Abstract
Description
- This invention relates to improvements in and relating to a grommet made of a resilient material which is to be set in sheet material such as a garment fabric.
- There are known a variety of grommets made of metal or plastics to be set in sheet material such as of textile articles. The grommet usually comprises an eyelet to be pierced through the sheet material and a washer to be coupled with the eyelet, in which instance the eyelet is curled or otherwise deformed so as to fit securely over the washer. Prior to this coupling or clamping operation, the washer is often liable to get loose and fall apart from the eyelet, requiring the user to hold these parts together all way until the moment they are clamped into place by a tool.
- According to the invention, there is provided a grommet which comprises: an eyelet made of a resilient material and including a cylindrical barrel with one end open, an annular flange extending around the other end of said barrel; a washer made of a resilient material and including a circular plate having a central bore which has a diameter nearly equal to the outside diameter of said barrel; and a means for retaining said eyelet in engagement with said washer temporarily until they are assembled into a grommet.
- It is an object of the invention to provide an improved grommet which comprises an eyelet part, a washer part, both of which are to be coupled together with a sheet material interposed therebetween, and a means for retaining the eyelet and the washer in engagement temporarily until they are finally assembled in the form of a grommet.
- The features and advantages of the present invention will be better understood from the following description taken in conjunction with the accompanying drawings in which preferred structural embodiments incorporating the principles of the invention are shown by way of example.
-
- Figure 1 is an exploded, cross-sectional view of a grommet embodying the invention, with an eyelet, a sheet of fabric and a washer arranged in this order;
- Figure 1A is a cross-sectional view of a modified form of the eyelet;
- Figure 2 is a cross-sectional view of the grommet of Figure 1 which has been assembled and set in the fabric;
- Figure 3 is a view similar to Figure 1 but showing a modified form of grommet embodying the invention;
- Figure 4 is a cross-sectional view of the grommet of Figure 3 which has been assembled and set in the fabric;
- Figure 5 is a plan view of the eyelet taken along the arrowed lines V-V of Figure 3; and
- Figure 6 is a plan view of the washer taken along the arrowed lines VI-VI of Figure 3.
- Referring now to Figure 1, there is shown a preferred form of
grommet 10 which is made up from aneyelet part 11 and awasher part 12, both parts being made of a resilient, deformable material such as plastics, rubber and the like. Theeyelet 11 includes acylindrical barrel 13 with one end open and anannular flange 14 extending around the other end or bottom of thebarrel 13. Theannular flange 14 has atapered prong 15 for biting engagement with a sheet of fabric F. - According to an important feature of the present invention, there is provided a
retaining means 16 for preventing thewasher part 12 from falling off from theeyelet part 11 once both parts have been brought into engagement. - The
retaining means 16 is embodied in the form of a plurality of discrete projections projecting radially outwardly from thebarrel 13 and arranged around thereof. Eachprojection 16 has afirst surface 16a obtusely slanting toward theflange 14 and asecond surface 16b acutely slanting toward the open end of thebarrel 13 or in a direction opposite to theflange 14. Alternatively, the retaining means may be in the form of an integral annular projection 16' (Figure lA) of the same cross section as that of the discrete projections of Figure 1. - The
washer part 12 is in the form of a circular plate having acentral bore 17 which has a diameter nearly equal to the outside diameter of thecylindrical barrel 14 and slightly smaller than an outside diameter defined by theprojections 16. Aprong 18 similar to theprong 15 extends from the bottom of thewasher 12 and similarly functions to anchor the fabric F against movement. - Now, when assembling the
eyelet 11 and thewasher 12 together, theeyelet 11 is first inserted with itsbarrel 13 through an opening Fl in the fabric F and then through thebore 17 of thewasher 12, when thewasher 12 undergoes elastic deformation as the peripheral wall of thebore 17 rides over and past theprojections 16. Thewasher 12 can thus be retained in engagement with theeyelet 11 between the fabric F and theprojections 16 until the two grommet parts are assembled in the well known manner as illustrated in Figure 2. - Referring to Figures 3-6 inclusive, there is shown a modified form of grommet which is identical in construction with the above described
grommet 10 except for the details of a retaining means embodying the invention and except that there are provided a plurality ofprongs eyelet 11 and thewasher 12, respectively, and that anannular recess 21 is formed in and around the outer periphery of thebarrel 13 of theeyelet 11 at the open end thereof to facilitate the insertion of theeyelet 11 through the fabric F as well as thewasher 12. The modified form of retaining means comprises a plurality ofradial projections 19 extending radially inwardly from the peripheral edge of thebore 17 in thewasher 12 and each having atapered surface 20 directed toward theeyelet 11. The diameter defined by theradial projections 19 is slightly smaller than the outside diameter of thebarrel 13, so that when theeyelet 11 is inserted through thebore 17 of thewasher 12, theradial projections 19 are flared up in contact with the outer wall of thebarrel 13 in a direction in which theeyelet 11 is inserted and lock thewasher 12 against backward movement, thus preventing accidental separation of thewasher 12 from theeyelet 11. Because of the structural features of theradial projections 20, theeyelet 11 and thewasher 12 upon being assembled as shown in Figure 4 can be retained in position against relative movement, thus ensuring firm setting of thegrommet 10 in the fabric F.
