Description

Technical Field

[0004] , ,

[0001] The present invention relates to the technical field of folding rocking chairs, and more specifically, to portable rocking chairs.

Background Art

[0002] Existing portable rocking chairs usually use folding or assembled metal rods as the chair body, and a chair cloth is connected to the upper end to form a seating surface. Such a design of rocking chair is mostly based on the idea of conventional rocking chairs, that is, the rocking effect is realized by the rocking of the entire chair cloth or the entire chair body. Generally, there are mainly the following two types of technical solutions. In the first technical solution, the chair body structure is relatively fixed, and the chair cloth is suspended on the vertical rods on both sides of the body. When a user sits, the chair cloth swings back and forth relative to the chair body as a whole, thereby generating a rocking feeling. In the second technical solution, the whole chair is divided into two upper and lower parts. The upper part functions as a rocking unit to support the chair cloth, the lower part is fixed to the ground, and the upper and lower parts rock back and forth through a connection structure.

[0003] However, all of the above existing portable rocking chairs rely on the back-and-forth rocking of the entire chair cloth to generate a rocking effect. In such a structure, there is no stable fixed support point during use, so users often feel a great sense of uneasiness. In particular, when the feet are in the air with the rocking of the chair cloth, users are likely to associate with the possibility of losing body balance or falling because they do not contact the ground or fixed members and are not supported, thereby lacking a sense of security in the experience.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The purpose of this invention is to provide a portable rocking chair that can improve safety and stability while maintaining the rocking experience, in order to overcome the shortcomings of existing portable rocking chairs, which rely on the back-and-forth rocking of the entire chair fabric, and thus do not provide stable support to the user, and tend to cause feelings of insecurity with the feet dangling in the air. [Means for solving the problem]

[0005] The technical solution employed by this invention is as follows: A portable rocking chair is provided, which includes an upper support seat and a lower support seat that are movably connected to each other and whose positions are restricted, a rear support rod connected to the upper support seat, a rear support leg connected to the lower support seat, a front support rod located in front of the rear support rod, the upper ends of the front support rod and the rear support rod are jointly connected to the chair fabric, the chair fabric having a seat area and a backrest area for supporting the buttocks and back of the human body respectively, the front support leg located in front of the rear support leg, and when the rocking chair is unfolded, the front support leg, rear support leg and front support rod maintain a fixed position relative to the ground, the rear support rod swings back and forth in response to the movement of the upper support seat relative to the lower support seat, thereby tilting the backrest area of ​​the chair fabric forward or rocking it backward.

[0006] By employing the above technical solution, this invention avoids the reliance on the forward and backward rocking of the entire chair fabric as in the prior art, by setting a movable connection between the upper and lower support seats and driving the backrest area of ​​the chair fabric with the rear support rod to achieve forward and backward rocking. The front and rear support legs cooperate to form a stable support, and the front support rod is always fixed and maintained in contact with the ground during use, so the user can obtain a secure support point when sitting on the chair fabric and does not experience the anxiety caused by their feet floating in the air. Furthermore, because the front support rod is fixed and does not swing back and forth with the rear support rod, the front edge position of the chair fabric is fixed so that it does not move, and the front edge of the chair fabric can stably support the inside of the user's thighs. As a result, when the body tilts forward or rocks backward, the position of the contact point felt by the thighs does not change, and a greater sense of stability and security is obtained psychologically.

[0007] According to one embodiment of the present invention, an elastic member is positioned and mounted between the upper support seat and the lower support seat. When the upper support seat swings relative to the lower support seat, the elastic member deforms and provides a restorative force to the swing. This design makes the rocking process smoother, allowing the user to experience a natural reciprocating motion during use. After the application of force is stopped, it can automatically return to its initial position, improving the convenience and safety of operation.

[0008] According to one embodiment of the present invention, the structure further includes a connecting rod that is connected to a lower support seat and forms a horizontally positioned frame. This structure contributes to improving the overall stability of the rocking chair, making the front and rear support legs less prone to deformation or displacement during rocking, thereby improving the overall load-bearing capacity and service life.

[0009] According to one embodiment of the present invention, the connecting rod includes a vertical connecting rod, one end of which is movably connected to a lower support seat, and the other end of which is provided with a connecting seat for connecting the front support leg and / or the front support rod. This design allows the front support leg and the front support rod to form a stable support point, while the connecting seat ensures secure fixation, thereby improving the stability of the rocking chair under various load conditions.

[0010] According to one embodiment of the present invention, the connecting rod further includes a lateral connecting rod for connecting two of the connecting seats. This structure gives the rocking chair better lateral integrity, avoids swaying due to load on one side, and thereby improves overall structural strength and safety.

[0011] According to one embodiment of the present invention, the connecting seat has a second insertion groove into which, when folded, the front support rod and / or front support leg are inserted and positioned in the front-to-back direction. This design significantly simplifies the folding and storage operation of the rocking chair, reduces the space occupied, makes it easier to carry and store, and improves portability.

[0012] According to one embodiment of the present invention, the lower support seat has a first insertion groove into which, in a folded state, a rear support rod and / or rear support leg are inserted and positioned in the front-rear direction.

[0013] According to this proposed technology, the rocking chair can maintain a compact, neatly aligned state after being folded, preventing parts from scattering and improving the orderliness of storage and the convenience of transport.

[0014] According to one embodiment of the present invention, a snap hook is installed inside the rear support leg, and the snap hook engages with the lower support seat. This design enables quick positioning and stable connection when the rocking chair is extended, prevents the support leg from accidentally detaching during use, and thereby improves safety and reliability.

[0015] According to one embodiment of the present invention, the upper or lower support seat is provided with a first position restricting mechanism for triggering position restriction when it moves to one end of the stroke. This structure effectively controls the range of motion, preventing excessive oscillation of the upper support seat from causing discomfort to the user or damaging the structure, thereby ensuring safe use.

[0016] According to one embodiment of the present invention, the upper or lower support seat is provided with a second position restrictor for triggering position restriction when it moves to the other end of the stroke. This design, in cooperation with the first position restrictor, enables effective position restriction at both ends, ensuring stability and controllability of the oscillating process, and further improving safety and durability.

[0017] According to one embodiment of the present invention, after the rocking chair is unfolded, the upper support seat has an initial state in which it is in any position between forward tilt and rearward rocking relative to the lower support seat. When a user sits down, the chair fabric transmits the user's weight to the upper support seat and moves it from its initial position in the forward tilt direction, thereby creating a cushioning effect and improving the comfort and safety of the user.

[0018] According to one embodiment of the present invention, after the rocking chair is unfolded, the upper support seat has an initial state in which it is in a forward-tilted position or a rearward-rocking position relative to the lower support seat. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described in detail. Examples of the embodiments are shown in the drawings. In the drawings, the same or similar reference numerals represent the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are used only for interpreting the present invention and cannot be construed as limiting the present invention.

[0021] Embodiment 1 As shown in Figures 1 to 11, this embodiment discloses a portable rocking chair including an upper support seat 1 and a lower support seat 2 that are mutually position-restricted and movably connected via a pivot axis 3. A rear support rod 6 is connected to the upper end of the upper support seat 1, and a rear support leg 5 is connected to the lower end of the lower support seat 2. A front support rod 9 is positioned in front of the rear support rod 6, and the upper ends of the front support rod 9 and the rear support rod 6 are jointly connected to a chair fabric (not shown), which as a whole includes a seat area and a backrest area for supporting the buttocks and back of a human body, respectively. A front support leg 8 is located in front of the rear support leg 5.

[0022] When the rocking chair is unfolded, the front support legs 8, rear support legs 5, and front support rod 9 maintain a fixed position relative to the ground, while the rear support rod 6 rocks back and forth in response to the upper support seat 1 swinging relative to the lower support seat 2. This causes the backrest area of ​​the chair fabric to tilt forward or rock backward, thereby realizing the rocking function.

[0023] Furthermore, as shown in Figure 3, the upper support seat 1 includes the seat body 11, and a first connecting portion 12 is provided at an inclination at the upper end of the seat body 11. The first connecting portion 12 has a slot structure, into which the lower end of the rear support rod 6 is inserted, achieving a secure and removable fit. The rear support rod 6 is responsible for supporting the backrest, and its length is designed to be longer than the length of the front support rod 9, so that the backrest area is higher than the seat area. A first pivot seat 14 and a grooved first spring seat 13 are provided protruding from the lower end of the seat body 11, and a first position restricting portion 15 for limiting the swing stroke is integrally provided on the rear side of the first pivot seat 14.

[0024] Furthermore, as shown in Figure 4, a second connecting portion 21 is provided at the lower end of the lower support seat 2, which has a slot structure and is inserted and fitted with the upper end of the rear support leg 5, ensuring stable support of the rear support leg 5. A hinge groove 22 is provided on the front side of the lower support seat 2, and one end of the vertical connecting rod 71 is inserted into the hinge groove 22 and hinged to the lower support seat 2. A first insertion groove 23 is opened along the front-rear direction in the lower support seat 2 for inserting the rear support rod 6 and / or rear support leg 5 in a folded state and positioning them in the front-rear direction. A second spring seat 25 and a second axle seat 24 are provided at the upper end of the lower support seat 2, and the second axle seat 24 cooperates with the first axle seat 14 of the upper support seat 1 to jointly form the mounting position of the rotation axis 3, allowing the upper support seat 1 to rotate around the rotation axis 3 relative to the lower support seat 2.

[0025] Furthermore, as shown in Figure 8, in the unfolded state, the two vertical connecting rods 71, one horizontal connecting rod 72, and the lower support seat 2 jointly form a roughly triangular frame structure, which is horizontally positioned, significantly improving overall stability. In the folded state, the vertical connecting rods 71 ​​can be folded simultaneously, making it foldable and easy to store.

[0026] Specifically, as shown in Figure 9, the connecting seat 10 is provided with a third connecting portion 10a, a fourth connecting portion 10b, and a lateral connecting portion 10d, all of which have a slot-type structure. The third connecting portion 10a is used to insert and fit into the upper end of the front support leg 8, the fourth connecting portion 10b is used to insert and fit into the lower end of the front support rod 9, and both ends of the lateral connecting rod 72 are inserted and fitted into the lateral connecting portions 10d of the two connecting seats 10. As a result, the front support rod 9 and the front support leg 8 are stably attached by the connecting seat 10, and a strong load-bearing support point is formed.

[0027] Furthermore, the connecting seat 10 is further provided with a second insertion groove 10c, which allows the front support rod 9 and / or front support leg 8 to be inserted into the insertion groove and positioned in the front-to-back direction when the rocking chair is folded, enabling compact storage.

[0028] Specifically, as shown in Figure 1, an elastic member 4 is positioned and mounted between the upper support seat 1 and the lower support seat 2. When the upper support seat 1 swings relative to the lower support seat 2, the elastic member 4 deforms and provides a restoring force to the swing. In this embodiment, the elastic member 4 is a helical compression spring, with its upper and lower ends positioned within the first spring seat 13 and the second spring seat 25, respectively, and the compression spring is located in front of the rotation axis 3. When the upper support seat 1 swings, the elastic member 4 is compressed, generating an elastic restoring force, ensuring that the backrest automatically returns to its initial position after tilting forward or rocking backward, thus avoiding misalignment.

[0029] Specifically, as shown in Figure 10, the front support leg 8 and the rear support leg 5 are tubular structures, and snap hooks 51 are attached inside them. When the rear support leg 5 is inserted into the second connecting portion 21, the snap hooks 51 can reliably engage with the inner wall of the second connecting portion 21, thereby enabling a positioning function during folding or unfolding operations.

[0030] Furthermore, as shown in Figures 5 and 6, the upper support seat 1 and the lower support seat 2 are equipped with a first position restricting portion 15 and a second position restricting portion, respectively. In this embodiment, the second spring seat 25 has a boss structure and functions as the second position restricting portion. When the upper support seat 1 swings to one end of its stroke relative to the lower support seat 2, the first position restricting portion 15 contacts the lower support seat 2, preventing excessive rearward locking. When it swings to the other end, the upper end of the second spring seat 25 contacts the upper support seat 1, preventing excessive forward tilting, thereby ensuring that the locking stroke is within a reasonable range.

[0031] Specifically, in use, the front support legs 8 and rear support legs 5 cooperate with each other to form a stable force-receiving support structure, ensuring the stability of the rocking chair during use. There are at least three front support legs 8 and rear support legs 5 in total, and at least three front support rods 9 and rear support rods 6 in total. In this embodiment, a design consisting of two front support legs 8, two rear support legs 5, two front support rods 9, and two rear support rods 6 is adopted. The front support rods 9 always remain fixed, and the position of the front edge of the chair fabric connected to their upper ends does not shift with rocking. Therefore, after the user sits down, the front edge of the chair fabric can stably support the inside of the thighs. When the user's body tilts forward or rocks backward, the contact point with the thighs always remains unchanged, providing a psychologically higher sense of stability and security.

[0032] Furthermore, as shown in Figure 7, after unfolding the rocking chair, the upper support seat 1 has an initial state in which it is at any angle between forward tilt and backward rocking relative to the lower support seat 2. When a person sits on the chair fabric, the weight of the person's body is transmitted to the upper support seat 1 by the chair fabric, which displaces slightly, and the seat surface of the chair fabric deforms appropriately, improving the feeling of being enveloped and the comfort. In another embodiment, the initial state corresponds to the forward tilt position, and when seated, the seat surface hardly deforms, providing a stable seating feel. Subsequently, when the back leans against the backrest area, the upper support seat 1 swings backward accordingly and returns slowly under the action of the elastic member 4, further improving the user experience.

[0033] In this embodiment, the rocking chair is used as follows. First, the user unfolds the rocking chair from its folded state, and the front support legs 8 and rear support legs 5 come into contact with the ground to form a stable support. When the user sits on the chair's fabric seat, the weight of the user's body is transmitted to the upper support seat 1, causing the rear support rod 6 to swing and tilt the backrest area forward. When the user leans their back against the chair's fabric backrest area and applies a backward force, the rear support rod 6 swings backward accordingly, achieving backward rocking of the backrest area. Under the action of the elastic member 4, the backrest area can swing back and forth according to the rear support rod 6, thereby realizing the forward and backward rocking function of the rocking chair. Because the front support rod 9 is fixed and the front edge of the chair fabric does not displace, after use, the chair can be compactly folded and stored by inserting the front support rod 9 and front support legs 8 into the second insertion groove 10c of the connecting seat 10, and the rear support rod 6 and rear support legs 5 into the first insertion groove 23 of the lower support seat 2.

[0034] Example 2 As shown in Figure 12, various deformations can be applied to the structural form of the elastic member 4. In this embodiment, the elastic member 4 is a tension spring, with both ends of the tension spring connected to the upper support seat 1 and the lower support seat 2, respectively, and the tension spring is located on the rear side of the rotation axis 3.

[0035] Example 3 As shown in Figure 13, in this embodiment, the elastic member 4 employs a torsion spring structure, and the torsion spring is externally mounted on the outside of the rotation shaft 3, with both ends contacting the lower end surface of the upper support seat 1 and the upper end surface of the lower support seat 2, respectively. In some other embodiments, the spring member 4 can use a leaf spring instead of the torsion spring structure in this embodiment.
