Description

[Technical Field]

[0001] The present invention relates to a rocking chair, and more particularly to a rocking chair in which a seat fabric is attached to an assembly-type or foldable seat frame. [Background technology]

[0002] Collapsible or foldable rocking chairs have been known for some time. For example, Patent Document 1 discloses a chair that is balanced on two legs that touch the ground when sitting (see FIG. 2 in particular). The chair disclosed therein is configured with a minimal frame 10 (the same reference numerals as in Patent Document 1) that has been stripped of unnecessary parts in order to prioritize lightweight and compactness when folded, with two legs 18 attached, and a seating fabric 50 attached. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] US102012312 Summary of the Invention [Problem to be solved by the invention]

[0004] By using only two legs as described above, it is possible to swing the robot back and forth using those two legs as fulcrums, which results in a rocking motion.

[0005] However, while sitting, you must always use your feet to support the chair so that it does not tip over. Also, while there are times when you want to use the chair with the back tilted (reclined), there is a problem that if you tilt it too far, you may fall over and not be able to fully relax.

[0006] The present invention has been made to solve these problems, and its object is to provide a rocking chair that can stand on its own without using its legs while maintaining compactness, and can easily and safely assume a reclining position. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a rocking chair that is used by attaching a seat fabric to an assembly-type or foldable seat frame, and that includes left and right rocking base legs that contact the ground and serve as rocking fulcrums, a center frame that connects the left and right rocking base legs, seat pipes that extend obliquely upward and forward from each of the left and right rocking base legs, a back pipe that extends obliquely upward and rearward from each of the left and right rocking base legs, and a seat pipe that extends from the middle of one of the seat pipes to the middle of the other of the seat pipes. and a front subframe that connects the back pipes and extends in a U-shape or V-shape toward the ground so that it can contact the ground together with the rocking base leg only when the vehicle is in a forward-leaning position; and a rear subframe that connects the middle of one back pipe to the middle of the other back pipe and extends in a U-shape or V-shape toward the ground so that it can contact the ground together with the rocking base leg only when the vehicle is in a backward-leaning position, and the seat fabric is attached by hooking it onto the ends of the seat pipes and the back pipes.

[0008] This configuration allows the chair to remain compact, stand on its own without using its own legs, and easily and safely assume a reclining position. In other words, while the chair can be rocked back and forth using the two left and right rocking base legs as fulcrums, the front subframe contacts the ground when tilted forward, allowing the chair to stand on its own. Furthermore, when tilted backward, the rear subframe contacts the ground, allowing the chair to remain standing in the reclined position and preventing it from tipping over backward, allowing the chair to be used in a fully relaxed manner.

[0009] Furthermore, it is desirable that when the front subframe is in contact with the ground, the lowest end portion of the seat fabric be located forward of and vertically above the contact point of the rocking base leg, and when the rear subframe is in contact with the ground, the lowest end portion of the seat fabric be located vertically above and rearward of the contact point of the rocking base leg.

[0010] With this configuration, when the chair is in a forward-leaning position, the center of gravity of the entire chair, including the occupant, is located vertically above the ground contact point of the rocking base leg and forward-leaning when the chair is in a backward-leaning position, making it easier to maintain the forward-leaning position and the subsequent position.

[0011] In addition, it is desirable to adjust the overall weight balance so that, in a free state before being seated on a horizontal plane, the rear subframe is in contact with the ground and the front subframe is lifted off the ground.

[0012] By configuring it in this way, even if the chair is a lightweight high-back type (the backrest extends down to head position) that allows for comfortable sitting, the overall height of the chair in its free state can be reduced, reducing the possibility of the chair tipping over or being blown away by the wind. [Effects of the Invention]

[0013] By applying the present invention, it is possible to provide a rocking chair that can stand on its own without using its legs while maintaining its compactness and can easily and safely assume a reclining position. [Brief explanation of the drawings]

[0015] Below, a rocking chair 100, which is an example of an embodiment of the present invention, will be described with reference to the accompanying drawings. Please note that in order to make the drawings easier to understand, the size and dimensions of various parts are exaggerated and may not necessarily match the actual product. Furthermore, each drawing should be viewed in accordance with the direction of the reference numerals, and the directions are expressed as up, down, left, right, front, and back based on these directions.

[0016] <Configuration of a rocking chair> A rocking chair 100 shown as an example of an embodiment of the present invention has a structure in which a seat fabric 110 is attached to a seat frame 120 that forms the skeleton of the chair.

[0017] The seat fabric 110 is configured in a shape that envelops the body of a seated person by sewing cloth or the like so that the seat surface 111, backrest surface 112, and even side surfaces 113 are connected in a continuous manner. A headrest 114 is provided above the backrest surface 112. In addition, insertion portions 116, 118 for inserting pipes are provided on the left and right front sides of the back of the seat surface 111 and on the left and right sides of the headrest 114.

[0018] The seat frame 120 is made up of hollow pipe-shaped members and various joints that connect these pipes, and can be disassembled or folded up to make it compact for storage and transportation.

[0019] The seat frame 120 is constructed based on left and right rocking base legs 122a, 122b that contact the ground and serve as rocking fulcrums, and two center frames 124 that are inserted into the left and right rocking base legs 122a, 122b and connect the rocking base legs 122. In the drawings, the same numbers with the letters a and b suffixed indicate the individual parts of the left and right pair.

[0020] A seat pipe 126a extending obliquely upward and forward and a back pipe 128a extending obliquely upward and rearward are inserted into one of the rocking base legs 122a. In this embodiment, the back pipe 128a is configured to be disassembled into two parts.

[0021] A seat pipe 126b extending obliquely upward and forward and a back pipe 128b extending obliquely upward and rearward are inserted into the other rocking base leg 122b. In this embodiment, the back pipe 128b is configured to be disassembled into two parts.

[0022] Front subframe joint parts 127a, 127b, each with a branched insertion portion facing the ground, are attached near the ends of the two seat surface pipes 126a, 126b. A front subframe 130 (see FIG. 4(a)), which is configured to be roughly U-shaped when viewed from the front, is inserted into these front subframe joint parts 127a, 127b. This front subframe 130 is made up of a single central pipe 131, two roughly L-shaped L-joints 132a, 132b inserted into the left and right sides of the central pipe 131, and side pipes 133a, 133b connected via these L-joints 132a, 132b. The front subframe 130 is configured to be foldable, as shown in FIG. 4(b).

[0023] The front subframe 130 configured as described above is inserted into the front subframe joint parts 127a, 127b (insertion branches) to connect the middle of one seat pipe 126a to the middle of the other seat pipe 126b, and is configured to extend (protrude) in a U-shape toward the ground. The front subframe 130 is long enough to contact the ground together with the rocking base leg 122 only when the rocking chair 100 is in a forward-leaning position (see FIG. 5). The U-shape is not a required configuration, and other shapes such as a V-shape, a U-shape, or a W-shape may also be used.

[0024] Additionally, rear subframe joint parts 129a, 129b, each with an insertion branch facing the ground, are attached midway along the two rear pipes 128a, 128b. A rear subframe 140, which is configured to be roughly U-shaped when viewed from the front, is inserted into these rear subframe joint parts 129a, 129b. Note that the rear subframe 140 has roughly the same configuration as the front subframe 130 described above, except for its size, so a detailed description will be omitted.

[0025] The rear subframe 140 configured as described above is inserted into the rear subframe joint parts 129a, 129b (insertion branches) to connect the middle of one rear pipe 128a to the middle of the other rear pipe 128b, and is configured to extend (protrude) in a U-shape toward the ground. The rear subframe 140 is long enough to be in contact with the ground together with the rocking base leg 122 only when the rocking chair 100 is in a rearward tilting position (see FIG. 6). The U-shape is not a required configuration for the rear subframe 140, and other shapes such as a V-shape, a U-shape, or a W-shape may also be used.

[0026] Finally, the inserting portions 116, 118 of the seat fabric 110 are hooked (inserted) onto the ends of the seat pipe 126 and the back pipe 128, respectively, and the rocking chair 100 is completed.

[0027] In addition, in the free state before sitting on a horizontal surface, the weight balance of the entire rocking chair 100 is adjusted so that the rear subframe 140 is in contact with the ground and the front subframe 130 is raised above the ground, i.e., so as to maintain a "backward leaning posture."

[0028] <The function of a rocking chair> When the rocking chair 100 is actually used as configured above, the center of gravity G of the seated person 10 becomes important.

[0029] When a user sits down, the rocking chair 100 is initially in a "forward-leaning position" with the front subframe 130 and the rocking base leg 122 in contact with the ground, as shown in Figure 7. The rear subframe 140 is lifted off the ground. At this time, the center of gravity G is located forward of the point vertically above the ground contact point GP of the rocking base leg 122, allowing the user to maintain a stable forward-leaning position. This is because the shape of the seat fabric 110 is configured so that the lowest end portion LP of the seat fabric 110 is located forward of the point vertically above the ground contact point GP of the rocking base leg 122 when the front subframe 130 is in contact with the ground.

[0030] When the occupant 10 uses his / her legs to lift the front subframe 130, i.e., to move the entire rocking chair 100 in the reclining direction, neither the front subframe 130 nor the rear subframe 140 touches the ground, and only the rocking base leg 122 touches the ground (see Figure 8). At this time, the center of gravity G is located near the vertically upper position of the contact point GP of the rocking base leg 122, so it is possible to enjoy rocking in the front-to-back direction without requiring much force. The state between the forward leaning position and the backward leaning position described below is the "rocking state," in which rocking can be enjoyed.

[0031] Furthermore, when the entire rocking chair 100 is tilted backward (reclining direction), the center of gravity G moves rearward beyond the vertical position above the ground contact point GP of the rocking base leg 122. However, because the rocking chair 100 according to the present invention has the rear subframe 140, it does not tip backward and is maintained and fixed in a "rearward tilted position" in which the rear subframe 140 and the rocking base leg 122 are in contact with the ground. At this time, since the center of gravity G moves rearward beyond the vertical position above the ground contact point GP of the rocking base leg 122, a stable rearward tilted position can be maintained. This is due to the shape of the seat fabric 110 being configured so that the lowest end portion LP of the seat fabric 110 is located vertically above and rearward of the ground contact point GP of the rocking base leg 122 when the rear subframe 140 is in contact with the ground.

[0032] It is preferable to adjust the shape of the seat fabric 110 so that, when the seat is in a rearward tilted position, the center of gravity G is not positioned too far rearward from the point vertically above the ground contact point GP of the rocking base leg 122. If it is positioned too far rearward, a large force or change in position is required to return the seat from the rearward tilted position to the rocking state, making it difficult to use.

[0033] Because the chair is designed to have such a balanced front-to-back center of gravity, it can be used to maintain a stable, normal position (forward leaning posture) that is perfect for activities like tending a fire, cooking, watching sports, or reading. It can also be used to maintain a relaxed position (backward leaning posture) for resting or napping. It can also be used in a rocking position (rocking state), which allows you to enjoy the swaying motion between the forward and backward leaning postures.

[0034] As described above, the present invention provides a rocking chair 100 in which a seat fabric 110 is attached to an assembly-type or foldable seat frame 120, and the rocking chair 100 includes left and right rocking base legs 122 that contact the ground and serve as fulcrums for rocking, a center frame 124 that connects the left and right rocking base legs 122, seat pipes 126 that extend obliquely upward and forward from each of the left and right rocking base legs 122, back pipes 128 that extend obliquely upward and rearward from each of the left and right rocking base legs 122, and a seat pipe 126a that connects midway between one seat pipe 126a and the other seat pipe 126b. and a front subframe 130 extending in a U-shape or V-shape toward the ground so that it can contact the ground together with the rocking base leg 122 only when the vehicle is in a forward-leaning position; and a rear subframe 140 connecting the middle of one back pipe 128a to the middle of the other back pipe 128b and extending in a U-shape or V-shape toward the ground so that it can contact the ground together with the rocking base leg 122 only when the vehicle is in a backward-leaning position. The seat fabric 110 is attached by hooking it onto the ends of the seat pipe 126 and the back pipe 128.

[0035] This configuration allows the chair to remain compact, stand on its own without using its own legs, and easily and safely assume a reclining position. That is, while the chair can be rocked back and forth using the two left and right rocking base legs 122 as fulcrums, the front subframe 130 contacts the ground when tilted forward, allowing the chair to stand on its own. Furthermore, when tilted backward, the rear subframe 140 contacts the ground, allowing the chair to stand on its own in a reclining position and preventing it from tipping backward, allowing the chair to be used in a fully relaxed manner.
