[0001] The present invention relates to a merry-go-round. More particularly, the present
invention relates to a manually actuated merry-go-round, intended for semipermanent
installation and which makes it possible to actuate a large number of seats actuated
by a single person.
[0002] By semipermanent installation there is meant an installation which is non-final but
permanent for a long period of time, of days, weeks, or months, comprising overnight
periods of installation.
[0003] In particular, the merry-go-round which is the subject of the present invention is
composed of a podium from which projects a vertical rotating shaft which has on its
upper part a structure from which the seats of the merry-go-round are suspended, the
upper surface of the podium having a first circular platform section which is firmly
secured to the vertical shaft and surrounds the shaft, and a second platform section
coaxial to the first and which surrounds same, the merry-go-round also including a
pedal driving system connected to the second platform section, the pedals being connected
to a driving wheel in contact with the first platform section, such that the first
platform section is driven when the pedals are rotated, thus causing the vertical
shaft to rotate.
[0004] Preferably, the wheel drives the first platform section by means of friction by means
of the wheel being in contact with the first platform section.
[0005] Preferably, the amusement posts will be seats in a circular arrangement.
[0006] In accordance with the tests carried out, the system which is the subject of the
present invention makes it possible to drive a merry-go-round with twelve seats without
any great effort, due to the fact that the action of the pedals is not transmitted
directly to the vertical shaft, but is produced by means of the wheel being in contact
with the first platform section, at a point remote from the shaft, preferably on the
periphery of the aforementioned first platform section.
[0007] The merry-go-round of the present invention has the advantage of not requiring mechanical
transmission members which are heavy and require maintenance.
[0008] The braking system of the merry-go-round may be the conventional braking system for
braking a bicycle, that is, brake shoes which act on the driving wheel.
[0009] For its installation, the podium preferably has levelling means.
[0010] For greater understanding thereof, drawings of an embodiment of the merry-go-round
of the present invention are appended by way of non-limiting explanatory example.
Figure 1 is an end view in elevation of a merry-go-round according to the present
invention.
Figure 2 comprises a side elevation in which the upper decorative elements have been
removed and in which the internal elements of the podium are shown.
Figure 3 is a plan view from above in which the arrangement of the elements on the
podium is shown.
[0011] In the drawings can be seen an embodiment of the merry-go-round according to the
present invention which comprises a podium 4 from which projects a rotating shaft
1 formed, for example, by a cylinder 6 cm in diameter. Arranged in the upper part
of the shaft 1 is a structure 21 from which are suspended the seats 3 which are in
a circular arrangement. The structure 21 is concealed by an awning 21. The rotating
shaft is secured to the podium 4 by means of two stabilizing bearings 11, 12 located
at two points on the podium 4. The podium 4 also has stabilizers 43 in order to ensure
the true verticality of the shaft 1 and thus improved transmission of motion between
elements and improved functioning of the whole system.
[0012] The upper platform of the podium 4 is divided into two. Surrounding the rotating
shaft 1 there is a first platform section 41 which is circular and solidly connected
to same. Surrounding the first section 41 and coaxial thereto there is a second platform
section 42 which is fixed.
[0013] The drive is manual and in the case which is shown is provided by means of a modified
bicycle 5, on which the front wheel has been replaced by a structure 53 for fixing
to the second platform section 42, whereas the rear wheel 52 remains in contact with
the first platform section 41, at the periphery thereof.
[0014] In order to drive the merry-go-round, the user sits down on the saddle 51 and turns
the pedals 54, and the action of the pedals is transmitted by way of the chain 55
to the rear wheel 52 which, by friction, brings about the rotation of the assembly
consisting of the first platform section 41 and the rotating shaft 1.
[0015] The brake (not shown) is provided by means of a bicycle brake, based on two shoes
which brake the driving wheel 55.
[0016] In addition, the merry-go-round which is described may incorporate a system for counting
the number of passengers who make use of same.
[0017] The system can be located in the structure 21.
[0018] By means of the use of sensors based on parallel plate capacitors (or another equivalent
sensor) it is possible to detect an increase in weight of the seats 3 of, for example
15 kg, generating an electrical discharge which causes a counting apparatus, for example
of conventional type, to increase its count by one.
[0019] The counting apparatus may be provided with a system for transmitting to another
site the data stored in the counter, for example, in real time.
[0020] The energy required for the functioning of the counting system may, for example,
be provided by an electrical generator which transforms the rotational energy of the
merry-go-round into electrical energy, in conjunction with a battery.
[0021] Although the invention has been described with respect to preferred exemplary embodiments,
these should not be regarded as limiting the invention, which will be defined by the
widest interpretation of the following claims.
