Description
Technical Field
[0001] The utility model relates to a chair, more particularly to a rocking chair. Background Art
[0002] Chairs are essential daily furniture for people to sit and rest, avoiding fatigue caused by lying or standing for a long time and reducing energy consumption from standing for a long time. Therefore, they are widely used in various places for users.
[0003] Chairs have a variety of structural designs. Most of the chairs in the prior art have fixed sitting angles and support forms. After sitting, the reclining angle cannot be changed, and the chair cannot be shaken or swung. Rocking chairs can rock back and forth. Common rocking chair structures usually have an arc-shaped seat plate at the bottom of an ordinary seat. When in use, the center of gravity of the user changes when lying down, which drives the arc-shaped seat plate to rock. However, this type of rocking chair has a single and fixed structure, and is large in size and weight, making it inconvenient to store or move and transport. Some foldable rocking chairs have complex linkage structures and high costs to achieve rocking when the user sits. In view of this, the designer specially designed a simple rocking chair, and this case was created. Utility Model Content

[0023] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0024] The utility model discloses a rocking chair, which comprises an upper component and a lower component, Figure 1 , Figure 2 The figure shows an embodiment of the utility model. The upper component may include a backrest rod 3 and a seat rod 4 movably mounted at both ends of an upper support part 1. The backrest rod 3 tilts backwards. An integral backrest cloth and a seat cloth (not shown in the figure) may be connected between the backrest rod and the seat rod. The lower component may include a plurality of foot rods 5 movably mounted at the bottom of a lower support part 2 that can be supported on the ground. In this embodiment, two sets of relatively supported foot rods 5 are provided. A rotatable pivot is formed between the upper support part 1 and the lower support part 2. At least one set of elastic components is provided between the upper support part 1 and the lower support part 2. The upper support part rotates backward when the backrest rod leans backward (such as Figure 2 As shown in the figure), the elastic component can be deformed when the upper support part rotates backward, and the resetting elastic component can drive the upper component to return to the initial position, thereby changing the sitting angle and achieving back and forth swinging when sitting.
[0025] Specifically, the upper support part 1 and the lower support part 2 can be parallel and separated at a distance in the initial position, and one end corresponding to the backrest rod is defined as the rear side B, and the end opposite to the backrest rod is defined as the front side A, the seat rod 4 is located at the front side, and the elastic component is installed at the front side or the rear side between the upper support part 1 and the lower support part 2. Two groups of elastic components are arranged between the upper support part and the lower support part, and the two groups of elastic components are symmetrically located on both sides between the upper support part and the lower support part, which can increase the elasticity and provide more stable force.
[0026] Combination Figures 1 to 6 As shown, in this embodiment, the upper assembly includes two upper cross bars 12 connected between two upper connecting blocks 11 to form an upper support portion 1, and the two sides of each upper connecting block 11 are respectively movably mounted with a seat rod 4 and a backrest rod 3. The lower assembly includes two lower cross bars 22 connected between two lower connecting blocks 21 to form a lower support portion 2, and the two sides of each lower connecting block 22 are respectively mounted with a foot rod 5. The rear end of the upper connecting block 11 is movably connected to a backrest rod 3 tilted backward, and the pivot point formed by the upper connecting block 11 and the lower connecting block 21 is located at the front end of the connection of the backrest rod 3. The two (the pivot point formed by the upper connecting block 11 and the lower connecting block 21 and the connection of the backrest rod 3) are not located on the same longitudinal axis, so that the backrest rod can drive the upper connecting block 11 to rotate when leaning back. The distance between the upper cross bar 12 and the lower cross bar 22 at the front side can be increased when the upper support part 1 rotates backward, and the distance between the upper cross bar 12 and the lower cross bar 22 at the rear side can be decreased when the upper support part rotates backward. Figure 5 , Figure 6 As shown, in this embodiment, the upper connecting block 11 and the lower connecting block 21 are respectively formed into triangular connecting blocks, and one of the top angle ends of the upper connecting block 11 and the lower connecting block 21 is defined as the middle connection, and the other two top angle ends are side connections. The upper connecting block 11 is connected above the lower connecting block 21, and the middle connection between the upper connecting block 11 and the lower connecting block 21 forms a pivot connection, the side connections of the upper connecting block 11 are respectively sleeved or plugged into the seat rod and the backrest rod, and the side connections of the lower connecting block are respectively sleeved or plugged into the foot rod (the backrest rod 3, the seat rod 4 and the foot rod 5 are plugged into the slots provided in the upper connecting block or the lower connecting block, and the inner ends of the backrest rod 3, the seat rod 4 and the foot rod 5 can also be connected with an elastic rope).
[0027] The elastic component can adopt a spring component. In the present embodiment, the elastic component is a front compression spring component, which includes an upper through hole and a lower through hole (not shown in the figure) respectively provided on the front sides of the upper support part 1 and the lower support part 2. In the present embodiment, an upper through hole is provided in the upper cross bar 12 located on the front side of the upper support part 1, and a lower through hole is provided in the lower cross bar 22 located on the front side of the lower support part 2. A screw rod 61 passes through the upper through hole and the lower through hole in sequence, and a compression spring 62 is installed in the lower section of the screw rod 61 located below the lower support part 2. The compression spring 61 can be sleeved on the lower section of the screw rod 61, and a stopper 63 is provided at the bottom of the screw rod 61 to stop the bottom of the compression spring 62. When the upper component rotates backward, it drives the upper support part 1 upward, and the distance between the upper through hole and the lower through hole (the distance between the upper cross bar 12 and the lower cross bar 22 on the front side becomes larger) increases and compresses the compression spring 62 downward. After the support part 1 rotates, the compressed compression spring 62 drives the upper component forward to return to the initial position when resetting, thereby realizing the rocking of the chair seat.
[0028] Furthermore, a buffer elastic member can be provided in the front side between the upper support part 1 and the lower support part 2 to reduce vibration when the upper component returns to the initial position. The buffer elastic member can be a spring, a rubber block or a sponge pad, or a buffer cylinder with a damping sense to achieve shock absorption and buffering. For example, a spring or elastic fast can be provided in the screw rod 61 for the part between the upper cross bar 12 and the lower cross bar 22 (between the upper through hole and the lower through hole) to achieve a buffering effect, reduce vibration, and increase comfort.
[0029] When the elastic component adopts a spring, it can also be in other forms. For example, the elastic component can be a tension spring, which can be installed on the front side between the upper support part and the lower support part. The tension spring is stretched when the upper support part rotates backward, and the stretched tension spring drives the upper component forward to return to the initial position when resetting. The elastic component can also be a compression spring, which is installed on the rear side between the upper support part and the lower support part. The compression spring is compressed when the upper support part rotates backward, and the compressed compression spring drives the upper component forward to return to the initial position when resetting. In addition to using a spring component, the elastic component as a telescopic structure can also be in the form of a cylinder, and the two ends of the cylinder are respectively connected to the front side or the rear side between the upper support part 1 and the lower support part 2. For example, the cylinder can be installed on the front side between the upper support part 1 and the lower support part 2. When the seated person sits on the rocking chair, the back leans back, the cylinder is stretched, and the seated person can also adjust the angle freely according to the comfort level. When the cylinder is fully stretched, it can be similar to a reclining chair. When it needs to be reset, the seated person leans forward and compresses the cylinder with his body weight, and the rocking chair gradually returns to the seat state of sitting.
[0030] When the utility model is used, the chair frame is assembled and unfolded. Figure 1In the state shown, the user can directly sit down on the chair fabric. When the user needs to change the sitting and lying angle and shake the chair frame, the user leans back with the center of gravity backward. The upper support part 1 rotates backward when the backrest rod 3 leans back (such as Figure 2 or Figure 4 As shown in the figure, the elastic component can be deformed when the upper support part rotates backward (for example, the compression spring 62 is compressed), and then the resetting elastic component can drive the upper component to return to the initial position, thereby changing the sitting angle, and the chair frame can swing back and forth when sitting, and so on, so as to realize the front and back swinging movement of the chair frame. When the chair frame needs to be folded, the chair cloth can be removed first, and then the backrest rod 3, the seat rod 4 and the foot rod 5 can be disassembled from the upper support part 1 and the lower support part 2 respectively, so that the packaging or storage volume of the chair frame can be greatly reduced, and it is also more convenient to carry.
[0031] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
