[1-1. Constitution]
As shown in FIG. 1, the chair cover 1 according to the present embodiment includes a back cover cover 2 that covers a backrest portion of a chair and a seat surface cover 3 that covers a seat surface of the chair. Hereinafter, the back cover cover 2 and the seat cover 3 will be described separately. In addition, in FIG. 1, the state which covered the chair cover 1 of this embodiment on the chair is represented by showing a chair with an imaginary line (two-dot chain line).

(1) Configuration of the back cover cover The back cover cover 2 is formed in a bag shape and is configured to cover the back of the chair from the top. The overall shape of the back cover cover 2 is an inverted trapezoidal shape that gradually widens from the seat surface side to the upper side. Here, for convenience of explanation, as shown by a broken line in FIG. 1, a rectangular region located in the center of the back cover cover 2 is called a back support main body 21, and is substantially triangular on the left and right sides of the back support main body 21. The region provided in the shape is referred to as a back wing portion 22.

  The size of the back cover 2 is set depending on the size of the back of the chair using the chair cover 1. The lateral width of the back support main body 21 in the back cover cover 2 is formed in a size substantially corresponding to the backrest portion of the chair. For example, if the width near the boundary between the back cover cover 2 and the seat surface cover 3 is about 400 to 450 mm, the width of the back cover main body 21 of the back cover cover 2 is the width near the boundary. It is conceivable that the film is formed with a thickness of about 400 to 450 mm. In addition, the width of the upper end portion of the back wing portion 22 may be configured to extend from the main body portion 21 to the left and right sides by about 100 mm, and to widen the entire upper end portion of the back cover cover portion 2 to about 600 to 700 mm. This number is presented as a guide only to facilitate the assumption of the optimal embodiment.

  The length of the back cover 2 in the vertical direction is configured to be about 1.5 to 2 times as high as the backrest of the chair. As for the vertical length of the back cover 2, the average of the sitting height values may be used as a reference for calculation. That is, the average sitting height of a Japanese high school third grader boy is about 92 cm, and the same girl is about 85 cm. Based on this, the vertical length from the connecting part with the seat cover 3 is 85 cm. It is good to be about ~ 95 cm.

The shape maintaining member 4 may be a wire or a wire covered with resin to have a certain degree of strength and thickness. It is not limited and can be used. Since the left and right shape maintaining member 4a is required to have a higher strength than the upper shape maintaining member 4b, a member having a larger diameter is used for the left and right shape maintaining member 4a and a smaller diameter is used for the upper shape maintaining member 4b. It is preferable to use a member. However, this means an optimal configuration. As another aspect, the left and right shape maintaining member 4a and the upper shape maintaining member 4b are not provided separately, and are configured by a single shape maintaining member 4 having the same strength. It is also possible.

  Further, as shown in FIG. 1, the left and right shape maintaining member 4 a is provided to extend from the left and right side portions of the back cover cover portion 2 to the left and right side portions of the seat surface cover portion 3. That is, the part from the seat surface of the chair to the backrest is generally bent at an angle of about 90 ° to 100 °, but the shape maintaining member 4 is covered with the seat surface from the left and right sides of the back cover cover 2. By providing the position up to the left and right side portions of the portion 3, the chair cover 1 can be installed in accordance with the bending of the seat surface and the backrest portion of the chair.

The inner cover 11 is fixed so as to fit completely inside the outer cover 12. Note that the pieces of the inner cover 11 and the outer cover 12 are fixed to each other by a known method such as sewing, bonding, and pressure bonding.

[1-2. Effect]
The operation of the chair cover 1 of the present embodiment configured as described above will be described.
(1) Chair mounting method The chair C used in the present embodiment has, for example, a leg portion formed of a square steel pipe, a seat surface and a backrest formed of beech molded plywood, and a seat surface height of 420 mm from the floor. Assume that the seating surface width is 420 mm, the seating surface depth is 580 mm, and the height of the upper end of the backrest is 785 mm from the floor (see FIG. 1). A chair cover 1 is prepared in accordance with the shape of the chair C.

  First, the back cover cover 2 of the chair cover 1 is placed on such a chair C so as to wrap the backrest portion of the chair. At this time, since the back cover cover portion 2 is formed in a bag shape, the backrest portion of the chair C is completely covered (see FIG. 1A).

  After the back cover cover 2 is mounted on the backrest portion of the chair C, the shape maintaining member 4 of the chair cover 1 is bent according to the curve of the connecting portion between the backrest and the seat surface of the chair C. Thereby, the lower end part of the back cover cover part 2 of the cover 1 for chairs is positioned, and the covering condition with respect to the backrest of the back cover cover part 2 is adjusted.

  Next, the seat surface covering portion 3 is fixed to the seat surface of the chair C. First, the main body portion 31 of the seat surface covering portion 3 is brought into contact with the seat surface of the chair C (see FIG. 1A). In this state, the left and right fixing portions 32a and 32b, the front fixing portion 33, and the rear fixing portion 34 of the seat surface covering portion 3 are not yet fixed, and are hung down in the front-rear and left-right directions of the seat surface (the state in FIG. 5). ). At this time, the chair cover 1 is in a state where the inner cover 11 shown in FIG. 3 is completely covered with the outer cover 12 shown in FIG. 5, and the pieces c and d of the inner cover 11 are fixed to the left and right. It is in the state which hung down inside 32a, 32b.

Based on this premise, hereinafter, the folding procedure of the fixing portion will be described. First, c and d of the inner cover are fixed to the fixing member F (see FIG. 3). Subsequently, a fixing member F (for example, a male surface fastener) provided at the front ends of the front fixing portion 33 and the rear fixing portion 34 is replaced with a fixing member F (for example, a female surface fastener) provided on the inner cover. Fix to fit. Thereafter, the left and right fixing parts 32a and 32b are closed so as to cover the front and rear fixing parts 33 and the rear fixing part 34, and the fixing members F of the left and right fixing parts 32 are combined (see FIG. 5 so far).
Thereby, as shown to Fig.1 (a), the seat surface covering part 3 is fixed so that a seat surface may be wrapped from the front and back.

(2) Usage pattern The following usage pattern can be considered about the cover 1 for chairs of this embodiment with which it mounts | wears with respect to the existing chair C as mentioned above.

(2-1) Usage pattern 1 (backrest stretching)
The usage pattern 1 is a case where the back cover cover 2 is used in an upright state, as shown in FIG.
In this pattern, in the chair C, the backrest that was only about half the height of the user's back can be extended to a position that covers the user's head. At this time, since the shape maintaining members 4 are inserted into the left and right sides of the back cover cover 2, the stretched backrest is kept upright in the chair cover 1. In addition, the inner cover of the chair cover 1 is made of a non-woven fabric such as a felt material having a certain degree of hardness. Therefore, in combination with the stress of the shape maintaining member 4, the user can sit on the back of the chair. The back cover cover 2 firmly receives the head and does not deflect the user's head backward.

  At first glance, the strength of the inner cover 11 and the strength of the shape maintaining member 4 are considered to be insufficient to hold the weight of the user, but generally the weight of the user is the most against the backrest of the chair. The hanging portion is around the lower part of the user's scapula, and this portion is held at the upper end of the backrest, which is the original component of the chair C. And even if the user leans greatly on the backrest, the shoulder, neck and head above the user's shoulder blade will not bend more backward than the shoulder blade (see the image diagram in Fig. 7). ). Therefore, the weight applied to the backrest of the chair cover 1 is about the weight of the user's head, and if this weight is sufficient, the weight is sufficiently supported by the strength of the inner cover 11 and the strength of the shape maintaining member 4. Is possible.

(2-2) Usage pattern 2 (blindfolding action)
As shown in FIG. 6B, the usage pattern 2 is a mode in which the usage pattern 1 is improved and is a usage pattern in consideration of the user's concentration.
That is, the back support wing 22 portion protruding in the left-right direction from the back support main body 21 of the back support cover 2 is used by bending inward. At this time, since the shape maintaining member 4 is inserted along the contour at the upper edge of the back cover cover 2, it is possible to maintain the bent state of the back wing 22 inside. Become. Thereby, as shown in FIG. 7, the left-right direction of a user's head can be covered with the back cover cover part 2. FIG. Therefore, the back cover 2 can hide the user's field of view from the lateral direction, and can increase the user's concentration with respect to the front.

(2-3) Usage pattern 3 (back cushion effect)
As shown in FIG. 6C, the usage pattern 3 is a pattern in which the back cover cover portion 2 is used while being tilted to the front seat surface side.
Since the shape maintaining members 4 are inserted in the left and right side portions of the back cover cover 2, the back cover cover 2 can be folded with the lateral direction as a crease at an appropriate position in the height direction. . In this case, if the back cover cover 22 is folded back to the seat surface side of the chair C, the folded back cover cover 2 has a cushioning effect due to moderate stretchability by the shape maintaining member 4.

  In the usage pattern 3 as described above, the chair cover 1 of the present embodiment is used for a normal chair C made of a conventional plywood and a steel pipe, thereby changing the shape of the chair and increasing the cushioning property. In addition to bringing about dramatic changes, it is also possible to reproduce a profound design like a sofa, and the design is extremely high.

(2-4) Usage pattern 4 (use as a normal chair)
As shown in FIG. 6 (d), the usage pattern 4 is a pattern in which the back cover cover 2 is used while being tilted in the direction opposite to the seating surface side that is the rear.
If the back cover cover 2 is folded back to the side opposite to the seat surface side, the folded back cover cover 2 is not used when sitting on the chair C, and the normal backrest height of the chair C is realized. be able to.

  In the usage pattern 4 as described above, the chair cover 1 of the present embodiment is used for a normal chair C made of a conventional plywood and a steel pipe, thereby changing the shape of the chair and causing a functional change. In addition, the folded back support cover 2 can give the backrest a profound feeling, and the design and form can be greatly changed by a simple method of simply covering the chair cover 1.

(3) Effects According to the present invention as described above, a novel cover for a chair that brings about a great change in the function and design of the chair that has been used so far, without having to replace the chair simply by placing it on an existing chair. 1 can be provided.

  That is, since the back cover cover 2 that covers the back portion of the chair is configured to be higher than the height of the back portion, even if the back of the existing chair is formed low, it is changed to a chair with a high back. It becomes possible to do. At this time, since the shape maintaining member 4 is provided on both sides of the back cover cover 2, even when the height of the back cover cover 2 exceeds the height of the back of the chair, the shape of the back cover Is maintained in the rising direction of the backrest.

  In addition, the shape maintaining member 4 is configured by a member that can be freely bent and deformed, for example, a pipe-shaped interlock tube, a wire having a certain diameter, or a combination of a wire and a member that covers the wire. The cover 2 can be bent at a suitable position in the height direction with a direction perpendicular to the height direction as a fold. In this case, when the back pad portion is folded back to the seat surface side, the folded back pad cover 2 serves as a cushion. On the other hand, if the backrest portion is folded back to the side opposite to the seat surface side, the folded backrest cover 2 is not used when sitting on the chair C, and the height of the backrest of the normal chair C is increased. Can be realized.

  Moreover, the cover 1 for chairs can be reliably fixed with respect to the chair C by covering the seat surface of the cover 1 for chairs with the main-body part, the right-and-left fixing part, and the front part.

  Furthermore, by providing the shape maintaining member 4 at the upper end of the back cover cover 2, the shape of the chair cover 1 in this portion can be maintained. When the user sits on the chair C on which the chair cover 1 of the present invention is installed, the head is located near the upper end of the back cover cover 2. Therefore, by bending the upper left and right sides of the back cover cover 2 inward, for example, the left and right directions of the user's head can be covered, and the user's field of view can be hidden from the horizontal direction. Can be enhanced (see FIG. 7).

  Further, by forming the back cover cover portion 2 gradually and gradually toward the upper portion, when the upper left and right side portions of the back cover cover portion 2 are bent inwardly, the blind cover effect from the lateral direction can be obtained. Get higher.

  Further, the portion from the seat surface of the chair C to the backrest is bent at an angle of about 90 ° to 100 °. However, the shape maintaining member 4 extends from the left and right sides of the back cover cover 2 to the seat surface cover 3. By being provided up to the left-right side part, the cover 1 for chairs can be installed according to the bending of the seat surface and the backrest part of the chair C.

  The chair cover 1 is divided into a base part made hard to some extent by a thick non-woven fabric and a surface part covering it, and by providing this together, the material of the surface part, for example, leather material Since the design can be selected with more emphasis on functionality than suede material or fabric, the degree of freedom in designing the entire chair cover 1 is increased.

[3. Other Embodiments]

For example, as shown in FIG. 8, it is also possible to provide a belt-like body B that can be fastened and relaxed between the back cover cover 2 and the seat surface cover 3 and at the boundary between the backrest and the seat surface. . As a result, the band B is aligned at the boundary between the backrest and the seating surface, and the band B is clamped and fixed by the band B, so that the band B serves as a positioning reference. 2. Determination of the lower end position is facilitated, and adjustment of the covering condition of the back cover cover 2 is facilitated.

  Further, even when the width of the back cover cover 2 is excessive with respect to the width of the boundary between the seat surface of the chair and the backrest, the back cover 2 can be tightened against the boundary by the band B. Since it can, the size can be adjusted. Furthermore, the band B can be used as an accent for the design of a chair covered with a chair cover, for example, by using a different color or tone for the color scheme or decoration of the chair cover. is there. In addition, as the strip | belt-shaped body B, as long as the boundary part of the above-mentioned back cover cover part and the seat surface cover part 3 can be clamp | tightened, any thing can be used. For example, the belt-like body B can be constituted by a rubber band, or can be constituted by a belt or a strap that can adjust the tightening degree.

  The positioning for adjusting the covering degree of the back cover cover 2 is performed not only at the boundary between the chair back and the seat surface by the shape maintaining member 4 or the above-described band B, but also at the upper end of the back. It is also possible.
