibers, or by connecting surgical steel, which is a metal chain that is freely deformable. In the locking wing type configuration of FIG. 4(E), the end of the second connecting part (112) is provided as a locking wing, and a connecting socket that connects in a one-touch manner is coupled to this locking wing. In the locking wing type configuration, knurling can be formed to prevent slipping during operation.

[0035] Next, as shown in FIGS. 2 and 3, the connecting member (120) has a hole wall portion (120A) formed at one end of the longitudinal end portion of the rod shape, which includes an elastic unit (122) that is elastically operable, and a connecting portion (120B) at the other end portion.

[0036] The above-mentioned hole wall portion (120A) is formed such that one longitudinal end surface of the connecting member (120) is connected to the outside, and this opening is connected to an operating hole (121), which is an internal space in the shape of a hole. This hole wall portion (120A) is divided into an elastic unit (122) and a fastening unit (123).

[0037] The elastic unit (122) constitutes the outer end of the hole wall portion (120A), and a slit (122a) is formed in the longitudinal direction to allow the operating hole (121) to communicate with the outside. The slit (122a) is configured to allow the hole wall portion (120A) to operate elastically by cutting and dividing the hole wall portion (120A). Accordingly, at least two slits (122a) are formed to divide the hole wall portion (120A) into at least two parts. If necessary, multiple slits (122a) may be formed. However, a relatively large number of slits (122a) can impair the durability of the hole wall portion (120A) because it makes the hole wall portion (120A) thinner. Therefore, the number of slits (122a) is preferably 2 to 4.

[0038] Furthermore, the elastic unit (122) restricts the movement of the movable weight (200) when no external force is applied by the user. Then, it allows the movement of the movable weight (200) only when an external force exceeding a certain level occurs, and then restores elasticity. To this end, a catch (122b) is provided on the outer surface of the elastic unit (122) to form an outward protrusion.

[0039] The above-mentioned catch (122b) is formed by the middle portion of the elastic unit (122) protruding outward, and the shape of the outward protrusion may be formed by protruding the entire circumferential surface or only a part thereof. This protrusion includes all forms such as a stepped shape or a protrusion shape in which the diameter expands and then returns to a bent shape. Preferably, the above-mentioned catch (122b) is formed by protruding the middle portion of the circumferential surface of the elastic unit (122) such that the diameter expands outward. Additionally, on both sides of the protruding catch (122b), a guide (122c) in the shape of an inclined surface may be formed such that the diameter gradually decreases and converges to the diameter of the elastic unit (122) which is not expanded at the center. This guide (122c) allows the movable weight (200) to enter the elastic unit (122) smoothly. Even if the movable weight (200) is guided to the guide (122c), if no external force is generated by the user sufficient to cause elastic action on the catch (122b), the movable weight (200) cannot pass over the catch (122b) and movement is restricted.

[0040] The above-mentioned fastening unit (123) constitutes the inner end of the hole wall portion (120A), and the first connecting portion (111) of the connecting member (110) is inserted into the space of the operating hole (121) where the fastening unit (123) is formed and fixedly connected. The inner space of such fastening unit (123) is preferably formed to correspond to the shape of the first connecting portion (111) described above.

[0041] Additionally, an injection hole (123a) communicating with the operating hole (121) is formed through one side of the outer surface of the fastening unit (123). The injection hole (123a) is a through hole into which an adhesive is injected to ensure that the fastening unit (123) and the first connecting part (111) are more effectively fixedly coupled when the first connecting part (111) is inserted into the operating hole (121) and fixedly coupled to the fastening unit (123).

[0042] Through the above configuration, when the first connecting part (111) of the connecting member (110) is fixedly coupled to the fastening unit (123) of the connecting member (120) by a press fit method, an elastic unit (122) that operates elastically is arranged around the operating part (113) of the connecting member (110) through a cut slit (122a). At this time, the elastic unit (122) and the operating part (113) are separated by an operating space (s), and at the same time, the end of the elastic unit (122) is formed separated from the end of the second connecting part (112) by an operating distance (d). Through this configuration, the elastic unit (122) operates elastically.

[0043] When there is no external force applied by the user, the elastic unit (122) restricts the movement of the movable weight (200) by maintaining the protruding state of the locking member (122b) through elastic operation. Then, when an external force is applied by the user pushing the movable weight (200) with strong force, the elastic unit (122) releases the protruding state of the locking member (122b) through elastic operation using the operating space (s) and operating distance (d), thereby allowing the movement of the movable weight (200).

[0044] The above connection part (120B) is plastic and can be formed into a socket type into which a connecting component is inserted, and such a socket type can be formed by deforming its shape in correspondence with the shape of the connecting component. As shown in FIG. 1, a connecting rod of a bottom weight (3) with a slat (4) installed is rotatably connected to the socket-type connection part (120B). However, the connection part (120B) is not limited to a socket type as shown in FIG. 1 to 3, and may be configured as a plug type into which a connecting socket-type component is inserted, as shown in FIG. 4. Such a plug type may be formed as a stepped structure as shown in FIG. 4 (a) or a spiral structure as shown in FIG. 4 (b).

[0046] Meanwhile, the above-mentioned movable weight (200) is configured to be movably inserted into the outer surface of the weight holder (100) as shown in FIGS. 1 to 3, and is capable of moving within the weight holder (100) and also capable of moving out of the weight holder (100).

[0047] The above-mentioned movable weight (200) has a through hole (201) formed in the center. The through hole (201) is formed so that its diameter exceeds that of the configuration of the weight holder (100) excluding the catch (122b) of the elastic unit (122), but is smaller than the protruding diameter of the catch (122b) of the elastic unit (122). Through this, the movable weight (200) has the characteristic that the configuration of the weight holder (100) excluding the catch (122b) can move freely, but its movement is restricted when it encounters the catch (122b). However, even in this case, if the user applies an external force exceeding the elastic modulus of the elastic unit (122), the elastic unit (122) is elastically relaxed by the external force transmitted through the movable weight (200), and the protrusion height of the catch (122b) is lowered, and eventually the movable weight (200) can ride over the lowered protrusion height of the catch (122b) and move.
