Description

[Technical Field]

[0001] This invention relates to a carabiner having a hook portion for hanging an item, and a swinging member that elastically switches between open and closed positions at the opening of the hook portion where the item is attached. [Background technology]

[0002] Conventionally, carabiners for hanging objects have come in various shapes, and some have a spring part at the opening of the hook part that hangs the object, which elastically switches between open and closed positions.

[0003] For example, the locking double carabiner disclosed in Patent Document 1 includes a main body and first and second hooks oriented on first and second sides of the main body. It also includes a first gate attached to the main body and oriented to close the first hook, and a second gate oriented to close the second hook. The first and second gates are provided with sliding locks. The sliding locks have a locked position positioned within a notch in the main body and an unlocked position positioned away from the notch. This locking double carabiner involves placing an item in each of the first and second hooks on the main body, closing the gates, and then sliding the sliding lock to the locked position within the notch. This prevents the gates from opening accidentally. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2015-516546 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned background art, the gate is formed by bending a metal rod into a long, thin U-shape and bending both ends into short L-shapes. The L-shaped ends are inserted into mounting holes formed in the main body. This makes the mounting holes conspicuous and unsightly. The gate is a loop-shaped spring, and if something gets caught on the loop and a strong force is applied, it may accidentally come off. Furthermore, the gate is thicker than the main body, creating unevenness and making it prone to getting caught on other objects. Furthermore, the sliding lock is slidably attached to the gate and is conspicuous. Additionally, the gate consists of three components: the main body and two gates, making it expensive.

[0006] This invention was made in consideration of the problems of the above-mentioned background art, and aims to provide a carabiner that is easy to assemble, can securely hang items, will not open accidentally, and has a good appearance. [Means for solving the problem]

[0007] The present invention is a carabiner consisting of a main body having multiple openings and a swinging member that closes the multiple openings, wherein the main body consists of a first hook portion and a second hook portion, each having an opening formed therein, and a connecting portion that connects the first hook portion and the second hook portion together and holds a part of the swinging member, and the swinging member is a carabiner that integrally comprises a closing portion that closes the openings of the main body and a spring portion that biases the closing portion, and the spring portion is held by the connecting portion of the main body.

[0008] The spring portion has a curved portion, one end of which is continuous with the closing portion and the other end of which is held by the connecting portion of the main body. The main body and the swinging member are provided symmetrically with respect to the center of the connecting portion of the main body.

[0009] The spring portion is a spring that is long in one direction, the oscillating member has one spring portion, the closing portion is integrally formed at both ends of the spring portion via the curved portion, a locking portion is provided at the tip end of each closing portion opposite the curved portion, the oscillating member is formed in a point-symmetric shape at the middle of the longitudinal direction of the spring portion with respect to a central axis that intersects with a plane along the bending direction of the spring portion, a protrusion is provided at the tip end of the first hook portion and / or the second hook portion, and the tip end of the closing portion and the tip end of the first hook portion and / or the second hook portion engage with each other by combining the locking portion and the protrusion.

[0010] The carabiner is made of two parts: the main body and the swinging member, and the locking member has a hook at the tip of each closing part, and the protrusion of the first hook part and / or the second hook part has a hook-receiving recess at the tip.

[0011] The connecting portion of the main body is provided with an accommodating space for accommodating and holding the spring portion of the oscillating member. The oscillating member has an oscillating central axis supported by the connecting portion of the main body, and the oscillating central axis is provided at a predetermined distance from an extension line of the spring portion of the oscillating member in the longitudinal direction.

[0015] An embodiment of the present invention will now be described with reference to the drawings. Figures 1 to 10 show one embodiment of the present invention, in which a carabiner 10 of this embodiment is provided with a main body 16 equipped with a first hook portion 12 and a second hook portion 14 for attaching an item. The main body 16 is integrally molded from, for example, a synthetic resin. Note that if a resin with spring properties is used for the swinging member 40 (described later), the material of the main body 16 can be freely selected, and it can be any material, including a non-spring material or recycled metal or resin.

[0016] The main body 16 will be described with reference to Figures 7 and 8. The main body 16 is provided with a connection portion 18 that integrally connects the first hook portion 12 and the second hook portion 14 and holds a part of a swinging member 40, which will be described later. The connection portion 18 of the main body 16 is formed in the shape of a parallelogram plate and has a pair of parallel sides, with side edges 18a and 18b being a pair of shorter sides and side edges 18c and 18d being a pair of sides that are, for example, about twice as long as the shorter sides.

[0017] The connecting portion 18 is formed by two parallelogram-shaped plates of the same shape, arranged parallel to each other with a predetermined distance between them. The side edges 18a, 18b, 18c, and 18d face each other with a predetermined distance between them. The corners enclosed by the side edges 18a and 18c and the corners enclosed by the side edges 18b and 18d form acute angles. The area near these acute angles forms a connecting portion 20, which has a thickness sufficient to fill the gap between the pair of plates and connects the pair of plates. The space between the pair of plates, separated by a predetermined distance, is an accommodation space 22 that accommodates the swinging member 40 (described later). The side edges 18a, 18b, 18c, and 18d other than the connecting portion 20 are open and communicate with the accommodation space 22. The thickness direction of the plates of the connecting portion 18 corresponds to the thickness direction of the main body 16. As described later, the main body 16 is formed point-symmetrically with respect to a virtual central axis that penetrates the connecting portion 18 in the thickness direction.

[0018] In connecting portion 18, a corner surrounded by side edge portions 18a and 18d and a corner surrounded by side edge portions 18b and 18c form an obtuse angle, and a pair of retaining portions 24 that protrude with a predetermined thickness are formed near each of these obtuse-angled corners on inner surface 18e that faces storage space 22. The outer shape of retaining portion 24 parallel to inner surface 18e is approximately rectangular.

[0019] Of the pair of retaining portions 24, retaining portion 24a, which is provided at a corner surrounded by one of side edges 18a and 18d, has an outer shape surrounded by side edges 18a and 18d, one side intersecting side edge 18a at a substantially right angle at a position slightly away from the corner, and another side intersecting side edge 18d at a position slightly away from the corner and substantially parallel to side edge 18a. A bearing recess 26 is provided at a predetermined depth on a surface of retaining portion 24a substantially parallel to inner surface 18e. Bearing recess 26 is groove-shaped and communicates with side edge 18a at a substantially right angle, and is open to the outside of main body 16. The end of bearing recess 26 opposite side edge 18a is semicircular and bulges outward from side edge 18a. The portion of the bearing recess 26 that communicates with the side edge 18a widens toward the inner surface 18e and also communicates with the inner surface 18e. The holding portions 24a are formed on each of the pair of plates that form the connecting portion 18, and face each other within the accommodation space 22.

[0020] The other retaining portion 24b, located at the corner surrounded by the side edges 18b and 18c, has the same shape as the retaining portion 24a, and is surrounded by the side edges 18b and 18c, one side intersecting the side edges 18b at a substantially right angle at a position slightly away from the corner, and another side intersecting the side edge 18c at a position slightly away from the corner and substantially parallel to the side edge 18b. The retaining portion 24b also has a bearing recess 26 formed at a predetermined depth. The bearing recess 26 is a groove-shaped recess that connects to the side edge 18b at a substantially right angle, and the end opposite the side edge 18b is semicircular and bulges outward. The portion of the bearing recess 26 that connects to the side edge 18b widens toward the side edge 18c and also connects to the side edge 18c. Like the holding portion 24a, the holding portion 24b is formed on each of a pair of plates that form the connecting portion 18, and faces each other in the accommodation space 22.

[0021] A first hook portion 12 protrudes from the side of side edge 18c of connecting portion 18. First hook portion 12 is formed in a deformed U-shaped rod shape, and base end 12a, which is one longitudinal end, is continuous with connecting portion 20 on the side edge 18c side of connecting portion 18. First hook portion 12 protrudes outward from connecting portion 20 along an extension of side edge 18a, bends at a predetermined position substantially parallel to side edge 18c, i.e., at an acute angle, and then bends toward connecting portion 18, also substantially parallel to side edge 18b, i.e., at an obtuse angle, at a position on the extension of side edge 18b, so that tip end 12b of first hook portion 12 reaches a position spaced a predetermined distance from connecting portion 18. The space between tip end 12b of first hook portion 12 and connecting portion 18 forms opening 28 for inserting an item into first hook portion 12. The outer surface of the tip portion 12b, which is the outer side of the U-shape of the first hook portion 12, is located on an extension line of the side edge portion 18b.

[0022] Engagement claws 30 are provided on the tip portion 12b. The engagement claws 30 are formed in a thin shape with a cross section smaller than a cross section intersecting the longitudinal direction of the tip portion 12b. A pair of engagement claws 30 are provided, spaced apart in the thickness direction, and protrude from the tip portion 12b toward the connecting portion 18. Each engagement claw 30 is formed of a side surface 30a flush with the outer surface located on an extension of the side edge portion 18b near the tip portion 12b, a side surface 30b opposite the outer surface 30a, and side surfaces 30c and 30d located between the side surfaces 30a and 30b. The side surface 30c is the outer surface of the pair of engagement claws 30 that are spaced apart from each other, and the side surface 30d is the inner surface of the pair of engagement claws 30 that face each other. The side surface 30b is located closer to the outer surface 30a than an extension of the inner surface of the U-shape of the tip portion 12b. As a result, the inner surface 30b is recessed from the tip end portion 12b, and the recessed space becomes the accommodation portion 32 that accommodates the abutment portion 50 of the closing portion 42 of the swinging member 40, which will be described later.

[0023] Furthermore, the side surface 30c of each engaging claw 30 is flush with the side surface near the tip end 12b, and the side surface 30d faces a space at a predetermined distance, which serves as a storage section 34 in which the locked portion 52 of the closing portion 42 of the swinging member 40 is stored. The storage section 34 communicates with the storage section 32. A protrusion 36 that protrudes into the storage section 34 is provided on the side surface 30d of each engaging claw 30 at a tip portion away from the tip end 12b of the first hook portion 12. A hook portion storage recess 38 is formed on the surface of the protrusion 36 facing the tip end 12b, along the side edge located opposite the storage section 32. The hook portion storage recess 38 stores the hook portion 52a of the locked portion 52 of the closing portion 42 of the swinging member 40.

[0024] A second hook portion 14, which is point-symmetrical to the first hook portion 12, protrudes from the side of the side edge 18d of the connecting portion 18. The second hook portion 14 is formed in a deformed U-shaped rod, and its base end 14a, which is one longitudinal end, is continuous with the connecting portion 20 on the side edge 18d side of the connecting portion 18. The second hook portion 14 protrudes outward from the connecting portion 20 along an extension of the side edge 18b, bends at a predetermined position substantially parallel to the side edge 18d, i.e., at an acute angle, and then bends toward the connecting portion 18, also substantially parallel to the side edge 18a, i.e., at an obtuse angle, at a position on the extension of the side edge 18a, so that the tip end 14b of the second hook portion 14 reaches a position spaced a predetermined distance from the connecting portion 18. The space between the tip end 14b of the second hook portion 14 and the connecting portion 18 forms an opening 28 for inserting an item into the second hook portion 14. The outer surface of the tip portion 14b, which is the outer side of the U-shape of the second hook portion 14, is located on an extension line of the side edge portion 18a.

[0025] The tip portion 14b is provided with an engagement claw 30 having the same shape as the tip portion 12b. The engagement claws 30 are formed in a thin shape with a cross section smaller than a cross section intersecting the longitudinal direction of the tip portion 14b. A pair of engagement claws 30 are provided, spaced apart in the thickness direction, and protrude from the tip portion 14b toward the connecting portion 18. Each engagement claw 30 is formed of a side surface 30a flush with the outer surface located on an extension of the side edge portion 18a near the tip portion 14b, a side surface 30b opposite the outer surface 30a, and side surfaces 30c and 30d located between the side surfaces 30a and 30b. The side surface 30c is the outer surface of the pair of engagement claws 30 that are spaced apart from each other, and the side surface 30d is the inner surface of the pair of engagement claws 30 that face each other. The side surface 30b is located closer to the outer surface 30a than an extension of the inner surface of the U-shape of the tip portion 14b. As a result, the inner surface 30b is recessed from the tip end 14b, and the recessed space becomes the accommodation portion 32 that accommodates the abutment portion 50 of the closing portion 42 of the swinging member 40, which will be described later.

[0026] Furthermore, the side surface 30c of each engaging claw 30 is flush with the outer surface near the tip end 14b, and the side surface 30d faces a space at a predetermined distance, which serves as a storage section 34 in which the locked portion 52 of the closing portion 42 of the swinging member 40 is stored. The storage section 34 communicates with the storage section 32. A protrusion 36 that protrudes into the storage section 34 is provided on the side surface 30d of each engaging claw 30 at a tip portion away from the tip end 14b of the second hook portion 14. A hook portion storage recess 38 is formed on the surface of the protrusion 36 facing the tip end 14b, along the side edge located opposite the storage section 32. The hook portion storage recess 38 stores the hook portion 52a of the locked portion 52 of the closing portion 42 of the swinging member 40.

[0027] The carabiner 10 is provided with one swinging member 40 that closes the two openings 28 of the main body 16. The swinging member 40 will be described with reference to Figures 9 and 10. The swinging member 40 integrally comprises a closing portion 42 that closes the openings 28 of the main body 16 and a spring portion 44 that biases the closing portion 42. The swinging member 40 is integrally molded from a synthetic resin with spring properties.

[0028] The spring portion 44 of the rocking member 40 is rod-shaped and elongated in one direction. The cross-sectional shape intersecting the longitudinal direction is rectangular, and the longitudinal direction of the rectangle coincides with the thickness direction of the main body 16 when attached to the main body 16. It easily elastically deforms when a certain amount of force is applied by hand. The spring portion 44 is bent into a Z-shape, consisting of a straight line portion 44a in the middle and curved portions 44b connected to both ends of the straight line portion 44a. The curved portions 44b are formed by bending the straight line portion 44a at an acute angle, and the pair of curved portions 44b are bent in directions away from each other on the same plane including the straight line portion 44a. The plane on which the straight line portion 44a and the curved portions 44b are located intersects with the thickness direction of the main body 16 when the rocking member 40 is attached to the main body 16. The corners of the pair of curved portions 44b are rounded. The curved portions 44b are linear near the ends opposite to the straight portions 44a, and these straight portions of the pair of curved portions 44b are substantially parallel to each other.

[0029] A closing portion 42 is provided at the end of each curved portion 44b opposite the straight portion 44a. The closing portion 42 is rod-shaped and long in the direction of the extension of the straight portion of the end of the curved portion 44b. The closing portion 42 is formed of a base end 42a, which is one end in the longitudinal direction, an inner surface 42b that continues to the inside of the corner of the curved portion 44b, an outer surface 42c opposite the inner surface 42b, and a tip end 42d, which is located opposite the base end 42a and intersects the outer surface 42c at a substantially right angle. The base end 42a, which is one end in the longitudinal direction of the closing portion 42, continues to the end of the curved portion 44b of the spring portion 44, and the boundary with the curved portion 44b forms a step.

[0030] The longitudinal direction of the closure portion 42 is a length that closes the opening 28 of the main body 16. The cross-sectional shape intersecting the longitudinal direction is rectangular, and the thickness direction, which coincides with the thickness direction of the main body 16 when attached to the main body 16, is smaller than the tip 12b of the first hook portion 12 and the tip 14b of the second hook portion 14, and slightly larger than the thickness direction of the spring portion 44. The length in the width direction intersecting the thickness direction, i.e., the distance between the inner surface 42b and the outer surface 42c, is longer than the thickness direction, is approximately the same as the width of the tip 12b of the first hook portion 12 and the tip 14b of the second hook portion 14, and is wider than the width direction of the spring portion 44.

[0031] The outer contour of the step, which is the boundary between the base end 42a and the curved portion 44b, viewed from the thickness direction is connected to the inner surface 42b and the outer surface 42c, and the intermediate portion forms a curve that bulges out toward the center of the closed portion 42, and the position where it connects to the outer surface 42c is farther from the tip end 42d than the position where it connects to the inner surface 42b. In other words, it bulges out toward the curved portion 44b.

[0032] The portion between the curved portion 44b of the spring portion 44 and the base end 42a forms the mounting portion 44c, where the holding portion 24 of the connection portion 18 of the main body 16 is located when the spring portion 44 is attached to the main body 16. The mounting portion 44c is flush with the curved portion 44b, i.e., it has the same thickness as the curved portion 44b but is thinner than the closing portion 42. When viewed from the thickness direction, the mounting portion 44c has a fan-like shape surrounded by a straight line extending along the extension of the inner surface 42b, a straight line substantially parallel to the tip end 42d, and the curved base end 42a. A swing center shaft 46 is integrally formed at the center of the fan-like shape. The swing center shaft 46 is cylindrical with a central axis substantially parallel to the thickness direction and protrudes in the thickness direction from both sides of the mounting portion 44c. The swing center shaft 46 is spaced apart from the base end 42a of the closing portion 42. The pivot shaft 46 is rotatably held in a bearing recess 26 formed in the holding portion 24 of the main body 16 .

[0033] The curved portion 44b is connected to the outer surface 42c side of the closure portion 42 relative to the swing central axis 46. In other words, the swing central axis 46 is located at a position a predetermined distance away from the inner surface 42b side with respect to an extension of the center line of the closure portion 42 between the inner surface 42b and the outer surface 42c. As a result, the force that moves the closure portion 42 by the spring portion 44 acts at a position away from the swing central axis 46 toward the outer surface 42c of the closure portion 42. The curved portion 44b gradually becomes wider as it approaches the closure portion 42, and the connection strength is high.

[0034] A locking recess 48 is provided in the portion of the closure portion 42 that is continuous with the tip 42d, on the inner side surface 42b, the outer side surface 42c, and the side surface 42e that intersects with the tip 42d, and is thin and formed in the thickness direction of the closure portion 42. The locking recess 48 is formed in a rectangular shape and connected to the outer side surface 42c and the tip 42d, and the thin remaining portion between the inner side surface 42b is an abutting portion 50 that is inserted into the accommodating portion 32 of the tip 12b of the first hook portion 12 or the tip 14b of the second hook portion 14 of the main body 16 and abuts against the engaging claw 30 from the inner side surface 30b. A locked portion 52 is formed in the locking recess 48, with a predetermined width and a predetermined height that is lower than the abutting portion 50, along the tip 42d. The locked portion 52 is inserted into the accommodating portion 34 of the tip portion 12b of the first hook portion 12 or the tip portion 14b of the second hook portion 14 of the main body 16, and is positioned on the engaging claws 30. A hook portion 52a that protrudes toward the base end portion 42a along the outer surface 42c is formed continuously at the portion of the locked portion 52 that is continuous with the outer surface 42c. The bottom portion of the engaging recess 48 other than the locked portion 52 and the hook portion 52a is shaped like a thin plate that follows the center of the thickness of the outer surface 42c, and is inserted between the protrusions 36 of the pair of engaging claws 30 of the main body 16, and is positioned.

[0035] The swinging member 40 bends in a direction intersecting the thickness direction of the spring portion 44, and is provided in a point-symmetrical shape with respect to an imaginary central axis that intersects with a plane along the bending direction at the middle of the longitudinal direction of the spring portion 44, and has shapes rotated 180° from each other. Note that the main body 16 is also provided in a point-symmetrical shape with respect to an imaginary central axis that intersects with the thickness direction at the center of the connecting portion 18, and has shapes rotated 180° from each other.

[0036] Next, we will explain how to assemble the carabiner 10 of this embodiment. Align the thickness direction of the main body 16 and the swinging member 40, and insert the tip 42d of one of the closing sections 42 of the swinging member 40 into the storage space 22 from the side edge 18d of the connecting section 18, and then extend it from the side edge 18b. At this time, the swinging member 40 is stretched and the angle of the curved section 44b is elastically deformed greatly until the swinging center axle 46 also extends from the side edge 18d, and is then pulled out and inserted from the side edge 18b into the bearing recess 26 of the holding section 24b. The swinging center axle 46 of the other closing section 42 is also inserted from the side edge 18a into the bearing recess 26 of the holding section 24a. Then, the elastic deformation of the oscillating member 40 is restored, the oscillating central shafts 46 are attracted to the semicircular wall portions at the back of the bearing recesses 26 and do not come off, the pair of oscillating central shafts 46 are rotatably housed in the pair of bearing recesses 26, and the spring portions 44 of the oscillating member 40 are housed in the housing spaces 22 of the connecting portions 18 of the main body 16. At this time, the pair of closing portions 42 are in a state where they respectively protrude obliquely outward into the pair of openings 28.

[0037] Next, the tip end 42d of each closing portion 42 is elastically deformed in the thickness direction to get over the engaging claws 30 of the main body 16, and then the curved portion 44b of the spring portion 44 is elastically deformed to reduce the angle, and inserted into the inner surface 30b of the engaging claws 30. When the force causing the elastic deformation is released, the elastic force of the spring portion 44 causes the tip end 42d to be inserted between the pair of engaging claws 30 at the tip end 12b of the first hook portion 12, and the abutting portion 50 is urged against the inner surface 30b of the engaging claws 30 to abut and engage.

[0038] At this time, the locking recesses 48 are positioned on the protrusions 36 of the pair of engaging claws 30, so the engaging claws are positioned in the thickness direction. Furthermore, the abutting portions 50 are biased against the inner surfaces 30b of the engaging claws 30 and are positioned without shifting in the left-right direction in FIG. 2(b), which intersects the thickness direction. Therefore, the tip 42d of the first hook portion 12 does not shift to the right, and the tip 42d of the second hook portion 14 does not shift to the left. Furthermore, the hook portions 52a of the engaged portions 52 are positioned in the hook portion accommodating recesses 38 of the protrusions 36 of the engaging claws 30, so the engaging claws are positioned without shifting in the left-right direction in FIG. 2(b), which intersects the thickness direction. Therefore, the tip 42d of the first hook portion 12 does not shift to the left, and the tip 42d of the second hook portion 14 does not shift to the right. Furthermore, the pivot shaft 46 is accommodated in the bearing recess 26 and does not move in the up-down direction in FIG. 2(b), which intersects the thickness direction.

[0039] As a result, the swinging member 40 is in a state where the closing portions 42 are positioned and closed in the pair of openings 28 on the main body 16, and assembly is completed. A force is applied to each closing portion 42 to rotate the tip end 42d side around the axis of the swing central shaft 46 due to the resilience that tries to increase the angle of the curved portion 44b of the spring portion 44, and the tip end 42d is pressed against the inner surface 30b of the engaging claw 30, preventing it from coming off.

[0040] Alternatively, the assembly method may be reversed, that is, inserting the tip 42d of one closing portion 42 of the swinging member 40 into the accommodation space 22 from the side edge 18c of the connecting portion 18 and taking it out from the side edge 18a.

[0041] Next, we will explain how to use the carabiner 10. To hang an object from the first hook portion 12 or the second hook portion 14, as shown in FIG. 6 , the closure portion 42 is pushed toward the inside of the opening 28, elastically deforming the spring portion 44 and rotating around the pivot axis 46, thereby separating the tip portion 42d from the engaging claw 30 of the first hook portion 12 and opening the opening. The hook portion 52a of the tip portion 42d engages with the hook portion accommodating recess 38 of the engaging claw 30 and is positioned to the left. However, because the engagement area is usually small, it can be opened by applying a certain amount of force. Then, after the object has passed through and the force is released, the resilient force of the spring portion 44 causes the closure portion 42 to rotate around the pivot axis 46 again, closing the opening 28. Because the closure portion 42 is always biased toward the engaging claw 30, it will not open unintentionally. Furthermore, the locking recess 48, abutment portion 50, locked portion 52, and hook portion 52a of the closing portion 42 are accommodated in the accommodating portion 34, accommodating portion 32, and hook portion accommodating recess 38 of the main body 16, and are locked in both the thickness direction and the direction intersecting the thickness direction, and will not come loose.

[0042] Furthermore, when one of the closing parts 42 is pushed in to open the opening 28, the curved part 44b bends and bulges slightly outward from the side edge 18b of the connection part 18 as shown in Figure 6, and a pulling force is generated on the straight part 44a of the spring part 44 to pull it outward. However, a force is applied to the opposite closing part 42 in the direction of closing the opening 28 around the swing center axis 46, so the opposite closing part 42 will not open inadvertently.

[0043] When a strong force is applied to an item hung on the first hook portion 12, the tip portion 12b of the first hook portion 12 elastically deforms slightly in a direction away from the tip portion 42d of the closure portion 42, but because the hook portion 52a is inserted deeper into the hook portion accommodating recess 38, the engagement area between the hook portion 52a and the hook portion accommodating recess 38 becomes larger, making it impossible to open, and therefore the engagement will not be released accidentally, ensuring safety.

[0044] The carabiner 10 of this embodiment is comprised of two components, the main body 16 and the swinging member 40. This simplifies the component configuration, reduces costs, facilitates parts management, and facilitates assembly of the main body 16 and the swinging member 40. The spring portion 44 and swinging center shaft 46 of the swinging member 40 are housed in the housing space 22 of the connecting portion 18 and are hidden from the surface of the connecting portion 18, resulting in a good appearance. The surface of the connecting portion 18 has a large area, allowing for the inscription of text and patterns, product names and manufacturers, and the addition of customer logos, thereby enhancing added value in terms of design and functionality. Furthermore, the absence of assembly holes allows for a simple, even exterior design, resulting in a high level of design and reduced risk of snagging on other components.

[0045] Furthermore, it can reliably hang an article and prevent accidental opening. The tip 42d of the closure part 42 is engaged in two directions with the engaging claws 30 of the main body 16. Even if the first hook part 12 or the second hook part 14 is deformed due to a heavy article or strong force being applied, the engagement area between the hook part 52a and the hook part accommodating recess 38 becomes large, making opening impossible and safe. The swing center shaft 46 is located at a predetermined distance toward the inner surface 42b of the closure part 42 from an extension of the center line between the inner surface 42b and the outer surface 42c. Therefore, even if the closure part 42 is rotated around the swing center shaft 46 to open one opening 28, the other opening 28 will not open and the biasing force will not weaken. The closure portion 42 has a swing center shaft 46 at its base end 42a and a contact portion 50 and a locked portion 52 at its tip end 42d, ensuring secure engagement with the main body 16 and high strength. This eliminates the need to provide rigidity to the first hook portion 12 and the second hook portion 14, allowing for greater design flexibility. The swing member 40 has two axes, the two swing center shafts 46, and a spring portion 44 with a curved portion 44b. When one closure portion 42 is pushed into the opening 28 to open it, a force is applied to the opposite closure portion 42 in the opening direction, causing it to be pressed against the engaging claw 30 of the first hook portion 12 or the second hook portion 14 and close. This prevents the opposite closure portion 42 from opening accidentally.

[0046] The main body 16 is easy to assemble because the pair of openings 28 are open and the accommodation space 22 is connected between the pair of openings 28. Furthermore, the bearing recess 26 is connected to the outside of the main body 16, so when assembling the oscillating member 40 to the main body 16, the curved portion 44b of the spring portion 44 is elastically deformed to widen the angle, and the oscillating central shaft 46 is inserted into the bearing recess 26 from outside the side edge portions 18a and 18b of the connecting portion 18, making assembly easy. Furthermore, because the oscillating central shaft 46 is not exposed to the outside of the main body 16, the design is improved.

[0047] The swinging member 40 is housed within the thickness of the main body 16, so it will not get caught on other objects, and the closing portion 42 is unlikely to come off the opening 28. The structure of the spring portion 44 is simple and less susceptible to creep. If a springy resin is used for the swinging member 40, the material of the main body 16 can be freely selected, and materials without springiness can be used, such as metal or recycled materials. Depending on customer requests, it can be used to propose sustainable products using metal for increased strength or recycled materials.

[0048] The carabiner of this invention is not limited to the above-described embodiment, and the shapes of the main body and the swinging member can be changed as needed, as long as the swinging member can be securely attached to the main body, and the number of hook portions on the main body can be one. It can be used to hang a variety of items, including cameras, whistles, bags, and cases. The materials, colors, surface treatments, transparency, etc. of the main body and the swinging member can be freely changed and can be modified as needed to suit the design and required functions. They may also be made of metal. [Explanation of symbols]
