Abstract

A protective cap including an outer shell and an impact absorbing liner are constructed of materials designed to provide impact protection to a wearer. In some embodiments, the outer shell includes an outer surface pattern and/or an inner surface pattern to provide better grip and reduce rotation between the outer shell and the impact absorbing liner and/or the outer shell and a hat the user wears to cover the protective cap.

Claims (57)

1 . A protective cap comprising:

an outer shell, the outer shell comprising:

an exterior surface, the exterior surface comprising:

a patterned portion, the patterned portion configured to engage an inner surface of headwear covering the protective cap, the patterned portion comprising:

a plurality of protruding structures each extending away from the exterior surface; and

a plurality of sunken central sections, each recessed relative to one of the plurality of protruding structures, wherein each of the sunken central sections is completely surrounded by one of the plurality of protruding structures;

an interior surface defining a cavity sized to receive a head of a user;

a crown portion, the crown portion configured to cover part of the head of the user; and

a bottom segment, the bottom segment defining a lower circumference of the outer shell;

an impact absorbing liner positioned within the outer shell and engaged with the interior surface of the outer shell-

a front portion;

a rear portion;

a pair of side portions extending downward from the crown portion and positioned between the front portion and the rear portion, each of the pair of side portions comprising:

a side recessed portion;

a plurality of side vents:

wherein the side recessed portion is positioned above the plurality of side vents; wherein the plurality of side vents is positioned below the side recessed portion and above the bottom segment.

2 . The protective cap of claim 1 , wherein the patterned portion extends along the crown portion between the front portion and the rear portion of the outer shell.

3 . The protective cap of claim 1 , wherein each of the protruding structures of the patterned portion is a hexagonal shaped structure.

4 . The protective cap of claim 1 , further comprising one or more vents positioned on the plurality of sunken central sections, the vents extending through the outer shell between the interior surface and the exterior surface to provide fluid communication between the cavity and ambient air proximate to the exterior surface of the outer shell.

5 . The protective cap of claim 1 , further comprising ramps coupled to the outer shell and extending upward from the exterior surface of the outer shell toward the patterned portion.

6 . The protective cap of claim 1 , wherein, when the patterned portion engages an inner surface of the headwear, the patterned portion resists relative rotation between the headwear and the outer shell.

7 . The protective cap of claim 1 , further comprising one or more slots defined in the outer shell, the slots extending from the bottom segment toward the crown portion.

8 . The protective cap of claim 7 , wherein the one or more slots are vertical slots positioned on the front portion or the rear portion of the outer shell.

9 . A bump cap comprising:

an outer shell, the outer shell comprising:

an exterior surface, the exterior surface comprising:

a patterned portion, the patterned portion comprising:

a plurality of protruding structures each extending away from the exterior surface; and

a plurality of sunken central sections, each recessed relative to one of the plurality of the protruding structures, wherein each of the sunken central sections is completely surrounded by one of the plurality of protruding structures;

an interior surface defining a cavity sized to receive a head of a user;

a crown portion, the crown portion configured to cover part of the head of the user;

a bottom segment, the bottom segment defining a lower circumference of the outer shell;

a front portion;

a rear portion that opposes the front portion;

a pair of side portions extending downward from the crown portion and positioned between the front portion and the rear portion; and

a trimmable section extending along the bottom segment of each of the pair of side portions, the trimmable section comprising a shoulder extending along a longitudinal axis of the bump cap, wherein the shoulder provides a transition between a thick section of the outer shell and a thin section of the outer shell; and

an impact absorbing liner positioned within the outer shell and coupled to the interior surface of the outer shell.

10 . The bump cap of claim 9 , wherein the thick section has a first thickness and the thin section has a second thickness, and wherein the first thickness is greater than the second thickness.

11 . The bump cap of claim 9 , wherein the shoulder is a stepped transition between the thick section of the outer shell and the thin section of the outer shell.

12 . The bump cap of claim 9 , the each of the pair of side portions comprising:

a side recessed portion located along the side portion; and

a plurality of side vents;

wherein the side recessed portion is positioned above the plurality of side vents; and wherein the plurality of side vents is positioned below the side recessed portion and above the bottom segment.

13 . The bump cap of claim 9 , further comprising one or more vertical slots defined in the outer shell, the vertical slots positioned on at least one of the front portion and the rear portion, wherein the vertical slots extend from the bottom segment toward the crown portion.

14 . The bump cap of claim 9 , wherein the outer shell is formed from a rigid polymer material and the impact absorbing liner is formed from a polymer foam material.

15 . A bump cap comprising:

an outer shell, the outer shell comprising:

a crown portion, the crown portion configured to cover part of a head of a user;

a bottom segment, the bottom segment defining a lower circumference of the outer shell;

an exterior surface;

a plurality of protruding structures each extending away from the exterior surface; and

a plurality of sunken sections, each sunken section positioned within one of the plurality of protruding structures and recessed relative to the protruding structure, wherein each of the sunken sections is completely surrounded by one of the plurality of protruding structures;

an interior surface defining a cavity sized to receive the head of the user; and

an impact absorbing liner positioned within the outer shell and engaged with the interior surface of the outer shell; and

a trimmable section extending along the bottom segment of the outer shell, wherein the trimmable section comprises a step, and wherein the step provides a transition between a thick portion of the outer shell and a thin portion of the outer shell.

16 . The bump cap of claim 15 , wherein each of the plurality of sunken sections has a polygonal shape.

17 . The bump cap of claim 15 , further comprising one or more slots defined in the outer shell, the slots extending from the bottom segment toward the crown portion.
