BOOKSHELF AND BOOK SUPPORT 3 Sheets-Sheet 3 Filed July '2, 1966 A 7' TOEUEY United States Patent U.S. Cl. 211184 4 Claims ABSTRACT OF THE DISCLOSURE Apparatus including a slidably adjustable book support and means for mounting the book support in a bookshelf wherein the means for mounting the book support includes a channel with flanges secured to the undersurface of the bookshelf and a broad channel-shaped slider support adapted to be slidably received in the channel, the slider support having a pair of laterally extending flanges adapted to be received within the channel and to ride upon the upper surfaces of the flanges of the channel and the book support includes a book follower which depends from the slider support. In an alternative embodiment the book follower is pivotable between horizontal and vertical positions.
This invention relates to bookshelves and book supports, and more particularly relates to a bookshelf and hanging book support wherein the book support is .arranged for slidably adjustable positioning along the book shelf.
For purposes of this specification, the term bookshelf will refer to a horizontal surface adapted to and designed for supporting one or more books in an upright side-byside position, together with some overlying structure spaced upwardly from said horizontal surface, the two defining a space above said horizontal surface for the accommodation of the height, depth, and thickness of said books arranged side-by-side. Typically, but not necessarily, a top panel which may be the bottom of another bookshelf overlying the one in question or may be a top per se, will constitute the aforesaid overlying structure, and sides and a back panel will be provided to form a bookshelf enclosed on five of six sides. The term bookcase will refer to a plurality of bookshelves formed as a unit wherein the individual bookshelves are either arranged side-by-side, one above the other, or a combination thereof.
It is common to store less books on a bookshelf than will fully occupy the side-by-side shelf space. To prevent such books from falling over, one or more book supports are generally employed. A book support is any device or structure which can laterally support a book or books at any position along the shelf against toppling over sideways. Hanging book supports have been proposed in the past, but have been difiicult to slide from place to place along the shelf, have provided locking that marred or excessively wore the structure within which the book support slides, thus contributing to additional sliding difficulty, and have been unduly complex and accordingly expensive.
It is an object of the invention to provide an improved bookshelf and hanging book support.
Another object of the invention is to provide a slidably adjustable hanging book support having simplified but improved locking action to secure the book support in any position along the bookshelf against and in response to the pressure exerted thereon by one or more books laterally contacting the depending portion of the book support.
Another object of the invention is to provide locking action which does not mar the structure within which Patented Sept. 9, 1969 the book support slides, thereby preserving free sliding capability.
Another object of the invention is to provide a bookshelf and book support having the foregoing advantages combined with a capability of the depending portion of the book support being pivotable upwardly whenever desired out of the zone to be occupied by books.
These and other objects .and advantages of the invention will be more fully revealed during the description of two presently preferred but merely illustrative embodiments thereof, which are shown in the accompanying drawings, wherein:
FIG. 1 is an elevation view partially in section of a portion of a bookshelf and a first embodiment of .a hang ing book support engaged with said bookshelf;
FIG. 2 is a partial front view of the bookcase shown in FIG. 1 partially broken away to show the construction of the guide portion thereof which selectively slides and locks in the bookshelf;
FIG. 3 is a view of the book support shown in FIG. 2 taken along plane 3-3 therein;
FIG. 4 is a view corresponding to a portion of the view shown in FIG. 1, showing a second embodiment of the hanging book support engaged within the bookshelf;
FIG. 5 is a view corresponding to the view shown in FIG. 2, showing the second embodiment of the book support;
FIG. 6 is a detail view of a portion of the structure within which either embodiment of the book support hangs and slides, taken along plane 6-6 of FIG. 2; and
FIG. 7 is a view taken along plane 7-7 in FIG. 5.
Referring now to the figures, and particularly to FIGS. l-3 of the first embodiment, there is shown a bookshelf indicated generally at 10 which may be of conventional construction and may be fabricated in wood, metal, combinations thereof, or any other suitable bookshelf material. The bookshelf 10 is a single bookshelf unit forming .a part of a book case of several bookshelf units structurally combined, but the invention is equally applicable to single bookshelf units.
The bookshelf 10 includes a shelf 10a which extends horizontally and is adapted to support upright books which are arranged side-by-side in the usual fashion. The shelf 10a includes a groove 10b (FIG. 1) extending .along each of the left and right sides thereof as viewed from the front in FIG. 2. A pair of upright panels 12 are disposed at either side of shelf 10a, and a plurality of apertures 12a (FIG. 1) appear therein. Apertures 12a are aligned into two vertical rows, and are equispaced vertically. There are four such rows, two each in each of upright panels 12 in the facing surfaces thereof, and the apertures are aligned as between the upright panels 12. That is to say, they are arranged in horizontal coplanar groups of four, one each in each row. By this standard construction, the shelf 10a may be raised or lowered on the upright panels 12 to higher or lower horizontal planes by manipulation of hardware (not shown) which cooperates with apertures of each of the four rows and the grooves 10b at either side of shelf 10a.
The upright panels 12 extend from one bookshelf to another as a unitizing structure, i.e. they are common to several bookshelves counted both in the vertical and horizontal directions. A plurality of legs 13 extend below the lowermost shelf (not shown) of the bookcase to support the entire structure on a floor or the like. A back panel 14 is common to all the bookshelves 10 in a common vertical stack, and a top panel 15 is similarly common to all the uppermost bookshelves of the bookcase. It will be noted that the illustrated bookshelf 10 forms the uppermost bookshelf in a particular stack of the bookcase and consequently underlies the top panel 15 so that the bottom surface 15a of the top panel 15 forms the upper 3 extreme of the bookshelf 10. In lower bookshelves, the upper extreme of the particular bookshelf is defined by the lower surface of the shelf a of the bookshelf immediately above.
The bookshelf and book support according to the present invention includes a metal channel indicated generally at 20 recessed flushly into the undersurface a of the top panel 15, extending the entire length of the top panel 15 between upright panels 12, and a book support indicated generally at 30 carried for sliding movement within and depending from channel 20.
As may be seen in FIG. 1, channel has a crosssectional outline formed by an upper panel 20a terminated at either side by depending web 20b, 20c, formed with inwardly facing lower flanges 20d, 20e respectively. Flanges 20d, 20e are essentially parallel to panel 20a, and webs 20b, 200 are essentially perpendicular to panel 20a and flanges 20d, 202'. The opposed flanges 20d, 20e thus define a wide slot 20 giving access to the interior 20g of the channel 20. The entire channel 20 is recessed within a groove 15b in the lower surface 15a of top panel 15, of suflicient width and depth to fully accommodate the channel 20 so that the flanges 20d, 20e lie essentially flush with the lower surface 15a of top panel 15. As has already been pointed out, the illustrated bookshelf 10 happens to be the uppermost bookshelf in the bookcase. Lower bookshelves will have the shelf of an overlying bookshelf forming their upper extreme. In that case, the channel 20 will be recessed flushly in the manner just described into the lower surface of the shelf of the overlying bookshelf rather than into a top panel as illustrated. As may be seen in FIG. 6, at one end of channel 20 and at both ends if desired, is provided a short portion indicated generally at 20x thereof distinguished by the absence of flanges 20d and 20e. As will appear presently, this portion 20x is provided to allow the engagement or disengagement of individual book supports.
A book support of the first embodiment, shown at in FIGS. 1-3, includes a tilt-locking slider support indicated generally at 31, and a follower plate 32 secured to and depending therefrom. Slider support 31 includes a central body portion 31a which is generally broad channel shaped and slightly narrower in cross-section than opening 20 in the underside of channel 20, as may be seen in FIG. 1. Postion 31a is divided into a front portion 31b of deep cross-section and a rear portion 310 of shallower cross-section (FIG. 2). The book support 30 is employed so that rear portion 310 overlies the book leaning upon follower plate 32, for a purpose to be presently described. On either side of body portion 31a are lateral extensions or flanges 31d, 31c respectively, which are coplanar, and which extend along the entire length of the slider support body 31a. It will be appreciated that the slider support 31 may be stamped from a single piece of stock, or may otherwise be formed. Many materials may be employed, e.g. metals or plastics, but it is preferred that the slider support 31 be fabricated in aluminum or steel.
As may be seen in FIG. 1, the slider support 31 is slidably received within the channel 20. The interior 20g of the channel 20 is only slightly wider than the total width of the slider support 31 at the lateral extensions 31d, 31s, and is only slightly deeper than the thickness of lateral extensions 31d, 31e. In one useful dimensional embodiment the width of interior 20g is 1.12" while the width across lateral extensions 31d, 31e is 1.06", and the depth of interior 20g is 0.10" while the thickness of lateral extensions 31d, 31e is 0.06" and the length of lateral extensions is 1.50". As will appear presently, the closeness of the fit, and particularly the large ratio of the longitudinal dimension of extensions 31d, 31e to the clearance between the thickness of those extensions and the depth of interior 20g (in the example dimensions, a ratio of 1.50" to 0.04", or 37.5 :1) is important to the advantages of the invention. v
Follower plate 32 is generally rectangular in its main portion 32a although it may assume other shapes consistent with its purpose of meeting a book mutually broadside. The plate 32 is provided with a right angle flange 32b is welded to the deeper portion 31b of slider support 32b along its upper edge. Flange 31 at 32c and 32d (FIG. 3), but can be attached by other means, e.g. screws. The relation of plate 32 to slider support 31 is such that main plate portion 32a is perpendicular to the sliding axis of slider support 31, i.e. to the longitudinal axis of extensions 31d, 31e.
As previously mentioned, the book support 30 is preferably employed so that the shallower portion 310 of slider support 31 overlies the books being laterally supported by book support 30. Since the lower extreme of slider support 31 at portion 31c is essentially flush with channel 20 as well as the underside 15a of top panel 15, an especially tall book indicated at B may be accommodated thereunder. Since shelf 10a is adjustable, this can occur even with ordinary size books when other demands force the shelf height to be reduced as much as possible, as often occurs. Despite such accommodation, the leading edge 320 of flange 32b of follower plate 32 cannot dig into the undersurface 15a of panel 15, because the portion 31b to which it is secured depends below channel 20 and undersurface 15a. It should be understood that book support 30 is not necessarily directional, i.e. books can be supported laterally at either side thereof. But it is a feature that in the direction illustrated in FIG. 2 and just described, maximum shelf space is obtained for the supported books. As will be presently described, the book support 30 can be removed from the channel 20 for any purpose, including to reverse the direction of its slider support 31, so that this directional advantage may always be claimed by the user, or may be ignored when it is not necessary to utilize it.
When a normal book B is laterally supported by follower plate 32, or when an extra tall book B (equivalent to a normal book B in a smaller bookshelf space, as by raising shelf 10a) is so supported laterally, the whole book support 30 tends to turn clockwise (as viewed in FIG. 2), i.e. away from the book and with reference to slider support 31 as a pivot member. The amount of such turning is determined by the longitudinal dimension of lateral extensions 31d, 31c and the degree of vertical looseness thereof in channel 20. That is to say, the relatively rigid support 30 will turn until the forward ends 31 of extensions 31d, 31e contact the undersurface of top panel 20a of channel 20 and the rear ends 31g of extensions 31d, 31c contact the upper surfaces of flanges 20d, 20:: of channel 20. A problem exists, in that too much turning causes secure locking of slider support 31 within channel 20 but also causes marring of the interior surfaces of channel 20, which marring soon leads to sticking of slider support 31 within channel 20 when an attempt is made to slide it freely, as to reposition it along channel 20. On the other hand, if very little turning occurs, locking will not take place, and the books will not be supported laterally in place.
It has been found that the particular channel and slider support arrangement of the present invention effectively accomplishes the desired locking, while avoiding marring. This is so primarily because of the parallel relation between four planes: the undersurface of panel 20a of channel 20, the upper surfaces of lateral extensions 31d, 3le, the upper surfaces of channel flanges 20d, 202, and the undersurfaces of lateral extensions 31d, 31c; taken together with the aforesaid high ratio of length to vertical looseness of lateral extensions 310', 31:; within channel 20. The high ratio directly limits the degree of turning, while the planar character of all the contacting surfaces reduces the amount of high pressure contacting, i.e. distributes the force more broadly to prevent local diggingin and consequent marring. The result is that secure locking is achieved without lateral movement of slider 31 within channel 20 away from the books B before locking This lateral movement allows books to lean, and it is considered very desirable in the art to eliminate it. At the same time, the result is that marring does not occur, so that the book supports 30 remain easy to slide along the channels when they are not turned to their locking position.
In some applications, for example where very heavy books are supported in large numbers, or where children can be expected to abuse the device, it is advantageous to extrude or otherwise place a thin nylon or other selflu'bricating solid substance along either the interior of channel 20, or along lateral extensions 20d, 20e, or along both. With such provision, even unusually heavy torque loads at slider 31 will not prevent free siding of the support under unloaded conditions.
Referring now to FIGS, 4, 5 and 7, there is shown a second embodiment of the book support 30. In this embodiment, the slider support 31 includes spaced, coplanar lateral extensions 31d, 31a of a central body portion 31a, as in the first embodiment. The relation of extensions 31d, 31a to the channel 20, and all the locking and sliding attributes are the same as has already been described. However the slider support body 31a has been modified to accommodate a pivotable follower rod 35. Body 3111 is of depth intermediate that of portions 31b and 310 of the first embodiment, i.e. it extends but slightly below channel 20 and undersurface 15a of panel 15. A lateral slot 31h appears centrally in body 31a, and forward and rear of slot 31h (FIGS. 5 and 7) are depending webs 311' and 31 which are edge welded or otherwise joined to the undersurface of body 31a at 31k, 31m.
As may best be seen in FIG. 4, webs 31i, 31 are rectangular and are joined to body 31a at one extreme end of the upper major edge, so that a pair of free ends 31p, 31q extend under panel 15 toward the rear portion of the bookshelf, i.e. toward rear panel 14. A pivot pin 31r is carried between webs 31i, 31 immediately under the connection of the webs to the body 31a, i.e. between and below extensions 31d, 31e. Pin 311' is secured at either end by caps 31s, which may be formed by riveting. Follower rod 35 includes an aperture 35a at its upper end which receives the portion of pin 31r between webs 31i, 31 so that rod 35 is pivotable on pin 31r. Directly under pin 31:, on each of webs 311', 31 is a detent 311, 31u, which cooperates with a depression 35b, 350 on either side of rod 35 to retain the rod 35 in the vertical position shown in full outline in FIG. 4. A second pair of detents 31w, 31x appear in webs 31i, 31j near ends 31p, 31: facing one another, so as to engage the underside of rod 35 when it is in the horizontal position shown in broken outline in FIG. 4, and hold it there. The pivoting between the two positions, as desired, is manually accomplished. The slot 31h accommodates the upper extreme end of rod 35 when the rod is in the vertical, full outline, position.
The second embodiment of the invention thus offers a follower in the form of rod 35, that can be pivoted up to the horizontal position when not in use, or can be pivoted down to the vertical position to laterally support a book or books. This convenience allows a greater number of book supports 30 to be normally carried by a single channel 20, and kept horizontally out of the way until needed. This obviates the storage problem for non-used supports 30. As has already been mentioned, the support 30 of the second embodiment otherwise slides and locks in the manner of the first embodiment.
In FIG. 6 is shown an end portion 20x of channel 20, adjacent a side panel 12 of the bookshelf. It will be noted that the flanges 20d, 20a thereof have been removed for a distance slightly greater than the longitudinal dimension of lateral extensions 31a, 31e of either embodiment of slider follower 31. The book support 30 can thereby be inserted into or extracted from engagement within channel 20 at that point. If desired, a similar provision may be made at the other extreme of channel 20, i.e. adjacent the other side panel 12 (not shown). Book supports 30 may thereby be added or removed as desired, from shelf to shelf, etc., as needed. When a reversal of a support 30 is desired, as aforesaid, it may be accomplished by sliding it to and out of end 20x.
The depending book support and cooperating parts in the bookshelf proper according to the invention is now seen to provide a pleasing appearance, secure locking, freedom from marring and sticking, maximum shelf space utilization both in height and width thereof, easy addition and removal, and in the second embodiment, easy and attractive storage within the bookshelf itself by virtue of the pivoting feature.
The invention has been described by reference to two preferred but merely illustrative embodiments thereof. Many other variations in form and arrangement of parts can, as will be apparent to those skilled in the art be practiced within the scope of the invention.
