Title: Display pack having a rotatable security member

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a display pack and, more particularly, to an improved display pack having a rotatable security member disposed thereto so that a ratchet tool is operatably engaged to the security member. 
     2. Brief Description of the Prior Art 
     Hardware stores use display packs to display tools on walls, and these tool display packs each have a simple structure and can be hung on the hook so that the tool is fixedly connected to the display pack by way of mounting a transparent cover to the display pack with the tool received between the cover and the display pack. Generally, the conventional display pack provides an  a main advantage is  that customers can see the whole configuration of the tool. An inherent shortcoming of the tool display pack is that the tool, such as a ratchet tool, cannot be operated by customers. Furthermore, each of the  each of the tools have  has to be transported to a packing plant to be packed in display packs, and this requires a high cost. 
     Another type of display packs include  pack includes a board portion and a ring member disposed to the board so that a tool is simply supported and wrapped by the ring member. However, this type of display packs are  pack is easily broken simply by pulling the tool to break the ring member. Therefore, a thief can remove the tool and conceal it about his person. 
     The present invention intends to provide an improved display pack to mitigate and/or obviate the above-mentioned problems. 
     SUMMARY OF THE INVENTION 
     The present invention provides a display pack and comprises a board and a rotatable security member. The board has a first hole and a second hole respectively defined therethrough, wherein the second hole has a toothed inner periphery. An inverted U-shaped frame extends perpendicularly from a front surface thereof, with the second hole being located between two extending portions of the frame. The rotatable security member includes a polygonal head and a shank extending from the head. The shank has a least one flange extending radially from a free end thereof and a toothed periphery defined in an outer periphery thereof near the flange such that the rotatable security member is rotatably inserted into the second hole with the toothed periphery being engaged with the toothed inner periphery. 
     It is an object of the present invention to provide a display pack which has a rotatable security member disposed thereto which is cooperated with a ratchet tool such that the ratchet tool can be operated within a limit  limited angle. 
     It is another object of the present invention to provide a display pack having a rotatable security member disposed thereto so as to prevent the tool engaged with the rotatable security member from being taken away from the display pack without permission. 
     Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to the drawings and initially to FIGS. 1 through 3, a display pack in accordance with the present invention generally includes a board  14  and a rotatable security member  20  wherein the board  14  has a first hole  15  defined in a position near a top area thereof so as to be hung on a rack (not shown) for example and a second hole  16  defined in a position near a middle portion thereof. The second hole  16  has a toothed inner periphery  161 . The board  14  has an inverted U-shaped frame  11  extending perpendicularly from a front surface thereof with the second hole  16  being located between two extending portions of the frame  11  and a limit plate  13  is connected between the two extending portions of the inverted U-shaped frame  11 . 
     The rotatable security member  20  includes a polygonal head  21   22 , a hexagonal head in this embodiment, and a shank  22   extending from one of two sides of the head  21   22 . The shank  22   has at least one flange  221  extending radially from a free end thereof and at least two slits  23  defined longitudinally therein which open to the free end. The flange  221  has a diameter slightly larger than that of the second hole  16  so that the flange  221  is engaged with a rear surface of the board  14  when the shank  22   of the rotatable security member  20  is inserted into the second hole  16  by force. A toothed periphery  222  is defined in an outer periphery of the shank  22   and is located near the flange  221  such that the rotatable security member  20  is rotatably inserted into the second hole  16  with the toothed periphery  222  being engaged with the toothed inner periphery  161 . It is noted that the toothed periphery  222  and the toothed inner periphery  161  are made by plastic and have small teeth so that the rotatable security member  20  is rotatable in the second hole  16  with the toothed periphery  222  shifting on the toothed inner periphery  161 . 
     Further referring to FIG. 4, a ratchet tool  30  has its operation head portion  31  mounted to the rotatable security member  20  and its shank portion  32  extending between the two extending portions of the inverted U-shaped frame  11  such that a customer (not shown) can operate the ratchet tool  30  by swinging the shank portion  32  of the ratchet tool  30 . The relationship mentioned above between the toothed periphery  222  and the toothed inner periphery  161  will cause the ratchet tool  30  to be operated as if it is fastening or unfastening an object. 
     Accordingly, the present invention allows customers to operate the ratchet tool  30  attached to the display pack in accordance with the present invention and the ratchet tool  30  is easily to be  attached to the display pack. 
     FIGS. 5 and 6 respectively show different embodiments of the display pack in accordance with the present invention with a shorter board  14 ′ and a longer board  14 ″. 
     Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
