Description
[0001] This is a divisional application of pending U.S. patent
application Ser. No. 11/333,659 filed Jan. 18, 2006 and now U.S.
Pub. No. 2007/0163915.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to exhibition devices, and in
particular to an exhibition device for reversal spanners, wherein
it can prevent the seat from rotating reversely and the reversal
spanner will restore by idle rotation. Thereby the spanner can
rotate bi-directionally. Thus the spanner suspending on the
suspending plate can be tested easily by the buyers. Furthermore,
the present invention can emit sound as the teeth thereof slide.
The user can determine the smoothness of the driving operation.
[0004] 2. Description of the Prior Art
[0005] Some prior arts, such as U.S. Pat. No. 6,375,005, U.S. Pat.
No. 6,409,015 and U.S. Pat. No. 6,464,840 disclose structures about
exhibition frames.
[0006] In these prior arts, when a ratchet spanner restores, a
hexagonal seat will rotate with the ratchet spanner due to the
defect in the design of the seat and the suspending plate. Thereby
the ratchet spanner loses the mechanism of idle rotation in
restoring. However this is not beneficial in test. Thus in test,
the user can only test the spanner in a predetermined direction.
The user cannot know the smoothness of the spanner as the spanner
idly rotates. Thereby the prior art is not an idle design.
SUMMARY OF THE INVENTION
[0007] Accordingly, the primary object of the present invention is
to provide an exhibition device for reversal spanners, wherein it
can prevent the seat from rotating reversely and the reversal
spanner will restore by idle rotation. Thereby the spanner can
rotate bi-directionally. Thus the spanner suspending on the
suspending plate can be tested easily by the buyers. Furthermore,
the present invention can emit sound as the teeth thereof slide.
The user can determine the smoothness of the driving operation.
[0008] To achieve above object, the present invention provides an
exhibition device for reversal spanners which comprises a
suspending plate having a buckling hole; a periphery of the
buckling hole being formed with a notch so as to form as a
confining unit; an inner side of the confining unit having a
plurality of limiting teeth; and a seat; a connecting unit
extending from the seat; the connecting unit being rotatably
buckled to the buckling hole; a ratchet portion being formed on a
surface of the connecting unit; the ratchet portion being not
aligned to the notch; and the ratchet portion being engageable to
the limiting teeth.
[0009] Furthermore, the present invention provides an exhibition
device for reversal spanners which comprises a suspending plate
having a buckling hole; a periphery of the buckling hole; a front
side has a ratchet portion at a periphery of the buckling hole; and
a seat; a connecting unit extending from the seat; the connecting
unit being rotatably buckled to the buckling hole; the seat having
a disk; a bottom of the disk having notch as a limiting unit; a
bottom of the disk being formed with teeth which are engageable to
the ratchet portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] In order that those skilled in the art can further
understand the present invention, a description will be provided in
the following in details. However, these descriptions and the
appended drawings are only used to cause those skilled in the art
to understand the objects, features, and characteristics of the
present invention, but not to be used to confine the scope and
spirit of the present invention defined in the appended claims.
[0021] Referring to FIGS. 1 to 5, an exhibition frame 1 of the
present invention has the following elements.
[0022] A suspending plate 10 has a buckling hole 11. A scale
portion 12 is formed around the buckling hole 11. A suspending hole
13 is formed above the buckling hole 11. At least one post 14 is
installed below the buckling hole 11. On one side of the buckling
hole 11 is formed with a notch 15. On a periphery of the notch 15
is formed with a long confining unit 16. On an inner side of the
confining unit 16 is formed with a plurality of teeth 161 with 45
degrees sides. Two symmetrical slits 17 are formed aside the
confining unit 16. An elastic sheet 18 is formed between the two
slits 17. On a front end (inner side) of the elastic sheet 18 is
formed as an inclined tip portion 181.
[0023] A seat 20 has a hexagonal shape. On a lower end of the seat
20 is extended with a bar-like connecting unit 21. At the
connection of the seat 20 and the connecting unit 21 is formed with
an enlarged disk 22. A triangular indication 221 extends from the
disk 22. On a lower surface of the connecting unit 21 is formed
with a cruciform slot. Thus, when the connecting unit 21 is
compressed, it will reduce inwards. Thus, the connecting unit 21
can be inserted into the buckling hole 11 and then it is buckled to
the suspending plate 10 by a buckle 23 of the seat 20 to resist
against a rear surface of the suspending plate 10.
[0024] A limiting frame 30 has a T shape connecting plate 31 and a
U shape frame plate 32. A top end of the connecting plate 31 has a
toggle 311 and a lower end thereof is transversally extended with a
plate like sealing plate 312. On a surface of the sealing plate 312
is formed with a plurality of strips 313. One side of the sealing
plate 312 is formed with a buckling hole 314 and on another side
thereof is integrally extended with a frame plate 32. One lateral
side of the frame plate 32 has a wing 321 which can be adhered to
the sealing plate 312. On a surface of the wing 32 is installed
with a buckle body 322 capable of being combined to the buckling
hole 314 so that the connecting plate 31 and the frame plate 32 are
formed with a receiving portion 33 which can be opened. Thereby a
reversal spanner 50 can be received in the two short sides of the
receiving portion 33 so as to form as a clamping sheet 34 for
clamping the reversal spanner 40. Above mentioned structure is the
structure of the present invention.
[0025] Assembly of the present invention will be described herein.
The toggle 311 at the top of the T shape connecting plate 31 is
suspended to the connecting unit 21 of the seat 20. Then the
connecting unit 21 is pressed into the buckling hole 11. The buckle
23 at the front end thereof resists against the suspending plate
10. Then a reversal spanner (in this embodiment, it is a reversal
adjustable spanner, however it can be an open end spanner or a
ratchet spanner) passes through the receiving portion 33 formed by
the connecting plate 31 and the frame plate 32. The strips 313 on
the surface of the sealing plate 312 will press and the spanner and
the elastic sheet 34 at two sides will elastically clamp the
spanner. Thereby the driving portion of the spanner 40 will be
engaged to the hexagonal seat 3. The ratchet wheel 24 at the
surface of the connecting unit 21 of the seat 20 is engaged to the
teeth 161 of the confining unit 16. Meanwhile, it is horizontally
engaged to the tip portion 181 of the elastic sheet 18.
[0026] In use, the user holds the handle of the spanner 50 to
rotate clockwise toward the post 14. The post 14 is limited not to
move forward. The spanner 50 will drive the seat 20 to rotate with
the seat 20. The ratchet portion 24 of the seat 30 will be engaged
to the teeth 161 of the confining unit 16 and the tip portion 181
at the front end of the elastic sheet 18. They will emit sound as
the teeth slide. Thereby the user can adjust the smoothness of the
driving operation.
[0027] The reason that the seat 20 can rotate along a predetermined
direction is that the seat 20 will press the confining unit 16 to
move toward the notch 15. The seat 20 will rotate by the driving
operation of the spanner 40.
[0028] On the contrary, referring to FIGS. 6 and 6A, when the
reversal spanner 50 restores along a reversal direction, it will
drive the seat 30 to rotate reversely. The seat 20 is limited by
the resisting affect of the confining unit 16 and the ratchet
portion 24 of the connecting unit 21, the ratchet 24 will be
stopped by the confining unit 16. Thereby the spanner 40 will
rotate idly for next use.
[0029] In the present invention, the suspending plate 10 is
installed with a confining unit 16 corresponding to the ratchet
portion 24 of the seat 20. It can prevent the seat 20 from rotating
reversely and the reversal spanner 40 will be restored by idle
rotation. Thereby the spanner can rotate bi-directionally. Thus the
spanner suspending on the suspending plate can be tested easily by
the users.
[0030] Referring to FIGS. 7 and 8, a second embodiment of the
present invention is illustrated. Those identical to the first
embodiment will be identified by the same numerals. Thus the
details will not be described herein.
[0031] In this embodiment, on a bottom side of the disk 22 is
formed with a notch B. A limiting unit C is formed aside the notch
B. On a bottom of the limiting unit C are formed with a plurality
of teeth D. One side of each tooth D is an inclined surface and
another side thereof is a vertical surface.
[0032] A ratchet portion A is installed at a front surface of the
suspending plate 10 and at a periphery of the buckling hole 11. The
ratchet portion A has teeth which are engageable to the limiting
teeth D. When the seat 20 is driven by a reversal spanner 40 to
rotate along a predetermined direction, the inclined sides of the
limiting teeth D will slide to make the limiting unit C rotate
toward the notch B. If the seat 20 is driven by the reversal
spanner 40 to rotate reversely, it is limited by the engagement of
the ratchet portion A at the front end surface of the suspending
plate 10 and the limiting teeth D. Thereby the seat 20 is prevented
from being driven reversely.
[0033] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the
present invention, and all such modifications as would be obvious
to one skilled in the art are intended to be included within the
scope of the following claims.
