Definitions

• the invention relates to a cabmet for a display device having a display screen, the cabinet comprising: a rear part; a front part mounted to the rear part, having a window for the display screen, the rear part and/or the front part being able to hold the display device (2); and fastening means for fastening the front part to the rear part, the fastening means comprising pairs of cooperating members of the front part and the rear part, at least one pair having a resilient member, the cooperating members of the at least one pair having a shape and a position allowing manual mounting of the front part to the rear part and allowing disengagement of the at least one pair of members by a movement of the resilient member to make the front part and the rear part separable.
• the invention also relates to a display apparatus comprising such a cabinet and a display device having a display screen, the device being mounted in the cabinet and its display screen being visible through the window of the front part.
• a cabinet for a display device is known from EP 0 966 159 Al.
• the rear part of the known cabinet is mounted in a recess of a wall.
• the front part is fastened to the rear part by means of snap-ins which are positioned internally in the cabinet.
• the front part can be separated from the rear part by bending the resilient members of the snap-ins by inserting a screwdriver or the like into holes near the snap-ins.
• the front part may be fastened by means of screws instead of the snap-ins.
• the front part and the rear part can easily be separated or mounted when a repair is needed without having to use tools.
• a repair is needed without having to use tools.
• the advantages are that operation time is reduced, especially if repairs or checks are needed which require removal of the front part.
• the rear part and the front part may each comprise only one part but may alternatively be constructed from several parts. It is advantageous if the resilient member of the at least one pair of members is in a location where it is substantially invisible when the cabinet is in a normal operational position, hi that case, the member does not deteriorate the appearance of the cabmet. When the cabinet rests on a support surface, via a base the resilient member can easily be accessed and moved to disengage the resilient member from its cooperating member, thereby separating the front part from the rear part.
• the front part has a side wall which is directed substantially towards a support on which the cabinet rests in a normal operational position; and the resilient member of the at least one pair of members is positioned at the side wall of the front part; and extends from the front part to the rear part.
• the rear part has a first recess in an outer surface through which the resilient member is accessible, it can be avoided that the resilient member extends beyond the rear part to make the member manually accessible.
• Such a construction would increase the risk of accidentally moving the resilient member during normal use, handling or transportation, resulting in an undesired disengagement of the resilient member from its cooperating member. Moreover such a construction would deteriorate the appearance of the cabinet. Finally, such a construction would require more material, and would thus be more expensive.
• the rear part has a second recess into which the resilient member is sunk.
• the second recess may have a tapered shape to guide the resilient member into the correct position with respect to its cooperating member when moving the front part towards the rear part during mounting.
• At least two resilient members are present, spaced apart at the side wall of the front part.
• gaps between the front part and the rear part can be avoided or minimized in case the parts have a certain degree of flexibility.
• a rigid fixation can be achieved to meet handling and transportation specifications.
• the resilient member of the at least one pair of members has a third recess
• the cooperating member has a protrusion which is snapped into the third recess.
• the cooperating members of the at least one pair of members are snap-ins. In this case, when mounting the front part to the rear part, the cooperating members will snap into each other when the front part and the rear part are brought in the correct position for assembly.
• the display device is fixed by means of other snap-ins. If the display device is held by other snap-ins in the rear part, it is advisable that the front part has other protrusions which lock the other snap-ins when the front part is mounted to the rear part. Likewise, if the display is held by other snap-ins in the front part, it is advisable that the rear part has the other protrusions locking the other snap-ins. In this way it can be secured that the display device remains correctly positioned in the cabinet under all specified transportation conditions.
• the display device may be a Liquid Crystal type of display, a cathode ray tube or any other display device used in applications such as monitors and television-related applications.
• Fig. 1 is a schematically perspective view illustrating a first embodiment of the display apparatus comprising a display device and the display cabinet, in an opened position;
• Fig. 2 is a perspective view illustrating another embodiment of the display cabinet viewed in the direction of II in Fig. 1;
• Fig. 3 is the embodiment of Fig. 2 viewed in the direction of III in Fig. 1.
• the display apparatus of Fig. 1 has a display device 2 which has a display screen 3 mounted in a display cabinet 1.
• the cabinet 1 comprises a rear part 4 for holding the display device 2 and a front part 5 mounted to the rear part 4.
• the front part 5 has a window 6 for the display screen 3.
• the cabinet also comprises four fastening elements for fastening the front part 5 to the rear part 4.
• the fastening elements comprise pairs 10a, 10b; 12a, 12b of cooperating members of the front part 5 and the rear part 4. At least one pair has a resilient member 10a; 10b.
• the cooperating members 10a, 10b of the at least one pair 10a, 10b have a shape and a position allowing manual mounting of the front part 5 to the rear part 4 and allowing disengagement of the at least one pair of members 10a, 10b by a movement of the resilient member 10a; 10b. After disengagement, the front part 5 and the rear part 4 are separable.
• the resilient member 10a; 10b of the at least one pair is positioned at the outside of the cabinet 1. It is manually accessible, and has a shape and a position enabling it to be disengaged from its cooperating member 10b; 10a by a manual displacement.
• the resilient member 10a; 10b of the at least one pair of members 10a, 10b as shown in Fig. 1 is in a location where it is substantially invisible when the cabinet 1 is in a normal operational position.
• the front part 5 has a side wall 20 directed substantially towards a support S on which the cabinet 1 rests in a normal operational position.
• member 10a is the resilient member 10a of the at least one pair of members 10a, 10b.
• members 11a, 1 lb are another pair of cooperating members having another resilient member 11a.
• Member 12a is positioned at another side wall of the front part 5 opposite the side wall 20.
• the front part 5 By disengaging both 10a and 11a from their respective cooperating members, the front part 5 can be rotated around an axis parallel to the support surface and through the member 12b. After sufficient rotation, the member 12a is disengaged from its cooperating member 12b. If the members 12a, 12b are fixed, the front part 5 is mounted to the rear part 4 by rotating the front part 5 in the reverse direction as described above. If one of the members 12a, 12b is resilient, the front part 5 can be mounted to the rear part 4 by a linear movement of the front part towards the rear part. In Fig. 1, member 12b is resilient. Generally, more pairs of cooperating members are present next to the pair of cooperating members 12a, 12b so as to ensure adequate fixation of the front part 5 to the rear part 4.
• pairs of cooperating members could also be present at side walls other than those mentioned before. In that case the cooperating pairs at these other side walls need to have a resilient member to allow mounting of the front part 5 to the rear part 4. Moreover, the front part itself needs to be sufficiently resilient to bend in order to be able to disengage the cooperating members at the other side walls.
• the resilient member 10a is positioned at the side wall 20 of the front part 5. It extends from the front part 5 to the rear part 4.
• parts corresponding to parts in Fig. 1 have the same reference numerals.
• the cabinet 1 of Fig. 2 has a first recess 22 in an outer surface through which the resilient member 10a is accessible.
• members 10a and 10b are the resilient members of the at least one pair of members 10a, 10b; 11a, 1 lb.
• the cabinet 1 has a second recess 23 into which the resilient member 10a is sunk.
• the resilient members 10a, 11a are spaced apart at the side wall 20 of the front part 5.
• the resilient member 10a of the at least one pair of members 10a, 10b has a third recess 25 as shown in Fig. 2.
• the cooperating member 10b has a protrusion 26, which is snapped into the third recess 25.
• the member 10b has the third recess, while the member 10a has the protrusion which is snapped into the third recess.
• the cooperating members 10a, 10b of the at least one pair of members 10a, 10b maybe snap-ins.
• at least one of the cooperating members has a tapering shape allowing easy sliding of one over the other during mounting of the front part to the rear part.
• At least one other snap-in 30 holds the display device 2.
• Another protrusion 31 locks the other snap-in 30 when the front part 5 is mounted to the rear part 4.
