Abstract

The present disclosure relates to a book support and an attachment device that can be used to attach a book support to a shelf. A base plate is provided which rests on a shelf, and an upright extends from the shelf. Tongues are provided at each end of the base plate which are capable of clamping the shelf. The tongues extend from the base plate at an acute angle to the base plate, such that folding the tongues out to a direction perpendicular to the base plate makes the tongues urge inwards. The tongues may have a proximal portion and a distal portion wherein the distal portion is directed at an even more acute angle to the base plate. The attachment device can be attached to shelf boards having relatively wide manufacturing tolerances in terms of thickness.

Description

Book holder and attachment device

The present invention relates to a book holder comprising a bottom plate configured to rest on a frame, a plate-shaped upright member erected upward from the bottom plate, and an attachment device configured to secure the bottom plate to the frame. The invention further relates to an attachment device that can be integrated, such as with a book holder or with other devices, and to a system comprising a shelf and such attachment device.

The type of book holder originally mentioned is disclosed, for example, in US Pat. No. 7,767,037, which shows a sheet metal book holder having an attachment provided as a clamp configured to hook the frame. One problem associated with such book stands is how to enable them to be attached to the rack simply and reliably.

Accordingly, it is an object of the present invention to provide a book holder that can be attached to a rack simply and reliably by a user. This object is achieved by means of a book holder as defined in claim 1 of the patent application. More specifically, in the type of book holder originally mentioned, the attachment means is at each end of the bottom plate With a tongue. The tabs extend downwardly from the plane of the bottom plate and are resilient about an axis perpendicular to the plane of the uprights, and each tongue forms an acute angle with the bottom plate. This enables the frame to be sandwiched between the tabs where the clamping force is applied parallel to the plane of the bottom plate and the major surface of the frame on which the bottom plate rests. Compared to the clamp being used to hook the frame at one end of the bottom plate, the attachment becomes very reliable without the need to apply a large amount of force.

Each tongue may have a proximal tongue and a distal tongue, the proximal tongue and the bottom plate forming an angle in the range between 75 degrees and 85 degrees, and the distal tongue and the proximal end are formed at 95 degrees to An angle within the range between 105 degrees. This provides a book holder that is capable of accommodating a large mutual tolerance between the thickness of the shelf and the length of the tongue, since a thicker plate can simply bend the tongue a little more and The lower corner of the frame rests at the position of the distal end of the tongue.

At the corner between each tab and the bottom plate, an outwardly extending arc can be provided which connects the bottom plate to the tongue and provides a spring function which allows for greater tongue elasticity and reduces when the tongue is bent outwardly Any rise in the end of the bottom plate.

Each distal tongue can be generally parallel to the base and a corner can be formed between the proximal and distal ends of the tab.

Additionally, the end of each tab may include a downwardly directed tip that provides a grip to facilitate attachment of the book holder.

The book holder can be formed as a single piece with injection moulded plastic. A suitable material is polycarbonate (PC).

Attachment devices of the type defined above can be used in applications other than book stands and are generally configured to secure the floor to the rack. The attachment means includes a tongue at each end of the bottom plate, wherein the tongue is bent out from the plane of the bottom plate and is elastic about the axis around which the tongue is bent, and wherein each tongue is The bottom plate forms an acute angle. Such attachment means can thus be used for other purposes, in particular for storing different items.

Also contemplated is a combination of a shelf and an attachment device, wherein the attachment device is configured to secure the chassis to the shelf. The attachment means includes a tab at each end of the bottom plate, wherein the tab projects from the plane of the bottom plate and is resilient about the axis about which the tongue is bent. Each tongue forms an acute angle with the bottom plate and has a proximal tongue and a distal tongue, the proximal tongue and the bottom plate forming an angle in a range between 75 degrees and 95 degrees, and the distal tongue and the proximal end An angle in the range between 95 degrees and 105 degrees is formed, wherein when the attachment means is attached to the shelf, the distal end of each tongue rests on the corner of the panel.

Figure 10 schematically shows a prior art book holder.

The present invention relates, for example, to a book holder that is used to divide a bookcase into different sections and to support a book standing at the end of a row of books on the shelf. Figure 10 shows a book holder according to the aforementioned prior art document. The book holder includes an upright member 101 in the form of a plate that is erected from a bottom plate 103 for resting on a frame (not shown). A clamp 107 including an elastic tongue 105 is attached to the bottom plate 103 and is adapted to hook the frame to hold the book holder stationary relative to the frame. The book holder is made of a sheet metal as a single piece, and the sheet metal is stamped and bent into a desired shape. The present invention is directed to improving this type of book holder and further providing a fastening arrangement that is also well suited for attaching other devices to the frame.

Figure 1 shows a book stand 1 that has not been attached to a stand and a book stand that has been attached to the stand 9. The book holder 1 includes a bottom plate 5 and an upright member 3 in the form of a plate, and the upright member 3 is erected substantially from the bottom plate 5 in a vertical direction from the bottom plate 5. The book holder also includes first and second tabs 7, which are attached to the bottom plate 5 at the ends of the bottom plate 5.

Also shown in Fig. 1, when the book holder 1 is attached to the frame 9, the depth of the cover frame 9 is designed such that the elongated rectangular bottom plate 5 rests on the flat surface 11 of the frame, and the tongue 7 is made by the frame 9 keeps being caught in the tongue Between the sheets is connected to the edge surface 13 of the frame 9. The upright member 3 can be designed as a panel as shown, although other options are possible, such as, for example, a rectangular arc. While it is possible to laterally offset the uprights as viewed along the length of the bottom plate 5, as shown, the uprights 3 are vertically raised from the bottom plate 5 (and from the intermediate point of the bottom plate 5). As will be further described, the uprights can be replaced by other devices that perform different functions.

Figure 2 shows an enlarged portion of the book holder 1 of Figure 1 that has not been attached to the rack. As shown, the tongue includes a proximal end portion 17 that is attached to the bottom plate via a resilient portion 15, and the resilient portion 15 is formed to extend outwardly from a corner where the extension of the base plate 5 and the extension of the proximal tongue portion 17 meet The arc. As shown, the tab further includes a distal end portion 19 that is coupled to the proximal end portion. This configuration will be further described with reference to Figures 3 and 4, wherein Figure 3 shows a side view of a book holder that has not been attached to the rack, and Figure 4 shows an enlarged portion depicting the tongue of the book holder.

As shown in Fig. 4, the attachment means formed by the bottom plate 5 and the portions constituting the tongue can be made into a band having a uniform thickness along the tip from one tongue to the other through the bottom plate The path of the tip of the sheet extends, but a configuration in which the strip becomes narrower or wider along this path is also possible. The bottom plate 5 can be connected to the arcuate resilient portion 15 as shown, the arcuate resilient portion 15 is then connected to the proximal tongue portion 17, which in turn is connected to the distal tongue portion 19 at the corner 27. At the end of the distal tongue 19, a downwardly projecting tip 21 can be provided, which is easier to handle by the use of a finger, which facilitates the attachment of the book holder to the frame. When the book holder is attached to the top surface of the frame, the proximal tongue 17 extends downward, but in relation to An acute angle 23 of the bottom plate 5 is provided. This means that when attached to the frame 9 having a depth approximately equal to the length of the bottom plate 5, the tabs will have to be bent outwardly and will keep the frame sandwiched between the tabs. This bending occurs to a large extent in the elastic portion 15, but also to some extent in the proximal tongue 17. Furthermore, the distal tongue 19 is disposed inwardly at an angle 25 relative to the proximal tongue 17. This angle 25 is greater than 90 degrees, and is preferably in the range between 95 degrees and 105 degrees. In the case shown, the angle 25 is 100 degrees. As mentioned, the angle 23 between the bottom plate 5 and the proximal tongue is an acute angle, and preferably in the range between 75 and 85 degrees, and in the depicted case, the angle 23 is 80. degree.

FIG. 5 shows an example in which the book holder is attached to the frame 9. This shows the ability of the attachment device according to the invention to handle significant tolerances in the manufacture of the rack and/or attachment device. In the illustrated case, the frame 9 is close in thickness to its maximum tolerance relative to the attachment means. In the illustrated case, the tab is bent to the greatest extent outward, and the lower corner of the frame rests on the distal tongue, as shown in FIG. A corresponding case in which the frame is substantially thin is shown in Figs. 7 and 8, wherein Fig. 8 shows an enlarged portion of Fig. 7. As shown in these figures, the tabs are not as much bent outward, and the lower corners of the rack rest almost at the corners 27 between the proximal and distal ends of the tabs. As shown in Figures 5-8, this configuration of the proximal and distal tongues 19, 19 provides a simple and reliable attachment of the book holder to the holder, which can be allowed to have a relatively high thickness with respect to their thickness. tolerance.

Thus, thanks to the illustrated configuration, the bottom corner of the frame will rest at or near the corner between the proximal tongue 17 and the distal tongue 19. The position above depends on the thickness of the rack. This allows for relatively large tolerances on the thickness of the frame. A reliable and wobble-free attachment is still available. The angle 23 between the bottom plate 5 and the proximal portion 17 and the angle 25 between the proximal tongue 17 and the distal tongue 19 may be such that the distal tongue 19 is substantially parallel to the bottom plate at the unbent/relaxed position. 5.

In addition, thanks to the arrangement of the tongues at both ends of the bottom plate, the book holder disclosed herein is suitable for being manufactured by injection molding plastic, which is very cheap compared to the manufacture of a sheet metal book holder. of. For example, the support can be made of polycarbonate (PC), which also allows for the provision of a transparent book holder. Likewise, since the attachment device provides a secure connection to the shelf, it can attach the attachment device to the underside of the panel as shown in FIG. Even if it is assumed that this would make the device less useful as a book holder, it is possible to replace the uprights 3' with other means extending from the floor, for example, a row of hooks that can be used to carry other items under the frame side. This allows the attachment device to be used in other applications.

The present invention is not limited to the embodiments given above, and may be varied and changed in various ways within the scope of the appended claims. For example, although in the depicted embodiment the uprights are erected vertically from the floor, deviations from this direction are possible while maintaining the desired function.
