摘要:
The operating device, in particular for a vehicle component, is provided with a rotary operating element (18), which can be rotated about a rotation axis (20) and is formed as a plastic injection-molded part, which is produced in a molding die (48) having a die separation plane (46), and with a bearing unit (12), on which the rotary operating element (18) is mounted such that it can rotate about the rotation axis (20). The bearing unit (12) has a first bearing element (14), which is formed as a plastic injection-molded part, which is produced in a molding die (28) having a die separation plane (34). The first bearing element (14) has a bearing surface (26), which extends in a radial plane to the rotation axis (20) and concentrically to same, and the rotary operating element (18) has a contact surface (36), which bears against the bearing surface (26) and likewise extends in a radial plane to the rotation axis (20) and concentrically to same. Either the bearing surface (26) of the first bearing element (14) or the contact surface (36) of the rotary operating element (18) is arranged outside the die separation plane (34; 46) of the injection-molding die (28; 48) for said relevant element (14; 18), and the other of the two surfaces (26; 36) is arranged in the die separation plane (34; 46) of the injection-molding die (28; 48) of said relevant element (14; 18).

An envelope is provided with a first and second button having a depending portion inserted through an opening in a flap and an adjacent body portion, respectively, which is then flattened by the application of ultrasonic energy to vibrate each button and its depending portion against an anvil, rendering each button captive on the envelope. A string is inserted through a slot or hole in the depending portion of one of the buttons and fused to the button as the depending portion is flattened. The string is used to releasably connect the buttons and thus, the envelope flap to the adjacent body portion.

A method for manufacturing a lighting button key is provided. The method includes forming a button body by processing a metal plate, attaching a thin film to the button body and performing double etching on a rear surface of the button body to process a symbol pattern. Additionally, the method includes press-forming the rear surface of the button body and an injection material of a transparent or translucent material into the rear surface of the button body to perform injection molding.
摘要:
A method of fastening a button or the like to a garment such that the garment will be buttoned up after the fastening operation, wherein said button is composed of plastic and initially comprises a button head and a stem projecting from the button head, the stem having an outer end for piercing the garment and for deformation by ultrasonic vibration, a central section characterized by a substantially smooth profile, and an inner section flaring into the button head, the method comprising the steps of: providing a button hole in a first portion of the garment; placing said first garment portion in an overlying relation with a second portion of the garment; positioning said button such that the button head is disposed on the side of said first garment portion opposite to said second garment portion and such that the stem extends through the button hole and pierces at least partly through said second garment portion; and deforming the outer end of the stem by ultrasonic vibration thereof. A machine for practising the method is also disclosed.
摘要:
A method and apparatus for securing buttons to fabric. The method comprises providing a button with a thermoplastic portion and securing the button to fabric by applying ultrasonic energy to the thermoplastic portion which enables securement between the button and the fabric by the flowing of the thermoplastic portion into the fabric.

A button-fastening upper die includes a die body, a button-holding member and a cylindrical elastic member arranged between the die body and the button-holding member. By providing the elastic member with an annular recess recessed radially outward from the inner surface e.g. at the middle of the surface, the elastic member is sectioned into a thin-walled section located radially outward from the recess and two or more thick-walled sections remaining above and below the recess and the thin-walled section.
