Shown in Fig. 1,2 and 5, framework 12 comprises the lateral frame member 52 on the main body 50 of holding cushion 14 and each side that is arranged on main body 50.Each lateral frame member 52 comprises first connector part 24 integrally formed with it.Shown in Fig. 5-7, first connector part 24 comprises locking folder receiver assembly 54.Locking folder 28 is configured to and locks 54 interlockings of folder receiver assembly with removably attached locking folder 28, and then attached headwear assembly is to framework 12.
Each locking folder receiver assembly 54 comprises that 56 and two of a slit (slot) with a mid portion 58 is positioned at the lock part 60 on the opposite side of mid portion 58.The mid portion 58 of slit 56 has upper surface 62, and upper surface 62 is continuities of the upper surface 64 of each lock part 60.Yet 66,68 and two lock parts 60 of the lower surface of mid portion 58 have ladder-shaper structure respectively.Especially, as illustrated in Figures 5 and 6, mid portion 58 has thereon the height h2 between surface 62 and the lower surface 66.Two lock parts 60 have the height h1 between the surface 64 and lower surface 68 thereon.In the embodiment of expression, height h2 is greater than height h1.In addition, the height h2 of mid portion 58 is approximately equal to the height h2 of intermediate supports protuberance 42, and the height h1 of two lock parts 60 is approximately equal to the height h1 of the previous section of each spring arm 36.This configuration makes locking folder 28 and locking press from both sides the ease of connection between the receiver assembly 54, as will further being discussed.
As shown in Figure 7, each lock part 60 comprises the lock flange 70 that is positioned on its outer wall, is used for locking protuberance 38 engagements with locking folder 28.
In the embodiment of expression, first connector part 24 is together integrally molded with framework 12.Shown in Fig. 5 and 10, framework 12 also comprises a hole 80 and the axle collar (collar) 82, and the axle collar 82 is suitable for holding turning gland 22 (Fig. 1 and 2).The wheel rim 84 that the axle collar 82 has from the hole 80 levels and radially extends.In order to form the axle collar 82, if mold can flatly be deviate from, this is favourable so.Yet the expectation headwear occurs with an angle with respect to framework 12.First connector part 24 is adjusted downwards with approximate 5% angle θ with respect to level.When framework 12 was molded, moulding part should be regained in the horizontal direction, formed the axle collar 82.As shown in Figure 7, at the lower surface 66,68 of mid portion 58 and the joint between the lock part 60, be arranged the formation angle [alpha] respectively, it is enough wide for angle [alpha], can make the limit of mold deviate from the horizontal direction.Again, angled joint makes at locking folder 28 and locks the ease of connection of pressing from both sides between the receiver assembly 54.
As shown in Figure 9, the previous section 34 and the aft section 32 of locking folder 28 are relative to each other arranged with angle beta.In the embodiment of expression, with respect to level, aft section has an angle down, and previous section 32 is adjusted to level usually.By using this angle, locking folder 28 is not outstanding from face shield.And the headwear belt is connected to locking folder 28 with an angle, and it is consistent with the profile of face more naturally.In a replacement form of the present invention, front and back part 34,32 can be crooked to obtain in front and a differential seat angle between the back.The advantage of both methods is: the slit 56 that enters first connector part 24 of the previous section 34 of holding second adapter slidably can be level usually.This is favourable during manufacture process, because this means: the limit of mold can flatly be regained, and helps to form the axle collar 82.
Shown in Fig. 8-9, the lock part 60 of slit 56 is suitable for holding in a pair of spring arm 36, the locking protuberance 38 of each spring arm 36 presss from both sides 28 with lock flange 70 interlockings in the lock part 60 that is arranged on separately with removably attached locking, and then attached headwear assembly is to framework 12.When locking folder 28 inserts in the locking folder receiver assemblies 54 so that the additional support to locking folder 28 to be provided, shoulder of each locking folder 28 divides 40 engagements to be arranged on the field of conjugate action 74 on the framework 12.Locking protuberance 38 can with undercut portions (undercut) interlocking that in lock part 60, is provided with, press from both sides 28 and be attached to framework 12 thereby removably will lock.Again, each locking protuberance 38 can extend by the slit in the outer wall that is arranged on lock part 60.Slit needn't extend by the outer wall of lock part 60.
When locking folder 28 and 54 engagements of locking folder receiver assembly, intermediate supports protuberance 42 is inserted in the mid portion 58 of slit 56, thereby prevents to lock relatively moving between folder 28 and the locking folder receiver assembly 54.
Especially, when locking folder 28 is inserted in the locking folder receiver assembly 54, because locking protuberance 38 inserts in each lock part 60 of slits 56, and ride up and surpass lock flange 70, so spring arm 36 is mutually in the face of applying power (according to the direction of as shown in FIG. 3 arrow A).In case locking protuberance 38 has been skipped each lock flange 70, spring arm 36 is bullet (according to the opposite direction of as shown in FIG. 3 arrow A) outwards, to provide locking mesh locking between protuberance 38 and the lock flange 70.In the lock part 60 of slit 56, provide enough gaps, allow for and skip moving of lock flange 70 necessary locking protuberances 38.
Intermediate supports protuberance 42 is configured to have and the closely cooperating of the mid portion 58 of slit 56, make: when the centre is supported protuberance 42 and is inserted in the mid portion 58, between locking folder 28 and locking folder receiver assembly 54, allow rotation in a small amount, shake or parallel moving.Intermediate supports protuberance 42 is longer to help to be registered to slit 56 than spring arm 36.Again, wall 72 engagements in the groove of intermediate supports protuberance 42 44 and the mid portion 58 that is arranged on slit 56, it is easy to make that intermediate supports protuberance 42 enters the mid portion 58 of slit 56.As selection, intermediate supports protuberance 42 can have and the ledge that is arranged on the engagement in the mid portion 58 of slit 56.Again, intermediate supports protuberance 42 has a complementary shape of angle [alpha] with the shape of the mid portion 58 of definite slit 56.
Because the height h2 of mid portion 58 is approximately equal to the height h2 of intermediate supports protuberance 42, and the height h1 of two lock parts 60 is approximately equal to the height h1 of the previous section of each spring arm 36, so there are enough height the lock part 60 of slit 56 to hold the previous section of each spring arm 36, still is not enough to hold intermediate supports protuberance 42.That is, intermediate supports protuberance 42 is too thick so that can not be fixed in the lock part 60 of slit 56.Because this configuration, whether locking folder 28 will be clearly with 54 engagements of locking folder receiver assembly correctly concerning patient.Therefore, patient can attentively partly will lock folder 28 in the mode that can unclamp once in a while and be assembled to locking folder receiver assembly 54.For example, Figure 11 is expression locking folder 28 first outs of position with respect to locking folder receiver assembly 54, and Figure 12 is expression locking folder 28 second outs of position with respect to locking folder receiver assembly 54.In the two situation, patient can not be inserted into thicker intermediate supports protuberance 42 in the thin lock part 60 of slit 56.
As shown in FIG. 8, locking folder 38 and middle protuberance 42 have circular or isocontour edge, make that to enter slit 56 easy.Again, preferably, the surface outwardly of locking folder 28 and framework 12 preferably forms a common coextensive continuous surface, and it does not interrupt when connecting.Preferably, locking folder 28 is the same wide with lateral frame member 52, and this makes feels locking by patient to press from both sides 28 position easy.
An advantage of headwear coupling assembling 20 is: locking on being provided in each lateral frame member 52 folder receiver assembly 54, can use a locking folder 28, and therefore, reduce manufacturing cost and to stock's demand.
Figure 13-20 further is illustrated in the constitutional detail of the different size among the embodiment of locking folder 28 of headwear coupling assembling 20.For example, locking folder 28 has the length of 20-40mm scope, is preferably 29mm, and the width of 20-40mm scope is preferably 27.8mm, and the height of 4-8mm scope, is preferably 6.7mm.In the embodiment of a locking folder 28, in Figure 13-20 size of expression can change ± 10%.
In the embodiment of explanation, the aft section 32 of locking folder 28 comprises a cross bar 46 that forms an opening 48, and by it, the belt of headwear assembly can removably be coupled with cross bar 46.In other form of the present invention, use other mechanism to connect the belt of headwear assembly.For example, belt can comprise a hook, and hook meshes with the corresponding hole in the locking folder.In another form, belt is sewn to a place and is not removable.In another form, belt is removable, and, remain on a position by friction fit.
