”形轨道来回滑动的升降滑动门，卷帘门以及折叠门等。The invention relates to a door panel used in a building, especially a multi-unit spliced door panel in which a finger protection structure and a sealing strip are used in garages, halls, shop windows and other occasions. The hinge structure and the sealing strip are spliced into a whole, which is suitable as the door panel of various types of dodge doors, for example, along the "

”-shaped track sliding back and forth sliding doors, rolling doors and folding doors, etc.

Background technique

The door panel is the main part of various dodge doors, and its structural form is not only related to the type of dodge door, but also directly affects the performance of the dodge door. Although the specific requirements of the door panels used in garages, halls, shop windows and other occasions are different, most of them adopt the door panel structure of multi-unit door panels. This kind of door panel is generally composed of several parallel door unit units hinged end-to-end along the upper and lower sides. For example, one kind of garage door that we often see is a rolling shutter type movable door, and the other is a track type lifting and sliding door, and the door panels generally adopt this structure.

For all multi-unit spliced door panels with finger protection structures and sealing strips combined side by side, the splicing structure between the door units is the key to its technology. However, for a multi-unit door panel with excellent performance, from the function From the aspect of use, it must have airtightness and thermal insulation; from the aspect of safety, it must have the safety of preventing fingers from being pinched; from the aspect of manufacture, It also requires a simple structure and is easy to process and manufacture. How to meet the above design requirements at the same time often gives designers a headache. The applicant once applied to the Patent Office of the State Intellectual Property Office on September 7, 2002 for an invention patent entitled "Multi-Unit End-to-End Door Panel Structure". 3. In terms of content, this patent is relatively close to the present invention, but the technical solutions are different, mainly in the design of the splicing structure between the door units. Judging from the current market development trend of multi-unit door splicing door panels, in order to design an ideal door panel structure, the key lies in how to solve the above problems, so that it can simplify the structure as much as possible and be easy to manufacture under the premise of ensuring performance. , reduce costs, and have market competitiveness. And the technical solution of the present invention is exactly the improvement and the further development that make on the basis of above-mentioned invention patent.

Contents of the invention

The present invention proposes a multi-unit spliced door panel with a new type of finger protection structure and sealing strip combined side by side. Its purpose is to provide a technical solution with simple structure, convenient manufacture, good safety, outstanding performance and practical value. Solve the comprehensive technical problems of multi-unit door splicing such as turning, sealing and heat preservation, safety and ease of processing.

In order to achieve the above purpose, the technical solution adopted by the present invention is: a multi-unit spliced door panel combined with a finger protection structure and a sealing strip side by side, with the same shape and structure as the unit, and at least two door units in the order of front and back Arranged and connected along the head and tail hinges between adjacent door units to form a door panel structure that can be turned along the hinge axis. The innovation lies in:

At the joint of two adjacent door units, the door unit is divided into two parts, the inner half and the outer half in the thickness direction, wherein the outer half is designed as a sealing structure, and the inner half is designed as a push-finger protection structure;

The sealing structure is: the tail of the first unit is opposed to the outer half of the head of the second unit to form a gap larger than the width of an adult's finger, and a hollow or solid flexible sealing strip is arranged in the gap, and the flexible sealing strip is opposite to the tail of the first unit. Or the head of the second unit is fixed, and the flexible sealing strip contacts the outer halves of the two door units when the door panel is closed, and relatively fills the gap to form a sealing structure;

The push finger protection structure is as follows: the inner half of the tail of the first unit is provided with a concave part, and the concave part is formed by a concave step end surface or an arc surface or an inclined surface; the inner half of the head of the second unit is provided with a convex part, and the convex part is formed The top end is an arc or slope, and the hinge axis is eccentrically arranged on the inside of the door unit, and the concave part is close to the arc or slope of the convex part and rotates relatively to form a push finger protection structure; the convex part on the inner half of the first part of the second unit The upper part is formed by sheet metal folding or forming, and is inlaid and fixed on the position of the inner half.

The relevant content in the above-mentioned technical scheme is explained as follows:

1. The "unit" refers to the basic door sheet that constitutes the door panel, and the multi-unit refers to a door panel composed of at least two or more door sheet units.

2. End-to-end splicing means that when many door pieces are placed on a plane in sequence, the first edge of one door piece is connected to the tail edge of another door piece through a hinge structure.

3. The "outer halves facing each other to form a gap larger than the width of an adult's finger" is one of the necessary technical features of this solution. It not only has a concept of quantity, but also reflects the essential difference from the prior art. From the perspective of quantity, the width of the gap is wider than that of an adult's finger, but its essence and purpose is to solve the problem of pinching fingers. However, setting a flexible sealing strip in the gap can ensure the sealing effect. Therefore, when we understand the present invention, we cannot simply compare distances, but should distinguish them essentially.

4. The "flexible sealing strip" is one of the splicing components between the door units, and it works together with the hinge structure to connect the doors. For the hinge, its function is to realize a rotating connection relationship, and for the sealing strip, its function is: first, to cooperate with the hinge to realize a flexible connection; second, to play a sealing role; third, to obtain a decorative effect, these Function and effect are very important to a door panel product. As for the cross-sectional shape of the sealing strip, there can be many variations, as long as these variations do not involve creative work for those of ordinary skill, they should all belong to the scope of protection of the present invention.

5. In the above scheme, the concept of "inside" and "outside" refers to the side of the door panel facing the indoor direction, and the outside refers to the side of the door panel facing the outdoor direction.

6. In the above solution, the flexible sealing strip fills the gap when the door panel is closed, which is a relative concept. Judging from the judgment, as long as the flexible sealing strip fills up or almost fills the gap when the door panel is closed, This requirement is relative to the use of thin strips or thin sheets in the prior art, because the use of thin strips or thin sheets cannot guarantee the sealing performance, especially there will be voids between the two ends of the sealing strip and the door frame. On the other hand, it is also unfavorable for appearance that there are empty grooves at the splicing place of the whole door panel.

7. In the above solution, the tail of the first unit and the outer half of the head of the second unit are preferably perpendicular to the plane of the door panel, and the two planes face each other to form a parallel gap larger than the width of an adult’s finger, which is the simplest. Of course, it is not ruled out that a non-vertical shape is designed.

8. In the above scheme, the flexible sealing strip can be a hollow structure or a solid structure, and there are many ways to fix it, among which, the first type is fixed next to the convex part of the head of the second unit; the second type is fixed On the end of the first unit. In each type, different fixing methods can be used for fixing.

9. In the above scheme, in order to give full play to the role of the flexible sealing strip in the entire product, further changes and utilization can be made on the basis of the sealing strip. The specific content is as follows:

(1) Apply color coating on the front of the sealing strip facing outward, so that the sealing strip not only plays a sealing role, but also has a decorative effect of color lines, making the door panel look more beautiful.

(2) Apply a reflective coating on the front of the sealing strip facing outwards, which will be very eye-catching when the car light shines at night.

(3) Apply a fluorescent coating on the front of the sealing strip facing outwards, which can produce a fluorescent effect at night.

(4) Light-emitting diodes are arranged at intervals along the length direction on the sealing strip, and all the light-emitting diodes are connected to the power supply through wires. The light-emitting diodes can be embedded in the sealing strip, or the sealing strip can be made into a transparent tubular structure, and then the light-emitting diodes can be placed in the pipe. The luminescence of the diode can be in the form of flickering, and can also be in a variety of transformation forms, which are all controlled by the circuit, so that the control circuit and the connection mode of the light-emitting diode adopt the currently known prior art. Another solution is to link the control of the LED with the opening or closing working status of the movable door, and realize it through the remote control of the movable door or the manual door lock. When the garage door is opened or closed, the LED lights up and delays for a period of time , it can also be that the diode lights up when the garage door is opened and stops when the garage door is closed. In short, the use of light-emitting diodes not only indicates the working status of the garage door, but also can be used as night decoration.

(5) On the sealing strip, light bulbs are arranged at intervals along the length direction, and all the light bulbs are connected to the power supply through wires. The use of light bulbs is similar to that of light emitting diodes, and the description will be repeated here.

The principle of the invention is: at the joint of two door units, the thickness direction of the door is divided into an inner half and an outer half, and a gap larger than an adult's finger and a flexible sealing strip are designed between the outer halves of the two units. The sealing structure constitutes, the sealing structure provides sealing function and anti-pinch finger function at the same time (since the gap is larger than the adult's finger, even if the finger is put into the gap, the finger will not be pinched); between the inner half of the two units, a convex structure is designed. The push finger protection structure that rotates and cooperates with the concave part and the push finger protection structure simultaneously provides the push finger protection function and the tamper-proof safety function. Since the sealing structure and the push-finger protection structure are used side by side at the splicing of the door unit, a multi-unit splicing door panel with simple structure, convenient manufacture, good safety, outstanding performance and practical value is obtained.

Due to the use of the above-mentioned technical solutions, the present invention has the following advantages and effects compared with the prior art:

1. The present invention has made great progress in terms of sealing performance, finger protection and safety, especially the combination of double-layer functions has achieved better results, that is, the sealing function and anti-pinch provided by the sealing structure The finger function, combined with the finger protection function provided by the push finger protection structure and the anti-pry safety function, has obtained unexpected effects, and has outstanding substantive features and significant technological progress.

2. Another advantage of the splicing structure of the door panel of the present invention is that the door panel gap can be used to insert fingers into the gap to close the door panel without pinching fingers, which saves the need to install handles on the outside of the door panel, and is very convenient to operate. In the prior art, for a manual door panel, at least one handle must be installed on the outside of the door panel, and for an automatic door panel, at least one handle must be installed on the outside of the door panel in order to facilitate manual operation in a power failure state.

3. The structure of the present invention is simpler than before the improvement, the processing and assembly requirements of the door panel are lower, and it is easier to manufacture, which is conducive to reducing production costs and improving market competitiveness.

4. The present invention skillfully integrates the functional design and the structural design at the splicing part of the door unit, which makes the technical scheme unique in conception and fully reflects the rationality of its overall design.

5. The present invention utilizes coatings, light-emitting diodes and other structures to rationally and effectively utilize the void space, and further expands the practicability and functions of the door panels, which plays a positive role in enriching the design of garage doors and produces obvious effects.
