The specific embodiment

With reference now to accompanying drawing,, wherein identical Reference numeral is indicated identical element.In more detail with reference to the present invention, in Fig. 1 and Fig. 2, the hinge 100A in Fig. 2 is by cylinder 19(pivoting point now) form, two parts on cylinder side are called the

wing

16 and 17, and wherein a side is called the framework wing 17, and opposite side is called a wing 16.It is upper that the framework wing 17 is arranged on door frame 200A, and a door wing 16 is installed on door 200, and cylinder 19 keeps together two

wings

16 and 17, serves as pivot in the execution of its function simultaneously.

The hinge 100A that safety device 100 in Fig. 1 is formed for using Fig. 2 is used the

wing

16 and 17 fixed gates 200 particularly.The block that safety device 100 is made by the combination of firm plastics, metal, metal alloy or any other suitable material or material, semicylinder, semiellipse block or any other suitable useful form form, it has hollow perforate cylinder, have opened gap along this cylindrical whole length, this opened gap is enough wide to hold two

wings

16 and 17 together close to each other.This cylinder is configured as the hollow area 6 of picture " C " shape, roughly is positioned 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.Forwardly on the top of face 1, or on any other correct position of safety device, there is the bar 5 of optional semicircle, half elliptic or any other shape, the stiffening device of the distally reveal section 3 that this bar is body as two relative distal portions or the part of body and the distally door frame sidepiece 4 of body.Bar 5 also serves as handle or shakes hands with handling safety device 100.Can also comprise the optional design of mirror image of handle or handle.Safety device 100 has the opening that is positioned at 2 places, the back side of band " C " shape hollow area 6 or HC6, with two close ends 9 by the wing and 10 and cylinder 19 self clamping and being fixed together, and the overlay area with end face place of the top board 30 be called as shown in Figure 3 in top board 21 and Fig. 4, not shown this top board in Fig. 1, because it is cut off to show the upper part of safety device 100 for illustration purpose.Top board serves as stiffening device and the retainer of this device.

Safety device 100 is the part near cylinder by two close ends 9 by the

wing

16 and 17 and 10() cylinder 19 of part and hinge 100A closely is clamped together and works.Therefore, the amount of the motion of this clamping action restriction when opening 200D, and the degree opened of swing 201D between moving period of the distal portion 11 that also will be limited in framework wing distal portion 12 of the door wing while remaining static.As a result,

alar part

11 and 12 each other the closer to, the door gap open less.This is due to chucking power, and this chucking power can be fixed together two

wings

16 and 17, particularly

close end

9 and 10 closely is fixed together each other, clamps cylinder 19 simultaneously.Once safety device 100 is securely held hinge 100A, it will be as key support to be held in place safety device 100 together with whole body.Particularly, the part 3 and 4 of safety device 100 is to make tolerance to be applied to the main key element of the power of the pressure on safety device 100 when door 200 is inwardly opened 200D.It is wider that this device will not allow door 200 to open 200D, but open with the limited amount of installing 100 permissions.

Once safety device 100 manufactures, to make it slide into hinge 100A upper, and two relative distal part 3 of the body of

safety device

100 and 4 are just served as support and inwardly opened the door 200 power 200E that apply of 200D and the pressure of 200F with tolerance against the contact between the back side 2, door 200 and the door frame 200A of safety device 100.It will only allow door 200 inwardly to open the amount that 200D reaches safety device 100 permissions.Pressure 200E is door 200 power that apply of 200D of opening against the back side 2 of the body 3 of safety device 100, and pressure 200F is the power that the back side 2 against the body 4 of the safety device 100 of door frame 200A applies.By using cylinder 19 as fulcrum and as center fixing and that support, safety device 100 also serve as 200 and door frame 200A between the lever reaction force.It is also by the

restriction wing

16 and 17, particularly the

part

9,10,11 of the wing and 12 and door 200 motion and working.

Body 3 by extending or

shorten safety device

100 and 4 one or two length and/or size, can manufacture other replacement device (not shown).In other words, body 3 and 4 is longer and firmer, is used for stoping door 200 to open 200D more firm and firm over the support of the amount of user's permission of safety device 100.

Due to the inconvenience of carrying huge device, and the hotel door open the inconsistent setting that swings side, (as described) similar small size body 3 and 4 of standard is arranged as the practical dimensions manufacture of the safety device 100 for travelling of mancarried device.Yet; depend on apart from 202C; domestic safety device 100 can manufacture that several are multi-form, this distance be hithermost adjacent vertical wall 202B(in hinge side door frame 202A and Fig. 1 or as outstanding doorframe shut die or fastening devices in the 202D of the vertical wall in Figure 1A) between distance.It is far away that adjacent vertical wall 202B leaves hinge side door frame 202A, and the distally door frame sidepiece 4 of body can be made longer (larger), and this will cause the firmer supporting base for safety device 100.In other words, the length (size) of the distally door frame sidepiece 4 of body is determined by distance 202C.And, in the distally of body reveal section 3, always can reasonably make long enough so that more firm and firmer support to be provided, this is the distally reveal section 3 due to the longer size for body, does not have the restriction apart from 202C.

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

(the face with " C " shape hollow area 6 in the back side 2 of safety device 100 separates amount that 200B is greater than hope with the space between door 200 and door frame 200A, allow door 200 to open 200D and be greater than the amount of wishing gap) situation in, in Fig. 3, there is optional compensation device 100B, its top board 21 parts are enough usingd greatly as handle 22 and as stiffening device, roughly in the central area of compensation device 100B, have the space 26 of cutting away fully.Space 26 is clamped together for the

close end

9 and 10 of two wings, and so that it slides on two

close ends

9 and 10 of the

wing

16 and 17 200I.It has two body parts, right body part 23 and left body part 24, this body part there is enough sizes, width and the degree of depth in case suitably fill safety device 100 the back side 2, the door 200 and door frame 200A between redundant space 200B.

Optional compensation device 100B in Fig. 3 has dual-use function, at first as mentioned above restricted quarter 200B, secondly and by two

wings

16 and 17, two

close ends

9 and 10 closely are fixed together particularly, and provide extra clamping force in less degree,

distal portion

11 and 12 closely being fixed together.

Parts by the compensation device 100B by Fig. 3 are incorporated on main safety device 100, preferably, in the device 100H in Figure 19, realize for realizing the alternative mechanism of function same as described above.Be incorporated into this alternative mechanism in device 100H and be described to Fig. 4 to the device 100C in Figure 10.Device 100C has can be shaped as square body, rectangular body, cylindrical body or multiaspect body (this has the body of multiple not coplanar not to be illustrated) two independently removable centers.They are called as left removable central area 29 or " LMCA " 29, and right removable central area 28 or " RMCA " 28.In each of two posterior components (left dorsal part body 34 parts or " BLB " 34 and right dorsal part body 33 parts or " BRB " 33) of body, there is a removable central area.They pass through the back side 27 parts and external discrete, and separate with inside by " C " shape hollow area 31 in the irremovable back side 38 parts of device 100C.Except (not shown) in cylindrical situation (in this case, it will suitably be placed), these two independently removable central area LMCA29 and RMCA 28 are equipped with little sliding rail 28A and 29A or allow any other surface of easily sliding in each of its contact slide face.LMCA 29 and RMCA 28 have movably back portion 39, and both be placed and connect and make when using any expansion (stretching, extension) mechanism (such as the method for inwardly tightening 200L in Fig. 8), support 41(pedestal) expansion screw that is connected to one or more turn 202L or realizes in a similar manner, be retracted in appropriate location to maintain support 41.This expanding mechanism can make two turn 202L expansion, and vertically 201L leaves the irremovable anterior face 44 of safety device 100C or 37 parts and makes two removable central area LMCA29 of independence and RMCA28 move forward 200K.

Below describe and will describe this mechanism and how work.In the irremovable anterior face portion 44 of safety device 100C in Fig. 8, have large screwed hole (having outer aperture 42 and inner openings 43), the equal large threaded screw that is called adjustment screw 36 is outstanding through this hole.At the inner end of adjustment screw, it and the pedestal 41(support of the appropriate size of the expansion screw that is connected to one or more turn 202L or realizes in a similar manner) contact-enhancing 203L zone contact.Turn 202L is connected in any suitable position in support 41.Simultaneously, turn 202L is connected on the mirror image position of the correspondence on irremovable anterior face portion 44.Turn 202L is retracted within appropriate location for maintaining support 41, and support 41 is also connected to BLB34 and BRB33 part two independently removable center 28 and 29 zones or LMCA29 and RMCA28.In outside the other end of adjustment screw, usually there is little Metallic rod 200J, or any other differing formed handle, such as the 100D in Fig. 9 or the 100E in Figure 10.Little Metallic rod 200J is perpendicular to adjustment screw 36 self, when tightening adjustment screw 36 with expansion pedestal 41(support) when (this expands two turn 202L simultaneously), it is for obtaining leverage.Tightening of adjustment screw 36 can mobile BLB34 and two of the BRB33 part independently removable center 28 and 29 zones or LMCA29 and the more close door 200 of RMCA28 and door frame 200A, and 200B is separated in the undesirable space therefore reduced between back movable surface 39, door 200 and the door frame 200A of safety device 100C.

In the situation of the other similar designs 100F in Figure 14, wherein use two threaded holes at Figure 11, so they will with two adjustment screw (the right adjustment screw 47 in Figure 12 and left adjustment screw 48) complementation.Two adjustment screw 47 with 48 each will with the pedestal 45 separated and 46(support) contact, and each of

pedestal

45 and 46 will be connected to turn

202L discretely.Pedestal

45 and 46 each also will be connected to discretely two independently removable

central area

49 and 50 each, removable central area is connected to LMCA50 and another removable central area is connected to RMCA49.Both be designed to slide on little track 49A and 50A, and quite in Fig. 8 of function and other element of the device 100C in Figure 12 and 100F and their working mechanism with above-described identical.

Cause the alternative design of identical result and mechanism to separate reducing of 200B for realizing the space between different safety devices 100, door 200 and door frame 200A, can be in the situation that do not depart from the principle of safety device 100 and be used.

In the market of today, for the accommodation entrance with for two kinds (2) commercial popular hinge model of the main entrance of house, be: adjustable springs door hinge (ASDH) and ball bearing door hinge (BBDH).Also can consider other hinge model.

ASDH in Fig. 2 has the safety pin that is measured as about 1.5 centimetres (1.5cm).Once pin 100A is fixed on appropriate location and regulates its tension force, this is sold just for keep-spring tension force.The slot 15 of pin is positioned on the side of upper end 13 of cylinder 19 (position of the wing is depended at the Huo center).Once pin is placed in the slot 15 of pin, half of its just outstanding cylinder 19 about its length.

Therefore, the Figure 15 that has the right side body 54 that separated by " C " shape hollow area 51 and a left side body 55 manufactures the ledge of the pin of being convenient to hold about 0.75 centimetre (0.75cm) to the safety device 100G in Figure 18.Therefore, bottom 56 retained parts of the bottom 60 that there is no top of " C " shape hollow area 51 and safety device 100G manufacture and are different from the relative upper end 57 that top 59 is arranged.There is the ledge of cut-away area 52 with the pin that allows to hold hinge 100A in 53 bottom, the back side of safety device 100G 56, and do not hinder safety device 100G from bottom upward sliding 200H to appropriate location.

For ASDH, because the ledge of pin, the slip 200H in Figure 15 of safety device 100G will upwards reach outstanding pin in the situation that top board 59 is put upside down from bottom.Breech lock 200G can stretch out or retract, this breech lock is crossed over and is opened the top board 59A that space 60A is fixed to imitate " C " shape hollow area 51 retained parts, in order to hinder the down sliding of safety device 100G from hinge 100A, this due to safety device 100G, has a top board 59 and this top board is put upside down in this case.Also can use any other device or the feature that work as breech lock 200G, and not depart from the principle of safety device 100G.

Figure 19 is to have right base side 62 that " C " shape hollow area 66 in the back side 61 or HC66 divide out and the device 100H of left base side 63 to another the alternative practical design 100H in Figure 21.In HC66, to be not less than the sufficient degree of depth and the width of 0.75 centimetre (0.75cm), the whole length of edge " C " shape hollow area 66 or HC66 on one or both sides, except top board 64 zones, by the

extra opening

67 or 32 cut out in Fig. 4-13, to allow safety device 100H, do not collide the ledge of the pin of cylinder 19 from top slide 65 to bottom.This selection will not require otch 52 zones in the bottom 56 of safety device 100G needs Figure 15.

For Figure 19, to the alternative practical design 100H in Figure 21, safety device 100H is downward 65 from top to the slip in its appropriate location, rests on the top board 64 of cover part of clamping " C " the shape hollow area of erecting device 100H or part 66.In the situation that do not depart from the principle of safety device 100, also consider current unshowned any other improvement or the modification of the ledge for holding pin.

BBDH does not have any outstanding pin; Therefore any clamping " C " shape

hollow area

6,31,51 66 or any device 100C, 100F, 100G or 100H can be for making this device from the top down sliding to appropriate location, rest on the top board of cover part of any one any clamping " C " shape hollow area of safety device given here.

Any other modification that any commercially available hinge 100A is made will meet the modification of safety device 100 and not depart from its original principle.

Safety device 100,100C, 100F, 100G or 100H also can be for the less hinge 101A of Figure 22, and needn't manufacture the safety device of multiple different size.Add hinge cylinder booster 100J in Figure 23 and Figure 24 or HBA 100J on the length of cylinder 69 that can be in Figure 22 and increase the thickness of cylinder 69 by interpolation hinge cylinder booster 100J with the movably empty space 7(reduced in the Fig. 1 " C " shape

hollow area

6,31,51 or 66 in).Hinge cylinder booster 100J has to inward flange 71(border, edge in an end of two hollow 73 end), perhaps alternatively there is top board 72, in this case, only there are 68 ends, a hollow bottom, and top board 72 retainer or retainer as hinge cylinder booster 100J the same as edge 71 stop it to slide this cylinder of 200M when being placed on appropriate location.
