Description
FIELD OF THE INVENTION
[0001] Current application relates to work pants, especially to a
work pants equipped with detachable knee protection pads.
BACKGROUND OF THE INVENTION
[0002] Lots of knee protections are introduced to the market.
However, they can be classified as two big groups. One group is
wearing directly on knee and the other group is attached on a
pants. Most of sporting knee protectors belongs to the first group.
People wear those knee protectors when play volley ball, roller
blade, rock climbing cycling, etc. Those direct wearing knee
protectors are fastened by ties or made of elastic materials to
fasten them to knees of a wearer. Some of them are worn on a
sporting pants and work pants. However, if the knee pads are too
much tightened, they block circulation of blood in the leg of
wearer. Those kinds of knee protectors are not wearable for a
worker who should kneel down for hours. Almost all of knee
protectors on a work pants are stitched to the pants. It is
impossible to wash knee protectors separately from the work pants.
Some other knee protectors are inserted in pockets that are
stitched to a work pants. For those pocket type knee protectors,
the pad itself can be washed separately. However, if foreign
objects are inserted, the wearer must open the pocket and take out
the pads and the foreign objects. It is purpose of the current
application to provide working pants that is easy to clean the
pants and the pads separately.

SUMMARY OF THE INVENTION
[0007] Lots of knee protections are introduced to the market.
However, they can be classified as two big groups. One group is
wearing directly on knee and the other group is attached on a
pants. Most of sporting knee protectors belongs to the first group.
People wear those knee protectors when they play volley ball,
roller blade, rock climbing cycling, etc. Those direct wearing knee
protectors are fastened by ties or made of elastic materials to
fasten them to knees of a wearer. Some of them are worn on a
sporting pants and work pants. However, if the knee pads are too
much fastened, they block circulation of blood in the leg of
wearer. Those kinds of knee protectors are not wearable for a
worker who should kneel down for hours. Most of knee protectors on
a work pants are stitched to the pants. It is impossible to wash
knee protectors separately from the work pants. Some other knee
protectors are inserted in pockets that are stitched to a work
pants. For those pocket type knee protectors, the pad itself can be
washed separately. However, if a foreign object is inserted, the
wearer must open the pocket and take out the pads and the foreign
objects. It is purpose of the current application to provide a
working pants that is easy to clean the pants and the pads
separately. A work pants equipped with knee protection pads is
provided. Four male button clips are placed on each leg member of
the pants surrounding knee contacting portion of the work pants to
avoid contact with knees when a wearer of the work pant kneel down.
The knee protection pads for the work pants according to current
application are equipped with four female button clips that receive
the four male button clips. The knee protection pads are easy to
detach from the work pants to wash the pants and pads separately.
Objects such as wood chips, soil, nails, etc., get inserted between
the pants and pads are easily removed by detaching the pad and
seeping them out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] FIG. 1 is a perspective front view of a work pants (1)
equipped with two detachable knee protection pads (2) according to
current application. Each kneel protection pad (2) is attached to
the pants (1) on the knee portion (3). FIG. 2 is an enlarged
perspective exploded view of a work pants (1) equipped with two
detachable knee protection pads (2) showing engagement of male clip
button (4-M) and female clip button (4-F). FIG. 3 is a side view of
the work pants (1) equipped with two detachable knee protection
pads (2) according to current application. Eight male clip buttons
(4-M) which are placed on the knee portion of the pants on seam
lines (8). Among them, two male clip button buttons (4-M) are
placed on outer seam line (8-L-O) of left leg of the pants. Another
two male clip button buttons (4-M) are placed on inner seam line
(8-L-I) of left leg of the pants. The other two male clip button
buttons (4-M) are placed on inner seam line (8-R-I) of right leg of
the pants and last two male clip buttons (4-M) are place on outer
seam line (8-R-O) of right leg of the pants. The knee protection
pads (2) are in a shape of shield. The pad (2) is comprised of a
cushion material (5), such as sponge, covered with cloths (6). The
protection pad (2) is stitched along the brim (7), except the top,
thereof to hold the cushion material (5) therein. Four female clip
buttons (4-F) are placed on the stitched brim (7) to receive the
male clip buttons (4-M) that match in position. Most of work pants
of prior arts, equipped with knee protection pads, are not
separable from the pads. So, it is not an easy job to wash the
pants with pad. However, as shown in FIGS. 1 to 3, the pads (2)
according to current application are easily detachable from the
pants (1). Therefore, user of the pants (1) can wash the pants (I)
and pads (2) separately. It is the first benefit of the current
application over the prior arts. FIG. 4 is a cross-sectional view
along the line A-A' seen from view point A'' in FIG. 1. Due to the
structure of the pad (2), a gap (9) is developed between the pad
(2) and the pants (1) when a user of the pants (1) stands up. Then
foreign objects (10), which may be entrapped into the gap (9), can
be easily removed by just stand up and shake them off. It is the
second benefit of the current application.
[0013] Among the prior arts, U.S. Pat. No. 2,561,872 to J. Krinick
is closest to current application. Krinick used snap fastener, kind
of clip button, to attach sponge like pad to a work pants. However,
the snap fasteners are located in front of the knee portion of the
pants. Then, the snap fasteners will press knee of the wearer when
the wearer kneels down on the ground. It is clear that so much pain
will burdens the wearer when some metallic parts are laid under the
knee of a person and pressed by the weight of a user.
[0014] To avoid such pain clip buttons (4) are placed closed to
seam line (8) in the current application.
[0015] Another closest prior art is U.S. Pat. No. 5,732,412 to
Holden. He discloses an attaching facility 32, as shown in FIGS. 13
and 13a and from column 5 lines 28 to line 39. The facility 32 is a
slap-on style type 44, which consists of a first pair of VELCRO
strips 46. A substance 48 is for securing each first VELCRO strip
46 vertically along an inner surface of one tapered side 28 of the
flexible semi-cylindrical body section 24 of the cushion member 22.
Second pair of VELCRO strips 50 is provided. A substance 52 is for
securing each second VELCRO strip 50 vertically along an outer
surface of the pant leg 34 at the knee area; so that the first pair
of VELCRO strips 46 can mate with the second pair of VELCRO strips
50. Holden used pair of VELCRO.RTM., indicated as 46 and 50, and
additional substance 52 to secure the VELCRO.RTM. S. It needs more
steps than the current application to make the product. In addition
to this, dirt and threads from clothes are easily stick to the
VELCRO.RTM. when do laundry. They should be removed to maintain the
sticking force of the VELCRO.RTM.. It needs another effort to
maintain the pads attachable to a work pants.
[0016] As a conclusion, the work pants equipped with detachable
knee protection pads according to current application is most
simple and easy to clean one ever introduced.
