Description

Pressure-reducing buffering leather pad

Technical Field

The utility model relates to the technical field of furniture, concretely relates to decompression buffering leather mat.

Background

The seat cushion or leather cushion is an accessory part of a table and a chair and is generally fixedly arranged on a support of the table and the chair so as to be used for people to sit. A conventional seat cushion generally comprises three layers, namely an uppermost surface layer, a middle breathable layer and a bottom layer. The upper layer, the middle layer and the lower layer of the leather cushion are fixedly connected together, have a certain buffering function and can bring comfortable feeling to people sitting on the table and chair.

The utility model discloses a utility model patent of grant bulletin for CN202491706U discloses a seatpad, and it includes seatpad surface course, ventilative layer and seatpad bottom. The air-permeable layer is composed of pipelines which are arranged in a grid shape and provided with air inlets. Through the gas inlet, send into ventilative layer with cold air, heating installation or natural air, can adjust the temperature of whole seatpad. The whole seat cushion has simple structure and good ventilation effect.

The seat cushion can adjust the temperature of the seat cushion, has good integral ventilation effect, but does not have the function of decompression and buffering. Once the weight suddenly presses on the surface layer of the seat cushion, strong impact is easily caused to the air-permeable layer and the bottom layer, thereby reducing the service life of the seat cushion.

Preferably, the leather pad surface layer comprises a leather sleeve and a sponge, and the leather sleeve is arranged on the sponge.

Preferably, the groove is in a concave shape gradually decreasing from the periphery to the center, and a hole is formed in the most central position of the groove.

Preferably, the leather pad surface layer and the breathable layer are glued.

Preferably, the lower end of the square groove is closed.

Due to the adoption of the technical scheme, compare with prior art, the utility model discloses following beneficial effect has:

carry air conditioning or heating installation toward ventilative layer through the air inlet, can adjust the temperature of leather mat to bring comfortable impression for the user.

And coil spring and aperture from top to bottom degressive exhaust hole's existence gradually in the recess, can play the effect of a decompression buffering to ventilative layer and leather pad bottom well, avoid the heavy object to lead to the fact strong impact to ventilative layer and leather pad bottom to the life of extension leather pad.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiment of the present invention, all other embodiments that a person skilled in the art can obtain without creative work all belong to the protection scope of the present invention.

As shown in fig. 1, decompression buffering leather mat, including leather mat surface course 1, ventilative layer 2 and leather mat bottom 3, leather mat surface course 1 is located on ventilative layer 2, ventilative layer 2 is located on leather mat bottom 3, be equipped with one in the leather mat bottom 3 with ventilative layer 2 size assorted recess 4, be equipped with a plurality of coil spring 5 in the recess 4, coil spring 5's lower extreme and recess 4 fixed connection, its upper end meets with ventilative layer 2, the lateral wall all around of recess 4 is equipped with a plurality of exhaust hole group 6, exhaust hole group 6 includes a plurality of exhaust hole 7, the aperture of exhaust hole 7 from top to bottom descends gradually, be equipped with the air inlet 8 that is used for carrying air conditioning or heating installation on the lateral wall of ventilative layer 2.

A set of exhaust holes 6 is provided along the side wall of the groove 4, around the center of the groove 4, and includes a plurality of exhaust holes 7. The number of the vent holes 7 should be set as much as possible according to the height of the groove 4. When the air-permeable layer 2 moves downward by a strong impact, the air in the grooves 4 is inevitably discharged from the air discharge holes 7. Because the aperture of exhaust hole 7 diminishes gradually from top to bottom, ventilative layer 2 can receive an upward reaction force, and ventilative layer 2 is more down moreover, and this reaction force is big more. Therefore, the air vent group 6 can reduce the impact on the air-permeable layer 2 to a large extent by engaging the coil spring 5.

In order to better exert the decompression and buffering functions of the vent hole group 6 and the spiral spring 5, the peripheral edges of the ventilation layer 2 and the groove 4 are connected in a sealing mode. For this purpose, a rubber sealing layer may be provided around the circumferential edge of the recess 4.

The bottom surface of the breathable layer 2 is sealed in a closed manner, the spiral spring 5 is connected to the bottom surface of the breathable layer 2, and in a normal state, namely a natural extension state of the spiral spring 5 under the gravity of the breathable layer 2 and the leather pad surface layer 1, the height of the spiral spring 5 should be smaller than that of the groove 4.

The air-permeable layer 2 can be composed of a plurality of square grooves 9 which are distributed in a grid shape, the lower ends of the square grooves 9 are closed, and the upper ends of the square grooves 9 are glued with the leather pad surface layer 1 to form a closed space. The ventilation holes 10 are formed between the adjacent square grooves 9, and the cold air or the warm air supplied from the air inlet 8 can be quickly and uniformly distributed between the square grooves 9 through the ventilation holes 10.

Further, the leather mat face layer 1 may be divided into two layers. The upper layer is a leather sheath 11 made of PU leather or microfiber leather and the like, and the lower layer is a sponge 12 capable of playing a certain role in buffering and heat preservation.

When the leather mat is placed outdoors, rainwater may flow into the groove 4 from the exhaust hole 7. Rainwater is accumulated in the groove 4, and if the rainwater cannot be discharged in time, bacteria and mosquitoes are easy to breed. To solve this problem, the groove 4 may be formed in a concave shape gradually decreasing from the periphery toward the center, and then a hole 13 for air discharge and drainage may be provided at the center of the groove 4.

The above all be the utility model discloses a preferred embodiment, the utility model discloses a protection scope does not confine above-mentioned embodiment to, the all belong to the utility model discloses other technical scheme under the thinking all belong to the utility model discloses a protection scope. It should be noted that various modifications and decorations made by those skilled in the art without departing from the principle of the present invention should be considered as the protection scope of the present invention.
