Device for teaching swimming
Abstract
A device for swimming learning includes an L-like frame having
an upright portion standing along a swimming pool and a lateral
portion extending above the swimming pool. A connector is mounted
movably on the lateral portion. A first elastic strap is pivotally
mounted on the lateral portion of the frame. A second elastic strap
is connected pivotally to the connector. A buoy is connected to the
first elastic strap and the second elastic strap. Whereby, a
swimmer can be suspended on the surface of the pool in order to
develop swimming techniques and remain at a stationary position due
to resilient forces of the first and the second elastic strap
therefore preventing the swimmer from moving forward to a deep area
of the swimming pool.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a device for teaching
swimming, and particularly to a device which enables a user to
easily gather breath and perform the correct swimming posture.
[0003] 2. Description of Related Art
[0004] Swimming is a particularly healthy exercise, yet many people
are afraid to learn because they do not know how to gather breath
or to float on water, and greatly fear choking and drowning.
[0005] Additionally, a swimmer must coordinate movements of arms
and legs to go forward in the water. If a learner carelessly goes
to a deep area of a swimming pool and can not touch the bottom of
swimming pool, the learner will probably panic and lose the
confidence to continue with this exercise.
[0006] Therefore, the invention provides a device for teaching
swimming to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide a
device for teaching swimming which can enable a user to safely
perform the correct swimming posture and gather breath.
[0008] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] With reference to FIGS. 1 and 3, a device for teaching
swimming comprises an L-like frame (10) which has an upright
portion standing along a swimming pool (20) and a lateral portion
laterally extending from the upright portion and adapted for
extending above the swimming pool (20). The lateral portion has two
sides, and a longitudinal rail groove (104) defined in one of the
sides of the lateral portion. A connector extends movably through
the longitudinal rail groove (104) of the lateral portion of the
L-like frame (10). The connector has an L-like bar (14) and a wheel
(15). The L-like bar (14) extends through the longitudinal rail
groove (104) in the lateral portion and has a lower end and an
upper end extending into the longitudinal groove (104) in the
lateral portion. The wheel (15) is mounted rotatably at the upper
end of the L-like bar (14) and is located in the longitudinal rail
groove (104). A first elastic strap (11) is connected pivotally to
the lower end of the L-like bar (14). A second elastic strap (12)
is mounted pivotally on the upright portion of the frame (10), with
a buoy (13) connecting the first and the second elastic strap (11,
12). The buoy (13), which can be wrapped about a waist of a
swimmer, has a ring (130) mounted around an outer periphery thereof
to connect the first and second elastic strap (11, 12). A first
sling (110) is mounted pivotally at the lower end of the L-like bar
(14) and is connected to the first elastic strap (11). A second
sling (120) is mounted pivotally on the upright portion of the
frame (10) and is connected to the second elastic strap (12).
[0016] A seat (100), which is defined with multiple holes, is
mounted on a bottom end of the upright portion of the frame (10) so
that multiple fasteners are respectively inserted into the holes to
install the frame (10) along the swimming pool (20). A plurality of
orifices (103) is respectively evenly defined in the upright
portion of the frame (10) so that the second sling (120) can be
optionally inserted into the corresponding orifices (103) to adjust
position of the second elastic strap (12) on the frame (10).
[0017] With reference to FIG. 2, a second preferred embodiment of
the device for swimming learning is similar to the first preferred
embodiment except that a heavy block (102) is mounted on the seat
(100) to install the frame (10) further stably.
[0018] With reference to FIGS. 4-6, the first and the second
elastic strap (11, 12) are linked with the ring (130) of the buoy
(13) which is wrapped about the waist of the swimmer at first. An
extending length of the first elastic strap (11) due to a weight of
the swimmer is approximately equal with a vertical distance between
the lateral portion of the frame (10) and water surface so that the
swimmer can keep floating on the water. With reference to FIG. 4,
the swimmer swims forward for a short distance with the connector
moving along the longitudinal rail groove (104) in the lateral
portion. With reference to FIG. 5, the swimmer swims at a
stationary position due to the resilient forces of the first and
the second elastic strap (11, 12) when the connector reaches a
front end of the lateral portion. Therefore, the first and second
straps (11, 12) prevent the swimmer from moving forward to a deep
area of the swimming pool (20).
[0019] Alternatively, the frame (10) can have a heavy base
integrally formed at a bottom of the upright portion thereof for
movably disposing the frame (10) beside the swimming pool. The
heavy base has multiple wheels at a bottom thereof, so it is
convenient to remove the frame (10) from the swimming pool when not
in use.
[0020] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
