Benefits of technology

[0005]The main member is formed as a main tube or main pipe and supporting member is formed as a supporting tube or supporting tube is improved. The trampoline frame has a main pipe and a support pipe. The main pipe has a straight line weld seam. The support pipe supports the main pipe. The main pipe injunction with the support pipe has a concave connection. The main tube weld seam is on the bottom facing the concave portion.

Problems solved by technology

Furthermore, a trampoline frame receives a substantial amount of vibration on the Main tubes which have a propensity to cause separation and cracking of the welding seams.

Embodiment Construction

[0013]The figures are explained as follows. According to FIGS. 1, 2, 3 of the present invention, the main portion is a welding together of the main tube 1 and the support tube 2. The main tube 1 has a straight welded seam 11 formed on a bottom edge. The main tube 1 is placed on the support tube 2 so that the support tube 2 has an upper end of the support tube forming a concave saddle for seating the bottom part of the main tube 1 with an outer surface forming a concave depression 21 in the shape of an arc scoop channel. The support tube is welded to the main tube.

[0014]According to FIGS. 4, 5, 6 in addition to the above embodiment there is added a reinforcing plate 3 welded over main tube 1 and support tube 2's weld seam junction. The reinforcing plate is welded at the connection between main tube 1 and support tube 2.

[0015]To ensure that the reinforcing piece and main tube 1 and support tube 2 has good coordination, the reinforcing plate 3 top portion 31 has a concave curvature con...

Abstract

The present invention is in the field of sports equipment, more specifically, relating to a trampoline frame connection structure. The trampoline frame has a main pipe and a support pipe. The main pipe has a straight line weld seam. The support pipe supports the main pipe. The main pipe junction with the support pipe has a concave connection. The main tube weld seam is on the bottom facing the concave portion. This practical new design features an improved welding configuration that has a low budget and high-efficiency connection. The weld seam on the bottom decreases shock to the weld seam and also prevents interference between the connecting hole on the main pipe and weld seam. Finally, this invention uses a weld seam strengthening plate device.

Description

[0001]This application claims foreign priority from Chinese national application for Trampoline Frame Welding Configuration having application number 200820049070.6 filed Jun. 12, 2008.FIELD OF THE INVENTION[0002]The present utility invention relates to trampoline frame structures.DISCUSSION OF RELATED ART[0003]Trampolines typically have tubular frames which are typically made of several main members arranged in a circle and supporting members supporting the main members. A trampoline bed is secured to the frame. Previously, the bed support was directly welded to main members formed as main tubes. More recently, to improve the Main tubes and to make them cheaper, the main tubes have been constructed of welded sheets. Because the main tube is modularly fashioned, it must connect with other parts and sometimes hole connections are used. When there are hole connections, the hole must not affect the seam so that the main pipe is weakened. Furthermore, a trampoline frame receives a subst...
