Description

Wrist protector with elastic metal strip

The present invention relates to a wrist strap, and more particularly, to a wrist strap having an elastic metal strip.

Use a wrist strap to protect your wrist during gym workouts or when handling heavy objects. 1 is a plan view of a conventional wrist guard. As shown in Figure 1, the wrist protector 10 is composed of a protective pad 20 and the first and second Velcro (24, 50) surrounding the wrist. This conventional wrist protector 10 is a method in which the protective pad 20 is temporarily wrapped around the wrist, and then the second Velcro 50 is engaged with the first Velcro 24 by pulling the tension band 30 and the position is fixed.

Such a conventional wrist protector was often worn or taken off by the user himself/herself. However, it was not easy to temporarily turn the wrist guard on his left wrist and pull the tension band 30 to fasten it with Velcro. Since the protective pad 20 rotates when the tension band 30 is pulled, it was often worn while pressing with the knee or the chin.

In particular, it was difficult to securely fasten the wrist protector by itself because the wearing method for the left wrist had to be repeated for the right wrist as well. In the case of a right-handed person, it can be worn on the left wrist with the right hand, but I am not used to wearing it on the right wrist with my left hand. In some cases, it was requested to be worn by another person, but it was very inconvenient when there was no other person.

Construction of the first embodiment

Hereinafter, the configuration of the preferred embodiment will be described in detail with reference to the accompanying drawings. First, Figure 7 is a perspective view of a state in which the wrist protector 100 according to the present invention is worn on the wrist. As shown in FIG. 7 , the wrist guard 100 can be independently worn on the left wrist and the right wrist.

2 is a perspective view of a wrist guard having an elastic metal strip according to a first embodiment of the present invention, and FIG. 3 is a cross-sectional view taken in the direction A-A in FIG. 2 . As shown in Figures 2 and 3, the metal strip 150 is made of thin steel, and is configured to have a longer length compared to its width. Specifically, the ratio of width:length is 1:4 to 1:5. If the ratio is less than 1:4, the width is too thick, limiting the movement of the wrist. If the ratio exceeds 1:5, the width is too thin and cannot be easily worn using elasticity. In this embodiment, the width of the metal strip 150 is 5 cm, and the length is 22 cm.

The metal strip 150 has a curved cross-section, and is configured to be elastically wound around the wrist when an impact force perpendicular to the convex cross-section is applied in the unfolded state. The metal strip 150 was used for bracelets and the like for children.

The protective pad 110 wraps around the outer surface of the metal strip 150 and is made of fabric or TPU (thermoplastic polyurethane) in contact with the wrist 180 . TPU is urethane with the elasticity of rubber. TPU is easily flexed and elastic, and is harmless to the human body and the environment. The protective pad 110 is deformed together with the metal strip 150 .

The tensile band 120 is attached to one end of the protective pad 110 , and may have no or no elasticity in the longitudinal direction. The tensile band 120 has a width of about half that of the protective pad 110 . The tensile band 120 has a length of 5 cm to 15 cm.

The grip part 140 is formed at the free end of the tension band 120 and is configured to be easy to hold and pull by hand. To this end, the grip portion 140 may be formed by folding and sewing the tension band 120 , or may be coupled with a separate synthetic resin material or rubber.

The first Velcro 135 is a known configuration, and by surface contact with the second Velcro 130, it exerts a fastening force and can be removed by grabbing it by hand. The first Velcro 135 is attached to the concave surface of the protective pad 110 in the longitudinal direction. Since the thickness of the wrist varies according to the user, the first Velcro 135 preferably has a length of about 5 cm to 10 cm.

The second velcro 130 is attached adjacent to the grip portion 140 on the back surface (refer to FIG. 2 ) of the tension band 120 so as to correspond to the first velcro 135 wound around the wrist 180 .

Hereinafter, a method of wearing the wrist guard 100 according to the first embodiment of the present invention will be described. The user first holds the tension band 120 in the palm of the hand, and places the thumb on the protection pad 110 . At this time, the protective pad 110 becomes independent by the elasticity of the metal strip 150 .

Then, the middle area of the protective pad 110 toward the left wrist is lightly struck. Then, when an impact force perpendicular to the convex section of the protective pad 110 is applied, it is elastically wound around the wrist.

Then, the tension band 120 is rotated around the wrist 180 so that the second Velcro 130 comes into contact with the first Velcro 135 . Then, by pressing the first and second Velcro (135, 130) with your fingers to complete the coupling. For the right wrist, the above-described process is symmetrical. Since it is a process of holding the wrist protector 100 with the left hand and striking it on the right wrist 180 , even the poor left hand can surely wear the wrist protector 100 .

In the separation process of the wrist protector 100, the first and second velcros 135 and 130 are separated by hand, and then the protective pad 110 is removed and unfolded.

Construction of the second embodiment

Hereinafter, the configuration of the preferred embodiment will be described in detail with reference to the accompanying drawings. 4 is a perspective view of a wrist protector having an elastic metal strip according to a second embodiment of the present invention, and FIG. 5 is a partial cross-sectional view of the wrist protector 100 shown in FIG. is a partial cross-sectional view of the state of fastening the first and second Velcro (135, 130) in the state of Figure 5. Among the configurations of the second embodiment, the same configuration as in the first embodiment is applied as it is. Hereinafter, the characteristic configuration and operation of the second embodiment will be described.

The plurality of first hooks 160 are positioned between the other free end of the protection pad 110 and the first Velcro 135 on the concave surface of the protection pad 110 and are spaced apart from each other in the longitudinal direction. Two of the first hooks 160 form a pair and are arranged side by side, and have a sawtooth-shaped cross section. In the second embodiment, three pairs of first hooks 160 are configured. To this end, the first hook 160 may be a plastic injection product or a metal hook. The first hook 160 assists the wrist guard 100 to have a stronger tightening to the wrist 180 .

The second hook 170 is positioned adjacent to the second Velcro 130 and is configured to be caught on at least one of the plurality of first hooks 160 . Two of the second hooks 170 form a pair and are arranged side by side, and have a sawtooth-shaped cross section. In the second embodiment, two pairs of second hooks 170 are configured. To this end, the second hook 170 may be a plastic injection molding product or a metal hook. The second hook 160 assists to have a stronger tightening of the wrist protector 100 to the wrist 180 by being caught on one of the first hooks 160 .

The wearing method of the second embodiment is similar to that of the first embodiment. However, as shown in FIG. 5 , the first and second hooks 160 and 170 are engaged by pulling the grip part 140 to the end in the direction of the first arrow 190 . In a state in which the first and second hooks 160 and 170 are engaged, it is not necessary to continuously pull the grip unit 140 . Then, as shown in the second arrow 200 of FIG. 6, the first and second velcros 135 and 130 are engaged to finally complete the wearing. According to the second embodiment, since it can be pulled all the way in the direction of the first arrow 190, a more reliable wrist adhesion can be secured.

Configuration of the third embodiment

8 is a perspective view of a wrist guard having an elastic metal strip according to a third embodiment of the present invention. Among the configurations of the third embodiment, the same configuration as in the first embodiment is applied as it is. Hereinafter, the characteristic configuration and operation of the third embodiment will be described. As shown in FIG. 8 , 3 to 4 protrusion bands 210 are formed on the convex surface (opposite to the concave surface) of the protective pad 110 . The protrusion band 210 is made of regularly formed protrusions, and is formed of silicone or urethane. The interval in the longitudinal direction of the protrusion band 210 is 2-3 cm, and the protrusion band 210 is formed in the width direction of the convex surface. The protrusion band 210 has a rotation preventing function that prevents rotation with respect to the wrist by directly contacting the wrist when worn on the wrist. The protrusion of the protrusion band 210 may consist of one large protrusion.
