Description

Desk top plate with tempered glass {Desk plate with tempered glass}

The present invention relates to a desk used in a school or academy, and more particularly, to a desk top plate covered with tempered glass to prevent scratches on the top plate.

In general, desks used in schools or academies have a structure in which a top plate made of wood or synthetic resin is attached to a steel frame. The wood top plate is easy to process and helps to create a study atmosphere by giving a warm aesthetic feeling, but has a problem of being easily damaged by graffiti or scratches.

As a prior art related to this, a 'glass fixing structure to a desk top plate' is disclosed in Patent Document 1, which consists of a structure in which tempered glass is fixed using brackets at the corners of the top plate, and 'a structure in which tempered glass is attached to a student desk top plate' in Patent Document 2 consists of a structure in which tempered glass is fixed using edge molding, and 'tempered glass school desk' in Patent Document 3 also consists of a structure in which tempered glass is fixed to the top plate using edge molding.

On the other hand, the present applicant has developed a 'desk having a tempered glass top plate' of Patent Document 4, which is made of a method of fixing the tempered glass to a support plate injection-molded with synthetic resin in an interference fit method.

In the case of the above-described Patent Document 1, the appearance of the desk is not good due to the bracket, and when the bracket is damaged, there is a risk that the fixed tempered glass is easily separated from the top plate, and there is a gap between the side of the tempered glass and the desk top plate.

In addition, the method of fixing the tempered glass using edge molding such as in Patent Document 2 or Patent Document 3 has the disadvantage that the entire circumference of the upper plate is surrounded by the edge molding, so steps are formed vertically and the aesthetic appearance is deteriorated.

So, the present applicant developed the 'desk top plate covered with tempered glass' of Patent Document 5, but in Patent Document 5, an opening was formed on one side rather than an interference fitting method like Patent Document 4, and the tempered glass was slidably coupled, and then a finishing member was inserted and a fixing screw was fastened at the bottom. However, the border between the top plate and the finishing member exists on one side of the circumference of the top plate, so the aesthetics deteriorated, and the disadvantage is that it can be easily dismantled by loosening the screw. It is becoming.

Korean Patent Registration No. 10-0692259 (2007.03.02.) Korean Patent Publication No. 10-2008-0091698 (2008.10.14.) Korean Patent Registration No. 10-1409511 (2014.06.12.) Korean Patent Registration No. 10-1346589 (2013.12.24.) Korean Registered Patent No. 10-2112607 (registered on May 13, 2020)

The present invention has been devised to solve the above problems, and an object of the present invention is to make it possible to firmly place tempered glass on the top plate without unnecessarily increasing the thickness of the desk top plate or putting molding on the outside, not impairing the aesthetics of the desk top plate due to the tempered glass fixing structure in the form of a cut portion at the edge, and having a rigid structure that can be firmly fixed by inserting the tempered glass into the inside of the top plate without fastening screws, and which cannot be arbitrarily disassembled. We are providing a covered desk top.

In order to achieve the above object, the present invention is a desk top plate covered with tempered glass. The top plate has a rectangular shape, reinforcing ribs are formed at a predetermined height so that the tempered glass is placed inside the top plate, and a protruding frame lower than the reinforcing rib is formed on the periphery of the top plate. Elastic hooks having a predetermined width are provided at regular intervals on the protruding frame. Hook grooves into which the elastic hooks are inserted are formed at regular intervals on the inside of the side portions of the closing frame, and hook grooves are formed between the hook grooves to prevent the closing frame from being peeled off. Provided is a desk top plate covered with tempered glass.

According to the above-described embodiment of the present invention, when the tempered glass is placed on the upper plate and the finishing frame is pressed and inserted thereon, the elastic hook formed on the rim of the upper plate is caught in the hook groove formed inside the side part of the finishing frame, and at the same time, the protrusion formed inside the finishing frame is caught on the protruding frame outside the upper plate. Since it is fixed in a fitted state, the aesthetics of the top plate is excellent, and the tempered glass is not easily broken by the impact received from the outside because the fixed state of the tempered glass is solid, and how the top plate and the finishing frame are combined is unknown from the outside. Therefore, it is impossible to separate it arbitrarily, so there is no problem such as students separating and damaging it out of curiosity, so there are useful effects such as improving the durability of the desk top plate.

Hereinafter, preferred embodiments that do not limit the present invention will be described in detail with reference to the accompanying drawings.

1 to 8 show a desk 1 according to an embodiment of the present invention, which is a desk in which a top plate 10 covered with tempered glass 20 is attached to a frame 50; The upper plate 10 has a rectangular shape, and reinforcing ribs 12 are formed at a predetermined height so that the tempered glass 20 is placed on the inside thereof, and protruding frames 14 are formed lower than the reinforcing ribs 12 on the outer edge of the upper plate 10. The upper surface portion 32 covering the periphery and the closing frame 30 having the side portion 34 extending downward from the outer edge of the upper surface portion 32 and covering the side surface of the top plate are combined, and hook grooves 36 into which the elastic hooks 16 are inserted are formed at regular intervals inside the side surface portion 34 of the finishing frame 30, and between the hook grooves 36, the closing frame 30 is caught on the inside of the protruding frame 14 A locking protrusion 38 is formed to prevent peeling off.

Reference numeral 40 in the drawing is a storage stand coupled to the lower side of the top plate 10, for storing books or notes, etc. under the top plate 10, and reference numeral 60 is a storage table 40 and top plate 10 to the frame 50. It is a bolt for fixing.

In this embodiment, reinforcing ribs 12 for supporting the tempered glass 20 are protruded from the top surface of the top plate 10 in a lattice shape to minimize the amount of synthetic resin used as the material of the top plate 10 to reduce material costs and at the same time lighten the weight of the top plate and prevent deformation such as distortion of the molded top plate. A bolt hole 13 for fastening with a bolt 60 is formed.

In the present embodiment, the reinforcing ribs 12 are shown as being made up of a lattice shape crossing vertically and horizontally, but the present invention is not limited thereto, and basically forms a lattice shape, but reinforcing ribs may be added in a diagonal direction at necessary portions, or in addition to the lattice shape, it is of course possible to form reinforcing ribs in various patterns, including honeycomb shapes.

In addition, in this embodiment, the protruding frame 14 formed on the outside of the top plate 10 is formed lower than the reinforcing rib 12 as shown enlarged in FIG. 0) serves to prevent the peeling off of the closing frame 30.

On the other hand, since the protrusion 38 is formed on the closing frame 30, if the closing frame 30 is damaged or is arbitrarily peeled off, the protrusion 38 is broken. In this case, since the elastic hook 16 of the top plate 10 and the protruding frame 14 are not easily damaged, only the closing frame 30, which is relatively light in weight and inexpensive to manufacture, can be used by combining with the top plate 10 again as a new one.

In addition, the protruding frame 14 is integrally formed with elastic hooks 16 having a predetermined width at regular intervals. As shown in FIG. 4, the elastic hooks 16 are generally formed with a width of about 2 to 3 cm, and a plurality of elastic hooks 16 are formed while going around the entire protruding frame 14 at a distance of about 10 cm, so that the integrally coupled state between the top plate 10 and the closing frame 30 can be firmly maintained. there is

In the drawing, reference numeral 16a denotes a hooking jaw at the top of the elastic hook 16, and reference numeral 17 is a support rib connected orthogonally to the inside of the elastic hook 16. The height of the support rib 17 is formed only to the lower side of the hooking jaw 16a, so that the hooking jaw 16a of the elastic hook 16 can enter the hook groove 36 while being in close contact with the inside of the side portion 34 of the closing frame 30 It is supported by force, and the hooking jaw 16a enters the hook groove 36 to stably maintain the hooked state.

Further, reference numeral 31 denotes a glass chin formed inside the upper surface portion 32 of the closing frame 30 so that the upper edge of the tempered glass 20 is fitted and hung.

As shown enlarged in FIG. 5, the closing frame 30 is hooked elastically on the top plate 10 so that the outer edge of the tempered glass 20 is pressed by the upper surface portion 32 to prevent separation, and the side portion 34 extending downward from the outer edge of the upper surface portion 32 covers the outer side surface of the top plate 10, and the elastic hook 16 formed on the outer edge of the top plate 10 is hook groove 36 inside. ) and at the same time, the locking protrusion 38 is caught on the protruding frame 14 formed on the outside of the top plate 10 to prevent the closing frame 30 from being arbitrarily peeled off.

On the other hand, the hooking protrusion 38 has a side part and an upper part connected to the inside of the side part 34 and the bottom surface of the top part 32 to be supported, effectively preventing the closing frame 30 from being peeled off, and at the same time serving as a kind of reinforcing rib that reinforces the structural strength between the upper surface part 32 and the side part 34.

In this embodiment, synthetic resin is used as the material of the upper plate 10 and the finishing frame 30, but the finishing frame 30 is made of a material having relatively better elasticity and tensile strength than the upper plate 10, so that it can exhibit stable durability despite long-term use. However, the material of the upper plate 10 and the closing frame 30 is not particularly limited.

Meanwhile, since the tempered glass 20 is generally made of transparent or translucent tempered glass, white or green paint is applied to the lower surface of the tempered glass 20 so that the reinforcing ribs 12 inside the upper plate 10 are not visible from the outside, or a separate soft opaque sheet or pad (not shown) is placed on the lower part of the tempered glass 20 to cover the reinforcing ribs 12 and at the same time prevent direct contact between the reinforcing ribs 12 and the tempered glass 20. Even if an impact is applied to the desk from the outside, the sheet may act as a kind of buffer material to prevent damage to the tempered glass due to the impact.

The desk top plate 10 of the present embodiment configured as described above can be assembled by injection molding the top plate 10 and the finishing frame 30 with synthetic resin, cutting the tempered glass 20 that meets this standard, and then placing the toughened glass 20 on the top plate 10 and pressing the closing frame 30 thereon to complete the assembly while the elastic hook 16 of the top plate 10 is elastically coupled to the hook groove 36 of the finishing frame 30 Bar, since its manufacturing and assembling process is very simple, it is possible to reduce the labor and time required for manufacturing and assembling, thereby lowering the manufacturing cost, and the tempered glass 20 is pressed as a whole on the reinforcing rib 12 of the top plate 10 by the closing frame 30, so that there is no risk of being arbitrarily separated from the top plate 10, and the tempered glass 20 placed on the reinforcing rib 12 even if a load is applied on the tempered glass 20. not easily damaged

As described above, the desk top plate of the present invention can be firmly fixed using a finishing frame so that the tempered glass does not separate from the top plate, and all four sides are surrounded by a finishing frame so that it is not easily damaged even when subjected to an external shock, so that the tempered glass can be prevented from falling out. Since the frame can be elastically coupled to the outside of the top plate, the appearance of the top plate is beautiful, but it is impossible to disassemble arbitrarily, so that it can be used stably for a long time.
