[Technical Field]
[0001] The present invention relates to a functional chair, and more particularly, to a
functional chair having a storage space for storing articles therein.
[Background Art]
[0002] In general, a chair has a backrest for allowing a user to lean back.
[0003] Recently, such a backrest serves not only to allow the user to lean but also to correct
the user's bad sitting posture and to protect the user's lumbar.
[0004] However, such a chair generally puts emphasis on protecting the user's lumbar and
does not have various functions. For instance, articles such as bags or carrying bags
must be stored in a desk, a bookshelf, or a separate storage space because the chair
does not have any storage space for storing the articles.
[0005] As described above, the conventional chair has several problems as follows because
it does not have any storage space.
[0006] First, if the user puts his or her bag on the floor, the bag may get dirty and cause
inconvenience to others. Of course, the user may put the bag on another chair, but
it causes reduction of chairs for others' seating.
[0007] Moreover, when the user seats on the chair, the user lays his or her outer clothing,
for instance, a coat or others, across the backrest of the chair. However, in the
case that the user lays his or her outer clothing across the backrest of the chair,
some of the outer clothing located at an area of the backrest where the user's back
touches may be creased due to the user leaning on the backrest of the chair.
[0008] Of course, the chair may have a hook mounted on a side or a rear side thereof so
as to allow the user to hang his or her outer clothing on the hook. However, some
of the outer clothing may touch the ground because height of the chair may be lower
than that of the outer clothing.

[Best Mode]
[0030] Reference will be now made in detail to the preferred embodiment of the present invention
with reference to the attached drawings. For convenience in description, the embodiments
will be described separately.
First Embodiment
[0031] FIGS. 1 to 3 illustrate a functional chair according to a first preferred embodiment
of the present invention.
[0032] As shown in the drawings, the functional chair 1 according to the first preferred
embodiment includes a sitting part 10 and a backrest part 20. The sitting part 10
provides a user a sitting area, and means an ordinary seat board.
[0033] Moreover, a plurality of chair legs 12 formed integrally with the bottom face of
the sitting part 10. However, the chair legs 12 may be manufactured separately from
the sitting part 10 and joined to the sitting part 10 like legs of an office chair.
Of course, in the case that the functional chair does not need chair legs like a legless
chair, the chair legs are not provided.
[0034] The backrest part 20 includes a first backrest 22 and a second backrest 24 which
are separated from each other. In this embodiment, the first backrest 22 and the second
backrest 24 are formed integrally at the rear of the sitting part 10. However, the
first backrest 22 and the second backrest 24 may be respectively joined to the sitting
part 10 after the sitting part and the backrest part 20 are manufactured separately.
In this case, the backrest part 20 must have a storage space 2 formed between the
separated backrests 22 and 24.
[0035] The first backrest 22 of the backrest part 20 is mounted upwardly on the sitting
part 10 and serves to support the back of the user who sits on the sitting part 10.
Furthermore, the second backrest 24 is located at the rear of the first backrest 22
and spaced apart from the first backrest 22, and hence, the storage space 2 is formed
between the first backrest 22 and the second backrest 24.
[0036] In this instance, an interval between the first backrest 22 and the second backrest
24 may be changed according to use purposes of the functional chair. In generally,
it is preferable that the interval between the first backrest 22 and the second backrest
24 is as long as the user can store a simple brief case (for instance, within a range
of 100mm to 200mm).
[0037] As shown in FIG. 2, the space formed by the interval between the two backrests 22
and 24 is used as the storage space 2. Accordingly, because the user can keep his
or her articles in the storage space 2 safely, there is no need to put the user's
bag or brief case on the ground or on another chair. Furthermore, the functional chair
prevents the user's bag from causing inconvenience to others and allows the user to
easily secure necessary seats.
[0038] Particularly, as circumstances demand, the backrest may be used as an area to lay
a coat across the backrest. In other words, as shown in FIG. 3, the user can lay his
or her coat across the second backrest 24 which forms the storage space 2. Then, even
though the user leans back against the first backrest 22 sitting on the chair, it
is prevented that the coat is creased.
[Mode for Invention]
[0039] In the meantime, the present invention is not restricted to the first embodiment
that the first backrest 22 and the second backrest 24 of the backrest part 20 are
spaced apart from each other to form the storage space 2. That is, the functional
chair may be formed in such a fashion that the storage space 2 is formed if the user
requires the storage space but is not formed if the user does not want the storage
space 2. It will be described in a second preferred embodiment.
Second Embodiment
[0040] FIG. 4 is an exploded rear perspective view of a functional chair according to a
second preferred embodiment of the present invention, and FIGS. 5 and 6 are rear perspective
views for explaining operational states of the functional chair by each situation
according to the second preferred embodiment of the present invention.
[0041] As shown in FIG. 4, the functional chair 3 includes a sitting part 30 and a backrest
part 40. The sitting part 30 provides a sitting area to the user. The sitting part
30 has a plurality of chair legs 32 formed on the bottom face thereof.
[0042] The backrest part 40 includes a first backrest 42 and a second backrest 44.
[0043] The first backrest 42 is perpendicularly formed at the rear of the sitting part 30
and serves to support the back of the user who sits on the sitting part 30.
[0044] The second backrest 44 is separated from or gets closer to the first backrest 42.
For this, a joining part 50 is provided. The joining part 50 has a front face rotatably
joined to a lower end of the first backrest 42 and a rear face rotatably joined to
a lower end of the second backrest 44 so as to provide a laying area for laying the
user's articles thereon, and includes a flat plate for separating the second backrest
44 from the first backrest 42. In this instance, in order to rotatably join the joining
part 50 and the backrests 42 and 44 with one another, some of corresponding portions
of the joining part 50 and the backrests 42 and 44 are overlapped, and the overlapped
portions are joined by hinges 52 and 54. Of course, the structure to rotatably join
the joining part 50 and the backrests 42 and 44 with one another may be achieved by
another hinge-coupling structure.
[0045] In order to keep a close contact state between the first backrest 42 and the second
backrest 44, a contact-keeping part 60 is formed. The contact-keeping part 60 is to
prevent the second backrest 44 from being separated from the first backrest 42 unintentionally,
and includes a pair of magnets 62 and 64 correspondingly formed on the rear face of
the first backrest 42 and on the front face of the second backrest 44. Of course,
the contact-keeping part 60 may be constructed of a retaining ring and a retaining
groove respectively formed at corresponding portions of the two backrests 42 and 44.
[0046] The functional chair according to the second preferred embodiment may selectively
provide a storage space 4 between the first backrest 42 and the second backrest 44.
That is, if the storage space 4 is not needed, as shown in FIG. 5, the joining part
50 gets closer to the rear face of the first backrest 42, and simultaneously the second
backrest 44 also gets closer to the rear face of the first backrest 42. Then, the
storage space 4 is not provided, and hence, the functional chair can secure a wider
back and forth interval between chairs because a back and forth width of the functional
chair is relatively narrow.
[0047] On the other hand, if the user wants the storage space 4, as shown in FIG. 6, the
storage space 4 is formed when the second backrest 44 is separated from the first
backrest 42. That is, when the second backrest 44 is spaced apart from the first backrest
42, the joining part 50 is laid at right angles to the first backrest 42 to form an
area to put the user's articles, for instance, a bag or others, thereon, and the second
backrest 44 upwardly stands in a state where it is space apart from the rear face
of the first backrest 42 by the joining part 50 to thereby prevent that the articles
stored in the storage space 4 fall unintentionally.
[0048] Of course, the second backrest 44 also serves as a portion where the user lays his
or her coat.
[0049] In the meantime, in the second preferred embodiment, just one second backrest 44
is formed, but a plurality of second backrests 44 may be formed. In other words, the
joining part 50 may be additionally joined to the rear face of the second backrest
44 to thereby form a plurality of the storage spaces.
[0050] Additionally, the joining part 50 is the flat plate, but the joining part 50 may
be connected between the first backrest 42 and the second backrest 44 with a minimum
area and the rest may be opened (not shown in the drawings). For instance, just the
edges of the first backrest 42 and the second backrest 44 are connected with each
other using a bar-type connection member. The reason is to prevent the user's coat
from creasing since some of the coat extends downwardly when the user lays a long
coat across the storage space 4.
Third Embodiment
[0051] FIG. 7 is a rear perspective view of a functional chair according to a third preferred
embodiment of the present invention, and FIG. 8 is an exploded perspective view showing
a state where a partition member of FIG. 7 is separated.
[0052] As shown in FIGS. 7 and 8, the functional chair 110 includes a sitting part 112.
The sitting part 112 is an area for allowing the user to sit on. The sitting part
112 includes a plurality of chair legs 114 formed on the bottom face of the sitting
part 112. Of course, the chair legs 114 may be excluded, and may adopt any form that
can separate the sitting part 112 from the floor to a predetermined height.
[0053] The functional chair further includes a backrest part 116 perpendicularly stands
at the rear of the sitting part 112. The backrest part 116 includes a first backrest
118 and a second backrest 119 which are spaced apart from each other. An interval
between the first backrest 118 and the second backrest 119 may be changed according
to use purposes of the functional chair. The first backrest 118 is disposed on the
sitting part 112 and serves to support the back of the user who sits on the sitting
part 112. The second backrest 119 is located at the rear of the first backrest 118
and forms a storage space by being separated from the first backrest 118.
[0054] The chair legs 114 and the first and second backrests 118 and 119 may be formed integrally
with the sitting part 112 or formed detachably from the sitting part 112.
[0055] A partition member 120 is disposed in the storage space 117 formed between the first
backrest 118 and the second backrest 119. The partition member 120 serves to partition
the storage space 117 into several spaces.
[0056] The partition member 120 may have any shape to partition the storage space 117. For
instance, the partition member 120 may be a bar formed just at the edge or a flat
plate. Of course, another shape is also possible. That is, the partition member 120
can have any shape if it can partition the storage space 117. Moreover, the partition
member 120 may have the same height as the first backrest 118 and the second backrest
119 or have a height different from the height of the first backrest 118 and the second
backrest 119. Of course, the height of the first backrest 118 may be different from
the height of the second backrest 119.
[0057] The partition member 120 needs not to be formed integrally with a bottom face 115
which provides the storage space 117. In other words, it is preferable that the partition
member 120 is detachably attached to the inside of the storage space 117. For instance,
the storage space 117 has a joining hole 122 formed in the bottom face 115 of the
storage space 117 and the partition member 120 has a joining protrusion 124 formed
on the bottom face of the partition member 120 corresponding to the joining hole 122,
so that the partition member 120 can be attached or detached as occasion demands.
Then, the storage space 117 can be divided into several spaces, or the several storage
spaces can be united into one. Accordingly, the user can adjust the size of the storage
space 117 according to a size of the article to be stored in the storage space.
[0058] The functional chair 110 having the above structure allows the user to store various
articles in the storage space 117 formed on the backrest part 116, and to dividedly
store different articles in the storage spaces partitioned by the partition member.
In addition, the user can lay his or her clothing across the second backrest 119 or
the partition member 120.
Fourth Embodiment
[0059] FIG. 9 is a rear perspective view of a functional chair according to a fourth preferred
embodiment of the present invention, and FIGS. 10 to 13 are exemplary views showing
examples of the functional chair according to the fourth preferred embodiment of the
present invention.
[0060] As shown in FIG. 9, the functional chair 130 according to the fourth preferred embodiment
includes a flat type member 131 elongated in a longitudinal direction. Hereinafter,
the flat type member 131 is described as a 'sitting part'. A part of the sitting part
131 is allotted as a sitting area, and the reference numeral '132' in the drawings
is designated as the sitting area.
[0061] A plurality of chair legs 133 are formed on the bottom face of the sitting part 131.
[0062] A backrest 134 upwardly and vertically stands at an approximately middle portion
of the sitting part 131 to support the back of the user who sits on the sitting area
132. The backrest 134 may be formed integrally with the sitting part 131 or joined
and fixed to the upper face of the sitting part 131 via bolts or other medium, such
as adhesives.
[0063] The functional chair 130 further includes a plurality of vertical members 136 and
138 upwardly standing at a position spaced apart from the rear face of the backrest
134 at a predetermined interval. The vertical members 136 and 138 serve to provide
a storage space for storing the user's articles on the sitting part 131. In this embodiment,
there are two vertical members. In the drawings, the reference numeral '136' designates
a first vertical member, and '138' designates a second vertical member. Of course,
in consideration of the length of the sitting part 131, the size of the sitting area
132, the width of the storage space, and others, it will be obvious that at least
one vertical member may be disposed. In relation with the storage space formed by
the two vertical members 136 and 138, the reference numeral '137' designates a first
storage space, and '139' designates a second storage space.
[0064] The first vertical member 136 and the second vertical member 138 are fit to a cut
area formed in the sitting part 131 by means of the hinge method and have a structure
to be rotatable at a predetermined angle. Namely, some of a corresponding part between
the vertical members 136 and 138 and the sitting part 131 are overlapped with each
other, and the overlapped portions are joined by a hinge 140. Of course, they can
be joined by another structure besides the hinge.
[0065] The rotational angle of the vertical members 136 and 138 is determined by positions
of the backrest 134 and other neighboring vertical members, sizes of articles to be
stored in the storage space, and others. For instance, as shown in FIG. 10, in the
case that there is no article in the first storage space 137, the first vertical member
136 is rotatable till it touches the rear face of the backrest 134. On the other side,
not shown in the drawings, but in the case that there is an article in the first storage
space 137, one end of the first vertical member 136 may not touch the rear face of
the backrest 134 according to the size of the article to be stored. Likewise, the
second vertical member 138 also touch the rear face of the adjacent first vertical
member 136 or does not touch the rear face of the first vertical member 136 according
to whether or not there is an article in the second storage space 139.
[0066] In the meantime, the second vertical member 138 is limited in its rotational angle
in the direction of the first vertical member 136. That is, when the second vertical
member 138 is rotated in the direction of the first vertical member 136, it is rotated
within a range of a predetermined angle according to whether or not there is an article
in the second storage space 139 and according to the position of the first vertical
member 136. On the other hand, the second vertical member 138 may be rotated more
freely in a different direction against the second vertical member 138, namely, in
the opposite direction of the first vertical member 136.
[0067] FIGS. 11 to 13 illustrate examples of various rotations of the second vertical member
138.
[0068] FIG. 11 illustrates a state where the second vertical member 138 is in line with
the sitting part 131. The above may be used when there is no need to provide the second
storage space 139 or when the article to be stored in the second storage space 139
is long. In this instance, not shown in the drawings, but at least one receiving recess
may be formed on the rear face of the second vertical member 138 and a rotational
support bar is provided to one end of the receiving recess, so that the second vertical
member 138 can be supported by the support bar when the second vertical member 138
is completely stretched as shown in FIG. 11.
[0069] FIG. 12 illustrates a state where the second vertical member 138 is utilized as an
auxiliary leg. In other words, the user may store his or her article on the first
storage space 137 or the second storage space 139 without sitting on the functional
chair 130. In this instance, in the case that the article to be stored is heavy, the
weight center goes toward the rear face of the backrest 134, and thereby, the functional
chair 130 may fall backward. Accordingly, the second vertical member 138 is rotated
at an angle of 180 degrees, so that one end is in contact with the bottom face. Of
course, in this case, the second vertical member 138 must be equal in length with
the chair legs 133.
[0070] Here, the function of the second vertical member 138 as the auxiliary leg is not
essentially needed. The reason is that the functional chair 130 can sufficiently bear
the weight of the stored article even though the user may store his or her article
on the first storage space 137 or the second storage space 139 without sitting on
the sitting part 131 of the functional chair 130. Therefore, the function as the auxiliary
leg is provided to use the functional chair 130 more stably.
[0071] FIG. 13 illustrates a structure that the second vertical member 138 is located beneath
the sitting part 131. It is utilized in the case that there is no need to form the
second storage space 139 by the second vertical member 138 or that the second vertical
member 138 is not used as the auxiliary leg.
[0072] As described above, in the fourth preferred embodiment, the functional chair 130
has a plurality of the storage spaces 137 and 138 by the vertical members 136 and
138 formed on the sitting part 131. Moreover, the vertical member farthest from the
backrest 134 may be the storage space in itself or may be utilized as the auxiliary
leg.
Fifth Embodiment
[0073] In the fifth embodiment, the vertical member for forming the storage space is not
exposed to the outside but mounted under the sitting part.
[0074] Referring to FIGS. 14 to 16, the fifth preferred embodiment will be described. FIG.
14 is an exploded perspective view of a functional chair according to a fifth preferred
embodiment of the present invention, and FIGS. 15 and 16 are views showing examples
that the functional chair according to the fifth preferred embodiment of the present
invention is used.
[0075] As shown in the drawings, the functional chair 160 according to the fifth preferred
embodiment includes a sitting part 161 where the user can sit.
[0076] The functional chair has chair legs 162 formed at edges of the bottom face of the
sitting part 161 so that the sitting part 161 is spaced apart from the floor.
[0077] The functional chair further includes a backrest 163 which upwardly stands at the
rear of the sitting part 161 and supports the back of the user who sits on the sitting
part 161. The backrest 163 may be formed integrally with the rear of the sitting part
161 or formed separately.
[0078] A pair of guides 165 are mounted on the bottom face of the sitting part 161 in a
longitudinal direction in such a fashion that a vertical member 170 is slidably mounted.
The guides 165 may have one of various forms, but must have a structure that the guides
165 can be joined to the bottom face of the sitting part 161. Additionally, the guides
165 surround some of the sides of the vertical member 170 to prevent the vertical
member 170 from falling downwardly. In the drawings, the guides 165 are respectively
in the form of an approximately '

' shape. Here, not shown in the drawings, the sitting part 161 may have a space portion
of a predetermined size formed therein and guides formed at both sides of the space
portion in the same form as the guides 165, so that the vertical member 170 can be
slidably moved inside the space portion.
[0079] Each of the guides 165 has a long guide groove 166. The guide groove 166 together
with retaining protrusions 173, which will be described later, serve to prevent that
the vertical member 170 is separated forward and backward from the sitting part 161
when the vertical member 170 moves along the guide 166.
[0080] The vertical member 170 has a body 171 like a flat plate. The retaining protrusions
173 are formed on both sides of one end of the body 171. As described above, the retaining
protrusions 173 and the guide grooves 166 serve to prevent the vertical member from
being separated from the guides 165.
[0081] An upper bracket 175 which forms a part of the upper face of the body 171 is joined
to the other end of the upper face of the body 171 by a hinge 176. The body 171 where
the upper bracket 175 is located may have an interior space formed therein for storing
the user's article therein.
[0082] Referring to FIGS. 15 and 16, the examples that the functional chair according to
the fifth preferred embodiment of the present invention is used will be described.
[0083] First, as shown in FIG. 15, the user pulls the vertical member 170 mounted on the
bottom face of the sitting part 161 in the direction of the rear face of the backrest
163. Then, the retaining protrusions 173 formed at the sides of the vertical member
170 moves along the guide grooves 166, and thereby, the vertical member 170 is drawn
out. The user can pull the vertical member 170 till the retaining protrusions 173
touch one end of the inner face of the guide groove 166.
[0084] In the above state, the user rotates the upper bracket 175 on the hinge 176. In this
instance, the rotational angle may be adjusted in various ways, but in this embodiment,
is at right angles to the sitting part 161. It is illustrated in FIG. 16. As shown
in FIG. 16, when the upper bracket 175 stands and is spaced apart from the rear face
of the backrest 163 at a predetermined interval, the storage space 178 is formed between
the upper bracket 175 and the backrest 163.
[0085] Then, the user can store his or her article in the storage space 178.
[0086] Of course, also in the case that the upper bracket 175 forms a part of the upper
face of the body 171 without being rotated, the user can store his or her article
in the interior space formed inside the body 171 or on the upper face of the upper
bracket 175.
[0087] Moreover, if the user does not want the storage space 178 or when the user completes
storing the article in the interior space of the body 171, the user pushes the vertical
member 170 in such a fashion that the vertical member 170 is located beneath the sitting
part 161.
[0088] In the meantime, in the fifth preferred embodiment, the vertical member 170 is drawn
out toward the rear face of the backrest 163, but another example is also possible.
For instance, the vertical member 170 mounted beneath the sitting part 161 may be
drawn out from the side of the sitting part 161. In this instance, the user can store
his or her article on the upper face of the vertical member 170 or in the storage
space formed by the upper bracket 175 rotated. Furthermore, the vertical member 170
may be drawn out from the front of the sitting part 161. Of course, in this instance,
the user cannot form the storage space by making the upper bracket 175 stand because
the user has to sit on the sitting part 161. However, if the user does not sit on
the sitting part 161, the user can store his or her article on the upper face of the
vertical member 170 or in the storage space formed by the upper bracket 175 rotated.
[0089] As described above, in the fifth preferred embodiment, the functional chair has the
vertical member 170 mounted beneath the sitting part 161 to form the storage space,
and as occasion demands, the vertical member 170 is drawn out to thereby form the
storage space. Additionally, the functional chair can utilize a space widely because
the vertical member 170 is drawn out not only from the rear face of the backrest 163
but also the side or the front of the sitting part 161 to provide the storage space.
Of course, in the case that the user does not want the storage space or the chair
is located in a limited space, because the vertical member 170 is located beneath
the sitting part 161, there is no inconvenience due to the vertical member 170.
[0090] In the meantime, the structure that the vertical member 170 is slidably moved may
be achieved by various structures besides the above structure. For instance, the drawer
structure of a general desk, which has rails and wheels rolling along the rails, may
be adopted.
Sixth Embodiment
[0091] Referring to FIGS. 17 to 20, the sixth preferred embodiment will be described.
[0092] FIG. 17 is an exploded perspective view of a functional chair according to a sixth
preferred embodiment of the present invention, and FIGS. 18 to 20 are views showing
examples that the functional chair according to the sixth preferred embodiment of
the present invention is used.
[0093] As shown in FIG. 17, the functional chair 180 according to the sixth preferred embodiment
includes a sitting part 181 for allowing the user to sit on. The functional chair
180 further includes chair legs 182 formed on the edges of the bottom face of the
sitting part 181 toward the floor, so that the sitting part 181 is spaced apart from
the floor.
[0094] The functional chair 180 has a backrest 183 upwardly standing at the rear of the
sitting part 181 for supporting the back of the user who sits on the sitting part
181. The backrest 183 may be formed integrally with the sitting part 181 or formed
separately.
[0095] The sitting part 181 has a receiving portion 185 formed therein. The receiving portion
185 is formed inside the sitting part 181 of a predetermined thickness, and has an
entrance 186 formed on one side where the backrest 183 is located so as to allow a
vertical member 190, which will be described later, to go in and out.
[0096] The receiving portion 185 has retaining holes 187 arranged on at least one inner
side of the receiving portion 185. The vertical member 190 has protrusions 192 formed
on the outer face thereof and the protrusions 192 are inserted into the retaining
holes 187. Through the retaining holes 187 and the protrusions 192, the vertical member
190 does not move inside the receiving portion 185 and can keep a fixed state to some
degree even though some of the vertical member 190 is drawn out from the receiving
portion 185.
[0097] The vertical member 190 is mounted in the receiving portion 185. The vertical member
190 has a plate type body 191 of a predetermined thickness. The body 191 has a plurality
of bodies 191a, 191b, 191c and 191d. Moreover, each of the bodies 191a, 191b, 191c
and 191d has a structure to be bendable against the neighboring body. Such a structure
is achieved by the hinge-coupling method. Here, it is not necessary that the body
191 of the vertical member 190 has the four bodies 191a, 191b, 191c and 191d. Namely,
the number of the bodies may be changed according to the length of the sitting part
181.
[0098] The protrusions 192 are formed on the side of the body 191. The protrusion 192 has
an elastic member like a spring 193 provided to the rear face thereof. So, when the
vertical member 190 moves, the protrusions 192 are inserted into the retaining holes
187 or received into the body 191.
[0099] Meanwhile, in the sixth preferred embodiment, it is not necessary to form the receiving
portion 185 in the sitting part 181. In other words, like the fifth preferred embodiment,
a bracket is additionally mounted on the bottom face of the sitting part 181 so that
the vertical member 190 is movable.
[0100] Referring to FIGS. 18 to 20, the operation of the sixth preferred embodiment having
the above structure will be described.
[0101] Ordinarily, the vertical member 190 is located inside the receiving portion 185.
In this case, the protrusions 192 are respectively accommodated in the retaining holes
187, and hence, the vertical member 190 does not come out unless an external force
is applied to the vertical member 190.
[0102] In the case that the user who sits on the functional chair 180 has articles, such
as a bag, documents, clothes or others, there is a need to form a storage space. For
this, as shown in FIG. 18, the user grasps one end of the vertical member 190 accommodated
in the receiving portion 185 and pulls the vertical member 190 in the direction of
the rear face of the backrest 183. Then, the vertical member 190 comes out from the
receiving portion 185.
[0103] As shown in FIG. 19, when only the body 191a out of the bodies 191a, 191b, 191c and
191d of the vertical member 190 completely comes out, the user rotates only the body
191a. Then, the storage space 195 is formed between the body 191a and the backrest
183. So, the user can store his or her article in the storage space 195. Of course,
because the storage space 195 is rotated in a state where only the body 191a comes
out, it is lower in height than the backrest 183. Therefore, it is good to store articles
appropriate to the size of the storage space 195.
[0104] If the user wants a storage space greater than the storage space 195 shown in FIG.
19, the user pulls the vertical member 190 more and rotates the corresponding body.
In other words, FIG. 20 illustrates a state where the bodies 191a and 191b out of
the bodies 191a, 191b, 191c and 191d of the vertical member 190 completely come out.
So, the bodies 191a and 191b are rotatable. It means that a storage space 196 which
is greater or higher than the storage space 195 of FIG. 19 can be formed.
[0105] As described above, in the sixth preferred embodiment, the vertical member for forming
the storage space may be varied in height.
[0106] In the meantime, in order to remove the storage spaces 195 and 196 shown in FIGS.
19 and 20, the user rotates the body vertically standing in the opposite direction
till the body is in line with the sitting part 181, and then, forcedly pushes the
body into the receiving portion 185.
Seventh Embodiment
[0107] Referring to FIGS. 21 and 22, the seventh preferred embodiment will be described.
[0108] FIG. 21 is a rear perspective view of a functional chair according to a seventh preferred
embodiment of the present invention, and FIG. 22 is a view showing an example that
the functional chair according to the seventh preferred embodiment of the present
invention is used.
[0109] As shown in FIG. 21, the functional chair 200 includes a sitting part 201 for allowing
the user to sit on.
[0110] The functional chair 200 further includes chair legs 203 formed at the edges of the
bottom face of the sitting part 201, so that the sitting part 201 is spaced apart
from the floor.
[0111] The functional chair 200 further includes a backrest 205 upwardly standing at the
rear of the sitting part 201 for supporting the back of the user who sits on the sitting
part 201. The backrest 205 may be formed integrally with the rear of the sitting part
201 or formed separately.
[0112] The backrest 205 has a vertical member 207 disposed on the rear face thereof for
forming a storage space. The vertical member 207 has a body of an approximately '

' shape. Some of the body forms the rear face of the backrest 205 and the other of
the body is accommodated in a space portion (not shown) formed inside the sitting
part 201.
[0113] The functional chair according to the seventh preferred embodiment is used as follows.
[0114] FIG. 21 shows a common state of the chair. In this case, the functional chair 200
serves as a chair.
[0115] However, when the user wants to store his or her article in the chair, the user pulls
the vertical member 207 formed on the rear face of the backrest 205 in the backward
direction of the functional chair 200.
[0116] FIG. 22 illustrates the above state. When the user pulls the vertical member 207,
the vertical member 207 is spaced apart from the rear face of the backrest 205.
[0117] Accordingly, a storage space 209 is formed by the backrest 205 and the '

'-shaped vertical member 207, and the user can store his or her article in the storage
space 209.
[0118] Here, the vertical member 207 is in the state where some of the body is accommodated
inside the sitting part 201. So, the vertical member 207 is supported by the sitting
part 201, and hence, can form the storage space 209.
[0119] Meanwhile, the sitting part 201 may have retaining jaws formed therein to prevent
that the vertical member 207 completely comes out from the sitting part 201.
[0120] Furthermore, it is obvious that the structure to move the vertical member 207 from
the sitting part 201 may adopt one of various structures described in the fifth preferred
embodiment and the sixth preferred embodiment.
[0121] As described above, the functional chair according to the present invention has at
least one storage space to allow the user to store his or her article in the chair.
[0122] As described above, while the present invention has been particularly shown and described
with reference to the example embodiments thereof, it will be understood by those
of ordinary skill in the art that the above embodiments of the present invention are
all exemplified and various changes, modifications and equivalents may be made therein
without changing the essential characteristics and scope of the present invention.
