Blade bag for blades used with a circular saw
BACKGROUND OF THE INVENTION 
     The invention relates to a bag and more specifically to a blade bag for blades used with circular saws. 
     Presently, carpenters working on construction projects such as residential homes and commercial buildings often use a circular saw for cutting wood members. Usually the carpenter using the saw will not carry a spare blade with him and when the blade becomes dull or it breaks, it is necessary for the carpenter to return to the tool dispensing area or to a vehicle where spare blades are stored. Most of the time this causes a loss of time because the carpenter has to climb down from the structure being erected and walk to his supply area. 
     It is an object of the invention to provide a novel blade bag for blades used with a circular saw that can be carried on the belt of a carpenter. 
     It is also an object of the invention to provide a novel blade bag for blades used with a circular saw that can be installed in a conventional tool pouch. 
     It is another object of the invention to provide a novel blade bag for blades used with circular saw that can be fabricated from leather, canvas, and other materials. 
     It is an additional object of the invention to provide a novel blade bag for blades used with a circular saw that is economical to manufacture and market. 
     SUMMARY OF THE INVENTION 
     Applicant&#39;s novel blade bag for blades used with a circular saw has been designed to incorporate a unique double flap structure involving the rear wall member and the front wall member. The rear wall member has a major lower portion and at its top edge is a fold line which forms the lower edge of the rear wall flap member. The front wall member has a lower major portion whose top edge forms the lower edge of the front wall flap member. The blade bag has the front and rear wall members fastened to each other around its perimeter from the opposite ends of the fold line of the front wall member to form a pocket for removably receiving one or more saw blades for a circular saw. 
     The saw blades have a height approximating the height of the lower major portion of the rear wall member. When the blade is inserted into the pocket of the blade bag, most of the top half of the saw blade is inaccessible. In its open state, the rear wall flap member is folded upwardly and the front wall flap member is folded downwardly. In its closed state, the front wall flap member is folded upwardly and substantially hides from view the saw blades stored in the blade bag. The rear wall flap member is folded downwardly and fastening structure secures it to the front surface of the front wall flap member. If it wasn&#39;t for the unique double flap structure, it would be difficult to grasp the top of the saw blades while in their pocket in order to remove them since conventional bags only have a single top flap member. 
     The blade bag may be made from leather, canvas, or other types of material. The front and rear wall members may be stitched or riveted together in the critical area around the perimeter of the lower major portion of the front wall member. The outer configuration of the blade bag could have square lower corners or curved corners depending on the preference of the user. 
     Formed on the inner surface of the front wall flap member is a wrench pocket assembly for receiving a 1/2 inch open end wrench that is for removing a blade from a circular saw. The wrench pocket assembly may be open at both of its ends. It may be formed integrally with the top edge of the front wall flap member by having hook and loop fastener structure for opening and closing the lower end of wrench pocket assembly. 
     A belt loop assembly may be formed on the rear surface of the rear wall member. It may be structurally secured at its top end and have hook and loop fastener structure at its lower end which allows the blade bag to be installed on a carpenter&#39;s belt without the need for him to remove his belt from his waist. 
     An alternative embodiment of the blade bag uses multiple divider walls between the front and rear wall members of the blade bag. This produces multiple pockets for storing blades. Another embodiment shows the blade bag installed in the storage chamber of a tool pouch.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Applicant&#39;s novel blade bag for use with blades used with a circular saw will now be described by referring to FIGS. 1-7 of the drawings. The blade bag is generally designated numeral 10. 
     Blade bag 10 has a front wall member 12 and a rear wall member 14. Front wall member 12 has a fold line 20 at the top edge of lower major portion 18 which has a height H2. Front wall member 12 also has a front wall flap member 22 whose height is H1. 
     Front wall member 12 is secured to rear wall member 14 by rivets 24 or stitching that runs along the outer perimeter of lower major portion 18. 
     Rear wall member 14 has a major lower portion 26 having a fold line 28 formed adjacent its top end and its height is H3. Rear wall flap member 30 has hook and loop type fastener structure 32 secured to its front surface that mates with hook and loop fastener structure 34 attached to the front surface of front wall flap member 22. The height of rear wall flap member is H4. 
     A saw blade 36 is removably stored in pocket 38. 
     Belt loop assembly 40 has its top end secured by a rivet 42 or other fastening structure to the rear surface of rear wall member 14. The lower end of belt loop assembly 40 has hook and loop type fastener structure 42 secured to the respective belt loop assembly in the rear surface of rear wall member 14. 
     In the embodiment of the blade bag illustrated in FIGS. 3 and 4, a wrench pocket assembly 50 is formed on the rear surface of front wall flap member 22. It has an integrally formed rear flap member 54 that extends from fold line 56. The free end of rear flap member 54 has hook and loop fastener structure 58 which is easily opened in order to remove an open end wrench 60 therefrom. 
     Another embodiment of the novel blade bag is illustrated in FIG. 5 as being installed in a storage chamber 8 formed in a tool pouch 70. The tool pouch 70 has a rear wall 71 having a belt loop assembly 72 extending from its upper end. The belt loop assembly has a fold line 73 and a rivet 74 fastens it to form a closed loop. Rear wall 14 of the blade bag 10 is secured to the front surface of rear wall member 71 of tool pouch 70. 
     Another alternative embodiment of the blade bag is illustrated in FIGS. 6 and 7. It has a front wall member 81 and a rear wall member 82. Additionally it has divider wall 83, 84, and 85. These respective wall members have respective fold lines 87, 88, 89, and 90. They in turn form pockets 92, 93, 94, and 95. Flap members 100, 101, 102, and 103 function in the same manner as front wall flap member 22 of blade bag 10. A rear wall flap member 108 extends from fold line 110. Fasteners 111 and 112 secure rear wall flap member in its closed position.
