Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuous-in-part (CIP) application
of Ser. No. 14/500,855, filed on Sep. 29, 2014 now pending, which
is incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to firearms, and more
particularly to a detachable slot cover for a modular hand guard
platform.
BACKGROUND OF THE INVENTION
[0003] In the field of firearms, many of them currently employ
handguards surrounding the barrel and positioned against or
proximate the forward end of a receiver. The handguards typically
provide for protection from dangerous areas of the firearm, as well
as an improved grip and heat dissipation from the barrel of the
firearm while also providing slots and/or rails for mounting
accessories to the weapon. The handguards, despite allowing for
some heat dissipation, may be unable to shield the user from heat
radiating from the firearm. Therefore, there remains a need for a
new and improved design for a protection cover to prevent the user
from heat radiating from the firearm, and the protection cover is
easy to attach to the firearm.
SUMMARY OF THE INVENTION
[0004] It is an object of the present invention to provide a slot
cover to shield the user from heat radiating from a firearm having
a modular hand guard mounting platform.
[0005] It is another object of the present invention to provide a
slot cover that is easy to attach to a firearm with a modular hand
guard mounting platform.
[0006] In one aspect, the present invention provides a slot cover,
which may include a head portion and a bottom portion. The head
portion has a top surface and a bottom surface, and the bottom
portion extends downwardly from the bottom surface. In one
embodiment, the front view of the slot cover is substantially
.pi.-shaped.
[0007] The bottom portion may include a pair of legs, extending
from nearly a center portion of the bottom surface of the head
portion, and a gap is formed between the legs. Each leg has a
concave groove portion right underneath the bottom surface, a first
surface connecting with the groove portion, and a second surface
that is undercut and connecting with the first surface. It is noted
that the first surface extends outwardly from the gap, while the
second surface extends inwardly from the gap.
[0008] In an exemplary embodiment, the slot cover can be used in a
Modular Locking System, M-LOK, which may include a plurality of
slots, and the slot cover is configured to be inserted into each
slot to shield the user from heat radiating from the firearm.
[0009] More specifically, the user can move the legs toward the gap
to insert the slot cover into the slot. Since the legs can be
slightly and elastically deformed, and the second surface is
undercut and extends towards the gap, the second surface can be the
first portion that can be inserted into the slot. The user can
further insert the slot cover into the slot until the first surface
starts to contact the edge of the slot. At this moment, about half
of the bottom portion is in the slot, and the user can release the
hands from the legs and push the slot cover all the way down to the
slot. In one embodiment, the length of the head portion is slightly
greater to the length of the slot, so the slot cover can fully
cover the slot.
[0010] It is noted that when the slot cover is in the slot, each of
the edge of the slot is disposed right at the concave groove
portion to secure the slot cover. Furthermore, since the user
slightly deform the legs when the slot cover is put into the slot,
when the user's hand releases, the legs can be restored to their
original positions, which forms a substantially reverse U-shaped
unit, so it is unlikely to pull the slot cover out of the slot. It
is also noted that a plurality of protrusions are formed on the top
surface of the head portion to provide a better grip for the
user.

DETAILED DESCRIPTION OF THE INVENTION
[0016] The detailed description set forth below is intended as a
description of the presently exemplary device provided in
accordance with aspects of the present invention and is not
intended to represent the only forms in which the present invention
may be prepared or utilized. It is to be understood, rather, that
the same or equivalent functions and components may be accomplished
by different embodiments that are also intended to be encompassed
within the spirit and scope of the invention.
[0017] Unless defined otherwise, all technical and scientific terms
used herein have the same meaning as commonly understood to one of
ordinary skill in the art to which this invention belongs. Although
any methods, devices and materials similar or equivalent to those
described can be used in the practice or testing of the invention,
the exemplary methods, devices and materials are now described.
[0018] All .sub.publications mentioned are incorporated by
reference for the purpose of describing and disclosing, for
example, the designs and methodologies that are described in the
publications that might be used in connection with the presently
described invention. The publications listed or discussed above,
below and throughout the text are provided solely for their
disclosure prior to the filing date of the present application.
Nothing herein is to be construed as an admission that the
inventors are not entitled to antedate such disclosure by virtue of
prior invention.
[0019] In order to further understand the goal, characteristics and
effect of the present invention, a number of embodiments along with
the drawings are illustrated as following:
[0020] In one aspect, referring to FIGS. 1 to 3, the present
invention provides a slot cover 100, which may include a head
portion 110 and a bottom portion 120. The head portion 110 has a
top surface 112 and a bottom surface 114, and the bottom portion
120 extends downwardly from the bottom surface 114. In one
embodiment, as shown in FIG. 1, the front view of the slot cover
100 is substantially .pi.-shaped.
[0021] The bottom portion 120 may include a pair of legs 122,
extending from nearly a center portion of the bottom surface 114 of
the head portion 110, and a gap is formed between the legs 122.
Each leg 122 has a concave groove portion 1221 right underneath the
bottom surface 114, a first surface 1222 connecting with the groove
portion 1221, and a second surface 1223 that is undercut and
connecting with the first surface 1222. It is noted that the first
surface 1222 extends outwardly from the gap 123, while the second
surface extends inwardly from the gap 123, as shown in FIGS. 1 to
3.
[0022] In an exemplary embodiment, the slot cover 100 can be used
in a Modular Locking System, M-LOK, which is a system suitable for
attachments of polymer products. Since polymer products are
durable, cheap, and easy to manufacture, it becomes a good
alternative to non-plastic firearm attachments. As shown in FIGS. 4
and 5, the M-LOK system 200 may include a plurality of slots 220,
and the slot cover 100 is configured to be inserted into each slot
220 to shield the user from heat radiating from the firearm.
[0023] More specifically, the user can move the legs 122 toward the
gap 123 to insert the slot cover 100 into the slot 220. Since the
legs 122 can be slightly and elastically deformed, and the second
surface 1222 is undercut and extends towards the gap 123, the
second surface 1222 can be the first portion that can be inserted
into the slot 220. The user can further insert the slot cover 100
into the slot 220 until the first surface starts to contact the
edge 222 of the slot 220. At this moment, about half of the bottom
portion 120 is in the slot 220, and the user can release the hands
from the legs 122 and push the slot cover 100 all the way down to
the slot 220. In one embodiment, the length of the head portion 110
is slightly greater to the length of the slot 220, so the slot
cover 100 can fully cover the slot 220.
[0024] It is noted that when the slot cover 100 is in the slot 220,
each of the edge 222 of the slot 220 is disposed right at the
concave groove portion 1221 to secure the slot cover 100.
Furthermore, since the user slightly deform the legs 122 when the
slot cover 100 is put into the slot 220, when the user's hand
releases, the legs can be restored to their original positions,
which forms a substantially reverse U-shaped unit, so it is
unlikely to pull the slot cover 100 out of the slot 200. It is also
noted that the a plurality of protrusions 116 are formed on the top
surface 112 of the head portion 110 to provide a better grip for
the user.
[0025] Having described the invention by the description and
illustrations above, it should be understood that these are
exemplary of the invention and are not to be considered as
limiting. Accordingly, the invention is not to be considered as
limited by the foregoing description, but includes any
equivalents.
