Description
The present invention relates to a clip molded of plastic material,
said clip being used, for example, on suspenders or braces for
connecting the suspenders or braces to trousers, or as laundry
clips for fastening laundered underweares and clothing to a clothes
line, and in various other ways.
The object of the present invention is to provide a clip whose
parts can be manufactured extremely easily and economically, and
each of said parts can be assembled very simply and rapidly.
Further object of the present invention is to provide a clip whose
appearance is smart and fine.
In the conventional type clip the assembly thereof was complicated,
whereas a piece of shaft was made to pass through a bore
penetrating through each bearing portion of a pair of bearings
provided in each of clip members and then a spring was mounted on
said shaft. In assemblying this type of clip, the spring was first
spaced in a required portion between upper and lower clip members,
then the bores penetrating through the bearings of said clip
members were arranged in alignment with a passage in the spring for
passing the shaft therethrough. After the shaft was passed through
said bores and passage, both end portions of the shaft projecting
outside of said bores had to be caulked. Thus, much labor and time
were spent for assemblying the conventional type clip which made it
uneconomical. Further, the caulked shaft ends were likely to damage
clothing or the like. Moreover, since both ends of the shaft had to
be caulked outside of the adjacent clip members, it was
uneconomical in the first place because of the additional
processing time and labor, and was also greatly impedimental to a
better appearance of the entire clip.
The inventor has succeeded in obviating the aforesaid disadvantages
and in developing the clip of the present invention which can be
readily and rapidly manufactured and assembled on one hand, and
which is superior in appearance on the other hand. One of the
features of the present invention will be apparent from the
following descriptions.
A clip molded of plastic material comprises at least first and
second clip members formed to open and close freely by means of a
resilient member, for example, a spring member. One of said clip
members has a pair of protruding journals which are integral with
said clip member, while the other clip member has a pair of
bearings each of which is provided with a bearing portion adapted
to receive each of said journals. Each of said journals is fitted
into each of the bearing portions for allowing the pivotal
connection between the first and the second clip members, and when
tension is applied in the longitudinal direction to said clip
members holding any objects, each journal is supported and remain
in each bearing portion without being displaced therefrom.
The clip of the present invention constructed as described above
consists of various members which can be assembled extremely
readily and rapidly as mentioned hereinbefore. Each of the members
can be assembled by fitting the journals of one of the clip members
into the corresponding bearing portions of the bearings of the
other clip member after placing the spring between both clip
members, eliminating the complicated procedure in the conventional
type clip of placing the bores penetrating through the bearings in
alignment with the passage in the spring for passing the shaft
therethrough. Said spring can be mounted between the clip members
quite easily, rapidly and securely by placing one of the extended
portions of the spring into a narrow groove provided in one of the
clip members and other extended portion of the spring into a narrow
groove provided in the other clip member.
When necessary each of the members can be assembled by first
fitting each of the journals of one of the clip members into each
of the corresponding bearing portions of the bearings of the other
clip member and then mounting the spring in the required position
in the inner side of both clip members.
Since the construction of the clip according to the present
invention comprises provision of the protruding journals which are
integral with one of the clip members as mentioned before and which
can be fitted into the bearing portions of the other clip member,
there is no need in the first place to prepare an independent
connecting shaft for connecting both clip members, and in the
second place to caulk the end portions of this type of
journals.

A second (lower) clip member B is a substantially straight plate
and has a pair of opposed bearings 1, 1 projecting vertically
upward from back parts of longitudinal side edges of the plate,
said bearings being molded integrally with the plate. Further
behind said bearings 1, 1 and at the rear end of the plate, there
projects vertically upward from said plate a stopper 2 for
preventing separation of a closing member 3 to be described later
and for blocking further clockwise rotation of the same.
Said closing member 3 has, for example, an extended tail portion
having a connecting slit 5 and a connecting bore 4. Said closing
member 3 is L-shaped when sectional and possesses a bore 7 for
engagement with a rear portion 6 of a first (upper) clip member A
to be described later. Said closing member 3 has a tooth 8
protruding towards said bore 7, and this tooth 8 engages with a
recess 9 in the rear portion 6 of the first clip member A to be
described later when said clip members A and B are in close contact
with each other for holding any objects. On the other hand, a small
projection 10 is projecting from the opposite side of said tooth 8,
and this small projection 10 engages with a recess 11 of the second
clip member B when said clip members A and B are in close contact
with each other for holding any objects.
Said second clip member B may be integrally molded of polystyrene
or other thermoplastic synthetic resins, preferably of hard resins.
In the drawings numeral 12 is a narrow groove for receiving one of
extended portions of a torsion coil spring 13, and numeral 14 is an
auxiliary clip member. This member 14 may be made of natural or
synthetic rubber, or pliable synthetic resins, and the surface
thereof is provided with a number of slots in a direction
transverse to the longitudinal direction of the clip member B for
preventing slip.
Each of said bearings 1 has a bearing portion 15 for supporting
each of journals of the first clip (upper) member A. Each of said
bearing portions 15 comprises a bore 16 and a guiding face 17 for
facilitating engagement of the journal, and the guiding face 17
comprises a substantially oblique section slanting from the inner
side wall of the bearing 1 upwardly towards the outer side wall of
the same, said oblique section being formed at least somewhat close
to said bore 16.
The first clip member A may be integrally molded of polystyrene or
other thermoplastic synthetic resins, preferably of hard resins.
Said first clip member A is a substantially straight plate and has
a pair of opposed journal bases 18, 18 projecting vertically
downward from back parts of longitudinal side edges of the plate,
said journal bases being formed integrally with the plate. From
each of said journal bases 18 there is projecting outwardly a
journal 19 which is integral with the journal base. In the drawings
numeral 20 is a narrow groove for receiving the other extended
portion of the torsion coil spring 13, and numeral 21 is an
auxiliary clip member. This member 21 may be made of natural or
synthetic rubber, or pliable synthetic resins, and the surface
thereof is provided with a number of slots in a direction
transverse to the longitudinal direction of the clip member A for
preventing slip.
Said journals 19 are adapted to fit into the bores 16 of the
bearing portions 15 of the clip member A. Each of the journals 19
has a guiding face 22 for facilitating insertion of the journal at
the top thereof. Said guiding face 22 comprises a substantially
oblique section slanting from the base side of the journal 19
upwardly towards the projected side of the same, said oblique
section of the guiding face 22 being formed to correspond with the
oblique section of the guiding face 17 of the clip member B.
Said recess 11 has a plurality of ridges formed thereon.
FIG. 7 shows a modification wherein an oblique section of a guiding
face 117 of the bearing portion 15 extends up to a bore 116, and an
oblique section of a journal 119 has a form corresponding with the
oblique section of guiding face 117. A bore for the journal 119 in
this modification is a recess 116 as shown in FIG. 7 instead of the
penetrating bore 16.
A modification of the bearing portion 15 of the bearing 1 is shown
in FIG. 8, and in the case of this modification a bearing portion
115 has a slit 117' for guiding the journal and a bore 116' which
communicates with the slit 117'.
Further, as shown in FIG. 9 a journal 119' has no guiding face such
as the guiding face 22. Such journal may also be tapered or only
the top portion thereof may be slightly tapered.
As shown in FIG. 11, one of the bearing portions 15 may be formed
as shown in FIG. 3 and/or FIG. 7 (i.e., the guiding face may or may
not extend up to the bore as shown in FIG. 7 and FIG. 3
respectively, and the bore may be or may not be the penetrating
type as shown in FIG. 3 and FIG. 7 respectively). Also, the journal
19 has such a construction as shown in FIG. 7 (this journal may
alternatively be formed in the shape as shown in FIG. 5). Further,
the other bearing portions 15 may have only the bore 16 and may not
have the guiding face 17 while the journal 19 may be formed without
a guiding face.
The clip according to the present invention is assembled as will
now be described.
First, each of journals 19 of molded clip member A is fitted into a
corresponding bearing portion 15 of a clip member B, particularly
into a bore 16 of the bearing portion 15. However, prior to this
operation, a rear portion 6 of the clip member A is inserted into a
bore 7 of a closing member 3. A torsion coil spring 13 is mounted
between the clip members A and B, particularly between journal
bases 18, 18 of the clip member A simultaneously as the clip
members A and B are joined together by means of a joining device
which is used for joining the members A and B together. One of the
extended portions of the spring 13 is received in a narrow groove
20 of the clip member A, while the other extended portion of the
spring 13 is received in a narrow groove 12 of the clip member
B.
Alternatively, the spring 13 may be pushed into the connecting
portion of the members A and B, particularly between the journal
bases 18, 18 from the free ends of the members A and B after said
members are joined together, and then one of the extended portions
of the spring 13 is placed into the narrow groove 20 and the other
extended portion is placed into the narrow groove 12.
Thus, both members A and B are assembled extremely readily and
rapidly.
Since both clip members can be joined together mainly by fitting
each of the journals 19 into each of the bores 16, there is no need
to arrange bores of both clip members in alignment with a passage
of a spring in order to pass therethrough a shaft as in a
conventional type clip.
Besides, the outer end of the journals need not be caulked at
outside of the bores as was necessary in the conventional type
clip.
Moreover, as each of the journals 19 is integrally formed with the
plastic clip member A, it can be pressed relatively easily into the
bore 16 of each of the bearings 1 which is also integrally molded
of the plastic material with the clip member B. What facilitates
the insertion of the journals 19 into the bores 16 is the provision
of the guiding face 22 on each of the journals 19 and provision of
the corresponding guiding face 17 on each of the bearing portions
15, said guiding face 22 comprising the substantially oblique
section slanting from the base side of the journal upwardly towards
the projected side of the same, while said guiding face 17
comprising the substantially oblique section slanting from the
inner side wall of the bearing 1 upwardly towards the outer side
wall of the same. Both guiding faces 22 and 17 are made to
correspond with each other so that they tend to facilitate smooth
and rapid insertion of the journals 19 into the bores 16.
Both clip members A and B are in open state due to the action of
the torsion coil spring. The closing member 3 is handled resisting
the resilience of said spring, the extended tail portion of the
closing member being brought in contact with the upper end of the
stopper 2 of the clip member B while the small projection 10 is
settled in the recess 11 of the clip member B and the tooth 8 is
settled in the recess 9 of the clip member A, thereby the clip
members A and B are in closed state.
Instead of providing the closing member 3, the clip members A and B
may be opened and closed by using a slider 23 which embraces the
clip members A and B therein as shown in FIG. 10 and slides
horizontally thereon.
The clip as described hereinbefore can be used on suspenders or
braces for connecting the suspenders or braces to trousers. In such
use one end of a pair of suspenders or braces is passed through the
connecting bore 4 by means of the connecting slit 5 and is secured
thereto, while the required end of the trousers is held with the
clipping end of the clip by means of the auxiliary clip members 14
and 21. Said connecting slit 5 may be formed off the center portion
of the bore 4 so that said one end of the pair of suspenders or
braces can not only be easily inserted into the connecting bore 4
but also be prevented from slipping off the bore 4.
This clip can also be used for fastening one end of a band to the
other end of the same by securing one end to the connecting bore 4
of the clip and holding the other end with the clipping ends of the
clip.
The clip according to the present invention can also be used as
laundry clips, paper clips and others as will now be expalined.
The clip shown in FIG. 12 has first and second clip members A' and
B' similar to those shown in FIGS. 1 to 5, FIGS. 7 to 11, FIG. 14
and FIG. 15, and the member B' possesses bearings 1', 1'. However,
the closing member 3 as well as any other parts relative to the
closing member 3 including the stopper 2 are omitted from this
clip. A narrow groove 20' for receiving one of the extended
portions of a spring 13' and a narrow groove 12' for receiving the
other extended portion of the spring 13' are provided respectively
on the extended tail portions of the clip members A' and B'. Said
spring 13' is provided in the reversed direction to the one for the
spring 13 shown in FIG. 1 in order to keep both members A' and B'
usually in closed state.
The auxiliary clip members 21' and 14' shown in FIG. 12 are same as
the members 21 and 14 shown in FIG. 1. Each of the bearings 1' has
a bearing portion 15' for supporting each of journals of the clip
member A'. Each of the bearing portions 15' comprises a bore and a
guiding face for facilitating engagement of the journal, said
guiding face having the same form as the guiding face previously
described, and the modifications of the guiding face previously
described can be applied in this case too. Further, the clip member
A has a pair of journal bases same as previously described, and the
journal protruding outward from each of the journal bases has also
a guiding face same as the one mentioned before.
In a modification shown in FIG. 17, a bearing portion 115 is formed
without having any guiding face but having only a recess for
receiving a journal 119, while the journal 119 is formed having a
guiding face 117.
In a modification shown in FIG. 18, a bearing portion 115 is
provided with a guiding face 117 and a recess for receiving a
journal 119, while no guiding face is formed on the journal
119.
While the embodiments of the invention as shown and described
herein may be taken as preferred examples of the same, it is to be
understood that modifications may be made thereto without departing
from the spirit and scope of the invention as defined by the
following claims.
