Description

A LOCKING DEVICE
The invention relates to a locking device for use with a tap, a tap including such a locking device and a urine drainage bag including a tap including such a locking device.
Taps are used in a wide variety of applications, and in some of them, a problem which has been experienced with taps of known design is that whilst it is necessary to provide some form of handle which is easy for the user to grip and operate, such handles generally protrude some distance from the body of the tap itself, making inadvertent operation a possibility. One area where this problem is particularly acute is that of urine drainage apparatus, where a patient who is catheterised has a drainage bag for collection of urine, which is provided with a tap to enable it to be easily emptied. The tap is customarily connected to the bag in a length of tubing close to the person's body and this can give rise to problems of inadvertent operation in the case where the tap has a projecting lever arm.
A number of solutions have been suggested to this problem, for example taps including devices whereby the lever arm remains close to the adjacent tubing in both the open and closed positions, such as lost motion devices. However these do not fully solve the problem. It is an object of the present invention to seek to mitigate problems such as this.
According to a first aspect of the invention there is provided a locking device for a tap, the device comprising means to limit the extent of travel of an operating member of the tap. The device may comprise a body adapted to engage the tap, the limiting means comprising a part of the body. This provides a relatively simple solution to the problem which is inexpensive to manufacture and easy to manipulate in practice.
The device may be moveable from a limiting position to a non-limiting position whilst remaining engaged with the tap. This obviates the problem of loss of the device when it is not in use in the limiting position.
The body may include a cutaway adapted to cooperate with an inlet and/or outlet of the tap to maintain the device in engagement with the tap. The cutaway may include means to maintain the device in engagement with the tap in a non-limiting position.
According to a second aspect of the invention there is provided a tap including apparatus as hereinabove defined.
According to a third aspect of the invention there is provided a urine drainage bag including a tap including a locking device as hereinabove defined.
The invention will be further illustrated with reference to the accompanying drawings in which:
Figure 1 is a perspective view of a device according to the invention;
Figure 2 is a perspective view of a device according to the invention being fitted to a tap; Figure 3 is a perspective view of a device according to the invention in place on a tap in a limiting position; and
Figure 4 is a perspective view of a device according to the invention in place on a tap in a non-limiting position.
Referring to the drawings there is illustrated a locking device 1 for a tap 2, the device 1 comprising means 3 to limit the extent of travel of an operating member 4 of the tap 2.
In the illustrated embodiment the tap concerned is an inline tap of well known design, however the invention is equally applicable, suitably modified to other types of tap. Referring to Figure 1, the device 1 comprises a body 5 which is generally cup-shaped and includes two cut-outs 6,7 each of which extends from the rim 8 of the cup to a point just adjacent its base, such that the rim 8 is divided into two portions, 8a and 8b. As shown in Figure 1, the lower (as viewed) rim portion 8b extends beyond the upper rim portion 8a.
Cut-outs 6 and 7 are dimensioned and shaped to receive the inlet 9 and outlet 10 of the tap 2 such that the walls 11,12 of each cut-out fit in close relation thereto. The walls 11,12 of the cut-outs 6,7 are not uniform, but instead each wall is formed with two projections 13 or narrowings. In a pair of opposing walls 11,12 the projections or narrowings 13 are formed opposite one another so that the walls 11,12 and projections 13 define an entry part 14 a first seat 14a and a second seat 14b.
In use, the locking device 1 is first fitted to a tap 2 by sliding so that the inlet 9 and outlet 10 pass into the cut-outs 6,7 to the entry part 14. In order for the locking device to slide further onto the tap 2 the inlet 9 and outlet 10 must pass between the first set of projections 13 which is made possible by the resilience of the materials from which the tap and locking device 1 are formed. Having passed the first set of projections 13 the inlet 9 and outlet 10 come to rest in the first seat 14a. Further sliding the locking device 1 over the tap causes the inlet 9 and outlet 10 to pass into the second seat 14b. Thus, as illustrated in Figure 3 the walls 11,12 of the cut-outs prevent rotation of the lever 4 of the tap 1 and the tap is thus locked. In order to operate the tap without removing the locking device 1 therefrom the device is slid in the opposition direction so that the inlet 9 and outlet 10 come to rest in the first seat 14a. The locking device 1 is retained in engagement with the tap by virtue of the dimensions of the cut-outs 6,7 and the projections 13, however in this position the lever 4 of the tap can be rotated by 180° because of the difference in extent of the rim portions 8a and 8b.
