The specific embodiment

As shown in Figure 1, one 10 comprises a peripheral frame 12, and it has a pair of

munnion

14,16 and a pair of beam 18,20.Beam 20 is near the top of door 10 and beam 18 is arranged near the bottom of door 10.Munnion 14,16 and

beam

18,20 basic fixed together, to limit the peripheral frame 12 of door 10.Peripheral frame 12 also can comprise intermediate rail 22 that are arranged in

beam

18,20 centres and extend fully between munnion 14,16.Best, intermediate rail 22 is parallel to end beam 18 and top beam 20 extends.As known technology, leader's device (not shown) can be fixed on the door 10 at intermediate rail 22 places.Beam 22 allows door 10 to be hung as the right unlatching door or door is opened on the left side.Because intermediate rail 22 is fully extended between

munnion

14,16, leader's device can be fixed on the door 10 and munnion 14 or munnion 16 position adjacent.

Best,

munnion

14,16,

beam

18,20 and intermediate rail 22 are made by wood or timber products.Door 10 is particularly suited for as interior door, and can be described as hollow door.Door 10 also comprises two plates 30,50.Each plate has the surface that can see from the outside 31,51 and is fixed to

inner surface

33,53 on the opposite flank of peripheral frame 12, as described in Figure 2.

Plate

30,50 can be fixed to peripheral frame 12, makes them toward each other.

Plate 30 comprises an outer planar area 32.From the outer planar area 32 inside wide P of asymmetric axle that form on the plate 30.Asymmetric profile P comprises a protuberance 34 and a recess 36.The given shape of protuberance 34 and recess 36 can be decided according to customer's hobby.Inwardly form an inner planar area 38 from recess 36.The thickness that surpasses recess 34 and protuberance 38 by the thickness that can find out

plane area

32 and 38 among Fig. 2.Therefore, inner planar area 38 is arranged in the periphery of asymmetric profile P, and with respect to outerplanar part 32 upcountry at interval.That is, asymmetric profile P comprises the enclosed area with respect to external surface 31.This enclosed area can be rule or irregularly shaped according to customer's hobby.For example, asymmetric profile P can limit a rectangular closed district, or asymmetric profile P can limit the enclosed area with flexure plane as shown in Figure 1.In either case, asymmetric profile P limits a ring continuous or sealing, and inner planar area 38 is arranged in the closed-loop.

Door 10 can comprise the asymmetric profile portion P above.For example as mentioned above, the door 10 among Fig. 1 comprises the asymmetric profile P that is limited by protuberance 34 and recess 36.Asymmetric profile P is arranged in door 10 top, is preferably on the intermediate rail 22, under the beam 20.In addition, door 10 comprise be arranged under the intermediate rail 22, one second asymmetric profile portion P2 on the beam 18.Asymmetric profile portion P2 can have enclosed ring and a shape different with asymmetric profile portion P.Asymmetric profile P2 is by once a protuberance 40 and a lower concave part 42 limit.Lower concave part 42 inside be planar section 44.Therefore, following asymmetric profile P2 comprises a closed-loop, and descends protuberance 40 and lower concave part 42 to comprise continuous element.

As above-mentioned door 10, the asymmetric profile of each on door 110 comprises a closed-loop protuberance one-body molded with the recess of a closed-loop and that link to each other.Each recess is partly arranged around an inner plane.For example, profile 134 comprises a closed-loop protuberance 136 that is connected to a closed-loop recess 138; An and inner plane part 140 that is wrapped.Profile 144 comprises the inner plane part 150 that the closed-loop protuberance 146 and that is connected to a closed-loop recess 148 is wrapped.

Middle asymmetric profile 154,164 comprises respectively with closed-loop recess 158,168 and being connected and integrated closed-loop protuberance 156,166.Down asymmetric profile 174,184 comprise be connected with closed-loop recess 178,188 and one-body molded, and respectively around or encase the closed-loop protuberance 176,186 of inner plane part 180,190.

As shown in Figure 3, the asymmetric profile of closed-loop is substantially elongated rectangular.But the contour structure of door 110 can be any required form and size according to customer's hobby.For example, asymmetric profile can be circle, and is square, and rectangle is irregularly shaped, or the combination of these shapes (as the asymmetric profile P among Fig. 1).For allowing suitably the door 110 that curls, and non-warping or curling peripheral frame 112, this profile must be closed-loop.Each profile comprises a protuberance, is connected to a recess of protuberance, and an inner plane part that is wrapped.

Best, the plate 130 of positioned opposite is fixed on the frame 112, makes that plate 130 is corresponding from cross section (shown in the door 10 Fig. 2).Therefore, plate 130 is fixed to frame 112 to be similar to door 10 described modes.In addition, as above-mentioned, door 110 also comprises the flat board between the pair of panel 130 between the corresponding inner plane part of another plate 130 of being fixed on inner plane part 140,150,160,170,180,190 that is wrapped and a relative side that is fixed to frame 112.In addition, door 110 grain patterns that also can comprise as shown in Figure 3.

As shown in Figure 4, the third embodiment of the present invention is arranged one 210, and it has a lock dog (lock block) 222 that is fixed to a munnion 214 with respect to intermediate rail of fully extending or lock beam between (in the door 10 and 110) vertical munnion.One second lock dog (not shown) can be fixed on the relative munnion on the opposite face of door 210.Except saving an intermediate rail of extending fully between the munnion, and comprise outside at least one lock dog 222 that the structure of door 210 is identical with described 10 and 110 relatively.Be provided with two lock dogs, door 210 can have the locking device on arbitrary that is fixed on door 210.

Therefore, door 210 comprises a complete peripheral frame 212, and it comprises the munnion of fixing with lock dog 222 214.A pair of outside plate 230,250 is fixed to the opposite face of frame 212.For ease of discussing, plate 230 is one " preceding " plate, and plate 250 is one " back " plate.Described in

door

10 and 110, plate 230,250 is corresponding mutually.Plate 230 comprises an outer perimeter planar area or part 232, and plate 250 comprises an outer perimeter planar area or part 252.Neighboring part 232,252 suitably is fixed to frame 212, and lock dog 222, and the relative lock dog 222 on relative munnion (not shown).

The asymmetrical design of plate 230 or part comprise a protuberance 234 and a recess 236, as above-mentioned.The asymmetrical design of plate 250 or profile comprise a protuberance 254 and a recess 256.This recess and the protuberance of plate align mutually, as mentioned above, and shown in the door 10 among Fig. 2.

Protuberance and recess extend on the whole length of plate 230,250 continuously, and inwardly arrange from neighboring part 232,252 respectively.Therefore, protruding element and recessed element, the shorter closed-loop comparison with

door

10 and 110 has quite long closed-loop.The centre or the lock beam of horizontal expansion are not set, and door 210 can have the asymmetric part of this complete length on plate 230,250.

Each plate 230,250 comprises the inner planar area adjacent with the recess of plate, as mentioned above.For example, plate 230 comprises an inner plane part 238, and plate 250 comprises an inner plane part 258.One flat board 270 can be fixed between the inner plane part 238,258.As mentioned above, dull and stereotyped 270 opposite houses provide stability.Dull and stereotyped 270 can extend in the asymmetric profile of the door 210 adjacent with recess 236,256 fully, and can response temperature and the situation of humidity and the curling of asymmetric part of limiting alignment.

Some feature of the present invention at the specific embodiment explanation as above.Yet, be familiar with this technology personage as can be known do not depart from the scope of the present invention and spirit under can do various improvement and change.Therefore, the present invention includes these improvement and changes in claim, and fall in the scope of the claim of enclosing and homologue.
