DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal computer anti-theft restraint for connecting a locking cord to a locking slit of a personal computer to prevent the personal computer from being stolen.

[0002]

2. Description of the Related Art Locking slits are provided on a personal computer main body to prevent theft of a personal computer displayed on a display shelf or the like.
The restraining base attached to the slit and the display shelf or the like are connected by a restraining cord (metal wire or the like). The restraining base and the restraining code are referred to as a personal computer anti-theft restraint. A conventional restraining device is a sliding base that rotates and slides as a restraining base.
Uses two metal plates. Each metal plate has a locking claw that engages with the PC body when inserted into the slit.By opening each, the maximum spacing between the locking claws becomes smaller than the length of the slit, and by closing both, The gap between the hooks is widened, and the hooks engage with the personal computer body, and at the same time, the insertion holes of both metal plates communicate with each other so that the restraining cord can be wound around.

[0003]

A problem with the conventional restraint is that the restraint base is large. If the individual restraint is suitable for each personal computer, the length of the hook and the opening of the two metal plates can be adjusted according to the length of the slit to limit the size of the restraint base. However, if it is used as a general-purpose restraint, it will be necessary to cope with slits of all sizes and shapes, so a large metal plate must be used. Such a large restraining base causes an increase in the installation area of the personal computer main body with respect to a display shelf or the like, and improvement has been desired. Therefore, in order to reduce the size of the restraining base, a study was conducted to develop a restraining base having a new structure.

[0004]

As a result of the study, what has been developed is a restraining device comprising a restraining base attached to a locking slit of a personal computer main body and a restraining cord hung around the restraining base, and the restraining base is inserted into the slit. The main body includes a cover that covers the base body, and the base body is inserted from the slit and is engaged with the personal computer body when rotated by less than 180 degrees. Are connected via a constricted portion having a slit width of the maximum external width, and the cover is provided with a restricting portion that can be inserted into the slit excluding the constricted portion of the base main body and the restriction cord insertion hole when the cover is covered with the base main body. And a constraining cord communication hole communicating with the
When the cover is laid on the base body that is engaged with the PC body by inserting the hook into the slit, the restricting part of the cover is inserted into the slit to regulate the rotation of the base body, and the base body and the PC body This is a personal computer anti-theft restraint that will no longer be disengaged from the personal computer.

The restraining device of the present invention comprises a restraining base consisting of two members, a base body and a cover. The base body has the essential function of restraining the restraining cord to the personal computer body. It has the function of tying to. Since the constricted portion of the base main body has a maximum outer width smaller than the slit width, when the hook portion is inserted from the slit such that the constricted portion is positioned in the slit, the base portion can be rotated with the knob. At this time, if the rotation is smaller than 180 degrees, the engaging portion engages with the personal computer main body because the angle formed by the slit is different from that at the time of insertion into the slit. For example, a shape in which a T-shaped projection is connected to the knob at the lower end, a horizontal bar portion is a hook portion, and a vertical bar portion connected to the knob portion is a constricted portion is considered.

The cover regulates the rotation of the cover with respect to its own slit by inserting the restricting portion through the slit excluding the constricted portion of the base body. At the same time, (1) the maximum outer width of the constricted portion is virtually equal to or larger than the slit width by directly holding the constricted portion by the restricting portion, or (2) the base body covering the rotation control of the cover itself is covered. By working, the rotation of the base body is restricted. For this reason, if the cover is covered after the engaging portion of the base main body is engaged with the personal computer main body, the engagement state between the base main body and the personal computer will be maintained, and the base main body will be fixed to the personal computer by the cover. Is realized. The base body and the cover are unified and separated from each other by hanging the restraining cord through the communicating restraining cord insertion hole and the restraining cord communicating hole.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a use state of the restraint 1 of the present invention, FIG. 2 is a perspective view of the base body 2 viewed from the front, and FIG. 3 is a perspective view of the cover 3 viewed from the back. . As shown in FIG. 1, a restraining device 1 of the present invention has a restraining base 6 attached to a locking slit 5 provided on the back surface of a personal computer main body 4 and the like, and a restraining cord such as a metal wire wound around the restraining base 6. 7 is wound around a pillar 8 or the like and locked with a lock 9 or the like to prevent theft. FIG.
As is apparent from the above description, the restraint base 6 of the restraint 1 of the present invention needs only to have a size sufficient to hang the restraint cord 7 and is very compact as compared with the conventional restraint. I understand.

In the restraining device of the present invention, the restraining base is composed of a base body and a cover, and the restraining cord and the lock are conventional ones. As shown in FIG. 2, the base body 2 of the present example has a knob 10 having a thickness equal to or less than the slit width as a whole.
It is composed of a constricted part 11 and a hook part 12, and each part 10, 11, 12 is an integral metal product. The knob 10 has a substantially semicircular shape, and has a rectangular restraining cord insertion hole 13 substantially at the center. The constricted portion 11 and the hooking portion 12 together form a T-shaped protrusion, the constricted portion 11 is connected to a T-shaped vertical bar portion connected to the knob 10 at the lower end, and the hooked portion 12 is connected to the upper end of the constricted portion 11. It corresponds to the horizontal bar. The constricted portion 11 has a substantially rectangular cross section. In this example, the diagonal length is equal to or less than the slit width, and the maximum outer width is equal to or less than the slit.

As shown in FIG. 3, the cover 3 has an appearance in which a flat oval block is divided in half, and has a cover hole 15 in which the knob of the base body is fitted in the center of the elliptical flat portion 14. The cover hole 15 is provided vertically through a restraining cord communication hole 16. In the center of the upper edge and the lower edge of the covering hole 15, a pair of restricting pieces 17, 17 as restricting portions to be inserted into slits excluding the constricted portion is provided. These are one-piece synthetic resin products. As will be described later, when the knob is fitted into the covering hole 15, the elliptical flat portion 14 and the linear portion 18 of the knob are formed.
(See FIG. 2) are aligned on the same plane and are in contact with the outer surface of the personal computer main body. After being attached to the personal computer main body, as shown in FIG. 4 Appears to adhere to the outer surface.

FIG. 4 is a front perspective view of the vicinity of the slit 5 showing a state where the base body 2 is about to be inserted into the slit 5 (operation 1). FIG. FIG. 6 is a perspective view showing a state in which the cover 3 is to be covered (operation 2), and FIG.
FIG. 7 is a cross-sectional view of the vicinity of the slit 5 near the slit 5 showing (operation 3). FIG. 7 is a cross-sectional view of the vicinity of the slit 5 in the state of FIG. FIG. 7 is a front perspective view of the vicinity of a slit 5 showing a state (operation 4).

The attachment of the restraining base of this embodiment to the personal computer body is performed in the following procedure. First, as shown in FIG. 4, with the base main body 2 in an upright state, the knob 10 is inserted into the slit 5 while holding the knob 10 by hand. As described above, since the thickness of the base body 2 is equal to or less than the slit width, the constricted portion 11 is easily formed.
Can be inserted into the slit 5. At this time,
If the width of the knob (length in the vertical direction in FIG. 4) is longer than the length of the slit, or if only the knob is thicker than the slit width, up to the knob is inserted into the slit. There is no danger that

Next, as shown in FIG.
The base main body 2 is rotated by 90 degrees with the knob 10 in a state where the constricted portion 11 is positioned, and the hook 12 is engaged with the PC main body 4. Since the engaging portion 12 corresponds to the horizontal bar portion of the T-shaped projection, it is naturally rotated from the inserted state so that the personal computer main body 4 can be rotated.
Engages. In this example, as described later, the restricting pieces 17, 17 of the cover 3 and the constricted portion 11 are in contact with each other, so that the constricted portion 11 is rotated by 90 degrees so as to be horizontal. With respect to the base body 2 that has been rotated in this way, the regulating piece 1
The cover 3 is covered so that the slots 7 and 17 are inserted into the slits 5.

As shown in FIGS. 6 and 7, the cover 3 covers the knob portion 10 of the base main body 2 exposed from the slit 5 by fitting it into the covering hole 15 to cover the elliptical flat portion 14 with the slit 5. It is brought into contact with the outer surface of the personal computer 4 in the vicinity. At this time, the restriction pieces 17 and 17 are inserted into the slit 5 except for the constricted portion 11, and the rotation of the cover 3 with respect to the slit 5 is restricted. Accordingly, the rotation of the base body 2 with respect to the slit 5 is restricted by the rotation restriction of the cover 3. Thus, the maximum outer width of the constricted portion 11 is virtually larger than the slit width, so that the rotation of the base body 2 is directly restricted.

The restricting pieces 17 and 17 of this embodiment are in the form of a pair of thin plates sandwiching the covering hole 15, but as a general restricting portion, as described above, indirectly or directly by a combined action. This restricts the rotation of the base body, regardless of its size and shape. Also, although the regulation piece 17 of this example looks weak in strength,
Actually, since it is in contact with the constricted portion 11 of the base body 2 which is a metal product, it is reinforced by the constricted portion 11 and secures necessary and sufficient structural strength. In order to increase the strength of the restricting portion, the length of the restricting piece may be increased as long as the remaining slits allow.

In the restraint base 6 thus mounted, the restraint cord insertion hole 13 of the base body 2 and the restraint cord communication hole 16 of the cover 3 are in communication with each other. As shown in FIG. The constraint cord 7 such as a wire can be looped around. Due to the wrapping of the restraining cord 7, the base body 2 and the cover 3 are not integrally separated from each other, and the rotation of the base body 2 by covering the cover 3 is maintained except for releasing the restraining cord 7. It is.

[0016]

According to the present invention, the restraint device for theft prevention of a personal computer has a very simple mounting of the restraint base and can be carried out by anyone, and enables a necessary and sufficient restraint cord to be wrapped around to prevent theft. . Above all, the base of the restraint can be made very small compared to the conventional restraint, and there is no need to limit the installation of the PC main body. You don't have to worry about the appearance of the product. In addition, a smaller constraining base means that less material is required, which leads to cost reduction. Thus, the present invention improves the handling of the restraint, especially the restraining base, while at the same time allowing for lower costs.
