TECHNICAL FIELD OF THE INVENTION
The present invention relates to a shoulder pad to be used by attaching to a shoulder belt when carrying a thing such as a brush cutter or a sprayer on a shoulder using a shoulder belt.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a shoulder pad is attached to a shoulder belt when carrying a portable device such as a brush cutter, a sprayer, a bag, a camera case, a cooler case, and a caddy bag on a shoulder using a shoulder belt.
In addition, there are two types of the shoulder belt, one to be hung on one shoulder and the other to be crossed, that is, a so-called crossing. In this description, the shoulder belt used by crossing will be described.
[0003]
As shown in FIG. 10, a conventional shoulder pad 101 is formed by forming a urethane foam material into a flat rectangular parallelepiped, wrapping it with a resin sheet such as vinyl chloride, and forming a belt loop 102 for passing a shoulder belt. is there. The shoulder pad 103 is attached to the shoulder belt 103 by penetrating the shoulder belt 103 for suspending the carrying object through the belt loop 102.
Then, the person carrying the item carries the item by hanging the shoulder belt 103 with the item attached to the shoulder.
[0004]
[Problems to be solved by the invention]
Here, since the shoulder pad 101 and the shoulder belt 103 do not have a structure that can be fixed to each other, the shoulder pad 101 sometimes shifts from above the shoulder of the carrier and is often located in front of or behind the shoulder. Since the shoulder pad 101 may not be on the shoulder in some cases, the shoulder belt 103 naturally rubs directly around the neck. Since the carotid artery and jugular vein pass around this scruff, when the carrying object is a heavy object such as a brush cutter used for mowing, the shoulder belt 103 is used to rub the scruff around the scruff. May cause discomfort and pain. Further, even if the shoulder pad 101 is successfully stopped on the shoulder, the side of the shoulder pad 101 may come close to the nape of the neck and be rubbed due to crossing.
In other words, the conventional shoulder pad 101 is considered to reduce shoulder pain due to the weight of the carried object, but does not consider the discomfort and pain given to the carrier by rubbing around the nape of the neck. .
[0005]
Also, walking with the shoulder belt 103 in a state of hanging a heavy carrying object such as a brush cutter and walking while working is a problem even if the carrier is strong, even if the shoulder is painful and causes stiff shoulders. Become. This is because the weight of the article on the shoulder belt 103 is received by the trapezius of the body.
Walking and working with a prolonged strain on the trapezius muscles was painful for both the fleshy and the poor.
[0006]
In view of the above problems, an object of the present invention is to avoid discomfort and pain around the neck muscles and to provide a shoulder pad that does not burden the trapezius muscle.
Another object of the present invention is to provide a shoulder pad capable of preventing a position shift of the shoulder pad.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the first invention of the present application is directed to a shoulder pad 1 attached to a shoulder belt 2 on which a carrying object 3 can be hung by crossing with a shoulder. The shoulder crest corresponding portion 11 placed on the top, the shoulder belt attachment portion 12 for attaching the shoulder belt 2 to the shoulder crest corresponding portion 11 so as to be positioned, and the shoulder crest corresponding portion 11 on the shoulder crest K. And a pad fixing means 13 for fixing the shoulder pad.
[0008]
Further, the second invention of the present application is characterized in that, in the first invention, the pad fixing means 13 is a belt that can be wound around an arm and that can be adjusted in length. Provide shoulder pads.
[0009]
Further, the third invention of the present application is characterized in that, in the first or second invention, the shoulder belt attaching portion 12 slidably attaches the shoulder belt 2 to the acromion corresponding portion 11. , A shoulder pad according to claim 1 or 2.
[0010]
Further, the fourth invention of the present application is a shoulder pad 1 for attaching to a shoulder belt 2 capable of suspending a portable object 3, a pad body 11, and a shoulder belt attaching portion for attaching the shoulder belt 2 to the pad body 11. 12 and a belt 13. The belt 13 provides a shoulder pad characterized in that the pad body 11 can be wound around an arm while the pad body 11 is placed on the shoulder. When the shoulder belt 2 is attached to the pad body 11, the shoulder pad 1 tends to shift due to the weight of the shoulder belt 2 or the movement of a person, regardless of how the shoulder belt 2 is applied. For example, even when the shoulder belt 2 is placed on the acromion K, or when it is placed on the trapezius muscle S, the shoulder is moved as long as the person moves or the object 3 is moved. The shoulder pad 1 attached to the belt 2 is displaced by these movements. As a result, the shoulder pad 1 often moves to a position not desired by the carrier P. Therefore, in the shoulder pad 1 according to the fourth aspect of the present invention, the position of the shoulder pad 1 is prevented by providing the belt 13 that can be wound around the arm while the pad body 11 is placed on the shoulder. Shoulder pads that can be provided.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 are explanatory diagrams showing a shoulder pad of this example, FIGS. 3 and 4 are explanatory diagrams showing another example of a shoulder pad, and FIG. 6 is an explanatory diagram showing an example of a use state. It is.
[0012]
The shoulder pad 1 according to the present invention has the following structure to relieve shoulder pain when a shoulder belt 2 hanging a heavy carrying object 3 such as a brush cutter is hung on the shoulder.
The shoulder pad 1 is formed with a shoulder pad body 11 as a shoulder pad body by wrapping and sewing a soft material such as foamed urethane with a resin sheet or the like to abut on the shoulder of the carrier P. I have. The material of the shoulder pad 1 (the acromion corresponding portion 11) may be not only the above-mentioned sewing product but also a soft plastic molded product.
In this example, the shoulder belt attachment portion 12 is provided at two places on the upper surface (the surface opposite to the contact surface of the carrying person P with the shoulder blade K) 11a of the acromion corresponding portion 11 to fix the shoulder belt 2. Is provided. The shoulder belt attaching portion 12 is a flat ring-shaped member which can be opened and closed by a hook-and-loop fastener or a hook. By passing the shoulder belt 2 through the shoulder belt attaching portion 12, the shoulder belt 2 slides against the acromion corresponding portion 11. Can be mounted as possible.
Further, in addition to the above-mentioned shoulder belt attaching portion 12, a positioning belt 13 as pad fixing means is formed in an annular shape in the acromion corresponding portion 11. In this example, it is the side of the shoulder pad 1 that is located on the side opposite to the neck at the time of wearing, and is closer to the outside of the shoulder than the position where the center line of the shoulder belt 2 of the shoulder belt attaching portion 12 passes. Formed at the location. Further, in this example, the positioning belt 13 uses a belt that is smaller than the shoulder belt 2, and by winding the positioning belt 13 around the arm of the carrier, the acromion corresponding portion 11 can be used by the carrier. It does not shift with respect to the acromion K.
As shown in FIG. 8, in a narrow sense, the acromion K is located at the upper end of the shoulder, is a part of the scapula, and is located outside the trapezius S (see FIG. 9) outside the shoulder. It is located at the highest point on the shoulder as the name implies, but in the present invention, it should be understood in the meaning of a bone located on the upper shoulder outside the trapezius S.
By connecting the two belts via a so-called D ring 13a (see FIG. 5), the positioning belt 13 can be adjusted in length to fit around the arm of the carrier P.
Here, the form of the positioning belt 13 is not limited to that of the present example, and may be a material that can expand and contract, such as rubber, or may be provided with a hook-and-loop fastener instead of the D ring 13a. In advance, the length may be adjusted by changing the bonding position.
Further, the positioning belt 13 need not be a belt-shaped one, and the shoulder pad 1 may be affixed to a portion of the clothing corresponding to the shoulder ridge K by, for example, a seal-shaped one. In short, the pad fixing means (positioning belt) 13 can be implemented in various forms as long as the shoulder pad 1 does not deviate from the shoulder peak K of the carrier P.
[0013]
As shown in FIGS. 3 and 4, as a part of the acromion corresponding portion 11, a curved overhang portion 11 c is formed in an eaves shape at a position on the side opposite to the neck at the time of wearing, Three-dimensional sewing may be used. As a result, a concave portion 11d can be formed on the lower surface 11b of the acromion corresponding portion 11, although not clearly shown in the figure. Since the concave portion 11d coincides with the acromion K at the time of mounting, the acromion corresponding portion 11 can be made more difficult to be displaced from the acromion K.
[0014]
Next, a method for mounting the shoulder pad 1 according to the present invention will be described.
First, as shown in FIG. 5, the carrier P matches the shoulder belt 2 with the shoulder belt attachment portion 12 of the shoulder pad 1 and fixes it with the hook-and-loop fastener.
Next, the carrier P leans the shoulder belt 2 on the body, and attaches the shoulder pad corresponding portion 11 of the shoulder pad 1 to the shoulder pad K. Then, the shoulder pad 1 is fixed by adjusting the length of the positioning belt 13 with the D ring 13a or the like and winding the arm around the arm (especially the armpit).
Finally, the portable object 3 is suspended by the suspension portion 21 of the shoulder belt 2 so that the state shown in FIG. 6 can be obtained.
As described above, when the carrier P wears the shoulder pad 1 and winds the positioning belt 13 whose length can be adjusted around the arm, the acromion corresponding portion 11 is fixed on the acromion K without touching the vicinity of the neck. You. Therefore, discomfort and pain around the neck can be avoided.
[0015]
Conventionally, when carrying a heavy carry 3 such as a brush cutter, the shoulder belt is generally hung on the shoulder, that is, on the trapezius S when the shoulder belt is hung on the shoulder with a cross. As described above, the shoulder belt is hurt when the shoulder belt is laid on the trapezius S regardless of whether the trapezius S is fleshy or not, so that long hours of work are painful. This is because acupoints of stiff shoulders are gathered around trapezius muscle S.
On the other hand, in the shoulder pad 1 according to the present invention, the shoulder belt 2 can be always placed on the acromion K, not on the trapezius S, by the positioning belt 13. Therefore, the shoulder does not hurt even when working for a long time. This is because there is no stiff shoulder in the vicinity of the shoulder peak K.
The east and west crossing belts used to be hung from the trapezius muscle S to the neck, and they came to the present day and became accustomed to the practice of work in history. It is self-evident that shoulders are hurt when working for a long time by putting a heavy belt on the acupuncture points of stiff shoulders. By mounting it, this ancient problem can be solved.
[0016]
Next, when the carry-on article 3 is a brush cutter used for mowing work, there are many operations of swinging up, down, left and right as usual, but when this operation is performed, the positioning belt 13 and the shoulder belt attaching portion 12 are effectively used. work.
Since the weeds grow not only on flat places but also on various terrain such as slopes, the carrier P holds the brush cutter 3 with both hands and moves the tip saw (circular rotary saw blade) up and down along the terrain. Move left and right. As shown in FIG. 7, a force F <b> 1 obliquely downward is applied to the shoulder belt 2 due to the weight of the suspended work 3. Therefore, a force F2 is applied to the shoulder pad 1 in the direction of the neck. In addition, the force F2 may be amplified by the upward / downward / leftward / rightward movement at this time. Even if it is a shoulder pad without the positioning belt 13 even if it is the same form as the conventional shoulder pad or the shoulder pad 1 according to the present invention, when the brush cutter 3 is moved up, down, left and right, the shoulder F is generated by the force F2. The pad moves on its own and moves away from the shoulder, losing its role because it moves closer to the neck. However, in the shoulder pad 1 of the present invention, even if the carrier P swings the brush cutter 3 up, down, left and right, the shoulder belt 2 slides M with respect to the shoulder belt attaching portion 12 with the movement. In addition, since the positioning belt 13 is hooked and attached to the side of the person P, a force F3 is generated in the positioning belt 13 that balances the above-mentioned force F2. Thereby, the state in which the shoulder pad 1 is placed on the acromion K can be maintained. For this reason, the carryer P can work while freely swinging the brush cutter 3 without worrying about the displacement of the shoulder pad 1.
In addition, since the shoulder pad 1 contains urethane, it goes without saying that the weight of the belongings 3 felt by the carrier P is greatly reduced.
[0017]
【The invention's effect】
In the first and second inventions of the present application, the shoulder belt hanging the carrying object can be crossed, and the shoulder belt can be placed on the acromion with the positioning belt so that the shoulder pad does not contact around the neck. A heavy shoulder belt does not ride on the trapezius, greatly reducing shoulder pain. Also, even if the object is swung up, down, left and right, the shoulder pad is always fixed on the acromion.
Further, in the third invention of the present application, in addition to the effects of the above-described invention, work efficiency is actually improved because the shoulder belt moves freely with respect to the shoulder belt attachment portion with the movement of the carried object.
A fourth invention of the present application provides a shoulder pad capable of preventing a displacement of the shoulder pad by providing a belt that can be wound around the arm while the pad body is placed on the shoulder. Was made.
