Description

Technical Field

[0001] The present invention belongs to the technical field of balustrade fittings, in some embodiments thereof, relates to a clamping system for mounting glass balustrade.

Background of the Invention

[0002] The frameless glass balustrade enjoys a modern, simple and attractive appearance, and is widely applied to architectural fence. In general, two methods are employed to fix the present frameless glass balustrades. In one of the method, a U shaped channel is utilized in order for the fixing. The opening of the U shaped channel is of a fixed value, but for different glass panes with different widths, the widths of channel may vary. In this way of fixing, several defects are founded: 1. lack of popularity; 2. lack of ability to resist pushing force, difficulties of installing and the increase of cost for thickening the steel plate of the U-shaped channel to enhance the push-resist strength; 3. strict angle demanding and difficulty of adjusting the glass after installation. While in the other method, the channel is strictly dug into the floor, into which the glass pane is inserted and the glue is injected. There are also some defects in this way: 1. more workload for digging the channel; 2. difficulties of changing the glass pane; 3. constrains imposed by the floor, some inadmissibility of fluting or drilling. In recent years, with the higher demands for artistic permeability of construction design, the glass balustrades are usually designed to be merely fixed at the bottom, with one side impending. In this case, it is very difficult to change the angle in the conventional two-sided manual adjusting way.

[0003] The utility model patent CN 201809915 U discloses an aluminum alloy frameless balustrade and a partition fixing system thereof. The plate fixing system includes a fixing base and an adjustable pushing base, which are fixed and connected by fasteners and making up a partition receiving part. Steel bars can be fixed into the base, while threaded holes can also be fixed on the steel bars. The fixing base and the adjustable pushing base can have through-holes respectively, and the fasteners can be the locking bolts, which stick through the through-holes of the fixing base and the adjustable pushing base and screw into the threaded holes on the steel bars. This structure is of good popularity, with no need to match the different fixing systems with glasses of different widths. But on the other hand, the structure is complex and thus inconvenient for installation. Most important is that, this structure cannot meet the demands of adjusting the angle of the glass. Besides, it cannot be easily dismounted, because of the glue injected in the late period.

[0004] The USA patent US14058337 discloses a wedge for clamping the glass balustrade, with the structure thereof to achieving the purpose of altering the distance between the glass and the inner walls of the U-shaped channel, by changing the width of the whole wedge through the opposite movement of two single-side wedge blocks which are housed opposite. The defect is that the angle of the glass is also unchangeable during installation.

[0005] The invention patent CN 201410108718.2 discloses a clamping system for mounting glass balustrade, including a base with a U-shaped channel, an adjusting component A and an adjusting component B. The adjusting component A comprising: an L-shaped Plate with an arc groove inside, fitting for an arc panel; an arc panel with longer arc-length than that of the arc groove in the L-shaped Plate. The adjusting component B comprising: a supporting plate with a trapezoid groove inside; a wedge A, a wedge B and an adjusting bolt; a hole channel on the middle top of the supporting plate, reaching through the trapezoid groove. Both the wedge A and the wedge B are single-side wedge structure. A threaded hole in the middle of the wedge A, which has internal thread matching with the adjusting bolt; the adjusting bolt, with top part screwing through the threaded hole of the wedge A, with the bottom part connecting with the wedge B; an embossing belt A on the two bevel surfaces of the trapezoid groove, paralleling to the center line of the trapezoid groove, symmetrical about the center line. This structure is easily dismounted, as well as allowing the angle of the glass changeable. Nevertheless, there are some defects as follows: 1. the thickness of adjusting component B is adjusted by rotating the adjusting bolt. However, the wedge A and the wedge B are connected by the same adjusting bolt, and therefore it is hard to adjust the wedge A or the wedge B separately to meet the needs of the actual situation; 2. the arc panel of the adjusting component A and the arc groove of the L-shaped Plate are sliding connected; if it needs to be adjusted at a big angle, the thickness of the adjusting component A will be too thick, which leading to a decrease in stability of glass installation.

Brief Summary of Embodiments of the Invention

[0006] In order to solve the prior technical problems, the invention discloses a new clamping system which can adjust the angle of glass easily, as well as ensuring the stability of glass installation.

[0007] The technical scheme of the invention is as below: a clamping system for mounting glass balustrade, including a base with a U-shaped channel, an adjusting component A and an adjusting component B. The adjusting component A comprising: an L-shaped Plate and arc panel. An arc groove inside of the L-shaped Plate is matched with the arc panel, with shorter arc-length than that of the arc panel. The adjusting component B comprising: a supporting plate with a trapezoid groove inside, a wedge A, a wedge B, an adjusting bolt A and an adjusting bolt B. Both the wedge A and the wedge B are single-side wedge structure, with one plane side and another bevel side. A hole channel is situated on the middle top of the supporting plate, reaching through the trapezoid groove; A horizontally placed locating element is situated in the middle of the trapezoid groove. A threaded hole A is in the middle of the wedge A, which has internal thread matching with the adjusting bolt A. The top part of adjusting bolt A, screws through the threaded hole A of the wedge A, connecting with the Wedge A, and bottom part of adjusting bolt A connects with the locating element permanently. A threaded hole B is situated on the other side of the locating element that away from the adjusting bolt A, with internal thread fitting for the adjusting bolt B. The top part of adjusting bolt B, screws through the threaded hole B of the locating element, connecting with the locating element, and bottom part of adjusting bolt B connects with the wedge B permanently. The arc panel embedded into the arc groove of L-shaped plate can slide up and down freely, without sliding out of the arc groove.

[0008] The other optimal scheme of the invention is as below: a clamping system for mounting glass balustrade, including a base with a U-shaped channel, an adjusting component A and an adjusting component B. The adjusting component A comprising: an L-shaped plate and a trapezoid plate that inside the L-shaped plate. Both the two ladder surfaces of the trapezoid plate are symmetrical arc convex surfaces of the same arc; A trapezoid groove is configured in the inner side of the L-shaped plate, which matches with the trapezoid convex surface of the trapezoid plate, with shorter length than that of the trapezoid convex. The adjusting component B comprising: a supporting plate with a trapezoid groove inside, a wedge A, a wedge B, an adjusting bolt A and an adjusting bolt B. Both the wedge A and the wedge B are single-side wedge structure, with one plane side and another bevel side. A hole channel is situated on the middle top of the supporting plate, reaching through the trapezoid groove; A horizontally placed locating element is situated in the middle of the trapezoid groove. A threaded hole A is in the middle of the wedge A, which has internal thread matching with the adjusting bolt A. The top part of adjusting bolt A, screws through the threaded hole A of the wedge A, connecting with the Wedge A, and bottom part of adjusting bolt A connects with the locating element permanently. A threaded hole B is situated on the other side of the locating element that away from the adjusting bolt A, with internal thread fitting for the adjusting bolt B. The top part of adjusting bolt B, screws through the threaded hole B of the locating element, connecting with the locating element, and bottom part of adjusting bolt B connects with the wedge B permanently. Both the two bevel surfaces of the trapezoid groove are arc embossing surfaces. The arc panel embedded into the arc groove of L-shaped plate can slide up and down freely, without sliding out of the arc groove. The adjusting component A adopts the trapezoid plate instead of an arc panel, during doing the same angling, the structure of this scheme reduces the thickness of the adjusting component A, therefore improves the stability of the glass installation.

[0009] Protruding parts are on the top of the trapezoid plate of the adjusting component A, while slots at the corresponding position on the top of the L-shaped plate, the height of the slots is higher than that of the protruding parts, and the width of the slots is slightly wider than that of the protruding parts. The trapezoid plate embedded into the L-shaped plate by the protruding parts, can slide up and down freely, without sliding out of the trapezoid groove.

[0010] A contacting part of the L-shaped plate and the trapezoid plate is a hollow frame structure. A sliding block is in the middle of the frame structure lengthwise, while a slide-way in the trapezoid plate is at the corresponding position to the lengthwise frame/ block. The width of the slide-way is slightly wider than that of the lengthwise frame/sliding block. Due to the setting of the lengthwise frame/sliding block and the slide-way, which can reduce the contact area of the trapezoid plate and the L-shaped plate, thereby decrease the frictional resistance of sliding, as well as save the materials and cut down the production cost.

[0011] In another variant, a slot A is situated on the top of the locating element; A blocking foot is at the end of the adjusting bolt A, fitting for the slot A, connecting with the locating element by assembling the blocking foot and the slot A; a slot B is at the end of the wedge B; a blocking foot at the end of adjusting bolt B, fitting for the slot B, connecting with the wedge B by assembling the blocking foot and the slot B. A hexagon socket is on the top of the adjusting bolt. Supporting feet are at the bottom of the supporting plate. Steel panels are installed at the bottom of the slot A and the slot B to enhance the strength.

[0012] In still another variant, a drain hole is under the bottom of the L-shaped plate for drainage.

[0013] In yet another variant, an arc embossing belt B is configured on the bottom of the L-shaped plate, which can facilitate the glass sliding on the L-shaped plate during adjusting the installing angle of glass.

[0014] When installing the glass balustrade, the adjusting component A is put into the fixed U-shaped channel, making the L-shaped plate against the wall of the U-shaped channel. Then the glass is put inwards, making the glass against the plane surface of arc panel / trapezoid plate completely. Then a magnet and a magnetic spirit level are attached to each side of the glass for the use of observing the horizontal plane. The glass is angled to keep vertical with horizontal plane, by the measure of sliding the arc panel /trapezoid plate which is clung to the glass in the trapezoid groove. Afterangling, the adjusting component B is put inside. By wresting the wrench and making the adjusting bolt A and adjusting bolt B rotated clockwise, the wedge A and the wedge B make backwards movement, and then the thickness of the adjusting component B is enhanced till it can fasten the glass. The wedge A and wedge B only contact with the arc embossing surfaces A on the bevel surface of the trapezoid groove, therefore the pressure from the wedge A and wedge B during their moving can only apply to the arc embossing surfaces A which located symmetrically with the center line of the trapezoid groove. During the backwards movement of wedge A and wedge B, the force point doesn't change with the movement of wedge A or wedge B, and thus it can guarantee the force delivered from the glass to the trapezoid plate keeping balance, which can prevent the trapezoid plate from sliding due to the asymmetrical force bearing.

[0015] If there is a deviation during the process of glass clamping, the adjusting bolt A / the adjusting bolt B can be rotated to adjust the clamping force of the wedge A/the wedge B against to the glass, thereby changing the angle of the glass; after adjusting the glass to the right angle, the glass can be clamped by rotating the he adjusting bolt.

[0016] When dismounting of the glass balustrade, by twisting the adjusting bolt A and the adjusting bolt B anticlockwise, the wedge A and the wedge B make the opposite movement, and then the thickness of the adjusting component B is reduced to unfix and release the glass.

[0017] The invention has the beneficial effects that:

1. the support plate of the adjusting component B connects two tapered wedges with two bolts, the bolts can be rotated to control the tapered wedges moving up and down separately; operating by a hexagon wrench, it is not only easy to install or dismount, but also easy to adjust the glass angle during installation.

2. the adjusting component A adopts the trapezoid plate and the L-shaped plate with a trapezoid groove inside, compared with the arc panel, the curvature of the trapezoid plate increases; therefore, when doing the same angling, this structure reduces the thickness of the adjusting component A, improves the stability of the glass installation.

3. the adjusting component A and adjusting component B have large contacting area with the glass, thus the clamping is stable and the pressure is well-distributed;

4. by angling the glass through the arc panel, the error aroused by the uneven of the floor is eliminated, making the glass vertically installed which is fastened by the wedge structure;

5. the glass can be fastened and angled only at one side, which increases the working efficiency, especially on the condition that the glass balustrade is impending settled, therefore it is more convenient for application
