1. Field of the Invention
The present invention relates to a collar stay which can be expeditiously adjusted to a variety of lengths to correspond to different size shirt collars.
2. Description of Related Art
Men's dress shirt collars come in various sizes. Typically, the dress shirts are sold with collar stays which are removable.
Adjustable collar stays have been described. U.S. Pat. No. 2,372,752 describes an adjustable shirt collar stay having arms and pivotally attached to a body that can be pivoted to vary the distance between the arms with a pin adjustably received in the body. An adjustment of the pin varies the length of the stay and an adjustment of the arms varies the width of the collar stay.
U.S. Pat. No. 2,564,008 describes a collar stiffener formed of stainless steel. A receiver part includes spaced apart arms with longitudinal slots in the lateral edges thereof. A received member has ratchet teeth to engage the arms and retain the received member at a particular position to change the length of the device. The teeth are disengaged by flexing the arms away from the slots.
U.S. Pat. No. 2,799,024 describes a collar stiffener formed of a first pointed member with two dimples and a blunt member with a vertical row of recesses. The members are formed of a flexible material such as spring brass or spring tempered Phosphor bronze. Each of the members are provided with a pair of ears to keep the two members clamped in close contact to one another to hold the members by spring pressure. The stay is extended or shortened by endwise pressure or pull on the stay. The pressure causes the members to bow with respect to each other in a region lying between the ears. The members when bowed allow disengagement of the dimples from the recesses and to allow motion of the members.
The above described collar stays use many mechanical parts and are cumbersome to adjust. It is desirable to provide a collar stay having minimal mechanical parts with low manufacturing costs. The adjustable collar stay can be readily adjusted to a precise length.
