Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional
Application No. 61/761,091 filed Feb. 5, 2013, incorporated by
reference herein in its entirety.
FIELD OF THE INVENTION
[0002] The present invention generally relates to crocheting.
BACKGROUND OF THE INVENTION
[0003] Crocheting with different types of yarn may present unique
challenges. Existing needles do not work well with open weave
yarns. For example, traditional curved shaft hooks are difficult to
utilize in making scarfs.
SUMMARY OF THE INVENTION
[0004] One embodiment of the invention relates to a straight shaft
latch hook
[0005] Additional features, advantages, and embodiments of the
present disclosure may be set forth from consideration of the
following detailed description, drawings, and claims. Moreover, it
is to be understood that both the foregoing summary of the present
disclosure and the following detailed description are exemplary and
intended to provide further explanation without further limiting
the scope of the present disclosure claimed.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The foregoing and other objects, aspects, features, and
advantages of the disclosure will become more apparent and better
understood by referring to the following description taken in
conjunction with the accompanying drawings, in which:
[0007] FIG. 1 is an illustration of a side view a straight shaft
latch hook.
[0008] FIG. 2 is an illustration of a top view of a straight shaft
latch hook.
[0009] FIG. 3 is an illustration of a side view a straight shaft
latch hook indicating the pin chamber in the shaft.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] In the following detailed description, reference is made to
the accompanying drawings, which form a part hereof. In the
drawings, similar symbols typically identify similar components,
unless context dictates otherwise. The illustrative embodiments
described in the detailed description, drawings, and claims are not
meant to be limiting. Other embodiments may be utilized, and other
changes may be made, without departing from the spirit or scope of
the subject matter presented here. It will be readily understood
that the aspects of the present disclosure, as generally described
herein, and illustrated in the figures, can be arranged,
substituted, combined, and designed in a wide variety of different
configurations, all of which are explicitly contemplated and made
part of this disclosure.
[0011] In one embodiment, a crocheting needle 101 is provided. The
crocheting needle 101 has a shaft 110. The illustrated embodiment
has a substantially straight shaft 110 rather than a bent shaft. In
one embodiment, the shaft 110 is straight, that is linear within
manufacturing tolerances. The straight shaft 110 allows yarn (not
show) to slide on and off the shaft 110 in a smooth transition.
This is particularly useful for techniques using open weave yarn.
For example, open weave yarn can be used with this needle 101 for
making scarfs in a manner different from knitting and crochet.
[0012] One embodiment the needle 101 includes a handle 105. The
shaft 110 extends from the handle 105. In one embodiment, the shaft
110 protrudes from the handle 105 and includes a portion (not
shown) that is embedded in the handle and an exposed portion 111
that extends outside of the handle 105 for engaging the yarn. The
straight shaft 110 includes opposite the handle a hook 120.
Preferably, the hook 120 and/or shaft 110 are made from metal, but
may be made from any suitable material such as, but not limited to
plastic and wood. In one embodiment, the shaft 110 and hook 120 are
one unitary piece. Plastic would not be as strong as metal and
could break easily with extended use. Two areas that would be
vulnerable to breakage are the hook and the point at which the
shaft is attached to the handle.
[0013] In one embodiment, the hook is a curved cylindrical
component. As shown in the Figures, the shaft 110 may also be, in
one embodiment, a cylindrical component. The shaft 110, as
illustrated, has a larger diameter than that of the hook 120. A
tapering portion 130 provides a transition from the larger diameter
shaft 110 to the smaller diameter hook 120. In the illustrated
embodiment, the hook has a radius of curvature of about 0.05 inches
(1.27 mm), preferably about 0.046 inches (1.17 mm). The hook 120
defines a throat 125 of the hook 120. The hook 120 may be in line
with the shaft 110 or may be not in line with the shaft 110, such
as shown in FIGS. 1 and 3. The hook curves from the shaft 110 back
towards the handle 105.
[0014] In one embodiment, a pin 140 is movably attached to the
shaft 110. The pin 140 forms a latch to secure the throat, forming
what is known as a "latch needle". The pin 140 includes a pin shaft
141 having a pin hinge 142. The pin shaft 141 may include a pin
shaft taper portion 143 that has a reduced thickness, such as a
reduced diameter. In one embodiment, the pin shaft 141 is attached
to the shaft 110 via the pin hinge 142 and is rotatable to
effectively close the throat 125 of the hook 120. In the
illustrated embodiment of FIG. 3, a pin chamber 146 is indicated.
The pin chamber 146 is a recessed portion within the shaft 110 into
which all or substantially all of the pin 140 is disposable. As
illustrated in the Figures, best shown in FIG. 2, the pin 140 is in
the same plane as defined by the hook 120 and the shaft 110 to
allow the pin 140 to rotate to engage the hook 120 and, for
embodiments with a pin chamber 146, to be stowed in the pin chamber
146. In one embodiment, the pin 140 is collinear with the shaft 110
when disposed in the pin chamber 146.
[0015] The foregoing description of illustrative embodiments has
been presented for purposes of illustration and of description. It
is not intended to be exhaustive or limiting with respect to the
precise form disclosed, and modifications and variations are
possible in light of the above teachings or may be acquired from
practice of the disclosed embodiments. It is intended that the
scope of the invention be defined by the claims appended hereto and
their equivalents.
