TECHNICAL FIELD
[0001] The present invention relates to an apparatus for strengthening abdominal muscles.
The invention is especially related to an abdominal muscle apparatus by means of which
abdominal muscles can be strengthened without physical effort. In more detail the
invention relates to an apparatus according to the preamble of claim 1 for strengthening
abdominal muscles.
[0002] Abdominal muscles can be strengthened by means of apparatuses designed for physical
exercise or by means of apparatuses strengthening abdominal muscles without physical
exercise. The apparatuses for strengthening abdominal muscles without physical exercise
are based on electrical stimulation of abdominal muscles. The technique of electrically
stimulating causes active muscle contractions and tensions in the abdominal muscles.
This causes the muscle strands to contract, increasing abdominal muscles passively.
These abdominal muscle apparatuses feature a belt wearable around the, the belt being
provided with an apparatus causing contractions of abdominal muscles at the location
of the muscles. The electrical parts cause the apparatus to be complex to manufacture.
The apparatuses utilizing electric muscle stimulation technique cause the abdominal
muscles to contract only instantaneously and for a short time.
SHORT DISCLOSURE OF THE INVENTION
[0003] More specifically, the invention is characterized by what is disclosed in the characterizing
part of claim 1.
[0004] The purpose of the invention is to allow strengthening the abdominal muscles without
physical exercise.
[0005] The apparatus of the invention works by means of mechanical compression force causing
the protrusions of the body of the apparatus to compress against the abdominal muscles,
which in turn causes contraction of abdominal muscles. This means that a separate
electrical stimulation apparatus is not necessary, the apparatus is more simple to
manufacture and easier to use. The invention makes it possible to contract the abdominal
muscles continuously, in long cycles, enhancing the strengthening of the muscles.
This apparatus allows strengthening abdominal muscles without physical exercise, so
it is suitable for use in situations where physical exercise is not possible, such
as after an accident, when recuperating from an operation, while working in an office
with computers or during other activities. The apparatus is compact in size so it
can be used anywhere.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0007] Figure 1 illustrates an apparatus for strengthening abdominal muscles. As can be
seen in figure 1, the apparatus comprises a body 100 and means 102 attached to the
body. The apparatus for strengthening abdominal muscles comprises a body 100 placeable
on rectus abdominis muscles, the body comprising protrusions 101 that can be directed
on the rectus abdominis muscles of the left-hand and right-hand side, the protrusions
being vertically offset from each other so as to be aligned with both the right-hand
and left-hand side rectus abdominis muscles, and means 102 connected to the body and
capable of compressing the body against the abdominal muscles by means of a mechanical
compression force adapting to the movements of the user when the apparatus is being
worn by the user. These protrusions of the body are compressed against the abdominal
muscles and cause a contraction of the abdominal muscles.
[0008] Preferably the apparatus is worn on the waist of the user, whereby the user instinctively
tensions the abdominal muscles when the apparatus is worn and the body 100 compresses
against the abdominal muscles. The abdominal muscles are tensioned as long as mechanical
compression force is directed at the abdominal muscles. The tension level of the abdominal
muscles is directly related to the strength of the mechanical compression force produced
by the means 102. The level of the mechanical compression force can vary, so the apparatus
will yield during breathing, for example. Due to continuous compression force the
abdominal muscles are in constant tension so there is no rest period. Because of this,
a single utilization time for achieving the desired effect can be shorter than with
known apparatuses. The tension of abdominal muscles caused by the mechanical compression
force is at least partly involuntary and reflex-like so it is also well suitable in
situations where physical exercise is not possible, such as working in office with
computers or during domestic chores.
[0009] The body 100 can be a plate, a frame or other suitable support structure. The body
can be square, rectangular or elliptical in shape. The edges of the body can be rounded.
The size of the body can be adapted to approximately correspond with the width and/or
length of the rectus abdominis muscles. The width of the body can be from 10 cm to
20 cm and the height can be from 15 cm to 20 cm. The thickness of the body can be
from 0.5 cm to 2 cm. The body can be rigid and thus transmit the compression force
efficiently to the abdominal muscles.
[0010] The protrusions 101 in the body 100 can be evenly divided between the left-hand and
the right-hand side of the body. The protrusions can be arranged vertically on each
side of the body. Thus the sequence of the protrusions corresponds to the direction
of the abdominal muscles in vertical direction when the apparatus is being used. The
locations of the vertically arranged protrusions on the body can correspond with the
locations of rectus abdominis muscles or they can be derived from the locations of
the rectus abdominis muscles. The protrusions on the left-hand and right-hand sides
of the body can form pairs in horizontal direction, whereby each pair can be formed
by protrusions located on opposite sides of the body and adjacent each other. Preferably
the protrusions are located horizontally on the same level so that the compression
force is directed on essentially the same height on the abdominal muscles of both
the left-hand and right-hand side. Thus the sequence of the protrusions corresponds
with the location of the left-hand and right-hand abdominal muscles, when the apparatus
is used. If the body is square or rectangular, the protrusions can be arranged at
the corners of the body. The protrusions can be located equidistant from each other
and equidistant from the edges of the body.
[0011] The protrusions 101 can be hemispherical, bumps or dowels in shape. The protrusions
can be totally or partly integral with the body 100 or they can be fully or partly
fastened to the body during manufacturing. The body-side ends of the protrusions can
be flat. The outermost ends of the protrusions, alignable to the abdominal muscles
can be dull, rounded or flat. The protrusions can taper towards the end alignable
to the abdominal muscles. Tapering produces a strong structure for the protrusions
and the compression force can be directed to an area smaller than the area of the
body-side end on the abdominal muscles.
[0012] The protrusion 101 can have a flexible reserve, whereby it is adjusted according
to the shape of the torso of the user when the apparatus is being worn. The flexible
reserve can be realized at the end of the protrusion facing the abdominal muscles.
Additionally or alternatively the flexible reserve can be realized at the body-side
end of the protrusion. The flexible reserve makes the apparatus suitable for different
users. The flexible reserve can be realized by means of elastic material.
[0013] The protrusions 101 can be a mixture or different protrusions. The protrusions can
be different in shape and/or material, as described above. The protrusions on the
left-hand and right-hand sides of the body can form pairs in horizontal direction,
whereby each pair can be formed by protrusions located on opposite sides of the body
and adjacent each other. The pair of protrusions thus formed cam be formed by similar
protrusions. Use of different protrusions may allow individual distribution of compression
force directly into each rectus abdominis muscle.
[0014] In one embodiment the means 102 comprise a rubber band, a spring or a pressure apparatus.
The operation of the pressure apparatus can be based on compressed air or hydrostatic
pressure. Thus the apparatus can work by means of mechanical compression force adapting
to the movements of the user and formed by a rubber band, compressed air or hydrostatic
pressure. The rubber band can be a wide elastic band having a width of 10 cm to 15
cm. In unstretched condition its length can be from 60 cm to 100 cm and it is adjustable
to fit the waist of the user. The mechanical compression force can also be caused
by a spring being compressed when the apparatus is being worn. As the tension applied
to the abdominal muscles is caused by the mechanical compression force a separate
electrical stimulation apparatus is not necessary, the apparatus is more simple to
manufacture and easier to use.
[0015] In one embodiment the means comprise a cushion aligned with the back of the user
when the apparatus is being worn. The cushion is provided with a rubber band led back
to the cushion through holes or loops in the plate. Thus the cushion is fastened by
means of a rubber band around the waist of the user. The fastening between the cushion
and the rubber band can be released so that the length of the rubber band can be adjusted.
Thus the apparatus can be adjusted for users of different sizes. The releasable fastening
can be e.g. a sticker fastening. The sticker fastening can be realized as a hook and
loop fastening or hook and pillar fastening, known as Velcro fastening. The Velcro
fastenings can be located in the cushion and the rubber band so that the rubber band
can be fastened to different locations of the cushion, whereby the length of the rubber
band is adjustable. Rubber bands can be fastened to the cushion on both the right-hand
and left-hand side of the apparatus, whereby the cushion can be aligned towards the
back and the adjustability can be increased.
[0016] In one embodiment the apparatus comprises a body 100, in which the number of protrusions
101 on both sides of the abdominal muscles is 2, 3 or more. The protrusions can be
aligned to only some or to all abdominal muscles, however so that their number is
the same on both sides of the abdominal muscles. The protrusions on the left-hand
and right-hand side can form pairs in horizontal direction. There can also be more
protrusions for each abdominal muscle.
[0017] One embodiment of the apparatus comprises a body 100 that can be made of metal, plastic,
rubber, silicone, wood or composite by means of, for example, moulding. The body and
protrusions 101 can be made as a single piece of the same material. This makes for
a simpler structure, manufacturing and assembly of the apparatus. The body can also
be a combination of different materials. The body and/or protrusions can be coated
with a material, such as a textile, whereby it will be more pleasant to wear.
[0018] In one embodiment the body 100 and the protrusions 101 can be produced separately
and they can be of a different material. In this case they can be joined together
by a press joint, thread joint or by gluing. Producing separate parts allows a more
versatile use of materials.
[0019] In one embodiment the apparatus comprises an item of clothing, such as a shirt or
a jacket. Thereby the body 100 and the means 102 for producing mechanical compression
power can be integrated into the item of clothing already during manufacturing. The
body and means can be fixed or removable in the item of clothing by means of e.g.
zipper, buttons, snap fasteners or Velcro fasteners. In other words, the body and
the means can be attached to the shirt or jacket also after the production. It is
to be noted that one of the body and means can be fixed in the shirt or jacket and
the other can be removable.
[0020] Figures 2a to 2c illustrate an apparatus according to one embodiment for strengthening
the abdominal muscles, seen from the front and from above. Figures 2d to 2f illustrate
the second part of the body of the apparatus seen from different angles. As the figures
show, the apparatus comprises a body 100, protrusions 101, means 102, lock mechanism
200 and wings 500. The lock mechanism comprises a connector pair comprising a male
part 300 and a female part 400. The figures are provided with examples of the dimensions
of the apparatus according to the invention, with millimetres as units.
[0021] In one embodiment the body 100 comprises two parts, wherein the protrusions 101 having
an effect on right-hand and left-hand abdominal muscles are located in dedicated parts.
The apparatus comprises a lock mechanism 200 arranged in parts of the body 100, the
mechanism locking the parts to each other so that the shape of the body remains unchanged
when the apparatus is used. The lock mechanism makes the apparatus easier to wear
and the apparatus is easier to place on the right place for applying compression force
to abdominal muscles.
[0022] In one embodiment the lock mechanism 200 is located away from the protrusions 101
closest to the edge, such as the upper edge or lower edge, of the body 100. The parts
of the lock mechanism located on each part of the body comprise a male part 300 and
a female part 400 being mutually mirror symmetrical so that when the parts of the
body are joined together, the male parts are inserted into the female parts. The male
parts are at least partly flexible in a direction perpendicular to the direction of
insertion and the female parts are arranged to be tighter at the entrance holes for
the male parts than deeper than the entrance holes inside the female parts. Thus a
locking between the parts of body is achieved as the male parts expand when the male
parts are inserted into the female parts deeper than the entrance hole. Such a locking
is simple to produce and easy to use. The male parts, flexible in the insertion direction,
make it easier to push the male parts into the female parts.
[0023] In one embodiment the parts of the body 100 are laterally symmetrical and the lock
mechanism 200 in vertically in the middle of the apparatus between the protrusions
101. Thus the apparatus can easily be placed against the abdominal muscles and the
compression force is evenly distributed on both sides of the abdominal muscles.
[0024] In one embodiment each part of the body 100 comprises wings 500 extending laterally
in relation to the user, the wings acting as handles for manually directing the protrusions
101 symmetrically on the abdominal muscles. The wings facilitate handling of the apparatus
and placing the protrusions in correct places on the abdominal muscles.
[0025] In one embodiment the outermost ends of the protrusions 101 that can be aligned with
abdominal muscles are turned against each other in medial direction. Thereby the apparatus
follows better the curved shape of the torso and the compression force can be more
precisely placed on the abdominal muscles.
[0026] The apparatus according to the invention works by means of mechanical compression
force causing the protrusions of the body of the apparatus to compress against the
abdominal muscles, which in turn causes contraction of abdominal muscles. This means
that a separate electrical stimulation apparatus is not necessary, the apparatus is
more simple to manufacture and easier to use. The invention makes it possible to contract
the abdominal muscles continuously, in long cycles, enhancing the strengthening of
the muscles. This apparatus allows strengthening abdominal muscles without physical
exercise, so it is suitable for use in situations where physical exercise is not possible,
such as after an accident, when recuperating from an operation, while working in an
office with computers or during other activities. The apparatus is compact in size
so it can be used anywhere.
INDUSTRIAL APPLICABILITY
[0027] The apparatus for strengthening abdominal muscles is usable for both normal consumers
as well as amateur and professional athletes. The apparatus can be industrially produced,
whereby both its structure and effect can be reproduced. The apparatus can be used
in jackets and shirts to which the apparatus can be attached during manufacturing
or after the manufacturing.
