Description

  The present invention relates to a waist protection pad used to relieve external force applied to the waist, and in particular, for shorts, girdles, or sports for protecting the iliac crest and the greater trochanter that are susceptible to impact when falling. The present invention relates to a waist protection pad suitable for wearing with spats or the like.

As a protective device for fracture protection that can be easily attached to a part that is susceptible to impact on the waist, it is a plate-shaped synthetic resin that is integrally formed by embedding a flexible sheet that is not easily torn along a wide surface. And a second component made of a synthetic resin that is integrally laminated on one wide surface side of the first component and is softer than the first component and has low resilience. There is known an impact absorbing pad made of (see Patent Document 1).
JP 2001-123111 A

  However, in the conventional art described in Patent Document 1, the side end of the pelvis, that is, the iliac crest that is easily damaged during a fall, and the upper end of the femur constituting the hip joint, that is, the greater trochanter, are roughly divided. Although it has a shape that covers the body, the contact surface with the body is somewhat curved, but as a whole it is flat, and the entire surface of the pad touches the body when worn, and breathability is It is low and the followability to the movement of the thigh is low, and a comfortable wearing feeling is not always obtained.

  In view of such problems of the prior art, it is lightweight and flexible, has good fit to the body during exercise of the thigh, and has excellent breathability, so as not to give a sense of incongruity even when worn for a long time. In order to provide a waist protection pad that can be easily attached and detached according to the present invention, claim 1 of the present invention provides a waist protection pad (1) to be applied to both sides of the waist, with a flexible flat base ( 2), an upper convex portion (3) made of an elastic material projecting from a portion facing the iliac crest (11) at the time of mounting on one surface of the base, and one surface of the base It is provided with a lower convex part (4) made of a highly elastic material projecting at a position facing the greater trochanter (12) when mounted, and the upper convex part and the lower convex part are It was supposed to be divided into

  According to a second aspect of the present invention, the upper convex portion is divided into a plurality of portions by a vertically oriented line (gap 5).

  Further, according to a third aspect of the present invention, the base portion and the respective convex portions are integrated by heating by sandwiching a foamed resin material or a gel-like substance with a woven cloth or a non-work cloth (7a, 7b) with a mold. It was supposed to be molded.

  According to the first aspect of the present invention, since the upper convex portion facing the iliac crest and the lower convex portion facing the greater trochanter are easily bent along the horizontal dividing line, The followability to the movement of the leg is increased, and it becomes difficult to shift when worn. According to the second aspect of the present invention, the upper convex portion can be easily bent along the iliac crest along the vertical dividing line, so that it is possible to enhance the fit to the curve around the waist. In addition, a gap is formed between the convex portions that are divided and adjacent to each other, and a ventilation function is obtained thereby, which is effective in enhancing the comfort at the time of wearing. Furthermore, according to claim 3 of the present invention, since the pad can be easily molded as a single body, handling is simple, high versatility is obtained, and the outer surface can be flattened without impairing cushioning properties. The influence on clothes can be reduced.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows a typical form of a waist protection pad constructed according to the present invention as seen from the front. This waist protection pad 1 is composed of a flat base portion 2 having an egg-shaped or empty bean-shaped outer shape at the top, and a plurality of convex portions 3 and 4 projecting from one surface of the base portion 2. Thus, a pair of left and right is set as one set. The pair of left and right are opposite, and the center of the upper part is somewhat biased backward. The upper convex portion 3 is divided into, for example, five portions by a vertical dividing line, and a gap 5 is formed between adjacent ones. And the lower convex part 4 has comprised the circular outline shape seen from the front. Moreover, the cross-sectional shape seen from the side of these convex parts 3 and 4 has comprised the substantially semi-elliptical shape as shown in FIG.2 and FIG.3.

  As shown in FIG. 4, the base 2 and the convex portions 3 and 4 are made of, for example, a soft foamed polyurethane resin material, or a highly elastic material 6 such as a gel-like material, from a woven or non-woven fabric that is rich in elasticity. It is integrally molded by wrapping with outer skin materials 7a and 7b, and sandwiching and heating with a mold.

  Appropriate dimensions of the base 2 are a thickness of 3 to 7 mm, a width of 150 to 190 mm, and a height of 200 to 250 mm. Moreover, the range of 15-30 mm is suitable for the protrusion dimension from the base part surface of the convex parts 3 * 4.

  As shown in FIGS. 5 and 6, the waist protection pad 1 is used by being applied to the side surface of the waist, and at this time, the surface from which the protrusions 3 and 4 protrude is arranged toward the body side. When the lower back protection pad 1 is mounted at the position shown in the figure, the upper convex part 3 vertically divided into a plurality of parts is opposed to the iliac crest 11 whose position hardly changes during walking or exercise. The lower convex part 4 which makes a circle faces the greater trochanter 12 having a large change in position.

  By attaching the waist protection pad 1 to this position, the iliac crest 11 and the greater trochanter 12 are protected from shocks caused by the fall by the buffering action due to the elasticity of both convex portions 3 and 4, and the upper and lower convex portions 3 and 4 are protected. Since the flat portion of the base 2 between the four is easy to bend, the movement of the greater trochanter 12 due to the movement of the thigh is not hindered, and the upper convex portion 3 facing the iliac crest 11 is a vertical line Since it is divided, the waist protection pad 1 fits around the waist while the upper protrusion 3 hits the iliac crest 11, and the ventilation action is obtained by the gap 5 between the protrusions, so that a comfortable wearing feeling Is obtained.

  As shown in FIG. 7, the upper convex portion 3 may be divided into at least two parts, and the contour shape viewed from the front of the lower convex portion 4 is a donut shape with a depressed central portion as shown in FIG. But it ’s okay. Further, the contour shape of the side section of each of the convex portions 3 and 4 may be a trapezoid (see FIG. 7).

  The base part 2 and the convex parts 3 and 4 are not only molded with the same material 6 as shown in FIG. 3, but also with different materials overlaid as shown in FIG. The material 8 of the base 2 may be somewhat stiffer than the material 6 of the parts 3 and 4, and as shown in FIG. 9, a thin flat plate 9 made of synthetic resin is used as a core plate to line the convex parts 3 and 4 It is good also as the form which did.

It is a front view which shows the typical example of the waist | hip | lumbar part protection pad by this invention. It is sectional drawing which follows the II-II line | wire in FIG. It is sectional drawing which follows the III-III line in FIG. It is a principal part expanded sectional view of a waist protection pad. It is a rear view which shows the mounting state to a body. It is a side view which shows the mounting state to a body. It is a front view which shows the modification of the waist | hip | lumbar part protection pad by this invention. It is principal part sectional drawing of another modification. It is principal part sectional drawing of another modification.
