Abstract

The utility model relates to a safe fencing rail connection structure of a trampoline. A periphery frame with a positioning spring surface is composed of frame tubes which are mutually inserted by two. The utility model is characterized in that the frame tubes are downwards and fixedly connected with a short support tube, landed with an inserting trampoline and connected with butted tube ends of support leg frames; the tube side edge of the short support tube is fixedly connected with the other short connecting tube and connected with butted tube end of an inserting safe fencing rail. Thereby, the safety fencing rail of a trampoline, etc., and the foot frame both can quickly connected with the spring surface frame, and the structure strength of the connecting position can be enhanced.

Description

Trampoline safety fences guard bar joint construction

Technical field

The utility model relates to trampoline fences guard bar, refers to a kind of bond strength that can improve fences guard bar, framework and foot rest pole especially, and makes winding operation trampoline safety fences guard bar joint construction more quickly and easily.

Background technology

Trampoline (trampoline) is provided with the spring face of being tightened by most flexible member in circular frame inside usually, and human body can stand on and carry out multiple jump action on this spring face.But it is open that traditional trampoline is, in carrying out the spring process, often cause unexpected injury, the reason that these contingencies take place mainly is to hit trampoline framework (frame) or bullet accidentally to land face, and the unexpected injury of this kind trampoline often is the child, thereby necessity of being improved is arranged.

For this reason, as United States Patent (USP) the 6th, 261,207B1 number, provide a kind of safe fences (fence) of trampoline, this fences to be formed at the above position of spring face, therefore, can prevent that the user from hitting framework or bullet and landing the unexpected injury that face caused.

Above-mentioned safe fences mainly is to be provided with the guard bar that majority is higher than spring face along the trampoline periphery, and these guard bars are wound in circumferential wire side.Because most guard bars are the upright trampoline peripheries that are located at, the mode of most convenient is with the food stand combination of itself and frame bars together.But commonly use the shortcoming that juncture exists winding inconvenience and force structure undercapacity.

Referring to Fig. 1, commonly use trampoline guard bar connecting structure, be the framework that is combined into a circle with most frame pipes 10 basically, 11 in a spring face is tightened with most flexible members 12.For making spring face 11 be positioned setting height, the bottom of frame pipe 10 must engage most foot rests 13, for the guard bar 14 and the frame pipe 10 that twine safety guard net, made up in upper and lower side with

most U-shapeds folder

15,16 with foot rest 13 joints.But the joint construction of this kind guard bar 14 forms the puzzlement in the combination operation, and because of the guard bar 14 of single trampoline has more than 8, each guard bar 14 all needs with in addition winding of

most U-shapeds folder

15,16, quite expends man-hour, cost.Simultaneously, the direction of engagement of guard bar 14 is for as shown by arrow A, but trampoline is subjected to force direction as shown by arrow B when spring, and its force way is very undesirable, and structural strength is obviously not enough, rocks or makes connected structure impaired and be easy to generate.

Summary of the invention

The purpose of this utility model is to provide a kind of trampoline safety fences guard bar joint construction, and it can effectively improve the bond strength of trampoline safety fences guard bar, and makes its assembling operation more quick and convenient.

For reaching above-mentioned purpose, a kind of trampoline safety fences guard bar joint construction of the present utility model, constitute the peripheral frame of a location spring face by the frame pipe of pegging graft each other in twos, it is characterized in that: the affixed downwards weak point arm of above-mentioned frame pipe lands with the grafting trampoline and the pipe end that connects of support foot rest is connected, and affixed another nipple of above-mentioned short arm side is connected with the pipe end that connects of the safe fences guard bar of pegging graft.Wherein,

Described affixed short arm and nipple are the hollow tube of deciding diameter, and the pipe end that connects of foot rest and guard bar is then to dwindle pipe end and its grafting in footpath.

Described short arm and frame pipe and and nipple between all fixing to weld.

The utility model can make trampoline foot rest and guard bar more quick and convenient with engaging of trampoline framework, so exempt the loaded down with trivial details assembling operation program of U-shaped folder up and down of using, and can reduce cost, simultaneously, the stress point of trampoline junction when spring is that the integral type welding is fixing, and its structural strength is enhanced significantly.

The specific embodiment

Referring to Fig. 2,3, be the utility model one preferred embodiment, a kind of trampoline safety fences guard bar joint construction, comprise in order to be combined into a plurality of frame pipes of circular trampoline framework, with any two

frame pipes

20,30 is example, wherein any frame pipe 20 or frame pipe 30 extends short arms 40 downwards, basically,

frame pipe

20 or 30 and this weak point arm 40 can weld and be fixed into integral type.These weak point arm 40 1 sides are another nipple 50 of solid welding and constitute the guard bar and the clevis joint of an enhanced type jointly again.

This weak point arm 40 and nipple 50 are the hollow tube of setting diameter, and safe fences guard bar 60 and foot rest 70 are equipped with the

adapter end

61,71 that dwindles the footpath, guard bar 60 and foot rest 70 all can be pegged graft respectively with its

adapter end

61,71 that dwindles the footpath be combined in short arm 40 and the nipple 50.

Simultaneously, in the present embodiment, in order to engage the nipple 50 of guard bar 60, can be preset with path lateral strut 51 near the place, bottom, to twine positioning security fences protecting wire net at it.

Referring to Fig. 4,5, the upright guard bar 60 that is made as certain height can directly be taken over its bottom end 61 insertions and be incorporated in the nipple 50 that side establishes.And the foot rest 70 (being illustrated as U-shaped) that lands of whole trampoline then should make its adapter end 71 up, is plugged in the short arm 40 (joining shown in Figure 4) that is extended by frame pipe 20 downwards.This guard bar that has engaged 60 can highly twine and is positioned at required safe fences protecting wire net 80 (joining shown in Figure 5) according to it, makes the positioning rope 81 of this protecting wire net 80 can be sleeved on the path lateral strut 51 of nipple 50.

The above only is the utility model one preferred embodiment; be not to limit practical range of the present utility model with this; allly be familiar with this skill personage; do not breaking away under the utility model spirit and the feature; various distortion and the modification done all should be covered by within the patent protection category that the utility model claims are defined.
