Description

[Technical field]

[0001] The present invention relates to a sofa bed cover that covers the seat and back of a sofa bed. [Background technology]

[0002] In recent years, many sofa beds that can be used as a bed by reclining the backrest have been sold at online shops, etc. A sofa bed is a bed with a seat section provided on a rectangular bed base placed on the floor, and a backrest section attached to the rear of the seat section via a reclining device so that it can be freely raised and lowered. Sofa beds are fitted with sofa bed covers to protect the surface from dirt and scratches.

[0003] 2. Description of the Related Art Known conventional sofa bed covers include, for example, those that use a single stretchable sheet that covers the entire sofa bed (for example, Patent Document 1, etc.). When using a sofa bed cover, first, this large sheet is placed over the entire sofa, and then, for example, multiple push-in bars are pushed into the gaps between the seat and the backrest to prevent the cover from slipping. In addition, special suspenders are used to connect the ends of the cover to the bottom of the seat or the back of the backrest of the sofa, preventing the cover from slipping.

[0004] [Patent Document 1] Publication No. 3055540 Summary of the Invention [Problem to be solved by the invention]

[0005] By the way, a sofa bed is a device that is installed between the seat and the backrest, and can be used as a sofa by raising the backrest, or as a bed by reclining the backrest. Therefore, with conventional sofa bed covers, as the backrest rises and falls, the push-in bar would protrude from the gap between the seat and backrest, and over long-term use the suspenders connecting the ends of the cover would stretch, causing the cover to become misaligned.

[0006] Therefore, after extensive research, the inventor discovered that all of the above-mentioned problems could be solved by adopting a sofa bed cover that was not simply a single large sheet, but was made up of a seat side cover part that covered the seat between the bed base in a bag-like shape, and a backrest cover part that was connected to the seat side cover part and covered the entire backrest in a bag-like shape, and thus completed this invention.

[0007] To provide a sofa bed cover for a covering sofa bed which is unlikely to shift due to the undulations of the backrest even after long-term use and which can be easily peeled off and washed. [Means for solving the problem]

[0008] The invention described in claim 1 is a sofa bed cover for covering a sofa bed with a backrest attached freely riseable to the rear of a seat provided on a rectangular bed base, characterized in that it comprises a seat side cover part that covers the seat in a bag-like shape between the bed base, a backrest side cover part that is connected to the seat side cover part and covers the backrest in a bag-like shape, a bottom cover cloth whose base end is connected to the back side of the connecting part between the seat side cover part and the backrest side cover part and covers the bottom end surface of the backrest through the gap between the seat and the backrest, a first hanging member that hangs the bottom edge of the seat side cover part to at least the front and left and right sides of the bed base, and a second hanging member that hangs the tip of the bottom cover cloth to the backrest side cover part.

[0009] A sofa bed may be of any size, shape, structure, etc., as long as there is a gap between the seat and the backrest, and the backrest can be folded down to become a bed. The material of the bed base is arbitrary, for example, various woods, various metals, etc. The bed base may be placed directly on the floor or may be placed on a plurality of support legs. The material of the sofa bed cover (including the seat cover, back cover and bottom cover) is arbitrary. For example, it may be various kinds of cloth (including elastic fabric) or various kinds of leather (including artificial leather and natural leather). The shape and size of the lower end surface cover cloth may be arbitrary as long as it can be passed through the gap between the seat portion and the backrest portion and can cover the lower end surface of the backrest portion.

[0010] The lower edge of the seat-side cover may be hooked only to the front and left and right sides of the bed base, or to the entire peripheral side of the bed base. The first and second fastening members may be of any type, for example, various types of point fasteners (snap buttons, hooks, etc.), various types of line fasteners, or various types of hook and loop fasteners.

[0011] The invention described in claim 2 is the sofa bed cover described in claim 1, characterized in that the first fastening member and the second fastening member are each a line fastener.

[0012] The invention described in claim 3 is a sofa bed cover as described in claim 1 or claim 2, characterized in that a rubber guide string is hung between both ends of the connecting part between the seat side cover part and the backrest side cover part, serving as a guide when placing the bag-shaped backrest side cover part over the backrest part. Effect of the Invention

[0013] In the sofa bed cover of the present invention, for example, the backrest of the sofa bed is first covered in a bag shape by the backrest side cover part, and then the bottom end cover cloth extending from the back side of the joint part between the seat side cover part and the backrest side cover part is inserted into the gap between the seat part and the backrest to cover the bottom end of the backrest. In this state, the tip of the bottom end cover cloth is hooked to the backrest side cover part by the second hooking member. On the other hand, the seat of the sofa bed is covered in a bag-like shape between the bed base and the seat side cover part, and while in this state, the lower edge of the seat side cover part is hooked to at least the front and left and right sides of the bed base via the first hooking member.

[0014] This allows the seat and back of the sofa bed to be individually covered by a single sofa bed cover. As a result, even if the sofa bed cover is used for a long period of time, the cover is unlikely to shift due to the undulations of the backrest. Moreover, it is possible to provide a sofa bed cover for a covering sofa bed that can be easily peeled off from the sofa bed and washed.

[0015] In particular, according to the present invention described in claim 2, when the seat portion is covered in a bag-like shape between the bed base and the seat side cover portion, a line fastener (first hooking member) is used to hook the lower edge portion of the seat side cover portion to at least the front and left and right sides of the bed base. This allows the lower edge of the seat side cover to be hooked onto the bed base in a straight line without distortion, thereby improving the design of the sofa bed cover when in use.

[0016] According to the present invention described in claim 3, the elastic rubber guide cord is passed through the backrest, and then the backrest side cover is placed over the backrest using the guide cord as a guide. This makes it easier to attach the backrest side cover to the backrest, which is usually a time-consuming task. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] An embodiment of this invention will now be described in detail. EXAMPLES

[0019] As shown in Figures 1 and 2, a sofa bed cover 10 according to a first embodiment of the present invention is made of a single piece of stretchable fabric and is used to cover a seat portion 12 and a backrest portion 13 of a sofa bed 11 together. The sofa bed 11 has a rectangular bed base 15 as its main body, with four support legs 14 arranged at the four corners. A large rectangular seat 12 is fixed to the upper surface of the bed base 15 except for the rear end, while a long rectangular backrest 13 is attached to the rear of the seat 12 via a pair of left and right lifting devices (not shown) so that it can be freely raised and lowered.

[0020] A first tape 17, which constitutes part of a long first linear fastener (first fastening member) 16 described later, is connected (fixed) to the front upper edge and the left and right upper edges of the bed base 15. This first tape 17 is fused or glued to a predetermined location of the bed base 15 at the bed manufacturing factory, but it may also be fixed to the bed base 15 by using, for example, double-sided tape or hook-and-loop fastener when the purchaser uses the sofa bed cover. In other words, the sofa bed cover 10 of the present invention can be applied to any sofa bed. A gap 18 is formed between the rear end surface of the seat portion 12 and the lower end surface of the backrest portion 13, except for both lateral ends where the pair of left and right lifting devices are arranged.

[0021] The sofa bed cover 10 also comprises a seat side cover part 19 which covers the seat part 12 in a bag-like manner between the seat part 12 and the bed base 15, a back side cover part 20 which is integrally connected to the rear end of the seat side cover part 19 and covers the backrest part 13 in a bag-like manner, a lower end cover cloth 21 whose base end is sewn to the back side of the connecting part between the seat side cover part 19 and the backrest side cover part 20 and which covers the lower end surface of the backrest part 13 through the gap 18 between the seat part 12 and the backrest part 13, a long first line fastener 16 for collectively hanging the lower edge part of the seat side cover part 19 to the front and left and right sides of the bed base 15, and a second line fastener (second hanging member) 22 for hanging the tip part of the lower end cover cloth 21 to the lower end of the backrest side cover part 20.

[0022] These components will now be described in detail. 1 and 2, the seat side cover part 19 is a fabric body sewn into a large downward-facing square box shape with openings on the bottom surface and rear end surface. The other first tape 17A, which constitutes part of the first wire fastener 16 and has another element that meshes with an element of one of the first tapes 17 of the bed base 15, is sewn to the entire lower edge of this seat side cover part 19.

[0023] The backrest side cover portion 20 is a cloth body sewn into a rectangular box shape with only the bottom end surface being open. A second tape 23 which constitutes a part of the second linear fastener 22 is sewn to the rear end of the opening of the backrest side cover portion 20 . A roughly fan-shaped oval side cover cloth 24 is sewn to the left and right ends of the seat-side cover part 19 and the backrest-side cover part 20. The outer peripheral edge of each side cover cloth 24 is tightened with an elastic band (not shown) so that it can expand and contract according to the undulations of the backrest part 13. In addition, a long rubber guide cord 25 is hung around the middle of the outer peripheral edge of the left and right side cover cloths 24, which serves as a stretchable guide when placing the bag-shaped backrest side cover part 20 over the backrest part 13.

[0024] The lower end surface cover cloth 21 is a horizontally long rectangular cloth made of the same stretchable fabric as the seat side cover part 19 and the backrest side cover part 20. The other second tape 23A having another element that meshes with the element of one of the second tapes 23 of the backrest side cover part 20 is sewn to the tip of the lower end surface cover cloth 21.

[0025] Next, a method of using the sofa bed cover 10 according to the first embodiment of the present invention will be described with reference to Figs. As shown in Figures 1 and 2, when using the sofa bed cover 10, first, the backrest 13 is raised and the stretchable guide string 25 is passed through the backrest 13 (see Figure 3). After that, the backrest side cover 20 is placed over the backrest 13 using the guide string 25 as a guide. This makes it easier to attach the backrest side cover 20 to the backrest 13, which is usually a time-consuming task.

[0026] Next, after the backrest 13 is reclined, the lower end cover cloth 21 extending from the rear side of the connecting portion between the seat side cover part 19 and the backrest side cover part 20 is pushed into the gap 18 between the seat part 12 and the backrest 13 (see FIG. 4). After that, the backrest 13 is raised (see FIG. 5), and the lower end cover cloth 21 is pulled backward (see FIG. 6). The pulled-out lower end cover cloth 21 covers the lower end surface of the backrest portion 13, and in this state, the element sides of the two second tapes 23, 23A are butted against each other to close the second linear fastener 22. As a result, the tip of the lower end cover cloth 21 is hooked onto the lower end opening of the backrest side cover part 20 (see FIG. 7). Next, the seat side cover part 19 is placed over the seat 12 (see Figure 8), and while maintaining this state, the element sides of the two first tapes 17, 17A are butted against each other and the first line fastener 16 is closed, thereby covering the seat 12 of the sofa bed 11 in a bag-like shape between the bed base 15 and the seat side cover part 19 (see Figure 9).

[0027] This allows the seat 12 and backrest 13 of the sofa bed 11 to be individually and securely covered by one sofa bed cover 10. As a result, even if the sofa bed cover 10 is used for a long period of time, the cover is unlikely to shift due to the undulations of the backrest 13. Moreover, it is possible to provide a sofa bed cover 10 for a covering sofa bed that can be easily peeled off from the sofa bed 11 and washed. In addition, when the seat 12 is covered in a bag shape between the bed base 15 and the seat side cover part 19, the first wire fastener 16 is used to hook the lower edge of the seat side cover part 19 to the front and left and right sides of the bed base 15. This allows the lower edge of the seat side cover part 19 to be hooked to the bed base 15 in a straight line without distortion, which results in an improved design when the sofa bed cover 10 is in use. [Industrial Applicability]

[0028] This invention is useful as a sofa bed cover technology for covering the seat and backrest of a sofa bed. [Explanation of symbols]
