Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates to a rotary structure for a membrane strapping apparatus, particularly to one provided with a reel pivot having one end opposite to a movable handle formed with a stopping annular surface extending downward for a preset distance to be pressed to stop a membrane reel from releasing the membrane wound thereon so that the membrane released can be pulled tight and pasted closely on the surfaces of an article, convenient in handling.
  • 2. Description of the Prior Art
  • Generally, a membrane strapping apparatus is provided with a membrane reel having a membrane wound thereon to be released and strapped on articles so as to prevent them from swaying or falling when they are stored or transported. Nowadays, a conventional simple membrane strapping apparatus is widely employed for the convenience of carrying out membrane releasing and strapping. The conventional simple membrane strapping apparatus is provided with an immovable handle having its upper end formed integral with a reel pivot. In using, a membrane reel has one end fitted and positioned on the reel pivot of the membrane strapping apparatus and then hold the handle to carry out membrane releasing and strapping. However, in a membrane releasing and strapping process, a user's hand has to be turned together with the handle, inconvenient in use and likely to cause hurt to a user's hand.
  • In view of the above-mentioned drawback, the conventional membrane strapping apparatus is provided with a movable handle to rotate relative to the reel pivot for facilitating membrane releasing. In reality, when the membrane reel rotates to carry out membrane releasing and strapping, the reel pivot sometimes has to be kept motionless so as to enable the released membrane portion to be pulled tight and pasted closely on the surfaces of an article especially when the released membrane is bypassed the corner portions of the article. However, the conventional simple membrane strapping apparatus with a movable handle is provided with no stopping device to be pressed for stopping the reel pivot from rotating by a user's hand that holds the handle. Therefore, when the user applies a force to pull tight the released membrane portion, it is impossible to keep the reel pivot motionless, unable to strap an article tightly.
    • SUMMARY OF THE INVENTION
  • The objective of the invention is to offer a rotary structure for a simple membrane strapping apparatus, provided with a reel pivot having one end opposite to a movable handle formed with a stopping annular surface extending downward for a preset distance to be pressed for stopping the reel pivot from rotating by a user's hand that holds the movable handle.
  • The stopping annular surface provided in the rotary structure of the present invention is convenient for a user to press and stop the reel pivot from rotating and synchronously stop the membrane wound on a membrane reel from released. Thus, the membrane portion released can be pulled tight and pasted closely on the peripheral sides and the corner portions of an article, greatly heightening quality and efficiency of membrane strapping operation.

  • FIG. 1 is a perspective view of a first preferred embodiment of a membrane strapping apparatus in the present invention:
  • FIG. 2 is an exploded perspective view of the first preferred embodiment of the membrane strapping apparatus in the present invention:
  • FIG. 3 is a side view of the first preferred embodiment of the membrane strapping apparatus in the present invention:
  • FIG. 4 is a side view of the first preferred embodiment of the membrane strapping apparatus in a using condition in the present invention:
  • FIG. 5 is a perspective view of a second preferred embodiment of a membrane strapping apparatus in the present invention: and
  • FIG. 6 is a side view of the second preferred embodiment of the membrane strapping apparatus in a using condition in the present invention.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • A first preferred embodiment of a rotary structure for a simple membrane strapping apparatus 10 in the present invention, as shown in FIGS. 1, 2 and 3, includes a reel pivot 20, a handle-fitting rod 30, a movable handle 40 and a membrane reel 50. The reel pivot 20 is column-shaped with a comparatively large diameter for fitting and positioning the membrane reel 50 thereon, having one end axially extending downward and forming the handle fitting rod 30 with a comparatively small diameter. The movable handle 40 is pivotally fitted on the handle fitting rod 30, able to rotate relative to the reel pivot 20 and the membrane reel 50 so as to let the membrane reel 50 release the membrane 51 wound thereon for carrying out membrane strapping.
  • Further, the reel pivot 20 has its lower side formed with a bottom rim 21 having a portion near its center axially extending downward for a preset distance and forming an annular wall 22, which has its outer circumferential side provided axially with a plurality of stopping ribs 231 surrounding all sides. The stopping ribs 231 have their upper ends extending to reach a region near the center of the bottom rim 21 of the reel pivot 20 and forming a stopping annular surface 23 to be pressed stopping the reel pivot 20 from rotating by a user's hand that holds the movable handle 40.
  • In assembling and using, as shown in FIG. 4, firstly, the membrane reel 50 has a shaft hole 52 in one end fitted with the reel pivot 20 of a membrane strapping apparatus 10 to position the membrane reel 50 thereon. Next, a user holds the movable handle 40 of the membrane strapping apparatus 10 with one hand and pull outward the membrane 51 on the membrane reel 50 for a short distance with the other hand and paste it on one peripheral side of an article and have it bypassing a nearby corner portion of the article and fix it thereon. Subsequently, the membrane strapping apparatus 10 is held and moved along the peripheral sides of the article (a large-sized one able to be placed at a certain position) and synchronously the reel pivot 20 of the membrane strapping apparatus 10 will automatically rotate and actuate the membrane reel 50 to rotate and release the membrane 51. To ensure the membrane 51 pulled outward to be closely strapped on the surfaces of an article, simply press the strapping ribs 231 on the stopping annular surface 23 under the reel pivot 20 to stop the reel pivot 20 from rotating with the thumb of one hand that holds the movable handle 40 before the membrane 51 is bypassed the boundary of each corner portion of the article. At this time, when the membrane strapping apparatus 10 is held to move forward again, the previously released membrane 51 can be pulled tight and pasted closely on the peripheral surfaces and another corner portion of the article.
  • A second preferred embodiment of a rotary structure for a membrane strapping apparatus 10 in the present invention, as shown in FIGS. 5 and 6, is almost the same as that described in the first preferred embodiment, except that the membrane strapping apparatus is provided with a column-shaped reel pivot 20′ with a comparatively small diameter, and the reel pivot 20′ has its circumferential surface provided with four strip-shaped positioning ribs 24 and its lower side formed with an annular member 25 with a diameter larger than that of a handle fitting rod 30. The annular member 25 has its bottom rim 21 provided thereon with a plurality of stopping ribs 231 extending upward. Thus, the membrane reel 50 can easily be fitted on the reel pivot 20′, which can be controlled to stop rotating as described in the first preferred embodiment.
  • Evidently, this invention has the following advantages.
  • L. In a membrane releasing and strapping process, the stopping annular surface 23 formed at the lower end of the reel pivot 20, 20′ can be timely pressed by a user's hand that holds the movable handle 40 to stop the membrane 51 from released so as to enable the released membrane 51 to be pulled tight and pasted closely on the surfaces of an article, achieving an excellent effect of membrane strapping operation.
  • 2. To stop the reel pivot 20 from rotating and the membrane 51 from keeping released, it is enough only to press the stopping annular surface 23 with the thumb of a user's hand that holds the movable handle 40, easy and quick in handling.
  • 3. The stopping annular surface 23 is simple in structure, easy to be produced and very profitable.
  • While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
