ADJUSTABLE HEADWEAR
There is provided headwear comprising, a crown defining an opening for receiving a head of a wearer, an actuator configured to receive an application of a force, and a force transmission member coupled to the actuator. The actuator is configured to effect, when a head is received within the crown, and relative to the head received within the crown, a change in disposition of the force transmission member to any one of a plurality of conditions in response to an application of force to the actuator, wherein, in at least one of the plurality of conditions, an operative surface of the force transmission member is bearing against a surface fraction of the head received within the crown. The surface fraction of the head extends substantially continuously from: a point within a first distance of about two inches from a first temple reference plane defined by one of the temples of one side of the head and rearwardly towards the rear of the head, about the rear of the head and towards the other side of the head, and to a point within a second distance of about two inches from a second temple reference plane defined by the other one of the temples of the other side of the head, wherein the first distance is measured along an axis normal to the first reference plane and wherein the second distance is measured along an axis normal to the second reference plane. In each one of the at least one of the plurality of conditions where the operative surface is bearing against a surface fraction of a head received within the crown, the bearing of the operative surface against the surface fraction of the head is limited to a surface fraction disposed rearwardly of the forehead.
This invention relates to headwear and, in particular, to adjustable headwear.
BACKGROUND OF THE INVENTIONHead size varies from person to person. In supplying headwear to the marketplace, headwear manufacturers must make headwear available to accommodate persons of different head sizes. In this respect, headwear manufacturers provide adjustable headwear which is suitable for use by wide segments of the headwear wearing population.
U.S. Pat. No. 5,331,687 issued to Kronenberger discloses a size adjustable headwear piece includes an actuator with a dial which is manually rotatable to effect a change in size of the opening of the crown. Amongst other things, the actuator of Kronenberger is disposed within the sweatband, which renders manufacture of the headwear piece difficult.
U.S. Pat. No. 5,433,648 issued to Frydman discloses a rotatable closure device for hats which includes a spool for drawing in and taking up twine. The twine is coupled to the cap base, such that the drawing in action causes the cap base to decrease in size in order to accommodate smaller head sizes. Amongst other things, the twine of the device in Frydman tends to effect an undesirable degree of bunching fabric as the twine is drawn in and taken up by the spool.

Referring to
To assist in understanding the described embodiments, the terms “first temple reference plane” and “second temple reference plane” are defined as follows. Referring to
The following discussion and associated figures describe the headwear 10 as having the form of a baseball cap. The concepts and features of the headwear 10 may be applied to a wide variety of headwear 10 types. Examples of such headwear 10 types include baseball caps (full-back and open-back), fedoras, “engineer”-type hats, “ivy”-type hats, “newsboy”-type hats, bucket hats, visors, and knitted hats.
The spatial disposition of certain elements of the headwear 10 are sometimes described relative to a head of a person received within a crown 26 of the headwear 10, or relative to other elements of the headwear 10, or relative to each other. It is intended to describe such spatial disposition when the headwear 10 is being worn in its intended position relative to the head 14 of a wearer. As well, terms such as “front”, “rear”, “side”, “above”, or “below” are also sometimes used to describe the disposition of elements of the headwear 10. Such terms are intended to refer to the disposition of the element relative to a head 14 of a person wearing the headwear 10, or relative to another element of the headwear 10, when the headwear 10 is being worn in its intended position relative to the head 14 of a wearer. For example, with respect to a baseball cap-type of headwear 10, the baseball cap is intended to be worn with its visor 30 extending forwardly relative to the forehead, even though the baseball cap may be worn with the visor 30 extending rearwardly or to one side.
For example, with respect to the headwear 10, the headwear 10 includes a crown 26, and the crown 26 is of a generally hemispherical form configured for the covering of a head 14 of a person.
For example, with further respect to the crown 26, the crown 26 includes a plurality of panels 28 (or gores) that are attached together along respective and abutting sides. For example, each of the panels 28 is made from flexible material. Also, for example, the panels 28 may be made from relatively inflexible material. With respect to the flexible material, for example, the flexible material is textile. For example, a suitable textile is fabric. For example, the flexible material can be made from a blend of weaveable fibers. For example, the flexible material is 100% wool. For example, the flexible material includes an elastic component, and the elastic component is characterized as being resilient. For example, the elastic component is spandex which is weaved into the flexible material. For example, the flexible material includes from 0 vol. % to 5 vol. % of elastic component based on the total volume of the flexible material. For example, the elastic component is disposed substantially uniformly throughout the flexible material.
For example, the attachment of the panel 28 is effected by the stitching together abutting sides of the panel 28 to define seams. For example, seam tape 70 may be applied to the interior surface across and joined to abutting panels 28 to reinforce the seams between panels 28. For example the seam tape 70 is stitched to each one of a respective one of each pair of abutting panels 28. For example the seam 70 includes the same material as that used for the panels 28. For example, with respect to each of the panels 28, the thickness of each of the panels is from one (1) millimetre to two (2) millimetres.
For example, with respect to the headwear 10, the headwear 10 further includes a peak 30. The peak 30 is attached to a front portion 32 of the crown 26 and extends forwardly of the crown 26. In this respect, the headwear 10 including a peak 30 is configured to be worn on the head 14 of a human such that the peak 30 extends forwardly relative to the face of the human. For example, with respect to the attachment of the peak 30 to the crown 26, the peak 30 is attached to the front facing portion of the crown 26 by sewing the peak to the front facing crown portion along and proximate to the bottom edge of the front facing crown portion. The lower edge of the front facing portion is folded inwardly along the length of the lower edge. A stiffening or reinforcing tape is then laid over the fold, and the peak 30 is then stitched along and proximate to the edge formed by the fold.
For example, with respect to the peak 30, the peak 30 includes material which is relatively more rigid than the crown portion to which the peak 30 is attached. For example, as is typical with peaks, the relatively more rigid material is a pre-molded and cut plastic form with a material sheath pulled over it.
For example, with respect to the crown portion attached along a rear edge 34 of the peak 30, from one side 31a of the peak 30 to the other side 31b of the peak 30, the crown portion includes a material band 36 disposed immediately above the peak 30. For example, the material band 26 is made from any one of: terry cloth, wicking fabric, cotton, wool, foam, and thick interface material. For example, nanomaterials can be added as a treatment to these materials.
The adjustment system includes an actuator 38 and a force transmission member 40. The force transmission member 40 includes an operative section 44 including an operative surface configured for bearing against a surface fraction of a head received within the crown 26.
The actuator 38 is configured to receive an application of a force effected by a human hand. For example, the actuator 38 is coupled to the crown 26. Further details of an embodiment of the actuator 38, and its relationship to the force transmission member 40, are set out on below.
Referring to
For example, with respect to the effect on the force transmission member 40 of applying a force to the actuator 38, while changing a condition of disposition relative to a head 14 received within the crown 26 in response to the application of force to the actuator 38, the force transmission member 40 changes position (or moves) relative to the actuator 38. Each of
It is understood that bearing of the force transmission member 40 against a surface function of a head 14 received within the crown 26 does not necessarily require that the force transmission member 40 be in direct contact with the head 14. The bearing of the force transmission member 40 effects mounting of the headwear 10 to the head 14 in a desired position (but not necessarily a permanently fixed position, and it is understood that application of relatively minor forces to the headwear, such as that which may be applied by a human hand, may be sufficient to dislodge the headwear from the desired position) relative to the head.

For example, the tubular member 66 is formed as follows. A textile sheet is cut in a long narrow length and is 6.35 to 7.62 centimetres in width. An access slit is provided on one side of the textile sheet, and this functions as the aperture 72 to facilitate coupling of the force transmission member 40 to the actuator 38.
Referring to
In an alternative embodiment, and referring to
For example, with respect to the relationship between the force transmission member 40 and the guide system 64, the force transmission member 40 co-operates with the guide system 64 during movement of the force transmission member 40 (in response to an application of force to the actuator 38) such that vertical movement of the operative force transmission member section 44 is limited during movement of the force transmission member 40 relative to the actuator 38. For example, with respect to the limiting of the vertical movement of the operative force transmission member section 44, at least a fraction of the operative force transmission member section 44 is disposed relative to the guide system 64 such that a clearance is defined for limiting vertical movement of any fraction of the operative force transmission member section 44 within a range.

The strap 56 may comprise one or more strap pins 1060. In some embodiments the strap pins 1060 may be a pointed piece of wood, metal, or plastic. In some embodiments the strap pins 1060 may be a short rod. In some embodiments, the strap pins 1060 may be projections, teeth grooves, channels, and/or other variations and combinations. The strap pins 1060 include the actuator coupling portion 46.

The use of cam spirals 1041 may allow the strap 56 to self-lock into the cam assembly 1030 at certain contact angles. Logarithmic spirals may allow the strap pins 1060 on the strap 56 to be pulled at a linear velocity and constant contact angle. Different materials may also be used to vary the friction coefficients and make the system self-locking. Self-locking may allow the strap 56 to remain in the same position in the cam assembly 1030 when outwards forces and/or inwards forces are applied to the cam 1040 and/or strap 56. When logarithmic cam spirals are used, a constant angle of contact may be maintained with the strap pins 1060 on the strap 56, resulting in a self-locking system that may be infinitely adjustable, and one where the torque felt by the knob 1042 may be constant. However, an Archimedean spiral may be used to vary the contact angle, such as by continuously decreasing it.
The self-locking mechanism may be determined by the contact angle 1045 and the friction applied to the circumference of the cam spirals 1041 on the cam 1040. The contact angle 1045 may correspond to an angle between lines tangent to a strap pin 1060 and a cam spiral 1041. In some embodiments, the contact angle 1045 of a self-locking mechanism may be less than 20 degrees, and less than 15 degrees. In some self-locking embodiments, the contact angle is between 10 and 12 degrees. Low contact angles may allow the cam assembly 1030 to be self-locking and continually adjustable both inwards and outwards. Various contact angles can be generated depending on the speed of wind and power desired. Larger contact angles 1045 may result in faster insertion speed. Other secondary frictional elements can also be added to resist the turning of the cam 1040. In some embodiments, these secondary frictional elements may be “stepless” to maintain infinite variability of position.
In some embodiments, the strap 56 may have a chamfer 1062 on the first strap pin closest to the cam assembly insertion end 1063, to allow the first strap pin to skip past the cam 1040. The chamfer 1062 may be at a range of angles, including 45 degrees. The chamfer 1062 may also maintain engagement between the cam 1040 and the strap 56 to ensure that they continue to function. In some embodiments, a chamfer 1062 may be on other strap pins 60, including the last strap pin furthest from the cam assembly insertion end 1063 of the strap 56. In some embodiments, a chamfer 1062 may be included on the last strap pin, in addition to, or in lieu of, being on the first strap pin.
In some embodiments, the chamfer 1062 on the last strap pin may face the opposite direction of the chamfer 1062 on the other strap pins. The chamfer 1062 on the last strap pin may prevent the cam spirals 1041 from pulling the strap 56 further into the cam assembly 1030. In some embodiments, the chamfer 1062 on the first strap pin, may keep the strap 56 from being pushed any further out of the cam assembly 1030 and/or the chamfer 1062 on the last strap pin may prevent the strap 56 from being pulled any further into the cam assembly 1030.
In some embodiments, the hard stop 1067 described in greater detail below, may be used as an alternative to the chamfer 1062 and/or in combination with the chamfer 1062. In some embodiments, the hard stop 1067 may be located near the first strap pin and/or last strap pin. In some embodiments, the hard stop 1067 may not include a hole 1066 when used in conjunction with the chamfer 1062 on the last strap pin. In some embodiments, this may prevent the strap 56 from compressing and entering into the cam assembly 1030 regardless of the pressure applied to the strap 56.
As further depicted in
The hard stop 1067 may include a hole 1066 and one or more outward projections 1064. The hole 1066 may allow the outward projections 1064 to compress toward the axial center line of the strap 56 to allow the strap 56 to be inserted into the housing 1044 of the cam assembly 1030. Gently tapered leading edges 1064a allow the strap 56 to enter the housing 1044 with relative ease. More steeply tapered trailing edges 1064b make it more difficult to remove the strap 56 from the housing 1044. In some embodiments, the trailing edge 1064b may catch the strap 56 on the housing 1044 to prevent the strap from falling out of the housing 1044 and may leave the strap 56 in a position to be pulled back in, i.e. in a position such that the first strap pin is in a position to be engaged by the cam spirals 1041 as soon as the knob 1042 is rotated in the tightening direction. In some embodiments, if enough force is used to pull the strap 1048 out of the housing 1044 the outward projections 1064 can temporarily collapse into the hole 1066 and the strap 56 may be removed.
In some embodiments, the guide component pulls the strap 56 away from the cam 1040 so that the strap pins 1048 do not engage on the backside of the cam 1040. In some embodiments, the guide component prevents the system from locking up and/or may strengthen the system by bringing the strap in parallel to the cam 1040 for maximum holding strength. In some embodiments, the load placed on the cam assembly 1030 by the strap 56 may be a shear load, which places a stress parallel or tangential to the cam assembly 1030. The guide component is particularly useful in providing the lowest possible height and/or profile of the housing 1044. The guide component may also allow the strap 56 to be fed into the cam assembly 1030 without catching on the cam 1040.

In one aspect, the headwear 10 includes an adjustment system configured for effecting bearing of the headwear 10 against a surface fraction of the head 14 received within the crown 26 of the headwear 10.
As discussed above, by virtue of the coupling of the actuator 38 to the force transmission member 40, the actuator 38 is configured to effect, when a head 14 is received within the crown 26, and relative to a head 14 received within the crown 26, a change in disposition of the force transmission member 40 to any one of a plurality of conditions in response to an application of force to the actuator 38.
