Description

  The present invention relates to a heat insulation cover from the lower limbs to the abdomen used while sitting on a chair, and more particularly to a heat insulation cover suitable for use by a wheelchair user when going out.

  Kneeling is widely used as a thermal insulation cover for the lower limbs used while sitting on a chair. The lap can be used in the form of a bag with the upper side wrapped around the waist, but in order to do so, it must be raised once. Moreover, since the bag formed in this way is a bag without a bottom, the air | atmosphere will enter into a foot tip and heat insulation is not enough. For example, Patent Document 2 proposes a heat insulating cover that wraps a foot by folding a folded piece provided on a lower side of a bag without a bottom that wraps a leg and fastening it with a surface fastener or the like.

  It is not possible to keep the back side of the leg warm by simply placing a single lap on the knee, and it is not sufficient as a heat-insulating cover that is particularly used when a wheelchair user goes out. In order to solve this problem, for example, Patent Documents 1 to 3 propose a heat insulating cover in which a portion covering a leg has a bottomless or bottomed bag.

  The one described in Patent Document 1 uses a quilted heat-insulating fabric, a folded bag-shaped bottomed bag, and the entrance extending to the back of the knee is wider than the bottom, naturally opening both knees and applying external pressure. A structure that allows the upper side to be bound with an elastic string to prevent outside air from entering from the upper side of the bag body into which the lower part of the knee is inserted, with the lid part extended to the waist and extended to the knee. It is said.

  The thing of patent document 2 consists of a bag open | released up and down, is equipped with the folding | turning part in a lower terminal, and wraps the whole leg including a toe. A split part is formed on the front part from the upper part to the lower part, and this is joined with a fastener or the like, and the folded part is fixed with a hook and loop fastener or the like, and a notch part is formed on the upper part of the back part. The caregiver can easily put on the user while sitting on the wheelchair. That is, the bag body has a two-divided structure that is divided into left and right sides, and the bag body is formed by connecting the two opposing sides with fasteners.

  The thing of patent document 3 is the length of the size which covers the lower body front of a person for the purpose of providing the lap which can also be kept warm, and can be made to wear easily in the sitting state. A horizontal band is provided at the bottom of the back of the main body, which is formed into a rectangular shape, and a bag is formed with the main body and the horizontal band opening up and down, and the main body is extended below the position corresponding to the lower edge of the horizontal band. It is said that it was installed and used as the instep cover. This kneeling is considered to keep the back of the lower limb warm, but is not considered to prevent the outside air from entering from the lower side and the upper side of the bag.

Utility Model Registration No. 3039232 Japanese Patent Laid-Open No. 10-292212 JP 2003-116694 A

  As described above, a knee-hanging or heat-insulating cover provided with a bag into which a lower portion from below the knee or above the knee is inserted is known. Since the air in the bag warmed by the body temperature flows upward and replaces the outside air, it is important for heat insulation to close the gap between the upper side of the bag and the leg when worn. The thing of patent document 1 is made to perform the closure by tying it with a string, and the thing of patent document 2 is made to close and perform a fastener. The thing of patent document 3 is not considered about this point.

  In addition, it is obvious that these kneelings that cover the entire portion from the upper part of the knee to the lower part and the front surface of the thigh are not sufficient as a heat insulating cover used when the wheelchair user goes out. If the length of the bag body is made longer and the upper part of the bag is placed in the bag, the heat from the thigh to the abdomen will be sufficient, but the disabled person who cannot stand up from the chair It is difficult for a caregiver to wear such a warm cover by lifting the body of the wheelchair user.

  The present invention relates to a heat insulating cover having a bag body covering the entire circumference of the lower part of the chair, particularly a user sitting on a wheelchair, and warm air in the bag body escapes from an opening on the upper side of the bag body. It is an object to obtain a heat insulation cover that can prevent heat from standing on a chair and lift the body without having to stand up and lift the body from the knee to the abdomen with a simple work. .

  The heat insulation cover of the present invention is formed of a flexible sheet having heat insulation as a whole, and has a front surface portion 4 having a vertically long rectangular shape, and a bag body 3 having the lower half portion 41 of the front surface portion as a front surface, The wing part 5 is provided to extend on both sides of the upper half part 42 of the front face part 4 beyond the side of the bag. The wing part 5 covers the body side of the wearer in a state in which the wearer sitting on the chair inserts both legs into the bag 3 and covers the front of the thigh or the front of the abdomen with the upper half 42 of the front part. The width of the side edge 51 can be inserted between the back of the outer side or the back of the side of the abdomen and the seat plate or back of the chair.

  The bag body 3 is formed by connecting the both sides and the lower side of the front lower half part 41 and the both sides and the lower side of the back part 6 having the same shape and the same size as the front lower half part 41, either integrally or by sewing. Can be formed. In addition, a bag body equivalent to this is such that the back surface portion 6 having the same width as the lower half portion and the overlapping portion 7 having substantially the same width are connected from one side of the front lower half portion 41 to the side, The back surface portion 6 and the overlapping portion 7 can be formed by folding them back to the back surface of the lower front half portion 41 and further overlapping the overlapping portion 7 so as to overlap the lower half portion 42.

  The heat insulation cover having the above structure puts legs into the bag body from the upper side of the bag body 3 while the user is sitting on the chair, and lifts the upper side of the bag body until it abuts on the front edge of the seat plate of the chair. More preferably, the upper side 61 of the back surface portion is inserted between the back surface of the user's thigh and the seat plate of the chair, and in this state, the front upper half 42 is spread from the front surface above the knee of the user to the front surface of the abdomen. By manually inserting the side edge (outer side) 51 of the portion 5 into the gap between the user's body and the seat plate and the backrest, the front and sides of the body from the user's knee to the abdomen are wrapped. .

  By folding the upper sides of the front surface portion 4 and both wing portions 5 downward by an appropriate length when worn, it is possible to adjust how much the body is wrapped up. If the vertical dimension of the thermal insulation cover is lengthened, the part from the user's feet to the armpit can be wrapped and kept warm, and if the thermal insulation cover, muffler and gloves of this invention are worn, the winter season Wearing a short overcoat that is warm enough outdoors and can be worn while sitting is sufficient to keep warm enough to go out in a wheelchair during the severe winter season.

  The heat insulating cover of the present invention that is preferable for manufacturing is a rectangle (a broad rectangle including a square) having a vertical dimension in which the upper half 42 of the front portion is equal to or slightly longer than the lower half 41, and the rear portion 6 It is a rectangle having the same vertical dimension as the lower half, and the wing part 5 is a vertically long rectangle having the vertical dimension equal to or slightly shorter than the upper half.

  The flexible sheet having heat retaining properties is preferably a quilting sheet formed by sewing a front cloth and a back cloth sandwiched with batting or feathers along a rectangular lattice-shaped sewing line. In this case, there is a horizontal sewing line 22 at a position slightly below the center in the vertical dimension of the front surface portion 4, and the front upper half portion 42 and the wing portion 5 on the extension of the side 31 of the bag body 3. It is preferable that a vertical sewing line 21 exists at the boundary.

  With such a structure, manufacturing is extremely easy, and waste due to uncut portions in the heat-retaining sheet as a material does not occur. Further, when not in use, the wing part 5 is folded inward, and the front upper half part 42 and the front lower half part 41 are folded so as to overlap each other with the folded wing part 5 interposed therebetween. If a quilting sheet, especially a quilted sheet with feathers is used as the heat retaining sheet, an extremely high heat retaining effect can be obtained, and the quilting sheet can be folded compactly in the above manner by adjusting the vertical and horizontal sewing lines to the above positions. be able to.

  According to the heat insulation cover of the present invention, in the heat insulation cover provided with the bag body surrounding the entire circumference of the lower part from the upper part of the user sitting on the chair, without using an extra thing such as a string or a fastener, It is possible to more reliably prevent the warm air in the bag from escaping from the upper side of the bag body with a simple operation. Accordingly, it is possible to more completely retain the heat from the upper part of the knee to the lower part. Furthermore, it is possible to provide a heat insulating cover that can wrap and heat the entire circumference of the upper thigh and abdomen above the knee and the entire circumference of the torso from the armpit.

  It should be noted that the back of the upper thigh and the back of the torso above the knees while sitting on the chair is kept warm by the seat plate and back of the chair, and the side edge of the wing part 5 of the heat insulation cover of the present invention. By inserting the side between the seat plate and backrest and the user's body, the seat plate and backrest of the chair and the heat insulating cover of the present invention keep the entire circumference of the user's body wrapped. It is.

A perspective view of the bag from the back side in a slightly stretched and flat state Perspective view of the cut sheet before sewing Side view showing the state of the insulation cover when worn Rear view showing the state of the insulation cover when worn The perspective view which looked at the 2nd example from the back side in the state extended flatly

  Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 are views showing the first embodiment, FIG. 1 is a perspective view of a state in which a bag is slightly expanded and flattened as viewed from the back side, and FIG. 2 is a heat insulating material cut before sewing. The perspective view of a sheet | seat, FIG.3 and FIG.4 are the side view and the rear view which showed the state of the heat insulation cover at the time of wear.

  As shown in FIG. 2, the heat insulating cover 1 of the first embodiment is manufactured by sewing two heat insulating sheets 2a and 2b cut into a rectangular shape. The heat insulating sheets 2a and 2b in the figure are feathered quilting sheets, and the sewing line between the lining and the outer material is shown by dotted lines in FIGS. In the dotted line in FIG. 1, 21 is a vertical sewing line on the extension of the side 31 of the bag body 3, and 22 is a horizontal sewing line in the center of the vertical dimension of the front surface portion 4. The line 22 is also a sewing line for sewing the cutting sheets 2a and 2b.

  The bottom cut body 3 is formed by folding the second cut sheet 2b of the two cut sheets 2a and 2b shown in FIG. 2 into two vertically and sewing both sides. One side of the bag body is used as the front lower half 41, and the upper side and the lower side central part of the first cutting sheet 2a are sewn together so that the front upper half 42 and the front lower half 41 are connected. Thus, a vertically long front surface portion 4 is formed. The portions on both sides of the first cutting sheet 2a, whose lower sides are not sewn to the second cutting sheet 2b, become the wing parts 5.

  The vertical dimension of the first cutting sheet 2a is slightly longer than ½ of the vertical dimension of the second cutting sheet 2b. Therefore, the vertical dimension of the bag body 3 formed by folding the second cutting sheet 2b up and down is slightly shorter than the vertical dimension of the front upper half 42 which is the upper half of the front part 4. This is because the thickness of the heat insulating sheet is taken into consideration, and the sides are aligned when folded. The width dimension w1 of the wing part 5 is shorter than ½ of the width dimension w2 of the front face part 4. In the example of the figure, the width dimension w1 of the wing part 5 is 1/3 of the width dimension w2 of the front face part 4.

  In the heat insulating cover of the first embodiment shown in FIG. 1, both wings 5 are folded inward at the position of the sewing line 21, and the front upper half 42 and the front lower half 41 are overlapped at the sewing line 22. When folded, a rectangular folded shape is obtained.

  Arrows A1 and A2 in FIGS. 3 and 4 indicate directions in which the upper side 61 of the back surface part 6 and the side edge 51 of the wing part 5 are inserted between the user's body and the seat plate and backrest of a wheelchair (not shown) when worn. ing. The user's foot sitting in the wheelchair is lifted from the footrest, put into the bag body 3 from the upper opening of the bag body 3, the upper side of the bag body 3 is pulled up, and the upper side 61 of the back part reaching the back side on the knee. Is inserted between the back of the user's thigh and the seat plate as shown by an arrow A1. At this time, the portions on both sides of the upper side 61 are pushed toward the inside (the center side in the width direction) of the seat plate.

  Then, the front upper half 42 is spread over the front of the user's thigh and the front of the abdomen, and the sides of the user's thigh and torso are wrapped by the side portions of the front upper half 42 and the wings 5 extending laterally therefrom. Then, the side edge 51 of the wing is pushed inwardly as indicated by an arrow A2 between the user's body and the wheelchair seat and backrest.

  Thus, when the side edge 51 of the wing part 5 is inserted between the user's body and the seat plate and the backrest of the chair, the thermal insulation cover of the present invention and the seatboard and the backrest of the wheelchair lower the user's torso. These portions are encased and the portions are kept warm, and the warmed air in the heat insulation cover 1 is difficult to escape upward, so that a very excellent heat retaining effect is obtained.

  The bag body 3 can also be formed like a wound skirt. FIG. 5 is a view showing an example thereof, and is a perspective view seen from the back side in a state where the heat insulating cover of the second embodiment of the present invention is extended flat. In FIG. 5, the same members as those in the first embodiment are denoted by the same reference numerals. Hereinafter, differences from the first embodiment will be described.

  The heat insulating cover 1 of the second embodiment includes a first cut sheet 2a having the same shape and the same size as the first embodiment, and a second cut sheet 2b having the same vertical dimension as the first cut sheet and having a width twice as large. It is manufactured by sewing. As for the 2nd cutting sheet 2b, the one edge part side of the upper side 24 is sewn on the center part of the lower side 25 of the 1st cutting sheet 2a.

  The center of the first cutting sheet 2a, the lower part of which is sewn to the upper side 24 of the second cutting sheet, becomes the front upper half 42, and the both sides of the first cutting sheet 2a become the wing parts 5 as in the first embodiment. The same. The surface of the second cutting sheet 2b on the end side where the upper side is sewn to the first cutting sheet 2a is the front lower half 41, the adjacent portion of the same width is the back surface 6, and the outer side is the same. The width portion becomes the overlapping portion 7. The overlapping portion 7 is a portion that is overlapped with the front lower half 41 to form the front surface of the bag body 3 when worn.

  A folded piece 62 for closing the lower end of the bag body is sewn on the lower side of the back surface portion 6, and the folded piece 62 is placed on the inner surface of the folded piece and the lower front side of the front lower half 41. Fastening fasteners 63 and 63 are attached.

  In the heat insulation cover of the second embodiment, a portion where the front upper half 42 and the lower front half 41 are sewn is positioned on the knee of the user sitting on the chair, and the front portion 4 is placed on the user's knee. Spread it from the front of the trunk to the front of the legs. Then, the back surface portion 6 is turned from the user's knee to the back surface of the lower leg portion, and the overlapping portion 7 is overlapped on the front lower half portion 41 to form a bag body like a wound skirt, and folded. By folding the piece 62 and joining the surface fasteners 63, 63, a bag body for wrapping the legs is formed. Thereafter, as described with reference to FIGS. 3 and 4, as indicated by arrows A 1 and A 2, the upper side 61 of the back surface and the side edges 51 of both wings 5 are placed between the user's body and the seat plate and backrest of the chair. Insert and wear the lower part of the user's torso.
