Detailed description of the invention
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to detailed description of the invention, structure, feature and effect thereof of the picture frame wall hook proposing according to the present invention, be described in detail as follows.
As shown in FIG. 1A and 1B, be stereogram and the cutaway view of the first preferred entity of picture frame wall hook of the present invention.Picture frame wall hook 1 has substrate 2, and a hook body 3 is integrally connected to substrate 2.The U-shaped of U hook 4 is by forming below: the top 5 of substrate 2, the roof panel 6 of hook body 3, and the swash plate 7 that upward and outward extends of hook body 3.Obviously, the open top end 8 of U hook 4, for introducing picture frame hang spring (not shown), the transverse width having is greater than the transverse width of the bottom lock end 9 of U hook 4.
Inclined via-hole 10 laterally runs through hook body 3 and substrate 2, for receiving holdfast 11 and guiding holdfast 11 to enter wall 12 with oblique angle.Consequently, picture frame wall hook 1 can be around inclination holdfast 11 hinges or rotation.Obviously, through hole 10 has enough length to support holdfast 11.So, user can pre-assembled holdfast 11 in hook body 3 to picture frame wall hook 1 is installed on wall 12.Keep the method for holdfast 11 in through hole 10 to realize by frictional force, or cover the outlet 14 of holdfast with thin lid (not shown).In the time that hammer impacts holdfast 11, holdfast 11 can enter wall 12 through this thin lid.Consequently, in the time that picture frame wall hook 1 is installed at wall 12, user only needs hand-held substrate 2, and without hand-held substrate 2 and holdfast 11.The installation that this is conducive to facilitate picture frame wall hook 1, the holdfast 11 that allows user can impact like a cork inclination enters wall 12.Existing conventional art can not provide such function.
It should be noted that U hook 4 is arranged on the top of picture frame wall hook 1, holdfast 11 be arranged on the bottom of picture frame wall hook 1 and U hook 4 under.Therefore, when hanging picture frame on picture frame wall hook 1 time, user can first hand-held picture frame a little more than picture frame wall hook 1, then by wall down sliding picture frame, until picture frame hang spring enters U hook 4.Therefore the shortcoming of traditional top-anchor portion and the picture frame wall hook of bottom-hook portion is eliminated.
As shown in FIG. 1A and 1B, bottom-anchor portion of hook body 3 becomes the laterally extending even width of box-like shape, and its width is much smaller than the width of the open top end 8 of U hook 4.Consequently, the long holdfast comparison of relatively short holdfast 11(and United States Patent (USP) 7222833) can be used for fixing picture frame wall hook 1 on wall 12.In addition,, because U hook 4 can reduce size, in the time that picture frame hangs on wall, the picture frame back side and wall surface can keep gapless or minimum clearance.
Even if it should be noted that picture frame wall hook 1 has a relatively little volume, suitable finger touch-down zone is provided for the top 5 of substrate 2 or bottom 13 so that user installation picture frame wall hook 1.The bottom 13 of substrate 2 extends across the exit point 14 of holdfast 11 toward below.Consequently, picture frame wall hook 1, can not be carried in picture frame wall hook 1 top because of weight, and causes down hinge or come off from wall of picture frame wall hook 1.Hook body 3 also provides a solid holdfast hammering district, causes the damage of U hook 4 while preventing holdfast hammering.
As shown in FIG. 1A and 1B, picture frame wall hook 1 can be by injection molding, and still, picture frame wall hook 1 also can be formed by continuous bend by metallic plate, or any other method forms.The picture frame wall hook 1 forming by metallic plate continuous bend, in illustrated structure may from Figure 1A and Figure 1B can be slightly different.But such variation should be contemplated within the scope of the present invention.
As shown in Figure 2, be the stereogram of the second preferred entity of picture frame wall hook of the present invention.Picture frame wall hook 15 comprises: base plate 16, the first hook bodies 17 are integrally connected to the left side edge of base plate 16, and the second hook body 18 is integrally connected to the right side edge of base plate 16.Hook body 17 and 18 is identical with the hook body 3 in Figure 1A and Figure 1B.For simplifying object, author of the present invention does not intend in Fig. 2, to repeat to identify the assembling numbering of all parts.Obviously, picture frame wall hook 15 is double hook picture frame wall hooks, comprises a U hook 19 and the 2nd U hook 20, and they are identical with the U hook 4 in Figure 1A and Figure 1B.U hook 19 and 20 respectively has an open top end for receiving the hang spring (not shown) of picture frame, and the hang spring of a bottom lock end support picture frame.Obviously, the open top end transverse width of U hook 19 and 20, is greater than bottom lock end transverse width.U hook 19 and 20 by horizontal location on base plate 16.So, when picture frame wall hook 15 by horizontal location on wall, picture frame can keep balance and level.Hook body 17 and 18 provides respectively inclined via-hole 21 and 22 for receiving and guiding holdfast (not shown) to enter within the walls with oblique angle.Consequently, picture frame wall hook 15 can not rotate or hinge around holdfast.
Each through hole 21 and 22 has enough length and supports holdfast.Therefore,, in the time that picture frame wall hook 15 is installed, user can pre-install holdfast in picture frame wall hook 15.Holdfast remains in through hole 21 and 22 and does not come off and can be realized by frictional force, or covers the outlet of holdfast with thin lid (not shown).In the time that hammer impacts holdfast, holdfast can enter wall through this thin lid.
Importantly, even if U hook 19 and 20 has a relatively little volume, base plate 16 provides enough finger touch-down zones.In the time that picture frame wall hook 15 is installed, user can pin base plate 16 on the other hand by wall, and another hand-held hammering is beaten holdfast and entered wall.Hook body 17 and 18 also provides a solid holdfast hammering district, causes the damage of U hook 19 and 20 while preventing holdfast hammering.
As shown in Figure 3, be the stereogram of the 3rd preferred entity of picture frame wall hook of the present invention.Picture frame wall hook 23 comprises: substrate 24, the first hook body 25 is integrally connected to the left side edge of substrate 24, the second hook body 26 is integrally connected to the right side edge of substrate 24, and the first and second laterally extending bodies 27 and 28 are integrally connected to the middle section of substrate 24.Hook body 25 and 26 is identical with the hook body 3 in Figure 1A and Figure 1B, but has an exception, and exception is that hook body 25 and 26 does not arrange through hole.Picture frame wall hook 23 is double hook picture frame wall hooks, is provided with a U hook 29 and the 2nd U hook 30, and they are identical with the U hook 4 in Figure 1A and Figure 1B.U hook 29 and 30 respectively has an open top end for receiving the hang spring (not shown) of picture frame, and a bottom lock end is for supporting the hang spring of picture frame.Obviously, the transverse width of open top end is greater than the transverse width of bottom lock end.U hook 29 and 30 by horizontal location on substrate 24.So, when picture frame wall hook 23 by horizontal location on wall, picture frame can keep balance and level.The first and second laterally extending bodies 27 and 28 respectively provide inclined via-hole 31 and 32 for receiving and guiding holdfast (not shown) to enter in wall with oblique angle.Consequently, picture frame wall hook 23 can not rotate or hinge around holdfast.Each through hole 31 and 32 has enough length and supports holdfast.Therefore,, before installation picture frame wall hook 23, user can pre-install holdfast in picture frame wall hook 23.Holdfast remains in through hole 31 and 32 and does not come off and can be realized by frictional force, or covers the outlet of holdfast with thin lid (not shown).In the time that hammer impacts holdfast, holdfast can enter wall through this thin lid.
Importantly, top or the free end of laterally extending body 27 and 28, its horizontal level is below the horizontal level of U hook 29 and 30 inside bottom blind ends, and their transverse width is also little than the transverse width of U hook 29 and 30 open top end.Consequently, when hanging picture frame during at picture frame wall hook 23, user can first hand-held picture frame a little more than picture frame wall hook 23, then by wall down sliding picture frame, until picture frame hang spring enters U hook 29 and 30.In addition,, because U hook 29 and 30 can shorten size, in the time that picture frame hangs on wall, the picture frame back side and wall surface can keep gapless or minimum clearance.
Importantly, substrate 24 enough spaces are provided in case user with a hand-held substrate 24, holdfast is beaten in the hand-held hammering of another.U hook 29, laterally extending body 27, laterally extending body 28, U hook 30, has enough distances and enough holdfast hammering spaces is provided between them.
As shown in Figure 4, be the stereogram of the 4th preferred entity of picture frame wall hook of the present invention.Picture frame wall hook 35 is in conjunction with picture frame wall hook 15(Fig. 2) and picture frame wall hook 23(Fig. 3).In Fig. 4, picture frame wall hook 35 comprises substrate 36, the first and second hook bodies 37 and 38, and laterally extending body 39.Except the difference of shape, hook body 37 and 38 is identical with hook body in Fig. 2 17 and 18.The function of the laterally extending body 27 or 28 in the function of laterally extending body 39 and Fig. 3 is identical.Hook body 37 and 38 provides inclined via-hole 40 and 41 for receiving holdfast (not shown) and guiding holdfast wall to tilt into wall.Laterally extending body 39 provides inclined via-hole 42 for receiving holdfast (not shown) and guiding holdfast wall to tilt into wall.Obvious, owing to increasing a holdfast, the load capacity of the picture frame wall hook 35 of Fig. 4 is greater than the load capacity of the picture frame wall hook 15 of Fig. 2.
Finally, also have some important problems to need to answer.Can the load capacity of picture frame wall hook of the present invention be equal to the load capacity of traditional picture frame wall hook? can the load capacity of picture frame wall hook of the present invention be much larger than the load capacity of independent use holdfast load picture frame? how to improve to improve the load capacity of picture frame wall hook of the present invention? according to basic cantilever theory, following discussion provides the answer of all the problems referred to above.
Fig. 5 demonstrates the holdfast that is inclined upwardly and is subject to heavily loaded F.Heavy duty F can be broken down into revolving force Fy(=FcosD) perpendicular to holdfast, and tensile force f t(=FsinD) be parallel to holdfast.Obviously, tensile force f t is the direction that enters wall pushing away holdfast, instead of is extracting the direction of holdfast.
Fig. 6 demonstrates horizontal holdfast and is subject to heavily loaded F.Obviously, whole heavily loaded F is as revolving force Fy(=F).
Fig. 7 demonstrates downward-sloping holdfast and is subject to heavily loaded F.Heavy duty F can be broken down into revolving force Fy(=FcosD) perpendicular to holdfast, and tensile force f t(=FsinD) be parallel to holdfast.Obviously, tensile force f t is extracting the direction of holdfast.Revolving force Fy causes turning moment M(=Fy × R=F x cosD x R) around wall central rotation holdfast.There is moment of resistance Mr(=Fc x Rc simultaneously) produced by the compression stress Fc of holdfast.Wall is the embedding holdfast at whole section to the compression force distribution of holdfast.In order to use single Fc to represent that total compression power is distributed in the embedding holdfast of whole section, Fc must be positioned at compression force distribution center of gravity (=2/3R).
Keep holdfast in inactive state:
Compression stress Fc produces frictional force Fr:
Keep holdfast in inactive state:
The remarkable meaning of aforesaid equation is as follows:
(1) holdfast is extracted angle D and is determined by coefficient of friction u completely.Before holdfast rotates to and extracts angle, holdfast can not be pulled out.
(2) only have when the heavy duty of holdfast is enough to rotate holdfast and be equal to or greater than while extracting angle (=arctan0.75u), holdfast is just likely pulled out extracting angle.
(3), if the maximum load capacity of holdfast is defined as holdfast load weight and can not cause holdfast to be pulled out, holdfast load weight is enough to rotate holdfast and is equal to or greater than the maximum load capacity of extracting angle (=arctan0.75u) and should be regarded as holdfast.
(4) will keep holdfast to remain static (not being pulled out) at angle of inclination D, coefficient of friction u must be equal to or greater than (4/3) tanD.
(5), industrial, holdfast shearing strength is defined as causing holdfast to rotate load weight (or application of force of parallel wall surface) to a certain degree.Larger load weight causes holdfast to rotate largely.The load weight that therefore, can rotate holdfast is decided by holdfast shearing strength.
Fig. 8 to Figure 11 shows the various application of cantilever.The utility theory of cantilever is based on following supposition: (1) holdfast is can be not bending or the hardware of distortion.(2) cantilever is can be not bending or the hardware of distortion.(3) between holdfast and cantilever, angle is a not varied angle.Fig. 8 to Figure 11 shows that heavily loaded F causes turning moment M(=F X A) cantilever is rotated around the bottom edge of cantilever.Turning moment M causes tensile force f t to act on holdfast.Holdfast tensile force f t causes the rotation (Mr=Ft x B) of moment of resistance Mr resistance cantilever.Keep cantilever to remain static:
As shown in Fig. 8 and Fig. 9, A is much larger than B, and therefore holdfast tensile force f t is the multiple of heavily loaded F.Such cantilever is generally used for the bar tool that weighs anchor and follow closely.
As shown in Figures 10 and 11, A is much smaller than B, and therefore holdfast tensile force f t is the sub-fraction of heavily loaded F.Such cantilever is generally used for picture frame wall hook.Especially, Figure 10 represents the picture frame wall hook of traditional top-grasp and bottom-hook portion, and Figure 11 represents the picture frame wall hook of top-hook portion of the present invention and bottom-grasp.
The cantilever that shows Figure 11 as Figure 12 is in inclination angle D inactive state.Figure 13 shows that the amended cantilever of Figure 11 is in inclination angle D inactive state.The amended cantilever of Figure 11 is that the C of Figure 11 cantilever is eliminated to (being C=0).
In Figure 12: Ft=F x (H/B), wherein: H=[(B+C) x sinD]+(A x cosD)
In Figure 13: Ft=F x (H/B')=F x H/ (B+C), wherein: B'=B+C
Obviously,, when the identical load-carrying of cantilevered load, the holdfast tensile force f t of Figure 13 is the sub-fraction B/ (B+C) of the holdfast tensile force f t of Figure 12.This load capacity that represents Figure 13 cantilever is multiple (the B+C)/B of the load capacity of Figure 12 cantilever.Significantly, Figure 13 and Figure 10 provide identical load capacity and moment.Therefore,, if can cancel (Figure 11) C distance (being C=0) in picture frame wall hook of the present invention, we can improve the load capacity of picture frame wall hook of the present invention, thereby make it be equal to the struck capacity of traditional picture frame wall hook.
The front view of the 5th preferred entity of picture frame wall hook of the present invention as shown in Figure 14 A.How Figure 14 A and Figure 14 B cancel C distance (being C=0) at entity of the present invention for explanation, and therefore they not necessarily present detailed structure.In Figure 14 A, picture frame wall hook 43 is provided with inclined via-hole 44 and guides holdfast 45 to tilt to enter wall.Inclined via-hole 44 positions are on the top of picture frame wall hook 43, and its exit point 46(is the entrance that holdfast enters wall) be positioned at the inner side 47 near the bottom lock end of U-shaped hook 48.Therefore the entrance 46 that, holdfast enters wall is positioned at the inner side 47 near the bottom lock end of U-shaped hook 48.Consequently, picture frame mass loading in enter near holdfast wall entrance 46, distance C (referring to Figure 11) is therefore cancelled.
The front view of the 6th preferred entity of picture frame wall hook of the present invention as shown in Figure 14B.Picture frame wall hook 49 is provided with base plate 50, and the laterally extending body 51 tilting is integrally connected to the top of substrate 50.Laterally extending body 51 is provided with inclined via-hole 52 and guides the wall that enters that holdfast 53 tilts.The exit point 54(of inclined via-hole 52 is the entrance that holdfast enters wall) be located close to the inner side 55 of the bottom lock end of U-shaped hook 56.Consequently, picture frame mass loading is in the entrance 54 that enters wall near holdfast, and distance C (referring to Figure 11) is therefore cancelled.
Figure 15 A and Figure 15 B demonstrate L cantilever, the picture frame wall hook of representative graph 14A and Figure 14 B, and L cantilever and holdfast remain static in independent free body figure.In the free body figure of L cantilever, heavily loaded F causes turning moment M(=F X A) make L cantilever around its bottom edge rotation.Turning moment M causes holdfast tensile force f t.Holdfast tensile force f t causes the rotation (Mr=Ft xB) of moment of resistance Mr resistance cantilever.
Keep cantilever to remain static:
In holdfast free body figure, there is turning moment M(=Ft x B) be equal to the moment of resistance Mr in L cantilever free body figure.Holdfast heavy duty F(is conveyed to holdfast by cantilever) direction by the pivot of L cantilever bottom margin.Therefore, heavily loaded F does not form the revolving force of holdfast.Turning moment M causes compression stress Fc and the moment of resistance Mr(=Fc x Rc of wall to holdfast).Wall is the embedding holdfast at whole section to the compression force distribution of holdfast.In order to use single Fc to represent that total compression power is distributed in the embedding holdfast of whole section, the necessary position of Fc is at compression force distribution center of gravity (=2/3T).Keep holdfast in inactive state:
Compression stress Fc produces the frictional force Fr of holdfast.
Keep cantilever to remain static:
Aforesaid equation has following significance:
(1) in order to keep holdfast and cantilever in initial inactive state, minimized friction coefficient must be equal to or greater than (2/3) T/B.
(2) large heavy duty amounts may cause holdfast and cantilever from initial static state rotation.Holdfast and cantilever must be served as a monolithic entity rotation.The unique channel of its rotation is in rotary course, simultaneously outside mobile holdfast and the downward bottom margin that moves cantilever along wall.In fact, in the time of rotation, holdfast is in fact around fixing holdfast strong point rotation, and in fact cantilever rotates around the pivot of the cantilever bottom margin moving down.
Obviously,, if a heavily loaded amount can be rotated holdfast and cantilever simultaneously, its heavy duty amount must be rotated simultaneously and outwards be shifted and move holdfast.Comparatively speaking, this heavy duty amount is equal to and in Fig. 7, causes holdfast to rotate to holdfast extracting angle D(=arctan0.75u) heavy duty amount.
(3), if actual coefficient of friction is less than (2/3) T/B, a large heavy duty amount may start to extract holdfast before rotation at holdfast and cantilever.Obviously, borrow and increase B value, we can ensure that actual coefficient of friction will be greater than (2/3) T/B.Therefore, holdfast can not start to be pulled out before rotation at holdfast and cantilever.
Figure 16 A and Figure 16 B demonstrate the L cantilever of Figure 15 A and Figure 15 B from initial inactive state rotation D degree, and its cantilever and holdfast remain static in independent free body figure.Should be noted, the pivot O of the bottom margin of cantilever shown in Figure 16 A and Figure 16 B moves down a distance (=(B/cosD)-BcosD) from initial inactive state (Figure 15 A).
In the free body figure of L cantilever: heavily loaded F is broken down into two power F1 and F2.
F1 causes holdfast pulling force (=F1x A/B=FcosD x A/B), and F2 causes holdfast pulling force (=FsinD).
In the free body figure of holdfast: exist a turning moment M to be equal to the moment of resistance Mr in cantilever free body figure.
In addition, also there is a moment of resistance Mr(=Fc x Rc) produced by holdfast compression stress Fc.As previously discussed:
Compression stress Fc produces the frictional force Fr of holdfast.
Keep cantilever to remain static:
Aforesaid equation has following significance:
(1) holdfast pull-out angle D is independent of holdfast weight loading.But in order to pull out angle D pull-out holdfast at holdfast, load-carrying F must enough rotate holdfast and cantilever to holdfast pull-out angle D.
(2) the holdfast pull-out angle D that larger B value representation is larger.Represent that compared with large holdfast pull-out angle D holdfast rotation is not pulled out compared with large angle.The larger holdfast anglec of rotation represents larger loading capacity.Therefore, borrow and increase B value, we not only increase holdfast pull-out angle D, but also have increased loading capacity.
(3), if the dead weight of holdfast is defined as holdfast load weight and can not cause holdfast to be pulled out, holdfast load weight enough rotates holdfast and is equal to or greater than the dead weight of extracting angle D (=arctan0.75u) and should be regarded as holdfast.
(4), in order to obtain maximum loading capacity, the length of holdfast must be greater than T/cosD or 1.5u x B.
(5) in order to prevent that holdfast is drawn out before arrival pull-out angle D, coefficient of friction u must be equal to or greater than (2/3) x (T/B)/cosD.
Industrial, holdfast shearing strength is defined as causing holdfast to rotate load weight (or application of force of parallel wall surface) to a certain degree.Larger load weight represents that holdfast produces larger power stage, provides in order to produce larger empty area in wall the rotation degree that holdfast is larger.Therefore, can rotate holdfast to a certain extent the load weight of (as extracting angle D) be decided by holdfast shearing strength.Obviously, all aforesaid equations are cannot be in order to determine causing holdfast to rotate to load weight to a certain degree.
Even if we can not determine to cause holdfast to rotate to load weight to a certain degree, the ratio of the load weight of holdfast (Fig. 7) and cantilever (Figure 16 A) can be determined by method for simplifying below.
In Fig. 7, holdfast is around the central rotation of wall, and produces empty area holdfast rotation is provided.
In Figure 16 B, holdfast is a fixing holdfast strong point rotation in wall leading edge, and in wall, produces empty bulk area holdfast rotation is provided.
Through comparing:
Heavy duty F and holdfast swing D are linear direct ratios.In fact, the available angled straight lines representative of relation between heavily loaded F and holdfast swing D, the slope of its oblique line represents the shearing strength of holdfast.In holdfast rotary course, the power stage that holdfast produces can represent with the gross area under oblique line (=1/2x F x D).This is because power stage equals heavily loaded F and is multiplied by its displacement.
Wherein: F'/F=D'/D, (F'x D')/(F x D)=(F'/F)
2=2
The heavy duty amount of F' representative graph 16A causes holdfast rotation D' angle.The heavy duty amount of F representative graph 7 causes holdfast rotation D angle.
Aforementioned proportion is the power stage rotating based on holdfast completely, provides holdfast rotation in order to produce empty area in wall.In Figure 16 A, because holdfast and cantilever rotate as monolithic entity, holdfast need to produce extra power stage in order to overcome the frictional force of holdfast, forces holdfast outwards to move.In Fig. 7, holdfast can rotate simply, does not need to force holdfast outwards to move in rotary course.Obviously, in consideration Figure 16 A, holdfast need to produce under extra power stage condition, and the ratio of actual loading weight (Figure 16 A) and load weight (Fig. 7) should be much larger than 1.414.
