Description

Technical Field

[0001] The present invention relates to a seesaw, and more specifically, to a vertically lifting seesaw, belonging to the field of sports facilities. Background Art

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

[0003] There are also some patented technologies that attempt to change the technical principle to achieve a new movement mode of the seesaw. For example, "A Hydraulic Transmission Seesaw", application number 202011345874.2, where paragraph

[0013] records that through a hydraulic center and hydraulic seats, based on the Pascal hydrostatic principle, a seesaw game for two or more people can be completed. Paragraph

[0021] records that if the distance between the hydraulic seat and the hydraulic center is insufficient, a hydraulic conduit with a push rod check valve at both ends is connected in series between the hydraulic seat and the hydraulic center; if a person does not want to participate in the game and does not affect others playing the seesaw game, only need to close the stop valve 19 on the hydraulic center corresponding to its hydraulic seat. The above technology can be flexibly arranged according to the actual situation, but due to the technical principle it adopts, there will also be problems in actual use, such as the movement of the seesaw being too slow and uninteresting to use, the product being too heavy to be easily arranged, and the facility being expensive.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present 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 accompanying 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.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "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 at various places do not affect the multi-position folding of the present 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.

[0031] The creativity of the present invention lies in adopting a set of link mechanisms to provide the seesaw seat with the movement characteristic of reciprocating movement in the vertical direction, combined with a buffer shock-absorbing device, thereby solving the defect that users are easily thrown out by inertia under the arc-shaped movement track of the traditional seesaw seat.

[0032] Such as Figures 1-10The following shows a specific embodiment of a vertical lift seesaw according to the present invention. The vertical lift seesaw includes a support 1, a rocker 2, and symmetrically arranged left seat 3 and right seat 4. The left and right ends of the support 1 are respectively vertically provided with a left vertical sliding groove 1.1 and a right vertical sliding groove 1.2. The left seat 3 and the right seat 4 are respectively slidably arranged up and down on the left vertical sliding groove 1.1 and the right vertical sliding groove 1.2. The middle part of the rocker 2 is rotatably connected to the support 1 between the left vertical sliding groove 1.1 and the right vertical sliding groove 1.2. The left and right ends of the rocker 2 respectively extend to the outside of the support 1, and left horizontal sliding grooves 2.1 and right horizontal sliding grooves 2.2 are arranged on the rocker 2. Left rotating shafts 3.3 and right rotating shafts 4.3 are respectively arranged on the left seat 3 and the right seat 4. The left rotating shafts 3.3 and the right rotating shafts 4.3 are respectively slidably arranged left and right in the left horizontal sliding grooves 2.1 and the right horizontal sliding grooves 2.2 to realize the linkage of the left seat 3 and the right seat 4 through the rocker 2. The linkage method is: the alternating lifting of the left seat 3 and the right seat 4.

[0033] The usage method of the present invention is specifically as follows: As Figures 1-8 shown, the seesaw can realize the alternating lifting of the left seat 3 and the right seat 4.

[0034] Usage state 1: As Figure 1 、 Figure 2 shown, when preparing to use or after use, the left and right users' feet touch the ground, the rocker 2 is in a left and right flattened state, the left seat 3 and the right seat 4 are at the same height, and the left rotating shafts 3.3 and the right rotating shafts 4.3 are respectively at the positions closer to the inside of the left horizontal sliding grooves 2.1 and the right horizontal sliding grooves 2.2 (close to the center of the rocker 2). During the use process, the movement of the seesaw will also go through the illustrated positions.

[0035] Usage state 2: As Figure 4 、 Figure 5 、 Figure 6 shown, when the left user presses down on the seat (left seat 3) and the right user pedals the ground, the left seat 3 descends, the right seat 4 ascends, the left end of the rocker 2 rotates downward, and the right end rotates upward, that is, the left horizontal sliding groove 2.1 rotates downward, and the right horizontal sliding groove 2.2 rotates upward. Under the transmission of the acting force on the left rotating shafts 3.3 and the right rotating shafts 4.3, the left slider 3.2 is pushed to drive the left seat 3 to move downward under the constraint of the left vertical sliding groove 1.1, and the right slider 4.2 is pushed to drive the right seat 4 to move upward under the constraint of the right vertical sliding groove 1.2. When the seat is at the maximum ascending and descending positions, the shock-absorbing pads 5 come into contact with the upper and lower surfaces of the left slider 3.2 and the right slider 4.2. Under the action of the shock-absorbing pads 5, the moving speeds of the left seat 3 and the right seat 4 gradually decrease to 0, playing a role in buffering and shock absorption, as Figure 6 shown.

[0036] Usage state 3: As Figure 7 、Figure 8 In the state shown, when the user on the right presses down the seat (right seat 4) and the user on the left pedals the ground, the right seat 4 descends, the left seat 3 ascends, the left end of the rocker 2 rotates upward, and the right end rotates downward, that is, the right horizontal chute 2.2 rotates downward and the left horizontal chute 2.1 rotates upward. Under the transmission of its acting force through the left rotating shaft 3.3 and the right rotating shaft 4.3, the right slider 4.2 is pushed to drive the right seat 4 to move downward under the constraint of the right vertical chute 1.2, and the left slider 3.2 is pushed to drive the left seat 3 to move upward under the constraint of the left vertical chute 1.1.

[0037] Compared with the existing traditional seesaw device, the present invention enables the seats of the seesaw to achieve vertical lifting movements, avoiding the use risks brought by the arc movement trajectory of the traditional seesaw seats. A buffer device is added at the maximum movement position to avoid the occurrence of human body out-of-control under strenuous exercise conditions. The structure is safe and reliable, with high durability. The overall structure is simple, easy to install and move on-site, simple to repair and maintain, easy to mass-produce and promote in the market, and has good market value and social value.

[0038] In a preferred embodiment, a left support rod 3.1 is connected to the left seat 3. The right end of the left support rod 3.1 is connected to a left slider 3.2 and a left rotating shaft 3.3. The left rotating shaft 3.3 is slidably installed in the left horizontal chute 2.1, and the left slider 3.2 is slidably installed in the left vertical chute 1.1. A right support rod 4.1 is provided on the right seat 4. The left end of the right support rod 4.1 is connected to a right slider 4.2 and a right rotating shaft 4.3. The right slider 4.2 is slidably installed in the right vertical chute 1.2, and the right rotating shaft 4.3 is slidably installed in the right horizontal chute 2.2 on the rocker 2. A set of link mechanism is adopted, and the link mechanism includes the left support rod 3.1, the right support rod 4.1, and the rocker 2, realizing the movement characteristics that the left seat 3 and the right seat 4 reciprocate in the vertical direction. Combined with the buffer and shock absorption device, the defect that the user of the traditional seesaw seat is easily thrown out by inertia under the arc movement trajectory is solved.

[0039] The function of the left and right vertical sliding grooves and the sliders on the bracket 1 is the key to realizing the up and down displacement of the seat. When adding a magnetic levitation feature to the left slider 3.2 and the right slider 4.2 or replacing the sliders with pulleys and gear chains to achieve the same technical effect, it belongs to the alternative solution of this application and does not belong to a creative and substantial change. There is a dual movement of rotation and sliding between the seat rotating shafts (left rotating shaft 3.3 and right rotating shaft 4.3) and the left and right horizontal sliding grooves on the rocker 2. When using one or more ball rotating shafts to achieve the same technical effect, it belongs to the alternative solution of this application and does not belong to a creative and substantial change. This application preferably adopts a symmetric structure. When the rocker mounting holes 1.3 on the bracket 1 are not centered, and the lengths and angles of the left and right horizontal sliding grooves of the rocker 2 are asymmetrically set, the seesaw can still work normally, which belongs to the alternative solution of this application and does not belong to a creative and substantial change.

[0040] Preferably, in one embodiment, two rockers 2 are provided and symmetrically arranged on the front and rear sides of the bracket 1. A rocker mounting hole 1.3 is formed on the bracket 1 between the left vertical sliding groove 1.1 and the right vertical sliding groove 1.2. A rocker rotating shaft 2.3 is connected between the middle parts of the two rockers 2. The rocker rotating shaft 2.3 is rotatably installed in the rocker mounting hole 1.3 to achieve hinging. Specifically, as shown in Figure 2 , Figure 3 shown, the rocker rotating shaft 2.3 is installed in the rocker mounting hole 1.3, the left slider 3.2 on the left seat 3 is installed in the left vertical sliding groove 1.1 of the bracket 1, and the left rotating shaft 3.3 is installed in the left horizontal sliding groove 2.1 of the rocker 2. The right seat is symmetrically installed at the opposite position. The height difference between the ascending heights of the left seat 3 and the right seat 4 depends on the position height of the rocker mounting hole 1.3, the groove lengths of the left and right vertical sliding grooves 1.1 and 1.2, and the relationship among the groove lengths of the left and right vertical sliding grooves 1.1 and 1.2. The three are positively correlated. When the lengths of all three increase, the left seat 3 and the right seat 4 can be raised to a higher position. When one of the three dimensions decreases, the ascending and descending heights of the left seat 3 and the right seat 4 decrease.

[0041] Two left support rods 3.1 are provided. The right ends of the two left support rods 3.1 are respectively connected with a left rotating shaft 3.3. The two left rotating shafts 3.3 are respectively connected with a left slider 3.2, and the two left sliders 3.2 are integrally formed. The two left rotating shafts 3.3 are respectively slidably arranged in the left horizontal sliding groove 2.1 of a rocker 2. Two right support rods 4.1 are provided. The left ends of the two right support rods 4.1 are respectively connected with a right rotating shaft 4.3. The two right rotating shafts 4.3 are respectively connected with a right slider 4.2 and the two right sliders 4.2 are integrally formed. The two right rotating shafts 4.3 are respectively slidably arranged in the right horizontal sliding groove 2.2 of a rocker 2. The structure adopts a symmetric clamping method, making the structure firm, with high aesthetic value and strong practicability.

[0042] Preferably, in an embodiment, the left rotating shaft 3.3 is rotatably connected between the left slider 3.2 and the left support rod 3.1, and the right rotating shaft 4.3 is rotatably connected between the right slider 4.2 and the right support rod 4.1. When the left horizontal sliding groove 2.1 and the right horizontal sliding groove 2.2 rotate, the left rotating shaft 3.3 and the right rotating shaft 4.3 slide in the left horizontal sliding groove 2.1 and the right horizontal sliding groove 2.2 respectively. At this time, there is sliding friction, and the wear is large after long-term use. The left rotating shaft 3.3 and the right rotating shaft 4.3 are set as rotatable structures, so that when the left rotating shaft 3.3 and the right rotating shaft 4.3 move in the left horizontal sliding groove 2.1 and the right horizontal sliding groove 2.2, they roll by themselves, realizing rolling friction, greatly reducing the friction force, improving the operation fluency, and making the action response faster.

[0043] The left and right horizontal sliding grooves on the rocker 2 are symmetrically arranged left and right. When it makes a reciprocating rotational motion around the rocker mounting hole 1.3 after being assembled and installed with the bracket 1, the rotating shafts on the left and right seats rotate around the normal direction of the horizontal sliding groove and slide along the constraint axis of the horizontal sliding groove. Under the constraint of the left and right vertical sliding grooves on the bracket 1 that limit the up and down movement of the left and right seats, the left and right seats slide up and down in the left and right vertical sliding grooves on the bracket 1, and the rotating shafts rotate and slide between the horizontal sliding grooves on the rocker 2.

[0044] Preferably, in an embodiment, shock pads are connected to the upper and lower ends of the left vertical sliding groove 1.1 and the right vertical sliding groove 1.2 for deceleration and buffering, improving the comfort and avoiding large inertia caused by impact. The shock pads can also use springs or other means to achieve the same effect.

[0045] Preferably, the rocker 2 includes a V-shaped member with an upward opening. The two ends of the opening of the V-shaped member are respectively connected with a left end part and a right end part. The left end part and the right end part are symmetrically arranged left and right. And when the opening of the V-shaped member faces directly upward, the left end part and the right end part are horizontal. The left horizontal sliding groove 2.1 and the right horizontal sliding groove 2.2 are respectively opened on the left end part and the right end part. The rocker rotating shaft 2.3 is installed at the vertex of the V-shaped member. Through the setting of the V-shaped member, the rising and falling amplitudes of the left seat 3 and the right seat 4 can become larger, the rotation response of the rocker 2 is faster, and it can be closely matched with other structures. However, the existing seesaw design only uses a horizontal crossbar as a lever, with a slow response and less smooth rotation at the vertex of the V-shaped member.

[0046] Preferably, in an embodiment, when the left slider 3.2 is located at the bottom end of the left vertical sliding groove 1.1, the right slider 4.2 is located at the top end of the right vertical sliding groove 1.2. When the left slider 3.2 is located at the top end of the left vertical sliding groove 1.1, the right slider 4.2 is located at the bottom end of the right vertical sliding groove 1.2. Such a structure is stable, and it can also be set not to reach the bottom end or the top end at the same time. However, in this case, there is only one support point, which causes great damage to the structure.

[0047] In a preferred embodiment, the bracket 1 includes a left bracket, a right bracket and a horizontal bar connected between the left bracket and the right bracket, the left vertical slide groove 1.1 and the right vertical slide groove 1.2 are respectively located on the left bracket and the right bracket, the rocker mounting hole 1.3 is located in the middle of the horizontal bar, and a plurality of connecting rods are connected between the left bracket and the right bracket located above the horizontal bar. The multiple connecting rod structures can be arranged in curved, straight or other shapes, so that the overall structure is beautiful and firm.

[0048] In a preferred embodiment, the lengths of the left end and the right end are both less than or equal to the length of the left support rod 3.1, and the left support rod 3.1 and the right support rod 4.1 are of the same length. Figure 2 , Figure 5 , Figure 8 As shown, the length of the left support rod 3.1 and the right support rod 4.1 determines the distance between the players, but has no effect on the lifting height of the left seat 3 and the right seat 4. The lengths of the left support rod 3.1 and the right support rod 4.1 can be set to unequal lengths. In this specific example, an equal length setting is selected.

[0049] Finally, it should be noted that the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by ordinary technicians in this field should be considered as the protection scope of the present invention.
