Description

The present invention relates to a rocking chair, and more particularly, to a rocking chair that is used by attaching seat fabric to an assembled or foldable seat frame.

2. Description of the Related Art Collapsible and foldable rocking chairs have been known for a long time. For example, Patent Document 1 discloses a chair in which a person sits while maintaining balance on two legs that are in contact with the ground (see especially FIG. 2). The chair disclosed here has two legs 18 on a frame 10 with a minimal structure (the reference numerals are the same as those in Patent Document 1), with unnecessary things removed in favor of lightweight and compactness when folded. It has a structure in which a fabric 50 for seating is attached.

By having only two legs as described above, it is possible to swing back and forth using the two legs as fulcrums, and as a result, it is possible to perform rocking.

However, while sitting, you must always use your legs to support the chair so that it does not fall over. In addition, there are cases where it is desired to use the backrest by tilting it in the direction that it will fall (reclining it), but there is a problem that if the backrest is tilted too far, there is a risk of falling and it will not be possible to fully relax.

Therefore, the present invention was made to solve these problems, and it is possible to maintain compactness, stand on its own without using your legs, and easily and safely take a reclining position. Their goal is to provide rocking chairs.

In order to solve the above problems, the present invention provides a rocking chair that is used by attaching seat fabric to an assembly type or folding type seat frame, and includes left and right rocking base legs that touch the ground and serve as fulcrums for rocking. , a center frame connecting the left and right rocking base legs, a seat pipe extending diagonally upward forward from each of the left and right rocking base legs, and a seat pipe extending diagonally backward from each of the left and right rocking base legs. The back pipe extending upward is connected from the middle of one of the seat pipes to the middle of the other seat pipe, and a " A front sub-frame extending in a U-shape or V-shape connects the middle of one of the back pipes to the middle of the other back pipe, and locks only when in a backward leaning posture. a rear sub-frame extending in a "U-shape" or "V-shape" toward the ground so that it can touch the ground together with the base legs; The feature is that it is attached by hooking the sheet fabric to the tip of the pipe.

With this configuration, the user can stand on his or her own without using his or her legs while maintaining compactness, and can easily and safely take a reclining position. That is, while it is possible to rock the chair back and forth using the two left and right rocking base legs as fulcrums, when the chair is in a forward leaning position, the front subframe touches the ground, allowing the chair to stand on its own. Furthermore, even when the chair is tilted backwards, the rear sub-frame touches the ground, allowing the chair to stand on its own in a reclining position, and also preventing it from falling backwards, allowing the chair to be used in a fully relaxed manner.

Further, when the front subframe is in contact with the ground, the lowest end portion of the seat fabric is located forward of the vertically above the grounding point of the rocking base leg, and when the rear subframe is in contact with the ground, It is preferable that the lowermost end portion of the seat fabric be located vertically above and rearward of the grounding point of the rocking base leg.

With this configuration, when in a forward leaning position, the entire center of gravity including the seated person is located forward of the vertically above the grounding point of the rocking base legs, and when in a backward leaning position, the entire center of gravity including the seated person is located in front of the ground point of the rocking base leg. It is located at the rear of the vertically above the grounding point of the rocking base leg, making it easy to maintain the forward leaning posture and the successor posture.

Further, in a free state before seating on a horizontal plane, it is desirable to adjust the overall weight balance so that the rear subframe is in contact with the ground and the front subframe is lifted off the ground.

With this configuration, even if it is a lightweight chair with a high back (the backrest surface extends to the level of the head) for comfortable sitting, the overall height of the chair in the free state can be suppressed, and the height of the chair can be reduced by the wind. It can reduce the possibility of falling or being blown away.

By applying the present invention, it is possible to provide a rocking chair that maintains compactness, can stand on its own without using its own legs, and can easily and safely take a reclining position.

Hereinafter, a rocking chair 100 that is an example of an embodiment of the present invention will be described with reference to the accompanying drawings. It should be noted that in order to make the drawings easier to understand, the sizes and dimensions of each part are exaggerated in some parts, and some parts may not necessarily match the actual product. In addition, each drawing should be viewed in the direction of the symbol, and based on the direction, it will be expressed as top, bottom, left, right, front, and back.

<Rocking chair configuration>
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 serves as the frame of the chair.

The seat fabric 110 is formed by sewing cloth or the like so that a seat surface 111, a backrest surface 112, and further a side surface 113 are connected in a continuous manner so as to wrap around the body of a seated person. A headrest 114 is provided above the backrest surface 112. Further, insertion portions 116 and 118 for inserting pipes are provided on the left and right fronts of the back of the seat surface 111 and on the left and right sides of the headrest 114.

The seat frame 120 is made up of hollow pipe-shaped members and various joints that connect these pipes, and can be compactly stored and transported by taking them apart or folding them.

The seat frame 120 includes left and right rocking base legs 122a and 122b that touch the ground and serve as rocking fulcrums, and two rocking base legs 122a and 122b that are inserted into the left and right rocking base legs 122a and 122b to connect the rocking base legs 122 to each other. It is constructed based on a center frame 124 of. In addition, in the drawings, the same numerals with suffixes a and b indicate each of the left and right pairs of parts individually.

A seat pipe 126a extending diagonally upward to the front and a back pipe 128a extending diagonally upward to the rear are inserted into one of the locking base legs 122a. In addition, in this embodiment, the back pipe 128a is configured to be able to be disassembled into two parts.

A seat pipe 126b extending diagonally upward in the front and a back pipe 128b extending diagonally upward rearward are inserted into the other locking base leg 122b. In addition, in this embodiment, the back pipe 128b is configured to be able to be disassembled into two parts.

Front subframe joint parts 127a and 127b each having a plug-in branch toward the ground are attached near the tips of the two seat pipes 126a and 126b. A front subframe 130 (see FIG. 4(a)), which has a substantially U-shape when viewed from the front, is inserted into the front subframe joint parts 127a and 127b. This front sub-frame 130 includes one central pipe 131, substantially L-shaped L-shaped joints 132a and 132b inserted on the left and right sides of the central pipe 131, and side pipes 133a connected via these L-shaped joints 132a and 132b. 133b. Note that the front subframe 130 is configured to be foldable as shown in FIG. 4(b).

By inserting the front subframe 130 having such a configuration into the front subframe joint parts 127a and 127b (the insertion branch thereof), it is possible to connect the middle of one seat pipe 126a to the middle of the other seat pipe 126b. , is configured to extend (protrude) toward the ground in a "U-shape". Further, the front sub-frame 130 has a length that allows it to touch the ground together with the rocking base legs 122 only when the rocking chair 100 is in a forward leaning position (see FIG. 5). Note that the "U-shape" is not an essential configuration, and other shapes such as "V-shape," "U-shape," and "W-shape" may also be used.

Furthermore, rear subframe joint parts 129a and 129b each having a plug-in branch toward the ground are attached to the middle of the two rear pipes 128a and 128b. A rear subframe 140, which is substantially U-shaped when viewed from the front, is inserted into the rear subframe joint parts 129a and 129b. Note that the rear subframe 140 has substantially the same configuration as the front subframe 130 described above, except for its size, and therefore detailed description thereof will be omitted.

By inserting the rear subframe 140 having such a configuration into the rear subframe joint parts 129a and 129b (the insertion branch thereof), you can connect the middle of one back pipe 128a to the middle of the other back pipe 128b, and also It is configured to extend (protrude) toward the side in a "U-shape". Further, the rear subframe 140 has a length that allows it to touch the ground together with the rocking base legs 122 only when the rocking chair 100 is in a backward leaning position (see FIG. 6). Note that the "U-shape" is not an essential configuration for the rear subframe 140 as well, and other shapes such as "V-shape," "U-shape," and "W-shape" may also be used.

Finally, the rocking chair 100 is completed by hooking (inserting) the insertion parts 116 and 118 of the seat fabric 110 onto the tips of the seat pipe 126 and the back pipe 128.

In addition, in a free state before sitting on a horizontal plane, the weight 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 lifted off the ground, that is, maintains a "backwards leaning posture". The balance has been adjusted.

〈Operations and functions of rocking chair〉
Although the rocking chair 100 is configured as described above, the center of gravity position G of the seated person 10 is important when actually using it.

When seated, the rocking chair 100 is initially in a "forward leaning position" with the front subframe 130 and the rocking base legs 122 touching the ground, as shown in FIG. The rear subframe 140 is in a floating state from the ground. At this time, the center of gravity position G is located forward of the vertically above the grounding point GP of the rocking base leg 122, and the forward leaning posture can be stably maintained. This is because the shape of the seat fabric 110 is configured such that when the front subframe 130 is in contact with the ground, the lowest end portion LP of the seat fabric 110 is located forward of the vertically above the grounding point GP of the rocking base leg 122. This is due to the configuration.

When the seated person 10 moves the entire rocking chair 100 in the direction of lifting the front subframe 130 using his or her legs, that is, in the direction of reclining, neither the front subframe 130 nor the rear subframe 140 is in contact with the ground. , only the rocking base legs 122 are in contact with the ground (see FIG. 8). At this time, the center of gravity position G is located near the vertically above the grounding point GP of the rocking base leg 122, so it is possible to enjoy swinging in the front and rear direction without requiring a large force. Note that the state between the forward leaning posture and the backward leaning posture described below is a "rocking state" where you can enjoy shaking.

Further, when the entire rocking chair 100 is tilted backward (in the reclining direction), the center of gravity G moves backward beyond the vertically above the grounding point GP of the rocking base leg 122. However, since the rocking chair 100 according to the present invention includes the rear subframe 140, it does not fall backwards, and the rocking chair 100 according to the present invention does not fall backwards, but instead assumes a "backward leaning posture" in which the rear subframe 140 and the rocking base legs 122 are in contact with the ground. Become fixed and maintained. At this time, the center of gravity G has moved backward beyond the vertically above the grounding point GP of the rocking base leg 122, so that a stable backward leaning posture can be maintained. This is done so that when the rear subframe 140 is in contact with the ground, the lowermost part LP of the seat fabric 110 is positioned vertically above and behind the grounding point GP of the rocking base leg 122. This is due to the configuration of the shape.

In addition, it is preferable to adjust the shape of the seat material 110 so that the center of gravity position G is not too far back from vertically above the grounding point GP of the rocking base leg 122 when the seat is tilted backward. If it is moved too far backward, a large amount of force or a change in posture will be required to return from the backward leaning position to the rocking position, making it difficult to use.

When in use, it is designed to balance the center of gravity between the front and back, allowing you to stably maintain a normal position (leaning forward) that is perfect for tasks such as tending a fire, cooking, watching sports, reading, etc. . Furthermore, a relaxed position (backward leaning posture) can be stably maintained when taking a break or taking a nap. Furthermore, it is also possible to take a rocking position (rocking state) in which the user can enjoy a state of swinging back and forth between a forward-leaning posture and a backward-leaning posture.

As described above, the present invention provides a rocking chair 100 that is used by attaching a seat fabric 110 to an assembled or foldable seat frame 120, and includes left and right rocking bases that touch the ground and serve as rocking fulcrums. A center frame 124 that connects the legs 122, the left and right rocking base legs 122, a seat pipe 126 extending obliquely forward and upward from each of the left and right rocking base legs 122, and a A back pipe 128 extending rearward and diagonally upward from each is connected from the middle of one seat pipe 126a to the middle of the other seat pipe 126b, so that it can touch the ground together with the rocking base legs 122 only when in a forward leaning posture. The front subframe 130 is formed to extend in a "U-shape" or "V-shape" toward the ground, and connects the middle of one back pipe 128a to the middle of the other back pipe 128b, A rear subframe 140 is formed to extend toward the ground side in a "U-shape" or "V-shape" so that it can touch the ground together with the rocking base legs 122 only when in a backward leaning posture, It is characterized in that the seat fabric 110 is hooked and attached to the tips of the seat pipe 126 and the back pipe 128.

With this configuration, the user can stand on his or her own without using his or her legs while maintaining compactness, and can easily and safely take a reclining position. That is, while it is possible to rock the chair back and forth using the two left and right rocking base legs 122 as fulcrums, the front sub-frame 130 is in contact with the ground in the forward leaning position, allowing the chair to stand on its own. Furthermore, even when the chair is tilted backward, the rear sub-frame 140 touches the ground, allowing it to stand on its own in a reclined position, and also prevent it from falling backwards, allowing the chair to be used in a fully relaxed manner.
