Description

Buffer device and door comprising same

Technical Field

The utility model relates to the technical field of door functions, in particular to a buffering device and a door comprising the same.

Background

With social progress and scientific development, the technical level of products in China is continuously improved. Doors with cushioning create a large market demand. However, the applicant finds that most of the buffer devices adopted by the existing doors with buffer functions are buffer self-closing hinges or door closers, and the buffer self-closing hinges are provided with buffer structures on hinges, so that the structure is complicated and the cost is high. As shown in fig. 1, the door closer is a spring-like hydraulic member installed on the upper portions of the door body 1 and the door frame 2, and is capable of automatically closing the door by being released after being compressed when the door is opened, and has a buffering effect. However, the hydraulic component structure is partially exposed outside the door after the door is closed, the overall effect of the door is damaged, the appearance is not attractive, and the installation of the opening is troublesome.

Therefore, how to achieve the buffering effect of the door body in the automatic closing process in an attractive, effective and simple manner has certain research significance.

Detailed Description

Exemplary embodiments will now be described more fully with reference to the accompanying drawings. The exemplary embodiments, however, may be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As shown in fig. 2, the damping device of the present invention includes a damper 3 and a damping chute 4, wherein the damper 3 is disposed on the upper portion of the door frame 2, and the damping chute 4 is disposed on the upper end of the door body 1. The structure thereof will be specifically described below with reference to fig. 2. The damper 3 is installed on the upper cross member 21 at the upper portion of the door frame 2, and for the sake of beauty, the damper 3 may be provided on the lower end surface of the upper cross member 21 so as not to be exposed to the outside when the door body 1 is closed. The damper 3 may be mounted on the lower end surface of the upper cross member 21 by, for example, screwing, bonding, or the like, such that the damper 3 extends downward to form a certain cushioning contact portion 31, and the cushioning contact portion 31 extends out of the lower end surface of the upper cross member 21. The damper 3 may be formed integrally with the door frame, for example, the damper may be assembled integrally with the door frame in a factory in advance, or the damper 3 may be installed after the door frame is installed. The specific form of the damper 3 is not limited, and it may be, for example, a rubber body.

The buffer chute 4 is arranged at the upper end of one surface of the door body 1, specifically, the buffer chute 4 is arranged at the top surface of the door body 1 and at the upper end of the panel on one side of the closing rotation direction of the door body. The buffer sliding chute 4 is used for contacting and matching with the buffer contact part 31 of the damper 3, when the door is closed under the action of the self-closing force F, and the door body 1 is closed, the buffer sliding chute 4 and the door body 1 rotate together to be contacted with the buffer contact part 31, so that the door body 1 is decelerated in the contact process of the buffer contact part 31, and the buffer effect is achieved. It should be noted that the self-closing force F is merely exemplary, and may be a manual door closing.

Further, in order to have a better effect of compressing the damper, the groove bottom 41 of the buffering chute 4 is gradually raised on a tangent plane perpendicular to the panel surface of the door body 1. As shown in fig. 3a to 3c, when the door is closed by the self-closing force F, fig. 3a shows that the buffer contact portion 31 just enters the buffer chute 4 and contacts with the bottom of the buffer chute 4, so that the door body 1 starts to decelerate; fig. 3b shows that the buffer contact portion 31 is gradually compressed to a certain extent during the sliding of the buffer slide groove 4 while the door body 1 continues to move toward the door frame 2; fig. 3c shows the door body completely moved to the closed state, and the buffer contact portion 31 is completely compressed. Through the in-process that the door body 1 closed, compress attenuator 3 gradually, and then make the door body 1 slowly close, avoid the noise that the lock or the door body and door frame 2 impact production fast, play the effect of buffering damping silence.

The buffer slide 4 may compress the buffer contact portion 31 in another form, for example, a side wall of the buffer slide 4 may be formed in a slope so that the buffer contact portion 31 is compressed during the contact.

The buffer chute 4 may be a groove having a buffer effect, for example, a bottom of the groove may be wavy, but the groove may have a compression buffer effect, although the effect is not as good as the effect of gradually ascending and gradually compressing.

In addition, the damper is arranged on the upper cross beam at the upper end of the doorframe as an example, the damper is not excluded from being arranged at other positions of the doorframe as long as the damper extends beyond the inner side surface of the doorframe, and the extending of the doorframe refers to the surface of the damper extending beyond the installed position from the installed position. For example, the door frame may be provided at an upper portion of a pillar of the door frame (the door frame includes two pillars and an upper beam 21 connected to an upper portion of the pillars), and the door body may be provided with a buffer chute corresponding thereto.

The above-mentioned buffering devices may be provided in plural on the door body and the door frame, and the installation manner is the same as that described above, and will not be described in detail here.

In addition, the damper and the buffer chute can be exchanged in position, specifically, the damper can be arranged on the door body, the damper extends beyond the side face of the door body (the side face refers to four faces except two plate faces), and the lower side face is not the most suitable installation position. The buffering chute can be arranged on the door frame. The buffering chute is on the tangent plane of perpendicular to door frame place plane, to closing the door rotation direction, and the buffering chute shrinks gradually.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
