Essential parts of the present invention are described below.
A door frame system according to the present invention includes: a frame 200 serving as a body to which all essential parts are combined; a fixed bench 300 fit into a bench guide groove 201 and closely contacting with a glass pane G; a pressure bench 400 combined to the front surface of the fixed bench 300, sliding only in a horizontal direction, and strongly compressing the glass pane G; a compression rail 500 pushing the pressure bench in order to move it in the horizontal direction; a tightening bolt B/T lifting the compression rail upwardly; and a brush assembly 600 for preventing contaminant and serving as a weather strip.
As shown in
The upper space portion 200a of the frame 200 is in a trapezoidal form which is narrowed upwardly, and includes: inclined surfaces 200a and 200b formed on the wall surface thereof and getting gradually thicker downwardly; a flat guide surface 200b′ formed on the right inclined surface 200b with no structure; bench guides 202a and 202b formed at the center of the other inclined surface 200a facing the inclined surface 200b and having the guide groove 201. The fixed bench 300 is combined with the frame 200. A structure of the fixed bench 300 will be described in more detail.
The middle space portion 200b of the frame 200 includes: a support jaw 203 having a support recess 203a formed at one side of the upper surface thereof; screw holes 205a and 205b facing each other, pressure sustaining portions 206a and 206b formed at sides of the screw holes 205a and 205b and reinforced thick; and bolt holes 207a and 207b formed vertically, so that the tightening bolt B/T is fastened to the frame in such a way as to direct upwardly from the bottom.
Furthermore, the lower space portion 200c of the frame 200 includes: vertical wall surfaces 208a and 208b formed at both sides thereof; balance member guide grooves 209a and 209b formed at the central portions of the vertical wall surfaces 208a and 208b; and brush grooves 210a and 210b formed on the lower portions of the vertical wall surfaces 208a and 208b so that the brush assembly 600 is combined to the frame 200 through the brush grooves 210a and 210b. Moreover, a balance member 800 and a hinge link 900 are also combined to the frame 200 through the balance member guide grooves 209a and 209b.
Meanwhile, as shown in
To combine the fixed bench 300 to the frame 200, in a state where one end portion of the rail 304 is located at the front end portion of the bench guide groove 201 of the frame and the stable protrusion 306 is located at the support recess 203a, the worker applies some power to the fixed bench 300 so that the fixed bench 300 is stably pushed in the longitudinal direction so as to be combined to the frame 200.
Then, the rail 304 of the fixed bench 300 is fit to the bench guide groove 201 of the frame 200, and at the same time, the rear side 303 is in close contact with the front surface of the bench guides 202a and 202b, and the stable protrusion 306 formed on the base side 305 of the fixed bench 300 is seated on the support recess 203a formed on the support jaw 203b of the frame 200, whereby the fixed bench 300 can be combined integrally with the frame 200.
Moreover, the pressure bench 400 is combined to the front side of the fixed bench 300 in such a way as to face with the fixed bench 300, and at this time, a space Y for fitting the glass pane thereof is formed between the fixed bench 300 and the pressure bench 400. As shown in
Meanwhile, to combine the pressure bench 400 to the front side of the fixed bench 300, as shown in
Then, the base side 305 and the seating protrusion 307 of the fixed bench 300 are fit to the support portion 403 and the low horizontal jaw 405 of the pressure bench 400 in such a way that they are seated on the upper surfaces of the support portion 403 and the low jaw 405. And, at the same time, the friction portion 404 of the pressure bench 400 is fit to the bridge 204a of the frame 200 in such a way that the friction portion 404 is seated on the upper surface of the bridge 204a.
Continuously, the compression rail 500 is mounted between the guide surface 200b′ of the frame 200 and the rear side 406 of the pressure bench 400. At this time, as shown in
To combine the compression rail 500 to the frame 200, one end portion of the recess 507 is coincided with the holding portion 408 of the pressure bench 400, the second upper and lower friction surfaces 508a and 508b are coincided with the pressure portions 407a and 407b of the pressure bench 400, and the first upper and lower friction surfaces 504a and 504b of the rear side 503 are coincided with the front end portion of the guide surface 200b′ of the frame 200. After that, the compression rail 500 is pushed in a longitudinal direction slowly.
Then, the holding portion 408 and the restriction portion 409 of the pressure bench 400 are fit to the recess 507 and the restriction portion 506 of the compression rail 500, and at the same time, the first and second upper and lower friction surfaces 504a and 504b and 508a and 508b are combined to the guide surface 200b′ of the frame 200 and the pressure portions 407a and 407b of the pressure bench 400 in a closely contacting state.
Meanwhile, as shown in
The assembled frame 200 is combined with the glass pane G prepared on a table or a work stand.
To combine the glass pane G with the frame 200, the worker lifts up the frame 200 with his or her hand, fits it to an end portion of the glass pane G, and then, fastens them with the tightening bolt B/T, whereby the frame 200 is fixed to the glass pane G.
In other words, the worker lifts up the assembled frame 200, locates the end portion of the glass pane G in the space Y of the frame 200 for fitting the glass pane G, and then, turns the tightening bolt B/T in a locking direction.
When the tightening bolt B/T is turned in the locking direction, the compression rail 500 minutely moves the pressure bench 400 in a horizontal direction along the guide surface 200b′.
That is, five bolt holes 207a and 207b formed on the pressure sustaining portions 206a and 206b of the frame 200, which has a length corresponding to a width of a door, are formed at intervals of about 5-6 inches, and the tightening bolt B/T of 8 mm is fit into each bolt hole.
Each tightening bolt B/T is turned and locked while keeping its balance till it is inserted to a predetermined depth. An end portion of the tightening bolt B/T protrudes upwardly from the pressure sustaining portions 206a and 206b, and then, the locked tightening bolt B/T is idly rotated at the base side 501 of the compression rail 500 and pushes the compression rail 500 upwardly.
In addition, while the compression rail 500 is lifted upwardly by the tightening bolt B/T, the first upper and lower friction surfaces 504a and 504b of the rear side 503 are in close contact with the guide surface 200b′ of the frame 200, and the second upper and lower friction surfaces 508a and 508b of the opposed side are in close contact with the pressure portions 407a and 407b respectively formed at upper and lower portions of the rear side 406 of the pressure bench 400. So, the compression rail 500 slides upwardly in a state where it is in close contact with the pressure bench 400during it slides along the inclination angle of the guide surface 200b′, so that the compression rail 500 can firmly combine the frame 200 with the glass pane G by pushing the pressure bench 400 to the left in the drawing.
After the above operation, the balance member 800 is fit into the balance member guide grooves 209a and 209b formed on the vertical wall surface 208, and then, the hinge link 900 is combined to the balance member 800 with bolts. After that, end caps 700 are positioned at both ends of the frame 200 and fastened to the frame 200 with flat countersunk head screws 700a. By the above process, the door, which can be installed on a door frame of the building, is finished.
As described above, the present invention can be rapidly assembled within a short time period by only one worker since the fixed bench, the pressure bench, and the compression rail are firmly fastened in the upper space portion of the frame without separation.
Moreover, the present invention can be correctly assembled in a state where the frame and the glass pane keep a straight line condition without slant and provide an exact standard without transformation in length of the door, since the glass pane is fixed to the frame and fastened by the tightening bolts without vertical movement in a state where the fixed bench is fixed and only the pressure bench is horizontally movable.
Furthermore, the present invention can provide soundproof and mothproof effects and prevent incoming of dust or foreign matters to the inside of the building, since end portions of vertical wall surfaces of the frames installed at the top and bottom of the door are ventilated but combined with the brush assembly of thick fur to filter foreign matters.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
This application is a corresponding non-provisional application of U.S. Provisional Patent Application Ser. No. 60/798,076 for “Door Frame System” filed on May 5, 2006.
