Abstract
Description
Technical Field
[0001] The present disclosure relates to hooks used in various places in household goods, industrial goods, sports and leisure goods, and office supplies.
Background Art
[0002] Conventionally, spring hooks typified by carabiners have been used as hooks for daily life, outdoor activities, and sports. Many inventions have been made so that hooks with a carabiner structure can be used more easily, more quickly, or more safely for the purpose of hanging nearby objects.
[0003] For example, in Patent Document 1, the return link spring housed in the lever rod has a sliding contact end at the other end that slides on a spring receiving surface that is a curved concave surface, making the included angle outside the groove formed by the sliding contact end and the spring receiving surface an obtuse angle, so that the return link spring is less likely to fall out of the locking groove. As a result, it is a carabiner with a wide passing width of the insertion member that allows the lever part to rotate up to about 90 degrees, which is easy to use.

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, although the invention of Document 1 can widen the opening part, the difficulties associated with the use of conventional carabiners still remain regarding removal. For example, it is difficult to remove with one hand, and even when using both hands, when the lever rod of the hook is tilted inward, the hanging rod may get caught, the finger pressing the lever rod may interfere with the removal of the hanging rod, or the finger may be pinched between the lever rod and the carabiner body.
[0006] The present disclosure aims to provide a hook that can be smoothly attached and detached.
Means for Solving the Problem
[0007] The slide attachment / detachment hook of the present disclosure has a hook body having a hook base portion and a hook key portion that is bent and continuous from the hook base portion, and an opening / closing lever having one end connected via a rotation center portion provided on the hook base portion, and in the hook in which the opening / closing lever is rotationally biased in the direction of a contact point set on the hook key portion, the opening / closing lever having a bent portion rotates while intersecting the opening / closing lever extension portion after the bent portion and the hook base portion.
Effect of the Invention
[0008] According to the slide attachment / detachment hook of the present disclosure, when attaching and detaching the hook, smooth attachment and detachment can be achieved with one touch.

Mode for Carrying Out the Invention
[0010] Hereinafter, embodiments of the slide attachment / detachment hook of the present disclosure will be described with reference to the drawings.
[0011] Figure 1 shows the Based on perspective view of hook 1. Reference Hook 1 consists of a hook body 2 and an opening / closing lever 5. The hook body 2 is composed of a hook base 3 and a hook key part 4 that is bent and continuous from the hook base 3. In the drawings of the following embodiments, the descriptions of the hook body 2, the hook base 3, and the hook key part 4 are omitted to avoid complexity, but the configurations of the hook bodies are the same.
[0012] One end of the opening / closing lever 5 is connected to the hook base 3 at the rotation center part 8. The rotation center part 8 serves as the rotation center of the entire opening / closing lever 5. Also, near the center from the rotation center part 8 to the tip part 54 of the opening / closing lever 5, the opening / closing lever 5 is bent. In the state where the opening / closing lever 5 is closed, the contour of the bent part 53 contacts the inner circumference of the hook key part 4 at the contact point 6. The part from the rotation center part 8 of the opening / closing lever 5 to the contact point 6 is called the opening / closing lever base part 51, and the part from the contact point 6 to the tip part 54 of the opening / closing lever 5 is called the opening / closing lever extension part 52. The opening / closing lever 5 is biased to rotate in the closing direction by a leaf spring 71 installed at the rotation center part 8.
[0013] The way the bent part 53 of the opening / closing lever 5 contacts the contact point 6 of the hook key part 4 does not necessarily have to be point contact. It may be surface contact, or it may be a fitting-type contact form that fixes the position of the opening / closing lever 5 when it is closed.
[0014] A slit 9 is installed in the hook base 3 so that the opening / closing lever extension part 52 can pass through. The opening / closing lever extension part 52 passes through the slit 9 and protrudes outside the hook base 3. The slit 9 gives the opening / closing lever 5 that intersects the hook base 3 a free rotational movement and also serves as a rotation guide for the opening / closing lever 5.
[0015] The tip 54 of the opening / closing lever may always penetrate the slit 9 and protrude outside the hook 1. On the other hand, when the bent portion 53 is in contact with the contact point 6, if the tip 54 of the opening / closing lever is within the slit of the hook base, it has the effect that the protrusion of the extension of the opening / closing lever does not matter except during opening and closing.
[0016] If the opening / closing lever 5 has the above-described functions, it does not necessarily have to be square bar-shaped or round bar-shaped, and may be plate-shaped, lattice-shaped, or composed of a plurality of wire lines, or a combination thereof. A material that is difficult to deform is desirable.
[0017] The spring 7 attached near the rotation center portion 8 and biasing the opening / closing lever 5 in the closing direction is not limited to a leaf spring, and may be a coil spring, a torsion spring, a wire spring, or a shape memory alloy spring, etc.
[0018] In FIG. 1, a slit is made in the hook base 3 to allow the extension 52 of the opening / closing lever to pass through. However, a space corresponding to the slit may be provided in the extension of the opening / closing lever, and the hook base 3 may be passed through it so as not to restrict the movement of the rotation lever during opening and closing.
[0019] A string through-hole 20 for hanging a strap or a rope is provided in the head of the hook base 3. In the head of the hook base 3, not limited to the string through-hole 20 as shown in FIG. 1, something that assists the use of the hook body, or a function or decoration different from the use of the hook body may be attached. Or, nothing may be attached. In other words, it may be changed to be easy to use according to the use of the hook 1 or the preference of the user.
[0020] FIG. 2 is of the present disclosure Reference of the hook based onThis is a plan view, explaining how the hook is used. In the following description, the example of the object to which the hook is attached is the rod-shaped hanging rod 10, and a cross-sectional view of the hanging rod 10 is inserted in the figure. Fig. 2(a) shows the state when the hook 1 is attached to the hanging rod 10 or when the hook 1 is detached from the hanging rod 10. Fig. 2(b) shows the state when the hanging rod 10 passes by pushing aside the opening / closing lever 5. Fig. 2(c) shows the state when the hook 1 is attached to the hanging rod 10 or when trying to remove the hook 1 from the hanging rod 10.
[0021] When attaching the hook 1 to the hanging rod 10, move the hook 1 while sliding it so that the hanging rod 10 moves relatively in the direction of the arrow in Fig. 2(a). By doing so, the relative positions of the hook 1 and the hanging rod 10 change in the order of Fig. 2(a), Fig. 2(b), and Fig. 2(c), and the hook 1 is attached to the hanging rod 10. First, the opening / closing lever base 51 of the opening / closing lever 5 that was in contact with the contact point 6 receives the pressure from the hanging rod 10, the opening / closing lever 5 starts to rotate, and moves away from the contact point 6. Eventually, as shown in Fig. 2(b), the distance between the contact point 6 and the opening / closing lever 5 becomes the distance through which the hanging rod 10 can pass through, and the hanging rod 10 enters into the hook 1. When the hanging rod 10 passes through the bent portion 53, the opening / closing lever 5 rotates back by the force of the spring 7 until it contacts the contact point 6 in the closing direction in the opposite direction, and reaches the state shown in Fig. 2(c).
[0022] Conversely, when removing the hook 1 from the hanging rod 10, move the hook 1 while sliding it so that the hanging rod 10 moves relatively in the direction of the arrow in Fig. 2(c). By doing so, the relative positions of the hook 1 and the hanging rod 10 change in the order of Fig. 2(c), Fig. 2(b), and Fig. 2(a), and the hook 1 is detached from the hanging rod 10. First, the opening / closing lever extension 52 of the opening / closing lever 5 that was in contact with the contact point 6 receives the pressure from the hanging rod 10, the entire opening / closing lever 5 starts to rotate, and the opening / closing lever 5 moves away from the contact point 6. Eventually, as shown in Fig. 2(b), the space between the contact point 6 and the opening / closing lever 5 becomes the distance through which the hanging rod 10 can pass through, and the hanging rod 10 passes through the bent portion 53. After the hanging rod 10 passes through the bent portion 53, the opening / closing lever 5 rotates back by the force of the spring 7 until it contacts the contact point 6 in the closing direction, and reaches the state shown in Fig. 2(a).
[0023] As described above, by simply sliding the hook 1 in one direction without pressing and spreading the opening / closing lever 5 with a finger, the hook 1 can be easily and quickly hooked or removed. Since the opening / closing lever 5 only slides in a specific direction, it has the effect that it can be easily and quickly attached and detached even with one hand.
[0024] Figure 3 is a plan view of the embodiment of the present disclosure and is a plan view showing the specification requirements of the opening / closing lever 5. In this embodiment, the opening / closing lever extension 52 is curved. By curving it, the storage range of the hanging rod 10 in the hook key portion is widened, and a hanging rod 10 with a large diameter can also be hung. 1 However, depending on the state of the curvature, the opening / closing lever 5 may not move even when trying to slide the hook 1 to remove it.
[0025] The chain line A is a radius line passing through the rotation center portion and an arbitrary point 41 on the outer peripheral line of the contour of the opening / closing lever extension 52. The chain line B is a tangent line to the outer peripheral line at the aforementioned arbitrary point 41. Among the angles formed by the radius line A and the tangent line B, if the angle facing the hook base side is defined as the tangent angle β, when the tangent angle β is 90 degrees or less, the opening / closing lever 5 does not move even when trying to slide the hook 1 to remove it. It has been found that when the opening / closing lever extension 52 receives a pressing force in the removal direction by the hanging rod 10 and the tangent angle β is 90 degrees or less, a rotational moment in the closing direction opposite to the opening direction is generated in the opening / closing lever 5.
[0026] The tangent angle β may be approximately the same at any point on the outer side of the opening / closing lever extension 52, or may be changed for each location of the arbitrary point 41, but at any arbitrary point, it must be an angle of 90 degrees or more.
[0027]
[0028] Of The opening / closing lever extension 52 is shown in Figure 2 OfIf the hook is substantially straight, the bending angle α of the opening / closing lever of the bent portion 53 may be set to 90 degrees or more. This is because if the bending angle α is 90 degrees or more, the tangent angle β will be obtuse at any arbitrary point on the other part of the opening / closing lever extension 52, and the opening / closing lever 5 will open smoothly.
[0029] It has also been found that the force required to move the opening / closing lever 5 can be adjusted not only by the elastic force of the spring but also by changing the tangent angle β. In other words, if an opening / closing lever is prepared such that the tangent angle β is 90 degrees or more at any arbitrary point across the outer periphery of the opening / closing lever extension 52, when the tangent angle β is small, it becomes a hook that is difficult to remove, i.e., does not come off easily, and when the tangent angle β is large, it becomes a hook that is easy to remove, i.e., comes off easily.
[0030] In FIG. 3, a knob 30 is attached to the tip of the opening / closing lever 5. By pulling the knob 30, the opening / closing lever 5 can be opened. For example, in the case of a string that cannot apply sufficient pressure to the opening / closing lever 5 or a weak hanging rod 10, etc., the knob 30 can be pulled to open the opening / closing lever 5, and the string or the hanging rod 10 can be hung. The same applies when removing the string.
[0031] By appropriately shaping and attaching the knob, it is also possible to pull the knob with the finger of the same hand while holding the hook body of the present disclosure with one hand. Also, instead of the knob 30, the protruding portion of the opening / closing lever extension 52 from the hook body 2 may be lengthened to have the function of the above-described knob.
[0032] FIG. 4 is a plan view of the carabiner-type hook of the 2 embodiment of the present disclosure, and illustrates how the hook is used. In the carabiner-type hook, the end of the hook base 3 is curved in the direction of the end of the hook key portion 4 to form a rotation center portion 8, and is connected to the opening / closing lever 5. Although omitted in the figure, a spring that always acts in the direction of closing the opening / closing lever is installed at the rotation center portion 8.
[0033] The opening and closing lever 5 connected to the rotation center portion 8 is greatly curved toward the hook base 3 at the position of the contact point 6 at the tip of the hook key portion 4, passes through the slit 9 provided in the hook base 3, and has a structure that can rotate freely.
[0034] The hanging rod 10a indicates the position when the hook 1 is hung on the hanging rod 10 or when the hook 1 comes off the hanging rod 10. The hanging rod 10b represented by a dotted line indicates the position when the hanging rod 10 passes through the opening and closing lever 5 of the hook 1. The hanging rod 10c indicates the state when the hook 1 is hung on the hanging rod 10 or the position when trying to remove the hook 1 from the hanging rod 10. The actions and operations of the hanging rod, the hook body, and the opening and closing lever when attaching and detaching the hook to and from the hanging rod 10 are the same as those described in FIG. 2, so they are omitted.
[0035] In FIG. 4, the dashed line A is a radius line passing through the rotation center portion and an arbitrary point 41 on the outer side of the extension 52 of the opening and closing lever, and the dashed line B is a tangent line to the outer peripheral line of the extension 52 of the opening and closing lever at the aforementioned arbitrary point 41. Among the angles formed by the radius line A and the tangent line B, if the angle facing the hook base side is defined as the tangent angle β, when the tangent angle β is 90 degrees or more, smooth extraction is possible. Example 2 also operates on the same principle as in Example 1
[0036] The tangent angle β may be approximately the same at any point on the outer side of the extension 52 of the opening and closing lever, or may be changed for each location of the arbitrary point 41, but at any arbitrary point, it must be an obtuse angle.
[0037] Also, similar to the case of the embodiment 1 the force required to move the opening and closing lever 5 can be adjusted by changing the tangent angle β. In other words, if an opening and closing lever is prepared such that the tangent angle β is 90 degrees or more at any arbitrary point across the outer periphery of the extension of the opening and closing lever, when the tangent angle β is small, the hook is difficult to remove, that is, it is a hook that does not come off easily, and when the tangent angle β is large, the hook is easy to remove, that is, it is a hook that comes off easily.
[0038] FIG. 5 is a perspective view of the hook of the 3 first embodiment of the present disclosure. In FIG. 5, the opening / closing lever is constituted by a wire spring 73. A single wire spring is bent to form a wire spring having a pair of legs. The ends of the pair of legs are at staggered positions, and the tips are bent in a key shape to form bent terminals 74. The bent terminals 74 are inserted into and fixed to a pair of insertion holes 81 that form the rotation center of the hook base. The pair of insertion holes 81 are installed with a shift so that the hole axes do not overlap. When the hook is viewed in plan view, the pair of insertion holes are installed at positions shifted relatively close to each other.
[0039] In such a wire spring, since the two insertion holes 81 at the base of the wire spring serve as the center of rotation, there is no single rotation axis. The bent terminals 74 of the wire spring 73 are forcibly inserted into and installed in the fine holes arranged at shifted positions on both sides of the hook base 3. Thus, the elasticity of the wire spring 73 that attempts to eliminate the distortion becomes the force that closes the opening / closing lever 5. In the present disclosure, a rotation axis or a rotation center is called, including such rotation centers having a plurality of rotation centers at shifted positions and acting as if there is a single rotation axis.
[0040] Note that for the wire spring in FIG. 5, only the base of the opening / closing lever may use a wire spring, or the entire opening / closing lever may be made of a wire spring, and a reinforcing member that bridges a pair of legs may be attached to a bent portion or the like.
[0041] FIG. 6 is a perspective view of the 4 first embodiment of the present disclosure. A wire spring similar to that in FIG. 5 is used, but the extension 52 of the opening / closing lever is different. The extensions of the opening / closing lever 5 divided into two cross both sides of the hook base 4 and meet at the tip 54 of the opening / closing lever. By adopting such a structure, it has the effect that there is no hindrance to the rotation of the opening / closing lever when it is opened and closed. In such a form, the hook base serves as a rotation guide for the opening / closing lever.
[0042] As described above, the embodiments of the present disclosure have been described in detail. However, the present disclosure is not limited to the above-described embodiments, and various changes, improvements, etc. are possible without departing from the gist of the present disclosure. Needless to say, all or part of each of the above embodiments can be combined as appropriate within a non-contradictory range.
