Description
COUPLING DEVICE
This invention relates to a coupling device which is suitable for coupling plates together.
Japanese Utility Model Public Disclosure No. SHO 56-67411 discloses a device for securing together two plates in an overlapped state. This device comprises a first fastener of a plastic material having a head portion and a shaft portion depending from the lower surface of the head portion and a second fastener of a plastic material having a flange portion facing the head portion of the first fastener and a cylindrical portion extending from the top of the flange portion and permitting the insertion of the shaft portion of the first fastener and is provided with locking means disposed one on the outer periphery of the shaft portion of the first fastener and the other on the inner periphery of the cylindrical portion of the second fastener.
In this prior art securing device, the locking means consists of annular stepped locking surfaces formed on the outer periphery of the shaft portion of the first fastener and the inner periphery of the cylindrical portion of the second fastener and adapted to engage with each other. The two stepped locking surfaces are engaged with each other by inserting the shaft portion of the first fastener into the cylindrical portion of the second fastener, thus locking the shaft portion of the first fastener in the cylindrical portion of the second fastener such that it cannot be detached.
With the aforementioned prior art securing device, however, the distance between the head portion of the first fastener and the flange portion of the second fastener is determined by the positions of the stepped locking surfaces of the two fasteners. Therefore, if the sum of the thicknesses of the plates to be secured together is different from the distance between the head portion and the flange portion of the two fasteners, the two fasteners cannot be secured to each other or, if they can be secured to each other, cannot be firmly coupled to each other.
Further, since the two stepped locking surfaces are locked to each other such that one of them cannot be detached from the other, once the two fasteners are coupled together, the two cannot be readily detached from each other.
This invention aims at solving the above problems, and for this purpose provides a coupling device which can secure two or more plates firmly irrespective of variation in the sum of the thicknesses of the plates to be secured together and also permits ready coupling and detachment of the two fasteners.
According to the invention, there is provided a coupling device, for coupling plates together,which comprises locking means consisting of two parts provided on the outer periphery of a shaft portion of a first fastener and the inner periphery of a cylindrical portion of a second fastener and capable of being engaged with each
other, the locking means including of a helical groove
formed in the outer periphery bf the shaft portion of the resilient
first fastener and at leas dportion pro3ecting from the inner periphery of the cylindrical portion of the second
fastener in the direction of insertion of the shaft
portion obliquely inwardly such that a free end of said
at least one resilient portion can fit in said helical groove.
To couple together two plates with this
device, the two plates are formed with respective
through-holes, and the two through-holes are aligned by
overlapping the two plates.
Then, the shaft portion of the first fastener
and cylindrical portion of the second fastener are
inserted in a face-to-face relation through the through
holes from the opposite sides.
As a result, the shaft portion of the first
fastener is projected into the cylindrical portion of the
second fastener in the aligned through-holes. At this time, the /resilient(Ulastic)portions in the cylindrical portion project obliquely inwardly. Thus, when the shaft portion
proceeds through the cylindrical portion, the elastic
portions are pushed and flexed radially outwardly.
In this way, the shaft portion of the first
fastener advances into the cylindrical portion of the
second fastener. When the lower surface of a head
portion makes contact with the upper surface of the first
plate, the first fastener can no longer be pushed. Thus,
by stopping the pushing of the first fastener, the
elastic portions in the cylindrical portion of the second
fastener are closed radially inwardly by the elastic
restoring force, and their ends (teeth) are fitted in the
helical groove of the shaft portion, thus retaining the
shaft portion in the cylindrical portion such that it
cannot be detached.
Thus, the two plates can be clamped between the lower surface of the head portion of the first fastener and upper surface of a flange. portion of the second fastener and are coupled together in an overlapped state.
In this state, by screwing the first fastener the shaft portion is advanced further deeply into the cylindrical portion, and the coupling force between the two plates is increased.
Conversely, when the first fastener is loosened, the shaft portion is retractedthrough the cylindrical portion, and the two fasteners are detached from each other.
One embodiment of the invention will be described in detail below with reference to the drawings in which:
Figure 1 is a sectional view showing one embodiment of the coupling device according to the invention securing together two plates in an overlapped state;
Figure 2 is a perspective view showing first and second fasteners of the coupling device shown in Figure 1 in a detached state;
Figure 3 is a side view showing the first and second fasteners in a detached state; and
Figures 4 to 6 are side views, partly in section, for explaining the procedure of securing together two plates with the coupling device according to the invention.
The drawings illustrate an embodiment of the device for coupling together two plates according to the invention. This coupling device 1 comprises a first fastener 4 having a head portion 2 and a shaft portion 3 depending from the lower surface of the head portion 2 and a second fastener 7 having a flange portion 5 facing the head portion 2 of the first fastener 4 and a cylindrical portion 6 extending from the top surface of
the flange portion 5 and permitting the insertion of the shaft portion 3 of the first fastener 4. The two fasteners 4 and 7 are one-piece moldings made of a resin, e.g., nylon, having adequate rigidity and elasticity.
As shown in Figure 4, the head portion 2 of the first fastener 4 has a cross groove 8 formed at the top, and a dish-like contact portion 9 extending from its outer periphery and adapted to make elastic contact with the top of a plate. The outer periphery of the shaft portion 3 is formed with at least one helical turn
(three in the illustrated embodiment) disposed as groove 10 in the axial direction. The thread 11 defining the helical groove 10 is saw-tooth-like in sectional profile.
Specifically, it has a tapered surface 12 on the front side in the direction of advance of the shaft portion 3 and an engagement surface 13 on the rear side in the direction of the advance.
The second fastener 7 has the annular flange portion and the cylindrical portion 6, which extends from the edge of an opening in the flange portion 5. The peripheral wall of the cylindrical portion 6 has a pair of U-shaped notches 14 each defining an elastic portion 15 extending aslant downwardly. The free ends of the elastic portions 15 are formed as segments of a helix to be fitted in the helical groove 10 of the shaft portion 3 of the first fastener 4, thus forming the teeth 16 in a vertically staggered fashion. As shown in Figure 4, the outer periphery of the end of the cylindrical portion 6 has a pair of pawls 17 projecting such that they have a saw-tooth-like sectional profile. The pawls 17 are 90degrees out of phase from the elastic portions 15.
The method of coupling together two plates B1 and B2 in an overlapped state by using the two fasteners 4 and 7 will now be described. As shown in Figure 4, the upper first plate B1 is formed with a through-hole 18 having an inner diameter which is greater than the outer diameter of the end of the cylindrical portion 6,
including the two pawls 17, of the second fastener 7.
The lower second plate B2 is formed with a through-hole
19 having an inner diameter substantially equal to the
outer periphery of the cylindrical portion 6, not
including the two pawls 17, of the second fastener 7.
The thickness of the second plate B2 is substantially equal to the distance between the top surface of the flange portion 5 of the second fastener 7 and the lower end of the two pawls 17.
Now, as shown in Figure 4, the cylindrical portion 6 of the second fastener 7 is upwardly inserted with its free end facing the through-hole 19 of the second plate B2.
When the cylindrical portion 6 of the second fastener 7 has been fully inserted, its pawls 17 engage with the edge of the through-hole 19 of the second plate
B2. Since the outer diameter of the free end of the second fastener 7 is greater than the inner diameter of the through-hole 19 of the second plate B21 the two pawls 17 are inwardly flexed by being pushed against the edge of the through-hole 19, and in this state the second fastener 7 is advanced through the through-hole 19. When the two pawls 17 clear the through-hole 19, they snap outwardly to their initial state because of the elastic restoring force of the entire cylindrical portion 6, and their lower surfaces hook on the upper edge of the through-hole 19 to clamp the second plate B2 in cooperation with the top surface of the flange portion 5
(Figure 5).In this way, the second fastener 7 is temporarily secured in the through-hole 19 of the second plate B2.
After the second fastener 7 has been temporarily secured to the second plate B2 in the above way, the first plate B1 is placed over the second plate B2, and the two through-holes 18 and 19 are aligned with respect to each other.
Then, since the second fastener 7 is temporarily secured, the shaft portion 3 of the first fastener 4 may be downwardly inserted with its free end facing the through hole 18 of the first plate B1 as shown in Figure 5.
By this insertion, the shaft portion 3 of the first fastener 4 enters the cylindrical portion 6 of the second fastener in the aligned through-holes 18 and 19 and comes in contact with the elastic portions 15.
When the first fastener 4 is strongly pushed, the teeth 16 at the end of the elastic portions 15 are pushed by the tapered surfaces 12 of the thread 11 on the shaft portion 3 of the first fastener 4, so that they are radially outwardly flexed from their stems.
After the teeth 16 of the two elastic portions 15 have passed over the tapered surface 12 of the thread 11 of the shaft portion 3, the two elastic portions 15 close radially inwardly because of their elastic restoring forces, so that the teeth 16 fall into the helical groove 10.
The elastic portions 15 are opened when the teeth 16 collide against the thread 11 and closed when the teeth 16 fall into the helical groove 10, and thus they are repeatedly opened and closed as they advance along the shaft portion 3 of the first fastener 4. The operator senses the repeated opening and closing as a series of clicks.
When the lower surface of the head portion 2 of the first fastener 4 has been brought into contact with the top surface of the first plate B1, the first fastener 4 can no longer be pushed. Thus, the pushing of the first fastener 4 is stopped. As a result, the teeth 16 fall into the helical groove 10 (Figure 1) by the elastic restoring force against the force with which the two elastic portions 15 are opened radially outwardly.
Thus, the lower ends of the teeth 16 strike the engagement surface 13 of the thread 11 so that the shaft portion 3 of the first fastener 4 is locked in the cylindrical portion 6 of the second fastener 7 such that it cannot be detached accidentally.
For this reason, as shown in Figures 1 and 6, the plates B1 and B2 are coupled together in an overlapped state as clamped between the lower surface of the contact portion 9 of the first fastener 4 and the upper surface of the flange portion 5 of the second fastener 7.
In this state, by turning the first fastener 4 in the clockwise direction with a screw driver (not shown) inserted in the cross groove 8 formed in the top surface of the head portion 2, the shaft portion 3 is advanced into the cylindrical portion 6 by screw action, thus gradually reducing the distance between the lower surface of the head portion 2 of the first fastener 4 and the upper surface of the flange portion 5 of the second fastener 7. At the same time, the disk-like contact portion 9 of the head portion 2 of the first fastener 4 is pushed against the top surface of the first plate B1 and flattened. Thus, the two plates B1 and B2 are more firmly secured by the elastic restoring force of the disk-like contact portion 9.
Conversely, when the first fastener 4 is turned in the counterclockwise directipn, the shaft portion 3 advances through the cylindrical portion 6 in the opposite direction. Eventually, the shaft portion 3 of the first fastener 4 will escape from the cylindrical portion 6 of the second fastener 7, thus releasing the coupling between the two fasteners 4 and 7 (Figure 5).
Thus the device according to this invention is particularly advantageous where it is desired to test couple the two plates B1 and B2 in overlapping state before subjecting them to some kind of required processing. Namely, the two plates can first be test coupled by coupling the two fasteners 4 and 7 and then be detached with ease by extracting the first fastener 4 from the second fastener 7 attached to the plate B2.
Then after the required processing is completed the two plates can be permanently coupled using the same first and second fasteners 4 and 7. Further, the two fasteners 4 and 7 can be easily detached as required for maintenance.
Further, when the two fasteners 4 and 7 are detached, the second fastener 7 is detached in the state of being mounted in the second plate B2 as shown in
Figure 5. Thus, there is no possibility of losing the second fastener 7, and the two fasteners 4 and 7 can be easily coupled together again.
Further, both the fasteners 4 and 7 can be readily removed, so that they may be provisionally coupled after their manufacture. When the fasteners are coupled in this way, they can be stored together and easily handled.
In the illustrated embodiment, the inner periphery of the cylindrical portion 6 of the second fastener 7 is provided with a pair of elastic portions 15 facing each other. However, one of these elastic portions may be replaced with a rigid portion, or it is possible to provide a greater number of elastic portions.
As has been described in the foregoing, according to the invention the distance between a head portion of the first fastener and flange portion of the second fastener may be freely adjusted, so that it is possible to provide a simple device for coupling together plates which enables coupling and detachment of the two fasteners and which can firmly couple together the two plates even if there is a variation in plate thickness and/or fluctuation in the quality of the two fasteners.
