Reel structure for marine fabric tape

A reel structure for a marine fabric tape includes a reel device pivoted to an engaging seat. When a handle of a windlass is turned, a flat rod will be driven to rotate a gear shaft which then drives a gear disc to rotate. Because a head portion is positioned in an axle shaft, a fabric tape is rolled up along with the axle shaft to form a circular shape, providing an even applied force for rolling up the fabric tape.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a reel structure for a marine fabric tape, and more particularly to one having a head portion in a water drop shape of the fabric tap to be positioned in an axle shaft of a gear tray for rolling up the fabric tap along with the axle shaft, providing an even applied force.

2. Description of the Prior Art

As shown inFIG. 5andFIG. 5-A, a conventional reel structure for a marine fabric tape comprises a gear tray31′ having a central axle shaft311′ and an axle bolt313′ which is located apart from the axle shaft311′. The axle bolt313′ is inserted through the gear tray31′ and a head portion A1of a fabric tape A. The head portion A1is in a water drop shape. With a handle of a windlass to turn the axle shaft, the gear tray31′ is driven to rotate. Because the head portion A1of the fabric tape A is positioned on the axle bolt313′, the fabric tape A first wraps the axle shaft311′ and then the axle bolt313′ repeatedly to be in the from of a cam. This structure causes an uneven applied force and its operation is not smooth when the user turns the handle of the windlass. In addition, this structure bears different stress points, which may result in damage and looseness to short its service life.

SUMMARY OF THE INVENTION

According to the present invention, there is provided a reel structure for a marine fabric tape comprising an engaging seat and a reel device which is pivotally connected to the engaging seat; the engaging seat comprising a base, a stop plate, a positioning bolt, and a straight torsion spring, the base having two side boards formed with a pair of axle holes and a pair of rotation holes, one of the two side boards being formed with an aperture which is disposed in front of the rotation hole, the positioning bolt being inserted through a positioning hole of the stop plate and the aperture to be secured inside the engaging seat, the straight torsion spring being mounted on a lower portion of the stop plate, the stop plate having a stop portion; the reel device comprising a gear tray and a gear shaft, the gear tray including an axle shaft, a gear disc and an axle bolt, the axle bolt being inserted through a central pivotal hole of the gear tray and the pair of axle holes so that the gear tray being positioned between the pair of axle holes, the axle shaft being formed with a slot interconnected with the pivotal hole for insertion of a head portion of a fabric tape, the gear disc being disposed on the gear tray and located adjacent to the side board formed with the aperture to mesh with teeth of the gear shaft, the stop portion of the stop plate being adapted to engage with the teeth of the gear shaft, the gear shaft having two ends provided with left and right sleeves, a pad ring being provided on the gear shaft between the pair of rotation hole, the gear shaft being provided with a flat rod extending from the end which is located close to the aperture, the other end of the gear shaft being formed with a groove for insertion of a C-shaped ring to position the pad ring in place for rolling up the fabric tape evenly.

The head portion of the fabric tap is inserted through the slot into the pivotal hole, and the axle bolt is inserted through one of the pair of axle holes of the base, the pivotal hole of the gear tray, the head portion, and the other axle hole in sequence so that the gear tray is connected to the base. The gear disc meshes with the teeth of the gear shaft. The stop plate is urged by the straight torsion spring such that the stop portion engages with the teeth of the gear shaft to prevent a reverse rotation. When the handle of the windlass is rotated, the flat rod will be driven to rotate the gear shaft which then drives the gear disc tray to rotate. Because the head portion is positioned in the axle shaft, the fabric tape is rolled up along with the axle shaft to from a circular shape. The user can roll up the fabric tape repeatedly with the same force. The axle shaft functions as an axle center to roll up or to release the fabric tape in the form of a circle, thus its structure bears the same stress direction. It is not easy to have breakdown points in different directions which may cause looseness or damage. The present invention provides a longer service life.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown inFIGS. 1 and 2, the present invention comprises an engaging seat2and a reel device3which is pivotally connected to the engaging seat2.

The engaging seat2comprises a base21, a stop plate22, a positioning bolt23, and a straight torsion spring24. The base21has two side boards formed with a pair of axle holes211and a pair of rotation holes212. One of the two side boards is formed with an aperture213which is disposed in front of the relative rotation hole212. The positioning bolt23is inserted through a positioning hole221of the stop plate22and the aperture213to be secured inside the engaging seat2. The straight torsion spring24is mounted on a lower portion of the stop plate22for a stop portion222of the stop plate22to engage with teeth of a gear shaft32so as to prevent disengagement due to a reverse rotation, providing a smooth operation to roll up the fabric tape.

The reel device3comprises a gear tray31and the gear shaft32. The gear tray31includes an axle shaft311, a gear disc312and an axle bolt313. The axle bolt313is inserted through a central pivotal hole3111of the gear tray31and the pair of axle hole212so that the gear tray31is positioned between the pair of axle holes211. The axle shaft311is formed with a slot3112interconnected with the pivotal hole3111for insertion of the head portion A1of the fabric tape A. The head portion A1is in a water drop shape. The gear disc312is disposed on the gear tray31and located adjacent to the side board formed with the aperture213to mesh with the teeth of the gear shaft32. The gear shaft32has two ends provided with left and right sleeves324. A pad ring325is provided on the gear shaft32between the pair of rotation hole212. The gear shaft32is provided with a flat rod321extending from the end which is located close to the aperture213. The flat rod321is adapted to engage with a handle of a windlass. The other end of the gear shaft32is formed with a groove322for insertion of a C-shaped ring323so as to position the pad ring325in place for rolling up the fabric tape A evenly.

Referring toFIGS. 3-A-B,FIG. 4,FIG. 4-A, the head portion A1of the fabric tap A is inserted through the slot3112into the pivotal hole3111, and the axle bolt313is inserted through one of the pair of axle holes211of the base21, the pivotal hole3111of the gear tray31, the head portion A1, and the other axle hole211in sequence so that the gear tray31is connected to the base21. The gear disc312meshes with the teeth of the gear shaft32. The stop plate22is urged by the straight torsion spring24such that the stop portion222engages with the teeth of the gear shaft32to prevent a reverse rotation. When the handle of the windlass is turned, the flat rod321will be driven to rotate the gear shaft32which then drives the gear disc tray31to rotate. Because the head portion A1is positioned in the axle shaft311, the fabric tape A is rolled up along with the axle shaft311to from a circular shape, as shown inFIG. 4andFIG. 4-A. The user can roll up the fabric tape A repeatedly with the same force. The axle shaft311functions as an axle center to roll up or to release the fabric tape A in the form of a circle, thus the structure bears the same stress direction. It is not easy to have breakdown points in different directions which may cause looseness or damage. The present invention provides a longer service life.

Accordingly, the present invention has the axle shaft311of the gear tray31as an axle center to roll up or to release the fabric tape A evenly for its structure to bear the same stress.
