Attachment device

Abstract

An attachment device (1) for an apparatus (10), which apparatus (10) comprises a fixed cable (2) with a connector (12) at its free end. The attachment device (1) comprises a first plate member (3) and a second plate member (4), which by means of a hinge member (7) are rotatably connected to each other about a hinge axis (5). Hereby, they can rotate between a closed position, in which the plate members (3, 4) lie against each other, and in which the attachment device (1) defines a through-going opening (6) for the cable (2), and an open position, in which the cable (2) can be removed from the attachment device (1). The first plate member (3) comprises a first locking slot (83) and the second plate member (4) comprises a second locking slot (84). The first and second locking slots (83, 84) are aligned in the closed position, whereby a locking member (13) can be inserted through both locking slots (83, 84) and lock the attachment device (2) in the closed position, in which the cable (2) cannot be out pulled through the through-going opening (6). The hinge axis (5) is parallel with the first and second plate members (3, 4) and that the through-going opening (6) is tubular.

MODES FOR CARRYING OUT THE INVENTION

(10) FIGS. 1-5 are line drawings of a first embodiment of an attachment device 1 according to the invention shown from different angles. FIG. 1 is showing the attachment device 1 in a perspective view. The attachment device 1 comprises a first plate member 3, a second plate member 4 and a hinge member 7 interconnecting the first and second plate members 3, 4. As indicated in FIG. 2, the first plate member 3 comprises a rubber plate part 73 and a first rigid plate part 93. Likewise, as indicated in FIG. 4, the second plate member 4 comprises a second rubber plate part 74 and a second rigid plate part 94. The hinge member 7 comprises a flexible slitted tubular rubber part 7 with a through-going bore 6 and with a hinge axis 5 extending in the longitudinal direction of the tubular rubber part 7 approximately at the centre of the bore 6. The flexible tubular rubber part 7 and the first and second rubber plate parts 73, 74 together form a uniform rubber body. The first rigid plate part 93 is attached in a recess in the outer side of the first rubber plate part 73. Likewise, the second rigid plate part 94 is attached in a recess in the outer side of the second rubber plate part 74. Thus, the first rigid plate part 93 is encircled by a first rubber edge part 53, and the second rigid plate part 94 is encircled by a second rubber edge part 54. The first and second rigid plate parts 93, 94 are made of 0.8 mm thick stainless steel sheet.

(11) The first and second plate members 3, 4 are provided with through-going Kensington® slots 83, 84. Thus, the Kensington® slots extends through both the first and second rubber plate parts 73, 74 and the first and second rigid plate parts 93, 94. In a closed position, where inner sides 63, 64 of the first and second plate members lie against each other, the Kensington® slots are aligned.

(12) FIG. 2 is a front view, showing the outer side of the first plate member 3 and the hinge member 7. FIG. 3 is a side view of the attachment device 1 in an open position. FIG. 4 is a back view of the attachment device 1, where the outer side of the second plate member 4 and the hinge member 7 is visible. The attachment device 1 is symmetric about a plane extending between the first and second plate members 3, 4, whereby the views of FIGS. 2 and 4 are identical.

(13) FIG. 5 is a photo showing the attachment device 1 lying on a table surface 15 in an open position ready to receive a cable from a device to be attached. Due to the flexible material of the rubber part 7, the first and second plate members 3, 4 can be rotated against and away from each other about the hinge axis 5, whereby it is possible to arrange a cable in the bore 6 of the hinge part 7. After a cable insertion, the plate members 3, 4 cab be rotated back against each other to a closed position. In the closed the position, the rubber material of the inner sides 63, 64 of the first and second plate members 3, 4 lie against each other. In the closed position, the slit of the bore 6 is closed, whereby the cable 2 cannot escape.

(14) In FIG. 6, the attachment device 1 is arranged on a cable 2 with the cable 2 extending through the bore 6 of the hinge member 7.

(15) In FIG. 7, a keyed Kensington® lock 8 is attached to the attachment device 1. As shown in FIG. 8, a T-bar™ 13 is inserted through the aligned Kensington slots 83, 84 and rotated 90 degrees by means of the key 14. Hereby, the Kensington® lock and the attachment device 1 are locked together and cannot be separated without the key 14. In this position, it is not possible to detach the attachment device 1 from the speakerphone 10, as the first end of the speakerphone cable 2 is permanently fixed to the speakerphone 10, and the other end comprises a USB plug 12, which is too large to pass through the bore 6 of the attachment device 1. The Kensington Lock® comprises a metal wire 9. One end of the metal wire 9 is attached to the locking part of the Kensington Lock® 8. The other end, which is not visible here, of the wire 9 comprises a loop, and by means of this the wire 9 is looped around a fixed part such as a table leg. Thus, the speakerphone 10 cannot be removed from the table without destroying the lock 8, the cable 2 or the attachment device 1.

(16) The attachment device 1 is dimensioned to be used with Kensington® locking devices. Therefore, the slots are 7 mm to 7.25 mm long and 3 mm to 3.25 mm wide. The corners of the slots have a radius of 1 mm. The total thickness of the first and second plate members together is 2.50 mm to 4.00 mm. The rigid plate parts 93, 94 of stainless steel are 0.8 mm thick. The rigid plate parts 93, 94 are approximately 27 mm wide, measured in the direction of the hinge axis 5, and 27 mm in the direction orthogonal hereto.

(17) The length of the hinge part 7 is the same as the width of the first and second plate members 3, 4 and is about 30 mm.

(18) The bore 6 has a diameter of approximately 4 mm.

(19) The rigid plats parts 93, 94 of stainless steel ensure an efficient interlocking with the Kensington® lock. The outer edges of rubber reduces the risk of the attachment device making marks in the surface 15 of the table and also reduces noise due to contact between the attachment device 1 and the table surface 15 if the speakerphone 10 or other device is moved. This is especially relevant if the speakerphone 10 is moved in the middle of a conference call, as noise is distracting for the conference call participants who receive sound from the speakerphones 10 microphone.

(20) The invention is not limited to the embodiment disclosed here. The attachment device 1 can be of other materials, such as plastic or metal. It can also have different shapes.

(21) The attachment device according to the invention is not limited to be used with Kensington® locks. Thus, locking slots 83, 84 with other dimensions can be provided.

(22) The attachment device 1 according to the invention can also be used to lock a cable alone, if the cable has connector in both ends, which are too big to pass through the bore 6 in the closed position of the attachment device 1.
