Description

PHOTOGRAPHIC BOOTHS The present invention relates to photographic booths.

Photographic booths are located at various public locations such as train stations and shopping arcades for the customer to have passport sized photographs taken. Such booths consist generally of a rectangular chamber having two side walls and two ends walls. Mounted externally of on end wall is the housing of an operating system. The operating system comprises a coin operated photographic system which is capable of taking photographs, developing them and then dispensing them in response to the input of the required value of coins. Mounted on the opposite end wall are a series of curtains which can be drawn to provide different backgrounds. In the centre of the chamber is a rigid stool which can be raised and lowered as required by the customer. Access to the booth can be gained through an opening in one side wall of the chamber. A half curtain can be drawn across the opening for privacy.

A major disadvantage of the booth is that it cannot be readily accessed by disabled people particularly those confined to a wheelchair. Also, the privacy provided by the half curtain is fairly minimal.

It is an object of the present invention to provide an improved photobooth.

According to the present invention there is provided a photographic booth comprising a chamber to be occupied by the user and having photographic apparatus directed into the chamber on one side thereof and an opening providing access to the user on the opposite side thereof.

According to the present invention there is further provided a photographic booth comprising a part circular chamber to be occupied by the user and having photographic apparatus directed into the chamber on one side thereof, an opening in the circular wall of the chamber which is opened and closed by an arcuate sliding door.

A photographic booth embodying the present invention will now be described, by way of example, with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a perspective view of a photobooth with the door partially open; Figure 2 is a side elevation of the photobooth with the door closed; Figure 3 is a plan view of the photobooth with the roof removed and showing the booth occupied by a person in a wheelchair; Figure 4 is an exploded view of the door and its support mechanism; Figure 5 is a section through a support rail and carriage of the support mechanism of Figure 4; Figure 6 is a fragmentary section through the lower part of the chamber of the booth; Figure 7 is a side elevation of the door drive mechanism; Figure 8 is a front elevation of the door and its associated detectors; and Figure 9 is a graph of speed versus distance for the door.

As shown in Figure 1, the photobooth includes an upright housing 2 generally rectangular in horizontal cross-section coupled to the upright chamber 4 generally circular in horizontal cross-section. The chamber 4 has an arcuate opening in a side thereof remote from the housing 2 which opening is closable by a sliding arcuate door 6. An elongate window 8 is provided on opposite sides of the chamber 4. Each window 8 may be covered on the inside by a blind or curtain (not shown). Located inside the chamber 4 is a fold-down seat 8 (see Figure 3) which when not in use automatically folds into the vertical position to allow access to the chamber by a wheelchair. An arcuate ramp 10 extends around the opening to the chamber 4 at floor level to provide easy access to the chamber 4 for a wheelchair. On the external wall of the housing is a coin slot 12 for accepting coins to open the door 6 and to initiate a photographic session with the user. Also provided is a photograph discharge chute 14 to discharge the finished photographs which may be passport sized or larger portrait sized photographs.

The wall 16, which the housing 2 has in common with the chamber 4, is provided with a window 18 through which a camera (not shown) located in housing can take portrait pictures of the customer seated in the chamber 4.

The camera is provided with appropriate flashlight facilities and the operation is set in train by the customer operating a series of controls of a control panel 20 mounted in the wall 16. The camera and the controls therefor are well know in the art and so will not be described here.

The sliding door and the apparatus controlling it will now be described in more detail.

The door 4 is generally semicircular and depends downwardly from a circular track in the roof of the chamber so as to be rotatable inside the chamber from a closed position in which it closes the opening in the chamber to a position in which it opens the opening and at the same time covers the camera window 18 and control panel 20. Thus, the control panel 20 and the camera cannot be accessed by the user until the door 6 is closed with the user inside the chamber 4.

The door 6, as shown in Figure 4, is supported by a cruciform beam structure 22. The structure 22 consists of two hollow beams of rectangular section which have been welded together at right angles to each other.

Three blocks 24, 26 and 28 upstanding from the upper end of the door 6 and circumferentially spaced at 900 intervals from one another are slotted into and secured to three respective ends of the four ends of the beam structure 22. The beam structure 22 thus carries the door 6.

Each arm of the cruciform structure 22 carries on its upper surface a respective carriage 30, 32, 34 and 36 equiradially spaced from the centre of the structure 22. The four carriages 30, 32, 34 and 36 run on an annular rail 40 secured to the under side of the roof of the chamber 4.

The four carriages are identical and Figure 5 shows a cross-section through one carriage 30. As can be seen, the rail is a sexagon in cross-section and is engaged on opposite sides by bearings carried by the carriage so that the carriage 30 is held captive on the rail 40 but can run around the rail for the full 3600.

The door 6 is thus suspended from the rails 40 and, if unrestrained, can be rotated freely around the rail for a full revolution.

The lower perimeter of the door 6 is accommodated in a slot 50 in ramp 10 to be spaced from the base of the slot 50 by say 5 mm. The inner face of the door carries adjacent the lower perimeter arcuate strip 52 of Nylon (RTM) which bears against the side wall 50A of the slot 50. It will be appreciated that by the manner in which the door is supported from above; there will be a tendency for the door to tilt towards the inner side wall 50A and to resist any forced move radially outwardly.

When the door 6 is closed, its opposite sides are still located within the outerwalls of the chamber 4 and hence the door is held captive by the chamber.

The door 6 is driven by a motor 60. A pulley wheel 62 is rigid with the cruciform structure having a common axis therewith. The motor 60 drives an auxiliary pulley wheel 64 though a clutch 66. An endless belt 68 couples the pulley wheels 62 and 64 together. The belt 68 is secured to the pulley wheel 62 by rivets 70 at one location. In operation when the motor 60 is energised in response to the insertion of a coin in the slot 12, it will drive the wheel 62 through the clutch 66, the pulley 64 and the belt 68 to cause the door 6 to open. As the door opens, the trailing edge 6A (see Figure 8) passes four circumferentially spaced detectors 72, 74, 76 and 78.

The detectors 72, 74, 76 and 78 are connected to a motor control circuit which controls the speed and direction of the motor. When the trailing edge 6A passes the detector 72, the motor 60 is driven in the forward direction from position d1 to d2 at a uniform acceleration. When the detector 74 detects that the trailing edge 6A has reached position d2, the motor continues at a constant speed.

Upon reaching position d3 the motor 60 is decelerated at a constant rate until the trailing edge 6A reaches position d4 as detected by the detector 78. At this point the motor 60 is halted and the door 6 will be in the fully open position.

Upon the user entering the chamber 4 he can operate a button (not shown) to close the door 6. Instead a detector may automatically detect the presence of a user and in response thereto cause the door to close. The trailing edge 6A of the door now becomes the leading edge and the motor 60 is driven in reverse to displace the door at constant acceleration from point d4 to d3 at constant speed from point d3 to d2 and at constant deceleration from d2 to d1 at which point the door is halted. The control here again is carried out under the control of the detectors 78 to 72. When the motor 60 is disengaged it is short circuited to resist any forced displacement in response to force displacement of the door. Of course, once a predetermined level of force is exceeded the clutch 66 slips and so allows the door to open.

The speed at which the door is displaced is more clearly illustrated in Figure 9 which shows a graph of displacement of the door versus speed.

The edge 6A of the door carries an infrared transmitter 80 located at the upper end directing an infrared beam parallel to, but spaced from, the edge 6A to a detector 82 located at the lower end. Should the edge 6A encounter an obstruction during its travel, the beam will be broken and a circuit (not shown) will be actuated to disengage the motor 60. An automatic delay device (not shown) will act a predetermined delay after the obstruction ceases to be sensed to cause the motor 60 to resume its operation.

When the door 6 is closed the opposite edges can be engaged from the inside and so in the event of a power failure the user inside can displace the door with sufficient force to overcome the clutch 66 and escape from the chamber 4. However, because the edges cannot be accessed from the outside when the door is closed, the arrangement is resistant to vandalisation.

The interior face of the door, because it is curved, helps to defuse any flashlight inside the chamber during a photographic session and so the quality of the photographs produced are better.

Because the belt 68 is riveted to the pulley 62 at one location, the door cannot be driven through 360C but is limited to displacement through just over 180 .

In a modification the photographic apparatus its associated cash box may be alarmed so that if tampered with an alarm (not shown) either visible and/or audible will be actuated and the door automatically closed.

In yet another modification an elongate brush member may be located in a channel 55 on the underside of the door to sweep any obstructions out of the path of the door and to maintain the chamber draft proof when the door is closed.
