The specific embodiment

Fig. 1 shows tubulose socket 38, and it is welded on the end of the top cross member 28 of stand 30.The cross member end stretches out and exceeds vertical support member 40.The lower end of detachable vertical rod 42 can be undertaken in the socket 38 by bushing type.Fig. 2 shows detachable vertical rod 42 lower ends and is undertaken in the socket 38.Weldering system check plate 46 has stoped described end to pass completely through socket 38.

End (not shown among Fig. 2) at the stand relative with vertical support member 40 and socket 38, another vertical support member is provided with the whole body 24 (Fig. 3) that extends upward, arrival is highly joined for the safety rails that is suitable for extending with basic horizontal by the platform top that stand supports.The upper end of detachable vertical rod 42 is provided with lug 26, is used to accept the spigot of safety rails 46, so that form safety barrier in the active side of platform.Safety rails 46 also can be in a like fashion be fastened on detachable vertical rod 42 and fixing extending upward between the body 24 in the other side of same stand, to form end rails.For this purpose, lug 26 is installed in detachable vertical rod 42 and fixing extending upward on the body 24, is positioned at the essentially identical height in platform top.Safety rails 46 also is fastened on fixing extending upward between the body 24, thereby parallel and form safety barrier with respect to the other side of active side at platform.Safety rails 46 is preferably telescopic type, is used for regulating according to different stand spacing and width.They can be removed when no longer needing, and are removed gradually when for example the wall in the platform front builds up.Baseboard can be fastened in the detachable vertical rod 42 by the support (not shown) that is fit to, this support comprises the U-shaped saddle parts that for example are used to receive baseboard, with the collar that is connected with the saddle parts, detachable vertical rod 42 was passed the described collar and is threaded into before putting into socket 38.

Because SafeStand 1200 Access System further develop, have realized that the stability when its upper weight limit is used can be strengthened by the strut of introducing as shown in Figure 4 10.

For the design concept with the SafeStand system is consistent, strut has been carried out specific design with the mechanism that is connected of stand, thereby do not exist the nothing that becomes separation to connect or loosely connected parts, and the method that strut is installed on the pallet keep no technical work behavior.

Strut becomes diagonal that (also seeing Figure 13) is installed between adjacent stand; An end of strut has fixing " pin-pawl " structure 212; Whole strut all is provided out and is rotated into the position so that this end is locked in the appropriate location; Pin and rotary pawl are used to the other end 214 is locked on its stand.

Clearly show that in Fig. 5,6,9 and 10 fixing " pin-pawl " structure 212 comprises pin 216, its prebored hole 220 that is passed in the base 222 of stand is installed, and forms rotation and fix between strut and stand.The pawl 218 of structure 212 is designed especially, so that have only when strut as shown in Figure 9 tilts to specific temporary position and is in first angle with respect to base 222, pin inserts in the hole 220 of appointment in the base 222 of stand.In case the base to stand forms the pin connection, just rotates strut 210, thereby be connected with adjacent stand formation pin, be further described below with the other end 214 of strut 210.By carrying out this spinning movement, " pawl " 218 centers on and forms the joint (see figure 10) in tilt component 224 back of stand base, in case thereby strut reaches its final (second) angle with respect to the stand base, " pawl " 218 prevents that by stoping pin 216 to withdraw between the operating period at stand strut from being removed by accident from hole 220.

Be connected with the vertical vertical rod 230 formation pins that rotary pawl 228 structures can allow to pass 232 pairs of stands of preboring locating hole with the pin 226 of strut 10 the other end 214 shown in 11 at Fig. 7,8.Be bonded in the hole 232 in case sell 226, rotary pawl 228 can be rotated and around and form to engage in vertical rod 230 back, thereby rely on himself weight to be shelved on the end of pin 226, this end is outstanding from hole 232 at this.At this lay-down position as shown in figure 12, strut can not withdraw from from hole 232 and be removed by accident by pin 226.

Hole 232 can be the hole that is positioned at stand base upper end, and lockpin ventilating is crossed in the corresponding hole, bushing type top that this hole is introduced into stand, with the given described top of extension fixing.Like this, the pin 226 on the strut upper end 214 also can be used as lock pin.Yet preferably, will sell 226 joins in one of unappropriated lockhole in stand top.Alternately, pin 226 can be bonded in the special hole that is provided with in stand top or bottom, is used for the installation of strut.

Figure 13 shows a row by the interconnective stand 241,242,243,244 of strut, and the present invention is

specialized.Strut

10a, 10b, 10c, 10d become diagonal to extend between adjacent stand, and stand is unlikely to wave in the direction of connecting to stablize to cooperate formation working platform (not shown) with scaffold floor.Each stand also comprises the hound 234 of integral solder, is used to increase the lateral stability of working platform.As required, strut 10a, the 10b of intersection can be arranged between adjacent stand and be positioned at one or both sides, and perhaps independent strut can be arranged on adjoining between stand of selecting among the described stand row.Therefore, the strut use is simple, compliance is strong, firm and reliable.

The interior tubular part 80 and the outer tubular member 82 that are used for bushing type cross bar 46 have been shown among Figure 14 to be fixed together to prevent the safety feature of these two mutual slippages of parts.The inner of inner part 80 is enlarging, forms end stop neck ring 84 and has laterally outside projection 86.Correspondingly, the inner end 88 of exterior part 82 is formed the cross section that dwindles so that projection 90 laterally inwardly to be provided.

Projection

86,90 can adjoin each other to prevent that inner sleeve parts 80 from withdrawing from fully from outer tube parts 82.As shown in, neck ring 84 and to dwindle end 88 be that plastic strain end by

parts

80,82 forms is for example by crimping, forging type etc.The required distortion of parts

inner end

84,88 can produce before the outer end that spigot is coupled (e.g., welded) to each cross bar parts 80,82.The outer end of inner part 80 is at first sent into the outer end of exterior part 82 and is passed outside the exterior part inner end 88.After the leveling of any necessity is carried out in the parts outer end, spigot is connected.

What substitute that plastic strain by the cross bar parts forms is, lateral projection can produce on the element that separates, end stop/neck ring for example, and they laterally are connected on the

parts

80,82 by welding or other appropriate method.

Lateral projection

86,90 is not that the whole periphery around

parts

80,82

inner ends

84,88 is provided with, but only is arranged on one of

parts

80,82, two or three corresponding surfaces.Except shown in square or rectangular cross section, other of parts 80,82 (being preferably non-circular) cross section also is fine, some or all parts peripheries are provided with lateral projection.

Figure 15-17 shows the alternate embodiments of cross bar security feature.Elastic force load breech lock forms by pin 92, and is outstanding in the hole 94 of this pin 92 from be formed on inner sleeve parts 80.The finger presses that dependence applies by the big slightly hole 96 that is formed on outer cross bar parts 82 inner ends, pin 92 resilient bias that can overcome semielliptic spring 98 are pushed in the hole 94.Under the situation that pin is pressed into like this, thereby inner part 80 can further slide into the length of regulating cross bar 46 in the exterior part 82 as required.When parts 80 withdrawed from from parts 82 once more, because pin 92 is concordant with hole 96, it will outwards eject suddenly and be bonded in the hole 96, thereby prevents 80, the 82 mutual slippages of two cross bar parts.Therefore 96 pairs of latch pins in hole 92 form locking structure.Similar hole can be set the outer end of exterior part 82, so cross bar 46 position that can be fully retracted by kayser.In fact, corresponding interstitial hole can be set, be used for cross bar 46 kaysers at predetermined length, for example with adjacent stand between or the recommended distance that extends upward between body 24 and the relative detachable vertical rod 42 of stand be complementary.Semielliptic spring 98 can remain in the inner part 80 by welding or other suitable fasteners 100.Pin 92 can be by being formed on hole 102 riveted joints in semielliptic spring 98 other ends.But the resilient bias latch pin of other form or the elastic force load breech lock of other co-operating and locking structure will be conspicuous.
