Abstract
A tire compacting apparatus to compress a conventional tire includes a modular frame upon which a rotating apparatus and a gripping apparatus are attached. The rotating apparatus is mounted to the proximal side of the frame and includes a servomotor having a drive shaft. The drive shaft is connected to a proximal clamp which initially engages the sidewalls of the tire. The gripping apparatus is attached to the distal side of the frame and includes an actuator with a piston. The piston is connected to a distal clamp that grips the sidewalls of the tire opposite the proximal clamp. Once the distal clamp has engaged the tire, the servomotor of tire rotating apparatus will be set in motion, such that the drive shaft will begin rotation in the desired direction. The rotation of the drive shaft will cause rotation of the proximal clamp. Since the distal clamp is kept substantially rigid, the tire will be coiled about the central axis, and a series of locking belts will be affixed around the compacted tire to ease transport and disposal of the tire.
Description
FIELD OF THE INVENTION
The present invention relates to an apparatus and method for modifying tire configurations for preparing tires for storage, for transport, and for disposal, and more specifically, to an apparatus for stretching and twisting tires into a smaller compound that facilitates storage, transport, and disposal of the compacted tires.
BACKGROUND OF THE INVENTION
It is well known that the disposal of conventional vehicular tires provides an environmental and aesthetic dilemma. Dumped tires are an eyesore in the landscape, and they can create environmental hazards. Many pests—mosquitoes primarily—breed in stagnant water that collects inside the tires. Several varieties of mosquitoes can carry deadly diseases, including encephalitis. Another major threat to our health and our environment is tire fires. They are difficult to put out, so they can burn for long periods of time. Huge, thick clouds of black smoke and oily residue from burning tires can cause contamination and discomfort.
Moreover, burying conventional tires is not satisfactory, as buried tires may rise to the surface of the soil. Presently, tires are disposed of in above-ground dumps, but this is not a satisfactory solution. It creates a large mound of tires, which becomes a hazard if a fire is ignited. Burning tires will release dangerous pollutants and are difficult to extinguish.
Environmentally, disposal of such tires provides a significant problem since tires are generally made of a synthesized rubber that does not decompose when disposed. Moreover, conventional tires generally weigh between 10 and 75 pounds and are very bulky, thus making such tires difficult to manage. Tires in the conventional shape have less bulk density than other waste items, and as a result they tend to rise to the top of landfills. The annual quantity of tires disposed averages one tire for each person in the country. The volume of space required to store the tire would be greatly reduced with a compacted tire. Since space is a premium for a tire dealer, by compacting the faulty tires for storage until they are picked up for disposition would greatly improve their available floor space.
Various solutions have been ascertained to provide for the proper disposal of tires. One solution is to use tires to make a variety of items. For example, rubber modified asphalt (RMA), a by-product of scrap tires, can be used for running track and road construction. In addition, scrap tires can be processed into chips for use in industrial boilers and in alternative playground bases as a floor surface.
What is desired, then, and not found in the prior art, is a tire compacting apparatus that is able to minimize the size of tires for disposal to allow the tires to be discharged.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an apparatus for compacting tires.
A further object of the present invention is to provide an apparatus to securely hold a compacted tire.
An additional object of the present invention is to provide a means for securing a compacted tire in the compacted position.
Yet another object of the present invention is to provide an apparatus for preparing a tire to be compacted.
A further object of the present invention is to provide a means for compressing a tire to aid in the handling and disposal of the tire.
The tire compacting apparatus of the present invention will compress a conventional tire, which will facilitate simple removal or destruction of the tire. The tire compacting apparatus includes a modular frame upon which a tire rotating apparatus and a tire gripping apparatus are attached. The tire rotating apparatus is mounted to the proximal side of the frame, and includes a servomotor or other driving means (such as a hand crank) having a drive shaft that is preferably connected to a drive assembly. The drive shaft is connected to a proximal tire clamp that is used to engage the sidewalls of the tire. In particular, the proximal tire clamp will securely grip and even penetrate the sidewalls of the tire such that the tire will move only pursuant to the movement of the proximal tire clamp. The clamps will be able to adjust to engage varying-sized tires, and the tension on the clamps will be mechanical, such as by a threaded screw-rod, by spring-loaded clamps, or by a hydraulic or pneumatic cylinder connected to one of the clamps.
The tire gripping apparatus is attached to the distal side of the frame. The tire gripping apparatus preferably includes an actuator, such as a hydraulic cylinder or a pneumatic cylinder, that has a piston, although other embodiments may be included such as an electric screw or a mechanical apparatus that has the ability to adjust to the diameter of the tire. The position of the actuator is maintained using a support brace that is connected between the actuator and the distal side of the frame. The piston is connected to a clamp rod, which is slidably mounted to the distal side of the frame via a set of bearings. The end of the clamp rod opposite the actuator is connected to a distal tire clamp that will securely grip and even penetrate the sidewalls of the tire opposite the proximal tire clamp. It should further be noted that although the preferred embodiment of the tire clamp is a conventional claw or clamp, other means for providing a secure and locked connection with the tire, such as a hook or chain, may be incorporated into the present design. Such embodiments must simply hold and control the tire in a secure fashion. Once the distal tire clamp has engaged the tire, the operator will be able to compress the tire as desired.
In particular, the proximal tire clamp and the distal tire clamp will engage opposite sidewalls of the tire. The piston will extend from the actuator so that the distal tire clamp will be able to engage the tire. The piston will thereby retract into the actuator such that the tire will be stretched along a central axis to allow the tire compacting apparatus to compact the tire more simply.
Once the tire has been secured by the tire gripping apparatus, the tire rotating apparatus will begin the compaction process of the tire. More specifically, the servomotor will be set in motion, such that the drive shaft will begin rotation in the desired direction. The rotation of the drive shaft will cause further rotation of the extension shaft and the proximal tire clamp. Since the distal tire clamp is kept substantially rigid and motionless, the tire will be coiled about the central axis.
These and other objects and advantages of the invention will become apparent from the following detailed description of the preferred embodiment of the adjustable insulation apparatus.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Looking now to
FIGS. 1 through 4
, the preferred embodiment for the present invention of a tire compacting apparatus
10
is illustrated. The tire compacting apparatus
10
operates to compress a tire
12
to facilitate simple removal or destruction of the tire
12
. The tire compacting apparatus
10
of the present design includes a modular frame
14
upon which a tire rotating apparatus
20
and a tire gripping apparatus
40
are attached. The frame
14
is preferably positioned on lockable wheels
16
, with the frame
14
including a proximal side
17
and a distal side
19
.
Continuing to view
FIGS. 1 through 4
, the tire rotating apparatus
20
is mounted to the proximal side
17
of the frame
14
. The tire rotating apparatus
20
preferably includes a servomotor
22
having a drive shaft
24
that is preferably connected to a drive assembly
26
that includes an extension shaft
28
and bearings
30
. The extension shaft
28
is additionally connected to a proximal tire clamp
32
, or rotatable clamp, that is used to engage the sidewalls of the tire
12
. In particular, the proximal tire clamp
32
will securely grip and even penetrate the sidewalls of the tire
12
such that the tire
12
will move only pursuant to the movement of the proximal tire clamp
32
. It should further be noted that although the preferred embodiment of the invention is a clamp or claw, other means for providing a secure and locked connection with a tire
12
, such as a hook or chain through the center of the tire, may be incorporated into the present design to securely hold and control the tire
12
.
The tire gripping apparatus
40
is additionally shown attached to the distal side
19
of the frame
14
. The tire gripping apparatus
40
includes an actuator
42
, such as a hydraulic cylinder or a pneumatic cylinder, that has a piston
48
. The position of the actuator
42
is maintained using a support brace
44
that is connected between the actuator and the distal side
19
of the frame
14
. The piston
48
is connected to a clamp rod
46
, which is slidably mounted to the distal side
19
of the frame
14
via a set of bearings
50
. The end of the clamp rod
46
opposite the actuator
42
is connected to a distal tire clamp
52
, or a static clamp, that will securely grip and even penetrate the sidewalls of the tire
12
opposite the proximal tire clamp
32
. It should further be noted that although the preferred embodiment of the tire clamp
32
is a conventional claw or clamp, other means for providing a secure and locked connection with the tire
12
, such as a hook or chain, may be incorporated into the present design. Such embodiments must simply hold and control the tire
12
in a secure fashion. Once the distal tire clamp
52
has engaged the tire
12
, the operator will be able to compress the tire
12
as desired.
In particular, in the preferred embodiment, the proximal tire clamp
32
and the distal tire clamp
52
will engage opposite sidewalls of the tire
12
. This engagement of the proximal tire clamp
32
with the tire
12
can be done in many ways. For example, the embodiment shown in
FIG. 1
illustrates the use of a pair of proximal actuators
33
, such as pneumatic or hydraulic actuators, that cooperatively open and close the clamp to engage the tire
12
. However, in
FIG. 8
, the use of a proximal screw
31
is illustrated. In any case, the proximal tire clamp
32
will engage and hold the tire
12
first. The piston
48
will then extend from the actuator
42
so that the distal tire clamp
52
will be able to engage the opposing side of the tire
12
. By incorporating the actuator
42
into the design, the user will be able to engage and hold any tire
12
, irregardless of the diameter of the tire
12
. The distal tire clamp
52
engages the tire
12
in the same manner as the proximal tire clamp
32
. In particular, a pair of distal actuators
53
(see
FIG. 1
) or distal screw
51
(see
FIG. 8
) are used to open the distal tire clamp
52
to engage the tire
12
.
Once the tire
12
has been engaged by both the proximal tire clamp
32
and the distal tire clamp
52
, the tire rotating apparatus
20
will begin the compaction process of the tire
12
. More specifically, the servomotor
22
will be set in motion, such that the drive shaft
24
will begin rotation in the desired direction. The rotation of the drive shaft
24
will cause further rotation of the extension shaft
28
and the proximal tire clamp
32
. Since the distal tire clamp
52
is kept substantially rigid and motionless, the tire
12
will be coiled about the central axis
54
, as shown in
FIGS. 2 and 3
.
Looking to
FIG. 4
, after the tire
12
has been plaited in the tire compacting apparatus
10
, the operator will have the opportunity to secure the coiled position of the tire
12
. In particular, the operator will fasten at least one locking belt
56
around the tire
12
to prevent the tire
12
from attempting to return to the original position. However, in the preferred embodiment, at least two or three belts
56
are incorporated to assure that the tire
12
remains compacted. The locking belts
56
can be any type of belt that can be secured tightly around the compressed tire
12
, including embodiments incorporating a fabric belt, a metal belt, or a rubber belt. The locking belt
56
will secure the compressed tire
12
in a substantially cylinder-shaped position, such that the compressed tire
12
is more easily transported by the operator than the conventional tire used in commerce. This shape also allows the operator to develop new ways to use the tire
12
in recycling processes and recycled items.
It should also be noted that one embodiment of the present invention allows the operator to stretch the tire
12
after the proximal tire clamp
32
and the distal tire clamp
52
have engaged the tire
12
. More specifically, once the distal tire clamp
52
has engaged the tire
12
, the piston
48
will thereby retract into the actuator
42
such that the tire
12
will be stretched along a central axis
54
, thereby altering the shape of the tire
12
from substantially circular to an ovular configuration (as shown in FIG.
2
). This ovular configuration may vary due to the construction of the tire
12
to give a uniform desired result. Although not required to compact a tire
12
, the process of stretching the tire
12
prior to compacting the tire
12
will allow the tire compacting apparatus
10
to twist and compact the tire
12
more easily.
The tire compacting apparatus
10
acts to reduce the bulkiness of a tire
12
by then twisting the tire
12
around a central axis
54
such that the outer edges of the tire
12
are brought together. When such torque is applied to the tire
12
, or any other material for that matter, a field of equal perpendicular tensile and compressive stresses is created. The tire
12
will distort (and fail with enough torque) in either tension or compression, depending upon the material's physical properties. Furthermore, this failure mode will approach a 45 degree angle with its centerline. A reinforced rubber tire
12
is much stronger in tension than in compression. As a result, it will begin to fold along a diagonal spiral line due to the compressive stresses. It is this stress that tends to squeeze all of the air from the tire
12
.
Looking now to
FIGS. 5 through 7
, a second embodiment of the invention is provided. The tire compacting apparatus
10
of this second embodiment includes a stable holding member
60
and a rotating holding member
70
, with the tire
12
being supported by both the stable holding member
60
and the rotating holding member
70
.
Looking specifically to
FIG. 5
, the stable holding member
60
includes a substantially rigid arm
62
positioned on a resolute surface
64
or beam, such as a wall or a post, and a chain
66
that is connected to the rigid arm
62
. The chain
66
therefore extends from the rigid arm
62
to engage the tire
12
. The chain
66
may loop through the tire
12
and back to the rigid arm
62
, or, looking to
FIG. 5
, a first mounting bracket
68
may be attached to each side of the tire
12
such that the chain
66
extends from the rigid arm
62
to be connected with the first mounting bracket
68
.
Continuing to view
FIG. 5
, the rotating holding member
70
of the preferred embodiment includes a servomotor
72
having a rotatable shaft
74
. A support arm
76
is connected to the rotatable shaft
74
, with the support arm
76
preferably having the shape of a hook to engage a winding chain
78
. The winding chain
78
preferably extends from the support arm
76
to traverse the center of the tire
12
and return to the support arm
76
. Similar to the first mounting bracket
68
described above, a second mounting bracket
80
may be attached to the tire
12
such that the winding chain
78
extends from the support arm
76
to be connected with the second mounting bracket
80
. Moreover, the rotating holding member
70
is preferably elevated by various means, such as by a platform
82
as shown in FIG.
5
. Consequently, when the support chain
66
and the winding chain
78
engage the tire
12
, the tire
12
will be above a ground or floor surface.
Looking to
FIGS. 6 and 7
, the second embodiment coils the tire
12
about a central axis much the same as the previous embodiment. Once the tire compacting apparatus
10
has provided the desired compaction, the user will be able to affix locking belts
56
around the edge of the tire
12
, and then disconnect the support chain
66
and the winding chain
78
from the tire
12
for disposal of the tire
12
.
Thus, although there have been described particular embodiments of the present invention of a new and useful TIRE COMPACTING APPARATUS AND METHOD OF EMPLOYING THE SAME, it is not intended that such references be construed as limitations upon the scope of this invention except as set forth in the following claims.
