Abstract

The invention pertains to a technology of manufacturing and assembling modular doors, which can be assembled on site, and specifically to modular doors, which can be assembled without a use of glue, by mortize and tenons.

Claims

1. A modular door comprising:

a. A first pre-manufactured stile having two ends and two sides, and provided with mortises along one of the sides,

b. a second pre-manufactured stile having two ends and two sides, and provided with mortises along one of the sides,

c. each stile comprises a slot for receiving rods, wherein this slot extends from the top of the stile to the bottom of the stile passing through the mortises of the stile,

d. a top and bottom pre-manufactured rail having two sides and two ends with a tenon provided at each end while each tenon has an opening to receive a locking rod, said stiles and rails for enclosing at least one door panel,

e. at least one intermediate pre-manufactured rail having two sides and two ends with a tenon provided at each end, and each tenon has an opening to receive a locking rod, positioned between the top rail and the bottom rail;

f. said rails being attached to the first and second stiles by means of mortises and tenons fastened in place by the set of rods; and

g. set of rods comprising;

locking rods of sufficient length to lock a single rail or a plurality of rails inside the corresponding stile;

said modular door can be assembled by insertion of the tenons of the rails into the corresponding mortises of the stiles followed by locking in place with the set of rods;

wherein upon the insertion of each tenon into the corresponding mortise of each stile the rod receiving slot and aperture are positioned offset one to another, wherein upon insertion of the locking rod, each tenon is tightly locked into its corresponding mortise.

2. The modular door of claim 1 wherein the set of rods, further comprises pushing rods, locking rods, or locking/pushing rods, wherein the pushing rods are provided to push the locking rods into the tenons of the intermediate rail, and the locking/pushing rods are provided to lock one rail and also to push another locking or pushing rod through the rod receiving channel of the stile.

3. The modular door of claim 1 or 2 wherein the set of rods further comprises an unlocking rod having a length equal to the height of the tenon of the corresponding rail to be unlocked, these unlocking rods are positioned between the pushing rods and the locking rods, and can be pushed into the tenon of the rail while removing the locking rod from the tenon to release the intermediate rail from the stile.

4. The modular door of claim 1 wherein the top and/or bottom rails further comprise a receiving member to receive an extension to the door having a corresponding mating member, this extension to the door can be decorative or functional.

5. A kit for assembling a modular door comprising:

a. two pre-manufactured stiles having two ends and two sides, provided with mortises along one of the sides and a rod receiving slot passing through said mortises;

b. at least three pre-manufactured rails having two sides and two ends with a tenon provided at each end wherein each tenon has a predrilled aperture to receive a locking rod;

c. at least one door panel; and

d. a set of rods to lock the rails to the stiles;

wherein said rod receiving slot and said predrilled aperture are offset to one another when said mortise and tenon are connected, creating a pulling force on the tenon and mortise when said rod is received in said slot and aperture;

said kit can be used to assemble a modular door which also can be disassembled.

6. The kit of claim 5 wherein the set of rods comprises two short locking rods of sufficient length to lock one rail to the stile and two long locking rods of sufficient length to lock at least two rails to the stile.

7. The kit of claim 5 wherein the set of rods comprises at least six locking rods to lock at least three rails to the stiles and at least two pushing rods to deliver the locking rods into the distant mortises of the stile.

8. The kit of claim 7 wherein the each stile has at least one locking rod and at least one pushing rod pre-inserted into its rod receiving slot proximate the mortise, distant from one of the ends of the stile.

9. The kit of claim 8 wherein an unlocking rod is positioned between the pre-inserted locking rod and pushing rod and a filler rod holds these rods in place during storage and delivery.

10. The kit of claim 5 further comprising at least one door extension member capable of being attached to at least one of the rails.

11. A method of assembling a modular door comprising:

a. pre-manufactured stiles having two ends and two sides, provided with mortises along one of the sides and rod receiving slots passing through said mortises,

b. pre-manufactured rails having two sides and two ends with a tenon provided at each end while each tenon has an opening to receive a locking rod;

wherein said rod receiving slot and said opening are offset to one another when said mortise and tenon are connected, creating a pulling force on the tenon and mortise when said rod is received in said rod receiving slot and said opening;

said method comprises insertion of the tenons of the rails into the mortises of the stiles, followed by insertion of the rods into rod receiving slots of the stiles and the opening of the tenons, thus locking the rails inside the stiles.

12. The method of claim 11, wherein at least one door panel is positioned between the rails and the stiles.

13. The method of claim 12 wherein the rods locking the rails inside each stile comprise at least two rods, said rods are selected from locking rods, pushing rods, filler rods, unlocking rods and combinations thereof.

14. A method of assembling a modular door comprising at least two pre-manufactured stiles having two ends and two sides, provided with mortises along one of the sides and rod receiving slots passing through said mortises and at least three pre-manufactured rails having two sides and two ends with a tenon provided at each end wherein each tenon has an opening to receive locking rod, using a set of rods, the method comprises:

a. insertion of a tenon of a first rail into the first mortise of the first stile;

b. locking said tenon in said mortise with a first dowel or set of rods;

c. positioning a first door panel adjoining said first rail and first stile;

d. insertion of a tenon of a second rail in to the second mortise of the first stile while locking the first door panel in place;

e. positioning a second door panel adjoining said second rail and the first stile;

f. insertion of a tenon of a third rail into the third mortise of the first stile while locking the second door panel in place;

g. locking the tenons of the second and the third rails in corresponding mortises by a set of rods;

h. positioning the second stile on the side of the rails distant from the first stile, wherein the tenons of the rails are inserted into the corresponding mortises of the second stile and the first and second door panels are also locked in place; and

i. locking the tenons of the rails in the second stile by the set of rods;

wherein said rod receiving slot and said opening are offset to one another when said mortise and tenon are connected, creating a pulling force on the tenon and mortise when said rod is received in said rod receiving slot and said opening;

wherein the assembled door, does not require a use of glue or additional bonding agents during the assembly process.

15. The method of claim 14 wherein the set of rods locking the rails inside each stile comprise at least one rod, and preferably more than two rods, wherein the rods are selected from locking rods, pushing rods, filler rods, unlocking rods and combinations thereof.

16. The method of claim 15 wherein a set of bushings further locks the rods inside the stiles.
