Sliding wall mount for an easel

Abstract

A wall mounting device especially made for the 360 Degree Rotating Easel so that the easel can be mounted on a wall to save space and the need for a tripod-based floor or tabletop easel. The wall mount also enables variable height adjustments of the mounted work piece by means of a sliding inner arm encased by the wall mount chassis which then attaches to the wall and the easel.

Description

FIELD OF THE INVENTION

This application relates to a slide assembly especially as a wall mount for artist and display easels.

BACKGROUND OF THE INVENTION—PRIOR ART

I haven't found a wall mounted sliding mechanism especially designed for artist easels in the prior art. There are similar products which are quite common that use this sliding mechanism within a casing, but are quite a bit more complicated than my embodiment. The main disadvantage is the extra costs involved in a more complicated design.

The prior art I found relating to similar sliding mounting devices are by Ann Marie Reo, Chantal Louise Pittman, Brian Scott Jalufka—Wall mounting bracket U.S. Pat. No. 8,474,770 B2 (Jul. 2, 2013); Wen-Chun Chen, Ming-Chin Huang Wall mounting monitor bracket U.S. Pat. No. 7,448,584 B2 (Nov. 11, 2008); —Sliding Wall-Mount chassis CN102781195 B (Apr. 1, 2015); Mike David—Wall Bracket with integrated vertical lock US20090206214 A1 (Aug. 20, 2009); Zen Vic De—Support and Attachment Wall Mount assembly CA 2245809 A1 (Feb. 27, 2000); Manuel Saez—Mechanism for Positional Adjustment of an Attached Device US 20130248670 A1 (Sep. 26, 2013); William Dubon and Ronan Stephens—US Telescoping Slide Assembly U.S. Pat.

Trainor—Adjustable Support for Mirrors U.S. Pat. No. 2,569,622 (Oct. 2, 1951)—are all different in their scope, design and function from my embodiment and not especially designed for an artist easel. The art that Manual Saez teaches US 20130248670 A1 comes close to my embodiment, however I don't claim a “plurality of motion regulating devices”—specifically the gas spring shaft (60) and gas spring chamber (65) to adjust the position of the attached device. I just have pressure plates to fix the position of the easel arm. Saez's embodiment is designed for a computer display or flat screen monitor. My embodiment is especially designed to work with the 360 Degree Rotational Easel patented by the same inventor Robert A. Selwa U.S. Pat. No. 9,220,330 B, with issue date Dec. 29, 2015.

SUMMARY OF THE INVENTION

I have discovered a simple means for mounting an easel onto a wall or other accommodating surface with the additional feature of height adjustment. The setting of the desired height of the easel while attached to the sliding wall mount enables the artist to place the easel at a comfortable height for the artist, or presenter. The easel arm attaches to the wall mount assembly which is secured to a wall. This allows and enables the easel to be height adjusted. This embodiment not only allows height options for the artist or presenter for their ease, but also saves space and cost as now the tripod element is not necessary.

DETAILED DESCRIPTION OF THE INVENTION

Most every artist or presenter requires an easel to paint, draw, and display on, along with precious limited space in their studio. This wall mounting device to mount an easel to a mounting surface eliminates the need for a floor or tabletop easel and saves studio space. This device also allows the artist to position the height of the easel on the mounting surface (wall, door, etc. . . . ) and is especially designed as an accessory for the 360 Degree Rotational Easel, but not limited to that embodiment. The artist now has the option of having their rotating easel mount on the wall and easily adjust the height of the mounted easel for convenience and/or necessity.

The advantage of my embodiment over prior art is that this mechanism is specifically made to mate with a rotating or stationary easel and is thus designed toward this end. Sliding mechanisms are not new, nor is this encased sliding mechanism new, but using this embodiment to specifically mate and allow for a height adjustment with a rotating easel (although not limited to that easel) is novel. The canvas can now be adjusted to a height that is most comfortable for the artist, standing or sitting, and to accommodate the different sizes of their work piece. This embodiment can also be made of any suitable material—wood, plastic, metal, etc. . . . , and in any size. This embodiment is especially designed to be used with the “360 Degree Rotating Easel” patented by this inventor Robert A. Selwa U.S. Pat. No. 9,220,330 B, with issue date Dec. 29, 2015, but is not limited to this device.

I have simplified the necessary mechanisms here to their bare minimums. This embodiment is a sliding wall mount that is secured to a wall or other accommodating surface, and is also secured to an easel that attaches onto the wall mount chassis. The inner sliding bar is enclosed by the wall mount chassis, and then slid up and down inside the wall mount to vary the height adjustments of the rotating easel and is secured into position by pressure plates.

Operation—General

The wall mount (10) attaches to the wall by way of the mounting screws (24). The front clamping bar (42) of the rotating easel (or other unit) is secured onto the inner sliding bar (38) with machine screws (36). The inner sliding bar (38) is slid into the wall mount chassis (11) and then secured in place by machine screws (36) on the pressure plates (18). The rest of the easel (52) (or other device) attaches onto the locked in front clamping bar (42) by way of the hex bolt (48) on which the rotating easel arm (52) pivots. The felt pads (19) attached to the rear of the swivel front plate glides on the swivel rear plate (44) of the front clamping bar (42) for the rotating easel to function. The easel arm comprises a plurality of clamping arms for retaining the artist's canvas.

The height of the easel is adjusted by sliding the inner bar (38) up and down the wall mount chassis (11) to the desired height and secured in place by pressure using the machine screws (36) against the pressure plates (18). Pressure from the plates against the rear mount plate (28) holds the inner sliding bar (38) in place. FIGS. 8G & H show how the unit looks attached to a wall (50), or another mounting surface.

DETAILED DESCRIPTION OF THE SPECIFIC EMBODIMENTS

Description Of The First Embodiment—FIGS. 1A, 1B, 7B, 8D, 8E, 8G, 8H, & 8J—Wall Mount Chassis

The embodiment presented in FIGS. 1A & 7B is the wall mount chassis (11) which houses (FIGS. 5, 6, 7A, 8E, 8H, 8J) the sliding inner bar (38). The chassis (11) here in FIGS. 1B & 7B consists of three parts—the rear mount plate (28), inner guide bars (22), and the facing and securing bars (20) that are secured together with glue (40) and nails (17). Holes (12) are drilled through the rear mount plate (28) and then recessed drilled (30) so a wall mount screw (24) will set flush with the topside of the wall mount chassis (11). The mounting screws (24) then screw into the mounting through the rear mount plate (28) and into the mounting surface (50) securing the wall mount chassis (11) to the mounting surface (50).

Operation of the First Embodiment—FIGS. 1A, 1B, 7B, 8D, 8E, 8G, 8H, & 8J—Wall Mount Chassis

The wall mount chassis (11) is first secured by wall mount screws (24) screwed through the chassis (11) and into a mounting surface through the holes (12) shown in FIGS. 1A & 1B. This chassis (11) is then used as the guide for the sliding inner bar (38) to slide in and adjust the height of the easel.

Description of the Second Embodiment—FIGS. 2A, 2B, 2C, 3A, 4A, 4B, 5, 6, 7A, 7C, 7D, 8B, 8C, 8D, 8E, 8G, 8H, 8J—Inner Sliding Bar

The inner sliding bar (38) has four holes (12) drilled though the inner board (37) that correspond to the holes in the front clamping bar (42) of the easel. Insert nuts (16) are secured into these holes (12) to allow machine screws (36) to pass through. One set of screws (36) secures the front clamping bar (42) to the inner sliding bar (38) and the second set of screws (36) secures the inner sliding bar (38) onto the chassis (11) by way of the pressure plates. See FIGS. 2A, B & C; 3A, 4A, B; 5, 6, 7D, 8C, D, E, G, H, & J.

The reverse side of the inner sliding bar (38) (FIG. 7D) has felt pads (19) attached, and pressure plates (18). The pressure plates (18) are screwed in using the appropriate screws (13) and secured into place.

Operation of the Second Embodiment—FIGS. 2A, 2B, 2C, 3A, 4A, 4B, 5, 6, 7A, 7C, 7D, 8B, 8C, 8D, 8E, 8G, 8H, 8J—Inner Sliding Bar

The sliding inner bar (38) is encased and glides within the wall mount chassis (11) enclosure (see FIGS. 5, 6, 7A, 8D, E, G, H, J). The front clamping bar (42) attaches to the inner sliding bar (38) and is secured through the two outer holes (12) (FIGS. 3A, B, 4B) with the insert nuts (16) and machine screws (36) and flat washers (46) to tighten the two pieces (42 & 38) (see FIG. 3A) together.

The inner sliding bar (38) is secured onto the wall mount chassis (11) by way of the two inner holes (12) (see FIGS. 3A, B), insert nuts (16), flat washers (46), and machine screw (36). The longer machine screws (36) with flat washers (46) enter through the front clamping bar (42) and through the sliding inner bar (38) with the insert nuts (16), and then presses and bends out the pressure plates (18) until they press on the rear mounting plate (28) with sufficient pressure to secure the attached front clamping bar (42) (see FIG. 3B) of the easel arm (FIGS. 6, 8E & J) in place.

First, the wall mount chassis (11) is attached to the mounting surface. The front clamping bar (42) of the easel attaches to the inner sliding bar (38). The inner sliding bar (38) with the attached front clamping bar (42) slides into the chassis (11) and presses on the chassis' rear mounting plate (28) through the pressure plates (18) and machine screws (36), and secures the front clamping bar (42) to the wall or mounting surface (50). The sliding inner bar (38) travels up and down the chassis (11) and is secured into place by the pressure plates (18), and machine screws (36). The hex bolt (48) is recessed into the rear of the front clamping bar (42) and protrudes out the front to attach to the rotating arm (52) of the easel.

Construction of the Embodiments

To construct a wall mount chassis, cut ¼ inch plywood into a rectangle approximately 4 inches wide and 24 inches long. Next, rip a 1 inch×2 inch piece of plywood and cut into 24-inch-long pieces. Cut a 1″×2″ piece of wood the same length of 24″ and then rip in half. Glue and nail the pieces together as shown in FIGS. 1A & 1B. Drill small holes completely through the rear mounting plate about 1 inch from the ends for the mounting screws to fit through. Then recess the drill holes so the wall mount screw will fit flush into the rear backing plate.

The ⅜-inch-thick inner sliding bar (38) is cut wide enough to slip into the chassis' casing (see FIG. 2B). Next, drill four holes into the sliding inner bar to match up with the holes on the front clamping bar (42) and screw in the insert nuts (16).

Apply the adhesive backed felt pads to the rear side of the inner sliding bar. Cut, or have premade strips of metal that will act as a pressure plate and drill holes as shown in FIGS. 2B & 3A into each plate and into the rear of the sliding bar. Fasten the pressure plates with the screws.

CONCLUSION, RAMIFICATION, & SCOPE

The artist, presenter, or other user can now attach their easel to a wall or mounting surface to save space and the need for a standing easel tripod. The height of the attached easel can be varied by use of the inner sliding bar that is encased in and secured onto the wall mount. This wall mount is especially designed for an easel, or other similar mated device. The artist can now lower his canvas in case he wants to paint seated, or raise the canvas to paint standing. The artist can also secure the work piece to a height that accommodates the artist and the size of the work piece.

The ramifications and scope of this embodiment are that the unit can be mounted on any surface, and at any angle, and can be made any size, with any suitable material. The design can be modified, and constructed using different manufacturing techniques (such as injection molding, 3D printers, etc. . . . ). The addition and use of a telescoping arm could also be envisioned. While designed for use with the 360 Degree Rotational Easel, other uses can be found for this embodiment.
