Patent documentation 6: No. the 3091481st, Japanese Utility Model communique

In the fixed form on aforesaid floor 4; According to reference to (A) of Fig. 9, the fixed form that (B) explains; Peel off floor 4 even want to supporting member 5 tops; Because the inwall of the groove 41 that forms on the side 40 on floor 4 contacts with the flange part 101 or the bonding jumper 111 of floor fixture 100,110,, floor 4 can not be stripped from so being fixed on the supporting member 5.

But; Above-mentioned the fixing of floor fixture 100,110 that pass through; Owing to be on the floor 4 and floor fixture 100, directly connect between 110, so although floor 4 not can to above effective aspect peeling off, the power that move along long side direction on restriction floor 4 a little less than.

Therefore; When the people walks grade on as above fixing floor 4; If floor 4 is applied in the power that moves to long side direction; Then the floor might be moved and deviates to long side direction, for example need take this moment on the both end sides of the long side direction on floor 4, to be provided with the butt-end on floor 4 and limit the measures such as crossbeam that move on the floor.

But,, cause floor 4 expansions or contraction etc. owing to consider the variation of following temperature and humidity even can not cross crossbeam and move through end that crossbeam makes floor 4 as above is set; Between the end on floor 4 and the crossbeam some gaps need be set; So when the people walked, if move along long side direction with said gap portion on floor 4, the end collision that makes floor 4 was on aforesaid crossbeam at every turn; Then because said collision can produce noise, and produce distortion wait be out of shape, breakage.

According to patent documentation shown in Figure 10 1 described floor fixture 100; Through making on the flange part 101 the nip inwall of groove 41 on floor 4 of the claw 103 that is provided with, connect the floor 4 that adjoins each other (patent documentation 1 the 0055th section), through claw 103 is set; Floor fixture 100 is endowed and " dog " similar function; When this claw 103 being set and making it nip floor 4, floor 4 firmly is connected with floor fixture 100, its result; When using said floor fixture 100, can prevent effectively that also floor 4 from moving to long side direction.

But floor 4, the floor 4 that particularly formed by synthetic wood can to produce on bigger change in size, the especially long side direction on floor 4 change in size big because of the variation of temperature and absorption of water state etc.For example, the situation of the wooden hard board of 6m is following.

Linear expansion coeffcient: 4.4 * 10 ^-5(℃ ^-1); Measure temperature range :-10 ℃～90 ℃ (according to JIS K 7197)

According to (expansion length=linear expansion coeffcient * plate length * temperature difference)

The expansion length Dispute Resolution Mechanism of NAFTA Chapter Eleven ⊿ L that the 6m plate is long): ⊿ L=5.28mm (20 ℃ → 40 ℃: temperature difference "-f " flag ⊿ T)=20 ℃ the time); ⊿ L=10.56mm (20 ℃ → 60 ℃: ⊿ T=40 ℃ time).

Therefore, as the floor fixture 100 of Figure 10, make claw 103 nip floor 4 with firm connection floor 4 and floor fixture 100; Then can't absorb floor 4 because of expanding or shrinking the change in size that produces; Effect has bigger power on floor fixture 100, thereby floor fixture 100 breakages or distortion takes place, screw 7 ' comes off, and can not fixed floor 4; In addition, floor 4 possibly produce distortion such as deflection and distortion.

Therefore; Preferred floor fixture is fixed floor 4 as follows; Promptly; When person walks etc., apply and can limit floor 4 under the degree of the load under the common user mode and move, and when floor 4 because of expanding or when shrinking when self producing change in size etc., being applied in make floor fixture damaged degree powerful and causing power that floor 4 moves, can allowing floor 4 to move.

To said requirement; According to the floor fixture of putting down in writing with reference to the patent documentation 2 of Figure 11 explanation 110; Form floor fixture 110 by flexible materials such as resin materials, make 110 distortion of floor fixture, improve the pressing force of the inwall of the groove 41 that is provided with on the side 40 on 111 pairs of floors 4 of bonding jumper through being screwed into screw 7 '; Limiting floor 4 moves to long side direction; Make the people floor 4 moved, when floor 4 is applied with great power because of expand or contraction etc. changes size self, can allow floor 4 to follow said change in size and move in the power that walking on the floor 4 etc. usually applies under the user mode.

But,, produce distortion in order to make floor fixture 110 according to the floor fixture 110 of aforesaid patent documentation 2 records; Preferred embodiment; On intermediate 112, form breach, perhaps adopt on the bonding jumper 111 structure that forms heavy section and thinner wall section etc., its shape complicacy that becomes.

In addition; For the head that when constructing, makes screw 7 ' is hidden in the gap that forms between the floor 4; According to the floor fixture 100 that (A) and Figure 10 with reference to Fig. 9 explain, the diameter r of the head of screw 7 ' need be less than the groove width W that forms on the floor fixture 100 ₁, in addition, according to the floor fixture 110 with reference to Fig. 9 (B) and Figure 11 explanation, the diameter r that the screw of use need make head is (below, said interval is called " joint gap ") W at the interval between the side 40 on the floor 4 of adjacency ₂Below.

Therefore, if with the joint gap W on floor 4 ₂Narrow mode is constructed, and the diameter r of the head of the screw 7 ' that then must be to use also diminishes, thereby makes from the torque of instruments such as screwdriver that the instrument that forms on the head is chimeric to deform with depression, and its result can not be screwed into screw 7 '.

On the other hand, with reference in the floor 4 of Fig. 9 (B) and Figure 11 explanation fixing, the diameter r that specially uses head is greater than joint gap W ₂The situation of screw under; When being screwed into said screw 7 ', because the side 40 on the head of screw 7 ' cutting floor 4, make the degraded appearance after the construction; And, need labor energy in order to improve the part that outward appearance is pruned with the head of landfills such as putty repairing screw 7 '.

In addition,, be tilted when squeezing into etc., can produce the situation that the side 40 on floor 4 is cut so too at screw 7 ' even at the diameter that uses head during less than the screw of joint gap 7 '.

In addition; In the embodiment shown in Figure 1, shown in the front view of Fig. 1 (A), it is low that the upper end of distance piece 2 forms the two ends of central height and width; And the whole oval breach circular shape that forms the band circular arc of central bulging; But the shape of floor fixture 1 is not limited thereto, and it is all identical that the upper end of distance piece 2 can form the optional position height, or forms for example trapezoidal that middle body is high, the width two ends are low.And, can also with the part corresponding with the tapering, upper end of jack among (B) of Fig. 1 all or the part cut away, form the shape that the central portion shown in (A) of Fig. 2 caves in.

In addition, as one for example shown in Figure 4, can on the two ends of the width of distance piece 2, the variant part 24 from the abducent V word of the end edge of distance piece 2 shape be set.

Under the state before floor fixture 1 is installed; The Breadth Maximum of said variant part 24 can be greater than the wall thickness of distance piece 2; But after deforming when mounted, said variant part 24 has the deformability of the side 40 of not limiting floor 4 and the clamping exposure level of the side of distance piece 2.

The distance piece 2 that as above forms intersects with said bonding jumper 3 overlooking the width central authorities that are roughly rectangular bonding jumper 3, thus the crosswise shown in the cross-sectional side view of whole (B) that forms Fig. 1 of floor fixture 1.

As long as can insert the groove 41 that forms on the side 40 on floor 4; Said bonding jumper 3 can form the certain even shape shown in Figure 2 of integral thickness; Or form and shown in Figure 1 have the shape of rib at periphery; And, can also on the part that groove 41 internal faces bonding jumper 3 and floor 4 contact, the raised line identical with aforementioned distance piece be set.

From the lower end of distance piece 2 to the height l (with reference to (A), (B) of Fig. 1) of the lower end of bonding jumper 3, can with from the floor 4 the back side identical to the height L (with reference to (A) of Fig. 5) of the floor rear side inwall 41a of groove 41, but preferably a little less than said height L.

In addition; The maximum ga(u)ge of bonding jumper 3, be the thickness of the periphery of bonding jumper 3 in the embodiment of Fig. 1, can be identical with the width of the groove 41 that forms on the side 40 on floor 4, bonding jumper 3 is compressed in the embedded groove 41; Perhaps also can be less than the width of groove 41, in bonding jumper 3 movable embedded grooves 41.

In addition, when distance piece 2 was clamped between the side 40 on floor 4, the size of bonding jumper 3 formed, and bonding jumper 3 is not interfered with the inwall on the floor 4 in the deep that is present in groove 41.

The floor fixture 1 that as above forms utilizes fixture 7 that the floor is fixed on the supporting member 5, preferably utilizes the screw that has the dish type head as said fixture 7, is so-called countersink head screw, and the floor is fixed on the supporting member 5.

Forming of said floor fixture 1 as the screw 7 of fixture overall height lengthening with respect to distance piece 2, and remove head 71 and can insert the jack 21 that forms on the distance piece 2 with the thickness of exterior portions, so that can guarantee to squeeze into the degree of depth of supporting member 5.

(job practices and effect)

Shown in Fig. 5 (A), (B); According to the as above floor of the present invention fixture 1 of structure; Bonding jumper 3 is inserted in the groove 41 that forms respectively on the opposite flank 40 on floor 4 of configuration; And distance piece 2 is clamped between the side 40 on floor 4, the side 40 on floor 4 is contacted with the side 23 of distance piece 2.

When floor fixture 1 had variant part 24 shown in Figure 4, the interval of adjustment between the floor 4 was so that the distortion through said variant part 24 makes the side 40 on floor 4 and side 23 face contacts of distance piece 2.

Through said operation, the joint gap W that forms between the floor 4 ₂Wall thickness by distance piece 2 is orientated certain width as, can be with joint gap W ₂The state laying floor 4 of neat appearance.

Under said state, will be inserted into screw 7 in the jack 21 when squeezing into supporting member 5; The lower end of distance piece 2 is by being pressed on the supporting member 5; The back side of bonding jumper 3 thus, is fixed on floor 4 on the supporting member 5 by floor fixture 1 by on the floor rear side inwall 41a that is pressed in groove 41 simultaneously.

Like this, can be corresponding to the configuration space of supporting members such as joist 5, on the long side direction on floor 4 with predetermined distance, as the interval of an example about with 450mm, fixed floor 4 in many places.

Not floor fixture 1 directly to be fixed on the floor 4 through nail, screw, bonding agent etc.; But the face contact of the floor rear side inwall 41a of the back side through aforesaid bonding jumper 3 and groove 41; And the face contact of the side on floor 4 40 and the side of distance piece 2, make the floor become fixing state, compare with fixture (with reference to (B) of Fig. 9) as the T word shape of DESCRIPTION OF THE PRIOR ART; Utilize the structure of aforesaid floor fixture 1; Through above bonding jumper 3, also being provided with distance piece 2, having increased the side 40 on floor 4 and the contact area of floor fixture 1, thereby increased contact resistance.

And; In the embodiment of Fig. 5; The above-below direction that on the side 23 of distance piece 2, is formed with this distance piece is the raised line of length direction; Promptly with the raised line 22 of the flute length edge direction vertical direction of 4 sides, said floor, thereby also increased the contact resistance of side 40 on side 23 and the floor 4 of distance piece 2.

And, in floor fixture 1 fixing, have diameter greater than joint gap W through aforesaid ₂The countersink head screw 7 of head 71 on supporting member during fixed floor; Because being screwed into along with said countersink head screw 7;

Chamfered section

43,43 face contacts that form on the inclined side 71a that is provided with on the head 71 of countersink head screw and the bight, upper end on floor 4; So utilize inclined side 71a and the contact resistance on floor 4 of the head 71 of said countersink head screw, also limited moving of floor 4.

And; On the two ends of distance piece 2 widths, be provided with the variant part 24 of V word shape,, utilize power that said variant part 24 will elastic recovery to push the side 40 on floor 4 according to this structure; And when floor 4 will be when long side direction moves; Because the leading section of variant part will move with the floor, the outwards expansion of a certain side's variant part 24 is so further increased the contact resistance to the side 40 on floor 4.

Therefore, under floor 4 and floor fixture 1 state of contact, for load or the power that the people applies under the common user mode of walking on the floor 4, can produce is enough to make floor 4 not moved and fixing power.

On the other hand; For example floor 4 is followed the variation of temperature and humidity and is expanded or shrink; The size on floor 4 self changes; During extremely strong power that generation makes that the contact position of itself and floor fixture 1 moves, because floor 4 directly fixes with floor fixture 1 aforesaid nail of no use, screw, bonding agent etc., so can allow floor 4 to move.

Its result; Even the change in size of this expansion or contraction is followed on floor 4; Also can effectively prevent 1 breakage of floor fixture, prevent the screw 7 that floor fixture 1 is fixed on the supporting member 5 is thrown off, and can prevent that floor 4 from producing distortion such as deflection and distortion.

In addition; As shown in Figure 2; Tip shape top 22a is biased in any side of the width of raised line 22; In possessing the floor fixture 1 of this raised line 22; When the side on the raised line 22 of said floor fixture 1 contact floor 4 shown in Fig. 6 (A), (B), the power that move on the restriction floor 4 that said floor fixture 1 produces is following: compare the power grow that move to the arrow A direction shown in Fig. 6 (A) on restriction floor 4 to the situation that the arrow B direction shown in Fig. 6 (B) moves with restriction floor 4.

That is, in above-mentioned example, shown in Fig. 6 (A), floor 4 arrow A direction when moving in figure, the top 22a of the raised line 22 of the floor fixture 1 that forms by flexible material outside expansion deformation and shown in arrow a among the figure by mobile institute's tractive on floor 4.Its result, the distortion through said raised line 22 has increased the contact resistance with the side 40 on floor 4.

On the other hand, shown in Fig. 6 (B), floor 4 arrow B direction when moving in figure, the top 22a of the raised line 22 of the floor fixture 1 that is formed by flexible material is inwardly narrowed distortion by mobile institute's tractive on floor 4 shown in arrow b in scheming.Its result when the raised line 22 of above-mentioned shape is set, moves to the arrow B direction with respect to restriction floor 4, and floor fixture 1 has more firmly limited floor 4 and moved to the arrow A direction.

As stated, fixture 1 basis in floor shown in Figure 2 is towards difference, and the restraint that floor 4 is moved is different; For example shown in Fig. 6 (C); Every at a distance from predetermined distance on the long side direction on floor 4, alternately (1a～1d) is when the arrow A direction moves reverse configuration floor fixture 1 in Fig. 6 (A) on floor 4; Utilize floor fixture 1a, 1c to bring into play the effect that restriction is moved more firmly; Otherwise when the arrow B direction moves in Fig. 6 (B), utilize floor fixture 1b, 1d to bring into play the effect that restriction is moved more firmly, thereby floor 4 can not be moved to any direction of long side direction.

In addition; For example shown in Fig. 6 (D); Can dock and limit under its state that moves at an end that makes floor 4 long side directions and crossbeam etc., floor fixture 1 (1a, 1b) is installed, make floor 4 is become big towards leaving the restraint that said crossbeam direction moves; Under the situation of said structure, an end on floor 4 remains the state that docks with crossbeam.

In addition; Shown in Fig. 6 (D), when floor 4 is installed with floor fixture 1 (1a, 1b), even be used on the floor 4 at the powerful masterpiece of ultra expection; Make floor 4 all of a sudden when leaving the crossbeam direction and move, floor 4 also can automatically restore to the original position that an end docks with crossbeam.

That is, shown in Fig. 6 (E), be in to expand in floor 4 that an end leaves the crossbeam state and when distortion that size increases takes place, a little less than the power that floor fixture 1a moves than floor fixture 1b restriction.Therefore, shown in dotted line among (E) of Fig. 6, floor 4 expands with the end of the crossbeam side mode near crossbeam.

On the other hand; Shrink and size when reducing on floor 4; Because a little less than the restraint of floor fixture 1b than floor fixture 1a, so the mode that shrink with the end on right side in scheming on the floor deforms its result; Follow the expansion or the contraction on floor 4, floor 4 self also can automatically restore to the original position (position during construction) that docks with crossbeam.

Therefore, claim of the present invention is not limited to utensil, equipment, machinery, device or operation and the method that disclosed ad hoc fashion constituted here.The core or the essence of this epoch-making invention of claim intention protection.The present invention obviously has novelty and beneficial effect.

And, accomplish when of the present invention, to those skilled in the art, the present invention is not with reference to prior art and conspicuous, and has realized technical leap in view of the present invention, so the present invention obviously is the pioneering invention in this area.For through protecting core of the present invention by law, should very broadly explain claim of the present invention.
