ABSTRACT:
A security panel door of wooden construction, which is characterized by its ability to successfully meet established security test criteria that have been promulgated under existing official building codes, and a method of construction thereof. The subject security panel door embodies a pair of stiles, at least a top rail and a bottom rail, and at least one panel member. One of the longitudinally extending side edges of each of the pair of stiles has first joint means formed therein. The latter first joint means each include at least a first portion and a second portion, with the aforesaid first portion being larger than the aforesaid second portion in at least one dimension. Both the top rail and the bottom rail have a second joint means formed in one of the longitudinally extending side edges thereof. Each of the second joint means includes at least a first portion and a second portion, with the first portion being larger than the second portion in at least one dimension. The panel member is provided with third joint means formed in one pair of the longitudinally extending side edges thereof, and fourth joint means formed in the other pair of the longitudinally extending side edges thereof. The third joint means of the panel member is complementary in configuration to the configuration of the first joint means formed in the pair of stiles, and the fourth joint means is complementary in configuration to the configuration of the second joint means formed in the top and bottom rails. In accordance with the method of construction of the subject security panel door, the panel member is joined to the pair of stiles through the interconnection of the first and third joint means, and the panel member is joined to the top and bottom rails through the interconnection of the second and fourth joint means.
