Description

[Technical Field]

[0001] The present invention relates to a foldable folding bed. [Background technology]

[0002] BACKGROUND ART Foldable folding beds have been known in the past (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-245573 Summary of the Invention [Problem to be solved by the invention]

[0004] Because conventional folding beds are foldable, when switching between folding and unfolding, care must be taken to avoid the movement of the bed frame. For example, just before the bed is fully opened, the weight of the bed causes the speed of the opening to increase dramatically, so care must be taken to firmly grip the bed with the hands just before the opening is completed. SUMMARY OF THE INVENTION In view of the above, the present invention aims to provide a folding bed that allows for easier switching of the state than conventional folding beds. [Means for solving the problem]

[0005] To achieve the above objectives, the folding bed of this invention is: a pair of bed halves whose opposing ends are connected to each other so as to be rotatable about a first rotation axis extending horizontally; leg bodies provided on the bed halves so as to be rotatable about second rotation axes parallel to the first rotation axis; Equipped with At least one of the legs is connected to the bed half via a rotary damper that damps rotation about the second axis of rotation.

[0006] With this configuration, when switching between the folded and unfolded states, the rotary damper damps the rotation of the legs relative to the bed halves, making the switching between the states slower and easier.

[0007] In this invention, The leg bodies are provided in pairs on each of the bed halves at an interval in the second rotation axis direction, At least two of the four legs are connected to the bed half via the rotary damper, The rotary damper may have a one-way clutch so that a braking force is applied in a first rotation direction when the bed half is opened, and no braking force is applied in a second rotation direction when the bed half is folded.

[0008] According to this configuration, in order to improve the operability of the folding bed, when two legs are connected to each bed half and a total of four legs support the two bed halves, if at least two or more legs are connected to the bed halves via rotary dampers, even if one rotary damper fails, braking force can be obtained from the remaining rotary dampers, thereby further improving operability.

[0009] In addition, by using a rotary damper with a one-way clutch so that a braking force is applied in a first rotation direction when the bed halves are opened and no braking force is applied in a second rotation direction when the bed halves are folded, a braking force is applied when the bed halves are about to open on their own due to their own weight, and conversely, when folding by lifting the connecting parts of the bed halves together as if against gravity, the braking force of the rotary damper is not applied, and the folding bed can be folded by lifting it smoothly.

[0010] Another aspect of the present invention is a folding bed. a pair of bed halves whose opposing ends are connected to each other so as to be rotatable about a first rotation axis extending horizontally; leg bodies provided on the bed halves so as to be rotatable about second rotation axes parallel to the first rotation axis; Equipped with The pair of bed halves are connected to the bed halves via rotary dampers that apply a brake to the rotational movement about the first rotation axis.

[0011] With this configuration, when switching between the folded and unfolded states, the rotation of the bed halves is damped by the rotary damper, which allows the folding bed of the present invention to switch states slowly and easily. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a folding bed according to the present invention will be described with reference to the drawings.

[0014] As shown in Figures 1 and 2, the folding bed 1 in this embodiment comprises a pair of bed halves 50, 60 whose opposing ends (proximal ends) are rotatably connected. The bed halves 50, 60 can be moved to select one of two states: a horizontally unfolded state in which the distal ends of the bed halves 50, 60 are widely separated as shown in Figure 1, and an inverted V-shaped folded state in which the distal ends of the bed halves 50, 60 are close together as shown in Figure 2. Figure 3 shows the folding bed 1 in the middle of being moved to switch states.

[0015] Figure 4 shows the structure of a typical folding bed. The mattress 10 is omitted from Figure 4. As shown in Figure 4, the folding bed 1 comprises a first leg 40, a first bed half 50, a second bed half 60, and a second leg 80. The first bed half 50 is shaped like a frame on which the mattress 10 is placed. The first leg 40 is connected to one end of the first bed half 50. The second bed half 60 is shaped like a frame on which the mattress 10 is placed, and is disposed adjacent to the first bed half 50. The second leg 80 is connected to the other end of the second bed half 60.

[0016] The first bed half 50 and the second bed half 60 are rotatably connected at their opposing ends (proximal ends) via a second pivot support 70. The first leg 40 is rotatably connected to one end of the first bed half 50 via a horizontally extending, shaft-shaped first pivot support 55 (an axis serving as a second rotation axis). The second leg 80 is rotatably connected to the other end of the second bed half 60 via a shaft-shaped third pivot support 90. The folding bed 1 includes a first link 78 that connects the first leg 40 and the second pivot support 70 to each other, and a second link 79 that connects the second leg 80 and the second pivot support 70 to each other.

[0017] The first bed half 50 and the second bed half 60 may be provided with a futon or tatami mat instead of the mattress 10. The mattress 10 is fixed to the frame of the first bed half 50 and the second bed half 60 with fasteners such as bolts. The mattress 10 may be removably fixed to the frame of the first bed half 50 and the second bed half 60 with a detachable structure (such as a hook-and-loop fastener or a detachable clip) not shown. In other words, the method of fixing the mattress 10 to each bed half 50, 60 may be either fixed or detachable.

[0018] The folding bed 1 has a structure in which the first bed half 50 and the second bed half 60 are arranged in that order, and is long in one direction. In this invention, the "bed longitudinal direction" refers to the direction parallel to the direction in which the first bed half 50 and the second bed half 60 are arranged (arrangement direction). In the following explanation, this will be referred to as the "bed longitudinal direction L" (see Figure 1). Furthermore, when the folding bed 1 is viewed from a planar direction, the direction perpendicular to the bed longitudinal direction L will be referred to as the "bed width direction W" (see Figure 4). Note that the folding bed of this invention does not necessarily have to be a vertically elongated, rectangular bed in a planar view; for example, the pair of bed halves may be configured to form an approximately square or approximately circular shape in a planar view.

[0019] In addition, in the first leg 40, first bed half 50, second bed half 60, second leg 80, etc., "one end" means the end in the direction of the "bed longitudinal direction L" that faces from the second bed half 60 toward the first bed half 50, and "the other end" means the end in the direction of the "bed longitudinal direction L" that faces from the first bed half 50 toward the second bed half 60.

[0020] Next, the first bed half 50 and the second bed half 60 will be described.

[0021] As shown in FIGS. 1 to 4, the first bed half 50 has a pair of vertical frames 51, 51 extending in the longitudinal direction L of the bed, and forms a frame on which the mattress 10 is placed.

[0022] As shown in Figure 4, the first bed half 50 is frame-shaped and consists of a pair of vertical frames 51, 51 extending along the bed longitudinal direction L and arranged parallel to each other, a horizontal frame 52 extending along the bed width direction W and connecting the pair of vertical frames 51, 51 to each other at one end 51a in the extension direction of the vertical frame 51, and two reinforcing frames 53, 53 arranged parallel to the horizontal frame 52 and connecting the pair of vertical frames 51, 51 to each other at the middle part of the vertical frame 51.

[0023] One end 51a of the vertical frame 51 is rounded and has a roughly arc shape. The vertical frame 51 and the horizontal frame 52 have a roughly U-shaped integral molded structure formed by bending a single pipe with an oval cross section. The first bed half 50 may have three or more vertical frames 51, and may also have reinforcing frames extending parallel to the vertical frames 51.

[0024] The second bed half 60 has a pair of vertical frames 61, 61 extending in the longitudinal direction L of the bed, and forms a frame on which the mattress 10 is placed.

[0025] Referring to Figure 4, the second bed half 60 is frame-shaped and includes a pair of vertical frames 61, 61 extending along the bed longitudinal direction L and arranged parallel to each other, a horizontal frame 62 extending along the bed width direction W and connecting the pair of vertical frames 61, 61 to each other at the other end 61b in the extension direction of the vertical frame 61, and two reinforcing frames 63, 63 arranged parallel to the horizontal frame 62 and connecting the pair of vertical frames 61, 61 to each other at the middle part of the vertical frame 61.

[0026] The other end 61b of the vertical frame 61 is rounded and has a roughly arc shape. The vertical frame 61 and the horizontal frame 62 have a roughly U-shaped integral molded structure formed by bending a single pipe with an oval cross section. The second bed half 60 may be equipped with three or more vertical frames 61, and may also be equipped with a reinforcing frame extending parallel to the vertical frame 61.

[0027] The second bed half 60 has a pair of leg mounting frames 64, 64 that are installed between a horizontal frame 62 and a reinforcing frame 63 adjacent to the horizontal frame 62 and extend along the longitudinal direction L of the bed.

[0028] Next, the first leg portion 40 will be described.

[0029] The first leg 40 is installed on the bed installation surface and supports the load on one end of the folding bed 1 in the bed longitudinal direction L. The first leg 40 comprises one leg body 43 rotatably connected to one side of the bed in the bed width direction W via a rotary damper 200, and the other leg body 43 rotatably connected to the opposite side of the bed width direction W via the rotary damper 200 at a distance from the one leg body 43. Each leg body 43 comprises a first foot sole 41 extending horizontally along the bed longitudinal direction L, and a second leg body 42 erected upward from the center of the first foot sole 41. A caster 100 is attached to the first foot sole 41.

[0030] The pair of left and right leg bodies 43, 43 are connected to each other via a rod-shaped connecting part 44 extending along the bed width direction W. The second leg body part 42 of one leg body 43 and the second leg body part 42 of the other leg body 43 are connected by a rod-shaped connecting part 44 positioned near the lower part of the second leg body parts 42 and extending along the bed width direction W. By fixing the pair of second leg body parts 42 by the connecting part 44 in this way, the first leg part 40 in which both leg bodies 43, 43 are integrated is configured.

[0031] One first foot sole portion 41 and the other first foot sole portion 41 are disposed parallel to each other, and one second leg body portion 42 and the other second leg body portion 42 are also disposed parallel to each other.

[0032] A plate-shaped support piece 45 is provided on the upper part of each second leg body portion 42 so as to extend in a direction away from the second bed half body 60. Each support piece 45 protrudes a predetermined length from one side edge of the second leg body portion 42 in the bed longitudinal direction L.

[0033] A first rotation support portion 55 (shaft serving as the second axis of rotation) is provided at the tip in the extension direction of the support piece 45 provided on each second leg body portion 42. The first rotation support portion 55 (shaft serving as the second axis of rotation) is a pin-shaped support shaft whose outer periphery is circular and extends a predetermined length. The first rotation support portion 55 (shaft serving as the second axis of rotation) is connected to a rotary damper 200 attached to one end portion 51a of each vertical frame 51 of the first bed half 50. The first rotation support portion 55 (shaft serving as the second axis of rotation) is supported by the rotary damper 200 on one end portion 51a of the vertical frame 51, so that one end portion of the first bed half 50 is rotatably supported with respect to the first leg portion 40.

[0034] The rotary damper 200 is equipped with a one-way clutch, and applies braking in the rotation direction (first rotation direction) when the folding bed 1 transitions from a folded state to an unfolded state. Conversely, in the rotation direction (second rotation direction) when the folding bed 1 transitions from an unfolded state to a folded state, the one-way clutch works to cause the pin-shaped first rotation support part 55 to spin freely, so that the braking force of the rotary damper 200 is not applied to the first rotation support part 55. In this embodiment, a disc damper manufactured by Fuji Latex Co., Ltd., which can obtain a relatively high braking torque, is used as the rotary damper 200.

[0035] A plate-shaped link connecting piece 47 is provided in the middle of the connecting portion 44 that connects the pair of second leg body portions 42, 42 and projects therefrom.

[0036] Next, a description will be given of the second rotation support portion 70. The second rotation support portion 70 supports one end of the second bed half 60 on the other end of the first bed half 50 so that the second bed half 60 can rotate.

[0037] 4, the second rotation support part 70 of this embodiment has a pillar-shaped part 71 extending along the bed width direction W, a pair of inner support pieces 72, 72 fixed to both ends of the pillar-shaped part 71, a pair of support shafts 73, 73 (shafts serving as first rotation axes) arranged at both ends of each inner support piece 72, and a pair of outer support pieces 74, 74 arranged outside the pair of inner support pieces 72, 72 via the pair of support shafts 73, 73 (shafts serving as first rotation axes). Covers 74a are attached to the outsides of the inner support piece 72 and the outer support piece 74 to protect both support pieces 72, 74.

[0038] 4, both end portions of the pair of inner support pieces 72, 72 are respectively arranged inside the other end portions 51b, 51b of the pair of vertical frames 51, 51 of the first bed half 50 and inside one end portion 61a, 61a of the pair of vertical frames 61, 61 of the second bed half 60. Both end portions of the pair of outer support pieces 74, 74 are respectively arranged outside the other end portions 51b, 51b of the pair of vertical frames 51, 51 of the first bed half 50 and outside one end portion 61a, 61a of the pair of vertical frames 61, 61 of the second bed half 60. The other end portion 51b of the vertical frame 51 and one end portion 61a of the vertical frame 61 are sandwiched between the inner support piece 72 and the outer support piece 74.

[0039] A specific pin-shaped support shaft 73 (the shaft that becomes the first rotation axis) having a circular outer periphery is inserted into one of the shaft support holes (not shown) of the inner support piece 72, the shaft support hole (not shown) of the other end 51b of the vertical frame 51, and one of the shaft support holes (not shown) of the outer support piece 74, respectively, and another pin-shaped support shaft 73 (the shaft that becomes the first rotation axis) having a circular outer periphery is inserted into the other shaft support hole (not shown) of the inner support piece 72, the shaft support hole of one end 61a of the vertical frame 61, and the other shaft support hole (not shown) of the outer support piece 74, respectively.

[0040] As a result, the second pivot support portion 70 rotatably supports the other ends 51b, 51b of the pair of vertical frames 51, 51 of the first bed half 50 relative to one ends 61a, 61a of the pair of vertical frames 61, 61 of the second bed half 60.

[0041] A pair of rod-shaped central legs 75, 75 are provided on the pillar-shaped portion 71 so as to hang down from both ends thereof. The pair of central legs 75, 75 are connected at their midpoint by a connecting portion 76. When the pair of central legs 75, 75 are moved via the second pivot support portion 70 in a direction in which one end of the first bed half 50 and the other end of the second bed half 60 are separated from each other, and the distal ends of the two bed halves 50, 60 are moved away from each other so that the folding bed 1 is in a horizontally unfolded state, the lower ends of the pair of central legs 75, 75 come into contact with the bed installation surface and support the load of the central portion of the folding bed 1 in the bed longitudinal direction L.

[0042] 4, a plate-shaped link connection piece 77 protrudes from the connecting portion 76 connecting the pair of central legs 75, 75, at a position corresponding to the link connection piece 47 of the connecting portion 44 of the first leg 40 in the bed width direction W. The other end of a rod-shaped first link 78 is rotatably connected to the link connection piece 77. One end of the first link 78 is rotatably connected to the link connection piece 47 of the connecting portion 44 of the first leg 40. The first leg 40 and the second rotation support portion 70 are connected to each other via the rotatably connected first link 78.

[0043] Next, we will explain the second leg 80. The second leg 80 is connected to the other end 61b of each vertical frame 61 of the second bed half 60, and supports the load on the other end side of the folding bed 1 in the bed longitudinal direction L.

[0044] The second leg portion 80 comprises a pair of left and right leg bodies 83, 83 arranged at an interval in the bed width direction W. Each leg body 83 has a first sole portion 81, 81 extending along the bed longitudinal direction L, and a second leg body portion 82, 82 erected so as to extend vertically upward from the center of each first sole portion 81.

[0045] The second leg body portions 82 are connected at their middle portions via rod-shaped connecting portions 84 extending along the bed width direction W. The pair of left and right leg bodies 83, 83 are connected to each other via the connecting portions 84, and the two leg bodies 83, 83 are integrated to form the second leg portion 80.

[0046] One first foot sole portion 81 and the other first foot sole portion 81 are disposed parallel to each other, and one second leg body portion 82 and the other second leg body portion 82 are also disposed parallel to each other.

[0047] Furthermore, a plate-shaped support piece 85 extends from the inside of the upper portion of each second leg body 82 toward the other end of the second bed half 60. Each support piece 85 protrudes a predetermined length from the other side edge of the second leg body 82 in the bed longitudinal direction L.

[0048] Furthermore, a third pivot support portion 90 is provided at the tip in the extension direction of the support piece 85 provided on each second leg body portion 82. In this embodiment, the third pivot support portion 90 is a pin-shaped support shaft with a circular outer periphery that extends a predetermined length and is inserted into a shaft support hole (not shown) formed in the leg mounting frame 64 of the second bed half 60.

[0049] A pair of second leg body portions 82 including support pieces 85 are positioned outside predetermined locations of a pair of leg mounting frames 64, 64 of the second bed half 60, and the third pivotal support portion 90 is inserted into and supported by an axial support hole (not shown) of the leg mounting frame 64, so that the other end side of the second bed half 60 is rotatably supported relative to the second leg portions 80.

[0050] 4, a plate-shaped link connection piece 87 protrudes from a predetermined position in the extension direction of the connecting portion 84. One end of a rod-shaped second link 79 in the extension direction is rotatably connected to the link connection piece 77 of the second rotation support portion 70, and the other end of the second link 79 in the extension direction is rotatably connected to the link connection piece 87 of the second leg portion 80, so that the second rotation support portion 70 and the second leg portion 80 are connected to each other via the second link 79.

[0051] A caster 100 is attached to the second leg 80 and can rotate in the folding direction and the unfolding direction when the folding bed 1 moves from the horizontal unfolded state in the folding direction in which one end of the first bed half 50 and the other end of the second bed half 60 move closer to each other, and when the folding bed 1 moves from the approximately inverted V-shaped folded state in the unfolding direction in which one end of the first bed half 50 and the other end of the second bed half 60 move away from each other.

[0052] The casters 100 are attached below the second leg body 82 of each leg body 83 of the second leg 80, at both ends of the first sole 81 in the extending direction.

[0053] The materials for the frame, first leg 40, second leg 80, etc. of the first bed half 50 and second bed half 60 that make up the folding bed 1 can be, for example, metal, plastic, or a combination of these materials.

[0054] [Other embodiments] The shapes, structures, layouts, etc. of each component constituting the folding bed in this invention, i.e., the first bed half, the second bed half, the first leg, the first pivoting support, the second pivoting support, the second leg, the casters, etc., are not limited to the above-mentioned embodiments.

[0055] For example, the first bed half and the second bed half may have an increased or decreased number of horizontal frames constituting each bed half, or may have a diagonal frame installed diagonally between a pair of vertical frames, as long as they are frame-shaped on which bedding can be placed.

[0056] In addition, although the present embodiment has been described as a folding bed that folds in two, the folding bed of the present invention is not limited to a folding bed that folds in two. For example, the present invention can be similarly applied to a bed that folds into three or more parts, such as a tri-fold bed.

[0057] Furthermore, in this embodiment, the rotary damper 200 is provided at two locations, namely, at the connection between the pair of second leg body portions 42, 42 of the first leg 40 and the vertical frame 51. However, the folding bed of the present invention is not limited to this. For example, the rotary damper 200 may be provided only at the connection between one of the second leg body portions 42 and the vertical frame 51. Conversely, the rotary damper 200 may be provided at three or more locations in total, by providing the rotary damper 200 at the connection between the pair of second leg body portions 42, 42 and the vertical frame 51, as well as at the connection between the pair of second leg body portions 82, 82 of the second leg 80 and the vertical frame 61. Furthermore, the rotary damper 200 may be provided on the vertical frames 51, 61 so as to connect to the support shaft 73 of the second rotation support portion 70. Even in this case, a rotary damper equipped with a one-way clutch may be used so that braking is applied in the first rotation direction but not in the second rotation direction.

[0058] Furthermore, in this embodiment, a rotary damper 200 equipped with a one-way clutch is used, but the folding bed 1 of the present invention may also use a rotary damper that does not have a one-way clutch. This also allows the folding bed 1 to be opened slowly by its own weight when opening from the folded state to the unfolded state, making the opening and closing operation easy.

[0059] In addition, in this embodiment, a disk damper manufactured by Fuji Latex Co., Ltd., which can obtain a relatively high braking torque, is used as the rotary damper, but the rotary damper of this invention may be other rotary dampers. The type of rotary damper can be selected appropriately depending on the load of the folding bed 1, etc.

[0060] Furthermore, a biasing member such as a tension coil spring may be installed between the first bed half and the second bed half, which biases the first bed half and the second bed half in a direction to rotate closer to each other via the second rotation support part.

[0061] Furthermore, the second leg body of each leg may be erected obliquely upward rather than perpendicular to the first sole. The first sole and second leg body of each leg may be connected to each other with a rod or rib to increase the rigidity, strength, and load-bearing capacity of the first sole and second leg body.

[0062] Furthermore, the first leg 40 and the second leg 80 in this embodiment have a pair of left and right leg bodies 43, 83 consisting of a first sole portion and a second leg body portion, but the first leg and / or second leg may further include a single or multiple leg bodies arranged between the pair of leg bodies to increase the load-bearing capacity of the first leg or second leg.

[0063] In addition, in this embodiment, two support shafts 73 serving as the first rotation axis are provided, thereby ensuring a gap between the second rotation support parts when folded. However, the present invention may also use a single shaft serving as the first rotation axis.

[0064] [Action and effect] Next, the effects of the folding bed 1 will be described.

[0065] When folding the folding bed 1 in the unfolded state as shown in Fig. 1, predetermined locations of the bed halves 50, 60 are grasped, and the bed halves 50, 60 are moved toward each other via the second pivot support part 70 in a direction in which one end of the first bed half 50 and the other end of the second bed half 60 move toward each other (see Fig. 3). Then, the second bed half 60 moves toward the first bed half 50 while sliding on the bed placement surface using the casters 100, and the folding bed 1 moves into a folded state in a substantially inverted V shape as shown in Fig. 2. At this time, the rotary damper 200 is in an idling state due to the action of the one-way clutch, allowing the folding bed 1 to be folded smoothly.

[0066] On the other hand, when unfolding the folding bed 1 from the folded state shown in FIG. 2 as shown in FIG. 1, for example, by grasping a predetermined position of the second bed half 60 and moving the distal ends of the two bed halves 50, 60 away from one end of the first bed half 50 and the other end of the second bed half 60 via the second pivot support part 70. Then, the second bed half 60 slides away from the first bed half 50 on the bed support surface using the casters 100, and the folding bed 1 moves to a horizontally unfolded state. At this time, the angle between the vertical frame 51 and the second leg body part 42 becomes smaller, but because this rotation is damped by the rotary damper 200, the folding bed 1 opens slowly under its own weight once it has opened to a certain extent. This allows the user to easily open and close the folding bed 1.

[0067] Furthermore, since the first leg portion 40 has a relatively simple configuration consisting of the first sole portion 41 and the second leg body portion 42, the manufacturability of the first leg portion 40 can be improved, reducing costs, and the strength and rigidity of the first leg portion 40 as a whole can be increased.

[0068] Furthermore, in this embodiment, the folding bed 1 further has second legs 80 connected to the other end 61b of each vertical frame 61 of the second bed half 60, and the second legs 80 have casters 100 attached thereto that rotate in the folding direction and the unfolding direction when the folding bed 1 moves from the horizontal unfolded state in a folding direction in which one end of the first bed half 50 and the other end of the second bed half 60 move closer to each other, and when the folding bed 1 moves from the approximately inverted V-shaped folded state in a unfolding direction in which one end of the first bed half 50 and the other end of the second bed half 60 move apart from each other.

[0069] Since the casters 100 are attached to the second leg 80, when the folding bed 1 is moved, the second bed half 60 can be easily moved closer to or further away from the first bed half 50, and the folding bed 1 can be moved smoothly with a light force.

[0070] The present invention is not limited to the above-described embodiment, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention. [Explanation of symbols]
