Bookcover and Reading Light Assembly
This invention relates to a bookcover and reading light assembly.
According to a first aspect of the present invention there is provided a bookcover and reading light assembly wherein the bookcover can be mounted on and removed from a book and wherein the reading light is an extendible/retractable reading light integrated with the bookcover, the light having a stem which, when the light is in a retracted position, is accommodated in a housing on a spine of the bookcover.
Preferably, the light is held captive relative to the housing.
Advantageously, the housing has two compartments, one for housing batteries for energising the light and the other for accommodating the stem of the light when the latter is in a retracted position.
Preferably, the stem has one or more bendable and/or twistable sections and is able to retain a set position.
Conveniently, the assembly further comprises switching means for automatically energising and de-energising the light as it is extended and retracted, respectively.
According to a second aspect of the invention there is provided a bookcover and reading light assembly wherein the bookcover can be mounted on and removed from a book, and has a housing on a spine thereof for housing batteries, and wherein the reading light is swivellably connected to the housing for movement between extended and retracted positions.
The invention thus provides a light for night time reading which will not disturb the reader's spouse or fellow aircraft travellers. It at the same time provides privacy, if required, as to the title of the book being read and is both compact and portable.
The invention will now be more particularly described, by way of example, with reference to the accompanying drawings in which:-
Figure 1 is a developed view of the inside of one embodiment of a bookcover and reading light assembly according to the invention with the reading light partly extended. Figure 2 is a sectional view taken through the bookcover with the reading light shown in a retracted position in which the stem of the reading light is accommodated in a housing integral with the spine of the bookcover,
Figure 3 is an end view of the bookcover and reading light assembly shown mounted on a book and opened out, parts of the housing being removed to show the inside thereof and the stem of the light being shown in section.
Figure 4 is a fragmentary perspective view illustrating the bookcover mounted on a book and the stem of the reading light in a retracted position.
Figure 5 is a fragmentary view showing the housing in section with the stem of the reading light partially extended, and
Figure 6 is a perspective view of another embodiment of a bookcover and reading light assembly according to the invention, shown mounted on a book.
Referring now to Figures 1 to 5 of the drawings, the bookcover and reading light assembly shown therein comprises a flexible cover 10 which could be of plastics material , e . g . polyvinyl chlor ide , and which has a spine 11 , f ront and back leaves 12 and 13 respectively , and pockets 14 and 15 in the leaves 12 and 13 , respectively , which pock ets enable the bookcover to be removably placed on a book 9 ( see
F igures 3 and 4 ) .
The front and back leave? may have a scored or corrugated portion 16 which allows the cover 10 to fold more easily and accommodate books of different thicknesses. I f corrugated, portion 16 may be stretchable to fit books of different sizes.
A rigid or semi-rigid hous ing 17 is secured to or integrally formed with the spine 11 of the cover . This housing 17 def ines a compartment 18a_ which accommodates one or more batter ies 24 and a compartment 18b_ which accommodates a stem 19 of a reading light . The compartments 18a_ and 18_b are separated by a partition wall 25 and the compartment 18j is closed at the top and has an openable door 27 at the bottom for changing the batteries . The stem 19 is telescopically extendible f rom and retractable into the compartment 18b_ and has a stop member 20 which holds the stem captive with respect to the housing 17 by co-operation with a collar 28 f ixed to the top of the compartment 18b_. The stem 19 also has one or more bendable and/or twistable sections 21 , and a head 22 accommodating a ref lector and a replaceable light bulb 23 which is connected to the batteries by wires 26 extending through the stem 19. The head 22 is pivotably connected to the stem 19 by a collar 29.
The bendable and/or twistable sections 21 allow the head 22 of the light to be set in a desired position, the sections 21 being so designed that the head 22 can retain its set position.
The head 22 is shaped to conform with the cross-sectional shape of the housing 17 so that when the light is rectracted the head 22 extends across and conforms with the open end of the housing 17 to close the latter as shown best in Figure 4.
Moreover, as shown the housing 17 is shorter than the spine 11 to define a space for receiving the head 22 when the light is retracted. Thus the light is compactly stored when not in use.
The light may be automatically energised as it is extended from the compartment 18b_ and automatically de-energised as it is retracted into the compartment 18b_. This can be achieved by . an appropriate mechanical arrangement which ensures that electrical contacts are made as the light is extended and broken as the light is retracted. In the embodiment shown the battery compartment 18_a includes a metal contact 30 mounted (see Figure 5) at its upper end, which extends into compartment 18b_ and includes one end 30a. for contact with batteries 24 and a second end 30b_ for contact with stem 19, in a manner to be explained. In addition, compartment 18b_ includes an elongate L-shaped metal contact 31 disposed therein which has one end 31a_ connected to the lower end of batteries 24 and an upper end 31]D for contact with stem 19, in a manner to be explained. Wires 26 connected to the light bulb 23 are connected to metal contacts 32 and 33 mounted on stop member 20. As the stem 19 moves in and out relative to compartment 18b_, metal contact 33 always remains in contact with metal contact 31. Thus, it is only when metal contact 32 is brought into contact with metal contact 30b_ that the electrical circuit is completed and operates to turn the on light bulb 23. This occurs when the stem 19 is moved in an upward direction within compartment 36 to its extended position.
Alternatively the light may be provided with a manually operable on/off switch on the head 22 or on the outside of the housing 17. A page mark (not shown) may be connected to the bookcover. This page mark could be, for example, in the form of a ribbon which could have a fresnel-screen magnifier attached thereto.
Turning now to Figure 6, the bookcover and reading light assembly shown comprises an elongate battery housing 117 mounted on the spine 111 of the bookcover for housing the batteries. In this embodiment, a supporting arm 119 of the light is pivotally mounted at 140 on the outside of housing 117 and includes a reflector housing 122 and a light bulb 123. In addition, in order to adjust the direction of light, there is a pivot connection 142 between reflector housing 122 and the supporting arm 119. In this embodiment, electrical contact with the batteries within housing 117 is made by electrical wires extending from the battery housing 117 through the arm 119 and connected to light bulb 123.
The above embodiments are given by way of example only and many modifications will be apparent to persons skilled in the art without departing from the scope of the invention defined by the appended claims.
