DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-5:

The invention provides a foldable ladder toss game apparatus, comprising frames 100, wherein the number of the frames 100 is at least two, and each frame 100 comprises a telescopic rod 200 and a folding base 300; wherein at least one rung assembly 400 is arranged between two adjacent frames 100, and the rung assembly 400 is able to stretch and retract to adjust a distance between the two adjacent frames 100; wherein, the folding base 300 comprises a connector 301 connected to the telescopic rod 200, and at least two support legs 302; the support legs 302 are rotatably connected to the connector 301 and have a support state and a folded state; when the support legs 302 are in the support state, an included angle is formed between two support legs 302 facing each other; limit assemblies are arranged at joints between the connector 301 and the support legs 302 and used for realizing rotation of the support legs 302 and maintaining the support legs 302 in the support state.

In this embodiment, as shown in FIG. 1, the foldable ladder toss game apparatus comprises two frames 100, and two support legs 302 are arranged at the bottom of each of the two frames 100. The telescopic rods 200 adopt a tube-in-tube form in the prior art and are able to stretch and retract vertically to adjust the overall height of a ladder to satisfy the requirements of different users. The rung assembly 400 is able to stretch and retract to adjust the distance between the two adjacent frames 100 so as to satisfy the requirements of different users. The support legs 302 can be turned on the connector 301; when turned upwards, the support legs 302 come in close fit with the telescopic rod 200 to be folded; on the contrary, when the support legs 302 are turned downwards, an included angle less than 180° will be formed between the two support legs 302 facing each other, and the two support legs 302 work together to support the frame 100 on the same side, such that the whole ladder can be supported and erected to be used.

Preferably, the included angle between the two support legs 302 ranges from 900 to 180°, such that a stable triangular support structure can be formed to improve the stability of the ladder.

According to the above description, by means of the telescopic rods 200 and the rung assembly 400 that can stretch and retract and the support legs 302 that can be turned to be folded, the length, width and height of the ladder can be reduced when the ladder is transported or stored, as shown in FIG. 5, so as to reduce the packing size, thus facilitating transport and storage, reducing transport and storage costs, and increasing economic benefits of products.

In this embodiment, as shown in FIG. 1, the rung assembly 400 comprises a sleeve tube 401 and a movable bar 402, wherein the movable bar 402 is inserted into the sleeve tube 401 and slidably connected to the sleeve tube 401, the sleeve tube 401 is arranged on a side face of one telescopic rod, and the movable bar 402 is arranged on a side face of the other adjacent telescopic rod 200. The movable bar 402 can slide in an axial direction of the sleeve tube 401 to adjust the length of the rung assembly 400 so as to adjust the distance between the two frames 100.

In a possible embodiment, as shown in FIG. 1, a rung assembly 400 may be mounted between the two connectors 301 to improve the stability of the folding bases 300.

In other embodiments (not shown) of the rung assembly 400, the rung assembly 400 may be formed by multiple short bars, and the short bars are detachably connected, for example, by means of bolts or fasteners. In this way, when the ladder is used, multiple short bars can be assembled between the two frames, and the distance between the two frames can be adjusted by changing the number of short bars assembled between the two frames. Of course, when the ladder is transported or stored, the short bars can be detached from the frames to reduce the packing size.

In other embodiments (not shown) of the rung assembly 400, the rung assembly 400 may be formed by multiple short bars that are hinged to each other, and every two adjacent short bars can rotate relatively. When all the short bars are rotated to be in a horizontal state, a horizontal rung is formed and arranged between the two frames 100. In this way, when the ladder is transported or stored, the rung assembly 400 can be folded to reduce the packing size.

In other embodiments (not shown) of the telescopic rod 200, the telescopic rod 200 may also be formed by multiple short bards that are hinged to each other. In use, the short bars can be rotated to be in a vertical state to form a vertical telescopic rod 200. In this way, when the ladder is transported or stored, the telescopic rod 200 can be folded to reduce the packing size.

As shown in FIG. 2-3, the connector 301 is concaved to form a mounting groove 3013, and the bottom of the telescopic rod 200 is mounted at the bottom of the mounting groove 3013. Each support leg 302 has a rotary end and a free end, and the rotary ends of the at least two support legs 302 are arranged in the mounting groove 3013 and respectively located on two sides of the telescopic rod 200. Wherein, in the folded state, the support legs 302 are in close fit with the telescopic rod 200. Each limit assembly comprises a support shaft 3011 and a limit shaft 3012, wherein the support shaft 3011 and the limit shaft 3012 are both inserted into the mounting groove 3013; wherein, a first through-groove 3023 is formed in the rotary end of each support leg 302, and the support shaft 3011 penetrates through the first through-groove 3023. The first through-groove 3023 has a space allowing the support shaft 3011 to slide therein, and has a rotating position and a support position. When the support shaft 3011 is located at the support position, the limit shaft 3012 is located within a radius of rotation of the rotary end; when the support shaft 3011 is located at the rotating position, the limit shaft 3012 is located beyond the radius of rotation of the rotary end. The support legs 302 are hollow, and links 3021 are arranged in the support legs 302 and are close to the free ends of the support legs 302; and elastic elements 3022 are mounted between the links 3021 and the support shafts 3011.

In this embodiment, the first through-grooves 3023 are strip-shaped, and the support shafts 3011 can move in the first through-grooves 3023, for example, the support shafts 3011 can slide or rotate in the first through-grooves 3023. The free ends of the support legs 302 are erected on the ground, and the rotary ends of the support legs 302 are matched with the support shafts 3011 by means of the first through-grooves 3023 and can rotate in the mounting groove 3013 of the connector 301, such that the support legs 301 have the folded state and the support state. Of course, the first through-grooves 2023 are not limited to the strip shape, and may also be T-shaped, Y-shaped or in other geometrical shapes that can realize a limiting effect (not shown).

According to the above description, as shown in FIG. 3, when the support legs 302 are in the support state, the support shafts 3011 slide to ends, away from the telescopic rod 200, of the first through-grooves 3023 (the support positions), at this moment, the limit shafts 3012 are located within the radius of rotation of the rotary ends, and the rotary ends abut against the tops of the limit shafts 3012. In this way, when the free ends of the support legs 302 abut against the ground, the limit shafts 3012 can limit the rotary ends to prevent further rotation of the rotary ends, thus ensuring the support stability of the support legs 302.

When the support legs 302 are in a rotatable state (not shown), the support shafts 3011 slide to ends, close to the telescopic rod 200, of the first through-grooves 3023 (the rotating positions), and at this moment, the limit shafts 3012 are located beyond the radius of rotation of the rotary ends, such that the rotary ends can rotate freely in the mounting groove 3013 to fold the support legs 302 or push the support legs 302 to rotate.

In other embodiments (not shown) of the limit assembly, the limit assembly may realize a limiting effect by snap fit between elastic protrusions and recesses. For example, recesses corresponding to the folded state and the support state are formed in the mounting groove 3013, and the elastic protrusions are mounted on the support legs 302. When the support legs 302 are in the support state, the elastic protrusions are clamped in the recesses corresponding to the support state; and when the support legs 302 are in the folded state, the elastic protrusions are clamped in the recesses corresponding to the folded state. In this way, the support legs 302 are stable enough both in the folded position and in the support position.

Of course, if the support legs 302 have a horizontal state, recesses may be formed in positions where the support legs 302 are placed horizontally. In this way, the support legs 302 can be maintained at the horizontal positions more stably in the horizontal state and will not come loose.

As shown in FIG. 3, to further improve the stability of the support legs 302 in the support state, tensioning mechanisms are arranged in the support legs 302 and used for maintaining the support legs 302 in the support state or in the folded state. Wherein, each tensioning mechanism comprises a connecting rod and an elastic element 3022, the connecting rods are mounted in the support legs 302 and are close to the free ends of the support legs 302, and the elastic elements 3022 are mounted between the connecting rods and the support shafts 3011.

In this embodiment, the elastic elements 3022 are elastic bands, springs or other elastic components, and have a retractive elastic force. In this way, when the support legs 302 are in the support state, the support shafts 3011 can be pulled to abut against the support positions more tightly under the action of the elastic force of the elastic elements 3022, such that the rotary ends are kept in contact with the limit shafts 3012 and prevented from rotating. In this way, the stability of the support legs 302 in the support state is improved.

Of course, the tensioning mechanisms not only can improve the stability of the support legs 302 in the support state, but also can improve the stability of the support legs 302 in the folded state. As shown in FIG. 5, when the support legs 302 are folded upwards and come close to the telescopic rod 200, the tops of the rotary ends will stretch out of the mounting groove 3013 and be limited by bottom edges of the mounting groove (referring to FIG. 3, the mounting groove 3013 has two edges in close fit with the support legs 302 respectively), under the action of the elastic force of the elastic elements 3022, the support shafts 3011 can be pulled to abut against the support positions more tightly, and at this moment, the elastic elements 3022 work together with the edges of the mounting groove 3013 to ensure that the support legs 302 are more stable and unlikely to shake in the folded state.

As shown in FIGS. 2-3, in this embodiment, the support legs 302 also have a horizontal state. Wherein, an end cover 303 is inlaid in the rotary end of each support leg 302 and provided with a clamping structure used together with the corresponding limit assembly.

Specifically, a second through-groove 3031 corresponding to the first through-groove 3023 is formed in the end cover 303, and the support shaft 3011 penetrates through the second through-groove 3031. The clamping structure comprises a recess 3032 formed in an outer surface of the end cover 303; wherein, when the support legs 302 are in the horizontal state, the limit shafts 3012 are inlaid in the recesses 3032.

When the support legs 302 rotate to be in the horizontal state, the recesses 3032 in the end covers 303 will be exactly flush with the limit shafts 3012, and then under the action of the elastic force of the elastic elements 3022, the support legs 302 are pushed to slide towards the limit shafts 3012, and the limit shafts 3012 are clamped in the recesses 3032 to limit the support legs 302, such that the support legs 302 are prevented from rotating.

When all the support legs 302 are in the horizontal state, the contact area between the support legs 302 and the ground will be larger, such that the ladder can be placed more stably and is unlikely to fall.

In other embodiments (not shown) of the clamping structure, the recess 3032 may be directly formed in a side, facing the limit shaft 3012, of the rotary end, such that when the support leg 302 is in an oblique support state, the limit shaft 3012 can be clamped in the recess 3032. In this way, the contact stability between the support legs 302 and the limit shafts 3012 can be improved, and the support legs 302 are further prevented from coming loose and maintained in the support state.
