Abstract
A membrane reel fixing device for a membrane strapping dispenser
includes a reel pivot having its outer circumference formed
integral with three support ribs respectively connected with a
convex holding plate extending along the circumference of the reel
pivot. The three holding plates have their lower sides suspended in
midair; therefore, when pressed diametrically, the holding plates
can be elastically shifted and deformed and after a membrane reel
is fitted on the reel pivot, the holding plates can firmly prop the
inner wall of the central tube of the membrane reel.
Different-sized membrane reels can be firmly fitted on the reel
pivot by means of the holding plates that can be elastically
shifted and deformed.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a membrane reel fixing device for
a membrane strapping dispenser, particularly to one able to firmly
fix a membrane reel in position and applicable to different-sized
membrane reels.
[0003] 2. Description of the Prior Art
[0004] Generally, a membrane reel has a membrane wound thereon to
be released and strapped on articles so as to prevent them from
swaying and falling when they are stored or transported. Nowadays,
a membrane strapping dispenser is widely employed for the
convenience of carrying out membrane releasing and strapping work.
A conventional membrane strapping dispenser 10, as shown in FIG. 1,
includes a reel pivot 11 and a handle 12. The reel pivot 11 is
formed with a hollow shaft 111 having a lower end extending outward
diametrically and forming a stopping rim 112 and the outer
circumference of the other end formed with three support ribs 113
extending axially. Each support rib 113 has its upper edge
connected with a concave holding plate 114 having its rear end
connected with the stopping rim 112. After a membrane reel is
fitted on the reel pivot, the inner wall of the central tube of the
membrane reel and the opposite axial side edges 115 of holding
plates 114 can be firmly engaged with each other and fixed in
position. Thus, a user can hold the handle 12 to carry out
releasing and strapping work of membrane.
[0005] However, although the inner diameters of the central tubes
of common membrane reels are fixed and similar in size, yet there
is still a little difference between them. In addition, the holding
plates 114 assembled on the conventional membrane strapping
dispenser 10 for fixing the central tube of the membrane reel are
fixed in structure and in size, inapplicable to all central tubes
of membrane reel with similar sizes. As a result, it is always
found that the membrane reel cannot be fitted on the reel pivot or
that the membrane reel cannot be firmly fixed in position after it
is fitted on the reel pivot.
SUMMARY OF THE INVENTION
[0006] The objective of the invention is to offer a membrane reel
fixing device for a membrane-strapping dispenser, provided with a
reel pivot having its circumference formed integral with three
support ribs extending outward axially. Each support rid is
connected with a convex holding plate extending along the
circumference of the reel pivot. The three holding plates have
their lower sides opposite to a handle fitting rod suspended in
midair; therefore, when pressed diametrically, the holding plates
can be elastically shifted and deformed and after a membrane reel
is fitted on the reel pivot, the holding plates are able to firmly
press the inner wall of the central tube of the membrane reel.
Thus, different-sized membrane reels can be firmly fitted on the
reel pivot of the membrane strapping dispenser of this invention by
means of the holding plates that can be elastically shifted and
deformed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] A preferred embodiment of a membrane reel fixing device for
a membrane strapping dispenser in the present invention, as shown
in FIGS. 2, 3 and 4, includes a reel pivot 20, a handle fitting rod
30 extending axially from one end of the reel pivot 20, and a
movable handle 40 pivotally fitted on the handle fitting rod
30.
[0014] The reel pivot 20 is formed with a hollow shaft 21 having
the circumference of one end extending outward to form a stopping
annular surface 22 having one side extending outward diametrically
and forming a stopping rim 23. The hollow shaft 21 is connected
integrally with the handle fitting rod 30. The membrane 52 on the
membrane reel 50 can be released for strapping after the central
tube of the membrane reel 50 is firmly fitted on the reel pivot 20,
as shown in FIG. 5.
[0015] Further, the hollow shaft 21 of the reel pivot 20 has its
outer circumferential surface formed integral with three support
ribs 24 protruding outward and spaced apart equidistantly. Each
support rib 24 has its upper edge formed with a convex holding
plate 25 extending along the circumference of the reel pivot 20 and
having its inner intermediate portion connected with the support
rib 24. Each holding plate 25 has its upper end protruding out of
the support rib 24 so that the holding plates 25 can be elastically
pressed to move inward for facilitating fitting a membrane reel 50
on the reel pivot 20. In addition, each holding plate 25 has its
opposite outer walls respectively and axially fixed with a
tightening rib 251 protruding outward to exceed the inner diameter
of the central tube 51 of the membrane reel 50 and each tightening
rib 251 of the holding plate 25 is formed with an arc-shaped upper
edge 252 for closely pushing against the inner wall of the central
tube 51 of the membrane reel 50 fitted thereon. Each tightening
ribs 251 has its insert end formed with a guiding slope 253 for
smoothly guiding the central tube 51 of the membrane reel 50 to be
fitted on the reel pivot 20. Furthermore, the holding plates 25
have their lower sides opposite to the handle fitting rod 30
separated from the stopping rim 23 and suspended in midair. Thus,
when pressed inward diametrically, the holding plates 25 can be
elastically shifted and deformed to closely push against the inner
wall of the central tube 51 after the membrane reel 50 is fitted on
the reel pivot 20.
[0016] In using, as shown in FIG. 5, firstly, the reel pivot 20 of
the membrane strapping dispenser is inserted in the shaft hole 511
of the central tube 51 of the membrane reel 50. The inner wall of
the central tube 51 of the membrane reel 50 can be smoothly guided
and fitted on the reel pivot 20 through the guiding slopes 253 at
the front sides of the tightening ribs 251 of the holding plates
25. Since the holding plates 25 have their tightening ribs 251
protruding out a little to exceed the inner diameter of the central
tube 51 of the membrane reel 50; therefore, when the central tube
51 of the membrane reel 50 is continuously inserted inward on the
reel pivot 20, the tightening ribs 251 of the holding plates 25
will be pressed by the inner wall of the central tube 51 of the
membrane reel 50 to move bias elastically to enable the membrane
reel 50 to be smoothly fitted on the reel pivot 20. At this time,
the tightening ribs 251 of the holding plates 25, after shifted and
deformed elastically, can closely push against the inner wall of
the central tube 51 of the membrane reel 50 and firmly fix the
membrane reel 50 on the reel pivot 20.
[0017] As can be understood from the above description, the
tightening ribs 251 of the holding plates 25 of the membrane
strapping dispenser of this invention can be elastically adjusted
to move bias in accordance with different sizes of the central
tubes 51 of membrane reels 50. Therefore, the central tubes 51 of
membrane reels 50 with a little difference in size can be firmly
fitted on the reel pivot 20 of the membrane strapping dispenser for
carrying out releasing and strapping work of the membrane 52.
[0018] While the preferred embodiment of the invention has 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.
