Description

Trampoline rail system

Technical Field

The utility model relates to a trampoline rail and trampoline bed system's field.

Background

More recently, trampoline rails and trampoline spring covers have become increasingly popular. Trampoline spring covers have been formed as mats or sheets to cover trampoline springs. Trampoline rails typically include a net.

Various trampoline rail and mat systems are described in the U.S. patent. For example, Sidlinger, published on 23.10.1973, U.S. Pat. No.3,767,009 entitled "Trampoline Support And shock Means," discloses a Trampoline spring cover, the disclosure of which is incorporated herein by reference. U.S. patent No.6,193,632 entitled "Trampoline Pad Assembly" issued by Steger at 27.2.2001, the disclosure of which is incorporated herein by reference, proposes a variable thickness Trampoline Pad Assembly. U.S. patent No.6,017,292 entitled "Method And Apparatus For Attaching a Trampoline Pad" published by inventor Gift 4/7 in 1998 proposes a Method of Attaching a mat to a Trampoline frame using tabs.

Other trampoline mat systems allow for different configurations of mat and spring structures. Us patent No.3,677,368 entitled "Trampoline" issued by inventor Green at 18.7.1972 proposes a Trampoline frame with a spring suspension structure. A user landing on a trampoline mat attached to a trampoline frame having a spring suspension structure will benefit from the downward bending movement of the frame on a portion of the frame in response to an applied downward force. U.S. patent No.7,494,144 entitled "Adjustable Trampoline Pad System" published by inventor Samuel Chen at 24.2.2009, proposes a Trampoline mat System that can be reconfigured in a modular fashion. While conventional foam blocks have met with some success, they can still be improved by changing the construction.

U.S. patent 6,261,207 entitled "Trampoline or the Likewith Enclosure" issued by inventor public on 7/17 of 2001 describes a Trampoline having a rail extending above a rebounding surface. The pen is supported by a vertical, flexible, independent rod system, the tops of which are connected by flexible straps. When the fence is impacted, the rods absorb any impact force along the fence by bending inward, the disclosure of which is incorporated herein by reference.

U.S. patent publication No.20140228176 entitled "Trampoline" issued by inventor Miller at 8/14 of 2014 describes a Trampoline rail with vertical support bars "bent outwardly from the frame and upwardly from the frame toward the mat. "these rods support" at least one net "attached to the rods by a plurality of sheaths on the net, and the rods may be inserted into the net, the disclosure of which is incorporated herein by application.

In U.S. patent No.5399132A entitled "Safety Enclosure for Trampoline" published on 21.3.1995, the inventor Bailey proposed a rail apparatus having a plurality of panel assemblies surrounding a Trampoline. Each panel assembly is comprised of two vertical members and a horizontal member connecting the top ends of the two vertical members. A plurality of vertical and horizontal cords attached to each panel assembly intersect the planar cross formed by the vertical and horizontal members to provide a barrier to prevent a user from falling from the trampoline, the disclosure of which is incorporated herein by reference.

Inventor Colling, in us patent No.7,481,740 entitled "Trampoline accesses" published on 27.1.2009, describes a deflecting net connected to a U-shaped rod structure and attached to the rebounding mat of a Trampoline. The net is attached to the rod structure around the periphery of the trampoline by knots, adhesives, fasteners, and by passing the rods through openings in the flexible material of the net, or any other attachment method known in the art, the disclosure of which is incorporated herein by application.

One method for attaching a Trampoline rail to a Trampoline frame is described in U.S. patent No.7758471 entitled "Trampoline encapsulation to Trampoline Mat" issued by the inventor Nelson at 20, 2010. Grommets dedicated to receiving spring attachment members (e.g., D-rings, V-rings, etc.) are included at or near the bottom edge of the fence including the flexible wall. When each trampoline spring attachment member passes through the grommet, the rail will be securely attached to the trampoline. The top end of the rail is further supported by attaching the rail to a U-shaped bar structure around the periphery of the trampoline, the disclosure of which is incorporated herein by reference.

In U.S. patent No.9,084,908 entitled "Trampoline baskethall Goal" published on 21/7/2015, inventor Chen used an upper fence loop to hang its fence net around the Trampoline. The upper enclosure ring is supported by enclosure rails surrounding the trampoline. The upper fence ring is attached at or near the top end of the fence by a fence rod connection cap having a slotted hook receptacle to receive the fence ring. A sheath at the top edge of the fence net slides around the fence ring to suspend the net, the disclosure of which is incorporated herein by reference.

U.S. patent No.8,012,066 entitled "Wire Trampoline Enclosure" issued by inventor Hsiang on 6/9/2011 details a Trampoline rail that includes a non-flexible Wire loop having a plurality of connectors attached to the loop and a plurality of support rods. The support rods are bent inwardly at their top ends. A wire slot in the support rod receives a wire loop, hanging it above the trampoline. The fencing wire is suspended from a wire loop at the top end of the fencing wire, the disclosure of which is incorporated herein by reference.

In U.S. patent No.5,941,798 entitled Safety Net for simulations, published 24.8.1999, inventor Coan described a trampoline Net assembly that encloses a trampoline frame and is supported by a plurality of support members arranged such that the Safety Net is configured in an inverted truncated configuration. Furthermore, the bottom edge of the mesh is equipped with a mat that extends along the net tire length of the bottom edge. In its preferred embodiment, the pad has a "conical inner periphery" (see fig. 5), the disclosure of which is incorporated herein by reference.

His safety mat for a Trampoline is described and illustrated in U.S. patent No.8,790,221 entitled "Trampoline" published by schafer on 7/29 2014. As shown in fig. 6, the pad covers the underlying spring. The lower part of the safety net surrounding the reflecting surface is sewn to a right-angled triangular shaped member, wherein one edge of each triangle is formed by this member, while the other edge of each triangle at right angles to the front edge covers the pad, the disclosure of which is incorporated herein by reference.

In us patent No.9,545,532 entitled "Trampoline access Attachment System" published on 1/17 2017, the inventor Miller described that an edge protection mat (see fig. 4) mounted on top of and extending over the edge of the Trampoline could be added to cover the edge of the mat and any rigid items on or near the mat edge. The mat eliminates any gap between the rebounding surface and the trampoline frame, thereby preventing injury to the user, the disclosure of which is incorporated herein by reference.

Detailed Description

Typically, a trampoline has a trampoline 32 suspended on springs 31. A spring 31 is attached between the trampoline frame horizontal portion 30 and the trampoline 32. A spring inside connector 33 connects the spring 31 to the trampoline 32. An outer spring connector 34 connects the spring 31 to the trampoline frame horizontal portion 30. The spring outside attachment and the spring inside attachment may be formed as hooks formed on both ends of the spring 31. The hooked end may extend into the trampoline frame hollow 30, which may be formed as a tube.

The trampoline feet 20 can be formed as a continuous edge, a U-shaped member, or a simple post. The trampoline foot 20 shown in the drawings has a plurality of portions including a foot angled portion 21 extending at an angle from a foot vertical portion 22. The leg vertical portion 22 is connected to the leg horizontal portion 23 at a leg base connection 26 to define a U-shaped leg member. The trampoline foot 20 is connected to the trampoline frame horizontal portion 30 at the foot frame connector 25. The trampoline feet 20 extend slightly beyond the periphery of the horizontal portion 30 of the trampoline frame.

The rail 40 is connected to the trampoline frame horizontal portion 30. The enclosure 40 has an enclosure net 50 to keep the user within the jumping area of the trampoline 32. The trampoline 32 has a periphery attached to the springs. The periphery of the trampoline is covered by a mat system 60.

The fence 40 comprises a fence rod 41, the fence rod 41 being connected to a fence upper support 42 via a fence upper connection 43. The rail upper connector preferably has a rail connector receiver 44, and the rail connector receiver 44 can be formed as a receptacle for receiving the tubular end of the rail upper support 42. The rail 41 has a rail lower connector 45 that connects the rail 41 to the trampoline frame horizontal portion 30.

A fence net upper connector 54 connects the fence net 52 to the fence upper support 42. The fencing net upper connector 54 may be formed as a sheath formed over the fencing net 50. The sheath may form a hollow elongated cavity that receives the fence net upper support. The fence net upper connector 54 can also be sewn to the fence upper support 42. The fence net may preferably be a twin net with a larger mesh outer net and a smaller mesh inner net. The outer mesh may be connected to the inner mesh with a fabric loop or interwoven therewith. The outer mesh preferably has a thicker braid and has a stronger material capable of carrying a greater linear tension, while the inner mesh preferably has a thinner braid capable of preventing finger pinching.

Preferably, the fence net 50 comprises an outer fence net 52 and an inner fence net 51. The outer barrier net 52 has a different woven structure than the inner barrier net 51. Preferably, the outer fence net 52 is connected to the inner fence net 51 at a net-to-net interface 56. The net-to-net interface 56 is formed as a band that wraps around the circumference of the pen 40. The inner fence net may have mesh openings 59 which may be less than 1cm and the outer fence net may have mesh openings 59 which may be greater than 1 cm.

The zipper 53 is preferably formed to penetrate through two layers, i.e., the outer barrier net 52 and the inner barrier net 51. The zipper 53 is sewn to both the outer barrier net 52 and the inner barrier net 51. The zipper 53 has a zipper guide tape 58. Zipper guide strips 58 are also sewn to the inner and

outer barrier webs

51, 52. A zipper guide 58 may also be sewn to the web-to-web interface 56. A set of snaps may supplement or replace the zipper 53. The hasp 57 can be provided at the bottom or lower edge of the fence net 50 or at the middle of the fence net 50.

The user can use the step 48 when entering the zippered opening of the railing 40. The step 48 is formed on the recess 47. The step 48 may be made of a thick wood board or a thick plastic sheet such as high density polyethylene. The step 48 may also be made of wood or steel, but is preferably a thick plastic sheet. When made as a plank, the step 48 preferably covers the spring to allow safe access by the user. The plank may be encapsulated in a foam pad and placed inside a fabric cover.

The recess may be supported by the step side pad 66 and the wall pad 62. The recess is formed between a pair of stepped side pads 66 which are triangular side pads. The fence net is preferably connected to the net lower attachment member 55 at the mat system apex 67 or at the lower portion near the spring inboard attachment member 33.

The pad system 60 may be filled or simply a sheet. The mattress system 60 includes a wall mattress 62 that extends upwardly from the bed 32. Wall pad 62 has additional support of support pad 61. Support pad 61 has a diameter greater than the diameter of wall pad 62 and is angled toward wall pad 62 such that support pad 61 is connected to wall pad 62 at pad system apex 67. The pad system apex 67 connects the support pad 61 with the wall pad 62 to form a pad frame. The cushion frame is formed of a cushion material, which may be foam or a sheet, or a combination of both such as a laminate structure. The foam is preferably covered by a foil. The support pad 61 and the wall pad 62 have a pad system hollow portion 68 formed between the support pad 61 and the wall pad 62. The cushion system hollow 68 has a space for receiving the inflatable ring 63, which may be formed as a balloon that may be made in sections and inserted into the cushion system hollow 68. The pad system hollow portion 68 is generally triangular in cross-section, and the pad system 60 also has a generally triangular cross-section.

When the user lands on the pad system, the user touches the pad system vertex 67. The mat system apex 67 resiliently supports the user to push the user away from the trampoline frame horizontal portion 30. The lower ends of the support pads 61 and the lower ends of the wall pads 62 are preferably connected together by a leaf spring cover 64 or a pad spring cover 63.

The triangular cross-section of the pad system 60 produces a variety of geometric configurations having determinable measurements including a vertex 71. Apex angle 71 is the angle between the surface of support pad 61 and wall pad 62. The inner corner 72 is the angle between the gasket spring cover 63 and the wall pad 62. Outer corner 73 is the angle between support pad 61 and padded spring cover 63. The wall mat inner surface 74 is the inner surface of the wall mat that faces the trampoline 32. Wall pad outer surface 75 is the outer surface of the wall pad that faces support pad 61. Apex corners 71 are disposed between wall pad outer surface 75 and the inner surface of support pad 61. The apex angle 71 is preferably acute and preferably less than 60. When the spring 31 is not in the extended position but in the neutral rest position, the wall pad 62 is longer in height than the spring 31.

The wall pad preferably includes a lower extension that forms a pad system spring recess 65 that fits over at least a portion of the spring 31. The pad system spring recess 65 conforms to the contour of the spring 31.

The trampoline mat is formed from a pair of annular flexible foam members. Each flexible foam member is attached to each other at a folding joint. The foam member may be encapsulated within a fabric shell. Thus, when a user lands on the mat system and contacts the mat system apex 67, the mat system apex 67 folds over the springs 31 and the trampoline horizontal frame tubes 30. The folding action is resistant because it requires the entire mattress system to deform. Also, the folding action optionally compresses the inflatable member 69.

Various special visual effects may be achieved by different net weaves, for example by having different coloured nets, or by using a luminescent paint to paint one of the nets. The web may also have a visually coordinated overlay to achieve a plating design.

The inner mesh 120 may be positioned higher than the outer mesh 130. The inner mesh 120 is suspended from a fence top support 121. The rail top support may be a rope or wire, such as a metal flexible member. Inner mesh 120 preferably has a gap between it and outer mesh 130. The gap is preferably sufficient and the user may be initially held by the inner mesh 120 and then by the outer mesh 130 such that the pair of meshes have a two-stage activity such that they act as a pair of springs for holding the user in the boundary region.

The rail 124 has a rail upper connector 122 where the rail 124 connects to the rail top support 121. The railing 124 also has a railing outside the upper net connection 123. The railing outside the upper net connection 123 is where the outer net attaches to the railing. Attachment may be by straps or by hardware connections. The railing outside the upper net attachment 123 is lower than the railing upper attachment 122. The rail outside the upper net connection 123 is located distal to the rail upper connection 122.

The inner mesh top webbing strip 126 may connect the fence top support 121 to the inner mesh upper connector 128, so the inner mesh top webbing strip 126 has a circumferential profile for reinforcing the connection between the inner mesh upper connector 128 and the fence top support 121. The inner mesh top webbing strip 126 may be a strip of fabric, with a fabric panel overlying and parallel to the fence top support 121. The inner mesh top webbing strip 126 is preferably flat and sewn into the inner mesh 120 proximate the inner mesh upper links 128. The inner mesh top webbing strips 126 reinforce the stresses and distribute the stresses evenly to prevent tangential tearing.

A rail top webbing strip 127 is attached between the rail 124 and the inner web 120, similar to a reinforcing fabric strip, for evenly distributing stress to prevent tearing. Similar to the inner mesh top webbing strip 126, the rail top webbing strip 127 is also triangular arcuate. The edge of the top band of railing strips 126 and the edge of top band of railing strips 127 along the inner web upper connector 128 may overlap each other and be connected to each other along at least a portion of their lengths.

The inner mesh profile 129 may be formed to connect the outer mesh to the bed connector 135 or the inner mesh to the bed connector 134. In either case, inner mesh profile 129 curves inward so that the user can encounter resistance to flexibility earlier than a straight inner mesh profile. The outer mesh 130 is similarly curved inwardly to have a concave profile. Inner mesh profile 1129 and outer mesh profile 130 may also be matched to have similar concave curves for aesthetics and functionality.

The pair of nets with the webbing strips can catch the user soft and preferably more securely. The frame can also be made more flexible, preferably safer, to supplement the mesh. The frame may have modified frame feet, and the modified frame feet may be connected together at foot engagement straps 150. The foot-engaging strip 150 is preferably manufactured as a perforated bent metal sheet that has been formed into a three-dimensional shape from a two-dimensional planar shape.

The frame legs 131 are preferably U-shaped to support the bed 132. A spring cover 133 overlies the bed 132. An inner web-to-bed connector is provided along the inner periphery of the spring cover 133. The foot base 140 is a part of the frame foot 131 and supports the frame foot 131 on the ground such as concrete or dust. The small foot base 140 may form a tubular member that is curved upward in the middle and curved downward on the left and right sides of the small foot base 140. The small foot base connector 141 is preferably formed as a swage taper or socket having a different diameter such that the small foot base connector 141 connects to the vertical foot section lower socket connector 146.

The vertical leg portion 143 has a vertical leg portion lower connector 146 and a vertical leg portion upper socket connector 145. Adjacent horizontal leg portions 147 are adjacent to horizontal leg portions 144. A series of horizontal leg portions are formed in arcs that join together to form a complete circle or other shape. Adjacent horizontal leg portions 147 are adapted to be mounted to the leg engaging strip 150. Similarly, the horizontal leg portion 144 is also adapted to be mounted to the leg engaging strap 150. The adjacent horizontal leg portion 147 has a reduced diameter portion that partially fits within the horizontal leg portion 144. The reduced diameter portion of the adjacent horizontal leg portion 147 also fits into the leg engaging strip 150. The foot frame connector 25 may be formed as a foot engagement strip 150. The foot engagement strip 150 has adjacent foot engagement strips 170 on opposite ends of the horizontal foot portion 144. The horizontal leg portion 144 fits into the leg engaging strip 150 and the adjacent leg engaging strip 170.

The foot-engaging strip 150 generally has a front panel 151 and a rear panel 152. The front panel 151 and the rear panel 152 form a front half of the tube and a rear half of the tube. A panel gap 153 is formed between the front panel 151 and the rear panel 152. The front panel 151 and the rear panel 152 are opposite ends of a steel metal plate that has been bent into shape. The panel gap 153 may be narrow or wide. When the panel gap is narrow it may abut but not connect, if wider than the panel gap, the gap may be e.g. 1mm or 2 mm. The front panel 151 transitions to a front shoulder adapter 154. Front shoulder adapter 154 is the transition shape between front horizontal tube receiver 155 and front panel 151. The front panel 151 has a tubular profile in the vertical direction and the front horizontal tube receiver 155 has a tubular profile in the horizontal direction. Similarly, the rear horizontal tube receiver 156 has a horizontal tubular profile that is perpendicular to the vertical tubular profile of the rear panel 152. Similarly, the rear panel 152 transitions to the rear horizontal tube receiver 156 at the rear shoulder adapter 159.

Between the front horizontal tube receiver 155 and the rear horizontal tube receiver 156 there is a top plate 160. The top plate 160 forms a top planar region 157. A shoulder 158 is formed between the inboard shoulder width 163 and the outboard shoulder width 165. The shoulder 158 faces downward and abuts the upper edge of the vertical leg upper socket connector 145 of the vertical leg portion 143. The upper edge faces generally upward and the shoulder 158 faces generally downward so that they contact each other. The shoulder 158 has a rear shoulder adapter 159 and a front shoulder adapter 154. The pair of shoulder adapters are shaped to define a downwardly facing shoulder 158.

The top plate 160 has a top plate thickness 161. The shoulder 158 has an inboard shoulder width 163 and an outboard shoulder width 165. The front and rear panels each have a foot engagement strap attachable opening 171 and a foot engagement strap connector screw opening 172. The foot-engaging strap connector screw opening 172 is located below the shoulder and a distance from the shoulder screw opening shoulder distance 173. The foot-engaging strap connector screw opening 172 is above the foot-engaging strap connector bolt opening 171. The foot-engaging strap connector screw opening 172 defines the through-bolt axis 164 into which the bolt is inserted.

An interior of the receptacle is formed between the front level vial receiver 155 and the rear level vial receiver 156. The pair of receptacle receptacles have a receptacle inner side upper radius 166. The tube receiver also has a socket inside lower radius 167. The horizontal tube receiver receptacle width 162 is sized to receive two members that are horizontal. The horizontal tube receiver receptacle width 168 is also sized to receive a horizontal tube member. A first horizontal tube member is adapted to fit into the receptacle and has a reduced size portion with an outer width adapted to fit within the width of the horizontal tube receiver receptacle. Then, a second horizontal pipe member, which is an adjacent horizontal member, is fitted into the socket of the first horizontal pipe member. Thus, the interior of the socket is formed to receive the outer tubular member of the horizontal tubular member, which is an intermediate tubular member that in turn receives the inner tubular member. Thus, the socket forms a three-layer connection. No bolts pass along the horizontal pipe receiver receptacle width 168 to allow a flexible connection between the three tubular members.

As shown in fig. 15 to 16, the inner mat 80 may be aligned with an interior corner of the trampoline where the double trampoline net meets the trampoline. The inner mat has an inner mat slope 81, and when a user bounces on the trampoline, the inner mat slope 81 faces the user. The inner mat 80, which is triangular in shape, prevents the user from hitting the trampoline frame when falling.
