Straightening tool

This clever brush requires absolutely no styling skills to transform your hair into smoother strands , plus it won't sacrifice volume at the root or give hair that crunchy, too-straight look. Don't expect it to get your hair as pin-straight as it might with a traditional straightening iron, but we recommend using it whenever hair is misbehaving but doesn't need to be stick-straight. It slashed one of our curly-haired editor's straightening time in half. Reviewers say it can press hair silky smooth in one pass, cut down on styling time, and is snag-free.

In our Beauty Lab tests, however, it scored low for ease of use and satisfaction with testers citing the heat dial as "difficult to adjust," plus it took the longest of all irons to heat up — we also found hair didn't remain straight. Product Reviews. Home Ideas.

It is a further object of this invention to provide such a pin straightening tool which is simple to use. It is a further object of this invention to provide such a pin straightening tool which easy to manufacture.

It is a further object of this invention to provide such a pin straightening tool which is cost effective to manufacture. It is a further object of this invention to provide such a pin straightening tool which prevents scrapping of expensive electronic modules.

It is a further object of this invention to provide such a pin straightening tool which, if used correctly, ensures that the connector pins are straight and provides feedback to the user when a bent pin is properly straightened and concentrically located in its receptacle. The invention results from the realization that a more precise and easier to use pin straightening tool is effected by a a shaft terminating in an end assembly with an outer diameter slightly less than the inner diameter of the receptacle housing the pin and fashioned with an inner cam shaped wall or collar which surrounds the connector pin and which straightens and also concentrically aligns the pin in the receptacle as the shaft is rotated, and b a bore adjacent the cam shaped wall or collar into which the pin is received and straightened when the pin is concentrically aligned thus providing a positive feedback to the operator that the pin is now straight.

This invention features a pin straightening tool comprising a shaft terminating in an end assembly and a chamber in the end assembly for receiving a bent pin therein. The chamber terminates in a shelf inside the end assembly and there is a bore located in the chamber for straightening the bent pin as the shaft is rotated urging the distal end of the bent pin into the bore.

In a preferred embodiment, the bore is located in the center of the end assembly and the chamber is located eccentrically with respect to the center of the end assembly. Also in the preferred embodiment, the chamber includes a gap therein forming two opposing longitudinally extending edges which can be driven behind the bent pin. The bore typically has a rearward side abutting a rearward edge of the shelf.

In one example, the bore has a diameter slightly greater than the diameter of the pin, the chamber has a diameter much larger than the diameter of the bore, the chamber has a depth less than the length of the pin, and the depth of the bore when added to the depth of the chamber totals a length greater than the length of the pin.

In the preferred embodiment, the end assembly includes a first reduced diameter portion receivable in the receptacle containing the pin therein. The first reduced diameter portion has an outside diameter less than the inside diameter of the receptacle and the chamber is located in the first reduced diameter portion.

Preferably, the end assembly further includes a second reduced diameter portion also receivable in the receptacle containing the pin. The outside diameter of the second reduced diameter portion is slightly less than the inside diameter of the receptacle.

In this embodiment, the bore extends into second reduced diameter portion. The second reduced diameter portion preferably has a length less than the depth of the receptacle, and the second reduced diameter portion defines a shoulder on the end assembly larger in diameter than the receptacle.

There may also be a sloping wall between the first reduced diameter portion and the second reduced diameter portion for aligning the second reduced diameter portion in the receptacle.

In one example, the shaft includes a knurled finish for gripping thereof, the shaft is round, and the end assembly is round. One pin straightening tool in accordance with this invention includes a shaft terminating in an end assembly receivable in a receptacle containing a bent pin, a cam surface inside the end assembly configured to urge the distal end of the bent pin into a straight configuration, and a bore which receives the distal end of the bent pin therein when it is urged into the straight configuration by the cam surface.

Typically, the cam surface is the interior wall of a chamber formed in the end assembly. This chamber may terminate in a shelf inside the end assembly. Preferably, the bore is located in the center of the end assembly and the chamber is located eccentrically with respect to the center of the end assembly. In addition, the chamber may include a gap therein forming two opposing longitudinally extending edges which can be driven behind a bent pin.

The pin straightening tool of this invention may include a shaft terminating in an end assembly having a first distally located reduced diameter portion and a second larger reduced diameter portion adjacent the first reduced diameter portion, a chamber in the first reduced diameter portion terminating in a shelf, the chamber having a gap therein forming two opposing longitudinally extending edges which can be driven behind a bent over pin, and a bore located in the shelf and extending into the second reduced diameter portion for straightening the bent pin as the shaft is rotated forcing the distal end of the bent pin into the bore.

A pin straightening tool in accordance with a preferred embodiment of this invention comprises a shaft terminating in an end assembly, a chamber in the end assembly terminating in a shelf therein, the chamber having an interior wall defining a cam surface terminating in a gap forming two opposing longitudinally extending edges receivable in a receptacle containing a bent pin therein, and a bore abutting the interior wall of the chamber for receiving the bent pin therein as the tool is rotated, as one longitudinally extending edge moves behind the bent pin, and the cam surface urges the bent pin into the bore.

In one example, there is a shaft, a collar portion on a distal end of the shaft which urges the pin into a concentric relationship inside the receptacle, and a bore which receives the distal end of the pin therein as the collar portion is rotated. Typically, the collar portion is defined by a reduced diameter distal end of the shaft, and an opening in the reduced diameter distal end of the shaft in communication with the chamber.

Other objects, features and advantages will occur to those skilled in the art from the following description of a preferred embodiment and the accompanying drawings, in which:.

Pin 14 , in one example, is only 0. Bore 20 of plug 18 receives pin 14 therein when plug 18 is forced into receptacle As delineated in the Background section above, however, pin 14 , FIG. In the prior art, tweezers or even tool 30 , FIG.

Unfortunately, tool 30 cannot be effectively used if pin 14 is severely bent and, even if pin 14 is only slightly bent, tool 30 does not always result in a straight pin or worse, can result in a broken pin in which case the electronic module may have to be scrapped resulting in an unfortunate waste.

The other problems associated with tweezers and prior art tool 30 are delineated in the Background section above. Pin or center conductor straightening tool 60 , FIG. Handle end 66 may include knurled surface Orifice 70 may also be included through handle end 66 and used for tethering tool 60 to a workbench where electronic components with center pin connectors are being assembled or tested.

A prototype tool 60 was made of metal, was 1. In this same example, end assembly 64 includes first reduced diameter portion 72 which is 0. Second reduced diameter portion 74 is 0. Sloping wall 76 joins first reduced diameter portion 72 with second reduced diameter portion Shoulder 78 is present between second reduced diameter portion 74 and third reduced diameter portion 79 and acts as a positive stop since third reduced diameter portion 79 is too large e.

These dimensions are specifically tailored, in this example, for a GPO connector 0. Those skilled in the art, however, will understand how to tailor these specific dimensions for connectors of other configurations and dimensions.

Sloping wall 76 assists in guiding second reduced diameter portion 74 into the connector receptacle to a maximum depth defined by shoulder Also in the preferred embodiment, the total length of end assembly 64 is approximately equal to, or slightly less than the depth of the receptacle. In the above example, the length of end assembly 64 is 0. As better shown in FIGS. Pin straightening bore 84 is preferably located in chamber 80 and begins at shelf 82 and extends into second reduced diameter portion In the preferred embodiment, bore 84 is located in the center of end assembly 64 but the center of round chamber 80 is located eccentrically with respect to the center of end assembly In other words, the longitudinal axis of bore 84 is disposed along the longitudinal axis of the tool.

The longitudinal axis of round chamber 80 , however, is parallel to but displaced from the longitudinal axis of the tool. Chamber 80 , in the example started above, is 0. In general then, chamber 80 has a depth less than the length of the pin to be straightened and the depth of bore 84 , when added to the depth of chamber 80 , totals a length slightly greater than the length of the pin to be straightened.

Preferably, chamber 80 has or defines a gap 90 , FIGS.
