Background of the invention
[0001] Button covers are known from a number of documents in the art. Such button covers
comprise a covering member having an ornamental face for covering the face of the
button. Often, a holding member is connected in an articulated manner to the covering
member, the holding member being designed for taking up the threads with which the
button is sewn to the garment. Such a button cover is disclosed, e.g., in
U.S. Patent No. 3,777,336. Such button covers are relatively complex in their manufacture, and the articulation
may break in the course of frequent use. In addition, such button covers often do
not have an entirely satisfactory aesthetic appearance due to the presence of visible
mechanical features such as slits.
[0002] U.S. Patent No. 5'033,168 discloses a button cover whose covering member has an ornamental
face, a circular edge extending away from the face, and a semiannular projection inwardly
extending from said edge. An annular holding member is coaxially connected to the
edge for sliding in a circumferential direction, the holding member having a second
semiannular projection. By sliding the holding member relative to the covering member
in the circumferential direction, the button cover may be brought from an open configuration
for inserting a button into a closed configuration in which the button is locked within
the cover. Handling of such a button cover when fixing the button cover to a button
on a garment can be difficult.
Summary of the invention
[0003] It is therefore an object of the present invention to provide a button cover which
can be manufactured economically, which is aesthetically pleasing and which may be
fastened to a button sewn onto a piece of garment without difficulty.
[0004] This object is achieved by a button cover according to claim 1.
[0005] In particular, a button cover according to the present invention comprises a button
covering member having a cover portion with an ornamental outer face and an inner
face opposite to (i.e., on the other side than) the ornamental outer face. The button
cover further comprises a plurality of elastic protrusions (preferably at least three)
extending inwardly from a perimeter region of said button cover. These elastic protrusions
are elastically deformable towards and away from the inner face of the cover portion.
In particular, they are disposed in a region adjacent to the inner face. Such a button
cover may be easily mounted on a button by simply pushing the button cover onto the
button, while the elastic protrusions will first give way for the button and then,
after the protrusions have been moved past the button, hold the button cover in place
while the button is disposed in the space between the protrusions and the inner face.
[0006] In an advantageous embodiment, the protrusions have the shape of bristles, i.e.,
an elongated, essentially cylindrical shape with a diameter which is much smaller
than the length. Such a button cover is easily manufactured. Even if a few of the
bristles break, several other bristles will still be present to hold the button. Requirements
on tenacity and elastic properties of the material used will be relatively low because
the force acting on a single bristle will be relatively small. The protrusions may
alternatively have other shapes, such as the shape of thin, elastic leaves or vanes.
[0007] The button cover may be manufactured in one piece. Advantageously, however, the button
cover comprises a separate holding member which is connected or connectable to the
button covering member. The holding member comprises the elastic protrusions and support
means for these protrusions which are arranged in a perimeter region of the holding
member. The elastic protrusions extend inwardly from these support means. Preferably,
the holding member is releasably connectable to the button covering member, enabling
a simple mounting of the button cover by first pushing only the holding element over
the button and only then mounting the covering member on the holding member.
[0008] Preferably, the elastic protrusions are formed in one piece with a carrier element.
The carrier element is then preferably attached to a reinforcement element for increasing
the stability of the holding member. The above-mentioned support means thus comprise
both the carrier element and the reinforcement element. In an advantageous embodiment,
the carrier element is essentially ring-shaped, and the reinforcement element radially
surrounds the carrier element, i.e., it is disposed around the perimeter of the carrier
element. In particular, it may be essentially ring-shaped. The reinforcement element
may be connected to the carrier element, e.g., by being clamped by flanges extending
inwardly from the perimeter of the reinforcement element on both sides of the carrier
element, or by gluing.
[0009] The connection between the button covering member and the holding member may be simply
established by a press fit. To this end, the button covering member may comprise at
least one sidewall portion extending preferably at a right angle from the cover portion
and defining an inner sidewall, and the holding member may have an outer shape essentially
corresponding to the shape delimited by this inner sidewall of the button covering
member. The holding member may then be removably fastened to the button covering member
by pressing the holding member into the region delimited by the inner sidewall of
the button covering member. In addition or instead, the inner sidewall may have engagement
means such as noses for a releasable snap-in connection with the holding member.
[0010] In an advantageous embodiment, the protrusions are arranged in a plurality of rows
on the support means. This is especially preferable if the protrusions have the shape
of bristles. Preferably, the protrusions extend in a direction essentially parallel
to the inner face of the cover portion when they are in their relaxed, normal state,
thereby defining a hollow space in the button cover for taking up the button.
[0011] The invention further relates to an adapter for use with a button cover according
to the present invention, which serves to extend the range of possible uses of the
button cover and transforms the button cover into a multifunctional jewelry item.
The adapter comprises an insert section adapted in shape and size for being received
within the button cover, in particular between the inner face of the cover portion
and the elastic protrusions of the button cover. The insert section may be button-shaped.
Connection means are provided which are adapted for releasably connecting the adapter
to a garment, to a body part or to a jewelry item. In particular, the connection means
may comprise a pin (preferably a safety pin), an ear pin, an ear clip, or a hanger
for a necklace. The connection means may also comprise a second insert section for
being inserted into a second button cover, for forming a cuff link. In an advantageous
embodiment, the connection means are connected to the insert section via a stem section
adapted for passing through a region left free by the elastic protrusions of the button
cover.

Detailed description of the invention
[0013] Figs. 1 to 4 show different views of a button cover 1 according to a first embodiment
of the present invention. In particular, Fig. 2 shows a detail view of the region
marked "A" in Fig. 1. The button cover 1 comprises two main members, a covering member
10 and a holding member 20. The covering member 10 has the shape of a hollow cap,
i.e., it comprises a flat cover portion 12 and a circumferential, cylindrical sidewall
portion 11 extending away from the inner face 12a of the flat cover portion 12 at
essentially a right angle. The length of the sidewall portion 11 is larger than the
thickness of the button. In particular, this length is larger than the sum of the
thickness of the button and the thickness of the holding member 20 described below.
The cover portion 12 further has an ornamental outer face 12b which may be faceted
or may carry precious stones or other ornaments in order to give it a pleasing appearance.
The covering member 10 may be manufactured from any sufficiently rigid and tenacious
material, such as a plastics material or a metal or metal alloy such as stainless
steel, bronze, brass, silver or gold. If made from a plastics material, it may advantageously
be manufactured by injection molding.
[0014] The holding member 20 comprises a circular, ring-shaped carrier 21, a large number
of bristles 22 extending inwardly from the carrier 21, and a reinforcement element
24. The bristles 22 are arranged on the carrier 21 in a plurality of parallel rows,
in this particular example four rows, each row extending along the circumferential
direction of the carrier 21. The free ends of the bristles 22 define a central circular
opening 23. The bristles 22 are elastically deformable, in particular, bendable inwardly
and outwardly away from the plane defined by the support 21. They are preferably manufactured
from a tenacious, yet elastic material such as silicone rubber or other elastic synthetic
materials. The bristles are formed in one piece with the ring-shaped carrier 21 made
from the same material. This one-piece combination of a ring-shaped carrier and bristles
may be called a "brush ring". The brush ring in itself is relatively flexible and
is thus not sufficiently rigid to be used as a holding member as it is. Therefore,
in order to improve stability of the holding member, the carrier 21 is surrounded
by the ring-shaped reinforcement element 24 radially surrounding the carrier 21 and
having inwardly extending flanges 25 on both sides of the carrier 21 for securing
the carrier 21 to the reinforcement element 24. In other words, the reinforcement
element 24 has the shape of a hollow ring which is inwardly open, similar in shape
to a car tire, where the hollow inner region partially takes up the carrier 21. The
reinforcement element 24 is manufactured from a more rigid material than the brush
ring, e.g., from the same material as the covering member, in particular, a plastics
material or a (sheet) metal or metal alloy. The carrier 21 is held in the reinforcement
element 24, e.g., by clamping or by gluing. Together, the carrier 21 and the reinforcement
element 24 may be regarded as serving as the support means for the bristles 22.
[0015] For mounting the button cover 1 on a button sewn to a garment by a thread, the holding
member 20 is pushed over the button such that the central opening 23 encloses the
thread. In order for the holding member to be held on the button, the diameter of
the central opening 23 should be smaller than the diameter of the button. When pushing
the holding member over the button, the bristles 22 will be bent away from the button
for making space for the button until the button has passed the region of the bristles
22, whereby the bristles 22 will move back into their normal position by their elasticity
and will now remain in the region between the button and the garment. The covering
member 10 is then pushed over the holding member 20 until a sufficiently strong press
fit between the covering member 10 and the holding member 20 is reached. For removing
the button cover 1 from the button on which it is mounted, the cover is simply pulled
away from the button against the elastic force of the bristles 22. The entire holding
member 20 may then be pulled out of the button covering member 10.
[0016] Various modifications to the above-described embodiment are possible. Instead of
being arranged in several regular rows, the bristles 22 may be arranged in an irregular
manner on the inside of the support 21. While a plurality of rows of bristles is preferred,
a single row of sufficiently strong bristles may be provided. The bristles need not
be arranged continuously all the way around the circumference, e.g., at least three
individual groups of bristles may be provided in different places around the circumference
of the inside of the support 21. This is illustrated in Fig. 5, where a holding member
20' is shown which has three groups of bristles 22 arranged at regularly spaced positions
along the circumference of the carrier 21, the spacing between the centers of the
groups being 120 degrees.
[0017] Instead of bristles, other shapes of elastic protrusions extending inwardly from
the perimeter region of the holding element may be used. Possible shapes include,
but are not limited to, elongated flat leaves or vanes. This is illustrated in Fig.
6, where a holding member 20" is shown which comprises a reinforcement element 24'
and, clamped into the reinforcement element, a flat, thin plate or leaf 26 made from
an elastic material such as spring steel or plastics. The plate 26 has an irregularly
shaped opening 27. The shape of this opening 27 defines three vanes 28 protruding
from the perimeter region of the holding member 20" inwardly towards its center. Of
course, other numbers and shapes of the vanes are possible.
[0018] While in the above embodiments the bristles or, in more general terms, the protrusions,
when in their normal position, extend essentially in a common plane parallel to the
plane defined by the support 21 (and therefore in parallel to the inner face 12a of
the covering member 10), it is also possible, e.g., that the protrusions are tilted
towards the inner face 12a of the cover portion 12, the protrusions together forming
an inwardly tapered configuration. It may be advantageous to "bias" the protrusions
in this manner in order to increase the required force for removal of the button cover
from the button. This "bias" tilt of the protrusions may be so strong that the free
ends of the protrusions touch the inner face 12a of the cover portion 12 when the
holding element is mounted in the covering element, if no button is present in the
cover, such that a button which is held within the button cover will be permanently
pressed towards the inner face 12a by the protrusions.
[0019] In a simplified embodiment, the entire holding element may be made in one piece from
the same material, without the use of a reinforcement element 24. To this end, the
material of the holding element should be selected to be sufficiently rigid and strong
in the peripheral region while still being sufficiently elastic to ensure that the
protrusions are sufficiently bendable. By the way of example, the entire holding element
may be manufactured from spring steel or from an elastic synthetic material like polyethylene.
[0020] In the above-described example, the sidewall 11 of the covering member 10 extends
along the full circumference of the cover portion 12. While this yields a pleasing
aesthetic appearance, it is also possible to have, e.g., several separate sidewall
portions along the circumference of the cover portion separated by slits. This may
be advantageous for improving the (in its nature elastic) press fit between the covering
member 10 and the holding member 20. Likewise, the ring-shaped support 21 of the holding
member 20 may be interrupted by a small gap making the holding member slightly elastically
compressible radially.
[0021] Instead of being held in place within the covering member 10 by a press fit, the
holding member 20 may be connected to the covering member 10 by other means, e.g.,
by a snap-in connection well known in the art or by a screw-in type connection. While
it is preferred that the holding member 20 is releasable from the covering member
10 for easy mounting, a permanent connection between these members is possible, and
whole button cover may even be formed in one piece.
[0022] While in the above-described examples the button cover has a circular shape, various
shapes of the button cover are possible, e.g., quadratic, hexagonal, octagonal, regularly
or irregularly polygonal, triangular, cross-shaped, heart-shaped etc. The shape of
the cover portion 12 of the covering member 10 may be entirely independent of the
shape of the sidewall 11 and the thus-defined shape of the holding element 20.
[0023] The button cover of the present invention may be used as part of a multifunctional,
modular jewelry system. To this end, an adapter for the button cover may be provided.
An example for such an adapter is shown in Fig. 7. The adapter 3 has a button-shaped
insert section 31. This insert section 31 is adapted for being received within a button
cover according to the present invention, i.e., it preferably matches in size and
shape the inside proportions of the button cover. A short, reduced-diameter stem section
32 is centrally connected to the insert section. This stem section 32 is adapted for
being passed through the central opening of the holding member of the button cover
which is left free by the protrusions. A safety pin 33 is connected to the stem section.
[0024] The adapter 3 may be inserted into the button cover in the same manner as a button
sewn to a garment, i.e., the insert section 31 replaces the button, and the stem section
32 replaces the thread. The button cover may thus be used as a brooch.
[0025] Instead of a safety pin 33, the adapter 3 may comprise other kinds of connection
means, e.g., an ear pin, an ear clip, a hanger for a necklace, etc. In this way, the
button cover may be used as a multi-purpose jewelry item, which vastly extends the
range of possible uses of the button cover.
[0026] The insert section need not be button-shaped. It is sufficient that the insert section
has lateral dimensions larger than the diameter of the central opening left free by
the elastic protrusions of the button cover.
[0027] In another application, two button covers may be connected to form a cuff link. To
this end, the adapter may comprise two (preferably button-shaped) insert sections
connected by a stem section. The insert sections may also be, e.g., approximately
ball-shaped, such that the overall appearance of the adapter would be bone-shaped.
The stem may be straight or bent. For forming a cuff link, each insert section is
received in a button cover.
[0028] The button cover according to the present invention and one or several adapters may
be sold together as a multifunctional jewelry system.
