Abstract
Abstract A fence structure is disclosed in which rectangular panels are removably mounted on tracks between vertical upright posts. The tops of the panels overlap and interlock in such a way that an entire section of panels is secured by locking in place a single panel. Means are provided for maintaining the panels in a partially raised position or they can be completely removed from between the vertical posts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
A fence structure comprising pairs of spaced, vertical posts with a flat rectangular panel having a top, bottom and two opposing vertical sides removably mounted vertically between each adjacent pair of said posts; the opposing sides of said posts having vertical slots running substantially the length thereof and adapted to receive guide members mounted on opposing vertical sides of each of said panels; the top, horizontal side of each of said panels extending horizontally beyond the vertical sides of the panel to engage and interlock respectively with the corresponding top extension of each adjacent panels so as to form a continuous interlocking means extending across the entire top of the fence structure for preventing any panel from being raised until the panel adjacent on one side thereof whose top is in overlapping engagement with the extending top thereof is first raised, each of said vertical posts having an open slotted portion at its top which accommodates the overlapping and interlocking portions of said extending top sides and stop means mounted on one vertical side of each panel which engage the adjacent side of one post to maintain said panel in a raised position once it has been raised by sliding between the posts.
Claim 2
Dependent Claim
203 words
A fence structure comprising pairs of spaced, vertical posts with a flat rectangular panel having a top, bottom and two opposing vertical sides removably mounted vertically between each adjacent pair of said posts; the opposing sides of said posts having vertical slots running substantially the length thereof and adapted to receive guide members mounted on opposing vertical sides of each of said panels; the top, horizontal side of each of said panels extending horizontally beyond the vertical sides of the panel to engage and interlock respectively with the corresponding top extension of each adjacent panels so as to form a continuous interlocking means extending across the entire top of the fence structure for preventing any panel from being raised until the panel adjacent on one side thereof whose top is in overlapping engagement with the extending top thereof is first raised, each of said vertical posts having an open slotted portion at its top which accommodates the overlapping and interlocking portions of said extending top sides and stop means mounted on one vertical side of each panel which engage the adjacent side of one post to maintain said panel in a raised position once it has been raised by sliding between the posts.
Claim 3
Dependent Claim
14 words
The fence structure of claim 1 wherein said posts are of rectangular cross section.
Claim 4
Dependent Claim
15 words
The fence structure of claim 1 wherein said vertical slots are of "T" cross section.
Claim 5
Dependent Claim
22 words
The fence structure of claim 1 wherein said guide means are roller guides which engage the opposing sides of said vertical slots.
Claim 6
Dependent Claim
117 words
The fence structure of claim 1 wherein one of the extending top sides of each of said panels respectively overlaps the extending top side of the adjacent panel and the other extending top side of the panel is overlapped by the extending top side of the panel adjacent thereto, at least one panel in said fence structure having neither of its extending top members overlapped by an adjacent top member and secured by a removable pin which passes through the open slotted top portion of the last post in horizontal engagement with the extending top side of the panel which is disposed within said slotted top portion of the post to prevent the panel from being raised.
Claim 7
Dependent Claim
25 words
The fence structure of claim 5 wherein said panel whose top extensions are not overlapped is the last panel at one end of the structure.
