Description

Technical Field

[0001] The present invention relates to a seesaw, and more specifically, to a multi-mode children's companion seesaw, belonging to the field of sports facilities. Background Art

[0002] A seesaw is a relatively common sports and entertainment facility. Currently, the patent technologies of seesaws pay more attention to versatility, safety, and adaptability. For example, the patent technologies of "A Seesaw Self-Balancing Device and Its Control Method" with application number 202011277138.8, "An Adjustable Seesaw" with application number 202010404207.0, and "A New Type of Multi-Functional Automatic Adjustment Fitness Seesaw" with application number 201910950283.9 all solve the use problems of seesaws when there is a large difference in weight on both sides through different technical means. Another example is that the patent technologies of "A Children's Seesaw with a Protection Function" with application number 202011200486.5 and "An Active Protection Type Seesaw for Preventing the Head-Tipping Phenomenon" with application number 202011153319.X all solve the safety problems existing in conventional seesaws through different technical means.

[0003] There are also some patent technologies that focus on the role of seesaws in parent-child entertainment. For example, "A Seesaw Suitable for Parks" with application number 201810699113.3 discloses that "

[0015] While playing on the seesaw, the cradle is moved, achieving the effect of being able to play on the seesaw and take care of the child at the same time, and the child will not fall and get injured." Another example is "A Seesaw" with application number 201810608189.0, which discloses that "

[0016] When the elderly or adults perform arm exercise operations on the support arm, they can drive the children on the seat on the other side to swing up and down, forming an interaction between the two, increasing the interaction fun, etc., and solving the problem that it is difficult for the elderly to accompany children to play on the seesaw." The above two patent technologies have both made attempts in the way of companion entertainment. However, the former technology takes into account the care of the cradle on the basis of adult play, and the latter technology coordinates the movement of the children's seesaw with adult upper limb exercise, and does not solve the problem of how adults and children can safely and interestingly participate in the seesaw game together.

[0004] Therefore, in the current seesaw field, it will have practical positive significance to provide new movement actions for seesaws on the basis of taking into account the actual technology and market feasibility. Summary of the Invention

Detailed implementation manners

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0049] In the description of the invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0050] In the description of the invention, it should be noted that unless otherwise clearly specified and limited, terms such as "installation", "setting", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an indirect connection through an intermediate medium. However, the connections in each place do not affect the multi-position folding of this application. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0051] The creativity of the present invention lies in the adoption of a set of link mechanisms, combined with sliding and rotating movements, realizing that one side of the seesaw can perform reciprocating rotational movements, and the other side can perform reciprocating vertical movements, and realizing the switching of multiple motion modes by changing the locking conditions of the two left and right fulcrums, which not only meets the needs of adults to achieve multiple playing methods, but also solves the problem that young children cannot control a conventional seesaw and there are also movement risks at the same time.

[0052] Such as Figures 1 - 30Shown is a specific embodiment of a multi-mode children's companion seesaw. This embodiment is a multi-mode children's companion seesaw, including a support 1, a children's chair 2, an adult chair 3, a horizontal sliding shaft 4, and a horizontal sliding shaft sleeve 5. The support 1 is provided with a horizontal sliding groove 1.1 and a vertical sliding groove 1.2. On the support 1 on both the upper and lower sides of the horizontal sliding groove 1.1, sliding shaft positioning holes 1.3 are provided. The adult chair 3 is connected with a first connecting plate, and the end of the first connecting plate extends obliquely upward to form a second connecting plate. The first connecting plate and the second connecting plate are provided with a communicating chair rod sliding groove 3.1. A card slot is provided on the outer peripheral surface of the horizontal sliding shaft 4. The horizontal sliding shaft 4 is simultaneously located in the horizontal sliding groove 1.1 and the chair rod sliding groove 3.1 on the first connecting plate. A horizontal sliding shaft sleeve 5 is detachably provided on the horizontal sliding shaft 4 between the horizontal sliding groove 1.1 and the first connecting plate. A clamping member is provided on the inner wall of the horizontal sliding shaft sleeve 5. The clamping member is matched with the card slot to form an assembly lock. A horizontal sliding shaft sleeve bolt hole 5.2 is provided on the horizontal sliding shaft sleeve 5. By passing a bolt 8 through the horizontal sliding shaft sleeve bolt hole 5.2 and the sliding shaft positioning hole 1.3, the position of the horizontal sliding shaft 4 in the horizontal sliding groove 1.1 can be positioned;

[0053] The children's chair 2 is connected with a third connecting plate. The third connecting plate is connected with a rotating shaft 2.2 located in the chair rod sliding groove 3.1 and a slider 2.1 located in the vertical sliding groove 1.2. The slider 2.1 can slide up and down in the vertical sliding groove 1.2. It further includes a vertical rotating shaft sleeve 7. The vertical rotating shaft sleeve 7 is located outside the second connecting plate and is sleeved on the rotating shaft 2.2 through a shaft hole 7.1. A vertical rotating shaft sleeve bolt hole 7.2 is provided on the vertical rotating shaft sleeve 7. A vertical rotating shaft sleeve bolt hole 3.3 is provided on the second connecting plate. By using a bolt 8, the vertical rotating shaft sleeve 7 can be fixed to the vertical rotating shaft sleeve bolt hole 3.3 to position the rotating shaft 2.2 in the chair rod sliding groove 3.1.

[0054] Structure 1. When using a bolt 8 to connect the horizontal sliding shaft sleeve 5 and / or the outer shaft sleeve 6 with the shaft sleeve positioning hole 3.2 on the first connecting plate, the first connecting plate (i.e., the adult chair 3) can slide left and right in the horizontal sliding groove 1.1 and the first connecting plate can rotate up and down, further cooperating with Structure 3.

[0055] Structure 2. When using a bolt 8 to connect the horizontal sliding shaft sleeve 5 and the sliding shaft positioning hole 1.3 on the support 1, the position of the horizontal sliding shaft 4 in the horizontal sliding groove 1.1 is fixed. The first connecting plate (i.e., the adult chair 3) can only rotate up and down and drive the slider 2.1 to slide up and down in the vertical sliding groove 1.2, further cooperating with Structure 3.

[0056] Structure 3. When the vertical rotating shaft sleeve 7 is fixed to the vertical rotating shaft sleeve bolt hole 7.2 with the bolt 8, the position of the rotating shaft 2.2 is fixed within the chair rod sliding groove 3.1 on the second connecting plate. The second connecting plate only rotates around the rotating shaft 2.2. When the connection of the vertical rotating shaft sleeve 7 is removed, there are dual movements of sliding and rotation between the rotating shaft 2.2 and the chair rod sliding groove 3.1.

[0057] According to the above different connection structures, specifically as Figures 4 - 30 shown, the seesaw has four combined installation modes to achieve diverse movement characteristics:

[0058] Mode 1. Adult chair limited position, children's chair limited position. Adult chair limited position: There are multiple shaft sleeve positioning holes 3.2 at different positions on the adult chair 3 that can be used to connect and fix the horizontal sliding shaft 4 by matching with the horizontal sliding shaft sleeve 5 and the outer shaft sleeve 6. Children's chair limited position: There are multiple vertical rotating shaft sleeve bolt holes 3.3 at different positions on the adult chair 2 that can be connected to the vertical rotating shaft sleeve 7 to limit the rotating shaft 2.2. When the appropriate hole positions are locked according to the required length at the above two positions, when the adult end operates the seat 3 to rotate up and down, the horizontal sliding shaft 4 will select and slide left and right within the horizontal sliding groove 1.1, and the children's chair 2 will move up and down.

[0059] Since the actual rotation center of the adult chair 3 is the axis of the rotating shaft 2.2, and the children's chair 2 is restricted by the vertical sliding groove 1.2 and can only move up and down, so Mode 1 has better movement controllability and safety, and is suitable for novice players.

[0060] Mode 2. Adult chair limited position, children's chair not limited position. Adult chair limited position: As Figures 12 - 18 shown in the state, there are multiple shaft sleeve positioning holes 3.2 at different positions on the adult chair 3 that can be used to connect and fix the horizontal sliding shaft 4 by matching with the horizontal sliding shaft sleeve 5 and the outer shaft sleeve 6. Children's chair not limited position: When the connection of the vertical rotating shaft sleeve 7 is removed, there are dual movements of sliding and rotation between the rotating shaft 2.2 and the chair rod sliding groove 3.1. As Figure 12 、 Figure 13 shown, the adult chair 3 can make only front-back sliding movements without rotating at any position. When the adult chair 3 slides back and forth, the children's chair 2 moves up and down. As Figures 14 - 18 shown, as long as it is within the range restricted by the horizontal sliding groove 1.1 and the vertical sliding groove 1.2, the adult chair 3 can also make front-back sliding movements when rotated to any angle, can perform both rotating and sliding movements simultaneously, or can perform only one of the individual movements, and the children's chair 2 can all achieve lifting and lowering movements.

[0061] Compared with Mode 1, the adult chair in Mode 2 has a higher degree of freedom and more complex movements. Although the fun is further enhanced, the safety is correspondingly reduced, and it is suitable for intermediate players.

[0062] Mode 3. Bracket limited position, children's chair limited position. Bracket limited position: As Figures 19 - 22In the shown state, there are multiple slide shaft positioning holes 1.3 at different positions on the bracket 1 that can be matched with the horizontal slide shaft sleeve 5 to connect and fix the horizontal slide shaft 4. Children's chair limit: There are multiple vertical rotating shaft sleeve bolt holes 3.3 at different positions on the adult chair 3 that can be connected to the vertical rotating shaft sleeve 7 to limit the rotating shaft 2.2. At this time, because the relative positions of the rotating shaft 2.2 and the vertical rotating shaft sleeve bolt holes 3.3 have been limited, the adult chair 3 cannot move forward and backward under the control of the user as in Mode 2, and can only perform up and down rotation operations. However, because the seat rod chute 3.1 is not in a straight line shape, when rotated to certain positions, the position of the horizontal slide shaft 4 will be restricted to match its shape, such as Figure 20 , Figure 21 As shown, at this time, the movement of the adult chair has variable speed and has a certain "bumpy" characteristic.

[0063] Compared with Mode 1, the comfort of using the adult chair in Mode 3 decreases; compared with Mode 2, the controllability difficulty decreases, which is suitable for intermediate players.

[0064] Mode 4. Bracket limit, children's chair not limited. Bracket limit: As Figures 23 - 30 In the shown state, there are multiple slide shaft positioning holes 1.3 at different positions on the bracket 1 that can be matched with the horizontal slide shaft sleeve 5 to connect and fix the horizontal slide shaft 4. Children's chair not limited: When the connection of the vertical rotating shaft sleeve 7 is cancelled, there are dual movements of sliding and rotation between the rotating shaft 2.2 and the chair rod chute 3.1. At this time, the adult chair 3 can move forward and backward only without rotating at any position. When the adult chair 3 moves forward and backward, the children's chair 2 moves up and down. The adult chair 3 can also move forward and backward when rotated to any angle, can perform rotation and sliding movements simultaneously, or can only perform one of the individual movements, and the children's chair 2 can achieve the lifting action. The sliding of the adult chair can be achieved on both sides of the "L" - shaped middle turning position of the chair rod chute 3.1.

[0065] Mode 4 has the action characteristics of Mode 2 + Mode 3. Although the adult chair can achieve the most types of actions and has the highest playability, the control difficulty is also the greatest, and the relative safety is also the lowest, which is suitable for advanced players.

[0066] In a preferred embodiment, it further includes an outer shaft sleeve 6 located outside the first connecting plate. A clamping member is provided on the inner wall of the outer shaft sleeve 6, and the clamping member is matched with the card slot to form an assembly lock. An outer shaft sleeve bolt hole 6.2 is provided on the outer shaft sleeve 6, and a shaft sleeve positioning hole 3.2 is provided on the first connecting plate. By passing a bolt 8 through the outer shaft sleeve bolt hole 6.2 and the shaft sleeve positioning hole 3.2, the position of the horizontal slide shaft 4 in the chair rod chute 3.1 can be positioned.

[0067] Preferably, in an embodiment, a clamping groove is formed around the outer peripheral surface of the horizontal sliding shaft 4. The clamping grooves are located at both ends of the horizontal sliding shaft 4 and are symmetrically arranged. The clamping groove includes a plurality of concave surfaces 4.1 arranged at equal intervals.
