[0001] The invention relates to a cot, particularly a nursery cot, having a drop side.
[0002] Operation of the drop sides of such cots is often such that it is usually necessary
to operate mechanism at each side manually, so that the sides often jam, and in any
event carrying out these operations while holding an infant or baby can be difficult.
[0003] It is accordingly an object of the invention to seek to mitigate these disadvantages.
[0004] According to the invention there is provided a cot having a drop side, wherein there
is a mechanism for raising and lowering the drop side comprising complementary relatively
slidable means on opposite ends of the dropside and adjacent members of the cot, and
biassing means adapted to secure the drop side in the raised position and which allows
the drop side to move to the lowered position when the bias thereof is overcome.
[0005] The relatively slidable means may comprise a groove in each of the adjacent members
and projecting spigots on the opposite ends of the drop side.
[0006] The groove may terminate in a blind slot in a plane substantially parallel to the
plane of the length of the groove.
[0007] The blind slot may be separated from the groove by an upstanding nib.
[0008] The biassing means may comprise a spring inclined towards the blind slot.
[0009] The spring may be a leaf spring inclined at about 30 to the length of the groove.
[0010] A cot embodying the invention is hereinafter described by way of example with reference
to the accompanying drawings.
[0011]
Fig. 1 is a perspective view of a nursery cot according to the invention; and
Fig. 2 is, to an enlarged scale, a side elevational view of an end rail of the cot
of Fig. 1 showing part of mechanism for allowing drop side operation.
[0012] Referring to the drawings there is shown a cot 1, having a drop side 2 , wherein
there is a mechanism 3 for raising and lowering the drop side 2 comprising complementary
relatively slidable means 4, 5 on opposite ends of the drop side 2 and adjacent members
6 of the cot, and biassing means 7 adapted to secure the drop side 2 in the raised
position and which allows the drop side 2 to move to the lowered position when the
bias thereof is overcome.
[0013] The relatively slidable means 4, 5 comprises a groove 8 in the adjacent member 6
of the cot 1, for example the ends, and projecting spigots 4 with enlarged heads (not
shown) projecting from the opposite ends of the drop side 2. The enlarged heads are
spaced from the opposite ends of the drop side 2 a sufficient distance to engage in
the respective grooves 8, and allow relative sliding motion vertically. The grooves
8 are of T-shape in cross section, the enlarged heads essentially engaging in and
sliding up and down in the "head" 9 of the "T", the shank of the "T" allowing for
passage and sliding of the spigot 4, which is of less lateral dimension then the head.
The groove 8 has an enlarged part 10 at the bottom, as viewed, for initial entry of
the head and there is mounted therein a resilient buffer (not shown). The upper (as
viewed) end of the groove 8 leads to a seat in the form of a blind slot 11, the seat
11 being displaced laterally of the plane of the length of the main body of the groove
8 from which it is separated by an upstanding nib 12 having a rounded nose or free
end. The biassing means 7 of the mechanism 3 is in the form of a spring inclined towards
the blind slot 11 from a side of the groove 8 opposite the blind slot. The spring
in the embodiment shown is in the form of a leaf spring 13, which is one leg of a
V-shaped spring the other 14 of which terminates in a hook 15 which hooks over a fixing
device such as a screw 16. The spring 7 is mounted in a pressing set in a rebate in
the body of the end member of the cot and this is covered with a metal plate 17, also
set in the rebate to be substantially flush with the face of the body facing the end
of the drop side 2, and providing the nib 12. The screw 16 is one of four screws 16,
16', 16", 16"' which hold the pressing and plate together and in position in the body
of end member 6.
[0014] The mechanism described is on a lower part of the face of the end member 6 of the
cot. Above it there is a further groove 18 which receives a projecting spigot of the
cot drop side 2, for relative sliding motion, there being a buffer (not shown) in
an enlarged lower part 19 of the groove 18. The horizontal axis of the grooves 8 is
laterally offset from, and subtantially parallel to, the longitudinal axis of the
groove 18. The axis of the groove 18 is colinear with the centre of the slot 11.
[0015] In operation with the upper spigot in the groove 18 and the spigot 4 of the mechanism
3 in the groove 8, it will be assumed that the drop side is in a lowered position.
In this position, the heads seat on the respective buffers. If it is desired to close
the cot by raising the drop side 2 to the raised position, it is merely necessary
to grip the drop side 2 say by its upper rail 20 and raise it vertically. The spigots
slide in the grooves to the top. At the top of the groove 8, the spring 13 is pushed
to the right as viewed, against its bias. It thus urges the spigot 4 to the left,
over the nib 12, and the spigot 4 on release of the drop side 2, drops into the seat
11. Alternatively, it can be lowered in manually. In either case, the spiogot 4 is
seated in the seat 11 and is held there by the spring 13, which acts as a guard to
prevent unwanted use. The drop side 2 is therefore safely and securely maintained
in the raised position. To lower the drop side 2, it is gripped, raised and at the
same time pushed by the leg or hip of the user outside the cot 1 towards the interior
of the cot so that the spigot 4 pushes the spring 13 against its bias to the right
as viewed so that the groove 8 becomes unobstrac- ted; the side 2 can then be lowered,
spigots 4 travelling down their respective grooves to rest on the buffers, which absorb
any shocks on impact.
[0016] It will be understood that respective grooves, and the seat 11 and springs 7 are
within the body of the end members 6 of the cot 1, so there are no projecting parts
which can trap fingers, snag on clothing, or be tampered with by unauthorised user.
[0017] The drop side can be manipulated with one hand in raising and lowering operations.
[0018] It will further be understood that a drop mechanism at one side only of the drop
side 2 has been described. An identitical one is provided at the opposite side.
