be inserted in the other leg assembly 13 that is already holding the other elongate beam 12。 It should also be understood that the system can be shipped to a retailer or consumer in a preassembled form。

  Once the elongate beams 12 are inserted into and being held by the leg assemblies 13。 the overall width of the support system 11 may be adjusted by sliding the elongate beams 12 along the lengths of each other。 The width of the support system 11 is most likely determined by the distance between the side rails 27 0f the bed frame 26。 Therefore。 It is desirable to first place the support system 11 in the center of the bed frame 26 then adjust the width of the support system 11 so that the outer ends 14 0f the elongate beams 12or brackets 25 if present。 contact or engage the side rails 27。Depending on whether brackets 25 are present, fasteners may then be used to secure the brackets 25 against the side rails 27。

   The placement of the leg assemblies 13 may be adjusted by sliding each leg assembly 13 along the length of the elongate beams 12 to the desired locations。 The placement of the leg assemblies 13 is dependent on the comfort preferences of the user(s) of the bed, the strength of the bed or frame。 the expected load on the bed。 and/or the availability

of space under meath the bed。 Once the leg assemblies 13 are in the desired locations。 the locking members may be engaged to fix the location of the leg assemblies 13 and the width of the support system 11。 If locking screws 22b are used。 this may be accomplished by rotating the screws 22b into the elongate tubes 15 through the threaded through holes 23b thereby creating a frictional engagement between the elongate beams 12 and the elongate tubes 15。

   The height of the leg structures 16 may be adjusted by moving the telescoping extensions 18 in and out of each other and/or extending or shortening the screw stem 20 0f the floor glide 19。 The height of the leg structures 16 is dependent on the distance between the support system 11

and the floor。 Once the height is adjusted such that the floor glides 19 are in contact with the floor, the leg structure's height may be fixed in place using similar locking screws 22a as used to lock the placement of the leg assemblies 13 above。

   It should be noted that the cross-rail  support system 11  can be easily disassembled as well。 To disassemble the support system 11, the user unfastens any fasteners that are secunng the brackets to the side rails and disengages the locking screws 22b in the elongate tubes 15。 after which the elongate beams 12 are free to slide out and clear of the leg assemblies 13。 The leg structures 16 can be adjusted to the shortest height position to minimize the space required to store or ship the disassembled cross-rail support system 11。

   The present invention has several advantages。 The leg assembly or assemblies 13 provide both the rigidity required to maintain the parallel alignment of the elongate beams 12 and the overall support to the mattress。 Therefore more complex or additional elements such as collars are not required。 Further。 the elongate beams 12 are inexpensive to manufacture and provide long-term durability to the support system 11。 Also。 the width of the support system 11 is adjustable allowing the support system 11 to work with any of the common size mattresses。 The placements of the leg assemblies 13 are adjustable as well。 Furthermore。 The placement of the leg assemblies 13 relative to the side rails 27 is independent from the overall width of the support system 11。 Further。 the combination of the screw stem floor glide 19 and the series of telescoping extensions 18 with locking screws 22a and the groove 24 in the outer telescoping extension allows for maximum extension or shortening of the leg structures 16。 Each leg structure 16 depending from a position closer to the outer end of its respective elongate tube 15 allows for the leg structures 16 to be set proximate the side rails 27 if required or desired。 轨交支持系统伸缩腿架英文文献和中文翻译(7):http://www.youerw.com/fanyi/lunwen_91411.html
