[0008] The present invention will be described below.Unless otherwise specified, it should be understood that the terms used in this specification are used in the meanings generally used in the relevant field.Therefore, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the art to which this invention belongs.In the event of any discrepancy, this specification (including definitions) shall prevail.

[0009] In this specification, the term "about" refers to a range of ±10% of the following number.

[0010] The present invention addresses the problem of obtaining a hook that allows an object to be attached or detached from the hook with a simple operation, for example, a hook for suspending an object, comprising: a hook body having a base body and a hook portion for suspending the object; and a locking device whose base end is connected to the top of the base body and whose tip end abuts against the hook portion with a biasing force from the inside of the hook portion toward the hook portion, thereby preventing the object from coming off; and the above problem is solved by configuring the hook so that the position where the locking device and the hook portion abut and the lower end of the hook portion are arranged in a substantially perpendicular line.

[0011] The above problem is also solved by configuring a hook for hanging an object, comprising: a hook body having a base body and a hook portion for hanging the object; and a locking device whose base end is connected to the hook portion and whose tip end abuts against the base body with a biasing force from the hook portion side toward the base body, thereby preventing the object from coming off.

[0012] The above problem is also solved by configuring a hook for hanging an object, comprising: a base body; and a hook main body having a hook portion for hanging the object, wherein the base body and the hook portion respectively have a first protrusion and a second protrusion that protrude in opposite directions, and the first protrusion has a base end connected to the upper part of the base body, and a locking device whose tip end abuts against the hook portion with a biasing force from the inside of the hook portion toward the hook portion, thereby preventing the object from coming off.

[0013] Furthermore, the above problem is solved by configuring a hook for hanging an object, comprising: a hook body having a base body and a hook portion for hanging the object; and a locking device whose base end is connected to the upper part of the base body and whose tip end abuts against the hook portion with a biasing force from the outside of the hook portion toward the hook portion, thereby preventing the object from coming off.

[0014] The hook of the present invention basically comprises a hook body having a base body and a hook portion for hanging an object, and a fastener that applies a biasing force toward the inside or outside of the hook portion between the base body and the hook portion to prevent the object from being removed. The hook of the present invention can be attached to any object, such as a side wall or side of a refrigerator, shelf, bag, or backpack, or a strap or key chain.

[0015] (Base Body) The shape, size, thickness, material, etc. of the base body may be arbitrary. For example, the base body 10 is a metal plate, but the present invention is not limited to this. For example, the base body may be made of resin such as plastic, wood, ceramic, or a mixture of these materials.

[0016] The base body may have any external shape, such as a rectangle, a circle, an ellipse, or a combination thereof. The thickness and size of the base body may also be arbitrary, but it is preferable to keep the thickness small and the size as small as possible to reduce costs. The base body may also be provided with holes such as recesses or slits to reduce weight without compromising its strength. The hook may also be provided with holes for hanging on an object to which the hook is attached, or a hanging hardware for attaching to the object may be provided, and the hook may be attached using this. The base body may also be directly fixed to the object to which it is attached using adhesive or a fastener. Furthermore, an opening may be provided to expand the range of movement of the fastener.

[0017] (Hook portion) The hook portion has a curved portion that can hook an object (a hanging portion such as a string attached to the object), and its shape, size, thickness, material, etc. can be arbitrary. For example, the hook portion is made of metal, but the present invention is not limited to this. For example, it may be made of resin such as plastic, wood, ceramic, or a mixture of these materials. It may also be made of the same material as the base body, or it may be a separate body made of a different material. The base body and the hook portion may be integrated or separate.

[0018] The shape of the hook portion may be, for example, a hook shape, a substantially L-shape, or a substantially semicircular shape in cross section.

[0019] It is preferable that the abutment portion of the hook portion that abuts against the locking device and the lower end of the curved portion of the hook portion are arranged in a substantially perpendicular line. (Locking Device) The locking device is made of a metal wire or plate material and is configured to generate a biasing force. In one embodiment, the locking device is made by bending a wire material into a ring shape. Both ends of the wire material bent into a ring shape are base ends, and the position opposite the base ends is the tip end. The thickness and length of the wire material can be arbitrary.

[0020] When the base end of the locking device is connected to the hook body, a biasing force is generated so that the tip end abuts against the base body, and when the base end of the locking device is connected to the base body, a biasing force is generated so that the tip end abuts against the hook body.

[0021] The fastener is composed of a first arm member and a second arm member, and the boundary between the first and second arm members is a bending point, with the second arm member bending relative to the first arm member. The fastener may further include a third arm member bending relative to the second arm member at a bending point. Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0022] (Embodiment 1) Fig. 1 is a six-view diagram showing a hook 1 according to Embodiment 1 of the present invention. As shown in Fig. 1, the hook 1 includes a hook main body including a substantially rectangular, plate-like base body 10 and a hook portion 20 curved like a hook, and a locking device 30 having a base end E coupled (axially attached) to the top of the base body 10 and a tip end H that applies a biasing force from the inside of the hook portion 20 toward the hook portion 20 to prevent an object that abuts against the hook portion 20 at a contact point S from coming off. The base body 10 has a hole 11 at its top that is used to suspend the hook 1 from an object. The hole 11 that is used to suspend the hook 1 from an object may be provided at the top of the base body 10, or may be provided at the bottom or side.

[0023] The base body 10 also has a hole 12 in the center and / or bottom. By providing such a hole 12, it is possible to reduce the weight of the hook 1 and the manufacturing cost.

[0024] Although the object to which the hook 1 is attached is not shown in Figure 1, specifically, it is attached to the side of a school bag. Specifically, the fastener 30 is a single wire bent into a substantially rectangular ring, with both ends of the wire as base ends E connected to the top of the base body 10. The portion opposite base end E is a tip end H, and a first arm member 31 and a second arm member 32 are located between base end E and tip end H. The second arm member bends relative to the first arm member 31, with the boundary between the first arm member 31 and the second arm member 32 acting as a bending point, and the boundary abuts against the hook portion 20 at abutment point S. The first arm member 31 and the second arm member 32 are biased toward the hook portion 20 from the inside of the hook portion 20 (from the direction of the base body 10) by a biasing force, with the base end E connected to the base body 10 as an axis.

[0025] The bending point S between the first arm member 31 and the second arm member of the locking device 30 becomes the contact point where the hook portion 20 comes into contact, and the contact point and the lower end portion 21 of the curved portion of the hook portion 20 are configured to form an approximately perpendicular line.

[0026] The hook 1 of the first embodiment of the present invention has the above-described configuration, so that when suspending an object from the hook 1, the simple action of pulling the hanging portion of the object, such as a string, downward from above toward the abutment point between the hook portion 20 of the hook 1 and the locking device 30 overcomes the biasing force of the locking device 30 toward the hook portion 20, allowing the hanging portion of the object to pass through the abutment point S and be inserted into the hook body, thereby making it possible to attach the object to the hook 1. When the object is attached to the hook 1, the hanging portion is positioned at the lower end 21 of the curved hook portion 20.

[0027] Specifically, fastener 30 is formed by bending a single wire into a substantially rectangular ring, and both ends (base end E) of the wire are joined to the upper part of base body 10. A first arm member 31 and a second arm member 32 are provided between base end E and tip end H, and second arm member 32 extends from hook portion 20 toward base body 10, with the boundary between first arm member 31 and second arm member 32 serving as bending point S. Bend point S is configured to abut against hook portion 20 as a contact point.

[0028] The locking device 30 has a base end E connected to the top of the base body 10 as an axis, and the first arm member 31 and the second arm member 32 are biased from the base body 10 side toward the hook portion 20 side by a biasing force.

[0029] When attaching or detaching an object from hook 1, the hanging portion of the object, which is located at lower end 21 of hook portion 20, is pulled upward. In this case, since inflection point S of locking device 30 is located on a line approximately perpendicular to lower end 21 of hook portion 20 as a contact point that abuts against hook portion 20, when the hanging portion of the object is pulled upward, it can easily come into contact with the contact point, and the biasing force of locking device 30 can easily release the state of abutment against hook portion 20. Therefore, the hook in embodiment 1 of the present invention achieves an excellent effect that could not be achieved with conventional hooks, in that an object can be attached or detached from hook 1 by the simple action of pulling the hanging portion of the object upward.

[0030] In particular, by providing the hook 1 of the present invention on the side of the school bag, a child can easily attach and detach an object to and from the hook 1 with the simple operation of pulling down and / or pulling up the hanging part of the object suspended from the hook 1, even while the school bag is still on their back. Furthermore, with conventional snap hooks, when removing an object, it is necessary to press a lever to release the hanging part of the object, but this action is difficult for children in the lower grades of elementary school and makes them hard to use. However, the hook 1 of the present invention does not require such an operation, and has the excellent effect of being easy to use.

[0031] Note that the first arm member 31 and the second arm member 32 are inclined from the hook portion 20 side toward the base body 10 side at the boundary (bending point S) between them toward their tip ends. With this configuration, when the hanging portion of the object is pulled up from the lower end 21 of the hook portion 20, the hanging portion of the object can be more easily guided along the second arm member to the abutment point between the hook portion 20 and the locking device 30, making it possible to easily attach and detach the object from the hook 1. Therefore, in a configuration having the first arm member 31 and the second arm member 32, even if the lower end 21 of the hook portion 20 and the abutment point with the hook portion 20, which is the abutment point between the first arm member and the second arm member of the locking device 30, are not positioned on a substantially vertical line, the hanging portion of the object can be detached from the hook 1 by the simple operation of pulling the hanging portion of the object upward from the lower end 21 of the hook portion 20. In addition, the configuration having the first arm member 31 and the second arm member 32 and the configuration in which the lower end 21 of the hook portion 20 and the contact points between the locking device 30 and the hook portion 20 are arranged on an approximately vertical line may be provided with one of each, or both.

[0032] The hook portion 20 also has a restricting portion 22. The provision of this restricting portion 22 has the effect of preventing the second arm member 32 from moving unexpectedly.

[0033] (Embodiment 2) Fig. 2 is a six-view diagram showing a hook 1 according to Embodiment 2 of the present invention. As shown in Fig. 2, the hook 1 includes a hook main body including a substantially rectangular, plate-like base body 10 and a hook portion 20 curved like a hook, and a locking device 30 having a base end E connected to the lower part of the hook portion 20 and a tip end H that prevents an object abutting the base body 10 at a contact point S from coming off by applying a biasing force from the inside of the hook portion 20 toward the base body 10. The hook 1 according to Embodiment 2 differs from the hook 1 according to Embodiment 1 in that the base end E of the locking device 30 according to the hook 1 according to Embodiment 1 is connected to the upper part of the base body 10 and the tip end is biased toward the hook portion 20, whereas the base end E of the locking device 30 according to the hook 1 according to Embodiment 2 is connected to the lower part of the hook portion 20 and the tip end is biased toward the base body 10. The other configurations are the same.

[0034] Specifically, the fastener 30 is formed by bending a single wire into a substantially rectangular ring, with both ends of the wire joined to the lower part of the hook portion 20. A first arm member 31 and a second arm member 32 are provided between the base end E and the tip end H, and the boundary between the first arm member 31 and the second arm member 32 forms a bending point S, with the second arm member 32 extending from the base body 10 side toward the hook portion 20 side. The bending point S is configured to abut against the base body 10 as a contact point.

[0035] The locking device 30 has a base end E connected to the hook portion 20 as an axis, and the first arm member 31 and the second arm member 32 are biased from the hook portion 20 toward the base body 10 by a biasing force.

[0036] The contact point S where the locking device 30 contacts the hook portion 20 and the lower end portion 21 of the curved portion of the hook portion 20 are configured to be substantially perpendicular to each other.

[0037] The hook 1 of the second embodiment of the present invention has the above-described configuration, so that when suspending an object from the hook 1, the simple action of pulling the hanging portion of the object, such as a string, downward from above toward the abutment point between the hook portion 20 of the hook 1 and the locking device 30 overcomes the biasing force of the locking device 30 toward the hook portion 20, allowing the hanging portion of the object to pass through the abutment point and be inserted into the hook body, thereby attaching the object to the hook 1. When the object is attached to the hook 1, the hanging portion is positioned at the lower end 21 of the curved hook portion 20.

[0038] When attaching or detaching an object from hook 1, the hanging portion of the object, which is located at lower end 21 of hook portion 20, is pulled upward. In this case, since inflection point S of locking device 30 is located on a line approximately perpendicular to lower end 21 of hook portion 20 as a contact point where the hanging portion of the object abuts against hook portion 20, when the hanging portion of the object is pulled upward, it can easily come into contact with the contact point, and the biasing force of locking device 30 can easily release the state of abutment against hook portion 20. Therefore, the hook in embodiment 2 of the present invention achieves an excellent effect that could not be achieved with conventional hooks, in that an object can be attached or detached from hook 1 by the simple action of pulling the hanging portion of the object upward.

[0039] In particular, by providing the hook 1 of the present invention on the side of the school bag, an excellent effect can be obtained in that an object can be easily attached to or detached from the hook 1 by simply pulling down and / or pulling up the hanging part of the object hung from the hook 1, even while the child is still wearing the school bag on his / her back.

[0040] The second arm member 32 is inclined from the bending point S to the tip end, from the base body 10 side toward the hook portion 20 side. With this configuration, when the hanging portion of the object is pulled down from above toward the abutment point between the hook portion 20 of the hook 1 and the locking device 30, the hanging portion of the object is guided along the first arm member to the bending point S (abutment point), making it easier to attach the object to the hook 1.

[0041] In addition, the base body 10 has a protruding portion 14 at the bottom that faces the hook portion 20. The protruding portion 14 prevents an object from reaching the contact point between the hook portion 20 and the locking device 30 when the object is pushed upward by an unexpected force, thereby preventing the object from being accidentally detached.

[0042] 3 is a six-view diagram showing a hook according to a modification of the second embodiment of the present invention. As can be seen from FIG. 3, the base body 10 has a bottle opener-like or substantially T-shaped shape. By adopting such a shape, it is possible to further reduce the weight and manufacturing costs.

[0043] When attaching or detaching an object from hook 1, the hanging portion of the object, which is located at lower end 21 of hook portion 20, is pulled upward. In this case, since inflection point S of locking device 30 is located on a line approximately perpendicular to lower end 21 of hook portion 20 as a contact point where the hanging portion of the object abuts against hook portion 20, when the hanging portion of the object is pulled upward, it can easily come into contact with the contact point, and the biasing force of locking device 30 can easily release the state of abutment against hook portion 20. Therefore, the hook in embodiment 2 of the present invention achieves an excellent effect that could not be achieved with conventional hooks, in that an object can be attached or detached from hook 1 by the simple action of pulling the hanging portion of the object upward.

[0044] In particular, by providing the hook 1 of the present invention on the side of the school bag, an excellent effect can be obtained in that an object can be easily attached to or detached from the hook 1 by simply pulling down and / or pulling up the hanging part of the object hung from the hook 1, even while the child is carrying the school bag on his or her back.

[0045] The first arm member 31 is inclined from the bending point S toward the base end E, from the base body 10 toward the hook portion 20. With this configuration, when the hanging portion of the object is pulled down from above toward the abutment point between the hook portion 20 of the hook 1 and the locking device 30, the hanging portion of the object is guided along the first arm member to the bending point S (abutment point), making it easier to attach the object to the hook 1.

[0046] (Embodiment 3) Figure 4 is a six-view diagram showing a hook 1 according to a third embodiment of the present invention. As shown in Figure 4, the hook 1 has a hook body consisting of a substantially rectangular, plate-like base body 10 and a hook portion 20 that is curved like a hook. The base body 10 has a first protrusion 15 facing toward the hook portion 20, and the hook portion 20 has a second protrusion facing toward the base body 10. The distance between the first protrusion 15 and the second protrusion 25 is narrower than the distance between the hanging portion of the object. With this configuration, when hanging an object on the hook 1, by strongly pulling the hanging portion of the object toward the gap between the first protrusion 15 and the second protrusion 25, the hanging portion of the object slips through the gap between the first protrusion 15 and the second protrusion 25 and is inserted, thereby making it possible to easily hang and attach the object to the hook 1.

[0047] Furthermore, since the first protrusion 15 and / or the second protrusion 25 have an approximately conical shape with a diameter that gradually decreases in the direction of protrusion, when the hanging portion of the object is pulled down and / or pulled up into the gap between the first protrusion 15 and the second protrusion 25, the hanging portion of the object is guided toward the gap between the first protrusion 15 and the second protrusion 25, making it easier to attach and / or detach the object to the hook 1.

[0048] Furthermore, the position between first protrusion 15 and second protrusion 25 and lower end 21 of hook portion 20 may be configured to be positioned on a substantially vertical line. With this configuration, simply pulling the hanging portion of the object up vertically allows the hanging portion of the object to pass through the position between first protrusion 15 and second protrusion 25, making it possible to attach and detach the object from hook 1 with a simple operation, an excellent effect that could not be achieved with conventional hooks.

[0049] (Embodiment 4) Fig. 5 is a six-view diagram showing a hook 1 according to a fourth embodiment of the present invention. As shown in Fig. 5, the hook 1 includes a hook main body including a substantially rectangular, plate-like base body 10 and a hook portion 20 curved like a hook, and a locking device 30 having a base end E connected to the top of the base body 10 and a tip end H that applies a biasing force from the outside of the hook portion 20 toward the hook portion 20 to prevent an object from coming into contact with the hook portion 20 at a contact point S. The base body 10 has a hole 11 at its top that is used to suspend the hook 1 from an object. The hole 11 that is used to suspend the hook 1 from an object may be provided at the top of the base body 10, or may be provided at the bottom or side.

[0050] The base body 10 also has a hole 12 in the center and / or bottom. By providing such a hole 12, it is possible to reduce the weight of the hook 1 and the manufacturing cost.

[0051] Although the object to which the hook 1 is attached is not shown in Figure 5, it is specifically attached to the side of a school bag. Specifically, the fastener 30 is a single wire bent into a substantially rectangular ring, with both ends of the wire attached to the upper part of the base body 10 as base ends E (axial attachment). A first arm member 31 and a second arm member 32 are located between the base end E and the tip end H. The boundary between the first arm member 31 and the second arm member 32 forms a bending point S, and the second arm member 32 gradually extends outward from the hook portion 20 toward its tip end. The bending point S is configured as the point of contact with the hook portion 20. The first arm member 31 and the second arm member 32 are biased toward the hook portion 20 from the outside of the hook portion 20 by a biasing force, with the base end E connected to the base body 10 as the axis.

[0052] The hook 1 of the fourth embodiment of the present invention has the above-described configuration, so that when hanging an object on the hook 1, the object is attached to the hook 1 by pulling up the hanging portion of the object from below at the point where the hook portion 20 abuts while the locking device 30 is biased toward the hook portion 20 from the outside, in contrast to the operation of pulling down the hanging portion of the object when attaching an object to a conventional hook. With this configuration, the task of manually pushing back the hook portion, which is required with conventional hooks, is no longer necessary, and operability can be improved.

[0053] The hook portion 20 is provided with a recess or protrusion 24 into which a portion of the fastener 30 (the contact point S that contacts the hook portion 20) fits. The provision of the recess or protrusion 24 allows the fastener 30 to be more reliably biased and abut against the hook portion 20, making it possible to more firmly attach an object to the hook 1. Furthermore, because the fastener 30 is biased toward the hook portion 20 from the outside of the hook portion 20, when attaching or detaching an object from the hook 1, it is possible to detach the hanging portion of the object from the hook 1 simply by pulling the hanging portion of the object down from the hook body, thereby overcoming the bias of the fastener 30 toward the hook portion 20.

[0054] Furthermore, tip 26 of hook portion 20 (the end opposite the end that connects to base body 10) has a bent portion that is bent toward base body 10 relative to the point where hook portion 20 contacts locking device 30. By providing tip 26 with a bent portion, a space is created to guide the hanging portion of the object, and the hanging portion of the object remains in a position within the circle, and then by pulling downward, it becomes possible to easily detach the hanging portion of the object from the hook.
