Description

The present invention relates to an auxiliary tool that avoids direct contact with an object.

Ingenuity to prevent infection with the new coronavirus is being studied in various places. It is considered to be a droplet or contact infection rather than an airborne infection, so it is recommended to avoid contact with common objects with bare hands as much as possible. For example, a lifestyle device such as pressing an elevator button with a folding umbrella has been proposed.

However, it is not always possible to carry a bulky object such as a folding umbrella with you. Also, as a substitute for a hand, it may be necessary to grasp an object in addition to pressing a button or the like. Therefore, it has been proposed to use a hook of a portable size. As such hooks, a plurality of hooks having, for example, a portion for hooking a finger and a portion for a protruding hook formed by punching or carving out a metal plate have been proposed (for example, Non-Patent Documents 1 and 2). ).

However, although the hook carved from the metal plate is lightweight and not bulky, it is not so thick as it is originally a plate. The place where the force is applied for fixing is not the palm but one finger, and the force is applied linearly from the first joint to the second joint on the inside of the finger. If you just push a button or lightly hook something, this is fine. However, problems can occur when used as a support for the body, such as handrails and straps of public transportation that many people come into contact with. For example, when trying to support the entire weight with a hook that hooks a handrail or a hanging strap during sudden braking, the pressure due to the total weight is concentrated on a thin linear portion of one finger.

Therefore, the present invention provides a contact avoidance device that is easy to carry, suppresses the possibility of injury even when weight is applied in an emergency, is excellent in safety and portability, and infectious diseases such as the new coronavirus. The purpose is to contribute to the prevention of the spread of.

This invention
The above-mentioned problem was solved by a hand-held hook having a spiral portion and a hook portion formed by an integral resin-coated wire.

By grasping the spiral portion formed by the resin-coated wire, the entire hook can be supported by a wide surface inside the palm or fingers. By forming the spiral portion and the hook portion with an integral resin-coated wire, it is possible to support a handrail or a hanging strap hooked on the hook portion with a force that firmly grips the spiral portion.

The hook portion is formed by rolling the farthest portion formed by folding back in a direction approaching the spiral portion side in the middle of a line extending in a direction away from the spiral portion (outward line) toward the spiral portion side. The form to be used can be adopted. According to this configuration, the hook portion is not the end portion of the resin-coated wire but the rounded portion in the middle of the wire, so that the edge does not appear even if the hook portion is touched. As a result, even if the user or an infant protected by the user touches or puts it in the mouth, the possibility of injury can be kept low.

Further, it is possible to adopt a form in which the other end of the resin-coated wire (return line) folded back from the farthest portion toward the spiral portion is folded into the spiral of the spiral portion. In this way, since the spiral portion and the hook portion are connected by two resin-coated wires (outward line and return line) that reciprocate, the load applied to the hook portion is distributed to the two resin-coated wires. As a result, the load capacity limit is improved, and even if a large force is applied to the spiral portion, the overall shape is less likely to be deformed. Further, since the other end is folded into the spiral portion, the edge is not exposed to the outside, and it is possible to prevent the end of the resin-coated wire from being caught by fibers or the like. At this time, it is desirable that one end of the resin-coated wire, which is the starting point of the spiral portion, is covered by the bent portion on the other end side of the resin-coated wire to be folded so as to be difficult to touch.

As the spiral portion, a form in which the axial direction of the spiral is arranged in a direction perpendicular to or substantially perpendicular to the forward line and the return line can be adopted. It is hard to slip even if the gripping force of the spiral part is weak, and it is easy to support the body even when you cannot afford to apply force due to sudden sudden braking when using it in the car.

The hand-held hook according to the present invention can avoid the situation where a finger touches a common object with a device having a minimum size. In addition, when standing on public transportation and supporting the body by hooking it on a strap or handrail, the force applied locally to the fingers is dispersed even if a load is suddenly applied. Hard to get injured. In addition, since the whole is a resin-coated wire and is covered with resin, even if it comes into contact with the human body, fibers or other articles, it is difficult to damage them, so there is a problem even if it is casually put in the bag when carrying around. It is unlikely to occur. This resin is easily colored by mixing pigments and the like, and various color variations can be easily realized. Even in situations where multiple hand-held hooks of the same shape are available at home or at work, it is possible to easily determine which hand-held hook is used by each individual based on the color variation, so if the color is different, another person used it. It is also possible to prevent the situation where the handheld hook is accidentally grasped.

In addition, since it can be hooked at a position beyond the gripped hand, it is now possible to reach the hanging straps that were too high for relatively short children and elderly people to reach with bare hands, and use public transportation. It is possible to improve the safety when doing so.

Unlike products made only of resin, metal wire is used as the core wire, so strength can be ensured. Further, even if the hook part is deformed and cannot be hooked, it can be easily restored to its original shape by bringing it into an environment where it can be repaired.

Hereinafter, the handheld hook according to the present invention will be described. The hand-held hook according to the present invention has a spiral portion and a hook portion formed by an integral resin-coated wire.

A first embodiment of the handheld hook 1 according to the present invention is shown in FIG. 1 (a) is a perspective view, FIG. 1 (b) is a plan view, FIG. 1 (c) is a front view, and FIG. 1 (d) is a right side view. In this embodiment, the entire hand-held hook 1 is formed by processing a single resin-coated wire.

The resin-coated wire has one or more resin layers around the metal wire to be the core wire. An adhesive layer or other layer may be provided between the resin layer and the metal wire. The adhesive layer adheres the metal wire and the resin layer.

The metal wire needs to have a certain strength, and it is desirable that the metal wire has a strength that cannot be easily bent by human power. As the material, a general iron-based material can be used, but a steel material may also be used.

Further, a plating layer for sacrificial corrosion protection may be provided around the metal wire. Corrosion resistance and durability are improved. Examples of the plating layer include zinc plating and zinc aluminum alloy plating.

The diameter of the core wire portion of the metal wire (including the plating layer when it has a plating layer) is not particularly limited, but it is 2.0 mm or more from the viewpoint of strength enough to maintain the shape as a hook. It is preferable that the thickness is 3.0 mm or more. If the diameter of the core wire is less than 2.0 mm, even if the circumference is covered with resin, it will be slightly weak in terms of strength, and it will be momentary when a sudden brake is applied when it is hooked on a hanging strap in the car. The possibility that the hook portion 12 will stretch and not return when a large load is applied cannot be ignored. On the other hand, if it is too thick, it will be heavy and bulky, making it inconvenient to carry and difficult to grip. In addition, the processing load during manufacturing becomes too large, making it difficult to manufacture. Therefore, the diameter of the core wire portion is preferably 7.0 mm or less, preferably 6.0 mm or less.

The adhesive layer is provided in order to prevent friction or twisting between the metal wire and the resin layer and to increase the durability against mechanical action. If the resin layer itself has a high affinity for the metal wire, it may not be provided. On the other hand, it is desirable to provide it when the metal wire and the resin layer are difficult to adhere to each other. As the adhesive to be used, a polyolefin-based adhesive is easy to use in many combinations, and a polyethylene-based adhesive is particularly preferable.

The above resin layer exerts a plurality of important effects as a hand-held hook. First, it prevents corrosion of the metal wire and prolongs the life of the hand-held hook as a product. Further, since the gripping portion (spiral portion 11) is covered with resin, there is little feeling of coldness when using it in winter and it is easy to grip. Further, since the hook portion 12 is covered with a resin that is softer than metal, it is not necessary to damage common objects such as handrails and hanging straps on which the hook portion 12 is hooked. Furthermore, even if the edge of the core wire is projected on one end (22) of the resin-coated wire, the periphery of the metal wire is covered with the resin, so that the fibers and the skin are less likely to be caught.

Examples of the material of such a resin layer include vinyl chloride resin, polyolefin resin, polyethylene resin, polypropylene resin, ionomer resin and the like. The material is not limited to the resin alone, and the resin may contain other additives and strengthening agents. For example, by heating and melting these resins and extrusion molding, the metal wire can be coated with the resin layer.

Further, the resin layer may contain a dye or a pigment for coloring as a component other than the resin. Since it can be easily colored by these, it is possible to prepare a hand-held hook with various color variations. For this reason, when the hand-held hooks used by many people are collected, it becomes easy to distinguish which one is their own hand-held hook by color. Moreover, not only a single color but also various patterns and designs can be applied.

The thickness of the resin layer is preferably 100 μm or more, preferably 300 μm or more, and particularly preferably about 500 μm for a single piece of meat. This is because if the thickness is less than 100 μm, the protective effect of the resin layer is insufficient, and the metal wire may be torn and exposed. On the other hand, it is not realistic to exceed 2000 μm, and it is preferable that it is 1000 μm or less.

The surface of the resin layer may be further subjected to antibacterial treatment such as metal ions or other hygienic treatment. Further, a substance having an antibacterial effect may be contained in the material of the resin layer. Further, it is preferable that the surface of the material is not deteriorated by ethyl alcohol so that it can be sterilized and disinfected with ethyl alcohol after use.

The strength of the resin-coated wire itself including the resin layer ^{is preferably 300 N / mm 2} or more, and more preferably 400 N / mm ² or more. If the strength is too low, it may be deformed during use, making it useless as a hook. There is no particular problem as a product due to the high strength, but the load required for processing into the shape of the hand-held hook according to the present invention becomes too large, so that ^{it is preferably 2000 N / mm 2} or less, and 1500 N / mm. It is more preferably mm ^{2 or less.}

Next, the shape of the handheld hook 1 according to the present invention will be described. As shown in FIG. 1A, it has a spiral portion 11 and a hook portion 12, and the outbound line 24 and the return line 28 are connected between them.

The spiral portion 11 is formed by winding a resin-coated wire (21) so as to form a spiral while maintaining a diameter. One end 22 of the resin-coated wire 21 is one end of the spiral portion 11. The area up to the other end 23 of the spiral portion 11 is a place where a finger should be hooked during use.

It is preferable that the resin-coated wires 21 adjacent to the spiral portion 11 in the axial direction of the spiral are as close as possible to each other. This is because if the distance between the individual resin-coated wires 21 is too large, the flesh of the fingers may be pinched if the individual resin-coated wires 21 contract in the axial direction like a spring while being gripped. Further, if the space is too large, there is a possibility that a finger may get caught between the resin-coated wires 21 even if the user holds the resin as it is. Therefore, the distance between the resin-coated wires 21 is preferably 2 mm or less, more preferably 1 mm or less, and particularly preferably in close contact with each other.

The diameter of the spiral of the spiral portion 11 is preferably 1 cm or more, preferably 1.5 cm or more. If the spiral is too thin, it will be easily deformed when the finger is hooked, and it will not be possible to exert sufficient strength. On the other hand, if it exceeds 8 cm, it is too thick and difficult to grip, so 8 cm or less is preferable, and 5 cm or less is more preferable because it is easy for most people to use.

The axial length of the spiral portion 11 is preferably 2.5 cm or more, and preferably 5 cm or more. If you can't hook at least one finger, you can't hold the whole thing. In order to support the body in a stable manner, it is preferable to be able to hook two or more fingers. It is especially preferable to hook four fingers. However, the width is too wide and bulky when carried, so it is preferably 10 cm or less.

The forward line 24 and the return line 28 extend in a direction substantially perpendicular to the axis of the spiral portion 11. The outward line 24 extends from the other end 23 of the spiral portion 11 as it is with the resin-coated wire 21. On the other hand, in the double track 28, a resin-coated wire inserted into the spiral is extended from one end 22 side of the spiral portion 11.

At the tip of the forward line 24 and the return line 28, as shown in FIG. 1D, the round curved portion 25, which is rounded and bent so that the cross-sectional shape of the spiral portion 11 is substantially semicircular when viewed from the axial direction, 27 is formed. The farthest portion 26 between the rounded portions is the portion farthest in length along the line from the end portions (22, 23) of the spiral portion 11. The portion from the round curved portion 25 to the round curved portion 27 sandwiching the farthest portion 26 becomes a hook-shaped portion to form the hook portion 12. The radius of curvature r of the round curved portions 25, 27 when viewed from the axial direction of the spiral portion 11 is preferably 5 mm or more. If it is too small, it will be difficult to hold the straps and handrails. On the other hand, if it is too large, it will be bulky, so it is preferably 30 mm or less.

A method of forming this hand-held hook will be described with reference to FIG. First, a part of one resin-coated wire is spirally connected to form a spiral portion 11. One end 22 is the starting point of the spiral. Here, if one end 22 is located in the direction in which the farthest portion 26 is to be formed in the circumferential direction of the spiral, the one end 22 is a bent portion described later in the finally completed form. It is preferable because it is guarded by 29 and is less likely to get caught in fibers or skin. The other end 23 extends from the end point of the spiral in a direction substantially perpendicular to the axis of the spiral. This is the outbound line 24. The folded portion 31 is formed by bending in the middle of the outward line 24 to form the farthest portion 26 farthest from the spiral portion 11, and further forms the folded portion 32 folded in the direction closer to the spiral portion 11 side. To do. The line approaching the spiral portion 11 side is the double track 28. The return line 28 is bent so as to be substantially parallel to the inner side in the axial direction of the spiral portion 11 at a position where it can contact one end portion 22 of the spiral portion 11 to form the bent portion 29. The length is such that the other end 30 of the resin-coated wire terminates in the middle of the spiral portion 11. As described above, the form shown in FIG. 2A is obtained.

Then, the core iron S is applied to the portion of the forward line 24 and the return line 28 from the farthest portion 26, and the farthest portion 26 is rounded toward the spiral portion 11 as shown in FIG. 2 (b). The radius r of the core iron S is appropriately selected according to the radius of curvature of the rounded portion. A front view of the round curved portions 25 and 27 after being formed in this way is shown in FIG. 2 (c). On top of that, since the resin-coated wire 21 can be elastically deformed to some extent, the hand-held hook shown in FIG. 1 can be obtained by inserting the other end portion 30 from the bent portion 29 into the spiral portion 11. 1 is completed. When the other tip 30 bent from the bent portion 29 is inserted inside the spiral portion 11, it is caught in the peaks and valleys of the resin-coated wires inside the spiral portion 11 and exerts an effect of making it difficult to pull out. To do.

3 and 4 show an example of a situation when the handheld hook 1 according to the present invention is actually used. FIG. 3 is a practical example used when a human grasps the ring 7 of the hanging strap 6, which is generally used in public transportation such as a train or a bus, without touching it with the hand 2. As an order, first, 1 to 4 fingers 3 including the index finger and the middle finger are hooked on the spiral portion 11 before and after the second joint to hold the hand-held hook 1. It is preferable to hold the farthest portion 26 so as to be located on the extension line of the arm. Then, by hooking the hook 12 on the ring 7, it is possible to support the body without touching the ring 7 itself. When a force in the direction of pulling the arm is applied, the bent finger 3 is caught by the spiral portion 11 as it is, and becomes a force of being caught by the round curved portions 25 and 27. Therefore, it is possible to support the body stably even by holding it lightly. Further, since the applied force is distributed and applied to the forward line 24 and the return line 28, the handheld hook 1 itself is not easily deformed.

FIG. 4 shows an example of a situation when the handrail 8 is made of metal or resin and is used by being hooked. The direction in which the force is applied is the horizontal direction, but it can be used in the same manner as in the embodiment of FIG. The force of hooking the finger and pulling the arm is caught by the handrail 8 at the rounded portions 25 and 27, and the body can be supported without touching the handrail 8.

Although not shown, the handheld hook 1 can be used for various other purposes. By pressing buttons such as elevator buttons, touch-type automatic doors, parking lot ticketing buttons, and route bus buzzer buttons with the round bends 25 and 27, you can operate without touching these buttons. ..

In addition, a current-carrying part layer that can be recognized by the touch panel on the outer peripheral portions of the round curved portions 25 and 27 so that the shared touch panel used in convenience stores, ATMs, vending machines such as tickets, etc. can be recognized as a touch operation. May be provided.

A second embodiment of the handheld hook 1a according to the present invention and an example of a manufacturing procedure will be described with reference to FIG. As the spiral portion 11a, a portion basically the same as the spiral portion 11 of the first embodiment is formed. The length of the spiral portion 11a (the length in the left-right direction in FIG. 5A) is about 6 cm to 9 cm. The directions of the forward line 24a and the return line 28a are different from those of the first embodiment, and extend in the vertical direction rather than the substantially vertical direction when viewed from the front surface (direction in FIG. 5A) with respect to the spiral portion 11a. Has been done. The folded portions 31a and 32a are both curved on the inside, but are formed so that the forward line 24a and the farthest portion 26a, and the return line 28a and the farthest portion 26a are all substantially right angles. That is, the spiral portion 11a and the farthest portion 26a are formed so as to be substantially parallel to each other. Further, a bent portion 29a is formed in front of the other end portion (not shown), and the other end portion is housed inside the spiral portion 11a. A front view of this state is shown in FIG. 5 (a).

Next, the core iron S is applied in the middle of the forward line 24a and the return line 28a, and the farthest portion 26 side from there is rolled toward the spiral portion 11 side to form the round curved portions 25a and 27a. A side view at this time is shown in FIG. 5 (b). With the above, the hand-held hook 1a is formed. A perspective view of the handheld hook 1a according to the second embodiment is shown in FIG. 5 (c), a plan view is shown in FIG. 5 (d), and a front view is shown in FIG. 5 (e). Compared to the first embodiment, the folded portions 31a and 32a overlap the forward line 24a and the return line 28a when viewed from the front, and give a linear impression.

A third embodiment of the handheld hook 1b according to the present invention and an example of a manufacturing procedure will be described with reference to FIG. The spiral portion 11b is basically the same as the spiral portion 11 of the first embodiment, but has a length (length in the left-right direction in FIG. 6A) of about 2 cm to 4 cm. The directions of the forward line 24b and the return line 28b are substantially perpendicular to the spiral portion 11b, but the forward line 24b and the return line 28b are formed so as to be spaced away from the spiral portion 11b. As a result, the length of the farthest portion 26b is about 0.5 cm to 1 cm longer than the length of the spiral portion 11b, and the portion where the hanging strap or the like is hooked is wider than the portion where the finger is hooked. The folded portions 31b and 32b are both curved on the inside, but are formed so that the forward line 24b and the farthest portion 26a and the return line 28b and the farthest portion 26b are at angles slightly smaller than a substantially right angle. The spiral portion 11b and the farthest portion 26b are formed so as to be substantially parallel to each other. Further, a bent portion 29b is formed in front of the other end portion (not shown), and the other end portion is housed inside the spiral portion 11b. A front view of this state is shown in FIG. 6 (a).

Next, the core iron S is applied in the middle of the forward line 24b and the return line 28b, and the farthest portion 26b side from there is rolled toward the spiral portion 11b side to form the round curved portions 25b and 27b. A side view at this time is shown in FIG. 6 (b). With the above, the hand-held hook 1b is formed. A perspective view of the handheld hook 1b according to the third embodiment is shown in FIG. 6 (c), a plan view is shown in FIG. 6 (d), and a front view is shown in FIG. 6 (e). Compared to the second embodiment, the width is narrower and less bulky. For holding straps and handrails, it is suitable for relatively strong users who can support their body with one or two fingers. Any user can easily carry it and use it beneficially if it is used only for the purpose of pressing a button instead of supporting the body.

A fourth embodiment of the handheld hook 1c according to the present invention is shown in the front view of FIG. The spiral portion 11c is basically the same as the spiral portion 11 of the first embodiment. The forward line 24c and the return line 28c are different from the first embodiment, and are formed so that the tip directions of the forward line 24c and the return line 28c are closer to each other than the direction substantially perpendicular to the spiral portion 11c. Therefore, the width of the hook portion 12c is narrower than the width of the spiral portion 11c. Further, bent portions 37 and 38 are formed so that the approaching forward lines 24c and the returning lines 28c are bent so as to be parallel to each other on the way. By the bent portions 37 and 38, the width of the hook portion 12c (the length between the round curved portions 25c and 27c) is adjusted to the spiral portion 11c while ensuring a certain distance between the spiral portion 11c and the hook portion 12c. It can be adjusted to about half the width.

A fifth embodiment of the handheld hook 1d according to the present invention is shown in the front view of FIG. The relative angles of the forward line 24d and the return line 28d are larger than those of the fourth embodiment. The bent portions 37 and 38 are not formed, and the width of the hook portion 12d is adjusted to about half the width of the spiral portion 11d.

A sixth embodiment of the handheld hook 1e according to the present invention is shown in the front view of FIG. It differs from the first to fifth embodiments in that the spiral portions 11e and 11e are divided into two parts. Since the ends of the resin-coated wire are exposed at both ends 33 and 36 on the outer side of the spiral portion 11e, make sure that the metal core wire portion is covered with resin so that the edges of the end portions do not come out. It is desirable to process it. Outward lines 24e and return lines 28e extend substantially in parallel from both ends 34 and 35 inside the spiral portions 11e and 11e, and there is no portion corresponding to the bent portion, and the round curved portions 25e and 27e remain parallel. is there. The farthest portion 26e is thinner than the other embodiments. This sixth embodiment has the advantage that the overall width is narrowed and it is not bulky, so that it is easy to carry. When using, the forward line 24e and the return line 28e are inserted between the middle finger and the ring finger, one spiral portion 11e is grasped by the index finger and the middle finger, and the other spiral portion 11e is grasped by the ring finger and the little finger. You can hold it stably.

A seventh embodiment of the handheld hook 1f according to the present invention is shown in the front view of FIG. The outward line 24f and the return line 28f are not substantially vertical to the spiral portion 11f, but extend parallel to the axial direction from the other end 23f side. The tip of the tip of the double track 28f (the portion corresponding to the other end 30 of the resin-coated wire) is stored inside the spiral portion 11f from the other end 23f side without extending to one end 22f. There is. It has the advantage of being more compact and less bulky than the third embodiment. However, since the hand cannot be fixed only by hooking the knuckle on the spiral portion 11f and the spiral portion 11f must be firmly gripped, the embodiment is suitable for a user having a relatively strong grip strength.

Hereinafter, the present invention will be described in more detail by way of examples of the present invention.

(Example 1)
Using a vinyl chloride resin-coated bonding ordinary iron wire with a total length of 1050 mm (manufactured by Twaron Co., Ltd., outer diameter 3.95 mm, iron core diameter 2.8 mm), the spiral portion and the folded portion have a shape according to the description in FIG. 5 (a). , The farthest part, the folded part, the bent part, etc. were formed. The spiral outer diameter of the spiral portion 11a is 15 mm, and the resin-coated wires are brought into substantially contact with each other and wound around a spiral around 17 to form a spiral portion 11a having a length of 70 mm. The length of the forward line 24a and the return line 28a is 125 mm. The length of the farthest portion 26a is 70 mm, which is the same as that of the spiral portion 11a. Next, a core iron S having a radius of 8 mm and an outer diameter of 16 mm was applied, and the forward and reverse lines were rounded so that the distance from the end of the spiral portion 11a to the end of the rounded portion was 90 mm to manufacture a handheld hook 1a.

When a force was applied to the spiral portion 11a and the hook portion 12a of the hand-held hook 1a to pull the hook and a pull test was performed until irreversible deformation occurred, the results were 516N and 518N for each of the two samples.

(Example 2 )

(Example 3)
In the first embodiment, the length of the wire to be used is changed to 560 mm, and from the hand-held hook 1a shown in FIG. 5, the spiral portion 11b is wound around a spiral of seven circumferences to form a spiral portion 11b having a length of 30 mm.
