Detailed description of the invention
In Fig. 1, sheer pole (6) two ends are connected with right column (3) with left column (2) respectively.Protection network is made up of protection network (7), the limit, left side (9) of protection network is connected with multiple collars (8), the collar (8) is connected with guide rod (4), the collar can slide up and down along guide rod, the outer bread of the collar plastic layer, can effectively prevent that noise, the collar are provided with spring opening, facilitate installation sleeve on protection network side and guide rod.Protection network right side and left side are symmetrical.Guide rod (4), (5) are separately fixed on left and right pillar.Being connected with sheer pole below of protection network (7), top is connected with cross tube (1).The left end of cross tube in figure (1) is hinged by locking device and left column (2) after rising, the right-hand member of cross tube still in low level (not necessarily in minimum point, also may be higher than minimum point, certainly also can be driven and move because left end rises right-hand member afterwards).After cross tube right-hand member also rises, be connected with right column upper end by locking device, and drive protection network to rise together, form a facade.Unlocked device, cross tube drives protection network to fall, and facilitates people's turnover.The collar in figure can be to be also directly enclosed within on column, and column self is exactly guide rod like this, just does not need separately to have established guide rod.In addition, protection network side seams is made cloth sleeve, and cloth jacket casing replaces the collar on guide rod or column.Adopting the not benefit of sleeve is the gap that do not have more attractive in appearance.
In Fig. 2, be the locking device detail view that cross tube left end and left column are corresponding (in Fig. 1, people is that the dead ahead that stands in guardrail looks over, and Fig. 2 is that the position that stands in the left front of close left column looks over).The left end of cross tube (1) is provided with T shape and hooks (10), the large bar of T shape eave tile thin (being equivalent to a horizontal screens so T shape hooks); Left column (2) is provided with buckle (11), the opening (12) of buckle (11) is large by large change, the thin bar part that minimum position hooks than T shape is just smaller, because buckle (11) has elasticity, so T shape hooks the thin bar part of (10) and just in time can stick among buckle, thereby has realized the hinged of cross tube left end and left column.Buckle becomes from large to small large opening again and can stop cross tube left end to move upward, and the head that T shape hooks is greater than the inner ring space of buckle, so cross tube can not move left and right.In buckle, be provided with noiseproof plastics.Protection network (7) in Fig. 1 has elasticity in the vertical direction, gives downward pulling force of cross tube, so child oneself is difficult to untie the snap close of cross tube and column.Buckle in this embodiment becomes from large to small large opening again and has flexible protection network, can prevent that cross tube from moving upward, and these two features can possess simultaneously, can be also only to possess one of them.In addition, T shape in this embodiment hooks and also can change common annular hook or arc hook into, on column, corresponding buckle (11) also can change U-shaped or L-type hook into, as long as the hook of cross tube and the hook of column can stop cross tube left and right and move forward and backward just passable after being connected.In this example, can be that the sick locking other end is risen in one end the locking of first rising cross tube afterwards again; If (protection network is more loose, downward pulling force is smaller) can be also after rise simultaneously at two ends and two ends rise simultaneously, be shelved on (buckle 11 is also a saddle simultaneously) on the buckle 11 on left and right pillar, if being pushed to buckle 11, cross tube needs larger power, can successively at twice two ends, cross tube left and right be pressed into buckle so, if it is not too large that cross tube is pressed to the power needing into buckle 11, can cross tube two ends be pressed into buckle simultaneously simultaneously.
In Fig. 3, it is the detail view (in Fig. 1, people is that the dead ahead that stands in guardrail looks over, and Fig. 3 is that the position that stands in the left front of close left column looks over) of having changed the locking device of cross tube and column on the basis of first embodiment.The left end of cross tube (1) is provided with circular hook (13), the large bar of circular hook (13) head is thin, hook (14) is fixed on the upper end of left column (2), hook and column shaft have formed a downward opening limit track jointly, the circular thin bar part that hooks (13) just in time can enter from the bottom up from the under shed of hook (14), turn right again, the last descending inner bottom part that arrives hook afterwards.Meanwhile, the circular rounded nose hooking is greater than the orbit gap of hook, so move restriction cross tube left and right.Like this, cross tube left end just and hinged between column.Untiing cross tube downing track needs direction of motion of minimum conversion, so very safe for infant, infant oneself can not untie.In addition, for insurance more, can limit track descender (inner lane of hook) be designed to such an extent that have elasticity, and it be smaller just to can be compared to the circular thin bar part hooking, needs firmly could pass through, otherwise, when returning, former road also needs firmly could pass through.
In Fig. 4, it is the detail view of having changed the hook on column on the basis of second embodiment.The limit track of the hook in second embodiment only has half-turn, the limit track that hook (16) forms together with column has a whole circle many, from inner lane out, need upwards, left, downwards, to the right, upwards, left, downwards could be out, so safer.In addition, hook (16) also can be designed to circular arc.In addition, the hook in this example also can with Fig. 1 in the upper end of guide rod connect, cross tube left end is connected with guide rod, enters the limit track of hook along guide rod.Finally, adopt the fixed form of hook limit track in this example, two ends, cross tube left and right can rise simultaneously and fix, and not necessarily need first to rise one end and rise the other end again.
In Fig. 5, it is the detail view (in Fig. 1, people is that the dead ahead that stands in guardrail looks over, and Fig. 5 is that the position that stands in the left front of close left column looks over) of having changed the locking device of cross tube and column on the basis of first embodiment.The annular hook (29) that is fixed on cross tube (1) left end can be enclosed within on the U-shaped hook (28) on left column, article one, elastic rope (not drawing in figure) one end is connected with the left end of cross tube (1), the other end is connected with column lower end or sheer pole, the lowest pull that elastic rope can be mentioned between adult female to the downward pulling force size of cross tube and child can not mention or the maximum pull that upwards boosts between, cross tube left end has just been fixed on column like this, can not left back having moved up and down in front and back.In addition, the elastic rope in this example is connected with the side of protection network, and the elastic rope of tightening plays the effect that prevents that child from coming outbreak out from the gap between protection network side and column, so just not necessarily needed to arrange the guide rod that is connected with protection network side.(elastic rope has the flexible while, also has a maximum development length, is just in time also that elastic rope is when reaching maximum development length when also cross tube rises to peak.Like this, even if child pulls at protection network side, the gap between protection network side and column can not be got enough large.For example, elastic rope can form by two strands, and one has elasticity, and one does not have elasticity, by do not have flexible this one limit the maximum height that cross tube can rise.In this embodiment, if the elastic force of protection network is smaller, cross tube two ends can be risen simultaneously on the U-shaped hook that hangs over left and right pillar so; If the elasticity rate of protection network is larger, cross tube two ends be risen simultaneously on the U-shaped hook that hangs over left and right pillar, it is more difficult that practical operation is got up, and hangs other end meeting easily much so can first hang up properly one end again.The present embodiment can be also that cross tube left end or right-hand member adopt horizontal screens (for example T shape hook 10 or circular hook 13) to replace annular hook 29; First hanging up properly one end hangs the other end again and has two kinds of modes: the first: the singlehanded left end of taking is hung left end, then hangs right-hand member; The second both hands are held cross tube, and almost rise simultaneously at two ends, the high slightly point in one end, and the short slightly point in one end, first hangs up properly that higher one end, then hangs that shorter one end.U-shaped in this embodiment hooks the effect of also having played a vertical screens simultaneously.
In Fig. 6, it is the detail view (in Fig. 1, people is that the dead ahead that stands in guardrail looks over, and Fig. 6 is that the position that stands in the left front of close left column looks over) of having changed the locking device of column and cross tube left end on the basis of first embodiment.The horizontal component that is fixed on the L shaped hook (30) on cross tube (1) can just in time enter into the opening that has lid hook (31) on left column (2) from top to bottom.Thereby make cross tube left end cannot move forward and backward up and down (except the place of little opening may upwards be escaped from).For safer, can be by the left end of cross tube (1) and column lower end by an elastic rope be connected (not drawing in figure), or the protection network (7) in Fig. 1 has elasticity, give the downward pulling force of cross tube, child cannot be mentioned or upwards boost.Because guardrail height is generally high or similar than child shoulder, thus child be difficult to upwards lift, unique may be half couchant with the hands upwards front push to cross bar, but cross tube can be added a cover hook " small lid " and blocked and can not move upward.Adding a cover in this embodiment hooks and L shaped hook can be also arc.
