Description of drawings: Fig. 1: door hinge one side drawing in side sectional elevation when door is opened.Fig. 2: door hinge one side drawing in side sectional elevation when door closes.The A portion of Fig. 3: Fig. 1 amplifies.The B of Fig. 4: Fig. 1 is to view.Fig. 5: a kind of elevation of backplate.The C-C sectional drawing of Fig. 6: Fig. 5.Fig. 7: a kind of drawing in side sectional elevation of backplate.Fig. 8: a kind of drawing in side sectional elevation of backplate.
Contrast description of drawings embodiment.As depicted in figs. 1 and 2, the crack between a door and its frame backplate is made up of the rectangular plate (1,2,3,4) of mutual connection, the rectangular plate on both sides (1,4) is separately fixed on the door (5) and doorframe (6) of door leaf swinging axle one side, and available screw (7) or nail are fixed, and also can gluingly fix.Hinge (8) connects door and doorframe.The crack between a door and its frame backplate generally can be installed in student portion, its height with the child beyond reach the crack between a door and its frame that exposes of top be advisable.Also can install for attractive in appearance along the whole piece crack between a door and its frame.The condition of determining the width L of two the rectangular plates (2,3) in the middle of the backplate is that two rectangular plates (2,3) protrude (as shown in Figure 1) to crack between a door and its frame place side in the time of should guaranteeing that door leaf leaves to maximum position, in order to avoid backplate is entered seam the inside and influence is closed the door to the arrow E direction is folding at closing time.Backplate can be made with the extrusion molding of plastics disposable integral, and material can be selected polypropylene for use.Thin place between each rectangular plate forms the polypropylene plastics hinge connection that disposable integral is extruded.Fig. 3 is the partial enlarged drawing at polypropylene plastics hinge place.Plastic hinge connects to be made between each rectangular plate and can swing, and (as shown in Figure 1) opened in each plate tensible when door was opened, and each plate can fold (as shown in Figure 2) when door closed.Shown in Fig. 1,3,4,, can open some strias or aperture in hinge connection for further reducing the elasticity of plastic hinge.The influence that such backplate is split, closed the door is littler.
As illustrated in Figures 5 and 6, can interconnect with hinge between the backplate.Make polylith flap (9,10,11,12) with plastics or metal sheet roof covering, they are interconnected into four the rectangular plates that can swing with thin axle (13).
As shown in Figure 7, rectangular plate (14,15) (plastic plate, hardboard, water plate, aluminium sheet etc.) is contained in flexible thing (as cloth, artificial leather, nylon taffeta, plastic sheeting etc.) and stitches in four the rectangular bags (16) that link together side by side mutually of (or hot pressing) one-tenth.Elasticity is very little between each plate of the crack between a door and its frame backplate of this structure, and is convenient to small lot batch manufacture.
The simple guard board structure of another kind of method for making as shown in Figure 8, rectangular plate (17,18) is bonded on the flexible thing (19) and couples together.Flexible thing between the rectangular plate can be swung them mutually.
