Abstract
Abstract A door or window arrangement whose frame encloses a pump. The door or window panel is equipped with a movable handle for manually opening and closing the opening in the frame by means of the panel. In the closed position of the panel, a pliable tube communicating with the pump is located between the panel and the frame, seals the frame opening, and locks the panel in place when the handle is moved on the panel. Coupling elements on the frame and panel are engaged in the closed position, the movement of the handle is transmitted to the coupling, and from the coupling to the pump which inflates the tube.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
274 words
A door or window arrangement comprising, in combination: a. frame means including a frame member, said frame means bounding an opening therethrough; b. a pump mounted on said frame means; c. closure means secured to said frame means for movement toward and away from a position in which said closure means obstructs said opening, said closure means including a closure member contiguously adjacent said frame member in said position of the closure means; d. a manually operable handle secured to said closure means for moving said closure means toward and away from said position thereof, said handle being movable on said closure means between two positions; e. a tubular, pliable sealing member interposed between said closure means and said frame means in said position of the closure means and communicating with said pump; f. cooperating coupling means on said frame member and on said closure member engaging each other in said position of said closure means; g. first motion traNsmitting means operatively interposed between said handle and said coupling means on said closure member; h. second motion transmitting means operatively interposed between said coupling means on said frame member and said pump for operating said pump when said coupling means are engaged and said handle is moved between said two positions thereof; and i. fluid sealed in said pump and said sealing member, said fluid expanding said sealing member and thereby locking said closure means to said frame means when said handle is moved from one of said two positions to the other position, and being withdrawn from said sealing member when said handle is moved from said other position to said one position.
Claim 2
Dependent Claim
274 words
A door or window arrangement comprising, in combination: a. frame means including a frame member, said frame means bounding an opening therethrough; b. a pump mounted on said frame means; c. closure means secured to said frame means for movement toward and away from a position in which said closure means obstructs said opening, said closure means including a closure member contiguously adjacent said frame member in said position of the closure means; d. a manually operable handle secured to said closure means for moving said closure means toward and away from said position thereof, said handle being movable on said closure means between two positions; e. a tubular, pliable sealing member interposed between said closure means and said frame means in said position of the closure means and communicating with said pump; f. cooperating coupling means on said frame member and on said closure member engaging each other in said position of said closure means; g. first motion traNsmitting means operatively interposed between said handle and said coupling means on said closure member; h. second motion transmitting means operatively interposed between said coupling means on said frame member and said pump for operating said pump when said coupling means are engaged and said handle is moved between said two positions thereof; and i. fluid sealed in said pump and said sealing member, said fluid expanding said sealing member and thereby locking said closure means to said frame means when said handle is moved from one of said two positions to the other position, and being withdrawn from said sealing member when said handle is moved from said other position to said one position.
Claim 3
Dependent Claim
46 words
An arrangement as set forth in claim 1, wherein said pump is mounted on said frame member, and said handle is mounted on said closure member, said frame member and said closure member being elongated in a common direction in said position of the closure means.
Claim 4
Dependent Claim
59 words
An arrangement as set forth in claim 2, wherein said motion transmitting means include two motion transmitting members respectively mounted on said frame member and on said closure member, and said coupling means connect said motion transmitting members for joint movement, the connected motion transmitting members moving in said common direction when said handle moves between said two positions.
Claim 5
Dependent Claim
42 words
An arrangement as set forth in claim 3, wherein said closure member and said frame member has respective longitudinal face portions opposite each other in said position of the closure means, said motion transmitting members being secured to said face portions respectively.
Claim 6
Dependent Claim
70 words
An arrangement as set forth in claim 4, further comprising a receptacle on said frame means, and a locking member movable on said closure means into and out of said receptacle transversely to the direction of movement of said closure means toward said position thereof, said first motion transmitting means including means for moving said locking member into said receptacle when said sealing member is being expanded by said fluid.
Claim 7
Dependent Claim
77 words
An arrangement as set forth in claim 4, wherein said coupling means include a coupling member fastened to one of said motion transmitting members for joint movement, the other motion transmitting member carrying receiving means for receiving said coupling member, the face portion associated with said one motion transmitting member carrying a fixed cover member, said coupling member projecting from said one motion transmitting member through a slot in said cover member toward the other face portion.
Claim 8
Dependent Claim
50 words
An arrangement as set forth in claim 6, wherein said coupling member is a roller rotatable on said one motion transmitting member, and said receiving means include a fork member having two tine portions, said roller being received between said tine portions in the engaged condition of said coupling means.
Claim 9
Dependent Claim
23 words
An arrangement as set forth in claim 4, the face portion of said frame member being formed with a recess receiving said pump.
Claim 10
Dependent Claim
92 words
An arrangement as set forth in claim 2, further comprising a resilient sealing strip mounted on said closure member, said sealing member being mounted on said frame member, and a flange member fixedly mounted on said frame member, said sealing strip, said sealing member, and said flange member being elongated in said common direction in said position of the closure means, said sealing strip being interposed between said sealing member and said flange member and held in pressure contact with said flange member when said sealing member is expanded by said fluid.
Claim 11
Dependent Claim
57 words
An arrangement as set forth in claim 1, wherein said handle is mounted on said closure means for rotation about an axis and moves angularly about said axis between said two positions thereof, said fluid being a liquid, said closure member moving away from said frame member when said closure means moves out of said position thereof.
