Sweden-Sverige (SE) 15036/72 (71) (72) Berndt Ebbe Frick, Herrg & rdsvägen 9 »135 00 Tyresö, Sweden-Sverige (SE) (7 * 0 Oy Kolster Ab (5 * 0 Soundproof cover for remote printer - For This invention relates to sound-insulating shields, and more particularly to sound-insulating shields intended to surround a remote printer.

It is already known to construct sound-insulating covers with a base part from which rise two side walls, a front wall and a rear wall and a top part, and in which the internal volume of the cover is only slightly larger than the volume of the noise-generating device. The cover is coated on the inside with one or more sound-insulating layers in order to effectively reduce the noise level of the noise-generating device.

In the practical application of such sound-insulating guards, it has proved very difficult for service personnel to carry out maintenance, inspection or similar action on a noise-generating device. It has also been difficult to design the cover in such a way that the device can be easily used by the operating staff, i.e. the device must be easily accessible despite the cover.

Efforts to design the soundproof cover so that maintenance, inspection, and similar measures can be easily performed have appeared to result in low sound insulation. In most cases for very little sound insulation. If, in any case, a sound-insulating effect has been achieved with the cover, it has generally been necessary to open the entire cover in order to allow the desired inspection by the maintenance staff. Such an operation requires a lot of space above the cover and eliminates the possibility that two covers can be placed on top of each other and the other can be used while sitting and the other while standing.

The object of the present invention is to provide instructions for a sound-insulating cover, in which the above-mentioned disadvantages have been eliminated and which arrangement has simply succeeded in maintaining a high level of sound insulation for the protective structure while the above-mentioned wishes can be fulfilled.

What is characteristic of the sound-insulating cover according to the present invention is defined in the characterizing part of claim 1.

The presently proposed embodiment having the features of the present invention will be explained in more detail with reference to the accompanying drawing.

Figure 1 shows a side view of a sound-insulated cover constructed according to the invention.

Fig. 2 shows the cover of Fig. 1 in a position where the remote printer is pulled out from inside the cover to a position suitable for maintenance, inspection or similar operation.

Figure 3 shows a side view of a stand for two sound-insulated covers placed one above the other.

Figure 1+ is a front view of a stand for six guards.

Figure 1 thus shows a side view of a sound-insulating cover 1 intended to surround the remote printer 2. The sound-insulating cover has a bottom part 1a from which rise two side walls Ib, le, a front wall Id and a rear wall le and a top part lf. The internal volume of the cover 1 is adjusted so that it is only slightly larger than the volume of the noise generating device 2. In addition, the sound-insulating cover is provided with one or more sound-insulating layers on the inside in order to reduce the noise level outside the cover compared to the noise level inside the cover.

Figure 1 shows the cover 1 in a mainly assembled position and shows that the front wall Id is provided with a number of doors to access the device 2. Thus, it can be mentioned that the door 10 is intended to be folded up to access the keyboard of the remote printer 2 (this door is shown in Figure 2). 1 upside down). The door 10a can be folded up by means of the hinge 11a to access the automatic transmitter. The door 10 is connected to the front wall Id by means of a hinge 11 so that the inner surface of the door 10 can act as a support for the manuscript or the like by means of the strip 10 '. In addition, there is a hatch 10b, which can also be turned up by means of the hinge 11b to allow the collection cup or the like to be removed, which collection cup is for waste from perforation of the strip. In addition, there are a number of pushbuttons 12 for controlling the switching device in the remote printer. A window 12a is placed on the cover right next to the buttons to allow monitoring of the entry of the strip to be fed to the perforating device.

Examining the front part Id, it will be seen that the entire front part can be turned down around the hinge 13, which hinge is placed in the base part 1a. From this it becomes clear that when the front wall Id is lowered, a part of the side wall Ib 'and a part of the main part If accompany the front part Id. Similarly, part of the side wall le also follows with the part Id.

In addition, it can be envisioned that the front part has an internal door 10c, which is intended to extend from the keys and against the inner surface of the front part Id. Door 10c is located behind the keys in the closed position of the cover. By means of the hinge 11c, the door 10c is fixedly connected to the front part Id. By means of a flexible member, not shown in the figure, the door 10c is pressed against the other cover so that when the front part Id is closed against the cover, the free edge of the door 10c passes over the keys and descends behind the keys by means of a control device not shown.

The main part 1f is likewise formed as a hatch and can be turned up to the position shown in Fig. 2 by means of a hinge located at the top of the rear wall. The main part lf has a window lU through which the messages coming from the remote printer can be read. As for the upturned position of the main part, this is most evident from the position shown in Fig. 2.

The invention is based on the fact that the base plate 15 is arranged inside the cover 1 and at a small distance from the base part 1a. The distance is, of course, calculated from the surface of the base part facing the interior of the cover. The base plate 15 is intended to support a noise-generating device 2, in this case a remote printer, the main casing or housing of which has been removed. For clarity, the remote printer is only outlined in Figure 2.

The invention starts from the fact that at least the front wall Id is formed such that it cooperates with the rest of the housing 1 via the hinge 13, thus enabling the front wall Id to be turned to the noise-generating device revealing position shown in Fig. 2 and the noise-generating device surrounding, i.e. closed in principle shown in Figure 1.

The invention is also based on the fact that in the revealing position of the noise generating device shown in Fig. 2, the noise generating device 2 can be pulled out from inside the cover 1 to a position suitable for maintenance, inspection and the like. The hinge 13 must be practically located in the base part 1a. The noise-generating device 2 must co-operate with the cover so that it can be pulled out a distance corresponding to the length of the device.

The base plate 15 cooperates with the guides and is arranged to be moved relative to the cover 1 by means of these guides. Here, it is suitable to allow the guides and the base plate to be arranged parallel to the base part 1a. A guide part is placed on the plate 15 and is given the reference number 16a. This part cooperates with the part placed in the cover and attached to the side part Ib. This part is not shown in Fig. 2. The plate 15 has two conductors and the rear conductor l6a in cooperation with the part l6b attached to the side part le. The guides 16a and 16b are provided with holes at the top, with which holes the stop member 17 can be brought into cooperation and thus prevent the base plate from being pulled out of the cover 1 too long. By placing the holes at different distances, the slab 15 can be stopped at a predetermined distance from the cover.

The main part lf cooperates with the cover via a hinge, which is not shown in Fig. 2, but is nevertheless placed at the upper edge of the rear wall. By means of the member 18, the main part lf supports the roller 19, which forms a paper web, which is fed through the remote printer 2 to write the information. The main part 1f further comprises a holder 20 for a roller 22, which roller forms the tape on which the communications are stored by pressing holes in the tape at the points required for the communication. The tape 23 is fed to a perforating device known per se, which is connected to the remote printer 2 in a manner known per se. It should be noted here that both the holders 18, which are two for attaching the roller 19, and the holder 20 are fixedly connected to the pivotable main part lf. Thus, the advantage is obtained that both the roller 19 and the roller 22 rise from inside the cover when the part lf is turned up and thus simplify and improve the handling when the rollers have to be replaced or when they have to be repaired. Besides, the rollers do not form any obstacle in the inspection when the device 2 adopts the position shown in Fig. 2.

the invention also comprises a stand, which makes it possible to support guards such as those mentioned above. The stand consists of a pair of vertical columns 31, only one of which is shown in Figure 3 when this is shown in a side view. Out of the posts 31, first, at a right angle, two support rails 32 for the first cover 33, and second, at an acute angle, two support rails 3 * + for the second cover 35. The cover 33 is provided with a front portion 33a and a top portion 33b, which can obtain the dotted line position shown in Fig. 3, while the remote printer 33c can be pulled out to the dotted line position shown in Fig. 3.

The support rails 32 connected at right angles to the posts 31 are each supported by their legs 36 spaced apart from the posts 31. At a sharp angle, the support rails 3 ^ connected to the posts 31 are positioned above the support rails 32 connected at right angles to the posts.

The coupling unit 36 for the noise-generating devices inside the covers 35 and / or 33 is located next to the posts 31 and at an acute angle next to the support rails 3 * + connected to the posts. This structure means that the device inside the cover 33 can be handled by a person sitting in a chair, while the device inside the cover 35 can be handled by a standing person.

Figure 4 shows a front view of a pedestal structure on which six sound-insulating covers can be mounted. For this purpose, four posts 31 are required, which are placed next to each other and from which the four support rails 32 and the support rails 3 ^ leave. It can be seen from Figure U that the guards 33 or guards 35 can be opened as shown in Figure 3 and the noise generating device can be pulled out from inside the guard to a position suitable for maintenance, inspection or similar operation without being obstructed by other guards.

The invention is not limited to the exemplary embodiment presented above, but may be modified within the scope of the following claims. Thus, it can be mentioned that the embodiment comprises partly a base part for the cover and partly a plate 15 for the device 2. It is, of course, possible to construct these together as a single unit and to make the base part pull-out from inside the cover, where the other parts may be held together by the body or the like. It is also possible to replace the plate 15 with transverse rods against which the support members of the device 2 are allowed to rest.
