MODES OF THE INVENTION

(7) Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view illustrating a bed with an exercise function according to one embodiment of the present invention, FIG. 2 is a view illustrating a state in which an upper exercise arm according to the embodiment rotates and protrudes, FIG. 3 is a view illustrating a state in which a lower exercise arm according to the embodiment rotates and protrudes, and FIG. 4 is a cross-sectional view illustrating a part of the bed with an exercise function according to the embodiment.

(8) The bed with an exercise function bed includes a main frame 4 having an upper surface 5 on which a mattress 8 and bed linen are placed and a head part 6 standing upright at an end, which is a head side of the bed, of the main frame 4 like a conventional bed as described in the drawings. However, according to the present invention, an insertion groove 12 having a cross section in a channel shape is formed along a perimeter of a front surface of the head part 6, and an upper exercise arm 14 including a horizontal bar 15 and leg parts 16 extending downward from both ends of the horizontal bar 15 is provided in the insertion groove 12. In the illustrated embodiment, the insertion groove 12 is formed along the inner perimeter of the front surface of the head part 6, but in some cases the insertion groove 12 may also be formed along a perimeter of an edge part of the head part 6.

(9) The upper exercise arm 14 is provided to be rotated forward so as to protrude from the insertion groove 12 by a rotary support part 18 such as a rotating shaft provided at a lower end of the leg part 16 and embedded in the main frame 4 or the head part 6. The rotary support part 18 may be preferably formed as the rotating shaft, but may have a suitable structure which is capable of rotatably supporting the upper exercise arm 14 and may have a shape different from that of the rotating shaft.

(10) In addition, the upper exercise arm 14 includes a rotation stopping part 19 configured to stop rotation of the upper exercise arm 14 in a state in which the upper exercise arm 14 protrudes forward at a predetermined angle. In the illustrated exemplary embodiment, the rotation stopping part 19 is formed as a control motor such as a servomotor which is shaft-coupled to the rotary support part 18 which is the rotating shaft. Accordingly, when the servomotor is automatically operated by a remote controller or operation button which is not illustrated in the drawings, and the servomotor stops after the upper exercise arm 14 rotates and protrudes at the predetermined angle, the upper exercise arm 14 may stop at a position, at which the upper exercise arm 14 protrudes, due to a stopping operation of the stopped servomotor. As described above, in the case in which the upper exercise arm 14 is driven by the control motor such as the servomotor, the servomotor which is a driving unit serves as the rotation stopping part 19. Alternately, by including a separate mechanical driving unit or stopping unit and moving the upper exercise arm 14 to a predetermined position and fixing the position, the upper exercise arm 14 is configured like an exercising apparatus such as a pull-up bar to withstand a weight of a person.

(11) Meanwhile, according to the present invention, insertion grooves 22 and 23 are formed along an edge part of the upper surface 5 which is at a leg side which faces the head part 6 of the main frame 4. Preferably, the two insertion grooves 22 and 23, which are big and small, are formed to be adjacent to and overlap each other. In addition, in the insertion grooves 22 and 23, lower exercise arms 20 and 21 respectively including horizontal bars 24 and 25 and leg parts 26 and 27 perpendicularly extending from both ends of the horizontal bars 24 and 25 are further provided. A rotary support part 28 configured to rotatably support the lower exercise arms 20 and 21 is included at lower ends of the leg parts 26 and 27. The rotary support part 28 is preferably formed as a rotating shaft, but may also be formed as another unit capable of rotatably supporting the lower exercise arms 20 and 21. In addition, the lower exercise arms 20 and 21 may also be automatically moved upward to protrude or moved downward to be accommodated by a control motor such as a servomotor. Since the lower exercise arms 20 and 21 may be rotated upward and vertically stopped such that a user performs a leg exercise while pushing the lower exercise arms 20 and 21 with feet, or a sit-up while hooking the feet on the lower exercise arms 20 and 21, or performs an exercise such as a pushup while turning over in the bed and gripping the lower exercise arms 20 and 21, the lower exercise arms 20 and 21 are convenient.

(12) In addition, according to the present invention, at least one of the plurality of lower exercise arms 20 and 21 is formed such that the horizontal bar 24 is laterally divided into a pair of horizontal bars 24a and the leg parts 26 of the horizontal bars 24a include separate elastic support units 29. Accordingly, in the case of a bed such as a double bed used by a couple, since the man and woman who have different exercise abilities can perform exercises individually while pushing the divided horizontal bars 24a with feet or pushing or pulling the divided horizontal bars 24a with hands, the couple can use the bed according to the individual exercise abilities, and thus the bed is convenient.

(13) FIGS. 5 and 6 are configuration views illustrating a bed with an exercise function according to another embodiment of the present invention. As illustrated in the drawings, peripheral part covers 32 and 34 configured to openably cover insertion grooves 22 and 23 for lower exercise arms 20 and 21 are provided in a peripheral part of an upper surface 5 of a main frame 4. The peripheral part covers 32 and 34 include a pair of side peripheral part covers 32 and a single end peripheral part cover 34. Preferably, outer ends of the peripheral part covers 32 and 34 are rotated and opened by hinges 36 disposed inside the peripheral part covers 32 and 34.

(14) In a case in which bed linen 9 such as a bed cover or blanket is placed on an outer peripheral part outside the mattress 8, when the outer ends of the peripheral part covers 32 and 34 are rotated upward and opened by the inner hinges 36 as described above, the peripheral part covers 32 and 34 are moved upward with the bed cover, blanket, and the like when being opened, and thus the lower exercise arms 20 and 21 may be easily rotated and moved upward without being hooked on the bed cover and the like and become an exercise-enabling state, or the lower exercise arms 20 and 21 may be rotated and moved downward without being interfered with the bed cover and the like, and thus the lower exercise arms 20 and 21 may be accommodated in the insertion grooves 22 and 23.

(15) In the illustrated embodiment, a front end of the side peripheral part cover 32, that is, a part adjacent to the end peripheral part cover 34 is manufactured so as to be divided into a corner cover 32a so as to be folded by hinges 37. This is for not interfering with the rotating lower exercise arms 20 and 21 in a state in which the peripheral part cover 32 is rotated and opened.

(16) FIGS. 7 and 8 are configuration views illustrating a bed with an exercise function according to still another embodiment of the present invention. Unlike the above-described embodiment, an end peripheral part cover 34a extends over an entire width of a main frame 4, hinges 38 of the end peripheral part cover 34a are disposed on an outer side of an upper surface 5 of the main frame 4, and the end peripheral part cover 34a is rotated outward and moved upward. According to such a structure, even when the end peripheral part cover 34a extends over the entire width of the main frame 4, since the end peripheral part cover 34a does not interfere with lower exercise arms 20 and 21 rotated in a state in which the end peripheral part cover 34a is opened, a corner cover 32a which is the same as that of the above-described embodiment is not necessary at an end of the end peripheral part cover 34a, and thus a bed has a simple structure and is easy to manufacture.
