With reference now to accompanying drawing, wherein identical reference instruction identical element,.Now referring more particularly to the present invention, In fig. 1 and 2, the hinge 100A in Fig. 2 is made up of cylinder 19 (pivoting point), and two parts on cylinder side are referred to as the wing 16 He 17, wherein side is referred to as the framework wing 17, and opposite side is referred to as the door wing 16.The framework wing 17 is arranged on door frame 200A, and door The wing 16 is installed on door 200, and two wings 16 and 17 are kept together by cylinder 19, serve as in the execution of its function simultaneously Pivot.

Safety device 100 in Fig. 1 is formed for specifically solid using the wing 16 and 17 using the hinge 100A in Fig. 2 Determine door 200.Safety device 100 is by the combination system of firm plastics, metal, metal alloy or any other suitable material or material Block, semicylinder, semiellipse block or any other suitable useful form composition becoming, it has hollow perforate cylinder Body, has opened gap along this cylindrical whole length, this opened gap sufficiently wide with accommodate close to each other together two The individual wing 16 and 17.This cylinder is shaped like the hollow area 6 of " C " shape, is located substantially at the central authorities at the back side 2 of safety device 100, To allow clamping cylinder 19 and clamping door wing close end 10 and framework wing close end 9.On the top of forward face 1, or in safety On any other correct position of device, there is the bar 5 of optional semicircle, half elliptic or any other shape, this bar is used Make two relative extremitys of body or part be the distally door sidepiece 3 of body and the distally door frame sidepiece 4 of body plus Intensity device.Bar 5 also functions as handle or handle with handling safety device 100.The mirror image that handle or handle can also be included optional sets Meter.Safety device 100 has the opening at the back side 2 of band " C " shape hollow area 6 or HC6, by two close ends of the wing 9 and 10 and cylinder 19 itself clamping and being fixed together, and have as shown in Figure 3 referred to as in top board 21 and Fig. 4 Overlay area at the top surface of top board 30, this top board not shown in FIG, because it is cut off to show for illustrative purposes The upper part of safety device 100.Top board serves as stiffening device and the retainer of this device.

Safety device 100 passes through two close ends 9 and 10 (near the part of cylinder) part of the wing 16 and 17 and hinge The cylinder 19 of 100A is closely clamped together and works.Therefore, this clamping action limits the motion when door opens 200D Amount, and when also the distal portion 11 being limited in the framework wing being remained static the distal portion 12 of the door wing swing 201D motion during The degree opened.As a result, alar part 11 and 12 is each other the closer to opening of door gap is less.This is due to chucking power, this clamping Two wings 16 and 17 can be fixed together by power, specifically close end 9 and 10 is fixed together closer to each other, simultaneously Clamping cylinder 19.Once safety device 100 is rigidly clamped to hinge 100A, it will act as key support with whole body Together safety device 100 is held in place.Specifically, the part 3 and 4 of safety device 100 is formed into tolerating and inwardly beats when door 200 Open the Chief element of the power of the pressure being applied to during 200D on safety device 100.This device would not allow for door 200 and opens 200D is wider, but the limited amount being allowed with device 100 is opened.

Safety device 100 is manufactured so that it once slides on hinge 100A, two phases of the body of safety device 100 To distal part 3 and 4 act as support to tolerate between the back side 2 against safety device 100, door 200 and door frame 200A Contact inwardly open 200D door 200 apply power 200E and 200F pressure.It will only allow door 200 inwardly to open 200D Reach the amount of safety device 100 permission.The door of 200D is opened at the back side 2 that pressure 200E is against the body 3 of safety device 100 The power of 200 applyings, and pressure 200F is against the back side 2 applying of the body 4 of the safety device 100 of door frame 200A Power.By using cylinder 19, as fulcrum and as center that is fixing and supporting, safety device 100 also functions as door 200 and doorframe Lever counteracting force between frame 200A.It is also by the restriction wing 16 and 17, the specifically part 9,10,11 and 12 of the wing and door 200 motion and work.

By one or two length and/or the size of prolongation or the body 3 and 4 shortening safety device 100, permissible Manufacture other substituted device (not shown).That is, body 3 and 4 is longer and firmer, for stoping door 200 from opening 200D The support exceeding the amount of user's permission of safety device 100 is more firm and firm.

Due to carrying the inconvenience of bulky device, and the inconsistent setting opening swing side of hotel door, as portable The manufacture of practical dimensions of the safety device 100 for travelling of device has (as described) the similar small size body of standard 3 and 4.However, depending on apart from 202C, domestic safety device 100 can be made into several multi-forms, and this distance is hinge side Hithermost adj acent vertical wall 202B in door frame 202A and Fig. 1 (or as prominent in the 202D of vertical wall in Figure 1A Door frame mould or fixing device) the distance between.It is more remote that adjacent vertical wall 202B leaves hinge side door frame 202A, body Distally door frame sidepiece 4 can make longer (bigger), this will lead to the firmer support group for safety device 100 Seat.In other words, the length (size) of the distally door frame sidepiece 4 of body is determined by apart from 202C.And the distally door in body In sidepiece 3, always can reasonably make long enough to provide stronger and firmer support, this is due to for body For the distally door sidepiece 3 of longer dimension, there is not the restriction apart from 202C.

The body construction of safety device 100 described above can more suitably be used for residential environment, because user will know The geographical position with respect to nearest neighbor vertical wall 202B for the road hinge side door frame 202A.

In having between face and door 200 and the door frame 200A of " C " shape hollow area 6 in the back side 2 of safety device 100 Be spatially separating in the case of 200B is more than desired amount (i.e. it is allowed to door 200 opens 200D is more than the amount in gap of wishing), then exist There is optional compensation device 100B in Fig. 3, its top board 21 partly sufficiently large for use as handle 22 and as stiffening device, greatly Cause that there is in the central area of compensation device 100B the space 26 fully cut away.Space 26 is used for the close end 9 of two wings It is clamped together with 10, and so that its slip 200I on two close ends 9 and 10 of the wing 16 and 17.It has two bodies Part, right body part 23 and left body part 24, this body part has enough sizes, width and depth so that suitably Redundant space 200B between the back side 2 of filling safety device 100, door 200 and door frame 200A.
