Description
This invention relates to a retaining clip construction. The
invention is particularly concerned with a retaining clip of a type
suitable for positioning a panel of material on a supporting
structure. In the specific example of the invention to be
described, the retaining clips are used in conjunction with
breakfront cabinets. These cabinets comprise doors holding glass
panels, and lattice work panels are often associated with these
doors for decorative purposes.
In securing panels of the type described, and many other
applications, the secured article must be removable for various
reasons. In the case of a breakfront, the glass panel must be
cleaned periodically, and this is a very tedious task with the
lattice work in place. Accordingly, these structures are usually
manufactured so that the lattice work can be removed.
Typical retaining means for the lattice work involve members which
are screwed into place. This requires a rather extensive amount of
work to release the retaining means, particularly if several of
these retaining means are employed for holding a single panel or
other article.
The use of screws for securing retaining means also creates
problems during installation and shipping, and particularly if
glass panels are involved. If the person responsible for applying
the retaining means should make these too tight or too loose, then
breakage of the glass panels can readily occur. Thus, if the
retaining means are too tight, a rather severe jolt may cause
fracture. If the retaining means are too loose, then bouncing of
the glass relative to its support will eventually lead to
fracture.
It is a general object of this invention to provide an improved
retaining means for removably attaching articles such as panels on
a supporting structure.
It is a more specific object of this invention to provide a
retaining means which is particularly useful for securing panels of
glass or other fragile material on cabinet doors or the like
whereby the opportunity for damage during installation, shipping
and other handling is greatly minimized.
It is a still further object of this invention to provide retaining
means of the type described which can be very easily removed and
then reattached. These and other objects of this invention will
appear hereinafter and for purposes of illustration, but not of
limitation, specific embodiments of the invention is shown in the
accompanying drawing in which:
FIG. 1 is a perspective view of a door having a glass panel and a
decorative lattice held in place through the use of the retaining
means of this invention;
FIG. 2 is an enlarged, fragmentary view illustrating the retaining
means of this invention;
FIG. 3 is a fragmentary, cross-sectional view of the retaining
means and associated structure shown in FIG. 2;
FIG. 4 is an exploded perspective view illustrating the components
of the retaining means;
FIG. 5 is a cross-sectional view illustrating an alternative form
of this invention; and,
FIG. 6 is an enlarged cross-sectional view illustrating an
application of the alternative form of the invention.
The construction of this invention generally comprises means for
releasibly attaching an article to a supporting structure. These
means include a retaining clip having a generally V-shaped body
portion with one end of the body portion defining an article
engaging surface; and with the other end of the body portion
defining an elongated opening.
The clip is employed in association with a stud having an enlarged
head positioned on the supporting structure. A ledge is located
adjacent the stud, and a portion of the shank of the stud is
exposed between the head of the stud and the supporting surface.
The elongated opening in the clip includes an enlarged end for
receiving the head of the stud, and the opening then extends to a
slotted section which receives a shank of the stud by sliding the
clip relative to the stud. This sliding movement provides for
engagement of the end of the clip with the adjacent ledge whereby
the clip can be locked in place. Releasing movement of the clip is
accomplished by sliding the clip in the opposite direction. The
clip is formed of spring material, and this composition combined
with the V-shaped configuration provides spring action which serves
to hold the clip in a locked position while permitting the
necessary sliding movement.
FIGS. 1 through 4 illustrate one embodiment of the invention. In
this embodiment, clips 10 are associated with a cabinet door 12.
This cabinet door defines side frame members 14 and upper and lower
frame members 16 and 18. The opening defined between these frame
members removably receives a glass panel 20 and a lattice panel 22.
As best shown in FIG. 3, a flange 24 is defined by the frame
members whereby the panels can be readily located in position.
The clip structure 10 comprises a V-shaped member defining end
portions 26 and 28. The end portion 26 includes a curved section 30
which provides a smooth surface for engagement with the glass panel
20. The other end 28 defines an opening which includes an enlarged
end portion 32 and a slotted portion 34. A dimple 36 is also formed
in this clip portion 28.
The construction of this invention also includes the use of studs,
which in the embodiment shown are associated with the frame members
14. In FIGS. 1 through 4, the studs are formed by means of a wood
screw 38 and washer 40. The washer includes an upwardly extending
cylindrical portion 42 which defines a central opening 44. The
outer diameter of the cylindrical section 42 is less than the
diameter of the head 46 of the screw. The opening 32 in the clip is
sufficiently large to receive the head 46; however, the width of
the slot 34 is less than the diameter of the head 46 but greater
than the diameter of the cylindrical section 42.
In the use of the construction shown in FIGS. 1 through 4, a
plurality of washers 40 are located on the cabinet door 12, the
number of washers depending upon the degree of retaining force
desired for a particular application. The washers are secured in
place by means of the screws 38, and these screws are driven in
until the underside of the heads 46 bear on the upper edges of the
cylindrical sections 42. It will be appreciated that this will
automatically provide precise spacing of the screw heads relative
to the washer and the supporting frame. The bores in the washers 40
also serve as pilot means during insertion of the screws, and
furthermore, this structure provides for locking of the screw.
Thus, the screw head is brought home solidly against the collar 42
and this results in pressure of the screw threads against the wood
which greatly minimizes the chance that the screws will become
loosened.
The provision of the collar or cylindrical portion 42 also provides
an exposed shank for engagement with the clip 10. The clips are
engaged with the studs by first locating the enlarged opening 32 so
that the head 46 passes through this opening. The apex 48 of the
inverted V-shaped clip is then pressed downwardly which
automatically results in sliding of the clip end over the washer
surface with the cylindrical section 42 being received within the
slot 34. The dimpled end 36 eventually snaps over the edge of the
washer to provide a locking action. The dimpled portion preferably
defines a radius corresponding with the washer radius to provide an
over-all grip and smoother operation. As best shown in FIG. 3, the
area 36 is preferably slightly spaced from the surface of the frame
14 to insure a uniform grip and to avoid scratching of the
surface.
It will be appreciated that the clip 10 is manufactured so that a
greater angle would be defined between the end 28 of the clip and
the surface of the frame 14 in the absence of the stud.
Accordingly, the clip surface bears upwardly against the head 46 to
achieve the locking action, this spring action being at least
partially controllable by the cut-out portion 47 defined by the end
portion 26.
The clips 10 can be released by again pressing downwardly on the
apex 48 while exerting rearward pull. Thus, the dimple 36 is drawn
back over the ledge defined by the washer, and this can be
accomplished without difficulty. Once the dimpled end is located on
the washer surface and is moved to bring the opening 32 into the
area of the head 46, the spring pressure will automatically lift
the end portion 28 to completely release the clip.
The releasing movement described is obviously quite simple compared
with a retaining means which requires the loosening of screws.
Thus, the panels 20 and 22 can be quickly taken out of the door
frame for cleaning purposes, and it will be appreciated that the
clip structure is equally satisfactory for retaining articles of
various other types on supporting structures of various designs. As
an alternative to the releasing action described, in some instances
the end 26 can simply be lifted upwardly, and the clip structure
then pivoted around the axis defined by the stud to thereby remove
the clip from engagement with the panel 20. The radius provided in
the dimpled end 36 assists this action.
FIGS. 5 and 6 illustrate a modified form of the invention wherein a
sheet 50 is provided with outwardly extending portions 52. Each of
the portions 52 is provided with a neck 54 defining a central
opening. A rivet 56 is attached in the manner shown whereby the
head of the rivet extends outwardly beyond the neck 54.
As best shown in FIG. 6, the structure described provides a stud
arrangement for a clip 10 substantially corresponding with the
arrangement previously described. The dimple 36 of the clip extends
over the ledge defined by the outwardly formed portion 52 whereby
the previously described locking action is achieved. The neck 54
provides an exposed shank portion, the dimensions of which can be
precisely controlled by the forming operation. Accordingly, the
attachment and removal of the clips 10 can be carried out with the
same efficiency as described with reference to the previous
embodiment.
As shown in FIG. 6, the sheet 50 is provided with a flange 58 for
supporting a panel 60. Alternatively, a plurality of tabs may be
formed in the sheet 50 so that the panel 60 will be supported when
engaged by the clips 10. It will also be appreciated that the panel
60 could merely rest on the surface 62 of the sheet 50. In this
instance, the dimensions and shape of the clip 10 may be varied for
purposes of providing a suitable clamping pressure.
The structures described herein provide significant improvements
when compared with standard clip arrangements. The attachment of
the stud means in the case of washers 40 is very easily
accomplished and does not require any skill or training since the
screw heads 46 will be automatically located in the proper
position, and since the pressure applied by the clips on a glass
pane or the like is not dependent upon the individual involved in
the assembly operations. With regard to the structure shown in
FIGS. 5 and 6, there is also no danger of an assembler creating
conditions which will result in extreme pressure on a glass pane or
the like or which will result in articles which are not retained
with sufficient force.
The arrangement described also provides a safer arrangement while
the clips are holding a glass pane or the like in place. Thus, with
standard arrangements, if a retaining means is secured too firmly,
a jolt can result in cracking of the pane. Similarly, if the
structure is exposed to direct sun, thermal expansion can increase
pressure to the point where fracture will occur. The resilient
character of the structure of this invention will avoid these
problems.
It will be understood that various changes and modifications may be
made in the above described constructions which provide the
characteristics of this invention without departing from the spirit
thereof.
