Abstract
A connector for trampoline safety fence post includes a short supporting tube and a short connecting tube fixedly and parallelly connected to one side of the supporting tube. The supporting tube is fixedly connected at an upper end to a lower side of one of many frame pipes forming a trampoline frame, so that a corresponding tube-connecting end of one trampoline supporting leg may be upward inserted into a lower open end of the supporting tube, and a tube-connecting end of the safety fence poet may be downward inserted into an upper open end of the connecting tube. The connectors enable the trampoline supporting legs and the safety fence posts to be quickly connected to the frame supporting a jumping bed of the trampoline and ensure an enhanced structural strength at the connected points.
Description
- The present invention relates to safety fence posts for a trampoline, and more particularly to a connector enabling quick and structurally enhanced connection of safety fence posts to supporting legs and frame of a trampoline.
- A trampoline typically includes a jumping bed connected to and tightly stretched over a round frame via a plurality of elastic elements extended between the jumping bed and the frame. A user may stand on the jumping bed to do various jumping movements. Conventional trampolines have an open jumping bed that tends to cause accidents when a user jumps thereon and carelessly collides against the frame or falls to the ground on which the trampoline is positioned. Such accidents often happen particular when the user is a child. It is necessary to improve the conventional trampoline having an open jumping bed.
- U.S. Pat. No. 6,261, 207 B1 discloses a trampoline safety fence for enclosing a space immediately above the jumping bed,80 as to protect a user from any unexpected injury caused by colliding against the frame or falling to the ground outside the jumping bed.
- The trampoline safety fence disclosed in U.S. Pat. No. 6,261,207 B1 mainly includes a plurality of poets spaced along an outer periphery of the trampoline at a position higher than the jumping bed. A protective net is supported on these posts to circumferentially enclose the trampoline. The most convenient way to vertically erect the posts along the outer periphery of the trampoline is to bind them to supporting legs and the frame of the trampoline. However, a conventional manner of binding the safety fence poets to the trampoline legs requires a lot of labors and time, and has the disadvantage of insufficient structural and bearing strength.
- FIG. 1 shows a conventional manner of connecting a safety fence post to the trampoline frame and leg. Basically, the trampoline frame is a round frame formed from a plurality of sequentially connected
frame pipes 10. Ajumping bed 11 is connected to and tightly stretched over theframe pipes 10 via a plurality ofelastic elements 12. To set thejumping bed 11 to a predetermined height, a plurality of supportinglegs 13 must be connected to a lower side of theframe pipes 10. Each safety fence post 14 for supporting the protective net is connected to theframe pipe 10 and the supportingleg 13 by means of upper and lower U-shaped fasteningmembers safety fence posts 14 for each trampoline, and eachpost 14 requires multipleU-shaped fastening members frame pipe 10 and the supportingleg 13, a lot of time and labors are needed to complete such connection. Meanwhile, thesafety fence post 14 is connected to theframe pipe 10 and the supportingleg 13 in a horizontal direction as indicated by the arrow A, while the trampoline is subject to a jumping force in a vertical direction as indicated by the arrow B. As a result, the fasteningmembers - A primary object of the present invention is to provide a connector for trampoline safety fence post to enable quick, convenient, and effectively enhanced connection of the safety fence post to trampoline frame and supporting legs.
- To achieve the above object, the connector for trampoline safety fence post according to the present invention includes a short supporting tube fixedly connected to and downward extended from a lower side of one of many frame pipes of a trampoline frame for a corresponding tube-connecting end of a supporting leg of the trampoline to insert into a lower open end of the supporting tube, and a short connecting tube fixedly parallelly connected to one side of the short supporting tube for a corresponding tube-connecting end of the safety fence post to insert into an upper open end of the connecting tube.
- Both the supporting and the connecting tube are hollow tubes having a predetermined diameter The tube-connecting ends of the supporting legs and the safety fence posts are diameter-reduced end adapted to tightly fit in the supporting and the connecting tube, respectively.
- The supporting tube is welded to the connecting tube and the frame pipe.
- The connector of the present invention enables quicker and more convenient connection of the safety fence posts to the trampoline frame and supporting legs. The troublesome and time-consuming connection of the safety fence posts to the trampoline frame pipes and supporting legs using the upper and lower U-shaped fastening members can therefore be saved to reduce the manufacturing cost of the trampoline. Moreover, since points of load at connecting areas of the connector are welded, the connector has apparently enhanced structural strength.
- The structure and the technical means adopted by the present invention to achieve the above and other objects can be beat understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
- FIG. 1 is a fragmentary perspective view showing a conventional manner of connecting a safety fence post to a trampoline;
- FIG. 2 is an assembled perspective view of a connector for trampoline safety fence post according to a preferred embodiment of the present invention;
- FIG. 3 is an exploded perspective view of FIG. 2;
- FIG. 4 is a fragmentary perspective view showing the use of the connector of the present invention to connect a safety fence post to a trampoline; and
- FIG. 5 shows a protective net is connected to the trampoline safety fence post of FIG. 4.
- Please refer to FIGS. 2 and 3 that are fragmentary assembled and exploded perspective views, respectively, of a connector for trampoline safety fence post according to a preferred embodiment of the present invention. As shown, the connector is a strengthened member for connecting a
safety fence post 60 to a frame pipe and supportingleg 70 of a trampoline and is formed from a short supportingtube 40 and ashort connecting tube 50 welded to one side of the short supportingtube 40. A trampoline typically includes a plurality of frame pipes that are sequentially connected to form, for example, a round-shaped trampoline frame. In the illustrated drawings, two serially connectedframe pipes tube 40 is welded to a lower side of a frame pipe, say, theframe pipe 20, to downward project from theframe pipe 20. - Both the supporting
tube 40 and the connectingtube 50 are hollow tubes having a predetermined diameter. Thesafety fence post 60 and the supportingleg 70 have diameter-reduced tube-connectingends tube 50 and a lower open end of the supportingtube 40, respectively. - Meanwhile, in the illustrated embodiment, the connecting
tube 50 for connecting to thesafety fence post 60 is provided on an outer wall surface near a lower end thereof with a radially projectedbar 51 having a predetermined small diameter. - Please refer to FIGS. 4 and 5. The
safety fence post 60 having a predetermined specific height is directly connected to the connectingtube 50 by downward inserting the diameter-reduced tube-connectingend 61 into the upper open end of theconnecting tube 50, and the supportingleg 70, which is a U-shaped member with two upward tube-connectingends 71 in the illustrated drawings, is connected to supportingtubes 40 of two of the connectors of the present invention by upward inserting the diameter-reduced tube-connectingends 71 into lower open ends of the two supportingtubes 40 that downward extend from theframe tubes 20, as shown in FIG. 4. After allsafety fence posts 60 for the trampoline are properly connected to the frame and the supportinglegs 70 of the trampoline via the connectors of the present invention, aprotective net 80 is firmly connected to thesafety fence posts 60 at predetermined height withtying cords 81 provided on theprotective net 80 being tightened to the mall-diameterradial bars 51 provided at lower ends of the connectingtubes 50. - The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications in the described embodiment can be carried out without departing from the scope and the spirit of the invention as defined by the appended claims.
