Detailed Description of the Preferred Embodiments

Preferred embodiments in accordance with the present invention will now be described with reference to the accompanying drawings.

Refeming to Fig. 1, a base 1 of an automatic door closing device of any commercially available sizes is attached to a doorplate 10 by fasteners 11. A fixing device in accordance with the present invention includes a substrate 2 that is secured between the base 1 and the doorplate 10 for attaching a decorative outer casing 3.

Thus, the substrate 2 will not be damaged by the fasteners 11. Formed on top of the substrate 2 are two lugs 22 that extend along a horizontal direction. The lugs 22 rest on an upper side of the base 1 and thus prevent falling of the substrate 2. Each lug 22 has a positioning hole 23 for engaging with a fastener 24. The fastener 24 and the positioning hole 23 are preferably in threading engagement.

The decorative outer casing 3 includes an open side through which the base 1 and the substrate 2 are accommodated into an interior of the decorative outer casing 3 to thereby provide shield and protection. The decorative outer casing 3 may be engaged with the substrate 2. As illustrated in Fig. 1, two slots 31 (each preferably having an open end) and an 1 32 (preferably with an open end) are defined in an upper side of the decorative outer open ng 1 1 casing 33. The slots 31 are aligned With the positioning holes 23 of the substrate 2 and a stub 12 formed on the base 1 is enclosed by a periphery defining the opening 32.

Referring to Figs. 2 and 3, the substrate 2 is secured between the base 1 and the doorplate 10, in which the lugs 22 rest on the upper side of the base 1. The substrate 2 supports the decorative outer casing (now designated by 5) and is secured in place by fasteners 24.

Fig. 4 illustrates a second embodiment of the invention, wherein the substrate (now designated by 4) is longer and has an open slot 41 in each end thereof. Each open slot 41 is extended through by fasteners 11 for the base 1. Thus, the substrate 4 is firmly fixed between the base 1 and the doorplate 10. Formed on top of the substrate 4 are two lugs 42 that extend along a horizontal direction. The lugs 42 rest on an upper side of the base 1 and thus prevent falling of the substrate 4. Each lug 42 has a positioning hole 43 for engaging with a fastener 44.

The decorative outer casing 5 includes an open side through which the base 1 and the substrate 4 are accommodated into an interior of the decorative outer casing 5 to thereby 4 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 is 19 20 21 22 23 24 25 26 27 provide shield and protection. The decorative outer casing 5 may be engaged With the substrate 4. As illustrated in Fig. 4, two slots 51 (each preferably having an open end) and an opening 52 (preferably with an open end) are defined in an upper side of the decorative outer casing 5. The slots 51 are preferably L shape and aligned with the positioning holes 43 of the substrate 4 and a stub 12 formed on the base 1 is enclosed by a periphery defining the opening 52. The opening 52 has a length that is sufficiently long to allow sliding movement of the decorative outer casing 5 when the decorative outer casing 5 is attached to the base 1, best shown in Fig. 5. Thus, falling of the decorative outer casing 5 is prevented.

Fig. 6 illustrates a third embodiment of the invention, wherein the substrate (now designated by 6) has horizontal open slots 61 that are extended through by fasteners 11 for the base 1. Thus, the substrate 6 may be inserted into a space between the base 1 and the doorplate 10 and thus retained in place by the fasteners 11 that are extended through the open slots 61. Formed on top of the substrate 6 is a lug 62 that extend along a horizontal direction. The lug 62 rests on an upper side of the base 1 and thus prevents falling of the substrate 6. The lug 62 has a positioning hole 6-31 for engaging with a fastener 64.

The decorative outer casing 5 includes an open side through which the base 1 and the substrate 6 are accommodated into an interior of the decorative outer casing 5 to thereby provide shield and protection. The decorative outer casing 5 may be engaged with the substrate 6. As illustrated in Fig. 6, at least one slot 51 (preferably having an open end) and an opening 52 (preferably with an open end) are defined in an upper side of the decorative outer casing 5. The slot 51 is preferably L shape and aligned with the positioning hole 63 of the substrate 6 and a stub 12 formed on the base 1 is enclosed by a periphery defining the opening 52. The opening 52 has a length that is sufficiently long to allow sliding movement of the decorative outer casing 5 when the decorative outer casing 5 is attached to the base 1. The substrate 6 may be inserted into a space between the base 1 and the doorplate 10 and thus retained in place by the fasteners 11 best shown in Fig. 7. Thus, falling of the decorative outer casing 5 is prevented.

According to the above description, it is appreciated that the fixing device can be applied to all kinds of commercially available bases to provide required shielding and protecting purposes and to provide an aesthetically pleasing effect. In addition, the decorative cover plate may be replaced after a term of use to assure the aesthetically pleasing effect.

Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention. It is, therefore, contemplated that the appended claims will cover such modifications and variations that fall within the true scope of the invention.
