Description

Folding trampoline with safe and easy hinge structure

The present invention relates to a trampoline that can enjoy play through a repetitive jumping motion and obtain a movement effect, and more particularly, to a foldable trampoline that has a safe and simple folding structure when the trampoline is opened or used or folded and stored.

In general, trampoline is a playground equipment that enjoys play through repetitive jumping motions, which can give fun to children of growing age and improve the flexibility and balance of the body. Recently, it has the advantage of being able to perform aerobic exercise and strength training at the same time. It is a trend that is widely used as an adult exercise equipment for health diet by utilizing.

The basic structure of the trampoline consists of a circular or polygonal outer frame with a certain height, and a high-elasticity springboard made of an elastic material is provided in the frame to fix the frame of the springboard to the frame using an elastic connecting material such as a spring or rubber rope. By doing so, it is configured to allow the user to perform repetitive jumping motions using a jump plate fixed to the frame.

However, such a trampoline is very bulky because the user must occupy a certain space in order to secure a point where it can fall when performing a repeated jumping operation, and the conventional trampoline is a fixed frame, which is too large to be used. In this case, there is a problem in that it only takes up space unnecessarily.

In particular, the trampoline exercise effect has been proven recently, and trampoline is mainly used as a personal exercise equipment at home. In many places, such as a health club, several trampolines are placed to exercise as a group of people. Since the trampoline of occupies too much space, there is a problem that storage is difficult when not in use.

Therefore, a technique has been proposed to fold the trampoline frame and store it in a foldable manner as a way to solve this problem.

A trampoline disclosed in Korean Patent No. 1775308 is disclosed as a prior art that allows the frame to be folded and stored, which allows the frame provided on the border of the trampoline to be composed of several pieces, while a collapsible pillar is provided at the connecting portion of the frame piece. It is configured so that when the trampoline is not used, it can be folded and stored.

However, the trampoline provided with a pillar is a structure applied to a large trampoline used by many people at the same time, and since the trampoline used for personal exercise such as a child or a home or a health club is mostly small, the pillar itself is not required. There is a problem that the above method cannot be applied because is the most.

As another conventional technique, in the Republic of Korea Utility Model No. 447000, a method is provided in which a folding connector is provided on a frame, and the connector is fixed by bolts so that it can be folded and stored when not in use. There is a problem in that it is very cumbersome to use because a separate tool is required when opening or folding the perlin.

In addition, since the structure is simply bolted, there is a possibility that the connection portion flows while the trampoline is expanded.

That is, there is a possibility that the connection part of the frame may become loose when a continuous impact acts on the frame due to repeated jumping motion, and when the load is concentrated to either side, the connection part of the frame may be folded by the impact and it is safe. There is a risk of an accident.

Also, when trampoline is used by infants or children, there is a case where an infant or child crawls under the trampoline in a gap where the caregiver's attention is disturbed. However, there is a danger that the child may get caught in the frame or the infant or child playing on the trampoline may be seriously injured.

Republic of Korea Utility Model No. 447000 (Dec. 08, 2009) Republic of Korea Registered Patent No. 1775308 (2017.08.30.)

The base body is formed to surround the outer surface of the frame bar, and is fixed to the other side frame bar of the connecting portion, and the working body is assembled to the base body, and the frame bar of the connecting portion is collapsible while the working body is assembled to the base body. A hinge assembly for hinge operation, and a section of the base body and the operation body Block the operation to be one, and at the same time so the trampoline optionally unfolded by the locking means in the expanded state so as to be folded to a storage ever trampoline comprises a locking means for preventing any collapse of the frame bar.

In addition, the locking means blocks the folding operation between the base body and the actuator while the base body and the actuator are assembled by the hinge assembly, and reaches a position set by the press and By including an elastic element for restoring to the original position and a moving slit for limiting the movable range of the presser, the user can easily unfold or fold the frame with one touch.

Further, on the surface of the pressing plate, an indentation portion having a diameter smaller than the outer diameter of the pressing rod is formed, and a corresponding guide portion provided with a diameter of the pressing portion and an outer diameter of the pressing rod is provided in the corresponding moving slit. An extension hole is formed to limit the movement of the presser bar, and when the presser bar reaches a set position, it is locked while being inserted into the expansion hole.

In addition, the folding device divides the frame and the folding device is mounted on the connecting portion of the divided frame bar so that the frame can be folded in half, or the frame is divided into four and the folding device is mounted on the connecting portion of each frame bar. It was made to be folded in two stages.

According to the foldable trampoline having a safe and simple folding structure of the present invention, the frame can be folded and stored by a simple operation of the user, so space utilization can be efficiently performed, and since the trampoline is fixed in the unfolded state, accidents are prevented by preventing any folding. Can be prevented.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the trampoline of the present invention is composed of a frame 1 made of a circular or polygonal frame, and an inner frame is provided with a spring plate 2 made of an elastic material, and the border of the spring plate is elastic. To be fixed to the frame using the connecting material 3, the frame 1 is equipped with a leg 4 so that the frame and the jumping plate are mounted to have a constant height from the ground, so that a jumping operation using the jumping plate can be performed. .

At this time, the frame 1 may be divided into a plurality of frame bars 1a, and a folding device 10 may be mounted on the connection portion of the frame bar to control and fold the frame.

That is, when the frame 1 is formed in a circular shape, the frame is bisected to provide two semi-circular frame bars 1a, and a folding device 10 can be mounted on the connecting portion of the frame bar. ) Even if it is made of a polygon, the trampoline can be folded and stored by dividing the frame so that the frame can be folded in half.

The folding device 10 has a base body 100 and a working body 200 which are fixed to the connecting portions of the divided frame bar 1a, respectively, as shown in FIGS. 2 and 3, and the base body and the working body. It may be configured to include a hinge assembly 300 to be collapsible, and a locking means 400 for controlling the folding operation by the hinge assembly.

The base body 100 is fixed to one side of the frame bar of the connecting portion of the frame bar 1a, and may be formed to surround the outer surface of the frame bar. To this end, the base body 100 has a U-shaped plate material The penetrating portion 120 may be provided to be accommodated by bending, and the frame bar may be accommodated in the penetrating portion 120 to be fixed by welding or the like.

In addition, the actuator 200 is fixed to the other frame bar among the connecting portions of the frame bar 1a, and is assembled and operated in the base body 100. To this end, the actuator 200 is bent and formed on one side thereof. A joining surface 220 for fixing the frame bar is formed and can be fixed by welding or the like in a state where the frame bar on the other side is in close contact.

At this time, the inner surface of the through portion 120 formed in the base body 100 and the outer surface of the bonding surface 220 formed in the working body 200 is preferably manufactured to correspond to the shape of the cross section of the frame bar 1a. That is, when the cross-section of the frame bar 1a is formed in a circular shape, the inner surface of the through portion 120 and the outer surface of the bonding surface 200 are formed in an arc shape so as to be in close contact with the outer periphery of the frame bar 1a. When the cross-section is made of a polygon, the inner surface of the through portion 120 and the outer surface of the bonding surface 200 may be made to be bent to correspond to the polygon so as to be in close contact with the outer periphery.

The hinge assembly 300 is to enable the frame bar of the connection portion to be hinged so that the operating body is assembled to the base body, and the hinge shaft 360 is formed in the shaft holes 320 and 340 respectively formed in the base body and the operating body. By inserting the base body and the actuator may be provided to be hinged.

Therefore, the frame body of one side of the connecting portion of the frame bar where the frame is divided is provided with a base body and a working body fixed to the frame bar of the other side so that the frame of the trampoline is foldable by hinge operation.

On the other hand, the locking means 400 is to prevent any folding of the frame bar by blocking the folding operation of the base body and the actuator, the locking means 400 is assembled by the hinge assembly with the base body and the actuator In the state of the pressing body 420 for blocking the folding operation between the base body and the operating body or to control the start of the operation, and the elastic element 440 for restoring to the correct position when the pressing table reaches the set position, It may be configured to include a moving slit 460 for limiting the range of movement of the pressing bar.

The pressing plate 420 is formed in a substantially cylindrical shape and is assembled through the base body and the operating body, and the inner peripheral surface is provided with an inlet portion 422 having a diameter relatively smaller than the outer diameter of the pressing plate. , The moving slit 460 is provided with a guide portion 462 provided to correspond to the inlet diameter of the presser and an outer diameter of the presser to form an extension hole 464 for limiting the movement of the presser, thereby forming the presser The operation of fixing and releasing the folding device 10 is made.

At this time, the pressing table 420 is provided with a head portion 424 that protrudes to be exposed to the outside of the base body so that the user can release the fixing state of the pressing plate by pressing the head portion. It can be mounted to be elastically restored by the elastic element 440 in an assembled state so as not to be detached by being fixed with a snap ring 428 and assembled with an axial pin 426 on the actuator 200 bent in a U-shape shape. .

Therefore, as shown in FIG. 4, when the frame is extended, the head portion of the pressing plate 420 protrudes to the outside of the base body 100 by the elastic restoring force of the elastic element 440, so that the pressing plate 420 expands the hole ( 464), the folding operation is limited, preventing the trampoline from being folded arbitrarily and maintaining a stable spread state.

And when the user presses the presser bar 420 as shown in FIG. 5, the locking device 400 is released while the inlet part 422 of the presser bar is switched to a state where it can enter the guide part 462 of the moving slit 460. In this state, when the user folds the frame bar 1a, as shown in FIGS. 6 to 8, the presser 420 moves on the moving slit 460 and the frame is foldable.

Therefore, the frame can be folded and stored by a simple operation of the user, thereby enabling efficient use of space.

On the other hand, if you want to expand the trampoline, as shown in Fig. 9, when the frame bar 1a is unfolded, the frame folds while the presser 420 moves on the movement slit 460, and the presser 420 moves the slit At the same time as reaching the end of 460, the pressing table 420 is protruded through the expansion hole 464 by the elastic restoring force of the elastic element 440, so that the locking is made.

At this time, the pusher 420 is inserted into the insertion portion 427 is inserted to insert the shaft pin 426, the shaft 4 is inserted into the elastic element 400 in the state where the pin 426 is inserted By being assembled to have elastic restoring force, the depth at which the pusher is inserted when the user presses the pusher to release the locking device is the depth of the insertion portion 427 formed in the pusher 420 or the shaft pin for fixing the pusher ( 426) can be appropriately set.

In addition, the shaft pin 426 is rotated in a state in which the head portion of the shaft pin is in close contact with the inner surface of the base body 100 when the actuator 200 is rotated while the pusher is pressed, minimizing friction with the base body And for smooth folding operation, it is desirable that the head portion of the shaft pin is formed in a round shape.

Therefore, while the locking means operates in one touch by the pressing bar, the spreading or folding path is induced by the moving slit, so that the frame is stably expanded or folded when the frame is expanded or folded.

In addition, as described above, the movable slit 460 forms an extension hole 464 only at one end of the guide portion 462 corresponding to the unfolding angle of the frame bar fixed to the base body and the actuator, or FIG. 11. As shown in the expansion body 464 may be formed at both ends of the guide portion 462, respectively, corresponding to the unfolding angle and the folding angle of the frame bar fixed to the base body and the actuator, respectively.

Therefore, if necessary, the frame may be fixed only in the unfolded state, or may be manufactured to be fixed in both the unfolded state and the folded state.

Meanwhile, as shown in FIGS. 12 and 13, the folding device 10 may be equipped with a folding device 10 on a connecting portion divided into four to divide the frame bar into four equal parts and be foldable into two stages.

At this time, the folding device 10 for the efficient folding of the frame, the connecting portion of the frame bar that is folded in one step, that is, the portion that is folded in half by dividing the frame so that the frame bar is folded to the bottom, and in two steps. The connection part of the frame bar where the folding is made, that is, the part folded back in a state in which the frame is folded in half, allows the frame bar to be folded in the lateral direction, so that the trampoline can be folded and stored at a minimum volume without being jammed when folded and stored.

Therefore, by folding each of the folding devices 10 on the connection parts divided into four parts, the frame is folded in half or, if necessary, folded into four parts so that it can be moved and transported.
