Description

BACKGROUND OF THE INVENTION

The present invention relates to lock installation training and, more particularly, to a door and frame with replaceable sections for hardware and lock installation practice.

Currently there is no way to effectively practice installing door hardware in a lab environment that simulates real world door and frame applications. This means that training is largely done in the field in an apprenticeship model, rather than a controlled predictable classroom model in which the order and type training is determined ahead of time, and a trainer is able to verify and certify mastery of a skill.

The best current alternative is to install locks on the cheapest door possible to minimize expenses, and install locks in as many configurations as possible before the door cannot be drilled anymore. Then the door and/or frame is replaced and discarded. The other option is to have a technician apprentice in the field working on real doors. This is often more difficult because there is not a controlled environment, and the workflow dictates the flow of training and topics covered.

As can be seen, there is a need for a door and frame made for practicing installation of lock hardware.

SUMMARY OF THE INVENTION

In one aspect of the present invention, a training aid comprises: a door comprising a front surface, a rear surface and an edge comprising a top, a bottom, a first side and a second side, wherein a first cut out is formed at the edge; a first bracket secured to the door adjacent to the first cut out; and a first door insert disposed within the first cut out and secured to the first bracket by a fastener.

These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

The present invention includes a door and frame with replaceable cutouts to practice installing locks and door hardware. This door and frame allows for a trainee to repeatedly install door hardware and locks from scratch, without damaging a door or frame. When the work is done the section of the door or frame is simply replaced with a new insert, and the installation process can be repeated indefinitely.

Referring to FIGS. 1 through 8, the present invention includes a training aid. The training aid includes a door 10 having a front surface 12, a rear surface 14 and an edge having a top, a bottom, a first side and a second side. A first cutout 10a is formed at the edge. A first bracket 18, 20 is secured to the door 10 adjacent to the first cutout 10a. A first door insert 16 is disposed within the first cutout 10a and is secured to the first bracket by fasteners 46, such as bolts and screws.

The present invention further includes a door frame 51. The door frame 51 includes a first upright 52, a second upright 54, 56, 58 and a top 60, 62, 64, 66, 68. The door 10 is connected to the first upright 52 by hinges. The door frame 51 may include permanently affixed sections that may be welded onto frame reinforcements, as well as sections that are removable and attached via fasteners 74, such as bolts and screws. When the permanently affixed sections and removable sections are mounted, the present invention may create a functional hollow metal double rabbit style frame.

The door 10 may include a wood door or a reinforced hollow metal door with reinforced cutouts strategically placed where industry standard hardware is typically mounted. The door 10 has reinforced mounting brackets on the surface that allow the door to hold the replaceable door inserts. In certain embodiments, the door 10 may include the first cutout 10a at the second side, a second cutout 10b out at the top, a third cutout 10c at the first side, a fourth cutout 10d at the bottom, and a fifth cutout 10e out at the top. The door inserts include an outer edge that corresponds with the inner edge of the cutouts. For example, the door inserts and the cutouts may be square or rectangular shaped. The first door insert 16 fits within the first cutout 10a, a second door insert 28 fits within the second cutout 10b, a third door insert 22 fits within the third cutout 10c, a fourth door insert 40 fits within the fourth cutout 10d and a fifth door insert 34 fits within the fifth cutout 10e.

As mentioned above, brackets may be used to releasably secure the door inserts within the cutouts. The first bracket 18, 20 may include a first pair of L-shaped plates 18 fixedly secured to the front surface 12 of the door 10 and a second pair of L-shaped plates 20 fixedly secured to the rear surface 14 of the door. A second bracket 24, 26 may include a first pair of plates 24 fixedly secured to the front surface 12 of the door 10 and a second pair of plates 26 fixedly secured to the rear surface 14 of the door 10. The third bracket 30, 32 may include a first U-shaped plate 30 fixedly secured to the front surface 12 of the door 10 and a second U-shaped plate 32 fixedly secured to the rear surface 14 of the door 10. The fourth bracket 42, 44 may include a first U-shaped plate 42 releasably secured to the front surface 12 of the door 10 by fasteners 48, such as bolts and screws, running through openings formed in the first U-shaped plate 42 and through openings 50 formed through the front surface 12 of the door 10 and a second U-shaped plate 44 fixedly secured to the rear surface 14 of the door 10. The fifth bracket 36, 38 may include a first U-shaped plate 36 fixedly secured to the front surface 12 of the door 10 and a second U-shaped plate 38 fixedly secured to the rear surface 14 of the door 10. Each of the plates of the brackets include a portion extending beyond an inner edge of the respective cut outs. The portion includes openings sized to receive fasteners 46 therethrough. The fasteners 46 are driven through the openings of the brackets and into the inserts, thereby releasably securing the inserts within the cutouts.

As mentioned above, the door frame 51 may include permanently affixed portions and removeable portions. In certain embodiments, the second upright may include a lower member 54, an upper member 58 and a detachable member 56 secured to the upper member and the lower member by fasteners 74. The lower member 54 and the upper member 58 may be permanently affixed. The detachable member 56 aligns with with the first cut out. The top of the door frame 51 may include a first corner 60, a first detachable member 66, a middle member 62, a second detachable member 68, and a second corner 64. The first corner 60, the middle member 62 and the second corner 64 may be permanently affixed. The first detachable member 66 may be secured to the first corner 60 and the middle member 62 by fasteners 74. The second detachable member 72 may be secured to the middle member 62 and the second corner 64 by fasteners 74. The first detachable member 66 may align with the fifth cutout and the second detachable member may align with the second cutout. In certain embodiments, the permanently affixed portions may each include tabs 70 protruding from ends, the tabs 70 having openings. The detachable members may each include openings 72 that align with the openings of the tabs 70. The fasteners 74 may run through the aligned openings, thereby releasably securing the detachable portions to the permanently affixed portions.

When the door and frame inserts are installed, these pieces allow for the installation of the door hardware to be mounted to the door inserts of the door, and function by locking and interacting with hardware mounted to the removable sections of the frame to simulate a working door and frame. Then the process is reversed and the door hardware is removed. The screws securing the inserts to the door are removed from the mounting brackets, and the removable door inserts are replaced with new sections. The removable frame portions can then be removed by removing the screws that hold it to the frame through the mounting tabs, and these sections of the frame can be replaced. Then, the process of reinstalling door hardware can be repeated as desired.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
