Abstract
The utility model relates to a ladder which can be used as a lumber rack, a strip-shaped pedal on the uppermost side of the ladder is widened into a quadrate pedal. The outer frame of the ladder and the outer frame of a supporting frame are hinged on the quadrate pedal according to definite distance. The lower part of the quadrate pedal is provided with an adjustable draw rod mechanism which enables the ladder to be unfolded or folded and to keep stable. The quantity of transverse supports on the supporting frame is equal to the quantity of strip-shaped pedals under the quadrate pedal of the ladder, and the positions of the transverse supports on the supporting frame are corresponding to the positions of the strip-shaped pedals under the quadrate pedal of the ladder. Rotatable object placing plates are arranged on the transverse supports, and when the ladder is folded, the object placing plates are bridged on the strip-shaped pedals to form a lumber rack. The whole structure can be made of materials, such as stainless steel, aluminium alloy sections, etc.
Description
The utility model relates to a kind of increase of ladder function.
Sometimes need use ladder in family life and office's operation, but therefore the existing ladder function singleness makes the people feel that it was both essential, utilization rate is not high again.
The purpose of this utility model be by the structure that changes ladder and improve its manufacture craft make ladder not the time spent close up into the Shelf for placing articles of a fineness, can be used for placing footwear, cap, the suspension foreign material are put handicraft or place kitchen tools in the kitchens.
The purpose of this utility model is achieved in that the bar shaped pedal in ladder the top is widened to certain width becomes square pedal, ladder housing and bracing frame housing are hinged on this square pedal by certain distance, increase a telescopic drag link mechanism below, stability when this mechanism should be able to guarantee the ladder use, when extending, pull bar becomes ladder, when shortening, pull bar keeps certain distance between ladder housing and the bracing frame housing, the following bar shaped pedal quantity of stull on the bracing frame and square pedal equate and the position corresponding, the glove plate that not only elasticity clamps but also can rotate is manufactured and is equipped with in stull thereon with pipe, the other end of this glove plate can be taken and be placed on the bar shaped pedal, stull can be welded or rivet with the bracing frame housing, but preferably joggle is to guarantee the attractive in appearance of profile, ladder can be used stainless steel, aluminium alloy extrusions is made, or manufacture in addition top finishing with steel, also can use engineering plastics to make.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the lateral view of ladder when closing up into Shelf for placing articles.
Fig. 2 is the elevation of ladder when closing up into Shelf for placing articles.
Fig. 3 is that ladder opens the lateral view when using.
Fig. 4, Fig. 5 show local matching relationship between the shape of individual part and part.
Fig. 6 is a drag link mechanism structural principle sketch.
From Fig. 1, Fig. 2 as can be seen, bracing frame housing (3) and ladder housing (1) are hinged on the square pedal (2), node is respectively a and b, it is each hinged junction plate (4) down, node is respectively a ', e and b ', c, two hole (15) and hole (16) that diameter is identical are arranged on the junction plate (4), they are distributed in a or b by certain angle and are the center of circle and are on the camber line of radius with the certain size, fix in milled screw (11) patchhole (16) and with knurled nut (12), two junction plates (4) are hinged together, its node is d, from Fig. 1, ladder housing (1) is 90 ° with the formed trapezoidal interior angle in ground, and the formed trapezoidal interior angle in bracing frame housing (3) and ground is between 80 ° to 90 °.
Figure 3 shows that the situation when milled screw (11) two junction plates of insertion (4) are gone up hole (15), this moment, ladder opened, according to the utility model range of application, the formed trapezoidal interior angle of ladder housing (1) and bracing frame housing (3) and ground when opening is between 55 ° to 75 °.
Fig. 4 is the lateral view of glove plate (6), Yi Bian Ω shape tongue piece (8) is arranged, it has certain elasticity, can take off from stull (7) easily, can rotate and rests on the appropriate location around stull (7) again.
Fig. 5 is the partial sectional view that shows stull (7) and bracing frame frame (3) joggle, stull (7) is manufactured with pipe, bracing frame frame (3) is a square tube, use two pulling rivets (10) to rivet from both sides, the middle storing has plug connector (9), and two pulling rivets (10) are not on the same cross section of stull (7).
Shown in Figure 6 is that ladder housing (1) and bracing frame housing (3) are hinged together by certain distance and square pedal (2), only connect at the point articulated drag link of d (14) as following by two, then the mechanism of Xing Chenging is unsettled, must increase trussed construction as shown in the figure of two diagonal members (13) formation and could keep stable, but member increases like this, not only complexity but also not attractive in appearance, two junction plates (4) respectively have two hinges with the connection of ladder housing (1) and bracing frame housing (3) on the utility model Fig. 1, its essence is drag link (14) and diagonal member (13) are merged together, node a ', b ' can regard node a as, the outer of b moves, because if make a ' and a, b ' and the b structural performance that coincides is constant, thus the shown structure of Fig. 1 its essence is as shown in Figure 6 by node a, b, c, the simplification of the leverage that d and e connected to.
Claims (4)
1, a kind of ladder that can be used as Shelf for placing articles by ladder housing (1), square pedal (2), bracing frame housing (3), junction plate (4), bar shaped pedal (5), glove plate (6), stull formations such as (7) is characterized in that: ladder housing (1), square pedal (2), bracing frame housing (3) and a pair of junction plate (4) are hinged together, its node is a, b, c, d, e, the member that is loaded with node d respectively with ladder housing (1) and bracing frame housing (3) on two nodes keep being rigidly connected.
2, it is characterized in that according to the described ladder that can be used as foreign material spare of claim 1: two hole (15) and hole (16) that diameter is identical are arranged on the junction plate (4), and two holes are distributed in node a or node b by certain angle and are the center of circle and are on the camber line of radius with the certain size.
3, it is characterized in that according to the described ladder that can be used as Shelf for placing articles of claim 1: one side elastic Ω shape tongue piece (8) of glove plate (6).
4, the ladder according to the described available Shelf for placing articles of claim 1 is characterized in that: the joggle of stull (7) two ends and bracing frame housing (3) respectively uses two pulling rivets (10), there is plug connector (9) centre, two pulling rivets (10) distribution both sides and not on the same cross section of stull (7).
