Computer keyboard tray

Abstract

A keyboard tray assembly includes a tray having a front end and a bottom wall with an upper surface. A front wall is rotatably secured to the front end of the tray by a first hinge. The front wall is rotatable between an up position and a down position. The first hinge has first and second hinge members which are rotatably coupled together about a pivot point. The first hinge member is secured to the tray and the second hinge member is secured to the front wall. The first hinge is shaped to position the pivot point adjacent to the front end of the tray below the upper surface of the bottom wall and within a first recess in the front wall. This allows the front wall to pivot in close relationship to the front end of the tray.

Description

BACKGROUND

Some desks are specifically designed for computers and include a shallow sliding tray or drawer for storing the keyboard below the desktop. The tray is designed to slide outwardly to a position in front of the desk so that the user can access the keyboard when operating the computer. Some trays contain a pivoting front wall that can be raised into an upright position or lowered into a horizontal position. When the tray is positioned under the desktop for storing the keyboard, the front wall is typically pivoted into the upright position to hide the keyboard. When the tray is slid outwardly into a position in front of the desk for accessing the keyboard, the front wall is typically pivoted downwardly into the horizontal position in front of the keyboard to act as a handrest.

FIGS. 1 and 2 depict the typical prior art method of pivotably securing a front wall to a keyboard tray. Keyboard tray 100 includes a bottom wall 102 and three side walls 108. The front wall 106 is mounted to the bottom wall 102 of tray 100 with a pair of standard hinges 104. The hinges 104 are usually spaced apart from each other. One hinge member 104a of each hinge 104 is mounted to the upper surface of bottom wall 102 and the other hinge member 104b is mounted to the inner surface of front wall 106. FIG. 1 depicts front wall 106 in an upright position and FIG. 2 depicts front wall 106 in a horizontal position. A drawback of this design is that a large gap 110 extends between the front wall 106 and the bottom wall 102 due to the location of the pivot 104c of the hinges 104. This gap 110 is usually large enough such that objects the size of a pencil can fall through the gap 110 which can be a nuisance to the user. In addition, as can be seen in FIG. 2, exposed edges of pivot 104c as well as hinge members 104a/104b on the bottom wall 102 and the front wall 106 are in areas that could cause injury to the user of the computer by scraping or scratching the user's hands or wrists.

SUMMARY OF THE INVENTION

The present invention is directed to a keyboard tray assembly which addresses the problems in the prior art discussed above. The keyboard tray assembly of the present invention includes a tray having a front end and a bottom wall with an upper surface. A front wall is rotatably secured to the front end of the tray by a first hinge. The front wall is rotatable between an up position and a down position. The first hinge has first and second hinge members which are rotatably coupled together about a pivot point. The first hinge member is secured to the tray and the second hinge member is secured to the front wall. The first hinge is shaped to position the pivot point adjacent to the front end of the tray below the upper surface of the bottom wall and within a first recess in the front wall. This allows the front wall to pivot in close relationship to the front end of the tray, thereby minimizing the gap therebetween.

In preferred embodiments, the tray has a first side wall. The first hinge member has a mounting surface which is secured to the interior surface of the first side wall and the second hinge member has a mounting surface at a right angle to the mounting surface of the first hinge member which is secured to the interior surface of the front wall adjacent to the first recess. In addition, the first and second hinge members each have a pivot arm portion extending below the upper surface of the bottom wall into the first recess of the front wall. The arms are rotatably coupled together about the pivot point. The front end of the tray acts as a stop for the front wall when the front wall is lowered into the down position. A latching member latches the front wall in the up position and includes a magnet secured to the first side wall at the front end of the tray for magnetically engaging the second hinge member. In one preferred embodiment, the magnet is secured to the top of the first side wall. In another preferred embodiment, the magnet is secured within the front end of the first side wall.

Typically, the tray assembly includes a second side wall opposite to the first side wall and a second hinge spaced apart from the first hinge. The second hinge has first and second hinge members rotatably coupled together about a pivot point. The first hinge member of the second hinge is secured to the second side wall and the second hinge member of the second hinge is secured to the front wall. The second hinge is shaped to position the pivot point of the second hinge adjacent to the front end of the tray below the upper surface of the bottom wall and within a second recess in the front wall.

By mounting the first and second hinges to the side walls of the tray instead of to the bottom wall, there are no hinge members on the bottom wall of the tray on which the user can injure his/her hands or wrists. In addition, the second hinge members of the first and second hinges are secured to the front wall at locations beyond the effective work space of the user and, therefore, present little risk of injury. Finally, the pivot points are hidden within the recesses of the front wall.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 3-6, keyboard tray assembly 10 includes a tray 10a having a bottom wall 14 for supporting a keyboard (not shown), two side walls 18a/18b and a rear wall 20. Walls 18a, 18b and 20 keep the keyboard, accessories and writing supplies from sliding or rolling off bottom wall 14. Tray 10a includes two rail assemblies 44 mounted to the exterior surfaces of side walls 18a/18b for slidably mounting keyboard tray assembly 10 to a desk. A front wall 16 is pivotably mounted to the front 14b of tray 10a by a left hand hinge 36a and right hand hinge 36b. Hinges 36a/36b have pivot points 32 which are positioned within a pair of slotted recesses in front wall 16. Front wall 16 is pivotable between an upright position (FIG. 4) and a generally horizontal position (FIG. 5). When in the upright position, front wall 16 hides and prevents the contents of tray 10a from falling out. When front wall 16 is lowered into the generally horizontal position, the user can access the keyboard and also use front wall 16 as a handrest.

Hinges 36a and 36b are similar to each other, differing in that the hinges are mirror images of each other. Referring to FIGS. 7 and 8, each hinge 36a/36b includes a first hinge member 30a which is rotatably coupled to a second hinge member 30b by pivot point 32. Each first hinge member 30a is flat, planar and generally "L" shaped. First hinge member 30a has an elongate mounting portion 15a and a pivot arm portion 15b (FIGS. 5 and 6) extending downwardly from mounting portion 15a at a right angle. Each second hinge member 30b has a flat pivot arm portion 13b which is rotatably coupled to pivot portion 15b by pivot point 32 and a flat elongate mounting portion 13a extending perpendicularly from pivot arm portion 13b on one side. The pivot arm portions 13b/15b lie along parallel planes adjacent to each other. Mounting portion 13a is laterally offset from pivot arm portion 13b. In addition, mounting portion 13a is also perpendicularly oriented relative to mounting portion 15a so that mounting portions 13a and 15a can be mounted to surfaces that are at right angles to each other. Furthermore, mounting portions 13a/15a have mounting holes 34 formed therethrough.

The mounting portions 15a of the first hinge members 30a are mounted to the interior surfaces 19a/19b of side walls 18a/18b in an upright orientation with screws 26 extending through mounting holes 34 and into holes 26a within side walls 18a/18b (FIGS. 3-6). The mounting portions 13a of the second hinge members 30b are mounted to the interior surface 16a of front wall 16 in a flat manner offset from slotted recesses 28 with screws 26 extending through mounting holes 34 and into holes 26a within side walls 18a/18b. The mounting portions 13a are located adjacent to the outer side of slotted recesses 28 (closer to the ends of front wall 16). As a result, the first hinge members 30a are located on the inside facing each other and the second hinge members 30b are on the outside. The pivot arm portions 15b of the first hinge members 30a (FIGS. 3 and 6) extend perpendicularly downwardly from the mounting portions 15a in front of and adjacent to the front 14b of bottom wall 14, and into slotted recesses 28. The pivot arm portions 13b of the second hinge members 30b extend perpendicularly from the mounting portions 13a into the slotted recesses 28. The pivot arm portions 13b extend a short distance into slotted recesses 28 from the interior surface 16a of front wall 16. The pivot points 32 are positioned within slotted recesses 28 at a location below the upper surface 14a and in front of the front 14b of bottom wall 14.

Slotted recesses 28 extend through the interior surface 16a and through edge 16b of front wall 16. Each slotted recess 28 is sized to provide a sufficient amount of space around pivot arm portions 13b/15b to allow first hinge member 30a to pivot therein as well as to allow hinge member 30a to enter and exit slotted recess 28 (FIGS. 4-6). A radius 17 is formed on the inner edge of front wall 16 to further allow the front wall 16 to pivot closely to bottom wall 14.

A magnetic latch 40 for engaging the mounting portion 13a of the left hand hinge 36a is secured to the upper surface of side wall 18a. Referring to FIGS. 9 and 10, magnetic latch 40 includes a housing 41 with a magnet 42 protruding from the front end. Magnet 42 can be adjusted inwardly or outwardly by an adjusting screw 46a located at the rear end of housing 41. Once magnet 42 is in the proper position, nut 46b is tightened to lock magnet 42 in place. A post 48 extends downwardly from housing 41 for insertion into a hole in the top of side wall 18a. Post 48 includes ridges for locking post 48 therein within the hole. Although magnetic latch 40 is shown to be secured to side wall 18a, alternatively, magnetic latch 40 can be secured to side wall 18b. In addition, if desired, a magnetic latch 40 can be mounted to each side wall 18a/18b.

In use, the rail assemblies 44 of keyboard tray assembly 10 are engaged with mating slide rails mounted within a desk for slidably mounting keyboard tray assembly 10 thereto. The keyboard, mouse and mouse pad of a computer, as well as writing supplies, can then be stored within tray 10a. When the computer is not being used, keyboard tray assembly 10 is slid into the desk for storage. Front wall 16 is pivoted into the upright position (FIG. 4) to conceal the keyboard. The mounting portion 13a of hinge 36a engages the magnet 42 of magnetic latch 40 to latch front wall 16 in the upright position.

In order to operate the keyboard, the keyboard tray assembly 10 is slid outwardly from the desk to a position in front of the desk. The front wall 16 is then pivoted downwardly into a generally horizontal position as seen in FIG. 5 so that the user can access the keyboard. The edge 16b of front wall 16 engages the front 14b of bottom wall 14 which acts as a stop for preventing further downward movement of front wall 16. Once front wall 16 is in the lowered or down position, front wall 16 can act as a hand rest for the user when working on the keyboard. Although front wall 16 is shown to be in a horizontal position, front wall 16 may have a slight downward angle.

By positioning the pivot points 32 of hinges 36a/36b within the slotted recesses 28 of front wall 16 below the upper surface of bottom wall 14, the front wall 16 can be positioned closely to bottom wall 14 such that there is a minimal gap therebetween. The gap between front wall 16 and bottom wall 14 is small enough such that most objects stored in tray 10a will not fall through the gap. The slotted recesses 28 also hide the pivot points 32 from view. Securing the mounting portions 15a of the first hinge members 30a to the inner surfaces 19a/19b of side walls 18a/18b eliminates the existence of hinge surfaces on the upper surface 14a of bottom wall 14 and positions mounting portions 15a in a location that will not likely cause injury to the user. In addition, pivotably coupling the mounting portions 13a of the second hinge members 30b to the outside of the first hinge members 30a positions the mounting portions 13a in a location that will also not likely cause injury to the user. The reason is that the mounting portions 13a are located beyond the usable work area of tray 10a in front of side walls 18a/18b (FIG. 6).

The upright orientation of mounting portions 15a also increases the strength of hinges 36a/36b. Mounting portions 15a have a higher moment of inertia and as a result, are stronger when mounted in the upright orientation against side walls 18a/18b instead of being mounted flat onto bottom wall 14. Additionally, the forces exerted on mounting portions 15a tend to be shear forces which are perpendicular to the axes of screws 26. If mounting portions 15a were mounted in a flat manner onto bottom wall 14, the forces which would be exerted on mounting portions 15a would be tensile forces pulling on screws 26 which is undesirable.

In one preferred embodiment, keyboard tray assembly 10 has a front wall 16 that is about 3 inches high.times.3/4 inch thick. Recesses 28 within front wall 16 are about 11/4 inches long.times.1/4 inch wide.times.1/2 inch deep and extend through the edge 16b of front wall 16. Side walls 18a/18b are about 7/8 inches high and 1 inch wide. The mounting portion 15a of each hinge member 30a is about 21/2 inches long.times.1/2 inch high. The pivot arm portion 15b extends downwardly from the mounting portion 15a about 1/2 inch. The mounting portion 13a of each hinge member 30b is about 21/4 inches long.times.5/8 inches wide. The pivot portion 13b extends at a right angle downwardly from mounting portion 13a about 1/2 inch and is 1/2 inch wide. The pivot point 32 is about 5/16 inch below mounting portion 13a. The proximal end of mounting portion 13a is located at a position parallel to pivot point 32 so as not to interfere with the front 14b of bottom wall 14 during rotation (FIGS. 4 and 5). Pivot point 32 is formed by a 1/8 inch diameter pin extending through pivot arm portions 13b/15b. Mounting holes 34 are countersunk within mounting portions 13a/15a so that the heads of screws 26 do not protrude above mounting surfaces 13a/15a.

Hinges 36a/36b are preferably made from steel about 0.075 inches thick but alternatively can be made from other suitable materials such as brass or be of other thicknesses. Although mounting portions 13a are preferably elongated for engagement with the magnet 42 of magnetic latch 40, alternatively, mounting portions 13a can be shortened and a separate metallic plate secured to the interior surface 16a of front wall 16 for engagement with magnetic latch 40. Bottom wall 14, side walls 18a/18b, rear wall 20 and front wall 16 are preferably made of wood, but alternatively, other suitable materials can be used such as plastics, metals or composites. If bottom wall 14 is made of a material that is thin, a thickened lip can be formed at the front end 14b of front wall 14 for engaging the edge 16b of front wall 16.

Referring to FIGS. 9-11, keyboard tray assembly 50 is another preferred keyboard tray assembly which differs from keyboard tray assembly 10 in that hinges 22a and 22b have a second hinge member 38 with a short mounting portion 13a. Instead of employing magnetic latch 40, a pair of magnets 24 are secured within holes 24a in the ends of side walls 18a and 18b for magnetically engaging both second hinge members 38. Side walls 18a and 18b are set back a slight distance from the front 14b of bottom wall 14 so that the magnets 24 can protrude from side walls 18a/18b. Since magnets 24 are positioned closer to pivot points 32 than the magnetic latch 40 of keyboard tray assembly 10, two magnets 24 are preferably employed to provide sufficient holding power.

While this invention has been particularly shown and described with references to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

For example, although keyboard tray assemblies 10 and 50 have been shown to include magnetic latches, alternatively, suitable mechanical latches can be employed. In addition, although hinges 36a/36b and 22a/22b have been shown to mount to surfaces 16a and 19a/19b, alternatively the hinges can be recessed into side walls 18a/18b and front wall 16. Furthermore, although specific dimensions have been described, such dimensions can be varied to suit particular applications. Finally, the first hinge members 30a can be pivotably coupled directly to front wall 16 within slotted recesses 28 by pivot pins.
