Measuring device for use in furniture construction
This invention relates to measuring devices. More particularly, this invention relates to measuring devices used in furniture construction, and in particular in connection with caning. 
     Caning is a process of hand-weaving furniture which has drilled holes in its framework, and consists of weaving strands of a reed-like material called cane through the drilled holes in the framework to create a desired pattern. Cane is obtained from the outside bark of rattan, a jungle vine found in Indonesia and Malaysia. The outside bark is stripped from the main stem of the rattan plant, and cut into strips of various widths to form cane. The articles of furniture which may be formed by the weaving of cane through holes in a framework include chairs, tables, and cabinets. In general, the cane is cut in seven different sizes: (i) carriage (11/2 mm); (ii) superfine (13/4 mm); (iii) fine-fine (2 to 21/4 mm); (iv) fine (21/2 mm); (v) narrow medium (23/4 mm); (vi) medium (3 mm); and (vii) common (31/2 mm), with carriage being the smallest and common being the largest. The size of cane which is used is dependent upon the size of the openings in the framework and the distance between the openings. 
     It is therefore an object of the present invention to provide a measuring device, or gauge, which enables one to determine readily the size of cane to be employed in caning an article of furniture. 
     In accordance with an aspect of the present invention, there is provided a measuring device which comprises a top face portion, a bottom face portion, and at least three side face portions. The device also includes at least one protrusion extending distally from one of said at least three side portions. The at least one protrusion has at least one segment of a specified width and shape. The at least one segment is capable of fitting within an opening of a corresponding width and shape. The term &#34;width&#34;, as used herein, means the width of any shaped object and including the diameter, of circular, conical, or cylindrical openings. The device also includes at least one indentation in at least one of the said at least three side face panels. The at least one indentation has a specified width and is capable of receiving an object having the specified width. At least one indicia is located on at least one of the top face portion and the bottom face portion, and is adjacent the at least one indentation. The at least one indicia is indicative of the size of the object. Also, the device further includes at least one indicia located on at least one of the top face portion and the bottom face portion for determining a distance between two points of reference, such as, for example, the distance between two openings in an article of furniture. 
     In one embodiment, the at least one protrusion has a first segment immediately adjacent the side face portion, and at least one additional segment. The first segment has a width greater than that of each of the at least one additional segment(s). In one preferred embodiment, the at least one protrusion includes at least two additional segments, and the width of each of said at least two additional segments decreases as the at least two additional segments progress from proximal to distal in relation to the side face portion. 
     Preferably, each of the first segment and the at least one additional segment includes an indicia of the width of the first segment and of the at least one additional segment. 
     In another embodiment, the device includes at least two indentations in at least one of said at least three side face panels. 
     In yet another embodiment, the device further comprises an indicia of the size of an opening, and such indicia is adjacent the at least one indicia for determining a distance range between two points of reference. 
     In a further embodiment, the device further comprises an indicia of the width of an object, and such indicia is adjacent the at least one indicia for determining a distance range between two points of reference. 
     In a most preferred embodiment, the protrusion has four segments, with the segments having widths of 5/16&#34;, 1/4&#34;, 3/16&#34;, and 1/8&#34; as the segments progress from proximal to distal with respect to the side face portion. The device also includes seven indentations in one of the side face portions, with each indentation corresponding to one of the seven cane sizes used in caning. Printed on at least one of the top panel and the bottom panel are seven indicia for determining a distance between two adjacent openings in an article of furniture. Also printed adjacent each of these seven indicia are indicia which indicate an opening size, and indicia which indicate a cane size. In such an embodiment, one can determine the opening size, the distance between two adjacent openings, and cane size with a single device.

     Referring now to the drawings, the measuring device or caning gauge 10 includes a top face 12, a bottom face 14, and side faces 16a, 16b, 16c and 16d. Extending from side face 16b of caning gauge 10 is protrusion 18, which is employed in determining the width or diameter of an opening. Protrusion 18 includes four segments, 19a, 19b, 19c, and 19d. Each segment has an indicia 22a, 22b, 22c, and 22d, of the width of the respected segments 19a, 19b, 19c, and 19d. It is to be noted that the segments 19a, 19b, 19c, and 19d decrease in width as the segments extend outwardly from proximal to distal from side face 16b. In diameter, of 5/16&#34;, segment 19b has a diameter of 1/4&#34;, segment 19c has a diameter of 3/16&#34;, and segment 19d has a diameter of 1/8&#34; . Thus, protrusion 18 may be inserted into an opening in an article of furniture until one of segments 19a through 19d fits snugly within the opening. By referring to the indicia 22a, 22b, 22c, or 22d, of the segment which fits snugly within the opening, one then can determine the width or diameter of the opening. 
     Side face 16d includes indentations 20a, 20b, 20c, 20d, 20e, 20f, and 20g, which are of various widths which correspond to various widths of the cane. Printed on top face 12, and adjacent each of indentations 20a through 20g are indicia 21a, 21b, 21c, 21d, 21e, 21f, and 21g. Each of these indicia refers to a particular size name of cane of a specified width. Indicia 21a is carriage (11/2 mm); indicia 21b is superfine (13/4 mm); indicia 21c is fine-fine (2 to 21/4 mm); indicia 21d is fine (21/2 mm); indicia 21e is narrow medium (23/4 mm); indicia 21f is medium (3 mm); and indicia 21g is common (31/2 mm). 
     Also printed on top face 12 are distance indicia 24a through 24m. With the exception of distance indicia 24c, indicia 24a through 24m are grouped in pairs so as to illustrate a range for a distance between two openings. For example, distance indicia 24a is 5/16&#34; wide, while distance indicia 24b is 1/8&#34; wide, and thus distance indicia 24a and 24b define a distance range from 5/16 &#34; to 1/8&#34;. Distance indicia 24c has a width of 1/8&#34;; distance indicia 24d and 24e define a distance range from 7/16&#34; to 1/2&#34;; distance indicia 24f and 24g define a distance range from 1/2&#34; to 9/16&#34;; distance indicia 24h and 24i define a distance range from 9/16&#34; to 5/8&#34;; distance 24j and 24k define a distance range from 5/8&#34; to 3/4&#34;, and distance indicia 24l and 24m define a distance range from 3/4&#34; to 7/8&#34;. 
     Adjacent the distance indicia and printed on top face 12, are opening size indicia 26a through 26g, each of which is indicative of the width or diameter of an opening into which protrusion 18 has been inserted. Each of opening indicia 26a and 26b is indicative of a 1/8&#34; hole. Each of opening size indicia 26 and 26d is indicative of a 3/16&#34; hole. Each of opening size indicia 26e and 26f is indicative of a 1/4&#34; hole. Opening size indicia 26g is indicative of a 5/16&#34; hole. 
     Also printed on top face 12 and adjacent the distance indicia are cane size indicia 28a through 28g, which correspond to indicia 21a through 21g, respectively. 
     The device 10 is employed for the selection of the proper cane to be used in caning an article of furniture. Protrusion 18 is inserted into an opening or hole in the article of furniture until one of the segments 19a through 19d fits snugly within the opening or hole. The indicia of the width or diameter of the hole or opening is then read, such indicia being one of indicia 22a, 22b, 22c or 22d. Then the distance indicia 24a through 24m are placed next to two adjacent holes in the furniture to determine an approximate distance between the holes. Once the width or diameter of a single hole and the approximate distance between two adjacent holes are determined, the indicia or the width or diameter of the hole and the indicia of the approximate distance between holes are matched with the appropriate cane size indicia to determine the size of the cane to be employed in the caning of the article of furniture. For example, if the hole has a width or diameter of 1/8&#34;, and the distance between the two adjacent holes is between 5/16&#34; and 3/8&#34;, the cane of the carriage size will be used. 
     Once the size of the cane is determined, one refers to one of the indicia 21a through 21g which refers to the correct cane size, and to one of the indentations 20a through 20g into which the correct cane will fit. Thus, if one needs to use cane of the carriage size, one refers to indicia 21a and indentation 20a, and attempts to insert cane into indentation 20a until one finds a cane which fits correctly into indentation 20a. When such a cane is found, then such cane may be used for the caning of a particular article of furniture. 
     Advantages of the present invention include the ability to determine the size of the cane to be employed in the caning of a particular article of furniture by using a single measuring device. By employing the device of the present invention, one can measure the width or diameter of the openings or holes in an article of furniture, and can determine the distance between two adjacent openings or holes with the same device. One may then use the device to determine the size of the cane to be employed, and can determine whether the cane is of the desired size. Thus, the device of the present invention enables one to save time and effort in determining the correct size of the cane to be used in a caning procedure. 
     It is to be understood, however, that the scope of the present invention is not to be limited to the specific embodiments described above. The invention may be practiced other than as particularly described and still be within the scope of the accompanying claims.
