Abstract
A button has a body (1) and a retaining post (2) for securing the body to the material, the retaining post having a portion (5) with a T-shaped cross-section. The strut (7) of the T-shaped section (5) forms a hollow cap-shaped elastic body (8) at one end far away from the transverse plate (6). The hat-shaped flange (9) on the elastic body faces the transverse plate (6). The body (1) is provided with a containing cavity formed by a blind hole (11), the section of the containing cavity is similar to the cap-shaped section of the elastic body, when the elastic body is assembled, the cap-shaped flange (9) of the elastic body (8) contracts, and the elastic body is pressed into the containing cavity with the cap-shaped section through the blind hole (11). Thereafter, the elastomer expands, locking the retention post (2) to the body (1).
Description
The invention relates to button, particularly do not need invention with the button of tailor's tack on lining.
Known have a dish type body without the fixing button of line, and the stem cover of a hollow stretches out from body, and this button also has a disc to keep post, keeps on the post cylinder along the band ripple of blowout patche and arranged vertical being arranged.This cylinder relies on friction to be installed in the stem cover.So known button must will keep post to be pressed into body with suitable power, can not make us satisfied fully by the frictional engagement that ripple produces.
The button of improvement provided by the invention can be avoided above-mentioned shortcoming.
Button provided by the invention has a body and one body is fixed to maintenance post on the lining, and keeping post that a cross section is arranged is the part of T shape.End away from transverse slat on the T shape part pillar is connected with an inner support, and this supporting member is a hollow hat elastomer, and this elastomeric hat flanged ring is around pillar and towards transverse slat.Described body has a cavity volume that has similar in appearance to the hat section, in order to hold elastomer.Firmly pack into the elastomer flange of cavity volume of cavity volume lip checkpost.When packing into, elastomer contracts; After packing into, the elastomer expansion is enclosed in the cavity volume it.The inner surface that in cavity volume, has part outer elastomeric surface contact cavity volume at least.
Following mode is desirable:
Preferably body has a plane, cavity volume by one from then on the blind hole that extends inward of plane forms, the bottom of this blind hole enlarges the described compatible hat section of formation.
Elastomeric flange has one group of V-shaped groove hole, so that elastomer can shrink in entering the blind hole process.
The T section part is made one with elastomer.
The hat elastomer shape is compatible to the hat cavity volume.
The present invention is illustrated with specific embodiment in conjunction with the accompanying drawings.
Fig. 1 is a stereogram of the present invention.
Fig. 2 is the vertical cross section of Fig. 1.
Fig. 3 is the separation graph of part shown in Figure 2.
The maintenance post detail drawing that Fig. 4 uses for the present invention.
Reference number is represented the different piece of part among the figure.
Button shown in Figure 1 has one to be used to adorn the body 1 that keeps post 2, and body has plane 3, in order to supporting lining surface (not drawing among the figure).The body opposite side is a dome-shaped outer surface 4, and its cross section is circular.Keeping post 2 is that the part 5 of T shape forms by the cross section, and the transverse slat 6 of this T shape part and the cross section of pillar 7 are circle.In the practical application, be close to the plane that does not contact of the lining that this button will invest with the lower surface of transverse slat 6 with plane 3.T body 5 is made one with elastomer 8.
Shown in Fig. 2,3,4, pillar 7 is cast an inner support away from an end of transverse slat 6, and this inner support is one and has the hollow hat elastomer 8 of the hemispherical of being roughly.Hat elastomer 8 has a circle around pillar 7 and towards the flange 9 of transverse slat 6, has one group of V-shaped groove 10 on the flange 9, so that radial contraction when allowing flange 9 pressurizeds, as shown in Figure 4.
Main reference Fig. 2 and Fig. 3 have a blind hole that extends internally 11 on the plane 3 of body 1 now, and the bottom of this blind hole enlarges and form the hat cavity volume.The shape of this hat cavity and elastomer 8 is similar, but big slightly.From this point, blind hole 11 has just formed the part of the cavity volume with die cavity similar to the calotte shape 12, and this cavity volume part can be compatible by elastomer 8.The meet of die cavity 12 and blind hole 11 forms an annular lip 13.
In actual the use,, must on lining, do an aperture that is enough to elastomer 8 is passed through, so that the inner surface of transverse slat 6 is close to lining for button is fixed on the lining.Blind hole 11 contacts follow-up pressure in keeping post 2 with the hat elastomer, flange 9 radial contraction on the elastomer 8, V-type groove closure, enter die cavity 12 up to elastomer by hole 11, the flange 9 of elastomer 8 restores to the original state, during flange 9 crouched into cavity volume lip limit 13 like this, the size of elastomer 8 and cavity volume should be able to make the hemispherical die cavity prevent that elastomer is too tight or too loose, made body and keep post to link in position reliably to go up.But the elastomer of cavity volume has similar semi-spherical shape.So that the two can rotate in relatively large angular range reliable the connection.
Button of the present invention is not only installed easily because hat elastomer 8 is arranged, and compares with the button of prior art, can hold multiple bigger strain, and the compatible shape of cavity volume can prevent that elastomer 8 from changing shape, so elastomer 8 can be fixed reliably.
Also can obtain advantage of the present invention and effect without hemispherical with other shapes, key provides a hat shaped.For example, the hat shaped of elastomer 8 can be square, and cavity volume also has similar shapes, and is compatible dimensionally.
Claims (2)
1, button comprises that a body and one are fixed to maintenance post on the lining with body, and keeping post that a cross section is arranged is the part of T shape, and the end away from transverse slat of the pillar on the T shape part is connected with the elastic expansion part; It is characterized in that, the hat that is shaped as indent of elastic expansion part, this end of pillar is connected with top in it, the flange of elastic expansion part is away from this top and point to this transverse slat, and around this pillar but contact with it of circumferential ring, this body has a blind hole, its collar extension diameter is less than the basic size of elastic expansion part, cecum in the hole is split into the hat cavity volume of an indent similar to elastic expansion part shape to accept the elastic expansion part, firmly pack into the elastic expansion part of cavity volume of cavity volume lip checkpost, when being pushed over the cavity volume inlet, flange can shrink, basic again recovery is normal in cavity volume then, and its outer surface contacts with the inner surface of cavity volume at least in part, thereby the hat part can therefrom not produced.
2, according to the button of claim 1, body wherein has a plane, and this blind hole is opened on this plane.
