Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of U.S. application No.
62/728,375, filed Sep. 7, 2018, and entitled COMPRESSIVE BUMP CAP,
the disclosure of which is incorporated herein by reference in its
entirety.
TECHNICAL FIELD
[0002] The systems and methods described below relate generally to
the field of head protection. More particularly, the systems and
methods relate to compressive bump caps that help protect wearers
from minor cuts, bumps, and bruises due to contact with stationary
objects.
BACKGROUND
[0003] Bump caps are a form of head protection that can be worn in
a number of different environments in which head protection may be
desired, but is not necessarily required. A person in such an
environment may not be required to wear a traditional hardhat, but
still desire to be provided with a certain amount of protection
from lacerations and abrasions caused by minor bumps to the head.
Conventionally, bump caps are not designed to protect against
falling objects, but instead are designed to protect against light
injuries for workers in various settings, such as food industry
workers, mechanics, or trucker drivers, for example.

DETAILED DESCRIPTION
[0012] Various non-limiting embodiments of the present disclosure
will now be described to provide an overall understanding of the
principles of the structure, function, and use of the compressive
bump caps disclosed herein. One or more examples of these
non-limiting embodiments are illustrated in the accompanying
drawings. Those of ordinary skill in the art will understand that
systems and methods specifically described herein and illustrated
in the accompanying drawings are non-limiting embodiments. The
features illustrated or described in connection with one
non-limiting embodiment may be combined with the features of other
non-limiting embodiments. Such modifications and variations are
intended to be included within the scope of the present
disclosure.
[0013] The presently disclosed embodiments are generally directed
to compressive bump caps, compressive bump cap systems, methods of
using a compressive bump cap, and methods of manufacturing
compressive bump caps. Such systems and methods may be implemented
in a wide variety of contexts and applications. In one example
embodiment, the compressive bump cap is configured such that it can
be retained on a user's head without the use of a securing strap,
such as a chinstrap. The compressive bump caps can be constructed
with one or more layers, sections, or pockets of impact absorbing
or impact dissipating materials, referred to generally herein as
padding. The particular type of padding can vary based on a variety
of factors, such as style of compressive bump cap, industrial
application, type of user, size of compressive bump cap, and so
forth.
[0014] As described in more detail below, in some embodiments, the
compressive bump cap can have multiple layers, including an inner
layer, a padding layer, a rigid layer, and an outer layer. Other
embodiments of compressive bump caps can have more than four layers
or less than four layers. The compressive bump cap can also have
breathable characteristics, sweat wicking characteristics, or other
comfort related characteristics, such as vents, mesh, or
perforations. The compressive bump cap can have water resistant or
water repellant qualities. In some embodiments, the compressive
bump cap can include an anti-bacterial agent, anti-microbial agent,
anti-odor agent, or other deodorizing or sanitizing compounds. In
some embodiments, the compressive bump cap is configured to provide
protection against ultraviolet rays using any suitable techniques,
such as chemical treatments, construction techniques, materials,
and so forth.
[0015] As is to be appreciated, the compressive bump cap described
herein can be sized to accommodate different sizes of users. In one
example embodiment, a "one size fits all" compressive bump cap is
sized to most adult wearers. In some embodiments, compressive bump
caps can be manufactured in different sizes (small, medium, large,
x-large, and so forth).
[0016] Reference throughout the specification to "various
embodiments," "some embodiments," "one embodiment," "some example
embodiments," "one example embodiment," or "an embodiment" means
that a particular feature, structure, or characteristic described
in connection with the embodiment is included in at least one
embodiment. Thus, appearances of the phrases "in various
embodiments," "in some embodiments," "in one embodiment," "some
example embodiments," "one example embodiment, or "in an
embodiment" in places throughout the specification are not
necessarily all referring to the same embodiment. Furthermore, the
particular features, structures or characteristics may be combined
in any suitable manner in one or more embodiments.
[0017] Referring now to FIG. 1, a compressive bump cap 100 in
accordance with one non-limiting embodiment is shown. As described
in more detail below, the compressive bump cap 100 can include a
plurality of layers which includes a padding layer and a rigid
layer, sometimes referred to as a shell. Through the use of
stretching fabrics and/or elastics, the compressive bump cap 100
can be configured to be generally compressive such that its
position on a head of a wearer can be maintained without the use of
chin strap. In the illustrated embodiment, the compressive bump cap
100 has an outer layer 102 that is coupled to an elastic member
110. The elastic member 110 can be a band that generally encircles
an opening at a lower periphery of the compressive bump cap 100.
The elastic member 110 can aid in securing the compressive bump cap
100 to a head of a wearer and maintaining its relative placement.
The elastic member 110 may encircle the entire compressive bump cap
100 (as shown) or may be limited to certain portions of the
compressive bump cap, such as the front and/or rear. The elastic
member 110 can comprise, for example, an elastic band or cord
positioned in a hem. As is to be appreciated, the particular
configuration of the compressive bump cap 100 can be based on, for
example, the operational environment of the person wearing the cap.
Some embodiments may include a brim. Some embodiments may include
vents to aid in heat dissipation. Some embodiments may include one
or more thermal layers to aid in heat retention.
[0018] It is noted that while the compressive bump cap 100 depicts
an elastic member around the lower periphery, such elastic members
are not necessary for some configurations. Instead, the compressive
bump cap can have compressive qualities or characteristics that
maintain the compressive bump cap on the wearer's head. In other
words, various layers of the compressive bump cap can be
manufactured from stretchable materials that allow the compressive
bump cap to stretch when placed on the head of a user and contract
when removed from the head of a user. Further as described in more
detail below, the compressive bump cap 100 can include and internal
rigid shell that is positioned to provide head protection for the
wearer.
[0019] Referring now to FIG. 2, a partial cutaway view of an
example compressive bump cap 200 is shown. As shown, a sidewall of
the compressive bump cap 200 is comprised of a plurality of
individual layers. Adjacent layers may or may not be attached to
each other. In the illustrated embodiment, the compressive bump cap
200 has an outer fabric layer 202 and an inner fabric layer 204.
These two layers can be stitched or otherwise coupled together to
define a pocket, or plurality of pockets. Placed between the fabric
layers 202, 204 can be a rigid layer 206 and a padding layer 208.
The rigid layer 206 can be, for example, a pre-formed shell that is
generally hemispherical in shape. In some embodiments, the padding
layer 208 is permanently attached to the rigid layer 206 via
adhesive or other suitable technique. In some embodiments, the
padding layer 208 is removably attached to the rigid layer 206 via
hook and loop fasteners or other suitable techniques. In some
embodiments, the padding layer 208 and the rigid layer 206 can
collectively form an inner protection system of the compressive
bump cap 200.
[0020] The padding layer 208 and the rigid layer 206 can be
disconnected from both of the fabric layers 202, 204, such that the
inner protection system is positioned within the pocket defined by
the fabric layers 202, 204, but is generally free-floating
therebetween. In other embodiments, however, one or both of the
fabric layers 202, 204 are coupled to rigid layer 206, the padding
layer 208, or both the rigid layer 206 and the padding layer 208.
Similar to FIG. 1, the compressive bump cap 200 can also have an
elastic member 210 that encircles the head-sized opening. As shown
each of the fabric layers 202, 204 can be coupled to the elastic
member 210, such as through stitching.
[0021] When the compressive bump cap 200 is placed on the head of a
wearer, various components can stretch to generally conform to the
shape of the wearer's head. Accordingly, the compressive bump cap
200 can stretch to a convex-shaped configuration, which may be
referred to as hemispherical, when being worn by a user. In its
stretched configuration, the compressive bump cap 200 delivers a
compressive force to the wearer's head in order to substantially
maintain the position of the compressive bump cap 200 relative to
the wearer's head. It is noted that certain components of the
compressive bump cap 200 can be mesh, or at least comprise one or
more portions that are mesh or otherwise provide air flow to the
wear.
[0022] Referring now to FIGS. 3A-3C, a compressive bump cap 300 in
accordance with one non-limiting embodiment is shown. FIG. 3A shows
a side view of the compressive bump cap 300 which has an elastic
member 310 positioned around its lower periphery. The elastic
member 310 can be an elastic band positioned inside a hem, for
example. In some embodiments, an elastic member can be fed through
hoops or other retention members. FIG. 3B shows a cross-sectional
view of the compressive bump cap 300 taken along line 3B-3B of FIG.
3A. FIG. 3C shows an enlarged view of the encircled area of FIG. 3B
and illustrates various layers of the compressive bump cap 300. As
shown in FIGS. 3A-3C the compressive bump cap 300 of the
illustrated embodiment comprises an outer layer 302, a rigid layer
306, a padding layer 308, and an inner layer 304. A layer of
adhesive may be applied between the rigid layer 306 and the padding
layer 308.
[0023] The padding layer utilized by compressive bump caps in
accordance with the present disclosure can be comprised of any
suitable material that provides the desirable characteristics and
response to impact. For example, the padding layer can comprise one
or more of the following materials: thermoplastic polyurethane
(available, for example, from Skydex Technologies), military-grade
materials, impact absorbing silicone, D30.RTM. impact absorbing
material, impact gel, wovens, non-wovens, cotton, elastomers,
IMPAXX.RTM. energy-absorbing foam (available from Dow Automotive),
DEFLEXION shock absorbing material (available from Dow Corning),
styrofoam, polymer gels, general shock absorbing elastometers,
visco-elastic polymers, PORON.RTM. XRD impact protection (available
from Rogers Corporation), Sorbothane.RTM. (available from
Sorbothane Inc.), Neoprene (available from DuPont), Ethyl Vinyl
Acetate, impact-dispersing gels, foams, rubbers, and so forth. The
padding layer can be breathable and/or generally porous to provide
ventilation. In some embodiments, the padding layer is a mesh
material that aids in the breathability of the associated
compressive bump cap. The padding layer can be attached to one or
more layers (such as the rigid layer 306 and the inner layer 304 of
FIG. 3C, for example). In some embodiments, the padding layer can
be generally disconnected and "floating" between the layers. In
some embodiments, the padding layer is attached to an elastic
member or other portions of the compressive bump cap.
[0024] In some embodiments, padding layers in accordance with the
present systems and methods can comprise a rate dependent material,
such as a rate dependent low density foam material. Examples of
suitable low density foams include polyester and polyether
polyurethane foams. In some embodiments, such foams to have a
density ranging from about 5 to about 35 pounds per cubic foot
(pcf), more particularly from about 10 to about 30 pcf, and more
particularly still from about 15 to about 25 pcf. PORON.RTM. and
PORON XRD.RTM. are available from Rogers Corporation, which are
open cell, microcellular polyurethane foams, is an example of one
suitable rate dependent foam. However, in order to provide impact
resistance, the padding layer can be any suitable energy absorbing
or rate dependent materials. As such, other rate dependent foams or
other types of materials can be used without departing from the
scope of the present disclosure.
[0025] The material can be, for example, and without limitation,
polyester, nylon, spandex, ELASTENE (available from Dow Chemical),
cotton, materials that glow in the dark or are fluorescent, and so
forth. Either of the inner or outer layers can also be of a mesh or
otherwise porous material. In some embodiments, the inner and/or
outer layers can be a blend of a variety of materials, such as a
spandex/polyester blend. In some embodiments, the compressive bump
cap is water proof, water resistant, or water repellant. Other
durable materials can be used for the outer layer of any
embodiment, including knit, woven and nonwoven fabrics, leather,
vinyl or any other suitable material. In some instances, it can be
desirable to use materials for the layer than are somewhat elastic;
therefore, stretchable fabrics, such as spandex fabrics, can be
desirable. Such materials can help provide compressive forces to
maintain placement of compressive bump cap on a wearer's head
without the need for a chin strap, for example.
[0026] The rigid layer utilized by compressive bump caps in
accordance with the present disclosure can be comprised of any
suitable material that provides the desirable characteristics and
response to impact. The rigid layer can be, for example, a molded
plastic, Styrofoam, thermoplastic, carbon fiber, or other suitable
rigid or semi-rigid materials.
[0027] Various compressive bump caps in accordance with the systems
and methods described herein can be manufactured with or otherwise
include various coatings, agents, or treatments to provide
anti-microbial or anti-bacterial properties. Some embodiments, for
example, can utilize Microban.RTM. offered by Microban
International, Ltd. for antibacterial protection. In some
embodiments, the padding layer comprises antimicrobial agents and
one or more other fabric layers of the compressive bump cap also
treated with antimicrobial agents. Antimicrobial protection for the
fabric layers can be in the form of a chemical coating applied to
the fabric, for example. Generally, antimicrobial technologies
combat odor by fighting bacteria resulting in fresher smell for
longer and minimizing the frequency of laundering or washing. Any
suitable technique can be used to provide compressive bump caps
with antimicrobial properties. In one embodiment, for example,
AEGIS Microbe Shield.RTM. offered by DOW Corning Corp. is utilized.
Other examples of antimicrobial agents include SILVADUR.RTM.
offered by The Dow Chemical Company is utilized, Smart Silver
offered by NanoHorizons, Inc., and HealthGuard.RTM. Premium
Protection offered by HealthGuard.
[0028] In some embodiments, a compressive bump cap, or at least
various components of a compressive bump cap are configured to
provide moisture wicking properties. Generally, moisture wicking
translates into sweat management, which works by removing
perspiration from the skin in an attempt to cool the wearer. Any
suitable moisture wicking can be used. In one embodiment, a topical
application of a moisture wicking treatment to a fabric of the
compressive bump cap is utilized. The topical treatment is applied
to give the compressive bump cap the ability to absorb sweat. The
hydrophilic (water-absorbing) finish or treatment generally allows
the compressive bump cap to absorb residue, while the hydrophobic
(water-repellent) fibers of the compressive bump cap help it to dry
fast, keeping the wearer more comfortable. In one embodiment, the
blend of fiber is used to deliver moisture wicking properties by
combining a blend of both hydrophobic (such as polyester) with
hydrophilic fibers. Certain blends of these fibers allow the
hydrophilic fibers to absorb fluid, moving it over a large surface
area, while the hydrophobic fibers speed drying time. One benefit
of compressive bump caps utilizing these types of fiber blends is
that moisture management properties are inherent in the fiber
blend, meaning they will never wash or wear out.
[0029] FIG. 4 depicts the compressive bump cap 300 shown in FIGS.
3A-3C stretching from a relaxed configuration shown by the
compressive bump cap 300A to an expanded configuration, which is
shown by the compressive bump cap 300C. As compressive bump cap
300A is placed on the head of a wearer, the stretchable components
of the multi-layered sidewall begins to expand, as shown by
compressive bump cap 300B. As the head of the wearer is inserted
further into the compressive bump cap, the compressive bump cap
continues to stretch until it reaches an expanded configuration,
shown by compressive bump cap 300C. As is to be appreciated, due to
the stretchability of the compressive bump cap 300, it can
accommodate a range of head sizes and shapes.
[0030] FIG. 5 is an exploded view of a compressive bump cap 400 in
accordance with one non-limiting embodiment. The illustrated
compressive bump cap 400 has an outer layer 402. The outer layer
402 can be formed of a single panel or a collection of panels that
are attached to form a dome-like structure. A rigid layer 406 can
be positioned beneath the outer layer 402. In some embodiments, the
rigid layer 406 is an injection molded plastic shell, although this
disclosure is not so limited.
[0031] Beneath the rigid layer 406 is a padding layer 408. The
padding layer 408 can be generally pliable or flexible. FIG. 7
depicts one example of a padding layer 600 in a flat, unattached
state. The padding layer 600 can be cut or formed such that it can
be manipulated to be received into the dome-like structure of a
rigid layer. Referring again to FIG. 5, an inner layer 404 can be
positioned beneath the padding layer 408. An elastic member 410 can
be attached to the lower periphery of the compressive bump cap
400.
[0032] FIG. 6 is an exploded view of another example compressive
bump cap 500 in accordance with one non-limiting embodiment.
Similar to FIG. 5, the compressive bump cap 500 has an outer layer
502 and an inner layer 504, each of which may be flexible and
stretchable to help provide compressive qualities. A elastic member
510 may also be utilized to help secure the compressive bump cap
500 to the head of wearer. FIG. 6 depicts that the compressive bump
cap 500 can use any of a number of different styles for the rigid
layer 506 and the padding layer 508. Non-limiting examples of the
rigid layer 506 are depicted by rigid layers 506A-C. Non-limiting
examples of the padding layer 508 are depicted by padding layers
508A-C. For example, the padding layer 508 can be a collection of
individual modules or pods that are attached to the rigid layer
506. The inner layer 504 and the outer layer 502 can be
manufactured from a stretchable material. In some embodiments, the
surface area of the padding layer 508 and the rigid layer 506 are
slightly smaller than the surface area of the outer layer 502.
Furthermore, the padding layer 508 can also be stretchable, though
not necessarily as stretchable as the inner layer 5040 and the
outer layer 502. The inner layer 504 and the outer layer 502 can
cooperate to define a pocket, with the padding layer 508 and the
rigid layer 506 removably or non-removably positioned in the
pocket.
[0033] Compressive bump caps in accordance with the presently
disclosed embodiments may be manufactured using a variety of
manufacturing techniques, such as ultrasonic welding, stitching,
gluing, and/or quilting, for example. Stitching can be used to
couple an interior fabric layer to an external fabric layer to
create a pocket to house the padding layer and the rigid layer. In
some embodiments, double needle stitching is utilized to attach
various components of the compressive bump cap. With a double
stitching technique, twin needles create parallel double stitching
using two needles mounted in a plastic holder. A standard needle
shank is added to the plastic holder so it can be to inserted in
the needle holder on the sewing machine. One needle can be shorter
than the other so that a bobbin can catch both stitches. The
compressive bump caps can be manufactured in different sizes so
that they can accommodate both children head sizes and adult head
sizes.
[0034] The particular combination of materials for the various
layers of compressive bump caps manufactured in accordance with the
systems and methods described herein can vary. Below are some
non-limiting examples of material combinations. As is to be readily
appreciated, other combinations are envisioned and are within the
scope of the present disclosure. For some compressive bump caps,
one or more layers can comprise about 80-90% polyester or Nylon and
about 10-20% Spandex or Elastene. In one embodiment, one or more
layers can comprise about 86% polyester and about 14% Spandex. One
or more layers can also be a mesh-type material for increased
breathability and ventilation. The layers of the compressive bump
cap can have various fabric weights. In some embodiments, the
fabric weight of an outer or inner lay can be in the range of about
5 to about 12 ounces, for example.
[0035] In some embodiments, one or more of the fabric layers can
comprise about 60% polyester and about 40% cotton. In one
embodiment, one or more fabric layers can comprise about 100%
cotton. In one embodiment, one or more fabric layers can comprise
about 80% polyester and about 20% spandex. In one embodiment, one
or more fabric layers can comprise about 90% polyester and about
10% Spandex. In one embodiment, one or more fabric layers can
comprise about 86% polyester and about 14% Spandex. In some
